BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner of a flush toilet apparatus in which an air conditioner for cooling or heating a toilet room or the like is provided in a flush toilet that flushes and flushes water in a toilet bowl, and a flush toilet apparatus using the air conditioner.
[0002]
[Prior art]
The air conditioner provided in the conventional flush toilet apparatus has a configuration as shown in FIG. That is, the air conditioner having the compressor 31, the condenser 32, the evaporator 33, and the like constituting the refrigeration cycle is provided with the condenser 32 on the wall across the corner of the toilet room 34, and stores water for washing the toilet 35. The compressor 31, the evaporator 33, the blower fan 37, etc. are placed in one case 38 and installed on the wall of the toilet room 34.
[0003]
Then, the refrigerant is circulated with the condenser 32, the evaporator 33, and the compressor 31 by the operation of the compressor 31, and the air in the toilet room 34 is heat-exchanged by the evaporator 33 by the blower fan 37, and the toilet room 34 is discharged from the outlet 39. The cooling air is sent to the air-conditioner, and the condensation heat of the condenser 32 is radiated to the water in the water tank 36 and is not released into the toilet room 34.
[0004]
The water tank 36 is provided with an electromagnetic valve 41 in a passage 40 for guiding the hot water heated by the condensation heat to the toilet bowl 35, and the electromagnetic wave is detected based on a detection signal of a temperature detector 42 for detecting the water temperature of the water tank 36. It was the structure which controls the opening / closing frequency of the valve 41 more or less. In the figure, 43 is a toilet seat.
[0005]
[Problems to be solved by the invention]
In the conventional toilet air conditioner, since the condenser 32 is submerged in the water tank 36, maintenance becomes difficult, and the compressor 31, the evaporator 33, the blower fan 37, etc. are provided in the case 38. Since the condenser 32 is separately attached to the water tank 36 on the wall, the entire apparatus is not organized, and the installation work in the toilet room 34 is troublesome, and the effective space of the toilet room 34 is further reduced.
[0006]
During the air conditioning operation, the water in the water tank 36 is heated by condensation heat until the electromagnetic valve 41 is opened based on the detection signal from the temperature detector 42 and flows out to the toilet 35 through the passage 40. As a result, the temperature rises relatively quickly, and an upper and lower temperature distribution is generated in the water tank 36. The heat radiation action of the condenser 32 is reduced in a short time, and the cooling capacity may be lowered. The water inside was drained through the passage 40, which was uneconomical. Furthermore, since the solenoid valve 41 opens and flows based on the signal from the temperature detector 42 that detects an increase in the water temperature of the water tank 36 regardless of the intention of the user of the toilet, the drainage is unexpectedly generated in the toilet. Sometimes it can be uncomfortable.
[0007]

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an air conditioner for a flush toilet apparatus according to the present invention and a flush toilet apparatus equipped with the apparatus will be described with reference to the drawings.
[0017]
(Embodiment 1)
FIG. 1 is a block diagram showing the air-conditioning apparatus for a flush toilet apparatus according to an embodiment of the present invention and the front main part of the flush toilet apparatus provided with the air-conditioning apparatus, and FIG. 2 is a schematic perspective view thereof. The air conditioner that cools the toilet room 1 has a compressor 2, a condenser 3, a decompressor 4, an evaporator 5 of a finned tube heat exchanger, etc. that constitute the refrigeration cycle, and further circulates the air in the toilet room 1. A control unit 7 mainly composed of a blower fan 6 that exchanges heat with the evaporator 5 and a microcomputer that controls the cooling operation by wiring to the blower fan 6 and the compressor 2 is added.
[0018]
Such an air conditioner supplies water such as a drainage channel 11 and a water pipe connected to a vertically long and thin flat water tank 10 (low tank) that stores flush water flowing in the toilet 8 and washing it up to a full water surface 9. A water supply pipe 12 connected to a water source, and is disposed outside the water tank 10 that exchanges heat with the condenser 3 by washing water that flows in from the water supply pipe 12 and flows into the water tank 10 from the drainage channel 11. The exchanging means 13, the compressor 2, the condenser 3, the evaporator 5, the blower fan 6, etc. are placed beside the outer surface of the water tank 10, and the substrate of the control means 7 is brought close to the lower front surface of the water tank 10. The water tank 10 and the air-conditioning device, which are arranged in an organically combined compact manner, are covered with a single flat-type case 14, and are further provided upright integrally with the rear portion of the toilet seat 15 provided in the toilet bowl 8. Attach to the rear end of toilet 8 That.
