Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular, relates to an outer drum of clothing processing equipment and the clothing processing equipment. Background Art

[0002] Some existing clothing processing equipment heats the washing water by setting a heating tube on the outer drum during the washing process. This process heats up slowly and takes a long time to wash. During the drying process, an external drying fan is used to blow hot air to heat the clothes. This has low drying efficiency, high energy consumption and long drying time.

[0003] Therefore, currently another part of the clothes processing equipment heats the washing water by electromagnetic induction heating, namely, electromagnetic heating, by arranging an electromagnetic heating device on a partial area outside the side wall of the outer drum.

[0004] The principle of electromagnetic heating is to generate an alternating magnetic field through a power supply. When an iron-containing container is placed in the alternating magnetic field, the surface of the container cuts the alternating magnetic field lines and generates a current vortex in the metal part at the bottom of the container. The current vortex causes the carriers at the bottom of the container to move irregularly at high speed. The carriers and atoms collide and rub against each other to generate heat, thereby heating the object. Because the iron-containing container itself generates heat, the heat conversion rate is particularly high, up to 95%. Therefore, the washing machine uses an electromagnetic heating device to heat the washing water, which has a higher heating efficiency.

[0005] However, the heating area of ​​the outer drum of the existing electromagnetic heating device is too small, so that the inner drum of the clothes processing device is heated unevenly and cannot be used in the drying process of the clothes processing device.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an outer drum of a clothing processing device and a clothing processing device, which uniformly and fully heats the washing water and drying air by utilizing an electromagnetic heating coil embedded in the side wall of the outer drum of the clothing processing device.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] The present invention provides an outer drum of a clothes processing device, comprising:

[0010] An electromagnetic heating coil is wound around the side wall of the outer cylinder. The electromagnetic heating coil is embedded in the side wall of the outer cylinder. The electromagnetic heating coil is used to generate an alternating magnetic field.

[0011] The present invention winds an electromagnetic heating coil around and embeds it into the side wall of the outer drum of the clothing processing device, so that the electromagnetic heating coil generates an alternating magnetic field, so that the iron-containing container in the outer drum generates current vortices and electrons move in holes, thereby generating uniform and sufficient heat.

[0012] A further solution of the present invention is that a protruding clamping portion is provided on the outer surface of the side wall of the outer cylinder, and the clamping portion has a cavity, and the wire forming the electromagnetic heating coil is embedded in the cavity of the clamping portion.

[0013] In the above solution, the electromagnetic heating coil is stably and firmly embedded in the outer surface of the side wall of the outer cylinder through the clamping portion on the outer surface of the side wall of the outer cylinder.

[0014] A further solution of the present invention is that the electromagnetic heating coil is spirally wound along the side wall of the outer cylinder for a plurality of turns, and the clamping parts are arranged on the side wall of the outer cylinder at intervals along the spiral winding direction of the electromagnetic heating coil;

[0015] A heat dissipation channel is formed between two adjacent clamping parts in the axial direction of the outer tube, which first expands and then contracts along the protruding direction of the clamping parts.

[0016] In the above scheme, a heat dissipation channel that first expands and then contracts along the protruding direction of the clamping portion is formed through the interval between two adjacent clamping portions in the axial direction of the outer cylinder, so that when the electromagnetic heating coil wound on the side wall of the outer cylinder conducts heat to the outer cylinder through the clamping portion, the heat dissipation effect of the clamping portion is better.

[0017] A further solution of the present invention is that the cavity of the clamping portion has an opening, and the electromagnetic heating coil is installed inside the cavity through the opening.

[0018] In the above solution, the electromagnetic heating coil can be more conveniently installed in the cavity through the opening of the cavity of the clamping portion, and the electromagnetic heating coil can be more conveniently disassembled.

[0019] A further solution of the present invention is that the opening of the cavity is arranged on a side of the cavity away from the side wall of the outer cylinder, and the distance of the opening is smaller than the cross-sectional diameter of the wire of the electromagnetic heating coil.

[0020] In the above solution, the distance of the opening is smaller than the cross-sectional diameter of the wire of the electromagnetic heating coil, so that the electromagnetic heating coil can be detachably installed in the cavity.

[0021] A further solution of the present invention is that a relatively protruding blocking portion is provided on the side wall of the clamping portion at the opening.

[0022] In the above solution, a relatively protruding blocking portion is provided at the opening, so that the electromagnetic heating coil can be more firmly installed in the cavity.

[0023] A further solution of the present invention is that the electromagnetic heating coil is embedded in the side wall of the outer cylinder.

