The condensation coil is used to receive the refrigerant output by the compressor and make the refrigerant exchange heat with the gas in the condenser. The evaporation coil is used to receive the refrigerant output by the condensation coil and make the refrigerant exchange heat with the gas in the evaporator.

[0007] In some embodiments, the drying device further includes an expansion valve, which is disposed at one end of the condensation coil connecting to the evaporation coil. The expansion valve is configured to decompress the refrigerant output from the condensation coil and transmit the decompressed refrigerant to the evaporation coil.

Thus, the evaporator outputs dry gas to the heating mechanism. The heating mechanism receives and heats the gas output by the evaporator, and heats the received gas to a preset temperature and outputs it to the working chamber, so that the gas entering the working chamber dries the product. Since the range of the preset temperature is 60°C - 90°C, compared with an oven with an internal temperature of about 120°C, the temperature of the gas entering the working chamber in the embodiment of the present application is lower, so the energy consumption is lower, and the gas at the preset temperature is not likely to damage the surface characteristics and quality of the product.

[0060] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0061] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a drying device 100 for drying products.

[0062] In this embodiment, the drying device 100 includes a working box 10, a suction mechanism 20, an evaporator 30, and a heating mechanism 40.

[0063] The working box 10 is used to accommodate the product, the suction mechanism 20 is connected to the working box 10, the evaporator 30 is connected to the suction mechanism 20, the suction mechanism 20 is used to extract the gas in the working box 10 and output it to the evaporator 30, the evaporator 30 is used to condense and dry the gas output by the suction mechanism 20, the heating mechanism 40 is respectively connected to the evaporator 30 and the working box 10, the heating mechanism 40 is used to receive and heat the gas output by the evaporator 30, and is used to heat the received gas to a preset temperature and output it to the working box 10, so that the gas entering the working box 10 dries the product, and the preset temperature ranges from 60 degrees to 90 degrees. It can be understood that the temperature here refers to Celsius. In this embodiment, the preset temperature is 80 degrees. It can be understood that in other embodiments, the preset temperature can also be 60 degrees, 70 degrees or 90 degrees.

[0064] When using the above-mentioned drying equipment 100 to remove moisture from the surface of the product, the product is placed in the working box 10, and the suction mechanism 20 extracts the gas in the working box 10 and outputs it to the evaporator 30. The evaporator 30 is used to condense and dry the gas output by the suction mechanism 20 so that the moisture in the gas forms condensed water, so that the evaporator 30 outputs dry gas to the heating mechanism 40. The heating mechanism 40 receives and heats the gas output by the evaporator 30, and heats the received gas to a preset temperature and outputs it to the working box 10, so that the gas entering the working box 10 dries the product. Since the preset temperature ranges from 60 degrees to 90 degrees, compared with an oven with an internal temperature of about 120 degrees, the temperature of the gas entering the working box 10 in the embodiment of the present application is lower, thereby lowering energy consumption, and the gas at the preset temperature is not easy to damage the surface characteristics and quality of the product. In addition, driven by the suction mechanism 20, the gas circulates between the working box 10, the suction mechanism 20, the evaporator 30 and the heating mechanism 40, so that the gas of preset temperature flowing in the working box 10 blows the product to achieve drying of the product.

[0065] In this embodiment, the suction mechanism 20 includes an air outlet pipe 21, a fan 22 and a guide assembly 23. The air outlet pipe 21 is connected to the working box 10, and the fan 22 is connected to one end of the working box 10 away from the air outlet pipe 21. The fan 22 is used to suck the gas in the working box 10 through the air outlet pipe 21. The guide assembly 23 is respectively connected to the fan 22 and the evaporator 30. The guide assembly 23 is used to receive the gas output by the fan 22 and guide the gas to be transmitted to the evaporator 30. Specifically, the setting of the guide assembly 23 facilitates the guidance of the transmission of the gas and ensures that the gas is transmitted to the required area. In this embodiment, the guide assembly 23 is surrounded by a plurality of plate-like structures to form a guide channel so that the gas is transmitted to the evaporator 30 along the guide channel.

[0066] In this embodiment, the heating mechanism 40 includes a condenser 41 and an auxiliary heater 42. The condenser 41 is connected to the evaporator 30. The condenser 41 is used to receive and heat the gas output by the evaporator 30. The auxiliary heater 42 is connected to the condenser 41. The auxiliary heater 42 is used to receive and heat the gas heated by the condenser 41, so as to heat the received gas to a preset temperature and output it to the working chamber 10. Specifically, when the condenser 41 operates, it releases heat to the gas inside the condenser 41, so that the temperature of the gas inside the condenser increases. The auxiliary heater 42 further heats the gas to the preset temperature.