[0019]
The condenser 3 and the heat exchanging means 13 are a double pipe heat exchanger having a high heat exchange rate and capable of being miniaturized, or a flow path through which washing water flows between the plate members by laminating a plurality of plate members. A plate laminated heat exchanger having a flow path through which the refrigerant of the refrigeration cycle is formed is used. In this example, a double pipe heat exchanger comprising an outer pipe 13a through which water passes and an inner pipe 3a through which the refrigerant of the refrigeration cycle passes is used. I am using it.
[0020]
The water supply pipe 12 is provided with a flow rate adjusting means 16, which is opened slightly during operation of the air conditioner to allow a small amount of washing water to flow into the water tank 10 through the heat exchange means 13 and the drainage channel 11. Is a small amount of water that can sufficiently dissipate the heat of condensation generated when the condenser 3 performs a condensing action that can exhibit the cooling capacity of the air conditioner, and is reused by returning to the small amount of water and the water tank 10. It will also save water.
[0021]
That is, in the flow rate adjusting means 16, the flow of a small amount of washing water flowing from the water supply pipe 12 through the heat exchange means 13 to the water tank 10 from the water supply pipe 12 through the heat exchange means 13 at the time of operation of the air conditioner is simply configured by the water pressure of the water supply source. In addition, the condenser 3 exchanges heat with water at a new low temperature and stable temperature where the water in the heat exchanging means 13 for exchanging the heat always replaces, and condenses by efficiently performing the heat radiation action of the condenser 3. Heating by the heat of the vessel 3 prevents the water from rising in temperature and reducing the cooling capacity.
[0022]
Of course, the flow rate adjusting means 16 is closed when the air conditioner is not operated to save water, and is opened to the maximum when the toilet 8 is washed, and the water tank is passed through the water supply pipe 12, the heat exchanging means 13 and the drainage channel 11. 10 is supplied, and the cleaning water used for cleaning the toilet 8 and discharging the filth is replenished in a short time. The flow rate adjusting means 16 adjusts the flow rate and adjusts the amount of wash water flowing to the water tank 10 through the heat exchange means 13, that is, further adjusts the flow rate of a small amount of wash water that can exhibit the capacity of the condenser. Even when the temperature setting for air conditioning of the apparatus is changed to high or low, the heat exchange means 13 can be adapted to the heat radiation change of the condenser 3 by adjusting the flow rate of the small amount of washing water.
[0023]
Thus, the flow rate adjusting means 16 for opening and closing and adjusting the flow rate is controlled by the control means 7, and when the operation operation of the air conditioner is performed, the control means 7 can receive the signal and exhibit the cooling capability of the air conditioner. The flow rate adjusting means 16 is executed by a program to control the degree of opening so that a small amount of water that can sufficiently dissipate the heat of condensation generated when the condenser 3 performs the condensing action.
[0024]
Further, when the control means 7 receives the operation signal at the time of cleaning the toilet bowl, the control means 7 interrupts the instruction for controlling the flow rate adjusting means 16 to the degree of opening of the small amount of water by the operation of the air conditioner previously received, and gives priority to this. The flow rate adjusting means 16 is executed by executing a stored program so that the opening degree can be maximized. Further, the control means 7 receives the operation signal of high and low temperature setting for air conditioning of the air conditioner, and executes the stored program so that the flow rate adjustment corresponding to this is performed, and the opening degree is determined. Is to control.
[0025]
In the water tank 10, a large amount of washing water is passed from the water tank 10 to the toilet bowl 8 at a time to discharge filth after the stool and wash the toilet bowl 8. 18 is provided. The water stop means 17 is opened and closed by control of the control means 7 based on an operation signal at the time of toilet flushing by the user, and the flow rate adjusting means 16 and the control means 7 receiving the operation signal at the time of operation of the air conditioner. The same opening degree is controlled, and the same amount of small amount of water that flows into the water tank 10 through the water supply pipe 12, the heat exchange means 13, and the drainage channel 11 flows from the water tank 10 to the toilet 8.
