Example 1

The invention relates to a refrigerator, as shown in fig. 1, 5 and 18, which comprises a refrigerator 100, wherein a storage chamber of the refrigerator 100 is internally provided with a drawer for storing articles; wherein,,

a relief opening 311 is arranged on the outer wall of one drawer, and the relief opening 311 is communicated with at least one air outlet of the air duct component of the refrigerator to form a temperature changing drawer 301;

the other drawer outer wall and the air duct assembly outer wall and the refrigerator inner wall jointly clamp to form an air return area of an air return opening 51 of the refrigerator;

independent air-out action is realized through the two air outlets of the air duct assembly, so that different temperature adjustment inside and outside the temperature changing drawer 301 in the refrigerator is formed.

In this embodiment, by providing temperature change drawer 301 in refrigerator 100, temperature change drawer 301 has a sealed or relatively sealed storage cavity, and by changing the air intake in temperature change drawer 301, the temperature in temperature change drawer 301 is adjusted, so as to meet the storage temperature requirements of different articles, and prolong the storage life.

By providing relief opening 311 in temperature change drawer 301, cool air in the air duct assembly is facilitated to be effectively transferred into temperature change drawer 301, thereby improving the air intake effect of temperature change drawer 301. Return air inlet 51 is positioned on the back of the other drawer and through the barrier action of the drawer, the return air resistance of the outside of temperature change drawer 301 is increased, and the overflow rate of the air in temperature change drawer 301 is slowed down.

It should be understood that the number of drawers provided in the refrigerator 100 in the above embodiment is two, but only the technical solution is described for convenience. In other embodiments, the refrigerator 100 may be provided with three, four or even more drawers to enrich the sorting refrigeration function.

In one embodiment, temperature change drawer 301 is disposed below a shelf of a refrigerator; the outer wall of air duct assembly 20 forms an isolation structure with temperature change drawer 301 and the shelves of the refrigerator to block the flow of air in temperature change drawer 301 to the return air area. Specifically, the air return speed of the surrounding air of the temperature changing drawer 301 is delayed by the blocking of the shelf and the drawer opposite to the air return opening 51, and the temperature keeping and controlling effects on the outer wall of the temperature changing drawer 301 are achieved.

In one embodiment, temperature change drawer 301 is positioned near the bottom wall of the refrigerator cabinet to shorten its distance from the refrigeration device in the refrigerator and increase the temperature change speed.

In one embodiment, a drawer is provided with a moisturizing structure to regulate the humidity environment within the drawer to form a moisturizing drawer 302. Specifically, the moisturizing drawer 302 is provided with the moisturizing structure 303, and the air flow inside and outside the moisturizing drawer 302 is exchanged after passing through the moisturizing structure 303, and the exchange speed of the air flow inside and outside the moisturizing drawer 302 is adjusted through the moisturizing structure 303, so that the moisturizing effect is achieved, a humidity environment suitable for storing articles is provided, and the storage life is prolonged. By arranging the temperature changing drawer 301 and the moisture preserving drawer 302, the classified preservation functions of the refrigerator 100 are enriched, and diversified preservation environments are provided.

Further, the back of the moisturizing drawer 302 corresponds to the position of the air return opening 51, and the moisturizing drawer 302, the outer wall of the air duct assembly and the inner wall of the refrigerator jointly clamp to form an air return area of the air return opening 51 of the refrigerator.

In one embodiment, at least one side of temperature change drawer 301 is configured with a drawer to slow down the air flow rate around temperature change drawer 301. Specifically, the air duct assembly 20 includes two air outlets, the second air outlet 215 is a main air outlet, and is located at the upper portion of the refrigerator liner, so as to form a top-down refrigeration air flow; the first air outlet 211 is configured to independently supply air to the temperature change drawer 301. The downward wind force of the second air outlet 215 slows down the upward overflow speed of the air in the temperature changing drawer 301, and by arranging another drawer and the temperature changing drawer 301 side by side, the left and right overflow speed of the temperature changing drawer 301 is further limited, so that the air overflow speed of the temperature changing drawer 301 can be slowed down, and the internal heat preservation of the temperature changing drawer is facilitated. Further, temperature change drawer 301 is positioned adjacent to the bottom wall of the refrigerator cabinet to slow down the downward overflow of air from inside temperature change drawer 301. Further, the back of the other drawer, which is arranged to the left and right of temperature change drawer 301, corresponds to the position of return air inlet 51 to further slow down the gas overflow speed of temperature change drawer 301. It should be appreciated that the duct assembly 20 further includes a third air outlet, a fourth air outlet, or even more to enhance the air outlet effect.

