Description

Technical Field

[0001] This application relates to the technical field of vending, and particularly to a retail device. Background Art

[0002] With the continuous development of digital technology and the sharing economy, retail cabinets have become increasingly popular. The main function of existing retail cabinets is to provide customers with food in a refrigerated or normal temperature state, and a refrigeration system is installed inside the cabinet for refrigeration. However, if the retail cabinet is placed in an environment with a temperature lower than the adjustable temperature range inside the cabinet, such as an outdoor place like a park in winter, it will affect the taste of the food inside the cabinet and even pose safety hazards such as freezing and bursting the food.

[0003] To avoid this problem, operators generally remove the food inside the retail cabinet in winter and then turn off and deactivate the retail cabinet, resulting in the inability to provide services to customers. Summary of the Utility Model

[0004] In view of this, this application proposes a retail device that can be used normally even when placed outdoors in winter, so that it is not necessary to remove the goods inside the retail device in winter, that is, it is not necessary to turn off and deactivate the retail device in winter, thus being able to better provide services to customers.

[0005] This application proposes a retail device, including:

[0006] A cabinet;

[0007] A refrigeration system, including a compressor, a condenser, a throttling mechanism, and an evaporator. The compressor is used to compress the refrigerant gas and deliver the compressed refrigerant gas to the condenser. After the refrigerant gas condenses into a liquid refrigerant in the condenser, it passes through the throttling mechanism to throttle and depressurize into a low-pressure liquid refrigerant and is delivered to the evaporator. The evaporator is arranged inside the cabinet, and the liquid refrigerant absorbs heat and vaporizes in the evaporator to absorb the air heat inside the cabinet;

[0008] A first fan, arranged inside the cabinet and close to the evaporator;

[0009] A heating device, arranged between the first fan and the evaporator, and the heating device is used to heat the air inside the cabinet;

[0010] Wherein, when the refrigeration system is working, the first fan is used to accelerate the flow of cold air to lower the temperature inside the cabinet, and when the heating device is working, the first fan is used to accelerate the flow of hot air to raise the temperature inside the cabinet.

[0011] As can be seen from the above technical solution, the retail device proposed in this application includes a cabinet body, a refrigeration system, a first fan, and a heating device. When it is necessary to lower the temperature inside the cabinet, refrigeration can be carried out through the refrigeration system, and when it is necessary to raise the temperature inside the cabinet, heating can be carried out through the heating device. As a result, the retail device can be used normally even when placed outdoors in winter, so there is no need to take out the goods inside the retail device in winter, that is, there is no need to shut down and stop using the retail device in winter, thus enabling better service for customers. At the same time, the heating device is arranged between the first fan and the evaporator, and the first fan is used to accelerate the flow of cold air or hot air, which not only improves the efficiency of temperature adjustment, but also has a compact structure and saves costs.

[0025] Refer to Figures 1 to 5, an embodiment of the present application provides a retail device 100, including a cabinet 10, a refrigeration system 20, a first fan 30, and a heating device 40. The refrigeration system 20 includes a compressor 21, a condenser 22, an evaporator 23, and a throttling mechanism 24. The compressor 21 is used to compress the refrigerant gas and deliver the compressed refrigerant gas to the condenser 22. After the refrigerant gas condenses into a liquid refrigerant in the condenser 22, it is throttled and depressurized by the throttling mechanism 24 to become a low-pressure liquid refrigerant and is delivered to the evaporator 23. The evaporator 23 is disposed inside the cabinet 10, and the liquid refrigerant absorbs heat and vaporizes in the evaporator 23 to absorb the heat of the air inside the cabinet 10. The first fan 30 is disposed inside the cabinet 10 and close to the evaporator 23. The heating device 40 is disposed between the first fan 30 and the evaporator 23, and the heating device 40 is used to heat the air inside the cabinet 10. Wherein, when the refrigeration system 20 operates, the first fan 30 is used to accelerate the flow of cold air to reduce the temperature inside the cabinet 10. When the heating device 40 operates, the first fan 30 is used to accelerate the flow of hot air to increase the temperature inside the cabinet 10.

