Technical Field
[0001] The utility model relates to a tea storage cabinet with automatic heating and defrosting functions, belonging to the technical field of tea cabinets. Background Art
[0002] Existing tea cabinets have moisturizing and heat preservation functions. They are equipped with an evaporator for cooling. Over long periods of time, frost forms on the evaporator due to the evaporator's operating time. To address this issue, existing technologies typically use a PTC heater to defrost the evaporator. This heater is installed beneath the evaporator. During operation, the PTC heater heats the evaporator, generating hot air that rises and meets the evaporator, defrosting the frost. However, this method is slow to defrost and has drawbacks such as long heating times. Utility Model Content

[0025] The present invention will be described in detail below with reference to specific embodiments.
[0026] Example 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a tea storage cabinet with automatic heating and defrosting function includes a cabinet body 1, a compressor 2, an inner tank 3, an evaporator 4, and a heating and defrosting tube 5. The inner tank 3 is arranged in the cabinet body 1. The evaporator 4 is provided with a refrigerant inlet and a refrigerant outlet, and the compressor 2 is connected to the refrigerant inlet and the refrigerant outlet through a refrigerant tube. Like a conventional structure, an air duct 9 is provided in the inner tank, and the air duct 9 is connected to the inner tank, and the evaporator is arranged in the air duct. The heating and defrosting tube 5 is provided in the air duct, and the heating and defrosting tube 5 surrounds the evaporator 4. The air duct is provided with a drainage outlet, and the drainage outlet is provided with a drainage pipe 8. The inner tank in this example has two layers, each layer has an evaporator, and each evaporator is equipped with a matching heating and defrosting tube.
[0027] In this example, the heating and defrosting pipes include a front heating pipe 51 and a rear heating pipe 52. The front heating pipe is formed by bending one end of the heating pipe in a circuitous manner, and the rear heating pipe is formed by bending the other end of the heating pipe in a circuitous manner. There is a gap between the front heating pipe and the rear heating pipe. This simple structure is easy to manufacture.
[0028] In this example, the size of the gap matches the width of the evaporator, and the evaporator is located in the gap. Such a structure is conducive to improving the defrosting efficiency.
[0029] Working Principle: During use, when defrosting is required, the evaporator stops working and the defrost tube starts working. The heat from the defrost tube melts the frost on the evaporator, turning it into water and falling into the air duct. Because the defrost tube surrounds the evaporator, the tea cabinet defrosts quickly, efficiently, and with a simple structure.
[0030] Example 2: Figure 5 、 Figure 6 、 Figure 7 In this example, the front and rear sides of the evaporator are in contact with the front row heating tubes 51 and the rear row heating tubes 52, respectively. This structure is conducive to improving the efficiency of defrosting.
[0031] In this example, the evaporator is provided with a slot 6, and the heating and defrosting pipe is partially embedded in the slot 6, which allows for quick positioning and installation, and is easy to install. The heating and defrosting pipe is fixed to the evaporator.
[0032] Example 3: Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 In this example, one end of the aluminum tube 7 is inserted into the drain pipe, and the other end of the aluminum tube 7 is close to the heating and defrosting tube 5.
[0033] In this example, the other end of the aluminum tube is wrapped around the heating and defrosting pipe. The aluminum tube is heated together with the heating and defrosting pipe. Such a structure can prevent the drain pipe 8 from being blocked due to the presence of frost.
[0034] In this example, a portion of the heating and defrosting pipe is close to the bottom of the air duct 9. Such a structure is conducive to defrosting the frost at the bottom of the air duct.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
