Description

Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular, relates to a clothing processing equipment and a heating module thereof. Background Art

[0002] Currently, most drum washing machines use heating tubes for washing and drying. From a heat transfer perspective, this is convection heat transfer and depends on the medium. Although the heating tube heating method is simple to control and low in cost, it also has disadvantages:

[0003] 1. The most direct problem caused by adding heat transfer medium is loss, which increases heat loss;

[0004] 2. Compared with other more advanced heating methods, the heating tube heats up more slowly;

[0005] 3. Washing and drying each use a set of heating systems, which cannot be shared and controlled uniformly.

[0006] To address these issues, patent application number CN99222051.3 discloses a drum washing machine that uses microwave heating and sterilization. The device comprises a drum washing machine, a microwave sterilization device, and a dehumidification device. The microwave sterilization device is mounted on both the outer and inner drums within the drum washing machine, while the dehumidification device is fixed to the rear of the drum washing machine. During the washing process, microwaves are transmitted into the washing drum via a microwave transmitting antenna, replacing the electric heating element to heat the water and dry the washed clothes.

[0007] However, the magnetron that generates microwaves in the above solution will generate heat during operation. Therefore, in order to prevent the temperature of the magnetron from exceeding the standard, the existing product is equipped with a heat dissipation fan for the magnetron. However, the heat dissipation of the magnetron by additionally providing a heat dissipation fan causes the product to occupy a large space and be costly.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a heating module for clothing processing equipment, which aims to use the air supply unit to provide an air source for the electric heating unit and to achieve the effect of heat dissipation of the microwave generating unit, thereby avoiding the additional setting of a heat dissipation system to occupy space and effectively utilizing the heat generated by the microwave generating unit.

[0029] Preferably, it further comprises a driving device for driving the first steering plate and the second steering plate to pivot.

[0030] Furthermore, the waveguide channel has a microwave inlet connected to the microwave generating unit and at least two microwave outlets for conducting microwaves;

[0031] The microwave outlets are respectively used to be connected to functional modules with different functions.

[0032] Furthermore, a switching unit is provided in the waveguide channel for selectively switching the microwaves entering from the microwave inlet to at least one of the microwave outlets;

[0033] Preferably, the switching unit includes a plurality of reflective plates.

[0058] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0060] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0061] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0062] like Figures 1 to 9As shown, the present invention provides a clothing treatment device and a heating module thereof. The clothing treatment device includes a housing 1, wherein a clothing treatment tub 2 for treating clothing is disposed within the housing 1. The clothing treatment tub 2 is connected to a water inlet assembly 3 and a drainage assembly 4. The water inlet assembly 3 introduces clean water into the clothing treatment tub 2, and the drainage assembly 4 discharges the dirty water in the clothing treatment tub 2.

[0063] The clothes processing device further includes a heating module, which can be used to provide required heat for various functional modules of the clothes processing device, such as heating water or air in the clothes processing tub 2, or thawing the water inlet component 3 or the drainage component 4.

[0064] The heating module of the clothing processing device of the present invention includes a microwave generating unit 5, an electric heating unit 12, and an air supply unit 13. The microwave generating unit 5 is used to provide microwaves for the functional modules of the clothing processing device; the electric heating unit 12 is arranged in an air guide channel 14 connected to the air supply unit 13 and is used to heat the air. The air supply unit 13 is arranged outside the microwave generating unit 5 and is used to dissipate heat for the microwave generating unit 5 and serve as an air power source for the electric heating unit 12.

[0065] In some embodiments of the present invention, the laundry processing device is a washer-dryer. The laundry processing tub 2 may include an inner tub and an outer tub. The microwave generating unit 5 and the electric heating unit 12 are connected to the inner tub. The housing 1 is provided with an exhaust device connected to the laundry processing tub 2 for discharging water vapor from the laundry processing tub 2. Preferably, the exhaust device includes an exhaust fan 19. An exhaust duct 20 is provided between the exhaust fan 19 and the laundry processing tub 2.

[0066] When washing begins, water first fills the outer drum to soak the clothes, then the inner drum begins to rotate and wash the clothes. When the heating function is activated, microwaves generated by the microwave generating unit 5 are introduced into the inner drum. The clothes and water inside the inner drum absorb the microwaves and generate heat, which acts as a heating device. Because the inner drum is also made of stainless steel, it does not absorb microwaves, but only reflects them. Furthermore, the elastic ribs 18 on the inner drum ensure a more random and uniform reflection of the microwaves, resulting in more uniform heating.

