In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.
[0034] The present application embodiment provides a clothes processing device. Figure 1 and Figure 2 The clothes treating device comprises a barrel assembly 100, an air duct 200a and a thermosetting elastomer structure 20. The barrel assembly 100 has a clothes treating chamber 100a, and the air duct 200a is communicated with the clothes treating chamber 100a.
[0035] The laundry processing chamber 100a is used to accommodate laundry to be processed, and the air duct 200a is used to flow air into the laundry processing chamber 100a to dry the laundry.
[0036] The air duct 200a refers to the general term for the structure corresponding to the air flow path.
[0037] The thermosetting elastomer structure 20 is disposed on the airflow path of the air duct 200 a , that is, the airflow will flow through the thermosetting elastomer structure 20 .
[0038] It can be understood that the thermosetting elastomer structure 20 is a component with thermosetting and elastic properties, which has good high temperature resistance. When heated, the surface material is difficult to flow and has a stable shape. It can be used to seal or connect different components due to its elastic characteristics.
[0039] See also Figure 1 The surface of the thermosetting elastomer structure 20 includes an air guiding surface 20a and a non-air guiding surface 20b. The air guiding surface 20a is used to contact the airflow in the air duct 200a, while the non-air guiding surface 20b is less or even not in contact with the airflow in the air duct 200a than the air guiding surface 20a. When the clothes processing device is in operation, the airflow moves in a direction in the air duct 200a and passes over the air guiding surface 20a of the thermosetting elastomer structure 20.
[0040] Among them, the roughness of the wind-guiding surface 20a is less than the roughness of the non-wind-guiding surface 20b. It should be noted that roughness is a physical property of the surface of an object. The smaller the roughness, the smoother the surface; the greater the roughness, the more obvious the rough peaks on the surface. When airflow flows over the surface of an object, the greater the roughness of the surface, the greater the friction between the airflow and the surface of the object; the smaller the roughness of the surface, the smaller the friction between the airflow and the surface of the object.
[0041] Exemplarily, the relative size detection method of the roughness of the wind-guiding surface 20a and the non-wind-guiding surface 20b includes but is not limited to: the first method is to use a dynamometer to drag the same weight to move on the wind-guiding surface 20a and the non-wind-guiding surface 20b respectively, and the reading of the dynamometer is smaller when the weight moves on the wind-guiding surface 20a. The second method is to use a roughness meter (or profilometer) to detect the roughness of the wind-guiding surface 20a and the non-wind-guiding surface 20b respectively, and obtain the roughness value, and the roughness value of the wind-guiding surface 20a is smaller than the roughness value of the non-wind-guiding surface 20b.
[0042] Methods that can reduce the roughness of the air guide surface 20a include but are not limited to: first, a mechanical surface processing method, grinding the air guide surface 20a with a tool; second, a chemical surface treatment method, treating the air guide surface 20a with chemical reagents, etc.
[0043] In the related art, the surface roughness of the thermosetting elastomer structure hardly changes, that is, the air guide surface 20a is not subjected to relevant surface processing before being installed in the clothes processing device.
[0044] In the embodiment of the present application, since the roughness of the air guide surface 20a is small, its touch is more delicate and smooth, the friction between the air guide surface 20a and the airflow is more slight, the transfer of charge between the two is more difficult, and it is difficult to generate static electricity, which makes the thermosetting elastomer structure 20 less effective in adsorbing fluff in the airflow, reduces the growth of microorganisms, and is beneficial to maintaining the cleanliness of the air duct 200a.
[0045] It should be noted that the evaluation dimension of surface roughness is not limited, and can be the profile arithmetic mean deviation Ra, the ten-point height of micro-roughness Rz, or the maximum height of profile Ry. The above evaluation parameters are obtained by sampling and measuring the thermosetting elastomer structure 20.
[0046] In some embodiments, the air guide surface 20a has a surface treated oxide layer, and the oxygen content of the surface treated oxide layer is greater than the oxygen content of the non-air guide surface 20b. That is, after the air guide surface 20a is processed, a surface treated oxide layer is formed on its surface, and the surface treatment process increases the oxygen content of the air guide surface 20a.
[0047] The surface treatment oxide layer is to chemically change the surface material of the wind-guiding surface 20a, change its molecular structure, and form more oxygen-containing groups. The oxygen-containing groups can change the properties of the wind-guiding surface 20a, make the molecular structure of its surface more densely arranged, and thus effectively reduce the roughness of the wind-guiding surface 20a.
[0048] In some embodiments, the oxygen content of the surface treated oxide layer is more than 1.5 times the oxygen content of the non-wind guiding surface 20b. In this way, the effect of reducing the surface roughness is better.
[0049] In some embodiments, the formation process of the surface treated oxide layer is accompanied by the separation of carbon atoms, so that the carbon content of the surface treated oxide layer is reduced, that is, the carbon content of the surface treated oxide layer is lower than the carbon content of the non-wind guiding surface. Specifically, in some embodiments, the carbon content of the surface treated oxide layer is 0.7 to 0.9 times the carbon content of the non-wind guiding surface 20b, including 0.7 times, 0.8 times and 0.9 times, etc.
