In a variation, the condenser 32 may also be disposed in the pressing chamber 120 to dissipate heat together with the compressor 31, and the heat dissipation manner may be any manner that is feasible and is not described herein.

Further, the inner container 11 is configured as a box-type structure with an open upper portion as described above, and the container wall includes a side wall 111, a side wall 112, a side wall 113, a side wall 114, a bottom wall 115, and a step wall 116, as shown in fig. 2a, 2b, and 4.

In the present embodiment, the bottom wall 115 is a substantially horizontally disposed flat plate; the side wall 111, the side wall 112, the side wall 113 and the side wall 114 are all positioned above the bottom wall 115 and extend substantially vertically; the side wall 111 and the side wall 112 are oppositely arranged along a first direction, and the side wall 113 and the side wall 114 are oppositely arranged along a second direction; as mentioned above, the first direction is a front-back direction, and the second direction is a left-right direction, so that the sidewall 111 can be also referred to as a front sidewall 111, the sidewall 112 can be also referred to as a back sidewall 112, the sidewall 113 can be also referred to as a left sidewall 113, and the sidewall 114 can be also referred to as a right sidewall 114.

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 press chamber 120, and it can be seen that the stepped wall 116 is basically arranged to avoid the press chamber 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 if the position of the press machine room 120 is changed from the lower right portion of the cabinet 1 shown in the drawings to other positions, such as the lower left portion, the middle portion, the lower rear portion, and the like of the cabinet 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, the stepped wall 116 includes a stepped top wall 1161 and a stepped side wall 1162. The lower end edge of the stepped 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; the stepped top wall 1161 defines the top of the stepped wall 116, which is substantially perpendicular to the stepped side wall 1162, i.e., parallel to the bottom wall 115, and the stepped top wall 1161 extends rightward from the upper edge of the stepped side wall 1162 until it is vertically connected to the lower edge of the right side wall 114 of the 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 at an obtuse angle or an acute angle, and step wall 116 may also be a completely curved plate without any distinct 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 10b. 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 used for accommodating the evaporator 33, so 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 passage described later, thereby maintaining the low-temperature environment of the storage compartment 10a.

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 lower right portion of the inner container 11, and the evaporator 33 is correspondingly located at the left side of the step wall 116, i.e., 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 part of the refrigerating compartment 10b is arranged side by side with the stepped wall 116 in the left-right direction, correspondingly, in accordance with 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.

Specifically, referring to fig. 5a, the cover plate 4 includes a side cover plate 42 extending vertically upward perpendicular to the bottom wall 115 and a top cover plate 41 extending horizontally rightward from an upper end edge of the side cover plate 42, the side cover plate 42 and the top cover plate 41 are substantially perpendicular, and a right end edge of the top cover plate 41 is connected to the stepped wall 116 and is substantially flush with the stepped top wall 1161. Thus, side cover plate 42 defines the left boundary of refrigeration compartment 10b, stepped 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 10b. As such, in the preferred embodiment, by disposing the refrigerating compartment 10b in close proximity to the stepped wall 116, the volume ratio of the refrigerator 100 can be greatly increased, the storage of goods is facilitated, and the refrigerating compartment 10b is made to be 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 refrigerating compartment 10b may be moved further to the left in the illustrated position away from the stepped wall 116, so that a portion of the storage compartment 10a may be formed between the refrigerating compartment 10b and the stepped 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 the arrangement, the volume ratio of the refrigerator 100 is improved, storage objects can be placed in the storage chamber 10a conveniently, and air supply of the refrigerator 100 can be improved more favorably.

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 separately provided and both have widths in the front-rear direction not greater than a distance between the front hem 141 and the rear hem 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 pulled out from holding chamber 10 in holding chamber 10, front cover plate portion 4a and back cover plate portion 4b load and unload 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 need not to dismantle the dismantlement of accomplishing apron 4 under the condition of cabinet mouth 14, and then make things convenient for the maintenance of refrigeration compartment 10b internal component to change.

