Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a water tray assembly for refrigeration equipment and refrigeration equipment. Background Technology

[0002] Currently, most refrigerators on the market primarily achieve their cooling function through an evaporator and refrigerant in the piping. During use, because the evaporator's temperature is relatively low compared to the outside temperature, water vapor from the outside air may condense and form frost on its surface, resulting in a large amount of ice buildup. This can negatively impact the refrigerator's cooling performance and efficiency, and may even lead to quality issues. To address this evaporator frost problem, existing technologies incorporate heating wires on the evaporator. During defrosting, these wires heat the evaporator to remove the frost. Additionally, a drip tray is positioned directly below the evaporator to collect the melted frost. The drip tray has drainage channels to allow the melted frost to drain away.

[0003] The drip tray is usually located below the evaporator, and its cross-section is approximately inverted cone-shaped. The inlet of the drain channel is usually located at the lowest point of the drip tray. The heating wire is wrapped around the evaporator to provide heat to the outer surface of the evaporator. After receiving heat, the frost on the outside of the evaporator melts. The drip tray is used to collect the water dripping from the melting frost on the outer surface of the evaporator. The water falling into the drip tray slides down the surface of the drip tray to the inlet of the drain channel and is discharged outside the refrigerator through the drain channel.

[0004] In actual use, the existence of drainage channels causes the cooling chamber to be connected to the outside, which can easily cause hot air from the outside to enter the cooling chamber and thus affect the cooling effect. Therefore, how to effectively prevent heat from entering the cooling chamber through the drainage channels is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a water tray assembly for refrigeration equipment to overcome the shortcomings of the prior art. It can effectively prevent external heat from entering the cooling chamber through the drainage channel, reduce the heat loss of the evaporator, and improve the refrigeration efficiency.

[0006] The water tray assembly for refrigeration equipment provided by the present invention includes:

[0007] A water receiving tray includes a tray body with a water collection trough and a drainage channel communicating with the water collection trough, wherein the drainage channel has a water inlet provided on the tray body;

[0008] A cap assembly has a cap rotatably mounted on the water receiving tray, and the size of the cap is not larger than the size of the water inlet. The cap has a capped state and a non-capped state.

[0009] When the cap is in the sealed state, the cap is located above the water inlet and the plane of the cap is 1-3mm higher than the plane of the water inlet in the vertical direction;

[0010] When not covered, the cover is positioned above the water inlet.

[0011] Furthermore, the capping assembly also has a support frame disposed on the disc body and a rotating arm disposed on the cap, the rotating arm being rotatably mounted on the support frame via a rotating shaft.

[0012] Furthermore, there are two rotating arms, which are symmetrically arranged on opposite sides of the cover. The rotating shaft is located between the two rotating arms and is rotatably connected to the support frame.

[0013] Furthermore, the projection of the rotation axis onto the plane where the cap is located is located on the central axis of symmetry of the cap, so that the cap moves to the capped state under its own gravity.

[0014] Furthermore, the water receiving tray has a length direction and a width direction, with the water inlet located off-center from the center of the water receiving tray in the length direction, and the rotating shaft extending along the width direction.

[0015] Furthermore, the support frame includes a first support plate and a second support plate disposed on opposite sides of the inlet, and the rotating arm includes a first support arm and a second support arm disposed on opposite sides of the cover and perpendicular to the cover.

[0016] The first support arm is rotatably mounted on the first support plate via a rotating shaft, and the second support arm is rotatably mounted on the second support plate via the same rotating shaft.

[0017] Furthermore, the first support arm includes a first mounting plate, a second mounting plate, and a connecting plate connecting the first mounting plate and the second mounting plate, which are disposed opposite to each other on opposite sides of the first support plate. The first mounting plate and the second mounting plate are both disposed parallel to the first support plate and form a downward-facing receiving groove with the connecting plate. The first support plate is adapted to the receiving groove and positioned within the receiving groove.

[0018] Furthermore, the rotating shaft has a shaft body and limiting rings disposed on opposite sides of the shaft body, wherein the cross-sectional dimension of the limiting rings is larger than the cross-sectional dimension of the shaft body;

[0019] The first mounting plate is provided with a first through hole adapted to the limiting ring, and the second mounting plate is provided with a second through hole adapted to the shaft body;

[0020] The second mounting plate is provided with a mounting plate gap extending radially along the second perforation and connecting the second perforation with the outside. The mounting plate gap divides part of the second mounting plate into a first bent plate and a second bent plate.

