Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and in particular relates to a refrigerator which is convenient for performing zoning refrigeration. Background Art

[0002] A freezer is a common refrigeration equipment. Because it has a large storage space inside and can store various types of items at the same time, it is widely used in people's daily life and work.

[0003] To facilitate the classification and storage of different types of items, technicians in this field usually install partitions inside the refrigerator to divide the storage cavity into multiple different areas, and add hanging baskets or trays in each area to enable each area to be used in layers, thereby meeting the actual usage needs of users.

[0004] However, after the traditional refrigerator is divided into zones, it is impossible to regulate the cooling capacity of each zone, so the items stored in different zones will be subjected to the same freezing effect. In actual use, since users will place items into the refrigerator at intervals, the cooling capacity cannot be concentrated to freeze the newly placed items, resulting in a waste of cooling capacity and affecting the freezing efficiency of the items. If the refrigerator is improved through the existing zone temperature control technology, the manufacturing cost of the refrigerator will be significantly increased, reducing the economic benefits of the manufacturer.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] A refrigerator that is convenient for partition freezing, the structure of which can be Figure 1-Figure 9 In this embodiment, the refrigerator for zoned freezing includes: a cabinet body 1, a partition 2, a flow-blocking basket and a flow-guiding basket, wherein a storage cavity is provided inside the cabinet body 1, and the partition 2 is detachably arranged inside the storage cavity. The storage cavity can be divided into a weak cooling area 13 and a strong cooling area 14 by the partition 2, and the flow-blocking basket is detachably arranged inside the weak cooling area 13, and the flow-guiding basket is detachably arranged inside the strong cooling area 14. In addition, an openable cabinet door should be provided on the top of the cabinet body 1, so that the user can open or close the storage cavity by opening and closing the cabinet door.

[0040] When in use, the user can place the items in the weak cooling area 13 or the strong cooling area 14 according to the cooling demand for freezing the items (that is, items that require more cooling or need to be frozen quickly are placed in the strong cooling area 14, and items that require less cooling or have been frozen are placed in the weak cooling area). The built-in refrigeration system of the cabinet 1 can generate cooling through the circulation of refrigerant, and use gas as a cooling medium to transport the cooling to the loading tray, thereby achieving freezing of items. Accordingly, the user can also adjust the position of the partition 2 and increase or decrease the number of flow-blocking loading baskets and flow-guiding loading baskets according to actual needs, so that the volume of the weak cooling area 13 and the strong cooling area 14 matches the actual needs.

[0041] It should be noted that the refrigeration system described in this embodiment is a mature existing technology. It is also a common practice for technical personnel in this field to generate cold through a refrigeration system and use gas as a cooling medium to transport cold. Therefore, the specific structure and related working principles for realizing the above functions will not be repeated in this article.

[0042] In order to facilitate the gas carrying cold energy (hereinafter referred to as cold air) to enter the storage cavity, an inlet air channel 11 and an outlet air channel 12 are respectively provided in the two opposite side walls of the cabinet 1, and an inlet cutout 111 connected to the inlet air channel 11 and an outlet air channel 12 are provided on the inner wall of the storage cavity. Accordingly, in order to control the flow of cold air in the weak cooling area 13 and the strong cooling area 14, so that the weak cooling area 13 and the strong cooling area 14 form a difference in cold energy distribution, the present embodiment is provided with an inlet cutout 311 and an outlet cutout 321 on the flow blocking carrier basket, and an inlet guide hole 431 and an outlet guide hole 441 on the flow guiding carrier basket, and the gas flow cross-sectional area in the inlet guide hole 431 is larger than the gas flow cross-sectional area in the inlet cutout 311, and the gas flow cross-sectional area in the outlet guide hole 441 is larger than the gas flow cross-sectional area in the outlet cutout 321.

[0043] After the flow-blocking basket and the flow-guiding basket are correspondingly loaded into the weak cooling area 13 and the strong cooling area 14, the flow-blocking basket will block the air inlet 111 and the air outlet 121 in the weak cooling area 13, and the flow-guiding basket will block the air inlet 111 and the air outlet 121 in the strong cooling area 14. When the device is started, the cold air in the inlet air channel 11 will enter the weak cooling area 13 and the strong cooling area 14 along the inlet slot 311 and the inlet guide hole 431, and flow back to the outlet air channel 12 along the outlet slot 321 and the outlet guide hole 441, thereby reducing the internal temperature of the weak cooling area 13 and the strong cooling area 14, and achieving the purpose of freezing the objects. Since the gas flow cross-sectional area of ​​the air inlet guide hole 431 is larger than the gas flow cross-sectional area of ​​the air inlet groove 311, and the gas flow cross-sectional area of ​​the air outlet guide hole 441 is larger than the gas flow cross-sectional area of ​​the air outlet groove 321, during actual operation, the cold air flow in the strong cooling area 14 will be greater than the cold air flow in the weak cooling area 13. In this way, the strong cooling area 14 can obtain more cold air distribution, so that the device can concentrate cold air to freeze the items stored in the strong cooling area 14, thereby improving the freezing efficiency of the items in the middle of the strong cooling area 14.

