Description

[0002] With the development of automation technology, home appliances such as garment processing equipment are becoming increasingly intelligent. Existing washing machines are typically equipped with a garment additive dispensing module. This module usually has multiple liquid reservoirs containing various additives such as detergent, fabric softener, and disinfectant to provide more suitable treatment for different types of clothing. The additive dispensing module typically detects the detergent in the liquid reservoirs by adding various labels to the reservoirs to identify the type of additive being added.

[0003] Patent application number 201810179883.5 discloses an automatic detergent additive dispensing device, including a container for holding detergent additives and a mounting part for supporting the container. The container is removably disposed within the mounting part. The device also includes at least one set of liquid level detection structures for detecting the liquid level inside the container. The liquid level detection structure includes a probe, which is a conductive probe, and a conductive part connected to a circuit. One end of the probe is sealed and inserted into the container, and the other end contacts the conductive part to conduct the circuit when the container is placed in the mounting part. When the container is removed from the mounting part, the circuit is disconnected from the conductive part.

[0004] The automatic detergent additive dispensing device disclosed in the above application detects the remaining amount of detergent additive in the container by setting a conductive probe inside the container. However, the container (liquid storage box) for holding detergent additive is difficult and costly to manufacture, and there are few detection or identification methods set on non-liquid storage boxes in the existing technology. Therefore, there is a need for a detection or identification technology that is not directly set on the liquid storage box, so as to reduce the manufacturing cost and difficulty of the liquid storage box.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0017] The annular connecting wall is provided with a first through hole for the probe end of the conductive probe to extend out. The probe end of the conductive probe extends out of the first through hole to the outside of the liquid guiding connector and contacts the additive in the liquid storage box.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The present invention will be further described in detail below with reference to the embodiments.

[0047] like Figures 1 to 8 As shown, the present invention provides a liquid guiding insertion structure, which is disposed on the additive dispensing module. It can be inserted into the liquid storage box 1 through the dispensing port of the liquid storage box 1 and communicate with the additive inside. The liquid guiding insertion structure is provided with a detection device for detecting the type and / or the remaining amount of the additive in the liquid storage box 1.

[0048] Example 1

[0049] like Figures 1 to 5 As shown, this embodiment provides a liquid guiding insertion structure, which is provided with two conductive probes 24 that are in contact with and connected to the additive in the liquid storage box 1. The type and / or balance of the additive in the liquid storage box 1 can be inferred based on the conductivity information of the two conductive probes 24 after they are energized.

[0050] Specifically, the liquid guiding connector structure includes a liquid guiding connector 2 that can be inserted into the liquid storage box 1 through the dispensing port of the liquid storage box 1, and a conductive probe 24 is fixedly disposed on the liquid guiding connector 2.

[0051] One end of the conductive probe 24 is a probe end 241 for detecting the type and / or the remaining amount, and the other end is a terminal 242 for connecting to an external detection circuit. The probe end 241 of the conductive probe 24 extends into the liquid guiding connector 2 and / or the liquid storage box 1.

[0052] Preferably, the conductive probe 24 is embedded or attached to the inner wall of the liquid-conducting connector 2.

[0053] The two conductive probes 24 are set at a certain distance apart. When the probe end 241 comes into contact with the additive, the two energized conductive probes 24 and the additive form a closed circuit. Since different types of additives have different conductivity, the type of additive in the liquid storage box 1 can be inferred by detecting the conductivity.

[0054] When the amount of additive in the reservoir 1 is insufficient, at least one of the two conductive probes 24 cannot come into contact with the additive, that is, a stable closed circuit cannot be formed. At this time, the conductivity is zero, and it can be deduced that the amount of additive in the reservoir 1 is insufficient.

[0055] Furthermore, the liquid guiding connector 2 includes a liquid guiding tube section 21 and a connector section 22 with a reduced outer diameter connected to the end of the liquid guiding tube section 21. The side wall of the connector section 22 is provided with a liquid guiding port 28, through which the additive flows into the liquid guiding connector 2.

[0056] In one embodiment, one end of the liquid guiding tube segment 21 is connected to the additive dispensing module, and the other end is connected to the insertion tube segment 22. The conductive probe 24 is disposed inside the liquid guiding tube segment 21, which has a flow guiding channel 27. The detection end 241 of the conductive probe 24 is located inside the flow guiding channel 27.

