Description

Technical Field

[0001] The present invention belongs to the field of clothing treatment, and specifically relates to a clothing treatment device. Background Art

[0002] In the existing clothing treatment devices, especially the clothes dryers, there is usually a device for removing lint in the air duct inside the device. Without such a device, the lint will directly adhere to the condenser along with the air flow, which affects the condenser's condensation effect, and the lint adhering to the condenser is also not easy to collect, bringing inconvenience to the user. Therefore, the setting of the lint filter device is very necessary. However, the working environment of the lint filter is very harsh. The long-term air flow impact often makes it difficult for it to maintain the best filtering position. Moreover, after being used for a period of time, due to the increasing amount of lint accumulated on it, the air flow environment it faces becomes more complex, and the accumulated lint will also affect the subsequent filtering process, making the lint accumulation situation very complex, and further affecting the fluidity of the air flow passing through the accumulated lint layer. The impact of the complex and changeable air flow on the lint filter device further increases the adverse effect on the installation stability of the lint filter. The vibration generated by the lint filter will inevitably generate noise, affecting the user experience. Further, the lint filter in the existing technology is generally not directly installed on the clothing treatment device, but is installed through an installation hopper. The installation hopper can change the extension direction of the lint filter device through the snap-fit of the rotating shaft, enabling the user to take it out. However, the installation hopper itself is a movable part, and there are gaps in its own installation and use during flipping. If the lint filter vibrates or even falls off, the installation hopper will also vibrate and generate noise. In most cases, it is impossible to perform the operation of removing the lint filter device during the operation of the device, and it is not suitable to remove the lint filter device during the operation of the device. Therefore, how to timely detect the abnormality of the lint filter device during the operation of the device and perform a cleaning operation according to factors such as the degree of the abnormality has become an urgent problem to be solved. Moreover, the vibration and position change generated during the use of the lint filter device can, to a certain extent, characterize the lint filtering situation and the lint accumulation on the lint filter. Collecting and processing the data on the use situation of the lint filter can be used to characterize other aspects of the clothing treatment situation, which brings a deeper challenge to the performance of the clothing treatment device.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a structure installation principle, installation method of a lint filtering device and a design of a control system cooperating therewith, so that a laundry treatment device can judge the cleaning timing according to the position change of the lint filtering device, ensure the use effect of the lint filtering device, and collect and utilize the data generated by the lint filtering device.

[0005] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is:

[0006] A laundry treatment device, comprising a lint filtering device, a position detection device for detecting the position state of the lint filtering device during the operation of the laundry treatment device, and a cleaning device for cleaning the lint filtering device; the cleaning device determines the timing to start the cleaning operation according to the detection result of the position detection device.

[0007] The present invention is further arranged as: the cleaning device determines the timing to adjust the cleaning method and / or end the cleaning operation according to the detection result of the position detection device.

[0008] The present invention is further arranged as: the cleaning device cleans the lint filtering device by spraying a cleaning medium onto the lint filtering device.

[0009] The present invention is further arranged as: the position detection device detects the relative position state between the lint filtering device and the laundry treatment device, and generates a corresponding signal; the control system adjusts the operation of the cleaning device according to the signal;

[0010] Preferably, the position detection device includes a detection connection member, a detection point, and a controller that cooperate with each other; the detection connection member obtains the relative position relationship between the lint filtering device and the laundry treatment device, and mainly controls the connection relationship between the detection point and the controller based on this to generate a corresponding signal, thereby realizing the detection of the position state of the lint filtering device;

[0011] Further preferably, the relative positions of the detection point and the controller are fixed, and the detection connection member controls the on-off of the connection between the two;

[0012] Even more preferably, the number of the detection points is at least two, different detection points correspond to different detection values, and different detection signals are generated when different detection points are connected to the controller; the detection connection member connects the corresponding detection points to the controller according to the relative position relationship between the lint filtering device and the laundry treatment device;

[0013] Even more preferably, the detection connection member is connected to the lint filtering device.

[0014] The present invention is further configured such that: the position detection device includes a position reset member for restoring the detection connection member, thereby disconnecting between the detection point and the controller and generating a corresponding signal, so that the cleaning device adjusts the cleaning mode / ends the cleaning operation;

[0015] Preferably, the cleaning mode includes the selection of cleaning angle and / or cleaning intensity and / or cleaning medium;

[0016] Preferably, the restored position includes restoring to the initial position.

