Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathroom heater / dryer capable of heating or drying a bathroom or a dressing room (hereinafter referred to as a bathroom) by four-way blowing.
[0002]
[Prior art]
The temperature of a bathroom in a general house does not change much from the outside air temperature when nobody has bathed yet, so for people who have reduced environmental adaptability, such as the elderly, sudden temperature changes in winter May cause a large heat shock, causing sudden blood pressure fluctuations and fatalities.
[0003]
On the other hand, due to changes in housing conditions in recent years, there is a case where ventilation of a bathroom or the like cannot be performed sufficiently, and mold is easily generated on the wall or ceiling of the bathroom or the like, and means for drying the bathroom or the like is desired.
[0004]
Furthermore, due to changes in housing conditions, it is often difficult to secure a clothes drying place for drying laundry, and it has been proposed to use a bathroom or the like as a clothes drying place.
[0005]
In response to such a demand, for example, a bathroom heating dryer as in JP-A-9-66199 has been proposed.
[0006]
As shown in FIGS. 18 and 19, the bathroom heater / dryer 10 according to the above publication circulates the heat exchanger 12 through which the hot water from the heat source unit 11 circulates and the air in the bathroom through the heat exchanger 12. A crossflow fan 13, a ventilation fan 14 for ventilating air in a bathroom, and the like, a power supply block 18 for supplying power to the crossflow fan 13 and the ventilation fan 14, and the like are provided.
[0007]
And the said bathroom heating dryer 10 is installed in the opening provided in ceilings, such as a bathroom, and becomes the structure by which the hot water piping 16 and the exhaust duct 15 were connected by the ceiling back.
[0008]
Installation and maintenance of the bathroom heater / dryer 10, hot water piping 16 and exhaust duct 15 and the like are carried out by reaching the back of the ceiling from the inspection port 17 provided adjacent to the opening, and sometimes entering the back of the ceiling. To do.
[0009]
In addition, a general room, not limited to a bathroom, has a ceiling formed by a decorative board supported by a field edge, etc., and a ceiling provided by it and supported by neda etc. (for example, a floor on the second floor) The space between them forms the back of the ceiling. Therefore, in this specification, the ceiling affixed with the decorative board is described as a bathroom ceiling, and the ceiling above the ceiling is described as a main ceiling.
[0010]
[Problems to be solved by the invention]
However, the bathroom heater / dryer 10 according to the above configuration has a problem in that since the warm air is blown out by the cross flow fan 13, the blowing direction is one-way blowing and a large temperature distribution is generated in the bathroom or the like.
[0011]
FIG. 20 shows the result of simulating the temperature distribution in the bathroom in the case of such one-way blowing. As can be seen from the figure, if the main space such as a bathroom is set around body temperature (36 degrees), the temperature in the vicinity of the outlet must be 40 degrees or more.
[0012]
This can prevent heat shock due to low bath temperature, but there is a risk of falling and falling due to heat shock due to high temperature.
[0013]
In addition, since the warm air does not hit the wall of the bathroom or the like, there is a problem that the drying efficiency is deteriorated when the bather touches the wall of the bathroom or the like to feel cold or the bathroom is dried.
[0014]
Furthermore, the bathrooms and the like of houses constructed in recent years have many standard dimensions (for example, 1 tsubos type), and the decorative panels used for bathroom ceilings and the like have many standard dimensions. Therefore, there is a problem that it is difficult to provide the bathroom heater / dryer 10 and the inspection port 17 in an optimal place.
[0015]
In other words, bathrooms are equipped with bathtubs, doors, windows, etc., and the temperature distribution depends on them, so when determining the location of the bathroom heating dryer, these positions and It is necessary to provide the optimal position in consideration of the size and the like.
[0016]
Such determination of the optimal position requires construction with the assumption of actual temperature distribution, and therefore, installation and construction work is essential for operators with such knowledge and experience. However, there is a problem that the construction cost becomes high.
[0017]
In addition, even if the optimum position is determined, if the optimum position is a corner of the bathroom ceiling or does not coincide with the position of the joint (medium) of the decorative board, it becomes unnatural (the design becomes worse). There is a problem that you have to choose between taking a picture or taking a form.
[0018]
In addition, the air in the bathroom or the like is forcedly circulated through the bathroom heater / dryer by the cross flow fan 13, but there is a problem that large noise is generated by the flowing air.
