The module body includes an evaporator compartment 600 and a compressor compartment 700. An evaporator 601 is disposed in the evaporator compartment 600. The compressor compartment 700 is disposed separately from the evaporator compartment 600. A compressor 701 and a condenser 703 are disposed in the compressor compartment 700. The mounting space includes a space defined by the evaporator compartment 600 and a space defined by the compressor compartment 700.

The air return port is used for introducing the air into the containing cavity 630, and the air return port and the cold supply port are correspondingly disposed in the front and rear ends of the cover plate 620, so that the air can be cooled by the evaporator 601 as much as possible when flowing from the front side to the rear side of the evaporator 601; similarly, the air return port is disposed into a structure extending in the up-down direction so that the space required by the whole unit in the horizontal direction is reduced.
In some embodiments, an electrical connection port is further formed in the rear end of the cover plate 620 in the up-down direction, the electrical connection port is configured to be detachably connected to an external pipeline 500 having a power supply line, and the power supply line is introduced into the refrigeration module 202 via the electrical connection port; the electrical connection port is formed in the lateral portion of the cold supply port in a transverse direction. Similarly, the electrical connection port is disposed into a structure extending in the up-down direction, so that the space required by the whole unit in the horizontal direction can be reduced. The electric connection port is formed in the lateral portion of the cold supply port in the transverse direction, considering that water vapor nearby the cold supply port is little, it is possible to avoid excessive contact of the power supply line with the water vapor and improve the power distribution safety; at the same time, the compressor compartment 700 is disposed behind the evaporator compartment 600, and the electrical connection port is disposed in the rear end of the cover plate 620, so that the power supply line can be conveniently introduced into the compressor compartment 700, which can shorten the total length of the power supply line, and save costs.

The flowing direction of the airflow in the refrigeration module 202 is shown by an arrow in
The refrigeration module 202 further includes: a special-shaped plate 706 having a bottom horizontal section 761 located at the bottom front side of the refrigeration module 202; the front end of the second section 752 is connected with the bottom horizontal section 761 such that the supporting plate 705 and the bottom horizontal section 761 jointly form the bottom wall of the refrigeration module 202. The special-shaped plate 706 also has a bent section 762 bent and extending upwards and backwards from the rear end of the bottom horizontal section 761; the bent section 762 extends to a position above the supporting plate 705, and forms the top of the compressor compartment 700. The supporting plate 705 and the special-shaped plate 706 are disposed so that the supporting plate 705 and the bottom horizontal section 761 jointly constitute the bottom wall of the refrigeration module 202, and the bottom air inlet 710 and the bottom air outlet 720 are disposed in the front end portion of the supporting plate 705; the bottom air inlet 710 and the bottom air outlet 720 can be respectively formed by a plurality of ventilation holes so as to prevent the refrigeration module 202 against rats; at the same time, this structure can greatly simplify the mounting process of the refrigeration module 202, and only the compressor 701, the heat dissipation fan 702, the condenser 703, etc. need to be integrated on the supporting plate 705, and then the supporting plate 705 and the special-shaped plate 706 are integrated, namely, mounting of the bottom wall of the refrigeration module 202 is completed. The bent section 762 includes a first inclined section 7621, a second inclined section 7622, a third inclined section 7623 and a top horizontal section 7624, wherein the first inclined section 7621 extends upwards from the rear end of the bottom horizontal section 761, the second inclined section 7622 extends backwards and upwards from the upper end of the first inclined section 7621, the third inclined section 7623 extends backwards and upwards from the upper end of the second inclined section 7622, and the top horizontal section 7624 extends backwards from the upper end of the third inclined section 7623 to cover a position above the first section 751 of the supporting plate 705. The slope structure of the bent section 762 can guide and rectify air inflow airflow, so that the airflow entering from the bottom air inlet 710 flows to the condenser 703 in a more concentrated mode, which avoids that the airflow is too dispersed and cannot pass through the condenser 703 more, thereby further ensuring the heat dissipation effect of the condenser 703; at the same time, the slope structure of the bent section 762 guides the air outflow airflow of the bottom air outlet 720 to the front side of the bottom air outlet 720, so that the air outflow airflow flows more smoothly out of the compressor compartment 700, thereby further improving the circulating smoothness of the airflow. In addition, side ventilation holes 730 are formed in both side plates of the compressor compartment 700 in the transverse direction to increase a heat dissipation path to ensure the heat dissipation effect of the compressor compartment 700. The side ventilation holes 730 may be covered with a ventilation cover plate which forms small grid-type ventilation holes.
