Description

Electronic shower and control method thereof

Technical Field

The invention relates to a valve technology, in particular to an electronic shower and a control method thereof.

Background

Electronic showers on the market are more and more in variety, and the electronic shower has the advantages of multiple functions, simplicity and convenience in operation, strong technological sense, good experience effect and the like. The electronic shower is used for controlling the on-off of a water path in the shower set.

Existing electronic showers typically include a control panel and a plurality of solenoid valves. Each solenoid valve controls the on-off of one water path in the shower set. The electromagnetic valve is electrically connected with the control panel. The control panel is provided with a plurality of keys, the keys and the electromagnetic valves are arranged in a one-to-one correspondence manner, and each key controls the opening and closing of the corresponding electromagnetic valve. The electronic shower has too many electromagnetic valves, and the electromagnetic valves are easy to damage in the using process, so that the overall reliability of the electronic shower is low.

The existing keys on the control panel are usually touch keys. In practical use, the touch key is easily touched by mistake, for example, the touch key is easily triggered when water drops sprayed on a shower head or a top shower are splashed on the touch key during bathing, so that misoperation of the electronic shower is caused.

Since the line from the water heater to the electronic shower is filled with cold water, the cold water needs to be drained through the electronic shower to allow hot water to drain from the electronic shower while showering. Therefore, when the user opens the electronic shower to take a shower, the user usually needs to stand by or the like to discharge cold water, which affects the shower experience. In particular, after discharging the cold water, the user may not yet be aware that the cold water has been discharged, resulting in that the hot water of a proper temperature continues to be directly discharged, wasting a large amount of hot water.

Disclosure of Invention

This kind of electronic shower includes:

a valve body;

a control panel including a control circuit;

the electromagnetic valve is electrically connected with the control circuit, is arranged on the valve body and is used for opening and closing the water outlet of the valve body;

the temperature sensor is electrically connected with the control circuit, is arranged on the valve body and is used for measuring the water temperature of the water discharged from the valve body;

wherein the control circuit is configured to:

after receiving a pre-discharge cold water trigger signal, driving the electromagnetic valve to open so that the valve body discharges water;

Detailed Description

As shown in fig. 1, fig. 1 shows a shower set according to the present embodiment. The shower set includes an electronic shower 1, a shower head 71 and a top shower 72. Both the shower head 71 and the top shower 72 are communicated with the electronic shower 1 through pipelines.

As shown in fig. 2, the electronic shower 1 includes a valve body 4, a temperature sensor 91, a solenoid valve 53, a protective case 3, and a control panel 2. The solenoid valve 53 and the temperature sensor 91 are both mounted on the valve body 4. The valve body 4, the temperature sensor 91, and the solenoid valve 53 are all disposed inside the protective case 3. The control panel 2 is installed outside the protective case 3. The control panel 2 is electrically connected to the solenoid valve 53, and the control panel 2 can control the opening and closing of the solenoid valve 53.

The valve body 4 includes a mixing passage 430, and the mixing passage 430 is provided inside the valve body 4. The mixing channel 430 is a main channel of the water channel in the valve body 4, and water discharged outside the electronic shower 1 needs to pass through the mixing channel 430. The solenoid valve 53 is provided on the mixing passage 430. The solenoid valve 53 divides the mixing passage 430 into a first mixing flow path 433 and a second mixing flow path 434. The second mixed water flow path 434 is located at the upstream of the first mixed water flow path 433, and the externally inputted cold water and the externally inputted hot water are mixed according to a predetermined ratio and then injected into the first mixed water flow path 433. When the solenoid valve 4 is opened, the mixing channel 430 is turned on, so that water can be delivered from the first mixing flow channel 433 to the second mixing flow channel 434, and finally discharged out of the valve body 4, and the valve body 4 discharges water outwards. When the solenoid valve 4 is closed, the mixing passage 430 is blocked, and the valve body 4 stops the water from being discharged to the outside. Therefore, the solenoid valve 4 can open and close the water outlet of the valve body 4.

A temperature sensor 91 is mounted on the valve body 4, and the temperature sensor 91 may be disposed in the second mixed water flow passage 434. The temperature sensor 91 is used to measure the temperature of the water discharged from the electronic shower 1.

The control panel 2 includes a circuit board 23. As shown in fig. 5 and 6, the circuit board 23 is provided with a first key switch 231, a second key switch 232, and a control circuit 235. The circuit board 23 may be a rectangular flat plate. The first key switch 231 and the second key switch 232 are both disposed on the same panel of the circuit board 23. The control circuit 235 may be provided on the other board surface of the circuit board 23.

