The present invention will be described in detail below with reference to embodiments shown in the drawings. However, the present invention is not limited to the embodiment, and the structural, method, or functional changes made by those skilled in the art according to the embodiment are all included in the scope of the present invention.
Fig. 1 to 11 show an embodiment of a refrigerator according to the present invention, the refrigerator includes a refrigerating compartment, an air supply channel 3 disposed in the refrigerating compartment, and a damper 6 disposed in the air supply channel 3 for supplying air to the refrigerating compartment, wherein the damper 6 includes a door frame 61, an opening 63 located in the middle of the door frame, a first protruding portion 64 and a second protruding portion 65 protruding from positions of the opening 63 adjacent to the door frame 61 and positions spaced from the opening 63 by a certain distance, a damper groove 66 is formed between the first protruding portion 64 and the second protruding portion 65, and an included angle is formed between a lower side and a horizontal plane of the damper 6.
Specifically, as shown in fig. 1 to 3, in the present embodiment, the refrigerator includes a first compartment 1 and a second compartment 2 provided as side-by-side doors, an evaporation chamber 11 provided in the first compartment 1, the first compartment 1 is a freezing compartment, the second compartment 2 is a temperature-variable compartment, and the freezing compartment is provided on the left side of the temperature-variable compartment. Of course, in other embodiments, the second compartment 2 may also be a refrigerating compartment, and the first compartment 1 and the second compartment 2 may also be interchanged. In other embodiments, the refrigerator may also be a conventional top-bottom-opening refrigerator, in which the damper is mainly disposed in the refrigerating air duct to prevent the damper 6 from contacting with the cold air in the evaporation chamber 11 to generate condensation and freeze the damper 6, or a refrigerator having only a single refrigerating chamber.
The evaporation chamber 11 is arranged at the rear side of the first compartment 1, and the refrigerator comprises an evaporator 12 arranged in the evaporation chamber 11 and a freezing fan 13 positioned above the evaporator 12. The width of the evaporator 12 in the transverse direction matches the width of the first compartment 1 in the transverse direction.
As shown in fig. 10, in the present embodiment, the refrigerator further includes an air supply channel 5 disposed at the rear side of the second compartment 2, and a damper 6 disposed in the air supply channel 5 and supplying air in the transverse direction, wherein the damper 6 is disposed close to the evaporation chamber 11 in the transverse direction.
Specifically, in the present embodiment, the first protruding portion 64 protrudes from the periphery of the opening 63, and the second protruding portion 65 protrudes from the periphery of the door frame 61. The protruding length of the first protruding portion 64 is less than the protruding length of the second protruding portion 65, a sealing member may be disposed around the first protruding portion 64 to cooperate with the door 62 to prevent the cool air in the evaporation chamber 11 from entering the second compartment 2, and the second protruding portion 65 may enhance the structural strength of the door frame 61, and also facilitate the installation of the door 62 and the assembly in the air blowing duct 5.
Due to the fact that the humidity of the gas in the second compartment 2 is high, the low temperature in the evaporation chamber 11 is easy to permeate to the side of the second compartment 2 through the air door 6, so that condensation of the gas near the air door 6 is generated, and particularly when the condensation is generated in the air door groove 66, the door 62 and the door frame 61 are easy to freeze and freeze. Therefore, in the embodiment, the lower side of the air door 6 and the horizontal plane form an included angle, so that the condensation in the air door groove 66 can be concentrated to one corner of the lower side, and the icing risk is reduced.
In the present embodiment, in order to discharge the condensation in the damper slot 66, the upper side and the lower side of the damper 6 are also inclined downward from the horizontal direction, specifically, the upper side of the damper 6 is inclined away from the evaporation chamber 11, so that the condensation in the damper slot 66 can flow downward until completely discharging out of the damper slot 66, and the damper 6 is prevented from freezing. Not only simple structure, and manufacturing cost is lower. In other embodiments, a drainage structure may be disposed in the air supply channel 5, or a water receiving pipe may be disposed in cooperation with the corner, so that the condensation is drained out of the air door slot 66, and freezing is avoided.