Preferably, referring to fig. 2b and 5b, the rear end edge of the front cover plate portion 4a forms a stepped structure 4a1 recessed toward the refrigerating compartment 10b, specifically, the stepped structure 4a1 at the rear end edge of the top cover plate 41 is recessed downward for the top cover plate 41, and the stepped structure 4a1 at the rear end edge of the side cover plate 42 is recessed rightward for the side cover plate 42; the front end edge of the rear cover plate portion 4b is pressed against the stepped 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 plate portion 4b while pressing the rear end edge of the front cover plate portion 4a against the front end edge of the rear cover plate portion 4 b.

In this embodiment, the step structure 4a1 may be provided such that the front cover plate 4a and the rear cover plate 4b are smoothly abutted, 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 appearance can be improved, and dirt collection due to uneven seams can be avoided.

Referring to fig. 2a to 5b, the refrigerator 100 further includes a heat-insulating cover plate 43 disposed in the refrigerating compartment 10b, the heat-insulating cover plate 43 being 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 passing through the cover plate 4 into the storage space 10a. Preferably, the seam between the front cover part 4a and the rear cover part 4b is attached inside the surface of the thermal cover 43, i.e. the thermal cover 43 extends from the surface of the front cover part 4a to the surface of the rear cover part 4b without any break, so that the seam between the front cover part 4a and the rear cover part 4b is shielded by the thermal cover 43, thereby preventing the cold air at the evaporator 33 from flowing to the storage space 10a through the seam between the front cover part 4a and the rear cover part 4 b.

The decoration cover 470 has a catch 470, and a groove circumferential wall 462 of the mounting groove 460 is opened with a bayonet 4601, and the catch 470 is caught in the bayonet 4601 to restrict the decoration cover 470 from being separated from the cover plate 4. Through the cooperation of pawl 470 and bayonet 4601, the quick assembly of decorative cover 470 can be achieved.

Further, as described above, the refrigerator 100 of the present embodiment is implemented as an air-cooled refrigerator including an air duct for communicating the storage compartment 10a and the refrigerating compartment 10b, and an air supply fan 60 for driving air to flow (see fig. 2 b).

Preferably, referring to fig. 2a and 2b, the duct includes an air supply duct 510, an air return duct 520, a plurality of air supply ports 5101, and an air return port 5201. Wherein, the air supply duct 510 is used for introducing air from the refrigerating compartment 10b, that is, air flows from the refrigerating compartment 10b to the air supply duct 510; a plurality of air supply ports 5101, which communicate the air supply duct 510 with the storage compartment 10a, are exposed in the storage compartment 10 a; the return duct 520 returns air to the refrigerating compartment 10b, that is, air flows from the return duct 520 to the refrigerating compartment 10b; the air return opening 5201 is exposed in the storage compartment 10a, and communicates the storage compartment 10a with the air return duct 520. When the refrigeration system operates, under the driving of the fan 60 (at this time, the fan 60 operates), cold air in the refrigeration compartment 10b enters the air supply duct 510 until entering the storage compartment 10a through the air supply opening 5101, then air in the storage compartment 10a enters the air return duct 520 through the air return opening 5201, and finally returns to the refrigeration compartment 10b through the air return duct 520; the cooling of the storage compartment 10a is realized by the circulation.

