Background
As is well known, when a solar water heater is used, hot water is discharged after the water tap is opened because the water outlet pipeline has the residual water cooled after the solar water heater is used last time. Therefore, on one hand, water sources are wasted, and on the other hand, when the air temperature is reduced to be below the freezing point, the solar water heater cannot be used due to the fact that water in the pipe is frozen, and a water outlet pipeline can be frozen.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the emptying device of the water outlet pipeline of the solar water heater is capable of emptying the water outlet pipeline.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: an emptying device of a water outlet pipeline of a solar water heater comprises: the solar water heater comprises a U-shaped pipe, a gas-water check valve, a gas injection pipeline and a pneumatic pump, wherein one port of the U-shaped pipe is connected with a water outlet of the solar water heater, the other port of the U-shaped pipe is connected with a water inlet of a water outlet pipeline, the water outlet pipeline is connected with one end of the gas injection pipeline through the gas-water check valve, and the other end of the gas injection pipeline is connected with an outlet of the pneumatic pump.
As a preferable scheme, in the emptying device of the water outlet pipeline of the solar water heater, an air pressure safety valve is further arranged on the air injection pipeline.
The gas injection pipeline is provided with a pressure relief pipeline through a tee joint for pressure relief, and the air pressure safety valve is arranged on the pressure relief pipeline.
As a preferable scheme, in the emptying device of the water outlet pipeline of the solar water heater, the water outlet pipeline is connected with a gas-water check valve through a tee joint for gas injection.
As a preferable scheme, in the emptying device of the water outlet pipeline of the solar water heater, the gas injection tee joint is close to a hot water pipe which is connected with the water outlet pipeline and water using terminal equipment in the vertical direction.
The utility model has the advantages that: the utility model discloses a pneumatic pump pours into outlet conduit into compressed air through the gas injection pipeline into, will use behind the solar water heater, remain in outlet conduit during the residual water backward flow to the solar water heater to, after pneumatic pump shuts down, because the existence of U type pipe, water among the solar water heater can not flow in outlet conduit, thereby realized outlet conduit's evacuation, practiced thrift the water resource, and, when temperature drops to below freezing point, also can not freeze out outlet conduit because of the residual water in the pipeline freezes. In addition, due to the arrangement of the air pressure safety valve, the water outlet pipeline can be well protected when being blocked due to abnormity, so that the whole emptying device is safer to use.

Detailed Description
The following describes in detail a specific embodiment of an emptying device for an outlet pipe of a solar water heater according to the present invention with reference to the accompanying drawings 1 and 2:
example 1:
as shown in fig. 1, the emptying device of the water outlet pipeline of the solar water heater of the present invention comprises: u type pipe 1, air water check valve 9, gas injection pipeline 5 and air pressure pump 7, a port of U type pipe 1 links to each other with solar water heater's delivery port (belong to the conventional technique in this field, not shown in the figure), another port of U type pipe 1 passes through coupling 201 and links to each other with the water inlet of outlet pipe way 2, outlet pipe way 2 through the gas injection with tee 23 with the one end of gas injection pipeline 5 and the one end of second hot-water pipe 32 link to each other, the second tap 42 as water end equipment is installed to the other end of second hot-water pipe 32, the other end of gas injection pipeline 5 with the export of air pressure pump 7 links to each other, the cluster is equipped with air water check valve 9 on the gas injection pipeline 5, is provided with pressure release pipeline 61 through tee 6 for the pressure release on this gas injection pipeline 5, is provided with atmospheric pressure relief.
Example 2:
as shown in fig. 2, the emptying device of the solar water heater outlet pipeline comprises two taps, namely a first tap 41 and a second tap 42, the second tap 42 is connected with the outlet pipeline 2 through a second hot water pipe 32, a gas injection tee 23, a connecting pipe 21 and a connecting tee 22, and the other port of the connecting tee 22 is connected with the first tap 41 through a first hot water pipe 31. The other structures are the same as those of embodiment 1, and are not described herein again.
In practical application, the three-way pipe 23 for gas injection is close to the second hot water pipe 32 in the vertical direction, that is: the vertical section of the second hot water pipe 32 should be as short as possible; the pneumatic pump 7 is a miniature direct-current inflator pump, is placed in the silencing box, is started by a contact type button switch, controls the single working time of the miniature direct-current inflator pump by a timer, and is automatically turned off when the working time is up; the silencing box consists of a box body consisting of an upper half box and a lower half box and silencing cotton arranged in the box body, and the box body is provided with an air suction hole.
