Description

Technical Field

[0002] With the continuous improvement of people's living standards, people's awareness of hygiene has gradually increased. Most users attach more importance to the care function and cleanliness of clothes. However, simple washing of clothes cannot completely eliminate microorganisms such as viruses or bacteria. The main reason is that the washing machine cannot clean the heat pump system, and long-term use will cause the growth of microorganisms such as viruses or bacteria in the high-humidity and high-temperature areas of the heat pump system. Although in the prior art, washing machines with heat pump drying mode have emerged, and relevant solutions have been proposed for the cleaning problem of the heat pump. For example, a water spray device is set in the heat pump to spray and clean the evaporator and condenser in the heat pump system. However, from the actual product feedback, only spraying water to clean the evaporator and condenser can only clean dirt with weak adhesiveness such as dust, and it is obvious that it cannot clean highly viscous dirt such as viruses or bacteria that are easily adhered to the two devices in the heat pump system. Generally speaking, this cleaning solution in the prior art has a high cost and occupies a large space, but the sterilization and decontamination effect is not very obvious. Summary of the Invention

Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0036] To solve the technical problems in the prior art that a heat pump washing machine cannot self-clean the heat pump and cannot clean clothes thoroughly, this application provides a drying system and a laundry treatment device including the same. The following will elaborate on the specific embodiments of this application in detail.

[0037] Figure 1 This is a schematic diagram of the structural positions of the components of a drying system and a laundry treatment device including the same provided in the embodiments of this application.

[0038] Figure 2 This is a schematic diagram of the structural positions of the air duct explosion structure of a drying system and a laundry treatment device including the same provided in the embodiments of this application.

[0039] According to the specific embodiments of this application, as Figure 1 and Figure 2 shown, this application mainly provides a drying system. The drying system includes an air duct, a fan 10, a heat exchanger 20, and a generating device 30. The air duct includes an air outlet 41 and an air inlet 42. The fan 10 is disposed in the air duct. The fan 10 drives the air flow to circulate from the air inlet 42 to the air outlet 41, forming a circulating air flow in the air duct. The heat exchanger 20 is also disposed in the air duct and is used for heat exchange with the flowing gas. And the heat exchanger 20 is installed between the air outlet 41 and the fan 10. The generating device 30 is also disposed in the air duct, and the generating device 30 is located between the heat exchanger 20 and the fan 10. The generating device 30 can generate oxidation free radicals and release the oxidation free radicals into the circulating air duct.

[0040] In a specific embodiment of the present application, the technical inspiration embodied is that an air duct is formed inside the drying system. A fan 10 and a heat exchanger 20 are arranged in the air duct. The air duct includes an air outlet and an air inlet. The fan drives the air flow to circulate from the air inlet to the air outlet, so that a circulating air flow is formed inside the entire air duct. The heat exchanger 20 is installed between the air outlet and the fan to exchange heat of the flowing gas. A generating device 30 is also arranged in the air duct. The generating device 30 is located between the heat exchanger 20 and the fan 10, and the generating device 30 can generate oxidation free radicals. Under the action of the circulating air flow, the oxidation free radicals can be released into the interior of the heat exchanger 20 downstream of the air flow, so as to clean the heat exchanger with substances containing oxidation free radicals. Since substances containing oxidation free radicals have a better cleaning effect on highly viscous dirt such as viruses, bacteria and other microorganisms adhering to the heat exchanger, the self-cleaning effect of key areas of the heat exchanger 20 in these drying systems can be significantly improved. Therefore, as long as the above relevant technical inspirations are utilized, they all fall within the protection scope of the present application.

[0041] It should be noted that in the embodiment of the present application, the generating device 30 can generate oxidation free radicals, which can utilize the oxidizing property to strip the organic molecules of the stains, and then destroy the cell structure, achieving the characteristic of strong decontamination. The generating device 30 is arranged between the heat exchanger 20 and the fan 10, and the circulating air flow can bring the oxidation free radicals generated by the generating device 30 into the interior of the heat exchanger 20 for cleaning. At the same time, the free radicals with oxidizing property will also oxidize and corrode the heat exchanger 20. Therefore, in the specific embodiment of the present application, the following scheme is adopted to protect the heat exchanger 20 against oxidation;

[0042] Scheme 1; The surface of the heat exchanger 20 needs to be pre-treated against oxidation. Conventional operation methods in the prior art can be used, such as electroplating, alloying, bluing treatment, painting, direct calcination, etc. Then a dense oxide film is formed on the surface of the heat exchanger 20 to achieve anti-oxidation treatment, prevent the long-term corrosion of the heat exchanger 20 by oxidation free radicals, and extend the service life of the heat exchanger 20.

