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 blowing in four directions.
[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 with 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, and a means for drying the bathroom 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. 25 and 26, 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. It has a cross flow fan 13, a ventilation fan 14 for ventilating air in the bathroom, a power supply block 18 for supplying power to the cross flow fan 13 and the ventilation fan 14, and the like.
[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. 27 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 maintenance and inspection, for example, when replacing the power supply block 18 or the motor, the engaging portion must be released using a flat-blade screwdriver, which complicates the configuration and makes the workability worse. There is a risk of dropping the block 18 or the motor.
[0019]
Therefore, the present invention enables four-way blowing to efficiently heat and dry a bathroom, etc., and allows easy installation and maintenance without using an inspection port. An object of the present invention is to provide a bathroom heater / dryer in which the removed electrical parts are not dropped.
[0020]

The anti-extraction protrusion 205 is a mountain-shaped protrusion provided at the end of the electrical component support member 203, and the top of the projection 205 is when the electrical component support member 203 is correctly stored in the control unit case 202. The electrical component support member 203 is prevented from falling out of the control unit case 202 by being inserted into the anti-extraction protrusion engaging hole 207.
[0054]
When the electrical component support member 203 is pulled out from the control unit case 202, the open end 209 of the pull-out preventing projection 205 is pulled inward of the case, and the engagement between the pull-out preventing projection 205 and the pull-out preventing projection engaging hole 207 is engaged. This is done by releasing the match.
[0055]
During maintenance inspection of the control unit 131 (the bathroom heater / dryer 100 is installed on the ceiling of the bathroom), if the engagement between the anti-extraction protrusion 205 and the anti-extraction protrusion engagement hole 207 is inadvertently released, The electrical component support member 203 may fall and be damaged.
[0056]
In order to prevent such a situation, the fall prevention claw 206 is provided so as to engage with the fall prevention claw lock 208 when the electrical component support member 203 is pulled out to a predetermined position.

Therefore, when the electrical component support member 203 is housed, the fall prevention claw 206 is positioned in the arcuate portion 210 and does not contact the control unit case 202, but when dropped, the fall prevention claw 206 is moved to the arcuate end. It is inserted into the portion 211 to prevent further dropping.
[0059]
Of course, since there is a possibility of inspection or replacement of electrical components, at that time, the electrical component support member 203 is pulled out until just before the drop prevention claw 206 is locked to the arc-shaped end portion 211, and then from the arc-shaped end portion 211. The lower main body case 132 may be appropriately widened and pulled out so that the fall-preventing claw 206 is not locked to the arcuate end 211.
[0060]
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.
[0061]
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.
[0062]
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.
[0063]
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.
[0064]
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 distance between the field edges 104, for example, 61 cm.
[0065]
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.
[0066]
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.
[0067]
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.

After such a state is completed, as shown in FIG. 23, 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 around the main body 101. The hanging hole 177 is appropriately larger than the head of the bolt 110 and smaller than the washer 111.
[0069]
Then, the washer 111 is inserted into the bolt 110 through 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. 24 is a cross-sectional view showing the state at this time.
[0070]
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.
[0071]
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.
[0072]
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.
[0073]
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.
[0074]
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.
[0075]
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.
[0076]
However, since the size of the grill 102 according to the present invention is set to be larger than that of the decorative ceiling plate, the medium of the decorative ceiling plate is hidden so that it can be made inconspicuous even in some non-parallel state. ing.
[0077]
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.
[0078]