[0021] Furthermore, the first support plate is provided with a support plate through hole adapted to the shaft and a support gap extending along the radial direction of the support plate through hole and connecting the support plate through hole with the outside. The support gap divides the first support plate into a first support bending plate and a second support bending plate.

[0022] A refrigeration device, characterized in that it includes a housing, an inner liner disposed on the housing, an evaporator disposed within the inner liner, a heating wire, and a water collection tray assembly, wherein the water collection tray assembly is disposed below the evaporator.

This effectively prevents external heat from entering the cooling chamber through the drainage channel, reduces the heat loss of the evaporator, and improves the cooling efficiency.

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "left", "right", "top", "bottom", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Embodiments of the present invention: such as Figure 1-11 As shown, a drip tray assembly for refrigeration equipment is disclosed. The drip tray assembly can be used in refrigeration equipment such as refrigerators, freezers, and wine cabinets. The drip tray assembly is placed inside the refrigerator and located below the evaporator to collect the frost that falls off after the evaporator defrosts.

[0044] Specifically, the water receiving tray assembly for refrigeration equipment includes: a water receiving tray 1 and a cover assembly 2, including a tray body 11 with a water collection trough 10 and a drainage channel 12 communicating with the water collection trough 10, wherein the drainage channel 12 has a water inlet provided on the tray body 11;

[0045] The cap assembly 2 has a cap 21 rotatably mounted on the water receiving tray 1, and the size of the cap 21 is not larger than the size of the water inlet. The cap 21 has a capped state and a non-capped state.

[0046] When the cap is in the sealed state, the cap 21 is located above the water inlet and the plane of the cap 21 is 1-3 mm higher than the plane of the water inlet in the vertical direction;

[0047] When not covered, the cover 21 is positioned above the water inlet.

[0048] In this embodiment, the cover 21 in the cover assembly 2 is oscillatingly mounted on the water receiving tray 1. When not draining water, the cover 21 is located directly above the water inlet of the drainage channel 12, which can shield the drainage channel 12 and effectively prevent heat from entering the cooling chamber. At the same time, since the cover 21 is set 1-3mm above the plane where the water inlet is located, this structure can avoid interference during the oscillation of the cover 21. At the same time, this height also makes it easy to form a small gap. The small gap makes it easy for ice to form between the cover 21 and the water receiving tray 1. The formation of ice can further block the drainage channel 12, thereby better preventing external heat from entering the cooling chamber and affecting the evaporator in the cooling chamber.

[0049] During the defrosting and de-icing process, as the frost falls onto the water collection tray 1, it pushes the cover 21 as the bottom of the tray moves, thereby opening the drainage channel 12. Since the cover 21 and the water collection tray 1 are simply connected by ice, this connection is inherently unstable. Therefore, the cover 21 can be easily opened with a small amount of external force, thus facilitating the connection between the drainage channel 12 and the outside world for drainage.

[0050] In the scheme disclosed in this embodiment, by setting the cover 21 at a height of 1-3mm directly above the water receiving tray 1, an ice seal can be formed more quickly between the cover 21 and the water receiving tray 1 without affecting the swing of the cover 21. The cover 21 and the ice seal seal the drain channel 12, thereby achieving the sealing of the drain channel 12 without defrosting or de-icing. This effectively prevents external heat from entering the cooling chamber through the drain channel 12, reduces the heat loss of the evaporator, and improves the cooling efficiency.

[0051] Specifically, such as Figure 7-9 As shown, the cap assembly 2 also has a support frame 22 disposed on the disc body 11 and a rotating arm 23 disposed on the cap 21. The rotating arm 23 is rotatably mounted on the support frame 22 via a rotating shaft 24. The cap 21 swings on the disc body 11 through the cooperation of the rotating arm 23 and the support frame 22.

[0052] To improve the stability of the rotation of the cover 21, two rotating arms 23 are provided, symmetrically arranged on opposite sides of the cover 21. A rotating shaft 24 is positioned between the two rotating arms 23 and is rotatably connected to the support frame 22. The rotating arms 23 are vertically mounted on the cover 21, and both arms are located on the same side of the cover 21. The rotating arms 23 are connected to the support frame 22 via the rotating shaft 24. Alternatively, the rotating arms 23 can be fixedly connected to the rotating shaft 24, and the rotating shaft 24 can be rotatably mounted on the support frame 22; or the rotating arms 23 can be rotatably connected to the rotating shaft 24, and the rotating shaft 24 can be fixed to the support frame 22; or the rotating arms 23 can be rotatably connected to the rotating shaft 24, and the rotating shaft 24 can be rotatably mounted on the support frame 22.