[0044] like Figure 7 and Fig.10 As shown, the flow-blocking cargo basket in this embodiment may include: an air inlet flow-blocking bar 31, an air outlet flow-blocking bar 32 and a flow-blocking tray 34, wherein the bottom surfaces of the air inlet flow-blocking bar 31 and the bottom surfaces of the air outlet flow-blocking bar 32 are respectively connected to the flow-blocking tray 34 through connecting rods 33. When the user puts items into the flow-blocking cargo basket, the flow-blocking tray 34 can support the items, and the connecting rods 33 can constrain the items, so that the flow-blocking cargo basket has a good loading capacity for items.

[0045] like Figure 4 As shown, after the baffle basket is loaded into the weak cooling area 13, the air inlet baffle strip 31 and the air outlet baffle strip 32 will respectively block the air inlet cutout 111 and the air outlet cutout 121 in the weak cooling area 13. The air inlet notch 311 should be arranged on the side wall of the air inlet baffle strip 31 close to the air inlet notch 111, and the air outlet notch 321 should be arranged on the side wall of the air outlet baffle strip 32 close to the air outlet notch 121, so as to facilitate the cold air to enter and exit the weak cooling area 13.

[0046] In order to make full use of the internal space of the weak cooling area 13, the user can also place items under the flow-blocking basket. Accordingly, in order to facilitate freezing of the items under the flow-blocking basket, the flow-blocking tray 34 can also be provided with a first connecting groove 342 and a second connecting groove 341, and the first connecting groove 342 should be aligned with the air inlet groove 311, and the second connecting groove 341 should be aligned with the air outlet groove 321, so that the cold air can smoothly enter and exit the area below the flow-blocking basket along the first connecting groove 342 and the second connecting groove 341.

[0047] Optionally, in order to improve the structural strength and article loading capacity of the flow-blocking basket, the flow-blocking basket may further include a first lifting rod 35 and a first blocking rod 36. Specifically, the two ends of the first lifting rod 35 should be connected to the air inlet blocking strip 31 and the air outlet blocking strip 32 respectively, the top end of the first blocking rod 36 should be connected to the first lifting rod 35, and the bottom end of the first blocking rod 36 should be connected to the flow-blocking tray 34. When in use, the first blocking rod 36 can block the articles in the flow-blocking basket to prevent the articles from falling outwards, and the first lifting rod 35 can not only support the air inlet blocking strip 31 and the air outlet blocking strip 32 to prevent the flow-blocking basket from being deformed due to too many articles loaded, but also provide a gripping basis for the user when the flow-blocking basket needs to be moved, thereby improving the convenience of using the flow-blocking basket.

[0048] like Figure 8 , Fig. 9 and Fig.11 As shown, the guide basket in this embodiment may include: an inlet guide bar 41, an outlet guide bar 42 and a guide tray 45, wherein the bottom surface of the inlet guide bar 41 is connected to the guide tray 45 via an inlet guide pipe 43, and the bottom surface of the outlet guide bar 42 is connected to the guide tray 45 via an outlet guide pipe 44. When the user puts items into the guide basket, the guide tray 45 can support the items, and the inlet guide pipe 43 and the outlet guide pipe 44 can constrain the items, so that the guide basket has a good item loading capacity.

[0049] like Figure 5 As shown, after the guide carrier basket is loaded into the strong cooling area 14, the air inlet guide strip 41 and the air outlet guide strip 42 will respectively block the air inlet cutout 111 and the air outlet cutout 121 in the strong cooling area 14. In order to allow the cold air to smoothly enter and exit the strong cooling area 14, an air inlet cavity 411 is provided inside the air inlet guide strip 41, an air inlet hole 412 is provided on the side wall of the air inlet guide strip 41 near the air inlet cutout 111, an air outlet cavity 421 is provided inside the air outlet guide strip 42, and an air outlet hole 422 is provided on the side wall of the air outlet guide strip 42 near the air outlet cutout 121. The air inlet guide pipe 43 should be connected to the air inlet cavity 411, and the air inlet guide hole 431 is set on the side wall of the air inlet guide pipe 43; the air outlet guide pipe 44 should be connected to the air outlet cavity 421, and the air outlet guide hole 441 is set on the side wall of the air outlet guide pipe 44.

