Description

[0001]
[Industrial application fields]
The present invention relates to a dehumidifier using a refrigeration apparatus.
[0002]
[Prior art]
Conventionally, this type of dehumidifier will be described with reference to the drawings.
[0003]
In FIG. 7, the dehumidifier main body 1 is composed of a suction grill 2, an outer box 3 and a blow-out grill 4, inside which are a compressor 6, a condenser 7, an expansion device 8, an evaporator 9 and a blower 10 constituting a refrigeration cycle. And a fan 11. The dehumidified water generated from the evaporator 9 is dropped from a cylindrical drain port 13 provided in the water receiving tray 12 and accumulated in the drain tank 14. Reference numeral 16 denotes a lever that closes the drain port 13 through a plug 15, and a spring 17 presses the plug 15 attached to the lever 16 against the drain port 13 (Japanese Patent Laid-Open No. 6-34158).
[0004]
FIG. 8 is an operation diagram of the lever 16 when the drain tank 14 is set in the main body 1.
[0005]
FIG. 9 is an operation diagram of the lever 16 when the drainage tank 14 is extracted from the main body 1, and FIG. 10 is a perspective view of the lever in the conventional dehumidifier.
[0006]
[Problems to be solved by the invention]
However, in the configuration as described above, the dehumidified water generated from the evaporator 9 is dropped from the water receiving tray 12 and the cylindrical drain port 13 provided in the vertical direction and collected in the drain tank 14. When draining the dehumidified water accumulated in the drain tank 14, the drain tank 14 is removed from the main body 1, so that the lever 16 to which the stopper 15 is attached closes the drain port 13 from below. When provided in the vertical direction, the dehumidified water adhering to the evaporator 9 and the water tray 12 does not drip onto the substrate 5 even with the structure of the lever 16. However, when the drain port 13 is provided in the horizontal direction, the lever 16 to which the plug 15 is attached closes from the rear of the drain port 13, and the drain port 13 and the plug 15 attached to the lever 16 The dehumidified water leaks from the space and drops onto the substrate 5, and the floor on which the dehumidifier body 1 is installed also gets wet.
[0007]
The present invention solves the above-described problems of the conventional example, and aims to prevent the floor surface from being wetted with dehumidified water by a simple device.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a compressor, a condenser, an evaporator, a water tray and a drain tank for receiving water dripped from the evaporator inside the dehumidifier body, and a drain in the water tray. Provided with a spherical protrusion facing the drain port on the lever that is interlocked with the drainage of the drainage tank, and an elastic stopper that closes the drainage port when the drainage tank is removed. It is arranged between the protrusions. Further, the lever is formed so that the radius of the spherical protrusion provided at the tip of the lever is equal to or less than ½ of the inner diameter of the drain opening portion.
[0009]
[Action]
The effect | action by the said means is as follows.
[0010]
The present invention includes a compressor, a condenser, an evaporator, a water tray and a drain tank for receiving water dripped from the evaporator inside the dehumidifier body, a drain port is provided in the water tray, and the drain tank A spherical projection that faces the drain port is provided on the lever that moves in and out, and an elastic plug that closes the drain port when the drainage tank is released is placed between the drain port and the spherical projection. Thus, when the drainage tank is not set on the main body, dripping of the dehumidifying water adhering to the evaporator and the water receiving tray can be prevented, thereby preventing the floor surface from being wetted. In addition, by having a lever formed so that the radius of the spherical protrusion provided at the tip of the lever is ½ or less of the inner diameter of the drain port opening, the inner pressure of the plug pressed against the drain port The degree of adhesion between the drain port and the stopper is improved, and dripping of dehumidified water can be prevented.
[0011]
【Example】
Hereinafter, a dehumidifier according to an embodiment of the present invention will be described with reference to the drawings.
[0012]
In FIG. 1, an example in which the drain port is in the horizontal direction and a stopper is provided on the rear side will be described. The dehumidifier body 1 is composed of a suction grill 2, an outer box 3, and a blow-out grill 4. It has. The dehumidified water generated from the evaporator 9 is dropped from a drain port 13 formed in a cylindrical shape extending in the horizontal direction provided in the water receiving tray 12 and collected in the drain tank 14. Reference numeral 16 denotes a lever for closing the drain port 13 via the plug 15. A spherical projection 18 is provided at the tip of the lever 16, and the radius of the spherical projection 18 is less than ½ of the inner diameter of the drain port opening. It is formed as follows. Further, the spring 17 presses the plug 15 attached to the lever 16 against the drain port 13.
[0013]
The said structure WHEREIN: When the waste_water | drain tank is not set to a main body, dripping of the dehumidification water adhering to an evaporator or a water receiving tray can be prevented.
[0014]
Therefore, wetting of the floor surface can be prevented.
FIG. 2 is an operation diagram of the lever 16 when the drain tank 14 is set in the main body 1.
[0015]
FIG. 3 is an operation diagram of the lever 16 when the drain tank 14 is extracted from the main body 1.
[0016]
FIG. 4 is a perspective view of the lever 16. FIG. 5 is a dimensional relationship diagram between the drain port 13 and the lever 16.
[0017]
In FIG. 6, a spherical protrusion 18 is provided on the lever 16, and the stopper 15 is attached to the lever 16 at a position where the back surface is pushed by the protrusion 18, and the stopper 15 is located between the drain port 13 and the lever 16. Is provided. When the drain port 13 is closed, the projection 18 presses the back surface of the plug 15, and the dripping is prevented by the contact between the drain port 13 and the plug 15.
[0018]
【The invention's effect】
As is apparent from the above description, the present invention has a compressor, a condenser, an evaporator, a water tray and a drain tank for receiving water dripped from the evaporator, and a drain in the water tray. Provided with a spherical protrusion facing the drain port on the lever that is interlocked with the drainage of the drainage tank, and an elastic stopper that closes the drainage port when the drainage tank is removed. By arranging between the protrusions, it is possible to prevent dripping of the dehumidified water adhering to the evaporator and the water receiving tray when the drainage tank is not set in the main body. In addition, by providing a lever formed so that the radius of the spherical protrusion provided at the tip of the lever is ½ or less of the inner diameter of the drain opening, the inner pressure of the plug pressed against the drain opening The degree of adhesion between the drain port and the stopper is improved, and dripping of dehumidified water can be prevented. Therefore, it is possible to prevent the floor surface from being wetted by providing the spherical protrusion on the lever.
