The stepped wall 116 is bent upward from the bottom wall 115 so as to form a stepped structure at the bottom of the receiving chamber 10 instead of a complete plane. Below the stepped wall 116, there is a pressing compartment 120, and it can be seen that the stepped wall 116 is basically arranged to give way to the pressing compartment 120, so as to optimize the structure of the refrigerator 100 and increase the space utilization of the refrigerator 100.

In the present embodiment, the stepped wall 116 is formed at the lower right portion of the inner container 11 in accordance with the position of the press machine room 120, and of course, if the position of the press machine room 120 is changed from the lower right portion of the box body 1 shown in the drawing to other positions, such as the lower left portion, the middle portion, the lower rear portion, and the like of the box body 1, the position of the stepped wall 116 is correspondingly changed from the lower right portion of the inner container 11 to other positions, such as the lower left portion, the middle portion, the lower rear portion, and the like of the inner container 11.

More specifically, step wall 116 includes a step top wall 1161 and a step side wall 1162. The lower end edge of the step side wall 1162 is connected to the bottom wall 115 of the inner container 11, and extends vertically upward from the right end edge of the bottom wall 115 approximately perpendicular to the bottom wall 115; step top wall 1161 is substantially perpendicular to step side wall 1162 and parallel to bottom wall 115, and step top wall 1161 extends rightward from the upper edge of step side wall 1162 until it is vertically connected to the lower edge of right side wall 114 of inner container 11. In this embodiment, step wall 116 is arranged in a right-angled configuration, but not limited thereto, for example, in a modified embodiment, step top wall 1161 and step side wall 1162 may be arranged in an obtuse angle or an acute angle, and step wall 116 may also be a fully curved plate without any significant boundary line.

In this embodiment, evaporator 33 is arranged in holding chamber 10, and freezer 100 sets up to the air-cooled freezer, and so, freezer 100 of this embodiment has the advantage of frostless, and makes things convenient for the maintenance of evaporator 33. Specifically, the refrigerator 100 includes a cover plate 4 disposed in the accommodating chamber 10, and the cover plate 4 is connected to the inner container 11 and divides the accommodating chamber 10 into a storage compartment 10a and a refrigerating compartment 10 b. The storage chamber 10a can be used for storing food at low temperature, and the accommodating cavity 10 is opened and closed through the door body 2, so that articles in the storage chamber 10a can be stored and taken; the refrigerating compartment 10b is located between the cover 4 and the inner container 11, and is configured to accommodate the evaporator 33, such that, when the refrigerating system is operated, i.e., when the compressor 31 is started, the refrigerant in the evaporator 33 exchanges heat with the air in the refrigerating compartment 10b to form cold air in the refrigerating compartment 10b, and the cold air can be delivered into the storage compartment 10a through an air delivery duct described later, thereby maintaining a low-temperature environment of the storage compartment 10 a.

Preferably, the evaporator 33 is arranged side by side with the step wall 116 in the left-right direction, for example, in the illustrated embodiment, the step wall 116 is located at the right lower part of the liner 11, and the evaporator 33 is correspondingly located at the left side of the step wall 116, that is, between the step wall 116 and the left side wall 113; of course, in the modified embodiment, if the stepped wall 116 is located at the lower left portion of the inner container 11, the evaporator 33 is correspondingly located at the right side of the stepped wall 116, or if the stepped wall 116 is located at the middle bottom of the inner container 11, the evaporator 33 may be correspondingly located at the right side of the stepped wall 116, or may be correspondingly located at the left side of the stepped wall 116. In this way, by arranging the evaporator 33 and the step wall 116 in the left-right direction, the volume ratio of the refrigerator 100 can be greatly increased compared to the related art.

At least a portion of the refrigerating compartment 10b is arranged side by side with the stepped wall 116 in the left-right direction, correspondingly, depending on the position of the evaporator 33. In the preferred embodiment of the drawings, the refrigerated compartment 10b is disposed immediately adjacent to the stepped wall 116, and accordingly, the refrigerated compartment 10b is formed between the cover plate 4 and the stepped wall 116.

Thus, side cover plate 42 defines the left boundary of refrigeration compartment 10b, step side wall 1162 defines the right boundary of refrigeration compartment 10b, bottom wall 115 defines the lower boundary of refrigeration compartment 10b, and top cover plate 41 defines the upper boundary of refrigeration compartment 10 b. As such, in the preferred embodiment, by disposing the refrigerating compartment 10b next to the stepped wall 116, the volume ratio of the refrigerator 100 can be greatly improved, the storage of the goods is facilitated, and the refrigerating compartment 10b is made adjacent to the compressor compartment 120, so that the piping layout of the refrigerating system is optimized, the refrigerating efficiency is improved, and the flow noise of the refrigerant is reduced. It is to be understood that in an alternative embodiment, the refrigeration compartment 10b may be moved further to the left in the illustrated position away from the step wall 116, such that a portion of the storage compartment 10a may be formed between the refrigeration compartment 10b and the step wall 116.

