[0034] Please refer to Figures 1-3 The present application provides a refrigeration equipment 100, which comprises a cabinet 110, a drawer and a drainage device 120.

[0035] Please refer to Figure 3 The cabinet 110 generally comprises an outer shell, a thermal insulation layer and an inner container. The outer shell can be made of metal (such as steel plate), and the surface is treated by paint spraying to prevent rust and has certain aesthetic appearance. The thermal insulation layer is located between the inner side of the outer shell and the inner container, which can be polyurethane foam, has good heat insulation performance, can effectively prevent heat exchange between the inside and the outside, and keep the internal temperature stable. The inner container is the part directly contacting the stored objects, which can generally be made of ABS plastic or stainless steel material, requires non-toxic and easy to clean, and the inside of the inner container forms a refrigeration chamber 111 for accommodating the stored objects.

[0036] It should be noted that the cabinet 110 can comprise one or more refrigeration chambers 111, and the refrigeration chamber 111 can be a refrigeration chamber and / or a freezing chamber. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device arranged inside or outside the cabinet 110. Figure 3The upper layer of the cabinet 110 shown in the figure comprises two refrigeration chambers 111, each of which is a refrigeration chamber. The lower layer comprises two refrigeration chambers 111, each of which is a freezing chamber. The cabinet 110 generally further comprises a door body, which also comprises an outer shell, a thermal insulation material and an inner liner, thereby ensuring good sealing and thermal insulation effects. The door body can be connected to the cabinet 110 through a hinge structure, allowing the door to open and close freely. The door body can be a single door or a double door, and the single door can also have a function of adjusting the opening direction left and right. A sealing strip can be installed at the edge of the door body, which is tightly attached to the cabinet 110 to prevent cold air leakage and seal the refrigeration chamber 111 together with the cabinet 110.

[0037] The cabinet 110 further comprises a refrigeration component 130, which is located inside the cabinet 110 and outside the refrigeration chamber 111. It should be noted that in an alternative embodiment, the cabinet 110 comprises an inner shell and an outer shell, and the inner shell and the outer shell have a mounting cavity therebetween. The inner shell forms the refrigeration chamber 111, and the refrigeration component 130 is located between the inner shell and the outer shell. The refrigeration component 130 can be arranged close to the first side wall 112 or the second side wall 113, and the present application does not limit this. Specifically, the refrigeration component 130 comprises an evaporator and a fan, and the evaporator extends along the height direction of the cabinet 110. In the present technical solution, the evaporator is arranged on one side of the refrigeration chamber 111 and extends along the height direction of the cabinet 110. Compared with the evaporator arranged at the end of the refrigeration chamber 111 in the prior art, the evaporator in the present technical solution can increase the volume of the refrigeration chamber 111 without increasing the volume of the cabinet 110 while ensuring the refrigeration effect. Further, the fan is used to send air to the refrigeration chamber 111.

[0038] One or more drawers are arranged in the refrigeration chamber 111 (for the convenience of observing the drain hole 122, the drawers are not shown in the figure). The drawers are slidably installed in the refrigeration chamber 111, and the drawers help users to store different types of storage objects separately, thereby improving the convenience of use. Independent temperature control can be provided for different drawers to meet the optimal storage temperature of different foods. In the technical solution provided by the present application, the refrigeration chamber 111 has a first side wall 112 and a second side wall 113 arranged opposite in the width direction. The two sides of the drawer are slidably connected to the first side wall 112 and the second side wall 113, respectively. The drawer can be removed and cleaned conveniently.

[0039] The drainage part 120 comprises a drainage hole 122. The drainage hole 122 is arranged at least on the first side wall 112 or the second side wall 113 adjacent to the refrigeration part 130, and at least part of the drainage hole 122 is arranged corresponding to the side wall of the drawer for leading out the condensed water. Since the refrigeration part 130 is arranged close to the first side wall 112 or the second side wall 113, there is more condensed water on the first side wall 112 and the second side wall 113 when the refrigeration air is blown, especially more condensed water on the side wall close to the refrigeration part 130. Therefore, the drainage hole 122 is arranged to correspond to leading out the condensed water, so as to prevent the drawer from being in contact with the condensed water and freezing. It should be noted that the drainage hole 122 should be arranged at least on the side wall adjacent to the refrigeration part 130. That is, the first side wall 112 adjacent to the refrigeration part 130, and the drainage hole 122 is arranged at least on the first side wall 112. Of course, the drainage hole 122 can also be arranged on both of them. The drainage hole 122 can be arranged only on the first side wall 112 or the second side wall 113 corresponding to the side wall of the drawer, or can also be arranged at other positions, and can be arranged corresponding to the side wall of each drawer, or can be arranged corresponding to a small number of drawers at the bottom, one side wall of the drawer can correspond to one or more drainage holes 122, and the utility model does not limit this. In the technical scheme provided by the utility model, the drainage hole 122 is arranged on the first side wall 112 or the second side wall 113, and the drainage hole 122 is arranged corresponding to the side wall of the drawer, so that the condensed water condensed on the first side wall 112 and the second side wall 113 can be effectively led out, the side wall of the drawer is prevented from being in contact with the condensed water and freezing, the drawer is ensured to be smoothly drawn, and the user experience is improved.