[0026]
The local cleaning device 19 includes a local cleaning nozzle 20 that injects hot water to the local part, a pump 21 that sends hot water for cleaning to the local cleaning nozzle 20, and an electric that warms the cleaning water that is ejected from the local cleaning nozzle 20 by the pump 21. And the like, and is arranged in a horizontally long manner integrally with the toilet seat 15 at the lower front portion of the case 14. Of course, the case 14 may be covered together with the air conditioner, the water tank 10 and the like.
[0027]
For example, reference numeral 23 denotes an intake port provided at the lower side of the case 14, and reference numeral 24 denotes outlets provided at the left and right ends of the upper part of the front surface of the case 14. I'm trying to put it out. Further, a deodorizing device (not shown) is added at the optimum position of the flow path from the intake port 23 to the blowout port 24. A valve seat cover 25 is provided on the toilet seat 15 so as to be freely opened and closed. The toilet seat 15 is provided with a heater for heating. Reference numeral 26 denotes a blower guide of the blower fan 6, which leads to the outlet 24. A pipe 27 communicates with the water pipe and is connected to the hot water tank of the local cleaning device 19. The arrows in the figure indicate the flows of air, water, and refrigerant in the refrigeration cycle.
[0028]
In the above embodiment, when the air conditioner is operated with a switch or the like before or after entering the toilet room 1, the control means 7 starts control. That is, the refrigerant circulates in the order of the compressor 2, the condenser 3, the decompressor 4, the evaporator 5, and the compressor 2, and the flow rate adjusting means 16 and the water stopping means are received by the control means 7 that receives the instruction signal for operating the air conditioner. 17 is slightly opened, and tap water is adjusted by the flow rate adjusting means 16 from the water supply pipe 12 by the supply water pressure and flows into the heat exchanging means 13, and a small amount flows into the water tank 10 through the drainage channel 11. On the other hand, the same amount of the small amount of water that flows into the water tank 10 flows from the water tank 10 through the water stop means 17 to the toilet 8 from the drainage channel 18.
[0029]
As a result, the water is directly adjusted into the heat exchanging means 13 from the water supply pipe 12 by the flow rate adjusting means 16, and the condenser 3 has a new stable temperature with a low temperature at which the water in the heat exchanging means 13 is always replaced. By exchanging heat with water, the heat dissipating action of the condenser 3 can be efficiently performed, and it is possible to prevent the cooling capacity from being lowered due to the temperature rise of the water due to the heat of the condenser 3. On the other hand, the air in the toilet room 1 is sucked into the case 14 from the air inlet 23 by the rotation of the blower fan 6, passes through the deodorizing device, is deodorized, is cooled by the evaporator 5, and cool air is blown from the outlet 24. Blow out and air-condition the vicinity of the user's neck and toilet room 1 in the toilet seated on the toilet seat 15. Of course, if the air conditioning is unnecessary, the switch is operated to stop the operation of the air conditioner by the control means 7, and the flow rate adjusting means 16 of the water supply pipe 12 and the water stop means 17 of the drainage passage 18 of the water tank 10 are closed. Is.
[0030]
After the stool, the operation of the local cleaning device 19 is operated with a switch and controlled by the control means 7 to inject hot water from the local cleaning nozzle 20 to clean the local area. Thereafter, when the operation of discharging the filth and washing the toilet bowl 8 is performed with a switch or the like, the control means 7 having received this instruction signal gives priority to the signal for washing the toilet bowl in preference to the previously received operation instruction signal for the air conditioner. In response, the water stopping means 17 of the water tank 10 and the flow rate adjusting means 16 of the water supply pipe 12 are largely opened. Then, a large amount of washing water flows from the water tank 10 through the drainage channel 18 to the toilet bowl 8 at a time, and the filth is discharged, so that the toilet bowl 8 is washed. On the other hand, when a large amount of washing water has finished flowing from the water tank 10 to the toilet bowl 8, the water tank 10 having the full water surface 9 lowered to a predetermined position is supplied to the water supply pipe 12, the heat exchange means 13, New water is replenished from the water pipe through the drainage channel 11 to the full water surface 9 to stop water supply. Thereafter, the above operation is repeated, and the condenser 3 radiates heat to the water passing through the heat exchanging means 13 in large quantities. . When the toilet flushing is completed in this way, the control means 7 returns to the operation state of the original air conditioner again and controls the opening degree of the flow rate adjusting means 16 of the water supply pipe 12 and the water stop means 17 of the water tank 10. To do.