[0024] In the above solution, the electromagnetic heating coil is embedded in the side wall of the outer cylinder, so that it can adapt to a more complex outer cylinder side wall structure without changing the existing outer cylinder structure shape.

[0025] A further solution of the present invention is that the electromagnetic heating coil is disposed inside the side wall of the outer cylinder by injection molding and is completely covered by the side wall.

[0026] In the above solution, the electromagnetic heating coil is disposed inside the side wall of the outer cylinder by injection molding and is completely covered by the side wall, thereby reducing the production cost of embedding the electromagnetic heating coil inside the side wall of the outer cylinder.

[0027] A further solution of the present invention is that the electromagnetic heating coil includes a wiring terminal, and the wiring terminal passes through the outer surface of the side wall of the outer cylinder.

[0028] In the above solution, the electromagnetic heating coil including the terminal passes through the outer surface of the side wall of the outer cylinder, thereby solving the power supply and control problems of embedding the electromagnetic heating coil inside the side wall of the outer cylinder.

[0029] The present invention further provides a clothes processing device, wherein the clothes processing device is provided with the outer drum of the clothes processing device mentioned above.

[0030] In the above scheme, the heating tube and the drying fan of the clothing processing equipment are eliminated through the outer drum of the clothing processing equipment, so that the washing water and the drying air can be heated through one device, which greatly saves the production cost, reduces the washing energy consumption and the drying energy consumption of the clothing processing equipment, and shortens the time required for the clothing processing equipment to heat the washing water and complete the drying, thereby improving the user experience.

[0031] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0032] 1. The electromagnetic heating coil is wound around and embedded in the side wall of the outer drum of the clothing treatment device, so that the electromagnetic heating coil generates an alternating magnetic field, so that the iron-containing container in the outer drum generates current vortices and electrons move in holes, thereby generating uniform and sufficient heat;

[0033] 2. The electromagnetic heating coil is stably and firmly embedded in the outer surface of the side wall of the outer cylinder through the clamping part on the outer surface of the side wall of the outer cylinder, thereby reducing the production cost of the outer cylinder;

[0034] 3. The electromagnetic heating coil is embedded in the side wall of the outer cylinder, so that it can adapt to the more complex side wall structure of the outer cylinder without changing the existing outer cylinder structure;

[0035] 4. The outer drum of the clothing processing equipment eliminates the heating tube and the drying fan of the clothing processing equipment, so that the washing water and the drying air can be heated by one device, which greatly saves the production cost, reduces the washing energy consumption and the drying energy consumption of the clothing processing equipment, and shortens the time required for the clothing processing equipment to heat the washing water and complete the drying, thereby improving the user experience.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] like Figures 1 to 4 As shown, the present invention provides an outer drum of a clothes processing device and a clothes processing device, which uniformly and fully heats washing water and drying air by utilizing an electromagnetic heating coil 122 embedded in the side wall of the outer drum 1 of the clothes processing device.

[0048] Embodiment 1

[0049] like Figure 1 , 2 As shown in Figure 3, this embodiment provides an outer drum 1 of a clothes processing device, comprising:

[0050] An electromagnetic heating coil 122 is wound around the side wall of the outer cylinder 1 . The electromagnetic heating coil 122 is embedded in the side wall of the outer cylinder 1 . The electromagnetic heating coil 122 is used to generate an alternating magnetic field.

[0051] The principle of electromagnetic heating is to generate an alternating magnetic field through a power supply. When an iron-containing container is placed in the alternating magnetic field, the surface of the container cuts the alternating magnetic field lines and generates a current vortex at the metal part at the bottom of the container. The current vortex causes the carriers at the bottom of the container to move irregularly at high speed, and the carriers and atoms collide and rub against each other to generate heat, thereby achieving the effect of heating the object. Because the iron-containing container itself generates heat, the heat conversion rate is particularly high, up to 95%. Therefore, the outer cylinder 1 of this embodiment has the advantages of fast heating speed, fast temperature rise speed, non-contact heating method, easy operation, safety, low surface oxidation degree of the heated object, high heating efficiency, energy saving, etc.

[0052] In a specific application of this embodiment, the clothing processing device is a drum washing machine, the side wall of the inner drum of which is made of stainless steel. The side wall of the inner drum cuts the alternating magnetic lines of force in the alternating magnetic field to generate current vortices, which generates heat in the inner drum and inside the inner drum. Because the heat is generated from the electromagnetic heating coil 122 that is a complete circle around the side wall of the outer drum 1, the heat is superimposed and diffused, so that the inner drum is heated evenly and fully.

