Abstract
The utility model provides a pressurized type temperature controller, which comprises an LWD series pressurized type temperature controller. The utility model is characterized in that a fixed seat provided with heat conduction grooves is arranged between a machine frame and a corrugated pipe. The inner parts of the heat conduction grooves on both sides of the fixed seat are provided with two heaters which are connected in series. Two end heads of the heater are respectively connected with a C terminal and an L terminal. The thermostat formed in the way can realize that the temperature controller can realize that purpose that the temperature of the corrugated pipe is higher than the temperature of a temperature sensing part under the condition of lower environmental temperature. The utility model is characterized in simple and compact structure, small size, easy implementation, etc.
Description
The utility model relates to temperature control equipment, particularly a kind of compression-type temperature controller.
At present, be used for refrigerator, refrigerator as the LWD series electric temperature regulator type compression-type temperature controller that temperature is controlled and automatic defrosting is used, when environment temperature was lower than-5～8 ℃, the temperature that is loaded on temperature controller housing inner corrugated pipe had also dropped to lower temperature thereupon.When compressor cooling reached specified temp, the switch in the switch enclosure between C, the L terminal disconnected, and compressor quits work, and refrigerator enters the automatic defrosting state.Owing to be contained in the defrost heat effect on the evaporator, evaporator temperature risen.Because the residing position of corrugated tube is away from defrosting heater, so the temperature rising is slower, at this moment, the temperature of corrugated tube part then can be lower than the temperature of evaporator temperature-sensitive portion.Thereby the temperature that can not satisfy saturated vapour pressure formula temperature controller corrugated tube part must be higher than the requirement that temperature-sensitive portion temperature could satisfy.Thereby cause temperature controller not start shooting by former turn-on temperature, then temperature controller is with regard to the effect of temperature out of hand.
The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of can guarantee that the temperature of corrugated tube is higher than the compression-type temperature controller of the temperature-sensitive portion temperature of evaporator all the time.
The purpose of this utility model is achieved by the following scheme: this temperature controller comprises LWD series compression-type temperature controller, by frame, corrugated tube, switch enclosure, temperature-sensitive pipe, C, L end, formation such as dividing plate and compressor, wherein between frame and corrugated tube, be provided with the semicircle shape holder of band thermal trough, the thermal trough that is positioned at these holder both sides is provided with two heaters that are cascaded, the two ends of two heaters respectively with switch enclosure in C terminal and L terminal constitute and to be connected.
Compared with the prior art, the utlity model has following advantage:
1, heater is contained in the interior cavity between corrugated tube and frame of LWD series compression-type temperature controller housing, compact conformation, and it is convenient to implement.
2, heater is distributed on the corrugated tube both sides, and the semicircular in shape state of siege, can realize the best thermal effect that adds, and power consumption is very little.
3, security performance is good, meets the household electrical appliance safety standard of control automatically fully.
Below in conjunction with accompanying drawing the utility model is illustrated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the combination barrier synoptic diagram;
Fig. 3 is that the A-A of Fig. 2 is to cut-away view;
Fig. 4 is a semicircle shape holder synoptic diagram;
Fig. 5 is an electrical schematic diagram of the present utility model.
As Fig. 1-shown in Figure 5: this temperature controller is made of frame 1, corrugated tube 2, heater 3, insulating sleeve 4, semicircle shape holder 5, switch enclosure 6, temperature-sensitive pipe 7, C terminal 8, L terminal 9, dividing plate 10, compressor 11.
Embodiment: the utility model is to draw on the basis of device in LWD series electric temperature regulator R type pressure type temperature, sets up heating function in former temperature controller.Concrete scheme is the semicircle shape holder 5 that a band thermal trough is set in the cavity between frame 1 and corrugated tube 2, and the while is provided with two heaters that are cascaded 3 in the thermal trough of holder.This heater can be a resistor, also can be PCT semiconductor heater element.Adopt its two resistance, one end of resistor heats body (as shown in Figure 5) to be cascaded, suit insulating sleeve 4 is insulated simultaneously, in addition two ends respectively with switch enclosure 6 in C terminal 8 and L terminal 9 constitute and be connected.
Its principle of work is: as shown in Figure 5, when temperature is higher in the refrigerator, the C terminal 8 of switch enclosure 6, the switch connection between the L terminal 9, compressor 11 refrigeration of starting working, the switch institute short circuit that this moment, calandria 3 was switched on, calandria is not worked.When refrigerator temperature drops to the control temperature, switch between C terminal and the L terminal disconnects, supply voltage is added to the calandria two ends by compressor 11 windings, calandria begins heating, heating is near its corrugated tube 2 simultaneously, the corrugated tube temperature rises, thereby the temperature that has satisfied saturated vapour pressure formula temperature controller corrugated tube must be higher than the requirement of temperature-sensitive portion temperature, has guaranteed that LWD series compression-type temperature controller all can reach the purpose of operate as normal at (more than 5 ℃) under the lower environment temperature.
