Conventionally, the procedure for brewing tea with a teapot made of pottery has been generalized. That is, hot water of a constant temperature is poured into the storage part of the teapot, and a tea strainer or the like is inserted into the storage part to throw in tea leaves, or in a configuration in which a tea strainer is provided at the spout, the tea leaves are directly contained in the storage part. Is directly input. In this case, the characteristics of tea leaves, the temperature of hot water, the leaching time, etc. are all controlled by human senses, and considerable skill is required to brew delicious tea, and people with low skill level are delicious. It is difficult to get the taste of tea.

The device for automatically brewing tea disclosed in Patent Document 1 described above sets a container containing water in a predetermined position, and automatically raises and lowers the tea leaf net containing tea leaves with respect to the opening of the container. The structure is such that the tea is brewed by inserting / discharging it into the container, and the structure becomes complicated and large-scale, such as the need for an elevating mechanism for the tea leaf net. You can't get the feeling of brewing tea. That is, the structure and operation procedure of the device itself are complicated, and it is not a device for easily brewing delicious tea with a kyusu as in the past.

The teapot disclosed in Patent Document 2 described above includes a sensor that measures the temperature of water in the main body of the teapot that holds water and pours tea, a display unit that displays the temperature detected by this sensor, and a setting of hot water. Since it has a configuration that incorporates a control unit such as an input unit for inputting the temperature and set time, and a notification unit for notifying when the set temperature or set time is reached, the teapot is not easy to handle and operate, and is as easy as a conventional teapot. It is not a structure for brewing delicious tea. In addition, it is not possible to brew delicious tea because it is not possible to grasp the state of tea leaching inside the main body. Further, the method of turning off the heat source and notifying when a predetermined value is detected by the temperature sensor does not control the temperature of hot water to a constant value, and tea cannot be brewed at an appropriate temperature. That is, even if the power is turned off when the temperature sensor detects a predetermined temperature, the temperature rises due to the subsequent residual heat, and when the tea leaves are actually put in, the temperature is high against the delicious temperature conditions. As a result, delicious tea cannot be brewed.

The tea leaf extraction device disclosed in Patent Document 3 described above steams tea leaves above heated water, then immerses the tea leaves in heated water, measures the immersion time, and measures the tea. It is a so-called French press type configuration that notifies the extraction of. With such a configuration, the tea leaf extract can be extracted quickly (the time for brewing tea can be shortened), but the exact time for leaching the components cannot be grasped. For delicious tea, it is important to be able to accurately grasp the time from when the tea leaves begin to absorb water at the most suitable temperature until the extract is extracted.

In addition, it makes it easy and accurate to grasp the time from when the tea leaves start to absorb water at a suitable water temperature until the extract is extracted (the optimum time for adding the dried tea leaves and leaching the extract). Therefore, it is not possible for a skilled person to obtain delicious tea that is brewed using a teapot. In particular, when tea leaves are steamed above gradually heated water, the tea leaves continue to absorb water from the low temperature state until the water is heated, and the amount of water absorption changes depending on the amount of tea leaves and the amount of water. After that, even if the steamed tea leaves are immersed in heated water, it is not possible to brew stable and delicious tea. That is, the tea leaf extraction device disclosed in Patent Document 3 is characterized in that the tea leaf extract is quickly extracted, and no one can easily brew delicious tea.

As described above, the known tea leaf extraction device has a complicated structure and operation procedure, and has a feeling of use (operation procedure) similar to that of a general pottery teapot, and is easy and easy to use. It does not provide a structure that can serve delicious tea. Even if you are not an expert, in order to brew delicious tea, the hot water must be at the proper temperature when leaching the ingredients of the tea leaves, the temperature does not change when the ingredients are leached, and the dried tea leaves are dried. It is important to accurately grasp the leaching time of the components after the tea is added.

The present invention has been made by paying attention to the above-mentioned problems, and is an expert in a kyusu used for leaching an extract from various plant materials such as tea leaves (green tea, black tea, etc.), flowers, fruits, roots, etc. Even if it is not, the purpose is to provide a kyusu that enables delicious brewing with a simple structure and a simple operation procedure.

It is configured to have a base having a function of maintaining a predetermined temperature. For this reason, the container part functions in the same way as a conventional pottery teapot, and instead of putting the hot water directly into the container, the water is stored in the container to reach the set temperature (optimal temperature for tea leaves). Hot water is obtained in the container by the base to be heated.