In the present embodiment, the upper ends of the dampers 6 are inclined rearward and rightward, respectively, in conjunction with fig. 2 and 4. Of course, in other embodiments, the tilt direction of the damper 6 may be adjusted according to the positional relationship between the first compartment 1 and the second compartment 2, the drainage design, and the like.
As shown in fig. 8 and 9, in order to facilitate installation and sealing of the damper 6, the air supply channel 5 includes front air duct foam 51 and rear air duct foam 52 that are mutually matched in front and rear, and middle air duct foam 53 that covers the rear lower portion and the front upper portion of the damper 6, the damper 6 is connected with the front air duct foam 51 and the rear air duct foam 52 through the middle air duct foam 53, during installation, the middle air duct foam 53 is firstly installed at the rear lower portion and the front upper portion of the damper 6, then the damper 6 is installed in the rear air duct foam 52, and the air supply channel 5 can be formed by the air duct foam 51 before assembly.
The front air duct foam 51, the rear air duct foam 52 and the middle air duct foam 53 form an air supply cavity 54 extending in the vertical direction, and the refrigerator further comprises an air duct cover plate 55 arranged on the front side of the front air duct foam 51 and a plurality of air outlets 56 penetrating through the air duct cover plate 55 and the front air duct foam 51 in the front-back direction and arranged at intervals in the vertical direction. The rear air duct foam 52 further has an air guide surface 57 which is located on one side of the air outlet 56 of the air door 6 along the transverse direction and is arranged at an interval with the air door 6, and the air guide surface 57 is obliquely extended from top to bottom to a side far away from the evaporation chamber 11. When the air door 6 is blown out, the air flow can flow downwards along the air guide surface 57, so that the cold air can be uniformly introduced into the second compartment 2 from the air outlet 56.
As shown in fig. 11, in the present embodiment, the air supply passage 5 further includes a rib 58 disposed in the air duct and located near the door opening side of the damper 6, specifically, the rib 58 protrudes forward from the rear duct foam 52, and an upper end of the rib 58 is inclined to a side away from the evaporation chamber 11 and is inclined at an angle substantially equal to an inclination angle of the upper side of the damper 6. Of course, in other embodiments, the rib 58 may be set according to the rotation direction of the door 62 of the damper 6, the inclination direction and the angle of the damper 6.
Specifically, the damper 6 has a closed state when the door 62 is closed, a cooling state when the door 62 is opened, and a steady state in which the opening angle is between the closed state and the cooling state, and when the damper 6 is in the steady state, a gap for air flow circulation is formed between the rib 58 and the door 62.
In this embodiment, the distance from the pivot position of the door 62 and the door frame 61 to the end of the rib 58 is greater than the radius of rotation of the door 62 around the pivot position. Therefore, when the damper 6 is in a steady state, the end of the door body 62 is linearly connected to the rib 58, and the gap is the distance between the end of the door body 62 and the end of the rib 58.
Through setting up protruding rib 58, on the one hand, can adjust air door 6 and be in steady voltage state, at this moment, the air conditioning in the evaporation chamber 11 still can be passed through in the clearance flows into second compartment 2, and the gas in the second compartment 2 passes through return air wind channel 4 and gets into evaporation chamber 11 to make still have the gas circulation of certain degree in the second compartment 2, when having avoided air door 6 to be in the closed condition, the negative pressure that produces when the gas in the second compartment 2 constantly flows into evaporation chamber 11 has reduced the opening power of second compartment 2, improves user's comfort level.
On the other hand, when the door 62 is closed, condensation may occur in a fine gap between the door 62 and the door frame 61, and since the gap is small, the condensation is not easy to flow, the condensation remains in the gap and gradually freezes, and finally the air door groove 66 is easily frozen, so that the air door 6 cannot be normally opened and closed. Therefore, when the damper 6 is in a stable pressure state, the door 62 is angled to increase the distance between the door 62 and the door frame 61, so that even if condensation is generated on the door frame 61, the condensation will flow downward and the damper 6 will not be frozen.
