Description
Technical Field
[0001] This application relates to the field of refrigeration technology, for example, it relates to a refrigeration device. Background Art
[0002] Currently, for the freezers on the current market, basically the evaporator is placed on the upper step. In this solution, the drainage is from high to low, basically vertical, and is 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 freezer is disclosed in the related art. The freezer includes a cabinet and an inner liner. The inner liner is disposed inside the cabinet 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 provided 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, and there is 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. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0047] 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.
[0048] For the sake of convenience in description, the front, back, left, right, up, and down directions of this application are as Figure 1 and Figure 12 shown by the arrows.
[0049] Combined with Figures 1 to 15 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 outside 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.
[0050] 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.
[0051] Optionally, the refrigeration device is an air-cooled refrigeration device. The refrigeration device further includes an evaporation fan. The inner liner 10 defines an evaporator compartment and a compressor compartment 107. The compressor compartment 107 is located between the inner liner 10 and the box shell, the evaporator compartment is located inside the inner liner 10, the evaporator 206 is located in the evaporator compartment, the compressor is located in the compressor compartment 107, the evaporation fan is connected to the evaporator compartment, and 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 achieve air-cooled refrigeration of the storage space.
[0052] Optionally, the side wall of the inner container 10 is configured with an air duct and an air outlet. The air duct communicates with the storage space and the evaporator chamber. The evaporation fan can drive the air flow in the evaporator chamber into the air duct, and then flow into the storage space from the air outlet of the air duct. The evaporator chamber or the air duct is provided with a return air outlet. The air flow that releases cold in the storage space flows into the evaporator chamber through the return air outlet, thereby realizing the circulation of the air path.
[0053] Optionally, the inner container 10 includes a vertical side wall that is vertically arranged. The vertical side wall connects the bottom wall of the evaporator chamber and the top wall of the compressor chamber 107 of the refrigeration device. The vertical side wall separates the evaporator chamber and the compressor chamber 107. The refrigeration device further includes an evaporation fan that is vertically arranged on the bottom wall of the evaporator chamber. The evaporation fan includes a volute. Among them, the top wall of the evaporator chamber is flush with the top wall of the compressor chamber 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 chamber is equal to the height of the volute.
[0054] The top wall of the evaporator chamber is flush with the top wall of the compressor chamber 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 chamber and the top wall surface of the compressor chamber 107. Assuming that the evaporation fan is arranged on the drainage surface 103, 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 chamber. In this way, the evaporation fan can be vertically placed and will not protrude from the top wall of the evaporator chamber, ensuring that the top wall of the evaporator chamber is always flush with the top wall of the compressor chamber 107 and improving the aesthetic feeling. 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.
[0055] Optionally, the bottom wall of the evaporator chamber 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.
[0056] Optionally, as Figure 1 shown, the drainage port 104 is located at one end of the drainage surface 103 in the left-right direction. This facilitates the external connection of the drainage pipe to the drainage port 104 and also facilitates the setting of the drainage pipe.
[0057] Optionally, the compressor chamber 107 includes a drainage pipe and an evaporation dish. One end of the drainage pipe is connected to the drainage port 104, and the other end is connected to the evaporation dish to drain the defrosting water in the evaporator chamber into the evaporation dish.
[0058] Optionally, the compressor chamber 107 and the evaporator chamber are arranged side by side in the left-right direction. The drainage port is located at the end of the drainage surface 103 close to the compressor chamber 107. In this way, the defrosting water in the evaporator chamber flows into the drainage pipe in the compressor chamber 107 through the drainage port 104 and then flows into the evaporation dish for evaporation.
[0059] Optionally, as Figure 1 , Figure 7 shown, the bottom wall of the inner container 10 includes a first bottom wall 101 and a second bottom wall 102 connected to each other. The second bottom wall 102 is configured with a drainage surface 103 and a drainage port 104; the evaporator 206 is disposed above the second bottom wall 102; wherein, the second bottom wall 102 is higher than the first bottom wall 101.