In order to brew delicious tea, it is necessary to accurately control the temperature of hot water and the leaching time depending on the tea leaves used, and the desired taste of double water specified by the amount of water and the amount of dry tea leaves. It is necessary to control the temperature associated with the temperature (also referred to as the set temperature or the target temperature) and accurately control the leaching time of the component specified by the double water. With conventional pottery teapots, hot water is boiled in a pot, etc., hot water at the optimum temperature is put into the teapot, and then tea leaves are added to achieve the optimum leaching time. In order to brew, some skill is required. On the other hand, in the present embodiment, it is configured so that anyone can brew delicious tea with a simple operation procedure by a simple device configuration without requiring such a skillful technique. That is, the kyusu according to the present invention is water that leaches tea leaf extract (not limited to fresh water, but carbonated water) with a simple operation procedure (one-way operation that does not require complicated operations) without any mistakes.

It is provided with a RAM 83 for temporarily storing various information in executing the above, a timer 84 for time management (management of component leaching time of tea leaves, etc.), and the like.

The above-mentioned functions of the operation panel 51 (mainly functions as an operation unit and a display unit) may be performed by an operation device other than the base 50. For example, a transmission / reception unit (communication unit) is incorporated in the base 50, and an operation signal or an operation signal can be transmitted to and from a mobile terminal such as a smartphone by using an existing communication network such as WiFi or Bluetooth (registered trademark). Information signals may be transmitted and received so that external operations can be performed. That is, the mobile terminal owned by the user may be provided with a function as an operation unit or a display unit, or may be provided with a function as a notification means (sound, light, vibration, etc.) for notifying the tea leaf component leaching time. ..

Next, using the above-mentioned teapot 1, the flow of the entire operation from putting water in the container 10 to brewing tea will be described with reference to the flowchart of FIG. As described above, when the user brews tea using the Kyusu 1, the control unit 80 of the present invention can brew delicious tea with a simple operation procedure (one-way operation) without making an operation error. It is configured to execute possible procedures.

As the first preparation, connect the outlet of the power supply unit 71 to the household power supply, and place the container 10 containing water on the base 50. The amount of water may be measured and stored in a lightweight cup by the user, or a scale for the amount of water may be provided in the container and the user may store the water while looking at the scale. Regarding the amount of water, specify the amount of tea leaves to be added and the amount of double water to be brewed.

When the power switch key 53 is pressed (long press operation), the power is turned on, preferably a sound is generated and the power is turned on (S1). As a result, the temperature setting mode that can be input by the user is set, the temperature display unit 57 lights up, and the set temperature display unit 59 blinks (S2). In this case, the temperature display unit 57 displays the temperature previously set by the user (0 in the first use), and the displayed temperature can be changed by pressing the down key 54a and the up key 54b. It can be set (if the temperature is the same as the previous one, it can be left as it is). That is, after the device is turned on, the control unit 80 accepts the operation of setting / changing the heating temperature, and the temperature display unit 57 displays and sets the actual set temperature and the change of the set temperature. The numerical value of the temperature is displayed on the temperature display unit 57.

Next, the control unit 80 receives the operation of the heating start key 55 of the user, and when there is a pressing operation, supplies the electric power from the power supply unit 71 to the heating body 12 to perform heating (S3).
When the heating starts, a sound is preferably generated, the current temperature display unit 60 lights up, and the temperature display unit 57 displays the current temperature (actual temperature of water in the container). Further, during heating (power is being supplied to the heating body 12), the temperature display unit 60 is currently lit (blinking) (S4).

Along with the operation of the heating start key 55, the time display unit 58 blinks, and the time setting change can be accepted (S5). That is, the control unit 80 controls to accept the operation related to the notification time set by the user after the heating of the water is started.
The time setting here is for the user to set the optimum time for the extract to leaching after the tea leaves are added to the water at a predetermined temperature (the time is notified by a timer), so-called. Ingredient leaching time. With respect to component leaching, both countdown and countup can be freely selected, and the user selects either countdown mode or countup mode by pressing the down key 54a and the up key 54b. It is possible to set the time. In this case, in the

time display unit

58, 0 is displayed when the user is in the specific time (countdown time) set last time or in the countup mode, and the displayed time is down. It is possible to change and set by pressing the key 54a and the up key 54b. Therefore, if the notification time is the same as the previous time, it can be left as it is.

