Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a door system for household appliances. The present invention also relates to a control method for a door body of a door system for household appliances and a corresponding household appliance. Background Art

[0002] In recent years, with the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for the intelligence and functionality of household appliances. It has become a trend to realize automatic door opening after the operation program of household appliances ends. However, the door system of existing household appliances can only realize one automatic door opening state of the door body, which cannot meet the needs of users. Summary of the invention

[0003] Therefore, an object of an embodiment of the present invention is to provide an improved door system for a household appliance, wherein the door system can flexibly meet different requirements of users regarding the opening state of the door body.

[0004] According to a first aspect of the present invention, there is provided a door system for a household appliance, wherein the door system comprises at least:

[0005] - a door body, the door body being configured to be rotatably connected to the main body of the household appliance via a rotating mechanism;

[0006] - a driving module, the driving module being independent of the rotating mechanism and being configured to be disposed in the main body and cooperate with the door body so as to rotate the door body relative to the main body; and

[0007] - a control module, the control module is electrically connected to the driving module and is configured to control the rotation angle of the door body relative to the main body by controlling the driving module to achieve different opening states of the door body.

[0008] Compared with the prior art, in the door system for household appliances according to the present invention, according to the control instructions of the control module, the door body can achieve different rotation angles relative to the main body of the household appliance under the drive of the driving module, thereby achieving different opening states of the door body, so that the user can flexibly adjust the opening state of the door body according to actual needs.

[0009] Exemplarily, the open state of the door body includes a closed state, at least one intermediate state and a fully open state, wherein in the intermediate state, the rotation angle of the door body relative to the main body is less than the maximum rotation angle that the door body can reach under the action of the driving module. By setting the intermediate state, the high temperature and high humidity atmosphere in the working space of the household appliance can be eliminated, thereby preventing the breeding of bacteria and the generation of odors, and can also effectively avoid the door body from opening at an excessive angle and preventing the door body from colliding with objects in the environment, and reducing the risk of objects falling from the working space of the household appliance.

[0010] Exemplarily, the driving module is configured with a driving mechanism and at least one ejector rod, wherein the ejector rod is configured to extend from the main body under the action of the driving mechanism and act on the door body to rotate the door body relative to the main body, thereby enabling the door body to be automatically opened in a simple and direct manner by the ejector rod.

[0011] For example, in the intermediate state, the door body can be kept at a preset rotation angle relative to the main body, which can effectively prevent the door body from shaking or swaying unexpectedly in the intermediate state.

[0012] Exemplarily, the ejection distance of the ejector rod in the intermediate state can be preset, which allows the user to adjust the opening angle of the door body in the intermediate state to achieve a desired opening state.

[0013] Exemplarily, with respect to the center of the door body, the ejector rod is arranged adjacent to the rotating mechanism on the inner side of the rotating mechanism. This allows the rotation of the door body to be controlled by a relatively small linear movement of the ejector rod.

[0014] Exemplarily, at least one first magnetic attraction portion is provided in the door body, and a second magnetic attraction portion is provided at the end of the ejection rod facing the door body, and the second magnetic attraction portion is configured to interact with the first magnetic attraction portion. The interaction between the first magnetic attraction portion and the second magnetic attraction portion can make the door body more stable during the opening process and ensure that it is stable at a preset rotation angle in the intermediate state.

[0015] Exemplarily, in the intermediate state or the fully open state, the ejector rod is retracted toward the main body to an initial position, which can prevent the ejector rod from being damaged when the user closes the door body.

[0016] Exemplarily, the drive mechanism has a drive motor and a transmission assembly, wherein the drive motor is controlled by the control module and its output shaft is meshingly connected to the transmission assembly, and the transmission assembly can drive the ejector rod to reciprocate linearly, wherein the drive mechanism also has a clutch, and the clutch is configured to control the connection and separation between the transmission assembly and the ejector rod.

[0017] Exemplarily, the driving module has two ejector rods, which are respectively operatively connected to the driving mechanism. The two ejector rods can make the driving movement of the door body more stable.

[0018] Exemplarily, in the intermediate state, the first magnetic attraction portion and the second magnetic attraction portion remain attracted to each other, thereby keeping the ejection rod and the door body connected in the intermediate state and reliably keeping the door body at a preset rotation angle.

