In practice, the air duct 118 is defined by the second cover plate 114, the first cover plate 115 and the components therebetween. Fig. 3 is a rear view of an air-cooled refrigerator according to one embodiment of the present application with the rear wall of the refrigerated compartment 110 removed. The rear wall of the refrigerated compartment 110 may be part of the cabinet 101 of the air-cooled refrigerator 100. Referring to fig. 3, after the rear wall of the refrigerating compartment 110 is removed, the air-cooled refrigerator 100 is sequentially provided with an evaporator 113 and a second cover plate 114, that is, the evaporator 113 is located between the second cover plate 114 and the rear wall of the refrigerating compartment 110, a space therein is a space refrigerated by the evaporator 113 and is an evaporator compartment, the first cover plate 115 is a front cover plate of an air duct 118 of the air-cooled refrigerator 100, and the second cover plate 114 is a rear cover plate of the air duct 118 of the air-cooled refrigerator 100.

Fig. 5 is a side view of a first cover plate of an air-cooled refrigerator according to an embodiment of the present application, fig. 6 is an exploded view of an air duct of the air-cooled refrigerator according to an embodiment of the present application, and fig. 7 is an exploded view of the first cover plate and air duct foam of the air-cooled refrigerator according to an embodiment of the present application. The air duct 118 of the air-cooled refrigerator is provided with at least one air outlet and at least one air inlet. Specifically, referring to fig. 5, fig. 6 and fig. 7, the air outlet 1152 disposed on the side wall of the first cover 115 of the air duct 118 specifically includes four air outlets, namely a first air outlet 11521, a second air outlet 11522, and a third air outlet and a fourth air outlet, where the third air outlet and the fourth air outlet are not shown in the drawing, and they may be disposed on the side wall of the first cover 115 that is symmetrical to the side wall of the first air outlet 11521, and are symmetrically disposed on the first air outlet 11521 and the second air outlet 11522, respectively. The air outlet 1152 formed on the sidewall of the first cover plate 115 of the duct 118 is in communication with the refrigerating compartment 111, so that cool air can enter the refrigerating compartment 111 through the air outlet 1152.

With continued reference to fig. 6 and 7, the air duct 118 is limited between the first cover plate 115 and the second cover plate 114, the air duct foam 116 is included between the first cover plate 115 and the second cover plate 114, and most of the air duct 118 is limited by the air duct foam 116. The air duct foam 116 includes a first air duct opening 1161, a second air duct opening 1162, a third air duct opening 1163, and a fourth air duct opening 1164, which are outlets for delivering air to the outside of the air duct 118 limited by the air duct foam 116, and may respectively correspond to the first air outlet 11521, the second air outlet 11522, the third air outlet, and the fourth air outlet, that is, the cool air at the first air duct opening 1161 is delivered to the first air outlet 11521, the cool air at the second air duct opening 1162 is delivered to the second air outlet 11522, and so on, so that the cool air entering the air duct 118 may be delivered to the air outlet 1152 and then enter the refrigerating compartment 111. An air inlet matching part 1165 and a fan embedding part are further formed in the air duct foam 116 through structural limitation, a fan 1167 is embedded in the fan embedding part, and the air inlet matching part 1165 is a main passage through which cold air driven by the fan 1167 flows to each air duct opening. The second cover plate 114 of the air duct 118 is provided with a fan air inlet channel port 1141 and an air inlet port 1142, which are matched with the fan 1167, the air inlet port 1142 is used for conveying cold air to the air duct 118, and the air inlet port 1142 is embedded in the air inlet matching portion 1165 in the air duct foam 116 and is matched with the air inlet matching portion 1165, so that the air inlet port 1142 serves as a main passage through which the cold air driven by the fan 1167 flows to each air duct port. Under the driving of the fan 1167, the cool air is input to the air inlet 1142 through the fan inlet 1141, and then is delivered to each air duct through each air duct path.

