Description

Technical Field

[0001] This invention belongs to the field of bathroom equipment technology, specifically relating to a highly stable intelligent shower with independent control of hot and cold water. Background Technology

[0002] Currently, existing smart shower boxes generally consist of a shower box shell, a mixing valve, a switching valve, and a diverter valve. The mixing valve controls the water temperature by rotating to regulate the flow of cold and hot water. The switching valve controls the flow of the mixed water into the powder valve, from which it is directly discharged by the diverter valve. Existing smart shower boxes have the following problems: 1. Since cold and hot water are mixed by the mixing valve, a check valve needs to be installed inside the smart shower box to prevent cross-contamination between cold and hot water; 2. The water circuit of existing smart showers requires passing through the mixing valve, the switching valve, and a second electronic rotary switching valve, resulting in high water flow resistance. In view of this, this solution was developed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a highly stable intelligent shower with independent control of hot and cold water, which has low water flow resistance and stable operation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a highly stable intelligent shower with independent control of hot and cold water, including a shower box shell, wherein a cold water channel, a hot water channel, a hot and cold water mixing channel and multiple distribution channels are formed on the shower box shell, and a cold water outlet, a hot water outlet, two hot and cold water mixing inlets, a hot and cold water mixing outlet and multiple distribution inlets are formed on the upper surface of the shower box shell; The cold water outlet and the cold water channel are interconnected, the hot water outlet and the hot water channel are interconnected, the hot and cold water mixing outlet and the two hot and cold water mixing inlets are interconnected with the hot and cold water mixing channel, and the multiple distribution channels are interconnected with multiple distribution inlets respectively; The cold water outlet and the hot and cold water mixing inlet are controlled by a first electronic rotary switch valve, the hot water outlet and the hot and cold water mixing inlet are controlled by a second first electronic rotary switch valve, and the hot and cold water mixing outlet and multiple distribution inlets are controlled by a second electronic rotary switch valve.

[0005] Furthermore, the first electronic rotary switch valve includes a first driving member and a first rotating block. A crescent-shaped connecting groove is formed on the lower surface of the first rotating block. When the first rotating block rotates, the area of ​​the overlapping region between the crescent-shaped connecting groove and the hot and cold water mixing inlet increases linearly or geometrically. The flow rate of the mixing channel inlet is proportional to the square of the area of ​​the overlapping region between the crescent-shaped connecting groove and the mixing channel. Furthermore, a first pressure block is provided between the first rotating block and the shower box housing. The first pressure block has a first through hole and a second through hole. The first through hole corresponds to the hot water outlet or the cold water outlet, and the second through hole corresponds to the hot and cold water mixing inlet.

[0006] Furthermore, the second through hole has an enlarged groove formed in the opening. The enlarged groove is crescent-shaped. When the first rotating block rotates, the area of ​​the overlapping region between the crescent-shaped groove and the enlarged groove increases linearly or geometrically.

[0007] Furthermore, a protruding part is formed on one side of the crescent-shaped connecting groove. The two sides of the protruding part are connected to the small diameter side line and the large diameter side line of the connecting groove through concave arcs. When connecting the cold water outlet or hot water outlet, the cold and hot water mixing inlet and the crescent-shaped connecting groove, the protruding part first coincides with the cold and hot water mixing inlet.

[0008] Furthermore, multiple distribution inlets are arranged in a ring around the hot and cold water mixing outlet, and there is a partition area between any adjacent distribution inlets. The second electronic rotary switch valve controls the hot and cold water mixing outlet to communicate with the distribution inlets or the partition area.

[0009] Furthermore, the second electronic rotary switch valve includes a second driving member and a second rotating block, the second rotating block being connected to the output end of the second driving member, and a strip-shaped hole extending outward from the center of the lower surface of the second rotating block; A second pressure block is also provided between the second rotating block and the upper surface of the shower box housing. The second pressure block has a first adapter hole, a second adapter hole and a partition groove corresponding to the hot and cold water mixing outlet, the distribution inlet and the partition area. The rotation of the second rotating block causes the strip hole to connect with the first adapter hole and the second adapter hole, or the first adapter hole and the partition groove.