The first and second

key switches

231 and 232 may be a touch key switch. The first key switch 231, the second key switch 232, the temperature sensor 91 and the solenoid valve 53 are electrically connected to the control circuit 235. The temperature sensor 91 transmits the measured temperature data to the control circuit 235 in real time.

The first push switch 231 can activate the pre-cooling water of the electronic shower 1. When the first key switch 231 is activated, it sends a pre-chilled water trigger signal to the control circuit 235.

The control circuit 235 is configured to drive the solenoid valve 53 to open to allow the valve body 4 to discharge water after receiving the pre-discharge cold water trigger signal, and drive the solenoid valve 53 to close to allow the valve body 4 to stop discharging water when any one of the stop conditions is satisfied. The first stop condition is that the temperature measured by the temperature sensor 91 exceeds a first preset temperature. The first preset temperature is greater than or equal to 36 ℃ and less than or equal to 40 ℃. The first preset temperature may be 38 ℃.

Thus, when the user uses the electronic shower 1, the user may press the first key switch 231, the first key switch 231 sends the pre-cooling water discharge trigger signal to the control circuit 235, and the control circuit 235 opens the electromagnetic valve 53 to discharge water from the valve body 4 after receiving the pre-cooling water discharge trigger signal. Then, the control circuit 235 determines whether the temperature of the outward water discharged from the valve body 4 detected by the temperature sensor 91 reaches a first preset temperature, and when the temperature of the outward water discharged from the valve body 4 detected by the temperature sensor 91 reaches the first preset temperature, the control circuit 235 closes the electromagnetic valve 53 to stop the outward water discharge of the electronic shower 1. Therefore, the user does not need to wait at one side during the cold water pre-discharging period, and waste caused by excessive hot water being directly discharged can be avoided.

In one exemplary embodiment, the second stop condition is that the opening time of the solenoid valve 53 reaches a first preset time period. The value range of the first preset time is greater than or equal to 50s and less than or equal to 70 s. The first preset duration is preferably 60 s.

After the control circuit 235 receives the pre-discharge cold water trigger signal, the electromagnetic valve 53 is opened, a first timing unit in the control circuit 235 starts timing, and when the time length measured by the first timing unit reaches a first preset time length, the control circuit 235 drives the electromagnetic valve 53 to close.

When no hot water exists in the electric water heater or the gas water heater is not ignited, the temperature of the water input into the valve body 4 by the water heater is too low to trigger the closing condition of the electromagnetic valve 53, at the moment, if the opening time of the electromagnetic valve 53 reaches a first preset time length, the electromagnetic valve 53 is automatically closed, and the situation that the electromagnetic valve 53 is not closed to cause the valve body 4 to always output water is avoided.

In an exemplary embodiment, the third stopping condition is that the temperature sensor 91 measures the first temperature value when the opening time of the solenoid valve 53 reaches the second predetermined time period, the temperature sensor 91 measures a second temperature value that maintains the third predetermined time period after the first temperature value is measured, the difference between the second temperature value and the first temperature value is greater than or equal to the predetermined temperature difference, and the second temperature value is greater than or equal to the second predetermined temperature.

The value range of the second preset time is greater than or equal to 2s and less than or equal to 4 s. The value range of the third preset time length is greater than or equal to 4s and less than or equal to 6 s. The value range of the preset temperature difference is more than 4 ℃ and less than or equal to 6 ℃. The second preset temperature is greater than or equal to 31 ℃ and less than or equal to 35 ℃.

After the control circuit 235 receives the pre-discharge cold water trigger signal, the solenoid valve 53 is opened, and the first timing unit in the control circuit 235 starts timing. When the time measured by the first timing unit reaches a second preset time, which is 3s for example, the control circuit 235 records the first temperature value measured by the temperature sensor 91 at this time.

While recording the first temperature value, a second timing unit in the control circuit 235 starts timing, and triggers the second timing unit to restart timing when the temperature value measured by the temperature sensor 91 changes. When the time measured by the second timing unit reaches a third preset time, which is 5s, for example, the control circuit 235 records the temperature value as the second temperature value. When the second temperature value is obtained, the temperature of the outlet water of the valve body 4 is kept at the second temperature value for a third preset time.

The control circuit 235 determines whether the difference between the second temperature value and the first temperature value is greater than or equal to a predetermined temperature difference, and whether the first temperature value is greater than or equal to a second predetermined temperature. The preset temperature difference may be 5 deg.c and the second preset temperature may be 33 deg.c.

If the difference between the second temperature value and the first temperature value is greater than or equal to the preset temperature difference, and the second temperature value is greater than the second preset temperature, the control circuit 235 drives the electromagnetic valve 53 to close.