In the present embodiment, the width of the console room 10a in the front-rear direction is much smaller than the width in the left-right direction, the air blowing port 5101 is disposed at the front upper portion of the console room 10a, and the air return port 5201 is disposed at the rear of the console room 10a. Thus, when the refrigeration system is operated, air in the air supply duct 510 enters the front upper portion of the storage compartment 10a through the air supply opening 5101 under the driving of the fan 60 as indicated by the arrow in fig. 2b, and then cool air flows backward toward the rear of the storage compartment 10a at the front upper portion of the storage compartment 10a until it enters the return duct 520 from the return opening 5201. Thus, in the embodiment, by arranging the air supply at the upper front part of the storage compartment 10a and the air return at the rear part, on one hand, the cooling efficiency in the storage compartment 10a can be enhanced, and the cold flow unsmooth caused by too far distance between the air supply opening 5101 and the air return opening 5201 is avoided, so that the temperature difference at each part in the storage compartment 10a can be reduced; on the other hand, when the front end of the door body 2 pivots upward to open the storage compartment 10a, the air blown out from the air supply opening 5101 flows from the front of the storage compartment 10a to the rear, so that a front-to-rear air curtain is formed at an upper opening of the storage compartment 10a, thereby preventing a large amount of hot air in the external environment from entering the storage compartment 10a to cause severe temperature fluctuation of the storage compartment 10a, and the air curtain is not blown to a user in front of the refrigerator 100 to prevent discomfort of the user; meanwhile, when the cold air of the air curtain blows to the rear part of the refrigerator 100, the cold air is blocked by the door body 2 and enters the storage compartment 10a, so that the cold energy loss is avoided, and the energy consumption of the refrigerator 100 is reduced.

In this way, the cooperation between the air duct plate 51 and the stopper rib 143 not only enables further fixation of the air duct plate 51, but also enables optimization of the air blowing effect by blowing air through the plurality of air blowing ports 5101 of the air duct plate 51.

In one embodiment, referring to fig. 4, the side cover 42 is provided with an auxiliary air supply opening 421, the auxiliary air supply opening 421 is exposed in the storage compartment 10a, and the refrigeration compartment 10b is communicated with the storage compartment 10a through the auxiliary air supply opening 421, so that under the driving of the fan 60 (when the fan 60 is operated), cold air in the refrigeration compartment 10b can enter the storage compartment 10a through the auxiliary air supply opening 421, and the temperature of the storage compartment 10a is reduced. Thus, by combining the arrangement of the air supply ports 5101, the storage compartment 10a can supply air through the air supply ports 5101 at the front part and can supply air through the auxiliary air supply ports 421 at the side parts, so that bidirectional air supply is realized, and the temperature uniformity of the storage compartment 10a is favorably realized; furthermore, air is directly supplied to the side cover plate 42, and the air supply duct plate 51 is provided, so that the air supply pressure of the air supply duct 510 can be relieved, the structure of the air supply duct plate 51 can be simplified, and the overall structural layout of the refrigerator 100 can be optimized.

Further, the air supply ports 5101 are vertically higher than the auxiliary air supply port 421, and the auxiliary air supply port 421 is specifically located 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. However, 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 compartment 10a and the auxiliary air supply 421 at the lower portion of the storage compartment 10a, in an embodiment, the control system can 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 10a. 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 value T1 or more is judged;

as can be known from the foregoing, 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 start instruction generally represents that the refrigerator 100 needs to cool the storage compartment 10a, for example, when the temperature T reaches the start temperature Ton or the stop duration of the compressor 31 reaches the preset time, the start instruction of the compressor 31 is obtained;

the first temperature threshold value T1 is higher than the starting temperature Ton;

if the temperature T is judged to be higher than the first temperature threshold T1, the temperature T is inevitably higher than the startup 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, 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 conducted, and a second air supply path from the fan 60 to the storage compartment 10a through the auxiliary air supply port 421 is cut 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 and cannot be blown to the storage compartment 10a through the auxiliary air supply port 421, so that a large amount of air can be quickly supplied to the upper part of the storage compartment 10a without supplying air to the lower part, and the first air supply path and the second air supply path are conducted simultaneously 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 path 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 inside of the storage compartment 10a when the compressor 31 is started needs to be cooled by air supply 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 10a.

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 operates, the air supply states of the 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 air supply ports 5101, and thus the temperature in the storage compartment 10a is quickly lowered from top to bottom, and stored articles are prevented from being rotted and deteriorated due to a high temperature state for a long time; when the storage compartment 10a is not in an abnormally high temperature state but in a conventional 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 acquired, for example, when the temperature T reaches the startup temperature Ton or more, the start instruction is acquired, 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 self-structure setting of the fan 60 (for example, the setting of the secondary air outlet 6202 described later), when the door body 2 is opened, the air inlets 5101 and the auxiliary air outlets 421 supply air simultaneously, 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 open 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 port 421 instead of the air supply ports 5101, and compared with the embodiment in which air is simultaneously supplied to the storage compartment 10a through the air supply ports 5101 and the auxiliary air supply ports 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 also avoid the occurrence of the situation that excessive cold air supplied by the air supply ports 5101 flows to the outside from the cabinet port 14, so that energy is saved and consumption is reduced.

