Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cool air blower using a condenser and an evaporator, which can obtain the function of a warm air blower without switching a refrigerant circuit.

[Conventional technology]

BACKGROUND ART There is known a cool air blower in which a condenser and an evaporator are mounted in a frame body, and cold air obtained by passing through the evaporator blows out from the front surface of the frame body to form a spot killer. In order to use this cold air blower even in winter, a cold air hot air blower, which is now equipped with a ceramic heater and is heated by the hot air obtained by heating the ceramic heater, has been put into practical use.

[Problems to be solved by the device]

By the way, a ceramic heater, which is an electric heating element, can generate a larger amount of heat than a conventional metal heating element such as a nichrome wire, but it has an electric capacity of about 1000 KW, which is the amount of air discharged for a warm air heater. Could not be large, the heating effect was unsatisfactory.

Also, in a large air conditioner such as a separate air conditioner, there is an air conditioner that switches the refrigerant circuit with a four-way valve to switch between the condenser and the evaporator, but the four-way valve used for the refrigerant circuit is extremely expensive, In addition, the condenser and the evaporator are required to have a complex structure that can be used for both purposes, and it was impossible to apply them to an inexpensive cold air blower of about 500 Kcal / h.

[Means for improving problems]

This invention relates to a cool air hot air blower that can obtain warm air even in a cooling cycle by specifying the shape of the frame and the arrangement of parts. 1 is a frame, 2 is a partition that divides the inside of the frame 1 into two chambers, left and right. The plates 5 are biaxial motors attached to the partition plate 2, and suction fans 3 and 4 are attached to drive shafts protruding from the motor 5, respectively. 6 is a condenser mounted on the side of the frame 1 facing the suction fan 3, and 7 is an evaporator mounted on the side of the frame 1 facing the suction fan 4 on the opposite side. Discharge ports 3'and 4'are mounted side by side toward the front of the frame 1.

Reference numeral 8 denotes a blower port provided in front of the frame body 1 in front of the discharge ports 3 ', 4', 9 denotes exhaust chambers formed in the frame body 1 on both sides of the blower port 8, and the exhaust chambers 9 on both sides are It communicates with the lower part of the blower port 8 and further communicates with an exhaust port 12 provided on the back surface of the frame 1. 10/11
Is a damper which is attached with the end of the blower port 8 facing the discharge ports 3 ', 4'as a spindle, the dampers 10, 11 swing together, and the tip end of the blower port 8 in the discharge ports 3', 4 '. I am looking into. Therefore, the dampers 10 and 11 are connected to the suction fan 3 on the condenser 6 side.
The hot air obtained from the condenser 6 is blown forward from the blower port 8 while the cool air obtained from the evaporator 7 passes through the exhaust chamber 9 and is exhausted to the rear of the frame body 1. Ejected through mouth 12.

[Explanation of action]

When the compressor (not shown) is operated in this invention having the above configuration, the refrigerant is compressed and sent to the condenser 6, and the temperature of the air passing through the condenser 6 becomes high and the refrigerant is liquefied. The liquefied refrigerant is vaporized in the evaporator 7 through the capillary, the air passing through the evaporator 7 becomes low temperature, while the refrigerant exiting the evaporator 7 is pressurized again in the compressor, and the cooling cycle is operated. To do.

In this invention, a condenser 6 and an evaporator 7 are arranged on both sides of a frame body 1, and a suction fan 3 and
When 4 is driven, the air that has passed through the condenser 6 and the evaporator 7 is blown out forward from the discharge ports 3'and 4 '.

On the other hand, a blower port 8 is provided in front of the discharge ports 3 ', 4'of the frame body 1, and dampers 10, 11 for connecting the blower port 8 and one of the discharge ports 3', 4'are provided. By driving the dampers 10 and 11, one of the discharge ports 3'and 4'can be selected and connected to the blower port 8. Further, exhaust chambers 9 are provided in the frame body 1 on both sides of the blower port 8 so that one discharge port which is not connected to the blower port 8 communicates with each other.
The exhaust gas sent to is directly discharged from the side of the frame 1 as it is, or is discharged from the back of the frame 1 via the flow path.

Therefore, a damper that is linked by an operation knob (not shown)
If you operate 10/11, the air blown from the blower opening 8
It becomes possible to switch between 3'and 4 ', and desired hot and cold air can be blown from the blower opening 8.

[Explanation of effects]

With the component arrangement structure as described above, the operator can arbitrarily operate the dampers 10 and 11. By this damper operation, the wind blown from the blower port 8 can be the same as the wind that has passed through the condenser 6. The wind that has passed through the evaporator 7 can be selected.

Further, the air blown from the discharge port not connected to the blower port 8 is sent to the exhaust chambers 9 provided on both sides of the blower port 8 and discharged in a direction different from that of the blower port 8. In the structure in which one exhaust port 12 is provided on the back surface of the frame 1 as described above, when hot air is desired, cold air is discharged, and when cold air is desired, hot air is discharged, and the exhaust duct is used. If it can be discharged directly to the outside of the room, the cold air effect and the warm air effect are improved.

Also, in this invention, in order to obtain warm air, the complicated structure such as switching the ceramic heater and the refrigerant circuit with a four-way valve is unnecessary, and since warm air is obtained only by mechanical damper operation, it is cheaper than conventional products. It was possible to obtain an extremely practical cold-air warm air blower that can be manufactured in a simple manner and that has a large amount of heat generation per amount of power used to improve efficiency.
