Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a drying and sealing structure for a drum washing machine. Background Technology

[0002] Front-loading washing machines have been developed for many years. Because they protect clothes well, front-loading washing machines generally have an outer shell and an inner drum to hold the washing water. Inside the outer drum is a drum to hold the laundry. On the back of the outer drum is a motor and shaft to rotate the drum. Some existing front-loading washing machines can also perform a drying function. The principle is to generate hot air through a drying device and blow the hot air into the drum, so that the damp clothes inside the drum are dried, thus greatly improving the convenience of washing clothes.

[0003] Since the drying unit needs to be installed on the outer drum of the drum washing machine, and the drying unit is usually connected to the outer drum by screws, as the drum washing machine is used, the mounting screws used to fix the drying unit will gradually loosen, making it impossible to lock the position of the drying unit, further reducing the sealing effect between the drying unit and the outer drum, thereby affecting the drying effect of the washing machine and increasing the drying time and energy consumption.

[0004] Therefore, it is of great importance to design a drying and sealing structure for drum washing machines to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a drying and sealing structure for drum washing machines. This structure aims to solve the technical problem that existing drum washing machine drying and sealing structures gradually loosen with the use of the drum washing machine, leading to the inability to lock the position of the drying device, reducing the sealing effect, affecting the drying effect of the washing machine, and increasing the drying time and energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drying and sealing structure for a drum washing machine includes a washing machine shell, an outer drum fixedly installed inside the washing machine shell, an inner drum rotatably connected inside the outer drum, a mating sleeve fixedly connected to the outer side of the outer drum, a heating box fixedly installed on the outer side of the mating sleeve, a fan fixedly installed on the outer side of the heating box, and sealing mechanisms installed between both ends of the heating box and the mating sleeve.

[0008] The sealing mechanism includes a positioning edge fixedly connected to the bottom of the heating box. The inside of the docking sleeve is provided with a positioning groove that is adapted to the positioning edge. A first sealing ring is sleeved on the inner side of the positioning groove. Locking boxes are fixedly installed on the outer side of the docking sleeve at both ends of the positioning edge.

[0009] As a preferred embodiment of this utility model, a locking block is slidably connected inside the locking box, and one end of the locking block located outside the locking box abuts against the positioning edge. A spring is fixedly connected to one end of the locking block located inside the locking box, and an operating handle is fixedly connected to the top of the locking block.

[0010] As a preferred embodiment of this utility model, the operating handle is slidably connected to the locking box via a sliding groove, and multiple sets of anti-slip textures are provided on the outer side of the operating handle.

[0011] As a preferred embodiment of this utility model, a fixing pin is inserted into the inside of the operating handle, and a fixing hole is provided at the end of the sliding groove away from the fixing pin, and the fixing pin is threadedly connected to the fixing hole.

[0012] As a preferred embodiment of this utility model, the front of the washing machine casing is hinged to a cover, and a mating ring is fixedly connected to the inner side of the cover and the inner side of the front end of the inner drum. The inner drum is rotatably connected to the mating ring, and a second sealing ring is sleeved on the outer side of the mating ring.

[0013] As a preferred embodiment of this utility model, a drying air duct is formed between the outer cylinder and the inner cylinder, and multiple sets of guide fan blades are rotatably connected inside the drying air duct.

[0014] As a preferred embodiment of this utility model, a heating tube is fixedly installed inside the heating box, and an air guide is provided inside the docking sleeve between the heating box and the outer cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, through the coordinated design of the heating box, the docking sleeve, and the sealing mechanism, when installing the heating box, its outer positioning edge is aligned with the positioning groove on the outer side of the docking sleeve and inserted. The outer side of the positioning edge is fixed by the locking box.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A drying and sealing structure for a drum washing machine includes a washing machine outer shell 1, an outer drum 2 fixedly installed inside the washing machine outer shell 1, an inner drum 3 rotatably connected inside the outer drum 2, a docking sleeve 4 fixedly connected to the outer side of the outer drum 2, a heating box 5 fixedly installed on the outer side of the docking sleeve 4, a fan 6 fixedly installed on the outer side of the heating box 5, and a sealing mechanism 7 installed between both ends of the heating box 5 and the docking sleeve 4.

[0028] First, in this embodiment, the specific structure of the sealing mechanism 7 is as follows:

[0029] The sealing mechanism 7 includes a positioning edge 701 fixedly connected to the bottom of the heating box 5. The inside of the docking sleeve 4 is provided with a positioning groove 702 adapted to the positioning edge 701. A first sealing ring 703 is sleeved on the inner side of the positioning groove 702. Locking boxes 704 are fixedly installed on the outer side of the docking sleeve 4 at both ends of the positioning edge 701. When installing the heating box 5, the outer positioning edge 701 is aligned with the positioning groove 702 on the outer side of the docking sleeve 4 and inserted. The outer side of the positioning edge 701 is fixed by the locking box 704. Thus, when the heating box 5 is working, the outer side of the positioning edge 701 is restricted by the positioning groove 702. The double fixation by the locking box 704 prevents the heating box 5 from becoming loose. At the same time, the first sealing ring 703 on the inner side of the positioning groove 702 can ensure the sealing of the heating box 5 after installation, thereby ensuring the sealing between the heating box 5 and the outer cylinder 2, reducing the drying time and energy consumption.

