Description

A kind of multi-functional water heater's switch

Technical field the utility model relates to the heater switch, especially refers to a kind of multi-functional water heater's switch.

The widely used in the market heater switch of technical background is an electronic type, especially with the heater switch of PCU Power Conditioning Unit, all is made up of electronic devices and components.The main defective of electronic type heater switch is that energy consumption is big, and heater switch's cost in resistance easy warming-up effect life-span, particularly charged sensing unit is higher, meeting produces noise.And in recent years, the mechanical type heater switch who develops on the market as shown in Figure 1, when current pass through, because siphonage, rubber tissue 4 is down inhaled, and drives bar 601 and moves down, be fixed on contact 602 on the bar 601 and leave the contact 3011 of microswitch 301, the heater switch connects.Though this structure power saving, the function of not regulating power can't satisfy people because of reasons such as climate change or use needs, and the expectation water heater has the convenient needs of regulating power device.

Summary of the invention main purpose of the present utility model provides a kind of employing frame for movement, and multi-functional water heater's switch of power regulatory function is arranged.

The purpose of this utility model can realize by following structure: the heater switch is provided with base, middle frame and puts on the shelf, base is provided with water inlet, in set up refluxing opening and locating hole, put on the shelf and be provided with three above microswitches, be provided with rubber tissue between base and the middle frame, the rubber tissue center fixation push rod, the locating hole of frame during push rod passes, wherein be arranged with the power adjusting plate on the push rod, be arranged with spring and power regulating switch on the spring reference column of power adjusting plate, the switch contact of microswitch is around the central distribution of power regulating switch and corresponding with the power adjusting plate.

The utility model adopts above frame for movement, utilizes the power adjusting plate, when realizing heater switch's control, have the power adjusting function again, and the heater switch switches on just when having current to pass through, therefore have energy efficient, safe in utilization, characteristics such as long service life.

Now the utility model is described in further detail in conjunction with the accompanying drawings for description of drawings:

Fig. 1 is existing machinery formula heater switch's a structural representation;

Fig. 2 is a sectional structure schematic diagram of the present utility model;

Fig. 3 is power regulating switch of the present utility model microswitch contact relative power adjustable plate position view when being in first grade.

Fig. 4 is power regulating switch of the present utility model microswitch contact relative power adjustable plate position view when being in second grade.

Fig. 5 is power regulating switch of the present utility model microswitch contact relative power adjustable plate position view when being in third gear.

Fig. 6 is power regulating switch of the present utility model microswitch contact relative power adjustable plate position view when being in fourth speed.

The specific embodiment is shown in Fig. 2,3, the utility model heater switch is provided with base 1, middle frame 2 and puts 3 on the shelf, base 1 is provided with water inlet 101, middle frame 2 is provided with the locating hole 201 of refluxing opening 203 and push rod 5, the locating hole 202 of power adjusting plate 6, water inlet 101 and refluxing opening 203 communicate with pressure limiting pipe 9, water inlet 101 leads to the large diameter chamber 901 of pressure limiting pipe 9, and refluxing opening 203 leads to the little internal diameter chamber 902 of pressure limiting pipe 9.Be provided with rubber tissue 4 between base 1 and the middle frame 2, be divided into cavity of resorption 401 and epicoele 402 by rubber tissue 4, be fixed with push rod 5 in the rubber tissue 4 in the heart, push rod 5 passes locating hole 201, push rod is provided with power adjusting plate 6, power adjusting plate 6 is set in the locating hole 202, is arranged with spring 7 and power regulating switch 8 on the spring reference column 601 of its projection.Put on the shelf and 3 be provided with three above microswitches 301,302,303, and be set on the power regulating switch 8, switch

contact

3011,3021,3031 on the microswitch 301,302,303 is around the distribution straggly of the center of power regulating switch 8, and corresponding power adjusting plate 6 is provided with groove 602,603 and convex 604,605.

When the water heater water flow switch is opened, current enter pressure limiting pipe 9 large diameter chambeies 901, since current from large diameter chamber 901 to little internal diameter chamber 902, internal diameter dwindles, hydraulic pressure increases suddenly, and current enter the water inlet 101 of base 1 under pressure, to rubber tissue 4 cavity of resorptions 401, water flow jets in the while little internal diameter chamber 902, produce siphonage, with the air sucking-off in rubber tissue 4 epicoeles 402, rubber tissue 4 is with push rod 5 jack-up, push rod 5 jack-up power adjusting plates 6, at this moment, microswitch 301,302, switch contact 3011 on 303,3021,3031 drop on the groove 602 of power adjusting plate 6, in 603, heater switch's access failure, be first grade this moment, and power is 0; When power regulating switch 8 rotations one angle, the switch contact 3031 on the microswitch 303 is by convex 605 jack-up, and water heater power supply is partly connected, and be second grade this moment, and power is about 1800W; When power regulating switch 8 rotates an angle again, the

switch contact

3011,3031 on the microswitch 301,303 is by convex 605 jack-up, and water heater power supply is most of to be connected, and be third gear this moment, and power is about 3000W; When power regulating switch 8 rotates an angle again again, switch

contact

3011,3031 on the microswitch 301,302,303 is by convex 605 jack-up, switch contact 3021 on the microswitch 302 by 1 by convex 604 jack-up, water heater power supply all divides connection, be fourth speed this moment, and power is about 4000W.The utility model so starts the heater switch and realizes power adjusting.