[0019]
Therefore, an object of the present invention is to provide a bathroom heater / dryer with low noise while enabling four-way blowing to efficiently heat and dry a bathroom or the like.
[0020]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is divided into a heating chamber in which a heating part and the like are accommodated by a partition plate and a control room in which a ventilation part and a control part are accommodated. The heat exchanger is arranged in the heating chamber in a generally “U” shape having three sides along the inner three side walls of the main body case, and heat water is exchanged between the hot water from the heat source unit and the air to form hot air. And a circulation fan, and the partition plate is formed so that a partial shape of the circulation fan facing the centrifugal fan is an arc shape matching the curvature of the centrifugal fan so as to partially surround the centrifugal fan. The warm air is circulated through the heat exchanger to circulate the air in the bathroom or dressing room, and blows out from the first to fourth outlets provided in the vicinity of the four sides. It is provided at two places on the heat exchanger corner on the circulation fan side in the exchanger. The upper end portion is bent to form a contact portion that contacts the heat exchanger via a heat exchanger seal material, and the lower end portion is formed with a fixing portion that is fixed to the main body case by a screw. A fixing member for supporting the corner portion of the heat exchanger and fixing the heat exchanger to the main body case is provided, and the fixing members at the two locations are erected in the direction of the circulation fan to increase the strength of the fixing member. And having ribs for suppressing air turbulence generated at the corners .
[0022]

FIG. 5 is a side view of the bathroom heater / dryer installed on the bathroom ceiling.
[0023]
The bathroom heater / dryer 100 includes a main body 101 that heats and ventilates the bathroom and the like by exchanging heat of the air in the bathroom and the like with hot water, a grill 102 that is installed on the front surface (side of the bathroom, etc.) of the main body 101, and the main body 101. Has an installation device 103 and the like.
[0024]
The installation device 103 includes a field edge fixture 105 that is fixed to the field edge 104 and the like, and a suspension member 106 that fixes the body 101 by hanging the body 101 from the field edge fixture 105.
[0025]
As shown in FIG. 6, the field edge fixing tool 105 has a square angle, and a female screw 107 is fixed to each corner portion. A plurality of through holes 109 are provided in the side plate 108, and the field edge 104 is screwed to the field edge 104. It is the composition to do.
[0026]
As shown in FIG. 7, the suspension member 106 includes a bolt 110 and a washer 111. The bolt 110 has a front end threaded portion 112 formed at the front end and a rear end threaded portion 113 formed at the rear end, and the diameter of the intermediate region 114 depends on the screw of the front end threaded portion 112 and the rear end threaded portion 113. It is appropriately smaller than the diameter formed by the valley.
[0027]
On the other hand, the washer 111 has a cut 116 formed up to the central hole 115. The dimension D1 of the central hole 115 is appropriately larger than the diameter D2 of the intermediate region 114 of the bolt 110 and smaller than the diameter D3 formed by the head of the bolt 110.
[0028]
As shown in FIG. 8, the grill 102 is provided with first to fourth louvers 244 to 247 so as to open and close the first to fourth outlets 240 to 243 at the periphery of the four sides. The blowing direction of warm air is set by 244 to 247.
[0029]
On the other hand, a generally “T” -shaped hinge claw 120 whose head is formed wider than the leg is protruded from one end of the intake panel 117, and an open / close button 121 is provided at the opposite end. . Further, filter support claws (not shown) are provided at opposite ends of the back surface (the main body 101 side) of the intake panel 117 so that the filter can be attached and detached.
[0030]
FIG. 9 is a perspective view showing an internal configuration of the main body 101. The main body 101 sucks air from a bathroom or the like, turns it into warm air, and then blows the air again into the bathroom or the like. The air guide part 161 for guiding the warm air to the four first to fourth outlets 240 to 243, the ventilation part 130 for ventilating the air etc. in the bathroom, the control part 131 for driving and controlling the heating part 128 and the ventilation part 130, etc. These are housed in the main body case 132.
[0031]
The main body case 132 is partitioned into a heating chamber in which the heating unit 128 and the like are accommodated by a partition plate 133 and a control room in which the ventilation unit 130 and the control unit 131 are accommodated. High humidity air is prevented from entering.
