[0053] The following is combined with Figures 1 to 14 The utility model is described in further detail.

[0054] Reference Figure 1 As shown, the refrigeration device 1000 provided in the embodiment of the utility model can be one of the refrigeration devices 1000 such as a refrigerator, a freezer or a wine cabinet. The refrigeration device 1000 includes a box body 100, and a door body 200 is located in front of the box body 100. The door body 200 is pivotally connected to the box body 100 to open or close the box body 100. The box body 100 includes an outer shell and an inner liner. The outer shell is located at the outermost side of the entire refrigeration device 100 to protect the refrigeration device 1000. The outer shell includes a bottom plate and a back plate 103. The inner liner is wrapped by the outer shell, and the space between the inner liner and the outer shell is filled with insulation material to form an insulation layer 104 to reduce the loss or transfer of heat in the inner liner to the outside. A storage chamber 110 can be defined in the inner liner, and the storage chamber 110 is not limited to Figure 1 The number of the plurality of storage chambers 110 may be any number, such as one, three, five, etc. When there is one storage chamber 110, the storage chamber 110 may be a cooling chamber 120, a temperature-changing chamber, or a refrigerating chamber. When there are two or more storage chambers 110, the plurality of storage chambers 110 may include at least one of a cooling chamber 120, a temperature-changing chamber, and a refrigerating chamber.

[0055] It is understandable that, referring to Figure 1 , Figure 4 and Fig. 9As shown, the box body 100 is further provided with a cooling chamber 120, a machine chamber 130 and an installation chamber 140. The cooling chamber 120 is mainly used to install components such as the evaporator 300, the machine chamber 130 is mainly used to install mechanical components such as the compressor 400, and the installation chamber 140 is mainly used to install the condenser 500 or the electric control box 600. Specifically, the cooling chamber 120 and the machine chamber 130 are located below the storage chamber 110, and are located on the same side of the machine chamber 130 in the front-to-back direction, and the installation chamber 140 is located below the cooling chamber 120. It can also be understood that the cooling chamber 120, the installation chamber 140 and the mechanical chamber 130 are all located below the storage chamber 110, and the installation chamber 140 is located below the cooling chamber 120, and the positions of the cooling chamber 120 and the installation chamber 140 in the box body 100 are staggered with the mechanical chamber 130 in the front-to-back direction, that is, the cooling chamber 120 and the installation chamber 140 are located on the same side in the front-to-back direction of the box body 100, and the mechanical chamber 130 is located on the other side in the front-to-back direction of the box body 100, or the cooling chamber 120 and the mechanical chamber 130 can also be arranged on the left and the right, and the installation chamber 140 is located below the same side of the cooling chamber 120 in the box body 100. In summary, it is necessary to ensure that one of the machine room 130 and the cooling room 120 is located at the front position and the other is located at the rear position, and the installation room 140 is located on the same side of the cooling room 120 in the machine room 130. By adjusting the position layout of the cooling room 120, the installation room 140 and the machine room 130, the space below the storage room 110 can be more effectively utilized. Generally, the volume of the compressor 400 is larger than the volume of the condenser 500 and the electric control box 600, which requires the refrigeration equipment 1000 to have a machine room 130 with a larger accommodation space to accommodate the compressor 400, and the space of the machine room 130 is larger than the space of the cooling room 120 and the installation room 140. In the related art, the compressor 400, the condenser 500 and the electric control box 600 are all installed in the machine room 130. However, when the refrigeration equipment 1000 is working, the compressor 400 and the condenser 500 will generate a lot of heat, which needs to be dissipated in time, but the space of the machine room 130 is limited, it is difficult to dissipate heat quickly, and it is easy to cause heat to accumulate in the machine room 130.In this embodiment, the compressor 400 is arranged in the machine room 130, the machine room 130 is located at the front side of the box 100, the evaporator 300 is arranged in the cooling room 120, the cooling room 120 is located at the rear side of the box 100, the evaporator 300 is used for the refrigeration device 1000 to exchange heat with the outside air, gasify and absorb heat, so that the device achieves a refrigeration effect, and at least one of the condenser 500 and the electric control box 600 is installed in the installation room 140, that is, the condenser 500 can be installed alone in the installation room 140. The electrical control box 600 may be installed alone in the installation room 140, or both the condenser 500 and the electrical control box 600 may be installed in the installation room 140. The installation of the condenser 500 and / or the electrical control box 600 in the installation room 140 can release a portion of the space in the mechanical room 130, so that the mechanical room 130 has more space for heat dissipation, accelerates the heat discharge of the refrigeration equipment 1000, and enhances the heat dissipation effect. In addition, the installation room 140 is set in the unused space below the storage room 110, so that the space utilization is more reasonable.