Further, the front end edge of the cover plate 4 abuts against the front side wall 111 of the inner container 11, and the rear end edge thereof abuts against the rear side wall 112 of the inner container 11, so that the refrigerating compartment 10b is defined by the front side wall 111 and the rear side wall 112, that is, the front side wall 111 defines the front boundary of the refrigerating compartment 10b, and the rear side wall 112 defines the rear boundary of the refrigerating compartment 10b, in addition to the cover plate 4 and the step wall 116. By such arrangement, the volume ratio of the refrigerator 100 is improved, the storage of the stored articles in the storage compartment 10a is facilitated, and the air supply of the refrigerator 100 is improved.

The distance between the front and rear covering edges 141 and 142 in the front-rear direction is smaller than the width of the accommodation chamber 10 in the front-rear direction, that is, the distance between the front and

rear side walls

111 and 112 in the front-rear direction.

In this regard, referring to fig. 5b, the cover plate 4 includes a front cover plate portion 4a and a rear cover plate portion 4b, a front end edge of the front cover plate portion 4a contacts the front side wall 111, a rear end edge of the rear cover plate portion 4b contacts the rear side wall 112, and the front cover plate portion 4a and the rear cover plate portion 4b are provided separately and have a width in the front-rear direction not larger than a distance between the front and

rear edges

141 and 142 in the front-rear direction. So, with apron 4 along the fore-and-aft direction fall into the front cover plate portion 4a and the back cover plate portion 4b that the components of a whole that can function independently set up, when apron 4 is installed or is torn out from holding chamber 10 in holding chamber 10, front cover plate portion 4a and back cover plate portion 4b are loaded and unloaded respectively, can not receive the interference of cabinet mouth 14, thereby make things convenient for the installation and the dismantlement of apron 4, avoid apron 4 fish tail inner bag 11 or cabinet mouth 14, also can accomplish the dismantlement of apron 4 under the condition that need not to dismantle cabinet mouth 14, and then make things convenient for the maintenance of refrigeration compartment 10b internals to change.

Preferably, with reference to fig. 2b and 5b, the rear end edge of the front cover plate portion 4a forms a stepped structure 4a1 recessed towards the refrigeration compartment 10b, in particular, the stepped structure 4a1 at the rear end edge of the top cover plate 41 is recessed downwards for the top cover plate 41, and the stepped structure 4a1 at the rear end edge of the side cover plate 42 is recessed to the right for the side cover plate 42; the front end edge of the rear cover plate portion 4b is pressed against the step structure 4a 1. Thus, the mounting firmness of the cover plate 4 can be enhanced. Of course, in a modified embodiment, the step structure 4a1 may also be formed at the front end edge of the rear cover board portion 4b to press the rear end edge of the front cover board portion 4a against the front end edge of the rear cover board portion 4 b.

In this embodiment, the step structure 4a1 is provided so that the front cover plate 4a and the rear cover plate 4b are smoothly butted, the top cover plate 41 is coplanar with the front cover plate 4a and the rear cover plate 4b, and the side cover plates 42 are coplanar with the front cover plate 4a and the rear cover plate 4 b. In this way, the flatness of the outer surface of the cover plate 4 (i.e., the surface facing the storage compartment 10 a) can be optimized, the aesthetic appearance can be improved, and dirt and grime can be prevented from being trapped due to uneven seams.

Referring to fig. 2a to 5b, the refrigerator 100 further includes a heat-insulating cover plate 43 disposed in the refrigerating compartment 10b, and the heat-insulating cover plate 43 is closely attached to a surface of the cover plate 4 facing the refrigerating compartment 10b to cover the evaporator 33 from above and from the left side, thereby preventing cold air at the evaporator 33 from directly flowing into the storage space 10a via the cover plate 4.

Further, the plurality of air supply ports 5101 are vertically higher than the auxiliary air supply ports 421, and the auxiliary air supply ports 421 are specifically positioned at the bottom of the storage compartment 10a, so that the temperature difference between the upper portion and the lower portion of the storage compartment 10a is reduced.

Preferably, the distance from the auxiliary air blowing port 421 to the front sidewall 111 is shorter than the distance to the rear sidewall 112, so that the auxiliary air blowing port 421 can additionally blow air to the front lower region of the locker room 10a distant from the plurality of air blowing ports 5101. Of course, in a modified embodiment, if the plurality of air blowing ports 5101 are located behind the storage compartment 10a and the air return port 5201 is located in front of the storage compartment 10a, the auxiliary air blowing port 421 is preferably provided at a distance from the front side wall 111 greater than that from the rear side wall 112.

