By arranging a refrigeration pipeline and a refrigerator that can refrigerate in the display cabinet body, it achieves good refrigeration effect and good preservation effect for dishes. However, for dishes that are initially in a frozen state and need to be thawed and restored to freshness, it lacks the function of thawing and restoring freshness. Existing common preservation cabinets only have the function of keeping the display box warm and cannot participate in the whole thawing and preservation process.

[0004] Therefore, this application provides a crispy food insulation and crispness preservation display cabinet to solve the above problems. Utility Model Content

[0005] This application provides a crispy food insulation and crispness preservation display cabinet, aiming to solve the problems in the background technique that the existing dish display cabinets lack the function of thawing and restoring freshness for dishes that are initially in a frozen state and need to be thawed and restored to freshness, and existing common preservation cabinets only have the function of keeping the display box warm and cannot participate in the whole thawing and preservation process.

[0006] To achieve the above object, this application provides the following technical solution: A crispy food insulation and crispness preservation display cabinet, including a display mechanism and a temperature control mechanism fixedly installed in the display mechanism:

[0007] The display mechanism includes a base and a cabinet body fixedly installed on the base. Two display platforms are fixedly installed in the cabinet body from top to bottom. A cabinet door is hinged on the outer side wall of the cabinet body, and a transparent cover is fixedly installed on the side of the cabinet body opposite to the cabinet door;

[0008] The temperature control mechanism includes a heating plate fixedly installed in the base and a controller electrically connected to the heating plate. The controller is electrically connected to a temperature sensor and a humidity sensor disposed in the cabinet through circuits, and the controller is also electrically connected to a control panel fixedly connected to the outer side wall of the base through a circuit. In this way, when thawing and refreshing frozen dishes, open the cabinet door, place the frozen dishes on the two display surfaces one by one, and then start the heating plate through the control panel. The temperature sensor and the humidity sensor will feedback the temperature and humidity information in the cabinet to the controller in real time. During the thawing stage, adjust the heating temperature of the heating plate to 140°C and maintain it for 90 minutes. This process thaws and restores the crispness of the crispy food from the frozen fresh-keeping state. Then, adjust the temperature to 45°C for long-term heat preservation to make the crispy food in the best edible state. The transparent cover is used to directly display the dishes to customers, so that the device not only plays a role in keeping the crispy food warm, but also automatically participates in the whole process of the crispy food from the frozen fresh-keeping state to the best edible state. Compared with the common display cabinet that only has the function of keeping the display box warm, the use effect is better.

[0009] Preferably, in order to discharge the water vapor generated during heating, a plurality of evenly arranged exhaust holes are circumferentially distributed on the outer side wall of the cabinet door. During the thawing process, a large amount of water vapor will be generated due to the heating of the heating plate, which is discharged through the exhaust holes to ensure that there is no excessive water accumulation in the cabinet and avoid affecting the crispy food.

[0011] Preferably, in order to dissipate heat from the heating plate, a plurality of heat dissipation holes are evenly opened on the outer side wall of the base. When the heating plate is working, the heating plate and the controller will generate a large amount of heat. In order to reduce the loss of the equipment, heat dissipation is carried out through the heat dissipation holes to extend the service life of the equipment.

[0012] Preferably, in order to collect the condensed water, the display cabinet further includes a condensed water circulation mechanism. The condensed water circulation mechanism includes a condensed water plate fixedly installed on the side of the cabinet body away from the heating plate and a condenser fixedly installed on the outer wall of the cabinet body and attached to the condensed water plate. A water receiving hopper adapted to the condensed water plate is fixedly installed in the cabinet body. When the heating plate works to thaw the frozen dishes, start the condenser at the same time, so that the condensed water plate serves as the main condensation surface, and most of the generated water vapor is concentrated and collected on the condensed water plate. Then, during the heat preservation process, the temperature drops, and the condensed water drips into the water receiving hopper to avoid the condensed water dripping on the dishes and affecting the quality of the dishes, further ensuring the taste quality of the dishes.

[0013] Preferably, in order to ensure the environmental humidity inside the cabinet, a water delivery pipe is fixedly installed at the bottom of the water receiving hopper. One end of the water delivery pipe away from the water receiving hopper penetrates through the side wall of the cabinet and a water pump circuit-connected to the controller is fixedly installed at the end. A water return pipe extending into the cabinet is fixedly installed on the water pump. One end of the water return pipe located inside the cabinet is fixedly installed with an atomizing nozzle. The environmental humidity inside the cabinet is detected by a humidity sensor. When the environmental humidity is lower than the environmental humidity required for dish freshness preservation, the controller controls the water pump to start, pumps out the condensed water collected in the water receiving hopper through the water delivery pipe, then enters the cabinet through the water return pipe, and is sprayed out by the atomizing nozzle to supplement the environmental humidity inside the cabinet, achieving the effect of recycling and saving resources.

[0014] For this display cabinet, during the thawing stage, the heating temperature of the heating plate is adjusted to 140 °C and maintained for 90 minutes. During this process, the crispy food thaws and becomes crispy again from the frozen fresh state. Subsequently, the temperature is adjusted to 45 °C for long-term heat preservation, making the crispy food in the best edible state. The transparent cover is used to directly display the dishes to customers, so that the device not only plays a role in heat preservation of the crispy food, but also automatically participates in the whole process of the crispy food from the frozen fresh state to the best edible state. Compared with the common display cabinet that only has the heat preservation function of the display box, the use effect is better.

