Description

refrigerator

Technical Field

The invention belongs to the technical field of refrigerators, and specifically provides a refrigerator.

Background technique

The overall shape, number of internal compartments and volume of internal compartments of the same series of refrigerators are the same. Refrigerators of different models often differ only in color and shell material. Due to the different layouts and decoration styles of different families and the different preferences of different users, the existing refrigerators cannot meet the needs of the majority of users. And manufacturers cannot provide users with customized refrigerators according to their needs. The reason is that the existing refrigerators generally integrate the refrigeration system into the refrigerator body, so manufacturers need to redesign the structure and layout of the refrigerator according to the needs of users. For this purpose, more new molds need to be opened, resulting in high production costs and long production cycles for refrigerators.

In order to overcome the above problems, the prior art proposes a modular refrigerator solution. Specifically, the refrigerator is designed into two independent modules: a cabinet module and a refrigeration module. The refrigeration module can adapt to a variety of different cabinet modules, so that the refrigeration module and the corresponding cabinet module can be assembled together according to the user's customized needs.

The existing cabinet module generally needs to be lifted by a lifting device and transferred to the top of the refrigeration module, and then fixed to the refrigeration module by bolts. This situation not only limits the assembly efficiency of the refrigerator, but also makes it difficult for operators to assemble.

Summary of the invention

An object of the present invention is to solve the problem that the existing cabinet module needs to be assembled with the refrigeration module with the aid of a lifting device, resulting in low assembly efficiency with the refrigeration module.

A further object of the present invention is to enable an operator to sense whether a box module has been moved into place during assembly and disassembly.

Another further object of the present invention is to optimize the sealing performance between box modules.

To achieve the above-mentioned object, the present invention provides a refrigerator, comprising a box module and a refrigeration module, wherein the box module defines a storage compartment and a receiving cavity located at the bottom of the box module, the receiving cavity has a front opening and a bottom opening, and at least one roller is respectively arranged on the left and right walls of the receiving cavity; the refrigeration module comprises a shell and a refrigeration system arranged in the shell, and the left and right sides of the shell are respectively provided with lower slide rails extending forward and backward; the roller is in rolling contact with the lower slide rail so that the box module can be moved from The rear side of the refrigeration module slides forward to a position matching with the refrigeration module, thereby enabling the refrigeration module to be embedded in the accommodating cavity.

Optionally, a roller is respectively provided on the left and right walls of the accommodating cavity, and the roller is located at the rear of the accommodating cavity; the top surface of the lower sliding rail includes a first lower inclined surface and a lower plane located in front of the first lower inclined surface, and the first lower inclined surface is inclined forward and upward from the rear end of the lower sliding rail.

Optionally, the top surface of the lower sliding rail further includes a second lower inclined surface located between the first lower inclined surface and the lower plane, and the second lower inclined surface is inclined downward from back to front.

Optionally, a stop block is provided on the box module and is located in front of the roller. The shell also includes a baffle plate provided above the lower slide rail. The stop block and the baffle plate are configured such that the stop block can abut against the baffle plate when the box module forms a first angle with the horizontal plane and the roller moves forward, and the stop block will not abut against the baffle plate when the box module forms a second angle with the horizontal plane and the roller moves forward; the first angle is greater than the second angle.

Optionally, when the refrigerator is assembled, the stopper abuts against the lower plane; and/or, the stopper forms a chamfer between its front side surface and its bottom surface.

Optionally, the baffle includes a horizontal portion parallel to the lower plane and an inclined portion parallel to the second lower inclined surface.

Optionally, an upper slide rail is provided on the cabinet module, and a slot for accommodating the roller is provided at the front of the lower slide rail; when the refrigerator is assembled, the roller is embedded in the slot, and the upper slide rail abuts against the lower slide rail.

Optionally, the bottom surface of the upper slide rail includes a first upper plane adapted to the lower plane and an upper inclined plane adapted to the second lower inclined plane, and when the refrigerator is assembled, the upper plane abuts against the lower plane, and the upper inclined plane extends backward to the rear side of the second lower inclined plane.

Optionally, the upper inclined surface abuts against the second lower inclined surface; and/or, the bottom surface of the upper slide rail further includes a second upper plane located at the rear side of the upper inclined surface.

Optionally, the refrigerator further includes a compressible and deformable sealing gasket arranged between the top wall of the accommodating cavity and the top surface of the shell, wherein the sealing gasket is squeezed by the cabinet module and the shell when the refrigerator is assembled; the vertical distance between the lowest position of the roller and the first upper plane is greater than the thickness of the sealing gasket; and/or the vertical distance between the lowest position of the roller and the first upper plane is greater than the vertical distance between the lower plane and the top of the first lower inclined surface.

