The emergence of washing equipment greatly facilitates the life of users and reduces the burden of users.

[0003] Traditional washing equipment is manually added with detergent, that is, the user manually adds detergent before starting the washing equipment. This way of adding detergent is not only difficult to control the amount of detergent added into the washing equipment each time, but also is troublesome when adding, which seriously affects the user experience.

[0004] Recently, some washing equipment with automatic dispensing device has appeared in the market. The washing equipment is provided with a detergent box, so that a certain amount of detergent is stored in the dispensing device. The dispensing device dispenses the detergent in the detergent box into the washing water to realize the automatic dispensing function.

[0005] In order to obtain the real-time amount of detergent in the detergent box, a laser liquid level detection module is additionally provided on the detergent box. However, the existing laser liquid level detection module is generally installed inside the detergent box. Although this arrangement ensures the sealing of the detergent box, it affects the volume of the detergent box, and has high requirements for the sealing of the laser liquid level detection module itself, which is high in sealing cost and is not conducive to maintenance.

The laser liquid level detection module 2 is used to detect the remaining amount of detergent in the detergent box in real time.

[0058] In this embodiment, the detergent dispenser assembly can be used in any washing equipment, such as a washing machine, dishwasher, or garment care machine that requires detergent dispensing. This embodiment uses a washing machine as an example for illustration, but it is not intended to limit the scope of protection.

[0059] In this embodiment, the laser liquid level detection module 2 is communicatively connected to the washing machine's control unit, transmitting the detected detergent level information to the control unit in real time. The control unit can control the user interface to display the detergent level information in real time, and can also control the alarm module to sound an alarm when the detergent level is low. Preferably, in this embodiment, the control unit controls the user interface to display the detergent level in the detergent dispenser in real time.

[0060] In this embodiment, an installation port 11 is provided on the top wall of the detergent box body 1. The laser liquid level detection module 2 is installed at the installation port 11. The laser detection element 221 of the laser liquid level detection module 2 is set perpendicular to the liquid surface of the detergent. The laser detection element 221 emits a laser towards the liquid surface of the detergent, and then receives the laser reflected from the liquid surface. The liquid level height is calculated by the return time to determine the remaining amount of detergent. This is used to remind the user when to add detergent, or to display the remaining liquid value in the automatic detergent box in real time through the user's operation interface.

[0061] In this embodiment, the laser liquid level detection module 2 includes a light-transmitting housing 21 and a PCB board 22 disposed inside the light-transmitting housing 21.

The light-transmitting material can be PMMA or transparent glass.

[0063] In this embodiment, the light-transmitting outer shell 21 is configured as a groove with the opening facing the outside of the detergent box body 1. The PCB board 22 can be installed in the groove of the light-transmitting outer shell 21 by any mounting structure. For example, the PCB board 22 can be fixed in the groove of the light-transmitting outer shell 21 by screws 4, or it can be installed in the groove of the light-transmitting outer shell 21 by a snap-fit ​​structure.

[0099] Preferably, the sealing ridge 31 extends obliquely from the inner wall and / or the outer wall of the sealing ring 3 towards the direction opposite to the mounting direction of the sealing ring 3, so that the sealing ring 3 can elastically abut against the light-transmitting shell 21 and the mounting port 11 to ensure the sealing effect of the gap between the inner wall of the mounting port 11 and the peripheral wall of the light-transmitting shell 21, while ensuring convenient installation.

[0100] Specifically, the sealing ring 3 is mounted in the mounting port 11 from top to bottom, and the sealing ridge 31 on the outer peripheral wall of the sealing ring body extends obliquely from the root to the end towards the top. The light-transmitting shell 21 is inserted into the mounting port 11 from top to bottom, which is equivalent to that the sealing ring 3 is sleeved on the light-transmitting shell 21 from bottom to top, and the sealing ridge 31 on the inner periphery of the sealing ring body extends obliquely from the root to the end towards the bottom. Thus, the installation of the sealing ring 3 is more smooth.

[0101] Further preferably, in the embodiment, the thickness of the sealing ridge 31 gradually decreases from the root to the end, so as to further improve the convenience of installation.

[0102] Preferably, in the embodiment, a light-reflecting block can also be arranged in the detergent box body 1, and the light-reflecting block is arranged corresponding to the laser detection element 221, and the light-reflecting block can float with the change of the liquid level of the detergent. By arranging the light-reflecting block, the working stability of the laser liquid level detection module 2 can be further improved.

[0103] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with equivalent embodiments within the scope of the technical solutions of the present application. The embodiments in the above-mentioned embodiments can be further combined or replaced, as long as they do not deviate from the technical solutions of the present application. Any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application are still within the scope of the present application.
