The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The refrigerator in the market at present has fewer unfreezing chambers and poor unfreezing effect, and the main reason is that more attention is paid to the refrigeration speed and the refrigeration effect, so that the unfreezing effect which is a function closely related to a user is ignored.

In one embodiment, as shown in fig. 1, there is provided a thawing method comprising the steps of:

and step 110, controlling the heating assembly to heat the thermostatic chamber.

Step 130, detecting whether the temperature of the thermostatic chamber is greater than or equal to a first preset temperature.

And 150, when the temperature of the thermostatic chamber is greater than or equal to a first preset temperature, controlling the heating assembly to stop working, controlling the air guide assembly to convey the air in the refrigerating chamber into the thermostatic chamber through the first channel, controlling the adjusting assembly to convey mixed air into the unfreezing chamber through the second channel, wherein the mixed air is formed by mixing the air conveyed into the thermostatic chamber through the first channel and the air in the thermostatic chamber.

And step 160, when the temperature of the thermostatic chamber is lower than the first preset temperature, returning to the step of controlling the heating assembly to heat the thermostatic chamber.

In the thawing method, the heating assembly is controlled to heat the thermostatic chamber, so that the temperature of the gas in the thermostatic chamber is increased, the temperature of the gas in the thermostatic chamber is higher than that of the gas in the refrigerating chamber, and whether the temperature of the thermostatic chamber is higher than or equal to a first preset temperature is detected. The first preset temperature is a temperature threshold value for starting the air guide assembly. When the temperature of thermostatic chamber is greater than or equal to first preset temperature, control heating element stop work, carry the indoor gas of cold-stored room to the thermostatic chamber through first passageway through control wind guide assembly, so that the indoor gas of cold-stored room and the indoor gas mixture of thermostatic chamber form mist, therefore, the indoor gas of cold-stored room has reduced the indoor gas temperature of thermostatic chamber, form mist, mist's temperature is comparatively gentle, blow mist to the thawing chamber through control adjusting part, can make mist unfreeze the indoor article of thawing uniformly. The adjusting component is used for adjusting the second channel, namely opening or closing the second channel so as to control whether the mixed gas is blown to the thawing chamber or not. When the indoor article that unfreezes is food, then can unfreeze indoor food to unfreezing uniformly, when the indoor article that unfreezes is the meat, then can unfreeze indoor meat to unfreezing uniformly, reach the purpose that the forced air cooling constant temperature unfreezes, make meat process of unfreezing speed faster, and the condition that the blood seepage can not appear in the meat through evenly unfreezing, can not cause the pollution to the refrigerator. And because the heating assembly can continuously heat, the heat of the compressor is not required to be relied on, so that the object in the thawing chamber can be well thawed at any time. And when the temperature of the thermostatic chamber is lower than the first preset temperature, the step of controlling the heating assembly to heat the thermostatic chamber is executed again, so that the air supply and the unfreezing of the articles in the unfreezing chamber can be ensured in time.

It can be understood, cold-stored room is used for freezing article, consequently, the indoor gas temperature of cold-stored room is lower, and the thermostatic chamber heats through heating element, in order to promote gaseous programming rate, heating element's temperature is higher, can reach 30 ~ 40 ℃ generally, make the indoor gas temperature of thermostatic chamber higher, and because heat the inside gas of thermostatic chamber through heating element, the inhomogeneous condition of being heated appears easily in the inside gas of thermostatic chamber, should not directly send the indoor gas of thermostatic chamber to the freezer directly, in the above-mentioned embodiment, mix through the indoor gas of gaseous and the indoor gas of thermostatic chamber of cold-stored room, make the temperature of mist even, and mist's temperature can not be too high, like this, carry mist to the thawing room can be well to the even thawing treatment of meat.

In this embodiment, since the temperature of the thawing chamber does not reach the second preset temperature, the temperature of the thawing chamber needs to be raised continuously, and the step of detecting whether the temperature of the thermostatic chamber is greater than or equal to the first preset temperature is executed again, so as to check whether the gas in the thermostatic chamber meets the requirement of being conveyed to the thawing chamber. If the temperature of the gas in the thermostatic chamber reaches the standard, mixed gas is formed in the thermostatic chamber and the temperature of the thawing chamber is continuously reduced. And if the temperature of the gas in the thermostatic chamber does not reach the standard, continuing to heat the thermostatic chamber.

As shown in fig. 3 and 4, in order to explain the present application more clearly, in one embodiment, a refrigerator having a constant temperature thawing function, that is, the refrigerator of the above embodiment, is provided. The refrigerator with constant temperature thawing function of this application includes as follows: the thermostatic chamber 220 is arranged in the freezing chamber, the thermostatic chamber 220 is provided with an air inlet and an air outlet, the refrigerating evaporator 211 is connected with the thermostatic chamber 220 through the first channel 310, and it can be understood that the refrigerating evaporator 211 is used for cooling the refrigerating chamber 210, therefore, the refrigerating evaporator 211 is connected with the thermostatic chamber 220 through the cooling chamber and the first channel 310, and the fan 311 is arranged in the first channel 310. The air outlet of the refrigerating compartment 210 is communicated with the air inlet of the thermostatic chamber 220 through a first channel 310, the thermostatic chamber 220 is connected with the unfreezing chamber 230 through a second channel 320, and an air door 321 is arranged in the second channel 320, so that when the unfreezing is not performed, the air door 321 and the fan 311 are both closed. The thermostatic chamber 220 is provided with a temperature sensor and a steel pipe heating assembly 221, the heating assembly 221 and the temperature sensor are connected through a main control board, and the temperature sensor can control the heating assembly 221 to be turned on and off. The thawing chamber 230 is provided with an air inlet, the air outlet of the thermostatic chamber 220 is communicated with the air inlet of the thawing chamber 230 through a second channel 320, the air inlet of the thawing chamber 230 is controlled to be communicated and cut off by an air door 321 of the second channel 320, the thawing chamber 230 is also provided with an air return inlet, and the air return inlet of the thawing chamber 230 is communicated with the air inlet of the cold storage room 210 through a second air channel. A plurality of wire racks 231 are provided in the thawing chamber 230.