This set time is displayed on the time display unit 58, and the user is activated by operating the time start key 56 at the same time as the tea leaf is thrown in, and in the countdown mode, when it reaches 0 seconds. In addition, the user is notified by means of notification such as sound, light, and vibration. If the user desires the count-up mode, the down key 54a and the up key 54b are pressed to display "0" on the time display unit 58, so that the count-up mode is set and the user can use the tea leaves. By operating the time start key 56 at the same time as pressing, the time is counted up from 0 seconds.
By operating the heating start key 55 in this way, it is possible to perform an operation for setting the time and a start (timer activation) operation for the set time.

In the present embodiment, after operating the heating start button, the control unit does not accept the temperature setting operation and performs an operation of turning the power on / off or an operation of removing the container 10 from the base 50 and returning it to the original state. , Although the temperature setting operation is accepted, it may be possible to immediately return to the temperature management operation (set temperature mode) from the time management operation state. In that case, erroneous operation can be prevented by making the user understand which state (mode) the user is in by displaying the "set temperature" and / or by using voice, light, or the like.

During the heat treatment (after the start of heating), the temperature rise rate detection process is performed (S6). This temperature rise rate detection process is a process in which heating is performed for a certain period of time (for example, a predetermined time between 10 seconds and 20 seconds) after the start of heating, then the heating is once turned off and then turned on after a predetermined time. In this case, heating for a certain period of time is set to a time at which the minimum amount of water is lower than the minimum set temperature, and when the amount of water is large, the time is set to heat higher than 1 degree. Is good. In this OFF / ON process, the water temperature that actually rises can be detected between OFF / ON, so that the temperature rise rate per unit time can be specified.

The ROM 82 of the control unit 80 stores a table regarding the temperature rise rate and a table regarding the heating time required to reach the target temperature for each amount of water, and by referring to the table regarding the temperature rise rate. , The amount of water in the container can be specified, and by referring to the table regarding the heating time, it is possible to specify how long it takes to reach the target temperature after turning it on again. It will be possible. Specifically, it is necessary from the actual amount of water in the container based on the rate of increase data of the current temperature (water temperature in the container) when a predetermined time elapses in the heating OFF state for several tens of seconds (for example, 30 seconds). (For example, if you know how many seconds it took for the temperature of the water in the container to rise once, you can heat it to the set temperature for how many seconds after turning it on. I know how).

In addition, in this temperature rise rate detection process, an abnormal heating detection process is also performed (S7). When there is no water in the container 10, the temperature rises rapidly (the temperature rise rate exceeds a specific value), so abnormal heating can be detected, and it is judged that there is no water, heating is stopped, and the temperature is displayed. An error is displayed on the unit 57 and the power is turned off (S7 → S7A). That is, even if the user makes an erroneous operation such as pressing the heating start key 55 without adding water, it is possible to reliably prevent waterless heating.

In the temperature rise rate detection process (S6), after the power is turned on without detecting abnormal heating, the target temperature heat process (S8) and the temperature control process (S9) are continuously executed.

In the above-mentioned target temperature heat treatment (S8), a predetermined heating time is determined based on the data obtained from the temperature rise rate obtained in S6, heating is performed for the determined time, and then heating is turned off. It becomes the set temperature. The timing for turning off the heating is set so that the temperature rise overshoots the target temperature, as will be described later. In this case, if the set temperature is not reached due to the influence of the external environment, the difference between the current temperature and the set temperature is specified when the current temperature stops rising, and the heating time according to the difference is specified. After heating for a predetermined time, the procedure for turning off the heating may be performed (this process may be repeated if necessary). Then, when the display of the current temperature reaches the set temperature, the fact that the set temperature has been reached is notified by sound or the like.

If the amount of water is the same, the lower the set temperature, the shorter the time it takes to reach the set temperature, and the rate of temperature rise becomes higher, making it easier to overshoot significantly than the set temperature (this). In this case, in temperature maintenance, it is necessary to wait until the temperature drops to the set temperature, and the lower the set temperature, the longer it takes). Therefore, in order to prevent a large overshoot and eventually reach the set temperature quickly, in the case of the same amount of water, the set temperature is lower than the temperature rise rate of the high set temperature (80 ° C, 90 ° C). By controlling the heating so as to reduce the temperature rise rate of (50 ° C., 60 ° C.), the set temperature can be reached in a short time as a result.

In S8 described above, after the target temperature heat treatment is completed (after overshooting with respect to the target temperature), the set temperature is within the control range (for example, the required accuracy range of ± 1 ° C. or ± 2 ° C.). The temperature control process is performed in (S9). As will be described later, this temperature maintenance management is performed by repeatedly turning the power on and off, and the temperature display unit 57 and the current temperature display unit 60 are always lit. At this stage, the control unit 80 is in a standby state for the timer to be activated (time start / stop key 56 is pressed) by the user (S10).

