[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0028] Below, refer to the attached Figures 1 to 5 Describe the drum assembly and washing machine according to the embodiments of the present utility model.
[0029] As Figures 1 to 5 shown, the drum assembly according to the embodiment of the present utility model includes: an inner cylinder (not shown), an outer cylinder 1, a heater 2, and an electrolysis module 3. The inner cylinder is disposed inside the outer cylinder 1. The inner side of the outer cylinder 1 has an outer cylinder wall 14. A counterbore 12 is provided at the bottom of the outer cylinder wall 14. The heater 2 is disposed between the outer cylinder 1 and the inner cylinder and is arranged adjacent to the bottom of the outer cylinder wall 14. At least part of the electrolysis module 3 is installed in the counterbore 12.
[0030] For the drum assembly according to the embodiment of the present utility model, since at least part of the electrolysis module 3 is installed in the counterbore 12, the electrolysis module 3 can be hidden, and the normal electrolysis work of the electrolysis module 3 will not be affected. When the heater 2 dries out, since the electrolysis module 3 is hidden in the counterbore 12, the electrolysis module 3 can be protected, so as to reduce the problem of damage to the electrolysis module 3 caused by the dry burning of the heater 2, which is beneficial to extending the service life of the electrolysis module 3.
[0031] It can be understood that in the embodiment of the present utility model, the outer cylinder wall encloses a water storage cavity 11, the counterbore 12 communicates with the water storage cavity 11, and the heater 2 is disposed below the inner cylinder and is arranged adjacent to the bottom of the water storage cavity 11.
[0032] In related art, due to the limited installation space for the electrolysis module and heater, the electrolysis module is usually close to the heater or directly integrated into the heater. When there is less water in the cylinder, the heating tube will dry out and affect the service life of the electrolysis module. In addition, the electrolysis module of related art is directly installed on the inner wall of the water storage chamber, that is, the electrolysis module protrudes from the inner wall of the outer cylinder. In the above solution, when the heater dry-burns, the electrolysis module is easily damaged due to its close distance to the heater. When the distance between the heater and the electrolysis module is increased, it will occupy more space in the outer cylinder, which is not convenient for the arrangement of other components.
[0033] The drum assembly of the embodiment of the present invention is provided with a countersunk hole 12 on the outer cylinder 1 and hides the electrolysis module 3 to avoid the problem of damage to the electrolysis module 3 caused by dry burning of the heater 2, and has a better use effect.
[0034] It should be noted that the electrolysis module 3 (i.e., the blue oxygen module) can generate a large number of hydroxyl radicals by electrolyzing water or air containing water. By utilizing the strong oxidizing property of hydroxyl radicals, it decomposes or inactivates hydrogen in bacteria, allergens, or odor molecules, thereby achieving the effect of sterilization and deodorization.
[0035] Alternatively, as Figure 2 and Figure 3 As shown, the top of the electrolysis module 3 is no higher than the upper end of the countersunk hole 12. It is understandable that the upper end of the electrolysis module 3 is completely sunk into the countersunk hole 12, thereby further reducing the distance between the electrolysis module 3 and the heater 2, thereby protecting the electrolysis module 3 and reducing the problem of damage to the electrolysis module 3 caused by dry burning of the heater 2, which is conducive to extending the service life of the electrolysis module 3.
[0036] In one example, the distance between the top end of the electrolysis module 3 and the upper end of the countersunk hole 12 is H, where 0 ≤ H ≤ 20 mm. It is understood that the distance H between the upper end of the electrolysis module 3 and the upper end of the countersunk hole 12 is between 0 and 20 mm. For example, H can be 0, 5 mm, 10 mm, 15 mm, or 20 mm.
[0037] The inventors of the present application have found through experimental research that when H is set between 0-20 mm, it can not only prevent the problem of dry burning of the heater 2 causing damage to the electrolysis module 3, but also make the height size of the roller assembly smaller, thereby improving the structural compactness of the roller assembly and facilitating the arrangement of components on the outside of the outer cylinder 1.