[0010] Furthermore, the smart shower also includes an upper outer shell and a lower outer shell, the lower outer shell being used to enclose the shower box housing, and an electrical chamber being formed inside the upper outer shell, the electrical chamber being used to accommodate the first driving component and isolate the shower box housing and the first driving component.

[0011] Furthermore, the smart shower also includes an upper outer shell and a lower outer shell, the lower outer shell being used to enclose the shower box housing, and an electrical chamber being formed inside the upper outer shell, the electrical chamber being used to accommodate the second drive component and isolate the shower box housing and the second drive component.

[0012] Furthermore, three mounting grooves are formed on the lower surface of the upper outer shell. The three mounting grooves are used to install the components of the two first electronic rotary switch valves and the second electronic rotary switch valve. The upper end of the mounting groove is sealed to the connection of the first electronic rotary switch valve or the second electronic rotary switch valve. The two first electronic rotary switch valves or the second electronic rotary switch valves are respectively sealed to the cold water outlet and the cold and hot water mixing inlet, the hot water outlet and the cold and hot water mixing inlet and the cold and hot water mixing outlet and multiple distribution inlets. An air gap is formed between the upper outer shell and the shower box shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the cold water channel and hot water channel on the shower box shell are controlled by an independent first electronic rotary switch valve. The first electronic rotary switch valve adjusts the water flow from the cold water outlet and the hot water outlet according to the command, which enters the cold and hot water mixing channel. Then, the water flow is directly distributed to the distribution channel through the second electronic rotary switch valve. Compared with existing smart shower boxes, the water flow in this application only needs to pass through the switch valve and the second electronic rotary switch valve for use, resulting in low water flow resistance. Moreover, since the cold water channel and the hot water channel are controlled by an independent first electronic rotary switch valve, the smart shower of this solution does not need to be equipped with a check valve to prevent cross-flow, making the overall structure simpler. Due to the reduction of many components (mixing valve, check valve, etc.), the overall volume of the smart shower of this solution is reduced by 40-50% compared with existing showers, and the operation is more stable and less prone to damage.

[0014] 2. Under low flow conditions of cold or hot water, uneven mixing may occur, manifesting as a deviation of the water temperature in the hot and cold water mixing channel from the preset value. To solve this problem, this solution incorporates a crescent-shaped connecting groove on the lower surface of the first rotating block. As the first rotating block rotates, the area of ​​the crescent-shaped connecting groove overlapping with the hot and cold water mixing inlet increases linearly or geometrically. When the area of ​​the crescent-shaped connecting groove overlapping with the mixing channel inlet increases linearly, the water flow rate controlled by the software increases geometrically, ensuring constant pressure water output under low flow conditions and preventing unstable water output.

[0015] 3. In existing smart showers, when the switch valve is damaged, water will directly enter the second electronic rotary switch valve and then flow out, failing to effectively stop the water flow. To avoid this problem, this solution sets up an isolation zone in the control area of ​​the second electronic rotary switch valve. When the strip hole on the second rotating block of the second electronic rotary switch valve rotates to the isolation groove position, even if the switch valve (first electronic rotary switch valve) is damaged, the smart shower of this solution will not flow water.

[0016] 4. The cold water and hot water channels on the smart shower in this solution do not need to be precisely matched with the cold water and hot water pipes. Even if the cold water and hot water pipes are connected in reverse, when there is abnormal temperature reaction in the mixed water in the cold and hot water mixing channel, the control circuit board of this solution can promptly identify that the cold water and hot water pipes are connected in reverse, and then the program controls the switching of the corresponding channels of the cold water and hot water pipes to achieve automatic correction.

[0017] 5. In this design, an air gap is formed between the upper outer shell and the shower box shell. When water leaks between the inlet and outlet of the shower box shell and the first or second electronic rotary switch valve, it will flow directly out through the air gap and will not overflow into the electrical chamber. In existing smart showers, the water vapor chamber (the water inlet and outlet on the shower box shell) and the electrical chamber are only sealed by a sealing ring. When water leaks at either the water inlet or outlet, a pressure difference will occur between the electrical chamber and the water vapor chamber. This pressure difference will cause the sealing ring to be squeezed, eventually leading to water seeping into the electrical chamber. Attached Figure Description

[0020] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0021] like Figures 1-17As shown, this embodiment provides a highly stable intelligent shower with independent control of hot and cold water, including a shower box housing 1, two first electronic rotary valves 2, a second electronic rotary valve 3, an upper outer shell 4, and a lower outer shell 5.

