[0002]

2. Description of the Related Art In recent years, a separation type air conditioner in which an outdoor unit and an indoor unit are separated has become popular in order to reduce noise in the room.
Then, there is a demand for the ventilation control device for the indoor unit of the separation type air conditioner that alleviates the sudden change in the indoor temperature when the ventilation fan provided separately from the indoor unit for performing the indoor ventilation is operated. It is rising.

A conventional ventilation control device for an indoor unit of this type of separation type air conditioner will be described with reference to FIG.
As shown in the figure, the indoor unit 101 is provided with a main control unit 102 and a sensor unit 103 for detecting the indoor temperature, and the main control unit is a remote controller (hereinafter referred to as a remote controller) 104.
Was used to instruct a desired operation mode, set temperature, etc.

The ventilation device 105 is provided with a carbon monoxide concentration detecting device 106, and the carbon monoxide concentration detecting device 10 is provided.
When carbon monoxide is detected by 6, the ventilation device 105 is operated regardless of the operating state of the indoor unit 101.

[0005]

In the conventional ventilation control device for the indoor unit of the separation type air conditioner, the indoor unit 10 is used.
In No. 1, only the air conditioning and heating of the room are performed, and the ventilation device 105 also provides only the ventilation function to perform forced ventilation of the indoor air. Therefore, there is a problem that the room temperature changes abruptly when the ventilation device 105 is operated when the outside temperature is high in the summer or when the outside temperature is low in the winter.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a ventilation control device for an indoor unit of a separation type air conditioner which can perform ventilation while keeping a room temperature constant.

[0007]

In order to achieve the above object, a ventilation control device for an indoor unit of a separation type air conditioner according to the present invention detects a carbon monoxide concentration provided in the indoor unit of a separation type air conditioner. A carbon monoxide concentration detection device, a sensor unit for detecting the room temperature, a main control unit for sending a signal to the ventilation control device according to the room temperature obtained from the sensor unit and the information from the carbon monoxide concentration detection device, A ventilation device provided in the vicinity of the indoor unit, and the operation of the ventilation device is controlled via the ventilation control device by a signal from the main control unit.

[0008]

With the above-described structure, the present invention provides an indoor unit with a ventilation control device when the outdoor temperature is high in the summer or when the outdoor temperature is low in the winter. Instead, it can also be used as a ventilation control for controlling the ventilation device, and the room can be ventilated while the room temperature is kept constant.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in the figure, the indoor unit 1 has a carbon monoxide concentration detection device 2 for detecting the indoor carbon monoxide concentration, a sensor unit 3 for detecting the room temperature, the room temperature obtained from the sensor unit 3, and the monoxide. A main control unit 5 for sending a signal to the ventilation control device 4 incorporated in the indoor unit 1 based on information from the carbon concentration detection device 2 is provided.

A ventilation device 6 whose operation is controlled by the ventilation control device 4 is provided near the indoor unit 1.

Further, the main control unit 5 has a desired operation mode,
A remote controller 7 for instructing a set temperature or the like is provided.

In the above structure, the main control unit 5 detects whether the room temperature obtained from the sensor unit 3 and the carbon monoxide concentration obtained from the carbon monoxide concentration detection device 2 are within preset conditions, If it is within the set conditions, at the time of detection of the conditions, the main controller 5 sends an operation command and a transmission command via the ventilation control device 4, and the operation of the ventilation device 6 is controlled.

Next, operation control of the ventilation device will be described based on the chart shown in FIG. First, the 11th step is started, the room temperature is detected by the sensor unit 3 in the 12th step, the carbon monoxide concentration is detected by the carbon monoxide concentration detection device 2 in the 13th step, and the 12th step is performed in the 14th step. Based on the room temperature obtained in step 1 and the carbon monoxide concentration obtained in the 13th step, the main controller 5 determines whether the ventilation device 6 is stopped. Then, if the ventilation device 6 is operating, the process proceeds to a fifteenth step, in which the operation command is transmitted to the ventilation device 6 via the ventilation control device 4.

When the result of the 14th step is no, the process proceeds to the 16th step, and in the 16th step, an operation stop command is transmitted to the ventilation device 6 via the ventilation control device 4.

As described above, according to the ventilation control device for the indoor unit of the separation type air conditioner of the embodiment of the present invention, the indoor unit 1 is ventilated when the outside air temperature in summer is high or the outside air temperature in winter is low. By providing the control device 4, not only can the indoor unit 1 be used as a heating and cooling appliance, but it can also be used as a ventilation control device that controls the ventilation device 6, and it is possible to ventilate the room while keeping the room temperature constant. It will be possible.

[0016]

As is apparent from the above embodiments, the indoor unit is provided with the carbon monoxide concentration detecting device, the sensor section for detecting the room temperature, and the ventilation control device, and the information from the room temperature and the carbon monoxide concentration detecting device is used. A signal is sent to the ventilation control device to control the operation of the ventilation device provided in the vicinity of the indoor unit, so not only can the indoor unit be used as a heating and cooling device, but it can also be used as a ventilation control device that controls the ventilation device, and room temperature It is possible to provide a ventilation control device for an indoor unit of a separation-type air conditioner that can ventilate a room while keeping it constant.
