Description

TECHNICAL FIELD

[0001] The utility model relates to a thawing device, in particular to an ohm thawing device. BACKGROUND

[0002] The current common thawing method of frozen food can only heat or exchange heat on the surface of the food, and the food is not thawed uniformly and the thawing speed is slow. The ohm thawing method directly converts electric energy into heat energy by using the electric conductivity of the food, and simultaneously heats the inside and outside of the food, which has the advantages of uniform heating, high energy utilization rate and short heating time.

[0003] Although the ohm thawing method has many advantages, in actual application, a large amount of heat is easily generated at the contact position of the electrode plate and the food due to the existence of contact resistance, which causes damage to the quality of the food. The temperature at the contact position of the electrode plate and the food in the ohm thawing method is too high, which also causes the degree of electrochemical corrosion of the food to increase, and the food and the electrode plate are easily contaminated; the contact position of the food and the electrode plate in the ohm thawing method is easily overheated, which causes the surface of the food at this position to be cooked, affecting the quality of the food.

[0008] The two electrode plate assemblies and the insulation module form an integral flat plate structure.

[0009] Preferably, the upper surface of the electrode plate assembly is provided with a concave-convex component.

[0010] Preferably, the lower surface of the electrode plate assembly is in the shape of a fin.

[0011] Preferably, the insulation module is provided with a groove portion, and the upper surface of the groove portion is lower than the upper surface of the electrode plate assembly.

[0017] Preferably, a fan is arranged above the drawer.

[0018] The positive progress effect of the present utility model lies in that the ohmic thawing electrode plate and the refrigerator drawer with the ohmic thawing plate set two electrode plate assemblies connected with different electrodes on the same plane, increase the application scenarios of the ohmic thawing electrode plate, and increase the surface area of the electrode plate assembly by setting the concave-convex component on the upper surface of the electrode plate assembly, thereby reducing the contact area of the food, reducing the area of the contact between the electrode plate assembly and the food, increasing the heat conduction speed, reducing the heat at the contact, avoiding the damage to the quality of the food, and the fin-shaped lower surface can better dissipate heat.

[0019] Figure 1 It is a schematic view of the refrigerator drawer with the ohmic thawing plate according to an embodiment of the present utility model. DETAILED DESCRIPTION

[0020] The present utility model will be described more clearly and completely by taking a preferred embodiment and combining with the drawings.

[0021] Embodiment 1

[0022] The present embodiment discloses an ohmic thawing electrode plate, which comprises two spaced-apart electrode plate assemblies 1 and an insulating module 2 arranged between the electrode plate assemblies 1, as shown in the figure. Figure 1 The two electrode plate assemblies 1 and the insulating module 2 form an integral flat plate structure.

[0023] The insulating module 2 is used to separate the two electrode plate assemblies 1, and the two electrode plate assemblies comprise conductive materials and are respectively connected with opposite electrodes.

[0024] The integral flat plate structure makes the ohmic thawing electrode plate applicable to various occasions, such as the bottom surface of a refrigerator freezing chamber or fresh-keeping chamber, or the bottom surface of a drawer in the freezing chamber or fresh-keeping chamber. As long as the food 100 is placed on the electrode plate, the part of the food 100 respectively contacts the parts of the two spaced-apart electrode plate assemblies 1, so that the food can be heated and thawed.

[0025] The electrode plate assembly 1 is made of electrically conductive material with high thermal conductivity, and the insulating module 2 is made of insulating plastic. The insulating module 2 is provided with a groove portion 21, and the upper surface of the groove portion 21 is lower than the upper surface of the electrode plate assembly, so that the juice produced during thawing of food can flow into the groove portion 21. Thus, the juice is prevented from remaining on the electrode plate assembly, affecting the heating effect on the food. On the other hand, the juice is also prevented from soaking the food for a long time, affecting the quality of the food.

[0026] Further, the length of the groove portion 21 is arranged along the length direction of the insulating module.

[0027] Further, the upper surface of the electrode plate assembly is provided with a concave-convex component 11, so that the surface of the electrode plate assembly is increased, the heat conduction speed is fast, the heat at the contact position between the electrode plate and the food can be quickly transmitted to the outside, the heat at the contact position is reduced, the temperature is reduced, and at the same time, the contact area between the food and the electrode plate assembly can be reduced, avoiding damage to the quality of the food.

[0028] Further, the concave-convex component is a sawtooth-shaped component. The sawtooth-shaped component can penetrate the food material, further reducing the contact area with the food, ensuring that the food is in close contact with the electrode, reducing the contact resistance, further reducing the heat generated at the contact position, and also fixing the food to prevent movement.

[0029] As another embodiment, the lower surface of the electrode plate assembly 1 is in the shape of fins 12. Further heat dissipation can be achieved, reducing the heat generated at the contact position between the electrode plate assembly and the food, and avoiding damage to the quality of the food.

[0030] The ohmic thawing electrode plate of this embodiment arranges two electrode plate assemblies connected to different electrodes on the same plane, increasing the application scenarios of the ohmic thawing electrode plate, and increases the surface area of the electrode plate assembly by arranging a concave-convex component on the upper surface of the electrode plate assembly, thereby reducing the contact area with the food, reducing the heat conduction speed, reducing the heat at the contact position, avoiding damage to the quality of the food, and the fin-shaped lower surface can better dissipate heat. The insulating module in the middle not only separates the two electrode plate assemblies, but also prevents the accumulation of juice.

[0031] Embodiment 2

[0032] This embodiment provides a refrigerator drawer, which is a refrigerator refrigerator and / or freezer drawer, and the drawer comprises the ohmic thawing electrode plate as described in Embodiment 1. As shown in Figure 1 .

[0033] The refrigerator drawer comprises a shell 10, a guide rail 30 at the bottom of the shell 10, a drawer body 20 arranged above the guide rail 30, and the bottom surface of the drawer body 20 is the ohmic thawing electrode plate of the embodiment 1. The drawer body 20 can slide along the guide rail 30 to open or close. A fan can be arranged above the drawer to blow air to the food and the ohmic thawing electrode plate, accelerate the heat exchange between the food, the electrode plate and the outside world, reduce the temperature of the contact position between the electrode plate assembly and the food, and accelerate the thawing speed of the food.