[0057] Preferably, the detection ends 241 of the two conductive probes 24 are respectively located at the two ends furthest apart in the radial direction of the flow channel 27, which can effectively prevent misjudgment caused by the two conductive probes 24 and the residual additive forming a closed circuit due to the residue of additive at the bottom of the flow channel 27.

[0058] More preferably, two conductive probes 24 are embedded in the wall of the liquid-conducting connector 2, wherein the probe end 241 is flush with the inner wall of the liquid-conducting connector 2, which can better prevent the residue of additives in the liquid-conducting connector 2 and enhance the durability of the liquid-conducting connector 2.

[0059] In another embodiment, the liquid guiding tube segment 21 extends inward near the port edge of the insertion tube segment 22, forming an annular connecting wall 25 connected to the circumferential edge of the port of the insertion tube segment 22.

[0060] Preferably, the annular connecting wall 25 is provided with a plurality of reinforcing ribs 23 connecting the liquid guiding tube section 21 and the insertion tube section 22. The setting of the reinforcing ribs 23 can make the connection between the liquid guiding tube section 21 and the insertion tube section 22 more stable.

[0061] The annular connecting wall 25 is provided with a first through hole for the probe end 241 of the conductive probe 24 to extend out. The probe end 241 of the conductive probe 24 extends out of the first through hole to the outside of the liquid guiding connector 2 and contacts the additive in the liquid storage box 1.

[0062] Furthermore, the conductive probe 24 is wrapped with a protective layer of rubber material, which not only protects the conductive probe 24 but also fills the gap between the conductive probe 24 and the first through hole, making the connection between the conductive probe 24 and the liquid-conducting connector 2 more stable.

[0063] Preferably, the two conductive probes 24 are respectively disposed on both sides of the reinforcing rib 23. Through the isolation effect of the reinforcing rib 23, it is possible to prevent the formation of a closed circuit due to a small amount of additive left between the two conductive probes 24 because the distance between the two conductive probes is too short, thereby improving the accuracy of the detection device.

[0064] The wall of the liquid-conducting connector 2 is provided with at least two conductive contacts. The terminal 242 of the conductive probe 24 is connected to the conductive contacts, and the conductive contacts are connected to an external detection circuit.

[0065] Preferably, the conductive contact is disposed outside the wall of the liquid-conducting connector 2; or, it is embedded inside the wall of the liquid-conducting connector 2, with at least a portion exposed outside the wall of the liquid-conducting connector 2.

[0066] The conductive contact pad allows the conductive probe 24 to transmit the detected signal to the external detection circuit more effectively. Furthermore, when the conductive probe 24 malfunctions, it can be more easily disassembled and replaced, thus improving the practicality of the liquid-conducting connector structure.

[0067] In another preferred embodiment, the terminal 242 of the conductive probe 24 directly forms a conductive contact and is connected to an external detection circuit, resulting in a more integrated structure and a more reasonable layout.

[0068] The wall of the liquid guiding connector 2 is provided with a second through hole through which the terminal 242 of the conductive probe 24 passes. The terminal 242 of the conductive probe 24 extends out through the second through hole and is connected to an external detection circuit.

[0069] Preferably, the liquid guiding insertion structure further includes a protective cover 26 connected to the outer peripheral wall of the liquid guiding insertion tube 2. The protective cover 26 covers the conductive probe 24, and the wiring terminal 242 at the lower end of the conductive probe 24 extends out of the protective cover 26 and connects to an external detection circuit.

[0070] More preferably, the first through hole and the second through hole are connected on the wall of the liquid-conducting connector 2, and the probe end 241 of the conductive probe 24 extends out of the first through hole, and the terminal 242 extends out of the second through hole. The arrangement of the first and second through holes makes the installation of the conductive probe 24 on the liquid-conducting connector 2 simpler and more convenient, effectively improving the production efficiency of the liquid-conducting connector structure.

[0071] Furthermore, a sealing ring is provided between the first through hole and the second through hole and the peripheral wall of the conductive probe 24.

[0072] With the above settings, the additives in contact can be directly detected by the conductive probe 24, and the information on the type and / or remaining amount of the additives in the liquid storage box 1 can be obtained. There is no need to make special markings on the liquid storage box 1 and other devices, which reduces the manufacturing difficulty and cost of consumables such as the liquid storage box 1.

