Abstract

PURPOSE:To continuously keep the drying capacity by bringing the spherical float having smaller specific gravity than that of water into contact with the inner surface of a water receiving port. CONSTITUTION:The moisture in the air is cooled by cooling fins 12, and dewed into water drops which are dropped from the lower top ends of fins. The water drops are accumulated in the large diameter part of the water receiving port 22, and, when the amount of accumulated water is increased, the buoyancy acts to the float 23 to raise the float 23, which generates a clearance between the float 23 and the water receiving port 22, and the water is discharged downward and accumulated in a water receiving pan 25. When the water is discharged from the water receiving port 22, the float 23 is lowered and the clearance is closed again to prevent the moisture from the outside from flowing reversely into the box body. Heat is generated in the heat radiation side 8b of the cooling element 8, and is transferred to heat radiation fins 11 through a heat transfer body 9 to radiate into the air. Thus, the drying state is continuously maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for drying the air inside a box by electronically cooling the air to form dew, frost, or ice.

[Conventional technology] Conventionally, in order to protect food, clothing, precision equipment, etc. from moisture, a drying agent such as raw coal or silica gel was packed in a breathable sheet in the container in which these items were stored. It is common to include This prevents deterioration of food, mold on clothing, and functional deterioration of precision equipment. [Problems to be Solved by the Invention] In the conventional drying means as described above, since a desiccant is used to dry the air inside the container, there is a limit to the drying ability, and the desiccant with reduced capacity There is a problem in that it has to be replaced again and again with a new one.

This invention was made to solve the above problems, and is an electronic drying device that can maintain drying performance semi-permanently, prevent backflow at the water socket, and improve drainage performance. [Means for Solving the Problems] An electronic drying device according to a first aspect of the present invention houses an electronic cooling element in a box body, and has cooling fins on the heat absorption side of the electronic drying device. A heat dissipation fin is fixed to the heat dissipation side, and a trumpet-shaped water socket is installed below the cooling fin to catch moisture dripping from the cooling fin and discharge it to the outside of the box, and a spherical float with a specific gravity smaller than water is installed on the inner surface of the water socket. are in contact with each other.

Further, an electronic drying device according to a second aspect of the present invention is the same as that of the first aspect, in which a float is not used and the inner surface of the water socket is subjected to hydrophobic treatment.

Further, in the electronic drying device according to the third aspect of the present invention, a water backflow preventing material is provided in the water socket, and a protective material having good water permeability and a dust removal function is placed above the material.

[Function] In the first aspect of the present invention, a spherical float having a specific gravity smaller than that of water is brought into contact with the inner surface of the water socket that receives water dripping from the cooling fins, so that the dripping water does not reach the water socket. When the water is stored, the float floats to the surface, creating a gap between it and the water inlet, allowing the water to be discharged. When the water is drained, the float lowers and the above gap is closed. Furthermore, in the second aspect of the present invention, since the inner surface of the water socket is subjected to hydrophobic treatment, falling water and ice are discharged without adhering to and remaining on the water socket. In addition, in the third aspect of the present invention, a water backflow prevention material is provided at the water socket, and a protective material with good water permeability and a dust removal function is placed above the material, so that dripped water can pass through, but dust can be removed. is prevented from passing through and does not adhere to the backflow prevention material.

The water inlet is made up of a large diameter part shaped like a trumpet that expands upwards, and a small diameter part shaped like a tube and tapered at the lower end. A spherical float (23) that functions as a preventive material is in contact with it. (24) is a plate plate fixed to the lower part of the outer surface of the box body (1), and (25) is a water socket (2) placed on the plate plate (24).

A power supply section (27) is attached to the outer surface and houses a power supply circuit (not shown). A cover (27) is attached to the outer surface of the box body (1) and surrounds the radiation fins (11) and the power supply section (26), with ventilation on the top surface. A mouth (27a) is bored and the lower part is open.

In the electronic drying device configured as described above, articles are stored in a dry state by operating as follows.

First, open the door (2) by rotating it downward and place the item in the box (1).
) in the storage room (1a). Then, the door (2) is closed by moving it upward eight times, and is latched to the box body (1) with the catch (6). Since the seals (4) and (5) are now in close contact with each other, ventilation inside and outside of the box body (1) is prevented.