As shown in
The plate section of the rear wall (namely, the back plate 707) of the compressor compartment 700 corresponding to the condenser 703 is designed into a continuous plate surface, and heat dissipation airflow entering the compressor compartment 700 is closed at the condenser 703, so that the ambient air entering from the bottom air inlet 710 is more concentrated at the condenser 703, which ensures the heat exchange uniformity of each condensation section of the condenser 703, facilitates forming a better heat dissipation airflow path, and also achieves a better heat dissipation effect. Moreover, the plate section of the back plate 707 facing the condenser 703 is the continuous plate surface and is not provided with the air inlet, so that the problems that in the conventional design, air outlet and air inlet are both concentrated at the rear part of the compressor compartment 700, which causes that the hot air blown from the compressor compartment 700 is not cooled by the ambient air in time and enters the compressor compartment 700 again, causing adverse effects on heat exchange of the condenser 703 are avoided, and thus the heat exchange efficiency of the condenser 703 is guaranteed.
With reference to
At least a part of the air supply pipeline 300 and/or the air return pipeline 400 is a vacuum pipe 800.
The outer pipe 801 is made of a metal pipe fitting; the inner pipe 802 is made of a metal pipe fitting; the end sealing connection piece 803 is made of quartz glass. The two layers of pipes are both metal pipes, which can stabilize the structure of the vacuum pipe 800. Preferably, both the outer pipe 801 and the inner pipe 802 are stainless steel pipes, for example, 304 stainless steel. The stainless steel pipe can ensure the strength of the vacuum pipe 800, is attractive in appearance, can reduce radiation heat transfer, and can avoid air leakage caused by corrosion and rusting at the same time. The end sealing connection piece 803 is made of quartz glass and has the characteristics of low thermal conductivity and low outgassing rate, which can solve the thermal bridge heat transfer problem of the vacuum pipe 800.
The thickness of the outer pipe 801 and the thickness of the inner pipe 802 may be the same or may be different. The outer pipe 801 has a thickness of 1 mm to 1.5 mm, such as 1 mm, 1.2 mm, and 1.5 mm. The inner pipe 802 has a thickness of 1 mm to 1.5 mm, such as 1 mm, 1.2 mm, and 1.5 mm. The end sealing connection piece 803 may be an annular component, and the portion of the end sealing connection piece 803 sandwiched between the outer pipe 801 and the inner pipe 802 has a length of 10 mm to 15 mm, such as 10 mm, 12 mm, and 15 mm. Through a large number of experimental studies, it is preferable to limit the length of the end sealing connection piece 803 between the outer pipe 801 and the inner pipe 802 in the range of 10 mm to 15 mm, which can ensure that the end sealing connection piece 803 seals tightly the outer pipe 801 and the inner pipe 802, and at the same time can avoid that because the end sealing connection piece 803 is too large, the volume of the vacuum cavity 810 is reduced, so that the thermal insulation effect of a vacuum thermal insulator 100 is good. The distance between the outer pipe 801 and the inner pipe 802 is 0.5 mm to 20 mm, for example, 0.5 mm, 2 mm, 5 mm, 10 mm, 15 mm, and 20 mm. Setting the distance between the outer pipe 801 and the inner pipe 802 to be 0.5 mm-20 mm can satisfy different thermal insulation and product requirements. The inner diameter of the inner pipe 802 is 3-5 times the distance between the outer pipe 801 and the inner pipe 802.

The vacuum thermal insulator 100 may also include: a plurality of supporting pieces 105, disposed in the vacuum cavity 110, and configured to be fixed to the first plate 101 and/or the second plate 102 to provide supporting between the first plate 101 and the second plate 102. By disposing the plurality of supporting pieces 105 in the vacuum cavity 110, the first plate 101 and the second plate 102 can be supported, which enhances the strength of the entire vacuum thermal insulator 100; the supporting piece 105 is directly fixed to the first plate 101 and/or the second plate 102, so that the disposing process of the supporting piece 105 is simplified and the manufacturing process of the entire vacuum thermal insulator 100 is simplified. The supporting piece 105 is preferably made of quartz glass or polytetrafluoroethylene, and is adhesively fixed to the first plate 101 and/or the second plate 102 by using epoxy resin or silica gel.
