Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toilet air conditioner using a refrigeration cycle, and particularly to an exhaust heat treatment method for the air conditioner.

[Conventional technology]

Conventionally known toilet air conditioners using a refrigeration cycle are equipped with a ventilation duct from the outside to the condenser to radiate the heat generated in the condenser of the air conditioner to the outside air, and draw in outside air to cool the condenser. The heat was radiated to the outside air, or the condenser was installed in a part facing the outside air, and the outside air was sucked in through the intake and exhaust ports provided on the outer wall of the room, and the heat from the condenser was radiated to the outside air.

[Invention tries to solve it! ia]

However, with the above exhaust heat treatment method, the former requires duct construction to provide an intake and exhaust passage for outside air, which increases the cost of installation work, while the latter requires installing the air conditioner in the part facing the outside air. Since this requires installation, there is a problem in that it cannot be installed in a toilet that is installed in a place that does not face the outside air.

The present invention has been made in view of the above-mentioned circumstances, and provides an air conditioning system for a toilet that does not require construction of ducts to communicate with the outside air, and can be easily installed even in toilets located in locations that do not face the outside air. The purpose is to provide the following.

[Means for Solving the Problems] In order to achieve the above objects, the present invention provides (1) a toilet equipped with a refrigeration cycle in which a refrigerant compressor, a condenser, an fJIi pressure device, and an evaporator are sequentially connected; In the air conditioner, the low tank stores water to be flushed into a toilet bowl installed in a toilet, a storage chamber housing the condenser, and a storage chamber communicating with the low tank to store the condensate in the storage chamber. (2) a first drainage channel for draining water supplied to the condenser into the low tank; A first solenoid valve that opens and closes a drainage channel, a second drainage channel that drains water supplied to the condenser to an overflow pipe in the low tank, and a second solenoid valve that opens and closes this second drainage channel. and a temperature sensor that detects the temperature of the water supplied to the 'a condenser; if the detected temperature of the temperature sensor is below the set temperature,
The first solenoid valve is opened and the second solenoid valve is closed.
control to drain water from the drain channel to the low tank, and if the temperature is higher than a set temperature, close the first solenoid valve and open a second solenoid valve to drain water from the second drain channel to the overflow pipe in the low tank. It is desirable to have the means and the following in order to exert the cooling ability.

[Effect]

According to the above means, (13) Since the water in the low tank of the toilet is supplied to the condenser and returns to the low tank, the heat generated in the condenser is radiated to the supplied water, so It becomes unnecessary to radiate heat to the outside air.

(2) Also, if the temperature of the water supplied to the condenser in the low tank is below the set temperature, the water supplied to the condenser will be drained to the low tank through the first drainage channel and returned to the low tank. When the temperature exceeds the set temperature, the water supplied to the condenser is drained through the second drainage channel to the overflow pipe of the low tank and flows into the toilet bowl, which lowers the water level in the low tank and prevents the well-known float water supply. The mechanism operates and cold water is supplied into the low tank, so the condenser is always cooled with water below the set temperature.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention shown in the drawings will be described.

FIG. 1 is a sectional view showing an embodiment of the toilet air conditioner of the present invention, and FIG. 2 is a perspective view showing the external appearance of the same device.

In Figures 1 and 2, an air conditioner (air conditioner) 20
is installed separately from a Western-style toilet bowl 1 having a low tank 3. At the top of the air conditioner 20, an air passage is provided which has a suction port 20a for sucking in air from inside the toilet, and a blowout port 20b for blowing the sucked air back into the toilet. A filter 28 is installed.

The main elements of the refrigeration cycle of the air conditioner 20 are arranged at the bottom of the air passage, and this refrigeration cycle includes a drive motor 2.
A refrigerant compressor 21 with 1a. Condenser 22. Decompression device 2
3. It is composed of an evaporator 24 and an accumulator 25. Here, the evaporator 24 is installed upstream of the blower 26. The m condenser 22 is installed in a water tank 22b that accommodates the condenser 22, which is provided in a water passage that takes in and discharges water from the low tank 3.

A water supply device is installed in the low tank 3 for supplying and stopping water from a general household water pipe. The water supply device includes a floating ball 9 that detects the water level in the low tank 3. It consists of a pole tap 5b that controls water supply and water stoppage from the water supply pipe 5a into the low tank 3 depending on the position of the floating ball 9, and an overflow vibrator 10 to prevent water from overflowing from the low tank 3. Furthermore, inside the low tank 3,
The Western-style toilet 1 is a device consisting of a water stop valve 8 having a floating rubber 8a, a manually rotated drain valve 6, and a chain 7 connecting the water stop valve 8 and the drain valve 6. ．． It is equipped with a rim water passage 12 provided around the upper part of the toilet bowl part 11 and a trap part 15 at the lower part of the toilet bowl part 11, and the water drained from the drain port 4 of the low tank 3 passes through the drainage passage 4a. The water flows into the toilet bowl part 11 and is drained from the trap l5 through the drainage passage 16 and from the drainage vibrator l7 at the bottom of the floor 40.