[0022] The shower box housing 1 has a cold water channel 11, a hot water channel 12, a hot and cold water mixing channel 13, and four distribution channels 14. The upper surface of the shower box housing 1 has a cold water outlet 111, a hot water outlet, two hot and cold water mixing inlets 131, a hot and cold water mixing outlet 132, and multiple distribution inlets 141. The cold water outlet 111 is connected to the cold water channel 11, the hot water outlet is connected to the hot water channel 12, the hot and cold water mixing outlet 132 and the two hot and cold water mixing inlets 131 are connected to the hot and cold water mixing channel 13, and the four distribution channels 14 are connected to the multiple distribution inlets 141 respectively.

[0023] The cold water inlet 121 of the cold water channel 11 is located on the side of the shower box housing 1, the hot water inlet of the hot water channel 12 is located on the side of the shower box housing 1, and the four distribution channels 14 have two distribution outlets located on the other side of the shower box housing 1, and the other two distribution outlets located on the lower surface of the shower box housing 1.

[0024] The cold water outlet 111 and one of the cold and hot water mixing inlets 131 are controlled by a first electronic rotary switch valve 2, the hot water outlet and another cold and hot water mixing inlet 131 are controlled by a second first electronic rotary switch valve 2, and the cold and hot water mixing outlet 132 and four distribution inlets 141 are controlled by a second electronic rotary switch valve 3.

[0025] In existing smart showers, when the switch valve is damaged, water will directly enter the second electronic rotary switch valve 3 and then flow out, failing to effectively stop the water flow. To avoid this problem, this solution sets up an isolation zone 15 in the control area of ​​the second electronic rotary switch valve 3. When the strip hole 3241 on the second rotating block 32 of the second electronic rotary switch valve 3 rotates to the position of the isolation groove 333, even if the switch valve (first electronic rotary switch valve 2) is damaged, the smart shower of this solution will not flow water.

[0026] In this solution, the cold water channel 11 and hot water channel 12 on the smart shower do not need to be precisely matched with the cold water pipe and hot water pipe. Even if the cold water pipe and hot water pipe are connected in reverse, when the temperature reaction of the mixed water in the cold and hot water mixing channel 13 is abnormal, the control circuit board of this solution can promptly identify that the cold water pipe and hot water pipe are connected in reverse, and then the program controls the switching of the corresponding channels of the cold water pipe and hot water pipe to achieve automatic correction.

[0027] The first electronic rotary switch valve 2 includes a first driving element 21 and a first rotating block 22. The first driving element 21 is a motor. A crescent-shaped connecting groove 24 is formed on the lower surface of the first rotating block 22. When the first rotating block 22 rotates, the area of ​​the crescent-shaped connecting groove 24 overlapping with the hot and cold water mixing inlet 131 increases linearly. Specifically, a protruding nozzle 241 is formed on one side of the crescent-shaped connecting groove 24. The two sides of the protruding nozzle 241 are connected to the small diameter edge line and the large diameter edge line of the connecting groove through concave arcs. When connecting the cold water outlet 111 or the hot water outlet, the hot and cold water mixing inlet 131 and the crescent-shaped connecting groove 24, the protruding nozzle 241 first overlaps with the hot and cold water mixing inlet 131.

[0028] A first pressure block 23 is also provided between the first rotating block 22 and the shower box housing 1. A first through hole 231 and a second through hole 232 are formed on the first pressure block 23. The first through hole 231 corresponds to the hot water outlet or the cold water outlet 111, and the second through hole 232 corresponds to the hot and cold water mixing inlet 131. A sealing groove is formed on the outer periphery of the cold water outlet 111, the hot and cold water mixing inlet 131 and the hot water outlet. A sealing ring 6 is provided in the sealing groove, and the first pressure block 23 presses the sealing ring 6.

