Background
In the field of refrigerators of today, air-cooled refrigerators have an increasing market share due to the fact that they have a faster refrigeration speed and can solve the problem of manual defrosting. In a common air-cooled refrigerator, the cold energy required by the refrigerating chamber is from the cold energy in the freezing evaporator, and the cold energy is blown out from a refrigerating air duct at the rear part of the refrigerating chamber and enters the refrigerating chamber through an air outlet to cool the food in the refrigerating chamber. However, the air circulating in the refrigerating duct comes directly from the evaporator and is therefore at a relatively low temperature, whereas the refrigerating chamber is at a relatively high temperature, typically 2 to 8 ℃. Then, in order to prevent condensation on the duct cover, it is generally necessary to provide a foam insulation material between the refrigerating duct and the refrigerating chamber with a thickness of typically 10 to 15 mm. And, because the refrigerating air duct already occupies a part of the refrigerating chamber space, the refrigerating chamber space is small.
Therefore, a refrigerator which does not need an insulating layer and can prevent condensation on the air duct cover plate must be designed.

Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
As shown in fig. 1 to 2, the present invention provides a refrigerator 100, where the refrigerator 100 includes a box body (not numbered), a refrigerating liner 1, a freezing liner 2 and a refrigerating system, which are disposed in the box body, the refrigerator 100 further includes a refrigerating air duct 10 for conveying cold air to the refrigerating liner 1, and a freezing air duct 20 for conveying cold air to the freezing liner 2, of course, the refrigerating liner 1 and the freezing liner 2 are respectively provided with an air port 21 communicated with the refrigerating air duct 10 and the freezing air duct 20, and the refrigerating air duct 10 is communicated with the freezing air duct 20. The refrigerating system comprises a compressor, a condenser, an evaporator 3, an air supply fan 4 and an air mixing fan 5, wherein the evaporator 3 and the air supply fan 4 are both arranged in a freezing air duct 20. Therefore, the air supply fan 4 can blow the cold energy in the evaporator 3 to the freezing liner 2 through the freezing air duct 20, and can also blow the cold energy to the refrigerating liner 1 through the refrigerating air duct 10 communicated with the freezing air duct 20.
The refrigerator 100 further comprises an air mixing duct 51, one end of the air mixing duct 51 is communicated with the refrigerating liner 1, the other end of the air mixing duct 51 is communicated with the refrigerating duct 10, and an air mixing fan 5 is arranged in the air mixing duct 51. The air mixing fan 5 can blow the air with relatively high temperature in the refrigerating liner 1 into the air mixing duct 51, and blow the air into the refrigerating duct 10 to be fully mixed with the air with relatively low temperature in the refrigerating duct 10. The air temperature in the refrigerating air duct 10 is correspondingly increased, and the temperature difference between the air and the air in the refrigerating inner container 1 is also reduced, so that condensation cannot be generated on the air duct cover plate, a thick heat insulation layer does not need to be arranged on the air duct cover plate, and the space of the refrigerating inner container 1 is correspondingly increased.
In the present embodiment, the air mixing fan 5 is a centrifugal fan. The centrifugal fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draught of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grains; wind tunnel wind source and air cushion boat inflation and propulsion.
In addition, in the present embodiment, the refrigerating duct 10 includes a wind mixing chamber 11 provided near the freezing duct 20, and the wind mixing duct 51 communicates with the wind mixing chamber 11. The air mixing chamber 11 is formed in the refrigerating duct 10 and protrudes a distance toward the refrigerating liner 1 so that the width of the air mixing chamber 11 is greater than that of the refrigerating duct 10. Because the air mixing chamber 11 is formed at one end of the refrigerating air duct 10 close to the freezing air duct 20, the cold air in the freezing air duct 20 and the air with higher temperature in the air mixing air duct 51 are fully mixed in the air mixing chamber 11 and flow to other positions in the refrigerating air duct 10, and finally flow into the refrigerating inner container 1 through the air opening 21. The air mixing chamber 11 is internally provided with a first temperature sensor 12 for detecting the temperature in the air mixing chamber 11, and the temperature in the air mixing chamber 11 can be sensed in real time through the first temperature sensor 12, so that the air supply fan 4 and the air mixing fan 5 are controlled, the temperature in the air mixing chamber 11 is kept in a certain range, the temperature in the air mixing chamber 11 is not overheated, and the air duct cover plate is not condensed. The detailed description of the control method is omitted here, and the detailed description is given later in the control method of the refrigerator 100.
The refrigerator 100 further includes an air door 6 disposed between the refrigerating air duct 10 and the freezing air duct 20, when the air door 6 is opened, cold air in the freezing air duct 20 can be blown into the refrigerating air duct 10, and when the air door 6 is closed, cold air in the freezing air duct 20 cannot be blown to the past. So as to prevent the temperature in the refrigerating inner container 1 from being too low and further reduce the temperature.
Of course, the refrigerator 100 further includes a return air duct 7, wherein one end of the return air duct 7 is communicated with the refrigerating inner container 10, and the other end is communicated with the freezing air duct 20. Of course, the end of the return air duct 7 communicating with the freezing air duct 20 is disposed at the inlet end of the evaporator 3, so that the return air with higher temperature in the refrigerating liner 1 can be cooled again through the evaporator 3 and circulated into the refrigerating liner 1 again. The return air duct 7 is independent of the refrigerating air duct 10 and is not communicated with the refrigerating air duct 10.
The invention also discloses a control method of the refrigerator 100. The control method of the refrigerator 100 includes:
the air supply fan 4 is turned on;
the cold energy in the freezing air duct 20 is blown to the refrigerating air duct 10 through the air supply fan 4, and meanwhile, the air mixing fan 5 is started to blow the air in the refrigerating liner 1 to the air mixing air duct 51;
the air in the air mixing duct 51 is mixed with the cold air in the refrigerating duct 10, and is delivered into the refrigerating liner 1.