[0053] Therefore, by winding the electromagnetic heating coil 122 around and embedding it into the side wall of the outer drum 1 of the clothing processing device, the electromagnetic heating coil 122 generates an alternating magnetic field, so that the iron-containing container in the outer drum 1 generates current vortices and electrons move in holes, thereby generating uniform and sufficient heat.

[0054] In this embodiment, a protruding clamping portion 121 is provided on the outer surface of the side wall of the outer cylinder 1 . The clamping portion 121 has a cavity, and the wire forming the electromagnetic heating coil 122 is embedded in the cavity of the clamping portion 121 .

[0055] In a specific application of this embodiment, Figure 2 As shown, a plurality of outer cylinder fixing members 13, outer cylinder connecting members 14 and reinforcing rib fixing members 15 are arranged on the outer side of the side wall of the outer cylinder 1. The outer cylinder fixing member 13 is used to connect the outer cylinder 1 with the housing of the clothing processing device, the outer cylinder connecting member 14 is used to fix the bottom and the side wall of the outer cylinder 1, and the reinforcing rib fixing member 15 is used to strengthen the structural stability of the outer cylinder 1 made of plastic at the bottom of the outer cylinder 1. Specifically, the clamping portion 121 is arranged on the outer cylinder fixing member 13, the outer cylinder connecting member 14, the reinforcing rib fixing member 15 and the side wall of the outer cylinder 1, so that the electromagnetic heating coil 122 is closely attached to the surface of the outer cylinder fixing member 13, the outer cylinder connecting member 14, the reinforcing rib fixing member 15 and the side wall of the outer cylinder 1, and is fixed to the outer surface of the side wall of the outer cylinder 1.

[0056] In a specific application of this embodiment, the outer cylinder 1 is made of a mixed plastic material of polypropylene (PP) and glass fiber.

[0057] The electromagnetic heating coil 122 is stably and firmly embedded in the outer surface of the side wall of the outer tube 1 through the clamping portion 121 on the outer surface of the side wall of the outer tube 1 .

[0058] In this embodiment, the electromagnetic heating coil 122 is spirally wound along the side wall of the outer cylinder 1 for multiple turns, and the clamping portion 121 is arranged on the side wall of the outer cylinder 1 along the spiral winding direction of the electromagnetic heating coil 122 at intervals.

[0059] A heat dissipation channel is formed between two adjacent clamping portions 121 in the axial direction of the outer cylinder 1 , which expands first and then contracts along the protruding direction of the clamping portions 121 .

[0060] Specifically, Figure 3 As shown, the clamping parts 121 are closely distributed at a certain distance in the axial direction of the inner cylinder and are flush in the same axial direction.

[0061] Specifically, Figure 3 As shown, the clamping part 121 is made of iron or carbon steel, and the outer surface of the clamping part 121 is covered with a heat-insulating material, so that the clamping part 121 can easily dissipate heat to the surroundings. In detail, because the principle of induction heating is to use a high-frequency alternating magnetic field to generate a current vortex, resistance heating is generated in the iron-containing container where the current vortex is located, so that the iron-containing container is heated. Therefore, a magnetic field will interact with the iron-containing container around the induction heating coil, resulting in eddy currents inside the iron-containing container, and then resistance heating will occur, so that the conductors around the coil including the outer tube 1 and the clamping part 121 will also heat up.

[0062] Therefore, a heat dissipation channel that first expands and then contracts along the protruding direction of the clamping portion 121 is formed through the interval between two adjacent clamping portions 121 in the axial direction of the outer cylinder 1, so that when the electromagnetic heating coil 122 wound on the side wall of the outer cylinder 1 conducts heat to the outer cylinder 1 through the clamping portion 121, the heat dissipation effect of the clamping portion 121 is better.

[0063] In this embodiment, the cavity of the clamping portion 121 has an opening, and the electromagnetic heating coil 122 is installed in the cavity through the opening.

[0064] Through the opening of the cavity of the clamping portion 121, the electromagnetic heating coil 122 can be more conveniently installed in the cavity, and the electromagnetic heating coil 122 can be more conveniently disassembled.

[0065] Specifically, Figure 3 As shown, the cavity is a cylindrical cavity surrounding the electromagnetic heating coil 122 .

[0066] In this embodiment, the opening of the cavity is arranged on a side of the cavity away from the side wall of the outer cylinder 1 , and the distance of the opening is smaller than the cross-sectional diameter of the wire of the electromagnetic heating coil 122 .

