Specifically, when the refrigerator defrost, defrosting water is flowed into water-storing tray, when freezer compressor cumulative activation reaches default Time, defrost reaches the default defrost time or default defrost stops temperature, the water surface when refrigerator stops defrost, in water-storing tray Height is higher than the water outlet of the drainpipe.

The open-close detection apparatus includes the magnet being arranged in one of refrigerator body or refrigerator door, and setting Magnet-sensitive switch on wherein another, when refrigerator doors are separated with storage compartment, change in location between magnet and magnet-sensitive switch is drawn The changes of magnetic field that magnet-sensitive switch detects is played, to detect that refrigerator doors are opened, alternatively, it is also possible to use traditional mechanical rotation The sensor of refrigerator doors opening and closing can be detected by turning on pass or other;

The pressure test device is for detecting refrigerator inside air pressure, when refrigerator doors are opened, indoor air pressure between storage It is equal with atmospheric pressure, when refrigerator doors are closed, since internal temperature of refrigerator is low, it will form negative pressure, pressure test device detects Refrigerator inside air pressure reduces, and temperature-detecting device measures internal temperature of refrigerator reduction;

When the constant temperature in refrigerator reduces, if the good airproof performance of refrigerator, under the premise of gastight, the volume of refrigerator Centainly, the pressure in refrigerator can also continue to reduce.

The detection method of the refrigerator leakproofness of the present embodiment, includes the following steps:

Water surface elevation in water-storing tray is higher than the water outlet of the drainpipe;

Refrigerator doors are closed;

Record indoor temperature and atmospheric pressure value between the storage;

According to the variation relation of temperature and atmospheric pressure value, refrigerator leakproofness is determined.

Further, the temperature-detecting device detects indoor initial temperature between the storage, the air pressure detection dress Set indoor initial gas pressure between detecting the storage;

The pressure test device detects indoor real-time air pressure between the storage;

The processor compares under the conditions of certain temperature, when the difference of initial gas pressure and initial gas pressure is less than or equal to preset Lowest difference value determines refrigerator gas leakage.

Specifically, initial temperature T1 and initial gas pressure P1 is recorded, when open-close detection apparatus detects that refrigerator doors are closed, after It is continuous to detect the real-time air pressure P2 in refrigerator in next step, the value of P2-P1 is denoted as Δ P1 under conditions of initial temperature is T1 and is preset Lowest difference value is denoted as Δ Pmin, as Δ P1≤Δ Pmin, continues to judge in next step, otherwise, terminates gas leakage and determine.

Due to the judgement of refrigerator leakproofness, there are certain conditions, inevitably there is the small gas leakage of some degree The small air leakage is not precluded in amount, the present embodiment, that is to say, that when Δ P1 > Δ Pmin, it is not intended to which refrigerator does not leak completely Gas, but the satisfactory value of the amount of the gas leakage, the sealing performance of refrigerator meet the requirements.

In addition, when the variation relation of temperature and atmospheric pressure value satisfaction judges refrigerator poor sealing, detection refrigeration for refrigerator is No end, if it is not, the real-time air pressure in detection refrigerator is repeated, if so, obtaining the conclusion of refrigerator gas leakage;

Since at the end of refrigerator does not freeze, the air pressure at a certain moment may fail to change in time, at the end of refrigeration, this When can determine gas leakage as a result, therefore, when increasing whether refrigeration terminates this Rule of judgment, be conducive to allow the judging result more Accurately.

Further, the water surface elevation in water-storing tray is higher than the water outlet of the drainpipe, comprising:

Freezer compressor cumulative activation reaches preset time;

The refrigerator defrost;

Defrost reaches the default defrost time or default defrost stops temperature, stops defrost.

Further, it further comprises the steps of:

When detecting that refrigerator doors are opened, stop detection refrigerator leakproofness.

Compressor cumulative activation is set to reach preset time, so that the refrigeration in refrigerator reaches a certain level, defrost energy at this time The water of outflow is enough, and the water surface elevation in water-storing tray did not had the water outlet of drainpipe enough, to ensure in discharge outlet by watertight It is detected under conditions of envelope;

Additionally, due to the detection of the leakproofness, dependent on the relationship of detection temperature and air pressure, when refrigerator doors are opened, storage Between the air pressure of chamber interior be equal to atmospheric pressure, internal temperature is equal to room temperature, and usually will form after refrigeration for refrigerator, in refrigerator negative Pressure, after opening refrigerator doors at this time, air pressure inside can be equal with external atmosphere pressure, also will form air pressure raising and temperature is raised existing As, it is therefore desirable under the premise of refrigerator doors are closed always, the leakproofness of refrigerator is judged by detection atmospheric pressure value and temperature value, when When refrigerator doors are opened, stops detection and avoid because the change of environment influences judging result.

Compared with prior art, the present embodiment has the advantages that

(1) in preparatory closing refrigerator door, and under conditions of determining that the water outlet of drainpipe is sealed, pass through detection refrigerator Interior air pressure and temperature reach relationship, judge the leakproofness of refrigerator, if the relationship between air pressure and temperature and preset value are not inconsistent, sentence Disconnected poor sealing out.