After the water in the containment section reaches the target temperature, the user can add tea leaves. As described above, the leaching time of tea leaves is an important factor in brewing delicious tea, and the tea leaves are put in with the time set by the user in (S5) displayed, and the time starts / When the stop key 56 is pressed, the timer 84 is activated, and the time display unit 58 displays a countdown or a countup (S10 → S11). The user can obtain the optimum component leaching state by taking out the tea leaves from the container containing the tea leaves with reference to the time displayed on the time display unit 58.

In this case, the displayed time or the time notified by the notification means is the optimum component leaching time for the user, but in the configuration of the teapot of the present invention, the tea leaves are used by the separation means (tea strainer 20). Can be separated from the container 10 at any time, so that the actual component leaching time can be adjusted. Further, since the state inside the container 10 (change in color of tea leaves) can be visually recognized at all times, such adjustment can be easily performed. That is, in the component leaching method of the present invention, the optimum component leaching temperature is obtained after the tea leaves are put into the accommodating portion while maintaining the set temperature of the water in the accommodating portion specified by the double water by the temperature control of the control unit 80. It is possible to grasp the actual component leaching time and adjust the component leaching time.

When the user presses the start / stop key 56 of the time while the predetermined time is actually displayed on the time display unit 58 (the time set by the user with the down key 54a and the up key 54b), the countdown is performed. The display is started (S11). Further, when the user presses the time start / stop key 56 while "0" is displayed on the time display unit 58, the count-up display is started (S11).

The countdown display, when the display becomes "0", performs notification processing by a notification means such as generating a sound together with the display, and notifies the user that the set component leaching time has been reached. Therefore, the component leaching time can be known even if the user is away. Further, after the time display unit 58 becomes "0" and a predetermined time elapses, the display returns to the same set time again, and when brewing at the same time next time, the time start operation (ON). All you have to do is (operate) (the next time you change the component leaching time, you can change it with the down key or up key).

Further, the count-up display (the first display is "0") displays the elapsed time until the user presses the start / stop key 56 of the time to stop the operation. In this count-up mode, the leaching time of the ingredients is displayed as a guide, and the user can see the leaching state (color change) of the tea leaves in the container and in a state preferable to the user, the tea leaves are separated by the separating means. It can be removed from the container compartment.
During the leaching of this component, it is preferable to use a tea strainer and a stirring rod to give the tea leaves (material) and water movement, and to separate the tea leaves and water.

Further, when it is detected that the user has lifted the container 10 from the base 50 during the time display, the power is turned off and the process ends (S12, S13). This is to prevent the container from being automatically turned on (the temperature is not controlled by the heating body 12) even if the container is returned to the base 50 again, which enhances the safety of the device.

Further, even if the container 10 is lifted from the base 50, it is preferable to continue the time display on the time display unit 58 and the notification by the notification means. That is, since it is possible that the user may remove the container 10 from the base 50 while the tea leaves are being brewed (during component leaching), it is preferable to inform the user of the component leaching time even in such a state. After the display process is started, it is preferable to continuously display the container 10 regardless of the state of the container 10 (the state of being placed on the base 50 or the state of being removed) as long as the user does not stop the time. ..

In the above processing process, the user can turn off the power switch 53 at any step. When the OFF operation is actually performed, the processing up to that point may be terminated at that point. In such a configuration, the user can also brew tea from a temperature lower than the set temperature.

According to the Kyusu that can perform the above processing procedure, it is used from the temperature setting change processing (S2) until the time display unit 58 displays the time (S11) or until the operation of S12 or S13 is performed. Since the person is not allowed to return to the previous step (temperature setting step) (one-way operation), erroneous operation and malfunction can be prevented, and even people who are unfamiliar with the machine can easily and surely enjoy delicious tea. You can brew. Further, since the operation of the time start / stop key 56 is performed independently of the heating operation, the heating time and the component leaching time can be grasped separately. Furthermore, when the same brewing method (same set temperature and time notification) is repeated using the above-mentioned Kyusu 1, the amount of water can be increased simply by performing the heating start operation (ON operation) and the time start operation (ON operation). Regardless of, you can easily brew tea with two operations. That is, since the control unit 80 controls to accept the operation for setting the temperature after the heating of the water is started, the temperature control step and the time control step are performed independently. As a result, erroneous operation can be reliably prevented, correct temperature control and time management become possible, and even delicate gyokuro and high-grade sencha can be brewed deliciously.

