Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for a house, which secures an optimal ventilation air volume, cleans the air quality in a room, and keeps it at a predetermined temperature and humidity.

[0002]

2. Description of the Related Art Conventionally, this type of house ventilation system has
Due to the structure of the outer wall of the house and the accommodation of the interior and walls, it has a square or round air supply port. This air supply port is equipped with an opening / closing mechanism that can be operated by the user in order to prevent harmful effects due to the intake of outside air, especially in the cold, and a movable mechanism that can open and close the internal damper in conjunction with the control of the entire ventilation system. Some have. Further, in order to supply a required ventilation amount to each room using a duct, there is also one having a damper mechanism for controlling the ventilation air amount at the air supply port.

Incidentally, such a technique is disclosed, for example, in "Comprehensive Catalog", January 1995, published by KYOWANASTA Co., Ltd.,
"Housing air conditioner" Residential air multi, November 1994 edition, published by Mitsubishi Electric Corporation.

[0004]

However, the present inventor has found that the above-described ventilation system for a house has the following problems. That is, when the outside air temperature is low, it is cold due to the intake of outside air (draft).
In many cases, the user operated the opening / closing mechanism to limit the amount of outside air taken in. However, if the intake of outside air is limited, the required ventilation cannot be obtained, air pollution in the room spreads, and condensation, mold and mites occur due to the accumulation of humidity.

When the damper mechanism is used to control the ventilation air volume, it is conceivable that the damper mechanism is opened and closed electrically. To open and close the damper mechanism, operation control in both the opening and closing directions is required. Control signal line is required. For this reason, erroneous connections will occur during construction. In view of the above-mentioned problems, an object of the present invention is to provide a ventilation system for a house that does not have a feeling of cold, can keep the air quality in the room clean, and is easy to construct. The above and other objects and novel features of the present invention will be apparent from the description of the present specification and the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings. Here, FIG. 1 is a perspective view showing an installation state of a house ventilation system according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a supply port of the house ventilation system according to the embodiment of the present invention. Show. Also, components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments, and the repetitive description thereof will be omitted.

That is, the ventilation system in the house is the house 1
An air supply port 3 for introducing outside air is bored in the outer wall 2 of the
Ventilation means capable of performing the entire ventilation and varying the ventilation amount, for example, a ventilation fan 4 capable of changing the rotation speed is provided. On the indoor side of the air supply port 3, an air supply changing means, such as a louver 8, that changes the direction and amount of air supplied to the room is attached. In addition, in the room, a control unit 5 that controls the wind direction of the louver 8 and the air supply amount, and further controls the ventilation amount of the ventilation fan 4.
The control unit 5 is connected to the louver 8 and the ventilation fan 4 via two control lines 6.

A WAX element 7 is mounted on the outer wall 2 side of the air supply port 3 as a driving means for driving the louver 8, and a temperature / humidity sensor 10 for detecting temperature and humidity is provided indoors and outdoors.
Are respectively arranged and connected to the control unit 5. Here, the WAX element 7 is an element in which the cylinder is filled with WAX via a piston, and the thermal expansion force of the WAX due to heating presses the piston and operates to the outside. Since the amount of movement is small, the movement force is large, and since it is small and the movement mechanism is simple, it can be easily accommodated inside a pipe-shaped air supply port such as a round shape.

The louver 8 includes a column 8a and an operating plate 8b extending in the vertical direction of the air supply port 3, and a plurality of flat plates 8c axially supported at predetermined intervals in the longitudinal direction of the column 8a and the operating plate 8b. The operating plate 8b includes an arm portion 8d whose one end is axially supported. The arm portion 8d is connected to the projecting piece 7a projecting downward of the WAX element 7, and the vertical movement of the projecting piece 7a by the WAX element 7 is transmitted to the actuating plate 8b through the arm portion 8d to change the direction of the flat plate 8c. By doing so, the angle of the louver 8 in the outside air blowing direction can be changed.

A heater 9 such as a posistor is embedded in the upper portion of the WAX element 7, and electric power is supplied from the control section 5 through the two control lines 6. The temperature of the heater 9 is determined by the supply voltage, which determines the operation amount of the WAX element 7. The control unit 5 is an indoor / outdoor temperature / humidity sensor 1
Based on the temperature and humidity detected by 0, the required ventilation amount in the room and the airflow direction and air volume of the air supply to the room are determined, and then the control voltage is supplied to the heater 9 to control the temperature of the heater 9.

Then, the WAX element 7 whose operation amount changes according to the temperature change of the heater 9 changes the air flow direction and air amount of the air supply to the room. That is, when the outside air temperature is not so low, the louver 8 is made substantially horizontal so that the outside air can easily enter the room, and a voltage is applied so as to actively perform ventilation. On the other hand, when the outside air temperature is low, the louver 8 is turned upward according to the outside air temperature to limit the air supply amount, prevent the outside air from directly contacting the occupants, and mix it with the air in the upper part of the room (near the ceiling). By combining them, the coldness of the outside air is softened and the feeling of coldness is prevented.

At the same time, the rotation speed of the ventilation fan 4 is controlled by the control voltage from the control unit 5 so that the ventilation amount in the room is optimized. As described above, in the present embodiment, the wind direction, the air volume, and the ventilation volume of the supply air are controlled based on the change in the supply voltage from the control unit 5 depending on the temperature and humidity inside and outside the room. Accordingly, it is possible to always secure a necessary ventilation amount, eliminate the feeling of cold, clean the indoor air, and prevent dew condensation.

Further, since the WAX element 7 is controlled only by the temperature change of the heater 9 and the WAX element 7 and the ventilation fan 4 are controlled by the same controller 5, the system structure is simplified. Therefore, the construction is simplified, and it is possible to prevent misconnection of wiring. Furthermore, when the louver 8 is operated by a motor or the like, a so-called gear conversion unit that reduces the rotation speed of the motor and converts it into a large force is required. However, when the WAX element 7 is used, this is unnecessary. Becomes Therefore, the drive portion of the louver 8 can be downsized, and the air in the air supply port 3 can be smoothly flowed.
In addition, since the WAX element 7 can obtain a strong operating force even if it is small, by electrically controlling the heater 9, the louver 8
Can be operated easily.

As described above, the inventions made by the present inventor are
Although the present invention has been specifically described based on the embodiments, it goes without saying that the present invention is not limited to the embodiments and various modifications can be made without departing from the scope of the invention.
In this embodiment, the louver 8 is used as the air supply changing means, but instead of this, an opening / closing damper may be used and the air supply amount to the room may be controlled by moving the opening / closing damper.