[0026] The retail device 100 provided by the embodiment of the present application includes a cabinet 10, a refrigeration system 20, a first fan 30, and a heating device 40. When it is necessary to reduce the temperature inside the cabinet 10, refrigeration can be performed through the refrigeration system 20. When it is necessary to increase the temperature inside the cabinet 10, heating can be performed through the heating device 40. Thus, the retail device 100 can be used normally even when placed outdoors in winter, so that it is not necessary to take out the commodities inside the retail device 100 in winter, that is, it is not necessary to shut down and stop using the retail device 100 in winter, and thus better services can be provided for customers. At the same time, the heating device 40 is disposed between the first fan 30 and the evaporator 23. By accelerating the flow of cold air or hot air through the first fan 30, not only the efficiency of temperature adjustment can be improved, but also the structure is compact and the cost is saved.

[0027] Refer to Figures 1 to 4 , in some embodiments, a sealed accommodation space 11 is provided inside the cabinet 10. The evaporator 23, the first fan 30, and the heating device 40 are disposed inside the accommodation space 11. The compressor 21 and the condenser 22 are disposed outside the accommodation space 11, and the compressor 21 is communicated with the condenser 22. The condenser 22 is communicated with the evaporator 23 inside the accommodation space 11 through the throttling mechanism 24. Wherein, the accommodation space 11 can be used to place commodities to be sold, and the commodities can be beverages, foods, etc. Thus, disposing the evaporator 23, the first fan 30, and the heating device 40 inside the accommodation space 11 is conducive to absorbing the heat of the air inside the accommodation space 11 or heating the air inside the accommodation space 11 to meet the temperature requirements for commodity storage. And placing the compressor 21 and the condenser 22 outside the accommodation space 11 can prevent the heat they emit from entering the accommodation space 11.

[0028] Exemplarily, when the refrigeration system 20 operates, the compressor 21 starts (it can be driven by electricity to make the piston reciprocate, or it can be started in other ways. The type of the compressor 21 is not limited here). It sucks in the low-pressure refrigerant vapor, and after being compressed, it forms a high-temperature and high-pressure refrigerant gas, which can be transported to the condenser 22 through the exhaust pipe. The refrigerant gas releases heat in the condenser 22 and is gradually cooled and condensed into a high-pressure liquid refrigerant. Then, it passes through the throttling mechanism 24 to reduce the pressure and become a low-pressure liquid refrigerant. The low-pressure liquid refrigerant is transported to the evaporator 23, where the liquid refrigerant absorbs heat and vaporizes to absorb the heat of the air in the accommodation space 11. At this time, the first fan 30 is used to accelerate the flow of cold air to reduce the temperature in the accommodation space 11.

[0029] Specifically, the refrigerant gas coming out of the evaporator 23 can be sucked back into the compressor 21 through the return pipe to form a refrigeration cycle.

[0030] In some embodiments, a dryer filter can also be provided outside the accommodation space 11. The refrigerant gas condensed into a high-pressure liquid refrigerant in the condenser 22 can pass through the dryer filter, so that the moisture and impurities in the liquid refrigerant are dried and filtered to prevent clogging of the throttling mechanism 24. Then, the filtered liquid refrigerant is transported to the evaporator 23 through the throttling mechanism 24.

[0031] In some embodiments, the throttling mechanism 24 for transporting the liquid refrigerant to the evaporator 23 can be a capillary tube, or other throttling mechanisms that can achieve the same function. The refrigerant is throttled in the capillary tube, and at the same time, the pressure gradually decreases. At the end of the capillary tube, the refrigerant is mainly in a liquid state, and at the same time, it is mixed with a part of the released gas. The end of the capillary tube is connected to the evaporator 23.