While the above processing procedure is being performed, removing the container 10 from the base 50 may be performed at any step. In this case, when the container 10 is removed from the base 50, the power may be turned off and the user may press the power switch key 53 again to return the power to the power ON state (when the power is turned off, the temperature sensor 25 may be returned. Is in a non-energized state, and the temperature display unit 57 does not display the temperature). Alternatively, when the container 10 is removed from the base 50 after S1 described above, when the container 10 is returned to the base 50 again, the processing after S2 is executed and the temperature is set without turning off the power. If the temperature is the same as the previous time, the heating may be started (ON operation) as it is. In this case, the heating temperature may not be controlled unless the user performs the heating start operation. This makes it possible to prevent the user from being heated without water, such as when the user pours tea into a hot water drink and there is no water in the container 10.

Further, when the detection temperature of the temperature sensor 25 exceeds 100 degrees (for example, it is detected that the temperature has reached 101 ° C.) in the heat treatment and temperature control processing states of S8 and S9, it is determined that the heating is waterless. It is preferable to turn off the power automatically. In addition, safety can be further improved by separately arranging a device for preventing dry cooking by using a thermostat or the like (preventing fire, etc., and allowing damage to the device).

According to the operation panel 51 operated when executing the above processing procedure, the set temperature, the current temperature, (heating state), the current temperature display, and the time notification can be visually recognized by the LED lamp and the digital display unit. It is possible to intuitively understand the operation state by visually observing what kind of state it is in. In particular, the temperature display unit 57 can more accurately grasp the component leaching of the tea leaf (material) by continuously displaying the current temperature during the component leaching time.

Note that another operation button (operation key) may be added to the operation panel 51 so that other operations can be performed. Further, some of the set temperature display unit 59, the current temperature display unit 60, the heating display unit 61, and the power lamp 62 arranged on the operation panel 51 may be omitted, and the temperature display unit 57 and the time display unit may be omitted. It may also be used as the display of 58. Further, the temperature and time setting change method may be set by one dial method instead of the down key and the up key which are used for both operations to simplify both operations, and the temperature display is in units of 1 ° C. It may be possible to set with.

In the above procedure, the temperature control method of S8 and S9 warms the water contained in the accommodating portion to accurately set the target temperature, and maintains the target temperature with high accuracy. In addition, the amount of water stored in the storage unit varies depending on the number of people who drink tea, and the heating time also varies accordingly. When the above-mentioned container 10 is placed on the base 50 at a predetermined position (predetermined position) and a heating instruction is given, the water in the accommodating portion is heated to a set temperature (target temperature) via the heating body 12. (Temperature control), temperature control is performed so as to maintain the temperature (temperature maintenance control).
Hereinafter, an example of the temperature control method will be specifically described.

FIG. 6 is a graph showing the time course of temperature when the water is heated by a constant heating power, with the heating time by the heating body 12 on the horizontal axis and the temperature detected by the temperature sensor 25 on the vertical axis. .. In this case, with 100 cc of water, the change with time of temperature has a steep gradient (large slope), whereas as the amount of water increases (200 cc to 500 cc), the change with time becomes gentle. Therefore, in the process of S6 of FIG. 5, it is possible to detect the amount of water in the accommodating portion by detecting the rate of increase in temperature per unit time (time-series data of water temperature).

For example, if a table of time-series data of the temperature of water when heated with a constant power is stored as control data of the ROM, the inside of the accommodating unit depends on the amount of change in the temperature detected from the temperature sensor and the time at that time. The amount of water can be specified. In addition, the control data shows the target temperature (in FIG. 6, the target temperature in FIG. 6) due to the residual heat (heat storage of the heater) when the heating is maintained for a few seconds and the heating energization is turned off from the amount of water and the current detected temperature. It is provided with a control table for reaching 70 ° C.). That is, the OFF line information (control table for specifying the OFF line) is stored for each target temperature, and the heating energization is controlled to be OFF when the temperature detected by the actual temperature sensor 25 reaches the OFF line. ..

The timing of turning off the heating energization is set so that the target temperature is overshooted by the residual heat after the heating energization is turned off (heating is turned off at a temperature obtained by subtracting the temperature rise due to the residual heat of the heating body 12). I am doing it). That is, after the heating by the heating body 12 starts, the control unit specifies the amount of water from the time-series data of the temperature of the water, and with the specified amount of water, how long should the heating be maintained? It is specified whether to overshoot the target temperature in consideration of the residual heat (the heating time is specified), and when that time is reached, the heating is controlled to be OFF.

