Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a clothing processing device and control method with indoor dehumidification function. Background Technology

[0002] As people's living standards gradually improve, clothes dryers have begun to enter people's lives and play an important role. However, existing clothes dryers can only dry clothes and have limited functionality. In areas with continuous days of seasonal damp weather, in addition to the difficulty in drying clothes, the damp indoor environment also causes some problems for users. Long-term dampness can easily breed bacteria, causing skin and respiratory infections, as well as mold growth in the home, which is detrimental to people's health.

[0003] Existing washing and drying devices are only used for washing and drying clothes, and have a single function. For example, the invention patent with application number CN201310451914.5 discloses a condenser dryer with air damper switching, which includes a drying air path. The drying air path is composed of a drum, a drum air outlet, a front air duct, a condenser, a rear air duct, and a drum air inlet connected in sequence. The front air duct is provided with a first air damper, which is used to switch the connection between the front air duct and the external environment and the connection between the front air duct and the drying air path. The rear air duct is provided with a second air damper for connecting and disconnecting the rear air duct from the external environment.

[0004] The aforementioned condenser dryer incorporates a first and second air damper in its drying airflow path, and a sensor on the dryer detects the dryness of the clothes. Based on the parameters detected by the sensor, the first and second air dampers are controlled to open and close. While this achieves switching between a closed-loop and open-loop drying airflow path and controls the opening and closing of the condenser, resulting in time-saving and energy-efficient operation, it suffers from excessively long idle time when not performing drying operations. Therefore, to improve the efficiency of washer-dryer combos, a washer-dryer combo with indoor dehumidification function needs to be researched, aiming to both dry clothes and improve the indoor environment. Furthermore, to improve the intelligence level of indoor dehumidification in, for example, drum-type washer-dryer combos, while achieving both drying and dehumidification, existing technologies still suffer from the problem of the dehumidification program failing to execute properly due to accidental door closure or insufficient opening angle.

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

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clothing treatment device and control method with indoor dehumidification function.

[0007] By adopting this control method, after receiving a request to start the indoor dehumidification program, the system selects whether to start the program based on the door's status. This effectively avoids the phenomenon that the indoor dehumidification program cannot be executed normally due to the door being accidentally closed or opened at too small an angle, thus improving the efficiency of indoor dehumidification.

[0008] To achieve this objective, according to one aspect of the present invention, the present invention adopts the following technical solution:

[0009] A control method for a clothing handling device with indoor dehumidification function, wherein the clothing handling device has a clothing inlet and a door that can be opened and closed is provided on the clothing inlet.

[0010] The control method includes: after receiving a signal to start the indoor dehumidification program, the clothing handling device determines whether the door is open. If so, the indoor dehumidification program is started normally; otherwise, the user is prompted.

[0011] Furthermore, after receiving the signal to start the indoor dehumidification program, the clothing handling device starts the indoor dehumidification program normally when it determines that the door is open at an angle greater than or equal to a preset angle.

[0012] Furthermore, the control method of the clothing handling device includes: receiving a signal to start the indoor dehumidification program; determining the door lock status; if the door lock is determined to be in a locked state, directly controlling the door lock to be powered off and unlocked, and controlling the door to open automatically.

[0013] Preferably, after the door opens automatically, it is further determined whether the opening angle of the door is greater than or equal to the preset angle; if so, the indoor dehumidification program is started normally; if not, the user is prompted.

[0014] Furthermore, if it is determined that the door lock is already in a power-off unlocked state, then it is directly determined whether the opening angle of the door is greater than or equal to the preset angle.

[0015] Furthermore, if it is determined that the door is opened at an angle less than the preset angle, the user is prompted to further open the door and / or the indoor dehumidification program is paused.

[0016] Preferably, the clothing handling device alerts the user via voice alarm and / or flashing lights.

[0017] Furthermore, the garment handling device includes a local control mode and a remote control mode controlled remotely via a terminal device.

