Description

Technical Field

[0001] The present application relates to the technical field of refrigeration, for example, to a refrigeration device. Background Art

[0002] At present, in current commercial freezers on the market, the basic solution is to place the evaporator on the step. In this solution, the drainage is from high to low, basically vertical, and relatively smooth. However, in some scenarios, such as commercial freezers, more attention is paid to the display volume of the top space. At this time, the solution of placing the evaporator compartment under the step becomes more in demand, but the drainage can only be side drainage.

[0003] A related art discloses a freezer, which includes a cabinet shell and an inner liner. The inner liner is disposed inside the cabinet shell and includes a first bottom wall, a second bottom wall, and a sunken structure disposed between the first bottom wall and the second bottom wall. The second bottom wall is higher than the first bottom wall, and the bottom wall of the sunken structure is lower than the first bottom wall; an evaporator compartment is disposed in the sunken structure, and a blower is arranged inside.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] The freezer in the related art is provided with a sunken structure. If the drainage port is to maintain an effective drainage angle to the compressor compartment, the foaming layer at the bottom of the inner liner will be relatively thick, wasting the internal space. If the bottom foaming layer remains at a normal level, the drainage angle will be relatively small, with a risk of icing.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0058] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0059] For the sake of convenience of description, the front, rear, left, right, upper and lower directions of this application are as Figure 1 、 Figure 12 and Figure 16 shown by the arrows.

[0060] Combined with Figures 1 to 26 shown, the embodiments of the present disclosure provide a refrigeration device, which includes a box shell and an inner liner 10. The box shell is sleeved on the outside of the inner liner 10, and a foaming layer is filled between the box shell and the inner liner 10. The inner liner 10 defines a storage space for placing items.

[0061] Optionally, the refrigeration device includes a refrigeration system, which includes a compressor, a condenser, a throttling device and an evaporator 206 that are sequentially connected through a refrigerant pipeline. The compressor, the condenser and the throttling device are located between the inner liner 10 and the box shell, and the evaporator 206 is arranged inside the inner liner 10.

[0062] Optionally, the refrigeration device is an air-cooled refrigeration device, and the refrigeration device further includes an evaporation fan. The inner container 10 defines an evaporator compartment and a compressor compartment 107. The compressor compartment 107 is located between the inner container 10 and the cabinet shell, and the evaporator compartment is located inside the inner container 10. The evaporator 206 is located in the evaporator compartment, and the compressor is located in the compressor compartment 107. The evaporation fan is communicated with the evaporator compartment. The evaporation fan can drive the air flow in the storage space to flow into the evaporator compartment. After the air flow exchanges heat with the evaporator 206 and cools down, it flows back into the storage space to realize air-cooled refrigeration of the storage space.

[0063] Optionally, the refrigeration device is a cold cabinet, a freezer, etc. Specifically, the refrigeration device can be a horizontal cold cabinet, especially a horizontal air-cooled cold cabinet.

[0064] Optionally, the side wall of the inner container 10 is configured with an air duct and an air outlet. The air duct communicates the storage space and the evaporator compartment. The evaporation fan can drive the air flow in the evaporator compartment to flow into the air duct, and then flow into the storage space from the air outlet of the air duct. The evaporator compartment or the air duct is provided with an air return opening. The air flow that releases cold in the storage space flows into the evaporator compartment through the air return opening, thereby realizing the circulation of the air path.

[0065] Optionally, the inner container 10 includes a vertically arranged vertical side wall. The vertical side wall connects the bottom wall of the evaporator compartment and the top wall of the compressor compartment 107 of the refrigeration device. The vertical side wall separates the evaporator compartment and the compressor compartment 107. The refrigeration device further includes an evaporation fan. The evaporation fan is vertically arranged on the bottom wall of the evaporator compartment. The evaporation fan includes a volute. Among them, the top wall of the evaporator compartment is flush with the top wall of the compressor compartment 107. The height difference between the highest point of the drainage surface 103 where the evaporation fan is located and the top wall of the evaporator compartment is equal to the height of the volute.

[0066] The top wall of the evaporator compartment is flush with the top wall of the compressor compartment 107. In this way, the appearance is more beautiful, and it is more convenient to place things on the top wall surface of the evaporator compartment and the top wall surface of the compressor compartment 107. Assuming that the evaporation fan is arranged on the drainage surface 103 and the height of the volute is equal to the height difference between the highest point of the drainage surface 103 and the top wall of the evaporator compartment, in this way, the evaporation fan can be vertically placed and will not protrude from the top wall of the evaporator compartment, ensuring that the top wall of the evaporator compartment is always flush with the top wall of the compressor compartment 107 and improving the aesthetics. Moreover, the evaporation fan is vertically placed, the air outlet resistance of the cold air is small, the air volume is large, and the refrigeration effect of the refrigeration device is better.

[0067] Optionally, the bottom wall of the evaporator compartment includes a drainage surface 103 and a drainage port 104. The drainage port 104 is located at the lowest point of the drainage surface 103. The drainage port 104 is located at the lowest point of the drainage surface 103. The drainage surface 103 is inclined towards the drainage port 104 so that the water on the drainage surface 103 can flow to the drainage port 104 and flow out.