Based on the above description, those skilled in the art can understand that, in the above technical solution of the present invention, by providing a receiving cavity at the bottom of the box module, and providing at least one on the left and right walls of the receiving cavity, Rollers; lower rails extending forward and backward are respectively arranged on the left and right sides of the housing of the refrigeration module, so that the cabinet module can slide forward from the rear side of the refrigeration module to a position matching with the refrigeration module by means of rolling contact between the rollers and the lower rails, so that the refrigeration module is embedded in the accommodating cavity, thereby realizing the assembly of the cabinet module and the refrigeration module. Therefore, the refrigerator of the present invention does not need to use lifting equipment to move the cabinet module to the refrigeration module, which not only improves the assembly efficiency of the refrigerator, but also reduces the assembly difficulty of the operator.

Furthermore, by making the top surface of the lower slide rail include a first lower slope and a lower plane located in front of the first lower slope, and making the first lower slope tilt forward and upward from the rear end of the lower slide rail, the roller on the refrigerator module can slide from a plane lower than the lower plane to the lower plane with the help of the first lower slope, and then roll on the lower plane.

Furthermore, by providing a stopper located at the front side of the roller on the cabinet module, and providing a baffle plate located above the lower slide rail on the housing, and enabling the stopper to abut against the baffle plate when the cabinet module is at a first angle to the horizontal plane and the roller moves forward, the operator can sense that the cabinet module needs to be lifted to a certain angle. By ensuring that the stopper does not abut against the baffle plate when the cabinet module is at a second angle to the horizontal plane and the roller moves forward to the top of the first lower slope, it is ensured that the cabinet module can be moved to a position that matches the refrigeration module.

Furthermore, by forming a chamfer between the front side and the bottom of the stopper, when the cabinet module is removed from the refrigeration module, the rear part of the cabinet module is moved upward so that the chamfer can contact the lower slide rail and serve as a fulcrum to slide the roller out of the slot. At the same time, the contact friction between the chamfer and the lower slide rail is smaller than that between the right angle and the lower slide rail, making it easier for the cabinet module to slide on the lower slide rail.

Furthermore, by making the bottom surface of the upper slide rail further include a second upper plane located at the rear side of the upper inclined surface, when the cabinet module is removed from the refrigeration module, the rear part of the cabinet module can be pressed downward, so that the concave structure formed between the second upper plane and the upper inclined surface clamps the protrusion between the first lower inclined surface and the second lower inclined surface and uses this as a fulcrum. Then, the operator can pull the cabinet module backward to make the roller slide out of the clamping slot.

Furthermore, during the process of the roller being embedded in the slot, the sealing gasket is compressed and the top end of the sealing gasket is displaced backward relative to the bottom end, so that the cross-section of the sealing gasket perpendicular to the left and right directions is a parallelogram. Compared with the irregular deformation produced when the sealing gasket is compressed, the sealing effect is better.

Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention.

Further, a sink groove is provided on the inner side of the second door body, and the sink groove has a portion aligned with and connected to the second storage compartment 1012 and a portion aligned with and connected to the front return air vent 21021 of the refrigeration module 200, so that the air in the second storage compartment 1012 flows to the refrigeration module 200 through the sink groove.

In addition, in some other embodiments of the present invention, those skilled in the art may also, as needed, set a channel on the second door body, and align and connect one end of the channel with the second storage compartment 1012, and align and connect the other end of the channel with the front return air outlet 21021 of the refrigeration module 200.

Continuing to refer to FIG. 1 to FIG. 3, in some embodiments of the present invention, the box module 100 includes a first inner liner 110, a second inner liner 120, an air supply duct 130 and an air return duct 140 disposed in its housing (not marked in the figure). A first storage compartment 1011 is formed in the first inner liner 110, and a second storage compartment 1012 is formed in the second inner liner 120. In other words, the first storage compartment 1011 is defined by the first inner liner 110, and the second storage compartment 1012 is defined by the second inner liner 120. An air supply channel 1301 (as shown in FIG. 13) is defined in the air supply duct 130, and the air supply channel 1301 is communicated with the first storage compartment 1011 and the second storage compartment 1012, respectively, so that the box module 100 receives cold air from the refrigeration module 200 through the air supply channel 1301, and delivers the cold air to the first storage compartment 1011 and the second storage compartment 1012. A first return air channel is formed in the return air duct 140 , and a top end of the first return air channel is connected to the first air outlet 10111 , so that the cabinet module 100 transports the air in the first storage compartment 1011 to the refrigeration module 200 through the first return air channel.

As shown in FIG. 2 and FIG. 3 , in some embodiments of the present invention, the cabinet module 100 further includes a cover shell 150 disposed at the bottom thereof, and a receiving chamber 102 is defined in the cover shell 150, and the receiving chamber 102 is used to receive the refrigeration module 200. The receiving chamber 102 has a front opening 1021 and a bottom opening 1022, and the front opening 1021 and the bottom opening 1022 are used to move the cabinet module 100 from the rear side of the refrigeration module 200 to the top of the refrigeration module 200, so as to fix the cabinet module 100 and the refrigeration module 200 together after the cabinet module 100 moves to a position matching the refrigeration module 200.

