Description

Water supply appliance and control device thereof

Technical Field

The present invention relates to knob control technology, and is especially one kind of water supply appliance and its control device.

Background

One control device for existing smart water supplies, such as electronic showers, includes a knob and incremental rotary encoder. The knob is sleeved on the main shaft of the incremental rotary encoder. The incremental rotary encoder has a key function. Turning the knob in one direction, the incremental rotary encoder outputting a first control signal; the knob is turned to the other direction, and the incremental rotary encoder can output a second control signal; the incremental rotary encoder can output a third control signal by pressing the knob in a direction adjacent to the incremental rotary encoder. Thus, the intelligent water feeder can be controlled by the control device through sending three control commands.

The body of the incremental rotary encoder is arranged on the inner side of the panel for water isolation, the main shaft of the incremental rotary encoder needs to penetrate through the panel to be fixedly connected with the knob on the outer side of the panel, water on the outer side of the panel can enter the body of the incremental rotary encoder along the main shaft, and therefore the waterproof performance of the control device is poor. Meanwhile, because the main shaft is fixedly connected with the knob, a gap between the knob and the panel is small, the gap is difficult to clean, and dirt are easy to store.

In the other existing control device, a magnetic control knob is used for control, but the existing magnetic control knob can only transmit instructions through rotation. For example, a first type of command is sent for clockwise rotation and a second type of command is sent for counterclockwise rotation. This control device cannot issue the third command by pressing the knob as in the previous control device.

The frame body 381 overlaps the edge of the gasket 37.

The frame 381 and the frame 34 can be connected by screws, and the frame 381 and the frame 34 clamp the edge of the sealing gasket 37 so that water cannot enter the frame 34 from the top of the frame 34 to short circuit the circuit on the first circuit board 35, thereby further improving the sealing performance of the control knob 3.

In one exemplary embodiment, as shown in fig. 3 and 4, the gasket 37 includes a gasket body 371 and a male cap 372. The gasket body 371 is the main body structure of the gasket 37, and may be a substantially sheet-like structure.

The key switch 36 is disposed between the convex cap 372 and the first circuit board 35, and the key of the key switch 36 is inserted into the convex cap 372.

The push switch 36 is partially inserted into the convex cap 372, so that the control knob 3 is more compact, and the thickness of the control knob 3 can be reduced. The thickness with the top of protruding cap 372 sets up thickly, reduces the stroke that top shell 31 moved down, and top shell 31 moves down shorter distance just can press key switch 36's button, and deformation takes place at the top of protruding cap 372 when can avoiding top shell 31 to push down protruding cap 372 simultaneously, and the pressure energy that top shell 31 applyed can transmit on the button steadily.

One end of the elastic portion 382 away from the frame 381 may abut against the top plate 311. The elastic portion 382 can be elastically deformed.

When the top case 31 is pressed, the elastic portion 382 is compressed to apply an elastic force to the top case 31 in a direction away from the bottom case 32 after the top case 31 and the bottom case 32 slide toward each other. After releasing the top shell 31, the top shell 31 can move back to the original position in the direction away from the bottom shell 32 under the action of the elastic force.

In an exemplary embodiment, the elastic portion 382 is provided in plurality. The plurality of elastic portions 382 are uniformly distributed along the inner circumferential surface of the frame 381. The plurality of elastic portions 382 have the same spiral direction.

The elastic portions 382 can simultaneously apply an elastic force to the top plate 311, and the elastic force applied to the top plate 311 is more uniformly distributed on the top plate 311, so that the relative sliding between the bottom case 32 and the top case 31 can be smoother.

In an exemplary embodiment, the top case 31 further includes a stopper portion 313. The stopper portion 313 is provided on an inner wall of the side plate 312, that is, on an inner side wall of the top case 31. The edge of the frame 34 is located between the stopper portion 313 and the top plate 311.

When the frame 34 moves in a direction away from the top plate 311, the frame 34 abuts against the stopper 313, and the edge of the frame 34 cannot be removed from the top case 31 by the stopper 313, so that the stopper 313 prevents the top case 31 and the bottom case 32 from being separated from each other.