[0068] Optionally, as Figure 1 、Figure 16 As shown, the drain opening 104 is located at one end of the drain surface 103 in the left - right direction, which facilitates the external connection of the drain pipe to the drain opening 104 and also facilitates the arrangement of the drain pipe.

[0069] Optionally, the compressor compartment 107 includes a drain pipe and an evaporation dish. One end of the drain pipe is connected to the drain opening 104, and the other end is connected to the evaporation dish, draining the defrost water in the evaporator compartment into the evaporation dish.

[0070] Optionally, the compressor compartment 107 and the evaporator compartment are arranged side - by - side in the left - right direction, and the drain opening is located at the end of the drain surface 103 close to the compressor compartment 107. In this way, the defrost water in the evaporator compartment flows into the drain pipe in the compressor compartment 107 through the drain opening 104, and then flows into the evaporation dish for evaporation.

[0071] Optionally, as Figure 1 、 Figure 7 、 Figure 16 shown, the bottom wall of the inner container 10 includes a connected first bottom wall 101 and a second bottom wall 102. The second bottom wall 102 is configured with a drain surface 103 and a drain opening 104; the evaporator 206 is arranged above the second bottom wall 102; wherein, the second bottom wall 102 is higher than the first bottom wall 101.

[0072] In the embodiment of the present disclosure, the evaporator 206 is located above the second bottom wall 102, and the second bottom wall 102 is higher than the first bottom wall 101. In this way, the first bottom wall 101 is used to place items, and the second bottom wall 102 is used to place the evaporator 206. The defrost water generated when the evaporator 206 defrosts can flow to the drain surface 103 of the second bottom wall 102, and then flow along the drain surface 103 to the drain opening 104 and flow out. Since the drain surface 103 needs to be inclined towards the drain opening 104, therefore, the drain surface 103 needs to occupy a certain space in the height direction. In the embodiment of the present disclosure, the second bottom wall 102 provided with the drain surface 103 is set higher than the first bottom wall 101, so that the entire inner container 10 does not occupy the space of the foam layer, and there is no need to increase the thickness of the foam layer to ensure the refrigeration effect. Moreover, without changing the thickness of the foam layer, the inclination angle of the drain surface 103 can be ensured to guarantee the drainage rate and effect.

[0073] It can be understood that the second bottom wall 102 can be entirely higher than the first bottom wall 101, or partially higher than the first bottom wall 101.

[0074] Optionally, the inner container 10 further includes a connecting side wall 105, which is connected between one end of the first bottom wall 101 and the end of the second bottom wall 102 far from the drain opening 104 and extends in the vertical direction, so that the end of the second bottom wall 102 far from the drain opening 104 is higher than the first bottom wall 101.

[0075] In the embodiments of the present disclosure, the connecting side wall 105 is connected between one end of the first bottom wall 101 and one end of the second bottom wall 102, so as to raise the height of one end of the second bottom wall 102, and one end of the second bottom wall 102 is far from the drain outlet 104, which facilitates the drainage surface 103 of the second bottom wall 102 to incline towards the drain outlet 104.

[0076] Optionally, the height difference range between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is 20 mm ≤ h ≤ 100 mm.

[0077] In the embodiments of the present disclosure, when the height difference between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is less than 20 mm, the height difference is too small, which may cause insufficient angle of the drainage surface 103 or may cause one end of the second bottom wall 102 close to the drain outlet 104 to be lower than the first bottom wall 101, and further may cause an increase in the required thickness of the foaming layer, increasing the cost. When the height difference between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is greater than 100 mm, it may cause the height of the evaporator 206 to be too high, reducing the volume of the storage space.

[0078] Optionally, the height difference range between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is 20 mm ≤ h ≤ 50 mm. In the embodiments of the present disclosure, when the height difference between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is within this range, it can neither increase the thickness of the foaming layer nor ensure the drainage angle.

[0079] Exemplarily, the height difference between one end of the second bottom wall 102 far from the drain outlet 104 and the first bottom wall 101 is 20 mm, 25 mm, 28 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm or 100 mm, etc.

[0080] Optionally, the drain outlet 104 is located at the end of the second bottom wall 102 far from the first bottom wall 101.

[0081] In the embodiments of the present disclosure, the drain outlet 104 is located at the end of the second bottom wall 102, so that the distance from the first bottom wall 101 to the drain outlet 104 of the second bottom wall 102 is sufficient, which can increase the setting length and inclination angle of the drainage surface 103 in the left - right direction.

[0082] Optionally, the lowest point of the drain outlet 104 is flush with or higher than the first bottom wall 101.

[0083] In the embodiments of the present disclosure, the lowest point of the drain opening 104 is not lower than the first bottom wall 101, so that the second bottom wall 102 around the drain opening 104 does not occupy the space of the foaming layer, and thus there is no need to adjust the thickness of the foaming layer, and the drainage angle can be ensured.

[0084] Optionally, the drainage surface 103 includes a first drainage surface 20. The first drainage surface 20 is located on one side of the drain opening 104. One end of the first drainage surface 20 is connected to the first bottom wall 101 and one end of the first drainage surface 20 is higher than the second bottom wall 102. The other end of the first drainage surface 20 is connected to the drain opening 104. Along the direction from one end of the first drainage surface 20 to the other end of the first drainage surface 20, the first drainage surface 20 slopes downward.