[0032] In some application scenarios, the compressor 21, the exhaust pipe, the condenser 22, and the dryer filter are placed outside the accommodation space 11 and well thermally insulated, so as to avoid the heat dissipated from entering the accommodation space 11. Among them, the two ends of the capillary tube are respectively connected to the dryer filter and the compressor 21, and the two ends of the return pipe are respectively connected to the evaporator 23 and the compressor 21. Therefore, the capillary tube and the return pipe need to pass through the accommodation space 11 and are also well thermally insulated.

[0033] It should be noted that the outside of the accommodation space 11 can be the space outside the cabinet 10, or another space separated from the accommodation space 11 inside the cabinet 10.

[0034] In some embodiments, the heating device 40 includes a PTC heating device 40 (Positive Temperature Coefficient, abbreviated as PTC). The PTC heating device 40 has an automatic constant temperature function. When the temperature reaches the set value, the resistance of the PTC element increases sharply, the current decreases rapidly, thereby stopping heating and cutting off the power supply, preventing overheating and fire, and improving safety performance. In addition, the PTC heater can not only quickly generate high temperature after being powered on to achieve rapid heating, but also maintain a constant temperature effect for a certain period of time with its residual heat after being powered off, so energy can be saved.

[0035] Of course, in other embodiments, the heating device 40 can also be other heaters as long as they can achieve the heating effect.

[0036] Refer to Figures 1 to 2 , in some embodiments, the cabinet 10 includes a top wall 10a, a bottom wall 10b, and a plurality of side walls 10c that enclose to form a receiving space 11. The evaporator 23, the heating device 40, and the first fan 30 are all installed on the top wall 10a and close to one of the side walls 10c. The cabinet 10 further includes an installation space 12. The installation space 12 and the receiving space 11 are separated by the bottom wall 10b. The compressor 21 and the condenser 22 are arranged in the installation space 12. By separating the receiving space 11 from the installation space 12 with the bottom wall 10b, the structure is compact. Installing the compressor 21 and the condenser 22 in the lower installation space 12 enables the upper space of the cabinet 10 to be more effectively utilized to place goods. At the same time, placing the compressor 21 and the condenser 22 in the installation space 12 can reduce noise to a certain extent.

[0037] Among them, installing the evaporator 23, the heating device 40, and the first fan 30 in the upper part of the receiving space 11 and close to the corner of the side wall 10c has a relatively compact layout and high space utilization rate, enabling sufficient space in the receiving space 11 to place goods. In addition, it is also beneficial for the cooled or heated air to be quickly dispersed throughout the receiving space 11 through the first fan 30 to meet the temperature requirements for storing goods.

[0038] In some embodiments, the cabinet 10 can be provided with a first door on the side wall 10c of the receiving space 11 so that the receiving space 11 can be opened or closed through the first door. Thus, when goods need to be stocked, the receiving space 11 can be opened through the first door to place goods at the corresponding position in the receiving space 11. Of course, when it is necessary to repair the components in the receiving space 11 or for other needs, the receiving space 11 can also be opened through the first door, thus facilitating the use of the retail device 100.

[0039] In some embodiments, the cabinet body 10 may be provided with a second door on the side wall 10c of the installation space 12, so that the installation space 12 can be opened or closed through the second door. Thus, when it is necessary to repair the components in the installation space 12 or in other cases where there is a need, the installation space 12 can be opened through the second door, thereby facilitating the use of the retail device 100.

[0040] Referring to Figures 1 to 2 , in some embodiments, the first fan 30 has an air inlet 31 and an air outlet 32. The heating device 40 is close to the air outlet 32, and the first fan 30 is arranged obliquely downward from the air outlet 32 towards the air inlet 31. Thus, the air outlet 32 of the first fan 30 faces the heating device 40, which can improve the heating efficiency when heating is required. In addition, setting the first fan 30 obliquely downward can better guide the air flow and form an air flow cycle, so that cold air or hot air can be evenly distributed to each corner of the accommodation space 11, improving the temperature adjustment efficiency.

