Description

Technical Field

[0001] This invention pertains to zero-cold-water control technology in the hot water pipes of solar-powered shower water heaters, gas-powered shower water heaters, and electric shower water heaters. Specifically, it relates to a shower water heater controlled by a zero-cold-water control switch in the hot water pipes. Background Technology

[0002] Currently, there are various types of shower water heaters on the market. During installation, because the hot water pipes are too long, the hot water in the pipes slowly cools down after showering. When showering again, the water in the pipes has to sit for a long time, resulting in water waste and making people prone to catching a cold while waiting. This problem has not yet received attention from manufacturers and users. Summary of the Invention

[0003] The purpose of this invention is to provide a shower water heater controlled by a zero-cold-water control switch in the hot water pipe, which solves the problem that the hot water in the pipe slowly cools down after showering, and the water in the pipe has to be left to stand for a long time before the next shower, resulting in water waste and the risk of people catching a cold while waiting.

[0004] A shower water heater controlled by a zero-cold-water control switch inside the hot water pipe. The zero-cold-water electromagnetic control switch 1 has a hot water drain connection pipe 19 connected to the outlet 20 of the electromagnet column housing, which is connected to the hot water drain pipe 5. The zero-cold-water electromagnetic control switch hot water outlet connection pipe 22 is connected to the hot water inlet 21 of the electromagnet column housing, which is connected to the bottom of the water heater heating tank 2. The water heater heating tank 2 has an overflow pipe 3 on the upper right side. The hot water drain pipe 5 is connected to a cold water pipe 4 at the top and a cold water supply pipe 8 at the bottom. A manual cold water switch 6 controls the water flow and cold water supply. Pipe 8 is equipped with a cold water supply solenoid control valve 7. The lower end of the hot water drain pipe 5 is connected to the shower head 10. The water flow is controlled by a manual shower head switch 9. The control circuits of the zero cold water solenoid control switch sensor 11, the zero cold water solenoid control switch 1, and the cold water supply solenoid valve 7 are connected to the fully intelligent water heater controller 12. The spring fixing cover 14 of the zero cold water solenoid control switch 1 is fixed to the outer shell of the coil 16. The spring 13 presses against the electromagnet column 15. When the coil 16 is energized, the electromagnet column 15 is attracted, and the outlet 23 of the electromagnet column coincides with the outlet 20 of the outer shell of the electromagnet column. When the inlet 24 of the magnetic column coincides with the hot water inlet 21 of the electromagnet column housing, the hot water circuit is connected. When the coil 16 of the zero cold water electromagnetic control switch is de-energized, the electromagnet column 15, under the action of the spring force, has its air outlet 26 coinciding with the water outlet 20 of the electromagnet column housing, and its other end coinciding with the air inlet 18 of the electromagnet column housing. This utilizes atmospheric pressure to empty the water in the hot water drain pipe 5. This emptying of the hot water drain pipe 5 is achieved after showering, by closing the manual cold water switch 6 and opening the manual shower head switch 9. The hot water drain pipe 5 also... The water heater heating tank 2 is responsible for supplying cold water. A water blocker 27 is placed inside the air passage 17 of the electromagnet column. The water blocker 27 has a water blocking cylinder inlet 28 at the top and a crossbar 32 for fixing the piston shaft at the bottom. The two ends of the crossbar are welded to the bottom of the water blocking cylinder. The piston shaft 30 is vertically welded to the middle of the crossbar 32 for fixing the piston shaft. The sliding sleeve 35 of the lower water blocking rubber piston 31 is fitted on the bottom of the piston shaft 30, and the sliding sleeve 35 of the upper water blocking rubber piston 29 is fitted on the top of the piston shaft 30. The upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 are separated and overlapped.

[0005] The energization or de-energization of the zero-cold-water electromagnetic control switch coil 16 is determined by whether the showerer approaches or leaves the zero-cold-water electromagnetic control switch sensor 11. When the showerer approaches the zero-cold-water electromagnetic control switch sensor 11, the zero-cold-water electromagnetic control switch coil 16 is energized; when the showerer leaves the zero-cold-water electromagnetic control switch sensor 11, the zero-cold-water electromagnetic control switch coil 16 is de-energized.