In an exemplary embodiment, the base plate 33 further includes a third mount 334. The third mount 334 may be cylindrical, for example.

The two poles of the third magnet 42 may be located at opposite ends of the third magnet 42, respectively. The third magnet 42 is disposed within the third mount 334. The third magnet 42 and the third mount 334 may be coaxially disposed. The third mount 334 and the third magnet 42 may be an interference fit.

The receiver 2 further comprises a plurality of hall sensors 23. The plurality of hall sensors 23 are electrically connected to the control circuit 14. The plurality of hall sensors 23 are each provided on the substrate 211. The distance between each hall sensor 23 and the second magnet 22 is equal. The distance between the hall sensor 23 and the second magnet 22 is substantially the same as the distance between the third magnet 42 and the first magnet 39.

When the first magnet 39 and the second magnet 22 are attracted to each other, the third magnet 42 can rotate around the second magnet 22 by rotating the control knob 3, and the third magnet 42 has a circular moving path. When the control knob 3 is attached to the receiver 2, the plurality of hall sensors 23 are all close to the movement path of the third magnet 42 and are arranged in sequence along the movement path, so that the plurality of third magnets 23 are arranged in sequence along the same movement direction. The hall sensor 23 can detect the change of the magnetic field, and the hall sensor 23 is activated when the third magnet 42 approaches the hall sensor 23. Thus, the third magnet 42 can sequentially activate the hall sensors 23 sequentially arranged along the moving path thereof after being rotated.

The hall sensor 23 is configured to send a trigger signal to the control circuit 14 upon sensing the approach of the third magnet 42. The control circuit 14 may be connected to the hall sensors 23 through a plurality of lines. The control circuit 14, upon receiving the trigger signal, can determine the source of the trigger signal and obtain information that the hall sensor 23 has been triggered.

The control circuit 14 is configured to generate corresponding control instructions according to the sequence in which the plurality of hall sensors 23 are triggered.

In the present embodiment, the control circuit 14 is configured to send a third control instruction to the main system circuit 101 when the hall sensors 23 in the first controller 11 are sequentially activated in one direction of the movement path of the third magnet 42, and send a fourth control instruction to the main system circuit 101 when the hall sensors 23 in the second controller 12 are sequentially activated in the other direction of the movement path of the third magnet 42. The third control instruction may be for instructing to increase the set outlet water temperature, and the fourth control instruction may be for instructing to decrease the set outlet water temperature.

Thus, the control circuit 14 can transmit the third control command to the main system circuit 101 when the control knob 3 of the first controller 11 is rotated in one direction, and the control circuit 14 can transmit the fourth control command to the main system circuit 101 when the control knob 3 of the first controller 11 is rotated in the other direction.

The control circuit 14 is also configured to send a fifth control instruction to the main system circuit 101 when the hall sensors 23 in the second controller 12 are sequentially activated in one direction of the movement path of the third magnet 42, and to send a sixth control instruction to the main system circuit 101 when the hall sensors 23 in the second controller 12 are sequentially activated in the other direction of the movement path of the third magnet 42. The fifth control instruction may be for instructing to increase the set outlet water flow rate, and the sixth control instruction may be for instructing to decrease the set outlet water flow rate.

Thus, the control circuit 14 can transmit the fifth control command to the main system circuit 101 when the control knob 3 of the second controller 12 is rotated in one direction, and the control circuit 14 can transmit the sixth control command to the main system circuit 101 when the control knob 3 of the first controller 11 is rotated in the other direction.

In one exemplary embodiment, the third magnet 42 may be provided in plurality. The plurality of third magnets 42 are spaced apart from each other. The distances from the plurality of third magnets 42 to the first magnet 39 are all equal. Thus, the plurality of third magnets 42 all move along the same movement path and in the same direction when the control knob 3 is rotated.

The plurality of third magnets 42 are widely distributed in the movement path thereof, and the possibility that at least one hall sensor 23 is activated is higher, so that the sensitivity of recognizing the rotation of the control knob 3 can be improved.

In an exemplary embodiment, as shown in fig. 7, the number of the hall sensors 23 is n, n is an integer greater than or equal to 2, and an angle between the centers of two adjacent hall sensors 23 and a line connecting the centers of the second magnets 22 is m degrees, where m is 180 ÷ n.

