[0002] Traditional electric dryers generally provide heat sources by heating with electric heating wires, which results in a lot of heat waste and high energy consumption.

DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0045] According to an exemplary embodiment, this embodiment provides a clothes processing device with a drying function. The clothes processing device of this embodiment may have only a drying function, or may have both a drying function and a washing function. Figure 1-Figure 5 As shown, the clothes processing device of this embodiment includes a box body 501, and a left cover plate 502 and a right cover plate 503 are respectively provided on the left and right sides of the box body 501, an upper cover plate 504 is provided on the top of the box body 501, a bottom plate 505 is provided on the bottom, a back cover plate 506 is provided on the back, and a front cover plate 507 is provided on the front. The front cover plate 507 is provided with a avoidance opening opposite to the barrel opening of the barrel body 200. A front panel 601 is provided on the outside of the front cover plate 507, and a delivery opening is provided at the position of the front panel 601 corresponding to the avoidance opening, and a door body 602 is provided at the delivery opening, and the door body 602 is hinged at the delivery opening.

[0046] The clothing processing device comprises a drum 200, two-device assembly 100, auxiliary heating device 3, temperature detection device and control device (not shown in the figure). The drum 200 is provided with a drying air inlet 220 and a drying air outlet 210, the two-device assembly 100 comprises an evaporator 21 and a condenser 22, and the drying air outlet 210, the evaporator 21, the condenser 22 and the drying air inlet 220 are connected in sequence. Specifically, the two-device assembly 100 includes a shell 1, which includes a bottom shell 12 and an upper cover 13. The bottom shell 12 and the upper cover 13 enclose a shell cavity 11. The bottom shell 12 is provided with an air inlet 14 and an air outlet 15. The evaporator 21 and the condenser are arranged in the shell cavity 11 and are located between the air inlet 14 and the air outlet 15. The evaporator 21 is arranged close to the air inlet 14, and the condenser 22 is arranged close to the air outlet 15. The air inlet 14 is connected to the drying air outlet 210 through the air outlet duct 400, and the air outlet 15 is connected to the drying air inlet 220 through the air inlet duct 300. The clothing processing device also includes a fan, which is arranged in the air inlet duct 300 or the air outlet duct 400. During the drying process, the hot and humid air flow in the cylinder 200 enters the shell cavity 11 through the air outlet duct 400 under the action of the fan, and is condensed by the evaporator 21 to form dry cold air. The dry cold air enters the condenser 22 and is heated by the condenser 22 to form dry hot air. The dry hot air enters the cylinder 200 through the air inlet duct 300, and the cycle is repeated.

[0047] The auxiliary heating device 3 is embedded in the condenser 22, and the auxiliary heating device 3 includes a plurality of heating components, and the plurality of heating components have different heating powers. The auxiliary heating device 3 is embedded in the condenser 22 to effectively reduce the air flow resistance, thereby reducing the fan energy consumption. The temperature detection device includes a plurality of temperature detection components, and the plurality of temperature detection components are arranged at different positions of the clothing processing device to at least detect the ambient temperature of the condenser 22, the air inlet temperature of the barrel 200, and the air outlet temperature of the barrel 200. The temperature detection device includes at least a first temperature detection component, a second temperature detection component, and a third temperature detection component, wherein the first temperature detection component is arranged in the air outlet duct 400 or at the drying air outlet 210, and is used to detect the air outlet temperature of the barrel 200, the second temperature detection component is arranged in the air inlet duct 300 or at the drying air inlet 220, and is used to detect the air inlet temperature of the barrel 200, and the third temperature detection component is arranged around the condenser 22, and is used to detect the ambient temperature of the condenser 22.

[0048] The control device is electrically connected or signal-connected with the temperature detection device and the auxiliary heating device 3. The control device receives the temperature data detected by the temperature detection device and sends a control instruction to the auxiliary heating device 3 according to the temperature data. The control device is configured to control the opening state of multiple heating components according to the ambient temperature, the air inlet temperature and / or the air outlet temperature in different drying stages of the clothing processing device, so as to reasonably control the heat supply and heating time of the auxiliary heating device 3, realize heating of the condenser 22 and the air flow passing through the condenser 22, quickly improve the heat exchange efficiency of the heat pump system and shorten the drying time. At the same time, multiple heating components are embedded in the condenser 22 without increasing the flow resistance and fan energy consumption.

[0049] In some embodiments, a plurality of heating components are sequentially arranged along the airflow direction inside the condenser 22, the heating component located upstream in the airflow direction is arranged close to the evaporator 21, and the heating component located downstream in the airflow direction is arranged away from the evaporator 21. Since the ambient airflow flow of the condenser 22 is weak, the airflow flow at the air outlet of the condenser 22 is strong, and it is difficult to reach the target air inlet temperature of the barrel 200, the heating power of the heating component located upstream in the airflow direction is set to be less than the heating power of the heating component located downstream in the airflow direction.