As shown in FIG. 3 , an inner slope 1023 is formed between the rear side wall and the top wall of the accommodating cavity 102 , and the inner slope 1023 matches the outer slope 2112 (as shown in FIG. 4 ) on the refrigeration module 200 .

2 and 3, a roller 160 is respectively disposed on the left and right walls of the accommodating chamber 102, and the roller 160 is located at the rear of the accommodating chamber 102. In the process of assembling the cabinet module 100 and the refrigeration module 200 together, the roller 160 can support the weight of the cabinet module 100, and thus move the cabinet module 100 in the front-to-back direction to a position matching the refrigeration module 200.

In addition, in other embodiments of the present invention, those skilled in the art may also respectively set other numbers of rollers 160 on the left and right walls of the accommodating cavity 102 as needed, such as two, three, five, etc., respectively.

2 and 3 , an upper slide rail 170 and a stopper 180 are respectively provided on the left and right walls of the accommodating chamber 102. The upper slide rail 170 extends in the front-to-back direction of the box module 100. Optionally, the upper slide rail 170 is located at the rear side of the roller 160, and the stopper 180 is located at the front side of the roller 160.

Furthermore, the bottom surface of the upper slide rail 170 includes a first upper plane 171, a second upper plane 172 and an upper inclined plane 173, so that the upper slide rail 170 matches the lower slide rail 212 on the refrigeration module 200 (as shown in Figures 4 and 5) through the first upper plane 171, the second upper plane 172 and the upper inclined plane 173.

As shown in FIG3 , a front threaded hole 181 is provided on the stopper 180. A chamfer is formed between the front side surface and the bottom surface of the stopper 180, so that the stopper 180 contacts the lower lower rail 212 on the refrigeration module 200 through the chamfer. It can be understood by those skilled in the art that the contact between the chamfer and the lower lower rail 212 has a smaller friction force than the contact between the right angle and the lower lower rail 212, making it easier for the cabinet module 100 to slide on the lower lower rail 212.

As shown in Fig. 2 and Fig. 3, a plurality of rear fixing holes 151 are provided on the rear side wall of the accommodating chamber 102, and a plurality of bottom threaded holes 152 are provided at the bottom end of the cabinet module 100 (specifically, the bottom end of the cover 150).

Further, an outer inclined surface 2112 is formed between the rear side wall and the top wall of the housing 210, and the air supply port 2101 is formed on the outer inclined surface 2112.

As shown in Figure 2, when the refrigerator is assembled, the outer slope 2112 abuts against the inner slope 1023 on the cabinet module 100, and the air supply port 2101 is connected to the air supply duct 130 on the cabinet module 100, so that the refrigeration module 200 supplies air to the air supply duct 130 through the air supply port 2101, and the air supply duct 130 then transports the received cold air to the storage compartment 101.

As shown in FIG. 2 and FIG. 3 , when the refrigerator is assembled, the front return air vent 21021 and the second storage compartment 1012 are both located at the front side of the refrigerator, and the two are connected through a sink or channel formed on the second door body (as described above), so that the refrigeration module 200 receives air from the second storage compartment 1012 through the front return air vent 21021. The side return air vent 21022 is connected to the return air duct 140 on the cabinet module 100, so that the refrigeration module 200 receives air from the first storage compartment 1011 through the side return air vent 21022.

As shown in FIGS. 4 to 6, the left and right sides of the housing 210 are respectively provided with lower rails 212 extending forward and backward, and the top surface of the lower rail 212 includes a first lower inclined surface 2121, a second lower inclined surface 2122 and a lower plane 2123 distributed from back to front, and the first lower inclined surface 2121 is used to guide the roller 160 on the box module 100 to slide to the lower surface. On the rail 212, the second lower slope 2122 is used to prevent the roller 160 from sliding off the lower rail 212, and the lower plane 2123 is used to carry the roller 160 to move forward. Specifically, the first lower slope 2121 tilts forward and upward from the rear end of the lower rail 212, and the second lower slope 2122 tilts forward and downward from the rear end of the lower rail 212.

As shown in Fig. 4 and Fig. 5, a slot 2124 for accommodating the roller 160 is provided at the front of the lower slide rail 212. When the cabinet module 100 and the refrigeration module 200 are assembled, the roller 160 is embedded in the slot 2124.

As shown in FIGS. 4 to 6 , the housing 210 is provided with a fixing plate 213 located at the bottom side of the lower sliding rail 212, at least a portion of the fixing plate 213 in the left-right direction is located outside the lower sliding rail 212, and a plurality of bottom fixing holes 2131 are provided on the portion of the fixing plate 213 located outside the lower sliding rail 212. The bottom fixing holes 2131 correspond to the bottom threaded holes 152 on the box module 100. Further, a plurality of front threaded holes 181 are provided on the front side of the housing 210, and the front threaded holes 181 correspond to the front fixing holes 2141 on the box module 100. Further, a plurality of rear threaded holes 2142 are provided on the rear side of the housing 210, and the rear threaded holes 2142 correspond to the rear fixing holes 151 on the box module 100.