[0040] Since the condensed water generally flows in the form of water droplets, and the first side wall 112 and the second side wall 113 have a large area, a water guide structure needs to be provided for the condensed water to facilitate the condensed water to be guided into the drain hole 122. In an optional embodiment, a water guide groove can be formed on the first side wall 112 or the second side wall 113. The water guide groove can be in the shape of Y or a branch, and the condensed water is collected to the main path through the branch, and then guided to the drain hole through the main path to flow out. In another optional embodiment, the drain member 120 further comprises a water guide rib 121 arranged in abutment with the first side wall 112 and the second side wall 113, and the water guide rib 121 is used to guide the condensed water to the drain hole 122. Specifically, the water guide rib 121 is arranged in abutment with the first side wall 112 and the second side wall 113, and the condensed water droplets slide down along the first side wall 112 and the second side wall 113 under the action of gravity, flow and collect along the extension direction of the water guide rib 121 after sliding onto the water guide rib 121, and can be drained through the drain hole 122. One drain hole 122 can correspond to one or more water guide ribs 121. When one drain hole 122 corresponds to multiple water guide ribs 121, multiple water guide ribs 121 in a diverging shape can be arranged in the circumferential direction of the drain hole 122. One water guide rib 121 can also correspond to multiple drain holes 122, and multiple drain holes 122 can be arranged in the extension direction of the water guide rib 121, so that the condensed water is continuously guided out through the drain holes 122 on the path in the process of collecting and flowing.

[0041] As mentioned above, the two sides of the drawer are respectively connected with the first side wall 112 and the second side wall 113 in a sliding manner, so that the drawer is detachably connected with the cabinet 110. In order to facilitate the connection and sliding of the drawer, the first side wall 112 and the second side wall 113 are respectively provided with a slide rail 115 corresponding thereto, and the two sides of the drawer are respectively connected with the slide rails 115 in a sliding manner. Further, the drain hole 122 is arranged corresponding to the slide rail 115, and at least one end of the water guide rib 121 is connected with the slide rail 115. The two sides of the drawer are connected with the first side wall 112 and the second side wall 113 through the slide rails 115, so as to ensure the stability and smoothness of the drawer. By arranging the drain hole 122 corresponding to the slide rail 115, the side wall of the drawer can be conveniently positioned. In addition, since the slide rail 115 is arranged protruding from the first side wall 112 and the second side wall 113, the condensed water is also easy to condense and gather along the slide rail 115 during use. By connecting at least one end of the water guide rib 121 with the slide rail 115, the condensed water condensed on the first side wall 112 and the second side wall 113 and the condensed water condensed on the slide rail 115 can be conveniently guided into the drain hole 122. Generally, considering the factor of gravity, one end of the water guide rib 121 is connected with the bottom side of the slide rail 115. When the water guide rib 121 has only one end connected with the slide rail 115, the other end can be directly corresponding to the drain hole 122, such as directly partially inserted into the drain hole 122, or the tail portion is provided with an arc-shaped guide portion, so that the condensed water is easy to slide into the drain hole 122. When both ends of the water guide rib 121 are connected with the slide rail 115, the drain hole 122 should be located at the middle portion of the water guide rib 121, preferably at the lowest position of the water guide rib 121, so that the condensed water will converge from both ends to the lowest middle portion, and then be guided out of the drain hole 122.

[0042] In optional embodiments, the water guide rib 121 includes a water guide plate 1211, which can be linear or arc-shaped. In another optional embodiment, the water guide rib 121 includes a plurality of water guide plates 1211 connected in a bending manner. When the water guide rib 121 includes one water guide plate 1211, one end of the water guide rib 121 can be connected with the slide rail 115, and the other end can correspond to the drain hole. When the water guide rib 121 includes a plurality of water guide plates 1211 connected in a bending manner, both ends of the water guide rib 121 can be connected with both ends of the bottom side of the slide rail 115, and the drain hole 122 can be arranged at the middle position of the water guide rib 121. The water guide plates 1211 connected in a bending manner facilitate the efficient discharge of the condensed water falling from various directions and positions.