As shown in fig. 3, the constant temperature thawing system of the present invention is generally divided into three compartments in a freezing compartment, namely, a refrigerating compartment 210, a constant temperature compartment 220, and a thawing compartment 230. The refrigerating compartment 210 and the thermostatic compartment 220 are connected by a first channel 310, and a fan 311 is disposed in the first channel 310. The thermostatic chamber 220 and the thawing chamber 230 are connected through a second passage 320, and a damper 321 is provided in the second passage 320. The thermostatic chamber 220 is provided with a first temperature sensor; the thawing chamber 230 is provided with a second temperature sensor. The thermostatic chamber 220 is provided with a heating assembly 221. Wherein the arrows in fig. 3 indicate the flow direction of the gas in the system.

In a state where the defrosting method is not performed in the refrigerator, the damper 321 and the fan 311 are both in a closed state, the freezing chamber is normally cooled by the refrigerating evaporator 211, the refrigerating evaporator 211 mainly supplies cold air to the refrigerating compartment 210, the thermostatic chamber 220 and the defrosting chamber 230 are naturally cooled by heat conduction, and after a period of time, the temperature of the thermostatic chamber 220 and the defrosting chamber 230 is similar to that of the refrigerating compartment 210. At this time, the air circulation path of the freezing chamber is as follows:

refrigerated evaporator 211 → refrigerated compartment 210 → refrigerated evaporator 211.

When the thawing function is started, the heating component 221 in the thermostatic chamber 220 is started to heat the thermostatic chamber 220, and when the first temperature sensor of the thermostatic chamber 220 measures that the thermostatic chamber 220 reaches a first preset temperature, the heating component 221 is closed, the fan 311 is started, and the air door 321 is started, specifically, the fan 311 conveys the gas in the refrigerating chamber 210 into the thermostatic chamber 220 through the first channel 310, so that the gas in the refrigerating chamber 210 and the gas in the thermostatic chamber 220 are mixed to form mixed gas, and the air door 321 makes the mixed gas enter the thawing chamber 230 through the second channel 320, so as to thaw meat in the thawing chamber 230. The air circulation path of the freezing chamber is as follows:

the refrigerating evaporator 211 → the refrigerating compartment 210 → the fan 311 → the thermostatic compartment 220 → the damper 321 → the thawing compartment 230 → the second return duct 340 → the refrigerating compartment 210 → the refrigerating evaporator 211.

When the temperature of the thermostatic chamber 220 is lower than the start-up point of the heating assembly 221, that is, when the first temperature sensor of the thermostatic chamber 220 measures that the thermostatic chamber 220 is lower than the first preset temperature, the fan 311 and the air door 321 are closed, the heating assembly 221 is opened, and the heating of the thermostatic chamber 220 is continued until the thermostatic chamber 220 reaches the stop point temperature. At this time, since the air naturally flows, the air in the thermostatic chamber 220 can circulate through the first air return duct 330 and the first channel 310 and the refrigerating compartment 210, so that the air in the thermostatic chamber 220 is uniformly heated.

According to the thawing method, the fan, the damper and the heating assembly are alternately opened, and the temperature circulating to the thawing chamber reaches the shutdown point, i.e., when the second temperature sensor of the thawing chamber measures that the thawing chamber is lower than the second preset temperature, the thawing process is ended. And the temperature of the thawing chamber is controlled at-3 ℃ after the thawing procedure is finished in order to ensure the meat quality after thawing.

In order to ensure the thawing temperature uniformity of meat in the thawing process and ensure the meat quality, the steel wire shelf with lower heat conductivity coefficient is arranged at the position of the thawing chamber close to the bottom, so that the problem caused by the inconsistent thawing speed of the upper surface and the lower surface of the thawing chamber in the thawing process is solved.

The thermostatic chamber is generated by the circulating action of the heating assembly and the air door of the fan in a matching way, the problem of temperature fluctuation of the thermostatic chamber is effectively solved by dynamic control, and the temperature stability is greatly improved. The invention adopts the fan to supply air for unfreezing, has the advantages of rapidness and high efficiency, and simultaneously avoids the problems of nutrient loss, quality reduction and the like in the unfreezing process. According to the invention, when the thawing finishing temperature is-3 ℃, namely the second preset temperature is-3 ℃, namely the thawing chamber is below-3 ℃, the mixed gas is stopped being input into the thawing chamber, so that the excessive thawing condition can not occur even after the thawing is finished, and the use experience of a user is improved.

The invention provides a constant-temperature unfreezing system of a refrigerator, which meets the creation of a constant-temperature chamber by using a relatively simple structure and a control program and creates conditions for constant-temperature unfreezing. The invention provides an air circulation path of an air-cooled refrigerator, which achieves the purpose of air-cooled constant-temperature thawing through the program control of a Dieuler and an air door, so that the meat thawing process is faster, and the meat is free of bloody water and pollution in the thawing process. The invention provides the application of the steel wire shelf in the thawing chamber, so that meat is thawed more uniformly and better in effect.