[0019] Exemplarily, in the fully open state, the rotation distance of the door body relative to the main body at the position corresponding to the ejection rod is greater than the maximum ejection distance of the ejection rod, and the adsorption effect between the first magnetic attraction part and the second magnetic attraction part disappears; and / or, at least one of the first magnetic attraction part and the second magnetic attraction part is configured as an electromagnet, and the electromagnet is configured as follows: in the fully open state, the electromagnet loses its magnetism by power failure, so that the adsorption effect between the first magnetic attraction part and the second magnetic attraction part disappears; or, the electromagnet changes its magnetism by reverse power supply, so that there is a repulsive effect between the first magnetic attraction part and the second magnetic attraction part. This enables the door body to achieve a large rotation angle in the fully open state and to be disconnected from the drive module. In this case, the user can rotate the door body without hindrance, thereby conveniently taking out items from the working space of the household appliance.

[0020] Exemplarily, the door system includes a door hook disposed on the door body and a locking mechanism disposed on the main body, and the locking and unlocking of the door hook in the locking mechanism are controlled by the control module.

[0021] Exemplarily, the door system includes a signal acquisition module, which is electrically connected to the control module and is configured to detect an opening state signal of the door body, and the control module determines the opening state of the door body according to the opening state signal. Thus, the opening state of the door body can be obtained and corresponding operations can be performed according to the opening state.

[0022] Exemplarily, the signal acquisition module includes at least one of the following sensors: a door hook detection sensor, which is configured to determine whether the door hook provided on the door body is locked into the locking hole of the locking mechanism provided on the main body, so as to determine whether the door body is in a closed state; a distance sensor, which is configured to detect the distance of the door body relative to the main body, so as to determine the open state of the door body according to the distance; a rotation sensor, which is configured to detect the degree of rotation of the door body relative to the main body, so as to determine the open state of the door body according to the degree of rotation. This can detect the open state of the door body in different ways according to actual needs.

[0023] Exemplarily, the door hook detection sensor is provided with a signal generating unit, and when the door hook is locked into the locking hole of the locking mechanism, the signal generating unit generates a locking signal and sends the locking signal to the control module.

[0024] Exemplarily, the distance sensor includes a Hall element arranged in the main body and a Hall magnet arranged in the door body, the Hall element is configured to detect the magnetic field strength of the Hall magnet, and the distance of the door body relative to the main body can be determined by the magnetic field strength, wherein when the door body is in a closed state, the Hall element and the Hall magnet face each other.

[0025] Exemplarily, the rotation sensor is configured as a sliding resistor, and a resistance value of the sliding resistor depends on the opening degree of the door body.

[0026] Exemplarily, the control module is configured to, when receiving a lock signal generated by the signal generating unit and the magnetic field strength of the Hall magnet detected by the Hall element is greater than a first magnetic field strength threshold and / or the resistance value detected by the rotation sensor is less than a first resistance threshold, judge that the door body is in a closed state; when not receiving the lock signal and the magnetic field strength of the Hall magnet detected by the Hall element is between the first magnetic field strength threshold and the second magnetic field strength threshold and / or the resistance value detected by the rotation sensor is between the first resistance threshold and the second resistance threshold, judge that the door body is in an intermediate state; when not receiving the lock signal and the magnetic field strength of the Hall magnet detected by the Hall element is less than the second magnetic field strength threshold and / or the resistance value detected by the rotation sensor is greater than the second resistance threshold, judge that the door body is in a fully open state.

[0027] Exemplarily, the door system comprises an interaction module, which is communicatively connected with the control module and is configured to display the state of the door body and / or input control instructions for the door system.

[0028] According to a second aspect of the present invention, a method for controlling a door body of a door system for a household appliance is provided, wherein the control method is implemented by the door system according to the present invention, wherein the control method comprises at least the following steps:

[0029] S1: Obtaining a control instruction for the opening state of the door body of the door system;

[0030] S2: Controlling the rotation angle of the door body relative to the main body according to the control instruction to achieve different opening states of the door body.

