Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing devices, and in particular to a liquid storage box, an additive delivery device and a method for identifying the type of additive. Background Art

[0002] At present, the dispensing device for washing machines is gradually emerging, but the existing dispensing device only meets the simple needs of users and is far from the standard of high-tech products for intelligent dispensing. The existing additive dispensing device generally has multiple accommodating parts, each of which is provided with a liquid storage box, so that liquid storage boxes storing different types of additives can be installed on an additive dispensing device at the same time, thereby achieving the effect of the dispensing device dispensing different types of additives one by one or in combination.

[0003] However, with the existing external additive delivery device, users are prone to misplacing the liquid storage box when replacing it. In particular, as the functions of washing machines increase, washing machines can automatically deliver detergents, stain removers, color protectants, and softeners. Each liquid storage box is distinguished by an identifier, and users need to learn the corresponding identifiers by themselves, which can easily lead to misremembering or misdelivery.

[0004] The invention patent with application number 201810617547.4 discloses a control method and device for automatically dispensing multiple clothing treatment agents into a washing machine. The automatic dispensing device includes a fixed-type treatment agent box for holding fixed-type clothing treatment agents and a variable-type treatment agent box for selectively holding one type / multiple types of clothing treatment agents at the same time; the control method includes: the washing machine executes a washing program, and the automatic dispensing device executes a corresponding dispensing process according to the selected clothing treatment agents in the fixed-type treatment agent box and / or the variable-type treatment agent box.

[0005] Although the automatic dispensing device disclosed in the above application can achieve the purpose of intelligent dispensing for different clothes by setting a selectable variable type treatment agent box and controlling the dispensing of the clothes treatment agent in the variable type treatment agent box, the dispensing device disclosed in the application cannot identify whether the type of additive stored in the variable type treatment agent box is correct, and it assumes that the correct type of liquid storage box is placed, so that in the subsequent washing process, it is impossible to accurately dispense according to the actual type of additive.

[0006] In view of this, the present invention is proposed. Summary of the invention

By using an identification conductive component set on the liquid storage box and a corresponding identification conductive component set on the additive dispensing device, information on the capacitance formed between the two corresponding conductive components can be obtained, thereby accurately detecting the type of additive stored in the liquid storage box. In the subsequent use process, the correct type of additive after identification can be accurately dispensed as needed, effectively solving the problem that the existing additive dispensing device cannot automatically detect and identify whether the type of additive stored in the liquid storage box is correct.

[0055] The present invention will be further described in detail below with reference to the embodiments.

[0056] like Figures 1 to 7 As shown, the present invention provides a liquid storage box 1, an additive dispensing device and a method for identifying the type of additive. The liquid storage box 1 provided by the present invention is provided with an identification conductive component 2, and any one or any combination of the number, position, shape, and resistivity of the identification conductive component 2 provided on the liquid storage box 1 corresponds to the type of additive stored in the liquid storage box 1.

[0057] In the present invention, there are a variety of liquid storage boxes 1 for containing different types of additives, and the number, position, shape, resistivity or any combination of the identification conductive components 2 provided on the different types of liquid storage boxes 1 is different, so that the information of the identification conductive components 2 provided on the liquid storage box 1 can be used to refer to the information of the type of additives stored in the liquid storage box 1.

[0058] In the embodiment of the present invention, the types of additives include the following: detergents, fragrance enhancers, softeners, disinfectants, etc., so that different types of additives can be put in separately or in combination, so that when the clothing processing device executes different types of programs, different types of additives are used to treat the clothes accordingly. At the same time, in the embodiment of the present invention, each liquid storage box 1 installed on the additive delivery device can also store detergents of different concentrations, such as: super concentrated, concentrated, ordinary, low foam, etc., so that when the clothing processing device executes different washing programs, the corresponding types of detergents can be put in to achieve the corresponding washing of different clothes, thereby achieving the purpose of improving the washing effect of the clothing processing device.