[0031]
As described above, in this embodiment, a small amount of washing water always flows to the water tank 10 through the heat exchange means 13 and the drainage channel 11 through the water supply pipe 12 slightly opened in the flow rate adjustment means 16 during operation of the air conditioner. Therefore, new low-temperature water flowing directly into the heat exchanging means 13 directly from the water supply pipe 12 is always replaced, and the condenser 3 can actively exchange heat, thereby preventing a reduction in the capacity of the air conditioner and reducing water consumption by a small amount. It can also be used for makeup water in the water tank 10.
[0032]
Further, since the condenser 3 is in a relationship of exchanging heat with the heat exchanging means 13 outside the water tank 10 , maintenance is easier than a configuration in which the condenser is submerged in the water tank, and heat exchange is performed at the supply water pressure. Heat exchange can be obtained with a simple configuration in which water flows into the water tank 10 from the means 13.
[0033]
The air conditioner and the heat exchanging means 13 are arranged on the outer side of the water tank 10, the control means 7 is arranged close to the front surface of the water tank 10, and these organic tanks are arranged in combination. Each component of the air conditioner is covered with one flat case 14 so as to be integrally provided upright at the rear part of the toilet seat 15 and attached to the rear end part of the toilet bowl 8, so that the entire apparatus can be made compact. At the same time, the effective space of the toilet room 1 can be secured, and the installation work at the site including the power supply and piping, that is, the toilet room 1 where it is generally difficult to secure a large space can be made much easier than the conventional one. To do.
[0034]
In the present embodiment, water is supplied to the heat exchanging means 13 through the flow rate adjusting means 16 during the operation of the air conditioner and during the cleaning of the toilet bowl 8, so that the heat exchanging means 13 is used not only during the operation of the air conditioner but also during the cleaning of the toilet bowl. Since the washing water is exchanged inside, the toilet washing water is added in addition to the original washing water, which can be used for the more stable heat exchange of the condenser 3 and the makeup water of the water tank 10.
[0035]
In this embodiment, since the water is supplied to the heat exchanging means 13 via the flow rate adjusting means 16, the amount of the washing water flowing to the water tank 10 through the heat exchanging means 13 is adjusted by the flow rate adjusting means 16, that is, a condenser. 3. Adjusting the flow rate of a small amount of washing water capable of demonstrating the capability of 3, and adjusting the flow rate of the small amount of washing water to cope with the heat dissipation change of the condenser 3 even when the air conditioning temperature setting is changed to high and low Temperature control can be facilitated.
[0036]
In the present embodiment, the flow rate adjusting means 16 is opened to the maximum when the toilet 8 is washed, and water is supplied to the water tank 10 through the water supply pipe 12, the heat exchange means 13, and the drainage channel 11, so that a large amount of water is reduced. The water tank 10 can be replenished in time.
[0037]
In the present embodiment, the heat exchanging means 13 and the condenser 3 can be constituted by a double tube heat exchanger composed of an inner tube 3a and an outer tube 13a , or a plate laminated heat exchanger. Compactness can be achieved by heat exchange and miniaturization.
[0038]

A detailed description will be omitted with reference numerals attached, and different points will be mainly described.
[0039]
The direct water supply path 28 is branched from the water supply pipe 12 upstream of the flow rate adjusting means 16, and is opened by the float 29 when the water level drops to a predetermined position from the full water surface 9 on the way. Automatic water supply for supplying cleaning water to the water tank 10. A valve 30 is provided.
[0040]
In the said embodiment, the operation | movement and effect by use of the operation | movement of an air conditioner, a stop, and the local washing | cleaning apparatus 19 are as having demonstrated in Embodiment 1. FIG. When the user discharges the filth and cleans the toilet bowl 8 after the stool, the control means 7 that receives this operation signal opens the water stop means 17, and a large amount of wash water from the water tank 10 enters the drainage channel 18. The filth is discharged and the toilet 8 is washed. On the other hand, the automatic water supply valve 30 is opened in the water tank 10 whose water level has dropped from the full water surface 9 and water is replenished from the direct water supply path 28 to the full water surface.
