Description
Technical field
The utility model relates to a kind of anhydrous and overtemperature protection water-heater control device of being used for, and relates in particular to a kind of radio hot-water bottle overheat protector assembly.
Background technology
The overtemperature protection control device that existing radio hot-water bottle and liquid heater are used; claim control device preventing dry fry again; it mainly is used to be installed in the bottom of radio hot-water bottle and liquid heating vessel; radio hot-water bottle and liquid heating vessel bottom then are equipped with electrical heating elements; in above-mentioned radio hot-water bottle and liquid heating vessel; in order to prevent anhydrous and the dry combustion method phenomenon; generally all in radio hot-water bottle and liquid heating vessel bottom; one overheat protector assembly is installed, the contact point of when anhydrous and dry combustion method, cutting off the electricity supply.
As the patent No. is a kind of overheat protector assembly the Chinese invention patent application " liquid heating ware overheating protection controller assembly " of ZL200810120107.4 (notification number is CN101629758A) has disclosed, and includes a control body; Control body upper surface is provided with the conjuncted two braking heat-sensitive duplex metal brakes of monolithic, the conjuncted two braking heat-sensitive duplex metal brakes of described monolithic are the brake units that form two relatively independent doublets on a slice bimetallic sheet material, it is the inboard that the equal part of edge line of each brake unit in described two brake units falls into another brake unit edge line, the conjuncted two braking heat-sensitive duplex metal brakes of described monolithic have a public connection part, this public point of attachment also makes two brake units constitute the conjuncted two braking heat-sensitive duplex metal brakes of monolithic in the inboard of edge line of each brake unit effectively, correspondingly control and also be provided with two groups of make and break contacts on the body, every group of make and break contact matches with a corresponding brake unit.Two brake units of the conjuncted two braking heat-sensitive duplex metal brakes of monolithic are easier under the prerequisite of two brake unit brakings produces braking at same temperature spot.
The heat-sensitive duplex metal of this patent application is conjuncted pair of brake body of monolithic; in radio hot-water bottle and the actual use of liquid heating vessel; the overfire protection controller of conjuncted pair of brake body of this monolithic; in fact only provide one-level other anhydrous and dry burning protection function; because this structure is easy to produce action under a temperature spot, and the bimetal leaf of this structure, all is to be fixed on the fixed head inflexibly; some free gaps all do not have, and are easy to produce temperature deviation like this.In addition, because two bimetal leafs are structure as a whole, both recurvation power can produce and influence each other, and has reduced the sensitivity and the precision of temperature-sensitive action, makes product quality stability have problems.
What and for example another patent No. was that the Chinese invention patent " the whole radio air connector and the thermally-responsive controls assembly that are used for water-boiling vessel " of ZL95194418.5 (notification number CN1065406C) discloses is so a kind of overheat protector assembly; one controller that combines with liquid heating vessel skin bottom; comprise a carrier; in its opposite end portion two bimetallic brakes are installed; be installed in the position that separates of laterally leaving the connector central axial line on the controller face; described brake is installed or with water container bottom or electrical heating elements good thermo-contact is arranged; thereby the temperature when using can be separated each brake of position and be sensed on the bottom of water container or the electrical heating elements; interrelate with each brake and with coupled device and its coupled operationally electric switch contact; described electric switch contact and the coupled device that interrelates thereof are installed in a side of dedicated radio link device, and its installation will make two brakes when because of the anhydrous heating of water container or dryout water and produced heat energy and operate independently of each other to open the contact that links mutually and cut off the electricity supply.