Based on the arrangement of the air outlets 5101 at the upper portion of the storage chamber 10a and the auxiliary air supply 421 at the lower portion of the storage chamber 10a, in an embodiment, the control system can also perform a series of controls on the operation of the refrigerator 100 to realize different air supply modes. That is, the present invention also provides an operation control method of the refrigerator 100.

Specifically, in one embodiment, freezer 100 further includes a temperature sensor disposed in storage compartment 10a and configured to sense a temperature T of storage compartment 10 a. The control system is also connected with the temperature sensor and receives the temperature T from the temperature sensor; meanwhile, the control system is also connected with the refrigerating system to control the starting or closing of the refrigerating system.

In one embodiment, the control system is specifically configured to:

after a starting instruction of the compressor 31 is acquired, the compressor 31 and the fan 60 are controlled to operate, and whether the temperature T reaches a first temperature threshold T1 or not is judged;

the starting instruction is to switch the compressor 31 from the shutdown state to the startup state, as can be known, when the compressor 31 is started and operated, the refrigerant flows along the circulation loop, and the refrigeration system starts to refrigerate, and thus, the obtaining of the starting instruction generally represents that the refrigerator 100 needs to cool the storage compartment 10a, for example, when the temperature T reaches the startup temperature Ton or more, or when the shutdown duration of the compressor 31 reaches the preset time or more, the starting instruction of the compressor 31 is obtained;

the first temperature threshold T1 is higher than the boot temperature Ton;

if it is determined that the temperature T is greater than the first temperature threshold T1, the temperature T is inevitably higher than the start-up temperature Ton, which represents that the inside of the storage compartment 10a is in an abnormally high temperature state when the compressor 31 is started, and at this time, a first air supply path from the fan 60 to the storage compartment 10a through the plurality of air supply ports 5101 is turned on, and a second air supply path from the fan 60 to the storage compartment 10a through the auxiliary air supply port 421 is turned off, that is, cold air at the fan 60 can be blown to the storage compartment 10a through the plurality of air supply ports 5101 but cannot be blown to the storage compartment 10a through the auxiliary air supply port 421, so that a large amount of air is rapidly supplied to the upper portion of the storage compartment 10a without blowing air to the lower portion, and the first air supply path and the second air supply path are simultaneously turned on until the temperature T is reduced to the second temperature threshold T2, that the plurality of air supply ports 5101 and the auxiliary air supply to the storage compartment 10a simultaneously, until the temperature T is reduced to the shutdown temperature Toff;

if it is determined that the temperature T does not reach the first temperature threshold T1, it represents that the air supply temperature in the storage compartment 10a when the compressor 31 is started needs to be lowered but is not in an abnormally high temperature state, and at this time, the first air supply path and the second air supply path are communicated so that the air supply ports 5101 and the auxiliary air supply ports 421 simultaneously supply air to the storage compartment 10 a.

In this way, in the configuration of the control system or the operation control method of the refrigerator 100 in an embodiment, when the compressor 31 is operated, the air supply states of the plurality of air supply ports 5101 and the auxiliary air supply port 421 are controlled according to whether the temperature T of the storage compartment 10a reaches the first temperature threshold T1, so that when the storage compartment 10a is in an abnormally high temperature state, a large amount of air is discharged to the upper part of the storage compartment 10a with a higher temperature through the plurality of air supply ports 5101, the temperature in the storage compartment 10a is rapidly reduced from top to bottom, and the stored articles are prevented from being rotten and deteriorated due to a high temperature state for a long time; when the storage compartment 10a is not in an abnormal high-temperature state but in a normal refrigeration state, air is simultaneously supplied to the upper portion and the lower portion of the storage compartment 10a through the plurality of air supply ports 5101 and the auxiliary air supply ports 421, so that the temperature of the upper portion and the lower portion of the storage compartment 10a is uniform, the cooling rate is increased, and energy is saved and consumption is reduced.

Further, in another embodiment, the control system may be further configured to: after a start instruction of the compressor 31 is obtained, for example, when the temperature T reaches the startup temperature Ton or more, the start instruction is obtained, and the operation of the compressor 31, the operation of the fan 60, the conduction of the first air supply path, and the disconnection of the second air supply path are controlled; during the period, when the door sensor senses the opening state of the door 2 during the operation of the fan 60, the first air supply path and the second air supply path are conducted, so that air is supplied to the upper part and the lower part of the storage compartment 10a through the plurality of air supply openings 5101 and the auxiliary air supply openings 421 in the opened state of the door 2, on one hand, as described above, an air curtain is formed through the plurality of air supply openings 5101 to prevent a large amount of external hot air from entering the storage compartment 10a, and meanwhile, air is supplied through the auxiliary air supply openings 421 to reduce the air volume at the plurality of air supply openings 5101, so that the air pressure born by a human body during taking and placing articles is reduced, and the discomfort of the human body is avoided; furthermore, the wind pressure at the plurality of air supply ports 5101 can be reduced, and airflow noise can be reduced. In addition, in combination with the structural arrangement of the fan 60 (for example, the arrangement of the secondary air outlet 6202 described later), when the door 2 is opened, the multiple air supply outlets 5101 and the auxiliary air supply outlet 421 supply air at the same time, so that the air pressure of the fan 60 can be reduced, and the airflow noise in the fan 60 can be further reduced.