[0050] When the guide basket is loaded into the strong cooling area 14, the air inlet cavity 411 is connected to the air inlet cutout 111 through the air inlet hole 412, and the air outlet cavity 421 is connected to the air inlet cutout 111 through the air outlet hole 422. Since the air inlet guide hole 431 and the air outlet guide hole 441 are respectively arranged on the side walls of the air inlet guide pipe 43 and the air outlet guide pipe 44, the cold air will flow in the article loading area in the guide basket. In this way, the contact probability between the cold air and the articles can be increased, and the freezing efficiency of the articles can be further accelerated.

[0051] Optionally, in order to improve the uniformity of distribution of cold air in the guide carrier basket and ensure that the items at various positions in the guide carrier basket obtain a good freezing effect, the air inlet guide hole 431 and the air outlet guide hole 441 can be set to multiple, and the multiple air inlet guide holes 431 are evenly arranged along the length direction of the air inlet guide pipe 43, and the multiple air outlet guide holes 441 are evenly arranged along the length direction of the air outlet guide pipe 44.

[0052] In order to fully utilize the internal space of the strong cooling area 14, the user can also place items under the guide basket. Accordingly, in order to facilitate freezing of the items under the guide basket, the bottom surface of the guide tray 45 can be provided with an air inlet communication hole 451 connected to the air inlet guide pipe 43 and an air outlet communication hole 452 connected to the air outlet guide pipe 44, so that cold air can smoothly enter and exit the area below the guide basket along the air inlet communication hole 451 and the air outlet communication hole 452.

[0053] In addition, in order to form different cooling distribution effects inside the guide carrier basket and below the guide carrier basket, the aperture of the air inlet connecting hole 451 can be smaller than the aperture of the air inlet guide hole 431, and the aperture of the air outlet connecting hole 452 can be smaller than the aperture of the air outlet guide hole 441, so that the cold air flow below the guide carrier basket is smaller than the cold air flow inside the guide carrier basket.

[0054] Optionally, in order to improve the structural strength and article loading capacity of the guide basket, the guide basket may further include a second lifting rod 46 and a second blocking rod 47. Specifically, the two ends of the second lifting rod 46 should be connected to the air inlet guide bar 41 and the air outlet guide bar 42 respectively, the top end of the second blocking rod 47 is connected to the second lifting rod 46, and the bottom end of the second blocking rod 47 is connected to the guide tray 45. When in use, the second blocking rod 47 can block the articles in the guide basket to prevent the articles from falling outwards, and the second lifting rod 46 can not only support the air inlet guide bar 41 and the air outlet guide bar 42 to prevent the guide basket from being deformed due to too many articles loaded, but also provide a gripping basis for the user when the guide basket needs to be moved, thereby improving the convenience of using the guide basket.

[0055] As an optional implementation manner of this embodiment, the device may be provided with a limiting outer edge 5 on the top of the flow-blocking carrier basket, the flow-guiding carrier basket and the partition 2, and a limiting groove 15 for accommodating the limiting outer edge 5 is provided on the inner wall of the storage cavity, so that the height position of the flow-blocking carrier basket, the flow-guiding carrier basket and the partition 2 inside the storage cavity is supported and limited by the cooperation of the limiting outer edge 5 and the limiting groove 15.

[0056] In addition, the device may be provided with a positioning protrusion 51 on the limiting outer edge 5, and a positioning groove 151 for accommodating the positioning protrusion 51 may be provided inside the limiting groove 15, so that the assembly reliability of the flow-blocking carrier basket, the flow-guiding carrier basket and the partition 2 inside the storage cavity can be improved by means of the cooperation between the positioning protrusion 51 and the positioning groove 151, thereby avoiding abnormal movement of the flow-blocking carrier basket, the flow-guiding carrier basket and the partition 2 after the assembly is completed.

[0057] The effects of the above scheme are described below:

[0058] The present embodiment provides a refrigerator that is convenient for zoned freezing. The storage cavity can be divided into a weak cooling area and a strong cooling area by a partition, and a flow-blocking carrier basket and a flow-guiding carrier basket can be used to obtain less cold air flow in the weak cooling area and more cold air flow in the strong cooling area. Therefore, without introducing a zoned temperature control system, more cold air can be distributed in the strong cooling area, so as to concentrate the cold air to freeze the items stored in the strong cooling area, thereby improving the freezing efficiency of the items in the strong cooling area.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