[0056] It should be emphasized that the refrigeration equipment 1000 of the present embodiment mainly adjusts the spatial distribution of the cooling chamber 120, the mechanical chamber 130 and the installation chamber 140, and arranges the evaporator 300 in the cooling chamber 120, and arranges the compressor 400 in the mechanical chamber 130, so as to fully utilize the space below the storage chamber 110, thereby improving the space utilization rate and improving the user experience. In addition, at least one of the condenser 500 and the electrical control box 600 is arranged in the installation chamber 140, and the compressor 400 is arranged in the mechanical chamber 130, so that at least one of the condenser 500 and the electrical control box 600 can be arranged separately from the compressor 400, which can reduce the heat dissipation interference between the condenser 500 or the electrical control box 600 and the compressor 400, which is beneficial to the heat dissipation of each, thereby improving the life and reliability of each system.

[0057] It should be noted that, in other embodiments, referring to Figure 6 As shown, the mechanical room 130 is located at the rear bottom of the box body 100, the cooling room 120 and the installation room 140 are located at the front side of the box body 100, and the installation room 140 is located below the cooling room 120, and the mechanical room 130, the cooling room 120 and the installation room 140 are all located below the storage room 110.

[0058] It should be noted that, refer to Figure 1 As shown, in some embodiments, the bottom plate in the box body 100 includes a first bottom plate 101 and a second bottom plate 102. The first bottom plate 101 is located on the rear side of the box body 100 and serves as the bottom wall of the installation chamber 140. The second bottom plate 102 is located on the front side of the box body 100 and serves as the bottom wall of the mechanical chamber 130. The first bottom plate 101 and the second bottom plate 102 are connected front to back. The first bottom plate 101 and the second bottom plate 102 can be detachably connected or fixedly connected.

[0059] It is understandable that in some embodiments of the present invention, reference Figure 1 As shown, the top wall of the installation room 140 is arranged to be tilted upward from the front to the back, and the condenser 500 is horizontally tilted and closely attached to the top wall of the installation room 140. The bottom wall of the installation room 140 is the first bottom plate 101 of the box body 100. Because the bottom plate of the box body 100 and the ground have a certain heat dissipation space, the condenser 500 arranged on the top wall of the installation room 140 can exchange heat with the air through the heat dissipation space. The condenser 500 can be laid on the top wall of the installation room 140 as much as possible to obtain a greater heat dissipation effect. In other embodiments, refer to Figure 3 As shown, the condenser 500 can also be arranged on the upper surface of the bottom wall of the installation chamber 140. In this way, the condenser 500 can be laid flat on the first bottom plate 101 of the box body 100, so that the condenser 500 can occupy as much of the bottom area of ​​the box body 100 as possible, increase the heat exchange area of ​​the installation chamber 140, and improve the heat dissipation efficiency; in other embodiments, a first condenser and a second condenser can be provided, the first condenser is arranged in the installation chamber 140, and the second condenser is arranged in the mechanical chamber 130. The volume of the second condenser is smaller than that of the first condenser. When the refrigeration equipment 1000 dissipates heat, the first condenser and the second condenser work together to exchange heat with the external hot air. This not only can make full use of the space under the storage chamber 110 of the box body 100, but also can reduce the heat dissipation burden in the mechanical chamber 130.