Of course, in a variant embodiment, the control system may also be configured to: after a start instruction of the compressor 31 is obtained, for example, when the temperature T reaches the startup temperature Ton or more, the start instruction is obtained, and the operation of the compressor 31, the operation of the fan 60, the conduction of the first air supply path, and the disconnection of the second air supply path are controlled; during the period, when the door sensor senses the opening state of the door 2 during the operation of the fan 60, the first air supply path is cut off and the second air supply path is conducted, so that air is supplied to the storage compartment 10a through the auxiliary air supply opening 421 instead of the air supply openings 5101, compared with the embodiment in which air is simultaneously supplied to the storage compartment 10a through the air supply openings 5101 and the auxiliary air supply openings 421, the embodiment can obtain a more excellent silencing effect despite that the air curtain effect when the door 2 is opened is cancelled, and can avoid the condition that too much cold air sent out by the air supply openings 5101 flows to the outside from the cabinet opening 14, thereby saving energy and reducing consumption.

Additionally, in one embodiment, the cooler 100 also includes a body sensor. The human body sensor is arranged outside the refrigerator body 1 or outside the door body 2 and used for sensing human body signals in an external preset area of the refrigerator 100. That is, when a human body enters an external preset area of the refrigerator 100, for example, within 0.5m near the front of the refrigerator 100, the human body sensor senses the human body signal.

The human body sensor may be specifically configured as an infrared sensor, an image collector, or other devices known in the art for human body sensing.

The control system may be further connected to the body sensor and receive the body signal from the body sensor. The method can be specifically configured as follows: after a start instruction of the compressor 31 is obtained, for example, when the temperature T reaches the startup temperature Ton or more, the start instruction is obtained, and the operation of the compressor 31, the operation of the fan 60, the conduction of the first air supply path, and the disconnection of the second air supply path are controlled; meanwhile, when the human body sensor senses the human body signal while the blower 60 is in operation, the first air supply path and the second air supply path are turned on, or the first air supply path is cut off and the second air supply path is turned on. Like this, similar to the aforesaid, when the human body is close to door body 2, share or share the air supply volume of a plurality of air supply outlets 5101 through supplementary air supply outlet 421 part, when guaranteeing storing room cooling rate, can reduce the air current noise again, improve the silence effect of freezer.

Further, the fan 60 and the evaporator 33 are arranged side by side in the front-rear direction, specifically, in the present embodiment, the air supply duct 510 and the refrigeration compartment 10b meet at the front side wall 111, and accordingly, the fan 60 is arranged between the evaporator 33 and the front side wall 111, that is, the evaporator 33 is relatively rearward and the fan 60 is relatively forward in the refrigeration compartment 10 b. Of course, in the modified embodiment, if the air duct 510 and the refrigerating compartment 10b meet at the rear side wall 112 (i.e. when the air duct plate 51 is fastened to the rear side wall 112), the fan 60 is modified to be disposed between the evaporator 33 and the rear side wall 112.

In one embodiment of the present invention, the fan 60 is disposed obliquely. In particular, the fan 60 is provided as a centrifugal fan, which comprises an impeller 61 and a volute 62 surrounding the impeller 61, see fig. 2b and 9 a. The volute 62 encloses a guide air cavity 620, and the impeller 61 is arranged in the guide air cavity 620; the impeller 61 rotates about a pivot T which is at an acute angle to the vertical, i.e. the pivot T is neither horizontal nor vertical. So, avoid too big and lead to refrigeration cabin 10b too high because of the span of fan 60 vertical direction, and then promote the volume ratio of freezer 100, also avoid simultaneously because of the too big arrangement space of compression evaporator 33 of the span of fan 60 horizontal direction, and then guarantee great refrigeration rate, can also reduce fan 60's air supply pressure and air current noise in addition.

Preferably, the pivot axis T has an acute angle of 45 to the vertical. With the arrangement, smooth air supply of the fan 60 can be ensured, and air volume loss is reduced.

Further, the pivot T extends perpendicularly to the left-right direction and obliquely from bottom to top toward the evaporator 33, and specifically, in the embodiment of the drawing in which the fan 60 is behind the front evaporator 33, the pivot T extends perpendicularly to the left-right direction and obliquely from the front to the top and back, and of course, in the modified embodiment in which the fan 60 is in front of the rear evaporator 33, the pivot T extends perpendicularly to the left-right direction and obliquely from the top and back to the top and front, and such modified embodiment does not depart from the technical spirit of the present invention.

