Abstract
The utility model provides an automatic emptying device for solar water heater, mainly comprising a controller and an upper emptying valve and an air hole arranged at the upper part of a water inlet and outlet pipe. The utility model is characterized in that the water inlet and outlet pipe is also provided with a lower emptying valve at the lower part, the upper emptying valve and the lower emptying valve are both electrically controlled valves with electrically controlled ends connected with corresponding output control ends of the controller respectively; a temperature sensor is arranged inside or at the outer wall of the pipeline between the upper emptying valve and the lower emptying valve and an output end of the temperature sensor is connected with an temperature detection interface. During actual operation, the controller of the utility model is capable of making an judgment according to the temperature signal transmitted from the temperature sensor, if the temperature of the pipeline is too low and close to the freezing point, the controller gives a command to turn off the upper emptying valve, turn on the lower emptying valve, and then empty the pipeline automatically with no need for manual intervention during the whole course, realizing the actual automatic emptying.
Description
Technical field:
The utility model belongs to the solar water heater field of intelligent control technology, refers more particularly to automatic emptying technology.
Background technology:
Find that according to the investigation to solar water heater product and user on the present market solar water heater product uses still very inconvenience at present, what wherein bother most is the antifreeze problem in winter.If there is not antifreeze function, so in winter, water pipe often takes place freeze and can't use, even the bursting by freezing water pipe.At this problem, occurred adopting the technology of water in the emptying water pipe to reach antifreeze purpose on the market, as the patent No. be ZL98227989 and ZL00221021 Chinese patent disclosed water pipe emptying technology and the device can be antifreeze preferably, but all need manual operation, in winter of cold if the user once forget the water in the emptying water pipe behind last water or after using up hot water and freeze, so just might solar water heater can not be do not used because of ducted ice does not melt, still good effect can not be reached in whole winter.
Summary of the invention:
The purpose of this utility model is to provide a kind of manual intervention that need not, and can realize the solar water heater emptier of automatic emptying according to variations in temperature.
The purpose of this utility model is achieved through the following technical solutions: automatic emptying device for solar water heater, mainly comprise controller, be positioned at last exhaust-valve, the passage on water inlet pipe and water outlet pipe top, it is characterized in that: the bottom at water inlet pipe and water outlet pipe also is provided with exhaust-valve, last exhaust-valve and following exhaust-valve are electrically-controlled valve, and their automatically controlled end is connected with the corresponding control output end of controller respectively; Pipe interior or pipeline outer wall between last exhaust-valve and following exhaust-valve are provided with temperature sensor, and the output of temperature sensor is connected with the temperature detection interface of controller.
The utility model in actual use, its controller can judge according to the temperature signal that temperature sensor transmitted, and crosses lowly during near freezing point when pipe temperature, controller sends instruction, closes to close exhaust-valve, opens down exhaust-valve, automatic emptying pipe; Need not manual intervention, realized real automatic emptying.
Description of drawings:
Fig. 1 is the mounting structure schematic diagram of the utility model in solar water heater.
1 is that water tank, 2 is that controller, 3 is that temperature sensor, 4 is that water intaking valve, 5 is that exhaust-valve, 6 is that delivery port, 7 is that pipeline, 8 is that last exhaust-valve, 9 is a passage down.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
As seen from Figure 1, automatic emptying device for solar water heater, mainly comprise controller 2, be positioned at the last exhaust-valve 8 on water inlet pipe and water outlet pipe 7 tops, the passage 9 that is communicated with water inlet pipe and water outlet pipe 7, it is characterized in that: exhaust-valve 5 once also is set in the bottom of water inlet pipe and water outlet pipe 7, last exhaust-valve 8 and following exhaust-valve 5 are electrically-controlled valve, and their automatically controlled end is connected with the corresponding control output end of controller 2 respectively; Pipe interior or pipeline outer wall between last exhaust-valve 8 and following exhaust-valve 5 are provided with temperature sensor 3, and the output of temperature sensor 3 is connected with the temperature detection interface of controller 2.It can also be seen that from Fig. 1, passage 9 at least with the gap of water tank 1 in same level height.
Operation principle of the present utility model is: after water tank 1 had advanced water, water intaking valve 4 (manual or automatically controlled) was closed.To detect temperature sensor 3 temperature low excessively when controller 2, during near freezing point, then send instruction, exhaust-valve 8 is closed in the pass, make the water in the water tank 1 can not be toward dirty, open down exhaust-valve 5 simultaneously or after time-delay a period of time, air enters pipeline 7 from blow vent 9, and the water in the pipeline 7 is discharged to the place of user's appointment from following exhaust-valve 5.When the user needs water, only need to send instruction by gauge tap on the controller, close down exhaust-valve 5, open exhaust-valve 8, the water in the water tank 1 will flow out from delivery port 6 through piping 7.
The utility model is simple in structure, evacuation and anti-freezing fully automatically, makes the user can can't not use solar water heater or freezing pipeline because winter forgets emptying again.