(2) it by being detected to the case where air pressure change under identical initial temperature, by the changing value of air pressure and presets most Low difference compares, and judges the sealing situation of refrigerator, and terminate in refrigeration for refrigerator, and refrigerator doors are shut, the water outlet of drainpipe Mouth is judged that deterministic process is simple, as a result reliably below the water surface of water-storing tray.

Embodiment 2

Join Fig. 2 provided by another embodiment, the present embodiment the difference from embodiment 1 is that: to drainpipe ice block up sentence Disconnected program is different.

Specifically, temperature T2, T3 of the temperature-detecting device detection different moments, the pressure test device detection pair Atmospheric pressure value P2, the P3 for the different moments answered, the processor calculate the temperature gap T3-T2=of different moments temperature change The Δ T2 and air pressure difference P3-P2=Δ P2 of the atmospheric pressure value of corresponding different moments variation;

The processor relatively corresponds to the temperature gap at moment and the relationship delta Δ T2/ Δ P2=of the air pressure difference K determines refrigerator gas leakage when the ratio k of the temperature gap and air pressure difference is more than or equal to default ratio.

Due to refrigerator in use, internal storage article is different, the temperature difference that volume is different, needs to freeze, refrigerator are occupied The environment of work usually changes, and the absolute value of air pressure change is usually little, in order to avoid volume change generates air pressure change Influence and air pressure change the little problem of absolute value, the present embodiment is by the relationship between air pressure change and temperature change Illustrate when the case where variation between air pressure and temperature being more than or equal to default maximum changing value same as judgment criteria Under the conditions of temperature change, the variation of air pressure is smaller, and denominator is caused to reduce, so that k becomes larger, illustrates that there are problems for sealing;Principle class The relationship of the case where being similar to detected slope variation or velocity variations and acceleration change excludes refrigerator work according to the variation of slope When making environmental change, the interference of inaccuracy is detected caused by the variation of air pressure numerical value is smaller.

Further, referring to embodiment 1, when the variation relation of temperature and atmospheric pressure value satisfaction judges refrigerator poor sealing When, whether detection refrigeration for refrigerator terminates, if it is not, the air pressure and temperature in detection refrigerator are repeated, if so, obtaining the knot of refrigerator gas leakage By;

Since at the end of refrigerator does not freeze, the air pressure at a certain moment may fail to change in time, at the end of refrigeration, this When can determine gas leakage as a result, therefore, when increasing whether refrigeration terminates this Rule of judgment, be conducive to allow the judging result more Accurately.

Compared with prior art, the present embodiment has the advantages that by changing between detection air pressure and temperature Relationship, when the acquirement of the difference of temperature is smaller, as a result more accurate, the interference and air pressure that avoid environmental change from generating and temperature The absolute value of difference is small to be difficult to the problem of differentiating, thus obtain refrigerator whether the conclusion of gas leakage.

Embodiment 3

Join Fig. 3 provided by another embodiment, the present embodiment the difference from embodiment 1 is that: to drainpipe ice block up sentence Disconnected program is different.

Specifically, indoor real time temperature T4 and corresponding real-time atmospheric pressure value P4 between the storage is detected;

When real time temperature reaches minimum, the corresponding real-time atmospheric pressure value P4 of real time temperature is more than or equal to default maximum gas pressure Value Pmax determines refrigerator gas leakage.

Whether detection temperature reaches minimum, can be compared by the temperature of time adjacent segments, when the temperature of subsequent time Equal to the temperature of last moment, and at the end of refrigeration, judge that the moment temperature is minimum.

Default maximum gas pressure value Pmax, according to the minimum requirements to refrigerator-door seal, minimum requirements is lower to reach for detection To maximum gas pressure value be denoted as Pmax.

Further, referring to embodiment 1, when the variation relation of temperature and atmospheric pressure value satisfaction judges refrigerator poor sealing When, whether detection refrigeration for refrigerator terminates, if it is not, the air pressure and temperature in detection refrigerator are repeated, if so, obtaining the knot of refrigerator gas leakage By;

Since at the end of refrigerator does not freeze, the air pressure at a certain moment may fail to change in time, at the end of refrigeration, this When can determine gas leakage as a result, therefore, when increasing whether refrigeration terminates this Rule of judgment, be conducive to allow the judging result more Accurately.

The judgment method logic is simple, i.e., when refrigerator temperature reaches it is minimum when, it should at the time of being that pressure is minimum in refrigerator, It is minimum to can determine whether out that the leakproofness of the refrigerator has not yet been reached if it is greater than or equal to default maximum gas pressure value Pmax by atmospheric pressure value P4 at this time It is required that refrigerator leakage problem is serious, issues gas leakage and remind.

Compared with prior art, the present embodiment has the advantages that by simple decision logic, to the close of refrigerator Envelope property is effectively detected and is judged, the effect of protection is played.

Illustrating only for feasible embodiment of the invention is described in detail in those listed above, they are simultaneously It is non-to limit the scope of the invention, it is all without departing from equivalent implementations made by technical spirit of the present invention or change should all It is included within protection scope of the present invention.