[0060] 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 articles, and the second bottom wall 102 is used to place the evaporator 206. The defrosting water generated when the evaporator 206 defrosts can flow to the drainage surface 103 of the second bottom wall 102, and then flow along the drainage surface 103 to the drainage port 104 and flow out. Since the drainage surface 103 needs to be inclined towards the drainage port 104, therefore, the drainage 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 drainage 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 foaming layer, and there is no need to increase the thickness of the foaming layer to ensure the refrigeration effect. Moreover, without changing the thickness of the foaming layer, the inclination angle of the drainage surface 103 can be ensured to ensure the drainage rate and effect.
[0061] 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 drainage port 104 and extends in the vertical direction, so that the end of the second bottom wall 102 far from the drainage port 104 is higher than the first bottom wall 101.
[0062] In the embodiment 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, which can 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 drainage port 104, which is convenient for the drainage surface 103 of the second bottom wall 102 to be inclined towards the drainage port 104.
[0063] Optionally, the height difference range between the end of the second bottom wall 102 far from the drainage port 104 and the first bottom wall 101 is 20mm ≤ h ≤ 100mm.
[0064] In the embodiments of the present disclosure, when the height difference between one end of the second bottom wall 102 away from the drain outlet 104 and the first bottom wall 101 is less than 20 mm, the height difference is too small, which may lead to insufficient drainage surface 103 angle or may cause the 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 lead to 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 away from the drain outlet 104 and the first bottom wall 101 is greater than 100 mm, it will cause the height of the evaporator 206 to be too high, reducing the volume of the storage space.
[0065] Optionally, the height difference range between one end of the second bottom wall 102 away 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 away 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.
[0066] Exemplarily, the height difference between one end of the second bottom wall 102 away 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.
[0067] Optionally, the drain outlet 104 is located at the end of the second bottom wall 102 away from the first bottom wall 101.
[0068] 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.
[0069] Optionally, the lowest point of the drain outlet 104 is flush with or higher than the first bottom wall 101.
[0070] In the embodiments of the present disclosure, the lowest point of the drain outlet 104 is not lower than the first bottom wall 101, so that the second bottom wall 102 around the drain outlet 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 also be ensured.
[0071] Optionally, the drainage surface 103 includes a first drainage surface 20. The first drainage surface 20 is located on one side of the drain outlet 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 outlet 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.
[0072] In an embodiment of the present disclosure, the first drainage surface 20 is connected between the first bottom wall 101 and the drainage port 104. The first drainage port 104 is inclined from the first bottom wall 101 towards the drainage port 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 drainage port 104, so as to improve the drainage efficiency.
[0073] Optionally, the included angle a between the first drainage surface 20 and the horizontal direction is greater than or equal to 3°.
[0074] In an embodiment 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, which will lead to insufficient drainage angle and insufficient drainage.
[0075] 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 is inclined downward in the front-rear direction along the direction close to the drainage port 104.
[0076] In an embodiment 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 is also inclined downward in the front-rear direction along the direction close to the drainage port 104. In this way, for the water flowing along the second drainage surface 201 in the front-rear direction, 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 drainage port 104 along the position of the second drainage surface 201 close to the drainage port 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 drainage port 104 and flow out.
[0077] In addition, in this way, the drainage surface 103 is designed into multiple ones, and the position of the drainage port 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 is inclined downward in the direction from back to front, from front to back, from left to right, or from right to left, when the inclination angle and inclination direction 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 insulation layer and the heat insulation effect of the refrigeration equipment is better.
[0078] Optionally, the included angle b between the second drainage surface 201 and the horizontal direction is less than or equal to 10°.
[0079] In an embodiment of the present disclosure, when the included angle b between the second drainage surface 201 and the horizontal direction is greater than 10°, the inclination angle of the second drainage surface 201 is too large, which is not conducive to 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.
[0080] 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 - rear 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.
[0081] 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 wall of the inner container 10, the front drainage surface 203 slopes downward along the front - to - rear direction, and one end of the front drainage surface 203 facing 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 wall of the inner container 10, the rear drainage surface 204 slopes downward along the rear - to - front direction, and one end of the rear drainage surface 204 facing away from the rear wall forms a second hypotenuse. Among them, the first drainage surface 20 is connected between the first hypotenuse and the second hypotenuse. 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 provided at the intersection of the first hypotenuse, the second hypotenuse and the first drainage surface 20.