[0031] Exemplarily, the control method further includes step S0 implemented before step S1: detecting a current opening state of the door body, and prompting a user of an achievable opening state based on the current opening state, wherein the achievable opening state is different from the current opening state.

[0032] Exemplarily, the control method further includes step S3 implemented after step S2: detecting the current opening state of the door body, and comparing the current opening state with the corresponding opening state to be achieved in the control instruction to confirm and provide feedback that the control instruction is correctly executed.

[0050] Figure 1 A schematic view of a household appliance 1000 according to an exemplary embodiment of the present invention is shown. Here, the household appliance 1000 is in particular a clothes processing device, such as a washing machine, a clothes dryer or a washer-dryer. However, it is also conceivable that the household appliance 1000 is a kitchen appliance, such as a microwave oven or a steam oven. The household appliance 1000 is mainly described below by taking a washing machine as an example.

[0051] like Figure 1 As shown, the household appliance 1000 includes a door system 100 and a main body 200, wherein the main body 200 assumes the main operating function of the household appliance 1000, such as a laundry processing function, and has an operating space, such as a washing space, and the door system 100 is configured to close and open the operating space. To this end, the door system 100 includes a door body 10, which is configured to be rotatably connected to the main body 200 of the household appliance 1000 through a rotating mechanism 20, closes the operating space of the main body 200 when it is abutted against the front plate of the main body 200, and opens the operating space when it leaves the main body 200. Exemplarily, the rotating mechanism 20 can be configured as a hinge mechanism, a hinge shaft is fixedly provided on one of the door body 10 and the main body 200, and an axis hole is fixedly provided on the other, and the rotation of the hinge shaft in the axis hole realizes the rotation of the door body 10 relative to the main body 200. It is also possible that the rotating mechanism 20 is configured as other mechanisms that are considered meaningful by those skilled in the art, such as a bearing mechanism. Here, the rotating mechanism 20 is arranged at the outer periphery of the door body 10 on the main extension plane of the door body 10 , which can effectively prevent the door body 10 from hitting the main body 200 during the opening process.

[0052] like Figure 1As shown, the door system 100 includes a driving module 30, which is disposed in the main body 200 and is arranged relatively independently from the rotating mechanism 20, wherein the driving module 30 is configured to cooperate with the door body 10 to rotate the door body 10 relative to the main body 200. Exemplarily, the driving module 30 has a driving mechanism 31 and at least one ejector rod 32, and the ejector rod can be extended from the main body 200 under the action of the driving mechanism 31 and act on, for example, press on the door body 10 to push the door body 10 to rotate relative to the main body 200, see Figure 2 For example, with respect to the center of the door body 10, the driving module 30, especially the ejector rod 32, is arranged adjacent to the rotating mechanism 20 on the inner side of the rotating mechanism 20, so that when the ejector rod 32 extends from the main body 200 and presses against the door body 10, it can control the rotation of the door body 10 around the rotating mechanism 20 through a relatively small linear motion, which can prevent the ejector rod 32 from being designed to be too long and effectively prevent the user from directly seeing or touching the ejector rod 32 to a certain extent.

[0053] like Figure 1 As shown, the door system 100 includes a control module 40, which is electrically connected to the drive module 30 and is configured to control or adjust the rotation angle of the door body 10 relative to the main body 200 by controlling the operation of the drive module 30 to achieve different opening states of the door body 10. Here, the control module 40 of the door system 100 can be integrated into the control unit of the household appliance 1000, for example, which can simplify the circuit design inside the household appliance 1000.

[0054] Exemplarily, the open state of the door body 10 includes a closed state, an intermediate state and a fully open state, wherein, in the closed state, the door body 10 is abutted against the main body 200 and closes the working space of the main body 200, and the door body 10 is not affected by the driving module 30; in the intermediate state, the door body 10 rotates relative to the main body 200 under the action of the driving module 30 and the rotation angle of the door body 10 relative to the main body 200 is less than the maximum rotation angle that the door body 10 can reach under the action of the driving module 30. In this case, the working space can be connected to the external environment to avoid the problem of breeding bacteria and odor in a closed environment with high temperature and high humidity, and the opening degree of the door body 10 can be accurately controlled, thereby preventing the door body 10 from colliding with other objects due to excessive opening, and reducing the risk of objects falling from the working space of the household appliance; in the fully open state, the rotation angle of the door body 10 relative to the main body 200 is greater than or equal to the maximum rotation angle that the door body 10 can reach under the action of the driving module 30, so that the working space of the main body 200 is completely open, which can facilitate users to take objects in the working space. It can be considered that the opening state of the door body 10 includes a plurality of intermediate states, in each of which the opening angle of the door body 10 relative to the main body 200 changes, thereby the opening degree of the door body 10 can be flexibly adjusted.

