[0002] With the increasing demand for washing equipment in modern families, devices such as dish washing machines have gradually become popular. In these devices, the feeding mode of washing agent directly affects the washing effect and the use efficiency of the device. The traditional washing agent feeding device usually adopts a fixed chamber or a manual feeding mode, which has problems such as uneven feeding, difficulty in controlling the feeding amount, and the like, resulting in poor washing effect or waste of washing agent.

[0003] In order to overcome these problems, some automatic feeding devices are introduced in the prior art, but there are still deficiencies such as complex structure, high manufacturing cost, and inconvenient operation. In addition, in the design of multiple chambers, it is a technical difficulty to realize the synchronous opening and closing of multiple chambers, especially in occasions where different types of washing agent need to be accurately controlled.

Although the feeding device can feed multiple types of washing agent, it cannot realize the simultaneous opening of multiple feeding chambers.

[0005] Therefore, there is an urgent need for a washing agent feeding device with simple design, compact structure, and convenient operation, which can simultaneously open the openings of multiple chambers, so as to realize accurate feeding of washing agent, improve the washing effect, and adapt to different types of washing equipment such as dish washing machines.

[0043] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Those skilled in the art will understand that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] In the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] like Figs. 1 to 3As shown, the present invention provides a detergent dispensing device that enables precise dispensing of detergent in a washing machine. The device includes a dispensing chamber containing a first dispensing chamber 2 and a second dispensing chamber 3 that are not interconnected. A movable component 1 is designed to move relative to the first and second dispensing chambers 2 and 3, and upon reaching a target position, simultaneously opens the openings of both chambers, thereby releasing the detergent into the washing machine.

[0046] The movable component 1 can slide along a preset trajectory within the dispensing chamber until it reaches the target position. When the movable component 1 is in its initial position, the openings of both dispensing chambers are closed to prevent premature detergent leakage. As the movable component 1 moves, it gradually contacts and opens the openings of the first dispensing chamber 2 and the second dispensing chamber 3. In this way, the detergent can be released as needed, ensuring accurate dispensing.

[0047] The design of this device makes it suitable for various types of detergents and washing equipment, especially for applications such as dishwashers where precise control of multiple detergent dispensing methods is required. Through its rational structural design, the detergent dispensing device of this invention can effectively improve washing efficiency, reduce detergent waste, and simplify the operation of the equipment.

[0048] In this invention, the movable part 1 in the detergent dispensing device is a deformable guide rod. The guide rod can be deformed in various ways and moved to the target position, thereby opening the openings of the first dispensing chamber 2 and the second dispensing chamber 3.

[0049] The guide rod moves by deforming under stress. Specifically, the guide rod can be made of an elastic material that deforms when an external force (such as mechanical, hydraulic, or pneumatic force) is applied. Under the action of the external force, the guide rod moves along a predetermined trajectory. When the guide rod reaches the target position, it triggers the device to open the openings of the first and second dispensing chambers 3. This method is suitable for applications requiring precise control of the opening time and sequence.

[0050] The guide rod can also move through thermal deformation. It can be made of a thermally responsive material that deforms when the temperature rises or falls. By heating or cooling the guide rod, it can deform during temperature changes and move along a predetermined path. When the guide rod reaches the target position, the openings of the first and second dispensing chambers 3 can also be opened. This design is particularly effective in special environments, such as situations where the detergent dispensing amount needs to be automatically adjusted according to temperature changes.

[0051] In a preferred embodiment of the present invention, the movable component 1 in the detergent dispensing device is a deformable guide rod. This guide rod is made of a thermally responsive material. When the material is energized, it generates heat and expands, causing the guide rod to deform and move along a predetermined trajectory. When the guide rod moves to the target position, it simultaneously opens the openings of the first dispensing chamber 2 and the second dispensing chamber 3, releasing detergent into the device.

[0052] This design, which uses electrical heating to induce material expansion, provides precise control, ensuring the dispensing chamber opens accurately when needed. Because the material is highly sensitive to temperature changes, the movement distance and speed of the guide rod can be precisely adjusted by controlling the current and the duration of energization, thus adapting to the dispensing requirements of different types of detergents and equipment. This design is simple and reliable, making it particularly suitable for use in washing equipment requiring highly automated control.

