[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] In order to save space and make the placement of household appliances more compact, household appliances are stacked in many occasions, such as microwave ovens stacked on ovens, clothes dryers stacked on washing machines, small-sized washing machines stacked on normal-sized washing machines, etc. However, household appliances stacked in high places have the problem that the main control panel unit is too high and difficult to operate, and household appliances placed in low places have the problem that the main control panel unit is too low and needs to bend down to operate, and children are prone to misoperating the low-height main control panel unit, resulting in program changes of the running household appliances.

[0049] Based on the above problems, this embodiment provides a linkage control system for home appliances, including a control module 1 (see Figure 1 The control module 1 is separable from the plurality of household appliances and can be communicatively connected with the plurality of household appliances, so that the control module 1 can control any household appliance when it is separated from the plurality of household appliances.

[0050] Since the control module 1 can still communicate and connect with multiple household appliances when it is separated from them, the user can remove the control module 1 as needed, and control any household appliance by manipulating the control module 1 in the separated state. After the control is completed, the control module 1 can be placed in a position that is easy to take and can avoid being touched by children, so as to prevent children from misoperating the running household appliances. That is, whether it is a household appliance stacked high or placed low, it can be controlled by a control module 1 that can be separated from the household appliances, which can solve the problem that household appliances placed high are difficult to operate due to the high position of the main control board unit, and household appliances placed low need to bend down to operate due to the low position of the main control board unit and are easy to misoperate by children, thereby improving the degree of intelligence.

[0051] The plurality of household appliances include, but are not limited to, refrigerators, freezers, dishwashers, disinfection cabinets, electric ovens, electric steamers, microwave ovens, rice cookers, coffee machines, stoves, range hoods, washing machines, clothes dryers, electric water heaters, and stereos, etc.

[0052] Optionally, in this embodiment, if Figure 2As shown, the plurality of household appliances include a washing machine 3 and a dryer 4 stacked one above the other. The dryer 4 is stacked on the washing machine 3, and a stacking bracket 5 is provided between the two for fixing the upper dryer 4. The washing machine 3 and the dryer 4 share a main control board 31, which is provided on the washing machine 3, and the washing program and the drying program are integrated on the main control board 31. The control module 1 is connected to the main control board 31 in communication, and the control of the two appliances, the washing machine 3 and the dryer 4, is realized through the communication connection with the main control board 31. Since the main control board 31 is provided on the washing machine 3, the height of the display panel 311 on the main control board 31 is easier for the user to view, and compared with the main control board 31 provided on the dryer 4 at a high position, the scheme of providing the main control board 31 on the washing machine 3 is more convenient for the user to operate.

[0053] Of course, in other embodiments, the washing machine 3 and the dryer 4 may each be provided with a main control board 31 , and both main control boards 31 are communicatively connected to the detachable control module 1 .

[0054] Specifically, the control module 1 includes a control knob 11 and a connecting component arranged on the control knob 11. The control knob 11 is used to receive the user's twisting operation and control any household appliance according to the user's twisting operation. The connecting component is used to fix the control knob 11 in the storage area. The user can control the washing machine 3 and the dryer 4 by twisting the control knob 11, which is convenient to operate. Moreover, compared with arranging the program menu of the washing machine 3 and / or the dryer 4 on the control module 1 for pressing or touching control, the control knob 11 is small in size, light in weight, and has a better user experience. The storage area is used to store the control knob 11, which is convenient for users to take and prevent children from touching.

[0055] In some embodiments, the storage area includes a side wall of the household appliance, and the connecting component includes a magnetic member, which can be magnetically attracted to the side wall. Specifically, the side walls of the washing machine 3 and the clothes dryer 4 are made of a magnetically attracted metal material. After the control knob 11 is used, the magnetic member is magnetically attracted to the side wall of the washing machine 3 or the clothes dryer 4, so that the control knob 11 is fixed at a suitable height.

