Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and more specifically, relates to a washing machine. Background Technology

[0002] Washing machines are machines that use electric power to generate mechanical force to clean clothes. For clothes such as shirts, the collar and cuffs are generally dirtier than other areas. However, existing washing machines are not very effective at cleaning these areas during the washing process.

[0003] In existing technologies, ultrasonic washing is often required to achieve the desired result by adding an ultrasonic washing function to the washing machine.

[0004] For example, Chinese Patent Application No. CN200520069251.1 discloses a washing machine with a local ultrasonic washing device, including a washing machine body and an ultrasonic washing device. The ultrasonic washing device consists of an ultrasonic generator, a transducer, a device housing, and a transducer base. The ultrasonic generator is installed in a computer board and connected to the transducer. The transducer is installed on the base inside the device housing and is pressed down by a cover plate. The ultrasonic washing device is fixed by a positioning support and is installed at the rear of the washing machine's worktable via the positioning support.

[0005] Chinese patent application number CN2017101131757 discloses a partial cleaning structure for clothing and a washing machine. The partial cleaning structure for clothing is detachably mounted on the washing machine tray and connected to the washing machine's water inlet / detergent box. The partial cleaning structure for clothing includes a pressure plate and a support plate. The pressure plate includes an ultrasonic transducer, and the support plate includes a water inlet cavity. The shape of the pressure plate matches the support plate. After being pressed towards the support plate, a narrow slit is formed between them to clamp the part of the clothing to be washed, clamping the clothing and ultrasonically cleaning the part to be washed.

[0006] While the above solution addresses the issue of washing machines being unable to clean heavily soiled areas to some extent, it also presents challenges for washing machines that automatically dispense detergent. This requires both a foam generator and a separate detergent dispenser on the tray, but the limited space within the washing machine tray makes it impossible to properly accommodate both.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine in which the detergent box and the foam generating device are arranged in the same receiving cavity in the tray base. The inner wall of the clothes loading port has an opening that communicates with the receiving cavity. The detergent box can be pulled out through the opening for detergent replenishment. The detergent box and the foam generating device are convenient to use, have a simple structure, and occupy little space.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a washing machine, comprising,

[0010] A tray base has a clothing inlet, the inner wall of which has an opening, and the tray base has a receiving cavity communicating with the opening;

[0011] A detergent dispenser is disposed within the receiving cavity;

[0012] A foam generating device for producing detergent foam is disposed in the receiving cavity.

[0013] This invention provides an opening on the inner wall of the garment inlet of a detergent dispenser base, and a receiving cavity communicating with the opening within the base. Both the detergent dispenser and the foam generating device are housed within this receiving cavity. This design facilitates user access to the foam generating device from the garment inlet and allows the user to easily pull the detergent dispenser out through the opening to replenish detergent. Furthermore, the simple structure of housing the detergent dispenser and the foam generating device within the receiving cavity allows for efficient allocation of space within the detergent dispenser base and saves valuable space.

[0014] Furthermore, the detergent dispenser is movable inside and outside the receiving cavity, and the foam generating device is fixed inside the receiving cavity.

[0015] Furthermore, the foam generating device has a nozzle, which is disposed on the bottom wall of the receiving cavity near the opening, and the nozzle extends downward through the bottom wall of the receiving cavity.

[0016] Furthermore, one side of the detergent dispenser is sealed or the opening is left open.

[0017] Furthermore, a panel is provided on one side wall of the detergent box, and an extension plate is provided extending laterally outward along the panel. The extension plate is disposed opposite to the foam generating device, and the panel and the extension plate seal the opening.

[0018] Furthermore, the detergent dispenser is movable inside and outside the receiving cavity, and the foam generating device is disposed on the detergent dispenser for moving inside and outside with the detergent dispenser.

[0019] Furthermore, the detergent dispenser has multiple placement areas, and the foam generating device is located in one of the placement areas of the detergent dispenser.

[0020] Furthermore, the bottom wall of the receiving cavity is provided with a notch that communicates with the opening;

[0021] The foam generating device has a nozzle that extends downward through the bottom wall of the detergent box and is located in the notch, for use when the detergent box moves outward through the notch to the outside of the receiving cavity.

[0022] Furthermore, it also includes a liquid storage box, which is disposed inside the detergent box, and a one-way valve is provided between the liquid storage box and the foam generating device for guiding the detergent in the liquid storage box to the foam generating device in one direction.

[0023] Furthermore, it also includes a liquid storage box, which is disposed in the tray base, and a connecting pipe is provided between the liquid storage box and the foam generating device for guiding the detergent in the liquid storage box to the foam generating device.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] (1) The present invention provides an opening on the inner wall of the clothing inlet of the tray base and a receiving cavity communicating with the opening in the tray base. The detergent box and the foam generating device are both placed in the receiving cavity. On the one hand, it is convenient for the user to use the foam generating device from the clothing inlet and to pull the detergent box out from the opening to replenish the detergent. On the other hand, the detergent box and the foam generating device are placed in the receiving cavity. The structure is simple, can reasonably allocate the space in the tray base, and save space.