[0050] The drying program of the clothes processing device of this embodiment includes a plurality of drying stages executed sequentially. In the first drying stage, which is at the early stage of the clothes drying program, the humidity of the dried articles in the drum 200 is relatively high, and it is necessary to generate hot airflow efficiently and quickly to improve the drying efficiency. When the airflow flowing out of the evaporator 21 just enters the condenser 22, the heating effect of the condenser 22 on the airflow is not significant. At this time, the surface temperature of the condenser 22 near the evaporator 21 reflects the ambient temperature of the condenser 22. When the heating component located upstream of the airflow direction starts heating, it is more likely to affect the ambient temperature of the condenser 22. The ambient temperature can be increased by controlling the heating component located upstream of the airflow direction to start, thereby improving the heat exchange efficiency of the condenser 22. As the airflow flows inside the condenser 22, the airflow is gradually heated by the condenser 22. When the heating component located downstream of the airflow direction starts heating, it is more likely to affect the air inlet temperature of the drum 200 (i.e., the air outlet temperature of the condenser 22). The air inlet temperature can be increased by controlling the heating component located downstream of the airflow direction to start, thereby improving the dehumidification efficiency. In addition, when the drying program is in the second drying stage at the later stage of drying, the temperature difference between the inlet air temperature and the outlet air temperature of the drum 200 reflects the drying condition of the dried objects in the drum 200. Therefore, the start-up status of multiple heating components can also be controlled simultaneously according to the inlet air temperature and the outlet air temperature, thereby accelerating drying and reducing energy consumption.

[0051] In some embodiments, Figure 1 and Figure 3As shown, the plurality of heating components include a first heating component 31 and a second heating component 32. The first heating component 31 is arranged away from the air outlet of the condenser 22, and the second heating component 32 is arranged close to the air outlet of the condenser 22. The heating power of the second heating component 32 is greater than the heating power of the first heating component 31. The first heating component 31 heats the fins of the condenser 22 close to the evaporator 21 to increase the ambient temperature of the condenser 22. Since the air flow in the environment of the condenser 22 is weak, it is easier to reach the target ambient temperature, so the heating power requirement of the first heating component 31 is relatively low; the second heating component 32 is mainly used to heat the fins of the condenser 22 away from the evaporator 21 to significantly increase the inlet air temperature of the cylinder 200. The air flow in the condenser 22 is relatively large, and it is difficult to reach the target inlet air temperature. Therefore, the power requirement of the second heating component 32 is relatively high. In this embodiment, the first heating component 31 and the second heating component 32 can be arranged adjacent to each other, and the first heating component 31 and the second heating component 32 can also be embedded at different positions inside the condenser 22 at intervals. In a preferred embodiment, the second heating component 32 is disposed close to a wall surface of the condenser 22 that is away from the evaporator 21 , so as to better increase the inlet air temperature of the cylinder 200 .

[0052] The control device is configured to: in the first drying stage of the drying program, control the start state of the first heating component 31 according to the ambient temperature, and control the start state of the second heating component 32 according to the inlet air temperature. In this embodiment, the first drying stage is, for example, the early drying stage, at which the ambient temperature of the condenser 22 is low and the humidity of the dried object in the barrel 200 is high. In order to quickly make the inlet air temperature of the barrel 200 reach a high temperature, the start states of the first heating component 31 and the second heating component 32 are controlled respectively by combining the ambient temperature of the condenser 22 and the inlet air temperature of the barrel 200.

[0053] Specifically, when the ambient temperature of the condenser 22 is less than or equal to the first set temperature, the ambient temperature of the condenser 22 is low, and the heat exchange efficiency of the condenser 22 is low. Therefore, it is necessary to quickly increase the surface temperature of the condenser 22 by turning on the first heating component 31 to improve the heat exchange efficiency. When the ambient temperature of the condenser 22 is greater than the first set temperature, the ambient temperature of the condenser 22 is high. In order to avoid overheating protection of the condenser 22, the first heating component 31 needs to be turned off. Similarly, when the air inlet temperature of the barrel 200 is less than or equal to the second set temperature, the air inlet temperature of the barrel 200 is low, and the drying efficiency of the clothes in the barrel 200 is low and the drying time is long. Therefore, it is necessary to quickly increase the air inlet temperature of the barrel 200 by turning on the second heating component 32. When the air inlet temperature is greater than the second set temperature, the air inlet temperature of the barrel 200 is high. In order to avoid the compressor from running at a reduced frequency, the second heating component 32 needs to be turned off. Therefore, this embodiment controls the startup state of the first heating component 31 by combining the ambient temperature of the condenser 22, and controls the startup state of the second heating component 32 by combining the inlet air temperature of the cylinder 200, which can effectively ensure that the surface temperature of the condenser 22 and the heat exchange efficiency of the heat pump system are quickly increased under low ambient temperature conditions in the first drying stage, and at the same time, the drying air temperature can be increased and the drying time in the early stage of drying can be shortened.

[0054] In some embodiments, the control device is further configured to: in the second drying stage of the drying program, control the opening state of the first heating component 31 and the second heating component 32 according to the temperature difference between the inlet air temperature and the outlet air temperature. The humidity of the dried object in the drum 200 in the first drying stage is greater than the humidity of the dried object in the drum 200 in the second drying stage.

