Then, utilize Fig. 5, the control method of switching temperature in the refrigerator of the present embodiment is described.In addition, Fig. 5 is the controlling party block diagram of the control method of refrigerator for illustration of the present embodiment.
In Figure 5, the control device 46 be made up of such as microcomputer etc., the temperature that the temperature sensor 42 of temperature by detecting refrigerating chamber 2 is detected and by be set with storeroom and refrigerating chamber 2, refrigerating chamber 3, refrigerating chamber 4, vegetable compartment 5 the temperature that sets of the temperature regulation section 44 of temperature as input, based on these temperature, export control signal to retaining device 41 and heater 43.In addition, seal storage room 24 can between ice temperature temperature band and refrigerated storage temperature band switching temperature.
Due to as mentioned above, control device 46 is made up of microcomputer, so the various controls that temperature controls the light emitting control of (control of baffle controls, heater, compressor control etc.) and light emitting diode etc. are by being stored in built-in nonvolatile memory, such as, program in flash memory performs.
Specifically, when the detected temperatures utilizing temperature sensor 42 to detect is lower than certain fiducial temperature A, control (suppression) air conditioning quantity by the aperture or complete closing baffle plate device 41 reducing retaining device 41.In addition, when temperature drops to too low, be energized to heater 43, carry out the control making temperature increase.
On the contrary, when the detected temperatures utilizing temperature sensor 42 to detect is higher than fiducial temperature A, by increasing the aperture of retaining device 41, to the cold air free air space cool-air feed in seal storage room 24, carry out the control of the temperature reduced in seal storage room 24.
In addition, in the present embodiment, can be set in temperature adjustment part 44 " automatic mode " that automatically carry out between ice temperature temperature band and refrigerated storage temperature band switching, the switching of the storage temperature band of food decides based on the electric output of carbon dioxide sensor 45.
Such as, do not thrown light on by light emitting diode 46, under the state that photochemical catalyst does not play catalyst function, when being placed in seal storage room 24 by vegetables, within the stipulated time specified in advance, the gas concentration lwevel in seal storage room 24 is made to increase by the respiration of vegetables.In this condition, by making negative pressure pump 29 action (ON) be introduced in storage box by the air in seal storage room 24, and diffusion around carbon dioxide sensor 45, the electric output of carbon dioxide sensor 45 is declined.On the other hand, due to when saving meat and/or fish, there is no the respiration as vegetables, so gas concentration lwevel does not at the appointed time change substantially, therefore, electrically exporting and there is no much changes.Now, because catalyst function is inoperative, so do not change into carbon dioxide from the organic gas of meat and/or fish and foul smell composition.
By utilizing this characteristic, can distinguish the attribute of food, such as differentiation meat and/or fish and vegetables.Namely, carry out following control: under not carrying out the state of throwing light on by light emitting diode 46, when the electric output of carbon dioxide sensor 45 declines, what be judged as preservation is vegetables, switch to refrigerated storage temperature band, when electrically output does not have much changes, what be judged as preservation is meat and/or fish, automatically switches to ice temperature temperature band.Thereby, it is possible to be set in " automatic mode " that automatically carry out between ice temperature temperature band and refrigerated storage temperature band switching.
Then, after the judgement terminating food, start to be energized to light emitting diode 46, activate the photochemical catalyst be coated on surface plate 52.As mentioned above, if owing to putting into food, then produce carbon dioxide because of the deodorization of photochemical catalyst, so the gas concentration lwevel in seal storage room 24 rises.As long as keep the state being in sealing in seal storage room 24 just to continue to be energized to light emitting diode 46.
When being in long-time air-tight state constantly in seal storage room 24, the pressure increase caused in order to the small leakage of modifying factor closed container, regularly makes negative pressure pump action (ON), reduces pressure in closed container.Now, if owing to putting into food, then by the effect of photochemical catalyst, the organic gas produced by food is become carbon dioxide with foul smell conversion thus, so the gas concentration lwevel in closed container rises, if introduced by the gas in closed container in storage box, then the electric output of carbon dioxide sensor declines.In this case, owing to the organic gas from meat and/or fish being become carbon dioxide with foul smell conversion by photochemical catalyst, so the concentration of carbon dioxide has the trend along with the time increases.