[0060] It is understandable that in some embodiments of the present invention, reference Figure 1 As shown, the box 100 is also provided with a partition structure, which is located above the front of the bottom plate. The partition structure includes a vertical section 105 and a horizontal section 106. The vertical section 105 extends vertically upward from the front edge of the first bottom plate 101 of the box 100, and the horizontal section 106 extends horizontally forward from the upper end of the vertical section 105. The horizontal section 106 is perpendicular to the vertical section 105, and the front end of the horizontal section 106 abuts against the door body 200. The front part of the vertical section 105 of the partition structure forms the rear wall of the machine room 130, and the lower part of the horizontal section 106 forms the top wall of the machine room 130. The partition structure can divide the box 100 into the machine room 130, so that the machine room 130 is relatively independent of the box 100, reducing the influence of the heat of the machine room 130 on the inside of the box 100. In other embodiments, refer to Figure 7 As shown, the vertical section 105 can be set to extend upward from the back to the front, and the horizontal section 106 extends horizontally forward from the upper end of the vertical section 105, and the length of the horizontal section 106 does not change. The space below the horizontal section 106 will increase slightly. It can also be understood that since the length of the vertical section 105 increases and the length of the horizontal section 106 remains unchanged, the space of the mechanical room 130 will increase.

[0061] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the machine room 130 is located in front of the cooling room 120. Specifically, the machine room 130 and the cooling room 120 are both located below the storage room 110, and the machine room 130 is located in front of the cooling room 120, that is, the machine room 130 is located in front of the box 100, and the cooling room 120 is located in the rear of the box 100. It can also be understood that the machine room 130 and the cooling room 120 are staggered in the box 100, one after the other, and the machine room 130 and the cooling room 120 are separated by a partition structure, the lower right side of the partition structure is the machine room 130, and the upper left side of the partition structure is the cooling room 120. The staggered separation arrangement of the machine room 130 and the cooling room 120 in the front-to-back direction can reduce the heat transfer of the compressor 400 in the machine room 130 to the cooling room 120 of the refrigeration device 1000, and the front placement of the machine room 130 is more conducive to the refrigeration device 1000 being embedded in the cabinet for use. When the refrigeration device 1000 is a built-in refrigerator, it is usually installed in a fixed groove inside a kitchen cabinet and coordinated with the cabinet. When the refrigeration device 1000 needs to be refrigerated, the compressor 400 starts to work, and the compressor 400 sucks in low-pressure refrigerant, compresses the refrigerant by driving the piston through the operation of the motor, and then discharges the high-temperature, high-pressure refrigerant to the condenser 500. The high-temperature, high-pressure refrigerant releases heat in the condenser 500. Since the mechanical room 130 is located at the front and lower part of the refrigeration device 1000, the mechanical room 130 can be away from the wall or cabinet, which can greatly reduce the heat dissipation effect of the wall or cabinet on the refrigeration device 1000. The heat generated by the refrigeration device 1000 during the refrigeration process can be directly discharged from the mechanical room 130 to the outside air, and heat exchange is performed with the air outside the refrigeration device 1000, thereby improving the heat dissipation efficiency of the refrigeration device 1000 and reducing the energy consumption of the refrigeration device 1000.