[0085] In the embodiments of the present disclosure, the first drainage surface 20 is connected between the first bottom wall 101 and the drain opening 104, and the first drain opening 104 slopes from the first bottom wall 101 towards the drain opening 104. In this way, when the defrosting water of the evaporator 206 flows to the first drainage surface 20, the defrosting water will flow along the first drainage surface 20 to the drain opening 104 to improve the drainage efficiency.

[0086] Optionally, the included angle a between the first drainage surface 20 and the horizontal direction is greater than or equal to 3°.

[0087] In the embodiments of the present disclosure, when the included angle between the first drainage surface 20 and the horizontal direction is less than 3°, the inclination angle of the first drainage surface 20 is too small, resulting in insufficient drainage angle and incomplete drainage.

[0088] Optionally, the drainage surface 103 further includes a second drainage surface 201. One end of the second drainage surface 201 is connected to the front side wall or the rear side wall of the inner container 10, and the other end of the second drainage surface 201 is connected to the first drainage surface 20. The second drainage surface 201 slopes downward in the front-rear direction along the direction close to the drain opening 104.

[0089] In the embodiments of the present disclosure, the second drainage surface 201 is connected between the front side wall or the rear side wall of the inner container 10 and the first drainage surface 20, and the second drainage surface 201 also slopes downward in the front-rear direction along the direction close to the drain opening 104. In this way, for the water flowing along the second drainage surface 201 in the front-rear direction, a part of the water can flow to the position of the first drainage surface 20 lower than the second drainage surface 201, and another part of the water can directly flow to the drain opening 104 along the position of the second drainage surface 201 close to the drain opening 104. In this way, the defrosting water flowing to the second drainage surface 201 can flow along the second drainage surface 201 to the first drainage surface 20 or flow to the drain opening 104 and flow out.

[0090] In addition, by designing the drainage surfaces 103 in multiple numbers, the position of the drain opening 104 can be adjusted through the connection positions of the multiple drainage surfaces 103 to meet various product requirements. Moreover, compared with the bottom wall formed by a single drainage surface 103 that slopes downward in a direction from back to front, from front to back, from left to right, or from right to left, when the inclination angles and directions of the first drainage surface 20 or the second drainage surface 201 are the same as those of the single drainage surface 103, the lowest point of the bottom wall formed by the first drainage surface 20 and the second drainage surface 201 is higher than the lowest point of the single drainage surface 103, which can occupy less heat-insulating layer and the heat-insulating effect of the refrigeration equipment is better.

[0091] Optionally, the included angle b between the second drainage surface 201 and the horizontal direction is less than or equal to 10°.

[0092] In the embodiment of the present disclosure, when the included angle b between the second drainage surface 201 and the horizontal direction is greater than 10°, it will cause the inclination angle of the second drainage surface 201 to be too large, which is not convenient for the stable placement of the evaporator 206, and will also occupy the space of the foaming layer, resulting in an increase in the thickness of the foaming layer and an increase in cost.

[0093] Optionally, in the left-right direction, along the direction close to the drain opening, the first drainage surface slopes downward, and the distance between the two side edges of the first drainage surface in the front-back direction gradually decreases, so that the water on the first drainage surface can converge and flow to the drain opening and flow out from the drain opening.

[0094] Optionally, when the number of the second drainage surfaces 201 is multiple, the multiple second drainage surfaces 201 include a front drainage surface 203 and a rear drainage surface 204, the first drainage surface 20 is located between the front drainage surface 203 and the rear drainage surface 204. When the front drainage surface 203 is connected to the front side wall of the inner container 10, the front drainage surface 203 slopes downward in the front-to-back direction, and one end of the front drainage surface 203 away from the front side wall forms a first hypotenuse. The multiple second drainage surfaces 201 further include a rear drainage surface 204. When the rear drainage surface 204 is connected to the rear side wall of the inner container 10, the rear drainage surface 204 slopes downward in the back-to-front direction, and one end of the rear drainage surface 204 away from the rear side wall forms a second hypotenuse. Wherein, the first drainage surface 20 is connected between the first hypotenuse and the second hypotenuse, and along the direction close to the drain opening 104, the distance between the first hypotenuse and the second hypotenuse gradually decreases, and the drain opening 104 is arranged at the intersection of the first hypotenuse, the second hypotenuse and the first drainage surface 20.

[0095] In the embodiments of the present disclosure, the rear drainage surface 204 slopes downward in the direction from the rear to the front, and the front drainage surface 203 slopes downward in the direction from the front to the rear. Therefore, the first hypotenuse and the second hypotenuse are the lowest edges of the front drainage surface 203 and the rear drainage surface 204. The intersection of the first hypotenuse, the second hypotenuse, and the first drainage surface 20 is the lowest point of the drainage surface 103. Setting the drain port 104 at the lowest point can make the drainage process of the defrosting water in the evaporator chamber smoother, improve the drainage effect of the evaporator chamber, and further ensure the normal operation of the evaporator 206, thereby ensuring the refrigeration effect of the refrigeration equipment. Moreover, the structure of this double drainage surface 103 is simple and cost-saving.

[0096] Optionally, the bottom wall of the evaporator chamber includes a second bottom wall 102, and the first bottom wall 101 is connected to one end of the second bottom wall 102 facing away from the compressor chamber 107.