[0053] In addition, the guide rod can also be moved by a motor. In this method, the guide rod is connected to a motor, which controls its movement path and position. When the motor starts, the guide rod is precisely driven to the target position, thereby opening the openings of the first and second dispensing chambers. The motor-driven method provides a highly controllable movement process, suitable for scenarios requiring precise control of detergent dispensing time and sequence.

[0054] Alternatively, the guide rod can also be moved using a magnetic field. A magnetically responsive material can be installed on the guide rod; when an external magnetic field is applied, the guide rod will move under the influence of the magnetic force. By adjusting the strength and direction of the magnetic field, the movement of the guide rod can be precisely controlled. When the guide rod reaches the target position, the openings of the two delivery chambers will open. This magnetic field-driven method is particularly suitable for applications requiring contactless control, enabling remote or automated control.

[0055] In one embodiment of this invention, the movable component 1 of the detergent dispensing device is designed to move relative to the first dispensing chamber 2 and the second dispensing chamber 3. In its initial position, the movable component 1 blocks the opening of the first dispensing chamber 2 to prevent premature detergent leakage. When the device is activated, the movable component 1 moves along a preset trajectory. When the movable component 1 reaches the target position, the opening of the first dispensing chamber 2 is opened, thereby releasing the detergent.

[0056] At the same time, as the moving part 1 moves, the opening of the second dispensing chamber 3 is also gradually opened. This design ensures that the openings of the two dispensing chambers can open sequentially or simultaneously to achieve precise dispensing of different detergents.

[0057] In another embodiment of this invention, the device may further include a transmission member 31 for controlling the opening of the second dispensing chamber 3. When the moving member 1 is connected to the transmission member 31 during movement, it drives the transmission member 31 to move together, thereby opening the opening of the second dispensing chamber 3. This design allows for coordinated control of the openings of the two dispensing chambers through a single movement of the moving member 1, enabling the detergent to be accurately dispensed at the appropriate time, thus improving the device's efficiency and cleaning effect.

[0058] The introduction of a transmission component in this embodiment increases the complexity of the system, but it also provides a more flexible control method, enabling better adjustment and separation of the opening operations of the two delivery chambers.

[0059] Furthermore, as one embodiment of this invention, the detergent dispensing device further includes a transmission member 31 for controlling the opening of the second dispensing chamber 3. The sidewall of the first dispensing chamber 2 is made of a deformable material, and the transmission member 31 is disposed adjacent to the outside of the first dispensing chamber 2.

[0060] When the movable component 1 moves to the target position, it presses against the side wall of the first dispensing chamber 2, causing the side wall to deform. This deformation of the side wall drives the transmission component 31 to move, thereby opening the second dispensing chamber 3. This design utilizes the movement of the movable component 1 to simultaneously control the opening of two dispensing chambers, thus achieving multi-chamber synchronous control.

[0061] Alternatively, as another implementation, the transmission member 31 is sealed and passes through the first dispensing cavity 2. The moving member 1 directly contacts and drives the transmission member 31 during movement. When the moving member 1 moves to the target position, the transmission member 31 is pushed to the designated position, thereby opening the opening of the second dispensing cavity 3.

[0062] In this design, the transmission component is located outside the first dispensing chamber and adjacent to its sidewall. The movement of the moving component acts directly on the sidewall of the first dispensing chamber. When the sidewall is compressed and deformed, this deformation causes the external transmission component to move, thereby opening the second dispensing chamber. This design, which utilizes the deformation of the sidewall to transmit power, is an indirect control method.

[0063] Furthermore, in one embodiment of this invention, the movable component 1 of the detergent dispensing device is sealed and passes through the first dispensing chamber 2. When the device is in its initial state, the movable component 1 blocks the opening of the first dispensing chamber 2, ensuring that the detergent does not leak prematurely. As the movable component 1 moves along a preset trajectory, it gradually disengages from the opening of the first dispensing chamber 2, thereby opening the opening of the first dispensing chamber 2 and releasing the detergent into the device.

