Description

[Detailed explanation of the idea] The present invention relates to improvements in ventilation equipment.

Some conventional ventilation devices are constructed as shown in FIG. 1, for example.

That is, in the figure, 1 is the main casing, 2 is the heat exchanger disposed at the front inside the casing 1,
3 is a damper disposed near the discharge port of this heat exchanger 2, and a bypass passage for ventilation is provided in this device when there is no need to exchange heat between intake air and exhaust air or when it is desired to increase the air volume. It is provided for the purpose of configuring a structure, and one end is supported by four supporting shafts so as to be freely rotatable. An operating handle 5 for rotationally controlling the damper 3 is provided at one end of the support shaft 4, and ventilation from the heat exchanger 2 is controlled by operating the handle 5. Reference numeral 6 denotes a decorative grille attached to the front surface of the casing 1, which has a notch (not shown) on both sides through which the support shaft 4 is inserted, and is attached to the main body casing 1 with a fixing device such as a screw 6a;
The main body casing 1 constitutes a device main body.
Note that 7 is a blower.

Further, in the figure, the arrows shown by dotted lines indicate the air supply flow, and the arrows shown by two-dot chain lines indicate the exhaust flow.

However, in such conventional devices, when the user wants to control the rotation of the damper 3, the user directly operates the operating handle 5 provided on the outside of the main casing 1, but this handle 5 is Since the handle 5 is only provided on the side, there is a problem that, for example, if there is furniture or a wall near the side where the handle 5 is provided, the handle 5 cannot be operated or is difficult to operate.

The present invention has been developed by focusing on the conventional situation, and a damper for controlling the ventilation of a ventilation system is provided with at least two engaging portions in which an operating handle for operating the damper is freely engaged. The purpose of this structure is to make it easier for the user to control the damper by selectively engaging one of the engaging parts, thereby improving operability. By attaching the handle through the grill, the purpose is to prevent the decorative board covering the front of the heat exchanger from falling.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Note that the same reference numerals are given to the same components as in the conventional example to simplify the explanation.

In the figure, 13 is a damper, which is disposed at the same position and for the same purpose as the conventional one. 14 is the damper 1
3, and is provided with engaging portions 14a at both ends. Reference numeral 15 refers to an operating handle that freely engages with the engaging portion 14a and rotates the damper 13, and reference numeral 16 refers to the casing 1.
The decorative grille serves as a decorative panel that makes up the front of the
Mounting holes 16a are formed on both side walls in correspondence with the engagement positions of the engaging portion 14a and the handle 15.

According to this configuration, when the user rotates the damper 3 for the purpose of heat exchange or the like, the user engages the operating handle 15 from the outside with the engaging portion 14a of at least one of the support shafts 14. By rotating the handle 15, the damper 13 can be operated via the support shaft 14.

Therefore, even if there is furniture or the like near one side of the device main body and obstructs the operation of the damper 13, the operation handle 15 can be easily engaged with any desired engaging portion 14a. Therefore, problems such as difficulty in operating the damper 13 depending on the installation position of the device main body can be solved.

Furthermore, if the engagement portion 14a of the operating handle 15 is engaged from the outside through the attachment hole 16a of the decorative grille 16, it is possible to attach the decorative grille 16 to the main body casing 1 using a conventional fixing device such as a screw 6a. It is possible to prevent the decorative grille 16 from detaching or falling even without using the decorative grille 16.

Furthermore, since the screws 6a are not required, there is an advantage that the assembly process can be simplified and the appearance can be improved.

In addition, in this embodiment, each engaging portion 1
4a are provided at both ends of the support shaft 4, the respective engaging portions 14a are arranged on both the left and right sides of the device main body, but it is clear that this is not necessarily limited to both sides of the device. It is.

As described above, according to the present invention, a damper for controlling ventilation provided in a ventilation system is provided with at least two or more engaging portions with which the operating handle is detachably engaged, and the operating handle is engaged with the damper for controlling ventilation. Since the damper is configured to selectively engage at least one of the parts, it is possible to prevent the damper from becoming difficult to operate depending on the installation location of the device body, thereby improving operability. Obtainable.

Since the operating handle is attached to the engaging portion through the attachment hole of the decorative grill, it is also possible to prevent the decorative grill from falling.