In yet another embodiment, temperature change drawer 301 is positioned with another drawer in sequence along the height of the refrigerator, with both drawers being positioned in the same vertical orientation, suitable for use in a single door refrigerated compartment. Further, the back of the other drawer, which is arranged to the left and right of temperature change drawer 301, corresponds to the position of return air inlet 51 to further slow down the gas overflow speed of temperature change drawer 301. In one embodiment, a fixed frame 90 is provided in the refrigerator 100, and a temperature changing drawer 301 and another drawer are respectively slidably provided in two frame regions of the fixed frame 90 for assembly.

In one embodiment, as shown in fig. 5, both sides of the fixing frame 90 are slidably connected to both inner surfaces of the refrigerator cabinet 50. Specifically, taking a drawer assembled together with the temperature changing drawer 301 in the fixing frame 90 as the moisturizing drawer 302 as an example, the fixing frame 90 is drawn relative to the refrigerator liner 50, so as to drive the temperature changing drawer 301 and the moisturizing drawer 302 to perform a drawing motion together. The fixing frame 90, the temperature changing drawer 301 and the moisture keeping drawer 302 are assembled and then are put into the refrigerator container 50.

Further, the fixing frame 90 has a frame structure, and two accommodating cavities 93 are provided for slidably arranging a temperature changing drawer 301 and a moisture preserving drawer 302 respectively. As shown in fig. 5 and 6, the fixing frame 90 includes a back plate 94, and the front panel of the temperature changing drawer 301 or the humidity maintaining drawer 302 and the back plate 94 form front and rear surface walls of the corresponding cavity 93 together so as to ensure the tightness of the cavity 93. The back plate 94 defines an air guiding structure 941 having one end aligned with at least one air outlet of the air duct assembly 20 and another end extending above the temperature change drawer 301.

In yet another embodiment, as shown in FIG. 1, a mount 90 is secured within the refrigerator cabinet 50. Specifically, fixed frame 90 is fixed, and temperature change drawer 301 and the other drawer can be pulled and pulled respectively with respect to fixed frame 90. The fixing frame 90 has simple structure and low processing cost. In one embodiment, the drawer that is co-assembled with temperature change drawer 301 to mount 90 is a moisturizing drawer 302.

In one embodiment, as shown in fig. 1 to 4, the fixing frame 90 includes:

a shelf 91, both sides of which are connected to the inside of the refrigerator cabinet 50;

a bracket 92 fixed below the shelf 91 for dividing a region below the shelf 91 to form two frame regions; the left and right sides of the bracket 92 are respectively provided with a sliding rail for respectively sliding connection with one side wall of the two drawers. Specifically, a drawer assembled together with temperature change drawer 301 in holder 90 is taken as moisturizing drawer 302, and both sidewalls of temperature change drawer 301 and moisturizing drawer 302 are slidably connected to bracket 92 and refrigerator container 50, respectively. The fixing frame 90 is formed by assembling the shelf 91 and the bracket 92, so that the structural design of the fixing frame 90 can be simplified, and the occupied space of the fixing frame 90 can be reduced; the shelf 91 and the bracket 92 are separately processed to simplify the complexity of the die and reduce the cost; in addition, the weight of the temperature changing drawer 301 and the moisture keeping drawer 302 is transmitted to the two side walls of the refrigerator container through the shelf 91 on one hand and to the bottom wall of the refrigerator container through the bracket 92 on the other hand, so that the bearing weight of the two side walls of the refrigerator container is reduced, and the requirement on the structural strength of the refrigerator container is further reduced. The outer walls of air duct assembly 20 form an isolation structure with temperature change drawer 301 and shelf 91 to block the flow of air within temperature change drawer 301 to the return air area.

Further, as shown in fig. 2, the bottom end of the bracket 92 is inserted into the refrigerator container 50, and the assembly is simple and detachable. In one embodiment, the bottom end of the shelf 91 is provided with a limit groove 913, and the top end of the bracket 92 is clamped into the limit groove 913; the refrigerator container 50 internal surface is equipped with a plurality of mounting grooves, and the support 92 bottom is equipped with a plurality of second joint protruding 921, and the protruding 921 looks joint of second joint is protruding 921 with the second joint to the bottom of fixing support 92.

