[Detailed description of the invention] (Industrial application field) This invention relates to a cold/hot air fan that freely switches between cold and hot air and discharges it.The purpose of this invention is to prevent wind noise when hot air is discharged and to improve heating efficiency. The aim is to provide hot and cold air blowers that can

(Prior Art and its Problems) Conventionally, there is a cold/hot air blower shown in FIG. 2 that freely switches between cold air and hot air.

This conventional cold/hot air fan a has a fan case e with a built-in fan d that sucks and blows air passing through a pumping filter c, and a cold air outlet g is provided in the air outlet f of the fan case e. communicated,
On the other hand, a hot air delivery duct i with a built-in heater h is extended from a position different from the air outlet f of the fan case e, and in the case of cold air operation, the water pumping filter c is moved and connected to the water pumping filter c. The outside air is impregnated with water and passed through this pumping filter c, and the heat of vaporization is taken from the outside air by the evaporation of the water in this pumping filter c, and this is made into cooling air, and this is released as cold air from the cold air outlet g, On the other hand, in the case of warm air operation, the pumping filter c is stopped and the pumping filter c
is kept in a dry state, outside air is passed through the water pumping filter c, and the air is switched from the air outlet f to the hot air sending duct i, where it is heated by the heater h and released as hot air.

In addition, humidifying hot air operation can also be performed by driving the water pumping filter c during hot air operation.

However, in the heating operation of the conventional cold/hot air fan a, when switching the air from the fan d from the air outlet f to the hot air delivery duct i, multiple Since this was done by turning the vertical louvers j horizontally and closing the cold air outlet g, wind noise was generated due to leakage of the blown air from the gap between the louvers j and j.

In addition, when the cold air outlet g is blocked by the louver j, the air from the fan d is not smoothly guided to the hot air delivery duct i and causes turbulence.
Warm air could not be sent out smoothly, resulting in poor heating efficiency.

(Issues to be solved by the invention) In view of the above-mentioned circumstances, there has been a desire in the industry to create a cold/hot air fan that can prevent wind noise and improve heating efficiency.

(Means for solving the problem) In this invention, a fan case with a built-in fan that sucks and blows the vortex air of the pumping filter is arranged inside the main body case, and a shielding plate can be opened and closed at the air outlet of this fan case. A wind direction guide is formed on this shield plate to change the direction of air blowing from the fan in the closed position, and a hot air delivery duct with a built-in heater extends from the fan case in the direction of air blowing changed by this wind direction guide. The above problem is solved by providing a hot and cold air fan made of

As shown in FIG. 1D, an endless belt-shaped pumping filter 7 is vertically installed in the main body case 2, facing the intake port 6.

The pumping filter 7 is freely drivable, and its lower end is inserted into the water tank 8.

A fan case 10 with a built-in fan 9 is disposed within the main body case 2 and sucks the air passing through the pumping filter 7 and blows the air.

As the fan 9, a horizontal cross-flow fan is used.

The fan case 10 has a horizontal cylindrical shape, and has a suction port 11 formed in its lower part and an air blowing port 12 formed in its front part.

A shielding plate 13 is attached to the air outlet 12 so as to be openable and closable.

The shielding plate 13 has a flat plate shape, and is guided in guide grooves 14 formed on both side edges of the air outlet 12 so as to be slidable up and down, as shown in FIG. 1E.

The vertical sliding operation of the shielding plate 13 is performed by the interlocking mechanism 15.
It is done through.

To explain the structure of the interlocking mechanism 15, reference numeral 16 is a lever arm with a shielding plate operation lever 17 attached to the base end, and this lever arm 16 is connected to a pivot shaft 18 in the center.
The base end of an interlocking arm 19 is linked to the tip of this lever arm 16 via a pivot pin 20, and this interlocking arm 1
The tip of 9 is connected to the shielding plate 13 via a pivot pin.

The interlocking mechanism 15 is fixed at the opening and closing positions of the shielding plate 13 by the elastic restoring force of the spring 21 attached to the lever arm 16.

A fan 9 is mounted on the upper part of the shielding plate 13 in its closed position.
A wind direction guide 22 is formed to change the direction of air blowing from.

The wind direction guide 22 is eave-shaped and is formed as an arcuate surface connecting the ceiling part 23 of the fan case 10 and the lower part of the shielding plate 13 at the closed position of the shielding plate 13. change from forward to downward.

The configuration of the cold/hot air fan 1 according to an embodiment of this invention is as described above, and the method of using the same will be explained below.

First, when performing cold air operation, it is sufficient to set the shielding plate 13 to the open position and drive the fan 9 while driving the pumping filter 7, and the outside air is taken in from the intake port 6 and passes through the pumping filter 7. The heat of vaporization is removed by the evaporation of the water contained in the pumping filter 7 and the cooling air is turned into cooling air, which is discharged as cold air from the cold air outlet 4 through the inside of the fan case 10.

When the drive of the pumping filter 7 is stopped from the cold air operation state, the pumping filter 7 is kept in a dry state,
The outside air passes through the water pumping filter 7 without being cooled, and is discharged from the cold air outlet 4 through the inside of the fan case 10, thereby performing a blowing operation.

When the shielding plate 13 is closed from the air blowing operation state,
The air blowing from the cold air outlet 4 is blocked by the shielding plate 13, and the air blowing direction inside the fan case 10 is changed from the front toward the lower hot air sending duct 25 by the wind direction guide 22. The heater 24 is energized by the limit switch 26, and the air passing through the hot air delivery duct 25 is heated by the heater 24 and discharged as hot air from the hot air outlet 5, thereby performing hot air operation.

When the water pumping filter 7 is driven from the hot air operation state, the warm air is discharged from the hot air discharge port 5 in a humidified state, so that the humidified hot air operation is performed.

When the shielding plate 13 is opened from the humidified warm air operation state, the power supply to the heater 24 is cut off and the air outlet 12 is opened, so that the above-mentioned cold air operation is performed.

(Effects of the invention) This invention has a fan case with a built-in fan that sucks and blows the air passing through the pumping filter, and a shield plate is attached to the air outlet of this fan case so that it can be opened and closed.