[0056] In other embodiments, Figure 3 As shown, the linkage control home appliance system further includes a knob bracket 2, which is configured to be installed at a user-specified point, and the connecting component includes a magnetic member, which is magnetically attracted to a storage area on the knob bracket 2. That is, the storage area is located on the knob bracket 2, and the user-specified point can be a wall in a bathroom or balcony, etc. The knob bracket 2 is installed at a suitable height position on the wall, so that it is convenient to take and put the control knob 11.

[0057] See also Figure 4The knob bracket 2 is provided with a mounting groove 21, and the control knob 11 is clamped in the mounting groove 21. That is, the mounting groove 21 is the above-mentioned storage area, and the control knob 11 is magnetically attracted to the mounting groove 21, so that the installation is more stable and the control knob 11 is prevented from falling off the knob bracket 2.

[0058] See also Figure 4 The knob bracket 2 is provided with a plurality of mounting holes 22, and the knob bracket 2 can be screwed to a user-specified point by passing screws through the mounting holes 22. Of course, the knob bracket 2 can also be fixed by other bonding, welding, etc.

[0059] Optionally, the magnetic member is a magnetic strip, a magnetic ring, a magnetic block or a magnetic sheet, etc.

[0060] In this embodiment, Figure 5 As shown, the control knob 11 includes a communication unit and a control unit. The communication unit is used to wirelessly communicate with multiple household appliances, and the control unit can send control instructions to any household appliance through the communication unit. Taking the stacked washing machine 3 and the dryer 4 as an example, if the washing machine 3 is controlled to execute the wool washing program, the control knob 11 is screwed. After being screwed in place, the control unit sends the wool washing control instruction to the washing machine 3 through the communication unit. After the main control board 31 on the washing machine 3 receives the instruction, it controls the washing machine 3 to execute the wool washing program.

[0061] See also Figure 1 and Figure 3 The control knob 11 includes a mounting body 111 and a rotating part 112. The rotating part 112 is rotatably arranged on the mounting body 111. When the rotating part 112 rotates relative to the mounting body 111, the control program of the household appliance is switched. Optionally, the mounting body 111 is cylindrical, and the rotating part 112 is rotatably sleeved outside the mounting body 111, and the twisting operation is more convenient. Exemplarily, when the rotating part 112 rotates relative to the mounting body 111, multiple washing programs of the washing machine 3 are switched one by one, such as a cotton and linen washing program, a wool washing program, a quick washing program, a baby clothes washing program, etc.; or multiple drying programs of the dryer 4 are switched, such as a quick drying program, a low-noise drying program, a cotton and linen drying program, a bedding drying program, etc.

[0062] In this embodiment, when the control program of the household appliance is switched, the display panel 311 on the household appliance displays the current control program. The user turns the rotating part 112 while observing the current control program displayed on the display panel 311 on the main control board 31. If the current control program is the program required by the user, it can be started. If it is not the program required by the user, the user continues to turn the switch until the program required by the user is displayed.

[0063] If the main control panel 31 is arranged on the washing machine 3, the user needs to bend down to check it. If the main control panel 31 is arranged on the clothes dryer 4 above, the user may not be able to see it or observe it.

[0064] In view of the above problems, in this embodiment, see Figure 1 and Figure 3 The mounting body 111 of the control knob 11 is provided with a display unit 113. When the control program of the household appliance is switched, the control unit controls the display unit 113 to display the current control program. The user only needs to turn the rotating part 112 while observing the display unit 113. When the control program displayed on the display unit 113 is the program required by the user, it can be executed, which makes the operation more convenient.