[0026] (2) By setting the foam generating device on the detergent box, when the detergent box is pulled out of the receiving cavity, the foam generating device is moved to the top of the washing tub opening, so that the user can receive the detergent foam sprayed from the foam generating device, and can ensure that excess detergent foam or detergent foam that falls off the user's clothes can fall accurately into the washing tub, making it convenient for the user to use the foam generating device.

[0027] (3) By providing a notch on the bottom wall of the receiving cavity that communicates with the opening, the present invention can avoid the nozzle of the foam generating device extending downward. When the nozzle moves outward with the detergent box, it can move to the outside of the receiving cavity through the notch and the opening. When the nozzle retracts inward with the detergent box, the nozzle can move to the notch through the opening without collision.

[0028] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0042] like Figures 1 to 7 As shown, the present invention provides a washing machine, which includes a tray base 1, a detergent box 2, and a foam generating device 3.

[0043] The tray base 1 is disposed at the upper part of the washing machine. The tray base 1 has a clothes loading port 11 for loading or unloading clothes into or from the washing machine. The inner wall of the clothes loading port 11 has an opening 12. The tray base 1 has a receiving cavity 13, which communicates with the opening 12.

[0044] The detergent dispenser 2 is disposed in the receiving cavity 13. The foam generating device 3, used to generate detergent foam, is disposed in the receiving cavity 13.

[0045] This invention provides an opening 12 on the inner wall of the clothing dispensing port 11 of the tray base 1, and a receiving cavity 13 communicating with the opening 12 within the tray base 1. Both the detergent box 2 and the foam generating device 3 are placed in the receiving cavity 13. This design facilitates the user's use of the foam generating device 3 through the clothing dispensing port 11 and allows the user to easily pull the detergent box 2 out through the opening 12 to replenish detergent. Furthermore, the design features a simple structure, efficient allocation of space within the tray base 1, and space-saving functionality.

[0046] like Figures 2 to 4 As shown, in one embodiment, the detergent box 2 is movable inside and outside in the receiving cavity 13, and the foam generating device 3 is fixed in the receiving cavity 13.

[0047] In this invention, the foam generating device 3 is fixed in the receiving cavity 13, and the detergent box 2 is movably disposed in the receiving cavity 13. The use of the foam generating device 3 is not affected by the movement of the detergent box 2 inside and outside.

[0048] Furthermore, the foam generating device 3 has a nozzle 31 for spraying the generated detergent foam outside the foam generating device 3. The nozzle 31 is disposed on the bottom wall of the receiving cavity 13 near the opening 12, and the nozzle 31 extends downward through the bottom wall of the receiving cavity 13.

[0049] Because the nozzle 31 is located on the side of the receiving cavity 13 near the opening 12 and extends downward through the bottom wall of the receiving cavity 13, the user can receive the detergent foam generated by the foam generating device 3 from below the opening 12, regardless of whether the detergent box 2 is moved or pulled out. Furthermore, the detergent box 2 is pull-out within the receiving cavity 13 through the opening 12, making it convenient for the user to add detergent to the detergent box 2.

[0050] The opening 12 is either blocked or opened on one side of the detergent dispenser 2. This invention utilizes one side of the detergent dispenser 2 to open the opening 12 when the detergent dispenser 2 is pulled out of the receiving cavity 13, and to block the opening 12 on the inner wall of the clothing dispensing port 11 when the detergent dispenser 2 is retracted into the receiving cavity 13, thus concealing the foam generating device 3 and improving the appearance.

[0051] The detergent dispenser 2 and the foam generating device 3 are arranged sequentially in the receiving cavity 13 along the circumference of the clothing dispensing port 11.

[0052] A panel 21 is provided on one side wall of the detergent box 2, and an extension plate 22 is formed by extending laterally outward along the panel 21. The extension plate 22 is arranged opposite to the foam generating device 3, and the panel 21 and the extension plate 22 are sealed in the opening 12.

[0053] When the detergent dispenser 2 retracts into the receiving cavity 13, the panel 21 and the extension plate 22 are located within the opening 12. The outer surfaces of the panel 21 and the extension plate 22 are flush with the inner wall of the clothing inlet 11 around the opening 12.

[0054] The nozzle 31 of the foam generating device 3 is positioned close to the extension plate 22.

[0055] Furthermore, a door lock module is provided between the detergent dispenser 2 and the tray base 1. The upper end of the panel 21 and the upper end of the extension plate 22 protrude upward from the side wall of the detergent dispenser 2. A door lock is provided at the upper end of the opening 12, and a matching latch is provided on the upper end of the panel 21 near the receiving cavity 13 or on the upper end of the extension plate 22 near the receiving cavity 13. The detergent dispenser 2 is locked to the door lock in the opening 12 by the latch.

[0056] A push-button lock is provided between the detergent box 2 and the tray base 1.

[0057] Furthermore, the washing machine also includes a liquid storage box 4, which is disposed within the receiving cavity 13. The liquid storage box 4 is connected to the foam generating device 3 via a connecting pipe 42.