[0006] When a strong water flow impacts the lower water-blocking rubber piston 31, the lower water-blocking rubber piston 31 moves upward, pushing the upper water-blocking rubber piston 29 upward. This causes the upper water-blocking rubber piston head 33 to block the inner opening 28 of the water blocker. Under continuous water pressure, the electromagnet column 15 overcomes the spring force and begins to move upward, causing the outlet 23 of the electromagnet column to coincide with the outlet 20 of the electromagnet column housing, and the inlet 24 of the electromagnet column to coincide with the hot water inlet 21 of the electromagnet column housing. The cold water path is then connected to the heating tank 2 of the water heater. Using the water blocker 27 to fill the water heater heating tank 2 with cold water, the zero cold water electromagnetic control switch 1 can be directly turned on to fill the water heater heating tank 2 with cold water. However, since the water heater heating tank 2 is filled with cold water for a long time without interruption, the coil of the zero cold water electromagnetic control switch 1 is prone to burnout. The diameter of the water-blocking rubber piston film 34 of the upper water-blocking rubber piston 29 is much smaller than the diameter of the water-blocking rubber piston film 34 of the lower water-blocking rubber piston 31. The water-blocking rubber piston film 34 of the lower water-blocking rubber piston 31 is almost close to the inner wall of the water blocker 27.

[0007] The upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 are separated and overlapped. When water pressure impacts the water-blocking rubber piston film 34, it can play a relative sealing role. After the water supply work stops, under the action of atmospheric pressure, the upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 will droop, allowing the atmosphere to pass through quickly and draining the water in the pipe.

[0008] The zero-cold-water electromagnetic control switch sensor 11 can control the zero-cold-water electromagnetic control switch 1 and the cold water supply solenoid valve 7 to open simultaneously, and the manual cold water switch 6 can be used to adjust the water temperature.

[0009] The present invention relates to a shower water heater controlled by a zero-cold-water control switch in the hot water pipe, which has the following advantages: The zero-cold-water electromagnetic control switch utilizes the principle of atmospheric pressure to drain the hot water from the shower water heater's drain pipe. When showering again, the zero-cold-water electromagnetic control switch is turned on, and hot water directly enters the hot water drain pipe from the water heater's heating tank. This eliminates the need to drain the water from the hot water pipe over a long period of time, thus avoiding water waste. Since there is no water in the hot water pipe, there is no need to worry about the pipe freezing and clogging in winter due to low temperatures. The zero-cold-water control switch can also be used in liquid pipeline transportation. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] A shower water heater controlled by a zero-cold-water control switch inside the hot water pipe. The zero-cold-water electromagnetic control switch 1 has a hot water drain connection pipe 19 connected to the outlet 20 of the electromagnet column housing, which is connected to the hot water drain pipe 5. The zero-cold-water electromagnetic control switch hot water outlet connection pipe 22 is connected to the hot water inlet 21 of the electromagnet column housing, which is connected to the bottom of the water heater heating tank 2. The water heater heating tank 2 has an overflow pipe 3 on the upper right side. The hot water drain pipe 5 is connected to a cold water pipe 4 at the top and a cold water supply pipe 8 at the bottom. A manual cold water switch 6 controls the water flow and cold water supply. Pipe 8 is equipped with a cold water supply solenoid control valve 7. The lower end of the hot water drain pipe 5 is connected to the shower head 10. The water flow is controlled by a manual shower head switch 9. The control circuits of the zero cold water solenoid control switch sensor 11, the zero cold water solenoid control switch 1, and the cold water supply solenoid valve 7 are connected to the fully intelligent water heater controller 12. The spring fixing cover 14 of the zero cold water solenoid control switch 1 is fixed to the outer shell of the coil 16. The spring 13 presses against the electromagnet column 15. When the coil 16 is energized, the electromagnet column 15 is attracted, and the outlet 23 of the electromagnet column coincides with the outlet 20 of the outer shell of the electromagnet column. When the inlet 24 of the magnetic column coincides with the hot water inlet 21 of the electromagnet column housing, the hot water circuit is connected. When the coil 16 of the zero cold water electromagnetic control switch is de-energized, the electromagnet column 15, under the action of the spring force, has its air outlet 26 coinciding with the water outlet 20 of the electromagnet column housing, and its other end coinciding with the air inlet 18 of the electromagnet column housing. This utilizes atmospheric pressure to empty the water in the hot water drain pipe 5. This emptying of the hot water drain pipe 5 is achieved after showering, by closing the manual cold water switch 6 and opening the manual shower head switch 9. The hot water drain pipe 5 also... The water heater heating tank 2 is responsible for supplying cold water. A water blocker 27 is placed inside the air passage 17 of the electromagnet column. The water blocker 27 has a water blocking cylinder inlet 28 at the top and a crossbar 32 for fixing the piston shaft at the bottom. The two ends of the crossbar are welded to the bottom of the water blocking cylinder. The piston shaft 30 is vertically welded to the middle of the crossbar 32 for fixing the piston shaft. The sliding sleeve 35 of the lower water blocking rubber piston 31 is fitted on the bottom of the piston shaft 30, and the sliding sleeve 35 of the upper water blocking rubber piston 29 is fitted on the top of the piston shaft 30. The upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 are separated and overlapped.