The composition and manufacturing method of the vacuum thermal insulator 100 of the present invention are briefly described below. The first plate 101 is made of a stainless steel plate, and the second plate 102 is made of a stainless steel plate. A stainless steel plate with the inner surface being a mirror surface or being evaporated may be used, for example, 304 stainless steel. The stainless steel plate can ensure the strength of the vacuum thermal insulator 100, is attractive in appearance, can reduce radiation heat transfer, and can avoid air leakage caused by corrosion and rusting at the same time. The sealing connection piece 103 is made of quartz glass and the quartz glass has the characteristics of low thermal conductivity and low outgassing rate, which can solve the thermal bridge heat transfer problem of the vacuum thermal insulator 100. A sealing structure 104 is also formed between the first plate 101 and the second plate 102 and the sealing connection piece 103. Since the thermal expansion coefficients of the quartz glass and the stainless steel plate are different by 15 times, the sealing structure 104 needs to be elastic and can be tightly combined with the quartz glass and the stainless steel plate so as to ensure tight connection between the quartz glass and the stainless steel plate. The sealing structure 104 may include a nickel plated layer and a solder piece; the upper and lower surfaces of the sealing connection piece 103 respectively form the nickel plating layer, a silver-copper solder piece is arranged between the nickel plated layer and the first plate 101 and the second plate 102, and the sealing connection piece is sealed and fixed to the first plate 101 and the second plate 102 by welding the nickel plated layer and the silver-copper solder piece.

The sealing structure 104 may further include a quick-drying silica gel layer; the silica gel layer is respectively disposed between the sealing connection piece 103 and the first plate 101 and the second plate 102, and the sealing connection piece 103 is sealed and fixed to the first plate 101 and the second plate 102 by bonding the silica gel layer.
A first frame 230 is configured to wrap the end of the first vacuum thermal insulator 111, wherein the side of the first frame 230 away from the first vacuum thermal insulator 111 is provided with a metal strip 240 for magnetically attracting and sealing a door seal 260. The first frame 230 is provided with a groove (not numbered in the figure) on a side away from the first vacuum thermal insulator 111, and the metal strip 240 is adhesively fixed to the first frame 230. The metal strip 240 may be stainless steel or carbon steel electroplated with dimensions of a width about 10 mm*a thickness of 2 mm. The metal strip 240 may be adhesively fixed to the first frame 230 by using quick-drying silica gel. The first sealing connection piece 131 has a first section 1311 located between the outer shell 211 and the inner shell 212, and a second section 1312 going beyond the ends of the outer shell 211 and the inner shell 212; the first frame 230 is configured to be cooperatively fixed to the second section 1312, thereby being fixed to the first vacuum thermal insulator 111. The first frame 230 is preferably fixed to the second section 1312 in a clamped connection mode, which has the advantages of simple structure and convenient mounting. The assembly process of the cabinet 210 is firstly sealing and fixing the first sealing connection piece 131 to the outer shell 211 and the inner shell 212 and vacuumizing to form the first vacuum thermal insulator 111; then, fixing the first frame 230 to which the metal strip 240 is adhered with the first vacuum thermal insulator 111 in a clamped connection mode. The width of the first section 1311 is preferably 10 mm-15 mm, which can ensure that the first sealing connection piece 131 tightly seals the outer shell 211 and the inner shell 212, and at the same time can prevent that the first sealing connection piece 131 is too large, and consequently the volume of the vacuum cavity 110 is reduced, so that the heat insulation effect of the first vacuum thermal insulator 111 is good. The width of the second section 1312 is about 10 mm, so that the first vacuum thermal insulator 111 can be stably assembled with the first frame 230 without too much heat leakage. The first frame 230 can be made of an ABS material, a PP material, etc. A groove 231 is formed on the inner side face of the first frame 230 close to the first vacuum thermal insulator 111 at a position corresponding to the end of the second section 1312; the end of the second section 1312 is clamped into the groove 231 of the first frame 230. In addition, the second section 1312 respectively forms grooves 1313 on its outer side surface located on one side of the outer shell 