[0062] It is understandable that in some embodiments of the present invention, reference Figure 4 As shown, the electric control box 600 is disposed on the rear wall of the installation room 140, referring to Figure 5As shown, the electric control box 600 can also be arranged on the top wall of the installation room 140. Specifically, the electric control box 600 is the control center of the refrigeration equipment 1000, responsible for monitoring and controlling the temperature, humidity and other parameters of the storage room 110. The electric control box 600 contains various sensors and circuit boards. The electric control box 600 is connected to the compressor 400 and the condenser 500 and other components inside the refrigeration equipment 1000. The electric control box 600 can sense the temperature changes inside the refrigeration equipment 1000 and control the refrigeration of the storage room 110 according to the set temperature requirements. The electric control box 600 also has some other functions, such as controlling the lighting of the refrigeration equipment 1000, monitoring the switch status of the door body 200, etc. In the related art, the electrical control box 600 is usually arranged on the top of the refrigeration equipment 1000, or is arranged in the mechanical room 130. However, no matter whether the electrical control box 600 is arranged on the top of the refrigeration equipment 1000 or in the mechanical room 130, a part of space must be reserved for the installation of the electrical control box 600. The electrical control box 600 will occupy the space on the top of the refrigeration equipment 1000 or the space in the mechanical room 130, which makes it difficult to arrange other components. In addition, the electrical control box 600 is arranged in the mechanical room 130, and the compressor 400 located in the mechanical room 130 will generate a lot of heat when working. The control elements in the electrical control box 600 are prone to short circuit and explosion at high temperature, posing a safety hazard. In the embodiment of the utility model, the electric control box 600 can be installed on the rear wall or the top wall of the installation room 140. The rear wall or the top wall of the installation room 140 can be provided with an installation groove for the installation of the electric control box 600. There are many installation methods here, and the fixing can be achieved by welding, riveting, screw connection or snap-on structure. All of them can realize that the electric control box 600 is fixed in the installation groove of the installation room 140. The electric control box 600 is detachably installed in the installation groove. The electric control box 600 is detachably installed in the installation groove. It is convenient to take out the electric control box 600 from the installation room 140 of the refrigeration equipment 1000, and to adjust and repair the electric control box 600. Because the installation room 140 is arranged at the back of the refrigeration equipment 1000, the power supply of the refrigeration equipment 1000 is led out from the back and connected to the socket to supply power to the refrigeration equipment 1000. The electric control box 600 is arranged in the installation room 140 of the refrigeration equipment 1000, so that the power cord can be directly led out from the back of the refrigeration equipment 1000 and the line connection can be optimized. The wiring of the line is optimized.

[0063] It is understandable that in some embodiments of the present invention, reference Figure 1 and Fig. 9As shown, the condenser 500 can be located in the mechanical room 130, and the refrigeration equipment 1000 also includes a first fan 800, which is arranged in the mechanical room 130 and is used to dissipate heat for the compressor 400 and the condenser 500. Specifically, the compressor 400, the first fan 800 and the condenser 500 are arranged in the mechanical room 130 in sequence along the left-right direction. When working, the first fan 800 blows the air sucked from the direction of the condenser 500 to the compressor 400, and then discharges the heat to the outside of the mechanical room 130. The first fan 800 accelerates the air flow in the mechanical room 130 and can cool down the condenser 500. The air sucked from the direction of the condenser 500 is lower than the air of the compressor 400. The first fan 800 is arranged between the compressor 400 and the condenser 500, and the air outlet faces the compressor 400, which is beneficial to cooling the compressor 400 and improving the heat dissipation efficiency of the refrigeration equipment 1000. In other embodiments, refer to Fig.10 As shown, the first fan 800 is located on the right side of the condenser 500, that is, the first fan 800, the condenser 500 and the compressor 400 are arranged in sequence from right to left. The first fan 800 blows wind to the condenser 500 and the compressor 400 and helps the condenser 500 and the compressor 400 to dissipate heat, thereby changing the layout of the condenser 500, the first fan 800 and the compressor 400, and using suction and blowing to help the mechanical room 130 dissipate heat. The heat dissipation is simple to implement and can solve the ventilation and heat dissipation problems of the refrigeration equipment 1000.