[0097] Optionally, along the left-right direction, the second drainage surface 201 slopes downward in the direction towards the drain port.

[0098] In this way, the drainage of the second drainage surface 201 can flow into the drain port.

[0099] Optionally, when the drain port is located on the side of the evaporator chamber close to the compressor chamber, the second drainage surface 201 slopes downward in the left-right direction towards the compressor chamber 107.

[0100] In the embodiments of the present disclosure, the second drainage surface 201 slopes downward in the left-right direction towards the compressor chamber 107, so that one end of the second drainage surface 201 is close to the drain port 104. In this way, the water on the second drainage surface 201 not only flows forward or backward to the first drainage surface 20, but also flows in the left-right direction towards the drain port 104 of the compressor chamber 107.

[0101] Optionally, when the second drainage surface 201 includes a front drainage surface 203 and a rear drainage surface 204, both the front drainage surface 203 and the rear drainage surface 204 slope downward in the left-right direction towards the compressor chamber 107. In this way, the lowest point of the first hypotenuse or the second hypotenuse is exactly close to one end of the compressor chamber 107. The drain port 104 is provided at the lowest point of the lowest edge of the bottom wall of the evaporator chamber, which can make the drainage process of the defrosting water in the evaporator chamber smoother, improve the drainage effect of the evaporator chamber, and further ensure the normal operation of the evaporator 206, thereby ensuring the refrigeration effect of the refrigeration equipment.

[0102] Optionally, the first drainage surface 20 is triangular, with the base of the triangle located on the side of the evaporator compartment facing away from the compressor compartment 107 and the apex angle located on the side of the evaporator compartment close to the compressor compartment 107. The first drainage surface 20 slopes in the direction from the base of the triangle towards the apex angle. Among them, the drainage port 104 is provided at the apex angle of the triangle. In this way, the triangular first drainage surface 20 slopes downward in the left-right direction towards the compressor compartment 107.

[0103] Optionally, the evaporator 206 is horizontally placed in the evaporator compartment. This can reduce the height of the evaporator compartment and increase the volume of the storage space.

[0104] In some alternative embodiments, as Figures 1 to 6 shown, at least three points on the evaporator 206 are respectively in contact with the first drainage surface 20, the front drainage surface 203, and the rear drainage surface 204 to support the evaporator 206.

[0105] In this way, the evaporator 206 can be stably supported without the need for additional brackets, and the horizontal placement of the evaporator 206 can be achieved, minimizing the obstruction of the evaporator 206 to the flow path of the defrost water, and the drainage of the evaporator compartment is smoother.

[0106] Optionally, the drainage surface 103 further includes a fourth drainage surface 205. The fourth drainage surface 205 is provided between the first drainage surface 20 and the second drainage surface 201. The first end of the fourth drainage surface 205 is connected to the second drainage surface 201, and the second end of the fourth drainage surface 205 is connected to the first drainage surface 20. The first end of the fourth drainage surface 205 is higher than the second end of the fourth drainage surface 205, and along the direction from the first end to the second end of the fourth drainage surface 205, the fourth drainage surface slopes downward. The fourth drainage surface 205 and the first drainage surface 20 jointly define a drainage portion, and the drainage port 104 is located at the lowest point of the drainage portion.

[0107] The first end of the fourth drainage surface 205 is higher than the second end of the fourth drainage surface 205, that is, the fourth drainage surface 205 extends along the up-down direction. The second drainage surface 201 is higher than the first drainage surface 20. In this way, the defrost water at the lowest point of the second drainage surface 201 can smoothly flow into the drainage portion through the fourth drainage surface 205, reducing water accumulation. The defrost water in the evaporator compartment first flows into the drainage portion and then flows out of the evaporator compartment through the drainage port 104, avoiding the problem of water accumulation and icing on the side of the second drainage surface 201 close to the compressor compartment 107.

[0108] Optionally, along the front-rear direction, the inclination angle of the fourth drainage surface 205 is greater than the inclination angle of the second drainage surface. In this way, the water flowing from the second drainage surface to the fourth drainage surface 205 can accelerate and flow to the drainage portion, improving the drainage speed.

[0109] Optionally, the number of the fourth drainage surfaces 205 is two, and the two fourth drainage surfaces 205 are respectively arranged on both sides of the first drainage surface 20 in the front-back direction. The two fourth drainage surfaces 205 and the first drainage surface 20 enclose a drainage part, and the drainage port 104 is located at the lowest point of the drainage part.

[0110] Optionally, the evaporator 206 is placed in contact with the second drainage surface 201 and is located above the drainage part.

[0111] In this way, the evaporator 206 has a high degree of contact with the second drainage surface 201. During the return air process of the refrigeration device, the utilization rate of the evaporator 206 is higher and the power consumption is low. The evaporator 206 is arranged above the drainage part, so that the water vapor attached to the surface of the part of the evaporator 206 above the drainage part can directly drip into the drainage part and be discharged from the evaporator compartment through the drainage port 104, improving the drainage efficiency.

[0112] In some alternative embodiments, the number of the drainage surfaces 103 is one, and the drainage port 104 is located at the end corner of the drainage surface 103.