[0043] Scheme 2; A detector is installed in the drying system. The detector can detect the output power of the drying system and the heat conductivity of the heat exchanger 20. Generally speaking, the output power of the drying system is proportional to the heat conductivity of the heat exchanger 20, that is, the heat conductivity of the heat exchanger 20 will increase with the increase of the output power of the drying system. If the detector detects that the output power increases while the heat conductivity does not increase correspondingly, it means that high-viscosity bacteria or microorganisms have grown on the surface of the heat exchanger 20. At this time, the generating device 30 will be started to generate oxidation free radicals to clean it, and it will be turned off after cleaning.

[0044] Solution 3: A sensor is installed on the heat exchanger 20. The sensor can detect whether substances such as high-viscosity microorganisms and bacteria grow on the surface of the heat exchanger. If the sensor detects that microorganisms, bacteria and other substances have grown on the surface of the heat exchanger 20, the generating device 30 is activated to clean it, and it is turned off after the cleaning is completed.

[0045] Both Solution 2 and Solution 3 utilize the intermittent opening and closing of the generating device 30. The generating device 30 is only required to be activated when cleaning is needed and turned off when cleaning is not required, avoiding the generating device 30 being in an always-on state, reducing the time for oxidation radicals to corrode the heat exchanger 20, and being able to extend the service life of the heat exchanger 20.

[0046] In a specific embodiment of the present application, it should also be noted that the generating device 30 and the cover body 22 are connected by a snap connection method. Specifically, positioning holes can be provided on the generating device 30, and positioning posts are provided at positions corresponding to the positioning holes on the cover body 22, and vice versa, to achieve the pre-positioning effect during the installation of the generating device 30, facilitating installation, saving assembly time, and further improving work efficiency. Among them, the specific connection method between the first heat exchanger 23 and the second heat exchanger 24 can adopt a bolt fixation method to integrate the structures of the first heat exchanger 23 and the second heat exchanger 24, facilitating assembly and disassembly, reducing the working space, and making the structural design more compact.

[0047] According to the specific implementation manner of the present application, as Figure 1 and Figure 2 shown, the drying system further includes a heat exchanger box 21. The heat exchanger box 21 is provided with an air inlet 211 and an air outlet 212. The air inlet 211 is connected to the blower 10, and the air outlet 212 is connected to the front air duct 70. Starting the blower 10 can cause the gas to pass through the heat exchanger 20 from the air inlet 42, and then enter the exhaust port 41 from the front air duct 70. In this way, a circulating airflow in the air duct is formed. The heat exchanger 20 is installed in the heat exchanger box 21. The heat exchanger 20 is located on the side closer to the air outlet 212 relative to the generating device 30. That is to say, the heat exchanger 20 is between the air inlet 211 and the air outlet 212, while the generating device 30 is arranged between the air inlet 211 and the blower 10. Just such a positional relationship can enable the oxidation radicals generated by the generating device 30 to enter from the air inlet 211 in the circulating airflow driven by the blower 10, flow through the heat exchanger 20 and then flow out from the air outlet 212 to achieve the effect of cleaning the heat exchanger 20.

[0048] According to the specific implementation manner of the present application, as Figure 1 and Figure 2As shown, the blower 10 includes a blower housing 11 and a fan 12. The fan 12 is disposed within the blower housing 11. The first end 111 of the blower housing 11 is connected to the air inlet 211 of the heat exchanger box 21, and the second end 112 of the blower housing 11 is the air inlet 42. In this way, the oxidation radicals in the circulation air duct are introduced from the air inlet 42 into the air inlet of the heat exchanger box 21, so that they can flow through the surface of the heat exchanger 20. The first end 71 of the front air duct 70 is connected to the air outlet 212 of the heat exchanger box 21, and the second end 72 of the front air duct 70 is the exhaust port 41. In this way, the oxidation radicals flowing through the heat exchanger 20 can be exported from the air outlet 212 again, and then the oxidation radicals are introduced from the exhaust port 41 into the air inlet 42 through the front air duct 70. In this way, the oxidation radicals can continuously flow through the surface of the heat exchanger 20 in the circulating air duct to clean it.

[0049] According to the specific embodiments of the present application, as Figure 1 and Figure 2 shown, the heat exchanger box 21 includes a main body and a cover 22. A heat exchange cavity is formed within the main body, and the cover 22 covers the open mouth of the heat exchange cavity. The generating device 30 is installed on the cover 22. Among them, the heat exchanger 20 includes a first heat exchanger 23 and a second heat exchanger 24. The first heat exchanger 23 and the second heat exchanger 24 are arranged in sequence along the air flow direction, and the top surfaces of the first heat exchanger 23 and the second heat exchanger 24 are both lower than the height of the outlet 32 of the generating device 30.