[0041] Of course, in other embodiments, each component may also be arranged in other ways, and after installation, each component can cooperate to work to achieve heating or refrigeration, so as to adjust the temperature in the accommodation space 11 according to the temperature required by the commodity.

[0042] Referring to Figures 3 to 5 , in some embodiments, the retail device 100 further includes a main control board 50. The main control board 50 is arranged in the installation space 12, and the heating device 40, the first fan 30, and the compressor 21 are all electrically connected to the main control board 50. Thus, the setting of the main control board 50 facilitates the control of the operation of each component.

[0043] In some embodiments, the main control board 50 may be arranged on the side of the condenser 22 away from the compressor 21, with a compact layout. Of course, in other embodiments, the main control board 50 may also be arranged in other positions, as long as it can be electrically connected to other components to control the operation of other components.

[0044] In some embodiments, the side wall 10c and the bottom wall 10b are provided with a wiring channel, and the connecting wire of the heating device 40 is connected to the main control board 50 located in the installation space 12 through the wiring channel. Through the setting of the wiring channel, the wiring of the connecting wire can be facilitated, thereby preventing the connecting wire of the heating device 40 from being exposed and affecting the appearance.

[0045] In some embodiments, the top wall 10a, the bottom wall 10b, and the plurality of side walls 10c that enclose the accommodation space 11 may be provided with a heat insulation layer. The heat insulation layer may adopt foaming materials such as polyurethane foam to form a thermally insulated enclosed space and achieve the heat insulation effect. Among them, the wiring channel may be arranged in the heat insulation layer, and the connecting wire of the heating device 40 is connected to the main control board 50 through the inside of the heat insulation layer, thereby preventing exposure and affecting the appearance.

[0046] In some embodiments, the retail device 100 further includes a temperature sensor 60 disposed within the cabinet 10. The temperature sensor 60 is configured to detect the temperature within the cabinet 10 and send a signal to the main control board 50, and the main control board 50 is configured to control the operating states of the refrigeration system 20 and the heating device 40 based on the temperature detected by the temperature sensor 60. Thus, by providing the temperature sensor 60, the temperature of the accommodation space 11 within the cabinet 10 can be monitored, and the temperature change can be promptly fed back to the main control board 50. The main control board 50 can adjust the temperature within the accommodation space 11 according to the temperature required for the goods, thereby avoiding adverse effects on the goods due to inappropriate temperature.

[0047] In some embodiments, the temperature sensor 60 is configured to send a first signal to the main control board 50 when the temperature within the cabinet 10 is detected to be higher than a first preset temperature, and the temperature sensor 60 is further configured to send a second signal to the main control board 50 when the temperature within the cabinet 10 is detected to drop to a second preset temperature, and the temperature sensor 60 is further configured to send a third signal to the main control board 50 when the temperature within the cabinet 10 is detected to be lower than a third preset temperature, and the temperature sensor 60 is further configured to send a fourth signal to the main control board 50 when the temperature within the cabinet 10 is detected to be higher than a fourth preset temperature. The main control board 50 is configured to control the refrigeration system 20 to operate when receiving the first signal, and the main control board 50 is further configured to control the refrigeration system 20 to stop operating when receiving the second signal, and the main control board 50 is further configured to control the heating device 40 to operate when receiving the third signal, and the main control board 50 is further configured to control the heating device 40 to stop operating when receiving the fourth signal. Herein, the first preset temperature is greater than or equal to the fourth preset temperature, and the second preset temperature is greater than or equal to the third preset temperature. Thus, through the different signals sent by the temperature sensor 60, different operating states of the refrigeration system 20 and the heating device 40 are triggered to control the main control board 50, so that the temperature within the accommodation space 11 can be precisely controlled to meet the temperature required for storing the goods and avoid adverse effects on the goods due to inappropriate temperature.