[0113] The number of the drainage surfaces 103 is one. The bottom wall of the evaporator compartment, that is, the second bottom wall 102, is only composed of one drainage surface 103. The structure is simple, the process difficulty is reduced, and the cost is saved. Assume that the single drainage surface 103 slopes downward in the direction from back to front and slopes to the right in the direction from left to right. Then, the lowest point of the single drainage surface 103 is at the end corner in its right front. Setting the drainage port 104 here can meet the requirement that the drainage port 104 is lower than any point on the single drainage surface 103.

[0114] Optionally, the refrigeration device further includes a protrusion, which is arranged on the drainage surface and protrudes upward from the drainage surface. The protrusion supports below the evaporator to make the evaporator inclined or horizontal.

[0115] In the embodiments of the present disclosure, a protrusion is arranged above the drainage surface, and the protrusion can support the evaporator. By setting the protrusion, the inclination angle of the evaporator can be readjusted. The overall inclination angle of the drainage surface does not need to be set too large. The cooperation of the inclined drainage surface and the protrusion can increase the drainage angle of the evaporator, ensure drainage, and does not occupy the space of the foaming layer. In this way, the height of the volute of the evaporation fan arranged in the evaporator compartment can be reduced, and it is avoided that the volute of the evaporation fan is higher than the top of the compressor compartment, improving the integrity of the appearance.

[0116] In some other alternative embodiments, as Figures 16 to 26 shown, the refrigeration device includes a boss, which is arranged on the drainage surface 103 and protrudes upward from the drainage surface 103. The boss supports below the evaporator 206, and the defrosting water of the evaporator 206 can flow along the drainage surface 103 to the drainage port 104 for discharge. The protrusion includes the boss.

[0117] In the embodiments of the present disclosure, a boss is convexly provided on the drainage surface 103. The boss can lift the evaporator 206 and separate at least a part of the bottom of the evaporator 206 from the drainage surface 103. In this way, the defrost water of the evaporator 206 can flow onto the drainage surface 103, so that the defrost water flowing onto the drainage surface 103 has a certain initial velocity, which can increase the flow path, and then flow along the drainage surface 103 and then flow to the drainage port 104. In this way, it is not necessary to change the inclination angle of the drainage surface 103, nor to provide a sunken structure, which can ensure the thickness of the foaming layer between the inner container 10 and the cabinet shell, and can also ensure the adequacy of the drainage angle and the drainage efficiency.

[0118] In addition, due to the setting of the boss, the height difference of the drainage surface 103 will not be too large, and it is not necessary to raise the height of the drainage surface 103 too much. In this way, the evaporator 206 or the evaporation fan can be completely hidden in the evaporator compartment and will not expose the top wall of the compressor compartment 107, and the appearance integrity is better. The bottom of the evaporator 206 is spaced from the drainage surface 103, which can improve the thoroughness of drainage.

[0119] Optionally, the number of bosses is one.

[0120] Optionally, the number of bosses is multiple. The multiple bosses include a first boss 40 and a second boss 50. The first boss 40 and the second boss 50 are sequentially spaced at intervals in the left-right direction, so that the defrost water of the evaporator 206 flows along the drainage surface 103 to the drainage port 104 and is discharged.

[0121] In the embodiments of the present disclosure, the first boss 40 and the second boss 50 are sequentially spaced at intervals in the left-right direction, which can improve the support stability of the first boss 40 and the second boss 50 for the evaporator 206. Moreover, the setting of the two bosses can support the evaporator 206 in the left-right direction, so that the evaporator 206 can adjust the placement angle, thereby improving the drainage smoothness of the evaporator 206.

[0122] Optionally, the drainage port 104 is provided on one side of the bottom wall of the evaporator compartment in the left-right direction. That is to say, the first drainage surface 20 slopes downward in the direction close to the drainage port 104 in the left-right direction. The first boss 40 is located on the first drainage surface 20, and the first boss 40 is located in front of or behind the drainage port 104. The second boss 50 corresponds to the first boss 40 in the left-right direction.

[0123] In the embodiment of the present disclosure, the first boss 40 is provided on the first drainage surface 20, so that at least part of the defrost water of the evaporator 206 can flow to the first drainage surface 20, and then flow along the first drainage surface 20 towards the drain opening 104. The second boss 50 corresponds to the first boss 40 in the left-right direction, so that the evaporator 206 can be evenly stressed, enabling the evaporator 206 to be stably placed. And there is a gap between the position of the evaporator 206 between the first boss 40 and the second boss 50 and the drainage surface 103, so that there can be a gap between the bottom of the evaporator 206 and the water receiving surface, enabling the defrost water of the evaporator 206 to flow to the drainage surface 103, having a certain acceleration, and then flowing along the drainage surface 103 to the drain opening 104.

[0124] Optionally, the second boss 50 straddles above the first drainage surface 20 and the second drainage surface 201.

[0125] In the embodiment of the present disclosure, the second boss 50 straddles above the first drainage surface 20 and the second drainage surface 201, which can not only ensure the inclined setting of the first drainage surface 20 and the second drainage surface 201, but also use the second boss 50 to readjust the inclination angle of the evaporator 206. Without raising the heights of the second drainage surface 201 and the first drainage surface 20, the height difference between the first drainage surface 20 and the second drainage surface 201 can also be reduced, and the height of the evaporator compartment can be reduced.

