Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following reference Figure 1-3The present invention describes an automatic dispensing device 100 according to an embodiment of the present invention. The automatic dispensing device 100 includes an automatic dispensing body 10 and a connecting wire 20. The automatic dispensing device 100 is detachably installed inside a washing machine and dispenses detergent into the washing machine.

[0027] In other words, the automatic dispensing device 100 is independent of the washing machine (not shown in the figure). When purchasing the machine, the user can choose whether or not to configure the automatic dispensing device 100 as needed. Furthermore, during use, the user can remove the automatic dispensing device 100 from the washing machine for cleaning, repair, or replacement. If the user did not purchase the automatic dispensing device 100, they can also configure it as needed to add the automatic dispensing function, thus satisfying the user's need for flexibility in using the washing machine.

[0028] Specifically, the automatic dispensing unit 10 has an inlet end and an outlet end. The inlet end is connected to the water inlet pipe of the washing machine, and the outlet end is connected to the water inlet of the washing machine tub. One end of the connecting wire 20 is connected to the automatic dispensing unit 10, and when the automatic dispensing device 100 is installed inside the washing machine, the other end of the connecting wire 20 is connected to the washing machine controller. The washing machine controller has an automatic dispensing function button, which the user can press to activate the automatic dispensing device 100, thereby automatically dispensing detergent into the washing machine.

[0029] In other words, the automatic dispensing device 100 does not require a separate controller; instead, it is controlled by the washing machine's controller. Specifically, when the washing machine is operating, the automatic dispensing function is activated on the washing machine controller. Water pre-enters the automatic dispensing unit 10, mixes with the detergent, and then enters the washing machine drum to wash the clothes.

[0030] Therefore, the automatic dispensing device 100 for washing machines according to the present invention has a simple structure and low manufacturing cost.

[0031] It should be noted that the automatic dispensing device 100 of this utility model is set independently of the washing machine. The automatic dispensing device 100 can be used with different types and models of washing machines, which increases the applicability of the automatic dispensing device 100. The automatic dispensing device 100 can be used to dispense detergent into different types of washing machines. In particular, the automatic dispensing device 100 can also be installed in washing machines that do not have an automatic dispensing function to meet the needs of the automatic dispensing function.

[0032] Therefore, the automatic dispensing device 100 for washing machines according to the present utility model embodiment can be detachably installed inside the washing machine according to the user's needs, and its operation is controlled by the controller of the washing machine. The automatic dispensing device 100 has a simple structure, low production cost, and good compatibility.

[0033] In some embodiments of this utility model, such as Figure 1 As shown, the automatic dispensing device 100 may further include a water inlet pipe 30. The water inlet pipe 30 is located between the inlet end of the automatic dispensing body 10 and the outlet of the water inlet pipe. This facilitates the installation of the automatic dispensing device 100 with the washing machine and improves the ease of installation of the automatic dispensing device 100.

[0034] Optionally, the automatic dispensing device 100 may further include an inlet valve 40. The inlet valve 40 is connected to the inlet pipe 30 and may be a one-way valve. Thus, the inlet valve 40 can control the connection between the inlet pipe and the automatic dispensing device 100, and the one-way valve can prevent liquid containing detergent from the automatic dispensing device 100 from flowing back into the inlet pipe, thereby preventing contamination of the household tap water pipe.

[0035] Optionally, the automatic dispensing device 100 may further include a corrugated pipe 50. The corrugated pipe 50 is disposed between the outlet end of the automatic dispensing body 10 and the water inlet of the washing machine tub. The corrugated pipe 50 has elastic expansion and contraction capabilities. Thus, by adjusting the length of the corrugated pipe 50, the automatic dispensing device 100 can be adapted to different models of washing machines, improving the compatibility of the automatic dispensing device 100.

[0036] In one specific embodiment of this utility model, such as Figure 1 As shown, the automatic dispensing device 100 is installed on the top of the washing machine and located at the rear of the washing machine. The water inlet pipe 30 is located on the left rear side of the automatic dispensing body 10, the connecting wire 20 is located on the right rear side of the automatic dispensing body 10, and the corrugated pipe 50 is located on the left front side of the automatic dispensing body 10. This facilitates the installation of the automatic dispensing device 100 and makes its structural layout more rational.

[0037] In another specific embodiment of this utility model, the automatic dispensing body 10 may include: a water pipe channel, a storage box, and a pump body. The water pipe channel is used to connect the inlet end and the outlet end. The inlet of the pump body is connected to the storage box, and the outlet of the pump body is connected to the water pipe channel. The pump body is used to pump washing material into the water pipe channel. The washing material is mixed with the water in the water pipe channel and then transported into the washing machine.

[0038] When the washing machine is working, the water inlet valve 40 is opened, and water enters the water pipe channel from the washing machine's water inlet pipe. The pump body pumps the detergent in the storage box into the water pipe channel, and the detergent mixes with the water in the water pipe channel before being transported into the washing machine.

[0039] The storage compartments can be multiple, each storing a different detergent. Each storage compartment can correspond to a single pump, or multiple storage compartments can share a single pump. The pump can be a piston pump.

[0040] Optionally, the automatic dispensing device 100 may further include a liquid level sensor (not shown), which is connected to the water pipe channel. The liquid level sensor detects whether there is liquid flow in the water pipe channel. When the liquid level sensor detects liquid flow in the water pipe channel, the washing machine controller can activate the pump to pump detergent into the water pipe channel. The detergent can be one or more of detergent, fabric softener, and fragrance.