Referring to fig. 2b and 9a, the volute 62 specifically includes a first end plate 621, a second end plate 622, and a shroud 623. The first end plate 621 and the second end plate 622 are respectively located on both sides of the impeller 61 in the axial direction (i.e., the extending direction of the pivot T), and are arranged substantially opposite to each other; the first end plate 621 is provided with an air inlet 6210; the enclosing plate 623 is located between the first end plate 621 and the second end plate 622, and surrounds the impeller 61 in the radial direction, and is provided with an air outlet 6201, and the volute 62 is buckled on the front surface of the front side wall 111 so that the air outlet 6201 is abutted to the air duct 510. Thus, when the blower 60 is operated, the impeller 61 rotates around the pivot T, and under the driving of the pivot T, air enters the guide air cavity 620 from the air inlet 6201, and finally leaves the guide air cavity 620 through the air outlet 6201 and enters the air duct 510.

As can be seen from the foregoing, the air duct 510 and the refrigerating compartment 10b meet at the front side wall 111 in front of the refrigerating compartment 10b, specifically meet at the passage opening 1112 on the front side wall 111, that is, the passage opening 1112 on the front side wall 111 can be regarded as both the outlet of the refrigerating compartment 10b and the inlet of the air duct 510. Further, referring to fig. 2b, the air outlet 6201 extends obliquely upward away from the pivot T, specifically, obliquely upward and forward away from the pivot T, so that when the fan 60 operates, air enters the air duct 510 through the air outlet 6201 obliquely upward under the driving of the fan, thereby ensuring smooth air supply, small air loss, and avoiding airflow noise.

Further, in combination with the above, the air outlet 6201 is in butt joint with the channel opening 1112 on the front side wall 111 of the inner container 11, the air duct 510 is also in butt joint with the channel opening 1112, and the air duct 510 extends vertically upwards from the channel opening 1112, so that the whole airflow path from the air outlet 6201 to the air duct 510 can be ensured to be smooth and smooth, and air volume loss and noise can be avoided.

Referring to fig. 2b and fig. 9a to 9c, the front end 621a of the first end plate 621 defines an upper boundary of the air outlet 6201, the front end 622a of the second end plate 622 defines a lower boundary of the air outlet 6201, and the front end 621a of the first end plate 621 and the front end 622a of the second end plate 622 are both arranged in a planar plate structure perpendicular to the pivot T. In addition, the shroud 623 includes a first plate portion 623a defining a left boundary of the air outlet 6201 and a third plate portion 623c defining a right boundary of the air outlet 6201, the third plate portion 623c and the first plate portion 623a are each provided in a planar plate structure, and the third plate portion 623c extends parallel to the front-rear direction, and the first plate portion 623a extends from the right rear to the left front. Of course, the illustration is only a preferred embodiment, and the configuration of the third plate portion 623c and the first plate portion 623a, the front end portion 621a of the first end plate 621, and the front end portion 622a of the second end plate 622 is not limited thereto.

In an embodiment, the spiral casing 62 further has an air outlet 6202, that is, the spiral casing 62 has two air outlets, wherein the air outlet 6201 is used as a main air outlet, and the air outlet 6202 is used as a secondary air outlet. That is, when the blower 60 operates, under the driving of the blower, air may enter the air duct 510 through the air outlet 6201 in an obliquely upward direction, and may exit the air guide chamber 620 through the air outlet 6202. Preferably, the shroud 623 comprises a volute tongue 6230 located at the air outlet 6201, the volute tongue 6230 defines a minimum distance from the shroud 623 to the pivot T, which is a minimum radius of the volute 62, that is, the volute tongue 6230 defines a minimum distance from the shroud 623 to an outer edge of the impeller 61 (the outer edge position can be seen by the dashed-dotted line m in fig. 9 c), and the air outlet 6202 opens at the volute tongue 6230. In this way, the air outlet 6202 of the volute 62 is arranged, on one hand, the air outlet 6201 is matched to realize two paths of air outlet of the flow guiding air cavity 620 and realize optimized configuration of air volume, and the air volume is distributed in a manner that the air volume of the air outlet 6201 is greater than that of the air outlet 6202, so that the temperature in each position in the storage chamber 10a is uniform; on the other hand, the position of the air outlet 6202 on the volute 62 reduces the airflow noise of the fan 60.

Preferably, the air outlet 6202 communicates with the auxiliary air outlet 421, that is, in the preferred embodiment, the auxiliary air outlet 421 introduces an air flow from the air guiding cavity 620 through the air outlet 6202, so that noise can be reduced, and air distribution can be optimized. In addition, as can be seen from the foregoing, the air outlet 6201 is connected to the air duct 510 in an upward direction in an oblique manner along the front-back direction, and the air outlet 6202 is disposed toward the side cover plate 1602 along the left-right direction, so that two air supplies perpendicular to each other in the front-back direction and the left-right direction are realized through the arrangement of the air outlet 6201 and the air outlet 6202, an air supply path is optimized, air volume loss is reduced, and flowing noise caused by unsmooth air paths is further reduced.