[0055] For example, in the intermediate state, the door body 10 can be kept at a preset rotation angle relative to the main body 200. This can reliably achieve the door body opening degree desired by the user and prevent the door body 10 from colliding with external objects as much as possible. To this end, the ejection distance of the ejection rod 32 in the intermediate state can be preset, and the ejection distance determines the rotation angle of the door body 10 relative to the main body 200.

[0056] For example, Figure 1 As shown, at least one first magnetic portion 11 is provided in the door body 10, and a second magnetic portion 33 is provided at the end of the ejection rod 32 facing the door body 10, the first magnetic portion 11 and the second magnetic portion 33 can interact with each other to make the door body 10 more stable during the opening process and ensure that it is firmly fixed at a preset rotation angle in the intermediate state, and further realize the mutual connection and disconnection of the door body 10 and the ejection rod 32.

[0057] Specifically, in the intermediate state of the door body 10, the first magnetic attraction portion 11 and the second magnetic attraction portion 33 remain attracted to each other, thereby enabling the door body 10 and the ejection rod 32 to be connected to each other through the magnetic attraction force between the first magnetic attraction portion 11 and the second magnetic attraction portion 33, so that when the ejection rod 32 reaches the preset ejection distance, the door body 10 is kept at a preset rotation angle relative to the main body 200. Further, in the fully opened state, the ejection distance of the ejection rod 32 continues to increase, and the first magnetic attraction portion 11 and the second magnetic attraction portion 33 are displaced due to relative movement, thereby breaking contact, and the adsorption effect between the two disappears, and the door body 10 is disconnected from the ejection rod 32 under the action of its own inertia, so that the rotation distance of the door body 10 relative to the main body 200 at the position corresponding to the ejection rod 32 is greater than the maximum ejection distance of the ejection rod 32, so that the working space of the main body 200 is fully open and convenient for users to take items in the working space. To this end, at least one of the first magnetic attraction portion 11 and the second magnetic attraction portion 33 is configured as an electromagnet, and the electromagnet is configured to generate magnetism opposite to that of the other magnetic attraction portion by powering on in the intermediate state, thereby generating an adsorption effect between the first magnetic attraction portion 11 and the second magnetic attraction portion 33, and lose magnetism by powering off in the fully open state, so that the adsorption effect between the first magnetic attraction portion 11 and the second magnetic attraction portion 33 disappears. In addition, it can also be considered that the electromagnet changes its magnetism by reverse powering on in the fully open state, so that the magnetism between the first magnetic attraction portion 11 and the second magnetic attraction portion 33 is the same and there is a repulsive effect, thereby prompting the door body 10 to rotate in a direction away from the ejection rod 32 and increasing the rotation angle of the door body 10 relative to the main body 200.

[0058] Figure 2 A schematic view of a drive module 30 of a door system 100 of a household appliance 1000 according to an exemplary embodiment of the present invention is shown.

[0059] like Figure 2 As shown, the driving module 30 has a driving mechanism 31 and two ejector rods 32, which are respectively connected to the driving mechanism 31 and can be extended from the driving module housing 36 under the drive of the driving mechanism 31 to simultaneously push the door body 10 to rotate, thereby improving the stability of the rotation process of the door body 10 and preventing the single ejector rod 32 from being subjected to excessive pressure. Here, the driving mechanism 31 has a driving motor 34 and a transmission assembly 35, the driving motor operates according to the control instruction of the control module 40 and its output shaft is meshed and connected with the transmission assembly 35, and the transmission assembly 35 is transmission-connected with the ejector rod 32 and can drive the ejector rod 32 to reciprocate linearly. Exemplarily, the transmission assembly 35 is constructed as a reduction gearbox, which is meshed and connected with the ejector rod 32 in the form of a gear rack or a screw nut through a multi-stage reduction gear.