[0030] Furthermore, a locking block 705 is slidably connected inside the locking box 704, and one end of the locking block 705 located on the outside of the locking box 704 abuts against the positioning edge 701. A spring 706 is fixedly connected to one end of the locking block 705 located inside the locking box 704, and an operating handle 707 is fixedly connected to the top of the locking block 705. Before the positioning edge 701 is inserted into the inner side of the docking sleeve 4, the locking block 705 is slid in through the operating handle 707 to retract the locking block 705 into the interior of the locking box 704, thereby freeing up the installation position of the positioning edge 701. After the positioning edge 701 is fully inserted into the interior of the positioning groove 702, the operating handle 707 is released. Under the action of the spring 706, the locking block 705 pops out from the interior of the locking box 704, so that the locking block 705 abuts against the outside of the positioning edge 701 and presses down to fix the positioning edge 701, thereby improving the ease of installation of the heating box 5 while ensuring the fixing effect of the positioning edge 701.

[0031] Then, the operating handle 707 is slidably connected to the locking box 704 through the slide groove 708. Multiple anti-slip textures are provided on the outer side of the operating handle 707. When the operating handle 707 slides the locking block 705, the operating handle 707 slides inside the slide groove 708 and avoids slippage through the anti-slip textures, making operation convenient.

[0032] Furthermore, a fixing pin 709 is inserted into the inside of the operating handle 707, and a fixing hole 710 is provided at the end of the slide groove 708 away from the fixing pin 709. The fixing pin 709 is threadedly connected to the fixing hole 710. After the operating handle 707 is slid to the position of the fixing hole 710, the fixing pin 709 is screwed into the fixing hole 710, thereby fixing the operating handle 707 to prevent the locking block 705 from popping out, and thus facilitating the positioning edge 701 to be snapped into the inside of the positioning groove 702.

[0033] The washing machine casing 1 has a cover 101 hinged to the front. A mating ring 102 is fixedly connected to the inner side of the cover 101 and the inner side of the front end of the inner drum 3. The inner drum 3 is rotatably connected to the mating ring 102. A second sealing ring 103 is sleeved on the outer side of the mating ring 102. When the cover 101 is closed, the mating ring 102 is inserted into the inner side of the front end of the inner drum 3. The second sealing ring 103 can ensure the sealing of the front end of the inner drum 3, thereby preventing hot air from leaking out during drying and avoiding affecting the drying effect.

[0034] Secondly, a drying air duct 201 is formed between the outer cylinder 2 and the inner cylinder 3. Multiple sets of guide fan blades 202 are rotatably connected inside the drying air duct 201. During the drying operation, the airflow heated by the heating box 5 is introduced into the interior of the drying air duct 201 by the fan 6. After the airflow enters the interior of the drying air duct 201, it will be driven to rotate by the guide fan blades 202. The guide fan blades 202 guide the airflow to circulate between the outer cylinder 2 and the inner cylinder 3, thereby improving the drying efficiency.

[0035] Finally, a heating tube 501 is fixedly installed inside the heating box 5. An air guide 502 is opened inside the connecting sleeve 4 and between the heating box 5 and the outer cylinder 2. The airflow is introduced into the heating box 5 by the fan 6 and heated by the heating tube 501. Then, it is introduced into the drying air duct 201 through the air guide 502 for drying.

[0036] In this embodiment, the specific implementation scenario is as follows: When installing the heating box 5, its outer positioning edge 701 is aligned with the positioning groove 702 on the outer side of the docking sleeve 4 and inserted. Before inserting the positioning edge 701 into the inner side of the docking sleeve 4, the locking block 705 is slid into the locking box 704 by operating the handle 707, thereby freeing up the installation position of the positioning edge 701. Then, the positioning edge 701 is aligned with the positioning groove 702 and inserted. After the positioning edge 701 is fully inserted into the positioning groove 702, the operating handle 707 is released. Under the action of the spring 706, the locking block 705 springs out from the inside of the locking box 704. The locking block 705 abuts against the outer side of the positioning edge 701 and presses down to fix the positioning edge 701. When the heating box 5 is working, the positioning groove 702 restricts the outer side of the positioning edge 701, and the locking block 705 double fixes the heating box 5 to prevent it from loosening. At the same time, the first sealing ring 703 on the inner side of the positioning groove 702 can ensure the sealing of the heating box 5 after installation. The whole operation process is simple and convenient. Compared with the existing drum washing machine drying sealing structure, this utility model not only facilitates installation, but also ensures the sealing between the heating box 5 and the outer drum 2, reducing the drying time and energy consumption.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