But, owing to there is no accommodating food in seal storage room 24, natively there is not organic gas and/or foul smell composition, even if so by light emitting diode 46 exciting light catalyst, gas concentration lwevel also can not change, the state that the electric output of carbon dioxide sensor remains unchanged.
By utilizing above-mentioned characteristic, can distinguish and whether be placed with food (such as meat and/or fish, vegetables etc.) in seal storage room 24.That is, following control is carried out: when the electric output of carbon dioxide sensor 45 declines, being judged as being equipped with food in storeroom 24, by continuing to be energized to light emitting diode 46, making the deodorization continuous and effective of photochemical catalyst.
On the other hand, carry out following control: when the electric output of carbon dioxide sensor 45 does not change, be judged as there is no accommodating food, by stopping being energized to light emitting diode 46, make the catalyst function of photochemical catalyst invalid, thus suppress power consumption.
At this, the present embodiment carries out the light emitting control of light emitting diode 46 by carbon dioxide sensor 45, but as long as the catalyst function of exciting light catalyst can be carried out or make the judgement that the catalyst function of photochemical catalyst is invalid, can not be carbon dioxide sensor 45.
Then, utilize Fig. 6 and Fig. 7 for the change being detected the gas concentration lwevel in seal storage room 24 by carbon dioxide sensor 45, and then the method controlling light emitting diode 46 is described.In addition, the program being flash memories by being stored in microcomputer based on the negative pressure pump 29 of the action timing diagram shown in Fig. 7 and the control of light emitting diode 46 performs.
As shown in Figure 6, carbon dioxide sensor 45 generates the module of the semiconductor-type carbon dioxide sensor of the electric output of 0 ~ 5V for the concentration (ppm) that have employed the carbon dioxide according to surrounding, gas concentration lwevel such as in seal storage room 24 is Cx(ppm), from carbon dioxide sensor 45 output voltage Vx(V).Control device 46, according to the value of this voltage Vx, detects the gas concentration lwevel in seal storage room 24, the control of trip temperature of going forward side by side control and/or light emitting diode 46.
The carbon dioxide etc. that the carbon dioxide originally comprised in an atmosphere, carbon dioxide that food produces and the expiration of people to suck when accommodating food comprise is mixed in seal storage room 24.Therefore, by means of only mensuration voltage Vx, the carbon dioxide that food can not be produced or the carbon dioxide increased because of the catalyst action of photochemical catalyst branch away and detect.
Be described by the method for the action timing diagram shown in Fig. 7 to the producing cause distinguishing above-mentioned carbon dioxide.
First, as shown in Figure 7 (a), when refrigerating-chamber door 6 is "Off" → "ON" → "Off", the possibility being judged as food accommodating, as shown in Figure 7 (b) shows, while refrigerating-chamber door 6 becomes "Off", or after the stipulated time, only drive the negative pressure pump 29 action Ta time.Now, as shown in Fig. 7 (c), owing to stopping driving light emitting diode 46, so photochemical catalyst is in the state stopping its catalyst function.
As shown in Fig. 7 (d), the air be drawn in closed container by negative pressure pump 29 in this condition mixes the carbon dioxide in the expiration of air and people, and the concentration of carbon dioxide is Ca(ppm).
Therefore, as shown in Fig. 7 (e), because gas concentration lwevel is not very high, so driving the minimum of a value of the voltage utilizing carbon dioxide sensor 45 to detect in during negative pressure pump 29 to be Va.(along with negative pressure pump 29 action, the gas concentration lwevel flowing to carbon dioxide sensor 45 uprises, and therefore utilizes the voltage step-down that carbon dioxide sensor 45 detects.) gas concentration lwevel Ca in the seal storage room 24 that now detects mixes the carbon dioxide comprised in the carbon dioxide comprised in an atmosphere as above, the expiration people that flows into when accommodating food etc.Thus, be initial state by the ambient As in seal storage room 24, using the benchmark of carbon dioxide now as judgement below.