In addition, referring to fig. 6 and 7, the first cover plate 115 of the air duct 118 further includes an air return port 1153. Thus, based on the above structure, the refrigerating compartment 111 of the air-cooled refrigerator 100 can realize the refrigerating cycle process in the normal mode, which is mainly as follows:

1. the evaporator 113 cools the air of the evaporator compartment, thereby forming cold air;

2. the cold air in the evaporator bin enters the air duct 118 limited by the air duct foam 116 through the fan air inlet channel port 1141;

3. driven by the fan 1167, the cold air enters the air inlet 1142 and is conveyed to each air duct opening through each air duct path, and is conveyed into the refrigerating chamber 111 from the air outlet 1152;

4. and partial air in the refrigerating chamber 111 enters the evaporator bin through the air return port 1153 to be refrigerated again.

Although the above-described structure can already realize the refrigeration function of refrigerating compartment 111, for example, air inlet 1142 or air outlet 1152 is an openable damper, and the refrigeration is realized by timing opening and closing of air inlet 1142 or air outlet 1152, in order to realize the temperature adjustment in refrigerating compartment 111 or to keep the temperature in refrigerating compartment 111 within a stable range, so that refrigerating compartment 111 has the normal refrigeration function, a temperature sensing component, for example, a temperature sensing head, for sensing the temperature of refrigerating compartment 111 is usually provided to sense the temperature of refrigerating compartment 111, and at the same time, air outlet 1152 or air inlet 1142 is provided as an openable damper, or both air outlet 1152 and air inlet 1142 are provided as openable dampers, and the opening and closing of air outlet 1152 and/or air inlet 1142 is controlled by the temperature sensing component according to the sensed temperature. Referring to fig. 5 and 6, the temperature sensing member 1151 is disposed on the sidewall of the first cover 115, and the first cover 115 is assembled such that the temperature sensing member 1151 of the sidewall is in contact with the air in the refrigerating compartment 111. In this way, when the normal mode of the refrigerating compartment 111 is started, the refrigerating compartment 111 can be temperature-regulated through the process of:

1. if the temperature sensed by the temperature sensing part 1151 reaches a first temperature, for example, 6 degrees celsius, the air outlet 1152 and/or the air inlet 1142 is opened, and cool air is delivered to the refrigerating compartment 111 through the air outlet 1152, and enters the refrigerating compartment 111 to refrigerate the refrigerating compartment 111. At this time, the opening of the air outlet 1152 and the air inlet 1142 may be the following situations: first, only the air outlet 1152 is an openable air door, the air inlet 1142 is an open fixed solid structure, and the air outlet 1152 is opened; secondly, only the air inlet 1142 is an openable air door, the air outlet 1152 is an open fixed solid structure, and the air inlet 1142 is opened; third, the air inlet 1142 and the air outlet 1152 are both openable air doors, and the air inlet 1142 and the air outlet 1152 are both opened.

2. If the temperature sensed by the temperature sensing member 1151 is lower than a second temperature, for example, 1 degree celsius, the air outlet 1152 and/or the air inlet 1142 is closed, the cold air can not enter the refrigerating compartment 111 through the air outlet 1152 and/or the air inlet 1142, and the refrigerating compartment 111 is heated, wherein the first temperature is greater than or equal to the second temperature. At this time, the closing of the air outlet 1152 and the air inlet 1142 may be the following situations: first, only the air outlet 1152 is an openable air door, the air inlet 1142 is an open fixed solid structure, and the air outlet 1152 is closed; secondly, only the air inlet 1142 is an openable air door, the air outlet 1152 is an open fixed solid structure, and the air inlet 1142 is closed; third, the air inlet 1142 and the air outlet 1152 are both openable air doors, and both the air inlet 1142 and the air outlet 1152 are closed, or any one of the air inlet 1142 and the air outlet 1152 is closed.

