Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a toilet device,
In particular, the present invention relates to a toilet device including a cooling unit.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open No. 63-1903.
No. 73, JP-A-2000-79077, etc., the toilet device is provided with a cooling means using a refrigerating cycle, and the washing water in the water tank is used as the cooling means for the condenser, and the cooling means is used. It is disclosed that the tank is integrated in a tank cover.

On the other hand, Japanese Patent Laid-Open No. 1-281340 discloses an air conditioner for a toilet, which controls the on / off timing of a blower during cooling and heating to prevent discomfort caused by blowing air. It is disclosed. Specifically, during cooling, even if the cooling means is stopped, airflow is continued to eliminate the discomfort caused by the stoppage of airflow, and during heating, when the heating means is stopped, the airflow is stopped and the discomfort caused by blowing cold air is eliminated. Is disclosed.

[0004]

In the toilet device, an AC power supply of 100V AC is used for the hot water heater of the local hot water washing means and the heater of the local drying means.
Pump motor for local hot water washing means, motor for flow rate adjustment, water shutoff solenoid valve, fan motor for deodorizing means and local drying means,
A DC power supply of 12 VDC is used for the opening / closing motor of the electric opening / closing means. Further, in the cooling means, an AC power supply of AC100V is used to drive the compressor, and a D blower is used.
A C12V DC power supply is used. A commercial power source is used as it is as an AC power source, but a DC power source obtained from a DC power source circuit is used as a DC power source.

Therefore, when the cooling means is integrally provided in the toilet device as described above, it is possible to reduce the space and cost by sharing the DC power supply circuit. However, the DC power source in the conventional toilet device is used. If a DC power supply circuit is obtained in which the power capacity of the circuit plus the power required to drive the blower of the cooling means is obtained,
Since the installation space and the cost of the DC power supply circuit increase substantially in proportion to the increase of the power capacity, there is a problem that a large space is required and the cost increases. For example, the output of the DC power supply circuit in the conventional toilet device was about 15 W, but in order to drive the blower of the cooling device, an additional output of about 15 W is required, and an output of 30 W is required. And cost 2
There is a problem that it doubles.

Further, the control of the driving force of the opening / closing motor of the electric opening / closing means is extremely delicate, and if the output of the DC power source fluctuates, the stability of the opening / closing operation is adversely affected, but the compressor of the cooling means is started. At times, there is a problem that the power consumption of the AC power source becomes extremely large, the output of the DC power source circuit fluctuates accordingly, and the operation of the electric switching means becomes unstable.

On the other hand, even though the above-mentioned Japanese Patent Application Laid-Open No. 1-281340 discloses controlling the on / off timing of the blower of the cooling and heating apparatus, it does not solve such a problem.

In view of the above-mentioned conventional problems, the present invention provides a toilet device which can suppress the space and cost of the DC power supply circuit and can secure the operation stability of the electric opening / closing means while integrally providing the cooling means. The purpose is to do.

[0009]

The toilet device of the present invention comprises:
In a toilet device comprising at least one of a cooling means by a refrigeration cycle having a compressor, a condenser, a decompressor, an evaporator and a blower, a local hot water washing means and a local drying means, a local hot water washing means during operation of the cooling means. When operating the or local drying means, the operation of the blower is stopped while the compressor is in the operating state, and the operation of the blower is restarted after the operation of the local hot water washing means or the local drying means is finished.
When the toilet device is equipped with cooling means, local hot water washing means and local drying means, if the local hot water washing means and local drying means are activated during cooling operation, the air blower of the cooling means is stopped and the operation is restarted after the operation is stopped. By doing so, it is not necessary to secure the output capacity of the DC power supply circuit so as to drive both the local hot water washing means or the local drying means and the air blower of the cooling means with a margin, and the output capacity of the DC power supply circuit is correspondingly increased. The size can be reduced, and the space and cost of the DC power supply circuit can be suppressed while integrally providing the cooling means. In addition, since the operating time of the local hot water washing means and the local drying means is usually not so long, even if the ventilation of the cooling means is stopped during that time, there is not much discomfort.

