Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more particularly to a freezer. Background Technology

[0002] The freezer door is located at the top of the cabinet. After opening the door, the user takes out the items below from the opening at the top. Air-cooled freezers also include a compressor, evaporator, and fan. These components are generally located at the bottom of the freezer. The compressor, evaporator, and fan require a certain amount of space, and if the layout of these components is not reasonable, it will result in low space utilization when users place items inside.

[0003] When the evaporator and fan need to be installed independently inside the freezer, a sealing problem arises, requiring the use of sealing materials such as sealing cotton. However, during installation, relative displacement occurs between the modules, which can scratch the sealing cotton, causing it to be damaged and leading to seal failure, thus affecting the cooling effect.

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0038] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0039] One embodiment of the present invention provides a freezer that effectively protects the sealing material and has better sealing performance. The freezer has excellent cooling and defrosting effects and provides a better user experience.

[0040] The freezer 100 includes a cabinet forming the outer shell, an inner liner 30 disposed inside the cabinet, a refrigeration compartment enclosed by the inner liner 30, a door that can close or open the refrigeration compartment, and a refrigeration system. The refrigeration system includes a compressor, a condenser, a throttling device, a finned evaporator 12, and pipes connecting the various components. Refrigerant flows through the pipes. Through the circulation of the refrigerant, the evaporator is cooled, and the entire refrigeration compartment is further cooled. A compressor compartment is disposed inside the stepped portion 34. The compressor is disposed inside the compressor compartment.

[0041] To clearly express the positions and directions described in this embodiment, the direction in which the door opens is defined as "up" and the opposite direction as "down." That is, the door is located above the cabinet. The freezer 100 is generally a cuboid, with its length ends on the left and right, and its width ends on the front and rear. The compressor compartment is defined as being located on the right side of the inner liner 30, and the other side is the left side. Clockwise rotation on the right side is "front," and counterclockwise rotation on the right side is "rear." Alternatively, when the freezer 100 is placed on a horizontal surface, the direction of gravity can also be defined as "down" and the opposite direction as "up." The user stands on one side of the freezer 100 along its length, facing the freezer 100, with the compressor compartment located on the right side of the freezer 100. In this case, the user is standing in front of the freezer 100.

[0042] like Figure 1-4 As shown, one embodiment of the present invention discloses a freezer 100, including an inner liner 30, an evaporator module 10, a fan module 20, a first guide section and a second guide section. The inner liner 30 includes a rear side wall 31, a front side wall 32, a bottom plate 33, and a stepped portion 34 connecting the rear side wall 31, the front side wall 32 and the bottom plate 33. The front side wall 32 and the rear side wall 31 are two side walls in the length direction, respectively. The compressor compartment in the stepped portion 34 is used to accommodate the compressor, and the top of the stepped portion 34 is higher than the bottom plate 33.

[0043] like Figure 7 As shown, the evaporator module 10 includes a first seal 15 facing the rear sidewall 31 and a second seal 16 facing the step portion 34; the fan module 20 includes a third seal 25 facing the front sidewall 32 and a fourth seal 26 facing the step portion 34. The first seal 15 is used to ensure the seal between the evaporator module 10 and the rear sidewall 31, the second seal 16 is used to ensure the seal between the evaporator module 10 and the sidewall of the step portion 34, the third seal 25 is used to ensure the seal between the fan module 20 and the front sidewall 32, and the fourth seal 26 is used to ensure the seal between the fan module 20 and the step portion 34.

[0044] The first guide portion guides the evaporator module 10 to move along a first direction to a first assembly position. This first direction has components both toward the rear sidewall 31 and toward the step portion 34. At the first assembly position, the first seal 15 abuts against the rear sidewall 31, and the second seal 16 abuts against the step portion 34. The first direction is as follows: Figure 3 or Figure 6 As shown, in the first direction, the evaporator module 10 moves simultaneously to the rear sidewall 31 and the step portion 34, that is, to the right rear. Before the evaporator module 10 moves to the first assembly position, the first seal 15 will not abut against the rear sidewall 31, and the second seal 16 will not abut against the step portion 34, so neither the first seal 15 nor the second seal 16 will be scratched.

