BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a subcontroller for a thawing machine, and more particularly, to a subcirculating microwave using a low-frequency microwave that is lower than a frequency used in a conventional microwave oven, It was invented so that the food can be quickly cooked evenly in a natural state in a short time.

In general, various methods have been studied for solving problems such as quality, productivity, and cost during thawing at home and abroad. One of them is the most interested in thawing method using microwaves.

Conventional thawing methods up to now raise the temperature first from the surface of the food in contact with the outside air, and the heat is transferred to the inside of the frozen food by the heat conduction of the elevated temperature, and the whole thawing is performed.

However, when the microwave is used, the kinetic energy is changed into thermal energy in the entire portion where the microwave penetrates, so that the inside and the outside of the frozen food are simultaneously heated within a short time, There is an advantage.

A microwave is irradiated to the frozen food through a waveguide using a 2,450 MHz microwave generating magnetron used in a general microwave oven. To this end, a high voltage transformer for controlling the input power, an air cooling fan for cooling, and a noise filter are additionally attached .

Korea Patent Registration No. 10-0621718 (Registration date August 31, 2006) Korean Patent Publication No. 10-2008-0098468 (published on November 10, 2008)

On the other hand, using this principle, a small amount of frozen food was thawed in a microwave oven which is partially used at home.

However, in the conventional commercial microwave oven, the frequency of the microwave of 2,450 MHz is relatively high and the wavelength length is as short as 12.2 cm. Since the microwave is not developed for thawing of food, when the size of the food is large or the throughput is large, There is a problem that it is difficult to thaw and there is a problem that it is difficult to obtain a uniform thawing result.

An object of the present invention is to provide a microwave oven capable of realizing uniform thawing within a short period of time irrespective of the size of a food or the processing capacity by distributing microwaves most uniformly to the inner space of a defrosting chamber by using a low frequency microwave And to provide motivation of the machine.

Another object of the present invention is to provide a sub-moter of a thawing machine which is capable of processing a necessary amount at a necessary point in time.

It is another object of the present invention to provide a submerged motive power of a thawing machine that can reduce the loss of raw materials and improve the quality by minimizing the weight change due to drip during thawing, thereby enhancing the reliability and merchantability of the product.

It is still another object of the present invention to provide a submerging motor for a thawing machine capable of minimizing the discharge of polluted water and wastewater and minimizing the deterioration of the thawing water.

In order to achieve the above-mentioned object, the present invention provides an image forming apparatus including a frame (10) enclosing the outside by covers (11)

A defrost chamber 20 in which the inlet is closed by the door 1 at the inside of the frame 10 and the microwave inflow passage 21 is opened at one side,

The microwave generator 35 for microwave generation and irradiation is fixed by the control circuit so that the inlet passage 21 and the outlet passage 31 of the defroster chamber 20 coincide with each other, (30)

(40) provided for scattering the microwaves to the inside of the thawing chamber (20) and rotated by driving the motor (44)

The sub-motors 40 are formed by integrally bending the blades 42 inclined at a predetermined inclination angle A at both ends of the horizontal plates 41 horizontally divided into four directions from the center.

The inclination angle A of the blade 42 of the sub-synchronizer 40 is set to 30 degrees with respect to the horizontal line.

According to the present invention, uniform thawing can be realized within a short time, regardless of the size of the food or the processing capacity, and a necessary amount can be processed at a necessary point in time.

In addition, the discharge of polluted water and wastewater can be minimized, and the deterioration of the thawing water can be minimized, thereby enhancing the reliability and merchantability of the product.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the microwave generated by the microwave generator 35 of the present invention is set at a low frequency relative to the conventional microwave frequency of 915 MHz.

The 915 MHz microwave has a wavelength of 32.7 to 33 cm in the air and a longer wavelength than the frequency (12.2 cm) used in a microwave oven.

Therefore, even when the material is thick in the process of defrosting the frozen food, it is revealed that the wave is transmitted deeply and the defrosting effect can be greatly improved.

The frame 10 forms a frame of the defrosting machine, and various structures and components to be described later are fixedly installed, and then the cover 11 is wrapped around the frame.

The thawing chamber 20 is fixed in position on the inside of the frame 10 in the form of a hollow rectangular housing which is forwardly folded and the front entrance is opened and closed by the door 1 so that the food materials can be moved into and out of the inner space do.

The door 1 has a rectangular protruding portion 2 protruding toward the inside and a receiving space 3 for accommodating the rectangular protruding portion 2 is provided at the entrance of the defrosting chamber 20.

The microwave inflow passage 21 is formed at one side of the upper surface of the thawing chamber 20 so that the outlet passage 31 of the waveguide 30 coincides with the inflow passage 21, The waveguide 30 is fixed in position.

The microwave generator 35 is positioned and fixed to the position of the hole 32 drilled in the upper portion of the waveguide 30 so that the microwave is irradiated into the waveguide 30 through the hole 32.

As the microwave generator 35 of the present invention, a magnetron is employed.

The waveguide (30) has a hollow trapezoidal shape and is installed and fixed so as to communicate with the inside of the defrosting chamber (20) in a state where the outlet passage (31) is opened at the bottom.

Therefore, when the microwave generator 35 is operated through the power supply unit and the control circuit, the low frequency waves are radiated into the defrosting chamber 20 through the inside of the waveguide 30 to defrost the frozen food material.

Inside the defrosting chamber 20, there is provided a sub-motor 40 which is rotated by driving of a motor 44 so that microwaves scatter and fluctuate so that microwaves supplied to the material can be transmitted more effectively.

Here, since the sub-motors 40 interfere with the effect that the microwaves are transmitted to the interior of the defrosting chamber 20 according to their shapes and positions, they greatly affect the overall performance of the defrosting machines.

The sub-synchronizer 40 of the present invention is constituted such that the metal plate material of a certain thickness is formed in a "+" shape horizontally in four directions by horizontally forming the horizontal plates 41, 42 are integrally bent and formed.

The microwave is reflected by the horizontal plate 41 and the sloped blades 42 while the sub-synchronizer 40 is rotated at a constant speed by the power of the motor 44 so that the microwave is most evenly distributed to the inner space of the defroster chamber 20 So that it can perform a small fluctuation role.

The inner bottom of the defrosting chamber 20 may be provided with a support plate for rotating the material so that the material is uniformly defrosted and a rotating means for rotating the defrost plate.

According to the thawing machine of the present invention, it is possible to prevent irrationality such that the thawing progresses partially or the microwave concentrates only at a specific position.

Therefore, the temperature of the food material to be thawed can be made uniform, and thawed in a natural state just before freezing.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

The present invention applies to thawing technology. In particular, the present invention is applied to a thawing machine using a microwave, which allows a frozen food to be thawed almost evenly in a short time and cooked immediately.