Next, when this device is connected to an AC power source, rectified DC is supplied to the electromagnet (21) and the cooling element (8). By energizing the electromagnet (21), the movable rod (19) is attracted, the partition door (15) rotates around the hinge (16) and opens, and the storage room (1a) and the cooling room (14) communicate with each other. ．． On the other hand, by energizing the cooling element (8), its heat absorption side (8a
) occurs and the cooling fins (12) are cooled, so water vapor in the air condenses on its surface, and when the amount increases, it becomes water droplets and drips from the tip of the bottom. These water droplets are received by the water socket (22), but because there is a spherical float (23), the water accumulates in the large diameter part of the water socket (22). When this amount of stored water increases, buoyancy will eventually act on the float (23) and the float (23) will float up. This creates a gap between the float (23) and the water receptacle (22), so water is discharged downward and the water receptacle (22) is drained downward.
5). When the water is discharged from the water socket (22), the float (23) is lowered and the gap is closed again, preventing external moisture from flowing back into the box (1). In addition, the lower end of the water socket (22) is tapered, so water drains well. Although the water stored in the water tray (22) naturally evaporates, the water can also be discarded by pulling out the water tray (25) at a suitable time.

On the other hand, heat generation occurs on the heat radiation side (8b) of the cooling element (8), and this heat is transferred to the heat radiation fin (1) through the heat transfer body (9).
As described above, the air in the storage chamber (1a) is transmitted to the cooling fins (1a) and radiated into the air here.
By condensing in step 2), moisture is removed and a dry state is maintained.

In the example, dew condensation was caused by the cooling fin (I2), but the cooling fin (12) was cooled to 0°C or lower to form frost or ice on the surface of the cooling fin (12), and then the cooling By turning off the power to the element (8), it is also possible to melt frost and ice and cause water to drip. At this time, the electromagnet (21) is de-energized, the partition door (15) is moved eight times in the opposite direction by the force of the push spring (20), and the storage chamber (l) is moved eight times in the opposite direction.
a) and the cooling chamber (l4) are shut off. This prevents moisture that evaporates when the frost or ice on the cooling fins (12) melts from entering the storage chamber (la).

5 and 6 are enlarged vertical cross-sectional views of a water socket (22) showing another embodiment of the present invention. FIG. 31). The water that drips onto the hydrophobically treated surface (31) moves like a mercury ball, falls down the inner surface of the water socket (22), and is discharged. Since the hydrophobic treated surface (31) has weak adhesion to frost, ice, etc., frost and ice formation on the water socket (22) is prevented. In this way, residual moisture does not cause an increase in humidity, and the dehumidification efficiency of the device increases. Figure 6 shows the flow}- (23
), and the float (23) is also treated with hydrophobic treatment (
31), which also serves to prevent moisture from flowing back. 7 and 8 are also enlarged vertical cross-sectional views of the water socket (22) showing other embodiments of the present invention, and FIG.
A protective plate (32) with good water permeability and a dust removal function is provided on the top of the float (23) of 22).The protective plate (32) easily allows drainage from above to pass through, but does not block dust. I will. This prevents dust from adhering to the float (23), eliminates clogging, poor sealing, etc., and maintains the function of the float (23) to prevent backflow of moisture. In Fig. 8, instead of the float (23), a backflow prevention material (33) made of a polymeric material with good water permeability is inserted into the small diameter part of the water socket (22).
The protective material (32) prevents dust from adhering to the backflow prevention material (33). Note that the protective material (32) is easy to attach and detach, and if it becomes dirty, it can be removed and washed with water.

[Effects of the Invention] As explained above, in the first aspect of the present invention, an electronic cooling element is housed in a box body, and cooling fins are provided on the heat absorption side of the electronic cooling element.
A heat dissipation fin is fixed to the heat dissipation side, and a trumpet-shaped water socket is provided below the cooling fin to receive water dripping from the cooling fin and discharged to the outside of the box, and a spherical float with a specific gravity smaller than that of water is installed on the inner surface of the water socket. When the dripping water accumulates in the water socket, the float floats to the surface and the water is discharged, and when the water is discharged, the float lowers and closes the gap, maintaining drying capacity semi-permanently and efficiently. This has the effect of being able to construct a drying device that lasts for a long time, and also being able to prevent moisture from entering from outside through the water socket.

In addition, in the second aspect of the present invention, since hydrophobic treatment is applied to the inner surface of the water socket, fallen water and ice are discharged without adhering to and remaining on the water socket, thereby preventing an increase in humidity due to residual moisture. This has the effect of increasing dehumidification efficiency. In addition, in the third aspect of the present invention, a water backflow prevention material is provided at the water socket, and a protective material is placed above it, so that dripping water passes through but dust is prevented from passing, and the drainage function is improved. This has the effect of sufficiently maintaining the backflow prevention function.
