Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of close-coupled solar water heater with antifreeze emptying function, and it can thoroughly solve, and water heater is antifreeze, the problem of plug and play.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
a kind of close-coupled solar water heater with antifreeze emptying function, comprise heat storage water tank and water inlet pipe and water outlet pipe, the water inlet pipe and water outlet pipe end arranges hot water outlet, cooling water inlet and the discharge outlet that is used for the emptying water inlet pipe and water outlet pipe, discharge outlet is controlled by draining valve, cooling water inlet is controlled by water supply valve, be arranged in and be located the closure member that opens and closes this mouth of pipe on the water inlet pipe and water outlet pipe mouth of pipe of heat storage water tank inner chamber, communicating pipe is run through closure member up and down, link up heat storage water tank inner cavity top headroom and closure member below water inlet pipe and water outlet pipe communicating pipe, be fixed with on communicating pipe below closure member or closure member to downward-extension and drive rod that can move up and down to drive the closure member keying water inlet pipe and water outlet pipe mouth of pipe, drive rod provides driving force by driving mechanism.
Above-mentioned close-coupled solar water heater, water inlet pipe and water outlet pipe is provided with temperature sensing device, and driving mechanism, temperature sensing device, draining valve and water supply valve all are electrically connected with controller.
Above-mentioned close-coupled solar water heater, top, heat storage water tank side are provided with links up inner chamber and extraneous exhaust outlet, is provided with water-level and water-temperature sensor in exhaust outlet, and water-level and water-temperature sensor and controller are electrically connected.
Above-mentioned close-coupled solar water heater, the water inlet pipe and water outlet pipe of close heat storage water tank are to a side bending so that drive rod stretches out water inlet pipe and water outlet pipe, and driving mechanism is for stretching out with drive rod the electronic or electromagnetic drive mechanism that end is connected.
Above-mentioned close-coupled solar water heater also is set to drive rod and moves up and down the guide of guide effect is provided in water inlet pipe and water outlet pipe.
Under normality, the water inlet pipe and water outlet pipe mouth of pipe is in opening, realizes hot water output or upper water function.When temperature was low, water freezed in the water inlet pipe and water outlet pipe, and under the drive of drive rod, closure member moves down the sealing water inlet pipe and water outlet pipe mouth of pipe, cut-off liquid flow, draining valve action opening water discharge mouth, the water in the emptying water inlet pipe and water outlet pipe.The utility model has been realized the whole emptying of water inlet pipe and water outlet pipe, thoroughly solves the antifreeze problem of water heater, realizes the solar water heater plug and play.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is whole diagram of the present utility model.
Fig. 2 is the schematic diagram that the water inlet pipe and water outlet pipe mouth of pipe is in opening.
Fig. 3 is the schematic diagram that the water inlet pipe and water outlet pipe mouth of pipe is in closed condition.
In figure: 1 heat storage water tank, 2 water inlet pipe and water outlet pipes, 3 draining valves, 4 water supply valves, 5 temperature sensing devices, 6 controllers, 7 exhaust outlets, 8 closure members, 9 communicating pipes, 10 drive rods, 11 driving mechanisms.
The specific embodiment
As Figure 1-3, the close-coupled solar water heater that has an antifreeze emptying function comprises heat storage water tank 1 and water inlet pipe and water outlet pipe 2.The discharge outlet that the water inlet pipe and water outlet pipe end arranges hot water outlet, cooling water inlet and is used for the emptying water inlet pipe and water outlet pipe, discharge outlet is controlled by draining valve 3, and cooling water inlet is controlled by water supply valve 4.Be arranged in and be located the closure member 8 that opens and closes this mouth of pipe on the water inlet pipe and water outlet pipe mouth of pipe of heat storage water tank inner chamber.Communicating pipe 9 is run through closure member up and down, links up heat storage water tank inner cavity top headroom and closure member below water inlet pipe and water outlet pipe communicating pipe, for emptying water inlet pipe and water outlet pipe provides air inlet.Be fixed with on communicating pipe below closure member or closure member to downward-extension and drive rod 10 that can move up and down to drive the closure member keying water inlet pipe and water outlet pipe mouth of pipe, drive rod provides driving force by driving mechanism 11.