[0032]
As shown in FIG. 10, the heating unit 128 is formed in an approximately “U” shape having three sides, and heat-exchanges the air in the bathroom or the like with the hot water circulated from the heat source unit 136 through the hot water pipe 137. The heat exchanger 138 includes a circulation fan 139 that discharges air from the bathroom and circulates it through the heat exchanger 138.
[0033]
The heat exchanger 138 is disposed along the side wall of the main body case 132, and is fixed to the main body case 132 by a fixing member 141 via a heat exchanger seal material 140. Further, the water supply / drainage part 230 of the heat exchanger 138 extends to the control room side and is fixed to the side wall of the main body case 132.
[0034]
The heat exchanger 138 and the side wall of the main body case 132 are provided so as to face each other at a predetermined interval, and a buffer space 147 for the warm air from the heat exchanger 138 is formed. Hot air is blown out to the bathroom or the like through the fourth outlets 240 to 243.
[0035]
Accordingly, the warm air from the heat exchanger 138 flows through the buffer space 147 and is then blown out from the first to fourth outlets 240 to 243 smaller than the buffer space 147, so that the buffer space 147 acts as a silencer. As a result, the noise caused by blowing air can be reduced.
[0036]
In addition, the fixing member 141 is provided at two places on the heat exchanger corner 148 on the circulation fan 139 side in the heat exchanger 138, and the upper end portion thereof is bent as shown in FIG. A contact portion 142 that contacts the heat exchanger 138 via the material 140 is formed, and a fixing portion 143 that is fixed to the main body case 132 by a screw is formed at the lower end portion.
[0037]
Furthermore, the end portion of the main column portion of the fixing member 141 is bent at a predetermined angle to form a rib 150, thereby enhancing the strength of the fixing member 141 and reducing the noise by the following actions. Yes.
[0038]
In other words, the air discharged from the circulation fan 139 is blown in a direction depending on the angle of the impeller (described later), and thus has a component that rotates in the heating chamber. For example, in FIG. 9, the air rotates clockwise. For this reason, a turbulent flow is likely to occur in the heat exchanger corner portion 148 minutes, and noise increases.
[0039]
Such a turbulent flow cannot be physically prevented because the circulation fan 139 has a circular shape and the heat exchanger 138 has a rectangular shape. Therefore, noise due to the turbulent flow cannot be eliminated. .
[0040]
However, if this turbulent flow is made into a plurality of small turbulent flows, the overall noise can be reduced. That is, since the small turbulent flow has low energy, the noise due to each turbulent flow becomes small. And since the phase of the noise frequency by these several turbulent flows does not usually correspond, the component which cancels arises and it becomes possible to suppress noise as a whole.
[0041]
Therefore, the fixing member 141 is provided in the heat exchanger corner 148 on the circulation fan 139 side where a large turbulent flow is generated, and the rib 150 is erected on the main pillar portion in the direction of the circulation fan 139 to generate a large turbulent flow. The noise is suppressed by suppressing the generation.
[0042]
Of course, since the silencing effect varies depending on the shape of the rib 150 (extension length, angle, etc.), the wind speed of the circulation fan 139, etc., it goes without saying that it is necessary to design appropriately according to the situation.
[0043]
On the other hand, the circulation fan 139 includes a centrifugal fan 151 provided with a plurality of impellers, a circulation motor 152 that rotates the centrifugal fan 151, and a ventilation port that cools the circulation motor 152 by the intake air. The circulation motor cover 154 is provided on the top and bottom of the circulation motor 152 and is detachably provided on the main body case 132. By engaging the circulation motor cover 154 with the main body case 132, the circulation motor cover 154 is provided. A circulating motor support member 155 and the like that support the elastic member 152 with elastic force.
[0044]
Then, when the centrifugal fan 151 rotates, air in the bathroom or the like is sucked from the central portion of the centrifugal fan 151 and discharged to the outer periphery of the fan. At this time, since the discharge direction has no directivity, air is discharged isotropically.
[0045]
However, when air is discharged also to the control room side without the heat exchanger 138, the air hits the partition plate 133, changes the flow path, and flows into the heat exchanger 138. For this reason, noise caused by wind noise when air hits the partition plate 133 or turbulent flow generated when the flow path is changed becomes noise.
[0046]
Therefore, in the present invention, the shape of the part of the partition plate 133 facing the centrifugal fan 151 is formed in an arc shape according to the curvature of the centrifugal fan 151, and is arranged so as to partially surround the centrifugal fan 151. Has been established. As a result, air is not blown out from the part, so that the noise is reduced and the dead space of the heating chamber is reduced.
