Detailed Description

The technical solutions of the present application are described clearly and completely by the following specific examples, and it is obvious that the described examples are some, but not all, of the examples of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is an object of embodiments of the present invention to provide one or more refrigeration appliances 100.

The refrigerator 100 according to the embodiment of the present invention may be a refrigerator, a freezer, or a red wine, which can provide a relatively low temperature storage environment for a user.

Fig. 1 shows a schematic cross-sectional structure of a refrigeration device 100 provided by an embodiment. Fig. 2 shows a partially enlarged cross-sectional view of the refrigeration device 100 provided by an embodiment.

Although fig. 1 illustrates a refrigeration appliance 100 having two doors and two storage spaces, the present invention can be applied to other refrigeration appliances 100 having a different number of doors 6, or a different distribution of doors 6 and a different number of storage spaces, as long as it does not clearly conflict with the present invention. Accordingly, based on the description of the embodiments of the present invention, the technical effects of the present invention applied to other forms of the refrigeration appliance 100 are also expected.

The refrigerator 100 includes an outer case and an inner storage space, and a door 6 coupled to the case and capable of closing the storage space. The refrigeration appliance 100 also has a refrigeration provider for providing it with refrigeration. For example, the cooling capacity providing unit may be a magnetic refrigerator, a semiconductor refrigerator, or a refrigerant evaporation and absorption type refrigerator, or the like. The refrigeration providing unit can be used to directly supply the refrigeration device 100 with refrigeration, and can also be used to supply the refrigeration device 100 with refrigeration in an air cooling mode or a mixed cooling mode. The following description is given by way of example only of an embodiment in which the cooling energy is provided to the refrigeration appliance 100 in the form of air cooling, which also can be applied to other forms of refrigeration appliances 100 in which cooling energy is provided, with the exception of the explicit conflict with the present invention.

A partition 10 is provided in the storage space of the refrigerator 100, and the partition 10 divides the storage space into a second storage space 2 and a first storage space 1 which are distributed vertically. In other possible embodiments, one or more of the storage spaces may be separated by one step.

The refrigerator 100 further includes a drawer 20 for storing articles in the storage space, and the drawer 20 has a box shape opened at an upper side. The drawer 20 has a bottom wall 23, a front wall 21 and side walls 22 extending upwardly from the edges of the bottom wall 23, the front wall 21, side walls 22 and bottom wall 23 defining a storage space of the drawer 20. The side wall 22 is connected to the front wall 21 and extends rearward from the front wall 21; at the rear end of the side wall 22, there may also be another side wall 22 connected to the bottom wall 23, disposed opposite the front wall 21. The bottom wall 23, side walls 22 and storage space of the drawer 20 are all located below the partition 10.

The drawer 20 has a front wall 21 extending at a higher height than the side walls 22 and the front wall 21 is located outside the vertical projection of the partition 10. The front wall 21 extends upward to the front of the partition 10 so that the upper end 211 of the front wall 21 at least partially overlaps the partition 10 in the front-rear direction; in other words, the upper end 211 of the front wall 21 at least partially shields the partition board 10 in the front-rear direction. On the front wall 21 of the drawer 20, a vent hole 11 is further formed, and the vent hole 11 may allow air to flow therethrough. In this manner, although the front end of the partition 10 is shielded by the front wall 21 of the drawer 20, air may flow into or into the area under the partition 10 through the ventilation holes 11 so that the area under the partition 10 may participate in heat exchange in the storage space. Further, the vent hole 11 is located between the top of the side wall 22 and the upper edge of the partition 10 in the vertical direction, so that the air path is relatively unobstructed and the wind resistance and pressure loss are smaller.

Normally, the user is positioned in front of the refrigeration device 100 when using the refrigeration device 100. With the configuration of the present embodiment, the gap formed between the partition 10 and the drawer 20 is conventionally blocked by the front wall 21 of the drawer 20, and the visual experience of the refrigeration appliance 100 is better.

In one embodiment, a first storage space 1 is formed in an area below the partition 10, a second storage space 2 is formed in an area above the partition 10, and the side wall 22, the bottom wall 23, and the storage compartment 3 of the drawer 20 are located in the first storage space 1. The drawer 20 may be withdrawn from the first storage space 1 or slid in a forward direction to expose the storage space to a user for the user to put in and take out items. A gap 12 is further formed between the upper end 211 of the front wall 21 and the front end of the partition 10, and the gap 12 communicates the first storage space 1 with the second storage space 2, and on this basis, the cold air in the second storage space 2 may flow into the first storage space 1 through the gap 12, or the cold air in the first storage space 1 may flow into the second storage space 2 through the gap 12. The flow of the cold air in the first and second storage spaces 1 and 2 can achieve a certain degree of heat exchange. In this way, although the front end of the partition 10 and the gap between the partition 10 and the drawer 20 are blocked by the front wall 21 of the drawer 20, heat exchange between the first storage space 1 and the second storage space 2 can be achieved, and the air path is shorter and the heat exchange efficiency is higher.