Specifically, as described above, the refrigerating air duct 10 includes the air mixing chamber 11 disposed close to the freezing air duct 20, and the air mixing air duct 51 is communicated with the air mixing chamber 11, after the air mixing fan 5 blows relatively high-temperature air in the refrigerating liner 1 into the air mixing air duct 51, the air in the air mixing air duct 51 is blown into the air mixing chamber 11 again, and meanwhile, cold air in the freezing air duct 20 is also blown into the air mixing chamber 11 and mixed. Therefore, the cold air with low temperature in the freezing air duct 20 and the original air with high temperature in the refrigerating liner 1 are fully mixed in the air mixing chamber 11, so that the temperature of the cold air is relatively increased, and two air streams from different places can be fully mixed due to the structural design of the air mixing chamber 11.
In addition, as described above, the refrigerator 100 further includes the damper 6 disposed between the refrigerating duct 10 and the freezing duct 20, and of course, the damper 6 is also disposed between the air mixing chamber 11 and the freezing chamber. The step of blowing the cold in the freezing air duct 20 to the cold storage air duct 10 by the air supply fan 4 includes: the air door 6 is opened, so that the cold in the freezing air duct 20 is blown to the cold storage air duct 10 through the air supply fan 4. Specifically, a second temperature sensor (not shown) for detecting the temperature in the refrigerating liner 1 is arranged in the refrigerating liner 1, and when the second temperature sensor senses that the temperature in the refrigerating liner 1 is greater than a third temperature threshold value, it indicates that the temperature in the refrigerating liner 1 is too high, and then the air door 6 is opened, so that the cold energy in the freezing air duct 20 can be transmitted to the refrigerating liner 1; when the second temperature sensor senses that the temperature in the refrigerating liner 1 is lower than the fourth temperature threshold value, it indicates that the temperature in the refrigerating liner 1 is too low, and the air door 6 is closed. Therefore, the air door 6 controls the refrigeration condition in the refrigerating liner 1, and prevents the temperature in the refrigerating liner 1 from being too high or too low, so that the temperature in the refrigerating liner 1 is kept in a stable range. However, in the control method of the refrigerator 100 of the present invention, since the air mixing condition in the air duct of the refrigerator 100 is mainly controlled, the default is the condition that the damper 6 is opened, and the details are not repeated when the damper 6 is closed. The values of the third temperature threshold and the fourth temperature threshold are determined by the placement position of the second temperature sensor and the installation of the thermostat, and normally, the third temperature threshold is 10 ℃ and the fourth temperature threshold is-2 ℃.
In the control method of the refrigerator 100 of the present invention, in order to accurately control the air mixing condition, the air mixing chamber 11 of the refrigerator 100 of the present invention is further provided with a first temperature sensor 12 for detecting the temperature of the air mixing chamber 11. Accordingly, the control method of the refrigerator 100 further includes: when the temperature sensed by the first temperature sensor 12 is lower than a first temperature threshold, reducing the rotation speed of the air supply fan 4, or closing the air supply fan 4, or opening the air mixing fan 5, or increasing the rotation speed of the air mixing fan 5; on the contrary, if the temperature sensed by the first temperature sensor 12 is higher than the second temperature threshold, the rotation speed of the air supply fan 4 is increased, or the air supply fan 4 is turned on, or the rotation speed of the air mixing fan 5 is decreased, or the air mixing fan 5 is turned off. Specifically, because the rotational speed of the air supply fan 4 can also influence the refrigeration effect in the freezing chamber, in this embodiment, the air supply fan 4 is not adjusted, but when the temperature sensed by the first temperature sensor 12 is lower than the first temperature threshold, the air mixing fan 5 is turned on, and when the temperature sensed by the first temperature sensor 12 is higher than the second temperature threshold, the air mixing fan 5 is stopped, so that the temperature in the air mixing chamber 11 is stabilized in a certain range, and the frosting of the air duct cover plate is prevented. Specifically, the first temperature threshold is-5 ℃, the second temperature threshold is 0 ℃, and the temperature in the air mixing chamber 11 is stabilized in the range of-5 to 0 ℃.
Therefore, in summary, the control method of the refrigerator 100 specifically includes:
the air supply fan 4 is turned on;
a second temperature sensor in the refrigerating liner 1 senses the temperature, when the sensed temperature is greater than a third temperature threshold value, the air door 6 is opened, the cold energy in the evaporator 3 is transmitted into the refrigerating liner 1 through the air supply fan 4, and the refrigerating liner 1 is refrigerated;
a first temperature sensor 12 in the air mixing chamber 11 senses the temperature, and when the sensed temperature is lower than a first temperature threshold value, the air mixing fan 5 is turned on, so that the original air with higher temperature in the refrigerating liner 1 reaches the air mixing chamber 11 through the air mixing air duct 51, is fully mixed with the cooler air in the freezing air duct 20 in the air mixing chamber 11, and is blown out to the refrigerating air duct 10 along the refrigerating air duct 10; on the contrary, when the sensed temperature is higher than the second temperature threshold, the air mixing fan 5 is turned off, so that the cold air in the freezing air duct 20 directly enters the refrigerating air duct 10 and blows into the refrigerating inner container 1.
Therefore, in summary, by the above method, the air blown to the refrigerating liner 1 can be stabilized within a certain range, the temperature difference between the air and the refrigerating liner 1 is small, and the condensation is not generated enough, and the air duct cover plate does not need to be provided with a heat insulation layer, so that the space of the refrigerating liner 1 can be increased.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
