A tank assembly 100 for a refrigeration apparatus 200 in accordance with an embodiment of the present invention will now be described with reference to Figures 1-4. As shown in FIGS. 1 to 4, a tank assembly 100 for a refrigerating apparatus 200 according to an embodiment of the present invention includes a tank, a duct cover 1, and an air circulation device (such as a centrifugal fan 2). The tank (not shown) of the refrigerating apparatus 200 may have a compartment, such as a compartment, etc., and the duct cover 1 is disposed in the tank of the refrigerating apparatus and forms a wind with the inner wall surface of the tank. Road.

The air-cooled refrigeration equipment mainly uses air for cooling. When the high-temperature air flows through the evaporator built in the freezing chamber, heat exchange occurs directly with the evaporator, and the temperature of the air is lowered. At the same time, the cold air sent from the evaporator heat exchange chamber circulates in the air duct formed between the duct cover 1 and the tank, thereby realizing the refrigeration function of the refrigeration equipment.

Optionally, the air duct can be divided into an air inlet duct and a return air duct, and the air inlet duct and the return air duct are spaced apart from each other, and the air duct cover 1 can be respectively exchanged with the air in the air inlet duct and the air in the air compartment. heat. It can be understood that the cold air sent from the heat exchange chamber of the freezer evaporator can be circulated in the air inlet duct and the return air passage first, and the air duct cover 1 is cooled by the cold air, and then the air duct cover 1 is cooled by the air duct cover 1 Therefore, the cold air can be prevented from blowing directly into the compartment, and the moisture in the compartment is taken away by the air, thereby causing low humidity in the compartment, which is not conducive to the preservation of the indoor fruits and vegetables.

As shown in FIG. 1 and FIG. 3, the tank assembly 100 for the refrigeration apparatus 200 of the embodiment of the present invention is provided with an air circulation device (such as a centrifugal fan 2), which is disposed in the compartment and can be fastened by screws. The piece is fixed to the duct cover 1, and the air circulation device is used to blow the air in the compartment to the air duct cover 1 by circulation. It can be understood that, since the temperature of the air duct cover 1 is lower than the temperature of the compartment, when the humidity of the compartment is high, it is easy to generate condensation on the surface of the air duct cover 1, so that it passes through the compartment (such as the compartment). The air circulation device is disposed in the air to blow the air in the compartment to the air duct cover 1 by circulation, so that a small amount of condensation on the air duct cover 1 can be air-dried, thereby keeping the humidity in the room moderate.

According to the embodiment of the present invention, the tank assembly 100 for the refrigerating apparatus 200 can prevent the air in the compartment by circulating the air in the compartment to the duct cover 1 by providing an air circulation device in the compartment. Condensation on the duct cover 1 improves the user experience.

As shown in FIG. 1 to FIG. 3, the air circulation device may be fixed on the front surface of the air duct cover 1. Alternatively, the air circulation device may be a centrifugal fan 2, and the centrifugal fan 2 may be a casing, a main shaft 22, an impeller 21, and a bearing. The transmission mechanism and the motor are composed of the air returning port of the centrifugal fan 2 facing the inner chamber and the air outlet facing the air duct cover 1, so that the air in the compartment enters the inside of the fan from the axial direction, and the direction of the airflow when flowing through the impeller 21. The radial direction is changed, and the air outlet of the centrifugal fan 2 flows out, and is blown to the surface of the air duct cover 1, so that condensation of the surface of the air duct cover 1 can be prevented.

Further, as shown in FIG. 1 to FIG. 3, the tank assembly may further include: a fan cover 3, the fan cover 3 may be sleeved on the centrifugal fan 2, and the fan cover 3 may have a fan cover opening 31, and the fan cover opening 31 Corresponding to the return air inlet of the centrifugal fan 2, the air return opening of the centrifugal fan 2 is exposed from the fan cover opening 31, thereby ensuring that the air in the compartment can smoothly enter the centrifugal fan 2.

Further, the fan cover 3 is spaced apart from the front surface of the air duct cover 1 , and a flow guiding channel 32 is defined between the fan cover 3 and the front surface of the air duct cover 1 , and the flow guiding channel 32 surrounds the centrifugal fan 2 The air outlet of the centrifugal fan 2 communicates with the flow guiding channel 32. In this way, the airflow flowing out of the centrifugal fan 2 flows out along the flow guiding channel 32, thereby better circulating the airflow in the compartment, and making the temperature and humidity in the compartment more uniform.

Alternatively, the fan cover 3 can be configured in a dish shape, that is, the front surface of the fan cover 3 is convex and the back surface is concave, so that a concave portion is formed on the back surface of the fan cover 3, and the centrifugal fan 2 is partially housed in the concave portion, which is advantageous for saving. The arrangement space of the air circulation device makes the layout of the air duct cover 1 reasonable and compact. At the same time, the fan cover 3 can play the role of hiding the centrifugal fan 2, making the compartment more beautiful.

