Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an evaporator water receiving component and a refrigerator with an anti-condensation function. Background Art
[0002] Direct cooling freezers are widely used because they use natural convection cooling in which the cold air sinks in a closed box. They have the advantages of high air humidity, low moisture loss in food, and relatively low power consumption. In the prior art, the evaporator of a direct cooling freezer is generally installed at the top of the box. During the refrigeration process, a large amount of condensed water will condense on the surface of the evaporator, causing frost on the surface of the evaporator, which affects the refrigeration effect. Therefore, defrosting is required every once in a while, and condensed water will drip during defrosting. In order to prevent the above condensed water from affecting the food stored in the lower part of the box, a water receiving device will be installed under the evaporator. The traditional water receiving device, firstly, has a large enclosed area and a small cross-sectional area through which air can pass, and the air is not easy to convect naturally, resulting in slow refrigeration speed and uneven cold distribution, which affects the refrigeration effect; secondly, when the defrosted water drops to the water receiving device, the temperature at the bottom of the water receiving device will be lower than the air temperature in the freezer, resulting in condensation at the bottom of the water receiving device. As the operation time of the freezer increases, the condensed water will gradually gather and eventually drip on the food inside the cabinet, affecting the hygiene and safety of the food.

DETAILED DESCRIPTION
[0028] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.
[0029] Embodiment 1,
[0030] A refrigerator, combined Figure 1-5 As shown, it includes a cabinet body 1, a door body 2, an evaporator 3 and an evaporator water receiving assembly with an anti-condensation function arranged below the evaporator 3. The door body 2 is arranged on the rear side or the front side of the cabinet body 1, the evaporator 3 is arranged on the inner top of the cabinet body 1, and the evaporator water receiving assembly with an anti-condensation function is arranged below the evaporator 3 for collecting condensed water dripping from the evaporator 3.
[0031] The evaporator water receiving assembly with anti-condensation function includes a plurality of upper guide plates 41 located on the upper layer, a plurality of lower guide members 42 located on the lower layer and a liquid collecting box 5. The upper guide plates 41 and the lower guide members 42 are installed below the evaporator 3. The upper guide plates 41 and the lower guide members 42 are tilted in the left and right directions. The liquid collecting box 5 is installed at the lower end of the tilting direction. The bottom of the liquid collecting box 5 is lower than the lower guide member 42, so that all the condensed water in the lower guide member 42 can flow smoothly into the liquid collecting box 5.
[0032] In this embodiment, the upper guide plate 41 receives the condensed water dripping from the evaporator 3 and transports the condensed water to the lower guide member 42. The lower guide member 42 receives the condensed water dripping from the evaporator 3 and the condensed water transported by the upper guide plate 41, and then transports the received condensed water to the liquid collection box 5.
[0033] Multiple upper guides 41 and multiple lower guides 42 extend left and right, multiple upper guides 41 and multiple lower guides 42 are staggered up and down, and two adjacent upper guides 41 are spaced apart in the front-to-back direction, two adjacent lower guides 42 are spaced apart in the front-to-back direction, and adjacent upper guides 41 and lower guides 42 are spaced apart up and down to facilitate natural air convection. Both ends of the upper guide 41 in the width direction extend to directly above the two adjacent lower guides 42, that is, the front end of the upper guide 41 extends to directly above the adjacent lower guide 42 on the front side, and the rear end of the upper guide 41 extends to directly above the adjacent lower guide 42 on the rear side, ensuring that the condensed water on the evaporator 3 can flow down to the lower guide 42 after dripping onto the upper guide 41, and then flow into the liquid collecting box 5 through the lower guide 42. A downpipe 51 is provided at the bottom of the liquid collecting box 5 , and the installation position of the liquid collecting box 5 is inclined toward the end of the downpipe 51 at the bottom, so as to facilitate the drainage of condensed water in the liquid collecting box 5 .
[0034] The upper guide plate 41 has a downwardly inclined guide slope 411, and the condensed water drips onto the guide slope 411 and then flows to the lower guide member 42. Specifically, the upper surface of the upper guide plate 41 is one of an inverted V-shape, an upwardly convex arc, a regular polygonal structure, or an irregular polygonal structure, so that the dripping condensed water flows down quickly without gathering on its surface, and at the same time reduces the air resistance when the cold air sinks.
[0035] The lower guide member 42 has a guide groove 423 with an opening facing upward. The guide groove 423 is a V-shaped groove, a W-shaped groove, an arc-shaped groove, a regular or irregular polygonal groove, so that the dripping condensed water can flow smoothly into the liquid collecting box 5.
[0036] In this embodiment, the lower guide member 42 has an air insulation cavity 424 inside, which reduces the temperature difference between the upper and lower parts of the lower guide member 42 , thereby effectively avoiding condensation at the bottom of the lower guide member 42 .
[0037] Furthermore, a heating component 6 is provided in the air insulation cavity 424 of the lower air guide 42. The heating component 6 is an electric heating wire or a hot air pipe of a refrigeration system. The heating component 6 is in the air insulation cavity 424, so that the bottom surface temperature of the lower air guide 42 is increased, and condensation does not occur.
[0038] Specifically, the upper guide plate 41 and the lower guide member 42 are fixed with a connecting plate 44, and two connecting plates 44 are provided, one connecting plate 44 is provided at the left side of the upper guide plate 41 and the lower guide member 42, and the other connecting plate 44 is provided at the right side of the upper guide plate 41 and the lower guide member 42.

The connecting plate 44 is provided with mounting holes, and the connecting plate 44 is placed at both ends of the upper guide plate 41 and the lower guide member 42. The upper guide plate 41, the lower guide member 42 and the connecting plate 44 are assembled and fixed together by screws or welding. It should be understood by those skilled in the art that when the lateral length of the upper guide plate 41 and the lower guide member 42 assembly is large, in order to avoid sagging and deformation in the middle, a connecting plate 44 can be added in the middle to increase the strength.
[0039] The lower guide member 42 includes a lower guide plate 421 and a support member 422. The inner side walls of the support member 422 have a card slot 4221. The lower guide plate 421 is stuck in the card slot 4221, thereby forming the above-mentioned air insulation cavity 424 between the lower guide plate 421 and the support member 422. The support member 422 also has an installation groove 4222 for fixing the heating component 6.
[0040] Baffles 43 are also provided on the front and rear sides of the evaporator 3 to fix the evaporator water receiving assembly with anti-condensation function on the cabinet 1. One of the baffles 43 is located between the door body 2 and the evaporator 3. Ventilation holes are provided on the baffle 43. The upper end of the baffle 43 is higher than the upper end surface of the evaporator 3, and the lower end of the baffle 43 is lower than the evaporator 3. That is, the baffle 43 located on the side of the door body 2 is provided with vents and is an integrated type to prevent the human body from touching the evaporator 3 when the door body 2 is opened, and there is a safety hazard. The baffle 43 located on the other side is a split body. In addition to fixing the upper guide plate 41 and the lower guide member 42, it is opened to the maximum extent to facilitate the circulation of cold air and improve the refrigeration efficiency.