[0064] It is understandable that in some embodiments of the present invention, reference Figure 1 and Fig. 9 As shown, the refrigeration device 1000 also includes an evaporating dish 700, which is used to store condensed water from the evaporator 300. The evaporating dish 700 is fixed to the bottom wall of the machine room 130. The first fan 800 and the condenser 500 are both arranged above the evaporating dish 700. The compressor 400 is located on the left side of the evaporating dish 700. The condensed water stored in the evaporating dish 700 can absorb part of the heat of the compressor 400 and the condenser 500 due to its low temperature. The heat of the compressor 400 and the condenser 500 can also evaporate the condensed water in the evaporating dish 700. The first fan 800 can also take away the water in the evaporating dish 700 for rapid heat dissipation. It should be noted that in other embodiments, referring to Fig.11 As shown, the compressor 400, the first fan 800, the evaporating dish 700 and the condenser 500 are sequentially arranged in the machine room 130 along the left-right direction in the cabinet 100. Compared with the first fan 800 and the condenser 500 being arranged in the evaporating dish 700, the evaporating dish 700 is independently arranged in the machine room 130, which can reduce the height of the machine room 130, thereby freeing up more space for the storage room 110 in the cabinet 100, so that the storage room 110 has a larger storage space.

[0065] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 8 As shown, the condenser 500 can be arranged in the installation room 140, and the installation room 140 is connected to the machine room 130. The refrigeration device 1000 also includes a first fan 800, which is arranged in the machine room 130 and is used to dissipate heat for the compressor 400 and the condenser 500. Specifically, the condenser 500 is arranged on the top wall of the installation room 140, and a windshield strip 141 is also arranged in the installation room 140. The windshield strip 141 is used to separate the installation room, so that the space size of the installation room 140 where the condenser 500 is installed is adapted to the heat dissipation capacity of the condenser 500 and the first fan 800, and the heat dissipation airflow from the installation room 140 to the machine room 130 is maintained at an appropriate flow rate, thereby enhancing the heat exchange capacity of the condenser 500, thereby improving the heat dissipation effect of the refrigeration device 1000. The front wall of the installation room 140 is connected to the mechanical room 130. The first fan 800 is arranged in the mechanical room 130. When working, the first fan 800 blows the air sucked from the direction of the condenser 500 to the surface of the compressor 400, and then discharges the heat to the outside through the heat dissipation port of the mechanical room 130. The heat dissipation port can be set at the bottom, left and right sides or the front side of the mechanical room. The first fan 800 accelerates the air flow in the mechanical room 130 and can cool down the condenser 500. This is because the heat dissipated by the compressor 400 is greater than the heat dissipated by the condenser 500. The compressor 400 is installed in the mechanical room 130, and the condenser 500 is installed in the installation room 140. That is, the temperature in the mechanical room 130 will be higher than the temperature in the installation room 140. The first fan 800 is set between the compressor 400 and the condenser 500, and the air outlet is facing the compressor 400. The lower temperature air in the installation room 140 will blow into the mechanical room 130, which is beneficial to cooling the compressor 400 in the mechanical room 130 and improving the heat dissipation efficiency of the refrigeration equipment 1000. It is understandable that the condenser 500 is installed in the installation room 140, and the compressor 400 is installed in the machine room 130. When heat dissipation is to be performed, air flows in the installation room 140 and the machine room 130. Compared with the case where both the condenser 500 and the compressor 400 are arranged in the machine room 130, the heat dissipation airflow can have a larger flow space, and the heat can be distributed in the installation room 140 and the machine room 130, rather than a large amount of heat being accumulated in the machine room 130. In other embodiments, referring to Figure 7As shown, the first fan 800 is located in the installation room 140. Since the condenser 500 and the first fan 800 are both installed in the installation room 140, the air outside the box 100 can be sucked into the box 100 through the installation room 140. The external air first exchanges heat with the condenser 500, and then enters the mechanical room 130 to exchange heat with the compressor 400 in the mechanical room 130. The first fan 800 can also be arranged between the installation room 140 and the mechanical room 130. This can optimize the spatial layout of the installation room 140 and the mechanical room 130, so that the installation room 140 and the mechanical room 130 can reduce the layout space occupied by components, so that there is more available space for heat dissipation, thereby improving the heat dissipation efficiency of the refrigeration equipment 1000.