If the difference between the second temperature value and the first temperature value is less than the preset temperature difference, or the first temperature value is less than or equal to the second preset temperature, the control circuit 235 re-acquires the second temperature value that can be kept unchanged within a third preset time period through the temperature sensor 91 until the acquired second temperature value satisfies that the difference between the second temperature value and the first temperature value is greater than or equal to the preset temperature difference, and the second temperature value is greater than the second preset temperature.

When the electronic shower 1 is used, the electronic shower 1 can discharge water at a set temperature after cold water is drained. The set temperature can be adjusted. The first preset temperature of the electronic shower 1 may be equal to or slightly lower than the maximum value of the set temperature of the electronic shower. The second preset temperature of the electronic shower 1 may be equal to the lowest value of the set temperature of the electronic shower 1. When the set temperature is adjusted to be greater than or equal to a first preset temperature, the electronic shower 1 stops draining water because a first stop condition is met during cold water pre-draining; when the set temperature is adjusted to be less than the first preset temperature and greater than or equal to the second preset temperature, the electronic shower stops draining because the third stopping condition is met.

In an exemplary embodiment, the fourth stop condition is that the solenoid valve 53 receives the pre-discharge cold water trigger signal again in the open state.

The control circuit 235 is further configured to determine whether the solenoid valve 53 is in an open state after each receipt of the pre-chill water trigger signal. If the solenoid valve 53 is in the closed state, the control circuit 235 drives the solenoid valve 53 to open; if the solenoid valve 53 is in the closed state, the control circuit drives the solenoid valve 53 to close.

The pre-chilled water discharge may be activated when the first key switch 231 is pressed for the first time. The first key switch 231 is pressed again before the pre-discharge of the cold water is finished, that is, the first key switch 231 is pressed again when the electromagnetic valve is still in an open state, the first key switch sends a pre-discharge cold water trigger signal to the control circuit 235, and the control circuit 235 drives the electromagnetic valve 53 to close after receiving the pre-discharge cold water trigger signal. Thus, the pre-discharge of cold water can be manually stopped in advance.

In an exemplary embodiment, the second push switch 232 is used to control the regular water outlet of the electronic shower 1. The second key switch 232 sends a normal water-out trigger signal to the control circuit 235 after being triggered.

The control circuit 235 is configured to maintain the solenoid valve 53 in an open state after receiving the normal water-out trigger signal until the solenoid valve 53 is closed after receiving the next normal water-out trigger signal.

After the second key switch 232 is pressed for one time, the second key switch 232 sends a conventional water outlet trigger signal to the control circuit 235, and the control circuit 235 opens the electromagnetic valve 53 and keeps the electromagnetic valve 53 in an open state after receiving the conventional water outlet trigger signal. After the second key switch 232 is pressed again, the control circuit 235 receives the normal water outlet trigger signal again, and drives the electromagnetic valve 53 to close. The user can control the normal drainage of the electronic shower 1 through the second key switch 232 while taking a shower.

In an exemplary embodiment, a display device 233 is also disposed on the circuit board 23. The display device 233 may be a nixie tube, such as an LED nixie tube. The display device 233 is used to display the temperature of the water discharged to the outside of the electronic shower 1 in real time. The temperature sensor 91 sends the temperature data of the water discharged from the valve body 4 to the control circuit 235 in real time, and the control circuit 235 is configured to drive the display device 233 to display the temperature of the water discharged from the valve body 4 to the water in real time after receiving the temperature data.

In one exemplary embodiment, as shown in fig. 2 and 3, the protective case 3 includes a main housing 31 and a flap 6. The main housing 31 is configured in a box shape. An internal cavity 30 is provided in the main housing 31. An opening 321 is formed at one side of the main housing 31, and the opening 321 is communicated with the inner cavity 30. The valve body 4 is disposed in the internal cavity 30 of the main housing 31. The valve body 4 is connected with the main shell 31, and the valve body 4 can be connected with the main shell 31 through screws. The solenoid valve 53 is inserted through the opening 321.

