Description

Technical Field

[0001] This application relates to a washing device. Specifically, it relates to the technical field of the feed hopper in the washing device. Background Technology

[0002] To store detergent, washing equipment has a detergent dispenser. The dispenser may have multiple storage compartments for the detergent. Some storage compartments, especially those used for automatic dispensing, are designed to be sealed to prevent moisture evaporation or spoilage of the detergent. However, air trapping can occur when filling such compartments with detergent, preventing the detergent from flowing into the compartments quickly. Utility Model Content

[0003] The purpose of this application is to provide a washing device, in particular enabling the linkage between the opening and closing of the feed box or feed cover and the opening and closing of the vent, thereby solving the problem of trapped air when filling detergent and maintaining closed storage when not filling detergent.

[0004] According to a first aspect of this application, an embodiment of this application provides a washing apparatus, characterized in that the washing apparatus comprises: The main body has a washing chamber for placing items to be washed; A detergent dispenser that can be selectively pushed into or pulled out of the main body, the detergent dispenser having at least one storage cavity for closed storage of detergent, the storage cavity having a feeding port for injecting the detergent and a vent for communicating the interior of the storage cavity with the outside atmosphere, the detergent dispenser having a feeding cap for opening and closing the feeding port; The washing device includes a first switching mechanism for an exhaust port, the first switching mechanism closing the exhaust port in response to the push-in state of the feed box and opening the exhaust port in response to the pull-out state of the feed box; or, the washing device includes a second switching mechanism for an exhaust port, the second switching mechanism closing the exhaust port in response to the closed state of the feed cover and opening the exhaust port in response to the open state of the feed cover.

[0005] Thus, especially through the switching mechanism, the problem of trapped air is avoided by opening the vent when filling the storage chamber with detergent, and a closed storage is achieved by closing the vent when not filling with detergent.

[0006] According to an optional embodiment of this application, the first switching mechanism includes a closure portion fixedly disposed in the main body. In the pushed-in state of the material box, the vent is closed by the closure portion; in the pulled-out state of the material box, the vent disengages from the closure portion. Thus, the first switching mechanism is structurally simple.

[0007] According to an optional embodiment of this application, the vent is located on the top wall of the storage cavity, and the sealing portion is located on the top cover of the material box of the main body. This effectively prevents detergent from flowing out of the vent.

[0008] According to an alternative embodiment of this application, the front side of the closure has a guide ramp. This prevents interference or jamming between the vent area and the closure when the cassette is pushed in and pulled out.

[0009] According to an alternative embodiment of this application, the closure is formed by a partially downwardly protruding recessed structure of the cartridge top cover. This allows the closure to be easily integrated into the cartridge top cover while the cartridge can still be easily pushed in and pulled out.

[0010] According to an optional embodiment of this application, the first switching mechanism includes a closing portion movably disposed in the storage cavity and an opening device disposed in the main body. Based on the extraction movement of the cassette, the opening device causes the closing portion to open, thereby opening the vent. When the cassette is pushed in, the closing portion disengages from the opening device and closes the vent. This achieves the linkage between the opening and closing of the cassette and the opening and closing of the vent in another way.

[0011] According to an optional embodiment of this application, the opening device includes a pusher for actuating the closure portion or a magnet for moving the closure portion by magnetic force. This allows for a simple implementation of the opening device.

[0012] According to an optional embodiment of this application, the second switching mechanism includes a closing portion fixedly disposed on the feeding cover, the vent being adjacent to the feeding port, and, in the closed state of the feeding cover, the closing portion closes the vent, while in the open state of the feeding cover, the closing portion moves away from the vent, allowing the vent to open. This allows for the linkage between the opening and closing of the feeding cover and the opening and closing of the vent with a simple structure.

[0013] According to an optional embodiment of this application, the second switching mechanism includes a closing portion disposed relatively movably in the storage cavity and a coupling mechanism that movably couples the closing portion to the feeding cover. The opening movement of the feeding cover is transmitted to the closing portion via the coupling mechanism, causing the closing portion to open the vent hole. The closing movement of the feeding cover causes the closing portion to close the vent hole. This provides another way to implement the second switching mechanism.

[0014] According to an alternative embodiment of this application, the coupling mechanism is integrated into the feeding cover or a connecting rod or cable connected to the feeding cover. This allows for a simple structural implementation of the second switching mechanism.

[0015] According to an optional embodiment of this application, the first switching mechanism and / or the second switching mechanism includes a closure portion and an actuator. The actuator is used to drive the closure portion to open and close the vent. The washing device includes a sensor and a controller. The sensor includes a first sensor for detecting the position of the feed hopper and / or a second sensor for detecting the orientation of the feed cover. The controller is used to control the actuator based on the detection of the sensors. This allows the first switching mechanism and / or the second switching mechanism to be implemented in another manner.

[0016] According to an optional embodiment of this application, the closure and the actuator are disposed in the storage cavity.

[0017] According to an optional embodiment of this application, the washing device is a washing machine or a washer-dryer.

[0018] According to an optional embodiment of this application, the detergent is a fabric softener, disinfectant, or laundry liquid.