[0017] The present invention is further configured such that: the cleaning medium includes gas and / or liquid;

[0018] Preferably, the cleaning device includes a first cleaning unit and a second cleaning unit, the cleaning medium of the first cleaning unit is liquid, and the cleaning medium of the second cleaning unit is gas.

[0019] The present invention is further configured such that: the lint filtering device is disposed on the clothing treatment device through the mounting portion;

[0020] Further preferably, the number of the mounting portions is at least two;

[0021] Even more preferably, different mounting portions are respectively disposed at different positions.

[0022] The present invention is further configured such that: the position detection device mainly detects the position state of the lint filtering device by detecting the position change of the mounting portion;

[0023] Preferably, the position detection device is connected to the mounting portion;

[0024] Further preferably, the detection connection member is connected to the mounting portion.

[0025] The present invention is further configured such that: the number of the cleaning devices is at least two, and the positions of each cleaning device relative to the lint filtering device are different;

[0026] Preferably, at least one of the cleaning devices is disposed above the lint filtering device;

[0027] Furthermore, at least two of the cleaning devices determine the timing and / or mode of starting and / or adjusting and / or ending the cleaning operation according to the detection result of the position detection device differently, so that at least two of the cleaning devices perform the cleaning operations asynchronously;

[0028] Preferably, the control system of the device obtains the cleanliness of the lint filtering device according to the detection result of the position detection device and / or the working state of the cleaning device;

[0029] Preferably, the control system displays the cleanliness of the lint filtering device to the user after the laundry processing apparatus completes the laundry processing operation.

[0030] The present invention is further configured as follows: the laundry processing device comprises a humidity detection device for detecting the humidity of the air intake of the device; preferably, when the humidity detection device detects that the air intake humidity exceeds a corresponding threshold, the control system lowers the threshold for determining the timing of starting the cleaning device;

[0031] Preferably, when the humidity detection device detects that the intake air humidity exceeds a corresponding threshold, the control system increases the threshold for determining when the cleaning device should stop;

[0032] Through the above design, the cleaning device is more sensitive to the lint filter. When there is a hidden danger of lint accumulation in the lint filter, it is cleaned to prevent the lint with high humidity brought by humid air from adhering to the lint filter for a long time and being difficult to remove. This design prolongs the cleaning time of the lint filter on the one hand, and increases the cleaning frequency of the lint filter on the other hand, which is conducive to timely removal of lint attached to the lint filter under high humidity conditions.

[0033] The present invention is further configured such that: when the humidity detection device detects that the intake air humidity exceeds a corresponding threshold value, after each cleaning device completes the cleaning operation on the lint filtering device, gas is sprayed on the lint filtering device and maintained for a certain period of time.

[0034] Through the above design, the cleaning device dries the lint filter device after cleaning the lint attached to the lint filter device, so that the lint attached thereto will not be difficult to clean due to the increase in air humidity.

[0035] The present invention is further configured as follows: the clothing processing device includes a washing machine / dryer / washer-dryer.

[0036] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0037] 1. The clothes processing device introduced in the present invention adds a position detection device to the device structure, which detects the position state of the lint filter device during the operation of the device, ensures that the control system can always obtain the position information of the lint filter, and provides data support for other applications;

[0038] 2. With the laundry treatment device introduced in the present invention, the position state of the lint filtering device is monitored in real time during the operation of the device, and based on this, the timing for the cleaning device to start working is determined. Due to the different amounts and attachment conditions of lint adhering to the lint filtering device, its position will change accordingly. Alternatively, components for providing a certain margin for the position change of the lint filtering device can be preset in the structural design of the lint filtering device and / or the installation part, so that the lint filtering device can generate corresponding position changes according to the amount of lint adhering to it and the position where the lint is distributed, thereby characterizing the attachment situation of the lint. When the position state of the lint filtering device meets certain conditions, it can be determined that there is too much lint accumulated on it, and a cleaning operation should be performed. Further, the control system controls the cleaning device to start cleaning the lint filtering device. It can be seen that judging the amount of lint adhering to the lint filtering device and the attachment situation of the lint based on the position state of the lint filtering device can realize the judgment of the timing of the cleaning operation, making the working basis of the cleaning device the specific situation of the lint filtering device, rather than the abstract concept such as "continuous usage time" in the prior art, further ensuring the timeliness of cleaning the lint filtering device and avoiding frequent cleaning operations from affecting the use of the lint filtering device or increasing the control burden of the system;