As shown in FIG. 7 , in some embodiments of the present invention, the refrigerator further includes at least one bolt 300 . Specifically, the at least one bolt 300 includes a front bolt 310 , a rear bolt 320 , and a bottom bolt 330 .

Although not shown in the figure, when the cabinet module 100 and the refrigeration module 200 are assembled, the front fixing hole 2141 on the cabinet module 100 is located on the outside (rear side) of the front threaded hole 181 on the refrigeration module 200, and the front bolt 310 passes through the front fixing hole 2141 and is tightened together with the front threaded hole 181. The bottom threaded hole 152 on the cabinet module 100 is located on the inside (upper side) of the bottom fixing hole 2131 on the refrigeration module 200, and the bottom bolt 330 passes through the bottom fixing hole 2131 and is tightened together with the bottom threaded hole 152. The rear fixing hole 151 on the cabinet module 100 is located on the outside (front side) of the rear threaded hole 2142 on the refrigeration module 200, and the rear bolt 320 passes through the rear fixing hole 151 and is tightened together with the rear threaded hole 2142. Based on this, the cabinet module 100 and the refrigeration module 200 can be completely fixed together by the front bolt 310, the rear bolt 320 and the bottom bolt 330.

As shown in Fig. 8 and Fig. 9, when the cabinet module 100 and the refrigeration module 200 are assembled, the roller 160 is embedded in the slot 2124, thereby limiting the movement of the cabinet module 100 in the front-to-back direction. The first upper plane 171 of the upper slide rail 170 abuts against the lower plane 2123 of the lower slide rail 212, so that the refrigeration module 200 bears the weight of the cabinet module 100 through the lower slide rail 212. Optionally, the upper inclined surface 173 of the upper slide rail 170 abuts against the second lower inclined surface 2122 of the lower slide rail 212, so as to further limit the movement of the cabinet module 100 in the front-to-back direction.

As shown in Figure 9, in some embodiments of the present invention, the refrigerator also includes a compressible and deformable sealing gasket 400 arranged between the top wall of the accommodating cavity 102 and the top surface of the shell 210. The sealing gasket 400 is squeezed by the cabinet module 100 and the shell 210 when the refrigerator is assembled, thereby eliminating the gap between the cabinet module 100 and the shell 210, making the abutment between the cabinet module 100 and the shell 210 more stable.

Preferably, the sealing gasket 400 covers the air supply port 2101 and the air return port 2102, and is provided with The avoidance holes are used to avoid the air supply port 2101 and the air return port 2102, so that the sealing gasket 400 can also seal the structure at the air supply port 2101 and the air return port 2102 to prevent air leakage.

In the present invention, the sealing pad 400 may be any feasible structure, such as foam, foam board, rubber pad, etc. Further, the sealing pad 400 may be fixedly connected to the box module 100, or may be fixedly connected to the refrigeration module 200. Alternatively, the sealing pad 400 may also include a portion fixedly connected to the box module 100 and a portion fixedly connected to the refrigeration module 200.

In some embodiments of the present invention, the vertical distance between the lowest position of the roller 160 and the first upper plane 171 is greater than the thickness of the sealing gasket 400 to prevent the sealing gasket 400 from interfering with the cabinet module 100 or the refrigeration module 200 during the installation of the cabinet module 100 and the refrigeration module 200.

Optionally, the vertical distance between the lowest position of the roller 160 and the first upper plane 171 is greater than the vertical distance between the lower plane 2123 and the top of the first lower inclined surface 2121. Alternatively, it can be understood by those skilled in the art that the vertical distance between the lowest position of the roller 160 and the first upper plane 171 is equal to the vertical distance between the lower plane 2123 and the top of the first lower inclined surface 2121, so that when the roller 160 rolls on the lower plane 2123, the first upper plane 171 and the top of the first lower inclined surface 2121 are in sliding contact, so that the box module 100 can be horizontally moved forward to a position where the roller 160 is embedded in the slot 2124 without the operator applying a vertical force thereto.

10 to 12 , the assembly of the cabinet module 100 and the refrigeration module 200 will be described in detail.

As shown in FIG. 10 , first, the cabinet module 100 is placed at the rear side of the refrigeration module 200 , and the cabinet module 100 is pushed from the rear to the front until the roller 160 moves to the first lower inclined surface 2121 .

Further, as the box module 100 is pushed forward, the roller 160 rolls to the top of the first lower slope 2121. Then, the roller 160 moves forward and downward along the second lower slope 2122. At this time, the operator can feel the movement of the roller 160.