[0067] In this embodiment, the auxiliary heater 42 includes a heating element 421 and an air supply duct 422. The heating element 421 is arranged inside the air supply duct 422. One end of the air supply duct 422 is connected to the condenser 41, and the other end of the air supply duct 422 is connected to the working chamber 10. Specifically, after the gas is output from the condenser 41, its temperature may not reach the required preset temperature. By arranging the heating element 421, it is convenient to heat the gas to the required preset temperature, and then transport it to the working chamber 10 through the air supply duct 422, so that the gas at the preset temperature can dry the products in the working chamber 10. In this embodiment, the heating element 421 is a heating rod. It can be understood that in other embodiments, the heating element 421 can be other heating structures capable of heating the gas to the preset temperature. Here, the detection of the gas temperature and the control of the operation of each component according to the detected preset temperature can be obtained by those skilled in the art from other documents, and will not be elaborated here.

[0068] In this embodiment, the heating mechanism 40 further includes a preheater 43. The preheater 43 is respectively connected to the condenser 41 and the evaporator 30. The condenser 41 and the evaporator 30 are connected through the preheater 43. The preheater 43 is used to receive and preheat the gas output by the evaporator 30, and is also used to preheat the received gas and output it to the condenser 41. Specifically, the gas is preheated by the preheater 43 first, and then heated by the condenser 41, so as to prevent the temperature of the gas output by the evaporator 30 from being too low and unable to reach the required temperature when directly heated by the condenser 41.

[0069] Please refer to Figure 3, in this embodiment, the drying device 100 further includes a compressor 50. The evaporator 30 is provided with an evaporation coil 31, and the condenser 41 is provided with a condensation coil 411. The evaporation coil 31, the compressor 50, and the condensation coil 411 are connected end to end in sequence to form a loop. The compressor 50 contains a refrigerant. The compressor 50 is used to drive the refrigerant to circulate between the compressor 50, the condensation coil 411, and the evaporation coil 31. The condensation coil 411 is used to receive the refrigerant output by the compressor 50 and exchange heat between the refrigerant and the gas in the condenser 41. The evaporation coil 31 is used to receive the refrigerant output by the condensation coil 411 and exchange heat between the refrigerant and the gas in the evaporator 30. Specifically, the refrigerant exchanges heat with the gas twice. The suction mechanism 20 extracts the gas in the working chamber 10 and outputs it to the evaporator 30. The temperature of the gas in the evaporator 30 is relatively high. When the refrigerant in the evaporation coil 31 of the evaporator 30 exchanges heat with the gas in the evaporator 30, the refrigerant evaporates and absorbs heat in the evaporation coil 31, so as to cool and dry the gas in the evaporator 30, and condense the water vapor in the gas to form condensed water and discharge it from the evaporator 30. The refrigerant in the evaporation coil 31 is compressed by the compressor 50 to form a high-pressure steam with a higher temperature and enters the condensation coil 411 of the condenser 41. When the refrigerant in the condensation coil 411 exchanges heat with the gas in the condenser 41, the refrigerant liquefies and releases heat in the condensation coil 411, so as to increase the temperature of the gas in the condenser 41, and output the drier air with a higher temperature to the auxiliary heater 42. Among them, the refrigerant evaporates and absorbs heat in the evaporation coil 31 of the evaporator 30, causing the temperature of the refrigerant to rise; the refrigerant liquefies and releases heat in the condensation coil 411 of the condenser 41, causing the temperature of the refrigerant to drop.

[0070] In this embodiment, the drying device 100 further includes an expansion valve 60. The expansion valve 60 is arranged at one end where the condensation coil 411 is connected to the evaporation coil 31. The expansion valve 60 is used to decompress the refrigerant output by the condensation coil 411 and transmit the decompressed refrigerant to the evaporation coil 31. After the refrigerant liquefies and releases heat in the condenser 41, it is decompressed by the expansion valve 60 and then returns to the evaporator 30. Among them, after the refrigerant output by the condensation coil 411 is decompressed by the expansion valve 60, the pressure and temperature of the refrigerant decrease.

[0071] In this embodiment, the drying device 100 further includes a filter element 70. The filter element 70 is arranged between the suction mechanism 20 and the evaporator 30. The filter element 70 is used to filter the gas output by the suction mechanism 20. The gas output by the suction mechanism 20 is filtered by the filter element 70 and then output to the evaporator 30. The setting of the filter element 70 facilitates filtering the impurities in the gas to ensure the quality of the circulating gas. In this embodiment, the filter element 70 can be, but is not limited to, a filter mesh.

[0072] Please refer to Figure 2, in this embodiment, the filter element 70 is disposed in the preheater 43, and the gas output by the suction mechanism 20 is filtered by the filter element 70 and then transmitted to the evaporator 30 through the preheater 43. It can be understood that in other embodiments, the filter element 70 can be disposed in the evaporator 30 so that the gas output by the suction mechanism 20 is directly transmitted to the evaporator 30 after being filtered by the filter element 70.