[0043] In order to facilitate the discharge of the condensed water, reference can be made to Figure 1 and Figure 2The water guide rib 121 comprises a plurality of water guide plates 1211, two adjacent water guide plates 1211 are connected by bending to form a chamfer 1212, and a drain hole 122 is arranged at the lowest chamfer 1212 of each water guide rib 121. In this way, the chamfer 1212 provides a certain accommodation space for the condensed water, and the condensed water is finally collected at the lowest chamfer 1212 and discharged through the corresponding drain hole 122. In an optional embodiment, in order to facilitate the discharge of the condensed water from the drain hole 122, the hole channel of the drain hole 122 is arranged to have a certain inclination angle, so as to facilitate the flow of the condensed water at the chamfer 1212; or a guide arc surface can be arranged at the chamfer 1212, and the outlet end of the guide arc surface is communicated with the drain hole 122, so as to facilitate the flow of the condensed water into the drain hole 122.

[0044] In an optional embodiment, the inclination angles of the water guide plates 1211 are arranged to be gradually increased; and / or, the inclination angles of the water guide plates 1211 are arranged to be gradually decreased. In this way, by means of the water guide plates 1211 with different angles, the condensed water can continuously flow due to the slope arrangement, and is not easy to stop condensation, so that the condensed water can be efficiently discharged.

[0045] Further, the included angle between each water guide plate 1211 and the horizontal direction is greater than or equal to 8°, and the greater the angle of the water guide plate 1211, the better the water guide effect, but attention should be paid to the fact that the inclination angle of the water guide plate 1211 should not be arranged to be too large to affect the normal use of the drawer and the rail.

[0046] For reference Figure 1 In an embodiment provided by the utility model, one drain hole 122 is arranged at one slide rail 115, and the two ends of the water guide rib 121 are connected with the two ends of the bottom side of the slide rail 115, and the drain hole 122 is arranged at the lowest chamfer 1212. Figure 2 Two drain holes 122 are arranged at one slide rail 115, one water guide rib 121 is correspondingly arranged between the two drain holes 122, the two ends of the water guide rib 121 are connected with the two ends of the bottom side of the slide rail 115, the two drain holes 122 are arranged side by side, correspond to the two lowest chamfers 1212 of the water guide rib 121 respectively, the condensed water on the left side is discharged from the left drain hole 122, and the condensed water on the right side is discharged from the right drain hole 122.

[0047] It should be noted that the number of drain holes arranged needs to be determined according to the thickness of the box body 110, the thickness of the box body 110 is 400mm-450mm, one side of each drawer corresponds to one drain hole 122, the thickness of the box body 110 is 450mm-600mm, one side of each drawer corresponds to at most two drain holes 122, and the thickness of the box body 110 is greater than 600mm, one side of each drawer corresponds to at least two or more drain holes 122, that is, at least two drain holes 122 are arranged. That is, the greater the thickness of the box body 110, the more drain holes 122 are needed.

[0048] Further, referring to Figure 3 The box 110 has a third side wall 114 between the first side wall 112 and the second side wall 113, and the third side wall 114 is provided with an air outlet 116. It should be noted that the refrigeration device 100 further comprises an evaporator and a fan, and the fan blows cold air from the air outlet 116 into the refrigeration chamber 111 for cooling. By arranging the air outlet 116 on the third side wall 114, the structure of the air outlet 116 can reduce the impact on the drawer, and the volume of the drawer can be significantly increased. Correspondingly, the drain hole 122 is arranged close to the third side wall 114, i.e. close to the rear half of the air duct formed by the fan in the refrigeration chamber 111. This is because the front half of the air duct is close to the door body and is more susceptible to temperature changes to produce condensate water, which can be guided to the rear half of the air duct by the water guide rib 121 for drainage. When one drain hole 122 is arranged, the drain hole 122 can be arranged at 3 / 4 of the thickness of the box 110, and when multiple drain holes 122 are arranged, the drain holes 122 can be evenly distributed.

[0049] In order to improve the drainage effect, the diameter of the drain hole is greater than 8mm, and a conduit and a water pan are further arranged in the box 110. One end of the conduit is connected to the drain hole 122, and the other end is connected to the water pan, which is used to collect and discharge the condensate water discharged from all the drain holes 122.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not limited to the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
