Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of evaporators, and in particular relates to an evaporator with a hot air defrosting function. Background Art
[0002] Evaporation is the physical process of converting liquid into gas. Generally speaking, an evaporator is an object that converts liquid into gas. There are a large number of evaporators in the industry, among which the evaporator used in refrigeration systems is one of them. When the cold storage evaporator is used, due to the relatively high humidity in the cold storage room, the moisture in the air is very easy to frost on the surface of the evaporator and then cause ice;
[0003] Once the frost layer on the outer surface of the evaporator melts into water, it will drip into the water collecting pan located under the evaporator and drain away through the slope of the water collecting pan. If the accumulated water in the water collecting pan is not drained cleanly, the water in the water collecting pan may freeze again in a low temperature environment. After several defrosting cycles, the ice layer may cover the water collecting pan or even block the drain outlet, thus affecting subsequent use. Utility Model Content
[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide an evaporator with a hot air defrosting function.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0006] An evaporator with hot air defrosting function, comprising a shell with a heat exchange pipe installed inside, three fans installed on the shell, a liquid inlet pipe and a liquid outlet pipe connected to the shell, a water receiving box installed at the bottom of the shell, a water outlet pipe connected to the output end of the water receiving box, a heating pipe installed at the bottom of the water receiving box, and a knocking mechanism installed in the water receiving box;
[0007] The knocking mechanism includes a rotating shaft installed at the center position inside the water receiving box, a seesaw is rotatably installed on the rotating shaft, the rotating shaft is located at the center position of the seesaw, water storage tanks are symmetrically provided at both ends of the seesaw, the water storage tanks are opened with drainage outlets, and the two drainage outlets are symmetrically provided at both ends of the seesaw.
[0008] It is further defined that four sets of hanging ears are installed on both sides of the top of the shell. This design facilitates installation and ensures a firm installation.
[0009] It is further defined that the inner bottom of the water receiving box is an inclined cone inclined toward the water outlet pipe. Such a design ensures the self-flow effect of water.
[0010] It is further defined that the top edge of the water storage tank is coated with soft rubber, and such a design reduces the damage and noise caused by knocking.
[0011] It is further defined that the rotating shaft is installed with a bearing, and the seesaw is installed on the outer ring of the bearing. Such a design ensures the seesaw's seesaw's seesaw effect.
[0012] The beneficial effects of adopting the utility model are:
[0013] With the structural design of the utility model, when the ice on the shell is melted and falls into the water receiving box, part of it will fall into the water storage tank. Under the gravity of the water, the seesaw will tilt. Under the principle of balance, the two ends of the seesaw will move up and down reciprocatingly. During this movement, it will hit the inner bottom of the water receiving box, thereby achieving the purpose of preventing the bottom of the water receiving box from freezing.

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0023] like Figure 1 to Figure 4As shown, an evaporator with hot air defrosting function of the utility model comprises a shell 1 with a heat exchange pipe installed inside, three fans 2 are installed in the shell 1, a liquid inlet pipe 3 and a liquid outlet pipe 4 are connected to the shell 1, a water receiving box 5 is installed at the bottom of the shell 1, an output end of the water receiving box 5 is connected to a water outlet pipe 6, a heating pipe 7 is installed at the bottom of the water receiving box 5, and a knocking mechanism 8 is installed in the water receiving box 5;
[0024] The knocking mechanism 8 includes a rotating shaft 81 installed at the center position of the water receiving box 5, and a seesaw 82 is rotatably installed on the rotating shaft 81. The rotating shaft 81 is located at the center position of the seesaw 82. Water storage tanks 83 are symmetrically provided at both ends of the seesaw 82. The water storage tank 83 is provided with a drain outlet 84. The two drain outlets 84 are symmetrically provided at both ends of the seesaw 82.
[0025] In this embodiment, when an evaporator with a hot air defrosting function is used, the refrigeration liquid supply pipe sends cold air into the heat exchange pipe in the shell 1 through the liquid inlet pipe 3 to start heat exchange, and is discharged from the refrigeration return pipe through the liquid outlet pipe 4 for circulation. In this process, the shell 1 begins to freeze due to the cold, and the hot air discharged from the compressor is connected to the heating pipe 7, which transfers the hot air to the shell 1 for defrosting. After the defrosting is completed, the water droplets fall into the water receiving box 5 under their own weight. When the water volume on one side of the seesaw 82 is heavier than that on the other side, the seesaw 82 on the heavier side will drop down and hit the bottom of the water receiving box 5. Under this impact, the purpose of preventing the water in the bottom of the water receiving box from freezing is achieved. The water in the water storage tank 83 on the seesaw 82 on the dropped side is discharged from the drain port 84, and then becomes lighter. Under the weight of the water storage tank 83 on the other side, this side rises under the principle of balance, thereby achieving reciprocating knocking on the inner bottom of the docking water box 5.
[0026] The water drops in the water receiving box 5 are discharged from the water outlet 84, enter the defrost drain pipe and flow into the next process.
[0027] Preferably, four groups of hanging ears 9 are installed on both sides of the top of the shell 1. This design facilitates installation and ensures a firm installation. In fact, the number and position of the hanging ears 9 or the installation structure of the shell 1 can also be considered according to specific circumstances.
[0028] Preferably, the bottom of the water receiving box 5 is an inclined cone inclined toward the water outlet pipe 6. Such a design ensures the self-flow effect of water. In fact, the inclination angle of the bottom of the water receiving box 5 can also be considered according to specific circumstances.
[0029] Preferably, the top edge of the water storage tank 83 is coated with soft rubber. This design reduces the damage and noise caused by knocking. In fact, anti-collision measures can also be considered according to specific circumstances.
[0030] Preferably, the rotating shaft 81 is installed with a bearing, and the seesaw 82 is installed on the outer ring of the bearing. Such a design ensures the tilting effect of the seesaw 82. In fact, the structure that ensures the tilting effect of the seesaw 82 can also be considered according to specific circumstances.
[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