[0067] Before drying, some moisture remains in the clothes after being spun dry. Therefore, when microwave generating unit 5 is activated and microwaves are introduced into the inner drum, the remaining moisture in the clothes absorbs the microwave heat and evaporates into water vapor. At this time, exhaust fan 19 is turned on to directly exhaust the water vapor in the drum, similar to a direct-exhaust clothes dryer. During the washing and drying process, the thermal effect of the microwaves and the non-thermal sterilization effect play a role in sterilization.

[0068] After the microwave generator unit 5 has been operating for a period of time, it pauses and simultaneously activates the air supply unit 13 and the electric heating unit 12. At this point, the air supply unit 13 delivers the air, which has absorbed heat from the microwave generator unit 5, into the air guide 14. The air is heated by the electric heating unit 12 within the air guide 14 and then delivered to the laundry tub 2 to continue drying the laundry. The microwave generator unit 5 and the electric heating unit 12 can operate alternately.

[0069] Alternatively, microwave unit 5 can be used to heat the water in laundry tub 2 during the washing process. However, during the drying process, hot air generated by electric heating unit 12 is first used to evaporate any remaining moisture from the laundry, while simultaneously dissipating heat from microwave unit 5. Once the majority of the remaining moisture on the laundry has evaporated, if electric heating unit 12 is still used for drying, the drying efficiency will be very low. If electric heating unit 12 is then deactivated and microwave unit 5 activated, drying efficiency can be significantly improved, reducing energy consumption in the laundry processing apparatus.

[0070] In the above-described embodiment of the present invention, air supply unit 13 is positioned outside microwave generating unit 5, dissipating heat from microwave generating unit 5 while also effectively utilizing the heat generated during operation. Furthermore, air supply unit 13 not only dissipates heat from the microwave heat sink but also provides air power for electric heating unit 12. This embodiment of the present invention avoids the need for an additional heat dissipation system and the space occupied by a power unit, thus facilitating capacity expansion of the clothing processing equipment and reducing product costs.

[0071] In some embodiments of the present invention, the heating module further includes a waveguide channel 6, one end of which is in communication with the microwave generating unit 5 and the other end of which is in communication with the functional module of the clothing processing device, for transmitting the microwaves generated by the microwave generating unit 5 to the functional module. The waveguide channel 6 and the air guide channel 14 share a common housing and are at least partially isolated from each other. The electric heating unit 12 is disposed within the portion of the air guide channel 14 that is isolated from the waveguide channel 6.

[0072] In the above solution, the waveguide channel 6 between the microwave generating unit 5 and the functional module and the air guide channel 14 between the air supply unit 13 and the functional module are set to share a shell structure, which further optimizes the internal structure of the clothing processing device.

[0073] In a further solution, the entrance of the shell is connected to the microwave generating unit 5 and the air supply unit 13; a partition 15 is provided in the shell for isolating the air guide channel 14 and the waveguide channel 6, and one end of the partition 15 is provided at the entrance of the shell.

[0074] Optionally, the outlet of the shell can be connected to the clothes processing tub 2; or, the shell has multiple outlets, which are connected to the clothes processing tub 2 or the water inlet component 3 or the drainage component 4 respectively.

[0075] For example, the microwave generating unit 5 provides microwaves to the water inlet assembly 3 or the drainage assembly 4 for thawing, and the microwave generating unit 5 uses microwaves to heat the water in the laundry treatment tub 2, while the electric heating unit 12 is only connected to the laundry treatment tub 2 for providing hot air.

[0076] In detail, the partition 15 can be extended horizontally or longitudinally. The partition 15 divides part of the inner cavity of the housing into two parts, one part is the wind guide channel 14, and the other part is the waveguide channel 6.

[0077] Preferably, the starting point of the partition 15 is located at the entrance of the shell connected to the microwave generating unit 5 and the air supply unit 13; to avoid the electric heating unit 12 arranged in the air guide channel 14 absorbing or reflecting the microwaves and affecting the conduction direction of the microwaves.

[0078] In some embodiments of the present invention, one end of the partition 15 located at the entrance of the housing is provided with a flow guide device for guiding microwaves into the waveguide channel 6 or guiding air into the air guide channel 14 .

[0079] Specifically, the flow guiding device includes a first deflection plate 16 , which is pivotally connected to the partition 15 , and the first deflection plate 16 has a first position and a second position.

[0080] When the first deflection plate 16 is in the first position, the waveguide channel 6 is connected and the wind guide channel 14 is blocked.