[0082] In an embodiment of the present disclosure, the rear drainage surface 204 slopes downward along the rear - to - front direction, and the front drainage surface 203 slopes downward along the front - to - rear direction. Therefore, the first hypotenuse and the second hypotenuse are the lowest sides of the front drainage surface 203 and the rear drainage surface 204, and 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 opening 104 at the lowest point can make the discharge process of the defrosting water in the evaporator compartment smoother, improve the drainage effect of the evaporator compartment, 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.
[0083] Optionally, the bottom wall of the evaporator compartment 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 compartment 107.
[0084] Optionally, in the left - right direction, the second drainage surface 201 slopes downward toward the direction close to the compressor compartment 107.
[0085] In the disclosed embodiment, the second drainage surface 201 is tilted downward in the left-right direction toward the direction close to the compressor chamber 107, so that one end of the second drainage surface 201 is close to the drain outlet 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 along the left-right direction toward the drain outlet 104 close to the compressor chamber 107.
[0086] Optionally, when the second drainage surface 201 includes a front drainage surface 203 and a rear drainage surface 204, the front drainage surface 203 and the rear drainage surface 204 are both inclined downward in the left and right directions toward the direction close to the compressor cabin 107, so that the lowest point of the first bevel or the second bevel is just close to one end of the compressor cabin 107, and the drain port 104 is arranged at the lowest point of the lowest edge of the bottom wall of the evaporator cabin, which can make the discharge process of the defrost water in the evaporator cabin smoother, improve the drainage effect of the evaporator cabin, and then ensure the normal operation of the evaporator 206, thereby ensuring the refrigeration effect of the refrigeration equipment.
[0087] Optionally, the first drainage surface 20 is triangular, the base of the triangle is located on the side of the evaporator compartment away from the compressor compartment 107, the vertex is located on the side of the evaporator compartment close to the compressor compartment 107, and the first drainage surface 20 is inclined along the base of the triangle toward the vertex. The drainage port 104 is provided at the vertex of the triangle. In this way, the first drainage surface 20 in a triangular shape is inclined downward in the left-right direction toward the compressor compartment 107.
[0088] Optionally, the evaporator 206 is placed horizontally in the evaporator cabin, which can reduce the height of the evaporator cabin and increase the volume of the storage space.
[0089] In some optional embodiments, such as Figures 1 to 6 As 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 .
[0090] In this way, the evaporator 206 can be stably supported without the need for an additional bracket, and the evaporator 206 can be placed horizontally, minimizing the obstruction of the evaporator 206 to the flow path of the defrost water, and the drainage of the evaporator compartment is smoother.
[0091] Optionally, the drain surface 103 further includes a fourth drain surface 205. The fourth drain surface 205 is disposed between the first drain surface 20 and the second drain surface 201. The first end of the fourth drain surface 205 is connected to the second drain surface 201, and the second end of the fourth drain surface 205 is connected to the first drain surface 20. The first end of the fourth drain surface 205 is higher than the second end of the fourth drain surface 205, and along the direction from the first end to the second end of the fourth drain surface 205, the fourth drain surface slopes downward. The fourth drain surface 205 and the first drain surface 20 jointly define a drain portion, and the drain opening 104 is located at the lowest point of the drain portion.
[0092] The first end of the fourth drain surface 205 is higher than the second end of the fourth drain surface 205, that is, the fourth drain surface 205 extends in the up-and-down direction. The second drain surface 201 is higher than the first drain surface 20. In this way, the defrost water at the lowest point of the second drain surface 201 can smoothly flow into the drain portion through the fourth drain surface 205, reducing water accumulation. The defrost water in the evaporator compartment first flows into the drain portion and then flows out of the evaporator compartment through the drain opening 104, avoiding the problem of water accumulation and icing on the side of the second drain surface 201 close to the compressor compartment 107.
[0093] Optionally, along the front-rear direction, the inclination angle of the fourth drain surface 205 is greater than the inclination angle of the second drain surface. In this way, the water flow on the second drain surface can flow to the fourth drain surface 205 and then accelerate to flow to the drain portion, improving the drainage speed.