In the present embodiment, the main casing 31 includes a top plate 36, a bottom plate 37, a first side plate 34, a second side plate 35, a front plate, and a rear plate. The top plate 36, bottom plate 37 and rear plate are rectangular flat plates. The front plate is a strip-shaped plate. The top plate 36, bottom plate 37 and back plate are preferably rectangular flat plates. The bottom plate 37 is disposed below the top plate 36. The top plate 36 may be horizontally disposed. The four sides of the top plate 36 are vertically aligned with the four sides of the bottom plate 37, respectively. The first side panel 34, the second side panel 35, the front panel and the rear panel are each disposed between the top panel 36 and the bottom panel 37. The upper and lower ends of the back plate abut the top and

bottom plates

36 and 37, respectively. The rear panel may be in abutment with one long side of the top panel 36 and the bottom panel 37 adjacent to each other. The upper and lower ends of the front plate abut the top and

bottom plates

36 and 37, respectively. The front panel may abut the other long side where the top panel 36 and the bottom panel 37 approach each other. The side edges of the first side plate 34 and the second side plate 35 are located at opposite ends of the front plate, respectively. The first side plate 34 and the second side plate 35 each abut against the top plate 36, the bottom plate 37, the front plate 31 and the rear plate 33. Thus, the top plate 36, the bottom plate 37, the first side plate 34, the second side plate 35, the front plate 31, and the rear plate 33 enclose the main casing 31 of a box type. The opening 321 is provided on the front plate 31.

The cover 6 covers the front plate 31 and covers the opening 321. The flap 6 may be a straight strip. The extending direction of the shield cover 6 is substantially the same as the extending direction of the front plate 31. The cover 6 is detachably connected to the main housing 31, such as by magnetic attraction, snap, screw, or pin.

As shown in fig. 4, the shield cover 6 includes a first strip 61 and a second strip 62. The first strip-shaped plate 61 and the second strip-shaped plate 62 are both straight strip-shaped. The first strip 61 may be a substantially flat plate. The second strip 62 may be an arcuate plate. The first strip 61 and the second strip 62 are both parallel to the extending direction of the opening 321. The bottom edge of the first strip 61 is interconnected with the top edge of the second strip 62. The first strip-shaped plate 61 and the second strip-shaped plate 62 form an included angle therebetween, so that the joint of the first strip-shaped plate 61 and the second strip-shaped plate 62 protrudes away from the main housing 31. The top edge of the first strip 61 abuts against the top edge of the front panel 31. The bottom edge of the second strip-shaped plate 62 abuts against the bottom edge of the front plate 31.

As shown in fig. 3 and 4, the control panel 2 is mounted on the outward facing surface of the first strip 61 of the cover 6. The control panel 2 and the first strip 61 of the cover 6 may be connected by a snap connection.

The control panel 2 further comprises a sealing sleeve 22 and a baffle 21. The sealing sleeve 22 has elasticity. Sealing boot 22 may be made of silicone or rubber. As shown in fig. 7, the sealing boot 22 includes a sealing gasket 221, a first protrusion 222, a second protrusion 223, a first cylinder 225, and a second cylinder 226. The gasket 221 is a flat gasket, and the shape of the gasket 221 is the same as that of the circuit board 23, and is preferably a rectangular flat gasket. The gasket 221 is overlaid on the circuit board 23 and aligned with the circuit board 23. The gasket 221 is provided with a window 224. The window 224 may be a rectangular through hole. The display device 233 is disposed through the window 224.

As shown in fig. 8, the first and

second projections

222 and 223 project in a direction away from the circuit board 23. The first and

second projections

222 and 223 may be substantially columnar projections. The first protrusion 222 and the second protrusion 223 each have a groove therein. The first protrusion 222 receives the first key switch 231, and the second protrusion 223 receives the second key switch 232.

As shown in fig. 7, the cross-section of the first cylinder 225 may be rectangular. The first cylinder 225 is disposed on the side of the gasket 221 adjacent to the circuit board 23. One end of the first cylinder 225 is connected to the sealing pad 221. The first cylinder 225 extends along the edge of the sealing pad 221. The inner wall of the first cylinder 225 abuts against the end face of the circuit board 23. The distance between the end surface of the first cylinder 225 facing away from the seal pad 221 and the seal pad 221 is greater than the thickness of the circuit board 23. Thus, the cavity enclosed by the first cylinder 225 and the gasket 221 accommodates the circuit board 23.

As shown in fig. 7 and 9, the cross-section of the second cylinder 226 may be rectangular. The second cylinder 226 is disposed on a side of the gasket 221 facing away from the circuit board 23. One end of the second cylinder 226 is connected to the packing 221. One end of the second cylinder 226 surrounds the window 224. The second cylinder 226 surrounds the display device 233. The end surface of the second cylinder 226 facing away from the gasket 221 and the end surface of the display device 233 facing away from the circuit board 23 may be flush with each other. In this way, the second cylinder 226 houses the display device 233.