As shown in Figures 10 and 11, as the box module 100 is pushed forward, the roller 160 rolls from the second lower inclined surface 2122 to the lower plane 2123. At this time, the first upper plane 171 of the upper slide rail 170 abuts against the top of the first lower inclined surface 2121. As the box module 100 is pushed forward, the roller 160 begins to roll on the lower plane 2123, and the upper slide rail 170 and the lower slide rail 212 are in sliding contact through the abutment of the top of the first lower inclined surface 2121 with the first upper plane 171. At this time, the operator only needs to apply a forward force to the box module 100 to make the box module 100 continue to move forward.

As shown in FIG. 12 , when the box module 100 moves to a position where the roller 160 is inserted into the slot 2124, the upper slide rail 170 contacts the lower plane 2123 of the lower slide rail 212 through its first upper plane 171, and the upper inclined surface 173 extends backward to the rear side of the second lower inclined surface 2122. At this time, the second lower inclined surface 2122 of the lower slide rail 212 contacts the upper slide rail 170. The upper inclined surface 173 of the second lower inclined surface 2122 abuts against the upper inclined surface 173, so that the abutment between the second lower inclined surface 2122 and the upper inclined surface 173 and the abutment between the roller 160 and the slot 2124 double fix the box module 100 in the front-rear direction. At the same time, the stopper 180 and the lower plane 2123 can also abut.

Those skilled in the art will appreciate that, in the process of the roller 160 being embedded in the slot 2124, the sealing gasket 400 will be gradually compressed, and as a result, the top end of the sealing gasket 400 will be displaced backward relative to the bottom end, so that the cross-section of the sealing gasket 400 perpendicular to the left and right directions is a parallelogram, which has a better sealing effect than the irregular deformation produced when the sealing gasket 400 is compressed.

At the same time, the portion of the sealing gasket 400 between the inner slope 1023 and the outer slope 2112 can be squeezed and deformed by the squeezing force in the horizontal direction, thereby preventing the structure at the air outlet 2101 from being deformed due to the influence of the gravity of the box module 100 .

Since the steps of removing the cabinet module 100 from the refrigeration module 200 are opposite to the above steps, that is, after removing the bolts 300, the cabinet module 100 can be removed from the refrigeration module 200 by simply pulling the cabinet module 100 backwards, no detailed description will be given here.

As shown in Figures 6 and 9, the shell 210 also includes a baffle 215 arranged above the lower sliding rail 212, and the block 180 and the baffle 215 are configured so that the block 180 can abut against the baffle 215 when the box module 100 forms a first angle with the horizontal plane and the roller 160 moves forward, and the block 180 will not abut against the baffle 215 when the box module 100 forms a second angle with the horizontal plane and the roller 160 moves forward.

The first angle is greater than the second angle. Optionally, the first angle has a value range of 5° to 30°. The second angle has a value range of 0° to 8°.

Continuing to refer to Figures 6 and 9, the baffle 215 includes a horizontal portion 2151 parallel to the lower plane and an inclined portion 2152 parallel to the second lower inclined surface 2122, so that the baffle 215 abuts against the block 180 through the inclined portion 2152, and limits the upward movement of the roller 160, the slide rail 170 and the block 180 through the horizontal portion 2151, thereby preventing the box module 100 from tipping over in the front and rear directions.

Those skilled in the art can understand that, by providing a stopper 180 on the cabinet module 100 located in front of the roller 160, providing a baffle 215 on the housing 210 located above the lower slide rail 212, and enabling the stopper 180 to abut against the baffle 215 when the cabinet module 100 forms a first angle with the horizontal plane and the roller 160 moves forward, the operator can clearly perceive that the cabinet module 100 needs to be lifted to a certain angle. By enabling the stopper 180 not to abut against the baffle 215 when the cabinet module 100 forms a second angle with the horizontal plane and the roller 160 moves forward to the top of the first lower slope 2121, it is ensured that the cabinet module 100 can be moved to a position that matches the refrigeration module 200.

In addition, in other embodiments of the present invention, those skilled in the art may also omit the above-mentioned steps as required. The second upper plane 172 on the rail 170, and/or the second lower inclined surface 2122 on the lower rail 212 is omitted.

As shown in FIG. 13 , in some embodiments of the present invention, the air supply duct 130 includes a portion located in the first inner liner 110, a portion located in the second inner liner 120, and a portion located outside the two inner liner. In addition, the portion of the air supply duct 130 located in the first inner liner 110 is provided with an air outlet communicating with the first storage compartment 1011, and the portion of the air supply duct 130 located in the second inner liner 120 is provided with an air outlet communicating with the second storage compartment 1012.

Of course, in other embodiments of the present invention, those skilled in the art may also set the air supply pipeline 130 to any other feasible form as needed. The air supply pipeline 130 is completely set outside the first inner liner 110 and the second inner liner 120 .

The refrigeration module 200 of the present invention will be further described in detail below with reference to FIGS. 4 to 6 and 14 to 17 .