[0018] Preferably, after receiving a request from the local end or terminal device to start the indoor dehumidification program, the clothing handling device controls whether to start the indoor dehumidification program based on the door status of the clothing handling device.

[0019] More preferably, the local end or terminal device of the clothing processing device can be configured to send a request to the clothing processing device to start the indoor dehumidification program at a predetermined time.

[0020] Furthermore, when it is determined that the opening angle of the door is greater than or equal to the preset angle, the indoor dehumidification program is started normally. The indoor dehumidification program includes a heat pump dehumidification drying step or a condensation dehumidification drying step.

[0021] Preferably, the heat pump dehumidification and drying step includes: controlling the compressor to start, the humid air being processed sequentially by the evaporator and condenser to obtain dry air, which is then delivered to the inner drum of the clothing processing device and diffused into the indoor environment through the clothing inlet.

[0022] Preferably, the condensation dehumidification and drying step includes: controlling the heating unit to turn on, and the humid air is processed by the condensation channel and the heating unit in sequence to obtain dry air, which is then transported to the inner drum of the clothing processing device and diffused into the indoor environment through the clothing inlet.

[0023] Another objective of this invention is to provide a clothing treatment device with an indoor dehumidification function, employing the control method described above for such a clothing treatment device with an indoor dehumidification function.

[0024] Furthermore, the garment handling device includes: a control unit; an alarm unit for issuing a prompt message to the user; and a door position detection unit for detecting the door information of the garment handling device and feeding back the detection result to the control unit.

[0025] A third objective of the present invention is to provide a terminal device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of a control method for the garment handling device.

[0026] A fourth objective of the present invention is to provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of a control method for a clothing handling device.

[0027] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0028] 1. The clothing handling device with indoor dehumidification function provided by the present invention, by adopting the above-mentioned control method, after receiving a request to start the indoor dehumidification program, selects whether to start the indoor dehumidification program according to the state of the door, effectively avoiding the phenomenon that the indoor dehumidification program cannot be executed normally due to the door being accidentally closed or the opening angle being too small, thereby improving the efficiency of indoor dehumidification.

[0029] 2. The clothing dehumidification device with indoor dehumidification function provided by the present invention can dehumidify indoor air, improve the efficiency of household appliances, achieve the effect of multiple uses in one machine, and save space for placing single-function appliances.

[0041] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0042] 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.

[0043] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection 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.

[0045] Existing washer-dryer combos are mostly placed in bathrooms, kitchens, balconies, etc., and are only used for washing and drying clothes. When the humidity in these spaces is high, ordinary exhaust systems are used for air exchange, or dehumidifiers or air conditioners are used at a distance. However, when the outside humidity is also high, and the dehumidifiers or air conditioners are installed in distant locations such as living rooms or bedrooms, it is difficult to handle the humid air in these spaces, which is detrimental to human health and the environment. This invention enables washer-dryer combos to dehumidify the corresponding spaces during their idle periods when they are not used for clothes washing and drying, achieving multiple uses in one machine and saving space.

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

[0047] like Figure 1-5 As shown, a control method for a clothing handling device with indoor dehumidification function is disclosed. The clothing handling device has a clothing inlet, and a door is provided on the clothing inlet that can be opened and closed.

[0048] The control method includes: after receiving a signal to start the indoor dehumidification program, the clothing handling device determines whether the door is open. If so, the indoor dehumidification program is started normally; otherwise, the user is prompted.

[0049] Furthermore, after receiving a signal to start the indoor dehumidification program, the clothing handling device will start the indoor dehumidification program normally when it determines that the door is open at an angle greater than or equal to a preset angle. The preset angle can be 30°, 45°, or 180°. It is understood that the larger the preset angle, the higher the efficiency of air exchange between the inner drum of the clothing handling device and the outside air, and the higher the dehumidification efficiency.