In an embodiment, as shown in fig. 1, the temperature changing drawer 301 includes a first box 31, a relief opening 311 is disposed on at least one side wall of the first box 31 facing the refrigerator container 50, and the relief opening 311 corresponds to at least one air outlet position of the air duct assembly 20 of the refrigerator, so that cold air at the air outlet blows into the storage cavity.

In an embodiment, the relief opening 311 is a through slot or a notch structure, and is simple to open.

Further, the relief opening 311 is disposed on a side wall of the first box 31 facing away from the refrigerator door. Specifically, the air outlet of the air duct assembly 20 is disposed facing the refrigerator door to generate a cooling air flow from inside to outside of the storage space of the refrigerator. The abdication opening 311 is arranged on a side wall of the first box body 31, which is opposite to the refrigerator door body, so that the vertical distance between the abdication opening 311 and the air outlet of the air duct assembly 20 is shortened, and the air supply distance is further shortened, so that the cold air input speed in the first box body 31 is accelerated. Further, the relief opening 311 is disposed near the top of the first box 31, so as to prevent the air supply at the relief opening 311 from being affected by the height of the stored articles in the first box 31, thereby affecting the air supply effect. Further, the upper part of the abdication opening 311 is open, so that the processing is convenient; in addition, the setting of the abdication opening 311 makes full use of the top end space of the side wall of the first box 31 to avoid the storage of the storage articles.

In one embodiment, both side walls of the first case 31 are partially or entirely inclined upward in a direction toward the refrigerator door. Specifically, the air continuously blows into the first box 31 at the first air outlet 211 of the air duct assembly 20, which has a downward pressing effect on the air in the first box 31, and reduces the speed of the air flow overflowing. Since the wind from the first air outlet 211 blows from the rear portion to the front portion in the first box 31, the airflow velocity decreases when the airflow flows to the front portion of the first box 31. The flow velocity of the air blown into the first air outlet 211 is reduced at the position in the first box body 31, which is close to the refrigerator door body, and the air at the position is easier to rise, so that the air overflow velocity in the region of the position is delayed by increasing the heights of the two side walls of the first box body 31 at the position.

In one embodiment, as shown in fig. 1, the rack 91 has a frame structure, and a support portion 914 is disposed in a frame area thereof for placing the glass shelf 80; temperature and

moisture drawers

301, 302 are provided below shelf 91. The upper part of the shelf 91 is used for carrying articles through the glass shelf 80, the lower part of the shelf 91 is used for storing articles through the temperature changing drawer 301 and the moisture keeping drawer 302, the bearing force of the shelf 91 is fully utilized to divide and form different storage areas, and the inner space of the refrigerator container is fully utilized.

In an embodiment, as shown in fig. 1 and 7, the temperature changing drawer 301 further includes a first cover 32, where the first cover 32 is disposed between the first box 31 and the shelf 91, and a gap is left between the first cover 32 and the first box 31 to allow the first box 31 to be pulled out; wherein,,

a concave cavity 321 is formed on one surface of the first cover body 32 facing the first box body 31 in a concave manner; when the first box 31 is folded in the refrigerator, the concave cavity 321 cover plate forms an enclosing structure above the first box 31 to delay the overflow of cold air. Specifically, by forming the cavity 321 on the first cover 32, when the first box 31 is located below the first cover 32, the air in the first box 31 rises to the assembling gap between the first box 31 and the first cover 32, and the space of the cavity 321 is far greater than the size of the assembling gap, so that the air rising to the assembling gap preferentially flows to a spacious place, i.e. flows to the cavity 321, so as to delay the air in the first box 31 from overflowing from the assembling gap between the first box 31 and the first cover 32, i.e. reduce the overflowing speed of the cold air in the first box 31, and further improve the sealing effect on the first box 31.

In order to prevent the first case 31 from colliding with the first cover 32 during the drawing, and to improve the sealing property of the first cover 32 to the first case 31, the gap between the first cover 32 and the first case 31 is 1mm-2mm.

In an embodiment, the first cover 32 is fixed on the shelf 91, so that the installation is convenient, the arrangement of additional fixing parts is omitted, and the space occupation is reduced.

In one embodiment, the first cover 32 is lifted under the shelf 91 so as not to interfere with the placement of the glass shelf panel 80.