As shown in FIGS. 4 to 6, 14 and 15, in some embodiments of the present invention, a press chamber 2103, a refrigeration chamber 2104, a heat dissipation air inlet channel 2105 and a heat dissipation air outlet channel 2106 are defined in the housing 210. The heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are respectively connected to the press chamber 2103 and extend from the press chamber 2103 to the front end of the housing 210.

It should be noted here that, in order to facilitate the understanding of those skilled in the art, FIG. 14 schematically shows the relative position relationship and distribution of the four spaces of the compressor chamber 2103 , the refrigeration chamber 2104 , the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 .

It is not difficult to see from FIG. 14 that the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are all located below the refrigeration room 2104, and the outer contours of the projections of the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane are located outside the projection of the refrigeration room 2104 on the horizontal plane. In other words, if the press chamber 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are regarded as a whole, the projection of the refrigeration room 2104 on the horizontal plane is located inside the projection of the whole on the horizontal plane.

As shown in Fig. 4, the air supply port 2101, the front air return port 21021 and the side air return port 21022 are respectively connected to the refrigeration compartment 2104. The air supply port 2101 is located at the upper rear of the refrigeration compartment 2104, the front air return port 21021 is located at the upper front of the refrigeration compartment 2104, and the side air return port 21022 is located at the upper side of the refrigeration compartment 2104.

As shown in FIG. 15 , in some embodiments of the present invention, the refrigeration system 220 includes a compressor 221, a high-temperature pipeline 222, a condenser 223, a drying filter 224, a capillary tube 225, an evaporator 226 and a return air pipe 227 which are connected end to end in sequence to form a closed loop.

As shown in Figures 15 to 17, the compressor 221, the condenser 223 and the filter drier 224 are all arranged in the compressor compartment 2103, the high temperature pipeline 222 is distributed in the compressor compartment 2103 and the heat dissipation and air outlet channel 2106, and the evaporator 226 is arranged in the refrigeration room 2104. Most of the pipe sections of the capillary tube 225 and the return air pipe 227 are located in the compressor compartment 2103. and the outside of the refrigeration chamber 2104. Alternatively, those skilled in the art may also dispose all of the capillary tube 225 and/or the return air pipe 227 on the outside of the press chamber 2103 and the refrigeration chamber 2104 as required.

As shown in FIGS. 16 and 17 , the heat dissipation fan 230 is arranged in the compressor chamber 2103, the air supply fan 240 is arranged in the refrigeration chamber 2104, and the evaporation dish 250 is arranged in the heat dissipation air outlet channel 2106. At least a part of the portion of the high-temperature pipeline 222 located in the heat dissipation air outlet channel 2106 is located in the evaporation dish 250, so that the high-temperature pipeline 222 can heat the water in the evaporation dish 250 to promote the evaporation of the water.

As shown in FIG. 17 , in some embodiments of the present invention, a transverse gap (not marked in the figure) is formed between the top plates of the compressor chamber 2103, the heat dissipation air inlet channel 2105, and the heat dissipation air outlet channel 2106 and the bottom plate of the refrigeration chamber 2104, and the transverse gap is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton). A front gap (not marked in the figure) is formed between the bottom of the front side plate of the refrigeration chamber 2104 and the outer side plate of the housing 210 adjacent thereto, and the front gap is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton). A longitudinal gap (not shown in the figure) is formed between the left side plate and the right side plate of the refrigeration chamber 2104 and the outer side plate of the housing 210 adjacent thereto, and the longitudinal gap is filled with a heat-insulating material (such as a foaming agent or a heat-insulating cotton). It can be understood by those skilled in the art that the heat-insulating material outside the refrigeration chamber 2104 can effectively insulate the refrigeration chamber 2104 and prevent it from leaking cold.

Optionally, the capillary tube 225 and the return air pipe 227 are arranged in the longitudinal gap and wrapped with a heat-insulating material. Preferably, the capillary tube 225 and the return air pipe 227 are in contact with each other so that the two can exchange heat. Further, since the temperature of the heat dissipation air inlet channel 2105 is lower than the temperature of the heat dissipation air outlet channel 2106, the capillary tube 225 and the return air pipe 227 are preferably arranged in one of the two longitudinal gaps close to the heat dissipation air inlet channel 2105.

As shown in FIG. 17 , the refrigeration module 200 further includes a pressing plate 260 disposed between the evaporator 226 and the top plate of the refrigeration compartment 2104 , and the pressing plate 260 is used to press the evaporator 226 onto the bottom plate of the refrigeration compartment 2104 , thereby fixing the evaporator 226 in the refrigeration compartment 2104 at an angle.

