Description

[Detailed description of the invention]

[Field of Application of the Invention] The present invention relates to an operation control circuit for a dehumidifier, and particularly to a dehumidifier for a semi-basement that is installed through the wall of the part of the semi-basement that faces the outside air, with a part of the wall facing the outside air. Regarding machines. [Prior Art] Conventional dehumidifiers only have a dehumidifying function or have both a dehumidifying function and an air blowing function. For this reason,
When used in a basement or the like, humidity can be controlled well, but when a basement is used as a living space, the air becomes contaminated with cigarette smoke and the like, making it impossible to control the air in a desirable manner. [Object of the Invention] The object of the present invention is to automatically select and use the operation types of dehumidification, air blowing, and ventilation in a room where part of the wall of a basement faces the outside air (hereinafter referred to as a semi-basement). Our goal is to provide a dehumidifier that does the following: [Summary of the invention] In response to the recent difficulty in obtaining land and the soaring price of land, it is possible to expand the living space underground. By arranging lighting and ventilation equipment, a semi-basement can be used as a living space, but as moisture in the soil penetrates the walls, water vapor is released from the walls inside the semi-basement, resulting in high humidity. Become. This impairs livability, so a dehumidifier must be used at all times. On the other hand, in order to save energy, dehumidification operation should be stopped when the indoor humidity decreases, and when the outside air humidity is low enough, ventilation operation can be used to mix the high humidity indoor air with the low humidity outside air. All you have to do is replace the air. Furthermore, the temperature required for living in semi-basement rooms is almost constant throughout the year. Therefore, when the outside air temperature is lower than the humidity inside the semi-basement, for example in winter (outside temperature approximately 15°C or less), frequent ventilation operations should be avoided as this will cause a drop in the indoor temperature. As mentioned above, a dehumidifier is necessary to improve the livability of a semi-basement, and by making it automatic, it is possible to appropriately select each operation of dehumidification, air blowing, and ventilation, thereby saving energy. A dehumidifier that is effective as a dehumidifier for basements can be provided. [Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 shows a dehumidifier installed in a semi-basement, with 1 being a wall facing the outside air, 2 being the ground surface, and 3 being below the ground. In such a case, the moisture contained in the basement 3 passes through the wall 1, penetrates into the semi-basement 4, and evaporates, so the humidity in the semi-basement 4 becomes extremely high, making it difficult to use as a living space. It's not appropriate. Therefore, in order to maintain comfortable humidity, the amount of moisture permeable through the wall 1 is reduced and at the same time a dehumidifier is used.
Reference numeral 5 denotes a mounting frame provided on the wall 1, and the dehumidifier 6 is installed in the mounting frame 5 so as to penetrate through the wall 1 in the part of the semi-basement room where a part of the wall 1 faces the outside air. . In order to use the semi-basement room 4 as a living space, the humidity must be lowered by operating the dehumidifier 6 as described above. However, operating the dehumidifier 6 all the time increases costs and is not a good idea. 2, 3 and 4, the structure and electric circuit of the dehumidifier according to the present invention will be explained. Figure 2 shows dehumidification operation and ventilation operation;
The figure shows ventilation operation, and the arrows in the figure indicate the direction of airflow. FIG. 4 shows the electrical circuit of the dehumidifier 6. In FIGS. 2 and 3, the dehumidifier 6 is the compressor 2.
1, a condenser 22, an evaporator 23, an air blower 24, and a ventilation damper 25. (The electric motor for driving the ventilation damper is not shown.) The condenser 22 and the evaporator 23 are provided so as to overlap in the airflow direction. The electrical circuit of the dehumidifier 6 according to this embodiment configured as described above is shown in FIG.
The blower motor 44 connects the compressor motor 41 to the power supply in parallel,
The ventilation damper driving electric motor 45 is the ventilation damper 2
It is connected in series with the position detection limit switches 46 and 47 of No. 5, and in series with the power supply via a relay 48. The contacts of the relays 43 and 48 are opened, closed, or switched, respectively, by signals obtained from an indoor temperature sensor 49, an outdoor temperature sensor 50, and an outdoor temperature detection thermistor 51, and the relays 43 and 48 open, close, or switch their contacts, respectively, according to signals obtained from an indoor temperature sensor 49, an outdoor temperature sensor 50, and an outdoor temperature detection thermistor 51. With the combinations shown in the table below, appropriate operation corresponding to the outside temperature, indoor humidity, and outdoor humidity, which are the objectives of the present invention, can be achieved. That is, the control means using the electric circuit is as follows:
As shown in the table below, when the humidity in the semi-basement room 4 is lower than the set temperature, the air blowing motor 44 is operated, and when the humidity in the semi-basement room 4 is higher than the set humidity, the outside air humidity is set. When the outside air temperature is lower than the humidity and higher than the temperature in the semi-basement room 4, the ventilation damper driving electric motor 45 and the blower electric motor 44 are operated to perform a ventilation operation in which outside air is sucked into the semi-basement room 4. 4 When the humidity is higher than the set humidity, the compressor motor 41 and the blower motor 4 when the outside air humidity and outside air temperature are other than the above.
4 to control the dehumidifying operation. 52 is a secondary power transformer, and 53 is a substrate.

〔Effect of the invention〕

According to the present invention, by performing the ventilation operation when the humidity inside the semi-basement is lower than the set temperature, even if moisture in the soil permeates the wall and becomes water vapor, the humidity in the semi-basement is high in some areas. The air inside circulates to prevent this, and when the humidity inside the semi-basement is higher than the set temperature, the outside air humidity is lower than the set humidity, and the outside air temperature is higher than the temperature inside the semi-basement, outside air is sucked into the semi-basement. By performing ventilation operation,
It lowers the indoor humidity and prevents the room temperature from dropping, and if the humidity in the semi-basement is higher than the set humidity and the outside air humidity and temperature are outside the above, the dehumidifying operation is performed to lower the indoor humidity. Therefore, regardless of the humidity and temperature conditions, the humidity inside the semi-basement can be adjusted to a comfortable level and the room temperature can be eliminated, improving the livability of the semi-basement. can. In addition, by automatically switching from dehumidifying operation to blowing operation as the humidity in the semi-basement room decreases, and by sucking in low-humidity outside air, it is possible to reduce the humidity inside the semi-basement room just by operating the blower. This has the effect of reducing power consumption and reducing operation and maintenance costs.