[0047]
In addition, since the dimension of the bathroom heating dryer 100 concerning this invention is set according to building standards, such as a bathroom, it is contrary to this meaning to make it small more than necessary. Therefore, the dead space of the heating chamber omitted by the partition plate 133 is not directly reflected in the downsizing of the apparatus, but is used for securing the peripheral space of the control unit 131.
[0048]
Since the peripheral space acts as a cooling space for the control unit 131, it is possible to efficiently cool it, and a work space for maintenance and inspection can be used, so that work efficiency can be increased.
[0049]
When the circulation motor 152 is attached, the circulation motor support member 155 is attached to the top and bottom of the circulation motor 152, and the engagement claw 156 of the circulation motor cover 154 is inserted into the insertion hole 159 and rotated.
[0050]
Thereby, the engaging claw 156 can be engaged with the insertion hole 159, and the circulation motor cover 154 can be temporarily fixed to the main body case 132. In addition, in the temporarily fixed state of the circulation motor cover 154, the positions of the through hole 157 and the screw hole are matched.
[0051]
Therefore, a screw is inserted from the through hole 157 to fix the circulation motor cover 154 to the main body case 132. At this time, since the circulation motor cover 154 is temporarily fixed, the operator can use both hands, and can use a screwdriver while holding down the screw. The screw and the circulation motor cover 154 are dropped during screwing. It is designed not to end up. Of course, the same effect can be obtained during maintenance inspection.
[0052]
As shown in FIGS. 12 to 15, the air guide portion 161 includes a heating chamber cover 126 provided with first to third blowing windows 162 to 164 to cover the heating chamber, and a fourth outlet 243. The fourth blowout window 165 is provided so as to match the position of the control chamber cover 127 that covers the control chamber, and the heating chamber and the control chamber are not communicated with each other, and the fourth blowout window 165 is communicated with the heating chamber. The wind guide 166 is configured.
[0053]
12 is a top view of the heating chamber cover 126, FIG. 13 is a side view when viewed from the arrow C in FIG. 12, FIG. 14 is a partial side view when viewed from the arrow E in FIG. FIG. 4 is a perspective view including a control room cover 127.
[0054]
The heating chamber cover 126 is provided at a peripheral portion in the direction of the intake windows 168 and 3 that forms a passage for the air that is sucked into the circulation blower 139 by opening the intake portion at a central portion appropriately smaller than the circulation blower 139. When assembled, they contact the first to third outlet windows 162 to 164 and the heat exchanger seal member 140 whose positions coincide with the first to third outlets 240, 241, and 242 provided on the grill 102. Partition ribs 169 that divide the heating chamber into the circulation fan 139 side and the buffer space 147 side, and a branching rib 171 that is formed of a mountain-shaped protrusion provided at a corner portion of the buffer space 147.
[0055]
The air blown out from the circulation fan 139 is divided into left and right at the corner portion of the buffer space 147 and blown out from the adjacent outlets. At this time, turbulence is likely to occur at the corner portion. Therefore, the diverting rib 171 is designed to reduce noise by smoothly diverting the air blown from the heat exchanger 138 so that no turbulent flow is generated in the corner portion.
[0056]
As shown in FIG. 15, the control room cover 127 is provided with a fourth blowout window 165 so as to coincide with the position of the fourth blowout outlet 243, and for ventilation of air sucked into a ventilation blower 173 described later. An air passage 174 and a ventilation inlet 175 are formed, and a hot air guide 166 is fixed to the back surface of the control chamber cover 127.
[0057]
The hot air guide 166 is a box body in which one of the side walls is opened to form the hot air introduction port 176 and the upper surface is opened, and is fixed to the back surface of the control chamber cover 127 where the fourth blowing window 165 is located, Hot air introduced from the hot air inlet 176 is blown out from the fourth outlet 243 through the opening on the upper surface.
[0058]
Next, the installation procedure and the maintenance inspection procedure of the bathroom heating dryer 100 having the above-described configuration are installed in the bathroom and the dressing room shown in FIG. 4, and the hot water from the heat source 136 is used for drying the bathroom heating in the dressing room. The case where it is supplied to the machine 100 will be described as an example.