[0050] Furthermore, the control method for the clothing handling device includes: receiving a signal to start the indoor dehumidification program; determining the door lock status; if the door lock is determined to be locked, directly controlling the door lock to power off and unlock, and controlling the door to open automatically. After controlling the door to open automatically, further determining whether the opening angle of the door is greater than or equal to a preset angle; if so, then starting the indoor dehumidification program normally; if not, then prompting the user.

[0051] Furthermore, if it is determined that the door lock is already in a power-off unlocked state, then it directly checks whether the door opening angle is greater than or equal to a preset angle. If yes, the indoor dehumidification program is started normally; if not, the user is prompted.

[0052] Furthermore, if it is determined that the door is opened at an angle less than the preset angle, the user is prompted to further open the door and / or the indoor dehumidification program is paused.

[0053] Preferably, the garment handling device alerts the user via voice alarm and / or flashing lights. Of course, the methods of alerting the user can be varied and can even be customized according to the user's preferences. For ease of understanding, this embodiment only illustrates alerting the user via voice alarm and / or flashing lights.

[0054] Furthermore, the garment handling device includes a local control mode and / or a remote control mode controlled remotely via a terminal device. Preferably, after receiving a request from the local device or terminal device to start the indoor dehumidification program, the garment handling device controls whether to start the indoor dehumidification program based on the door status of the garment handling device. More preferably, the local device or terminal device of the garment handling device can be configured to send a request to start the indoor dehumidification program to the garment handling device at a predetermined time.

[0055] It should be explained that the local control mode can be understood as using the local terminal (which can be understood as a time setting device) to preset the time of the indoor dehumidification program to be carried out, for example, setting it to start after two hours or ten hours.

[0056] The remote control mode via terminal device can be understood as sending a signal to the clothing dehumidifier to start the indoor dehumidification program. This indicates that the control method also includes remotely controlling the clothing dehumidifier to dehumidify the room. This improves the intelligence and convenience of the clothing dehumidifier and enhances the user experience.

[0057] Furthermore, the terminal device allows users to preset the time for the indoor dehumidification program, such as setting it to start after two or ten hours. This terminal device not only enables remote control but also allows for time setting.

[0058] At this point, it is important to understand that the indoor dehumidification program can be understood as the heat pump dehumidification and drying steps or the condensation dehumidification and drying steps that will be described below. It can also be understood as the above-mentioned start-up, judgment, and prompting steps before the heat pump dehumidification and drying steps or the condensation dehumidification and drying steps. In general, the indoor dehumidification program and the above-mentioned start-up, judgment, and prompting steps all belong to the control method of the clothing treatment device with indoor dehumidification function.

[0059] Furthermore, when it is determined that the opening angle of the door is greater than or equal to the preset angle, the indoor dehumidification program is started normally. The indoor dehumidification program includes a heat pump dehumidification drying step or a condensation dehumidification drying step.

[0060] Preferably, the heat pump dehumidification and drying step includes: controlling the compressor to start, the humid air being processed sequentially by the evaporator and condenser to obtain dry air, which is then delivered to the inner drum of the clothing processing device and diffused into the indoor environment through the clothing inlet.

[0061] Preferably, the condensation dehumidification and drying step includes: controlling the heating unit to turn on, and the humid air is processed by the condensation channel and the heating unit in sequence to obtain dry air, which is then transported to the inner drum of the clothing processing device and diffused into the indoor environment through the clothing inlet.

[0062] like Figure 6 and 7 As shown, another objective of the present invention is to provide a clothing treatment device with an indoor dehumidification function, employing the control method of the clothing treatment device with an indoor dehumidification function as described above.

[0063] Furthermore, the garment handling device includes: a control unit; an alarm unit for issuing prompts to the user; and a door position detection unit for detecting the door information of the garment handling device and feeding back the detection results to the control unit.