[0064] Simultaneously, as the moving part 1 moves, the opening of the second dispensing chamber 3 is also opened, allowing a second type of detergent to be dispensed into the device. This design ensures that the openings of both dispensing chambers can be opened simultaneously, enabling the simultaneous dispensing of multiple detergents.

[0065] In this method, the transmission component passes through the sidewall of the first dispensing chamber and is sealed within it. The movement of the movable component directly acts on the transmission component, driving it to move and thus opening the opening of the second dispensing chamber. Control here is more direct; without relying on deformation of the sidewall, the transmission component directly contacts and controls the openings of the two dispensing chambers through the sealed passage.

[0066] Furthermore, in another embodiment, at least one sidewall of the first dispensing chamber 2 is a deformable structure. When the moving member 1 moves, it compresses this sidewall, causing it to deform outward. This deformation opens the opening of the second dispensing chamber 3, thereby releasing the second detergent. By simultaneously controlling the openings of both chambers using the movement of the moving member 1, the device of the present invention achieves efficient and accurate detergent dispensing, making it suitable for washing equipment requiring complex dispensing sequences, such as dishwashers.

[0067] Furthermore, the detergent dispensing device includes a housing, with both the first dispensing chamber 2 and the second dispensing chamber 3 disposed inside the housing. The openings of the first dispensing chamber 2 and the second dispensing chamber 3 are located at the bottom of the housing to facilitate detergent discharge.

[0068] The movable component 1 is also disposed within the housing and is movable relative to the first delivery chamber 2 and the second delivery chamber 3. In order to control the movement of the movable component 1, a control module is also provided on the top of the housing. The control module is connected to the movable component 1 and is used to control the movement trajectory and position of the movable component 1.

[0069] This design integrates two dispensing chambers and the moving part 1 into a compact housing, which not only protects the components from external environmental influences but also makes the device more compact, facilitating integration and use in various washing equipment. Precise control via the control module enables accurate detergent dispensing, ensuring washing effectiveness and equipment efficiency.

[0070] Furthermore, the movable part 1 of the detergent dispensing device is provided with an opening part 11. This opening part 11 is spaced apart from the front end of the movable part 1. When the movable part 1 is in its initial position, the opening part 11 is located inside the housing and is not aligned with the opening of the dispensing chamber, thereby maintaining the sealing of the dispensing chamber.

[0071] When the device is started and the moving part 1 is controlled to move along a predetermined path, the opening part 11 on the moving part 1 gradually enters the first dispensing chamber 2, and as the moving part 1 continues to move, it eventually aligns with the openings of the first dispensing chamber 2 and the second dispensing chamber 3. At this time, the opening part 11 simultaneously opens the openings of the two dispensing chambers, allowing detergent to be released from both dispensing chambers into the washing equipment at the same time.

[0072] This design cleverly achieves the synchronous opening of multiple dispensing chambers by setting an opening part 11 on the moving part 1, thereby improving the working efficiency of the device. It is suitable for washing equipment that requires precise control of detergent dispensing in multiple chambers, such as dishwashers. By setting an interval, the opening part 11 can ensure the accuracy and reliability of dispensing during its movement between the initial and target positions.

[0073] In one embodiment of this invention, the movable part 1 of the detergent dispensing device is provided with an opening portion 11, which may be a groove formed on the side wall of the movable part 1. When the movable part 1 moves to the target position, the groove aligns with the opening of the first dispensing chamber 2, thereby opening the openings of the first dispensing chamber 2 and the second dispensing chamber 3 simultaneously, ensuring that the detergent can be released synchronously.

[0074] In another embodiment of this invention, the moving part 1 is configured with a variable diameter, meaning the diameter of the moving part 1 gradually decreases along its length. The further away from the front end of the moving part 1, the smaller the diameter of the opening part 11. This allows the moving part 1 to smoothly enter and open the opening of the first delivery chamber 2 when the guide rod moves to the target position. At this time, the openings of the first delivery chamber 2 and the second delivery chamber 3 can open simultaneously, achieving synchronous delivery.