[0067] The distance through the opening is smaller than the cross-sectional diameter of the wire of the electromagnetic heating coil 122 , so that the electromagnetic heating coil 122 can be more conveniently installed in the cavity through the opening.

[0068] In this embodiment, a relatively protruding blocking portion 1211 is disposed on the side wall of the clamping portion 121 at the opening.

[0069] By providing a relatively protruding blocking portion 1211 at the opening, the electromagnetic heating coil 122 can be more firmly installed in the cavity.

[0070] Specifically, Figure 1 , 2 As shown in FIG. 3 , the clamping portion 121 is disposed at the bottom of the side wall of the outer drum 1 of the laundry processing device. Figure 1 Can be seen as Figure 2 The cross-sectional view is a planar view of the outer cylinder 1 along the symmetry axis passing through the terminal 11 vertically. Figure 3 As shown, the clamping portion 121 is arranged on the lower side of the terminal 11 of the side wall of the outer drum 1 of the clothing processing device, close to the bottom surface of the outer drum 1, so that the electromagnetic heating coil 122 is wrapped around the outer drum 1 for at least 6 turns.

[0071] Specifically, the connection terminal 11 is used to connect the external induction power supply and controller of the outer cylinder 1 to the electromagnetic heating coil 122, so as to connect the electromagnetic heating coil 122 to high-frequency alternating current and control its heating effect.

[0072] In a specific application of this embodiment, the outer cylinder 1 in this embodiment is only the base of the outer cylinder 1, and the base and the side wall of the outer cylinder 1 are manufactured separately, further reducing the production cost of embedding the electromagnetic heating coil 122 on the surface of the side wall of the outer cylinder 1.

[0073] In this embodiment, a heat insulation structure is provided on the inner side of the side wall of the outer cylinder 1, and the heat insulation structure is used to lock the heat energy inside the outer cylinder 1, while keeping the electromagnetic heating coil 122 outside the outer cylinder 1 at a relatively low temperature. The stability of the inductance of the electromagnetic induction coil of the heat insulation structure also significantly improves the continuous stability of the heating temperature, improves the heating effect, and reduces power consumption.

[0074] In a specific application of this embodiment, the heat insulating structure is a heat insulating layer, which is cast into a mold of the outer cylinder 1 to form a heat insulating layer integrated with the outer cylinder 1 .

[0075] In another specific application of this embodiment, the heat insulation structure may also be a heat insulation coating, and the heat insulation coating is a coating with heat insulation and insulation functions formed by spraying the inner surface of the outer cylinder 1 .

[0076] In this embodiment, the electromagnetic heating coil 122 is wound around and embedded in the side wall of the outer drum 1 of the clothing processing device, so that the electromagnetic heating coil 122 generates an alternating magnetic field, so that the iron-containing container in the outer drum 1 generates current vortices and electrons move in holes, thereby generating uniform and sufficient heat; through the clamping part 121 on the outer surface of the side wall of the outer drum 1, the electromagnetic heating coil 122 is stably and firmly embedded in the outer surface of the side wall of the outer drum 1, thereby reducing the production cost of the outer drum 1.

[0077] Embodiment 2

[0078] like Figure 1 , 2 As shown in Figure 3, this embodiment provides an outer drum 1 of a clothing processing device. The difference between this embodiment and the first embodiment is that a clamping portion 121 is provided on the outer drum 1, and the cavity of the clamping portion 121 surrounds the electromagnetic heating coil 122 along the side wall of the outer drum 1, and the clamping portion 121 surrounds the side wall of the outer drum 1 for at least one circle.

[0079] Specifically, Figure 1 , 2 As shown in FIG. 3 , the clamping portion 121 is disposed around the side wall of the outer drum 1 of the laundry processing device near the bottom end of the side wall. Figure 1 Can be seen as Figure 2 The cross-sectional view is a planar view of the outer cylinder 1 along the symmetry axis passing through the terminal 11 vertically. Figure 3 As shown, the clamping portion 121 is arranged on the lower side of the terminal 11 of the side wall of the outer drum 1 of the clothing processing device, surrounding the outer drum 1 to the bottom surface close to the outer drum 1, and the cavity of the clamping portion 121 completely surrounds the electromagnetic heating coil 122 from one end to the other end, and the electromagnetic heating coil 122 is wrapped around the outer drum 1 for at least 6 turns.

[0080] In this embodiment, a clamping portion 121 is used to completely surround the electromagnetic heating coil 122 from one end to the other end of the cavity, thereby reducing the cost of setting the clamping portion 121 on the outer tube 1 and further allowing the electromagnetic heating coil 122 to be stably and firmly embedded in the outer surface of the side wall of the outer tube 1.

