Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a hot air/cold air generator.

[Prior art and its problems] For example, in strawberry cultivation, a method is used in which seedlings in a nursery are separated and transplanted to the flat bed of a greenhouse.
In this case, if the seedlings in the nursery are cooled before being separated and transplanted, they will immediately grow larger when separated and transplanted, so the inside of the nursery house is cooled with a cooling device.

Conventionally, this type of cooling device has used a refrigerator using a refrigerant. Although this cooling device is effective in shortening the strawberry cultivation period, it is expensive because it requires a compressor and a motor to operate it. In addition, this cooling device is expensive to purchase and has a short period of use, and strawberry farmers generally cannot purchase it because it increases the cost of strawberries.

[Purpose of the invention] An object of the invention is to provide a hot air/cold air generating device that is low in cost and has substantially the same efficiency as a conventional cooling device.

[Structure of the device] The present invention includes: a partition body provided in a housing; a heat exchange chamber and a dripping chamber formed by the partition body and partially communicating with each other; an outside air intake communicating with the heat exchange chamber. A fan that introduces outside air into the heat exchange room; A water sprinkler installed in the heat exchange room; An air supply port installed on the wall of the dripping chamber; This hot air/cold air generator is equipped with a drip removal tube that sends air; a blow tube that sends heat-exchanged air from an air outlet to the outside of the housing;

The partition body is generally installed vertically downward from the upper wall within the housing, but other structures may be used as long as a heat exchange chamber and a drip removal chamber can be formed. The heat exchange chamber and the dripping chamber are communicated with each other directly or through other members. Although the fan is generally installed at the outside air inlet, it can also be installed on the way from the outside air inlet to the air inlet or at the air inlet.

In the present invention, the drip removal cylinder is made to protrude into the drip removal chamber. Although the reason is not clear, when the drip removal tube protrudes into the drip removal chamber, water droplets are no longer discharged from the air supply port. The longer the protruding length of the drip removal tube, the better the drip removal effect. However, on the other hand, the amount of air discharged from the air supply port decreases, and the discharge pressure also decreases.

On the contrary, the shorter the protrusion length, the greater the amount of air that enters from the air supply port and the stronger the discharge pressure. However, water droplets are discharged from the air outlet.
Therefore, the protrusion length in order to achieve harmony between the two is 1cm~
It is between 5 cm, preferably between 2 cm and 4 cm.

The drip removal cylinder and the sending cylinder can be provided by inserting a single cylinder into the air inlet, or can be provided by attaching respective cylinders to the periphery of the air inlet.

[Function] Sprays water from the water spray body and exchanges heat with the introduced air. The heat-exchanged air is sent to a drip removal chamber and sent to a house etc. by a blower.

Note that in winter, the temperature of groundwater is higher than the outside air, so the above device can also be used as a hot air generator. It can also be used as a hot air generator by using boiled water.

Furthermore, a temperature sensor can be installed at a place where cold air or hot air is sent, such as inside the house, and the temperature sensor can be used to start and stop the fan, thereby adjusting the temperature inside the house.

[Example] The present invention will be described in more detail based on an example shown in the drawings. FIG. 1 is a partially cutaway schematic perspective view of one embodiment, and FIG. 2 is a schematic diagram showing the state of use.

On both sides of the interior of the housing 1, partition walls 2 and 2a are vertically disposed from a ceiling wall 10 of the housing 1. The lower ends of the partition walls 2, 2a are located slightly above the bottom 11. The inside of the housing 1 is partitioned by the partition walls 2, 2a, and a heat exchange chamber 3 is formed in the center, and dripping chambers 4, 4a are formed on both sides of the heat exchange chamber 3. The heat exchange chamber 3 and the drip removal chambers 4, 4a communicate with each other at the lower ends of the partition walls 2, 2a. Among the side walls 40, 40a,
A drain pot 12 is provided at the bottom 11, and a water level adjustment pot 13 is provided slightly above it.

A ceiling wall 10 of the housing 1 is provided with an outside air inlet 5 and communicates with the heat exchange chamber 3. A fan 6 for introducing outside air into the heat exchange chamber 3 is provided above the outside air inlet 5 and is driven by a motor M.

A water sprinkler 7 is installed in the center of the heat exchange chamber 3 in the height direction.
has been installed. The water spray body 7 forms a rectangular frame 70 using pipes, and has two opposing sides 71, 7.
In this structure, an appropriate number of intermediate pipes 73 are installed between the two to allow air to easily pass therethrough, and an appropriate number of water spray holes 74 are provided on the lower surfaces of the framework 70 and the intermediate pipes 73.
The pipes on the two opposing sides 71 and 72 have a larger diameter than the other pipes, and serve as a water tank. Note that each pipe is connected to each other, and since air can easily pass through the water spray body 7, no load is placed on the fan.

Air supply ports 41 and 41a are provided through the side walls 40 and 40a of the drip removal chambers 4 and 4a at two locations in the horizontal direction, respectively. The cylinder 8 is inserted through the air supply ports 41 and 41a and is fixed thereto. A portion of the cylindrical body 8 that projects about 3 cm into the drip removal chambers 4 and 4a serves as a drip removal cylinder 9.

Further, a portion protruding from the air supply ports 41, 41a to the outside of the housing 1 serves as a supply cylinder 90.

[Function] A hot air/cold air generating device is installed inside or outside the house, and an aeration pipe 100 is installed inside the house. Next, the pumped up groundwater is injected into the water sprinkler body 7 from the water pipe 101, and water is sprinkled in a shower form from the water sprinkling holes 74 provided in the water sprinkler body 7. Next, the motor M is activated to rotate the fan 6, and outside air is introduced into the heat exchange chamber 3 through the outside air introduction port 5. The introduced outside air passes through the cooling water shower and is blown against the cooling water accumulated in the bottom 11 to perform heat exchange, create cold air, and is introduced into the drip removal chambers 4 and 4a, and is then passed through the air supply port. 41,41
Air is sent to the diffuser pipe 100 from a. At that time, the cold air containing a large amount of moisture is transferred to the side wall 4 as shown by the arrow.
0, 40a and the partition walls 2, 2a to form dew condensation and reduce the amount of moisture.

A large number of exhaust ports 102 are provided in the air diffuser pipe 100, and cold air is discharged throughout the house from the exhaust ports 102. Note that if the water level adjustment pot 13 is opened, the water level in the housing 1 will not exceed a certain level, and water overflow can be prevented.

The present invention is not limited to the illustrated embodiment, but can be modified in many ways within the scope of the claims of the utility model registration.

[Effect of the idea] The present invention has the above configuration and produces the following effects.

(a) A heat exchange chamber is formed by a partition wall installed in the housing, and outside air is applied to the water being sprinkled from a sprinkler body installed in the heat exchange chamber to exchange heat and produce cold or warm air. The air can be discharged from the housing through the air inlet. In this way, a compressor and associated equipment are unnecessary to generate cold air or hot air, and the structure is simple, so this hot air/cold air generator has almost the same effect as a conventional cooling device at a low cost. can be provided.

(b) When outside air is applied to the water being sprinkled through the outside air inlet to exchange heat, the heat-exchanged air contains a large amount of moisture. If this is discharged as is, it may cause rust on other attached equipment or cause water droplets to be discharged into the greenhouse. However, in the present invention, a drip removal chamber is formed, and a drip removal cylinder that sends heat-exchanged air to the air outlet is installed protruding inside the drip removal chamber, so that almost no water droplets are discharged from the air outlet. Not done.

Therefore, there is no possibility of rust on other attached equipment or water droplets being discharged into the house.