[0075] Preferably, the opening portion 11 is formed around the side wall of the guide rod. This surrounding design ensures that the opening portion 11 is aligned with the opening of the dispensing chamber regardless of the direction in which the moving part 1 moves, thus achieving reliable synchronous opening. This design not only improves the dispensing accuracy of the dispensing device but also simplifies the structure, making the device more suitable for application in various washing equipment, such as dishwashers.

[0076] Furthermore, the detergent dispensing device includes a retraction device 4 for providing a restoring force to the moving part 1. One end of the retraction device 4 is fixed to the housing, and the other end is fixed to the moving part 1. After the moving part 1 completes the dispensing action, the retraction device 4 automatically applies force to restore the moving part 1 to its initial position, ensuring that the device is ready for the next dispensing operation.

[0077] Preferably, the other end of the shrinking device 4 is fixed near the opening part 11 of the moving part 1, so that the opening part 11 can be separated from the opening of the dispensing chamber more directly and effectively, thereby restoring the sealing state of the dispensing chamber and preventing the remaining detergent from continuing to leak.

[0078] The retraction device 4 can be arranged around the outer periphery of the moving part 1. This design allows the retraction device 4 to provide a reset function within a limited space, while protecting the retraction device 4 from external damage. In addition, multiple limiting structures can be provided around the outer periphery of the moving part 1. The limiting structures work in conjunction with the retraction device 4 to limit the range of movement of the moving part 1, ensuring that it can only move within a predetermined trajectory.

[0079] Furthermore, a channel can be provided inside the moving part 1, and the shrinking device 4 is housed within this channel. This internal channel design allows the shrinking device 4 to be better concealed and protected, while maintaining the compact external structure of the moving part 1. This design optimizes the overall structure of the detergent dispensing device, making it suitable for application in various washing machines.

[0080] To achieve the reset function of the movable part 1, an elastic element such as a spring or rubber band can be further provided. Specifically, one end of the spring or rubber band is fixed to the housing, and the other end is connected near the movable part 1, particularly near the opening part 11. When the movable part 1 moves to the target position and completes the opening under energization or force, the spring or rubber band applies a reverse pulling force, resetting the movable part 1 to its initial position. This reset mechanism not only simplifies the operation of the device but also ensures that the movable part 1 is reset promptly after each deployment, ready for the next operation.

[0081] Springs provide a stable and controllable restoring force, making them suitable for applications requiring precise control of the restoring speed. Rubber bands, on the other hand, offer a wider range of elasticity and restoring force, making them suitable for applications requiring greater movement or faster restoring. Depending on the specific application requirements, a suitable elastic element can be selected to ensure optimal device performance.

[0082] Through the above design, the detergent dispensing device of the present invention can not only accurately control the dispensing of detergent, but also automatically reset and prepare for the next dispensing, thereby improving the efficiency and ease of operation of the equipment.

[0083] The dishwasher described in this invention employs the detergent dispensing device as previously described. This detergent dispensing device allows the dishwasher to precisely control the dispensing time and amount of detergent, thereby improving cleaning performance.

[0084] Specifically, the dishwasher's control system can connect to the control module of the dispensing device, precisely controlling the movement of the moving part 1 through a preset program to achieve on-demand dispensing of different detergents. For example, at different stages of the washing process, the dishwasher can sequentially or simultaneously open the first dispensing chamber 2 and the second dispensing chamber 3, releasing a predetermined amount of detergent. This precise control method not only improves detergent utilization but also adapts to the cleaning needs of different types of tableware.

[0085] Furthermore, the dishwasher employing this dispensing device is more compact in structure, reducing its footprint within the interior space. Simultaneously, through optimized design, it lowers overall manufacturing costs and energy consumption. With this innovative detergent dispensing device, the dishwasher of this invention provides a more efficient and environmentally friendly cleaning solution, meeting users' dual needs for cleaning effectiveness and ease of use.