[0060] Exemplarily, in the fully open state, the ejector rod 32 of the driving module 30 retracts to the initial position toward the main body 200. This can effectively prevent the door body 10 from colliding with the ejector rod 32 when the user manually closes the door body 10, thereby preventing the ejector rod 32 from bending or breaking.

[0061] like Figure 1 As shown, the door system 100 includes a door hook 51 arranged on the door body 10 and a locking mechanism 52 arranged on the main body 200. The locking and unlocking of the door hook 51 in the locking mechanism 52 can be controlled by the control module 40, which can prevent the door body 10 from accidentally opening in a closed state or during the normal operation of the household appliance 1000. Exemplarily, the door hook 51 is opposite to the rotating mechanism 20 on the main extension plane of the door body 10, wherein the locking mechanism 52 has a locking slider and a locking hole arranged on the locking slider, and the door hook 51 can extend into the locking hole to achieve a locking connection. Of course, other locking methods that are considered meaningful by those skilled in the art can also be considered.

[0062] Figure 3 A schematic block diagram of a door system 100 of a household appliance 1000 according to an exemplary embodiment of the present invention is shown.

[0063] like Figure 3 As shown, the door system 100 also includes a signal acquisition module 60, which is electrically connected to the control module 40 and is constructed to detect an opening status signal of the door body 10. The control module 40 determines the opening status of the door body 10 according to the opening status signal and controls the driving module 30 to achieve a desired opening angle of the door body 10 relative to the main body 200.

[0064] like Figure 1 and Figure 3 As shown, the signal acquisition module 60 includes a door hook detection sensor 61, which is configured to determine whether the door hook 51 provided on the door body 10 is locked in the locking hole of the locking mechanism 52 provided on the main body 200, so as to determine whether the door body 10 is in a closed state. For example, the door hook detection sensor 61 is provided with a signal generating unit, and when the door hook 51 is locked in the locking hole of the locking mechanism 52, the signal generating unit generates a locking signal and sends the locking signal to the control module 40. Here, the signal generating unit exemplarily includes two oppositely disposed electrical contacts, and one of the two electrical contacts is bent and deformed under the pressure of the door hook 51 when the door hook 51 is locked in the locking hole and is connected to the other electrical contact, thereby generating a locking signal. Of course, other configurations of the signal generating unit that are considered meaningful by those skilled in the art can also be considered.

[0065] like Figure 1 and Figure 3As shown, the signal acquisition module 60 includes a distance sensor 62, which is configured to detect the distance of the door body 10 relative to the main body 200 and send a signal about the distance to the control module 40, and the control module determines the opening state of the door body 10 according to the distance. Exemplarily, the distance sensor 62 includes a Hall element 64 arranged in the main body 200 and a Hall magnet 65 arranged in the door body 10, and the Hall element is configured to detect the magnetic field strength of the Hall magnet 65. The control module 40 can determine the distance of the door body 10 relative to the main body 200 by the magnetic field strength, wherein when the door body 10 is in a closed state, the Hall element 64 and the Hall magnet 65 face each other. In particular, the Hall element 64 is arranged above the locking mechanism 52, and the Hall magnet 65 is arranged above the door hook 51. Of course, other structural forms of the distance sensor 62 that are considered meaningful by those skilled in the art can also be considered, such as an infrared sensor.

[0066] like Figure 1 and Figure 3 As shown, the signal acquisition module 60 includes a rotation sensor 63, which is configured to detect the degree of rotation of the door body 10 relative to the main body 200, so as to determine the opening state of the door body 10 according to the degree of rotation. Exemplarily, the rotation sensor 63 can be configured as a sliding resistor, and the resistance value of the sliding resistor depends on the opening degree of the door body 10. As the rotation angle of the door body 10 relative to the main body 200 increases, the resistance value of the sliding resistor increases accordingly. In particular, the rotation sensor 63 is arranged on the rotating mechanism 20.