[0081] When the first deflection plate 16 is in the second position, the waveguide channel 6 is cut off and the wind guide channel 14 is connected.

[0082] In a further solution, a second deflection plate 17 is provided at one end of the partition 15 away from the housing entrance, and the second deflection plate 17 is pivotally connected to the partition 15; the second deflection plate 17 has a first position and a second position.

[0083] When the second deflection plate 17 is in the first position, the second deflection plate 17 cooperates with the first deflection plate 16 to connect the waveguide channel 6 and block the air guide channel 14 .

[0084] When the second deflection plate 17 is in the second position, the second deflection plate 17 cooperates with the first deflection plate 16 to cut off the waveguide channel 6 and connect the air guide channel 14 .

[0085] Preferably, a driving device is further included for driving the first steering plate 16 and the second steering plate 17 to pivot.

[0086] In the above solution, a partition 15 is used in a set of shells to separate the inner cavity into an air guide channel 14 and a waveguide channel 6, and a guide device is used to guide microwaves or air into its own channel, which can further simplify the structure of the clothing processing equipment.

[0087] In addition, the electric heating unit 12 is arranged in the air guide channel 14, so that the electric heating unit 12 does not need to occupy additional space, further enabling the clothing processing device to achieve the purpose of expanding its capacity.

[0088] Detailed plans, such as Figure 2 and Figure 3 As shown, the first deflection plate 16 and the second deflection plate 17 both have a first position and a second position.

[0089] When the first deflection plate 16 and the second deflection plate 17 are in the first position, the microwaves generated by the microwave generating unit 5 enter the laundry processing tub 2 through the waveguide channel 6 .

[0090] When the first deflection plate 16 and the second deflection plate 17 are in the second position, the air supply unit 13 drives air into the laundry treatment tub 2 through the air guide channel 14 .

[0091] The first steering plate 16 and the second steering plate 17 are pivotally connected to the partition 15, and the two ends of the partition 15 are respectively connected to the edges of the first steering plate 16 and the second steering plate 17; the edges of the first steering plate 16 and the second steering plate 17 connected to the partition 15 constitute the pivot axis of their pivot.

[0092] The sizes of the first deflection plate 16 and the second deflection plate 17 of the present invention should match the inlet and outlet of the waveguide channel 6 and the wind guide channel 14 .

[0093] In some embodiments of the present invention, the laundry treatment tub 2 includes a washing tub and a water collecting device, and the outlet of the shell is connected to the washing tub.

[0094] In the above solution, the outlet of the housing is connected to the washing tub, and the microwaves generated by the microwave generating unit 5 and the heat generated by the electric heating unit 12 can directly enter the washing tub, thereby avoiding heat loss.

[0095] The washing tub is an inner tub without a dehydration hole. A drainage channel is provided on the inner tub to drain the water to the water collecting device, and then the water is discharged by the drainage assembly 4.

[0096] In some embodiments of the present invention, Figure 4As shown, a plurality of elastic ribs 18 for reflecting microwaves are provided on the inner wall of the laundry treatment tub 2; preferably, the elastic ribs 18 are provided extending along the axial direction of the laundry treatment tub 2. Preferably, the reflecting surface of the elastic ribs is a diamond-shaped surface.

[0097] In the above solution, by providing elastic ribs 18 with diamond-shaped surfaces on the inner wall of the clothes processing tub 2, the reflection of microwaves can be made more random and uniform, thereby achieving more uniform heating.

[0098] The clothes processing device of the present invention can adopt the following control method when performing the washing and care task:

[0099] S1, start the clothing processing equipment;

[0100] S2, determining whether the water inlet component 3 and / or the drainage component 4 is frozen, if so, starting the microwave generating unit 5 to perform defrosting, if not, proceeding to the next step;

[0101] S3, executing the washing procedure;

[0102] S4, determine whether the washing process is completed, if so, perform the drying process and proceed to the next step, if not, return to step S3;

[0103] S5, controlling the microwave generating unit 5 to start operation;

[0104] S6, determining whether the air humidity in the laundry processing tub 2 has dropped to a set value. If so, the microwave generating unit 5 is controlled to stop operating, and the electric heating unit 12 and the air supply unit 13 are controlled to start operating. If not, the process returns to step S5;

[0105] S7, determining whether the drying process is finished, if so, controlling the clothes processing device to standby, if not, returning to step S6.

