Abstract
The utility model relates to a gas water heater capable of automatically preventing frost cracking, which comprises an operation panel, a gas water heater, a gas pipe, a water inlet pipe, a hot water outlet pipe and a remained water discharge pipe, wherein the gas pipe, the water inlet pipe, the hot water outlet pipe and the remained water discharge pipe are respectively connected with the water heater. The utility model is characterized in that an electromagnetic water inlet valve and an electromagnetic water discharge valve which are linked are respectively arranged on the water inlet pipe and the remained water discharge pipe, and the electromagnetic water inlet valve and the electromagnetic water discharge valve are always in a state that one valve is closed and the other valve is opened. Through opening the electromagnetic water inlet valve to control the water inlet, the utility model can control that the water filling begins only when a gas water heater body begins to be used, at the time, the electromagnetic water discharge valve is closed, the gas water heater normally works, after the gas water heater is used, the electromagnetic water inlet valve is closed for stopping the water inlet, at the same time, the electromagnetic water discharge valve is opened for carrying out water discharge to fully discharge the remained water in the gas water heater, and the goal of preventing the frost cracking can be reached. At the same time, the water discharge can be automatically carried out only through stopping the water inlet, the operation is convenient, in addition, the internal body structure of the gas water heater does not need to be changed, and the utility model has the advantages of simple structure and easy processing.
Description
Technical field
The utility model relates to the gas heater technical field, but the gas heater that especially a kind of automatic freezing-protective splits belongs to the improvement of existing gas heater technology.
Background technology
Gas heater can have Yu Shui in water heater inside after finish using, when outside air temperature is crossed when low, thereby can make its volumetric expansion of surplus water freezing make gas heater by bursting by freezing.The prevention bursting by freezing is a more scabrous problem in the gas heater technical field always.The way that solves mainly contains two kinds at present: a kind of is requirement user draining after using gas heater, owing to will turn on the draining valve draining, the user forgets draining easily and causes bursting by freezing; Another kind of is to adorn heater on copper pipe, but owing to the reason of temperature-sensitive or installation site causes losing efficacy easily.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, but the gas heater that provides a kind of automatic freezing-protective to split carries out automatic draining when the user uses the back to shut down, do not need to operate in addition for carrying out draining, and the influence that is not also had a power failure, easy to operate.Gas heater main frame wherein can be all gas heaters that use forceful electric power, need not change its inside subject structure.
The technical scheme that realizes the utility model purpose is: the utility model comprises operation panel, gas heater, the Gas Pipe that is connected with water heater respectively, water inlet pipe, hot water outlet pipe and Yu Shui drainpipe, it is characterized in that on water inlet pipe and Yu Shui drainpipe, being respectively equipped with the electromagnetic water inlet valve and the electromagnetism draining valve of interlock, electromagnetic water inlet valve and electromagnetism draining valve are in one of them all the time and close the state that another is opened.
Aforesaid operations plate and electromagnetic water inlet valve and electromagnetism draining valve can be wired connections, also can be wireless connections.
The beneficial effects of the utility model are: close the state that another is opened because electromagnetic water inlet valve and electromagnetism draining valve are in one of them all the time; Can make the gas heater body when bringing into use, just begin water-filling by opening electromagnetic water inlet valve control water inlet, at this moment, the electromagnetism drain shut valve, the gas heater operate as normal, when use finishing, electromagnetic water inlet valve is closed when stopping into water, and the electromagnetism draining valve is opened and carried out draining, surplus water in the gas heater is drained, reach the purpose of anti-bursting by freezing; Only need stop into water simultaneously, draining is promptly carried out automatically, and is easy to operate; And need not change gas heater inside subject structure.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises operation panel 8, gas heater 7, the Gas Pipe 3 that is connected with water heater 7 respectively, water inlet pipe 1, hot water outlet pipe 6 and Yu Shui drainpipe 4, it is characterized in that on water inlet pipe 1 and Yu Shui drainpipe 4, being respectively equipped with the electromagnetic water inlet valve 2 and the electromagnetism draining valve 5 of interlock, electromagnetic water inlet valve 2 and electromagnetism draining valve 5 are in one of them all the time and close the state that another is opened.
In the time will using hot water, the startup button of start-up operation plate 8, electromagnetic water inlet valve 2 is opened, electromagnetism draining valve 5 cuts out simultaneously, and cold water enters gas heater 7 through water inlet pipe 1, electromagnetic water inlet valve 2, and gas heater 7 starts, to the cold water heating that enters, hot water flows out for using through hot water outlet pipe 6; In the time will stopping using hot water, the stopping key of start-up operation plate 8, electromagnetic water inlet valve 2 is closed, cold water stops to enter gas heater 7, gas heater 7 cuts out and stops heating, and electromagnetism draining valve 5 is opened simultaneously, and the surplus water in the gas heater 7 flows out gas heater 7 through drainpipe 4.Because of after gas heater 7 stops using, gas heater 7 was both anhydrous to be entered, and surplus water is discharged again, and water service pipes just can be because of the low surplus water freezing bursting by freezing of environment temperature in the gas heater 7.
Claims (2)
1. but gas heater that automatic freezing-protective splits, comprise operation panel (8), gas heater (7), the Gas Pipe (3) that is connected with water heater (7) respectively, water inlet pipe (1), hot water outlet pipe (6) and surplus water drainpipe (4), it is characterized in that on water inlet pipe (1) and surplus water drainpipe (4), being respectively equipped with the electromagnetic water inlet valve (2) and the electromagnetism draining valve (5) of interlock, electromagnetic water inlet valve (2) and electromagnetism draining valve (5) are in one of them all the time and close the state that another is opened.
2. but the gas heater that automatic freezing-protective according to claim 1 splits is characterized in that described operation panel (8) and electromagnetic water inlet valve (2) and electromagnetism draining valve (5) are wired connection or wireless connections.
