Description

[Detailed description of the invention] This invention relates to an improvement in the ventilation duct structure of air conditioners such as dehumidifiers, which enables not only indoor dehumidification but also drying of objects to be dried. One of the purposes is to enable easy switching.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is the dehumidifier main body, in which an inlet 2 and an outlet 3 are formed on both sides, a rotatable handle 4 and an operating part 5 are provided at the top, and the back is provided with a power cord 6.

Inside this main body 1, a compressor 7, an evaporator 8, a condenser 9
a refrigeration cycle consisting of a refrigeration cycle, a water tray 10 provided at the bottom of the evaporator 8 and the condenser 9, and a water tray 10 that stores water and stops the operation of the refrigeration cycle when a predetermined amount of water is received. The receiver has a structure 11, the suction port 2 and the blowout port 3.
Each of the air blowers 12 is provided with a blower device 12 that communicates with each of the air blowers.

Next, this blower device 12 will be explained based on FIG. 4.

In the figure, 13 is a fan casing that communicates with the suction port 2 and has a ventilation passage 14, 15 that is branched into two.
An impeller 16 connected to a motor (not shown) is provided inside.

Reference numeral 17 denotes a damper for controlling the amount of ventilation to the one ventilation path 14, which has a small opening 18, and is opened and closed by the operation control unit 5 via a wire 19.

Here, the ventilation passage 14 communicates with the air outlet 3.

Reference numeral 20 denotes a blowout duct which is rotatably provided at the opening of the ventilation passage 15, and is provided with a shielding plate 21 which rotates in conjunction with the rotation of this duct 20.

This shielding plate 21 is rotatably supported by a supporting member 20a at one end thereof, and is urged by a spring 22 so as to be always open.

The other end of the shielding plate 21 is always in contact with the inner end surface of the support member 20a of the duct 20, and when the ventilation passage 15 is closed by the shielding plate 21, it comes into contact with the side end surface of the support member 20a.

Reference numeral 23 denotes an air conditioning operation switch that is turned on and off in conjunction with the rotation of the duct 20, and is turned on only when the duct 20 is in the normal position.

This switch 23 is for controlling the operation of the motor of the impeller 16 and the refrigeration cycle, and when the duct 20 is located at the chain double-dashed line in FIG. The formed electric circuit is turned off, and turned on when it is put into use as shown by the solid line.

That is, the operation operation unit 5 has a changeover switch (not shown) that switches between a plurality of electric circuits according to the operation menu, and the air conditioning operation switch 23 switches one of the electric circuits (the duct 20 (operation menu to be used).

Reference numeral 24 denotes an electric heater disposed within the ventilation path 15, and is connected in series with the air conditioning operation switch 23.

Here, the air conditioning operation switch 23 is assumed to control the air conditioning operation, but it may be configured to control the operation of only the electric heater 24 as necessary.

25 is a holder that holds the duct) 20.

Next, an example of the operation of the dehumidifier having the above configuration will be described.

First, in a normal dehumidifying operation, the refrigeration cycle and impeller 16 are operated with the duct 20 housed in the main body 1 as shown in FIGS. 1 and 2.

Therefore, air flows from the suction port 2 to the fan casing 13.
Since the ventilation path 15 is blocked by the shielding plate 21, it flows into the ventilation path 14 and is blown out from the air outlet 3.

In this flow, the evaporator 8 and condenser 9 dehumidify the air.

When drying items such as futons or drying small rooms such as closets, the duct 20 is rotated from the main body 1 as shown by solid lines in FIGS. 3 and 4, and the ventilation passage 15 is connected to the fan casing 13. communicate with.

This operation turns on the air conditioning operation switch 23.

Then, by closing the damper 17, the suction port 2
The dehumidified air that has flowed into the fan casing 13 from the fan casing 13 is heated by the heater 24 and blown out from the blow-off duct 20.

At this time, since the damper 17 is provided with a small opening 18, a part of the damper 17 flows toward the ventilation path 14 side, and
It also prevents the air passing through the interior from rising abnormally.

As is clear from the above embodiments, the ventilation passage structure of the air conditioner according to the present invention includes a main body of the air conditioner that is equipped with at least a suction port and a heat exchanger, and a blower impeller that communicates with the suction port and is provided inside the air conditioner body. A fan casing equipped with a fan casing, and an air passage communicating with the air outlet side of the fan casing and branching into two are provided, one of the air air passages is used as the air outlet of the main body, and the other air passage is rotatable. This system is equipped with a control device such as a shielding plate that controls communication between the fan casing and the duct in conjunction with the rotation of the duct. Air is blown out, and when the blow-off duct is used, the air can be blown out from the blow-off duct by operating the control device, making it easy to switch the ventilation path according to the application, and this can be done simply by rotating the blow-off duct. This improves usability.

In addition, by providing an air conditioning operation switch that operates in conjunction with the control device, it is possible to prevent the air-conditioning duct from operating in an incorrect state (for example, a state other than the normal position of the air-air duct), and there is no problem caused by misuse. It has various advantages.