A control unit 50, which is integrated with a valve seat 13 and a toilet lid 14, is installed on the top of the toilet bowl 1 and performs hot water flushing.

Each toilet function is controlled by an operation panel 51 for operating shower/toilet functions such as drying, drainage function, and air conditioner function.

In addition, a temperature sensor (not shown) installed in the toilet room
Upon receiving the signal, according to instructions from the control unit 50,
The room is cooled or heated.

A temperature sensor 30 for detecting water temperature is provided in the water tank 22b in the air conditioner 20, and as shown in the control block diagram of FIG. 3, a comparison section 50a compares the temperature detected by the temperature sensor 30 with a set value. When the detected temperature is higher than the set value, the second solenoid valve 29b is opened and the first solenoid valve 29a is closed, and when the detected temperature is lower than the set value, the second solenoid valve 29b is closed and the first solenoid valve is closed. A control section 50b that controls opening 29a is incorporated in the control unit 50.

Water for cooling the condenser 22 is sucked in by a water pump 27 installed downstream of the water tank 22b in the air conditioner 20, and is pumped into the first and second downstream of the water pump 27.
Solenoid valve 29a. The water is returned into the low tank 3 through the first and second drainage channels 31 and 32, which are switched by 29b.

A water intake port 33 for sucking water in the low tank 3 is installed at the bottom of the low tank 3 and has a built-in filter for removing dirt and the like from the water. The water sucked in from here passes through a metal U-shaped pipe 34a inserted between the low tank 3 and the lid 2 of the low tank 3, and passes through the water intake port 33 and the U-shaped pipe 34a.
The double tube 34a, the water intake port 33.

The U-shaped pipe 34a2 enters the water tank 22b through a suction channel 34 made of a flexible pipe that connects the water tank 22b (indicated by → in FIG. 1).

The water that has absorbed heat from the condenser 22 is branched into two directions downstream of the water pump 27 so that the water is discharged into the low tank 3 at different locations depending on the water temperature detected by the water temperature sensor 30.

The first drainage channel 31 includes a first solenoid valve 29a and a U-shaped pipe 31a.
, consists of a flexible pipe that connects them, and is installed so that it can be discharged to the water surface of the low tank 3. The circulation waterway between the low tank 3 and the condenser 22 is composed of the water suction pipe 34, 34a and the drainage channel 31 as described above. The second drainage channel 32 is composed of a second electromagnetic valve 29b, a U-shaped pipe 32a, and a flexible pipe connecting them, and is provided so that water is discharged into the overflow pipe 10 in the low tank 3.

Further, a flexible pipe 36 for directly guiding water to the water intake port 33 is connected to the water supply pipe 5C for supplying water for draining waste into the low tank 3.
The end portion is fixed by a stopper 35 in the section.

Next, the operation of the above embodiment will be explained based on FIGS. 1 and 2.

When the temperature in the toilet room exceeds the cooling set temperature, the drive motor 21a is energized by an instruction from the control unit 50, and the rotation of the drive motor 21a causes the compressor 21
is driven to rotate. Therefore, a high-temperature, high-pressure gas refrigerant is sent from the compressor 21 to the condenser 22, where it is condensed and liquefied, and then depressurized and expanded in a decompression device 23, such as a capillary, to become a mist of refrigerant and enter the evaporator 24. The atomized refrigerant that has entered the evaporator 24 takes heat from the surroundings when it evaporates, but is exchanged with the air sucked in from the suction port 20a of the air conditioner 20 by the blower 26 provided downstream of the evaporator 24. Since the cool air is blown into the toilet room from the outlet 20b, the inside of the toilet is cooled. The refrigerant evaporated in the evaporator 24 passes through an accumulator 25 from which gas refrigerant is extracted.
The cycle back to the compressor 21 (indicated by the arrow in FIG. 1) is repeated.

Here, the heat generated when the refrigerant is condensed and liquefied in the condenser 22 is absorbed into the low tank 3 by the water pump 27.
Heat is radiated to the water inside. When the water temperature detected by the water temperature sensor 30 is below the set value, the first solenoid valve 29a is opened and the second solenoid valve 29b is closed, so that the high temperature is transferred from the first drainage channel 31 to the vicinity of the water surface in the low tank 3. The resulting water is released (indicated by → in Figure 1). The high-temperature water is discharged near the water surface, and since the high-temperature water has a small specific gravity and accumulates near the water surface, water at an initial low temperature can be continued to be sucked from the water suction port 33 at the bottom of the low tank 3.