Further, in a toilet device provided with a cooling means by a refrigeration cycle having a compressor, a condenser, a decompressor, an evaporator and a blower, and an electric opening / closing means for at least one of a toilet lid and a toilet seat, operation of the cooling means When the electric opening / closing means is operated during operation, only the compressor is operated for the cooling means, and the operation of the blower is restarted after the opening / closing operation of the electric opening / closing means is completed. When the electric opening / closing means is operated during the cooling operation, the blower of the cooling means is stopped, and the operation is restarted after the operation is stopped, so that the output capacity of the DC power supply circuit is electrically opened / closed. It is no longer necessary to secure enough capacity to drive both the blower of the cooling means and the cooling means,
The output capacity of the DC power supply circuit can be reduced accordingly, and the space and cost of the DC power supply circuit can be suppressed while integrally providing the cooling means.

Further, in a toilet device provided with cooling means by a refrigerating cycle having a compressor, a condenser, a decompressor, an evaporator and a blower, and an electric opening / closing means for at least one of a toilet lid and a toilet seat, the operation of the cooling means When the start coincides with the operation of the electric opening / closing means, the cooling means is operated only by the blower, and the compressor is started after the opening / closing operation of the electric opening / closing means is finished. When the operation start of the cooling means overlaps with the operation of the electric opening / closing means, the compressor of the cooling means is not operated, so that a large electric power is required at the time of starting the compressor. The power consumption of the power supply suddenly increases and D
It is possible to prevent the output fluctuation of the C power supply circuit from occurring, and to ensure the stable operation of the electric opening / closing means. Since the operation time of the electric opening / closing means is not so long, even if the cooling means is actually operated after the opening / closing operation is finished, the operator does not feel much discomfort. Moreover, although the output capacity of the DC power supply circuit has a margin when the blower is not operated, the blower is operated in order to notify the user of the start of cooling, so that the consumed output of the blower is reduced as much as possible. It is preferable to reduce the operating state.

This will be described with reference to FIGS.

While the cooling means 7 is in operation, the local hot water washing means 21 is operated while the compressor 11 and the blower 15 are operating.
3 and the local drying means 23, as shown in FIG. 3, the operation of the blower 15 is stopped while the compressor 11 remains in the operating state, and after the local hot water washing means 21 and the local drying means 23 have finished operating. It is configured to restart the operation of the blower 15.

While the cooling means 7 is in operation, the compressor 11
And the blower 15 is operating, the electric opening / closing means 2
4 is performed, as shown in FIG. 4, the cooling means 7 is operated only by the compressor 11, and the electric opening / closing means 24 is operated.
The operation of the blower 15 is restarted after the opening / closing operation of is completed.

When the operation of the cooling means 7 overlaps with the operation of the electric opening / closing means 24, as shown in FIG.
The cooling means 7 is configured to operate only the blower 15 and to start the operation of the compressor 11 after the opening / closing operation of the electric opening / closing means 24 is completed.

According to the above construction, while the cooling means 7 is in operation, the compressor 11 and the blower 15 are operating,
The compressor 1 which uses the AC power source of the cooling means 7 when the local hot water washing means 21 and the local drying means 23 are operated.
In No. 1, the blower 15 is temporarily stopped by continuing the operation, and the operation of the blower 15 is restarted after the operation of the local hot water washing means 21 and the local drying means 23 is stopped. Hot water cleaning means 21 (DC used power is 7 W in total) or local drying means 23 (DC used power is 10 W) and blower 15 of cooling means 7 (DC used power 1
0W), it is not necessary to secure a capacity for driving both of them with a margin, the output capacity of the DC power supply circuit can be reduced accordingly, and even if the cooling means 7 is integrally provided, the output capacity of the conventional toilet device is 15W. The DC power supply circuit can be used as it is, and the space and cost of the DC power supply circuit can be suppressed.

