Abstract

To solve the problem wherein there still remains uneven frost melting when a liquid refrigerant in an evaporator of a refrigerator incompletely evaporates and partly remains liquid to cause, upon energization of a defrosting heater, a high load at a portion with the remaining liquid refrigerant and a low load at a portion without a liquid refrigerant, although straight pipe parts of a refrigerant pipe of the evaporator are arranged horizontally relative to a refrigerator body and the refrigerator is installed horizontally by a height adjustment in the installation position so as to eliminate such unevenness. A refrigerator is constructed for design simplification by suppressed unevenness of frost melting in the same model. The refrigerator has an evaporator 8 installed at a slight tilt that is apparently conventional horizontal installation. The side where a liquid refrigerant stays can be identified as the right or left, and a structure design and a control design can be simply made accordingly.

Description

Refrigerator

Technical field

The present invention relates to a kind of refrigerator with defrosting Glass tube heater.

Background technology

To those of ordinary skill in the art, the structure that the evaporimeter (being also referred to as cooler) of relevant general refrigerator is peripheral all is quite clearly (reference example such as a patent documentation 1 to 6).

Refrigerator is the interior refrigerating chamber of instrumentation refrigerator and the temperature of refrigerating chamber, controls the ON/OFF of refrigerating circuit then, and the temperature of refrigerating chamber in the refrigerator and refrigerating chamber is adjusted to predetermined temperature.This refrigerator is the cold air that utilizes circulating cold air that the evaporimeter by refrigerating circuit is cooled, and circulates in refrigerator.

The refrigerant pipe of evaporimeter is to form the shape of crawling, and is to be made of a plurality of straight sections of linearity and the linking part (being also referred to as bent portion) that links these straight sections ends.And a plurality of fin are installed in the above-mentioned straight sections of evaporimeter.

And, the design of this evaporimeter is to make above-mentioned straight sections form level and be installed in the refrigerator, the air that refrigerating chamber in the refrigerator etc. returns is that the evaporimeter below flows into thus, and by between the fin, and the evaporimeter top flows out to refrigerating chamber in the refrigerator etc. once again thus again.

Therefore the air that flows into this evaporimeter has frost at evaporimeter and adheres to owing to being cooled to below the dew point through this evaporimeter.

In order to remove this frost, leave slightly evaporimeter below have the defrosting Glass tube heater to be arranged to approximate horizontal state (reference example such as above-mentioned patent documentation 1,2), or, be wholely set the defrosting Glass tube heater (for example with reference to above-mentioned patent documentation 3) of approximate horizontal state in the bottom of this evaporimeter.

Desirable situation is in the frosting equably of whole evaporimeter, then to make the white uniform dissolution of whole evaporimeter during defrosting in the cooling running.

But, in fact because near the air inflow, the situation that frosting takes place is more, and be the dissolving that around Glass tube heater, begins to carry out frost, so and can't all carry out equably.

Therefore, a kind of technology that makes even frosting is proposed.This technology is evaporimeter to be mounted to have certain gradient, makes the side inflow (with reference to above-mentioned patent documentation 4) of air from raising owing to this inclination simultaneously, can realize the homogenising of frosting by this.Yet, because evaporimeter is tilted, and make the horizontal inflow of air from evaporimeter, therefore beyond frosting aspect can produce difficulty.

At this, be illustrated at the control method that stops defrosting.The control that stops defrosting is to utilize to stop defrosting and detect with temperature sensor (stopping the temperature sense part of defrosting, hereinafter referred to as the defrosting temperature sensor) and detect and know.Therefore evaporimeter is equipped with detecting of stopping defrosting and uses temperature sensor.In addition, though the frosting distribution situation of evaporimeter is also inhomogeneous, and, utilize the dissolving of Glass tube heater to carry out also having under the situation uneven situation, but so long as its control that stops defrosting of the refrigerator of same configuration (same design) just have the similar of certain degree.

Normally at the position configuration defrosting temperature sensor that is speculated as white final residual (last frost dissolving).Then, when this defrosting temperature sensor senses when for example becoming 8 ℃, just stop the defrosting running.In addition, as mentioned above, the allocation position of defrosting temperature sensor is the optimum position with the position of white final residual, but because adhere to situation and the frost dissolving of frost are carried out situation and can be done to a certain degree supposition, therefore be not particularly limited the position of white final residual, even the periphery of the position of white final residual is also no problem.

Below, the Security Countermeasures during at the generation abnormal high temperature are illustrated.Utilize under the situation of glass tube Defrost heater defrosting, the temperature of this glass tube Defrost heater periphery can uprise.

Therefore, in when defrosting, the part of the refrigerator of Glass tube heater periphery be make its separately or the configuration al member be adversely affected because of high temperature avoiding.In addition, also Thermal Cutoffs can be configured near evaporator body or the evaporimeter, with forced termination defrosting action when forming the unusual condition of high temperature.This Thermal Cutoffs is to select in the middle of design temperature is 65 ℃, 68 ℃, 70 ℃, 75 ℃ Thermal Cutoffs, and is configured in the appropriate location of refrigerator.

The rising situation of the temperature of defrosting heater when situation, defrosting are carried out in the dissolving that this design is the distribution situation of analyzing the frosting of this refrigerator, utilize Glass tube heater and carrying out.And this situation is so long as the refrigerator of same configuration (same model), although some trickle deviation roughly is identical design.