[0038] Alternatively, as Figure 2As shown, the heater 2 penetrates axially into the water storage cavity 11 of the outer cylinder 11 along the outer cylinder 1, and the heater 2 is disposed directly above the counterbore 12. It can be understood that the heater 2 penetrates into the water storage cavity 11 from the rear wall surface of the outer cylinder 1, and the heater 2 is disposed directly above the electrolysis module 3. By arranging the heater 2 directly above the counterbore 12 in the drum assembly of the embodiment of the present invention, compared with the scheme in which the heater 2 and the electrolysis module 3 are arranged at intervals along the circumferential direction of the outer cylinder 1, the arrangement of the heater 2 and the electrolysis module 3 can be made more compact, and the electrolysis module 3 will not be affected.
[0039] As Figure 2 shown, since the heater 2 is disposed directly above the electrolysis module 3, and both the heater 2 and the electrolysis module 3 are installed at the bottom of the water storage cavity 11, the bottom space of the water storage cavity 11 can be fully utilized, and the water near the electrolysis module 3 is heated by the heater 2, which can improve the electrolysis efficiency of the electrolysis module 3.
[0040] For example, the heater 2 is a heating pipe, and the heating pipe extends axially along the outer cylinder 1 and is arranged in a meandering manner.
[0041] As Figure 1 and Figure 2 shown, the outer cylinder wall 14 encloses a main chamber 111 and a drainage groove 112. In other words, the water storage cavity 11 of the outer cylinder 1 includes the main chamber 111 and the drainage groove 112. The drainage groove 112 is disposed below the main chamber 111 and is recessed downward. The distance between the bottom surface of the drainage groove 112 and the axis of the outer cylinder 1 is greater than the distance between the inner wall surface of the main chamber 111 and the axis of the outer cylinder 1. It can be understood that the inner wall surface of the main chamber 111 is an arc surface, the drainage groove 112 is recessed downward, and the drainage groove 112 is farther from the axis of the outer cylinder 1 than the inner wall surface of the main chamber 111. The main chamber 111 is used to install an inner cylinder (not shown), and the inner cylinder can rotate within the outer cylinder 1. The drainage groove 112 is recessed downward to define an installation space with the inner cylinder.
[0042] As Figure 2 and Figure 3 shown, the heater 2 is installed in the drainage groove 112, and the counterbore 12 is opened on the bottom surface of the drainage groove 112. Therefore, the residual water in the outer cylinder 1 will gather in the drainage groove 112 to reduce the probability of the heater 2 running dry. And since the counterbore 12 is opened on the bottom surface of the drainage groove 112, the electrolysis module 3 can electrolyze the residual water in the outer cylinder 1, and the water in the drainage groove 112 will also flow into the counterbore 12 to further improve the electrolysis effect and electrolysis efficiency of the electrolysis module 3.
[0043] For example, the bottom surface of the drainage groove 112 is a plane, and a drainage channel communicating with the outside is provided on the bottom surface of the drainage groove 112 to drain all the water in the drainage groove 112.
[0044] Optionally, asFigures 3 to 5 As shown in the figure, the electrolysis module 3 includes an electrolysis body 31 and a housing 32. The electrolysis body 31 is installed inside the housing 32 and extends into the counterbore 12, and the housing 32 is installed at the lower port of the counterbore 12. Since the housing 32 is installed at the lower port of the counterbore 12, the distance between the heater 2 and the housing 32 can be increased, thus avoiding the problem that the heater 2 dries out and damages the housing 32.
[0045] As Figure 3 shown in the figure, the lower port of the counterbore 12 has a downwardly extending annular flange 13, and the upper end face of the housing 32 is provided with an annular mating groove 321. The annular flange 13 is inserted into the mating groove 321. It can be understood that the annular flange 13 is arranged circumferentially around the lower edge of the counterbore 12, the annular flange 13 extends vertically downward, and extends into the mating groove 321. The insertion fit between the annular flange 13 and the mating groove 321, on the one hand, can facilitate the installation and positioning of the electrolysis module 3, and on the other hand, can reduce the probability of water leakage caused by the poor sealing between the lower port of the existing counterbore 12 and the housing 32.