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 is 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 that can be used for human body sensing.

The control system may be further connected to the human body sensor and receive the human body signal from the human body sensor. The specific configuration can be 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 during the operation of the blower 60, the first air supply path and the second air supply path are conducted, or the first air supply path is cut off and the second air supply path is conducted. Like the above, when the human body approaches the door 2, the auxiliary air supply port 421 partially or completely distributes the air supply amount of the air supply ports 5101, so that the cooling rate of the storage compartment is ensured, the airflow noise is reduced, and the silencing effect of the refrigerator is improved.

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 refrigerating 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 backward and the fan 60 is relatively forward in the refrigerating compartment 10b. Of course, in the modified embodiment, if the air duct 510 and the refrigerating compartment 10b meet at the rear sidewall 112 (i.e. when the air duct plate 51 is fastened to the rear sidewall 112), the fan 60 is modified to be disposed between the evaporator 33 and the rear sidewall 112.

In one embodiment of the present invention, the fan 60 is arranged 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 leading to the refrigeration compartment 10b too high because of the too big span of fan 60 vertical direction, and then promote freezer 100's percentage of capacity, also avoid simultaneously because of the too big arrangement space of compression evaporimeter 33 of fan 60 horizontal direction's span, and then guarantee great refrigeration rate, can also reduce fan 60's air supply pressure and air current noise in addition.

Preferably, the pivot T has an acute angle of 45 DEG or more with the vertical direction. 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 particularly 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 front to bottom and back to top, but 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 back to bottom and front to top, 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 encloses the impeller 61 in the radial direction, and it has an air outlet 6201, and the volute 62 is fastened on the front surface of the front sidewall 111 to make the air outlet 6201 abut against the air duct 510. Thus, when the fan 60 operates, the impeller 61 rotates around the pivot T, and under the driving of the impeller, air enters the diversion air cavity 620 from the air inlet 6201, and finally leaves the diversion air cavity 620 through the air outlet 6201 and enters the air duct 510.

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

Further, in combination with the above, the air outlet 6201 is abutted to the channel opening 1112 on the front side wall 111 of the inner container 11, and the air duct 510 is also abutted to the channel opening 1112, and the air duct 510 extends vertically upward 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 plane plate structure perpendicular to the pivot T. In addition, the enclosing plate 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 in parallel to the front-rear direction, and the first plate portion 623a extends from the right rear direction to the left front direction. Of course, the illustration is merely a preferred embodiment, and the configurations 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 are not limited thereto.

In one 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 primary air outlet, and the air outlet 6202 is used as a secondary air outlet. That is, when the fan 60 operates, under the driving of the fan, air may enter the air duct 510 obliquely upward through the air outlet 6201, 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, in the arrangement of the air outlet 6202 of the volute 62, on one hand, the air outlet 6201 is matched to realize two paths of air outlet of the diversion air cavity 620, and the optimal configuration of the air volume is realized, 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 uniform temperature of each part in the storage compartment 10a is favorably realized; 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 is communicated to the auxiliary air outlet 421, that is, in the preferred embodiment, the auxiliary air outlet 421 introduces air flow from the diversion air cavity 620 through the air outlet 6202, so that noise can be reduced, and air volume distribution can be optimized. In addition, as can be seen from the above description, 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 ducts 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 duct 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 connect or cut off the second air path, and it can be understood that when the second electric air door cuts off the second air path, the cold 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 very large wind pressure in the first air path, so as to avoid noise or turbulent airflow caused by the wind pressure.

