Abstract

The utility model relates to an anti-freezing device of a solar water heater. The anti-freezing device of a solar water heater comprises a lower water collecting pipe of a solar heat collector and an electric heater. The utility model is characterized in that an electric heating rod in which a temperature sensor and an electric heater are arranged is arranged in the lower water collecting pipe of the solar heat collector. An end plug connected with the electric heating rod into a whole body is arranged at the end of the lower water collecting pipe of the solar heat collector. A power supply connector electrically connected with the electric heater and the temperature sensor in the electric heating rod is arranged in a user room. Frosting can be effectively prevented. The anti-freezing device can be rapidly detected for operation in the condition that the user is not required to go out. The utility model which is the ideal anti-freezing device for a solar water heater has the advantages of simple structure, reliable operation, less power consumption, low cost, convenient operation, etc.

Description

The solar water heater defroster

The utility model relates to a kind of defroster, especially a kind of defroster that is used on the solar water heater.

Extremely people's welcomes of characteristics such as solar water heater is energy-conservation, easy to use, simple in structure with it, low price especially are widely used in the more area of solar radiation.But because solar water heater all places open-air work, and used material is thin, and dress water within it can not once use up, and therefore, when running into Winter-Spring cold current surprise attack, can freeze rapidly in the short time, thereby cause the water heater bursting by freezing to damage and unrenewable.The arrival of this sudden cold current very easily causes the large tracts of land of solar water heater to damage, and the difficulty of its reparation is well imagined.Comparatively effectively antifreezing measures are exactly with the water emptying in the solar water heater at present, and obvious this method will be wasted precious water resource, and very inconvenience of emptying operation, therefore, are necessary prior solar water heater is improved.

The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of efficient, reliable, simple in structure, easy to use, energy consumption is low and have the solar water heater automatic freezing-protective device of measuring ability.

The utility model is finished by following technical proposal: it comprises collector pipe and electric heater under the solar thermal collector, it is characterized in that under heat collector, being provided with in the collector pipe electrically heated rod that temperature detector and electric heater are housed in it, the collector pipe end is provided with the plug that is connected as a single entity with electrically heated rod under heat collector, the user indoor be provided with electrically heated rod in electric heater and the connector device that is electrically connected of temperature controller.

Described Electric heating bar is that an elongated hollow cylinder is held in both hands or square column is held in both hands, the sealing of one end, and the other end and plug are connected as a single entity, and in the hollow bar barred body electric heater are set.

Described plug is the hollow cylinder of a band boss, its boss end and heating rod are connected as a single entity, other end sealing is provided with temperature detector and electric connection line in the plug body, so that on the switch that allows the electric connection line of electric heater and temperature controller pass this plug to be connected to the connector device respectively, indicator lamp.

Described connector device is an attaching plug, which is provided with path monitoring indicator lamp 9, burner on light 10 and sense switch 11, and is electrically connected with heater, temperature detector respectively.

The utility model compared with prior art has following advantage and effect: owing to be provided with automatic heater in the collector pipe under heat collector, therefore can effectively prevent freezing, whether guarantee the working properly of solar water heater, this device also is provided with detector in addition, make the user not go out the family and can detect defroster rapidly and can work, this device also has simple in structure, reliable operation, little power consumption, cost is low, therefore characteristics such as easy to use are a kind of comparatively desirable solar water heater defrosters.

Fig. 1 is the heating rod and the plug structure chart of the utility model;

Fig. 2 is the connector device structure chart of the utility model;

Fig. 3 is the circuit structure diagram of the utility model.

Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.

Fig. 1, among Fig. 2,1 is the heating rod barred body, it is an elongated hollow cylinder, the sealing of one end, the other end and plug 5 are connected as a single entity, this heating rod barred body places in the following collector pipe 2 of solar thermal collector, and being provided with

heater

3,4 in the barred body 1 is the probe of temperature detector, place water, and be electrically connected with temperature detector 6 by lead, 5 is plug, is the hollow cylinder of a band boss, the end of boss and heating rod 1 are connected as a single entity, and place down collector pipe 2 ends, be provided with temperature detector 6 and electric wire 7 in it, its end 14 sealings, 8 is the connector device, be attaching plug, path monitoring indicator lamp 9 is set on it, burner on light 10, sense switch 11, by electric wire 7 respectively with heating rod in heater 3 and the temperature detector 6 in the plug be electrically connected.

Among Fig. 3, heater 3 one ends are connected to positive source by temperature detector 6 (being temperature detect switch (TDS)), and the other end is connected to power cathode; Path monitoring indicator lamp 9 one ends link to each other with burner on light 10 1 ends, the other end links to each other with positive source by resistance 12, the other end of burner on light 10 links to each other with power cathode by resistance 13, and sense switch 11 1 termination power positive poles, the other end are connected to a point and b point respectively.

Its course of work is: when water temperature during above zero, package unit is not worked.When water temperature during near zero degree, temperature detector 6 auto-closings are connected heater 3 work, when water temperature reaches 5-8 and spends, and the heating of temperature detector 6 automatic disconnection stops, the water freezing in heating can prevent to manage so repeatedly.Because this device is except that winter, be in off working state for a long time in spring, summer, autumn, therefore can detect by sense switch 11, promptly press sense switch 11 (it is a normally opened contact), electric current forms the loop through positive pole, sense switch 11, heater 3, negative pole, and electric current also forms the loop through positive pole, sense switch 11, burner on light 10, resistance 13, negative pole simultaneously, and 10 light, show that device is working properly, sense switch return (disconnection) when letting go.Because path monitoring indicator lamp 9 is a neon tube, when temperature detector 6 is not worked, only there is monitoring current to form the loop, therefore not power consumption through resistance 12, path monitoring indicator lamp 9, heater 3.
