Below with reference to the refrigerator of accompanying drawing description according to the embodiment of the invention.
Shown in Fig. 1-4, refrigerator comprises according to an embodiment of the invention: casing 10, compressor 20, evaporimeter (not shown), dividing plate 40, and humidifying unit.
Casing 10 comprises housing 101 and the case courage 102 that is arranged in the housing 101, is limited with refrigerating chamber 1021 in its raising middle flask courage 102.
Compressor 20 is located at the back side lower part of described refrigerator.
Described evaporimeter is between case courage 102 and housing 101 and give refrigerating chamber 1021 refrigeration.
Dividing plate 40 is located in the refrigerating chamber 1021 and is limited with container cavity 400 between dividing plate 40 and case courage 102, and an end of dividing plate 40 is formed with air admission hole 401 and the other end is formed with vapor opening 402.
Described humidifying unit is arranged in the container cavity 400 and by the air in the air admission hole 401 suction refrigerating chambers 1021 and by vapor opening 402 and is blown into atomized steam in refrigerating chamber 1021.
Refrigerator according to the embodiment of the invention, described humidifying unit is blown into atomized steam with to refrigerating chamber 1021 humidifications by vapor opening 402 in refrigerating chamber 1021, can make the humidity and the humidity that keep higher in the refrigerating chamber 1021 more stable, can be so that better to the fresh-keeping effect of vegetables, fruit.
Shown in Fig. 1-2, according to one embodiment of present invention, described humidifying unit comprises: heat exchanger 501, the water receiving tank 502 and first fan 503 and second fan 504.
Heat exchanger 501 is across the 102 adjacent settings with described evaporimeter of case courage.
Water receiving tank 502 is positioned at heat exchanger 501 belows and accepts the defrost water that heat exchanger 501 produces.
First fan 503 and air admission hole 401 are adjacent and be set to the air in the refrigerating chamber 1021 is sucked in the container cavity 400, and the adjacent and defrost water smoke that be set to accept in the water receiving tank 502 of second fan 504 and venthole 402 turns to steam and is blown into steam by venthole 402 in refrigerating chamber 1021.Thus, the defrost water that can form air circulation between refrigerating chamber 1021 and container cavity 400 and can utilize heat exchanger 501 to produce easily carries out humidification to refrigerating chamber 1021, need not manually to add water.
Advantageously, as shown in Figure 3-4, thereby increase heat exchanger effectiveness in order to increase heat exchange area, heat exchanger 501 is a fin heat exchanger.
According to one embodiment of present invention, described humidifying unit also comprises siphon parts 505, and first end of siphon parts 505 links to each other with water receiving tank 502 and second end links to each other with venthole 402.Thus, can increase the specific area of defrost water, improve nebulization efficiency.
Advantageously, siphon parts 505 are second end covering vapor opening 402 of porous water-absorbing cloth and siphon parts 505.Alternatively, siphon parts 505 are second end covering vapor opening 402 of water-absorbing sponge or feltwork body and siphon parts 505.Thus, siphon parts 505 can be covered with vapor opening 402 with defrost water by capillarity, further improve nebulization efficiency, can strengthen the humidification effect to refrigerating chamber 1021.
According to some embodiments of the present invention, described humidifying unit also comprises water receiving pipe 506, and first end of water receiving pipe 506 is connected with the bottom of heat exchanger 501 and second end of water receiving pipe 506 is connected with water receiving tank 502.Thus, the defrost water that heat exchanger 501 is produced can be inserted in the water receiving tank 502 easily.
According to an example of the present invention, described humidifying unit also comprises overflow pipe 507, and an end of overflow pipe 507 is communicated with water receiving tank 502 and the other end extends outside the housing 101.Thus, can keep the water yield in the water receiving tank to maintain below the scheduled volume also with excessive defrost water discharge water receiving tank 502.
According to concrete example of the present invention, described humidifying unit also comprises Humidity Detection unit (not shown) and humidifier controller (not shown).
Described Humidity Detection unit links to each other with refrigerating chamber 1021 and detects humidity in the refrigerating chamber 1021.
The humidity value that described humidifier controller is detected according to described Humidity Detection unit is controlled the opening and closing of first fan 503 and second fan 504.Thus, the opening and closing that can control described humidifying unit according to the humidity lower limit in the refrigerating chamber 1021 and higher limit, thus can save energy consumption.
Do not have special regulation about described upper limit humidity value and lower limit humidity value, can set according to the substance characteristics of being preserved, for example described upper limit humidity value can be set at 90%, and described lower limit humidity value can be set at 70%.That is to say that when described Humidity Detection unit detects humidity value in the refrigerating chamber 1021 greater than 90% the time, described Humidity Detection unit sends instruction so that described humidifier controller cuts out described first fan 503 and second fan 504; And detect humidity value in the refrigerating chamber 1021 less than 70% the time when described Humidity Detection unit, described Humidity Detection unit sends instruction so that described humidifier controller is opened described first fan 503 and second fan 504, at this moment, air in the refrigerating chamber 1021 is introduced in the container cavity 400 by first fan 503, and the defrost water on second end of the siphon parts 505 of covering vapor opening 402 is blown in the refrigerating chamber 1021 after being atomized by second fan 504.Thus, can make to keep higher humidity in the refrigerating chamber 1021, help being placed on the particularly fresh-keeping storage of vegetables, fruit etc. of article in the refrigerating chamber 1021.And, the humidity in the refrigerating chamber 1021 is kept relative stability.This is to understand easily for the person of ordinary skill of the art.
According to examples more of the present invention, described refrigerator also comprises the control system (not shown), and when compressor 20 was opened, described control system controls described first fan 503 and second fan 504 is opened; When compressor 20 cut out, described control system was controlled described first fan 503 and second fan 504 cuts out.
Need to prove that at this airborne steam runs into the cryogenic refrigeration sheet and congeals into ice and cause air humidity to descend when compressor is opened refrigeration; The cooling piece temperature is recovered temperature of refrigerating chamber after the compressor shutdown, and the water in air steam is not condensing, and humidity can remain on higher level.This is understandable to those skilled in the art.
In sum, control system by refrigerator is opened first fan 503 and 504 pairs of refrigerating chamber 1021 humidifications of second fan when compressor 20 starts, and when compressor 20 cuts out, close first fan 503 and 504 pairs of refrigerating chamber 1021 humidifications of second fan, therefore can save energy consumption significantly under the situation of the humidity environment in guaranteeing refrigerating chamber 1021.
Employing is according to the refrigerator of the embodiment of the invention, the indoor humidity of refrigerator cold-storage can reach 80% and more than, and, utilize defrost water humidification, need not artificial supplementation moisture.