[0048] In some embodiments, the temperature within the accommodation space 11 of the cabinet 10 can be set according to the temperature required for the goods. For example, if the temperature within the accommodation space 11 of the cabinet 10 is set to N °C, then the first preset temperature is N + a °C, the second preset temperature is N - b °C, the third preset temperature is N - c °C, and the fourth preset temperature is N + d °C. Herein, a > d and c > b.

[0049] In some application scenarios, when the temperature sensor 60 detects that the temperature in the accommodation space 11 is higher than N + a °C, the main control board 50 controls the refrigeration system 20 to operate. At this time, the compressor 21, the condenser 22, the evaporator 23, and the first fan 30 cooperate to achieve refrigeration to reduce the temperature. When the temperature sensor 60 detects that the temperature in the accommodation space 11 drops to N - b °C, the main control board 50 controls the refrigeration system 20 to stop operating to reduce power consumption. When the temperature sensor 60 detects that the temperature in the accommodation space 11 is lower than N - c °C, the main control board 50 controls the heating device 40 to operate. At this time, the heating device 40 and the first fan 30 cooperate to achieve heating to raise the temperature. When the temperature sensor 60 detects that the temperature in the accommodation space 11 is higher than N + d °C, the main control board 50 controls the heating device 40 to stop operating to reduce power consumption.

[0050] In some embodiments, N can be 1 °C - 15 °C, and a, b, c, and d can be 0 °C - 10 °C. Exemplarily, N can be equal to 5 °C, a can be equal to 2 °C, b can be equal to 1 °C, c can be equal to 2 °C, and d can be equal to 1 °C. That is, the first preset temperature is 7 °C, the second preset temperature is 4 °C, the third preset temperature is 3 °C, and the fourth preset temperature is 6 °C. Of course, in other examples, according to the different temperatures required for different commodities, a, b, c, and d can also be other values, as long as a > d and c > b are satisfied.

[0051] In some usage scenarios, for example, in winter, when the outdoor temperature gradually drops to 0 °C or even below 0 °C, the temperature in the accommodation space 11 will also gradually decrease due to the influence of the outdoor temperature. When the temperature sensor 60 detects that the temperature in the accommodation space 11 drops to the second preset temperature, that is, 4 °C, the main control board 50 controls the refrigeration system 20 to stop operating to reduce power consumption. When the temperature sensor 60 detects that the temperature in the accommodation space 11 drops to the third preset temperature, that is, 3 °C, the main control board 50 controls the heating device 40 to operate. At this time, the heating device 40 and the first fan 30 cooperate to achieve heating to raise the temperature, so as to prevent the commodities in the accommodation space 11 from being frozen and affecting sales. After the heating device 40 operates, when the temperature sensor 60 detects that the temperature in the accommodation space 11 is higher than the fourth preset temperature, that is, 6 °C, the main control board 50 controls the heating device 40 to stop operating to reduce power consumption, so that the temperature of the accommodation space 11 is maintained at the temperature required for storing the commodities.

[0052] In some usage scenarios, for example, in summer, the outdoor temperature may be in the range of 25°C - 30°C or even higher. At this time, the temperature in the accommodation space 11 will also gradually rise under the influence of the outdoor temperature. When the temperature sensor 60 detects that the temperature in the accommodation space 11 is higher than the first preset temperature, that is, 7°C, the main control board 50 controls the refrigeration system 20 to operate. At this time, the compressor 21, the condenser 22, the evaporator 23, and the first fan 30 cooperate to achieve refrigeration to reduce the temperature. When the temperature sensor 60 detects that the temperature in the accommodation space 11 drops to the second preset temperature, that is, 4°C, the main control board 50 controls the refrigeration system 20 to stop working to reduce power consumption, so that the temperature of the accommodation space 11 is maintained at the temperature required for storing goods.

