Abstract
Description
Technical Field
[0001] The present application relates to a thawing device. Background Art
[0002] Since frozen food has high strength and rigidity and is very difficult to handle, it is usually thawed first. If it is left in the air to thaw naturally, it will take a long time, and ice or condensation will form on the surface of the food, causing the loss of food nutrients. Another common method is to soak the food in water to thaw, which can speed up the thawing process, but it will also affect the nutrition of the food and the taste when eaten.
[0003] Therefore, there is a need in the prior art for a thawing device that can thaw food quickly without affecting the nutrition and taste of the food. Utility Model Content

[0007] Wherein, the outer cover can be connected to the phase change heat conductive plate through a connecting piece, the phase change heat conductive plate is placed on a bracket or a base, and the water receiving trough is arranged at the lower part of the bracket or the base; or the outer cover can be arranged on the phase change heat conductive plate, and the phase change heat conductive plate is placed on a bracket or a base; at least one of the phase change heat conductive plate and the outer cover can have a shape matching the food to increase the contact area with the food; the outside of the food can be wrapped with a metal film bag; an elastic element can be installed in the outer cover, and the elastic element can be arranged between the outer cover and the phase change heat conductive plate, and the elastic element can apply pressure to the food placed on the phase change heat conductive plate; a control panel can be installed on the outer cover.

[0013] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0014] like Figure 1-2 As shown, the thawing device according to the present application includes a phase change heat conducting plate 1, an outer cover 2 and a water receiving tank 4. Among them, the outer cover 2 is arranged above the phase change heat conducting plate 1, and the water receiving tank 4 is arranged below the phase change heat conducting plate 1. The phase change heat conducting plate 1 preferably adopts a temperature equalizing plate, which can be made of metal materials such as copper plate or aluminum plate. The temperature equalizing plate is also called a heat equalizing plate, which utilizes the phase change evaporation of the cooling medium in the sealed space to quickly diffuse the heat to the cavity. After the medium is condensed into liquid at the condensation end, it flows back to the heat source end through capillary force and gravity. The heat transfer performance of the phase change heat conducting plate is tens to hundreds of times that of natural heat conducting materials. It has good thermal conductivity and has been widely used. Preferably, a pipe 11 can be provided in the phase change heat conducting plate 1, and a heat pipe medium is poured into the pipe 11 and sealed, so as to more quickly increase the thermal conduction efficiency of the phase change heat conducting plate.
[0015] like Figure 1-2 As shown, the outer cover 2 can be connected to the phase change heat conductive plate 1 by a connecting member such as a hinge to form a separate storage and thawing space, which can reduce the formation of frost or ice layer on the food by water vapor in the environment during thawing, affecting heat dissipation. At this time, the outer cover 2 and the phase change heat conductive plate 1 can be placed on a bracket or a base, and the water tank 4 is arranged inside the bracket or the base. In other embodiments, the outer cover 2 can also be directly covered on the phase change heat conductive plate 1, and the phase change heat conductive plate 1 can be placed on the bracket or the base.
[0016] Preferably, a control panel 3 can also be installed on the outer cover 2 to display the working status of the equipment and perform human-computer interactive control. The water tank 4 is used to receive condensed water that may be formed on the phase change heat conductive plate 1 and the outer cover 2 during the thawing process to prevent the condensed water from dripping or flowing directly in the thawing equipment placement area. The food 5 to be thawed is placed on the phase change heat conductive plate 1, and the contact surface between the two can be a plane or a wave shape to increase its contact surface with the food. In order to increase the contact area between the phase change heat conductive plate and the air contact surface, the contact surface between the phase change heat conductive plate and the air can be made into a wave shape or provided with fins. More preferably, the outer cover 2 can also be made of metal material stamping and forming, and a good contact effect is formed by reasonably matching the shape of the thawed food, and the cold of the thawed food can also be dissipated to the outside.
[0017] like Figure 1 As shown, the outside of the food 5 is also wrapped with a metal film bag. The metal film bag can be made of a metal film with a thickness of less than 0.1 mm, which makes it easy to achieve close contact between the metal film bag and the thawed food, thereby achieving a good heat transfer effect. Since the metal film is a good conductor of heat transfer, it can quickly transfer heat or cold, so that the entire thawed food is like being immersed in water, forming a three-dimensional contact conduction heat dissipation, thereby achieving rapid thawing. In addition, the liquid flowing out of the thawed food can be collected so that it will not flow freely in the thawing equipment, causing cleaning difficulties, and corrosion to the phase change heat conduction plate can also be avoided. The water condensed on the metal film bag is very clean. As long as the thawing is completed, it can be simply cleaned with a rag, thereby avoiding the condensation of water on the food and avoiding affecting the food.
[0018] like Figure 3 As shown, the thawing device according to the present application can also be provided with a fan 7, which is arranged below the phase-change heat-conducting plate 1, and forms an airflow with the ambient air where the thawing device is placed, generating surface forced heat exchange between the phase-change heat-conducting plate and the air contact surface. An electric heating wire 8 can also be installed at the bottom of the thawing device, and the electric heating wire 8 is arranged between the fan 7 and the phase-change heat-conducting plate 1 to form a temperature that does not deteriorate the thawed food, thereby achieving rapid thawing. Based on the above two technologies, the airflow formed by the fan passes through the electric heating wire to form hot air to generate surface forced heat exchange between the phase-change heat-conducting plate and the air contact surface, thereby achieving rapid thawing.
[0019] Preferably, a spring 9 can be installed on the outer cover 2, and the spring can apply pressure to the thawed food. When the food is thawed and softened, it can form a larger contact area with the phase change heat conduction plate to form a better heat transfer and heat conduction effect. The height of the spring can be adjusted to accommodate thawed food of different shapes and sizes, and the pressure spring structure can also be set in multiple groups to apply pressure to different parts of the thawed food.

Any technician in the technical field to which this application belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in this application, but the scope of patent protection of this application shall still be based on the scope defined in the attached claims.