[0065] Optionally, the control knob 11 further includes an angle detection unit, which is used to detect the rotation angle of the rotating part 112 relative to the mounting body 111, and the control unit is also used to switch the control program displayed on the display unit 113 according to the rotation angle. When the rotating part 112 rotates relative to the mounting body 111 by a preset angle N, the current control program switches to the next control program, and the preset angle N is selected according to design requirements. Exemplarily, the multiple programs set in sequence are a cotton and linen washing program, a wool washing program, a baby clothes washing program, a bedding washing program, and a quick washing program. The current control program displayed on the display unit 113 is a cotton and linen washing program. If the rotating part 112 rotates relative to the mounting body 111 by a preset angle N, the control unit controls the display unit 113 to display the wool washing program. If the rotating part 112 continues to rotate by 2N angles, the control unit controls the display unit 113 to display the bedding washing program.

[0066] Exemplarily, the angle detection module is an encoder, and the control unit can obtain the rotation angle of the encoder to control the display unit 113.

[0067] Optionally, the display unit 113 includes a touch screen, which is used to receive the user's switching operation instructions, and the control unit is also used to switch different household appliances for control according to the switching operation instructions. For example, the current control knob 11 can control the washing machine 3, and when the rotating part 112 is turned, the displayed programs are all washing programs. When the user issues a switching operation instruction of "switch to the dryer 4" through the touch screen, the control unit switches to the dryer 4 for control according to the instruction, and when the rotating part 112 is turned, the displayed programs are all drying programs.

[0068] The schemes for issuing the switching operation instruction through the touch display screen include lightly touching the touch display screen three times, long pressing the touch display screen for m seconds (for example, 3 seconds), etc.

[0069] Furthermore, an indicator light may be provided to remind the user of the currently controlled household appliance. For example, if the indicator light is yellow, the washing machine 3 is under control, and if it is blue, the drying machine 4 is under control.

[0070] Specifically, an embodiment is provided below to describe the display mode of the touch display screen. The touch display screen has a color screen mode and an energy-saving mode.

[0071] like Figure 6 and Figure 7 As shown, when the touch screen is in color screen mode, the touch screen has a prompt halo 1131 and a first prompt light 1132. The current control program and the start / stop operation key are displayed on the inner side of the prompt halo 1131 on the touch screen. The current control program can be started or temporarily stopped by touching the start / stop operation key. The first prompt light 1132 is located on the outer side of the prompt halo 1131. The area where the first prompt light 1132 is located is used to receive the user's switching operation instructions. The prompt halo 1131 and the first prompt light 1132 display different colors when switching to different household appliances.

[0072] Specifically, after the control knob 11 is separated from the washing machine or the dryer, remote startup and remote control can be achieved. The rotating portion 112 is located on the outer ring of the touch screen. By lightly touching the area where the first prompt light 1132 is located several times (for example, three times) or pressing for a few seconds (such as 3 seconds), the washing mode and the drying mode can be switched. When switching to the washing machine mode, the prompt halo 1131 and the first prompt light 1132 are both yellow. When the rotating portion 112 is rotated, the control program is switched, and the pattern of the control program is displayed on the inside of the prompt halo 1131. After rotating to the desired control program, touch the control program so that the start and stop operation keys are displayed on the inside of the prompt halo 1131, such as Figure 7 Touch the start / stop button to start the currently selected control program. To pause the control program, touch the start / stop button again.

[0073] like Figure 8 As shown, when the touch display screen is in energy-saving mode, the touch display screen has a central aperture 1133 and a second indicator light 1134. The area where the central aperture 1133 is located is used to receive the user's switching operation instructions, and to prompt with different light signals when switching to different household appliances. The second indicator light 1134 changes from flashing to constantly on after the program selection is completed.

[0074] Specifically, the touch screen in energy-saving mode displays black and white as a whole, which saves more electricity than the color screen mode. By tapping the area where the central aperture 1133 is located several times (for example, three times) or pressing for a few seconds (such as 3 seconds), the washing mode and the drying mode can be switched. When switching the washing / drying mode, the light signal of the central aperture 1133 changes. For example, in the washing mode, the central aperture 1133 lights up white, and in the drying mode, the central aperture 1133 lights up yellow. At this time, in order to save power, the touch screen no longer displays the current control program, but displays the current control program through the display panel 311 on the main control board. After the required program is selected, the second indicator light 1134 changes from strobing to constantly on. After that, the program starts.