Preferably, the control system includes a first electrically powered damper and a second electrically powered damper. The first electric air door is movably disposed at the air outlet 6201 to turn on or off the first air path, and it can be understood that when the first electric air door cuts off the first air path, the cold air at the impeller 61 cannot enter the air supply duct 510 through the air outlet 6201; the second electric air door is movably disposed at the air outlet 6202 to turn on or off the second air path, and it can be understood that when the second electric air door cuts off the second air path, the cool air at the impeller 61 cannot leave the air guiding cavity 620 through the air outlet 6202. In this way, the first and second electric dampers are disposed from the volute 62, so that noise caused by wind pressure can be avoided, for example, when the first air path is cut off, the cold air in the guiding air cavity 620 can be prevented from erroneously rushing into the first air path to form a great wind pressure in the first air path, so as to avoid noise or airflow turbulence caused by the wind pressure.

Further, the shroud 623 further includes a second plate portion 623b curvedly disposed around the pivot T, the second plate portion 623 having a first end 623b1 meeting the third plate portion 623c and a second end 623b2 defining a boundary of the air outlet 6202 in the circumferential direction of the pivot T, the second plate portion 623b being gradually away from the pivot T from the first end 623b1 to the second end 623b2 (i.e., the radius gradually increases).

In this embodiment, the air outlet 6202 extends through the tongue 6230. Alternatively, the air outlet 6202 may be opened between the second end 623b2 of the second plate portion 623 and the tongue tip 6230a of the tongue 6230, and a central angle between the air outlet 6202 and the tongue tip 6230a of the tongue 6230 is not greater than 5 °, that is, a first radius line is constructed from a boundary of the air outlet 6202 near the tongue 6230 to the pivot T, and a second radius line is constructed from the tongue tip 6230a of the tongue 6230 to the pivot T, with the pivot T as a center, and the central angle between the two radius lines is the central angle. In addition, the tongue tip 6230a is a position on the volute tongue 6230 where the distance to the pivot T is the smallest.

In this embodiment, the shroud 623 further includes a connecting plate 623d connecting the second end 623b2 of the second plate portion 623b and the volute tongue 6230, and the connecting plate 623d defines an upper boundary of the air outlet 6202, and in a variation, may define a lower boundary of the air outlet 6202, or may define both the upper boundary and the lower boundary of the air outlet 6202. In the circumferential direction of the pivot T, as shown by a projected broken line 623da of the connecting plate 623d in fig. 9c, the connecting plate 623d is provided as a curved plate gradually approaching the pivot T (i.e., gradually decreasing in radius) from the second end 623b2 to the volute tongue 6230. Of course, in a modified embodiment, the connecting plate 623d may be eliminated such that the upper boundary of the outlet opening 6202 is defined by the first end plate 621.

In other words, considering the second plate portion 623b and the connecting plate 623d as a complete curved plate portion in the shroud 623, the curved plate portion extends around the pivot T from the volute tongue 6230 to the third plate portion 623c in the circumferential direction of the pivot T and gradually moves away from the pivot T, and the air outlet 6202 opens in the curved plate portion and is disposed close to the volute tongue 6230.

Further, the first end plate 621 and the second end plate 622 are formed separately, so that the processing and forming of the volute 62 can be facilitated, and the structural assembly of the fan 60 itself can also be facilitated.

The shroud 623 may be integrally formed with either or both of the first end panel 621 and the second end panel 622, that is, the shroud 623 may be integrally formed with the first end panel 621, may be modified to be integrally formed with the second end panel 622, or may have a portion integrally formed with the first end panel 621 and another portion integrally formed with the second end panel 622; of course, shroud 623 is separately formed and assembled to first end panel 621 and second end panel 622. Such variations do not depart from the technical spirit of the utility model.

In the preferred embodiment of the drawings, the enclosing plate 623 is integrally formed with the first end plate 621, so that the assembly efficiency can be improved and the sealing property can be ensured.

Further, the refrigerator 100 includes a fan bracket 63 fixedly assembled with the inner container 11, and the second end plate 622 is integrally formed on the fan bracket 63, so that the impeller 61, the enclosing plate 623 and the first end plate 621 are fixedly supported on the fan bracket 63, which not only facilitates the integral installation of the fan 60, but also reduces the vibration noise when the fan 60 operates.