[0045] In addition, the evaporator module 10 includes a bottom support 11, a finned evaporator 12 and an evaporator cover 13, and the fan module 20 includes a fan support 21, an evaporator fan 22 and a fan cover 23. The fan support 21 is located above the bottom support 11 and is connected to the bottom support 11. The distance between the rear side wall 31 and the front side wall 32 is greater than the length of the bottom support 11.

[0046] In other words, when the evaporator module 10 moves, because its length is less than the distance between the rear sidewall 31 and the front sidewall 32, it can move in the front-rear direction and will not be simultaneously blocked between the front sidewall 32 and the rear sidewall 31. When the evaporator module 10 starts moving, the parameters... Figure 3 As shown, there can be a distance d1 between the evaporator module 10 and the right-side step 34, and a distance d2 between the evaporator module 10 and the rear side wall 31. Then, the evaporator module 10 moves to the right rear until d1 and d2 simultaneously decrease to 0. After the evaporator module 10 moves into position, the evaporator cover 13 abuts against the rear side wall 31 and the step 34.

[0047] The second guide section guides the fan module 20 to move along a second direction to the second assembly position. This second direction includes components facing the front sidewall 32, facing the step portion 34, and downwards. At the second assembly position, the third seal 25 abuts against the front sidewall 32, and the fourth seal 26 abuts against the step portion 34. The second direction is as follows: Figure 4 or Figure 6As shown, in the second direction, the fan module 20 moves simultaneously to the front sidewall 32 and the step portion 34, that is, to the right, forward, and downward. Before the evaporator module 10 moves to the second assembly position, the third seal 25 will not abut against the front sidewall 32, and the fourth seal 26 will not abut against the step portion 34, so neither the third seal 25 nor the fourth seal 26 will be scratched. After the fan module 20 moves into position, the fan cover 23 abuts against the front sidewall 32 and the step portion 34.

[0048] In addition, the distance between the rear side wall 31 and the front side wall 32 is equal to the sum of the lengths of the evaporator cover plate 13 and the fan cover plate 23. Therefore, after the fan module 20 moves into place, the fan cover plate 23 and the evaporator cover plate 13 are exactly equal in width to the front side wall 32 and the rear side wall 31.

[0049] Furthermore, the step portion 34 includes a step sidewall 341 and a step top wall 342, with the second seal 16 and the fourth seal 26 both abutting against the step sidewall 341; the evaporator cover plate 13 includes mutually perpendicular evaporator sidewalls 131 and evaporator top walls 132, and the fan cover plate 23 includes mutually perpendicular fan sidewalls 231 and fan top walls 232. The evaporator top wall 132 and fan top wall 232 are both flush with the step top wall 342, forming a unified plane that makes the spatial shape regular. If the freezer 100 is placed on a horizontal surface, the plane formed by the evaporator top wall 132, fan top wall 232, and step top wall 342 is also parallel to the horizontal plane, while the evaporator sidewall 131 and fan sidewall 231 are perpendicular to the horizontal plane. Figure 1 , 2 As shown in Figures 7 and 8, this allows users to easily place ingredients.

[0050] The first seal 15 includes a first sealing edge 151 adjacent to the evaporator sidewall 131, a second sealing edge 152 adjacent to the evaporator top wall 132, and a third sealing edge 153 adjacent to the step sidewall 341; the third seal 25 includes a fourth sealing edge 251 adjacent to the fan sidewall 231, a fifth sealing edge 252 adjacent to the fan top wall 232, and a sixth sealing edge 253 adjacent to the step sidewall 341. Figure 7 As shown, seals are used to protect the evaporator module 10 and the fan module 20 in each direction.

[0051] In addition, the freezer 100 also includes a fifth seal 40, such as Figure 8 As shown, the fifth seal 40 extends and is disposed at the junction between the evaporator module 10 and the fan module 20, ensuring a seal at the joint.