211 and on its inner side surface located on one side of the inner shell 212; a protrusion 232 is respectively formed on the inner side surface of the first frame 230 close to the first vacuum thermal insulator 111 at a position corresponding to the groove 1313 of the second section 1312; the protrusion 232 is fixed to the groove 1313 of the second section 1312 in a clamped connection mode. By the double groove and protrusion structure, stable connection of the frame and the first vacuum thermal insulator 111 can be achieved. The tail end of the protrusion 232 of the first frame 230 may be disposed into a sharp corner portion to be used as undercut to facilitate being clamped into the groove 1313 of the second section 1312 during assembly. At the same time, after mounting is completed, the first frame 230 and the first vacuum thermal insulator 111 are bounded by the protrusion 232 of the first frame 230 to define two cavity-like structures 233 so as to play a heat insulating role and block heat leakage at the first frame 230. The side of the first sealing connection piece 131 located on the outer shell 211 may be regarded as the outer side surface of the first sealing connection piece 131, and the side located on the inner shell 212 may be regarded as the inner side surface of the first sealing connection piece 131, wherein the outer side surface of the first section 1311 is attached to the outer shell 211, and the outer side surface of the second section 1312 faces the side where the outer shell 211 is located; the inner side surface of the first section 1311 is attached to the inner shell 212, and the inner side surface of the second section 1312 faces the side where the inner shell 212 is located.

The tail end of the outer plate 221 of the door body 220 is bent such that the end of the outer plate 221 is disposed opposite to the end of the inner plate 222 with a gap. A second frame 250 is configured to be fixed to the second vacuum thermal insulator 112 through a gap, and a door seal 260 is mounted on the side of the second frame 250 away from the second vacuum thermal insulator 112. The structure of the door body 220 is ingenious, and by bending the outer plate 221, the gap is defined between the outer plate 221 and the inner plate 222, and the second frame 250 is fixed to the second vacuum thermal insulator 112 in cooperation via the gap, the second frame 250 and the second vacuum thermal insulator 112 can be firmly fixed, and at the same time, the door body 220 can be kept integrated in appearance, so as to improve the sensory experience of the user. The assembly process of the door body 220 is firstly sealing and fixing the second sealing connection piece 132 to the outer plate 221 and the inner plate 222 and vacuumizing to form the second vacuum thermal insulator 112; then fixing the second frame 250 to the second vacuum thermal insulator 112, and finally, fixing the door seal 260 to the second frame 250. The height of the second sealing connection piece 132 is preferably 10 mm-15 mm, which can ensure that the second sealing connection piece 132 seals tightly the outer plate 221 and the inner plate 222, and at the same time can prevent that the second sealing connection piece 132 is too large, and consequently the volume of the vacuum cavity 110 is reduced, so that the heat insulation effect of the second vacuum thermal insulator 112 is good. The second frame 250 can be made of an ABS material, a PP material etc. Specifically, the projection of the end of the second sealing connection piece 132 in the vertical direction is between the end of the outer plate 221 and the end of the inner plate 222; the second frame 250 has a first frame portion 251 and a second frame portion 252, the first frame portion 251 is clamped into a space defined by the outer plate 221, the gap and the second sealing connection piece 132, and the second frame portion 252 extends from the first frame portion 251 toward the side away from the second vacuum thermal insulator 112. The side face of the second frame portion 252 away from the first frame portion 251 is recessed inwards to form an accommodating cavity 2521; the door seal 260 is fixed to the second frame 250 through the accommodation cavity 2521. The door seal 260 includes an air bag 261, a base 262 and a magnetic strip 263, wherein the base 262 extends from the air bag 261 towards the door body 220 and is accommodated in the accommodation cavity 2521; the magnetic strip 263 is disposed on the air bag 261 and matched with the metal strip 240 to attract the dock seal 260 onto the cabinet 210.
The matching structure of the air supply pipeline 300, the air return pipeline 400, and the threading pipeline 500 with the cabinet 210 when the cabinet 210 of the storage portion 201 is the vacuum thermal insulator 100 will be described below.