[0055] In this embodiment, the second drying stage is, for example, the late drying stage. In the late drying stage, the humidity of the clothes in the drum 200 is relatively low. By controlling the opening state of the first heating component 31 and the second heating component 32 according to the temperature difference between the inlet air temperature and the outlet air temperature of the drum 200, when the temperature difference between the inlet air temperature and the outlet air temperature is within the target temperature difference range, it is only necessary to control the opening of the second heat exchange component which has a greater influence on the inlet air temperature to meet the inlet air temperature requirement, while avoiding the frequency reduction problem caused by the excessive temperature of the heat pump system, thereby shortening the drying time and reducing energy consumption. When the temperature difference is less than the minimum value of the target temperature difference range, it means that the temperature difference between the inlet air temperature and the outlet air temperature is relatively small at this time, and the clothes in the drum 200 are in a state of being about to be dried or already dried. At this time, the first heating component 31 and the second heating component 32 can be turned off. When the temperature difference is greater than the maximum value of the target temperature difference range, it means that the temperature difference between the inlet air temperature and the outlet air temperature is relatively large at this time, and the humidity of the clothes in the drum 200 is relatively high. It is necessary to turn on the first heating component 31 and the second heating component 32 at the same time to ensure the inlet air temperature and improve the drying efficiency.

[0056] In some embodiments, Figure 1 and Figure 3 As shown, the first heating component 31 includes at least one first electric heating tube, the second heating component 32 includes at least one second electric heating tube, the condenser 22 includes a plurality of fins and a plurality of condensing tubes 221, the plurality of fins are stacked, and an airflow path is formed between adjacent fins. The dry cold air entering the condenser 22 exchanges heat with the condensing tube 221 through the airflow path, and a high-temperature refrigerant flows in the condensing tube 221. The dry cold air is heated by the high-temperature refrigerant to form a dry hot air flow, and the dry hot air flows through the air inlet channel into the drum 200 to dry the clothes. The condenser 22 is provided with a plurality of first channels (not shown in the figure), at least one second channel 222 and at least one third channel 223. The plurality of first channels, at least one second channel 222 and at least one third channel 223 all penetrate the plurality of fins in a direction perpendicular to the fins. The plurality of condensing tubes 221 are arranged in the plurality of first channels one by one, the at least one first electric heating tube is arranged in the at least one second channel 222 one by one, and the at least one second electric heating tube is arranged in the at least one third channel 223 one by one.

[0057] In a preferred embodiment, the diameters of the first passage, the second passage 222 and the third passage 223 are the same, the diameters of the first electric heating tube and the second electric heating tube are consistent with the diameters of the condenser 221, and one end of the adjacent condenser tubes 221 is connected by a bend joint to connect each condenser tube 221 in series. The condenser tube 221, the first electric heating tube and the second electric heating tube are respectively adapted to the sizes of the first passage, the second passage 222 and the third passage 223, so that when the condenser tube 221 and the electric heating tube are respectively assembled into the first passage, the second passage 222 and the third passage 223, they are in close contact with the fins of the condenser 22, reducing the heat transfer resistance, and the electric heating tube of this embodiment does not occupy additional space, has a simple structure, and does not increase the flow resistance of the airflow. At the same time, the first passage, the second passage 222 and the third passage 223 can all be adapted to the condenser tube 221, the first electric heating tube and the second electric heating tube, and the setting positions of the condenser tube 221, the first electric heating tube and the second electric heating tube can be adjusted as needed.

[0058] It should be noted that the number of electric heating tubes corresponding to different heating components of this embodiment is not limited. In one example, the first heating component 31 and the second heating component 32 each correspond to an electric heating tube, and the heating power of each electric heating tube is different. In another example, the first heating component 31 and the second heating component 32 correspond to different numbers of electric heating tubes, and the heating power of each electric heating tube can be the same or different. For example, the first heating component 31 and the second heating component 32 each correspond to an electric heating tube, and the power of the electric heating tube of the first electric heating tube part is less than the power of the electric heating tube of the second heating component 32. In another example, the first heating component 31 corresponds to one electric heating tube, and the second heating component 32 corresponds to two electric heating tubes, and the heating power of the electric heating tube corresponding to the first heating component 31 is the same as the power of the electric heating tube corresponding to the second heating component 32. In the actual production process, the number of electric heating tubes can be flexibly designed after comprehensive consideration of heating effect, production cost and other aspects. The arrangement of the multiple electric heating tubes in the condenser 22 and the power variation trend of this embodiment can quickly increase the ambient temperature of the condenser 22 and the heat exchange efficiency of the heat pump system under low ambient temperature conditions, while increasing the drying air temperature and shortening the drying time.

[0059] This embodiment adjusts the start-up state of the first heating component 31 and the second heating component 32 according to the real-time changes in the ambient temperature of the condenser 22 and the drying air temperature, thereby improving the adaptability of the control of the auxiliary heating device 3 to the drying requirements of the heat pump type clothes drying equipment, thereby achieving the purpose of shortening the drying time and avoiding the auxiliary heating device 3 from being continuously turned on at a constant power, reducing energy consumption and achieving energy saving.