[0029] In a preferred embodiment of this application, an enlarged groove 233 is formed on the opening of the second through hole 232. The enlarged groove 233 is crescent-shaped. When the first rotating block 22 rotates, the area of ​​the overlapping region between the crescent-shaped connecting groove 24 and the enlarged groove 233 increases linearly or geometrically. In this solution, the geometric increase method is adopted, which makes it easier for the software to control the flow.

[0030] When the flow rate of cold or hot water is low, uneven mixing of water may occur, which manifests as a deviation of the water temperature in the hot and cold water mixing channel 13 from the preset value. To solve this problem, this solution sets a crescent-shaped connecting groove 24 on the lower surface of the first rotating block 22. When the first rotating block 22 rotates, the area of ​​the overlapping region between the crescent-shaped connecting groove 24 and the hot and cold water mixing inlet 131 increases geometrically. Then, the flow rate relationship on the control software is linear. With this setting, the stability of the water output can be guaranteed even at low flow rates.

[0031] Four distribution inlets 141 are arranged in a ring around the hot and cold water mixing outlet 132. There is a partition zone 15 between any adjacent distribution inlets 141. The second electronic rotary switch valve 3 controls the hot and cold water mixing outlet 132 to communicate with the distribution inlets 141 or the partition zone 15. A closed-loop sealing groove is provided on the outer periphery of the four distribution inlets 141 and the hot and cold water mixing outlet 132. The closed-loop sealing groove surrounds the four distribution inlets 141 and the hot and cold water mixing outlet 132. A matching irregular sealing ring 6 is provided in the closed-loop sealing groove.

[0032] The second electronic rotary switch valve 3 includes a second drive member 31 and a second rotating block 32. The second drive member 31 is a motor. The second rotating block 32 is connected to the output end of the second drive member 31. A strip-shaped hole 3241 extending outward is formed in the middle of the lower surface of the second rotating block 32. A second pressure block 33 is also provided between the second rotating block 32 and the upper surface of the shower box housing 1. The second pressure block 33 presses the irregular sealing ring 6. The second pressure block 33 has a first adapter hole 331, a second adapter hole 332 and a partition groove 333 corresponding to the hot and cold water mixing outlet 132, the distribution inlet 141 and the partition area 15. The rotation of the second rotating block 32 causes the strip-shaped hole 3241 to connect the first adapter hole 331 and the second adapter hole 332 or the first adapter hole 331 and the partition groove 333.

[0033] In existing smart showers, when the switch valve is damaged, water will directly enter the second electronic rotary switch valve 3 and then flow out, failing to effectively stop the water flow. To avoid this problem, this solution sets up an isolation zone 15 in the control area of ​​the second electronic rotary switch valve 3. When the strip hole 3241 on the second rotating block 32 of the second electronic rotary switch valve 3 rotates to the position of the isolation groove 333, even if the switch valve (first electronic rotary switch valve 2) is damaged, the smart shower of this solution will not flow water.

[0034] An electrical chamber 41 is formed inside the upper outer casing 4. Three mounting slots 42 are formed on the lower surface of the upper outer casing 4. A through hole is provided at the bottom of the mounting slot 42 for the output ends of the first driving member 21 and the second driving member 31 to pass through. The three mounting slots 42 are respectively used to install two first electronic rotary switch valves 2 and two electronic rotary switch valves 3. Specifically, an insertion slot 421 is also provided at the bottom of the mounting slot 42. A first boss 221 is formed on the upper surface of the first rotating block 22. The first boss 221 extends into the slot 421. A sealing ring 6 is provided between the first boss 221 and the insertion slot 421. Preferably, a gap is formed between the insertion slot 421 and the first boss 221. A first limiting ring 222 is formed below the first boss 221. The first limiting ring 222 extends into the insertion slot 421. A sealing ring 6 is provided between the insertion slot 421 and the first limiting ring 222. The upper surface of the second rotating block 32 has a second boss 321, which extends into the insertion groove 421. A sealing ring 6 is provided between the second boss 321 and the insertion groove 421. Preferably, a gap is formed between the insertion groove 421 and the second boss 321, and a second limiting ring 322 is formed below the second boss 321, which extends into the insertion groove 421.