In this case, the temperature rise due to the residual heat of the heating body 12 changes greatly when the amount of water changes significantly, and the temperature rise also changes accordingly. For example, if the amount of water is small, the temperature rise due to residual heat is large, and there is a possibility that the target temperature cannot be properly controlled. As described above, by adjusting the timing at which the heating is turned off according to the amount of water, the temperature rise due to the residual heat of the heating body 12 can be accurately controlled to the target temperature regardless of the amount of water. ..

In the above heating temperature control, data on the actual amount of water may be used for the amount of water in the accommodating portion. Regarding how to collect the data of the amount of water, for example, when setting the temperature, the user can input or select the amount of water from the operation panel, or a sensor for detecting the amount of water is arranged in the container body. Install and use the data obtained from this sensor, or place a weighing scale on the base, turn on the weighing scale when filling the container with water (zero setting), and inject water into the container. It is possible to use the data obtained by measuring the amount of water after that. If the data on the amount of water (the amount of water in the accommodating portion) is specified in advance, the heating energization may be controlled to be OFF when the temperature detected by the actual temperature sensor 25 reaches the OFF line.

As described above, the timing for turning off the heating is such that the maximum temperature is slightly higher than the target temperature (+ α ° C; overshoots with respect to the target temperature) in consideration of the temperature drop after reaching the target temperature. ) Is controlled. For example, in FIG. 6, when 300 cc of water (specified by the time series data of water temperature or the actual amount of water as described above) is warmed by setting 70 ° C. as the target temperature, it is heated. In consideration of the residual heat after the body is turned off, the OFF control is performed so that the maximum temperature is 70 ° C. + α ° C. This is in consideration of the fact that if the maximum temperature matches the target temperature, the actual temperature will fall below the target temperature immediately after the heating energization is turned off, and by the time the temperature maintenance control is started, This is to give a certain amount of time. In particular, when the tea strainer 20 is placed in the accommodating portion 10B, the temperature drops in a short time, so that it becomes easier to control the temperature to the target temperature as compared with the control that does not overshoot.

FIG. 7 is a flowchart showing an example of a control flow for executing temperature heating control (heating control) according to the control program of the control unit 80.
First, the control unit 80 acquires the target temperature set by the user (S21), heats it for a certain period of time from the start of heating, and then temporarily turns off the heating as shown in S6 of the control flow of FIG. 5 described above. A process of turning on after a predetermined time is performed. Since the water temperature that actually rises can be detected by the time of this OFF / ON process, it is possible to obtain the temperature rise rate per unit time, and the actual amount of water is specified (S22, S23). ..

As shown in FIG. 6, the OFF line control table specified in advance and the timing of heating / energizing OFF are set based on the current detection temperature (S24). Then, after the heating is turned on, when the OFF timing is reached, the heating energization is turned off and the control is terminated (S25, S26). By turning off the heating and energizing, the water in the accommodating part becomes a temperature slightly higher than the target temperature (target temperature + α ° C.) after a certain period of time after turning off, and this temperature is displayed on the temperature display unit 57. ..

In the above-mentioned heating control control, control when the amount of water in the container and the target temperature are different will be described with reference to the graph of FIG.
Here, a case where the amount of water is 150 ml and the target temperature is 60 ° C. (A), a case where the amount of water is 150 ml and the target temperature is 70 ° C. (B), and a case where the amount of water is 300 ml and the target temperature is 60 ° C. (C) will be described. .. In each case, the initial water temperature is 10 ° C.

As described in the control flow of FIG. 5, the temperature rise rate detection process is performed after a certain period of time has elapsed (15 seconds in the graph) after the heating is started by the heat treatment (indicated by ON (1)) operation. It is performed (S6 in FIG. 5). This temperature rise rate detection process is a process of temporarily turning off the heating (indicated by OFF (1)) and then turning it on after a predetermined time (in the graph, it is assumed that 30 seconds have passed) (indicated by ON (2)). ). There is almost no temperature change in the water temperature until the heating is turned off (1). In other words, the time until the first heating is turned off is set to a time at which almost no temperature change occurs regardless of the amount of water.