[0019] According to an optional embodiment of this application, the vent hole is a circular hole, a square hole, or an irregularly shaped hole.

[0020] According to an optional embodiment of this application, the main body is provided with a limiting structure for limiting the extraction of the material box. This prevents the material box from falling out when fully extracted.

[0021] According to an optional embodiment of this application, in the pushed-in state, the feed box is flush with the main body. This makes the washing equipment more aesthetically pleasing.

[0022] According to an optional embodiment of this application, the storage cavity is a storage cavity for automatic feeding.

[0023] According to an optional embodiment of this application, the vent is located in the rear section of the main body of the storage cavity when the material box is withdrawn. Attached Figure Description

[0026] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.

[0027] Figure 1 A schematic diagram shows a front view of a washing device. This washing device can be a washing machine or a washer-dryer, but it can also be other types of washing devices.

[0028] like Figure 1 As shown, the washing equipment includes: Main body 1, the main body 1 having a washing chamber 10 for placing the items to be washed; A material box 2 that can be selectively pushed into or pulled out of the main body 1.

[0029] The detergent may be fabric softener, disinfectant, or laundry liquid, or other types of detergent.

[0030] The detergent container 2 has at least one storage cavity 20 for closed storage of detergent (see [link]). Figure 3 The storage chamber 20 is particularly suitable for automatic dispensing. In such a storage chamber 20, after a single injection of detergent, only a portion of the detergent is automatically drawn from the storage chamber 20 each time, depending on demand. Therefore, the storage chamber 20 stores detergent for an extended period. Consequently, the storage chamber 20 should ideally be a closed system to prevent moisture evaporation and detergent deterioration.

[0031] Figure 2 An example of material box 2 is shown schematically in a 3D view. See also Figure 2 The detergent box 2 has at least one storage cavity 20 for closed storage of detergent, the storage cavity 20 has a feeding port 21 for injecting the detergent, and the detergent box 2 has a feeding cover 23 for opening and closing the feeding port 21.

[0032] This application proposes that the storage cavity 20 has an exhaust port 22 for communicating the interior of the storage cavity 20 with the outside atmosphere, and the washing device includes a first switching mechanism 3 for the exhaust port 22, the first switching mechanism 3 closing the exhaust port 22 in response to the push-in state of the material box 2 and opening the exhaust port 22 in response to the pull-out state of the material box 2.

[0033] Figure 3 A first example of the first switching mechanism 3 is schematically shown in a cross-sectional view with the material box 2 in the pushed-in state.

[0034] Figure 4 Enlarged to show Figure 3 The area of ​​the vent 22 of the material box 2.

[0035] Figure 5 Schematic illustration Figure 3 The material box 2 is in the withdrawn state.

[0036] The first switching mechanism 3 specifically achieves the linkage between the opening and closing of the material box 2 and the opening and closing of the vent 22. Therefore, when the material box 2 is pulled out, see... Figure 5 The storage chamber 20 is connected to the outside atmosphere via the open vent 22. In this case, injecting detergent into the storage chamber 20 will not create trapped air. When the detergent box 2 is pushed in, see [further details omitted]. Figure 3 The vent 22 is then sealed, thus achieving closed storage of detergent in the storage chamber 20.

[0037] The exhaust port 22 can be a circular port, a square port, or an irregularly shaped port.

[0038] like Figure 3As shown, exemplarily, in the pushed-in state, the material box 2 is flush with the body 1.

[0039] According to an exemplary embodiment, the main body 1 is provided with a limiting structure for limiting the extraction of the material box 2. Therefore, the material box 2 will not fall off when it is completely detached from the main body 1.

[0040] According to an exemplary embodiment, such as Figure 5 As shown, the storage cavity 20 has a rear section 202 that remains in the main body 1 when the material box 2 is withdrawn, and a front section 201 extending from the main body 1. The vent 22 is located in the rear section 202. This allows the vent 22 to be concealed at all times, resulting in an aesthetically pleasing appearance. However, it is also conceivable that the vent 22 is located in the front section 201.

[0041] According to an exemplary embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the first switching mechanism 3 includes a sealing portion 5 fixedly disposed in the main body 1. When the material box 2 is pushed in, the vent 22 is closed by the sealing portion 5. When the material box 2 is pulled out, the vent 22 disengages from the sealing portion 5. Thus, the first switching mechanism 3 can be implemented with a particularly simple structure.

[0042] Here we can imagine, see Figure 4 The vent 22 is located on the top wall 203 of the storage cavity 20, and the sealing part 5 is located on the top cover 11 of the material box of the main body 1. This prevents detergent from escaping from the vent 22.

[0043] Instead of the top wall 203, it is also conceivable that the vent 22 is located on the side wall of the storage cavity 20.

[0044] According to an exemplary embodiment, such as Figure 4 As shown, the front side of the closure 5 has a guide ramp 13. This prevents the material box 2 from interfering with or getting stuck in the vent 22 area when it is pushed in and pulled out.

[0045] According to an exemplary embodiment, such as Figure 4 As shown, the closure 5 is formed by a partially downward protruding recessed structure 12 of the top cover 11 of the material box. That is, the closure 5 can be integrated into the top cover 11 of the material box.