[0066] It is understandable that in some embodiments of the present invention, reference Figure 1 and Fig.13 As shown, the cooling chamber 120 and the installation chamber 140 are staggered in the vertical direction, that is, the cooling chamber 120 and the installation chamber 140 are arranged on the left and right at different levels of the cabinet 100. In the first arrangement, the cooling chamber 120 is arranged on the left side of the cabinet 100, and the installation chamber 140 is arranged on the right side of the cabinet 100. In the second arrangement, the cooling chamber 120 is arranged on the right side of the cabinet 100, and the installation chamber 140 is arranged on the left side of the cabinet 100. Because the condenser 500 is installed on the installation chamber 140, In chamber 140, although there is insulation material between the cooling chamber 120 and the installation chamber 140, the heat of the condenser 500 in the installation chamber 140 during heat dissipation may still affect the cooling chamber 120, reducing the cooling effect of the evaporator 300. The cooling chamber 120 and the installation chamber 140 are staggered in the up and down directions, which extends the heat exchange path between the cooling chamber 120 and the installation chamber 140, and can reduce the impact of the installation chamber 140 on the cooling effect of the cooling chamber 120, thereby improving the cooling effect of the refrigeration equipment 1000.

[0067] It is understandable that in some embodiments of the present invention, reference Figure 1 and Fig. 9As shown, the condenser 500 is installed in the installation room 140, the electrical control box 600 is located in the mechanical room 130, and the electrical control box 600 and the compressor 400 are respectively located on both sides of the left and right directions of the box body 100. It can also be understood that when the electrical control box 600 is located on the left side of the mechanical room 130, the compressor 400 is located on the right side of the mechanical room 130, and when the electrical control box 600 is located on the right side of the mechanical room 130, the compressor 400 is located on the left side of the mechanical room 130. Because the trajectory of the heat dissipation airflow is from the installation room 140 to the mechanical room 130, in order to ensure that the heat dissipation airflow can flow through the condenser 500 and the compressor 400, the condenser 500 and the compressor 400 can be arranged in the installation room 140 and the mechanical room 130, and the electrical control box 600 is arranged in the mechanical room 130 on the side opposite to the compressor 400 in the left and right directions to reduce the obstruction of the heat dissipation airflow by the electrical control box 600.

[0068] It can be understood that in some embodiments, the condenser 500 is installed in the installation room 140, the electrical control box 600 and the compressor 400 are installed in the mechanical room 130, and the installation room 140 and the mechanical room 130 are connected. Compared with the situation where the condenser 500, the electrical control box 600 and the compressor 400 are all installed in the mechanical room 130, the condenser 500, the electrical control box 600 and the compressor 400 are arranged separately. This can reduce the heat dissipation effect between the condenser 500, the electrical control box 600 and the compressor 400, thereby enhancing the heat dissipation effect of the refrigeration equipment 1000. In other embodiments, the condenser 500 and the electrical control box 600 are both arranged in the installation room 140, and the compressor 400 is arranged in the mechanical room 130. Although the installation room 140 and the mechanical room 130 are connected, there is a certain distance between the installation room 140 and the mechanical room 130. The heat dissipation airflow first passes through the installation room 140 and then passes to the mechanical room 130. Compared with the situation where the condenser 500, the electrical control box 600 and the compressor 400 are all installed in the mechanical room 130, the heat dissipation space of the heat dissipation components can be increased and the heat dissipation influence between them can be reduced; in other embodiments, one or two of the condenser 500 and the electrical control box 600 are arranged in the installation room 140, and the compressor 400 is arranged in the mechanical room 130. The installation room 140 and the mechanical room 130 are isolated from each other and not connected, that is, the installation room 140 and the mechanical room 130 each perform heat dissipation, which can also reduce the heat transfer between the two chambers, reduce the heat influence between them, and improve the heat dissipation effect.