The rate of increase per unit time is detected by the time from OFF (1) to ON (2) (S6 in FIG. 5). The heat treatments of (A) and (B) have the same temperature rise rate because the amount of water is the same, and the heat treatment of (C) has a low temperature rise rate because the amount of water is large. Further, as shown in (D), when the temperature rise rate is extremely high in this range, it is regarded as empty heating and the heating is turned off.

As described above, the ROM 82 of the control unit 80 reaches the target temperature by the residual heat (heat storage of the heater) when the heating is maintained for a few seconds and the heating energization is turned off from the amount of water and the current detection temperature. It has a control table for reaching. That is, a control table for specifying the OFF line for each target temperature is provided, and the heating energization is controlled to be OFF when the temperature detected by the actual temperature sensor 25 reaches the OFF line. In this case, by adjusting the OFF timing (indicated by OFF (2)), the overshoot position (indicated by PA, PB, PC) is controlled to be substantially constant regardless of the amount of water and / or the target temperature. Therefore, it is possible to control the time from heating to reaching the target temperature substantially uniformly. Further, by setting the heating time to the target temperature to be long (heating little by little), the overshoot temperature can be reduced and the temperature can be maintained and managed accurately in a narrow range.

For the control of the heating temperature of water described above, the following method can be further used.
For example, when heating with the same amount of water, if the set temperature is low, the time to reach the target temperature is short, and if the set temperature is high, the time to reach the target temperature is long. Further, when heating at the same set temperature, when the amount of water is small, the time to reach the target temperature is short, and when the amount of water is large, the time to reach the target temperature is long. Therefore, the heating temperature control means heats and controls the heating body so that the temperature rise rate differs between the case where the set temperature is set low and the case where the set temperature is set high under the same water amount condition. Is preferable.

A specific description will be given with reference to FIG.
Consider the case where the target temperature is set to 80 ° C and the case where the target temperature is set to 60 ° C with the same amount of water. If the heating conditions for the heating body are the same, when the target temperature is 80 ° C., the time required to reach the target temperature is longer than when the target temperature is 60 ° C. Therefore, the heating body is controlled by heating so that the temperature rise rates of the two are different. Specifically, the temperature rise rate a1 when the target temperature is set to 80 ° C. (when set high) is the temperature rise rate when the target temperature is set to 60 ° C. (when set low). By controlling the heating body so that it is higher than a2, it is possible to brew tea in substantially the same time regardless of the set temperature.

Such variable control of the heating temperature is preferably performed after the water temperature reaches the initial heating temperature (a stable heating temperature, which is set to 30 ° C. in FIG. 9), and is the same until the initial heating temperature is reached. Heating is performed in the heated state of the above, and after reaching 30 ° C., heating is controlled so that the rate of increase differs according to the target temperature. The control table for this temperature rise rate is preset for each target temperature in the same amount of water, and is set so that the rise rate increases as the target temperature rises. In the example shown in FIG. 9, when the target temperature is 80 ° C., the temperature is controlled so as to heat at full power after 30 ° C. and turn off the power when the residual heat reaches 80 ° C. (may be overshooted). (The temperature rise rate is high), when the target temperature is 60 ° C, it is controlled to gradually heat from 40 ° C to 60 ° C (the temperature rise rate is low), and it is related to the target temperature for the user. It is controlled so that the difference in heating time does not cause a sense of discomfort.

According to such control of the heating temperature, it is possible to accurately control the set temperature even if the amount of water is small, and when approximately the same time elapses regardless of the amount of water or the set temperature. It is possible to brew tea. That is, the time to reach the target temperature is set to a relatively short time of about 1 minute to 2 minutes so that the operation can be performed with the same feeling.

At the same set temperature, the temperature rise rate when the amount of water is large may be set to be higher than the temperature rise rate when the amount of water is small. That is, the control table for the temperature rise rate is preset for each amount of water at the same set temperature, and the temperature rise rate when the amount of water is large is changed to the temperature rise rate when the amount of water is small. On the other hand, it may be set to be higher.

After the water reaches the set temperature (overshoot temperature) by the above-mentioned heat treatment, the temperature control control for maintaining the target temperature is performed.
In the example shown in FIG. 6, when the heating energization is turned off, the maximum temperature ((70 + α) ° C.) is reached after a certain period of time, and then the temperature drops, but the temperature drops by a constant temperature ((70-β) ° C.) from the target temperature. ), The heating and energization is controlled to be ON again for a certain period of time so that the temperature of water is returned to the maximum temperature ((70 + α) ° C.).

