Problems solved by technology

[0002] At present, there is a certain distance between the water outlet and the nozzle of the water heater in use, especially the domestic gas water heater often uses a longer pipeline for safety reasons, so it is necessary to drain the cold water in the pipeline during use. It can only be used after the hot water comes out, which causes a lot of waste of water resources and inconvenience in use. The current solution is to lay double pipes and add a circulation pump to the water heater at the same time to heat and circulate the cold water in the pipes. When the water temperature in the pipeline reaches the set requirements, the solenoid valve is controlled by the thermostat to supply water to the nozzle. The second is to install an electric heater in front of the water outlet control valve to heat the cold water in the pipeline and flow out of the nozzle. In the above two schemes, the use of pipelines, circulating pumps, thermostats and solenoid valves in the former increases the manufacturing cost, and at the same time requires high reliability of the circulating pumps, thermostats and solenoid valves used. There are certain safety hazards in the use of electric heating everywhere, and it also makes the structure complicated. Is there a way to solve the above problems that does not require electric heating, laying pipelines, and adding more additional equipment? At the same time, it must be guaranteed The user's safety and simple operation, it is best not to affect the structure of the existing water heater, which needs to be considered from the use terminal of the water heater. As easy as possible

Embodiment 1

[0045] Embodiment 1: In this embodiment, the switching valve (5) is a three-position valve, one water inlet and three water outlets, and one water outlet is the hand-held water outlet (7) to the hand-held shower head (12) through the hand-held water pipe (9), The other two water outlets are respectively through the water storage pipe (16) to the water storage cylinder (8) and through the fixed water pipe (23) to the fixed nozzle (13). The water storage cylinder (8) is a transparent cylinder with Water level scale.

[0046] Such as figure 1 and figure 2 As shown, the hot and cold water regulating valve (2) is provided with a water inlet pipe (1) and a hot and cold water regulating handle (3), and its regulating valve outlet (14) is connected with the switching valve water inlet (4). 5) There is a switching valve core (15) inside, a switching handle (6) is provided on one side of the switching valve (5), and a hand-held water outlet (7) is provided on the other side, and the ...

Embodiment 2

[0050] Embodiment 2: In this embodiment, the switching valve (5) is a two-position valve, with one water inlet and two water outlets, and the two water outlets are respectively connected to the water storage pipe (16) and the fixed water pipe (23).

[0051] Such as Figure 6-1 As shown, in the water storage state, the switching handle (6) is placed in the horizontal position, the fixed water outlet channel (25) on the switching valve core (15) is in the closed state, the water storage channel (24) is in the connected state, and the water passes through the water storage Passage (24) to water storage tube (8) through the water storage hole (18) on the water storage pipe (16), when the water level in the water storage tube (8) was low, the float ball (22) and the float ball rod (21) is in the low position by self weight, and now the limit baffle (27) on the top of the floating ball (22) covers the water outlet of the fixed water pipe (23), and the siphon hole A (17) and the wate...

Embodiment 3

[0053] Embodiment 3: In this embodiment, the switching valve (5) is a two-position valve, one water inlet and two water outlets, and the two water outlets are respectively connected to the water storage pipe (16) and the fixed water pipe (23), and the water storage pipe ( 16) Isolated from the fixed water pipe (23), the length of the fixed sleeve (19) on the water storage tube (8) equals the height of the water storage tube (8), and the length of the fixed water tube (23) is higher than the water storage tube (8) ), the fixed connection water pipe (10) is arranged on the fixed water pipe (23).

[0054] Such as Figure 7-1 As shown, under the water storage state, the switching handle (6) is placed in a horizontal position, the fixed water outlet channel (25) is in a closed state, the water storage channel (24) is connected, and water passes through the water storage channel (24) through the water storage pipe ( 16) to the water storage tube (8) from the water storage hole (18)...

Abstract

A water heater pipeline cold water remover comprises a cold water and hot water regulating valve and a switching valve. A water storage pipe and a fixed water pipe are connected to a water outlet of the switching valve. A water storage cylinder is connected with a fixed casing. The water storage pipe is communicated with the water storage cylinder through a storage hole and a siphoning hole in the water storage pipe. An automatic water outlet is arranged between the water storage pipe and the fixed water pipe. A floater is connected to the fixed water pipe in a sleeving manner. The lower end of a floater rod is provided with a floater spool inserted into the water storage pipe. The top of the floater rod is provided with a limit baffle disposed on a water outlet of the fixed water pipe. The position of the switching valve is changed. A water outlet of the cold water and hot water regulating valve is respectively communicated with the water storage pipe and the fixed water pipe. According to the technical scheme, cold water in a pipeline is stored with the water storage cylinder, the storage hole is automatically closed through the floater spool, and the automatic water outlet is opened to supply water to a fixed nozzle; during the process, the water in the water storage cylinder is pumped away through the siphoning hole; after the cycle goes on, the cold water stored in the water heater pipeline can be effectively removed, water resources are saved, and conveniences for actual use are achieved.