Since the operating time of the local hot water washing means 21 and the local drying means 23 is usually not so long, even if the ventilation of the cooling means 7 is stopped during that time, there is not much discomfort. Further, since the operation of the compressor 11 is not temporarily stopped, there is no inconvenience due to the fact that the compressor 11 cannot be restarted for a certain period of time after the interruption.

While the cooling means 7 is operating, the compressor 11
And the blower 15 is operating, the electric opening / closing means 2
4 is operated, only the compressor 11 using the AC power source of the cooling means 7 is operated to stop the blower 15,
The blower 15 after the opening / closing operation of the electric opening / closing means 24 is completed.
Since the operation of the DC power supply circuit is restarted, the output capacity of the DC power supply circuit is set to the electric switching means 24 (DC power consumption is 5 W).
It is not necessary to secure a capacity for driving both the fan 15 and the blower 15 (DC power consumption 10 W) of the cooling means 7 with a margin, and the output capacity of the DC power supply circuit can be reduced accordingly, and while the cooling means 7 is integrally provided. The space and cost of the DC power supply circuit can be suppressed.

When the operation of the cooling means 7 overlaps with the operation of the electric opening / closing means 24, the cooling means 7 is operated only by the blower 15 (DC power consumption 10 W), and the opening / closing operation of the electric opening / closing means 24 is performed. By starting the operation of the compressor 11 after the end and not starting the compressor 11 during the opening / closing operation of the electric opening / closing means 24, a large amount of electric power is required at the time of starting the compressor 11, so that the AC power is consumed. It is possible to prevent the output of the DC power supply circuit from fluctuating due to a sudden increase in power, and to ensure a stable operation of the electric opening / closing means 24.

Since the operating time of the electric opening / closing means 24 is not so long, even if the cooling means 7 is actually operated after the opening / closing operation is completed, there is not much discomfort. Although the output capacity of the DC power supply circuit has a margin when the blower 15 is not operated, the blower 15 is operated in order to notify the user of the start of cooling. In that case, the DC power consumption is the maximum. It becomes 10 W + 5 W, and the output capacity of the DC power supply circuit of the conventional toilet device is 15 W, which is the limit and there is no room. Therefore, it is preferable to set the operating state in which the consumed output of the blower 15 is as small as possible.

It is preferable that the condenser 12 is composed of a meandering pipe member and is housed and arranged in the water tank 6 because the condensation heat can be radiated with a simple structure, but this is an example.
In addition, a fin tube is preferable in that the heat exchange efficiency is high. If the condenser 12 is not housed in the water tank 6 but the condenser 12 is housed in a water container (not shown) and water in the water tank 6 is circulated between the water tank 6 and the water container. It is preferable in that the space for accommodating the condenser 12 in the water tank 6 is not required, and the degree of freedom in arranging the water supply / drainage device (not shown) in the water tank 6 is increased. Furthermore, when the condenser 12 is configured with double pipes and is arranged outside the water tank 6 and water in the water tank 6 is circulated, the condenser 12 can be arranged outside the water tank 6 and This is preferable in that it can avoid problems such as corrosion on the draft surface of water that occurs when the housing is arranged.

Further, it is preferable that the decompressor 13 is constructed by winding a thin tube because decompression can be performed with a simple structure. However, this is an example, and if it is composed of a valve, the cooling load can be reduced. It is preferable in that the degree of pressure reduction can be changed according to the above. Further, it is preferable that the electronic control valve is used because the degree of pressure reduction can be automatically controlled.

Further, it is preferable that the blower 15 is composed of a sirocco fan in that the directions of suction and blowout can be made vertical and that it is resistant to pressure loss, but this is an example, and in addition, an axial fan is used. If constituted, it is preferable in that the directions of suction and blowing can be the same. In addition, it is preferable to use a cross-flow fan because a wide range of cold air can be blown out. These may be selected according to the position where the evaporator 14 is disposed, the blowing direction, and the air passage configuration.

Further, setting the DC power supply circuit to 12V is an example, and 15V or 24V may be used depending on the driving parts. Here, it is preferable to unify the voltage types rather than mixing them in order to reduce the power supply circuit space and cost.