[0050] In a specific embodiment, the first heat exchanger 23 may be an evaporator, and the second heat exchanger 24 may be a condenser. Specifically, the generating device 30 can be installed at the lower rear side of the cover 22 and close to the evaporator side. With such a position design, it can be ensured that electrolysis can occur even when the water level in the evaporator is relatively low, ionizing water molecules to form highly active oxidation radicals to clean the heat exchanger 20, and further preventing the phenomenon of electrolysis interruption of the generating device 30. Specifically, making the top surfaces of the first heat exchanger 23 and the second heat exchanger 24 both lower than the height of the outlet 32 of the generating device 30 is aimed at creating a certain height difference between the generating device 30 and the heat exchanger 20. When the oxidation radicals generated by the generating device 30 flow out from the outlet 32, under the action of gravity and the blower 10, the oxidation radicals can be evenly and comprehensively sprayed on the surface of the heat exchanger 20, achieving the effect of cleaning the heat exchanger 20 in all aspects.

[0051] According to the specific embodiments of the present application, as Figure 1 and Figure 2As shown, the generating device 30 is a hydroxyl substance generating device. Because hydroxyl radical is an important reactive oxygen species. From the molecular formula, it is formed by the loss of an electron from the hydroxide ion (OH-), resulting in the hydroxyl radical having extremely strong electron-gaining ability, that is, oxidation ability. Its oxidation potential is 2.80 eV, which is the second most powerful oxidant in nature after fluorine. Moreover, the bactericidal and virucidal effects of hydroxyl radicals mainly stem from their strong oxidizing property. When hydroxyl radicals come into contact with microorganisms, they can rapidly decompose into nascent oxygen. The nascent oxygen enters the interior of the microorganisms, causing the relevant enzymes of the bacteria to denature or destroying the nucleic acid structure of the virus, thereby killing the bacteria and inactivating the virus. It is precisely by utilizing the characteristic that hydroxyl radicals have the strongest oxidizing property that the organic molecules of the stains on the heat exchanger 20 can be stripped, and then the cell structure is damaged, achieving the purpose of powerful decontamination.

[0052] According to the specific embodiments of the present application, as Figure 3 and Figure 4 shown, the generating device 30 has a generating chamber. The generating chamber is provided with an inlet 31 and an outlet 32. A fluid passage is provided between the inlet 31 and the outlet 32 for the raw material liquid to flow from the inlet 31 to the outlet 32 in the fluid passage; a first electrode 50 and a second electrode 60 are respectively provided on both sides of the fluid passage to electrolyze the flowing raw material liquid to generate oxidation radicals.

[0053] In a specific embodiment, specifically, multiple segments of the fluid passage can be arranged at intervals in the generating chamber. The fluid passages are connected end to end in sequence to form a circuitous fluid passage, so that the total length of the multiple segments of the fluid passage is greater than the straight-line distance from the inlet 31 to the outlet 32, in order to increase the residence time of the raw material liquid in the generating chamber, enabling the generating device 30 to electrolyze the raw material liquid, thereby generating more oxidation radicals. Specifically, the first electrode 50 and the second electrode 60 can divide the generating chamber into multiple segments of the fluid passage; the first electrode 50 and the second electrode 60 extend in a first direction 100, and the raw material liquid flows in a second direction 110 at the inlet 31 and / or the outlet 32. Since the first direction 100 and the second direction 110 are perpendicular to each other, when the raw material liquid flows into the generating chamber from the inlet 31, it will fully contact the first electrode 50 and the second electrode 60, increasing the contact area with the raw material liquid to electrolyze and generate more oxidation radicals.

[0054] In a specific embodiment of the present application, the first electrode 50 and the second electrode 60 may specifically be electrolysis devices that electrolyze the flowing raw material liquid to generate strongly oxidizing hydroxyl radicals. The first electrode 50 and the second electrode 60 may preferably adopt a rectangular structure. Since the raw material liquid flows out from the inlet 31 to the outlet 32 along the second direction 110 in the up-down direction, the first electrode 50 and the second electrode 60 extend along the first direction 100 in the left-right direction in the reaction chamber and are placed in a balanced and staggered manner to form a meandering fluid channel. This structure can further increase the contact area with the raw material liquid, greatly improve the electrolysis rate, generate more active substances such as hydroxyl radicals, and at the same time produce a large number of microbubbles, which can enhance the sterilization and anti-color bleeding effects. In addition, the raw material liquid can flow from one side of the electrode plate to the other side, and the water flow can timely carry away the microbubbles on the surface of the electrode plate to prevent the microbubbles from aggregating into large bubbles, solving the problem of generating large bubbles during the electrolysis of the reaction device.