[0075] Optionally, the control unit can control the communication unit to disconnect from the current household appliance according to the switching operation instruction, and match and connect with another household appliance to achieve switching control of the household appliance.

[0076] In other embodiments, the control knob 11 also includes a button, which is used to accept a user's pressing operation to execute a power-on command, a power-off command, a start command, and a pause command on the household appliance. For example, the button is set at the center of the mounting body 111, and the display unit 113 is set around the button. By operating the button, a power-on command, a power-off command, a start command, and a pause command can be sent to the household appliance. Exemplarily, a long press of the button sends a power-on command, and the control unit controls the corresponding household appliance to start up through the communication unit according to this command. Long pressing the button again sends a power-off command. After starting up, after selecting the current control program through the control knob 11, a short press of the button sends a start command so that the corresponding household appliance runs the current control program. During operation, the button can be short-pressed again to pause the program.

[0077] In some embodiments, the control knob 11 includes a power source 1115 (see Fig. 9 ) and a charging unit, the power supply 1115 is used to supply power to the control knob 11, so that the knob still has power when it is separated from the household appliance to achieve control. The charging unit is used to charge the power supply 1115 so that the control knob 11 has sufficient power.

[0078] In this embodiment, the communication connection method between the control knob 11 and the washing machine 3 and the dryer 4 is not limited to wireless connection such as Bluetooth / Matter / Wi-Fi. Within the controllable range, the user can select the washing / drying program through the control knob 11.

[0079] In order to realize the control knob 11 to control the washing machine 3 and the drying machine 4, the following scheme is provided for illustration.

[0080] like Fig. 9As shown, the communication unit of the control knob 11 includes a Bluetooth module 1112, and the control unit includes a knob processor 1111. A cavity is provided on the mounting body of the control knob 11, and the Bluetooth module 1112, the knob processor 1111 and the above-mentioned power supply 1115 are all provided in the cavity. A magnetic field driving module 1113 and a magnetic field sensing module 1114 are also provided in the cavity. Among them, the power supply 1115 supplies power to the Bluetooth module 1112, the knob processor 1111, the magnetic field driving module 1113 and the magnetic field sensing module 1114, etc. The knob processor 1111 is connected to the magnetic field driving module 1113, and the knob processor 1111 controls the magnetic field driving module 1113 to generate a high-frequency excitation magnetic field; the magnetic field sensing module 1114 is connected to the knob processor 1111, and when the magnetic field sensing module 1114 senses that the high-frequency excitation magnetic field has changed, an induction signal is generated, and the induction signal is sent to the knob processor 1111.

[0081] The knob processor 1111 is connected to the washing machine 3 / dryer 4 via the Bluetooth module 1112. The knob processor 1111 receives the sensing signal to generate a washing / drying control signal and sends the program control signal to the washing machine 3 / dryer 4.

[0082] The washing machine 3 / drying machine 4 is provided with a Hall sensor inside, and the Hall sensor is provided in the main control board. The rotating part of the control knob 11 is connected to the magnetic field sensing module 1114. The Hall sensor is used to determine whether the magnetic field of the control knob 11 changes, and if so, the program control signal sent by the control knob 11 is received.

[0083] When receiving the control signal, the main control board analyzes the control signal and obtains the signal identifier; determines whether the signal identifier is consistent with the signal identifier of the control knob 11. If so, the dryer 4 / washing machine 3 is started to ensure that it is controlled by the control knob 11.

[0084] In the above scheme, the rotating part 112 of the control knob 11 receives the user's control command, senses the magnetic field change according to the control command, and generates a magnetic field sensing signal; analyzes the magnetic field sensing signal to obtain a washing / drying control signal; and sends the washing / drying signal to the washing machine 3 / dryer 4, thereby realizing the control of the washing machine 3 / dryer 4 through the program control knob.