Meanwhile, because the second compartment 2 is the temperature-changing chamber, when the temperature-changing chamber is used as a refrigerating chamber, the air door 6 can be always kept in a stable pressure state, and the second compartment 2 is continuously cooled through the gap between the door body 62 and the convex rib 58 so as to achieve the aim of refrigerating, so that the opening and closing of the air door 6 are not required to be repeatedly adjusted, the opening and closing times of the air door 6 are reduced, and the fault rate of the air door 6 is further reduced.
In order to ensure that the door 62 and the door frame 61 have a certain angle when the damper 6 is in the steady voltage state, so that the gap between the door 62 and the door frame 61 is large enough, and the condensation can not stay in the gap, in the embodiment, the door opening angle of the door 62 in the steady voltage state is 25-35 degrees, preferably 30 degrees, and the distance between the rib 58 and the door frame 61 is 25-35 mm.
In order to ensure that the cool air can smoothly flow through the gap between the door 62 and the rib 58 and no condensation remains in the gap, the end of the rib 58 is disposed in a circular arc shape, and the gap between the door 62 and the rib 58 is in the range of 3-7mm, preferably 5 mm.
Of course, in other embodiments, the distance from the pivot position of the door 62 and the door frame 61 to the end of the rib 58 may also be smaller than the rotation radius of the door 62 around the pivot position. That is, when the door 62 is opened, the rib 58 prevents the door 62 from being completely opened, and at this time, the door 62 can be opened to a stable pressure state, so that a certain gap is formed between the door 62 and the rib 58. And the door 62 opening angle when the air door 6 is in the refrigeration state is located between the closed state and the steady voltage state, in order to ensure that the cold air in the evaporation chamber 11 can effectively enter the second chamber 2 through the air door 6 in the refrigeration state, the air duct foam of the air supply channel 5 can be redesigned so as to provide enough air output.
As shown in fig. 1 to 3, in this embodiment, the refrigerator further includes a supply air duct 3 and a return air duct 4 which are respectively located at the upper and lower sides and are communicated with the evaporation chamber 11 and the second chamber 2 along the transverse direction, the return air duct 4 includes a return air outlet 41 communicated with the evaporation chamber 11 and a return air inlet 42 communicated with the second chamber 2, and the return air duct 4 is gradually narrowed from the return air inlet 42 toward the return air outlet 41.
Air supply duct 3 set up in the top of 2 between first room 1 and second and lie in along the transverse direction freezing fan 13 one side, so, can be convenient for freezing fan 13 blows the air conditioning in 11 evaporation chambers to air supply duct 3 fast. In the present embodiment, the air supply duct 3 is a heat insulating member made of a heat insulating material, generally made of foam, and the air supply duct 3 has an air supply inlet 31 communicating with the evaporation chamber 11 and an air supply outlet 32 communicating with the second compartment 2.
Air supply duct 3 has inner wall 33 and inner wall 34 under the air supply on the air supply, inner wall 33 and air supply down inner wall 34 all are the tilt up extension setting to second compartment 2 from evaporation cavity 11, promptly inner wall 33 and air supply down inner wall 34 all are the tilt up extension setting to air supply export 32 side from air supply import 31. In the present embodiment, the upper blowing inner wall 33 and the lower blowing inner wall 34 are both disposed to extend obliquely upward from left to right, but in other embodiments, for example, when the first compartment 1 is located on the right side of the second compartment 2, the upper blowing inner wall 33 and the lower blowing inner wall 34 are both disposed to extend obliquely upward from right to left.
The purpose is that the humid air in the second compartment 2 is likely to enter the air supply duct 3, when the humid air contacts the low temperature in the evaporation chamber 11, condensation is easily generated, and the condensation can respectively flow into the evaporation chamber 11 along the upper air supply inner wall 33 and the lower air supply inner wall 34, so that the air supply duct 3 is prevented from being frozen and blocking the air supply duct 3.