[0064] like Figure 8 As shown, the door position detection unit includes an obstruction sensor 97. The obstruction sensor 97 is used to determine whether the observation window 92 is open. The obstruction sensor 97 can be a diffuse reflective photoelectric type. Once the door opening angle is less than the preset angle, the light emitted by the switch will return, and the obstruction sensor 97 will be disconnected. There is no need to install a reflector on the door.

[0065] A photoelectric sensor is a sensor that uses photoelectric elements as its detection element. It first converts the change in the measured quantity into a change in a light signal, and then, with the help of photoelectric elements, further converts the light signal into an electrical signal. Photoelectric sensors can be classified in several ways: slotted photoelectric sensors, through-beam photoelectric sensors, reflector-type photoelectric switches, and diffuse reflective photoelectric switches. The occlusion sensor 97 belongs to the photoelectric sensor category.

[0066] Through-beam type: Used with a projector and a receiver. Longest detection distance, requires installation on both sides and both need power. Can be installed with a slit (for detecting small objects; no strict requirements on object color). Requires optical axis alignment, high cost. Retroreflective type: Must be used with a reflector. Shorter detection distance than through-beam type, requires installation on both sides. Recommended for detecting transparent objects. If the object is a highly reflective mirror, a retroreflective photoelectric sensor with MSR function is recommended. Requires optical axis alignment, lower cost than through-beam type. Diffuse reflective type: Used alone. Can be installed on one side. Requirements for the object being detected: large, light-colored, flat, and opaque. Shortest detection distance. Does not require optical axis alignment, low cost. The standard detection distance in the data is based on 100*100mm white paper. If the object being detected differs from the standard object, the detection distance will be different; specific distances need to be determined experimentally.

[0067] During the dehumidification process of the clothing processing device, the observation window 92 is open. To prevent pets or children from accidentally entering the clothing processing device and causing danger, the infrared sensor 91 needs to perform real-time scanning and detection. Once an abnormality is detected, the infrared sensor 91 sends a signal to the control board (control unit 81), triggering an alarm and cutting off the power.

[0068] The infrared sensor 91 also has the function of detecting the temperature of the garment handling device's inlet, preventing potential harm to the user due to excessively high inlet temperature; it also determines whether the temperature value exceeds the preset value at the end of the environmental dehumidification mode and the garment drying mode. To minimize the risk of accidents, the infrared sensor 91 is mounted in a strip shape on the upper side of the inner frame 95 of the garment handling device, which facilitates maximum scanning of the inlet temperature.

[0069] In this embodiment, the door lock adopts an automatic pop-opening device, which can be a magnetic door switch. Once the dehumidification program is selected, the controller issues a command to cut off the power to the door lock. The spring installed on the hinge seat is in a compressed state, which will apply an external elastic force to the observation window, causing the observation window to automatically pop open at a preset angle, such as 35°.

[0070] Example 1

[0071] like Figure 1 As shown, the clothing handling device with indoor dehumidification function in this embodiment is a washer-dryer combo. The method for controlling the washer-dryer combo may include the following steps:

[0072] Step S20: Receive a signal to start the indoor dehumidification program;

[0073] Step S30: Determine the door lock status;

[0074] If it is determined that the door lock is locked, proceed to step S40: directly control the door lock to power off and unlock, and control the door to open automatically;

[0075] If it is determined that the door lock is in a power-off unlocked state, then step S50: directly determine whether the opening angle of the door is greater than or equal to the preset angle.

[0076] Similarly, after the door opens automatically, step S50 is performed: determine whether the opening angle of the door is greater than or equal to the preset angle.

[0077] If the door opens at an angle greater than or equal to the preset angle, proceed to step S60: Start the indoor dehumidification program normally;

[0078] If the door opens at an angle less than the preset angle, proceed to step S70: prompt the user.