An air supply joint 341 is disposed outside the outlet end of the air supply pipeline 300, and the air supply joint 341 passes through an air supply mounting opening formed in the cabinet 210. The fixing piece 351 is matched with the air supply joint 341 by threaded connection in the cabinet 210, thereby fixing the air supply pipeline 300 to the air supply joint 341. The air supply pipeline 300 and the cabinet 210 are fixed by the cooperation of the air supply joint 341 and the fixing piece 351, so that the structure is ingenious, mounting is simple and stability is good. Specifically, the end sealing connection piece 803 has the first section 831 located between the outer pipe 801 and the inner pipe 802, and the second section 832 beyond the ends of the outer pipe 801 and the inner pipe 802. The air supply joint 341 is matched with the second section 832 of the end sealing connection piece 803 in a clamped connection mode. The air supply joint 341 has a joint base 3411 and a joint protrusion 3412, the inner side surface of the joint base 3411 is attached to the outer shell 211, the end of the joint protrusion 3412 goes beyond the inner shell 212 and the outer side surface of the portion going beyond is provided with a threaded structure corresponding to the threaded structure of the fixing piece 351. A rubber sealing ring 360 is further disposed in a contact area between the air supply joint 341 and the cabinet 210. In particular, the outer shell 211 and the inner shell 212 of the cabinet 210 are provided with quartz glass heat insulation pieces 203 around the air supply mounting opening by one circle to improve heat transfer at the air supply mounting opening. The heat insulation piece 203 is an annular component, and the annular width may be 10±5 mm, preferably 10 mm to 15 mm. The annular width of the heat insulation piece 203 is 10 mm to 15 mm, which can ensure that the heat insulation piece 203 tightly seals the outer shell 211 and the inner shell 212, and at the same time can avoid that because the heat insulation piece 203 is too large, the volume of the vacuum cavity 110 is reduced, so that the heat insulation effect of the vacuum thermal insulator 100 is good. It will be appreciated that the heat insulation piece 203 may essentially be considered as the sealing connection piece 103 at the opening in the vacuum thermal insulator 100, and the heat insulation piece 203 is sandwiched between the first plate 101 and the second plate 102 to seal the vacuum thermal insulator 100 at the opening.

Similarly, the cabinet 210 is provided with an air return mounting opening, and the air return pipeline 400 is fixed to the cabinet 210 at the air return mounting opening through cooperation of an air return joint and the fixing piece.
A threading joint 531 is disposed on the outside of the threading pipeline 500 close to the cabinet 210, and the threading joint 531 passes through an electrical connection mounting opening formed in the cabinet 210. The fixing piece 541 is matched with the threading joint 531 by threaded connection in the cabinet 210, so as to fix the threading pipeline 500 to the cabinet 210. The threading pipeline 500 is fixed to the cabinet 210 by the cooperation of the threading joint 531 and the fixing piece 541, so that the structure is ingenious, mounting is simple, and the stability is good. Specifically, the threading joint 531 has a joint base 5311 and a joint protrusion 5312. The inner side surface of the joint base 5311 is attached to the outer side surface of the outer shell 211. The end of the joint protrusion 5312 goes beyond the inner shell 212 and the outer side surface of the portion going beyond is provided with a threaded structure corresponding to the threaded structure of the fixing piece 541. The threading pipeline 500 and the threading joint 531 can be integrally injection-molded to reduce assembly steps and improve assembly efficiency. The threading joint 531 may be made of a PVC material. The fixing piece 541 may be made of an ABS or PS material. Likewise, the outer shell 211 and the inner shell 212 of the cabinet 210 are provided with quartz glass heat insulation pieces 203 around the electrical connection mounting opening by one circle, so as to improve the heat transfer at the electrical connection mounting opening.
The refrigeration module 202 of the embodiment of the present invention has the module body in which the mounting space is defined, and the refrigeration system for generating cooling capacity is disposed in the mounting space. Since the cold supply port is disposed in the module body, and the cold supply port is configured to be detachably connected to the external pipeline 300, the cooling capacity generated by the refrigeration system is supplied into the external pipeline 300 by the cold supply port. The refrigeration module 202 can be sold and used independently, and the using experience of the user can be improved especially when it is used as a part of the split refrigerator 200.
By separately disposing the refrigeration module 202 and the storage portion 201 of the refrigerator 200 of the embodiment of the present invention, the storage portion 201 does not need to give way for the refrigeration system, which can greatly increase the internal volume of the refrigerator 200; the refrigeration module 202 is independently disposed and may be free to match with one or more same or different storage portions 201 as desired