[0050] Methods capable of detecting the difference in oxygen content between the air-guiding surface 20a and the non-air-guiding surface 20b include, but are not limited to: X-ray photoelectron spectroscopy (XPS) analysis method, which refers to the release of photoelectrons with various kinetic energies due to the photoelectric effect when the sample is irradiated with soft X-rays with an energy of hv (h is Planck's constant, v is the frequency of light), and obtaining information on the elemental composition and chemical bond state of the sample surface based on the kinetic energy and amount of the released photoelectrons.
[0051] In some embodiments, the surface treated oxide layer is obtained by photo-oxidation treatment of a local surface of the thermosetting elastomer structure 20. The photo-oxidation treatment refers to the surface of the thermosetting elastomer structure 20 combining new oxygen atoms to form a new molecular structure under the catalysis of light of a specific wavelength.
[0052] Exemplarily, in one embodiment, in an O3 (ozone) environment at 60 to 90°C (degrees Celsius), high-energy photons of a specific wavelength are used to induce the breaking of chemical bonds of molecules on the surface of the thermosetting elastomer structure 20 and combining with oxygen atoms in O3.
[0053] In some embodiments, the thermosetting elastomer structure 20 includes a rubber member. Of course, the thermosetting elastomer structure 20 may also be a member made of other materials that are both thermosetting and elastic.
[0054] The above-mentioned rubber parts refer to components made of rubber-like materials, which are also highly elastic polymer materials with reversible deformation and are elastic at room temperature. The spatial structure of rubber molecules is composed of multiple basic units (isoprene units) arranged and combined. There is a C=C double bond structure between each unit, so the rubber molecules have high flexibility and plasticity.
[0055] In some embodiments, the thermosetting elastomer structure 20 includes an EPDM rubber part, which is made of EPDM rubber material. EPDM rubber can also be called silicone rubber. EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated dienes, and is a type of ethylene-propylene rubber, represented by EPDM (Ethylene Propylene Diene Monomer). Because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, it has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance. In some embodiments, the EPDM rubber part is subjected to photo-oxidation treatment, and the characteristics of the surface treatment oxide layer obtained may include: first, the air guide surface 20a becomes a glass-like surface, and the sensitivity to dust and lint is reduced; second, the molecular structure of the air guide surface 20a after treatment is more densely arranged, and it is not easy to invade bacteria, preventing mold in a humid environment; third, the surface of the air guide surface 20a has a silky comfortable touch; fourth, the weather resistance and high temperature resistance of the thermosetting elastic part structure are improved.
[0056] For some examples, see Figure 2 and Figure 3 The clothes processing device comprises a drying tunnel assembly 200, a housing 300 and a thermosetting elastomer structure 20. The drying tunnel assembly 200 has an air outlet 200b, and the space inside the drying tunnel assembly 200 is a part of the air duct 200a, that is, the drying tunnel assembly 200 is located on the air flow loop.
[0057] See also Figure 3 The box body 300 has a front plate (not shown), and the front plate is provided with a clothing loading port (not shown). The thermosetting elastomer structure 20 includes a door seal ring 21, and the door seal ring 21 surrounds the clothing loading port, and the surrounding side of the door seal ring 21 has a return air port 21a, and the air supply port 200b is connected to the return air port 21a.
[0058] Exemplarily, an evaporator and a condenser are provided in the drying tunnel assembly 200. The evaporator is used to condense and dehumidify the airflow in the air duct 200a, and the condenser is used to heat the low-temperature dry airflow after condensation and dehumidification, and finally discharge it through the air outlet 200b.
[0059] The air in the drying tunnel assembly 200 flows into the laundry processing chamber 10a of the drum assembly 100 through the air supply port 200b and the air return port 21a. Figure 1The air guide surface 20a of the door seal ring 21 includes the circumferential inner surface of the door seal ring 21 and / or the inner surface of the return air port 21a. Its circumferential inner surface contacts the airflow in the clothes processing chamber 100a, and the inner surface of the return air port 21a contacts the airflow sent out by the drying duct assembly 200, both of which may carry impurities such as lint. These areas are processed to prevent them from absorbing impurities. Instead, other structures of the clothes processing device, such as a filter box or a filter screen, are used to collect impurities, so as to maintain the cleanliness of the air duct 200a as much as possible.
[0060] For some examples, see Figure 4 The drying tunnel assembly 200 of the clothes processing device includes an air inlet, and the drum assembly 100 includes an outer barrel 101, and the outer barrel 101 is provided with an air outlet (not shown). The thermosetting elastomer structure 20 includes a connecting pipe 22, and the connecting pipe 22 connects the air outlet and the air inlet.
[0061] The outer barrel 101 passes the gas in the laundry processing chamber 100a into the drying tunnel assembly 200 through the air outlet. In this embodiment, the air guide surface 20a of the connecting pipe 22 includes the circumferential inner surface of the connecting pipe 22 to reduce the accumulation of lint therein.
[0062] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.
[0063] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