[0059] The present invention also provides an additive dispensing device, which has at least one accommodating portion 3 for installing the above-mentioned liquid storage box 1, and a plurality of identification conductive components 4 are arranged in the accommodating portion 3, each identification conductive component 4 covers the projection interval position of the identification conductive components 2 arranged on different liquid storage boxes 1 on the accommodating portion 3, and each identification conductive component 2 arranged on the liquid storage box 1 is spaced and corresponds to an identification conductive component 4 arranged in the accommodating portion 3, so as to form a capacitor corresponding to the type of additive stored in the liquid storage box 1.

[0060] In the present invention, the additive dispensing device extracts the information of the capacitance formed between the identification conductive component 2 on the liquid storage box 1 inserted in the accommodating portion 3 and the corresponding identification conductive component 4, so as to obtain the information of the type of additive stored in the liquid storage box 1 indicated by the information of the identification conductive component 2, thereby achieving the effect of accurately identifying the type of additive stored in the liquid storage box 1.

[0061] The present invention uses the identification conductive component 2 provided on the liquid storage box 1 and the corresponding identification conductive component 4 provided on the additive delivery device. When it is determined that the liquid storage box 1 is inserted into the receiving portion 3 of the additive delivery device, a capacitor is formed between the identification conductive component 2 and the identification conductive component 4 provided at the corresponding projection interval position on the liquid storage box 1. Based on the detection information of whether the identification conductive component 4 forms a capacitor and the capacitance of the formed capacitor, the type of additive in the liquid storage box 1 is inferred. The present invention can realize automatic identification of the type of additive stored in the liquid storage box 1 without contact through electrical detection, and has high identification efficiency and identification accuracy.

[0062] Embodiment 1

[0063] like Figure 1 , Figures 3 to 6 As shown, this embodiment provides a liquid storage box 1, wherein the liquid storage box 1 has a closed chamber for storing additives, and at least one identification conductive component 2 is provided on the liquid storage box 1, and any one or any combination of identification information such as the number, position, shape, resistivity, etc. of the identification conductive components 2 provided on the liquid storage box 1 corresponds to the type of additive stored in the liquid storage box 1. In this embodiment, the type of additive stored in the liquid storage box 1 is identified by using any one or any combination of identification information such as the number, position, and transmittance of the photosensitive component through the identification conductive component 2 provided on the liquid storage box 1, and the type of additive in the liquid storage box 1 is accurately identified through electrical identification detection. The structure is simple, easy to implement, and has high identification efficiency and recognition accuracy.

[0064] like Figure 1 , Figures 3 to 6 As shown, in this embodiment, the identification conductive component 2 is an identification conductive metal sheet arranged on the liquid storage box 1. The number, and / or position, and / or shape, and / or thickness, and / or material and other information of the identification conductive metal sheets arranged on the liquid storage box 1 for storing different types of additives are different, so that the capacitance of the capacitor formed between the identification conductive metal sheets arranged on the liquid storage box 1 for storing different types of additives and the identification conductive metal sheets arranged at the corresponding projection interval positions of the dispensing device is different. The capacitance of the capacitor formed by the identification conductive metal sheets arranged at different positions can be directly obtained by electrical detection, so the type of additive stored in the liquid storage box 1 can be directly and accurately obtained.

[0065] For example, Figure 5 As shown, the type of additive stored in the liquid storage box 1 can be identified by the thickness of the identification conductive metal sheet. In one solution, the identification conductive metal sheet can be set inside the box body of the liquid storage box 1. The box wall of the liquid storage box 1 has a set identification area. The identification conductive metal sheet can be set in the set identification area of ​​the liquid storage box 1. The identification conductive metal sheets set on different types of liquid storage boxes 1 are set to different thicknesses. The capacitance formed between the identification conductive metal sheet and the identification conductive metal sheet is detected by an electrical detection device, so that the type of additive stored in the liquid storage box 1 can be accurately obtained.

