Abstract
The utility model discloses a temperature controller with the stable structure function, which comprises a bimetal piece, a bottom cover, a switch seat, a push rod, a movable contact, a movable contact piece, a fixed contact, a fixed contact piece, a connecting nut and a connecting terminal, wherein the movable contact is installed at one end of the movable contact piece; two ends of the push rod respectively lean against the bimetal piece and the movable contact piece; and the connecting terminal or the connecting nut is respectively connected with the movable contact and the fixed contact; the temperature controller is characterized in that one side of the bimetal piece is fixed on the switch seat, and the other side thereof is fixed in a blocking groove of the bottom cover. The bottom cover is provided with a blocking claw used for fixing the bimetal piece. In the temperature controller, one side of the bimetal piece is fixed on the switch seat, and the other side thereof is fixed in the blocking groove of the bottom cover, and the bottom cover is provided with the blocking claw used for fixing the bimetal piece. The bimetal piece plays the functions of blocking and fixing, so that the stability of the temperature of the temperature controller can be enhanced.
Description
Technical field
The utility model relates to a kind of thermostat, specifically a kind of thermostat with the stability structure function.
Background technology
On the product of the existing high temperature heater (HTH) that comprises electric heater, electric rice cooker etc. heating control apparatus is installed all, this heater is generally controlled by thermostat.Existing bimetallic temperature controller mainly is made up of bimetal leaf, bottom, switch base, push rod, contact, movable contact spring, binding post etc.The variation that bimetal leaf is experienced ambient temperature produces kick, drives push rod, and the pull switch break-make reaches the control purpose.Existing bi-metal temperature controller fixing unreliable because of to bimetal leaf, after action repeatedly, change in location has taken place in bimetal leaf, causes thermostat temperature drift or inefficacy.How to address this problem, become a difficult problem of pendulum in face of people.
Summary of the invention
The purpose of this utility model provides a kind of thermostat with the stability structure function.
The purpose of this utility model is achieved through the following technical solutions.
A kind of thermostat with the stability structure function, described thermostat comprises bimetal leaf, bottom, switch base, push rod, moving contact, movable contact spring, fixed contact, static contact, attaching nut and binding post, moving contact is installed in an end of movable contact spring, the two ends difference roof pressure of push rod is on bimetal leaf and movable contact spring, binding post or attaching nut are connected with moving contact, fixed contact respectively, it is characterized in that: the one side of described bimetal leaf is fixed on the switch base, and another side is fixed in the draw-in groove of bottom.
Establish the claw of firm bimetal leaf on the described bottom.
The utility model compared with prior art has the following advantages.
When the temperature that is heated device reached the temperature of controller setting, bimetal leaf kick automatically promoted push rod, cuts off switch, stops heating, makes device reach thermostatic control and overtemperature prote.The one side of the bimetal leaf in this thermostat is fixed on the switch base, and another side is fixed on the claw of establishing firm bimetal leaf in the draw-in groove of bottom on the bottom.Bimetal leaf is played screens and fixation, thereby strengthened the temperature stability of the type thermostat.
Description of drawings
Fig. 1 is the structural representation () of the thermostat of the utility model band stability structure function;
Fig. 2 is the structural representation (two) of the thermostat of the utility model band stability structure function;
Fig. 3 is the bottom cover structure figure () of the thermostat of the utility model band stability structure function;
Fig. 4 is the bottom cover structure figure (two) of the thermostat of the utility model band stability structure function.
Embodiment
Describe in further detail below in conjunction with the thermostat of accompanying drawing the utility model band stability structure function.
As shown in Figures 1 to 4, the thermostat of band stability structure function described in the utility model mainly is made up of bimetal leaf 3, bottom 2, switch base 1, push rod 4, movable contact spring 7, static contact 6, attaching nut 8 etc.When the temperature of utensil was elevated to the thermostat design temperature, bimetal leaf 3 produced kick, promotes push rod 4 then, and the sensitive switch of being made up of movable contact spring 7 and static contact 6 is cut off, and realized control action.The one side of bimetal leaf 3 is fixed on the switch base 1, and another side is fixed in the draw-in groove of bottom 2, and Stability Analysis of Structures is fixed.Establish the claw of firm bimetal leaf on the bottom of the type thermostat, improved the structural stability and the temperature stability of the type thermostat greatly.
Claims (2)
1. thermostat with the stability structure function, described thermostat comprises bimetal leaf, bottom, switch base, push rod, moving contact, movable contact spring, fixed contact, static contact, attaching nut and binding post, moving contact is installed in an end of movable contact spring, the two ends difference roof pressure of push rod is on bimetal leaf and movable contact spring, binding post or attaching nut are connected with moving contact, fixed contact respectively, it is characterized in that: the one side of described bimetal leaf is fixed on the switch base, and another side is fixed in the draw-in groove of bottom.
2. the thermostat of band stability structure function according to claim 1 is characterized in that: the claw of establishing firm bimetal leaf on the described bottom.