As shown in fig. 4 and 8, the baffle plate 21 includes a plate body 213 and a sleeve 214. The plate body 213 is configured in a substantially flat plate shape, and the plate body 213 may be a straight flat plate. The plate body 213 is parallel to the circuit board 23. One end of the sleeve 214 is connected to one plate surface of the plate body 213. The sleeve 214 may be a rectangular cylinder. The plate body 213 is provided with a display region 215, a first mounting hole 211, and a second mounting hole 212. The display area 215, the first mounting hole 211 and the second mounting hole 212 are located in an area where the plate body 213 is enclosed by the sleeve 214. The display area 215 is transparent. The display area 215 may be made of transparent plastic or transparent glass. The first mounting hole 211 and the second mounting hole 212 are both through holes. The first mounting hole 211 and the second mounting hole 212 are through holes, and may be circular holes.

The cover 21 covers the sealing sleeve 22 from the side of the sealing sleeve 22 facing away from the circuit board 23. The sealing sleeve 22 is sandwiched between the circuit board 23 and the baffle 21. The sleeve 214 of the baffle 21 is sleeved outside the sealing sleeve 22, and the first protrusion 222 and the second protrusion 223 on the sealing gasket 221 protrude towards the plate body 213 of the baffle 21. The first and

second protrusions

222 and 223 are aligned with the first and second mounting

holes

211 and 212 of the plate body 213, respectively. The display area 215 is aligned with the display device 233, and the content displayed on the display device 233 can be displayed through the display area 215.

As shown in fig. 4 and 8, the control panel 2 further includes a first button 25 and a second button 26. The outer contours of the first button 25 and the second button 26 may be cylindrical. The first button 25 and the second button 26 may be made of hard plastic. The first button 25 is inserted into the first mounting hole 211. The first button 25 abuts on the top of the first protrusion 222. The second button 26 is disposed through the second mounting hole 212. The second button 26 abuts on the top of the second projection 223.

When the finger presses the first button 25, the first protrusion 222 is elastically deformed and presses the key of the first key switch 231, and the first key switch 231 is triggered. When the finger releases the first button 25, the first protrusion 222 returns to the original state, the first button 25 returns to the position before the finger is pressed by the elastic force of the first protrusion 222, and the button of the first key switch 231 is rebounded to the original state by the elastic member inside the first key switch 231. Similarly, when the finger presses the second button 26, the second button 26 may also press the key of the second key switch 232 through the second protrusion 223 to trigger the second key switch 232; after the finger releases the second button 26, the second protrusion 223 and the second key switch 232 are all restored to the initial state.

Pressing the first button 25 controls the pre-cooling of the electronic shower 1, and pressing the second button 26 controls the regular discharge of the pre-cooling of the electronic shower 1. Since the first button 25 and the second button 26 are both solid buttons and are elastically supported by the sealing sleeve 22, the impact force of water droplets splashed on the first button 25 or the second button 26 to the first button 25 or the second button 26 during showering cannot press the first button 25 or the second button 26, and therefore, the first key switch 231 and the second key switch 232 cannot be mistakenly triggered by the water droplets dripped from showering during showering. Meanwhile, as the sealing sleeve 22 is arranged between the circuit board 23 and the baffle 21, and the sealing sleeve 22 wraps the circuit board 23, water enters the control panel 2 from the gap between the first button 25 and the first mounting hole 211 and then is blocked by the sealing sleeve 22, and the water can not contact the circuit board 23 and devices on the circuit board 23, so that the damage of the circuit board 23 and the devices on the circuit board 23 is avoided.

In addition, because the circuit board 23 and the sealing sleeve 22 are both accommodated in the sleeve 214 of the baffle plate 21, water penetrating into the control panel 2 from the edge of the plate body 213 of the baffle plate 21 can only drip down along the peripheral wall of the sleeve 214, and cannot contact the circuit board 23 in the sleeve 214, thereby further improving the waterproof effect.

In an exemplary embodiment, as shown in fig. 6, the control circuit 235 further includes an internet of things control module. The Internet of things control module can be in wireless connection with other mobile terminals. The mobile terminal can be a mobile phone, a tablet computer or a smart sound box. The internet of things control module can receive a remote control signal sent by the mobile terminal, and the remote control signal takes radio waves as a carrier.

In this embodiment, the remote control signal may be a pre-chilled water discharge trigger or a regular water discharge trigger.

Therefore, the electronic shower can be remotely controlled by the mobile terminal to pre-discharge cold water and conventional water, a user does not need to enter a bathroom to operate the electronic shower, and the electronic shower is more convenient.