[0039] 3. The cleaning device has a reasonable structure and a reasonable installation position, and sprays on the lint filtering device from above, which is beneficial to making full use of the cleaning medium sprayed out to better wash the lint filtering device;

[0040] 4. With the laundry treatment device introduced in the present invention, there are various choices for the spray medium, and multiple media can be used selectively or alternately. For example, an operation of spraying liquid can be performed on the lint filtering device at the initial stage when it starts working. When the degree of change in the position state of the lint filtering device is alleviated and the amount of change in the position state drops to a certain value, the cleaning device then adjusts the spray medium to gas, so that the cleaning of the lint filtering device is based on meeting the filtering function of the lint filtering device itself, avoiding the cleaning process from affecting the cleaning function of the lint filtering device;

[0041] 5. With the laundry treatment device introduced in the present invention, the cleaning device is connected to the lint filtering device, so that when the spraying device cleans the lint filtering device, the relative position relationship between the spraying device and the lint filtering device can be ensured, and the medium sprayed by the spraying device can be accurately sprayed onto the lint filtering device; further, when the lint filtering device generates a position change, it will drive the spraying device to generate a position change together, so that the positions of the two are synchronized, thereby ensuring the effectiveness of the spraying direction and spraying position; this technical solution can be achieved by setting the medium guiding component of the spraying device to a soft and elastic structure, for example, setting it as a rubber tube;

[0042] 6. Through the laundry treatment device introduced in the present invention, the cleanliness of the lint filter device is obtained based on the detection result of the position detection device and / or the working state of the cleaning device, and the cleanliness is fed back to the user, enabling the user to have an intuitive feeling of the cleaning situation of the lint filter device and ensuring that the user grasps the working conditions of the lint filter device and the cleaning device.

[0043] 7. Through the laundry treatment device introduced in the present invention, different cleaning devices are used to perform cleaning operations for different cleaning media. Preferably, the number of the first cleaning unit and / or the second cleaning unit is multiple, and they are arranged at intervals; then different cleaning devices are responsible for spraying different media, which can simplify the working mode of the control system. Moreover, by analogy, a third set of cleaning devices can be added for spraying special cleaning agents.

[0044] 8. Through the laundry treatment device introduced in the present invention, the adjustment of the connection strength between the lint filter device and the device can be realized. This technical solution has a wide range of applications and can be applied to laundry treatment devices such as washing machines, dryers, and washing-drying integrated machines. Since the impact of water flow on the lint filter device is relatively large during the laundry treatment process of a washing machine, it is easy for the lint filter device to loosen and fall off, partially losing its filtering function. The technical solution in the present invention completely solves this technical problem.

Detailed implementation manners

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0054] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0055] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] The laundry treatment device introduced in the present invention includes a lint filtering device, a position detection device for detecting the position state of the lint filtering device during the operation of the laundry treatment equipment, and a cleaning device for cleaning the lint filtering device; the cleaning device determines the timing to start performing the cleaning operation according to the detection result of the position detection device.

[0057] Through the laundry treatment equipment introduced in the present invention, a position detection device is added to the equipment composition, and the position state of the lint filtering device is detected during the operation of the equipment, ensuring that the control system can always obtain the position information of the lint filter and providing data support for other applications.

[0058] Further, through the laundry treatment device introduced in the present invention, the cleaning device determines the timing for adjusting and / or ending the cleaning operation according to the detection result of the position detection device. During the operation of the device, the position state of the lint filter device is monitored in real time, and based on this, the timing for the cleaning device to start working is judged. Due to the different amounts and attachment conditions of the lint attached to the lint filter device, its position will change accordingly. Alternatively, components for providing a certain margin for the position change of the lint filter device can be preset in the structural design of the lint filter device and / or the installation part, so that the lint filter device can generate corresponding position changes according to the amount of lint attached to it and the position where the lint is distributed, thereby characterizing the attachment situation of the lint. When the position state of the lint filter device meets certain conditions, it can be determined that too much lint has accumulated on it and the cleaning operation should be performed. Further, the control system controls the cleaning device to start cleaning the lint filter device. It can be seen that judging the amount of lint attached to the lint filter device and the attachment situation of the lint according to the position state of the lint filter device can realize the judgment of the timing of the cleaning operation, so that the working basis of the cleaning device is the specific situation of the lint filter device, rather than the abstract concept such as "continuous use time" in the prior art, further ensuring the timeliness of cleaning the lint filter device and avoiding the frequent cleaning operation from affecting the use of the lint filter device or increasing the control burden of the system.