[0015] For this display cabinet, the environmental humidity inside the cabinet is detected by a humidity sensor. When the environmental humidity is lower than the environmental humidity required for dish freshness preservation, the controller controls the water pump to start, pumps out the condensed water collected in the water receiving hopper through the water delivery pipe, then enters the cabinet through the water return pipe, and is sprayed out by the atomizing nozzle to supplement the environmental humidity inside the cabinet, achieving the effect of recycling and saving resources.

[0024] This embodiment provides a brittle object heat preservation and crispness preservation display cabinet, as Figures 1-4 shown. The display cabinet includes a display mechanism 1 and a temperature control mechanism 2 fixedly installed in the display mechanism 1:

[0025] The display mechanism 1 includes a base 11 and a cabinet 12 fixedly installed on the base 11. Two display tabletops 13 are fixedly installed in the cabinet 12 from top to bottom. A cabinet door 14 is hinged on the outer side wall of the cabinet 12. A transparent cover 15 is fixedly installed on the side of the cabinet 12 opposite to the cabinet door 14;

[0026] The temperature control mechanism 2 includes a heating plate 21 fixedly installed in the base 11 and a controller 22 electrically connected to the heating plate 21. A temperature sensor 23 and a humidity sensor 24 arranged in the cabinet 12 are electrically connected to the controller 22. A control panel 25 fixedly connected to the outer side wall of the base 11 is also electrically connected to the controller 22.

[0027] During use, open the cabinet door 14, place the frozen dishes one by one on the two display surfaces 13, and then start the heating plate 21 through the control panel 25. The temperature sensor 23 and the humidity sensor 24 will timely feedback the temperature and humidity information inside the cabinet body 12 to the controller 22. During the thawing stage, adjust the heating temperature of the heating plate 21 to 140 °C and maintain it for 90 minutes. This process thaws and restores the crispness of the crispy items from the frozen fresh-keeping state. Subsequently, adjust the temperature to 45 °C for long-term heat preservation to keep the crispy items in the best edible state. The transparent cover 15 is used to directly display the dishes to customers, so that the device not only plays a role in heat preservation of the crispy food, but also automatically participates in the whole process of the crispy items from the frozen fresh-keeping state to the best edible state. Compared with the common display cabinet that only has the heat preservation function of the display box, the use effect is better.

[0028] Specifically, a number of uniformly arranged exhaust holes 16 are circumferentially distributed on the outer side wall of the cabinet door 14. During use, a large amount of water vapor will be generated due to the heating of the heating plate 21 during the thawing process and discharged through the exhaust holes 16 to ensure that excessive water does not accumulate inside the cabinet body 12 and avoid affecting the crispy items.

[0029] More specifically, a door handle 17 is fixedly installed on the outer side wall of the cabinet door 14. During use, pull the cabinet door 14 through the door handle 17 to quickly open and close the cabinet door 14, which is convenient and fast.

[0030] Furthermore, a number of heat dissipation holes 18 are uniformly formed on the outer side wall of the base 11. During use, when the heating plate 21 is working, both the heating plate 21 and the controller 22 will generate a large amount of heat. To reduce the loss of the equipment, heat dissipation is carried out through the heat dissipation holes 18 to extend the service life of the equipment.

[0031] Embodiment 2

[0032] Different from Embodiment 1, a large amount of water vapor will be generated when the heating plate 21 thaws.

The condensed water circulation mechanism 3 includes a condensed water plate 31 fixedly installed on one side of the cabinet body 12 away from the heating plate 21 and a condenser 32 fixedly installed on the outer wall of the cabinet body 12 and attached to the condensed water plate 31. A water receiving hopper 33 adapted to the condensed water plate 31 is fixedly installed inside the cabinet body 12. During use, when the heating plate 21 works to thaw the frozen dishes, start the condenser 32 at the same time, so that the condensed water plate 31 serves as the main condensation surface, and most of the generated water vapor is concentrated and collected on the condensed water plate 31. Subsequently, during the heat preservation process, the temperature drops, and the condensed water drips into the water receiving hopper 33 to avoid the condensed water dripping on the dishes and affecting the quality of the dishes, and further ensure the taste quality of the dishes.

[0033] Further, a water delivery pipe 34 is fixedly installed at the bottom of the water receiving hopper 33. One end of the water delivery pipe 34 away from the water receiving hopper 33 penetrates through the side wall of the cabinet body 12 and a water pump 35 circuit-connected to the controller 22 is fixedly installed at the end. A water return pipe 36 extending into the cabinet body 12 is fixedly installed on the water pump 35. An atomizing nozzle 37 is fixedly installed at one end of the water return pipe 36 located inside the cabinet body 12.

[0034] During use, the environmental humidity inside the cabinet body 12 is detected by the humidity sensor 24. When the environmental humidity is lower than the environmental humidity required for dish fresh-keeping, the controller 22 controls the water pump 35 to start, pumps out the condensed water collected in the water receiving hopper 33 through the water delivery pipe 34, then enters the cabinet body 12 through the water return pipe 36, and is sprayed out by the atomizing nozzle 37 to supplement the environmental humidity inside the cabinet body 12, achieving the effects of recycling and resource saving.

[0035] The above are only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
