The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The refrigerator in the application is an air-cooled refrigerator, and a refrigerating system comprises a compressor, a condenser, an evaporator, a throttling device and the like.
The refrigerator in this application has a plurality of fresh-keeping drawers 500, and fan 600 blows the cold air that refrigerating system produced respectively to fresh-keeping drawer 500 in to keep the low temperature in the fresh-keeping drawer 500.
Referring to fig. 1 to 3, the refrigerator includes an inner container 100, the inner container 100 encloses a refrigerating chamber 110, a plurality of independent air channels 210 are provided in a foaming layer of the inner container 100 located at the rear side, and the plurality of air channels 210 are in one-to-one correspondence with the plurality of preservation drawers 500.
Specifically, a plurality of installation cavities 400 are arranged in the refrigerating chamber 110, and the installation cavities 400 are defined by plastic plates. The installation cavity 400 is open at the front side. Be equipped with fresh-keeping drawer 500 in installation cavity 400, fresh-keeping drawer 500 passes through slide isotructure and can pull for installation cavity 400 front and back to realize opening and closing of fresh-keeping drawer 500.
The rear side plate enclosed into the installation cavity 500 is provided with air inlets 410, and the air outlet 211 of each air duct is communicated with the corresponding air inlet 410, so that the fan 600 blows cold air into the corresponding installation cavity 400 through the air duct 210, the air outlet 211 of the air duct and the air inlet 410 in sequence, thereby realizing the low temperature corresponding to the preservation drawer 500.
One of the purposes of this application makes different fresh-keeping drawers 500 can keep different temperatures, realizes the fresh-keeping storage of different edible materials, improves the fresh-keeping effect of edible material.
In order to achieve the above purpose, in some embodiments of the present application, the air output of each air duct 210 is controlled to be different, that is, the amount of cold air delivered into the corresponding preservation drawer 500 through each air duct 210 is different, so that each preservation drawer 500 can have different temperatures to meet the preservation temperature requirements of different food materials.
In some embodiments of the present application, referring to fig. 2, a protrusion 230 is disposed in the air duct 210, and the protrusion 230 is used for limiting the amount of air supplied into the air duct 210. The size of the protrusion 230 will directly affect the amount of air delivered within the duct 210.
A fan installation cavity 220 is arranged in a foaming layer of the inner container 100 positioned at the rear side, and the air channels 210 are all communicated with the fan installation cavity 220. The fan is activated to blow airflow into the plurality of air ducts 210 simultaneously to achieve the cooling air requirements of the plurality of crisper drawers 500 simultaneously. Compared with a multi-fan, the single-fan structure is lower in cost. Meanwhile, the air supply amount control of different air ducts 210 can be realized by arranging the protruding part 230 in the air duct 210, and the structure is simple and easy to implement.
In some embodiments of the present application, referring to fig. 1 and 2, the crisper drawer 500 has a first crisper drawer 510 and a second crisper drawer 520, the first drawer 510 and the second drawer 520 being laterally juxtaposed. The set temperature of the first preservation drawer 510 is lower than the set temperature of the second preservation drawer 520, the air duct communicated with the first preservation drawer 510 is the first air duct 212, and the air duct communicated with the second preservation drawer 520 is the second air duct 213.
The air supply volume in the first air duct 212 is greater than the air supply volume in the second air duct 213, so that the amount of cold air entering the first preservation drawer 510 is greater than the amount of cold air entering the second preservation drawer 520, the temperature in the first preservation drawer 510 is lower than the temperature in the second preservation drawer 520, and the low-temperature preservation requirements of different food materials are met.
The protrusion 230 is disposed in the second air duct 213, and the protrusion 230 limits the amount of air supplied into the second air duct 213, so as to reduce the amount of air supplied into the second air duct 213, thereby controlling the temperature inside the second fresh-keeping drawer 520 communicated with the second air duct.
The set temperature range of the first fresh keeping drawer 510 is-2 + -0.5 deg.C, and the set temperature range of the second fresh keeping drawer 520 is 3-5 deg.C.
In some embodiments of the present application, each crisper drawer 500 has a different set temperature, and the first temperature sensor 300 is disposed in the air duct 210 communicated with the crisper drawer 500 having a low set temperature.
The air temperature in each air duct 210 can be converted by the air blowing amount and the air blowing speed of each air duct 210. The arrangement of a single temperature sensor is beneficial to reducing the cost.
Taking two preservation drawers 500 as an example, a first temperature sensor 300 is disposed in the first air duct 212 communicated with the first preservation drawer 510 with a lower set temperature.
There is cold volume loss at wind channel transportation process for air conditioning, locates the air outlet 211 department in wind channel with first temperature sensor 300, and what detect then for actually getting into the fresh-keeping drawer 500 in the air conditioning temperature, it is more accurate to detect data.
The preservation drawer with the lower set temperature generally requires smaller temperature fluctuation to ensure the food preservation effect. Taking the first preservation drawer 510 as an example, the set temperature of the first preservation drawer 510 is lower than zero, and precise temperature control is required to avoid the low temperature from affecting the internal texture and taste of the food material. Therefore, a second temperature sensor (not shown) is arranged in the preservation drawer with low set temperature, so that the precise control of the temperature is realized, and the preservation effect is ensured.
In some embodiments, each air duct 210 is provided with a damper, the damper in the first air duct 212 is labeled as a first damper 214, and the damper in the second air duct 213 is labeled as a second damper 215.
After the refrigerator works for a period of time, the evaporator frosts, and when the frosting amount reaches a certain value, the refrigerator enters a defrosting working mode to defrost the evaporator so as to improve the refrigerating effect and efficiency.
The evaporator is provided with a heating wire, the heating wire is electrified for heating, and the temperature near the evaporator is increased, so that defrosting of the evaporator is realized.
When defrosting, the air door is closed, that is to say, first air door 214 and second air door 215 are all closed to avoid in the steam gets into fresh-keeping drawer 500 through the wind channel and influence the low temperature in the fresh-keeping drawer, influence fresh-keeping effect.
After the refrigerator is switched from the defrosting operation mode to the refrigerating operation mode, the air door is opened again after the refrigerator works for a period of time in the refrigerating operation mode. This is because, after defrosting is finished, some hot air still exists in the air duct of the cold air circulation, after the refrigeration operation is performed for a period of time, the hot air still existing can be eliminated, and at this time, the air door is opened again, so that the low-temperature cold air entering the fresh-keeping drawer 500 can be ensured.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