[0079] like Figure 2 As shown, the control method for this washer-dryer combo may also include the following steps:

[0080] Step S20: Receive a signal to start the indoor dehumidification program;

[0081] Step S30: Determine the door lock status;

[0082] If it is determined that the door lock is locked, proceed to step S40: directly control the door lock to power off and unlock, and control the door to open automatically;

[0083] If it is determined that the door lock is in a power-off unlocked state, then step S50: directly determine whether the opening angle of the door is greater than or equal to the preset angle.

[0084] Similarly, after the door opens automatically, step S50 is performed: determine whether the opening angle of the door is greater than or equal to the preset angle.

[0085] If the door opens at an angle greater than or equal to the preset angle, proceed to step S60: Start the indoor dehumidification program normally;

[0086] If the door opens to an angle less than the preset angle, proceed to step S70: prompt the user to open the door further;

[0087] Step S701: Determine whether the user opens the door within the preset time period;

[0088] If the user opens the door within the preset time period, and the door opens at an angle greater than or equal to the preset angle, then proceed to step S60: Start the indoor dehumidification program normally.

[0089] If the user does not open the door within the preset time period, proceed to step S702: suspend the indoor dehumidification program.

[0090] It should be understood that the step of determining whether the door opening angle is greater than or equal to the preset angle is not limited to the specific logical steps mentioned above. This step can be added whenever it is necessary to determine whether the door opening angle is greater than or equal to the preset angle; there is no limitation here.

[0091] Example 2

[0092] like Figure 3 As shown, the clothing processing device with indoor dehumidification function in this embodiment is a clothes dryer, and the method of controlling the clothes dryer may include the following steps:

[0093] Step S10: The local device or terminal device sends a request to start the indoor dehumidification program;

[0094] Step S20: Receive a signal to start the indoor dehumidification program;

[0095] Step S30: Determine the door lock status;

[0096] If it is determined that the door lock is locked, proceed to step S40: directly control the door lock to power off and unlock, and control the door to open automatically;

[0097] If it is determined that the door lock is in a power-off unlocked state, then step S50: directly determine whether the opening angle of the door is greater than or equal to the preset angle.

[0098] Similarly, after the door opens automatically, step S50 is performed: determine whether the opening angle of the door is greater than or equal to the preset angle.

[0099] If the door opens at an angle greater than or equal to the preset angle, proceed to step S60: Start the indoor dehumidification program normally;

[0100] If the door opens at an angle less than the preset angle, proceed to step S70: prompt the user.

[0101] Example 3

[0102] In this embodiment, the clothing handling device with indoor dehumidification function is a washer-dryer combo or a dryer. Based on the steps of Embodiment 1 or Embodiment 2, the method of controlling the washer-dryer combo or dryer may further include the following steps.

[0103] like Figure 4 As shown, when the door is determined to be open at an angle greater than or equal to a preset angle, the indoor dehumidification program is started normally. The indoor dehumidification program includes a heat pump dehumidification and drying step, which may further include the following sub-steps:

[0104] Sub-step S601a: Control the compressor to start, and the humid air is processed by the evaporator and condenser in sequence to obtain dry air, which is then delivered to the inner drum of the clothing processing device and diffused into the indoor environment through the clothing inlet.

[0105] Specifically, the workflow of a heat pump washer-dryer combo or dryer is as follows: humid air – evaporator – condenser – fan – dry air.

[0106] Furthermore, when the controller determines that the opening angle of the door is greater than or equal to the preset angle, it issues a command to the compressor, which then starts working. The evaporator temperature drops, releasing moisture from the air. After dehumidification, the air is sent to the inner cylinder by the fan through the condenser. The dry air is then continuously diffused to the outside through the inner cylinder, achieving the dehumidification effect.

[0107] like Figure 5 As shown, the indoor dehumidification process includes a condensation dehumidification and drying step. The condensation dehumidification and drying step may further include the following sub-steps:

[0108] Sub-step S601b: Control the heating unit to turn on. After the humid air passes through the condensation channel and the heating unit in sequence, it becomes dry air and is delivered to the inner drum of the clothing processing device, and diffused into the indoor environment through the clothing inlet.