Specifically, the air-cooled refrigerator 100 is further provided with a temperature sensing part micro-wind hole for cooling the temperature sensing part 1151, the temperature sensing part micro-wind hole is arranged close to the temperature sensing part 1151, and the temperature sensing part micro-wind hole is an openable and closable air door; when the normal mode of the refrigerating chamber 111 is started, the temperature sensing part breeze hole is closed; when the constant temperature mode of the refrigerating chamber 111 is started, the breeze hole of the temperature sensing part is opened, the temperature sensing part 1151 is cooled and air is supplied to the refrigerating chamber 111, the temperature sensed by the temperature sensing part 1151 is lower than the second temperature, so that the air outlet 1152 and/or the air inlet 1142 is closed, at the moment, cold air in the evaporator bin can not be conveyed into the refrigerating chamber 111 through the air outlet 1152, the refrigerating chamber 111 only receives the cold air from the breeze hole of the temperature sensing part, therefore, temperature fluctuation of the refrigerating chamber 111 is eliminated, and the temperature in the refrigerating chamber 111 is constant. In a normal mode, when the temperature sensed by the temperature sensing part 1151 is lower than the second temperature, the air outlet 1152 and/or the air inlet 1142 is/are closed, so as to avoid further cooling the refrigerating chamber 111, and when the temperature fluctuation of the refrigerating chamber 111 is to be eliminated, the temperature sensing part 1151 is cooled through the micro air holes of the temperature sensing part, so that the temperature sensed by the temperature sensing part 1151 is lower than the second temperature, if the temperature fluctuation of the refrigerating chamber 111 is to be eliminated, the control logic in the normal mode is used continuously, and the temperature sensing part 1151 can control the air outlet 1152 and/or the air inlet 1142 to be closed.

The temperature sensing part breeze hole can be arranged at various relative positions with the temperature sensing part 1151, and only needs to be close to the temperature sensing part 1151 and communicated with the refrigerating chamber 111, for example, the temperature sensing part breeze hole can be obliquely arranged relative to the temperature sensing part 1151 and also can be arranged on the same straight line, so that the temperature sensing part breeze hole faces the temperature sensing part 1151, and the temperature sensing part 1151 can be rapidly cooled, the air outlet 1152 and/or the air inlet 1142 can be rapidly closed, and the temperature fluctuation of the refrigerating chamber 111 can be rapidly eliminated.

Fig. 8A is an exploded view of a trim panel and a first cover panel of an air-cooled refrigerator according to an embodiment of the present application. The air duct 118 of the air-cooled refrigerator 100 is provided with a plurality of breeze holes 1154, and the breeze hole of the temperature sensing part is one of the plurality of breeze holes 1154. Referring to fig. 8A, 8 groups of breeze holes 1154 are formed in the first cover plate 115 of the duct 118, and the breeze holes 1154 communicate with the refrigerating compartment 111 to supply cool air to the refrigerating compartment 111.

The manner in which the breeze holes 1154 communicate with the refrigerating compartment 111 may be various. Fig. 8B is a rear view of a decorative panel of an air-cooled refrigerator according to an embodiment of the present application. In some embodiments of the present application, please refer to fig. 8A and 8B, specifically, a decorative plate 117 is further disposed between the first cover plate 115 and the refrigerating compartment 111, a decorative hole 1171 corresponding to each of the breeze holes 1154 of the first cover plate 115 is further disposed on the decorative plate 117, and the cool air flowing out of the breeze holes 1154 enters the refrigerating compartment 111 through the decorative hole 1171. Since the first cover plate 115 is provided with the breeze holes 1154 and other components, the appearance of the first cover plate 115 is not good enough, and the decorative plate 117 including the decorative hole 1171 is arranged between the refrigerating chamber 111 and the first cover plate 115, so that the cold air flowing out of the breeze holes 1154 can flow into the refrigerating chamber 111, the appearance of the refrigerating chamber 111 is more beautiful, and the aesthetic requirement of a user is met. Of course, in order to further improve the appearance of the refrigerating compartment 111, some textures or patterns may be added to the decorative plate 117.