[0069] It is understandable that in some embodiments of the present invention, reference Fig.14As shown, the box body 100 includes a press cover plate 160, which extends in the up-down direction, and is detachably connected to the second bottom plate 102, and is configured as the front side wall of the machine room 130. The press cover plate 160 is provided with a first vent connected to the machine room 130, and the first vent can be understood as an air outlet heat dissipation vent or an air inlet heat dissipation vent. The machine room 130 can exchange heat with the outside of the refrigeration device 1000 through the first vent of the press cover plate 160, and the press cover plate 160 can also prevent debris from entering the machine room 130, and play a role in protecting the components in the machine room 130. The second bottom plate 102 may also be provided with a heat dissipation port, and the external air may enter the machine room 130 from the heat dissipation port of the second bottom plate 102, and then be discharged from the first vent of the press cover plate 160. A first recess 210 is provided on the side of the door body 200 close to the box body 100. The first recess 210 is located at the bottom of the door body 200. The position of the first recess 210 corresponds to the position of the first vent, and the first recess 210 is recessed toward the front. When the door body 200 is in a closed state, the door body 200 is relatively close to the box body 100, and the first recess 210 can reduce the distance from the door body 200 to the first vent. It can also be understood that a space is left at the first vent, which can be conducive to airflow, avoid the door body 200 blocking the first vent, and ensure smooth ventilation. It should be noted that, in some embodiments, there are multiple first vents, which can be arranged at the front, left or right side of the machine room 130, respectively. At least one first vent should be arranged to correspond to the first recess 210 of the door body 200 to ensure smooth ventilation. As for the shape of the first vent, the first vent can be strip-shaped, extending in the up-down direction, left-right direction or front-back direction, and can also be circular, square or arc-shaped.

[0070] It should be noted that, in other embodiments, referring to Fig.12 As shown, a partition 131 is provided in the mechanical room 130, the lower part of the partition 131 is perpendicular to the second bottom plate 102 and extends from bottom to top, the upper part of the partition 131 is in contact with the top wall of the mechanical room 130, and the partition 131 divides the space of the mechanical room 130 into an air inlet chamber 132 and an air outlet chamber 133, the air inlet chamber 132 is communicated with the installation room 140, and the compressor 400 is arranged in the air outlet chamber 133. When the mechanical room 130 is dissipating heat, the first fan 800 blows the hot air from the air inlet chamber 132 to the air outlet chamber 133 through the partition 131, so that the external air enters the mechanical room 130 from the air inlet chamber 132, and the heat of the mechanical room 130 is discharged to the outside of the refrigeration equipment 1000 through the air outlet chamber 133. The air inlet chamber 132 and the air outlet chamber 133 can reduce the back-suction phenomenon in the mechanical room 130, so that the heat can be quickly discharged to the outside of the mechanical room 130 along a predetermined path.

[0071] It is understood that in some embodiments, reference Fig.14 As shown, the door body 200 can be partially recessed to form the above-mentioned first recess 210, and the first recess 210 can be recessed into a trapezoidal, circular, arc-shaped or square shape, which can reduce the distance between the door body 200 and the vent 271 or leave a space for air flow. Fig.14 As shown, the first recess 210 may also extend in the left-right direction and penetrate the door body 200. Such a configuration may increase the clearance space reserved by the first recess 210. Even if the door body 200 is in a closed state, the airflow may flow in and out from the left side, right side or bottom side of the door body 200 along the first recess 210, thereby enhancing the fluidity of the airflow.

[0072] In some embodiments, the press cover 160 is detachably arranged. Since the press cover 160 is located at the front side of the machine room 130, after opening the door body 200, the machine room 130 can be maintained by removing the press cover 160, and the maintenance operation is relatively convenient.