In an exemplary embodiment, the inner circumferential wall of the sleeve 214 of the baffle 21 abuts the outer circumferential wall of the first cylinder 225. The inner peripheral wall of the first cylinder 225 abuts against the end surface of the circuit board 23. The circuit board 23 and the sleeve 214 clamp the first cylinder 225, and the first cylinder 225 seals a gap between the circuit board 23 and the sleeve 214, so that water permeating from the gap between the first mounting hole 211 and the first button 25 or the gap between the second mounting hole 212 and the second button 26 cannot pass through the gap between the circuit board 23 and the sleeve 214, further improving waterproof performance.

In an exemplary embodiment, an end surface of the first button 25 facing an end of the circuit board 23 is recessed inward to form a receiving groove 253. The receiving groove 253 may be a circular groove. The receiving groove 253 can receive a portion of the first protrusion 222. The first button 25 is fitted over the first protrusion 222 and the first cylinder 227, and the first button 25 does not move in the radial direction.

In an exemplary embodiment, as shown in fig. 7 and 8, boot seal 22 further includes a first cylinder 227. The first cylinder 227 is disposed on top of the first protrusion 222. First cylinder 227 may be coaxially disposed with first boss 222. The first cylinder 227 has elasticity. The first cylinder 227 is provided with a first positioning recess 228 at an end facing the first button 25. The cross-sectional shape of the first positioning recess 228 is non-circular, and the cross-sectional shape of the first positioning recess 228 may be a cross. The groove bottom of the receiving groove 253 of the first button 25 is provided with a first positioning protrusion 252. The first seating protrusion 252 is inserted into the first seating groove 228. The first positioning protrusion 252 has the same cross-section as the first positioning groove 228.

After the first positioning protrusion 252 is inserted into the first positioning groove 228, the first button 25 cannot rotate relative to the first protrusion 222, and the first button 25 is more stably installed.

In an exemplary embodiment, the first button 25 is provided with a first position-limiting portion 251. The first stopper 251 is provided on the outer peripheral wall of the first button 25. The first stopper 251 may be a protrusion surrounding the first button 25. The first position-limiting portion 251 is located on one side of the board body 213 facing the circuit board 23.

The first position-limiting portion 251 cannot pass through the first mounting hole 211, so that the first button 25 cannot be taken out of the first mounting hole 211.

In one exemplary embodiment, as shown in fig. 9 and 10, the control panel 2 further includes a light barrier 24. The light-blocking pad 24 has a substantially plate-like structure. The light-blocking pad 24 is made of a light-tight material, and the light-blocking pad 24 may be black. The light-blocking pad 24 is disposed between the display region 215 of the plate body 213 and the display device 233. The light blocking pad 24 may be a rectangular pad. The light blocking pad 24 is provided with a plurality of light transmission holes 241. The display device 233 includes a plurality of light-emitting regions 234 on the surface facing the display region 215. A light source, which may be a light emitting diode, is disposed in each light emitting region 234. The light transmitting holes 241 and the light emitting regions 234 may be disposed in a one-to-one correspondence, the cross-sectional shape of the light transmitting hole 241 may be the same as the shape of the light emitting region 234 corresponding to the light transmitting hole 241, and each light transmitting hole 241 may be aligned with its corresponding light emitting region 234. Each light-transmitting hole 241 transmits only light emitted from the corresponding light-emitting region 234.

Since the board body 213 usually needs to be surface-treated with a sub-white color, if the light-blocking pad 24 is not disposed, the light emitted from the display device 233 will be diffused when it strikes the sub-white surface of the display region 215 of the board body 213, and thus the display region 215 cannot clearly display the content displayed by the display device 233. After the light-blocking pad 24 is disposed, each light-transmitting hole 241 on the light-blocking pad 24 only transmits the light of the light-emitting region 234 corresponding to the light-transmitting opening, and other scattered light is blocked by the light-blocking pad 24, so that the final displayed content of the display region 215 of the plate body 213 is clearer.

The first chamber 451 is a generally cylindrical chamber. The thermostatic cartridge 51 is mounted into the first chamber 451. The second chamber 452 is arranged at an end of the valve body 4 facing away from the first chamber 451. The second chamber 452 is formed by the other end surface of the valve body 4 being recessed. The second chamber 452 is a substantially cylindrical chamber. The second chamber 452 may be coaxially disposed with the first chamber 451. A water diverter spool 52 is mounted in the second chamber 452. The third chamber 453 is recessed from the side of the valve body 4. The third chamber 453 may be located between the first chamber 451 and the second chamber 452. The solenoid valve 53 is partially inserted into the third chamber 453.