[0046] Alternatively, the closure 5 can be a separate component that can be installed onto the top cover 11 of the material box.

[0047] Figure 6 A second example of the first switching mechanism 3 is shown schematically.

[0048] Here, with Figures 3 to 5 Similarly, the exhaust port 22 is located in the rear section 202.

[0049] The difference is that the first switching mechanism 3 includes a closing part 5 that is movably disposed in the storage cavity 20 and an opening device 30 disposed in the main body 1. Based on the pulling movement of the material box 2, or as the material box 2 is pulled out, the opening device 30 causes the closing part 5 to perform an opening movement to open the vent 22. When the material box 2 is pushed in, the closing part 5 disengages from the opening device 30 and closes the vent 22.

[0050] exist Figure 6 In this design, the opening device 30 is exemplarily a pusher 31, such as a push rod. The closing part 5 is, for example, a pivotable flip cover. When the closing part 5 disengages from the opening device 30, it pivots under its own weight to a position that closes the vent 22. Figure 6 In the middle, the exhaust port 22 is constructed on a vertically extending surface. Alternatively, it can be designed as follows: Figure 6 For reference, the exhaust port 22 is constructed on a surface that extends obliquely to the lower right in a downward direction, thereby making better use of the gravity of the sealing part 5 to seal the exhaust port 22.

[0051] Figure 7 A third example of the first switching mechanism 3 is illustrated schematically.

[0052] and Figure 6 The difference in the second example is particularly that the opening device 30 includes a magnet 32 ​​for moving the closing part 5 by magnetic force. The closing part 5 is, for example, a movable lid that can move up and down and is attracted by the magnet 32. When the cassette 2 is pulled out, the closing part 5 of the cassette 2 moves under the magnet 32 ​​of the opening device 30 and is attracted to open, while when the cassette 2 is pushed in, the closing part 5 of the cassette 2 falls due to gravity as it moves away from the magnet 32 ​​and covers the vent 22. Additionally, to enhance the sealing effect on the vent 22, a spring may be provided for loading the closing part 5 toward the vent 22.

[0053] Figure 8 The illustration shows a first example of the second switching mechanism 4 of the washing device.

[0054] like Figure 8 As shown, the washing device includes a second switching mechanism 4 for the vent 22, which closes the vent 22 in response to the closed state of the feeding cover 23 and opens the vent 22 in response to the open state of the feeding cover 23.

[0055] This achieves the linkage between the opening and closing of the feeding cover 23 and the opening and closing of the vent 22. Thus, when the feeding cover 23 is opened, the opening of the vent 22 avoids the problem of air trapping during detergent injection, while when the feeding cover 23 is closed, the detergent is stored in a closed manner in the storage chamber 20.

[0056] According to an exemplary embodiment, such as Figure 8 As shown, the second switching mechanism 4 includes a closing part 5 fixedly disposed on the feeding cover 23. The vent 22 is adjacent to the feeding port 21. When the feeding cover 23 is closed, the closing part 5 closes the vent 22. When the feeding cover 23 is open, the closing part 5 moves away from the vent 22, thus opening the vent 22.

[0057] Thus, the second switching mechanism 4 was realized with an extremely simple structure.

[0058] Figure 9 A second example of the second switching mechanism 4 of the washing device is schematically shown.

[0059] According to an exemplary embodiment, such as Figure 9 As shown, the second switching mechanism 4 includes a closing part 5 that is movably disposed in the storage cavity 20 and a coupling mechanism 40 that movably couples the closing part 5 with the feeding cover 23. The opening movement of the feeding cover 23 is transmitted to the closing part 5 via the coupling mechanism 40, causing the closing part 5 to open the exhaust hole 22. The closing movement of the feeding cover 23 causes the closing part 5 to close the exhaust hole 22.

[0060] exist Figure 9 In this example, the coupling mechanism 40 is integrated into the feeding cover 23. Alternatively, it is conceivable that the coupling mechanism 40 is a link or cable connected to the feeding cover 23. Furthermore, in Figure 9 The image also shows a spring 7, which, when the feed cover 23 is closed, seals the vent 22 based on the spring 7.

[0061] Figures 3 to 9 The diagram shows the linkage between the opening and closing of the material box 2 or the feeding cover 23 and the opening and closing of the vent 22, which is implemented using a purely mechanical structure.

[0062] Figure 10 An alternative implementation of the first switching mechanism 3 or the second switching mechanism 4 is illustrated schematically.

[0063] According to an exemplary embodiment, such as Figure 10As shown, the first switching mechanism 3 and / or the second switching mechanism 4 include a closure 5 and an actuator 60. The actuator 60 is used to drive the closure 5 to open and close the vent 22. The washing device includes a sensor 61 and a controller 62. The sensor 61 includes a first sensor for detecting the position of the feed hopper 2 and / or a second sensor for detecting the orientation of the feed cover 23. The controller 62 is used to control the actuator 60 based on the detection of the sensor 61. The actuator 60 is particularly electric, hydraulic, or pneumatic. Furthermore, the closure 5 and the actuator 60 can be directly disposed in the storage cavity 20.
