Abstract

PURPOSE:To enhance the evaporating performance of defrosted water in an evaporation tray by extremely simple means by employing the tray made of a water absorption material with a water absorption plate. CONSTITUTION:Cylindrical body 10a is raised in series on the bottom of an evaporation tray 10, its inside is formed with duct holes (a) for passing rising hot air from a compressor 3 and its outside is formed with a defrosted water reservoir (b) discharged annularly. A lower end 11a of a caplike water absorption plate 11 formed of a material made by compressively coupling porous ceramics, foamable plastic of continuous foams or fibers is brought into contact with the inner bottom in the reservoir (b) in a mounting state, and many air flow holes (c) for passing rising hot air passing the holes (a) are provided at a central top wall 11b. The defrosted water in the reservoir (b) from the lower end 11a is sucked by capillary to the plate 11 so that the entirety becomes wet. On the other hand, rising hot air from the compressor 3 rises in the holes (a), and passes the holes (c) while direct contact with the wall 11b of the plate 11. In this case, since the hot air is brought into direct contact with water content in the plate 1, it is heated to enhance the evaporating effect of the water content in the plate 11.

[Problem to be solved by the invention]

Conventional defrost water evaporators such as Refrigerator
Since the water in the evaporating dish is heated indirectly, the efficiency is low and the amount of evaporation is small, so there is a problem that it cannot be applied to large refrigerators and the like.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to obtain a defrost water evaporator with good defrost evaporation performance.

[Means to solve the problem]

In the defrosting water evaporator for refrigerators, etc. according to the present invention, the first
As an invention, there is provided a cylindrical body (10a) that forms a duct hole (holes inside and outside) and a water reservoir (b) on the inner bottom surface of the evaporating dish attO.
A cap-shaped water absorbing plate aυ whose lower end is immersed in the water in the water reservoir (b) is fitted onto the cylindrical body (10a), and the center top of this water absorbing plate is raised in a series. The wall portion (11'b) has all air circulation holes (c).

Furthermore, in the case of invention W.2, the entire evaporating dish H is made of water-absorbing material, including the cap-like body (101) that is raised in series from the inner bottom surface, and the duct hole (A) inside the center is made of a water-absorbing material. A waterproof coating layer azt is formed on the other outer surfaces so as to leave an air circulation hole (c) in the central top wall of the communicating cap-like body (1ob).

[Effect]

In the case of this invention, the defrosting water that has permeated the water absorbing plate or water absorbing evaporating dish is evaporated by direct heating with warm air rising from the compressor.

〔Example〕

Hereinafter, one embodiment of invention #g1 of this invention will be described with reference to FIGS. 1 and 2. That is, in these figures, (1) to 4) are exactly the same as the conventional device in the He diagram.QO is the evaporating dish in the device of this invention;
A cylindrical body (10a) is raised in series on the inner bottom surface, and there is a duct hole (a) on the inside of the hood for passing the rising warm air from the compressor (3), and a duct hole (a) for passing the rising warm air from the compressor (3), and the outside for exhaust. A water reservoir (b) for defrosting water is formed in an annular shape. αB is a cap-shaped water absorbing plate made of porous ceramic, open-cell foamed plastic, or fibers compressed and made of the following materials.
Its lower end (11a) abuts against the inner bottom surface of the water reservoir (b) in the installed state, and the central top wall (11b) contains a large amount of air that passes through the rising warm air through the duct hole (a). It has a distribution hole (c).

Since the water absorbing plate allK is constructed as described above, the defrosting water in the water reservoir (b) is absorbed from the lower end (Ha) of the water absorbing plate allK by capillary action, and the entire surface becomes wet.

On the other hand, the rising warm air from the compressor (3) rises inside the duct hole (A) and directly touches the central top wall (11b) of the above-mentioned water absorption plate αD, which is in a moist state, while the air circulation hole in the core ( C)
going through. At this time, the warm air directly contacts the moisture in the water absorbing plate αD, so that the heating is not only carried out effectively, but also because there is a slight wind speed, the effect of evaporating the moisture in the water absorbing plate al is enhanced.

FIGS. 3 and 4 show another embodiment of the invention described in g1 above, in which the water absorbing plate αD is provided slightly away from the upper surface of the duct hole provided in the evaporating plate αG.

This allows the warm air that rises inside the duct hole (A) to spread outward, creating a wider evaporation surface.

Further, FIG. 5 shows a second invention of the present invention, in which a cap-like body (tab) is provided on the inner bottom surface of the evaporating dish αG.
are raised in a series, with a duct hole (a) similar to the one above formed on the inside, and a similar water reservoir (b) formed on the outside.
Furthermore, the central top wall part has a large number of air circulation holes (c) for the rising warm air passing through the duct holes (a), and in particular, the whole is made of water-absorbing material, and the air circulation holes ( It is characterized in that a waterproof coating layer αz'jk is formed on the other outer surfaces except for c).

〔Effect of the invention〕

Since the defrosting water evaporation device for refrigerators, etc. of this invention is constructed as described above, the evaporation performance of the defrosting water in the evaporating dish can be maximized by using a water absorbing plate and an evaporating dish made of a water absorbing material. The effect is that it can be increased with simple means.