Preferably, the fan bracket 63 has a shielding plate 631 surrounding the shielding plate 623, and the shielding plate 623 protrudes obliquely upward from the second end plate 622, and the shielding plate 623 is inserted into the inner side (i.e. the side close to the pivot T) of the shielding plate 631, and the outer side surface of the shielding plate 631 is tightly attached to the inner side surface of the shielding plate 631, so that the first end plate 621 and the shielding plate 623 can be fixed, and the sealing performance at the shielding plate 623 can be ensured, thereby preventing the air flow in the guide air cavity 620 from leaking at the joint between the shielding plate 623 and the second end plate 632, improving the air supply efficiency, and reducing the noise.

In one embodiment, the blower bracket 63 is fastened to the inner wall of the inner container 11 by a suspension member 635, and in this embodiment, the blower bracket 63 is fastened to the front sidewall 111 by the suspension member 635. It should be understood that the liner 11 wall tightly assembled with the fan bracket 63 through the hanging member 635 may be alternatively implemented as another liner 11 wall besides the front sidewall 111, for example, in a variant embodiment where the position of the fan 60 is not changed, the fan bracket 63 may be alternatively implemented as tightly assembled with the bottom wall 115 or with the step sidewall 1162 through the hanging member 635, in a variant embodiment where the position of the fan 60 is changed to be between the evaporator 33 and the rear sidewall 112, the fan bracket 63 may be alternatively implemented as tightly assembled with the bottom wall 115 or with the step sidewall 1162 or with the rear sidewall 112 through the hanging member 635, in a variant embodiment where the position of the cooling compartment 10b is changed to be at the lower left portion of the accommodating chamber 10, the fan bracket 63 may be alternatively implemented as tightly assembled with the bottom wall 115 or with the left sidewall 113 or with the rear sidewall 112 or with the front sidewall 111 through the hanging member 635, etc., which are not to be excluded from the technical spirit.

Next, the assembly of the blower holder 63 and the inner wall of the inner container 11 according to the present embodiment will be described in detail with reference to the accompanying examples.

Referring to fig. 9a to 10, the blower bracket 63 includes a retention plate 632, a locking portion 633 formed on the retention plate 632, and a mounting guide groove 634 opened in the retention plate 632.

The retention plate 632 has a first surface 6321 abutting against the inner wall of the inner container 11 and a second surface 6322 disposed opposite to the first surface 6321 along a first direction, where the first direction is perpendicular to the inner wall of the inner container 11 to which the first surface 6321 abuts, and in this embodiment, the first direction 6321 abuts against the front sidewall 111 is a front-back direction and a vector direction from front to back, and of course, if as mentioned above, in a modified embodiment, if the first surface 6321 abuts against the bottom wall 115, the step sidewall 1162/the left sidewall 113, the corresponding first direction is a vertical direction and a left-right direction.

The mounting guide grooves 634 extend along a third direction, the third direction is perpendicular to the first direction, in this embodiment, the third direction is a vertical direction and is a vector direction from bottom to top; the locking portions 633 protrude from the second surface 6322 along the first direction, which is located at two sides of the mounting guide groove 634 in the second direction, i.e., the left and right direction in this embodiment.

The suspension member 635 is fixed to the wall of the inner container 11 and has a suspension post 6351 and a boss 6352. The hanging post 6351 protrudes out of the inner wall of the inner container 11, which is attached by the first surface 6321, along the first direction, i.e. protrudes out of the front sidewall 111 from the front to the back in this embodiment, and the hanging post 6351 fits into the installation guide groove 634 and can move along the installation guide groove 634, i.e. move along the third direction in the installation guide groove 634; the protruding boss 6352 is located at the protruding end of the hanging post 6351 (i.e. the end far away from the liner wall of the liner 11 attached to the first surface 6321, which is the rear end in this embodiment), and protrudes out of the hanging post 6351 in the radial direction. When the fan bracket 63 is installed in the accommodating cavity 10, the hanging column 6351 moves upward in the installation guide groove 634 until reaching the installation position of the fan bracket 63, and at this time, the boss 6352 abuts against the locking portion 633 so that the first surface 6321 of the retention plate 632 tightly abuts against the inner container wall of the inner container 11, so that the fan bracket 63 can be tightly installed on the inner container 11; conversely, when the blower bracket 63 needs to be detached from the wall of the inner container 11, the hanging post 6351 moves downward in the mounting guide groove 634, the boss 6352 disengages from the locking portion 633, and the blower bracket 63 disengages from its mounting position and is finally removed from the inner container 11.

Referring to fig. 9d, the locking portion 633 comprises a guiding inclined surface 6331, and the distance from the guiding inclined surface 6331 to the second surface 6322 gradually increases along the third direction, in this embodiment, the distance from the guiding inclined surface 6331 to the second surface 6322 gradually increases from bottom to top, so that when the blower bracket 63 is installed into the accommodating cavity 10, the boss 6352 vertically moves along the guiding inclined surface 6331, so that the first surface 6321 of the positioning plate 632 is attached to the liner wall of the liner 11 more and more tightly, and is finally locked on the liner 11.