[0066] Also, if Figure 4As shown, the type of additive stored in the liquid storage box 1 is identified by the relative position of the identification conductive metal sheet set on the wall of the liquid storage box 1. In another scheme, the wall of the liquid storage box 1 has a set identification area, and the identification conductive metal sheet can be set in the set identification area of ​​the liquid storage box 1. The identification conductive metal sheets set on different types of liquid storage boxes 1 are set in different sections of the wall of the liquid storage box 1. By identifying the capacitance of the identification conductive metal sheet at the interval placement position corresponding to the identification area, the relative distance between the identification conductive metal sheet and the identification conductive metal sheet can be obtained, and then the type of additive stored in the liquid storage box 1 can be accurately obtained. For example: the identification conductive metal sheet can be exposed and set on the outer wall of the liquid storage box 1; or, the identification conductive metal sheet can be buried inside the box wall of the closed chamber constituting the liquid storage box 1; or, the identification conductive metal sheet can be set on the inner wall of the box wall constituting the closed chamber of the liquid storage box 1, etc.

[0067] Preferably, if Figure 1 and Figure 6 As shown, in this embodiment, the positions and quantities of the marking conductive metal sheets provided on the liquid storage box 1 correspond to the types of additives stored in the liquid storage box 1. Further preferably, the marking conductive metal sheets provided on the liquid storage box 1 have a variety of permutations and combinations, and the marking conductive metal sheets in different permutations and combinations correspond to different types of additives stored in the liquid storage box 1.

[0068] In one embodiment, the liquid storage box 1 has a plurality of set identification areas on its wall, and a corresponding identification conductive metal sheet is provided on the wall of the liquid storage box 1 in any identification area or in different arrangement and combination positions. By identifying the capacitance of the identification conductive metal sheets at the corresponding interval positions of all identification areas, the position and quantity of the identification conductive metal sheets can be obtained, and then the type of additive stored in the liquid storage box 1 can be accurately obtained.

[0069] Preferably, Figure 1 , Figures 3 to 5 As shown, the liquid storage box 1 has an insertion end 11 corresponding to the injection device, and the insertion end 11 of the liquid storage box 1 is arranged with at least one protrusion 6 protruding along the insertion direction of the liquid storage box 1, and one or more of the protrusions 6 are provided with a marking conductive metal sheet, which can be exposed at the end of the protrusion 6 and / or buried inside the protrusion 6. By arranging the marking conductive metal sheet on the protrusion 6, the protrusion 6 can not only play the role of marking the type of additive stored in the liquid storage box 1, but also play the role of inserting and positioning between the liquid storage box 1 and the injection device.

[0070] The insertion end 11 of the liquid storage box 1 has a plurality of set positions arranged in a plurality of rows and columns, and an identification conductive metal sheet is provided at one or a combination of each set position; at the same time, in order to ensure the identifiability of the capacitance formed between the identification conductive metal sheet provided at the protrusion 6 of the insertion end 11 and the identification conductive metal sheet, it is generally necessary to place the identification conductive metal sheet perpendicular to the insertion direction of the liquid storage box 1.

[0071] like Figure 6 As shown, in this embodiment, in order to realize the formation of capacitance between the identification conductive component 2 and the identification conductive component 4, it is necessary to electrically connect the identification conductive component 2 and the identification conductive component 4, and set a pressure unit 5 on the electrical connection path, so as to realize the use effect of accurately detecting the capacitance of the capacitor formed by the identification conductive component 2 and the identification conductive component 4 forming a capacitor plate. In order to achieve the above effect, the following settings are made in this embodiment:

When the liquid storage box 1 is installed in the receiving portion 3, a capacitance indicating the type of additive stored in the liquid storage box 1 can be formed between the electrical metal sheet on the liquid storage box 1 and the identification conductive metal sheet provided at the corresponding position in the receiving portion 3 of the delivery device. The type of additive stored in the liquid storage box 1 can be inferred based on the detected capacitance information. The above structure is not only simple in structure and easy to implement, but also can realize accurate identification of the type of additive contained in the liquid storage box 1 by providing different arrangements and combinations of marking conductive metal sheets of different numbers, positions, thicknesses and shapes on the liquid storage box 1, thereby realizing significant technical progress in automatic and accurate identification of the type of additive.