Further, as shown in fig. 1, the first cover 32 is provided with a plurality of first clamping protrusions 322 to be clamped to the shelf 91, which is easy to assemble and disassemble, and is convenient to replace or repair the first cover 32.

Further, at least front and rear ends of the left and right sidewalls of the first cover 32 are respectively provided with a first clamping protrusion 322 to form a stable supporting force.

In a specific embodiment, as shown in fig. 7, 8 and 9, two first clamping protrusions 322 are respectively disposed on two opposite side walls of the first cover 32, and a matching clamping groove is disposed below the shelf 91, and the first clamping protrusions 322 are clamped into the clamping grooves to realize clamping of the first cover 32. In order to simplify the assembly structure while the installation is stable, the lower parts of the left side and the right side of the shelf 91 are respectively provided with a first clamping groove 911 and a second clamping groove 912, and the first clamping groove 911 and the second clamping groove 912 are respectively close to two ends of the side wall of the shelf 91 so as to clamp two ends of the side wall of the first cover 32.

Further, as shown in fig. 9, in order to reduce the difficulty of assembling and disassembling, the first clamping groove 911 includes a first abutting arm 9111 and a second abutting arm 9112, where the first abutting arm 9111 and the second abutting arm 9112 are vertically arranged to abut against front and rear surfaces of a first clamping protrusion 322 on one side wall of the first cover 32 respectively, so as to limit the movement of the first cover 32 along the drawing direction; the second clamping groove 912 includes a third abutting arm 9121 and a fourth abutting arm 9122, where the third abutting arm 9121 and the fourth abutting arm 9122 are laterally disposed to abut against the upper and lower surfaces of the other first clamping protrusion 322 on the same side wall of the first cover 32, so as to limit the up and down movement of the first cover 32. The first cover 32 is limited to move in any direction by limiting the first clamping groove 911 and the second clamping groove 912; in addition, the structural design of the first clamping groove 911 and the second clamping groove 912 reduces the clamping force to the corresponding first clamping protrusion 322, thereby facilitating assembly and disassembly.

Further, as shown in fig. 7 and 8, a reinforcing rib 325 is provided on the inner surface of the first cover 32 at a position corresponding to the first engaging protrusion 322. Specifically, when the first cover 32 is lifted below the shelf 91 by the first clamping protrusion 322, the first clamping protrusion 322 bears the weight of the first cover 32, the root of the first clamping protrusion 322 is pulled, and the reinforcing rib 325 is arranged to buffer the deformation of the root of the first clamping protrusion 322 caused by pulling, so as to reduce the damage probability of the structure around the root of the first clamping protrusion 322.

In an embodiment, at least one side wall of the cavity 321 surrounds the outer wall of the first box body 31, and the cool air in the first box body 31 needs to bend to enter a channel between the side wall of the cavity 321 and the outer wall of the first box body 31 in the flowing process and then overflows, so as to increase the difficulty of leakage of the cool air in the first box body 31 from the assembling gap between the first box body 31 and the first cover body 32. Specifically, one, two, three, or four sidewalls of the cavity 321 may extend outside the corresponding sidewalls of the first case 31, so as to increase the effect of preventing the cool air of the first case 31 from overflowing.

In one embodiment, as shown in fig. 8, the left and right sidewalls of the cavity 321 are covered over the left and right sidewalls of the first case 31. Specifically, the left and right sidewalls of the cavity 321 are a first sidewall 323 and a second sidewall 324, and during the drawing motion process of the first box body 31, the sidewalls of the two sides of the first box body are respectively moved relative to the first sidewall 323 and the second sidewall 324, so that a gap is required between the two sidewalls of the first box body 31 and the left and right sidewalls of the cavity 321 for facilitating the drawing of the first box body 31, and if the first sidewall 323 and the second sidewall 324 are designed to surround the two sides of the first box body 31, the left and right dimensions of the temperature changing drawer 301 are increased, which causes waste of the storage space of the refrigerator. The first side wall 323 and the second side wall 324 are designed above the first box body 31, so that the first box body 31 can be pulled out and the left and right dimensions of the first cover body 32 can be controlled. Further, in order to reduce the overflow speed of the cold air in the first box 31, a side arm of the first cover 32 near the refrigerator container 50 surrounds an outer wall of the first box 31 near the refrigerator container 50.