[0126] Optionally, the first boss 40 includes a first support surface 401, and the second boss 50 includes a second support surface 501. When the evaporator 206 is located above the first boss 40 and the second boss 50, the evaporator 206 is in contact with both the first support surface 401 and the second support surface 501.

[0127] In the implementation of the present disclosure, the evaporator 206 is in contact with both the first support surface 401 and the second support surface 501, which can increase the contact area between the first boss 40 and the second boss 50 and the evaporator 206, thereby improving the setting stability of the evaporator 206.

[0128] Optionally, the first boss further includes a first support side wall, the first support side wall is connected between the end of the first support surface and the drainage surface, and along the direction from top to bottom, the first support side wall is inclined away from the first support surface; and / or, the second boss further includes a second support side wall, the second support side wall is connected between the end of the second support surface and the drainage surface, and along the direction from top to bottom, the second support side wall is inclined away from the second support surface.

[0129] In the embodiments of the present disclosure, the first support surface of the first boss is located at the top of the first boss. The first boss is connected between the first support surface and the drainage surface through the first support side wall, and the first support side wall is inclined. In this way, the defrost water on the first support surface can flow downward along the first support side wall and away from the first boss, improving the drainage efficiency. Similarly, the second support surface of the second boss is located at the top of the second boss. The second boss is connected between the second support surface and the drainage surface through the second support side wall, and the second support side wall is inclined. In this way, the defrost water on the second support surface can flow downward along the second support side wall and away from the second boss, improving the drainage efficiency.

[0130] Optionally, the number of the first support side walls is multiple, and the multiple first support side walls are sequentially arranged along the circumference of the first support surface.

[0131] Optionally, the number of the second support side walls is multiple, and the multiple second support side walls are sequentially arranged along the circumference of the second support surface.

[0132] In some alternative embodiments, as Figures 16 to 19 shown, the first support surface 401 and the second support surface 501 extend horizontally and are in the same horizontal plane, so that the evaporator 206 is horizontally arranged on the drainage surface 103.

[0133] In the embodiments of the present disclosure, both the first support surface 401 and the second support surface 501 extend in the horizontal direction and are in the same horizontal plane. In this way, the evaporator 206 can be horizontally placed, and the evaporator is stably placed. In this way, the height of the evaporator 206 can be reduced, and then the height of the evaporator compartment or the volute of the evaporation fan can be reduced, avoiding the exposure of steps. Moreover, a part of the defrost water of the evaporator 206 can flow along the first support surface 401 and the second support surface 501 to the drainage surface 103 and then be discharged to the drainage port 104, and another part of the defrost water can directly flow to the drainage surface 103 between the first boss 40 and the second boss 50 and then be discharged from the drainage port 104.

[0134] Optionally, the first boss 40 includes a first side wall 402, a second side wall 403, and a third side wall 404. The first side wall 402, the second side wall 403, and the third side wall 404 are connected between a first support surface 401 and a first drainage surface 20. Among them, the first end of the first support surface 401 abuts against the first drainage surface 20, the second end of the first support surface 401 is connected to the first side wall 402, the first end and the second end of the first support surface 401 are arranged in the left-right direction, and the first support surface 401 extends horizontally in the left-right direction through the arrangement of the first side wall 402. The third end and the fourth end of the first support surface 401 are arranged in the front-back direction. The second side wall 403 is connected between the third end of the first support surface 401 and the first drainage surface 20, and the third side wall 404 is connected between the fourth end of the first support surface 401 and the first drainage surface 20. In the left-right direction, along the direction close to the drain opening 104, the heights of the second side wall 403 and the third side wall 404 gradually increase, so that the first support surface 401 extends horizontally in the left-right direction, where the first support side wall includes the first side wall 402, the second side wall 403, and the third side wall 404.

[0135] Optionally, the second boss 50 includes a fourth side wall 502, a fifth side wall 503, and a sixth side wall 504. The first end and the second end of the second support surface 501 are arranged in the left-right direction, and the third end and the fourth end of the second support surface 501 are arranged in the front-back direction. The fourth side wall 502 straddles the first drainage surface 20 and the second drainage surface 201, and the fourth side wall 502 is connected between the first end of the second support surface 501 and the second drainage surface 201 and the first drainage surface 20. The second end of the second support surface 501 abuts against the side wall of the evaporator compartment facing the compressor compartment 107, so that the second support surface 501 extends horizontally in the left-right direction. The fifth side wall 503 is connected between the third end of the second support surface 501 and the first drainage surface 20, and the sixth side wall 504 is connected between the fourth end of the second support surface 501 and the second drainage surface 201. The top of the sixth side wall 504 is higher than the top of the fifth side wall 503, so that the second support surface 501 extends horizontally in the front-back direction, where the second support side wall includes the fourth side wall 502, the fifth side wall 503, and the sixth side wall 504.

[0136] In some other alternative embodiments, as Figures 20 to 24 shown, both the first support surface 401 and the second support surface 501 are inclined downward in the front-back direction toward the direction close to the drain opening 104, and the inclination directions and angles of the first support surface 401 and the second support surface 501 are the same, so that the evaporator 206 is inclined downward in the front-back direction toward the direction close to the drain opening 104.

