Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duct type air conditioner to be installed in a sanitary space such as a bathroom, a lavatory, and a toilet.

2. Description of the Related Art Conventionally, air conditioners for sanitary, such as bathrooms, washrooms, and toilets, have heat sources such as a heat pump type, an electric heater type, and a hot water type. There is an embedding, etc., but most of them are for one of the rooms. For the multi-chamber type, there are a hot water type, a heat pump type, and a combination thereof. In the hot water type, there is a type in which a hot water pipe is provided in a house and a fan convector is installed in each of the above rooms, but it is used only for heating and cannot be used for cooling. There is a multi-type heat pump system, but there is no small-capacity indoor unit for each room, and an indoor unit for living room is used or air is blown from an indoor unit for living room through an air conditioning duct.

On the other hand, in each of the rooms, ventilation is indispensable due to the removal of water vapor and odor, but when a ventilation device is installed, as shown in FIG. 12, a ventilation device 52 is installed separately from the air conditioner 51 to control ventilation. In addition to the ON / OFF switch 53 of the air conditioner 51, a ventilator ON / OFF switch 54 may be installed separately, or an air conditioner 61 as shown in FIG. 13 may be installed. Air passing through the air-conditioning room is sucked in from the air-conditioned room, and the hot air after the heat exchange is sent into the same room, while air passing through the evaporator 63 is also sucked in from the air-conditioned room, and the cold air after the heat exchange is discharged outside the room for ventilation. I was going.

Japanese Patent Application Laid-Open No. 64-28432 discloses a ventilating air-conditioning apparatus for ventilating and cooling / heating the entire building.

Problems to be Solved by the Invention However, the above-described conventional air conditioners have the following problems.

In the washroom, steam generated by the use of hot water is generated under cooling and heating conditions, and the bathroom is similarly generated under heating conditions. On the other hand, toilets generate odors due to excretion under cooling and heating conditions.

First, if ventilation for cooling or heating operation is required by separately installing a ventilation device, the operation switch of the ventilation device must be pressed separately from the operation switch of the air conditioner, so the number of operations increases. .

Secondly, when an air conditioner equipped with a ventilation function is arranged and ventilation for cooling or heating operation is required, the air to be ventilated passes through the heat exchanger so that the amount of ventilation is limited to cooling or heating. This is one factor that affects the performance, and when the load of cooling or heating is large, the amount of heat exchange airflow also increases, so that the ventilation volume increases.

Third, in a ventilation air-conditioning system that performs ventilation and cooling / heating of the entire building, it is difficult to individually control the amount of ventilation. To reduce only the amount of ventilation in one room, the amount of overall ventilation decreases.

Fourth, in the above-described conventional example, there is no control based on the relationship between the indoor temperature and the indoor set temperature. When the indoor temperature reaches a set temperature obtained by adding a certain value to the indoor set temperature in the toilet, the indoor-side ventilation is stopped. In the case where the ventilation volume is the same, there is a large heat loss during cooling and heating, and there is a problem in terms of comfort such as cold feet during heating, and if the ventilation is stopped, the odor flows out to the corridor etc. when using the toilet There is fear.

Fifth, in the bathroom and bathroom, when the indoor temperature is stopped when the indoor temperature reaches a set temperature obtained by adding a certain value to the indoor set temperature, if the ventilation volume is the same, heat loss is large during heating and the bathroom Since the inside is undressed, the feeling of cool wind increases depending on the positional relationship between the ventilator and the air inlet.

Sixth, in the conventional example, although there is no particular description of the difference in the ventilation volume between the time of cooling or heating and the time of single ventilation,
If the ventilation volume during cooling or heating is the same as that during single ventilation, the indoor static pressure during single ventilation will be lower than during cooling or heating, making it difficult to open and close the door, and the amount of inflow from the inlet Therefore, there is a problem that the sound passing through the intake port increases due to an increase in the number of airflows.

Seventh, in the conventional example, the case of using the toilet when cooling or heating is stopped and when the single ventilation operation is stopped is not described, but in the above-described situation, go to the room where the operation switch of the air conditioner is installed. Ventilation operation or cooling / heating operation switch must be pressed.