Further, the first storage space 1 is located upstream of the flow of the cool air, a part of the cool air in the first storage space 1 may flow out of the first storage space 1 from the vent hole 11 and then flow into the second storage space 2, and a part of the cool air in the first storage space 1 may flow into the second storage space 2 from the first storage space 1 from the gap 12. Therefore, the flow area of the gas path is further increased in a limited area, the wind resistance and the pressure loss are reduced, and the heat exchange efficiency is higher.

As a modification, the second storage space 2 may be located upstream of the first storage space 1, and the cool air in the second storage space 2 may flow into the first storage space 1 through the gap 12 and the vent hole 11.

In a possible embodiment, the door 6 is spaced apart from the front wall 21 to form a second air duct 32, the vent hole 11 is communicated with the second air duct 32, and the second air duct 32 is communicated with the second storage space 2. In this way, at least part of the cool air in the first storage space 1 may flow into the second storage space 2 through the ventilation hole 11 and the second duct 32. The air path design does not need to additionally generate special shape requirements or increase accessories, and is low in cost and easy to realize.

The air inlet end of the second air duct 32 may be communicated to a cool air supply region of the refrigerator 100, such as the evaporator 5 compartment. At this time, the evaporator 5 can directly provide cooling capacity to the second storage space 2, and the cold air flowing out of the first storage space 1 through the vent 11 can supply cold air to the second storage space 2 by using the second duct 32, thereby simplifying the air path structure and the product cost.

In a specific embodiment, the refrigeration appliance 100 further comprises a cover plate 24 for closing the storage compartment 3, the cover plate 24 also being located in the first storage space 1 below the partition 10. The cover plate 24 may control air exchange between the storage chamber 3 and the first storage space 1, so as to control humidity and temperature in the storage chamber 3. When the cover plate 24 covers the storage cavity 3, a certain gap 12 is formed between the cover plate 24 and the partition plate 10, the gap 12 is used as a part of the first air duct 31 between the partition plate 10 and the cover plate 24, and cold can still be transmitted into the storage cavity 3 when cold air flows through the drawer 20 and the cover plate 24. The ventilation hole 11 can be communicated with the first air duct 31, so that the cold air can provide cold energy to the articles in the storage chamber 3 no matter the cold air flows into the first air duct 31 through the ventilation hole 11 or flows out of the first air duct 31 through the first air duct 31 and the ventilation hole 11.

Further, a first air inlet 13 for introducing cool air into the first storage space 1 is formed in the first storage space 1. The cool air can flow into the first storage space 1 through the first air inlet 13 and flow out of the first storage space 1 through the first air duct 31 and the ventilation hole 11, and in the process, the inside of the storage cavity 3 of the drawer 20 is cooled. First air intake 13, first wind channel 31 and ventilation hole 11 can be located a straight line, and so, the wind path is straighter, shorter, and windage and pressure loss are littleer, also can avoid cold air and drawer 20 long-term contact to make the interior temperature of storing chamber 3 hang down excessively. As a modification, the first air inlet 13, the first air duct 31 and the ventilation hole 11 may not be strictly located on a straight line, but end surfaces of the two adjacent air inlets are overlapped with each other, which may slightly increase wind resistance and pressure loss; alternatively, such a solution may be adopted when it is desired to further reduce the temperature in the storage chamber 3.

Further, the end of the cover plate 24 close to the first air inlet 13 is bent toward the bottom wall 23 to increase the area of the first air duct 31 facing the first air inlet 13, so that the cool air can flow into the first air duct 31 more smoothly.

In a possible embodiment, a third air duct 33 is further formed below the bottom wall 23 of the drawer 20, and a second air inlet 14 is further formed on a wall of the first storage space 1. In this way, the cold air can cool the storage chamber 3 from below even when flowing through the third air duct 33. The second air inlet 14 faces the third air duct 33, and one end of the bottom wall 23 close to the second air inlet 14 is inclined upward to increase the area of the third air duct 33 facing the second air inlet 14, so that the cold air can flow into the third air duct 33 more smoothly.

Further, the air inlet ends of the first air duct 31 and the third air duct 33 are both communicated to the vicinity of the cold source, the air outlet end of the third air duct 33 is communicated with the air inlet end of the second air duct 32, and the air outlet end of the first air duct 31 can be communicated with the second air duct 32 and/or the second storage space 2 by any of the above manners. So configured, the drawer 20 can be cooled well, and the wind resistance and pressure loss are smaller, and the heat exchange efficiency of the refrigeration appliance 100 is higher.