[0137] In the embodiments of the present disclosure, the first support surface 401 and the second support surface 501 may be arranged to be inclined, and both the first support surface 401 and the second support surface 501 are inclined downward in the front-back direction. In this way, the evaporator 206 that fits with the first support surface 401 and the second support surface 501 is also inclined downward in the front-back direction toward the direction close to the drain port 104. Thus, the defrosting water flowing to the first support surface 401 and the second support surface 501 of the evaporator 206 can flow downward in the front-back direction under the guidance of the first support surface 401 and the second support surface 501. After flowing to the drainage surface 103, the distance from the drain port 104 can be reduced, the amount of water flowing to the drain port 104 can be increased, and thus the drainage effect can be improved.

[0138] Optionally, the first boss 40 includes a seventh side wall 405, an eighth side wall 406, and a ninth side wall 407. The seventh side wall 405, the eighth side wall 406, and the ninth side wall 407 are connected between the first support surface 401 and the first drainage surface 20. Among them, the first end of the first support surface 401 abuts against the first drainage surface 20, the second end of the first support surface 401 is connected to the seventh side wall 405, and the first end and the second end of the first support surface 401 are arranged in the left-right direction.

The eighth side wall 406 is connected between the third end of the first support surface 401 and the first drainage surface 20, and the ninth side wall 407 is connected between the fourth end of the first support surface 401 and the first drainage surface 20. In the left-right direction, along the direction close to the drain port 104, the first support surface 401 is inclined downward, where the first support side wall includes the seventh side wall 405, the eighth side wall 406, and the ninth side wall 407.

[0139] Optionally, the second boss 50 includes a tenth side wall 505, an eleventh side wall 506, and a twelfth side wall 507. The first end and the second end of the second support surface 501 are arranged in the left-right direction, and the third end and the fourth end of the second support surface 501 are arranged in the front-back direction. The tenth side wall 505 straddles the first drainage surface 20 and the second drainage surface 201, and the tenth side wall 505 is connected between the first end of the second support surface 501 and the second drainage surface 201 and the first drainage surface 20. The second end of the second support surface 501 abuts against the side wall of the evaporator compartment facing the compressor compartment 107. The eleventh side wall 506 is connected between the third end of the second support surface 501 and the first drainage surface 20, and the twelfth side wall 507 is connected between the fourth end of the second support surface 501 and the second drainage surface 201, so that the second support surface 501 is inclined downward in the front-back direction toward the direction close to the drain port 104, where the second support side wall includes the tenth side wall 505, the eleventh side wall 506, and the twelfth side wall 507.

[0140] Optionally, in the left - right direction, the first boss 40 is provided at the end of the drainage surface 103 away from the drain opening 104, and the second boss 50 is provided at the end of the drainage surface 103 close to the drain opening 104.

[0141] In the embodiment of the present disclosure, one end of the first boss 40 is close to the drainage surface 103, and the other end of the second boss 50 is close to the drainage surface 103. This can increase the distance between the first boss 40 and the second boss 50 in the left - right direction, thereby improving the support stability of the evaporator 206 and preventing the evaporator 206 from shaking.

[0142] Optionally, the second boss 50 abuts against the side wall of the compressor compartment 107 facing the evaporator compartment.

[0143] In the embodiment of the present disclosure, the second boss 50 abuts against the side wall of the compressor compartment 107 facing the evaporator compartment. This can place the evaporator 206 as far to the right as possible, increasing the size of the evaporator 206 that the first boss 40 and the second boss 50 can support.

[0144] Optionally, when the number of evaporators 206 is one, one first boss 40 and one second boss 50 are correspondingly provided for one evaporator 206.

[0145] Optionally, when the number of evaporators 206 is multiple, the multiple evaporators 206 include a first evaporator and a second evaporator. The first evaporator and the second evaporator are arranged at intervals in the front - rear direction on the drainage surface 103. The number of the first bosses 40 is the same as the number of the evaporators 206 and they correspond one by one. The number of the second bosses 50 is the same as the number of the first bosses 40 and they correspond one by one.

[0146] Optionally, when the multiple evaporators 206 include a first evaporator and a second evaporator, and the drainage surface 103 includes a first drainage surface 20, a front drainage surface 203, and a rear drainage surface 204, the first evaporator is located above the first drainage surface 20 and the front drainage surface 203, and the second evaporator is located above the first drainage surface 20 and the rear drainage surface 204. Among them, two first bosses 40 are provided on the first drainage surface 20, and the two first bosses 40 are arranged at intervals in the front - rear direction. The two first bosses 40 include a first front boss and a first rear boss. Two second bosses 50 are correspondingly provided for the two first bosses 40. The two second bosses 50 include a second front boss and a second rear boss. The second front boss is provided on the front drainage surface 203, and the second rear boss is provided on the rear drainage surface 204.

Among them, the first evaporator is located above the first front boss and the second front boss, and the second evaporator is located above the first rear boss and the second rear boss.

[0147] Optionally, the first front boss and the first rear boss can be the same or different.

[0148] In some other alternative embodiments, such as Figures 7 to 15 shown, the refrigeration device further includes a bump 30 protruding upward from the drainage surface 103. The bump 30 includes a bearing surface 301. The evaporator 206 is disposed above the bearing surface 301 and is in contact with the bearing surface 301. Among them, the bearing surface 301 is inclined in at least two directions, so that the defrosting water of the evaporator 206 flows toward at least two directions to the drainage surface 103 and then is discharged from the drainage port 104. The protrusion includes the bump 30.