Continuing to refer to FIG. 17 , in some embodiments of the present invention, a drain hole (not marked in the figure) is provided on the bottom plate of the refrigeration chamber 2104 below the front portion of the evaporator 226. The refrigeration module 200 further includes a drain pipe 270 connected to the drain hole and extending from top to bottom into the evaporation dish 250, so that the drain pipe 270 can quickly discharge the defrost water in the refrigeration chamber 2104 into the evaporation dish 250.

It can be seen from FIG. 10 and FIG. 12 that there is a gap between the bottom plate of each of the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 and the bearing surface (such as the ground or floor).

As shown in FIGS. 4 to 6 , the heat dissipation air inlet channel 2105 includes a plurality of front air ports 21051 formed on the front side plate of the housing 210, so that the outside air can enter the heat dissipation air inlet channel 2105 from the plurality of front air ports 21051. Further, the heat dissipation air inlet channel 2105 also includes a plurality of front air ports 21051 formed on the bottom plate of the heat dissipation air inlet channel 2105. The bottom air inlets 21052 are provided to allow external air to enter the heat dissipation air inlet channel 2105 through the gap below the heat dissipation air inlet channel 2105 and the multiple bottom air inlets 21052 .

It is understood by those skilled in the art that, since the heat dissipation air inlet channel 2105 has a plurality of front air inlets 21051 located at the front side thereof and a plurality of bottom air inlets 21052 located at the bottom side thereof, the air inlet capacity of the heat dissipation air inlet channel 2105 is improved and the wind resistance is reduced. This not only avoids the problem of poor air inlet due to the limitation of the front side plate area of the heat dissipation air inlet channel 2105 when the heat dissipation air inlet channel 2105 only has a plurality of front air inlets 21051; it also avoids the problem of the bottom air inlet 21052 being blocked due to the accumulation of dust, lint and other debris at the bottom air inlet 21052 when the heat dissipation air inlet channel 2105 only has a plurality of bottom air inlets 21052, thereby preventing the heat dissipation air inlet channel 2105 from obtaining sufficient air.

As shown in FIGS. 4 to 6 , the heat dissipation air outlet channel 2106 includes a plurality of front air outlets 21061 formed on the front side plate of the housing 210, so that the hot air in the heat dissipation air inlet channel 2105 can flow out to the outside through the plurality of front air outlets 21061. Optionally, the heat dissipation air outlet channel 2106 includes a plurality of bottom side air outlets (not shown in the figure) formed on the bottom plate thereof.

As shown in FIG. 6 , the housing 210 further includes a wind shield 216 disposed on the bottom side of the bottom plate of the compressor chamber 2103 , and the wind shield 216 is used to prevent the bottom air inlet 21052 from sucking in hot air blown out from the front air outlet 21061 .

As shown in FIG6 and FIG16, the bottom plate of the compressor chamber 2103 is provided with a plurality of bottom air inlets 21031 on the windward side of the condenser 223, and the bottom plate of the compressor chamber 2103 is provided with a plurality of bottom air outlets 21032 on the side of the heat dissipation fan 230 away from the condenser 223. In addition, the plurality of bottom side air inlets 21052 and the plurality of bottom air inlets 21031 are located on one side of the wind shield 216, and the plurality of bottom air outlets 21032 are located on the other side of the wind shield 216. Based on this, it can be understood by those skilled in the art that the outside air can also enter the compressor chamber 2103 through the bottom air inlet 21031, and a part of the hot air in the compressor chamber 2103 will flow to the outside from the bottom air outlet 21032.

As can be seen from FIG. 16 , in some embodiments of the present invention, a portion of the plurality of bin bottom air outlets 21032 are located below the compressor 221, and another portion of the plurality of bin bottom air outlets 21032 are located in front of the compressor 221. Furthermore, the plurality of bin bottom air outlets 21032 located in front of the compressor 221 are adjacent to the evaporation dish 250.

It is understood by those skilled in the art that the airflow blocked by the rear side panels of the evaporating dish 250 can be reflected to the multiple bottom air outlets 21032 on the front side of the compressor 221, and then flow to the outside from the multiple bottom air outlets 21032. Compared with the structure without the bottom air outlets 21032 on the rear side of the evaporating dish 250, this structure can effectively avoid the blocking effect of the rear side panels of the evaporating dish 250 on the airflow, and thus effectively avoid the airflow from cyclones at the rear side panels of the evaporating dish 250. Therefore, in some embodiments of the present invention, the obstruction of the rear side panels of the evaporating dish 250 on the airflow can be effectively eliminated, and the corresponding noise can be eliminated.

As shown in FIG. 16 , in some embodiments of the present invention, the evaporation dish 250 has a horizontal structure and a scattering structure. The structures of the hot air outlet channel 2106 in the horizontal direction are adapted, that is, the sides of the evaporating dish 250 and the heat dissipating air outlet channel 2106 that are opposite to each other are parallel, so that the evaporating dish 250 can cover the entire heat dissipating air outlet channel 2106 as much as possible, thereby increasing the evaporation area of the evaporating dish 250 and improving the evaporation rate of water in the evaporating dish 250.