[0073] In this embodiment, the drying device 100 further includes a housing 80. The evaporator 30, the compressor 50, the expansion valve 60, and the filter element 70 are disposed in the housing 80, and the suction mechanism 20 and the heating mechanism 40 are partially disposed in the housing 80. Through the setting of the housing 80, the aesthetic degree of the drying device 100 is facilitated. Specifically, the fan 22 and the guiding assembly 23 are disposed in the housing 80, the air outlet pipe 21 is connected to the working box 10 and the housing 80, the condenser 41, the heating element 421, and the preheater 43 are disposed in the housing 80, and the air supply pipe 422 is connected to the working box 10 and the housing 80.

[0074] Please refer to Figure 4 , in this embodiment, the working box 10 includes a box body 11 and a box door 12. The box body 11 has an accommodation space 111 for accommodating products. The accommodation space 111 is respectively communicated with the suction mechanism 20 and the heating mechanism 40. The box door 12 is movably disposed on the box body 11, and the box door 12 is used to cover the accommodation space 111. Specifically, the accommodation space 111 is respectively communicated with the air outlet pipe 21 and the air supply pipe 422. The suction mechanism 20 sucks the gas in the accommodation space 111 through the air outlet pipe 21, and the heating element 421 heats the gas to a preset temperature and then transmits it to the accommodation space 111 through the air supply pipe 422.

[0075] Please further refer to Figure 5 , in this embodiment, the box body 11 is provided with an air inlet 112 and an air outlet 113 that are spaced apart and communicated with the accommodation space 111. The air outlet pipe 21 is connected to the air outlet 113, and the air supply pipe 422 is connected to the air inlet 112. The suction mechanism 20 sucks the gas in the accommodation space 111 through the air outlet 113 and the air outlet pipe 21, and the heating element 421 heats the gas to a preset temperature and then transmits it to the accommodation space 111 through the air supply pipe 422 and the air inlet 112.

[0076] In this embodiment, the working box 10 further includes a placement frame 13. The placement frame 13 is disposed in the accommodation space 111, and the placement frame 13 is used to accommodate products. Specifically, the setting of the placement frame 13 facilitates the placement and taking of products. When drying products, a certain amount of products are placed in the placement frame 13. After the products are dried, the products can be taken out from the placement frame 13. When there are more products or other requirements, the placement frame 13 can also be directly taken out, and then the products can be taken out from the placement frame 13.

[0077] Please refer to Figure 4In this embodiment, the working box 10 also includes a driving component 14, which is disposed on the box body 11 and connected to the box door 12. The driving component 14 is used to drive the box door 12 to open and close. The driving component 14 drives the box door 12 to move relative to the box body 11 so that the box door 12 blocks or exposes the accommodating space 111.

[0078] In this embodiment, the driving assembly 14 includes a driving member 141, a connecting member 142 and a rotating member 143. The driving member 141 is disposed on the housing 11. The output end of the driving member 141 is rotatably connected to the connecting member 142. One end of the connecting member 142 away from the driving member 141 is fixedly connected to the rotating member 143. The axis of the connecting member 142 is perpendicular to the axis of the rotating member 143. One end of the rotating member 143 away from the connecting member 142 is fixedly connected to one end of the door 12. The driving member 141 is used to drive the connecting member 142 to rotate around the axis of the rotating member 143, so as to drive the rotating member 143 and the door 12 to rotate relative to the housing 11, so that the door 12 covers or exposes the accommodation space 111. In this embodiment, the driving member 141 can be, but not limited to, a cylinder or an electric push rod, and the connecting member 142 and the rotating member 143 can be, but not limited to, a rod-shaped structure.

[0079] In this embodiment, the driving assembly 14 further includes a protrusion 144 disposed on the housing 11, and the rotating member 143 rotates through the protrusion 144 and is fixedly connected to one end of the door 12. The arrangement of the protrusion 144 facilitates the reliability of the rotating member 143 rotating around its own axis.

[0080] In this embodiment, the box door 12 includes a first shielding portion 121 and a second shielding portion 122 that are rotatably connected. The rotating member 143 is connected to the side of the first shielding portion 121 that is away from the second shielding portion 122. The driving member 141 is used to drive the connecting member 142 to rotate around the axis of the rotating member 143 to drive the rotating member 143 and the first shielding portion 121 to rotate relative to the box body 11, so that the second shielding portion 122 is opened or folded relative to the first shielding portion 121, and then the first shielding portion 121 and the second shielding portion 122 cover or expose the accommodating space 111.

