Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a steam heater that heats and thaws frozen foods and cooks foods using generated steam. This reduces the amount of steam exhausted into the equipment installation room by condensing the exhausted steam.

[Prior Art and Problems] This type of steam heater has a structure as shown in FIG. 5, for example.

In this system, a heating water tank 2 equipped with a heater 3 is installed at the bottom of the refrigerator interior 1, and a water supply pipe 6 is connected to the heating water tank 2.
is installed through it.

When the mesh baskets 4, 4 containing frozen food A are placed in the chamber 1 and the heater 3 of the heating water tank 2 is energized, the water placed in the heating water tank 2 is heated and evaporated, and the chamber 1 is filled with steam. . The steam generated in the refrigerator interior 1 is stirred by a fan 8, and the frozen food A in the mesh basket 4 is heated and thawed.

On the other hand, steam is being generated one after another from the heating water tank 2, and the interior of the refrigerator 1 becomes in a state of excess steam, so this excess steam is discharged to the outside from the exhaust pipe 5 installed through the upper wall of the interior of the refrigerator 1. That's what happens.

However, the conventional steam heater described above has a problem in that a large amount of steam is exhausted into the room in which the appliance is installed, which abnormally increases the humidity in the room.

This is because the excess steam in the chamber 1 is exhausted while remaining in the steam state.

[Technical Problem] The present invention is a steam heater that heats food using steam generated inside the refrigerator and sequentially exhausts excess steam to the outside of the refrigerator. In order to reduce the amount of steam, the objective is to convert the exhausted steam into water so that it can be drained.

[Technical Means] The technical means of the present invention for solving the above problem is to provide a spray chamber equipped with a cold water spray nozzle in the steam exhaust passage, and branch a drain pipe to the lower side of the spray chamber. This is because the piping was installed.

[Effect] The above technical means works as follows.

Excess steam in the refrigerator interior 1 is exhausted through the exhaust passage, similar to the conventional system described above. and,
This exhausted steam enters the spray chamber in the exhaust passage,
Receive cold water spray from cold water spray nozzle.

Then, when the exhausted steam is cooled by spraying cold water, the steam condenses and changes its state to water.

Thereafter, this state-changed water is drained out of the appliance from a drain pipe branched below the spray chamber.

[effect] The present invention has the following unique effects.

Since the exhausted steam can be turned into water and drained, the amount of steam exhausted from the exhaust stack 5 can be reduced, and problems such as abnormally high indoor humidity can be prevented.

[Example] Next, an example of the present invention described above will be described in detail with reference to the drawings.

The steam heater according to the embodiment of the present invention shown in FIG.
A spray chamber 7 is provided outside the side wall of the chamber interior 1, through which the exhausted steam passes.

The chamber interior 1 and the spray chamber 7 communicate with each other through through holes 11, 11 formed in the side walls of the chamber interior 1, and the steam flow is guided to the spray chamber 7 side of the through holes 11, 11. A guide plate 72 is provided. Also, spray chamber 7
A drain pipe 71 is connected to the bottom of the spray chamber 7, and an exhaust pipe 5 leading to the outside of the device is connected to the upper wall of the spray chamber 7.
are installed in succession.

A cold water spray nozzle 9 is disposed within the spray chamber 7, and the tip of the cold water spray nozzle 9 faces toward the drain pipe 71. (See FIG. 2) Further, the steam stirring fan 8, the heating water tank 2, the heater 3, etc. are constructed in the same manner as the conventional ones described above.

Now, the steam heated by the heater 3 and generated from the heating water tank 2 fills the interior 1 of the refrigerator 1 and heats and thaws the frozen foods A and A, as in the conventional case described above.

Next, the excess steam in the refrigerator enters the spray chamber 7 through the through holes 11, 11 drilled in the side walls of the refrigerator interior 1, and is further guided by a guide plate 72 and guided directly below the cold water spray nozzle 9. It will be destroyed. Then, the cold water spray nozzle 9 disposed in the spray chamber 7 sprays a mist of cold water onto the steam guided directly below the cold water spray nozzle 9, thereby cooling the steam. This will result in condensation.

Thereafter, water generated by the condensation of the steam is drained to the outside of the device from a drain pipe 71 installed at the bottom of the spray chamber 7.

Further, if there is steam that has not condensed even by the above-mentioned spraying of cold water, the steam is exhausted to the outside of the appliance from the exhaust pipe 5 in the same manner as in the conventional device described above.

Next, FIG. 3 shows a second embodiment of the present invention.
In this case, a part of the water supply pipe 6 is guided into the upstream exhaust passage of the cold water spray nozzle 9, and this part of the water supply pipe 6 is wound into a coil shape.

In this system, the exhausted steam is cooled by contacting the coiled winding portion of the water supply pipe 6, and then further cooled by the cold water spray nozzle 9. Therefore, there is an advantage that the exhausted steam is more likely to form dew condensation than when only the cold water spray nozzle 9 is used.

In each of the above embodiments, a propeller fan is used as the fan 8, but a Sirotskov fan may also be used as shown in FIG.

That is, a concave part 13 is provided in the back wall of the refrigerator interior 1, a blower blade 14 of a Shirotsko fan is attached to the concave part 13, and the opening of the concave part 13 is filled with a punching metal 16.
covered with. And in this one, the blower blade 1
A heater 15 is disposed around the outer periphery of the refrigerator 4 to further heat the steam in the refrigerator 1 to increase the efficiency of heating the food.

Furthermore, it goes without saying that the present invention can be used not only as a thawing machine for frozen foods, but also as a heater for steaming foods.