Optionally, the size of the evaporating dish 250 in the front-to-back direction is greater than the size of the evaporating dish 250 in the left-to-right direction, so that the evaporating dish 250 has a sufficient length on the path of air flow in the heat dissipation air outlet channel 2106, thereby increasing the contact time between water in the evaporating dish 250 and the airflow, and improving the evaporation rate of the water in the evaporating dish 250.

Furthermore, the width of the front portion of the evaporating dish 250 gradually decreases from the back to the front, and the width of the front portion of the heat dissipation air outlet channel 2106 also gradually decreases from the back to the front, so that the flow area of the front portion of the heat dissipation air outlet channel 2106 gradually decreases, thereby gradually increasing the flow rate of the airflow at the front portion of the evaporating dish 250, so as to ensure the evaporation rate of the water in the front portion of the evaporating dish 250.

Those skilled in the art can understand that, in the heat dissipation air outlet channel 2106, since the temperature of the airflow is high when it just enters the evaporation dish 250, it has a good heating effect on the water in the evaporation dish 250; however, as the airflow gradually approaches the front air outlet 21061, the airflow absorbs more and more heat from the water, and the temperature becomes lower and lower, resulting in a poor heating effect on the water. By gradually reducing the width of the front of the evaporation dish 250 and the heat dissipation air outlet channel 2106 from back to front, the flow area of the front of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow rate of the airflow therein is gradually increased, so that the airflow can overcome the effect of low temperature on the evaporation efficiency of water at a high flow rate. Therefore, in some embodiments of the present invention, by gradually reducing the width of the front of the evaporation dish 250 and the heat dissipation air outlet channel 2106 from back to front, the evaporation efficiency of the airflow in the heat dissipation air outlet channel 2106 on the water in the evaporation dish 250 is improved.

As shown in FIG. 17 , in some embodiments of the present invention, a water receiving pipe 251 extending upward from the bottom plate of the evaporating dish 250 is provided in the evaporating dish 250. The lower end of the drain pipe 270 is inserted into the water receiving pipe 251, and there is a gap between the water receiving pipe 251 and the drain pipe 270, so that water flowing out of the drain pipe 270 can flow out of the water receiving pipe 251 through the gap and flow into the evaporating dish 250.

It is understood by those skilled in the art that, since the lower end of the drain pipe 270 is inserted into the water receiving pipe 251, a small amount of water will be stored in the water receiving pipe 251 after the evaporator 226 is defrosted to seal the bottom end of the drain pipe 270, that is, the liquid level in the water receiving pipe 251 is located above the bottom end of the drain pipe 270. It is further understood by those skilled in the art that, since the bottom end of the drain pipe 270 is sealed by water, the hot air in the evaporating dish 250 cannot enter the refrigeration chamber 2104 from the drain pipe 270, thereby improving the refrigeration efficiency of the refrigeration module 200.

Based on the above description, those skilled in the art can understand that, in the present invention, by providing a receiving chamber 102 at the bottom of the box module 100, and providing at least one on the left and right walls of the receiving chamber 102, respectively. Roller 160; lower rails 212 extending forward and backward are respectively arranged on the left and right sides of the housing 210 of the refrigeration module 200, so that the cabinet module 100 can slide forward from the rear side of the refrigeration module 200 to a position matching with the refrigeration module 200 by means of rolling contact between the roller 160 and the lower rail 212, so that the refrigeration module 200 is embedded in the accommodating cavity, thereby realizing the assembly of the cabinet module 100 and the refrigeration module 200. Therefore, the refrigerator of the present invention does not need to use lifting equipment to move the cabinet module 100 to the refrigeration module 200, which not only improves the assembly efficiency of the refrigerator, but also reduces the assembly difficulty of the operator.

Furthermore, by forming a chamfer between the front side and the bottom of the stopper 180, when the cabinet module 100 is removed from the refrigeration module 200, the rear part of the cabinet module 100 is moved upward so that the chamfer can abut against the lower slide rail 212 and serve as a fulcrum to slide the roller 160 out of the slot 2124. At the same time, the contact friction between the chamfer and the lower slide rail 212 is smaller than that between the right angle and the lower slide rail 212, making it easier for the cabinet module 100 to slide on the lower slide rail.

Furthermore, by making the bottom surface of the upper slide rail 170 further include a second upper plane located at the rear side of the upper inclined surface 173, when the cabinet module 100 is removed from the refrigeration module 200, the rear part of the cabinet module 100 can be pressed downward, so that the concave structure formed between the second upper plane 172 and the upper inclined surface clamps the protrusion between the first lower inclined surface 2121 and the second lower inclined surface 2122 and uses it as a fulcrum. Then, the operator can pull the cabinet module 100 backward to make the roller slide out of the clamping slot 2124.

So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and/or technical principles of the present invention will fall within the protection scope of the present invention.