[0073] It can be understood that in some embodiments of the present invention, the bottom wall or rear wall of the installation chamber 140 is provided with a second vent connected to the installation chamber 140, and the second vent is arranged on the bottom wall of the installation chamber 140, that is, the second vent is arranged on the first bottom plate 101 of the box body 100, and the second vent can serve as an air inlet. The air outside the box body 100 can enter the installation chamber 140 through the second vent by means of the bottom air inlet, and then exchange heat with the condenser 500 in the installation chamber 140, and dissipate heat for the compressor 400 in the mechanical room 130 under the action of the first fan 800. The above-mentioned bottom air inlet method is more conducive to the use of the embedded refrigeration device 1000. The embedded refrigeration device 1000 is usually installed in a fixed groove inside a kitchen cabinet and coordinated with the cabinet. However, since the heat dissipation space between the back and left and right sides of the embedded refrigeration device 1000 and the cabinet or wall is very small, some There is not even any space reserved for heat dissipation. The narrow space prevents the heat in the mechanical room 130 from being quickly discharged from the refrigeration device 1000. A large amount of heat accumulates in the mechanical room 130. As the refrigeration device 1000 continues to operate, the energy consumption and overall load of the refrigeration device 1000 will increase. The bottom air intake can reduce the influence of the cabinet or wall on the heat dissipation of the refrigeration device 1000, and facilitate the heat exchange between the refrigeration device 1000 and the external air. When the second vent is arranged on the rear wall of the installation room 140, that is, the second vent is arranged on the back plate 103 of the box body 100, it can also be understood that the refrigeration device 1000 adopts the method of back air intake and front air outlet. The external air is sucked into the installation room 140 from the back under the action of the first fan 800, and then reaches the mechanical room 130 to dissipate the heat of the condenser 500 and the compressor 400, and finally discharged to the outside of the refrigeration device 1000 through the first vent of the compressor cover plate 160. In other embodiments, multiple second vents can be provided, and the multiple second vents can be respectively arranged on the bottom wall or the rear wall of the installation chamber 140, that is, arranged on the first bottom plate 101 or the back plate 103 of the box body 100. The multiple second vents help to improve the ventilation efficiency of the refrigeration equipment 1000. At least one second vent should be arranged close to the condenser 500 in the installation chamber 140 to ensure the heat dissipation of the condenser 500.

[0074] It is understandable that in some embodiments of the present invention, reference Figure 1As shown, the refrigeration device 1000 also includes an air duct assembly and a second fan 900. The air duct assembly is provided with an air duct 150 connecting the cooling chamber 120 and the storage chamber 110. The air duct 150 is located on the inner wall of the back plate 103 of the refrigeration device 1000 and extends vertically upward. The bottom of the air duct 150 is connected to the cooling chamber 120. An air outlet 151 is provided above the air duct 150 so that the air flow cooled by the evaporator 300 enters the storage chamber 110 through the air outlet 151 of the air duct 150. A second fan 900 is provided in the air duct 150. The second fan 900 is vertically arranged in the air duct 150. The second fan 900 is located on the side of the evaporator 300 away from the mechanical chamber 130, and the position of the second fan 900 is higher than that of the evaporator 300. It should be noted that the air duct 150 is located on the back plate 103 of the refrigeration device 1000 and is connected to the cooling chamber 120. The evaporator 300 cools the nearby air. The density of the cooled air is greater than that of the hot air, and the cooled air will sink and accumulate at the bottom of the cooling chamber 120. The second fan 900 located above the evaporator 300 can draw the sinking cold air into the air supply channel. The cold air is transported from back to front to the storage chamber through the air outlet 151 of the air supply channel. When the evaporator 300 is working, the evaporator 300 absorbs the heat in the refrigeration device 1000 to reduce the temperature in the refrigeration device 1000. The second fan 900 delivers the cold air generated by the evaporator 300 into the air duct 150, and then evenly distributes the cold air to all corners of the refrigeration device 1000 through the air outlet 151 above the air duct 150, thereby ensuring that the temperature in the refrigeration device 1000 is balanced. In other embodiments, refer to Figure 3 As shown, the second fan 900 can be arranged to be tilted forward behind the evaporator 300 so that the air outlet of the second fan 900 faces the air duct 150, and the cold air generated by the evaporator 300 can easily enter the air duct 150.

[0075] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