[0106] In some embodiments of the present invention, Figure 4 As shown, the waveguide channel 6 has a microwave inlet connected to the microwave generating unit 5 and at least two microwave outlets for conducting microwaves; the microwave outlets are respectively used to connect to functional modules with different functions.

[0107] For example, a waveguide tube is provided between the microwave outlet of the waveguide channel 6 and the water inlet component 3 and / or the drainage component 4 .

[0108] Specifically, such as Figure 4As shown, when the water inlet assembly 3 and / or drainage assembly 4 of the laundry processing device is powered on, the change in the output voltage of the water inlet assembly 3 and / or drainage assembly 4 is detected. If the output voltage of the water inlet assembly 3 and / or drainage assembly 4 decreases by more than a predetermined value in the above steps, it indicates that the water inlet assembly 3 and / or drainage assembly 4 has frozen and needs to be defrosted. In this case, the microwaves emitted by the microwave generating unit 5 can be transmitted to the water inlet assembly 3 and / or drainage assembly 4 through the waveguide to perform defrosting.

[0109] In the above scheme, the microwave generating unit 5 can not only provide heat for the clothes processing barrel 2, but also be used to defrost the water inlet component 3 and / or the drainage component 4, reducing the number of parts of the clothes processing equipment and helping the clothes processing equipment to achieve the purpose of capacity expansion.

[0110] The microwave generator in the above solution can be composed of a magnetron.

[0111] In further solutions, such as Figures 4 to 8 As shown, the microwave inlet of the waveguide channel 6 is connected to the microwave generating unit 5, and the first microwave outlet 61 of the waveguide channel 6 is connected to the clothing processing tub 2; a first waveguide tube 7 is provided between the second microwave outlet 62 of the waveguide channel 6 and the water inlet component 3; and a second waveguide tube 8 is provided between the third microwave outlet 63 of the waveguide channel 6 and the drainage component 4.

[0112] In the above scheme, the microwaves generated by the microwave generating unit 5 are first introduced into the waveguide channel 6, and then the microwaves are transmitted to the position that actually needs to be heated through each microwave outlet of the waveguide channel 6 according to actual needs, so that the waveguide channel 6 only needs to be provided with a few microwave outlets, thereby simplifying the structure of the clothing processing equipment.

[0113] In addition, if Figure 4 As shown, the microwave generating unit 5 can be arranged on the right rear side of the outer cylinder, and the waveguide channel 6 is arranged above the outer cylinder along the axial extension of the outer cylinder. The first waveguide tube 7 and the second waveguide tube 8 are led out from the waveguide channel 6, so that they can utilize the space between the outer cylinder and the box body 1, thereby improving the space utilization rate inside the box body 1 of the clothing processing equipment.

[0114] In a further solution, a switching unit is provided in the waveguide channel 6 for selectively switching the microwaves entering from the microwave inlet to at least one of the microwave outlets.

[0115] Preferably, the switching unit includes a plurality of reflecting plates, and the microwaves emitted by the microwave generating unit 5 are output from one of the microwave outlets under the interaction of the plurality of reflecting plates.

[0116] In detail, a plurality of reflecting plates are provided in the waveguide channel 6 , and the microwaves emitted by the microwave generating unit 5 enter the clothing processing tub 2 or the first waveguide tube 7 or the second waveguide tube 8 under the interaction of the plurality of reflecting plates.

[0117] In the above solution, the reflector can reflect microwaves, and the conduction direction of the microwaves is controlled under the combined reflection effect of several reflectors. The structure is simple and easy to implement.

[0118] Specifically, such as Figures 5 to 8 As shown, a first reflecting plate 9 , a second reflecting plate 10 and a third reflecting plate 11 are provided in the waveguide channel 6 .

[0119] The angles of the first reflective plate 9 and the second reflective plate 10 remain unchanged; the third reflective plate 11 has a first angle, a second angle and a third angle.

[0120] When the third reflecting plate 11 is at the first angle, the microwaves emitted by the microwave generating unit 5 are reflected by the first reflecting plate 9 and output from the first microwave outlet 61 .

[0121] When the third reflecting plate 11 is at the second angle, the microwaves emitted by the microwave generating unit 5 are reflected by the first reflecting plate 9 and the third reflecting plate 11 and output from the second microwave outlet 62 .

[0122] When the third reflector 11 is at the third angle, the microwaves emitted by the microwave generating unit 5 enter the third microwave outlet 63 under the joint action of the first reflector 9 , the second reflector 10 , and the third reflector 11 .