[0046] Specifically, as Figures 3 to 4 shown in the figure, the electrolysis module 3 further includes a sealing ring 33. The sealing ring 33 is arranged in the mating groove 321 and elastically abuts against the annular flange 13. For example, the sealing ring 33 can be an elastic rubber ring. By arranging the sealing ring 33 between the annular flange 13 and the mating groove 321 in the drum assembly of the embodiment of the present utility model, the sealing and waterproof effect between the counterbore 12 and the housing 32 can be further improved.
[0047] In one example, as Figures 4 to 5 shown in the figure, the electrolysis module 3 further includes a threaded member (not shown). The housing 32 has an ear seat 322, and the threaded member passes through the ear seat 322 and the outer cylinder 1 in the direction from bottom to top, thereby facilitating the installation and disassembly of the electrolysis module 3. For example, there are multiple ear seats 322, the multiple ear seats 322 are arranged at intervals along the circumference of the housing 32, there are multiple threaded members, and the multiple threaded members are connected to the multiple ear seats 322 in one-to-one correspondence.
[0048] Optionally, as Figure 3 and Figure 5 shown in the figure, the electrolysis body 31 includes an electrolysis plate 311 and a circuit board 312. The electrolysis plate 311 is electrically connected to the circuit board 312. The electrolysis plate 311 is installed on the upper side of the housing 32 and is located in the counterbore 12. Since the electrolysis plate 311 is installed in the counterbore 12, the water in the drainage groove 112 and the counterbore 12 can be electrolyzed by the electrolysis plate 311.
[0049] The circuit board 312 is installed on the lower side of the housing 32 and is located outside the counterbore 12. Since the circuit board 312 is installed on the lower side of the housing 32, the circuit board 312 is arranged away from the heater 2. On the one hand, the temperature in the area of the circuit board 312 can be reduced when the heater 2 is working. On the other hand, the probability of the circuit board 312 coming into contact with water can be reduced, improving the reliability of the electrolysis module 3 during operation.
[0050] It should be noted that the electrolysis plate 311 includes a cathode plate and an anode plate. An electrolysis area is defined between the cathode plate and the anode plate to electrolyze water or air containing water, thereby generating a large amount of hydroxyl radicals to achieve the effects of sterilization and odor removal.
[0051] Optionally, as Figure 3 and Figure 4 shown, the electrolysis module 3 further includes a protective cover 34 and a connector (not shown). The protective cover 34 is disposed in the counterbore 12 and is installed at the upper end of the electrolysis plate 311. A plurality of water-permeable holes are provided at the upper end of the protective cover 34. The protective cover 34 can protect the electrolysis plate 311 to extend the service life of the electrolysis module 3. The connector is installed on the lower side of the circuit board 312 and is used to install control and connection lines to control the opening and closing of the electrolysis module 3.
[0052] For example, the upper end surface of the protective cover 34 can be flush with the upper port of the counterbore 12 to improve the integrity of the outer cylinder 1.
[0053] Another embodiment of the washing machine of the present utility model includes the drum assembly of the embodiment of the present utility model. The drum assembly further includes an inner drum, and the inner drum is rotatably installed inside the outer cylinder 1. In the example of the present application, the washing machine is a drum washing machine.
[0054] In the washing machine of the embodiment of the present utility model, since at least part of the electrolysis module 3 is installed in the counterbore 12, the electrolysis module 3 can be hidden. And since the counterbore 12 communicates with the water storage chamber 11, it will not affect the normal electrolysis operation of the electrolysis module 3. When the heater 2 undergoes dry burning, since the electrolysis module 3 is hidden in the counterbore 12, the electrolysis module 3 can be protected to reduce the problem of damage to the electrolysis module 3 caused by the dry burning of the heater 2, which is beneficial to extending the service life of the electrolysis module 3.
