Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toilet air conditioner in which a part of the refrigerant piping of a heat pump type refrigeration cycle is installed above the toilet seat and the toilet bowl to warm the top of the toilet seat or the toilet bowl to improve the convenience of urination. It is.

Most conventional toilet seats were heated using electric heaters, which resulted in high electricity bills. Some toilet seats are heated with hot water, but this also requires a separate water heater. Additionally, the entire toilet room was air-conditioned with a separate heater in the winter and an air conditioner in the summer. In addition, air conditioning was performed from a separate room using ducts, but efficiency decreased due to heat leakage. Therefore, there were many disadvantages such as high maintenance costs, limited installation space, replacement of air conditioners in winter and summer, and reduced efficiency due to heat leakage.

The object of the present invention is to heat a toilet seat using the heat of the refrigerant of the toilet air conditioner, and to provide a toilet air conditioner equipped with a cooling device and a heating device. Installed above the toilet seat and toilet bowl to warm the toilet seat. Another object of the present invention is to provide a toilet air conditioner for the energy-saving era, in which the entire toilet room is air-conditioned by the above-mentioned device.

The present invention will be explained below with reference to an embodiment shown in FIGS. 1 to 9.

The air conditioner body mounted on the inner box 2 is inserted inside the outer box 1, and the compressor 3,
outdoor heat exchanger 4, outdoor heat exchanger blower 5,
A blower motor 6 for the outdoor heat exchanger is attached, and an outdoor air intake duct 7 and an outdoor air discharge duct 8 are attached to the left and right sides of the bottom, and both ducts 7 and 8 protrude outside through the wall 9. Further, a shikiri plate 10 is installed on the upper part of the outdoor heat exchanger 4, and an indoor heat exchanger 11, an indoor heat exchanger blower 12, and an indoor heat exchanger blower motor 13 are installed thereon.
The outer box 1 is provided with an indoor air inlet 14 and an indoor air outlet 15, a top plate 16 is attached, and the air conditioner is installed on a toilet bowl 17 as a toilet air conditioner having an integrated structure of an indoor unit and an outdoor unit. Further, 18 is a toilet wash water tank, 19 is a toilet seat, 20 is a refrigerant pipe, 21 is a toilet lid, and 22 is an operation switch mounting plate.

In this configuration, during cooling operation, air sucked through the indoor air suction port 14 is heat-exchanged and cooled by the indoor heat exchanger 11, and then sent to the indoor air discharge port 1.
At the same time, outdoor air is sucked in from the cooling air suction duct 7 of the outdoor heat exchanger 4, and the hot air heat-exchanged in the outdoor heat exchanger 4 is discharged from the exhaust heat discharge duct 8 to the outdoors. A series of refrigeration cycles are then repeated to cool the toilet room and the toilet seat or bowl. In addition, the heating in the toilet room is performed at the indoor air intake port 14 in the above cycle.
The air sucked in is heat exchanged in the evaporator 11 to generate warm air, which is discharged from the indoor air outlet 15 to heat the toilet room. The refrigerant circulation in the heating/refrigeration cycle (FIG. 5) having the above configuration is carried out by the operation of the compressor 3, and the medium temperature refrigerant flows in the direction of the arrow of the four-way valve 23 and heat exchanged in the indoor heat exchanger 11.
Or, the refrigerant flows into the refrigerant pipe 20 installed at the top of the toilet bowl 17 and cools the toilet seat 19 or the toilet bowl 1.
The refrigerant heats the upper part of 7, passes through the capillary 24, becomes warmed in the outdoor heat exchanger 4, and cools the four-way valve 2.
It returns to the compressor 3 in the direction of the arrow 3 and repeats a series of heating and freezing cycles to warm the toilet seat 19 or the upper part of the toilet bowl 17. During cooling operation, the refrigeration cycle during heating operation is switched by the four-way valve 23 to perform a heat pump type refrigeration cycle (FIG. 6). The refrigerant, which has become high in temperature due to the operation of the compressor 3, flows in the direction of the arrow of the four-way valve 23 and passes through the outdoor heat exchanger 4.
The medium-temperature refrigerant that has undergone heat exchange flows through the capillary 24 into the refrigerant pipe 20 installed above the toilet seat 19 or the toilet bowl 17, cools the toilet seat 19 or the upper part of the toilet bowl 17, and then passes through the indoor heat exchanger 11. The heated refrigerant passes through the four-way valve 23 in the direction of the arrow and returns to the compressor 3, repeating a series of heat pump cycles to cool the toilet room and at the same time, the toilet seat 19,
Alternatively, the upper part of the toilet bowl 17 is cooled. FIG. 7 shows a cooling operation in which the refrigerant pipe 20 at the discharge port of the compressor 3 is installed above the toilet seat 19 or the toilet bowl 17, and the heated refrigerant exchanges heat to warm the top of the toilet seat 19 or the toilet bowl 17. It's a cycle. FIG. 8 also shows that the refrigerant pipe 20 at the discharge port of the compressor 3 is installed above the toilet seat 19 or toilet bowl 17, and the heated refrigerant is circulated in a heat pump cycle to perform heating operation. Warm the top of the.
Fig. 9 shows a heat pump type cycle in which during heating operation in winter, the top of the toilet seat 19 or toilet bowl 17 is heated, and the high temperature refrigerant closes the bypass solenoid valve 25 and opens the solenoid valve 26, which heats the top of the toilet seat 19 or toilet bowl 17. The refrigerant flows into the refrigerant pipe 20 above the toilet bowl 17, exchanges heat, and warms the above-mentioned equipment. In addition, during cooling operation in summer, the solenoid valve 26 is closed and the bypass solenoid valve 25 is opened, and the refrigerant that has undergone heat exchange in the evaporator 11 is returned to the four-way valve 23 and compressor 3 through the capillary 24 and condenser 4. Toilet seat 19 or toilet bowl 17 during summer cooling
An example of a refrigeration cycle that does not heat the upper part of the

As explained above, the outdoor unit and the indoor unit are integrated, and the toilet room is cooled and heated, and at the same time the toilet seat or the top of the toilet bowl is warmed, and the function as a toilet air conditioner is fully demonstrated and the effect is great.

As explained above, the present invention cools and heats the toilet room, and at the same time uses a heat pump type refrigeration cycle to heat the high temperature refrigerant through the refrigerant pipes installed on the toilet seat or the top of the toilet bowl, thereby warming the toilet seat and making it comfortable. This was designed to improve convenience.
Therefore, it is a compact toilet air conditioner that is less expensive to maintain than conventional electric types, has no restrictions on installation locations, and is highly effective.