In view of the above-mentioned conventional problems, the present invention facilitates ventilation operation and is affected by the performance of an air conditioner in an air conditioner intended for each room requiring ventilation, such as a bathroom, a toilet, and a toy. The purpose is to control the ventilation volume without any.

Another object of the present invention is to improve the comfort during ventilation and air conditioning of a toilet.

Another object of the present invention is to improve comfort during ventilation and air conditioning in a bathroom.

Another object of the present invention is to appropriately control the static pressure of a room to be ventilated during a single operation of ventilation when the cooling or heating operation is stopped.

Another object of the present invention is to perform a ventilation operation for preventing outflow of odor without operation of an operation switch of an air conditioner when a toilet is used when cooling or heating is stopped and when a single ventilation operation is stopped. .

When,
A comparing means for comparing the temperature detected by the temperature detecting means with a set temperature obtained by adding a certain value to the indoor set temperature; and the comparing means, when the temperature is lower than the set temperature during cooling, and when the temperature is large during heating, the ventilation of the toilet is performed. An output means for reducing the amount is provided.

A temperature detecting means for detecting a room temperature in the bathroom;
The comparison means compares the temperature detected by the temperature detection means with a set temperature obtained by adding a certain value to the indoor set temperature, and the comparison means sets the ventilation of the bathroom when the cooling temperature is smaller than the set temperature, and when the heating temperature is larger than the set temperature. It is provided with output means for stopping.

Further, when the air conditioning operation of the indoor unit is stopped, when the ventilation device of a room such as a bathroom, a toilet, a toilet, etc. is operated, a switching means for reducing the ventilation volume of the ventilation device is provided. Further, when the air conditioning operation of the toilet is stopped and when the ventilation operation is stopped, there is provided switching means for switching to the ventilation operation by the detection means for detecting the use of the toilet.

The present invention provides an air conditioner for each room requiring ventilation, such as a bathroom, a toilet, and a toilet, with the above-described configuration. In the air conditioner, a ventilation device is separately installed to perform air conditioning for cooling or heating operation. By performing the control by the control device of the air conditioner, the ventilation amount can be controlled without being affected by the performance of the air conditioner, and the ventilation operation can be facilitated.

In addition, the present invention accurately grasps the cooling and heating loads of the toilet, and reduces the amount of ventilation when cooling or heating with low load is stopped, thereby preventing the feeling of cold air at the feet and preventing the smell from flowing out when using the toilet. Therefore, the comfort during ventilation and air conditioning of the toilet can be improved.

Comfort can be improved.

In addition, the present invention appropriately controls the static pressure by reducing the ventilation volume of the room where the ventilation operation is performed when the ventilation or the heating operation is stopped when the cooling or heating operation is stopped, thereby making it difficult to open and close the door and increasing the inflow amount from the intake port. This can prevent an increase in the passing sound of the intake port due to this.

Further, in the case of using the toilet when cooling or heating is stopped and when the individual ventilation operation is stopped, by performing the ventilation operation by the toilet use detection means without operating the operation switch of the air conditioner, the odor to the corridor or the like can be obtained. Outflow can be prevented.

Can be prevented.

Next, a second embodiment will be described with reference to FIGS.

Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The toilet room temperature sensor 21 shown in FIG. 5 corresponds to the toilet room temperature detecting means shown in FIG. 4, the comparator 22 shown in FIG. 5 corresponds to the comparing means shown in FIG. The computer 23 corresponds to the transition means of FIG. 4, the output circuit 24 of FIG. 5 corresponds to the output means of FIG.
The setting temperature circuit 25 in FIG. 5 corresponds to the temperature setting value in FIG.

The operation of the control circuit configured as described above will be described with reference to FIGS. 1 to 5 and FIG. For example, in the heating operation, the toilet room temperature is detected by the toilet room temperature sensor 21 and is compared with the set temperature obtained by adding a certain value to the toilet room set temperature by the comparator 22. When the motor 4B is open, it blows air from the outlet grill 7 of the toilet, and ventilates the toilet.
The twelve ventilation motors 12A operate at a high ventilation air volume.

