Description

Technical Field

[0001] The present invention relates to the field of laundry equipment, and in particular to a washing machine with a variable-stroke waterway and line-carrying mechanism. Background Art

[0002] Due to the structural characteristics of drawer-type washing machines, the associated water and wiring systems in the drawer are dynamic. This requirement, compared to conventional washing machines, requires ensuring that the piping, including water inlet and outlet, and sealing requirements, are met for proper operation during the user's drawer movement—that is, when the drawer is opened and closed. Drawer-type washing machines have limited available space, with the space being even narrower in the direction of movement relative to the vertical direction. This makes implementing dynamic water and wiring systems for drawer-type washing machines extremely challenging.

[0034] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0035] like Figure 1 、 2 As shown in Figure 3, the mechanism for carrying a waterway and circuit with a variable stroke includes: a variable stroke mechanism, which is connected between the drawer-type washing machine 6 and the washing machine frame 1. When the drawer-type washing machine 6 is pulled out, the variable stroke mechanism unfolds in a direction forming an angle with the pulling direction; when the drawer-type washing machine 6 is returned to the washing machine frame 1, the variable stroke mechanism folds between the rear part of the drawer-type washing machine 6 and the washing machine frame 1. Specifically, one end of the variable stroke mechanism can be connected to the beam at the corner of the washing machine frame 1, and the other end can be connected to the side of the rear part of the drawer-type washing machine 6. The waterway and / or circuit of the washing machine are carried on the variable stroke mechanism. When the drawer-type washing machine 6 moves in the pulling direction, the variable stroke mechanism drives the waterway and / or circuit to change its stroke to adapt to the stroke of the drawer-type washing machine 6. The variable stroke mechanism includes a bending link mechanism, one end of which is rotatably connected to the drawer-type washing machine 6 via a first rotating mechanism 4. In this embodiment, the first rotating mechanism 4 is vertically arranged and rotatably connected to a fixed base 3, which is connected to the drawer-type washing machine 6. The first rotating mechanism 4 can rotate perpendicular to the direction of withdrawal. The other end of the bending link mechanism is rotatably connected to the washing machine frame 1 via a second rotating mechanism 5. The second rotating mechanism 5 is vertically arranged and rotatably connected to the fixed base 3, which is connected to the washing machine frame 1. Using two fixed bases 3 can make the structure more stable and the withdrawal and withdrawal smoother. The bending link mechanism includes multiple connecting rods 14, which are rotatably connected end to end by a connecting member. In this embodiment, the connecting member is a pin 2. Two adjacent connecting rods 14 can rotate about the pin 2, thereby allowing the bending link mechanism to bend in accordance with the movement of the drawer-type washing machine 6.

[0036] It should be noted that in this embodiment, the bending link mechanism includes three links 14, but the number of links 14 is not limited to this. During implementation, those skilled in the art may determine the number of links 14 based on actual needs. By using a variable-stroke mechanism to support the circuit and waterway, the waterway and circuit move along with the drawer washing machine, thereby ensuring that the drainage method is not restricted, and both upper and lower drainage can be used.

[0037] Furthermore, if Figure 4 As shown, one side of the connecting rod 14 is provided with a water pipe slot for securing the waterway, and the other side is provided with a wiring trough for securing the circuit. The water pipe slot is arranged along the length of the connecting rod 14, and the waterway is clamped in the water pipe slot. The waterway uses a flexible water pipe that can bend along with the bending connecting rod mechanism. The wiring trough is arranged along the length of the connecting rod 14 and is divided into a strong current wiring trough and a weak current wiring trough. The strong current wiring trough and the weak current wiring trough can be arranged in parallel. Separating the strong current and weak current wiring troughs complies with electrical safety standards. By providing the water pipe slot and wiring trough on both sides of the connecting rod 14, the waterway and the electrical circuit can be separated, improving safety.

[0038] In some preferred embodiments, Figure 5 and 6 As shown, the bending link mechanism also includes: a limiting mechanism, which includes: a groove 13 arranged at one end of the link 14, and a protrusion 12 arranged at one end of the adjacent link 14, the protrusion 12 is located in the corresponding groove 13, and the protrusion 12 cooperates with the groove 13 to limit the maximum rotation angle of the link 14.

[0039] Because the connecting rods 14 are connected by a revolute joint, the revolute joint motion between the connecting rods 14 is uncertain during the drawer washing machine's extension and extension process, which can cause the variable-stroke waterway and circuit structure to fail, and there is a risk of pipe breakage and wear. By providing a limiter mechanism, the spatial position of the connecting rods 14 can be completely restricted. The limiter structure has a range of motion of 0°-58°, and the entire bending connecting rod structure can be limited to a range of motion of 115°-173°, preventing pipe breakage and wear.

[0040] In some preferred embodiments, Figure 7 and 8 As shown, the variable stroke mechanism also includes: a water pipe anti-freezing and cracking mechanism 9, which includes a shell with a water flow chamber 15 formed inside, and the shell has a water inlet and a water outlet connected to the water flow chamber 15, and the water inlet and the water outlet are respectively connected to the water channel, and a plurality of air chambers 16 are arranged at intervals above the water flow chamber 15, and each air chamber 16 is connected to the water flow chamber 15 through an air chamber port 17.

[0041] In order to reduce the wear of the pipeline, a pipeline connection mechanism, such as a reducer 7, is added between the bending connecting rod mechanism. However, due to the connection mechanism, water is easily stored in the pipeline, and in winter or in colder areas in the north, it may freeze and crack. Therefore, the provision of a water pipe anti-freeze cracking mechanism 9 can solve this problem well. Since a plurality of air chambers 16 are provided above the water passage chamber 15, when water enters the water passage chamber 15 through the water inlet, the liquid level will not be higher than the position of the air chamber port 17, that is, the water will never fill the structural chamber, ensuring that the water freezes and compresses the gas in the air chamber 16 to prevent the water channel from freezing and cracking. Furthermore, in order to reduce production costs and facilitate installation, the water pipe anti-freeze cracking mechanism 9 can be integrated on the connecting rod 14.

[0042] In some preferred embodiments, Figure 9 As shown, the variable stroke mechanism also includes a telescopic mechanism, which is connected to the bellows 8 of the waterway and can be extended and retracted along with the bellows 8. The telescopic mechanism includes an outer sleeve 10 and an inner sleeve 11. One end of the outer sleeve 10 is connected to the first rotating mechanism 4, one end of the inner sleeve 11 is sleeved within the outer sleeve 10, and the other end of the inner sleeve 11 is connected to the second rotating mechanism 5 via screws. The bellows 8 is arranged inside the inner sleeve 11 along the axis of the inner sleeve 11, and the two ends of the bellows 8 are respectively connected to the waterway. When the drawer-type washing machine 6 moves in the pulling direction, the bellows 8 can be extended and retracted, and the inner sleeve 11 can be extended and retracted along the axial direction of the outer sleeve 10, thereby changing the length of the telescopic mechanism to match the stroke of the drawer-type washing machine 6.

[0043] In some preferred embodiments, Figure 10 As shown, the telescopic mechanism includes a telescopic cage, and a bellows 8 is arranged in the telescopic cage along the axis of the telescopic cage. Since the working principle of the telescopic cage is the same as that of the telescopic mechanism, it will not be described in detail here.

[0044] In some preferred embodiments, a line protection chain can be used instead of the bending link mechanism, which can also carry and protect waterways and lines.

[0045] Correspondingly, the present invention further provides a washing machine, which includes a washing machine main body and a supporting mechanism. The supporting mechanism is the supporting mechanism with a variable stroke water channel and a line as described in the above embodiment.