[0052] Furthermore, the first guide portion includes a first guide member disposed on the base plate 33 and a second guide member disposed on the evaporator module 10 facing the base plate 33. One of the first guide member and the second guide member is configured as a guide protrusion 35 and the other is configured as a guide groove 111. The guide groove 111 extends along the first direction, and the guide protrusion 35 is inserted into the guide groove 111. That is, both the guide protrusion 24 and the guide groove 14 extend to the right rear.

[0053] Specifically, such as Figure 5 As shown, the base plate 33 has a through hole 331. The first guide is a guide protrusion 35, which includes a head 351, a fixing part and a groove. The fixing part is fixedly connected to the through hole 331. The second guide is a guide groove 111, which is inserted into the groove between the head 351 and the fixing part.

[0054] The cross-sectional dimension of the guide groove 111 increases along the first direction, and the cross-section of one end of the guide groove 111 can cover the cross-section of the head 351, while the cross-section of the head 351 can cover the cross-section of the other end of the guide groove 111.

[0055] When the evaporator module 10 begins to move, the head 351 is located at the end of the guide groove 111 with a larger cross-section. Then, the evaporator module 10 moves to the right rearward in a first direction until it reaches the end of the guide groove 111 with a smaller cross-section, i.e., it moves to... Figure 5 The position of the evaporator module 10 forms the guide and fixation.

[0056] Furthermore, the second guide section includes a third guide member disposed on the evaporator module 10 and a fourth guide member disposed on the fan module 20 facing the evaporator module 10. One of the third guide member and the fourth guide member is configured as a guide protrusion 24 and the other is configured as a guide groove 14. The guide groove 14 extends along the second direction, and the guide protrusion 24 is inserted into the guide groove 14. That is, both the guide protrusion 24 and the guide groove 14 extend to the right front.

[0057] Specifically, such as Figure 5 , 6 As shown in Figures 8, 9, and 10, the third guide is configured as a guide groove 14, and the fourth guide is configured as a guide protrusion 24. The guide groove 14 includes a first inclined wall 141 and a second inclined wall 142 connected to each other. The first inclined wall 141 extends downward and is inclined towards the step portion 34, and the second inclined wall 142 extends downward and is inclined towards the front side wall 32. The guide protrusion 24 includes a third inclined wall 241 and a fourth inclined wall 242. The third inclined wall 241 matches the first inclined wall 141, and the fourth inclined wall 242 matches the second inclined wall 142.

[0058] The fan module 20 has two functions: first, to guide and fix its own movement position; and second, to enable the evaporator module 10 to move to the first position to the right and rear. There is a gap between the front of the evaporator module 10 and the front side wall 32, which the fan module 20 needs to fill. In order to collect the water during defrosting, the evaporator module 10 extends below the fan module 20. The fan module 20 has limited space, so a guide groove 14 is provided on the evaporator module 10 and a guide protrusion 24 is provided on the fan module 20 to guide its movement.

[0059] The third inclined wall 241 and the first inclined wall 141 tilt downward to the right, while the second inclined wall 142 and the fourth inclined wall 242 tilt downward to the front. Together, they form the direction of movement of the fan module 20 downward, forward, and rightward, ultimately filling the gap between the evaporator module 10 and the front side wall 32. This forms a single plane by connecting the fan top wall 232, the evaporator top wall 132, and the stepped top wall 342. The fan side wall 231 and the evaporator side wall 131 are flush and form a single plane.

[0060] The freezer 100 also includes a first fixing component and a second fixing component. When the evaporator module 10 is in the first assembly position, the first fixing component fixes the evaporator module 10 and the base plate 33. When the fan module 20 is in the second assembly position, the second fixing component fixes the evaporator module 10 and the fan module 20. After the evaporator module 10 and the fan module 20 have moved into position, they are firmly fixed in place by the first fixing component and the second fixing component.

[0061] Compared with the prior art, this embodiment has the following beneficial effects: the freezer 100 sets the evaporator and the fan as two independent modules for installation. During the installation process, the evaporator module 10 moves to the first assembly position in the first direction, and the fan module 20 moves to the second assembly position in the second direction. The assembly method formed by this structure avoids the wear and failure of the first seal 15 to the fourth seal 26, and ensures the sealing effect.

[0062] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0063] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
