Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to an automatic dispensing device and a clothing processing device. Background Art

[0002] Traditional washing machines only determine the water intake and the amount of detergent and softener to be added by detecting the weight of the clothes. When the detergent is a high-foaming and high-activity product, it is easy for the controller to over-judge the detergent dosage, resulting in excessive foam. This will cause the washing machine to have excessive damping during washing, causing the motor to stall, and may also cause foam residue on the clothes that cannot be cleaned. Even after rinsing, foam residue will appear on the door seal of the washing machine, causing the washing machine door to be unable to open normally, affecting the user experience. Utility Model Content

[0007] In some embodiments, the automatic dispensing device also includes a liquid level sensor, which is arranged on the inner wall of the accommodating cavity. The driving pump is also connected to a water source. When the liquid level of the detergent is lower than the detection level of the liquid level sensor, the driving pump is used to pump water into the accommodating cavity so that the detergent and water are mixed to form foam. The detection component is used to detect the foam to obtain the active agent concentration of the detergent.

[0008] In some embodiments, the top wall of the detergent box has a mounting recess, and the detection assembly is detachably mounted in the mounting recess.

[0009] In some embodiments, a bottom wall of the mounting recess is provided with a slide groove, and an outer surface of the detection component has a connector, and the connector can be slidably inserted into the slide groove.

[0010] In some embodiments, a mounting hole is provided on the bottom wall of the mounting recess, and the mounting hole is located in the extension direction of the slide groove. A snap fastener is provided on the surface of the detection component corresponding to the mounting hole, and when the connector slides to the end of the slide groove, the snap fastener is engaged with the mounting hole.

[0011] In some embodiments, the detergent box is provided with a pipe outlet, the driving pump has a water outlet pipe, the water outlet pipe passes through the pipe outlet and extends to the bottom of the accommodating cavity, and the mounting recess is provided near the pipe outlet.

[0012] In some embodiments, the detection component is an infrared spectrometer, an energy spectrometer, or a liquid chromatography-mass spectrometer.

[0028] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0029] On the one hand, an embodiment of the present application provides an automatic dispensing device, which is applied to a washing machine. The automatic dispensing device includes a detergent box 1, a detection component 2: the detergent box 1 and a driving pump 3. The detergent box 1 is provided with a accommodating cavity 11, which is used to store detergent; the detection component 2 is installed in the accommodating cavity 11, and is used to detect the concentration of the active agent in the detergent; the driving pump 3 is arranged on the connecting pipe between the detergent box 1 and the washing tub, and the driving pump 3 is used to pump the detergent in the detergent box 1 into the washing tub according to the detection result of the detection component 2.

[0030] In the embodiment of the present application, the composition of the detergent stored in the detergent box 1 is detected by the detection component 2, and the concentration of the active agent in the detergent is detected. The amount of detergent added by the driving pump 3 is adjusted according to the detection result. If the concentration of the active agent is high, less detergent is added into the washing tub. If the concentration of the active agent is low, more detergent is added accordingly. This setting can ensure that the amount of detergent added to the washing tub is appropriate, avoiding the situation where the active agent concentration is too high and causes excessive foam after washing. In this way, it can be ensured that no foam will remain on the clothes after washing is completed, thereby ensuring that the washing machine with the automatic dispensing device can be used normally.

[0031] In some embodiments, the automatic dispensing device also includes a liquid level sensor, which is arranged on the inner wall of the accommodating chamber 11. The driving pump 3 is also connected to the water source. When the liquid level of the detergent is lower than the detection level of the liquid level sensor, the driving pump 3 is used to pump water into the accommodating chamber 11 so that the detergent and water are mixed to form foam. The detection component 2 is used to detect the foam to obtain the active agent concentration of the detergent.