The cold water port 422 and the hot water port 421 are both proximate the first chamber 451. One end of the hot water pipe 41 is connected to the hot water port 421, and the other end of the hot water pipe 41 is connected to a hot water supply pipe (not shown). The hot water supply pipe is used to inject hot water into the hot water pipe 41. The cold water port 422 is used to connect a cold water supply pipe. A cold water supply pipe (not shown) is used to fill cold water into the cold water connection 422.

The hot water flow passage 431 extends from the hot water port 421 to the first chamber 451.

Cold water flow passage 432 extends from cold water port 422 to first chamber 451. The cold water flow passage 432 connects the cold water port 422 to the cold water inlet of the thermostatic cartridge 51.

The first mixing flow path 433 extends from the first chamber 451 to the third chamber 453. The first mixing flow path 433 connects the constant temperature outlet of the constant temperature spool 51 to the first port of the solenoid valve 53.

The second mixing flow path 434 extends from the second chamber 452 to the third chamber 453. The second mixed water flow passage 434 communicates the inlet of the water distribution valve spool 52 with the second port of the solenoid valve 53.

The first water outlet 461 may be arranged facing downwards. A first branch flow passage extends from the second chamber 452 to the first water outlet port 461. The first branch flow passage connects the first water outlet of the water distribution valve core 52 with the first water outlet port 461 of the valve body 4.

The second water outlet port 462 may be disposed downward. A second branch flow passage extends from the second chamber 452 to a second water outlet port 462. The second branch flow passage connects the second water outlet of the water diversion valve core 52 with the second water outlet port 462 of the valve body 4.

When the water distribution valve body 52 is switched to connect the water inlet and the first water outlet and the electromagnetic valve 53 is opened, the hot water supplied from the hot water supply pipe passes through the hot water pipe 41, the hot water port 421 and the hot water flow passage 431 in order and enters the hot water inlet of the thermostatic valve body 51, and the cold water supplied from the cold water supply pipe passes through the cold water port 422 and the cold water flow passage 432 in order and enters the cold water inlet of the thermostatic valve body 51. After the hot water and the cold water are mixed in the thermostatic valve core 51 to form mixed water, the mixed water is output from the thermostatic outlet of the thermostatic valve core 51 to the first mixed water flow channel 433, and the mixed water passes through the first mixed water flow channel 433, the electromagnetic valve 53, the second mixed water flow channel 434, the water diversion valve core 52 and the first branch flow channel in sequence and is finally output from the first water outlet port 461. The first water outlet 461 may be externally connected to a water outlet pipe.

When the water diversion valve core 52 is switched to connect the water inlet and the second water outlet and the electromagnetic valve 53 is opened, the hot water and the cold water are mixed in the thermostatic valve core 51 to form mixed water, the mixed water is output to the first water mixing flow channel 433 from the thermostatic outlet of the thermostatic valve core 51, and the mixed water sequentially passes through the first water mixing flow channel 433, the electromagnetic valve 53, the second water mixing flow channel 434, the water diversion valve core 52 and the second branch flow channel and is finally output from the second water outlet port 462. The second water outlet 462 can be externally connected with the shower head 71.

When the water diversion valve core 52 is switched to connect the water inlet and the third water outlet and the electromagnetic valve 53 is opened, the hot water and the cold water are mixed into mixed water in the thermostatic valve core 51, the mixed water is output to the first water mixing flow channel 433 from the thermostatic outlet of the thermostatic valve core 51, and the mixed water sequentially passes through the first water mixing flow channel 433, the electromagnetic valve 53, the second water mixing flow channel 434, the water diversion valve core 52 and the third branch flow channel 435, and is finally output from the third water outlet connector 463. The third water outlet 463 may have an external top shower 72.

When the electromagnetic valve 53 is closed, the mixed water in the first mixed water channel 433 cannot reach the second mixed water channel through the electromagnetic valve 53, and therefore, no water can be discharged from the first water outlet port 461, the second water outlet port 462 and the third water outlet port 463, so that the electromagnetic valve 53 can control whether the electronic shower 1 can discharge water, and simultaneously, the water outlet ports can be switched through the water diversion valve core 52 during water discharge. This eliminates the need for multiple solenoid valves 53 to control the drainage of multiple outlet ports, respectively.

In an exemplary embodiment, as shown in fig. 13, a fourth chamber 454 is also provided on the valve body 4. The fourth chamber 454 may be located between the first mixing flow path 433 and the second mixing flow path 434, and both the first mixing flow path 433 and the second mixing flow path 434 are communicated with the fourth chamber 454. The fourth chamber 454 may be disposed at one side of the second chamber 452.