[0081] Embodiment 3

[0082] like Figure 1 , 2 As shown in FIG. 4 , this embodiment provides an outer drum 1 of a clothing processing device. The difference between this embodiment and the first and second embodiments is that the electromagnetic heating coil 122 is embedded in the side wall of the outer drum 1 .

[0083] Specifically, Figure 2 As shown, a plurality of outer cylinder fixing members 13, outer cylinder connecting members 14 and reinforcing rib fixing members 15 are arranged on the outer side of the side wall of the outer cylinder 1. The outer cylinder fixing members 13 are used to connect the outer cylinder 1 and the shell of the clothing processing device, the outer cylinder connecting members 14 are used to fix the bottom and the side wall of the outer cylinder 1, and the reinforcing rib fixing members 15 are used to strengthen the structural stability of the outer cylinder 1 made of plastic at the bottom of the outer cylinder 1.

[0084] In a specific application of this embodiment, the electromagnetic heating coil 122 passes through the outer cylinder fixing piece 13 , the outer cylinder connecting piece 14 and the reinforcing rib fixing piece 15 in the side wall of the outer cylinder 1 .

[0085] In a specific application of this embodiment, the electromagnetic heating coil 122 passes through the side wall of the outer cylinder 1 or is bent toward the inner side of the side wall of the outer cylinder 1 to pass through the outer cylinder fixing piece 13 , the outer cylinder connecting piece 14 and the reinforcing rib fixing piece 15 .

[0086] Therefore, when the electromagnetic heating coil 122 is embedded in the side wall of the outer tube 1 , it can adapt to a more complex side wall structure of the outer tube 1 without changing the existing structural appearance of the outer tube 1 .

[0087] In this embodiment, the electromagnetic heating coil 122 is disposed inside the side wall of the outer cylinder 1 by injection molding and is completely covered by the side wall.

[0088] In a specific application of this embodiment, the outer cylinder 1 is made of a mixed plastic material of polypropylene (PP) and glass fiber, making it easy to set the electromagnetic heating coil 122 inside the side wall of the outer cylinder 1 by injection molding.

[0089] The electromagnetic heating coil 122 is disposed inside the side wall of the outer cylinder 1 by injection molding and is completely covered by the side wall, thereby reducing the production cost of embedding the electromagnetic heating coil 122 inside the side wall of the outer cylinder 1 .

[0090] In this embodiment, the electromagnetic heating coil 122 includes a terminal 11 , and the terminal 11 passes through the outer surface of the side wall of the outer tube 1 .

[0091] The electromagnetic heating coil 122 including the terminal 11 passes through the outer surface of the side wall of the outer tube 1, thereby solving the power supply and control problems of embedding the electromagnetic heating coil 122 inside the side wall of the outer tube 1.

[0092] Specifically, the connection terminal 11 is used to connect the external induction power supply and controller of the outer cylinder 1 to the electromagnetic heating coil 122, so as to connect the electromagnetic heating coil 122 to high-frequency alternating current and control its heating effect.

[0093] In this embodiment, Figure 1 , 2 As shown in FIG. 4 , the electromagnetic heating coil 122 is disposed at the bottom of the side wall of the outer drum 1 of the laundry processing device. Figure 1 Can be seen as Figure 2 The cross-sectional view is a planar view of the outer cylinder 1 along the symmetry axis passing through the terminal 11 vertically. Figure 4 As shown, the clamping portion 121 is disposed on the lower side of the connection terminal 11 of the side wall of the outer drum 1 of the laundry processing device, and the electromagnetic heating coil 122 is wound around the outer drum 1 for at least 6 turns.

[0094] Embodiment 4

[0095] This embodiment provides a clothes processing device, which is provided with the outer drum 1 of the clothes processing device as described in the first to third embodiments.

[0096] In a specific application of this embodiment, the clothing processing device is a drum washing machine, the side wall of the inner drum of the clothing processing device is made of stainless steel, and the outer drum 1 is made of a mixed plastic material of polypropylene (PP) and glass fiber.

[0097] In this embodiment, the outer drum 1 of the clothing processing device is used to eliminate the heating tube and the drying fan of the clothing processing device, so that the washing water and the drying air can be heated by one device, which greatly saves the production cost, reduces the washing energy consumption and the drying energy consumption of the clothing processing device, and shortens the time required for the clothing processing device to heat the washing water and complete the drying, thereby improving the user experience.