The mode for eliminating the temperature fluctuation of the refrigerating chamber 111 can be specifically a constant temperature mode, that is, the operation mode of the refrigerating chamber 111 includes a constant temperature mode, the operation mode of the refrigerating chamber is a specific working mode of the refrigerating chamber, the constant temperature mode is a mode which can be distinguished from the normal mode, that is, the constant temperature mode and the normal mode of the air-cooled refrigerator can be simultaneously realized by the air-cooled refrigerator. When the constant temperature mode of the refrigerating chamber 111 is started, the air outlet 1152 and/or the air inlet 1142 is closed, and cold air is delivered to the refrigerating chamber 111 through the breeze hole 1154, because no matter the air outlet 1152 or the air inlet 1142 is closed, the air outlet 1152 can not obtain cold air from the air inlet 1142, and further cold air can not be delivered to the refrigerating chamber 111 through the air outlet 1152, namely the breeze hole 1154 becomes the only inlet for delivering cold air to the refrigerating chamber 111, and because the ventilation area of the air source hole corresponding to the breeze hole 1154 is fixed, namely the ventilation area is continuously kept constant, all cold air entering the breeze hole 1154 comes from the corresponding air source hole, so that the temperature in the refrigerating chamber 111 is kept constant.

Because the sum of the ventilation areas of the air outlet 1152 and the air inlet 1142 or the sum of the ventilation areas of the air outlets 1152 and the air inlets 1142 is usually set to be larger so as to meet the requirement of rapidly cooling the refrigerating chamber 111 in the normal mode, the sum of the ventilation areas of the air outlet 1152 and the air inlet 1142 or the sum of the ventilation areas of the air outlet 1152 and the air inlets 1142 is usually larger, and the sum of the ventilation areas of the air outlets 1152 and the air inlets 1142 is larger than the sum of the ventilation areas of the breeze holes 1154, so that the refrigerating chamber 111 can still be kept in a reasonable temperature range in the constant temperature mode, and the constant temperature of the refrigerating chamber 111 is neither too high nor too low. For example, the temperature set in the constant temperature mode of the refrigerating compartment 111 is generally between the first temperature and the second temperature corresponding to the normal mode of the refrigerating compartment 111.

Therefore, this not only eliminates the temperature fluctuation of the refrigerating compartment 111, but also further allows the refrigerating compartment 111 to be thermostated.

Referring to fig. 7, the air duct 118 further has an air inlet hole 1166 corresponding to the breeze hole 1154, in this case, the air inlet hole 1166 is an air source hole, and the air inlet 1142 is an openable and closable damper, that is, the ventilation area of the air inlet hole 1166 is fixed. When the constant temperature mode of the refrigerating chamber 111 is started, the air inlet 1142 is closed, and cold air is delivered to the micro air holes 1154 through the air inlet holes 1166, so that temperature fluctuation of the refrigerating chamber 111 is eliminated, and the constant temperature mode of the refrigerating chamber 111 is realized, and an independent air channel can be arranged in an air path between each micro air hole 1154 and the corresponding air inlet hole 1166, or the air channel 118 used for refrigerating the refrigerating chamber 111 in a normal mode can be passed through.

In some embodiments of the present application, each of the breeze holes 1154 is an openable and closable damper, and when the constant temperature mode of the refrigerating compartment 111 is activated, the air outlet 1152 and/or the air inlet 1142 is closed, and the breeze hole 1154 is opened to deliver cool air to the refrigerating compartment 111 through the breeze hole 1154.

In some embodiments, each of the air inlet holes 1166 is an openable damper.

In the normal mode, the breeze hole 1154 and/or the air inlet 1166 may be opened or closed, so that the air duct 118 used in the constant temperature mode is opened or closed, the air duct 118 used in the constant temperature mode is opened without significantly affecting the normal mode, and the temperature fluctuation in the normal mode may be reduced, so that the air duct used in the constant temperature mode may be used in the normal mode.