[0021] The energization or de-energization of the zero-cold-water electromagnetic control switch coil 16 is determined by whether the showerer approaches or leaves the zero-cold-water electromagnetic control switch sensor 11. When the showerer approaches the zero-cold-water electromagnetic control switch sensor 11, the zero-cold-water electromagnetic control switch coil 16 is energized; when the showerer leaves the zero-cold-water electromagnetic control switch sensor 11, the zero-cold-water electromagnetic control switch coil 16 is de-energized.

[0022] When a strong water flow impacts the lower water-blocking rubber piston 31, the lower water-blocking rubber piston 31 moves upward, pushing the upper water-blocking rubber piston 29 upward. This causes the upper water-blocking rubber piston head 33 to block the inner opening 28 of the water blocker. Under continuous water pressure, the electromagnet column 15 overcomes the spring force and begins to move upward, causing the outlet 23 of the electromagnet column to coincide with the outlet 20 of the electromagnet column housing, and the inlet 24 of the electromagnet column to coincide with the hot water inlet 21 of the electromagnet column housing. The cold water path is then connected to the heating tank 2 of the water heater. Using the water blocker 27 to fill the water heater heating tank 2 with cold water, the zero cold water electromagnetic control switch 1 can be directly turned on to fill the water heater heating tank 2 with cold water. However, since the water heater heating tank 2 is filled with cold water for a long time without interruption, the coil of the zero cold water electromagnetic control switch 1 is prone to burnout. The diameter of the water-blocking rubber piston film 34 of the upper water-blocking rubber piston 29 is much smaller than the diameter of the water-blocking rubber piston film 34 of the lower water-blocking rubber piston 31. The water-blocking rubber piston film 34 of the lower water-blocking rubber piston 31 is almost close to the inner wall of the water blocker 27.

[0023] The upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 are separated and overlapped. When water pressure impacts the water-blocking rubber piston film 34, it can play a relative sealing role. When the water supply work stops, under the action of atmospheric pressure, the upper overlapping rubber piston film edge 36 and the lower overlapping rubber piston film edge 37 will droop, allowing air to pass through quickly and draining the water in the pipe.

[0024] The zero-cold-water electromagnetic control switch sensor 11 can simultaneously control the zero-cold-water electromagnetic control switch 1 and the cold water supply solenoid valve 7 to close or open, while the manual cold water switch 6 plays the role of adjusting the water temperature.

[0025] The zero-cold-water electromagnetic control switch 1 not only prevents water from entering the hot water pipe, but also eliminates concerns about the water in the hot water pipe freezing and clogging or cracking the pipe. The zero-cold-water electromagnetic control switch 1 can also be applied to pipeline liquid transportation. For shower water heaters where the cold water pipe and hot water pipe are separate and externally connected, a zero-cold-water electromagnetic control switch is also installed on the cold water pipe to prevent freezing.