[0053] Referring to Figure 2 , in some embodiments, the retail device 100 further includes an air duct structure 70 having a first air outlet 71 and a second air outlet 72. The first air outlet 71 is communicated with the air outlet 32 of the first fan 30, and the second air outlet 72 is close to the bottom of the accommodation space 11, so that the air flow blown out from the air outlet 32 of the first fan 30 enters the air duct structure 70 through the first air outlet 71, then blows out from the second air outlet 72, and is sucked into the air inlet 31 of the first fan 30 after passing through the accommodation space 11 from bottom to top. Thus, through the setting of the air duct structure 70, its second air outlet 72 is close to the bottom of the accommodation space 11, so that the air blown out by the first fan 30 blows out from the second air outlet 72 at the bottom through the air duct structure 70, and then evenly passes through the goods in the accommodation space 11 from bottom to top and is then sucked back into the first fan 30, thereby making the temperature of the accommodation space 11 in the cabinet 10 uniform and facilitating the storage of goods in a suitable temperature environment.

[0054] In some embodiments, the air duct structure 70 may be an air duct plate provided below the air outlet 32. Through the setting of the air duct plate, it is convenient to guide the air blown out by the first fan 30 to blow out from the second air outlet 72 at the bottom.

[0055] Referring to Figures 1 to 3, in some embodiments, when the liquid refrigerant absorbs heat and vaporizes in the evaporator 23, water vapor in the air may form condensate on the surface of the evaporator 23. The refrigeration system 20 further includes a water receiving assembly 80. The water receiving assembly 80 includes a first water receiving container 81, a water outlet pipe 82, and a second water receiving container 83. The first water receiving container 81 is disposed at the bottom of the evaporator 23, the second water receiving container 83 is disposed on the compressor 21, and the water outlet pipe 82 connects the first water receiving container 81 and the second water receiving container 83. In the case where condensate forms on the surface of the evaporator 23, the condensate flows into the first water receiving container 81 and then flows into the second water receiving container 83 through the water outlet pipe 82. In the case where the condensate flows into the second water receiving container 83, the heat generated by the operation of the compressor 21 is used to evaporate the condensate. Thus, the heat of the compressor 21 can be utilized to evaporate the condensate, so as to prevent the condensate from falling and affecting the use of other components.

[0056] Refer to Figures 3 to 4 , in some embodiments, the retail device 100 further includes a second fan 90. The second fan 90 is electrically connected to the main control board 50 and is close to the condenser 22 for dissipating heat from the condenser 22. Thus, through the arrangement of the second fan 90, heat dissipation of the condenser 22 can be facilitated, thereby improving the refrigeration efficiency.

[0057] In some embodiments, the second fan 90 can be disposed on the side of the condenser 22 close to the compressor 21. This not only makes the structure compact, but also the second fan 90 can play a certain role in evaporating the condensate.

[0058] Refer to Figures 1 to 3 , in some embodiments, the retail device 100 further includes a wall stop 110. The wall stop 110 is installed on the outer wall of the cabinet 10. Through the arrangement of the wall stop 110, it is prevented that the air intake space of the condenser 22 is too small, which affects the heat dissipation of the condenser 22.

[0059] Refer to Figures 1 to 4 , in some embodiments, the retail device 100 further includes a support member 120. The support member 120 is disposed at the bottom of the cabinet 10 to support the cabinet 10 on the surface to be supported. Exemplarily, the surface to be supported can be the floor. Multiple support members 120 can be provided, such as four or more. The multiple support members 120 evenly support the bottom of the cabinet 10 to disperse the force. Thus, through the support of the support member 120, it can be ensured that the retail device 100 can still remain stable when carrying a large number of goods.

[0060] In some embodiments, the support member 120 is configured to be height-adjustable, so that the height of each support member 120 can be adjusted according to the floor condition to prevent the retail device 100 from being unbalanced due to uneven floor.

[0061] Subject to no contradiction, those skilled in the art may combine and integrate the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0062] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily conceive of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
