A temperature controller is arranged at the periphery of a pipeline of the heat exchanger. The antifreezing device is characterized in that the water inlet pipe is provided with an electric control valve of the water inlet pipe; a valve body is connected with a cold water discharge pipe; and the control end of the valve body is electrically connected with the temperature controller. The antifreezing device can be widely used in the gas water heater, realizes the antifreezing function of the heater, and has simple structure, low cost, safety and reliability and easy implementation.
Description
Technical field
The utility model relates to technical field of water heaters, particularly a kind of defroster of gas instantaneous water heater.
Background technology
At present, existing gas heater is for fear of when weather is colder, particularly in the north, the water in the heat exchanger because of the freezing and expansion of catching a cold with the water pipe spalling of heat exchanger, heater just is installed in gas heater.Common have drainage type, an electrothermal etc., and the thermal efficiency of electrothermal defroster is low, the energy consumption height, and need to continue to heat, keep water and be in certain state of temperature, on the meaning of environmental protection and energy saving, this structure is unfavorable for the environmental protection and energy saving theory of existing main flow gas apparatus.The drainage type defroster is that drainage arrangement is installed in gas heater, but this type of drainage arrangement all adopts mechanical system at present, manually discharge water by the user and to reach antifreeze purpose, use very inconvenient, in case and the user forgets and discharges water, when winter, particularly temperature dropped to subzero, can bring very big inconvenience to people like this because of the water bursting by freezing of water heater the inside.
Summary of the invention
The purpose of this utility model is exactly a kind of not only simple in structure, the convenient but also gas instantaneous water heater defroster of fine qualities of use control that provides for the deficiency that solves prior art.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of gas instantaneous water heater defroster, comprise the water inlet pipe and the outlet pipe that are communicated with the heat exchanger of water heater, the pipeline outer periphery of heat exchanger is equipped with temperature controller, it is characterized in that: the water inlet pipe electrically-controlled valve is installed on the described water inlet pipe, this electrically-controlled valve is connected with row's cold water pipe, and the unlatching of electrically-controlled valve is controlled by temperature controller.
As further specifying of such scheme, described water inlet pipe electrically-controlled valve comprises valve body and spool, valve body is provided with two above water inlets, two above delivery ports and more than one discharge outlet, water inlet pipe connects water inlet, delivery port is provided with the cold water pipe that advances that connects heat exchanger, and row's cold water pipe is connected on the discharge outlet; Spool is provided with connection one water inlet and advances the inlet opening and the apopore of cold water channel and the osculum that is communicated with another delivery port and discharge outlet with a delivery port with formation.
The triggering temperature range of described temperature controller is 0～1 ℃.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts and install a magnetic valve electric-controlled switch additional before the heat exchanger water inlet pipe of gas instantaneous water heater inside, when water temperature in the machine arrives 0～1 ℃, the action of magnetic valve electric-controlled switch, this moment, the magnetic valve water-control switch was closed into cold water channel, the drainage channel of opening simultaneously in the machine is discharged water in the heat exchanger tube, thereby reach the effect of automatic freezing-protective, compared with prior art, effectively avoid the user to neglect and cause water heater winter because of the water bursting by freezing of circulating water pipe the inside.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of gas instantaneous water heater defroster of the utility model, comprise the water inlet pipe 2 and the electrically-controlled valve outlet pipe 3 that are communicated with the heat exchanger 1 of water heater, the pipeline outer periphery of heat exchanger 1 is equipped with temperature controller, the triggering temperature range of this temperature controller is 0～1 ℃, is used to detect the state of temperature of water heater inner conduit, and water inlet pipe electrically-controlled valve 4 is installed on the water inlet pipe 2, this valve body is connected with row's cold water pipe 5, and the control end temperature controller of valve body is electrically connected.In the present embodiment, water inlet pipe electrically-controlled valve 4 comprises valve body and spool, and valve body is provided with two water inlets 6, two delivery ports 7 and one 's discharge outlet 8, and water inlet pipe 2 connects water inlets 6, delivery port 7 is provided with the cold water pipe that advances that connects heat exchanger, and row's cold water pipe 5 is connected on the discharge outlet 7; Spool is provided with connection one water inlet and advances the inlet opening and the apopore of cold water channel and the osculum that is communicated with another delivery port and discharge outlet with a delivery port with formation.
In the use, under the normal condition, cold water is entered in the heat exchanger tube by water inlet pipe, discharges hot water through after the heat exchange by the hot-water outlet pipe; When water temperature in the machine arrives 0～1 ℃, the action of magnetic valve electric-controlled switch, this moment, the magnetic valve electric-controlled switch was closed into cold water channel, and the drainage channel of opening simultaneously in the machine is discharged water in the heat exchanger tube, thereby reaches the effect of automatic freezing-protective.
The utility model is not limited to the foregoing description; as shown in Figure 3; the installation site of described electrically-controlled valve can change as required; the triggering temperature range of described temperature controller can also be provided with wider; any those skilled in the art can do numerous modifications and variations; under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