[0032] Specifically, the liquid level sensor is used to detect the detergent content. The liquid level sensor is arranged on the inner peripheral wall of the detergent box 1 and is arranged near the bottom wall. The height of the liquid level sensor is the height of the detection liquid level. When the detergent liquid level is lower than the detection liquid level, the pump 3 is driven to add some water into the detergent box 1 so that the overall liquid level in the detergent box 1 is higher than the detection liquid level. When the detergent and part of the water are mixed, a large amount of foam is generated. At this time, the detection component 2 can obtain the concentration of the active agent in the detergent by detecting the foam, and then determine the amount of detergent to be added to the washing tub. When the detergent liquid level is higher than the detection liquid level, the detection component 2 can directly detect the detergent and pump the detergent into the washing tub by driving the pump 3. This arrangement ensures that the automatic dispensing device can detect the active agent concentration of the detergent even if the user does not replenish the detergent content in time. When the detergent liquid level is too low, an alarm can be issued to alert the user. In this way, the automatic dispensing device can adapt to various working conditions, improving the universality of washing machines equipped with the automatic dispensing device.

[0033] In some embodiments, the top wall of the detergent box 1 has a mounting recess, and the detection assembly 2 is detachably mounted in the mounting recess.

[0034] Specifically, a mounting recess is provided on the top wall of the detergent box 1. The mounting recess has an installation indicator. This arrangement provides a fool-proof design that facilitates assembly by the assembler. The detection assembly 2 detects the detergent from top to bottom, making it less likely to be contaminated by the detergent. The detachable configuration of the detection assembly 2 facilitates subsequent replacement or maintenance, and different models of detection assemblies 2 can be selected for installation according to different machine models. In other embodiments, the detergent box 1 is fixedly mounted in the mounting recess.

[0035] In some embodiments, a slide groove is provided on the bottom wall of the mounting recess, and a plug-in component is provided on the outer surface of the detection component 2 , and the plug-in component can be slidably inserted into the slide groove.

[0036] Specifically, a slide groove is provided on the bottom wall of the mounting recess, which extends along the front-to-back direction of the detergent box 1. The sliding entrance and the sliding exit of the slide groove are shared, that is, the connector cannot slide out from the end of the slide groove. A connector is protruding from the surface of the detection component 2. The connector is T-shaped. The connector enters the slide groove from the sliding entrance. The connector is limited by the slide groove so that the connector cannot move in the up and down directions and thus detach from the slide groove, but can slide in the length direction of the slide groove. This arrangement makes the detection component 2 easy to install and is not easy to fall off from the slide groove during normal use.

[0037] In some embodiments, a mounting hole is provided on the bottom wall of the mounting recess, and the mounting hole is located in the extension direction of the slide groove. A snap fastener is provided on the surface of the detection component 2 corresponding to the mounting hole. When the connector slides to the end of the slide groove, the snap fastener is engaged with the mounting hole.

[0038] Specifically, a mounting hole is provided at the end of the chute. When the detection component 2 slides to the end of the chute, the latch is engaged in the mounting hole, thereby limiting the continued movement of the connector. This arrangement can further increase the installation stability of the detection component 2, ensuring that the detection component 2 is not easily dropped from the mounting recess during use. In some other embodiments, a magnetic protrusion protrudes outward from the outer edge of the detection component, and a magnetic element is provided on the top wall of the detergent box 1. The magnetic element is provided at the end of the chute. When the detection component 2 slides to the end of the chute, the magnetic protrusion is magnetically connected to the magnetic element.

[0039] In some embodiments, the detergent box 1 is provided with a pipe opening 15 , the driving pump 3 has a water outlet pipe 34 , the water outlet pipe 34 passes through the pipe opening 15 and extends to the bottom of the accommodating cavity 11 , and the mounting recess is provided near the pipe opening 15 .

[0040] Specifically, a pipe opening 15 is provided on one side of the detergent box 1. The outlet pipe 34 of the driving pump 3 passes through the pipe opening 15 and extends into the bottom of the accommodating chamber 11. In this way, when the driving pump 3 pumps water into the detergent box 1, the water can immediately mix with the detergent at the bottom of the detergent box 1. The mounting recess is located near the pipe opening 15, so that the detection component 2 is close to the opening of the outlet pipe 34. With this arrangement, the foam generated by the mixing of detergent and water can be promptly detected by the detection component 2, thereby improving detection efficiency and speeding up the washing process of the washing machine. In other embodiments, the mounting recess is located away from the pipe opening 15.