[0067] For example, Figure 3As shown, the control module 40 is electrically connected to the door hook detection sensor 61, the distance sensor 62 and the rotation sensor 63 of the signal acquisition module 60 respectively and receives the detection signals from each sensor. Here, the control module 40 is configured to judge that the door body 10 is in a closed state when the locking signal generated by the signal generating unit of the door hook detection sensor 61 is received and the magnetic field strength of the Hall magnet 65 detected by the Hall element 64 is greater than the first magnetic field strength threshold and / or the resistance value detected by the rotation sensor 63 is less than the first resistance threshold; when the locking signal is not received and the magnetic field strength of the Hall magnet 65 detected by the Hall element 64 is between the first magnetic field strength threshold and the second magnetic field strength threshold and / or the resistance value detected by the rotation sensor 63 is between the first resistance threshold and the second resistance threshold, the door body 10 is judged to be in an intermediate state; when the locking signal is not received and the magnetic field strength of the Hall magnet 65 detected by the Hall element 64 is less than the second magnetic field strength threshold and / or the resistance value detected by the rotation sensor 63 is greater than the second resistance threshold, the door body 10 is judged to be in a fully open state. Here, the first magnetic field strength threshold, the second magnetic field strength threshold, the first resistance threshold, and the second resistance threshold can be obtained from experimental data and / or empirical data and pre-stored in the control module 40. The open state of the door body 10 can be accurately determined by analyzing the detection signals of the door hook detection sensor 61, the distance sensor 62, and the rotation sensor 63. Of course, it is also conceivable that the control module 40 determines the open state of the door body 10 based only on the detection signals of one or two of the door hook detection sensor 61, the distance sensor 62, and the rotation sensor 63. It is also possible that the signal acquisition module 60 also includes other sensors that are considered meaningful by those skilled in the art.

[0068] For example, Figure 1 and Figure 3 As shown, the door system 100 includes an interaction module 70, which is communicatively connected to the control module 40 and is configured to at least display the state of the door body 10 and input control instructions for the door system 100. For example, the interaction module 70 may include an input element configured as a touch display screen, which is integrated on the main body 200, and the user can see the various state parameters of the household appliance 1000 including the door system 100 through the touch display screen and can input control instructions for presetting or changing the opening state of the door body 10. However, it is also conceivable that the input element of the interaction module 70 is a button, a knob or other touch element. In addition, it is also possible that the interaction module 70 includes a remote interaction device, such as a smart phone, which is connected to the control module 40 in a wireless communication manner, and the user can obtain the opening state of the door body 10 in real time through the remote interaction device and input control instructions for presetting or changing the opening state of the door body 10.

[0069] Figure 4 A control method of a door body 10 of a door system 100 for a household appliance 1000 according to an exemplary embodiment of the present invention is shown, the control method being implemented by the door system 100 according to the present invention. Figure 5a to Figure 5d Schematic views of different opening states of a door system 100 of a household appliance 1000 according to an exemplary embodiment of the present invention are respectively shown.

[0070] like Figure 4 As shown, the control method of the door body 10 of the door system 100 for the household appliance 1000 according to the present invention comprises at least the following steps:

[0071] S1: Obtaining a control instruction for the opening state of the door body 10 of the door system 100, wherein the control instruction may be preset before the operation program of the household appliance 1000 starts, such as automatically opening the door body 10 to an intermediate state immediately after the operation program ends, but it is also possible that the control instruction is directly input in real time by the user through the interaction module 70 or is built into the control program of the control module 40 by default;

[0072] S2: The control module 40 controls the driving module 30 according to the control instruction, thereby adjusting the rotation angle of the door body 10 relative to the main body 200 to achieve different opening states of the door body 10.

[0073] For example, Figure 4 As shown, the control method further includes step S0 implemented before step S1: the signal acquisition module 60 detects the current opening state of the door body 10, and based on the current opening state, prompts the user of an achievable opening state, and the achievable opening state is different from the current opening state. For example, when the detected current opening state is a closed state, the user is prompted that the achievable opening state is an intermediate state or a fully open state. This allows the user to input control instructions more clearly.

