Abstract

The utility model relates to a water heater which is used for keeping water temperature in a water tank of a solar water heater constant. The utility model comprises supporting frames, a heat collector and a water storage tank. The utility model is characterized in that inside sliding tracks are respectively fixed on the oblique supporting frames at both sides of the heat collector. A rotating shaft is fixed between the upper part of the heat collector and the position which approaches to the lower part of the water storage tank, and a shading cloth is wound outside the rotating shaft. The lower part of the shading cloth is fixedly provided with a transverse rod, and both ends of the transverse rod are inserted into the sliding tracks at both sides and are matched with the sliding tracks in a sliding way. One end of the rotating shaft is fixedly connected with a two-way motor, and a motor control circuit is composed of a temperature sensor, a trigger switch and a temperature controller. After the solar water heater adopts the proposal, the constancy of the temperature of a water storage cylinder can be realized by controlling light irradiation time. The utility model has the advantages of direct hot water use, long service life and water saving.

Description

The automatic constant-temperature solar water heater

One, technical field: the utility model relates to a kind of solar water heater, and the water temperature in particularly a kind of water tank that can make solar water heater keeps constant water heater.

Two, background technology: at present, solar water heater adopts the vacuum absorption solar heat that water temperature is improved, and the water temperature in the water tank is high and low can not regulate.Particularly summer solar water heater be subjected to light application time, intensity effect, cause water temperature too high, hot water can not directly use, and need to rely on outlet pipe to be connected with running water, the height of water temperature is regulated in the unlatching of dependence valve; In addition for a long time temperatures involved the service life of vacuum tube and water storage cylinder and pipeline; If do not use the water in the water tank, solar water heater heats always, and water evaporates always, and the water yield reduces.

Three, summary of the invention: in order to overcome the deficiency that solar water heater water-temperature can not be regulated, the utility model provides a kind of constant relatively solar water heater of water tank water temperature that keeps.

The utility model comprises bearing support, heat collector and storage tank are formed, it is characterized in that: on the tilted supporter of heat collector both sides, be fixed with inboard slide rail respectively, top at heat collector is fixed with rotating shaft near between the storage tank bottom, gobo is twined in rotating shaft outward, the gobo bottom is fixed with cross bar, insert in the slide rail of both sides at the two ends of cross bar, and slide cooperation with it, the fixedly connected either-rotation motor of an end in rotating shaft, temperature sensor is housed in storage tank, on slide rail, the bottom is fixed with trigger switch respectively, trigger switch touches with cross bar and cooperates, temperature sensor, trigger switch and temperature controller are formed circuit for controlling motor, are with sheath outside the gobo in rotating shaft.

Improvement project of the present utility model is that motor is fixed near on the bearing support of storage tank lower end, be fixedly connected with recessed the wheel on the motor output shaft, the recessed wheel is fixed with stay cord, the other end of stay cord is connected with cross bar, end in rotating shaft is fixed with helical spring, near in the slide rail of lower end electromagnetic switch is being housed, a protruding axle is being arranged on the electromagnetic switch, cooperating with cross bar.

Solar water heater behind the employing such scheme, the temperature of the temperature sensor by setting water storage cylinder, drive the control of gobo enforcement by the temperature-control circuit drive motors to heat collector illumination, realize the constant of water storage cylinder temperature by the control light application time, have direct use hot water, increase the service life, water-saving effect.

Fig. 2 is the three-dimensional structure diagram of another embodiment of the utility model;

Fig. 3 is the structure chart of rotating shaft and jacket portions;

Fig. 4 is a kind of control circuit schematic diagram.

Five, the specific embodiment:

Embodiment 1: contrast accompanying drawing 1 and 3, water heater comprise bearing support 4, heat collector (vacuum tube) 7 and storage tank 1 composition.Be fixed with inboard slide rail 3 respectively on the tilted supporter of heat collector 7 both sides, be fixed with rotating shaft 12 on the top of heat collector near between the storage tank bottom, the rotating shaft 12 outer gobos 2 that twine are with sheath 5 outside the gobo 2 in rotating shaft 12.Gobo 2 bottoms are fixed with cross bar 6, and insert in the slide rail 3 of both sides at the two ends of cross bar 6, and slide cooperation with it.At the fixedly connected either-rotation motor 10 of an end of rotating shaft.Contrast Fig. 4, temperature sensor WT is housed in storage tank 1, upper and lower end portion at slide rail 3 is fixed with trigger switch Lmax and Lmin respectively, temperature sensor WT and relay J 1, J2 form temperature controller, design temperature adjusting range Tman and Tmix, trigger switch Lmax and Lmin touch with cross bar 6 and cooperate.

Embodiment 2:

contrast accompanying drawing

2 and 3, on the basis of embodiment 1, motor 10 is fixed near on the bearing support 4 of heat collector 7 lower ends, be fixedly connected with on motor 10 output shafts and recessedly take turns 9, the recessed wheel is fixed with stay cord 11 on 9, the other end of stay cord 11 is connected with cross bar 6, is fixed with helical spring 13 in the end of rotating shaft 12.Near in the slide rail of lower end electromagnetic switch (not drawing among the figure) is being housed, a protruding axle is being arranged on the electromagnetic switch, cooperating with cross bar cross bar is locked.Its control circuit just will be controlled the output of motor counter-rotating with reference to Fig. 4, be connected on the electromagnetic switch, realize the locking and the release of cross bar by the control electromagnetic switch is charged with cutting off the power supply.