When the low temperature water at the bottom of the low tank 3 runs out over a long period of operation, the water metal body inside the low tank 3 becomes high temperature, and the water temperature detected by the water temperature sensor 30 exceeds the set value, the first solenoid valve 29a By closing the second solenoid valve 29b and opening the second solenoid valve 29b, high-temperature water is discharged from the second drainage channel 32 into the overflow pipe IO. The discharged water passes through the toilet bowl 1 and is thrown away from the drain 17 (indicated by → in Figure 2).
.

FIG. 4 is a flowchart showing the above-mentioned drainage control. In step 101, the temperature of the water in the low tank 3 supplied to the condenser 22 is determined. If the temperature is higher than the set value, the process moves to step 102 and the first Close the second solenoid valve 29a and open the second solenoid valve 29b to drain the water supplied to the condenser 22 to the overflow pipe lO. If the water is below the set value, step 1
03, the first solenoid valve 29a is opened and the second solenoid valve 2 is opened.
9b is closed and the water supplied to the condenser 22 is transferred to the low tank 3.
Controls the drainage to. In addition, when water is discharged to the overflow pipe 10 in the step 102, the water is discharged to the toilet bowl 1 and the water level in the low tank 3 is lowered, so the position of the floating ball 9 is lowered, and as a result, the water supply valve in the ball tap 5b is is opened, and water is supplied from the water supply pipe 5a to the low tank 3 through the water supply port 5C. Since this water is guided directly to the water intake port 33 by the flexible hose 36, the air conditioner 20 can once again exchange heat with low-temperature water.

As described above, by separating the water intake port 33 in the low tank 3 and the drain port of the first drain channel 31 vertically, it is possible to prevent the initial low temperature water from mixing with the water that has become high temperature due to heat exchange and increasing the temperature. Become. Therefore, initial low-temperature water is supplied to the air conditioner 20 for a long time, and a decrease in cooling capacity can be minimized.

Even if the low-temperature water runs out and all the water becomes high-temperature, the water supply pipe 5a
, 5c is directly introduced into the water intake port 33 without mixing with the high-temperature water in the low tank 3, and for the same reason, the reduction in cooling capacity is minimized. In an ordinary household, 1
I use the toilet several thousand times a day and drain it each time, so 1
The inside of the low tank 3 is always filled with low temperature water after each use.

Therefore, since heat is dissipated into the water that was originally meant to be thrown away, the water supply does not increase the cost of tap water, but with this system, it is necessary even if the toilet does not drain for a long time (such as when the toilet is not used for a long time). It is possible to provide an air conditioner for a toilet that uses a minimum amount of water and does not reduce its cooling capacity.

In addition, this system can be installed in all low tanks such as general Western-style toilets, and by adjusting the length of the water absorption and drainage channels, the air conditioner can be installed in any part of the toilet.

Needless to say, no exhaust work is required because the waste heat is disposed of into water.

In addition, the high temperature of the wastewater makes it difficult for dirt to adhere to the inside of the toilet bowl.
Furthermore, the temperature of the toilet bowl also rises during the summer.

It can also prevent the problem of dew condensation on the toilet bowl surface during the rainy season.

Next, in this embodiment, the air conditioner 20 is separate from the toilet bowl 1, but the air conditioner 20 and the toilet bowl 1 may be integrated via the low tank 3.

In this embodiment, the condenser 22 is provided in the water tank 22b, but a normal water-cooled heat exchanger in which the function of the water tank 22b is incorporated into the condenser 22 may also be used. .

In addition, in this embodiment, the air conditioner 20 is exemplified as Tala, but when used for heating, the air outlet 20b of the air conditioner 20
An electric heater may be installed near the evaporator 24 to operate only the blower 26, or the flow of the refrigerant may be switched to operate the evaporator 24.
It is also possible to use a heat pump type that works as a condenser and radiates heat.

Note that the toilet air conditioner of the present invention can of course be applied to Japanese-style toilets as long as the low tank 3 is installed.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

(1) By dissipating the heat from the condenser into the water in the low tank, there is no need to dissipate the heat to the outside air, so there is no need for ductwork to introduce outside air from outside the toilet, and the location does not face outside air. Air conditioning equipment can be easily installed even in toilets located in public areas.

Furthermore, since the temperature of the water flowing into the toilet bowl is high due to the heat dissipation of the condenser, there are also effects of improving the cleaning performance of the toilet bowl and preventing dew condensation on the toilet bowl.

(2) Since the water in the low tank that cools the condenser is always replaced with cold water below the set temperature, the condenser is effectively cooled and the cooling capacity of the air conditioner is always utilized.
