Abstract
The invention relates to a method for using a magnetic-sensing temperature switch in a refrigerator, which mainly solves the problem of temperature compensation under the condition that when environmental temperature is close to the temperature of a refrigerating room, a compressor stops working but the refrigerating room still needs refrigeration. Conventional temperature compensation is realizedby the method that an illuminating lamp is manually turned on to heat up the refrigerating room, or the environmental temperature is induced by the magnetic-sensing temperature switch to automatically turn the illuminating lamp on for heating up the refrigerating room so as to trigger a sensing probe, and then the compressor is turned on. The conventional technology compensates temperature through the illuminating lamp, though the temperature of a refrigerator can be effectively controlled, automatic control sensitivity and refrigeration efficiency are low. In the invention, a resistance wirewith a resistance value larger than the resistance value of the lamp is connected with the magnetic-sensing temperature switch in series so as to form a temperature control circuit, and then the temperature control circuit is connected with an illuminating lamp working circuit and a compressor working circuit in parallel, wherein the resistance wire is arranged on the sensing probe of the refrigerating room. When the change of the environmental temperature ensures that the magnetic-sensing temperature switch is turned off, because the resistance wire directly heats the probe, the compressor can quickly start up to work, and the refrigeration efficiency and the temperature automatic control sensitivity are improved.
Description
Technical field
The present invention relates to a kind of using method of circuit controling switch, exactly disclose the using method of a kind of magnetic-sensing temperature switch on refrigerator.
Background technology
When at present the refrigerator that uses was in environment temperature 〉=9 ℃, temperature and the environment temperature of refrigerating chamber were approaching, and refrigeration stops automatically in the refrigerating chamber, but owing to there is not the low temperature parameter to control in the refrigerating chamber, the refrigeration of refrigerating chamber also can stop immediately.Be easy to like this cause damage, even allow the user take for to be the damage of refrigerator parts, in vain increase unnecessary worry to the food of depositing.Therefore in environment temperature during near 9 ℃, need manually to adjust the circuit control of refrigerating chamber, start lighting bulb, refrigerating chamber is carried out temperature-compensating, make and place probe induction refrigerating chamber and that connect with the refrigeration control circuit of control refrigerating chamber, thereby make compressor be in starting state, reach the purpose that refrigerating chamber continues refrigeration.This manual control temperature-compensating lacks the people of refrigerator operation general knowledge for some, is difficult in time determine the time and the season of manual adjustments, because people to the slight change of temperature, feel it is not clearly.At the problem that exists.Application number is: 01210354.3 technological invention discloses a kind of use magnetosensitive temperature sensitive switch and refrigerator is carried out temperature has controlled compensation technique automatically.This kind technology not only can replace traditional manual adjustments, and makes refrigerator realize automation control basically.Because this technology is by a temperature sensitive switch and refrigerator lighting bulb switch in parallel, and then connects with lighting bulb, temperature is compensated so its effect is equivalent to open refrigerator door or starts lighting bulb.But this technology also has its weak point; be exactly when critical 9 ℃ of environment temperature; perhaps environment temperature continues to raise; the magnetic-sensing temperature switch closure; start lighting bulb and heat, because it is bulb power is limited, longer to the indoor heating and continuous time; in period, compressor is in stopped status at this section.Therefore this technology has influenced the susceptibility of freezer temperature control comparatively speaking, has reduced the service life of bulb.
Summary of the invention
For the variation of solution refrigerator because of environment temperature influences refrigerating efficiency, improves the sensitivity of freezer temperature control and the problems such as service life that prolong lighting bulb, the invention discloses the using method of a kind of magnetic-sensing temperature switch on refrigerator.It mainly comprises: magnetic-sensing temperature switch, connector, resistance wire, temperature control circuit.It is characterized in that: magnetic-sensing temperature switch comprises tongue tube, two permanent-magnetic clamps, a soft magnetism ring, pin, connector, the soft magnetism ring set is put in the periphery of tongue tube adapter ring around tongue tube reed opening and closing, two permanent-magnetic clamps closely adhere on the both sides of soft magnetism ring, and by gluing fixing, the bending pins of tongue tube one end is in tongue tube one side, be plugged in connector side by side with the pin of the other end, an end that is installed with the tongue tube bending pin of permanent-magnetic clamp and soft magnetism ring is inserted a cross section be water droplet shape, one end opens wide in the tubular shell of end sealing, infusion epoxy resin in the water droplet shape body, an end of the remainder of the outer two pins of water droplet shape tubular shell and connector are pegged graft fixing; Magnetic-sensing temperature switch forms temperature control circuit by connector and resistance wire series connection, and form in parallelly with the operating circuit of freezer compressor and the lighting bulb operating circuit in the refrigerator, resistance wire is looped around and places the inductive probe position of connecting with compressor in the refrigerating chamber on the refrigerating chamber outer wall.When environment temperature 〉=9 ℃, magnetic-sensing temperature switch closed work influenced by ambient temperature, the starting resistance silk heats the inductive probe in the refrigerating chamber, because of the power big (lighting bulb power with refrigerator setting be reference) of resistance wire power than lighting bulb, and directly act on probe, inductive probe promptly starts refrigeration circuit rapidly.When environment temperature＜9 ℃ during near the temperature of refrigerating chamber (critical-temperature that each manufacturer is provided with has nuance), magnetic-sensing temperature switch is in off-state, and resistance wire quits work; The temperature of refrigerating chamber, refrigerating chamber is not subjected to the influence of environment temperature, is in normal operating conditions.When environment temperature≤15 ℃, the soft magnetism ring is subjected to the influence of environment temperature, logical magnetic characteristic takes place sharply to change, and the reed in the tongue tube is disconnected, resistance wire quits work, to such an extent as to environment temperature magnetic-sensing temperature switch more than 15 ℃ the time all is in off-state, this is the characteristic decision of soft magnetism ring itself.The interior temperature of refrigerating chamber this moment is subjected to the influence of environment temperature bigger, makes compressor be in normal duty by inductive probe.Therefore, the using method of magnetic-sensing temperature switch disclosed in this invention has not only realized the Automatic Control of refrigerator under any environment temperature, and has improved refrigerating efficiency, strengthened the sensitivity of automatic control.