[0073] Example 2

[0074] This embodiment provides a liquid guide plug structure equipped with a flow detection mechanism. Based on the flow information obtained by the flow detection mechanism, the type and / or remaining amount of the additive in the liquid storage box 1 can be inferred.

[0075] Preferably, the liquid guiding insertion structure includes a liquid guiding insertion pipe 2 that can be inserted into the liquid storage box 1 through the dispensing port of the liquid storage box 1, the liquid guiding insertion pipe 2 having a flow guiding channel 27, and the flow detection mechanism including a flow sensor disposed in the flow guiding channel 27;

[0076] Preferably, the liquid guiding connector 2 includes a liquid guiding tube section 21 and a connector section 22 with a reduced outer diameter at the end of the liquid guiding tube section 21; the flow detection mechanism includes a flow sensor disposed on the outer peripheral wall of the connector section 22 or on the annular connecting wall 25 between the liquid guiding tube section 21 and the connector section 22.

[0077] Specifically, taking the detection of additive categories as an example, while keeping external conditions constant, different types of additives are added multiple times to obtain the corresponding flow sensor speed ranges for each additive, thus generating a category matching table.

[0078] Additives on the market generally include detergents, fabric softeners, and disinfectants. Detergents have the highest viscosity, followed by fabric softeners, and disinfectants have the lowest viscosity. Under the same external conditions, when the additive is detergent, the flow sensor detects the lowest rotational speed, and when the additive is disinfectant, the flow sensor detects the highest rotational speed.

[0079] For example, in the category matching table, the flow meter speed range for detergent is N1-N2, for fabric softener it is N3-N4, and for disinfectant it is N5-N6, where N1 < N2 ≤ N3 < N4 ≤ N5 < N6. Under constant external conditions, by determining the range of the flow meter speed detected by the flow sensor, it can be inferred that the additive is a detergent / fabric softener / disinfectant.

[0080] When the flow sensor detects the remaining amount of additive, under the same external conditions, the flow rate of fluids with lower viscosity, such as air or water, is faster, and the corresponding rotation speed detected by the flow sensor is larger; when additives with higher viscosity flow through, the corresponding rotation speed detected by the flow sensor is smaller.

[0081] Since the additive flows slower than the air when passing through the flow sensor, the addition of the additive can be determined by comparing the rotation speed of the flow sensor. When the rotation speed detected by the flow sensor is high, it can be inferred that the remaining amount of additive is low.

[0082] Specifically, by adding additives multiple times under different margin conditions, a margin matching table for the speed range corresponding to the flow sensor at different margin conditions can be obtained.

[0083] When the additive flows through the flow sensor, the flow sensor detects the rotation speed in real time or at regular intervals. If the detected rotation speed is greater than the rotation speed corresponding to the lowest margin in the margin matching table, it is inferred that the additive margin is insufficient.

[0084] Example 3

[0085] like Figures 6 to 8 As shown, this embodiment provides an additive dispensing module, including a closed chamber liquid storage box 1 for storing additives, a plug-in slot for installing the liquid storage box 1, and the liquid guiding plug-in structure described in the above embodiment. After the liquid storage box 1 is installed into the plug-in slot, the liquid guiding plug-in structure plugs in and opens the dispensing port of the liquid storage box 1 to realize the dispensing of additives.

[0086] Preferably, the liquid storage box 1 is an ink cartridge type liquid storage box 1, and a sealing cap structure 3 is installed at the dispensing port of the liquid storage box 1. Under normal conditions, the dispensing port is closed. The liquid guiding plug structure is inserted into the sealing cap structure 3 to open the dispensing port and allow the additive to be discharged through the liquid guiding plug 2.

[0087] Specifically, when the insertion pipe section 22 is inserted into the sealing cap structure 3, the annular connecting wall 25 and the sealing cap structure 3 form a chamber through which additives flow. The detection device provided on the annular connecting wall 25 detects the additives in the chamber and infers the type and / or amount of additives through the feedback signal obtained from the detection.

[0088] Furthermore, the additive dispensing module is also equipped with a suction device, which is connected to the storage box 1 via the liquid guide pipe 2. Under the action of the suction pump, the additive in the storage box 1 is discharged.

[0090] This embodiment, as a further limitation on all the foregoing embodiments, provides a clothing treatment device. The clothing treatment device is provided with an additive dispensing module as described in the above embodiments between it and a tap water connector, thereby enabling automatic dispensing of additives.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
