Abstract
The invention discloses a water boiler heating protective device which is composed of a floating ball, a transmission connecting rod, an upper microswitch and a lower microswitch. The lower end of the transmission connecting rod is connected with the floating ball. The upper end of the transmission connecting rod is movably fixed to the body of a water boiler through a rotating shaft. The upper microswitch is arranged above an upper transmission rod. The lower microswitch is arranged below the upper transmission rod. The upper microswitch and the lower microswitch are electrically connected with a relay in a water boiler water level control circuit through wires respectively. By the adoption of the technical scheme, the water boiler heating protective device overcomes defects in the prior art, is simple in structure, safe and reliable, effectively prevents inoperation or water-free heating phenomena of the water boiler, and ensures using safety of equipment.
Description
Technical field
The present invention relates to electric water heater for drinking, specifically relate to a kind of boiler heating protecting device.
Background technology
Existing electric water heater for drinking on market, its computer heating control is all controlled by float switch, and water level float switch can produce incrustation scale and occur stuck failure in Long-Time Service, cause float switch effectively can not control the heating work of boiler, boiler is very easily caused not work or anhydrous dry combustion method phenomenon, affect the normal use of boiler, can equipment be burnt out time serious, even produce the serious consequences such as on fire.
Summary of the invention
The object of the present invention is to provide a kind of boiler heating protecting device, this heating protecting device overcomes the deficiencies in the prior art, and structure is simple, safe and reliable, effectively prevent boiler and does not work or anhydrous dry combustion method phenomenon, ensure that the use safety of equipment.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is: a kind of boiler heating protecting device, comprise the ball float being arranged on boiler inside, it is characterized in that: this boiler heating protecting device also comprise be arranged on boiler internal body kinematic link, be fixedly installed on upper microswitch on boiler body and lower microswitch; Described kinematic link is by underdrive bar and upload lever and form, the lower end of underdrive bar is connected with ball float, upper end is flexibly connected by bearing pin with the left end uploading lever through the support be fixed on boiler body, and the right-hand member uploading lever is movably fixed on the body of boiler by rotating shaft; Described upper microswitch is arranged on the top of uploading lever, and lower microswitch is arranged on the below of uploading lever, and upper microswitch is corresponding with the left position uploading lever respectively with the switch contact of lower microswitch; Described upper microswitch and lower microswitch are electrically connected with the relay in boiler water-level control circuit respectively by wire.
In technique scheme, ball float, under low water level or desiccation, controls microswitch by ball float by kinematic link, carrys out control relay work, thus makes the power-off of A.C. contactor magnetic coil, and A.C. contactor disconnects. and boiler quits work.The technical program overcomes the deficiencies in the prior art, and structure is simple, safe and reliable, effectively prevent boiler and does not work or anhydrous dry combustion method phenomenon, ensure that the use safety of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of boiler heating protecting device of the present invention under low water level state;
Fig. 2 is the structural representation of a kind of boiler heating protecting device of the present invention under high water level state.
Detailed description of the invention
Below in conjunction with drawings and Examples, a kind of boiler heating protecting device of the present invention is described in further detail.The accompanying drawing forming the application is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.
From Fig. 1, Fig. 2, a kind of boiler heating protecting device of the present embodiment by be arranged on boiler inside ball float 1, be arranged on boiler internal body kinematic link, be fixedly installed on upper microswitch 2 on boiler body and lower microswitch 3 forms.Kinematic link is by underdrive bar 4 and upload lever 5 and form, the lower end of underdrive bar 4 is fixedly connected with ball float 1, upper end is flexibly connected by bearing pin with the left end uploading lever 5 through the hole on the support 6 be fixed on boiler body, the right-hand member uploading lever 5 is movably fixed on the body of boiler by rotating shaft 7, upper microswitch 2 is fixedly installed on the top of uploading lever 5, lower microswitch 3 is fixedly installed on the below of uploading lever 5, upper microswitch 2 is corresponding with the left position uploading lever 5 respectively with the switch contact of lower microswitch 3, upper microswitch 2 and lower microswitch 3 are electrically connected with the relay in boiler water-level control circuit respectively by wire.The present embodiment normally can show water level after guaranteeing that ball float 1 in use produces incrustation scale, by link transmission, starts or disconnects microswitch, reaching the object that electric water heater for drinking normally works.
In the present embodiment, by rising or the decline of boiler water level inside, ball float 1 controls upper microswitch 2 and lower microswitch 3 by kinematic link, thus controls the action of the relay be electrically connected with upper microswitch 2 and lower microswitch 3 in boiler water-level control circuit.Ball float 1, when low water level state, makes upper microswitch 2 be in off-state by the lever 5 of uploading in kinematic link, the power-off of A.C. contactor magnetic coil, A.C. contactor disconnects, equipment quits work, and makes lower microswitch 3 be in closed condition simultaneously, and water tank starts water inlet.Ball float 1 is when high water level state, and make upper microswitch 2 be in closed condition by the lever 5 of uploading in kinematic link, A.C. contactor magnetic coil obtains electric, A.C. contactor adhesive, equipment starts heating, simultaneously, make lower microswitch 3 be in off-state, water tank stops water inlet.The present embodiment overcomes the deficiencies in the prior art, and structure is simple, safe and reliable, effectively prevent boiler and does not work or anhydrous dry combustion method phenomenon, ensure that the use safety of equipment.
The above; only embodiments of the invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent method change, all still belong in the protection domain of technical solution of the present invention.