[0109] Specifically, the workflow of a condenser washer-dryer or dryer is as follows: humid air → condenser channel → heating wire → fan → dry air.

[0110] Furthermore, when the controller determines that the door is open at an angle greater than or equal to a preset angle, it sends a command to the fan and heating wire. The fan / heating wire then starts working, and the humid air is condensed through the condensation channel to remove moisture from the air. The dry air is then sent to the front end of the inner cylinder by the fan and diffused to the outside, achieving the dehumidification effect.

[0111] Example 4

[0112] like Figure 6 As shown, a washer-dryer combo 80 with indoor dehumidification function includes a control unit 81; an alarm unit 82 for issuing alerts to the user; and a door position detection unit 83 for detecting the door information of the clothing handling device and feeding back the detection results to the control unit. The door position detection unit 83 may include an obstruction sensor 97.

[0113] Example 5

[0114] like Figure 7 As shown, a clothes dryer 80 with indoor dehumidification function includes a control unit 81; an alarm unit 82 for issuing prompts to the user; and a door position detection unit 83 for detecting the door information of the clothes handling device and feeding the detection results back to the control unit. A terminal device 84 is used to send a request to the control unit 81 to start the indoor dehumidification program, and can communicate wirelessly to achieve remote control.

[0115] This embodiment not only enables intelligent and automated indoor dehumidification of a low-efficiency device with a drying function, but also allows for remote control of the device and time setting, improving the user experience and allowing users to control the device anytime, anywhere.

[0116] Example 6

[0117] like Figure 8 As shown, a drum-type washer-dryer using the control methods of Embodiments 1 to 3 includes a housing 90, a dispensing port on the housing, an inner frame 95 around the dispensing port, an observation window 92 connected to the inner frame 95 via a spring 93 on a hinge seat 94, and an automatic pop-up device 96, a blocking sensor 97, and an infrared sensor 91 on the inner frame 95.

[0118] The occlusion sensor 97 is used to determine whether the observation window 92 is open. The occlusion sensor 97 can be a diffuse reflective photoelectric type. Once the door is opened at an angle less than the preset angle, the light emitted by the switch will return, and the occlusion sensor 97 will be disconnected. There is no need to install a reflector on the door.

[0119] During the dehumidification process of the drum washer-dryer, the observation window 92 is open. To prevent pets or children from accidentally entering the dryer and causing danger, the infrared sensor 91 needs to perform real-time scanning and detection. Once an abnormality is detected, the infrared sensor 91 sends a signal to the control board (control unit 81), triggering an alarm and cutting off the power.

[0120] The infrared sensor 91 also detects the temperature of the inlet of the drum washer-dryer to prevent users from being harmed by excessively high inlet temperatures; it also determines whether the temperature exceeds the preset value at the end of the dehumidification mode and the clothes drying mode. To minimize the risk of accidents, the infrared sensor 91 is mounted in a strip on the upper side of the inner frame 95 of the drum washer-dryer, which facilitates the scanning of the inlet temperature to the greatest extent.

[0121] In this embodiment, the door lock uses an automatic pop-opening device 96, which can be a magnetic door switch. Once the dehumidification program is selected, the controller sends a command to cut off the power to the door lock. The spring 93 installed on the hinge seat 94 is in a compressed state, which will apply an external elastic force to the observation window, causing the observation window to automatically pop open at a preset angle.

[0122] The clothing dehumidification device with indoor dehumidification function provided by the present invention, by adopting the above-mentioned control method, can judge the state of the door after receiving the signal to start the indoor dehumidification program, and then carry out the indoor dehumidification program; it improves the efficiency of household appliances; achieves the effect of one machine serving multiple purposes, and saves space for placing single-function appliances.

[0123] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. 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. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