In some embodiments of the present application, the air outlet 1152 is an openable and closable air door, and the air inlet 1142 of the air duct 118 is an air source hole corresponding to the breeze hole 1154, that is, the cool air of the breeze hole 1154 comes from the air inlet 1142, when the constant temperature mode of the refrigerating chamber 111 is started, the air outlet 1152 is closed, and the cool air is delivered to the breeze hole 1154 through the air inlet 1142, so as to deliver the cool air to the refrigerating chamber 111 through the breeze hole 1154.

The present embodiment eliminates the temperature fluctuation of the refrigerating compartment 111 and realizes the constant temperature mode of the refrigerating compartment 111 in another way.

The number, shape, size and position of the micro-vents 1154 may be arbitrarily set according to design requirements, the temperature of the constant temperature to be achieved, the size and layout of the space of the refrigerating compartment 111.

Since the air inlet 1142 of the air chute 118 is an air source hole corresponding to the breeze hole 1154, the ventilation area of the air inlet 1142 of the air chute 118 is fixed in the constant temperature mode. In the normal mode, the air inlet 1142 of the air duct 118 is kept open, and may be an openable damper or an open fixed solid structure, and the temperature of the refrigerating compartment 111 is adjusted by opening and closing the air outlet 1152.

In some embodiments of the present application, the refrigerated compartment 111 includes a plurality of sub-chambers, each sub-chamber communicating with at least one breeze aperture 1154.

When the refrigerating chamber comprises a plurality of sub-chambers, if the refrigerating chamber is communicated with only one breeze hole, the constant temperature in the chamber is difficult to realize quickly and uniformly. Thus, the present embodiment achieves a constant temperature mode under multiple sub-chambers.

For example, referring to fig. 2B, the refrigerating compartment 111 includes a plurality of spaces, and each space may be a sub-compartment.

In some embodiments of the present application, the box body 101 of the air-cooled refrigerator 100 further includes a base for placing the air-cooled refrigerator 100, and the sub-chambers are arranged in layers, and the sum of the ventilation areas of the micro-air holes communicated with the sub-chambers increases gradually in sequence from the direction close to the base to the direction far away from the base.

The sum of the ventilation areas of the breeze holes communicated with the sub-chambers which are sequentially increased in the direction from the position close to the base to the position far away from the base can be set according to a certain mathematical rule or set according to experiments or experience.

Because the easy lower floor of cold air, so when the breeze hole evenly sets up, the subchamber of lower floor obtains more cold air easily for in the short time after getting into the constant temperature mode, the subchamber temperature of lower floor is lower relatively. The lower the base is closer to, highly is more far away from the base, highly more highly, consequently, in the direction from being close to the base to keeping away from the base, make the sum of the ventilation area of the breeze hole that each subchamber communicates increase gradually in proper order for the subchamber on upper strata obtains more cold air, and when cold air sinks, each subchamber also can keep even temperature.

In some embodiments, the breeze holes 1154 are dampers with adjustable opening areas, and the sum of the ventilation areas of the air outlets 1152 and the sum of the ventilation areas of the air inlets 1142 are both greater than the sum of the adjustable maximum opening areas of the breeze holes 1154.

Similarly, the air inlet hole 1166 may also be an air door with an adjustable opening area.

The breeze holes 1154 may be air doors designed based on various principles, and only the opening area of the breeze holes is required to be kept fixed after adjustment while the opening area is adjustable, for example, the breeze holes may be electric air doors having an open engaging gear, or air doors constructed by using a mechanical plectrum principle, and the opening area of the breeze holes 1154 may be kept constant continuously by these types of air doors.

The constant temperature adjustment in the constant temperature mode is realized, and in addition, under the condition that the air door with the adjustable opening area is adopted as the micro air hole, the temperature of the refrigerating chamber in the constant temperature mode can be kept in a reasonable range.

The embodiment of the application provides an air-cooled refrigerator can make the temperature operating curve in the freezer as shown in fig. 1B, can be so that the temperature operating curve in the freezer is similar to second temperature operating curve B, and under this state, the temperature keeps invariable in the freezer, eliminates the fluctuation of the freezer internal temperature of air-cooled refrigerator, has improved fresh-keeping effect.