Alternatively, the fan cover 3 may be fixed to the front surface of the air duct cover 1 by a connecting strip 33. Further, the connecting strip 33 may be plural, for example four, and the four connecting strips 33 may be circumferentially spaced apart, thereby Under the condition that the connection of the fan cover 3 on the air duct cover 1 is ensured, the air outlet of the centrifugal fan 2 can also flow out of the escape space.

As shown in FIG. 1 to FIG. 2, the air duct cover 1 may include a rear plate portion 11 and a top plate portion 12, and the rear half portion may be a rectangular plate, and the centrifugal fan 2 may be disposed at a central portion of the rear plate portion 11, that is, centrifugally. The distance between the fan 2 and the four corners of the rear plate portion 11 is equal, so that the temperature and humidity in the compartment can be kept uniform.

Of course, in other embodiments, the centrifugal fan 2 may also be four, and four centrifugal fans 2 are respectively disposed at four corners of the rectangular rear plate portion 11, whereby the plurality of centrifugal fans 2 are simultaneously opposed to each other. The air is circulated, so that the air in the compartment can be more quickly exchanged with the front surface of the duct cover 1, thereby speeding up the cooling rate of the compartment, and at the same time helping to eliminate the condensation on the front surface of the duct cover 1, and The indoor temperature and humidity fluctuate less.

According to still another embodiment of the present invention, the air circulation device may be a cross flow fan, the cross flow fan may be composed of an impeller, a duct and a motor, and the cross flow fan may be disposed at the top and/or the bottom of the rear plate portion 11, in other words, The cross flow fan may be disposed at the top of the rear plate portion 11 of the duct cover 1, or the cross flow fan may be disposed at the bottom of the rear plate portion 11 of the duct cover 1, or the cross flow fan may be two or two The cross flow fans are respectively disposed at the top and bottom of the rear plate portion 11, but are not limited thereto.

Thereby, the air duct cover 1 has high strength and long service life. At the same time, the closed cover plate without the air outlet is used to make the air duct cover 1 independently exchange heat with the air in the air duct and the air in the inner chamber of the tank 1. A closed air duct chamber is formed between the air duct cover 1 and the tank, and an air inlet duct and a return air duct are formed in the air duct chamber, and cold air sent from the freezing chamber is circulated inside the air duct chamber. With the wind channel The cover plate performs heat exchange, and the air duct cover 1 exchanges heat with the compartment in the tank. Since the air duct cover 1 is made of metal, the heat exchange effect is good, and the cooling amount can be quickly radiated into the compartment. The refrigeration function of the compartment and the preservation of the fruits and vegetables placed in the compartment are completed. Moreover, since the air duct cover 1 adopts a closed structure without a ventilation hole, the cold air does not undergo a large circulation, that is, does not enter the compartment, so that the water vapor in the compartment is not taken away, thereby ensuring the indoor compartment. humidity.

Further, the back surface of the air duct cover 1 is in contact with the support frame 15, and the air circulation device is fixed to the support frame 15 by a threaded fastener, and the threaded fastener can pass through the panel 13, that is, the screw fastening The air circulation device can be fixed to the support frame 15 after passing through the air circulation device and the panel 13 in order from the front to the rear, whereby the air circulation device is stably installed in the compartment and is firmly connected.

As shown in FIG. 4, the support frame 15 may be provided with a main longitudinal air duct 151 and a horizontal air duct 152. The horizontal air duct 152 may be a plurality of, and the plurality of horizontal air ducts 152 are connected to the main longitudinal air duct 151, and the horizontal air duct is connected. 152 may be located on one or both sides of the main longitudinal air duct 151. Further, spacer ribs 153 may be disposed between the adjacent two lateral air ducts 152. Therefore, the cold air sent by the evaporator heat exchange chamber enters the main longitudinal air duct 151 and may enter the plurality of horizontal air ducts 152 respectively. Then, the horizontal air passage 152 flows back to the air passage, so that sufficient heat exchange of the air duct cover 1 can be achieved, and the cooling effect is better. At the same time, the spacer 153 can also function to increase the strength of the duct cover 1.

Optionally, as shown in FIG. 1 and FIG. 2, the first side wall 131 and the second side wall 132 of the air duct cover 1 may be formed with a fixing portion 14 for mounting the air duct cover 1 to the tank. Specifically, the fixing portion 14 may be plural, and the plurality of fixing portions 14 may be spaced apart along the length direction of the air duct cover 1, thereby ensuring the connection of the air duct cover 1 and the tank.

Optionally, at least one side wall of the air duct cover 1 may be formed with a flange, and a claw may be formed on the flange, and correspondingly, a sidewall of the support frame 15 corresponding to the air duct cover 1 may be formed. There is a card slot 154, and the claws cooperate with the card slot 154, whereby the support frame 15 can be fixedly connected to the air duct cover 1 and the connection mode is simple.