The electronic shower 1 also comprises a mechanical valve 54. The mechanical valve 54 is provided with two ports. The mechanical valve 54 is disposed within the fourth chamber 454. Two ports of the mechanical valve 54 are respectively communicated with the first mixing flow passage 433 and the second mixing flow passage 434. The mechanical valve 54 may be opened and closed manually.

When the electromagnetic valve is closed and the mechanical valve 54 is opened, the first mixing flow channel 433 is communicated with the second mixing flow channel 434, and the electronic shower 1 discharges water outwards. When the electromagnetic valve is closed and the mechanical valve 54 is closed, the first mixing flow channel 433 and the second mixing flow channel 434 are cut off, and the electronic shower 1 stops draining water outwards. In this way, the user can also open and close the electronic shower 1 by operating the mechanical valve 54 when the solenoid valve is damaged.

In an exemplary embodiment, as shown in fig. 3, the electronic shower 1 further comprises a connection assembly. The connecting assembly includes a connecting member 81, a first screw 83 and a second screw 82. The connector 81 includes a first connecting cylinder 811.

The second screw 82 is screwed into the second screw hole 622 through the coupling hole 813, and the screw coupling is formed between the shield cover 6 and the first coupling cylinder 811.

Thus, the coupling assembly couples the shield cover 6 and the bottom plate 37 to each other. When the blocking cover 6 needs to be detached from the main housing 31, the blocking cover 6 and the connecting member 81 can be detached from the main housing 31 only by screwing off the first screw 83. When it is necessary to newly mount the blocking cover 6 to the main housing 31, the connecting member 81 connected to the blocking cover 6 is simply connected to the bottom plate 37 of the main housing 31 by the first screw 83, thereby facilitating maintenance of the solenoid valve 53 and the control panel 2.

In an exemplary embodiment, the connector 81 further includes a second connector barrel 814. The second connector barrel 814 is of a cylindrical configuration. One end of the second connector cylinder 814 is connected to the outer circumferential wall of the first connector cylinder 811.

The second connecting cylinder 814 is coaxially disposed with the coupling hole 813 of the first connecting cylinder 811, and the inner hole diameter of the second connecting cylinder 814 is larger than the diameter of the coupling hole 813.

The second connector barrel 814 is fitted over the connector string 621 to make the connection between the connector 81 and the shield cover 6 more stable.

In an exemplary embodiment, as shown in fig. 2, the electronic shower 1 further includes a battery assembly 92. The battery assembly 82 is disposed within the main housing 31.

The decorative plate 93 is a flat plate, and the surface of the decorative plate 93 is horizontally arranged. The decorative plate 93 can be used for placing articles, such as shampoo, bath lotion, etc.

As shown in fig. 14, the present embodiment also proposes a control method of the electronic shower 1, which can be implemented based on the electronic shower 1. The control method comprises the following steps:

s1: the control circuit 235 receives a pre-discharge cold water trigger signal;

s2: the control circuit 235 drives the electromagnetic valve 53 to open so as to enable the electronic shower 1 to discharge water;

s3: the control circuit 235 determines whether the outlet water temperature of the electronic shower 1 exceeds a first preset temperature, if so, the process goes to step S4, otherwise, the process goes to step S3;

s4: the control circuit 235 drives the electromagnetic valve 53 to close so that the electronic shower 1 stops water outlet;

in an exemplary embodiment, the control method further includes step S5 after step S2.

In an exemplary embodiment, the control method further includes step S6 after step S2.

S6: the control circuit 235 obtains a first temperature value of the outlet water temperature of the electronic shower 1 when the opening time of the electromagnetic valve 53 reaches a second preset time;

s7: when the temperature value of the outlet water temperature of the electronic shower 1 is kept unchanged within a third preset time period, the control circuit 235 determines the temperature value as a second temperature value;

s8: judging whether the difference between the second temperature value and the first temperature value is greater than or equal to a preset temperature difference, if so, entering step S9, otherwise, entering step S7;

s9: and judging whether the second temperature value is greater than or equal to a second preset temperature, if so, entering step S3, and otherwise, entering step S7.

In an exemplary embodiment, the control method further includes step S10 after step S2.

s11: the control circuit 235 determines whether the solenoid valve 53 is in the open state, and if so, the process proceeds to step S4, otherwise, the process proceeds to step S2.

After the first key switch is pressed again, the control circuit 235 receives the pre-cooling water discharging triggering signal again. Then, the control circuit 235 determines whether the solenoid valve 53 is in an open state, and drives the solenoid valve 53 to close if the solenoid valve is in the open state. In this way, the preliminary cold water discharge can be terminated in advance by pressing the first key switch again.