After this, as shown in Figure 7 (b) shows, after the stand-by time being spaced T1 time (such as dozens of minutes), again drive negative pressure pump 29 and only drive the Tb time, the minimum of a value of the voltage in during driving this negative pressure pump 29 is Vb.(along with negative pressure pump 29 action, the gas concentration lwevel flowing to carbon dioxide sensor 45 uprises, and therefore utilizes the voltage step-down that carbon dioxide sensor 45 detects.) owing to now also stopping driving light emitting diode 46, so photochemical catalyst is in the state stopping its catalyst function.
At this, when being placed in seal storage room 24 by vegetables, in during the T1 time, the gas concentration lwevel of closed container inside is made to increase by the respiration of vegetables.On the other hand, when preserving meat or fish etc. and not producing the food of carbon dioxide, gas concentration lwevel does not change substantially.This is because even if create foul smell composition or organic gas, the catalyst function of photochemical catalyst is still in the state of stopping.Gas concentration lwevel in seal storage room 24 now rises to Cb(ppm as illustrated in Fig. 7 (d)).
Therefore, inner at control device 46, when Vb=Va, can judge (deduction) as accommodating be meat or fish, can when Va > Vb, judge (deduction) as accommodating be vegetables.
In addition, the gas concentration lwevel sent from food represents with Va-Vb, and the value of Va-Vb is larger, then the climbing of gas concentration lwevel is higher.That is, more vegetables can be judged as accommodating.
At this, the driving time of negative pressure pump 29 and the pass of Ta time and Tb time are the Ta time < Tb time.This is because, the time (Ta time) of initial driving negative pressure pump 29 is after refrigerating-chamber door 6 has carried out the action of "Off" → "ON" → "Off", so the air pressure in seal storage room 24 uprises, when next driving negative pressure pump 29 (Tb time), the air in seal storage room 24 is reduced pressure.That is, the difference of the air capacity flowing to carbon dioxide sensor 45 is created due to the height according to this air pressure, so make the Tb time elongated to improve accuracy of detection.
Then, as shown in Figure 7 (b) shows, the negative pressure pump 29 action Tb time is only made, after this, as shown in Fig. 7 (c), while stopping negative pressure pump 29, or after the stipulated time, start to be energized to light emitting diode 46, to photochemical catalyst supply luminous energy, thus activated catalyst function.In this condition, by the catalyst function of photochemical catalyst, the organic gas sent from vegetables, meat, fish etc. is become carbon dioxide with foul smell conversion.Gas concentration lwevel in seal storage room 24 now rises to Cc(ppm as illustrated in Fig. 7 (d)).
After this, as shown in Figure 7 (b) shows, interval T 2 time (several hours), again drive negative pressure pump 29 and only drive the Tc time, as shown in Fig. 7 (e), the minimum of a value of the voltage in during driving this negative pressure pump 29 is Vc.(along with negative pressure pump 29 action, the gas concentration lwevel flowing to carbon dioxide sensor 45 uprises, and therefore utilizes the voltage step-down that carbon dioxide sensor 45 detects.）
At this, when food is placed in seal storage room 24, the catalyst function of exciting light catalyst is carried out by irradiating the light sent from light emitting diode 46, the gas concentration lwevel of the inside of seal storage room 24 is made to increase, on the contrary, when not having accommodating food, gas concentration lwevel is substantially constant.That is, inner at control device 46, when Vc=Vb, can be judged as there is no accommodating food, when Vb > Vc, the food being equipped with vegetables, meat, fish etc. can be judged as.In addition, the state representation of Fig. 7 is equipped with food, therefore continues to be energized to light emitting diode 46.
Therefore, when being judged as being equipped with food, continuing to be energized to light emitting diode 46, to photochemical catalyst supply luminous energy, when being judged as there is no accommodating food, stopping being energized to light emitting diode 46, thus stopping providing luminous energy to photochemical catalyst.
In the above described manner, by under the state of not exciting light catalyst, before and after interval T 1 time, drive negative pressure pump 29 twice, can judge that (deduction) be which kind of food creates carbon dioxide based on gas concentration lwevel change now.