[0123] In an optional solution, the first reflector 9, the second reflector 10, and the third reflector 11 are disposed on the bottom wall of the housing; the third reflector 11 is pivotally connected to the bottom wall of the housing. Preferably, a driving unit for driving the third reflector 11 to pivot is connected to the pivot shaft of the third reflector 11.

[0124] The microwave generating unit 5 is arranged in the installation shell. The installation shell of the microwave generating unit 5 is connected to the shells of the waveguide channel and the air guide channel to form a volute-like structure. The connection between the installation shell of the microwave generating unit 5 and the shells of the waveguide channel and the air guide channel forms a throat.

[0125] A first reflector 9 is disposed on the side wall of the housing, at a position at the downstream end of the throat portion facing the microwave outlet of the microwave generating unit 5. A second reflector 10 is disposed on the same side wall of the housing as the first reflector 9. A third reflector 11 is disposed on the bottom wall of the waveguide channel 6. The third reflector 11 is controllably shiftable between a first angle, a second angle, and a third angle under the action of a drive unit.

[0126] like Figure 6 As shown, the angles of the first reflector 9 and the second reflector 10 remain unchanged. The angle between the first reflector 9 and the side wall of the housing is such that microwaves can enter the laundry tub 2 through reflection from the first reflector 9. In this case, the second reflector 10 does not reflect microwaves, and the third reflector 11 is at the first angle and also does not reflect microwaves, allowing microwaves to enter the laundry tub 2 smoothly.

[0127] like Figure 7 As shown, when the third reflector 11 is controlled to be at the second angle, the microwaves emitted by the microwave generating unit 5 are reflected by the first reflector 9 to the third reflector 11, and then reflected by the third reflector 11 to the second microwave outlet 62 of the waveguide channel 6 to enter the first waveguide tube 7, and then transmitted to the water inlet component 3 to provide heat for the water inlet component 3.

[0128] like Figure 8 As shown, when the third reflecting plate 11 is controlled to be at a third angle, the microwaves emitted by the microwave generating unit 5 are reflected by the first reflecting plate 9 to the third reflecting plate 11, and then reflected by the third reflecting plate 11 to the second reflecting plate 10, and finally reflected by the second reflecting plate 10 to the third microwave outlet 63 of the waveguide channel 6 to enter the second waveguide tube 8, and then transmitted to the drainage component 4 to provide heat for the drainage component 4.

[0129] In the above scheme, the angles of the first reflector 9, the second reflector 10 and the third reflector 11 can be specifically set according to the relative position relationship of the waveguide channel 6, the first waveguide tube 7 and the second waveguide tube 8. The present invention does not limit this. As long as the above scheme can be implemented, it is within the protection scope of the present invention.

[0130] The present invention is attached Figures 6 to 8 The illustrated arrangement structure and angles of the first, second, and third reflectors 9, 10, 11 are merely one embodiment of an embodiment capable of utilizing reflectors to control the direction of microwave transmission. It will be appreciated that various combinations of the arrangement structures and angles of the first, second, and third reflectors 9, 10, 11 are possible, and any solution capable of controlling the microwaves to be output from the first, second, and third microwave outlets 61, 62, 63, respectively, falls within the scope of protection of the present invention.

[0131] In some embodiments of the present invention, the housing includes a body and a cover that are interlocked and connected, the first reflector 9 and the second reflector 10 are formed by the side walls of the body; the third reflector 11 is pivotally connected to the bottom wall of the body.

[0132] Preferably, the pivot shaft of the third reflective plate 11 is connected to a driving unit for driving the third reflective plate 11 to pivot.

[0133] In the above solution, the first reflective plate 9 and the second reflective plate 10 may be formed by the side walls of the body, that is, the first reflective plate 9 and the second reflective plate 10 are formed integrally with the housing.

[0134] In some embodiments of the present invention, the reflective surfaces of the first reflective plate 9 , the second reflective plate 10 , and the third reflective plate 11 are metal planar structures.

[0135] In the above scheme, in order to better reflect microwaves, the present invention sets the reflecting surfaces of the first reflecting plate 9, the second reflecting plate 10 and the third reflecting plate 11 to metal plane structures to reduce microwave propagation loss in the air.

[0136] Microwaves pass through glass, plastic, and porcelain without being absorbed. Water, for example, absorbs microwaves and heats itself. Metal, on the other hand, reflects microwaves.

[0137] Therefore, the waveguide channel 6, the first waveguide tube 7 and the second waveguide tube 8 of the present invention are also made of metal materials.