[0053] In this embodiment, the projection of the rotating shaft 24 onto the plane of the cover 21 is located on the central axis of symmetry of the cover 21, so that the cover 21 moves to the covered state under its own gravity. This structure positions the cover 21 directly below the rotating shaft 24, and the projection of the rotating shaft 24 onto the plane of the cover 21 bisects the cover 21. Thus, when the rotating shaft 24 is rotatably mounted on the support frame 22, the cover 21 naturally droops under gravity, and the naturally drooping cover 21 is positioned directly above the drainage channel 12, thereby covering and sealing the drainage channel 12. This structure facilitates the closing of the cover 21.

[0054] In this embodiment, as Figure 1-3 As shown, the disc body 11 has an overall conical structure, and the water inlet of the drainage channel 12 is located at the lowest part of the conical structure. This structure facilitates the accumulation of frost in the drainage channel 12. The cross-section of the disc body 11 is approximately rectangular. Therefore, the water receiving tray 1 has a length direction and a width direction. The length direction is the left-right direction, and the width direction is the front-back direction. The specific shape of the disc body 11 is adapted to the shape of the evaporator. Existing evaporators have a rectangular cross-section and extend along the left-right direction.

[0055] The conical structure of the disc 11 is asymmetrical, meaning the lowest point of the cone is not at the center of the disc 11. The water inlet is located off-center from the center of the receiving tray 1 along its length. In this embodiment, the water inlet is positioned slightly to the left in the left-right direction. This results in two different slopes at the bottom of the disc 11: a first slope 111 and a second slope 112, where the slope of the first slope 111 is greater than that of the second slope 112. This structure ensures that the flow velocity is inconsistent on both sides when the water converges towards the drainage channel 12, preventing the water from colliding at the inlet of the drainage channel 12 and causing drainage problems. Furthermore, the different dimensions of the first slope 111 and the second slope 112 result in different water concentrations on them, further improving the flow rate asymmetry when the water converges towards the drainage channel 12.

[0056] To better facilitate the opening of the cover 21, the rotating shaft 24 extends along the width direction (not shown in the figure). Extending the rotating shaft 24 along the width direction allows the cover 21 to swing left and right along its length. Since the first slope bottom surface 111 and the second slope bottom surface 112 corresponding to the left and right directions of the cover 21 are asymmetrical, the flow rate and velocity of the water collected on the first slope bottom surface 111 are different from those on the second slope bottom surface 112. This results in different impacts from the water flow on the left and right sides of the cover 21, making it easier to drive the cover 21 during the defrosting process of the evaporator, thereby opening the drain channel 12. Figure 3 The described embodiment is an example in which the rotating shaft extends along its length. Figure 3 The proposed solution is not conducive to opening the cap 21. The preferred solution would be... Figure 3 The rotating shaft is rotated 90° to extend the rotating shaft along the width direction.

[0057] In this embodiment, as Figure 11 As shown, the support frame 22 includes a first support plate 221 and a second support plate 222 disposed on opposite sides of the water inlet, and the rotating arm 23 includes a first support arm and a second support arm disposed on opposite sides of the cover 21 and perpendicular to the cover 21.

[0058] The first support arm is rotatably mounted on the first support plate 221 via a rotating shaft 24, and the second support arm is rotatably mounted on the second support plate 222 via the same rotating shaft 24. Rotating the rotating shaft 24 on both the first and second support plates 221 allows for more stable rotation of the rotating shaft 24.

[0059] The first support arm and the second support arm have the same structure. In this embodiment, the first support arm will be used as an example for detailed description.

[0060] The first support arm includes a first mounting plate 231, a second mounting plate 232, and a connecting plate 233 connecting the first mounting plate 231 and the second mounting plate 232, which are disposed opposite to each other on the first support plate 221. The first mounting plate 231 and the second mounting plate 232 are both parallel to the first support plate 231, and the first mounting plate 231, the second mounting plate 232, and the connecting plate 233 form a downward-facing receiving groove 230. The first support plate 231 is adapted to and positioned within the receiving groove 230. The second mounting plate 232 is disposed opposite to the outside of the first support plate 231, with the outside of the first support plate 231 being the side opposite to the second support plate 222.