[0055] In a specific embodiment, the first electrode 50 and the second electrode 60 are arranged in an interleaved manner in the reaction chamber to divide the reaction chamber into multiple sections of fluid channels. The head and tail of each fluid channel are connected to form a meandering fluid channel. When the raw material liquid enters from the inlet 31, it needs to pass through multiple fluid channels in sequence before flowing out from the outlet 32. The purpose is to increase the time and distance required for the raw material liquid to flow from the inlet 31 to the outlet 32, so that the first electrode 50 and the second electrode 60 can be in full contact with the raw material liquid to generate more hydroxyl radicals.

[0056] According to the specific implementation manner of the present application, as Figure 3 and Figure 4 shown, the first electrode 50 includes a first wall body 51 and a second wall body 52, and the second electrode 60 includes a third wall body 61 and a fourth wall body 62. The first electrode 50 and the second electrode 60 are arranged relatively and staggered. Multiple first fluid channels 33, second fluid channels 34, third fluid channels 35, fourth fluid channels 36 and fifth fluid channels 37 are formed between the first wall body 51 and the second wall body 52 of the first electrode 50 and the third wall body 61 and the fourth wall body 62 of the second electrode 60.

[0057] In a specific embodiment, the first wall 51, the second wall 52, the third wall 61, and the fourth wall 62 may specifically be a cathode electrolytic plate and an anode electrolytic plate. The first wall 51 and the second wall 52 are designed to be parallel and staggered with the third wall 61 and the fourth wall 62, dividing the reaction chamber into a first fluid channel 33, a second fluid channel 34, a third fluid channel 35, a fourth fluid channel 36, and a fifth fluid channel 37. Due to this staggered arrangement design, the cathode electrolytic plates and anode electrolytic plates in the first electrode 50 and the cathode electrolytic plates and anode electrolytic plates in the second electrode 60 form multiple electrolysis reaction fields. Moreover, each electrolytic plate is provided with first and second comb teeth, and the same spacing width is provided between each pair of comb teeth. The purpose is to improve the electrolysis efficiency, block part of the water flow, reduce the flow rate of the water flow, ensure full contact of the electrolytic plates, achieve the purpose of fully electrolyzing water molecules in the generating device 30, prevent a small amount of fluff from clogging on the generating device 30, increase the service life of the generating device 30, and prevent short circuits caused by contact between the electrolytic cathode and the electrolytic anode.

[0058] In a specific embodiment, the outer shape of the electrolytic plate may specifically be rectangular. Since the structure of the reaction chamber is also rectangular, the top surface of the electrolytic plate contacts the top surface of the reaction chamber, and the bottom surface of the electrolytic plate contacts the bottom surface of the reaction chamber, dividing the reaction chamber into multiple fluid channels to form a tortuous fluid channel, increasing the time required for the raw material liquid to pass through the fluid channel, ensuring full contact with the electrolytic plate, and the size of the electrolytic plate can be changed according to the space size of the heat exchanger 20 in the heat exchanger box 21 in the drying system. This structure can greatly improve the electrolysis rate, generate more active substances such as hydroxyl radicals, the water flow can flow from one side of the electrode plate to the other side, and the water flow can timely carry away the microbubbles on the surface of the electrode plate and the inner wall surface of the electrolytic through-hole.

[0059] According to the specific implementation manner of the present application, as Figure 3 and Figure 5 shown, the outlet 32 includes a plurality of ejection holes 38. The plurality of ejection holes 38 are arranged at intervals in the first direction 100, the directions of the plurality of ejection holes 38 are all in the second direction 110, and the directions of the plurality of ejection holes 38 are the same as the air flow direction of the air duct.

[0060] In a specific embodiment, since the generating device 30 is installed on the lower rear side of the cover body 22, and the top surfaces of the first heat exchanger 23 and the second heat exchanger 24 are both lower than the height of the outlet 32 of the generating device 30, when the raw material liquid enters from the inlet 31, it will flow through to the outlet 32 in sequence along the first direction 100 of the plurality of fluid channels. A plurality of ejection holes 38 are provided on the outlet 32. The hydroxyl radicals can be evenly sprayed inside the heat exchanger 20 through the plurality of ejection holes 38, capable of cleaning and sterilizing the heat exchanger 20. Then, the hydroxyl radicals will enter the outer cylinder 80 through the front air duct 70, capable of acting on the clothes, achieving effects such as sterilizing, disinfecting, and deodorizing the clothes; in addition, the generating device 30 electrolyzes the raw material liquid, and the generated hydroxyl radicals have strong oxidizing properties, stripping the organic molecules of the stains on the clothes, thereby destroying the cell structure, achieving the purpose of powerful stain removal, further improving the washing effect of the clothes, increasing the washing ratio of the washing machine, and meeting the cleanliness requirements of most users.

[0061] The embodiment of the present application further provides a clothes treatment device, including the heat pump in the foregoing embodiment.