Preferably, the locking portion 633 further comprises a locking surface 6332, the locking surface 6632 is connected to the upper end of the guide slope 6331, which is parallel to the retention plate 632, and the boss 6352 is pressed against the locking surface 6332 at the front end when the blower bracket 63 is installed to its installation position into the accommodation chamber 10.

Further, the width of the mounting guide groove 634 gradually decreases along the third direction, in this embodiment, the width of the mounting guide groove 634 in the left-right direction gradually decreases from bottom to top, so that when the fan support 63 is mounted into the accommodating chamber 10, the hanging post 6351 can easily enter the mounting guide groove 634, and the fan support 53 can be gradually and accurately aligned in the left-right direction along with the movement of the hanging post 6351 along the mounting guide groove 634.

The suspension member 635 of the present embodiment is detachably attached to the liner wall of the inner liner 11. Preferably, referring to fig. 5a, the liner wall of the inner liner 11 is provided with a mounting through hole 1113; in match, referring to fig. 9a and 10, the suspension member 635 includes a first locking clip portion 6353 and a second locking clip portion 6354, and the first locking clip portion 6353 and the second locking clip portion 6354 both protrude out of the suspension post 6351 in the radial direction and are disposed at a distance in the first direction, i.e., the front-rear direction; the suspension member 635 is fixed in the installation through hole 1113, the first locking clamp portion 6353 and the second locking clamp portion 6354 are separated from the inner wall and the outer wall of the inner container 11, and the first locking clamp portion 6353 and the second locking clamp portion 6354 clamp the inner wall of the inner container 11 together, so that the suspension member 635 is fixedly installed on the inner wall of the inner container 11.

Accordingly, referring to fig. 9a, the first clip portion 6353 is configured to match the shape of the indentation 11130. The suspension member 635 has an attachment and detachment position and a lock position: in the attached and detached position and the lock position, the angle of the suspension member 635 around the center axis of the mounting through hole 1113 is different, that is, the suspension member 635 can rotate around the center axis of the mounting through hole 1113 to change between the attached and detached position and the lock position. When the inner container 11 is in the assembled position, the first locking clamp 6353 is aligned with the notch 11130 and can move on the inner side and the outer side of the inner container wall of the inner container 11 through the mounting through hole 1113; in the locked position, the first locking clip portion 6353 is misaligned with the notch 11130 in the circumferential direction of the mounting through hole 1113, and the second locking clip portion 6353 cannot pass through the mounting through hole 1113.

Thus, when the suspension member 635 is mounted on the liner wall of the liner 11, the suspension member 635 is located at the mounting and dismounting position, the first locking clamp 6353 passes through the mounting through hole 1113 until the first locking clamp 6353 and the second locking clamp 6354 are separated from the inner side and the outer side of the liner wall of the liner 11, at this time, the suspension member 635 is rotated to the locking position, so that the first locking clamp 6353 is dislocated from the notch 11130, and the first locking clamp 6353 and the second locking clamp 6354 clamp the liner wall of the liner 11 together.

In this embodiment, the hole wall of the installation through hole 1113 has two notches 11130 oppositely arranged, that is, the two notches 11130 are at two ends of the diameter of the installation through hole 1113; in cooperation therewith, the suspension member 635 has two first locking portions 6353 disposed opposite to each other at both ends of the diameter of the suspension post 6351.

As such, the suspension member 635 may be rotated by an angle not equal to 180 ° around the center axis of the mounting through hole 1113, for example, may be rotated by 90 ° to change between the detached position and the locked position.

Further, the second locking clip portion 6354 and the first locking clip portion 6353 are arranged in sequence along the first direction, that is, the first locking clip portion 6353 is relatively rearward and the second locking clip portion 6354 is relatively forward, and the first locking clip portion 6353 is located between the boss 6352 and the second locking clip portion 6354. Correspondingly, when the suspension member 635 is installed, the suspension member 635 is located at the dismounting position (that is, the first locking part 6353 is aligned with the notch 11130), the boss 6352, the hanging pillar 6352 and the first locking part 6353 move from the outer side of the liner wall of the liner 11 to the inner side of the liner wall of the liner 11 through the installation through hole 1113, then the suspension member 635 rotates by an acute angle, a right angle or an obtuse angle (preferably, a 90 ° right angle), and at this time, the suspension member 635 is located at the locking position, the first locking part 6353 tightly abuts against the inner side surface of the liner wall of the liner 11, and the second locking part 6354 tightly abuts against the outer side surface of the liner wall of the liner 11, so that the installation of the suspension member 635 is realized, and the installation operation is simple and convenient. Of course, in an alternative embodiment, the second locking clip portion 6354 may be located between the protruding portion 6352 and the first locking clip portion 6353, so that the suspension member 635 is installed from the accommodating chamber 10 to the wall of the inner container 11.