[0081] In this embodiment, the working box 10 further includes a guide rail 15 disposed on the box body 11 and a rotating wheel 123 rotatably disposed on the second shielding portion 122. The rotating wheel 123 is rollingly disposed on the guide rail 15. When the second shielding portion 122 is opened or folded relative to the first shielding portion 121, the rotating wheel 123 rolls along the guide rail 15. Specifically, the arrangement of the rotating wheel 123 and the guide rail 15 prevents the second shielding portion 122 from directly contacting and rubbing with the box body 11 when the second shielding portion 122 is opened or folded relative to the first shielding portion 121, thereby facilitating the opening or folding of the second shielding portion 122 relative to the first shielding portion 121; the guide rail 15 also guides the rolling of the rotating wheel 123 to prevent the rotating wheel 123 from running off.

[0082] In this embodiment, the number of the guide rails 15 is two, and the two guide rails 15 are arranged on the opposite sides of the box body 11. Rotating wheels 123 are rotatably arranged on the opposite sides of the second shielding part 122, and the rotating wheels 123 on the opposite sides of the second shielding part 122 are respectively arranged to roll on the two guide rails 15. Specifically, the two guide rails 15 can reliably support the rotating wheels 123 and the second shielding part 122.

[0083] In this embodiment, the number of the box doors 12 and the number of the driving components 14 are both two, and the two box doors 12 and the two driving components 14 are in one-to-one correspondence. In this embodiment, each box door 12 can shield half of the accommodating space 111, and the two box doors 12 cooperate to shield the entire accommodating space 111.

[0084] Please refer to Figure 5 , in this embodiment, the working box 10 further includes a flow guiding plate 16. The flow guiding plate 16 is arranged in the accommodating space 111, the flow guiding plate 16 faces the air inlet 112 and is arranged at an interval from the placing frame 13. Specifically, due to the arrangement of the flow guiding plate 16, after the gas conveyed to the accommodating space 111 through the air supply pipe 422 blows on the flow guiding plate 16, it enters the placing frame 13 from both sides of the flow guiding plate 16, thereby playing a role in dispersing the gas.

[0085] In this embodiment, the working box 10 further includes two oppositely arranged grid plates 17. The two grid plates 17 are located in the accommodating space 111 and on the opposite sides of the placing frame 13. The two grid plates 17 are both connected to the flow guiding plate 16. The grid plates 17 are used to evenly blow the gas into the placing frame 13. Specifically, after the gas conveyed to the accommodating space 111 through the air supply pipe 422 blows on the flow guiding plate 16, it flows to the area where the grid plates 17 are located from both sides of the flow guiding plate 16. After the gas is evenly dispersed by the grid plates 17, it enters the placing frame 13, so that the gas can evenly blow on the products, and then reliably dry the products.

[0086] The operation process of the drying device 100 according to the embodiment of the present application is generally as follows:

[0087] When removing the moisture on the surface of the product using the above drying device 100, the product is placed in the placement frame 13 within the working chamber 10. The blower 22 extracts the gas within the working chamber 10 through the air outlet pipe 21 and outputs the gas to the evaporator 30 after guiding by the guiding assembly 23. The evaporator 30 is used to condense and dry the gas output by the blower 22, so that the moisture in the gas forms condensate. Thus, the evaporator 30 outputs the dry gas to the preheater 43. The preheater 43 preheats the gas and outputs the preheated gas to the condenser 41. The condenser 41 releases heat to the gas inside the condenser 41 to increase the temperature of the gas inside the condenser. The heating element 421 further heats the gas to the preset temperature and outputs it to the working chamber 10 through the air supply pipe 422, so that the gas at the preset temperature entering the working chamber 10 dries the product.

[0088] The drying device 100 provided by the embodiment of the present application, through the cooperation of the working chamber 10, the suction mechanism 20, the evaporator 30 and the heating mechanism 40, enables the gas to circulate and flow, and enables the gas at the preset temperature to flow and input into the working chamber 10. Thus, the gas at the preset temperature flowing in the working chamber 10 blows the product to achieve the drying of the product; by setting the guiding assembly 23, the gas output by the blower 22 is guided and transmitted to the evaporator 30; through the cooperation of the compressor 50, the evaporator 30 and the condenser 41, the refrigerant and the gas have two heat exchanges. The heat absorbed by the gas by the refrigerant in the evaporator 30 is released to the gas by the refrigerant in the condenser 41 again, and the heat of the gas is reused, thus reducing the energy consumption; by setting the filter element 70, it is convenient to improve the purity of the gas; through the setting of the flow guiding plate 16 and the grid plate 17, the gas enters the working chamber 10 after being evenly dispersed by the grid plate 17, so that the gas can evenly blow the product, and further reliably dry the product.