Further, as shown in fig. 7, the lower end surfaces of the left and right sidewalls of the cavity 321 extend along the upper end surface contours of the two sidewalls of the first box 31, so as to balance the distances between different parts of the lower end surfaces of the left and right sidewalls of the cavity 321 and the upper surfaces of the two sidewalls of the first box 31, i.e. control the height of the assembly gap to be consistent, so as to control the overflow of the cold air. In an embodiment, the two side walls of the first box 31 are partially or completely inclined upwards along the direction towards the refrigerator door, and the lower end surfaces of the left and right side walls of the cavity 321 are also inclined upwards, so that a curved or bent passageway is formed between the upper end surfaces of the two side walls of the first box 31 and the lower end surfaces of the left and right side walls of the cavity 321, thereby increasing the difficulty of the passageway in passing through the air flow and further slowing down the air overflow.

In one embodiment, as shown in fig. 8, the cavity 321 has a side-to-side dimension slightly smaller than the side-to-side dimension of the storage cavity of the first container 31. Specifically, the contour of the periphery of the concave cavity 321 is slightly reduced relative to the contour of the periphery of the storage cavity, so as to play a role in drainage. When the cold air in the first box body 31 rises to the position of the assembling gap between the cold air and the first cover body 32, the cold air hits the inner surface of the concave cavity 321 to change the flowing direction so as to flow towards the middle position of the concave cavity 321, and then the probability that the cold air rising in the first box body 31 flows into the assembling gap is reduced.

Further, as shown in fig. 7 and 8, the left and right side walls of the cavity 321 respectively extend in a direction away from the cavity 321 to form an extension edge. Specifically, rails are required to be arranged on two sides of the first box 31 to be slidably connected with the refrigerator liner 50 so as to realize drawing; the track of the conventional first box is disposed near the top of the first box 31 to provide a stable supporting force, and thus the top walls of both sides of the conventional first box 31 have a certain width. The first side wall 323 and the second side wall 324 are designed to extend to form a first extending edge 3231 and a second extending edge 3241 respectively, so as to extend the width of the channel formed by the left and right side walls of the cavity 321 and the left and right side walls of the first box 31, and further reduce the overflow speed of the cold air in the first box 31.

Specifically, by providing the air guide nozzle 10, the air guide nozzle plays a role in guiding the air flow at the first air outlet 211, and concentrates the air flow to blow into the temperature changing drawer 301, so that the air supply effect is improved, and the temperature changing speed of the temperature changing drawer 301 is further improved. In addition, because the air duct assembly 20, the temperature changing drawer 301 and the fixing frame 90 are relatively large in size and relatively complex in structure, if the air guide structure is directly formed on the air duct assembly 20, the temperature changing drawer 301 or the fixing frame 90, the processing die of the air duct assembly 20, the temperature changing drawer 301 or the fixing frame 90 needs to be changed, so that the cost is increased; and after the structure of the air duct assembly 20 or the temperature changing drawer 301 or the fixing frame 90 is changed, the application range is reduced. The air guide nozzle 10 is simple and small in structure, replaces a scheme of directly arranging an air guide structure on an air duct assembly or a temperature changing drawer or a fixing frame, improves air supply effect, reduces structural change of the air duct assembly or the temperature changing drawer or the fixing frame, and reduces refrigerator change cost.

In an embodiment, the air guide nozzle 10 is fastened to the air duct assembly 20, and the air guide nozzle 10 is convenient to assemble and disassemble. In addition, the first air outlet 211 of the air duct assembly 20 can be matched with the air guide nozzle 10, and the air guide nozzle 10 can simplify the structural design of the air duct assembly 20.

Further, as shown in fig. 10 and 13, the air nozzle 10 is provided with a plurality of abutting portions 13 for abutting against the side wall of the first air outlet 211. Specifically, the air guide nozzle 10 is buckled at the first air outlet 211 through the matching of the buckle 12 and the abutting part 13 with the outline of the first air outlet 211. The abutting portion 13 is provided to reduce the number of the buckles 12, so as to reduce the assembling and disassembling force of the profile of the air guide nozzle 10 and the profile of the first air outlet 211, and facilitate assembling and disassembling of the air guide nozzle 10. In a specific embodiment, the number of the buckles 12 is four, two sets of buckles are opposite in position; the number of the abutting portions 13 is two, and the positions are opposite. The four buckles 12 respectively clamp the peripheral outlines of two opposite sides of the first air outlet 211, and the two abutting parts 13 respectively abut against the other two opposite side walls of the first air outlet 211, so that the wind guide nozzle 10 is buckled.