Further, the shroud 623 further includes a second plate portion 623b curvedly arranged 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 outlet 6202 in the circumferential direction of the pivot T, the second plate portion 623b being gradually distant from the pivot T from the first end 623b1 to the second end 623b2 (i.e., the radius is gradually increased).

In this embodiment, the 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 volute tongue 6230, and a central angle between the air outlet 6202 and the tongue tip 6230a of the volute 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 volute tongue 6230 to the pivot T, and a second radius line is constructed from the tongue tip 6230a of the volute 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. The tongue tip 6230a is a position on the volute tongue 6230 where the distance to the pivot axis 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 of the air outlet 6202 and the lower boundary of the air outlet 6202. In the circumferential direction of the pivot T, as shown by a projected dotted 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 complete curved plate portions in the enclosing plate 623, the curved plate portions extend around the pivot T from the tongue 6230 to the third plate portion 623c in the circumferential direction of the pivot T and gradually get away from the pivot T, and the air outlet 6202 opens in the curved plate portions and is disposed near the 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 can 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 invention.

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 performance can be ensured.

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

Preferably, the fan bracket 63 has a protection plate 631 covering the enclosure 623, and the enclosure 623 is inserted into the protection plate 631 (i.e. the side close to the pivot T) and has an outer surface closely attached to the inner surface of the protection plate 631, so that the first end plate 621 and the enclosure 623 can be fixed, the sealing performance at the enclosure 623 can be ensured, the air flow in the guide air cavity 620 can be prevented from leaking at the joint between the enclosure 623 and the second end plate 632, the air supply efficiency is improved, and the noise is reduced.

In one embodiment, the blower bracket 63 is fastened to the inner wall of the inner container 11 by the suspension member 635, and in this embodiment, the blower bracket 63 is fastened to the front sidewall 111 by the suspension member 635. It is understood that the liner 11 liner wall tightly assembled with the fan bracket 63 through the hanging member 635 may be alternatively implemented as another liner 11 liner wall besides the front sidewall 111, for example, in a variation embodiment where the position of the fan 60 is unchanged, 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 variation embodiment where the position of the fan 60 is changed 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 variation embodiment where the position of the cooling chamber 10b is changed to 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, and the like, and these variations do not depart from the present technical spirit and are not enumerated one by one.

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

The mounting guide groove 634 extends along a third direction, the third direction is perpendicular to the first direction, in this embodiment, the third direction is a vertical direction and 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-right direction in this embodiment.

The suspension member 635 is fixed on the wall of the liner 11 and has a suspension post 6351 and a boss 6352. The hanging post 6351 protrudes out of the inner container wall of the inner container 11, which is attached by the first surface 6321, in this embodiment, the front side wall 111 protrudes from the front to the back, and the hanging post 6351 fits in the installation guide groove 634 and can move along the installation guide groove 634, that is, can move in the installation guide groove 634 along the third direction; the protrusion 6352 is located at the protruding end of the hanging post 6351 (i.e. the end of the inner container 11 far from the wall where the first surface 6321 is attached, in this embodiment, the rear end), and protrudes radially beyond the hanging post 6351. When the blower bracket 63 is installed in the accommodating cavity 10, the hanging column 6351 moves upwards in the installation guide groove 634 until reaching the installation position of the blower 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 liner wall of the liner 11, so that the blower bracket 63 can be tightly installed on the liner 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 wall of the inner bag 11. Preferably, referring to fig. 5a, the liner wall of the 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, 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 an interval 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 part 6353 and the second locking clamp part 6354 are separated from the inner wall and the outer wall of the liner 11, and the first locking clamp part 6353 and the second locking clamp part 6354 clamp the liner wall of the liner 11 together, so that the suspension member 635 is fixedly installed on the liner wall of the liner 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 central axis of the mounting through hole 1113 is different, that is, the suspension member 635 can rotate around the central 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 detachable position, the first locking part 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 6353 is misaligned with the notch 11130 in the circumferential direction of the mounting through hole 1113, and the second locking clip 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 a matching manner, 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.
