Abstract
The utility model provides a flow-control dry combustion preventing electric water heater, which comprises an upper seat body, a lower seat body, a current electric heater arranged between the upper and the lower seat body, a manual temperature switch and an automatic temperature switch both assembled on the upper seat body and a water inlet pore arranged on the inner side of the lower seat body, wherein a groove is arranged on the lower seat body of the water inlet pore side, the blade wheels arranged in the groove are movably connected with the both sides of the groove through a rotation shaft, the upper outer rims of the blade wheels project compared with the inner surface of the lower seat body, the bottom of the groove outside is equipped with a photoelectric detecting head used for measuring the rotation speed of the blade wheels. The utility model has the advantages of high sensibility and good dry combustion preventing effect.
Description
Technical field
The utility model relates to a kind of electric heater, refers in particular to a kind of electric heater with the flow-control anti-dry.
Background technology
Chinese patent CN03223068.0 (notification number CN2599463; January 14 2004 day for announcing) a kind of " water flow control slit current electric heater unit " disclosed; be to utilize at delivery port the purpose that one rotation impeller drives a cam and touch-pressure switch interlock realization anti-dry is set; find in actual the use; the sensitivity of this control mode control is relatively poor; particularly when having air to enter in the water pipe, can not play the protection purpose of anti-dry.
Summary of the invention
The utility model is the deficiency at above-mentioned technology, and a kind of electric heater of highly sensitive, band flow-control anti-dry that anti-dry is effective is provided.
The purpose of this utility model is achieved in that a kind of electric heater with the flow-control anti-dry, comprise upper pedestal, lower base, be arranged on the slot-shaped current electric heater between the upper and lower pedestal, be installed in manual temperature switch and automatic temperature-adjusting switch on the upper pedestal, and be arranged on the water inlet pore of lower base inboard, wherein: the lower base of described water inlet pore side is provided with groove, in groove, be provided with impeller, impeller flexibly connects by the two side of rotating shaft and groove, and the top outer rim of this impeller protrudes in the inner surface of lower base; Bottom outside at groove is provided with the Photoelectric Detection head of measuring wheel speed.
Photoelectric Detection head described in the electric heater of above-mentioned band flow-control anti-dry can adopt infrared ray photoelectricity counter switch.
After the utility model adopts said structure, by on the lower base of water inlet pore side, groove being set, and in groove, impeller is installed, is utilized the Photoelectric Detection head that is arranged on the bottom portion of groove outside to detect the rotating speed of impeller, can measure flow of inlet water accurately, prevent dry combustion method effectively; Simultaneously, the water in the groove can increase the rotary resistance of impeller when air enters, and prevents that maloperation from taking place, and more effectively prevents the water heater dry combustion method; And adopting impeller control, the rotating speed of impeller is directly proportional with discharge, and is irrelevant with hydraulic pressure, thereby can use under low hydraulic pressure environment.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Among the figure: 1-upper pedestal, 2-lower base, 21-water inlet pore, 22-groove, 3-current electric heater, the manual temperature switch of 4-, 5-automatic temperature-adjusting switch, 6-impeller, 7-rotating shaft, 8-Photoelectric Detection head.
The specific embodiment
Consult shown in Figure 1, the electric heater of band flow-control anti-dry of the present utility model, comprise upper pedestal 1, lower base 2, be arranged on upper pedestal 1, slot-shaped current electric heater 3 between the lower base 2, be installed in manual temperature switch 4 and automatic temperature-adjusting switch 5 on the upper pedestal 1, and be arranged on the water inlet pore 21 of lower base 2 inboards, on the lower base 2 of water inlet pore 21 sides, be provided with groove 22, in groove 22, be provided with impeller 6, impeller 6 flexibly connects by the two side of rotating shaft 7 with groove 22, the top outer rim of this impeller 6 protrudes in the inner surface of lower base 2, and when current enter, but impeller 6 is rotated; Be provided with the Photoelectric Detection 8 of measuring impeller 6 rotating speeds in the bottom outside of groove 22, this Photoelectric Detection 8 is an infrared ray photoelectricity counter switch.
When the utility model specifically used, current entered from water inlet pore 21, impacted impeller 6 and rotated, and when being the rotating speed of 2L/min as if Photoelectric Detection 8 rotating speed that detect impeller 6 above flow, slot-shaped current electric heater 3 is worked and water is heated; When Photoelectric Detection 8 rotating speed that detect impeller 6 were lower than flow and are the rotating speed of 2L/min, slot-shaped current electric heater 3 was not worked, and prevents dry combustion method.