On the other hand, when the detected temperature is higher than the set temperature, the toilet damper motor 4B operates so as to close the damper, thereby stopping the ventilation from the toilet grill 7 and ventilating the toilet ventilation device 12. Motor 12A operates with a low ventilation air volume. At this time, in the case of the operation with only the toilet, the indoor fan motor 2A, the compressor 9A and the outdoor fan motor 9B stop operating.

The operation of the control circuit configured as described above will be described with reference to FIG. 1, FIG. 2, FIG. 3, FIG. 7, and FIG. For example, in the case of the heating operation, the room temperature in the bathroom and bathroom is detected by the bathroom and bathroom room temperature sensors 31 and 41, and the detected temperature is added to the room temperature in the bathroom and bathroom by a set temperature and the comparators 32 and 42. If the temperature is lower than the set temperature, the toilet and bathroom damper motors 4A and 4C
In the open state, air is blown from the outlet grill 7 in the bathroom and bathroom, and the ventilation motors 11A and 13A of the ventilation devices 11 and 13 in the bathroom and bathroom are operated at a high ventilation air volume.

On the other hand, when the detected temperature is higher than the set temperature, the toilet and bathroom damper motors 4A and 4C operate so as to close the damper, and the outlet grill 7 of the bathroom and bathroom.
And the ventilation motors 11A and 13A of the lavatory and bathroom ventilation devices 11 and 13 also stop ventilation. In addition, at this time, in the case of operation of only the bathroom or the bathroom, the indoor fan motor 2A, the compressor 9A, and the outdoor fan motor 9B stop operating.

In the case of the cooling operation, when the detected temperature of the lavatory is lower than the set temperature, the damper motor 4A of the lavatory operates to close the damper, and stops the air supply from the blowout grill 7 of the lavatory. The ventilation motor 11A of the lavatory ventilation device 11 also stops ventilation.

As described above, according to the third embodiment, the toilet and bathroom indoor temperature sensors 31 and 41 are provided to compare the room temperature of the toilet and bathroom with the set temperature of the toilet and bathroom. Control ventilation and stop ventilation of the ventilation system in the bathroom and bathroom, and stop the ventilation when the temperature is below the temperature of the bathroom during cooling and above the temperature of the bathroom and bathroom during heating. At the same time, the ventilation of the ventilation device is stopped to maintain the set temperature, and it is possible to reduce heat loss during heating due to ventilation and heat intrusion during cooling. Especially, bathrooms are mostly used when they are used, and washrooms are undressed when used as undressing rooms. The flow of air flowing through the door gallery of the place and the bathroom can improve comfort problems such as cold body and feet.

And the air-conditioning duct 6. Further, the compressor / fan motor relay 15 is closed and the indoor fan motor 2A, the compressor 9A and the outdoor fan motor are operated, so that cool air or hot air is blown from the outlet grill 7 in the washroom. The same applies to other air conditioning operation switches.

On the other hand, when the ventilation operation switch 8D of the lavatory is turned ON instead of the air conditioning operation switch, only the ventilation motor 11A of the lavatory is operated with weakness. Similarly, when the toilet ventilation operation switch 8D and the bathroom ventilation operation switch 8E are turned ON, the toilet ventilation motor 12A and the bathroom ventilation motor 13A are similarly operated with a weakness.

Since only the ventilator in the room that was turned on is weakly operated by the operation, the ventilation air volume is varied according to the presence or absence of air conditioning operation, the static pressure in the room can be properly maintained at a negative pressure, and it is difficult to open and close the door or intake air Since the amount of inflow from the mouth increases, the sound passing through the inlet does not increase.

Further, a fifth embodiment of the present invention will be described with reference to FIG.

Here, the same components as those in the previous embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the sequence circuit diagram of FIG. 11, reference numeral 8E denotes a toilet ventilating operation switch, and reference numeral 36 denotes a toilet entrance detection switch. The open contact 8E 'of the toilet ventilation operation switch 8E is connected to the weak side of the toilet ventilation motor 12A, and the closed contact 8E ″