In this case, the amount of hot water may be used as it is, or a fixed amount may be used by pouring, but it is accommodated by detecting the rate of decrease in temperature per unit time (time series data of water temperature). Since it is possible to grasp the amount of hot water in the part, it is possible to control the ON time (timing from ON to OFF) from the time series data. It is also possible to use the data at the time of heating.

As a result, as shown in the graph of FIG. 5, the temperature can be maintained within a predetermined range (target temperature + α ° C. to target temperature −β ° C.) near the target temperature even after a lapse of time from the initial heating. The hot water in the accommodating part can maintain a substantially target temperature. For example, by setting α to 1 ° C or 2 ° C and β to -1 ° C or -2 ° C, the user always leaches the tea leaf extract with hot water (68 ° C to 72 ° C) near 70 ° C. Is possible. In particular, the range of temperature control is set to a set temperature of ± 2 ° C., preferably a set temperature of ± 1 ° C., so that tea can be brewed at a more optimum temperature.

With reference to FIG. 10, a control flow for executing temperature maintenance control (maintenance management) according to the control program of the control unit will be described. Here, it will be described that the maintenance of the temperature is performed in the range of (target temperature + α ° C.) to target temperature −β ° C.).
In the maintenance of the target temperature, the temperature of the hot water in the accommodating part is acquired by the temperature sensor 25 (S31), and when the temperature drops by a constant temperature (−β ° C.) (S32; Yes), the unit time up to that point is reached. Get the temperature drop rate. Since the current amount of water can be specified from this temperature decrease rate, the ON time of the heating energization until the temperature reaches (target temperature + α ° C.) is specified, and the heating energization is turned ON (S33, S34).

Then, by turning off the heating energization when the ON time of the heating energization elapses (S35, S36), the temperature of the hot water in the accommodating portion rises to the above-mentioned (target temperature + α ° C.) after a certain period of time. After that, it is determined whether or not temperature maintenance is necessary (S37), when temperature maintenance is necessary (S37; Yes), the same control is repeated again after returning to S31 described above, and temperature maintenance is not necessary (S37). S37; No), the target temperature maintenance control ends.
The case where the temperature maintenance is not required here means, for example, when a certain time has passed since the temperature maintenance was started, when all the hot water is poured out, or when the temperature detected by the temperature sensor 25 drops. For example, when the user turns off the power on the operation panel.

According to the teapot 1 as described above, after the water is stored in the container 10, the tea leaves can be added at the optimum temperature by a simple operation procedure (one-way operation that does not cause an operation error) and is appropriate. Since the leaching time is notified, anyone can brew delicious tea with the same feeling as a conventional pottery teapot without skill. Further, since the operation can be performed while looking at the operation panel 51 provided on the surface of the protruding flat portion 50B of the flat base 50, the operability is good and the leaching state of the tea leaves is also leached through the container. Since it can be visually recognized, it is possible to easily obtain a desired taste. That is, since the leaching state (color and turbidity) of the tea leaves can be visually recognized through the visual portion of the container 10, it is easy to intuitively grasp the astringent state (dark state) and the mild state (light state). Therefore, regardless of the set component leaching time, the component can be leached in the state desired by the user. When the tea leaves are visually recognized through the visual recognition unit, the temperature, the component leaching time, and the component leaching state can be visually recognized at the same time from the same direction, so that the temperature, time, and density can be grasped at the same time.

In addition, in the teapot 1 having the above configuration, the actual tea leaf component leaching time can be adjusted, and the user can brew delicious tea of the user's taste by controlling the component leaching time. be. That is, the component leaching time is an ideal value predetermined according to the double water, and it is easy to adjust to the optimum component leaching state while grasping this ideal value.

As shown in FIG. 2, in the teapot of the present embodiment, a tea strainer can be installed as a means for separating dried tea leaves and water. In this case, the double water (amount / ratio of water to the material) for obtaining a desired taste and the temperature of water associated therewith are heated and maintained by the above-mentioned control unit 80. The component leaching time (the actual component leaching time from when the material is put into the container until the water and the material are separated) is determined by the time management in the control unit 80 described above according to the double water and the tea leaves. can get.

As described above, in addition to the count-up display (count-down display), the change in color through the visual part of the container 10 can be grasped, so that the user controls the leaching time of the component. You will be able to easily brew tea with the optimum ingredient leaching condition that suits you.

The means for separating water and tea leaves is not limited to tea strainers, and can be appropriately modified by making it a tea bag type or a stirring rod type.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be variously modified.
The above-mentioned temperature heating control and temperature maintenance method are only shown as an example, and can be variously modified.
