Detailed Implementation

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] like Figures 1-12 As shown, a washing machine includes a housing 1, an outer drum 2 disposed inside the housing 1, a support 3 disposed at the lower part of the outer drum 2, and a heating assembly 4 disposed on the support 3. The heating assembly 4 includes a heater 41 and a protective frame 42. The heater 41 is provided with a heating base 410. The protective frame 42 includes a detachably connected fixing frame 421 and a base 422. The heating base 410 is located between the fixing frame 421 and the base 422. The support 3 and the protective frame 42 cooperate to fix the heater 41. A sealing ring 5 is provided between the fixing frame 421 and the heating base 410 for waterproof sealing between the heater 41 and the protective frame 42. The heater 41 is located inside the outer drum 2 and is used to heat the washing water inside the outer drum 2.

[0037] The washing machine described in this application uses a bracket 3 at the bottom of the outer drum 2 to fix the heater 41 in cooperation with the protective frame 42. The overall volume of the heating component 4 is small, which reduces the space occupied by the outer drum 2, facilitates the miniaturization design of the washing machine, reduces indoor space occupation, lowers transportation and storage costs, and improves the applicability of the product in space-constrained scenarios.

[0038] On the other hand, this structure provides a solid support for the heater 41, ensuring its stability during operation and reducing potential malfunctions caused by shaking or displacement. The sealing ring 5 between the fixing frame 421 and the heating base 410 can effectively prevent water leakage from the heating component 4, avoid safety hazards such as short circuits, and extend the service life of the equipment. The fixing frame 421 and the base 422 are designed to be detachably connected, which facilitates disassembly and replacement when the heater 41 malfunctions or needs maintenance.

[0039] Preferably, the bracket 3 is made of heat-resistant and flame-retardant materials.

[0040] As a preferred example of this application, the bracket 3 is disposed near the edge of the outer cylinder 2, the outer cylinder 2 is provided with a circulation pipe, and the heater 41 is disposed on the circulation pipe for heating the washing water in the outer cylinder 2.

[0041] Specifically, the support 3 is arranged close to the edge of the outer cylinder 2, reasonably utilizes the space around the outer cylinder 2, makes the structure layout inside the washing machine more compact, conforms to the development trend of small household appliances, and sets the heater 41 on the circulating pipeline. The washing water in the outer cylinder 2 can continuously pass through the heater 41 in the circulating process. Compared with direct heating in the outer cylinder, the circulating heating mode can make the washing water more fully absorb heat, reduce the heating time, improve the heating efficiency, thereby improving the washing effect and meeting the user's demand for rapid washing.

[0042] As a preferred example of the present application, the support 3 is provided with a first avoiding hole 301, the fixing frame 421 is provided with a second avoiding hole 4212, the sealing ring 5 is provided with a third avoiding hole 503, and the heater 41 extends into the outer cylinder 2 through the third avoiding hole 503, the second avoiding hole 4212 and the first avoiding hole 301 in sequence.

[0043] Specifically, such an arrangement facilitates the installation of the heater 41, reduces the installation difficulty, improves the installation efficiency, and also facilitates the disassembly and reinstallation of the heater 41 during subsequent maintenance and repair.

[0044] As a preferred example of the present application, the fixing frame 421 includes a fixing plate 4213, the edge of the fixing plate 4213 is provided with a surrounding plate 4214, the fixing plate 4213 is provided with a groove 4215, the second avoiding hole 4212 is located in the groove 4215, and the sealing ring 5 is installed in the groove 4215 through the second avoiding hole 4212.

[0045] Specifically, the groove 4215 and the second avoiding hole 4212 provide a specific position and installation path for the installation of the sealing ring 5. The installer can conveniently and accurately install the sealing ring 5 into the groove 4215 through the second avoiding hole 4212, which reduces the installation difficulty, improves the installation efficiency, facilitates the replacement of the sealing ring 5 during subsequent maintenance, and also plays a limiting role on the sealing ring 5, making the installation more stable and not easy to shift. It can ensure that the sealing ring 5 is tightly attached to the heater 41 and the fixing frame 421, further enhancing the waterproof sealing effect.

[0046] As a preferred example of the present application, the upper end of the sealing ring 5 is provided with a convex ring 51 protruding upward, the convex ring 51 extends into the second avoiding hole 4212, the upper end of the convex ring 51 abuts against the support 3, the outer side wall of the convex ring 51 abuts against the side wall of the second avoiding hole 4212, and a gap is left between the inner side wall of the convex ring 51 and the heater 41.