As shown in fig. 4 and 5, in the present embodiment, the return air duct 4 is gradually narrowed from right to left. When the first compartment 1 is located at the right side of the second compartment 2, the return air duct 4 is gradually narrowed from left to right. Therefore, when the airflow in the second compartment 2 flows from the return air inlet 42 to the return air outlet 41, the flow rate is gradually increased, so that the flow rate on the side of the return air outlet 41 is larger, the return air flow can move a longer distance in the transverse direction, the contact area of the return air flow and the evaporator 12 is increased, and the risk that the evaporator 12 is excessively frosted close to the side of the return air outlet 41 to block the return air outlet 41 is reduced.
To further reduce the excessive frost formation on the return air outlet 41 side, in this embodiment, the lower end of the evaporator 12 is not lower than the upper end of the return air outlet 41, but in other embodiments, the evaporator 12 may be disposed away from the return air outlet 41 in the transverse direction when the width of the evaporator 12 in the transverse direction is relatively small.
In the present embodiment, the return air duct 4 has an upper return air inner wall 43 and a lower return air inner wall 44, and the upper return air inner wall 43 and the lower return air inner wall 44 extend obliquely downward from the return air inlet 42 toward the return air inlet 42. On one hand, condensation generated in the return air duct 4 can flow into the evaporation chamber 11 along the upper return air inner wall 43 and the lower return air inner wall 44, and is finally collected by a water receiving device in the evaporation chamber 11, and on the other hand, the return air flow is integrally inclined downwards, so that the contact area between the return air flow and the evaporator 12 close to the return air outlet 41 side is further reduced, and the frosting risk at the position is reduced.
And the inclination angle of the return air upper inner wall 43 is greater than that of the return air lower inner wall 44, so that the size of the return air outlet 41 can be further reduced, the air flow rate at the return air outlet 41 can be increased, further, the air can move a longer distance to contact more areas on the evaporator 12, and the risk that the evaporator 12 is too much frosted near the return air outlet 41 side to block the return air outlet 41 is reduced. While also reducing the amount of cooling air in the evaporation chamber 11 that flows back into the second compartment 2.
In this embodiment, the second compartment 2 further has a return air area provided in cooperation with the return air inlet 42, and the return air area has a plurality of air holes 21 extending therethrough in the lateral direction. Thereby reducing the amount of cooling air in the evaporation chamber 11 that flows back into the second compartment 2. Thereby reducing temperature fluctuations within second compartment 2.
In order to avoid the cold air in the evaporation chamber 11 through the return air duct 4 flows back to in the second compartment 2, cause the temperature fluctuation in the second compartment 2, the refrigerator still include with return air duct 4 cooperation sets up in order to block the separation device that evaporation chamber 11 and 2 air currents of second compartment flow. In this embodiment, the blocking means is a one-way valve that only allows the air flow from the second compartment 2 to the evaporation chamber 11, i.e. the cold air in the evaporation chamber 11 cannot enter the second compartment 2. Not only simple structure, the cost is lower, and does not influence normal gas circulation. Of course, in other embodiments, the blocking device may be an electrically operated damper.
As shown in fig. 3, in the present embodiment, the refrigerator further includes a third compartment (not shown) disposed above the first compartment 1 and the second compartment 2, and a return air channel communicating the third compartment with the evaporation chamber 11, the third compartment is a refrigerating compartment, the return air channel has a slot 14 disposed in the evaporation chamber 11 and located below the evaporator 12, and a center line of the slot 14 in the transverse direction is located on a side of the center line of the evaporator 12 in the transverse direction away from the second compartment 2.
The slot 14 is disposed below the evaporator 12, so that on one hand, the refrigerating fan 13 can prevent the return air flow of the third compartment from being directly blown into the second compartment 2, which affects the storage effect of the second compartment 2. On the other hand, the slots 14 are located further away from the second compartment 2, and the return air of the third compartment can be made to contact as much as possible of the evaporator 12 on the side away from the second compartment 2, thereby reducing the frost formation area of the evaporator 12 near the return air outlet 41.