The refrigeration device 100 further comprises an air pressure chamber 4, and the pressure of the air flow flowing through the air pressure chamber 4 is raised to circulate in the refrigeration device 100 smoothly, for example, the air flow pressure can be raised by arranging a fan in the air pressure chamber 4. The wind pressure is strong to communicate with the first storage space 1 through the first wind inlet 13 and/or the second wind inlet 14. The air pressure chamber 4 may be located behind the first storage space 1, so that the air pressure chamber 4 is closer to the first storage space 1 having relatively complicated air paths, and the cool air may smoothly pass through the first storage space 1 and flow into the second storage space, resulting in a good cooling effect in both the first storage space 1 and the second storage space 2.

In a specific embodiment, a return air opening 9 is provided in an upper portion of the second storage space 2. The cold air flowing from the first storage space 1 into the second storage space 2 can flow out of the storage space from the return air opening 9. Further, a tray 77 is further provided in the second storage space 2, and the tray 77 can further divide the second storage space 2, thereby improving space utilization. Meanwhile, since the shelf 77 slows down the flow rate of the air flow to some extent, the second storage space 2 can more sufficiently exchange heat with the cold air. The tray 77 is spaced apart from the rear wall of the second storage space 2 to allow the cool air to flow therethrough. As apparent from the above description, the cool air is introduced into the second storage space 2 from the front end of the second storage space 2, and the shelf 77 is spaced apart from the rear wall at the rear end thereof, so that the cool air can be induced to pass through the second storage space 2 upward and rearward, the passing area is wider, and the cooling effect of the second storage space 2 is more excellent. As a modification, the shelf 77 may be provided at its rear end with a through-flow for air to pass through. Further, a return air opening 9 is provided at the intersection of the top wall and the rear wall of the second storage space 2.

FIG. 1 shows an embodiment in which partition 10 is an insulated partition and shelf 77 is a non-insulated partition. However, in order to practice the present invention, the heat insulation function is not necessary or excluded for the partition 10 or the tray 77, and therefore, to some extent, the partition 10 and the tray 77 may be both heat insulation or non-heat insulation, or the partition 10 may be non-heat insulation and the tray 77 may be heat insulation. Of course, if it is actively pursued that the first storage space 1 and the second storage space 2 have different storage temperatures, it is preferable that the partition 10 is a kind of heat insulating member.

In a particular embodiment, the upper end 211 of the front wall 21 of the drawer 20 is configured as a handle 212 of the drawer 20, and a user can pull the drawer 20 forward by pulling the handle 212 to expose the storage compartment 3. In this way, the handle 212 is guided to the front of the partition 10. In other embodiments, pull 212 has a gap 12 with the front end of baffle 10.

The handle 212 may include a pulling portion 212b and a connecting portion 212a, the connecting portion 212a extends upward, the pulling portion 212b is connected to the connecting portion 212a, and a free end of the pulling portion 212b is bent or folded downward from the connecting portion 212a in a direction away from the connecting portion 212a for pulling and holding by a user. Wherein, the vent hole 11 is formed at the connection portion 212a. With such an arrangement, the handle 212 can not only play a basic pulling role, but also shield the gap 12 between the drawer 20 and the partition board 10, so that the drawer has two purposes, and has positive effects on cost reduction and/or space utilization rate improvement.

In a possible embodiment, the connecting portion 212a extends upward while inclining rearward, and the front end surface of the pulling portion 212b is flush with the front end surface of the front wall 21. In this way, the pull handle 212 occupies a dimension in the depth direction of the drawer 20 as small as possible while providing a sufficient pulling space, and the space utilization ratio is high. In addition, in the case of the second air duct 32, the air flow through the second air duct 32 is not obstructed by the pull handle 212.

In a specific embodiment, the pulling and holding portion 212b is bent or folded to the front of the vent hole 11, and the pulling and holding portion 212b covers the vent hole 11 entirely or partially in the front-to-rear direction. With this arrangement, since the connection portion 212a and the pulling portion 212b are spaced apart from each other, air can smoothly flow through the ventilation hole 11 even though the pulling portion 212b is located in front of the ventilation hole 11; moreover, due to the shielding of the pulling and holding part 212b, the user cannot easily see the vent hole 11, and the visual effect is further improved.

As a modification, the forward projection of the vent hole 11 is located outside the pulling and holding portion 212b, in other words, the pulling and holding portion 212b is curved in the front-rear direction so as not to block the vent hole 11. In this way, the obstruction of the airflow by the pulling portion 212b is further reduced. The wind resistance and pressure loss are smaller.

The dashed lines with arrows in fig. 2 illustrate the direction of flow of the gas stream in one embodiment of the invention.