[0059]
Moreover, the installation of the bathroom heater / dryer 100 will be described in the case where it is installed in an existing house, and the distance between the edge 104 of the bathroom ceiling and the dressing room ceiling is 60 cm. However, it is obvious that the present invention is not limited to these and may be installed in a new house.
[0060]
It is assumed that a decorative ceiling board is fixed to the field edge 104, and the position of the edge of the decorative ceiling board is the position of the field edge 104.
[0061]
The installation procedure and the maintenance / inspection procedure will be described based on such premise, but the installation procedure and the like common to the bathroom heating dryer 100 in the bathroom and the dressing room will be described without distinguishing between them.
[0062]
First, the installation opening 212 for installing the bathroom heating dryer 100 is provided in the bathroom ceiling or the like. The size of the main body case 132 of the bathroom heater / dryer 100 is, for example, 53 cm, and the installation opening 212 is, for example, a 55 cm square. The size of the grill 102 is wider than the interval between the field edges 104, for example, 61 cm.
[0063]
Since the minimum width between the field edges 104 in the standard house is 60 cm, any standard house can be installed if the dimensions are set as described above, and the work between the field edges 104 can be expanded. The cost associated with it becomes unnecessary.
[0064]
The hot water pipe 137 from the heat source machine 136 is piped to the bathroom heating dryer 100 in the dressing room. At this time, the hot water pipe 137 is appropriately long for the reason described later. Further, the ventilation duct 216 is disposed up to the vicinity of the installation opening 212. Further, a control line 213 is wired.
[0065]
Next, the field edge fixture 105 is fixed to the field edge 104. Then, the screw thread 112 of the bolt 110 is screwed into the female screw 107 of the field edge fixture 105 so that the bolt 110 is suspended from the installation opening 212.
[0066]
After such a state is completed, as shown in FIG. 16, the main body 101 of the bathroom heating / drying machine 100 is lifted, and the bolts 110 are passed through the suspension holes 177 provided at the four corners of the periphery of the main body 101. The hanging hole 177 is appropriately larger than the head of the bolt 110 and smaller than the washer 111.
[0067]
Then, the washer 111 is inserted into the bolt 110 from the notch 116, and the main body 101 is lowered by bringing the washer 111 into contact with the head of the bolt 110. Since the suspension hole 177 is smaller than the washer 111, the main body 101 comes into contact with the washer 111 and is in a suspended state. FIG. 17 is a cross-sectional view showing the situation at this time.
[0068]
After the bathroom heater / dryer 100 in the bathroom and the dressing room is in such a suspended state, the hot water pipe 137 and the control line 213 are connected.
[0069]
Since the hot water pipe 137 is made of a moderately flexible resin pipe or the like and is long, the end of the hot water pipe 137 is drawn out to the bathroom side and connected to the water supply / drainage section 230.
[0070]
Thereby, the connection of the hot water pipe 137 and the control line 213 is completed, and then the main body 101 is fixed at a predetermined position. The main body 101 is fixed by rotating the front end threaded portion 112 of the bolt 110 until it exceeds the female screw 107 so that the female screw 107 is positioned in the intermediate region 114. Therefore, the main body 101 and the bolt 110 are pushed up, and the rear end screw portion 113 and the female screw 107 are screwed together.
[0071]
After the body 101 is fixed in position, remove the control chamber cover 127 (which may be previously removed), connected from the inside of the body case 132 a ventilation duct 216 so as to pull on the body case 132.
[0072]
Then, the grill 102 is screwed to the main body 101, and the angle of the four first to fourth louvers 244 to 247 is adjusted so that the hot air is blown in a desired direction as appropriate, thereby installing the bathroom heating dryer 100. Is completed.
[0073]
Depending on the state of the installation device 103, the formation state of the installation opening 212, the fixed state of the decorative ceiling panel, etc., the main body 101 may not be parallel to the media of the decorative ceiling panel. At this time, since the end of the main body case 132 and the medium are close to each other, they are conspicuous even in a slightly non-parallel state, and fine adjustment is necessary.
[0074]
However, since the size of the grill 102 according to the present invention is set to be larger than that of the decorative ceiling board, the medium of the ceiling decorative board is hidden and can be made inconspicuous even in some non-parallel state. ing.
[0075]
When the maintenance check of the bathroom heater / dryer 100 installed in this way is performed, it is possible to go back to the installation procedure described above.
[0076]