In the present embodiment, the number of the hall sensors 23 may be 4, and the distances between two adjacent hall sensors 23 are equal. The angle between the connecting lines of the centers of two adjacent hall sensors 23 and the center of the second magnet 22 is 45 °.

The plurality of third magnets 42 are divided into two groups, and the two groups of third magnets 42 are symmetrically disposed on opposite sides of the first magnet 39. As shown in fig. 4 and 5, the number of the third magnets 42 is 4, and the 4 third magnets 42 are divided into two groups, and the two groups of the third magnets 42 are symmetrically arranged on two opposite sides of the first magnet 39.

After the arrangement, when the control knob 3 is adsorbed to the receiver 2, at least one hall sensor 23 is triggered, and simultaneously, one hall sensor 23 can be triggered every time the control knob 3 rotates m degrees. The number of the third magnets 42 and the number of the hall sensors 23 are both set to be small, the weight of the control knob 3 can be reduced by the small number of the third magnets 42, and the symmetrical distribution of the third magnets 42 can make the control knob 3 smooth when rotating.

In an exemplary embodiment, each set of the third magnets 42 has at least 2 third magnets 42, and an angle between a line connecting centers of two adjacent third magnets 42 in the same set of the third magnets 42 with the center of the first magnet 39 is equal to an angle between a line connecting centers of two adjacent hall sensors 23 with centers of the second magnet 22.

In the present embodiment, the number of the third magnets 42 in each set of the third magnets is two, and the angle between the connecting lines of the centers of the two third magnets 42 in each set of the third magnets 42 and the center of the first magnet 39 is 45 °.

In an exemplary embodiment, the main system circuit 101 is configured to enter a sleep mode after being powered on, and enter a parameter setting mode after receiving a first control instruction or a second control instruction while in the sleep mode.

When the main system circuit 101 is in the sleep mode, the first controller 11 sends a first control instruction to the main system circuit 101 after the control knob 3 of the first controller 11 is pressed, or the second controller 12 sends a second control instruction to the main system circuit 101 after the control knob 3 of the second controller 12 is pressed, and the main system circuit 101 is awakened from the sleep mode to the parameter setting mode.

The main system circuit 101 is further configured to switch a water outlet mode as a set water outlet mode when receiving a first control instruction in the parameter setting mode, and drive the display screen 105 to display the current set water outlet mode.

The number of water outlet patterns may be the same as the number of water outlets. The water outlet modes correspond to the water outlets one by one. Each water outlet mode is set to be water outlet corresponding to the water outlet. For example, 3 water outlets on the valve body are respectively connected with the shower head, the top shower and the water outlet pipe, and the three water outlets can respectively correspond to a shower head water outlet mode, a top water spraying mode and a water outlet pipe water outlet mode. In the parameter setting mode, the water outlet mode is switched once when the control knob 3 of the first controller 11 is pressed once, and the set water outlet mode is displayed on the display screen 105 after being changed every time. For example, the default setting water outlet mode is the shower water outlet mode, and the shower water outlet mode is displayed on the display screen 105; after the control knob 3 of the first controller 11 is pressed for the first time, the set water outlet mode is changed into a top water spraying mode, and at the moment, the top water spraying mode is displayed on the display screen 105; after the control knob 3 of the first controller 11 is pressed for the second time, the water outlet mode is set to be changed into water outlet of the water outlet pipe, and at the moment, the water outlet of the water outlet pipe is displayed on the display screen 105; after the control knob 3 of the first controller 11 is pressed for the third time, the set water outlet mode is changed to the shower water outlet mode, and at this time, the shower water outlet mode is displayed on the display screen 105.

The main system circuit 101 is further configured to, in the parameter setting mode, increase the set outlet water temperature upon receiving a third control command, and drive the display screen 105 to display the current set outlet water temperature.