In addition, by under the state of exciting light catalyst, interval T 2 time drives negative pressure pump 29 again, can detect the carbon dioxide whether having and increase because of the catalyst function of photochemical catalyst based on the change in concentration of carbon dioxide now, thus judges in storeroom 24 with or without food.Then, if be judged as there is no food in storeroom 24, then stop being energized to light emitting diode 46, thus the catalyst function of photochemical catalyst can be made invalid, suppress power consumption.
In addition, in the present embodiment, if be judged as there is no food in storeroom 24, then stop being energized to light emitting diode 46, but do not stop energising, but reduce the generation of luminous energy by reducing turn on angle, also can suppress power consumption.
In addition, in the present embodiment, by interval T 2 time, negative pressure pump 29 is driven between Tb time and Tc time, judge with or without food in seal storage room 24, but be not limited to this, the action that can also add negative pressure pump 29 further judges in seal storage room 24 with or without food.
(embodiment two)
Then, utilize Fig. 8 to be described the second embodiment of the present invention, the part repeated due to Fig. 8 and Fig. 7 is a lot, so be not described the part repeated.
The semiconductor-type carbon dioxide sensor 45 that the refrigerator illustrated in the above embodiments one uses has following characteristic: according to the temperature around sensor or humidity, the sensitivity of sensor changes, and its electric output also changes.
Therefore, if as shown in Figure 7, if temperature or humidity change, even if then gas concentration lwevel increases, sometimes also can obtain the result of primary measured value Va close to secondary measured value Vb, detect that gas concentration lwevel does not rise mistakenly.
At this, even if be described the method for the gas concentration lwevel that also can measure exactly in seal storage room 24 when there occurs change for temperature around or humidity.At this, in fig. 8, the switch of refrigerating chamber door, the action of negative pressure pump 29, the "on" position of light emitting diode 46 etc. are identical with Fig. 7.
First, as shown in Figure 8 (a), the driving time of negative pressure pump 29 and during the Ta time in, measure the maximum Vamax of electric output and the minimum of a value Vamin of carbon dioxide sensor 45.And then, the variation delta Va=(Vamax-Vamin electrically exported is tried to achieve according to this measured value).
The variation delta Va of the electric output of carbon dioxide sensor 45 is now regarded as the detected value of the gas concentration lwevel based on temperature, humidity within the Ta time.
Similarly, maximum Vbmax, Vcmax and minimum of a value Vbmin, the Vcmin of the electric output of the carbon dioxide sensor 45 in during Tb time and Tc time is detected.And then, the variation delta Vb=(Vbmax-Vbmin electrically exported is tried to achieve according to this measured value).Further, the variation delta Vc=(Vcmax-Vcmin electrically exported is tried to achieve according to this measured value).
Respectively the variation delta Vb of electric output now and variation delta Vc is regarded as the detected value of the gas concentration lwevel based on temperature, humidity within Tb time and Tc time.
At this, because Δ Va, Δ Vb, Δ Vc are the measured value measured under respective mensuration environment respectively, so eliminate Yin Wendu, the impact of humidity and the change of the electric output caused, obtain the change of the electric output of the increase and decrease based on gas concentration lwevel.
Therefore, when Δ Va=Δ Vb, can be judged as in seal storage room 24, preserving meat or fish or not preserving any food, when Δ Vb > Δ Va, can be judged as that gas concentration lwevel within the T1 time in seal storage room 24 rises, accommodating vegetables.In addition, when Δ Vb=Δ Vc, can be judged as there is no accommodating food in seal storage indoor, when Δ Vc > Δ Vb, can be judged as in seal storage room 24, being equipped with food within the T2 time.
In addition, Δ Vb=Δ Vc with must be equal to condition, be namely judged as roughly equal situation as long as also comprise in the scope of the amplitude of regulation.
By above-mentioned assay method, the accuracy of detection of carbon dioxide sensor 45 can be improved further.
In addition, in the present embodiment of the first embodiment and the second embodiment, the refrigerator arranging photochemical catalyst and light emitting diode is illustrated, but the present invention is not limited thereto, the refrigerator illustrated in the prior art can also be applied in seal storage room.In a word, the present invention can be applied to the refrigerator of device with the exciting light catalyst that undertaken throwing light on by lighting unit.