[0047] Specifically, the structure design makes the installation of the sealing ring 5 more convenient. The convex ring 51 can quickly and accurately extend into the second avoiding hole 4212 during installation. The sealing ring 5 is also easy to disassemble during maintenance or replacement. Meanwhile, a gap is left between the inner side wall of the convex ring 51 and the heater 41, which can prevent the convex ring 51 from being deformed and damaged by the heater 41, thereby prolonging the service life of the sealing ring 5.

[0048] As a preferred example of the present application, the upper end of the convex ring 51 is provided with a first flange 521 abutting against the bracket 3 for waterproof sealing between the sealing ring 5 and the bracket 3. The lower end of the sealing ring 5 is provided with adjacent second and third flanges 522 and 523, respectively, abutting against the heating seat 410 for waterproof sealing between the sealing ring 5 and the heating seat 410.

[0049] Specifically, the design forms a multi-layer waterproof sealing structure, greatly enhancing the waterproof performance of the sealing ring 5, which can effectively prevent the heating assembly 4 from leaking water and causing electrical failure, thereby ensuring the safe and stable operation of the washing machine.

[0050] As a preferred example of the present application, the surrounding plate 4214 is provided with buckles 6 for clamping and fixing with the side wall of the base 422.

[0051] Specifically, the clamping mode of the buckle 6 is simple to operate without the need for additional tools. The installer only needs to align the buckle 6 on the surrounding plate 4214 with the side wall of the base 422 for clamping, which can quickly complete the connection of the fixing frame 421 and the base 422. Compared with the bolt connection mode, the assembly time is greatly shortened, and the production efficiency is improved.

[0052] Preferably, a plurality of buckles 6 are arranged on the surrounding plate 4214.

[0053] As a preferred example of the present application, the fixing plate 4213 is provided with a through slot 7 on the inner side of the buckle 6. The through slot 7 is used to facilitate the elastic deformation of the surrounding plate 4214 when the buckle 6 is clamped and fixed with the side wall of the base 422.

[0054] Specifically, when the buckle 6 is clamped and fixed with the side wall of the base 422, the buckle 6 and the side wall of the base 422 may be damaged due to stress concentration. After the through slot 7 is arranged on the inner side of the buckle 6, the side wall of the base 422 will deform when it is stressed, which facilitates the clamping and fixing between the buckle 6 and the side wall of the base 422. During installation, the buckle 6 can be smoothly clamped into the side wall of the base 422 by slightly pressing the surrounding plate 4214, which reduces the installation difficulty and improves the assembly efficiency.

[0055] As a preferred example of the present application, the base 422, the heating seat 410, the fixing frame 421 and the bracket 3 are fixed by bolt connection.

[0056] Specifically, the bolt connection operation is relatively simple, and the installation and disassembly can be completed using common tools. In the washing machine production process, workers can quickly assemble and produce. In the later maintenance and repair, the relevant parts can be easily disassembled, thereby facilitating the inspection, repair or replacement of parts of the heating assembly 4 and reducing maintenance costs.

[0057] As a preferred example of the present application, the upper end of the bracket 3 is provided with a fixing portion 31, and the bolt is installed in the fixing portion 31 after passing through the base 422, the heating seat 410, the fixing frame 421 and the bracket 3 in sequence.

[0058] Specifically, the bolt is installed in the fixing portion 31, which provides a stable force point for the bolt, so that the connection between the base 422, the heating seat 410, the fixing frame 421 and the bracket 3 is more firm. When the washing machine is running and vibrating, the bolt can be effectively prevented from loosening, the stability of the heating assembly 4 is ensured, and the influence of part shaking on the normal use of the washing machine is avoided.

[0059] As a preferred example of the present application, one side of the bracket 3 is provided with a baffle, which facilitates the positioning and installation of the protection frame 42 when the protection frame 42 is installed.

[0060] As a preferred example of the present application, a rib plate is arranged between the bracket 3 and the outer cylinder 2 to enhance the connection strength between the bracket 3 and the outer cylinder 2.

[0061] The washing machine further comprises a driving motor, a transmission assembly, a control panel, a cover plate and the like, and the specific structure and assembly relationship thereof are prior art and will not be described here.

[0062] In summary, the washing machine has the following advantages: 1) The bracket 3 is arranged at the lower part of the outer cylinder 2, and the heater 41 is fixed by cooperation of the bracket 3 and the protection frame 42. The overall volume of the heating assembly 4 is small, the occupied space of the outer cylinder 2 is reduced, the miniaturization design of the washing machine is facilitated, the indoor space occupation is reduced, the transportation and storage costs are reduced, and the applicability of the product in a limited space is improved; 2) The bracket 3 is arranged near the edge of the outer cylinder 2, the space around the outer cylinder 2 is reasonably utilized, the structure layout inside the washing machine is more compact, and the miniaturization design of the washing machine is facilitated.

[0063] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application should be subject to the scope defined by the claims.