The set water outlet temperature is the water temperature of water to be discharged from the water outlet corresponding to the set water outlet mode. The default set outlet water temperature in the main system circuit 101 may be 37 ℃ or 38 ℃, or may be the set outlet water temperature set when the water supply device 100 was last used. Rotating the control knob 3 of the first controller 11 in one direction, for example, rotating the control knob 3 in a clockwise direction, the first controller 11 sends a third control instruction to the main system circuit 101 every time the control knob 3 rotates by a preset angle, which may be 45 °. The main system circuit 101 increases the set water temperature once every time it receives the third control instruction, the increasing amplitude of each time is a first preset amplitude, and the value range of the first preset amplitude can be 0.5-1 ℃. After the set outlet water temperature is changed every time, the main system circuit 101 drives the display screen 105 to display the changed set outlet water temperature.

The main system circuit 101 is further configured to, in the parameter setting mode, lower the set outlet water temperature upon receiving a fourth control instruction, and drive the display screen 105 to display the current set outlet water temperature;

rotating the control knob 3 of the first controller 11 in another direction, for example, rotating the control knob 3 in a counterclockwise direction, the first controller 11 sends a fourth control command to the main system circuit 101 every time the control knob 3 rotates by a preset angle, which may be 45 °. The main system circuit 101 decreases the set water temperature once every time it receives the fourth control instruction, the decreasing amplitude is a second preset amplitude, and the value range of the second preset amplitude may be 0.5-1 ℃. After the set outlet water temperature is changed every time, the main system circuit 101 drives the display screen 105 to display the changed set outlet water temperature.

The main system circuit 101 is further configured to increase the set water outlet flow rate and drive the display screen 105 to display the set water outlet flow rate when receiving a fifth control instruction in the parameter setting mode;

the set water outlet flow is the water flow to be discharged from the water outlet corresponding to the set water outlet mode. The default drain flow rate in the main system circuit 101 may be a set outlet flow rate set when the water supply device 100 was last used, or may be a preset value. Rotating the control knob 3 of the second controller 12 in one direction, for example, rotating the control knob 3 in a clockwise direction, the second controller 12 sends a fifth control command to the main system circuit 101 every time the control knob 3 rotates by a preset angle, which may be 45 °. The main system circuit 101 increases the set water outlet flow once every time it receives the fifth control instruction, the increased amplitude of each time is a third preset amplitude, and the value range of the third preset amplitude can be 0.05-0.5 m³And/min. After the set outlet flow is changed every time, the main system circuit 101 drives the display screen 105 to display the changed set outlet flow.

The main system circuit 101 is further configured to turn down the set water flow rate and drive the display screen 105 to display the set water flow rate when receiving the sixth control command in the parameter setting mode.

Rotating the control knob 3 of the second controller 12 in the other direction, for example, rotating the control knob 3 in the counterclockwise direction, the second controller 12 sends a sixth control command to the main system circuit 101 every time the control knob 3 rotates by a preset angle, which may be 45 °. The main system circuit 101 increases the set water outlet flow once every time it receives the fifth control instruction, the increased amplitude of each time is a third preset amplitude, and the value range of the third preset amplitude can be 0.05-0.5 m³And/min. After the set outlet flow is changed every time, the main system circuit 101 drives the display screen 105 to display the changed set outlet flow.

The main system circuit 101 is further configured to receive a second control command to control the water outlet mode, the set water outlet temperature, and the set water outlet flow rate to control the water outlet of the water supply device 100 in the parameter setting mode.

When the main system circuit 101 is in the parameter setting mode, the second controller 12 sends a second control instruction to the main system circuit 101 after the control knob 3 of the second controller 12 is pressed, and the main system circuit 101 determines to control the water outlet of the water supply device 100 according to the set water outlet mode, the set water outlet temperature and the set water outlet flow.

In the present embodiment, the main system circuit 101 controls the outlet water temperature by driving the thermostatic cartridge 102 so that the outlet water temperature is maintained at the set outlet water temperature.

The main system circuit 101 also controls the flow rate of the outlet water by driving the flow control valve 102 so that the flow rate of the outlet water is maintained at the set flow rate of the outlet water.

The main system circuit 101 also opens by driving only the solenoid valve 104 corresponding to the set water outlet mode, so that the water outlet corresponding to the set water outlet mode is drained.
