Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-3, the horizontal air-cooled refrigerator of this embodiment includes a horizontal cabinet body 1 and a door body 2, and the left end of the horizontal cabinet body 1 is provided with an evaporation cavity 11 and an air outlet duct 12. The right end and the bottom of the horizontal cabinet body 1 are provided with a return air duct 13, the outlet air duct 12 is located on the inner wall of the left end and has a plurality of air outlets, and the return air duct 13 is located at The inner wall of the right end is provided with a plurality of air inlets, and the air outlet is arranged opposite to the air inlet; An air exhaust port is provided, and an air return port is provided at the lower part of the evaporation cavity 11 , the air outlet duct 12 is connected to the air exhaust port, and the return air duct 13 is connected to the air return port.

Specifically, the horizontal air-cooled freezer in this embodiment is provided with an air outlet and an air inlet on opposite ends of the horizontal cabinet body 1 respectively, and after heat exchange treatment by the evaporator 3, cold air is output from the air outlet to the horizontal cabinet. The items in the cabinet 1 are refrigerated, and the opposite air inlet is used for suction, so that the cold air can flow through the gaps between the items in the horizontal cabinet 1, so that the cold air is evenly distributed in the horizontal cabinet 1 Inside, the temperature distribution uniformity in the horizontal cabinet body 1 is improved. Wherein, in order to improve the uniformity of temperature distribution, the inner wall of the left end is provided with a plurality of air outlets with gradually smaller sizes from top to bottom, and the inner wall of the right end is provided with multiple sizes from top to bottom. The air inlet gradually becomes larger. Specifically, the size of the air outlet gradually decreases from top to bottom, which can ensure sufficient cold air distribution in the upper part of the cold horizontal cabinet 1, so that the upper cold air can cover the entire cross-sectional area of the horizontal cabinet 1, The size of the air inlet gradually increases from top to bottom, so that the air suction capacity of the lower part of the horizontal cabinet body 1 is improved, thereby effectively enhancing the ability of cold air to penetrate into the gaps between objects, and it is more conducive to improving the uniform distribution of cooling capacity. sex.

By setting a plurality of air outlets and air inlets at both ends of the horizontal cabinet, and the air outlets are arranged opposite to the air inlets, during the cooling process, the cold air output by the air outlets can be sucked by the oppositely arranged air inlets. It can ensure that the cold air can circulate in the horizontal cabinet, so that the cold distribution of the refrigerator can be evenly distributed to improve the cooling effect.

Based on the above technical solution, optionally, as shown in Figures 2-4, the fan 4 is arranged in the air outlet, and the horizontal cabinet 1 is also provided with a switchable windshield assembly 5, the windshield assembly 5 Used to cover the blower fan 4 . Specifically, a switchable windshield assembly 5 is arranged at the exhaust outlet 111 of the evaporation chamber 11. In actual use, under normal cooling conditions, the windshield assembly 5 is in an open state, so that the airflow generated by the fan 4 It is not blocked by the wind cover assembly 5, so that the cold air formed by the fan 4 through the heat exchange of the evaporator 3 is input into the refrigeration space of the horizontal cabinet 1 through the air outlet duct 12 to cool the articles; and when it is necessary to perform defrosting treatment At this time, the wind cover assembly 5 is closed. At this time, the wind cover assembly 5 blocks the air outlet of the fan 4, thereby preventing the hot air generated by the evaporator 3 heating and defrosting in the evaporation chamber 11 from leaking through the fan 4, thereby avoiding the leakage of the horizontal cabinet. The temperature fluctuation of the refrigerated space of body 1 is too large, which can effectively reduce the loss of cooling capacity and reduce energy consumption.

Further, in order to control the switch of the windshield assembly 5 conveniently, the windshield assembly 5 includes a windshield 51 and a drive mechanism 52 for driving the windshield 51 to move, and the windshield 51 is along the wind outlet direction of the fan 4 Slidably arranged on the blower fan 4 . Specifically, in actual use, the wind cover 51 can be driven by the driving mechanism 52 to move relative to the fan 4. Under the cooling condition, the driving mechanism 52 drives the wind cover 51 to move along the air outlet direction of the fan 4, so as to Make the wind cover 51 far away from the fan 4, so that the fan 4 can blow out the wind smoothly; and in the defrosting mode, the drive mechanism 52 drives the wind cover 51 to move in the opposite direction along the wind outlet direction of the fan 4, so that the wind cover 51 covers The blower 4 is blocked, thereby indirectly covering the exhaust outlet 111 of the evaporation chamber 11, so as to prevent defrosting hot air from entering the cabinet. Preferably, the windshield assembly 5 further includes a windshield ring 53 , and the windshield ring 53 is arranged on the periphery of the fan 4 and arranged around the air outlet 111 of the evaporation cavity 11 . Specifically, through the cooperation of the windshield 51 and the windshield ring 53 around the fan 4, the fan 4 can be better effectively sealed by the windshield assembly 5, wherein, when the windshield is in the closed state, the windshield The edge of the windshield 51 can abut against the edge of the windshield ring 53, or the edge of the windshield 51 is inserted into the windshield ring 53, or the windshield ring 53 is inserted into the In the windshield 51 . In addition, in order to ensure smooth sliding of the windshield 51 , the windshield assembly 5 further includes a guide rod 54 for guiding the sliding of the windshield 53 , and the guide rod 54 is fixed in the horizontal cabinet body 1 .

By setting the fan at the exhaust outlet of the evaporating chamber, and configuring the fan with a switchable fan cover assembly, in the normal cooling process, the fan cover assembly is opened, and the airflow generated by the fan startup can replace the evaporator in the evaporation chamber. The cold air generated by the heat is sent to the end air outlet and side air outlet through the air outlet of the evaporation chamber to cool the items in the cabinet. During the defrosting process, the wind cover assembly is closed to cover the fan In this way, the hot air generated by defrosting in the evaporation chamber will not enter the cooling area in the cabinet through the air outlet of the evaporation chamber, and the use of the wind cover assembly can more conveniently cut off the hot air generated by defrosting and leak into the cabinet In the interior, the temperature fluctuation of the horizontal air-cooled freezer is small during the defrosting process to improve the cooling effect and reduce the operating energy consumption.