[0041] The washing machine according to an embodiment of the present invention includes: a housing (not shown) and a control panel assembly. The housing has an installation space for mounting an automatic dispensing device 100. The control panel assembly is disposed on the housing and may include a controller. The controller has an automatic dispensing function, and when the automatic dispensing device 100 is installed inside the housing, the controller is connected to the automatic dispensing device 100.

[0042] In other words, the washing machine that matches the automatic dispensing device 100 of the above embodiment has an automatic dispensing function button on the controller, and a wire is led out from the controller. The connector can be fixed at the rear of the casing. When the automatic dispensing device 100 is installed in the casing, the connecting wire 20 of the automatic dispensing device 100 is connected to the wire of the controller, thereby realizing the automatic dispensing function of the washing machine. In this way, users can purchase it at any time, and after-sales on-site installation and disassembly repair are more convenient.

[0043] Users can choose whether to include the automatic detergent dispensing function when purchasing the machine. If the automatic detergent dispensing function is not selected, the purchase price will be reduced by the cost of the automatic detergent dispensing function, similar to the price of a regular washing machine. If users wish to add the automatic detergent dispensing function later, they can purchase the automatic detergent dispensing device 100 from the store at any time, and it will be installed by after-sales personnel. If the automatic detergent dispensing device 100 malfunctions, after-sales service can disassemble it separately and take it to a service center for repair, or replace it with a new automatic detergent dispensing device 100; this will not affect the user's use of the washing machine.

[0044] Users can easily select the automatic detergent dispensing function for their washing machines, reducing the hassle and cost of replacing the washing machine to enable the automatic detergent dispensing function. This also reduces the overall machine repair rate and repair costs, improves the cost-effectiveness and popularity of smart washing machines with automatic detergent dispensing function, and enhances the market competitiveness of smart washing machines.

[0045] Therefore, the washing machine according to this utility model embodiment can automatically select and equip itself with an automatic dispensing device 100 according to the user's needs, increasing the versatility of the washing machine's functions. Reference can be made to Chinese Patent 201621101521.7 regarding an automatic dispensing device for a washing machine.

[0046] However, the automatic dispensing device 100 is usually placed directly inside the washing machine. The inlet of the automatic dispensing device 100 is connected to the washing machine's water inlet pipe, and the outlet is connected to the washing machine's tub inlet. If it is not fixed, the connection is prone to loosening, displacement, or even detachment due to the vibration generated by the washing machine's operation. It may also cause bends in the connected pipe. Over time, if the shaking of the washing machine causes the connected pipe to bend back and forth, it may cause damage to the connected pipe, resulting in leakage and posing a safety hazard.

[0047] In summary, a connecting mechanism 60 is provided on the automatic dispensing body 10. The connecting mechanism 60 includes a rotation damper 601, a connecting block 602, a slot 603, and a locking block 604. One end of the rotation damper 601 is fixed to the connecting block 602, and the other end of the rotation damper 601 is fixed to the slot 603. The locking block 604 is fixedly connected to the automatic dispensing body 10, and the locking block 604 is slidably connected to the slot 603, with the locking block 604 and the slot 603 nested together.

[0048] When installing the automatic dispensing device 100, first install the rotation damper 601 inside the washing machine through the connecting block 602. The connecting block 602 has screw holes, and the connecting block 602 can be fixed inside the washing machine with screws. Then, the locking block 604 set on the automatic dispensing body 10 is aligned with the locking slot 603 and inserted. In order to prevent the locking block 604 from falling off, an anti-slip layer, such as a rubber layer, can be provided on the surface of the locking block 604, which can increase the friction between the locking block 604 and the locking slot 603 and prevent the automatic dispensing body 10 from falling off.

[0049] Then, by rotating the automatic dispensing body 10, the position of the automatic dispensing body 10 inside the washing machine can be adjusted, so that the water inlet pipe 30 and the corrugated pipe 50 are in a straight state and this state is fixed. Even if the washing machine vibrates during operation, the water inlet pipe 30 and the corrugated pipe 50 will not bend back and forth. This not only makes the whole thing more beautiful, but also reduces the problem of pipe bending and damage, and improves safety.

[0050] The rotational damper 601 has mature applications in existing technology. It is briefly introduced below, including: housing, rotating shaft, damping medium, blades or piston, sealing device and adjustment device.

[0051] Housing: Generally made of metal or high-strength plastic, used to protect the internal structure and provide an interface for mounting and fixing, allowing the damper to be connected to other components.

[0052] The pivot shaft is the core rotating component of the damper, usually made of metal, possessing high strength and wear resistance. It runs through the center of the damper, with both ends extending out of the outer casing, used to connect rotating components requiring damping, such as doors, windows, and robotic arms.

[0053] Damping medium: This is the key component for achieving the damping effect. Common damping media include silicone oil, air, and magnetohydrodynamics. Taking silicone oil as an example, it fills the cavity between the outer shell and the shaft. When the shaft rotates, the silicone oil generates viscous resistance, thereby playing a damping role.

[0054] Blades or pistons: Components that interact with the damping medium. In some designs, blades are mounted on a shaft, rotating within the damping medium and generating damping force through friction and compression with the medium. In air dampers, a piston structure may be used, where the damping effect is achieved through the movement of the piston within an air chamber.

[0055] Sealing devices: These prevent leakage of the damping medium and ensure the stable performance of the damper. Common sealing methods include rubber seals and oil seals, which are installed at the connection between the shaft and the housing, as well as at various joints of the housing.

[0056] Adjustment device: Some bidirectional rotary dampers 601 are equipped with an adjustment device for adjusting the magnitude of the damping force. For example, by rotating the adjustment knob, the flow cross section or degree of compression of the damping medium can be changed, thereby achieving precise control of the damping force to adapt to different application scenarios and needs.
