DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a temperature-controlled thawing device, including a rack 10 for placing various thawed products, the rack 10 having side wall panels, a rear wall panel and a bottom panel arranged opposite to each other on the left and right sides, forming a semi-enclosed rack 10 with an accommodating space. A placement rack 9 that can swing left and right is arranged in the accommodating space of the rack 10, and the placement rack 9 is used to place the items to be thawed. Ventilation pipes 4 are arranged on both sides of the placement rack 9, the ventilation pipes 4 are fixedly connected to the rear wall panel of the rack 10, and an electric heating component 5 is installed inside the ventilation pipe 4, and the electric heating component 5 faces the placement rack direction, and is used to heat and thaw the items to be thawed placed on the placement rack 9.

[0026] like Figure 1 As shown, the bottom of the placement rack 9 is connected to a shaking mechanism 8, and the shaking mechanism 8 drives the placement rack 9 to swing left and right relative to the bottom plate of the frame 10. Preferably, as Figure 3 and Figure 4 As shown, a guide rail 8-4 is installed on the upper surface of the bottom plate of the rack 10, and a slider 8-5 is provided at the bottom of the placement rack 9 to slide with the guide rail 8-4. The slider 8-5 slides on the guide rail 8-4 to drive the placement rack 9 to swing left and right. The shaking mechanism 8 includes a driving motor 8-2, and the output shaft of the motor 8-2 is connected to a rocker mechanism, one end of the rocker mechanism is connected to the placement rack 9, and the rocker mechanism is driven by the motor 8-2 to move, thereby driving the slider 8-5 at the bottom of the placement rack 9 to slide along the guide rail 8-4, so that the placement rack 9 swings left and right.

[0027] Specifically, the rocker mechanism includes a connecting rod 8-3 connected to the output shaft of the driving motor 8-2, the other end of the connecting rod 8-3 is connected to a fixed block 8-1, and the fixed block 8-1 is fixedly connected to the placement rack 9. When the driving motor 8-2 is started, it drives the connecting rod 8-3 to swing, and then pushes the fixed block 8-1 to drive the placement rack 9 to make left and right reciprocating motion on the guide rail 8-4.

[0028] In this embodiment, a temperature sensor (not shown) is provided in the accommodation space of the rack 10, the temperature sensor is electrically connected to the external controller, an exhaust fan 6 is installed on the side wall of the rack 10, and the external controller is electrically connected to the exhaust fan 6. When the temperature sensor detects that the temperature inside the accommodation space of the rack 10 is too high, it transmits a signal to the external controller, and the external controller starts the exhaust fan 6 to discharge the heat inside the accommodation space of the rack 10, which plays a role in rapid cooling and avoids the excessive temperature in the accommodation space from affecting the activity of the product.

[0029] In order to improve the uniformity of heating of the items to be thawed, the length of the ventilation pipe 4 corresponds to the height of the placement rack 9, and the electric heating component 5 is arranged along the length direction of the ventilation pipe 4. Preferably, the electric heating component 5 is an electric heating coil. The electric heating coil is connected to an external power supply component, and after power is turned on, the temperature of the electric heating coil rises, thereby increasing the air temperature inside the ventilation pipe 4.

[0030] Furthermore, a bendable tube 3 is provided on the ventilation duct 4, and one end of the bendable tube 3 is connected to a nozzle 2, and the nozzle 2 faces the object to be thawed. Preferably, the opening of the nozzle 2 is flat. The wind blown out of the flat opening has a faster wind speed than the normal opening, which improves the heat exchange efficiency of the product. A hot air blower 7 is connected to one end of the ventilation duct 4, and the hot air blower 7 is started to blow hot air into the ventilation duct 4, and then blows hot air from the nozzle 2 connected to the bendable tube 3 to the object to be thawed, so as to thaw the object to be thawed. Preferably, the bendable tube 3 is plastic and can be adjusted to any position, and is preferably a spring bendable tube.

[0031] In this embodiment, the placement rack 9 is divided into a plurality of placement spaces by a partition 9-2, and each partition 9-2 is a mesh structure. Dividing into a plurality of placement spaces can increase the number of thawed items placed, and the partition 9-2 adopts a mesh structure to facilitate the liquid generated during the thawing process to be discharged downward to prevent the thawed items from being soaked in water.

[0032] Furthermore, a water pan 9-1 is provided at the bottom of the rack 9 to receive the liquid generated by the thawed items and prevent the liquid from flowing out of the rack 9. The water pan 9-1 has a drain port (not shown in the figure), which is opened on time to drain the water in the water pan 9-1 for the next thawing.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
