BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacity and noise adjustment device for an air conditioner using a through fan as a blower.

0002

2. Description of the Related Art According to Japanese Unexamined Patent Publication No. 63-14020, a method for reducing noise while maintaining blower efficiency in an air conditioner using a cross-flow fan is invented. However, for example, when using it in a bedroom, it may be better to keep the noise quiet even if the cooling/heating capacity decreases, or when using it in a store, it may be better to improve the cooling/heating capacity even if the noise is high. In some cases, it may be preferable to Conventional technology has not been able to respond to such detailed needs of users.

0003

[Problem to be solved by the invention] In an air conditioner that uses a cross-flow fan as a blower, the air volume that affects the cooling and heating capacity and the noise that affects comfort are determined by the installation position of the nose part that is paired with the through-flow fan. (The distance between the through fan and the nose section) is closely related, and if one is improved, the other will deteriorate. In the conventional technology, the optimal value was adopted for the product after considering the balance between capacity and noise, so when using the product in a bedroom, even if the heating and cooling capacity is slightly reduced, the noise is still quiet. It was not possible to change the balance between power and noise according to the detailed needs of the user.

[0004] An object of the present invention is to provide a means for selecting the balance between power and noise according to the user's needs.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a mechanism that allows changing the shape and mounting position of the nose portion, and by making it selectable, balances performance and noise. Made it adjustable.

[0006]

[Function] By making the nose part variable, the distance between the nose part and the once-through fan, which greatly affects the performance of a once-through fan, can be changed, making it possible to achieve the performance of a once-through fan.If you want to reduce noise, use this nose. The balance between performance and noise can be changed by increasing the distance between the fan and the cross-flow fan, or conversely decreasing it if you want to improve heating and cooling performance.

[0007]

Embodiments An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

FIG. 1 is a sectional view of a wall-mounted air conditioner using a cross-flow fan 3. As shown in FIG. As shown in Figure 2, the nose part is fitted in 1, and can be replaced with a nose of a different shape.
By changing the dimensions of the nose portion 4 and the distance a between the cross-flow fan and the nose portion 4, it is possible to select the balance between air volume and noise.

Furthermore, the same effect as above can be obtained by using a mechanism that can move the nose part up and down as shown in FIG. 3. By connecting this mechanism to a temperature sensor, a noise measuring device, etc.
For example, when used in a bedroom, the user can select the balance between air volume and noise to suit the user's detailed needs, such as reducing noise when the room temperature gets close to the set temperature. .

0010

[Effects of the Invention] According to the present invention, if the nose part of an air conditioner can be manually replaced, the balance between air volume and noise can be set over a wide range according to user needs (installation location of the air conditioner, etc.) can do. In addition, if the nose section is automatically variable, the nose section can be set to increase the air volume during strong winds, providing powerful air conditioning and heating, and during weak winds.
By setting the nose part to reduce noise, it will be possible to respond to hourly needs from users, such as heating and cooling at night.