[0061] The above structure allows the first mounting plate 231 and the second mounting plate 232 to be positioned opposite each other on the opposite sides of the first support plate 231, thereby limiting the sealing assembly 2 in the left and right directions and better achieving the installation and fixation of the sealing cover 21.

[0062] like Figure 6 As shown, the rotating shaft 24 has a shaft body 241 and limiting rings 242 disposed on opposite sides of the shaft body 241. The cross-sectional dimension of the limiting rings 242 is larger than the cross-sectional dimension of the shaft body 241.

[0063] like Figure 8 As shown, the first mounting plate 231 is provided with a first through hole 2310 that is adapted to the limiting ring 242, and the second mounting plate 232 is provided with a second through hole 2320 that is adapted to the shaft 241.

[0064] like Figure 7-10 As shown, the second mounting plate 232 is provided with a mounting plate gap 2321 extending radially along the second through hole 2320 and connecting the second through hole 2320 with the outside. The mounting plate gap 2321 divides part of the second mounting plate 232 into a first bent plate 2322 and a second bent plate 2323. The size of the mounting plate gap 2321 is smaller than the size of the second through hole 2320, and the size of the mounting plate gap 2321 is smaller than the cross-sectional size of the shaft 241.

[0065] The first bending plate 2322 and the second bending plate 2323 can be bent, which facilitates opening the second through hole 2320 and increases the width of the mounting plate gap 2321. The increase in the size of the mounting plate gap 2321 also increases the size of the second through hole 2320, making it easier for the limiting ring 242 to pass through the second through hole 2320. After the limiting ring passes through 242, the shaft 241 is located inside the second through hole 2320. At this time, the limiting ring 242 is bent back to its initial state, which reduces the size of the second through hole 2320 so that the size of the second through hole 2320 matches that of the shaft 241. The limiting ring 242 abuts against the outside of the second mounting plate 232. The second through hole 2320 is set to restrict the passing of the limiting ring 242, thereby facilitating the installation and fixation of the rotating shaft 24.

[0066] During the installation and fixing process of the rotating shaft 24, the first bending plate 2322 and / or the second bending plate 2323 are first bent to both sides along the gap 2321 of the mounting plate, thereby opening the second through hole 2320. After the second through hole 2320 is opened, the second through hole 2320 is enlarged to facilitate the insertion of the limiting ring 242 through the second through hole 2320. After the limiting ring 242 is inserted through the second through hole 2320, the first bending plate 2322 and the second bending plate 2323 are reset and bent so that the second through hole 2320 returns to its original position. At this time, the limiting ring 242 abuts against the second mounting plate 232. The second mounting plate 232 provides axial limiting for the rotating shaft 24. Both ends of the rotating shaft 24 are limited by the corresponding second mounting plates, thereby achieving limiting in its axial extension direction.

[0067] After the rotating shaft 24 and the rotating arm 23 are installed and fixed, the rotating shaft 24 also needs to be installed on the first support plate 221 and the second support plate 222. In order to facilitate the installation and fixation of the rotating shaft 24 with the first support plate 221 and the second support plate 222, the first support plate 221 is provided with a support plate through hole 2210 that is adapted to the shaft body 241 and a support gap 2211 that extends along the radial direction of the support plate through hole 2210 and connects the support plate through hole 2210 with the outside. The support gap 2211 divides the first support plate 221 into a first support bending plate 2212 and a second support bending plate 2213.

[0068] When the rotating shaft 24 is installed and fixed to the first support plate 221, the first support bending plate 2212 and / or the second support bending plate 2213 are first bent to both sides along the support gap 2211, thereby opening the support plate through hole 2210. After the support plate through hole 2210 is opened, the size of the support gap 2211 is increased to facilitate the insertion of the shaft 241. After the shaft 241 passes through the support gap 2211 and enters the support plate through hole 2210, the first support bending plate 2212 and the second support bending plate 2213 are bent back to their original positions, so that the support gap 2211 is restored to its original position, thus achieving the installation and fixation of the rotating shaft 24 on the first support plate 221. The above structure facilitates the installation and fixation of the rotating shaft 24.

[0069] In another embodiment, a refrigeration device is disclosed, which may be a refrigerator or a freezer. Specifically, the refrigeration device includes a cabinet, an inner liner disposed on the cabinet, an evaporator disposed in the inner liner, a heating wire, and a water tray assembly, wherein the water tray assembly is disposed on the lower side of the evaporator.

[0070] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