[0094] Optionally, the number of the fourth drain surfaces 205 is two. The two fourth drain surfaces 205 are respectively disposed on both sides of the first drain surface 20 in the front-rear direction. The two fourth drain surfaces 205 and the first drain surface 20 enclose the drain portion, and the drain opening 104 is located at the lowest point of the drain portion.
[0095] Optionally, the evaporator 206 is placed in contact with the second drain surface 201 and is located above the drain portion.
[0096] In this way, the evaporator 206 has a high degree of fit with the second drain 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 disposed above the drain portion. In this way, the water vapor attached to the surface of the part of the evaporator 206 located above the drain portion can directly drip into the drain portion and be discharged from the evaporator compartment through the drain opening 104, improving the drainage efficiency.
[0097] In some alternative embodiments, the number of the drain surfaces 103 is one, and the drain opening 104 is located at the corner of the drain surface 103.
[0098] The number of the drainage surfaces 103 is one. The bottom wall of the evaporator compartment, i.e., the second bottom wall 102, is composed of only one drainage surface 103, which has a simple structure, reduces the process difficulty, and saves costs. Assuming that the single drainage surface 103 slopes downward in the direction from the rear to the front and slopes to the right in the direction from the left to the right, then the lowest point of the single drainage surface 103 is at the end corner in its right front. Setting the drain port 104 here can meet the requirement that the drain port 104 is lower than any point on the single drainage surface 103.
[0099] Optionally, the refrigeration device further includes a protrusion, which is provided on the drainage surface and protrudes upward from the drainage surface, and the protrusion supports below the evaporator to make the evaporator inclined or horizontally arranged.
[0100] In the embodiment of the present disclosure, a protrusion is provided 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 appearance.
[0101] In some other alternative embodiments, as Figures 7 to 15 shown, the refrigeration device further includes a convex block 30, the convex block 30 protrudes upward from the drainage surface 103, and the convex block 30 includes a bearing surface 301; the evaporator 206 is arranged above the bearing surface 301 and is in contact with the bearing surface 301; wherein, and the bearing surface 301 slopes in at least two directions, so that the defrost water of the evaporator 206 flows in at least two directions to the drainage surface 103 and then is discharged from the drain port 104. The protrusion includes the convex block 30.
[0102] In the embodiment of the present disclosure, a convex block 30 is provided above the drainage surface 103, and the bearing surface 301 of the convex block 30 can slope in at least two directions. In this way, the evaporator 206 slopes in at least two directions at the same time, so that the defrost water of the evaporator 206 can flow in multiple directions to improve the drainage path and drainage effect. Moreover, the convex block 30 raises the height of the evaporator 206. When a part of the defrost 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 defrost water, then flows along the drainage surface 103 and then flows to the drain port 104. In this way, it is not necessary to change the inclination angle of the drainage surface 103, nor to set a sinking 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.
[0103] In addition, the evaporator in the embodiment of the present disclosure is inclined and inclined in multiple directions, which can reduce the probability of water accumulation and improve the drainage thoroughness.
[0104] Optionally, there is one protrusion.

[0109] It can be understood that the bearing surface 301 is inclined along other directions, such as the diagonal direction of the inner container, etc. In actual applications, the inclination angle of the bearing surface can be set according to usage requirements.
[0110] Optionally, when the evaporator 206 is located above the supporting surface 301, the first end of the evaporator 206 and the second end of the evaporator 206 are arranged opposite to each other in the front-to-back direction, and in the front-to-back direction, the distance between the first end of the evaporator 206 and the drain outlet 104 is smaller than the distance between the second end of the evaporator 206 and the drain outlet 104; wherein, the bottom of the first end of the evaporator 206 abuts against the drain surface 103 to prevent airflow from flowing between the bottom of the first end of the evaporator 206 and the drain surface 103.
[0111] 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 bottom of the first end of the evaporator 206 in the embodiment of the present disclosure can abut against the drainage surface 103, and can block the gap between the bottom of the first end of the evaporator 206 and the drainage surface, preventing the airflow from flowing directly into the evaporator fan without passing through the evaporator 206, which can avoid air leakage and reduce the risk of icing of the evaporator fan.