[0041] In some embodiments, the detection component 2 is an infrared spectrometer, an energy spectrometer, or a liquid chromatography-mass spectrometer.

[0042] Specifically, all three instruments can detect the concentration of active agents in detergents. The infrared spectrometer detects the composition of the detergent by analyzing the absorption of infrared light by molecules in the detergent, thereby obtaining the concentration of the active agent; the energy spectrometer uses the characteristic energy of X-ray photons of different elements to analyze the composition of the detergent. In this embodiment, the detection component 2 is an infrared spectrometer. The infrared spectrometer has a fast analysis speed, does not cause contamination to the active agent, has high detection accuracy, and is low in cost.

[0043] In some embodiments, the detection component 2 is an infrared spectrometer, the detergent box 1 is made of a low-reflection material, and at least one inner wall surface of the accommodating cavity 11 is white.

[0044] Specifically, the inner wall of the detergent box 1 is white, and the detergent box 1 is made of low-reflective material. In this way, during the detection process of the infrared spectrometer, the detergent box 1 will not reflect excess light into the infrared spectrometer, and the white inner wall will not absorb the red light emitted by the spectrometer, thereby ensuring the accuracy of the detection effect of the infrared spectrometer.

[0045] In some embodiments, a partition 12 is provided in the detergent box 1, and the accommodating cavity 11 is divided into a detergent portion 11a and a softener portion 11b by the partition 12. The detection component 2 is installed in the detergent portion 11a, and the driving pump 3 is connected to the detergent portion 11a and the softener portion 11b respectively.

[0046] Specifically, a detection component 2 is only provided in the detergent section 11a for detecting the concentration of the active agent in the detergent. With this arrangement, the detection component 2 will not detect any substance other than the detergent, thereby ensuring the accuracy and singleness of the detection result. The driving pump 3 can pump the softener into the washing tub. Water can also be added to the softener section 11b through the driving pump 3 to mix the remaining softener with the water, and then pumped into the washing tub through the driving pump 3. The detergent box 1 has a top cover 14, and two switchable injection ports 13 are provided on the top cover 14, which are used to inject detergent and softener into the detergent section 11a and the softener section 11b respectively. The detection component 2 is detachably mounted on the inner wall of the top cover 14.

[0047] Furthermore, the driving pump 3 is provided with a connected water inlet pipe 31, two first branches 32 and two second branches 33, and two water outlet pipes 34 are provided. The first branch 32 and the water outlet pipe 34 are connected one-to-one, one water outlet pipe 34 is connected to the detergent part 11a, and the other water outlet pipe 34 is connected to the softener part 11b. The second branch 33 corresponds one-to-one to the first branch 32, and the second branch 33 is used to connect to the washing bucket. The driving pump 3 has two working states. When in the first working state, the first branch 32 is connected to the second branch 33, and the water inlet pipe 31 is disconnected. At this time, the driving pump 3 is used to pump detergent and softener into the washing bucket; when in the second working state, the water inlet pipe 31 is connected to the first branch 32, the second branch 33 is disconnected, and the water inlet pipe 31 is connected to the water source for pumping water into the accommodating chamber 11.

[0048] On the other hand, an embodiment of the present application provides a clothing processing device, including the automatic dispensing device as described above.

[0049] Specifically, the clothing processing device in this embodiment is a washing machine, and an automatic dispensing device is provided in the shell of the washing machine. The automatic dispensing device is used to dispense laundry detergent and softener into the washing tub. The washing machine can preliminarily determine the amount of water and detergent required by detecting the weight of the clothes, and then combine the analysis of the detergent components in the automatic dispensing device to determine the final amount of detergent required to be added, so as to avoid excessive foam after washing.

[0050] The above is a detailed introduction to the automatic dispensing device and clothing processing equipment provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
