Technical field
The utility model relates to a kind of thermostat, relates to a kind of bloated two adjustable type thermostats of the temperature controlled liquid of electrical equipment that are used for particularly.
Background technology
Temperature controller; be called for short thermostat; also claim temperature detect switch (TDS); its role is to; generally be serially connected on the power circuit of electrical equipment; to with temperature correlation or responsive heat, the temperature of refrigeration appliance product, play control circuit break-make and protective effect, be widely used in the temperature protection and the control aspect of electrical equipment such as electric rice cooker, electric water bottle, electromagnetic oven, coffee pot, baking oven, warmer, deep fryer now.So safe and reliable property, temperature regulating range and the thermoregulator accuracy thereof of temperature controller all can produce significant effects to the service behaviour of electrical equipment.
Liquid expanding temperature detect switch (TDS) is a kind of pressure type temp control switch, also is a kind of mechanical control device, its principle is to utilize variation of temperature, the volume of enclosed liquid is changed, and the rock deformation pressure of generation is controlled being switched on or switched off of contact, thereby reaches the effect of control circuit.
Because constantly weeding out the old and bring forth the new of various novel electrical equipment also makes more and more higher to the performance requirement of thermostat.The quality of the service behaviour of liquid expanding thermostat is very big to the service behaviour influence of electrical equipment.Thermostat mainly contains bimetal strip thermostat, liquid expanding thermostat etc. at present, and main principle all is to utilize the principle of expanding with heat and contract with cold, and drives the action of active and static contact assembly, cuts off or the conducting current path.As Chinese patent 03221172.4 disclosed a kind of temperature controller.Different is, bimetal strip thermostat is to adopt the action of bimetal leaf to drive the action of active and static contact assembly, and liquid expanding thermostat then is by the breathing of the liquid in the liquid storage tube, through brake assemblies, drives the action of active and static contact assembly.
Different electrical equipment also has difference to the needs of thermostat performance index, and on the whole, requirement is more and more higher, especially for the requirement of the accuracy of default brake temperature, accuracy aspect that brake temperature is regulated.But existing liquid expanding thermostat all is to adopt dull joint mode, and adjusting knob promptly only is provided, and drives the regulating shaft rotation, changes the axial location of regulating shaft, thereby regulates the regulative mode of default brake temperature.The shortcoming of this thermostat is, regulates default brake temperature and carry out the precision of follow-up brake temperature when regulating lower, and the start-stop temperature difference is bigger, and temperature control is not accurate enough, and adjustable range is not wide, can not satisfy the demand of various novel electrical equipment.
The utility model content
The purpose of this utility model is, above-mentioned defective at existing liquid expanding thermostat technology existence, a kind of two kinds of temperature-adjusting devices that are provided with are provided, can make thermostat realize and the precision when carrying out subsequent adjustment obtains bigger raising to the default of its brake temperature, the start-stop temperature difference of thermostat is reduced, the temperature precise control, the bloated pair adjustable type thermostats of the liquid of adjustable range broadening.
The technical scheme that the utility model provides is as follows: the bloated pair adjustable type thermostats of a kind of liquid, comprise loam cake, shell holder, ground plate, liquid storage tube, catheter, hydraulic brake assembly, the active and static contact assembly, electrode nipple, insulation board, the regulating shaft assembly, hydraulic brake assembly, the active and static contact assembly, electrode nipple, insulation board is separately fixed on the shell holder, it is characterized in that: the stage casing of regulating shaft is provided with external screw thread, described thermostat at least also includes one and is enclosed within on the described regulating shaft, be meshed with described regulating shaft external screw thread, be used for regulating shaft is connected on the shell holder, and the swivel nut of scalable regulating shaft axial location.
Described swivel nut is that a stage casing is provided with the shirt rim to outer lug, dorsad on the side end face of shell holder, is provided with two or four breach at described swivel nut symmetrically.
The external screw thread in described regulating shaft stage casing, and the internal thread of the swivel nut that is meshed with it can be left hand thread, or right-handed thread.
Described active and static contact assembly comprises static contact and movable contact spring, and its construction of switch is a kind of in single-pole single-throw(SPST or the single-pole double throw.Described active and static contact assembly, its brake switch structure be normally closed or often open in a kind of; During the hilted broadsword double end, can do direct action or reverse action and carry out temperature control.
Described hydraulic brake assembly comprises braking metal dish, fixed arm, braking contact, and metal dish and contact are fixed on the fixed arm; One end of fixed arm is fixed on the shell holder, and the other end is unsettled and be fixed with the braking contact; Metal dish is arranged on the middle part of fixed arm, and is connected as a single entity with described fixed arm.
The utility model, when using regulating shaft to regulate temperature, the angle of directly rotating regulating shaft gets final product; The anglec of rotation of regulating shaft is between the 0-330 degree.When using swivel nut to regulate temperature, can be as required, the angle of using private key to rotate swivel nut; The angle of swivel nut rotation is between the 0-720 degree or more.The key of this special use, suitable with notch geometry and quantity on the swivel nut, can be two teeth or four teeth.
Advantage of the present utility model is: because the utility model is provided with two kinds of temperature-adjusting devices, can adopt two kinds of methods to regulate, thereby make thermostat to the default of its brake temperature and when carrying out subsequent adjustment, can carry out meticulous trace regulates, make the precision of adjusting obtain bigger raising, the start-stop temperature difference of thermostat is reduced, temperature precise control, adjustable range broadening.The utlity model has than the bloated more superior performance of adjustable thermostat of single adjustable type liquid, the temperature adjusting range increases, can make it be in different angles by rotation regulating shaft and swivel nut, accurately adjust its axial location, just can obtain accurate break-make control temperature.
The utility model also has advantage simple to operate, easy to use, can be widely used in the manufacturing of various liquid expanding thermostats.The utility model break-make has a narrow range of temperature, and adjusts the precision height, switch motion sensitivity, long service life.Can be widely used in various electric heating or refrigerating appliances such as water boiler, shower, electric heating tableware, roaster, deep fryer, freezing-cooling storeroom, electric heater, water dispenser, incubator, food machinery, package packing machine, medicine equipment, or other electrical equipment.