[0076] In this embodiment, the additive dispensing device can adopt any of the existing structures to dispense additives into the liquid storage box 1 placed in the accommodating portion 3; for example: the additive dispensing device is provided with at least one liquid storage box 1 for storing additives, and each liquid storage box 1 is connected to the water path of the washing machine to supply water into the barrel through a dispensing unit, so as to achieve the purpose of each additive dispensing device controlling at least one additive to be dispensed into the barrel accordingly.

[0079] Preferably, in order to ensure that a capacitor can be formed between the identification conductive metal sheet and the corresponding identification conductive metal sheet, it is necessary to separate the two with a non-conductive material, and the following arrangement can be performed: there is a separation space between the identification conductive metal sheet and the corresponding identification conductive metal sheet, and the separation space has a box wall of the liquid storage box 1 and / or a cavity wall of the accommodating portion 3 made of non-conductive material, so that the box wall of the liquid storage box 1 and / or the cavity wall of the accommodating portion 3 are utilized to separate the two capacitor plates formed by the identification conductive metal sheet and the corresponding identification conductive metal sheet with a non-conductive material, thereby ensuring that the capacitance of the formed capacitor changes accordingly, thereby achieving the effect of accurately identifying different types of liquid storage boxes 1.

[0080] In this embodiment, the projection area of ​​the marking conductive metal sheet provided on the liquid storage box 1 on the surface and / or inside of the accommodating portion 3 along the direction perpendicular to itself is the projection interval position of the marking conductive component 2 provided on the liquid storage box 1 on the accommodating portion 3; for example: when the marking conductive metal sheet is provided at the insertion end 11 of the liquid storage box 1, the projection area of ​​the marking conductive metal sheet on the surface and inside of the bottom wall of the accommodating groove along the insertion direction of the liquid storage box 1 is the projection interval position of the marking conductive component 2 provided on the liquid storage box 1 on the accommodating portion 3; or, when the marking conductive metal sheet is provided on the side wall of the liquid storage box 1 and is parallel to the insertion direction, the projection area of ​​the marking conductive metal sheet on the surface and inside of the side wall of the accommodating groove along the vertical direction of insertion of the liquid storage box 1 is the projection interval position of the marking conductive component 2 provided on the liquid storage box 1 on the accommodating portion 3.

[0081] Preferably, Figure 2 As shown, the accommodating portion 3 has a groove bottom wall corresponding to the insertion end 11 of the liquid storage box 1, and the groove bottom wall is provided with a corresponding plug-in groove 7 covering the protrusions 6 of the insertion ends 11 of different liquid storage boxes 1, and the bottom of each groove 7 is respectively and one by one provided with an identification conductive metal sheet perpendicular to the insertion direction of the liquid storage box 1. The identification conductive metal sheet provided at the bottom of each groove 7 is used for one-to-one identification and detection of the identification conductive metal sheet provided on the protrusion 6 of the insertion end 11 of the liquid storage box 1, so that the different types of additives stored in the liquid storage box 1 can be accurately obtained.

[0082] Furthermore, if Figures 1 to 6 As shown, the plurality of protrusions 6 extend along the insertion direction of the insertion end 11 of the liquid storage box 1 and are arranged and distributed in multiple rows and columns on the end surface of the insertion end 11; a plurality of grooves 7 are also arranged on the bottom wall of the groove of the accommodating portion 3 of the delivery device; the positions of the protrusions 6 on different liquid storage boxes 1 and the grooves 7 provided on the bottom wall of the groove of the accommodating portion 3 of the delivery device correspond one by one along the insertion direction of the liquid storage box 1.

[0083] Furthermore, the arrangement and combination of the protrusions 6 on the liquid storage boxes 1 for storing different types of additives are different, and an identification conductive component 2 is correspondingly set in each protrusion 6; after the liquid storage box 1 is installed in the accommodating portion 3, a capacitor is formed between the identification conductive component 2 set in the corresponding protrusion 6 and the identification conductive component 4 set at the corresponding interval projection position in the accommodating portion 3, and different types of liquid storage boxes 1 can be identified based on the detection information of whether each identification conductive component 2 in the accommodating portion 3 forms a capacitor.