[0074] For example, Figure 4 As shown, the control method further includes step S3 implemented after step S2: the signal acquisition module 60 detects the current opening state of the door body 10, and compares the current opening state with the corresponding opening state to be realized in the control instruction to confirm and feedback that the control instruction is correctly executed. When the control instruction is not correctly executed, the user is prompted that the door body 10 cannot be opened normally.

[0075] Exemplarily, in step S1, an instruction for the end of the operation program of the household appliance 1000 is additionally obtained, and step S2 is performed only when the instruction for the end of the operation program is obtained. Specifically, the control instruction for the opening state of the door body 10 of the door system 100 is, for example, built into the control program of the control module 40 by default, and the control module 40 executes the control instruction for the door body 10 only when receiving the instruction for the end of the operation program of the household appliance 1000, such as the washing program, for example, the door body 10 is opened to the intermediate state immediately after the washing program ends. This can avoid hindering the normal operation of the operation program of the household appliance 1000.

[0076] like Figure 5a to Figure 5d As shown, the opening state of the door body 10 includes a closed state, at least one intermediate state and a fully open state.

[0077] like Figure 5a As shown, in the closed state, the door body 10 is against the front plate of the main body 200 and closes the working space of the main body 200. In particular, the door body 10 is provided with a door seal 12, and in the closed state of the door body 10, the door body 10 is sealed with respect to the main body 200 by the door seal. Here, when the door body 10 is in the closed state, the user is prompted by the interactive module 70 that an intermediate state or a fully open state can be achieved.

[0078] like Figure 5b and Figure 5c As shown, in the intermediate state, the rotation angle of the door body 10 relative to the main body 200 is less than the maximum rotation angle that the door body 10 can reach under the action of the driving module 30. Here, the rotation angle of the door body 10 relative to 200 can be adjusted and preset to achieve different opening degrees of the door body 10. For example, the door body 10 is Figure 5b The rotation angle in the first intermediate state is smaller than that in Figure 5cThe rotation angle in the second intermediate state. When the door body 10 is in the intermediate state, the user is prompted by the interactive module 70 that a fully open state or a closed state can be achieved. Here, in order to achieve the transition from the intermediate state to the closed state, the door body 10 can be driven to close automatically by the strong magnetic attraction between the first magnetic attraction part 11 of the door body 10 and the second magnetic attraction part 33 of the drive module 30 until the door hook 51 is locked in the locking mechanism 52. However, it is also possible to prompt the user to manually close the door body 10 through the interactive module 70, wherein the door body 10 can be manually rotated in the intermediate state, for example, in that the drive mechanism 31 also has a clutch, which is configured to achieve separation between the ejector rod 32 and the transmission assembly 35 in the intermediate state of the door body 10, thereby allowing the door body 10 to be closed under the manual action of the user until the door hook 51 is locked in the locking mechanism 52. However, it is also possible that in the intermediate state of the door body 10, the magnetic attraction between the first magnetic part 11 of the door body 10 and the second magnetic part 33 of the driving module 30 disappears and the ejection rod 32 retracts to the initial position toward the main body 200, which also allows the door body 10 to be transformed into a closed state under the manual action of the user.

[0079] like Figure 5d As shown, in the fully open state, the rotation distance of the door body 10 relative to the main body 200 at the position corresponding to the ejection rod 32 is greater than the maximum ejection distance of the ejection rod 32, so that the working space of the main body 200 is fully open. In this case, the user can easily take items from the working space. In particular, in the fully open state, the adsorption effect between the first magnetic attraction portion 11 and the second magnetic attraction portion 33 disappears and the ejection rod 32 retracts to the initial position toward the main body 200, so that the door body 10 cannot be automatically closed by the driving module 30. Exemplarily, when the door body 10 is in the fully open state, the user is prompted by the interactive module 70 to manually close the door body 10.

[0080] For example, when the user presets the open state before the operation program of the household appliance 1000 starts, the user is prompted to realize the closed state, the intermediate state or the fully open state through the interaction module 70. When the operation program of the household appliance 1000 ends, the control module 40 controls the door body 10 to realize the preset open state accordingly.

[0081] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated. In specific implementations, multiple features may be combined with each other as required and as technically feasible. Various substitutions, changes, and modifications may also be conceived without departing from the spirit and scope of the present invention.