[0035] An air gap is formed between the outer shell and the shower box housing through the above-mentioned arrangement, such as Figure 3 , Figure 5 and Figure 10As shown, the red area represents the air gap, and the air pressure in the air gap is atmospheric pressure. When there is a leak in the shower box housing and the first electronic rotary valve 2 or the second electronic rotary valve 3, water will flow directly out from the air gap.

[0036] The first rotating block 22 includes a first upper adapter block 223 and a first lower connecting block 224. The upper adapter block is connected to the output end of the first driving member 21. The crescent-shaped connecting groove 24 is located on the lower surface of the first lower connecting block 224. The first upper adapter block 223 and the first lower connecting block 224 are connected by snap-fit. Specifically, the outer edge of the upper surface of the first lower connecting block 224 has a plurality of annularly spaced first notches 2241. The lower surface of the first upper adapter block 223 is provided with a plurality of first locking blocks 2231, which are adapted to the first notches 2241.

[0037] The second rotating block 32 includes a second upper connecting block 323 and a second lower connecting block 324. The connection method of the second upper connecting block 323 and the second lower connecting block 324 is the same as that of the first upper connecting block 223 and the first lower connecting block 224, and will not be described again here.

[0038] Preferably, the upper surface of the shower box housing 1 is provided with a plurality of first connection holes 16, and the lower surface of the electrical chamber 41 is provided with a plurality of second connection holes 45. The first connection holes 16 and the second connection holes 45 correspond to each other and are connected by a connector, which is a screw.

[0039] In this design, the electrical components of the first electronic rotary valve 2 and the second electronic rotary valve 3 are all housed in the electrical chamber 41 of the upper housing 4. The upper housing 4 is connected to the control components of the first electronic rotary valve 2 and the second electronic rotary valve 3 via the mounting groove 42. This design only requires sealing the mounting groove 42 to achieve electrical isolation. Compared with existing smart showers, the electrical chamber 41 and the water chamber have more connections, making the smart shower of this design more stable.

[0040] The upper outer casing 4 includes a frame 43 and a cover plate 44. The electrical chamber 41 is located inside the frame 43. The frame 43 has an upper opening that communicates with the electrical chamber 41. The cover plate 44 is used to close the upper opening. A sealing ring 6 is provided at the connection between the frame 43 and the cover plate 44. Two limiting plates 46 are formed on two corresponding side walls of the frame 43. The two limiting plates 46 are spaced apart and a locking channel is formed between the two limiting plates 46. The two locking channels are used to lock the two sides of the circuit board.

[0041] The lower outer shell 5 is used to enclose the shower box housing 1. The shower box housing 1 is disposed inside the lower outer shell 5. The lower outer shell 5 and the shower box housing 1 are connected by a connector. Specifically, a connecting post 17 is formed on the shower box housing 1. The lower end face of the connecting post 17 has a third connecting hole. The lower outer shell 5 has a fourth connecting hole 51. The third connecting hole and the fourth connecting hole 51 correspond to each other. The lower outer shell 5 and the shower box housing 1 are connected by a connector screwed into the third connecting hole and the fourth connecting hole 51. The connector is a bolt.

[0042] In this invention, the cold water channel 11 and hot water channel 12 on the shower box housing 1 are controlled by an independent first electronic rotary switch valve 2. The first electronic rotary switch valve 2 adjusts the water flow from the cold water outlet 111 and the hot water outlet according to the command, so that the water enters the cold and hot water mixing channel 13. Then, the water flow is directly distributed to the distribution channel 14 through the second electronic rotary switch valve 3. Compared with existing smart shower boxes, the water flow in this application only needs to pass through the switch valve and the second electronic rotary switch valve 3 for use, resulting in low water flow resistance. Moreover, since the cold water channel 11 and hot water channel 12 are controlled by an independent first electronic rotary switch valve 2, the smart shower of this solution does not need to be equipped with a check valve to prevent cross-flow, and the overall structure is simpler. Due to the reduction of many components (mixing valve, check valve, etc.), the overall volume of the smart shower of this solution is reduced by 40-50% compared with existing showers, and the operation is more stable and less prone to damage.

[0043] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention.