[0059] Embodiment 1

[0060] As Figure 1 shown, for the laundry treatment device described in this embodiment, the cleaning device cleans the lint filter device by spraying a cleaning medium onto the lint filter device. The position detection device is used to detect the relative position state between the lint filter device and the laundry treatment device and generate a corresponding signal for adjusting the operation of the cleaning device;

[0061] The position detection device includes a detection connection member 41, a first detection point 42, and a controller 43 that cooperate with each other; the detection connection member 41 obtains the relative position relationship between the lint filter device and the laundry treatment device, and mainly based on this, controls the connection relationship between the first detection point 42 and the controller 43 to generate a corresponding signal, thereby realizing the detection of the position state of the lint filter device. The detection connection member is arranged between the first part of the installation part and the second part of the installation part, and can move in the direction of the second part of the installation part under the push of the first part of the installation part, thereby connecting the detection point and the controller. Figure 2 The structure shown in is the state where the detection connection member 41 connects the first detection point 42 and the controller 43. The detection connection member 41 is made of a material that allows current to pass through. When it moves to Figure 2When in the shown position, the circuit formed by the first detection point 42 and the controller 43 is connected, and then a signal is generated. When the first piece 31 of the installation part moves to the left to the position shown in FIG. 2, it indicates that the lint filtering device is away from the equipment, so that the detection connecting piece 41 also moves Figure 2 to the left, thereby disconnecting the circuit formed by the first detection point 42 and the controller 43, and then generating a signal.

[0062] Preferably, in this embodiment, the relative positions between the first detection point 42 and the controller 43 are fixed, and the connection relationship between the two is controlled by the detection connecting piece 41 to be switched on and off.

[0063] Embodiment Two

[0064] As Figure 2 shown, the difference between the laundry treatment device in this embodiment and the above embodiment is that: the number of the detection points is multiple, and the multiple detection points respectively correspond to different detection values. When different detection points are connected to the controller, different detection signals are generated; the detection connecting piece connects the corresponding detection points to the controller according to the relative position relationship between the lint filtering device and the laundry treatment equipment. Further, the detection connecting piece is connected to the lint filtering device. Then the detection points in this embodiment at least include a first detection point 42 and a second detection point 45. When the moving distance of the detection connecting piece is different, the connection conditions of the multiple detection points are different, and then different signals are generated to represent different position change amounts of the lint filtering device. During implementation, when the first detection point 42 is switched on, it indicates that the lint filtering device starts the filtering work. As the laundry treatment progresses, when the second detection point 45 is switched on, it indicates that there is already a lot of lint attached to the lint filtering device, and the lint filtering device should be cleaned. At this time, the cleaning device is started to clean the lint filtering device. As the cleaning progresses, the lint on the lint filtering device is gradually removed, and then the second detection point 45 is disconnected. At this time, it indicates that the lint filtering device has restored its cleaning ability. At this time, the cleaning device stops cleaning the lint filtering device.

[0065] Embodiment Three

[0066] As Figure 3 shown, the difference between the laundry treatment device in this embodiment and the above embodiment is that: the position detection device includes a reset member for restoring the detection connecting piece to its initial position, thereby disconnecting between the detection point and the controller and generating a corresponding signal, so that the cleaning device adjusts the cleaning method / ends the cleaning operation. The cleaning method includes the selection of the cleaning angle and / or the cleaning intensity and / or the cleaning medium.

[0067] With the laundry treatment device introduced in the present invention, a reset device is provided so that after the detection is completed or after the laundry treatment device stops working, the position detection device can be reset, ensuring the accuracy of the next detection and at the same time resetting the lint filtering device, thereby enabling the user to conveniently remove it.

[0068] Furthermore, the cleaning method in this embodiment includes the selection of cleaning angle and / or cleaning intensity and / or cleaning medium, and the cleaning medium includes gas and / or liquid.

