Description
The utility model relates to a kind of electric heating constant temperature controller.
Along with improving constantly of expanding economy and living standards of the people, increasing unit, public place and the family electric water heater of having purchased, insulating pot, electric water boiling bucket, various electric water boilers such as electricity water tank, what these electric water boilers now often adopted is in the bottom thermoelectric heating device to be housed, its front end is the circular metal socket, on a pair of power supply contact screw with heat-generating pipe UNICOM is arranged, afterbody extends heat-generating pipe, energized during use, can the water that the inside installs be heated, as seen its advantage shows and, but its defective is when unmanned guard, easily dryouies water and causes the electrical equipment accident.
The purpose of this utility model is to provide a kind of electric heating constant temperature controller, and it can be directly and the supporting use of above-mentioned thermoelectric heating device, cuts off the electricity supply automatically when water is opened, and when water temperature was lower than setting value, energized continued to heat automatically again, plays insulation effect.
For achieving the above object, the utility model is taked following design proposal: a kind of electric heating constant temperature controller, by heat transfer component, thermal sensing element, be arranged on gauge tap in the container and the attaching plug of extension is formed, container is fastened by ceramic butterfly and ceramic case and forms, outer middle side part ceramic butterfly is provided with the scalariform groove, avris has the through hole that a pair of power supply heater power source contact screw passes, there is the through hole of inserting for fore-set the center, one location otch is arranged on the pottery butterfly outer ring, thermal sensing element places in the groove, and heat conducting element posts the outside ceramic butterfly; The fore-set of gauge tap is through in the central through hole of ceramic butterfly, and its normally closed resilient contact is arranged in the container, and the flexure strip of this normally closed resilient contact is moved the motion in fore-set; Corresponding positions is equipped with positioning convex point on ceramic box box inwall, is equipped with attaching plug and corresponding position and has two for heat-generating pipe connection hole on the section of back, and an attaching plug is by connection sheet and electric heater heating pipe linked hole UNICOM.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 is ceramic butterfly structure master, side view
Fig. 3 is ceramic case structure master, side view
Fig. 4 is a radiator valve circuit theory synoptic diagram
As shown in Figure 1, the utility model mainly by heat transfer component, thermal sensing element, be arranged on gauge tap in the container and the attaching plug 12 of extension is formed, heat transfer component comprises metal shell 1 that is nested with on container and the opening quoit 2 of being close to its wall (slightly opening), and this metalloid can be heat conductivility preferred metal such as aluminium, iron, copper.Thermal sensing element 3 has adopted the bimetallic strip of sphere form height sensitivity, the structure of the ceramic butterfly 4 of container as shown in Figure 2, middle side part has scalariform groove 401 outside it, heat supply photosensitive elements 3, metal washer 9 is inserted, there is through hole 402 center, there is the through hole 403 that the power supply contact screw of 2 power supply well heaters 14 passes the corresponding position on the avris circle, one location otch 404 is arranged on the outer end, the structure of the ceramic case 5 of container is referring to Fig. 3, there is positioning convex point 501 corresponding position on its box wall, during for assembling and ceramic butterfly polarizing slot 404 fastening location are used, on the section 502 of back, two attaching plug holes 503 are arranged, and two power supply well heater heat-generating pipes connect linked hole 504, one attaching plug connects linked hole by link piece 11 with a heat-generating pipe and is communicated with, two height boss 505 are arranged on section 502 inwalls, 506, the fixed contact 6 of normally closed resilient contact is fixed on the high boss 505, be communicated with an intercommunicating pore 504, flexure strip 7 is fixed on the low boss, be communicated with the contact of flexure strip 7 head ends and fixed contact 6 head end contact joinings with an attaching plug hole 503.Wear a fore-set 10 in the central through hole 402 of pottery butterfly, make with ceramic-like materials.Normally closed resilient contact is by fixed contact 6, and moving contact 8 and flexure strip 7 constitute, and are closure state under the normal condition, and flexure strip is moved in the motion of fore-set 10.
Shown in Figure 4 is the circuit theory synoptic diagram of radiator valve
When being used for insulating pot, do not influence it and place on the fire and heat up water, components such as container adopt the ceramic-like heat proof material to make.
When using common socket on the market, make two power supply contact screw short circuits of this product electric heater, insulating trip 12 is arranged in container extension power connection side for avoiding two earth points of its end face.
During use, the power supply contact screw of former electric heater is directly passed the through hole 403 of ceramic dish, both can use behind the supporting location.
This radiator valve is contained in the electrothermal tube that has the circular metal seat, by temperature control do power supply switching switch with, therefore play the constant temperature purpose.Be specially adapted to electric water heater, insulating pot, electric water boiling bucket, various electric water boilers such as electric water tank are used.As when being installed in the electric water hull that has circular electric heating tube metal pedestal, need not change former circular metal holder structure, can directly use.In 3 minutes, thermostat makes automatically and cuts off the electricity supply after the electric kettle boiling water seethes with excitement, and prevents to dryout boiling water in the kettle when unmanned guard from using and causes the electrical equipment accident.And when the boiling water temperature is reduced to 50 ℃ of left and right sides, this thermostat again automatically energized heat, play insulation effect.
The principle of work of this electric heating constant temperature controller is as follows: heat transfer element (opening aluminium circle) is given the temperature transfer in the electric water hull on the aluminium shell of electric heating constant temperature controller, give sphere form height sensitivity bimetallic strip 3 temperature transfer by shell again, utilize the rising-heat contracting-cold characteristic of bimetallic strip to do mechanical motion, promote ceramic fore-set 10, by this sudden change mechanical force, push the normally closed resilient contact in the electric heating constant temperature controller open, and cut off electrothermal tube power; When temperature reduced, bimetallic strip was got back to the original position state, and makes normally closed resilient contact get back to closure state, power connection, and electrothermal tube continues heating.
The utility model has the advantages that: security performance is good, and is practical.