[0149] In the embodiments of the present disclosure, a bump 30 is provided above the drainage surface 103, and the bearing surface 301 of the bump 30 can be inclined in at least two directions. In this way, the evaporator 206 is inclined in at least two directions at the same time, so that the defrosting water of the evaporator 206 can flow in multiple directions to improve the drainage path and drainage effect. Moreover, the bump 30 raises the height of the evaporator 206. In this way, when a part of the defrosting water of the evaporator 206 flows to the drainage surface 103, it has a certain initial velocity, which can improve the flow path of the defrosting water, then flow along the drainage surface 103, and then flow to the drainage port 104. In this way, there is no need to change the inclination angle of the drainage surface 103, nor to set a sunken structure, which can ensure the thickness of the foaming layer between the inner liner 10 and the cabinet shell, and can also ensure the adequacy of the drainage angle and the drainage efficiency.

[0150] In addition, the evaporator in the embodiments of the present disclosure is inclined and inclined in multiple directions, which can reduce the probability of water accumulation and improve the drainage thoroughness.

[0151] Optionally, in the left-right direction, the bearing surface 301 is inclined downward in the direction close to the drainage port 104, and in the front-back direction, the bearing surface 301 is inclined downward in the direction close to the drainage port 104.

[0152] In the embodiments of the present disclosure, the bearing surface 301 is inclined in the left-right direction and the front-back direction. The defrosting water in the evaporator compartment flows obliquely from front to back or from back to front to the drainage port 104, and the defrosting water in the evaporator compartment flows obliquely from left to right or from right to left to the drainage port 104, making the discharge process of the defrosting water smoother, improving the drainage effect of the evaporator compartment, and further ensuring the normal operation of the evaporator 206, thereby ensuring the refrigeration effect of the refrigeration device.

[0153] Optionally, when the evaporator 206 is located above the bearing surface 301, the first end and the second end of the evaporator 206 are oppositely arranged in the front-back direction, and in the front-back direction, the distance between the first end of the evaporator 206 and the drainage port 104 is less than the distance between the second end of the evaporator 206 and the drainage port 104. Among them, the bottom of the first end of the evaporator 206 is in contact with the drainage surface 103 to prevent air flow from flowing between the bottom of the first end of the evaporator 206 and the drainage surface 103.

[0154] In the embodiment of the present disclosure, when there is a gap between the bottom of the evaporator 206 and the drainage surface 103, it is possible to prevent the airflow in the evaporator compartment from flowing directly into the evaporator fan from below the evaporator 206 without passing through the evaporator 206 for dehumidification, which would cause direct frost under the action of low temperature, causing the evaporator fan to stop rotating.

The bump 30 further includes a first connecting wall 302 that connects between the drainage surface 103 and the second end of the bearing surface 301, so that the second end of the bearing surface 301 is higher than the first end of the bearing surface 301. The connecting wall includes the first connecting wall 302.

[0164] In the embodiments of the present disclosure, the first end of the bearing surface 301 abuts against the drainage surface 103, so that the first end of the evaporator 206 corresponding to the first end of the bearing surface 301 abuts against the drainage surface 103. The height of the second end of the bearing surface 301 is raised by the first connecting wall 302, so that the bearing surface 301 can be inclined downward in the front-rear direction.

[0165] Optionally, the third end and the fourth end of the bearing surface 301 are arranged in the left-right direction. In the left-right direction, the distance between the fourth end of the bearing surface 301 and the drainage port 104 is less than the distance between the third end of the bearing surface 301 and the drainage port 104.

The connecting wall includes the second connecting wall 303 and the third connecting wall 304.

[0166] In the embodiments of the present disclosure, the bump 30 can adjust the height of the bearing surface 301 through the second connecting wall 303 and the third connecting wall 304, so that the bearing surface 301 is inclined downward in the left-right direction towards the drainage port 104.

[0167] Optionally, the bump 30 is arranged on the first drainage surface 20.

[0168] In the embodiments of the present disclosure, the bump 30 is provided on the first drainage surface 20, which not only facilitates the setting of the bump 30, but also enables the water flowing to the first drainage surface 20 to flow more smoothly to the drain port 104.

[0169] Optionally, the bump 30 is provided at the end of the first drainage surface 20 away from the drain port 104.

[0170] In the embodiments of the present disclosure, the bump 30 is close to the end of the first drainage surface 20, so that the bump 30 can cooperate with the second drainage surface 201, so that both ends of the evaporator 206 in the left - right direction are in contact with the drainage surface 103, and it can ensure that the evaporator 206 can be tilted at a sufficient angle, improving the drainage effect and not easily accumulating water.

[0171] Optionally, the third connecting wall 304 and the connecting side wall 105 are in the same vertical plane.

[0172] In the embodiments of the present disclosure, the third connecting wall 304 and the connecting side wall 105 are in the same vertical plane, and the third connecting wall 304 is connected above the connecting side wall 105, so that the bump 30 is as close as possible to the end of the drainage surface 103, which can improve the guidance of the defrosting water of the evaporator 206 and prevent the defrosting water of the evaporator 206 from flowing to the first bottom wall 101.