[0069] With the laundry treatment device introduced in the present invention, the selection of the spraying medium is diverse, and multiple media can be used selectively or alternately. For example, an operation of spraying liquid can be performed on the lint filtering device at the initial stage when it starts to work. When the degree of change in the position state of the lint filtering device is alleviated and the change amount of the position state is reduced to a certain value, the cleaning device then adjusts the spraying medium to gas, so that the cleaning of the lint filtering device is based on meeting the filtering function of the lint filtering device itself, avoiding affecting the cleaning function of the lint filtering device during the cleaning process.

[0070] Embodiment Four

[0071] The difference between the laundry treatment device described in this embodiment and the above embodiment is that: the cleaning device includes a first cleaning unit and a second cleaning unit, the cleaning medium of the first cleaning unit is liquid, and the cleaning medium of the second cleaning unit is gas.

[0072] With the laundry treatment device introduced in the present invention, different cleaning devices are used to perform cleaning operations for different cleaning media. Preferably, the number of the first cleaning unit and / or the second cleaning unit is multiple, and they are arranged at intervals; then different cleaning devices are responsible for spraying different media, which can simplify the working mode of the control system. And by analogy, a third set of cleaning devices can be added for spraying special cleaning agents.

[0073] Embodiment Five

[0074] The difference between the laundry treatment device described in this embodiment and the above embodiment is that: in this embodiment, the lint filtering device is arranged on the laundry treatment device through the installation part. The number of the installation parts is multiple, and the multiple installation parts are respectively arranged at different positions.

[0075] Through the laundry treatment device introduced in the present invention, the connection function between the lint filtering device and the laundry treatment device is realized through the installation parts arranged at multiple points, so that the control of the lint filtering device by the device is multi-point control, which can make it more evenly and firmly connected to the device from multiple positions, ensuring that the position of the lint filtering device is more stable when the device is working; moreover, the device can obtain the data generated by the position change of the lint filtering device through system control to characterize the amount of lint attached to it.

[0076] Further, in this embodiment, the position detection device detects the position state of the lint filtering device by detecting the position change of the installation part. The position detection device is connected to the installation part.

[0077] Through the laundry treatment device introduced in the present invention, the installation part is reasonably designed. The installation part includes multiple mutually cooperating parts, so that it can generate corresponding signals according to the position of the lint filtering device, can not only detect whether the lint filtering device has a position change, but also detect the amount of position change of the lint filtering device, realizing qualitative and quantitative detection at the same time, enabling the device to make different degrees of adjustment according to different position offsets.

[0078] Embodiment Six

[0079] As Figure 4 shown, the difference between the laundry treatment device described in this embodiment and the above embodiment is that: the number of the cleaning devices 6 is multiple, and the positions of the multiple cleaning devices 6 relative to the lint filtering device 1 are different. At least one of the multiple cleaning devices 6 is arranged above the lint filtering device 1. The cleaning device includes a guiding part 62 for guiding the cleaning medium and a spraying part 61 for spraying the cleaning medium. At least two of the multiple cleaning devices determine the timing of starting and / or adjusting and / or ending the cleaning operation differently according to the detection result of the position detection device, so that at least two of the multiple cleaning devices perform the cleaning operations asynchronously.

[0080] Then, in actual use, the opening sequence of the multiple cleaning devices can be adjusted. Since the cleaning range of each cleaning device is different, different areas of the lint filtering device can be cleaned at different times. Then it is ensured that when the lint filtering device is cleaned, at least one part of the lint filtering device is in a state of not being cleaned, and the lint filtering function of this part is complete, which can ensure that the filtering effect of the lint filtering device can be fully exerted even when it is being cleaned.

[0081] Embodiment Seven

[0082] The difference between the laundry treatment device in this embodiment and the above embodiment is that: the control system of the device obtains the cleanliness of the lint filter device according to the detection result of the position detection device and / or the working state of the cleaning device. The control system displays the cleanliness of the lint filter device to the user after the laundry treatment device finishes the laundry treatment operation.

[0083] Through the laundry treatment device introduced in the present invention, the cleanliness of the lint filter device is obtained according to the detection result of the vibration detection device and / or the working state of the cleaning device, and the cleanliness is fed back to the user, so that the user can have an intuitive feeling about the cleaning condition of the lint filter device, and ensure that the user grasps the working condition of the lint filter device and the working condition of the cleaning device.

[0084] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent can make some changes or modifications to the above-mentioned technical content as equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention.
