Abstract
Description
Technical Field
[0001] This utility model relates to the fields of freezing, refrigeration and thawing, and in particular to a thawing cabinet that can achieve uniform thawing. Background Technology
[0002] A freezer is a device that can quickly freeze items (mainly food). Its principle is to use a fan to blow the cold air generated by the evaporator to all parts of the cabinet, so that the items placed in the cabinet can be cooled down until they are frozen. In some cases, it is necessary to quickly thaw items that are already frozen, so a defrost cabinet was developed. The structure and principle of a defrost cabinet are similar to those of a freezer. It uses a fan to blow the heat generated by the heating device to all parts of the cabinet, so that the items placed in the cabinet can be heated up quickly until they are thawed.
[0003] Traditional freezers have air vents arranged in an array on the back panel to ensure even distribution of hot air within the freezer cavity. However, in practice, a large number of items to be thawed are piled on the racks. To improve efficiency, operators often place a large number of items on the racks at once. These items may have no gaps (or very small gaps) between them, or they may directly block the air vents, thus hindering or altering the flow of hot air. This causes items near the air vents to thaw earlier due to absorbing more heat, while other areas of the freezer are unable to circulate hot air due to the obstruction of the items, prolonging the thawing time of items in those areas and resulting in uneven thawing.
[0004] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by proposing a defrosting cabinet with a simple structure, ingenious design, and reasonable layout, capable of achieving rapid and efficient uniform defrosting.
[0006] The technical solution of this utility model is: a defrosting cabinet capable of uniform defrosting, comprising a cabinet body 1, with a cabinet door on the cabinet body 1, characterized in that: a top plate is provided on the top of the cabinet body 1, and a back plate 2 is provided at the rear, forming an air duct 3 between the top plate and the back plate 2 and the cabinet body 1, the inlet of the air duct 3 being opened on the top plate, and a fan 4 being provided at the inlet of the air duct 3, an evaporator 5 and a heater 6 being provided inside the air duct 3, and multiple rows of longitudinally evenly spaced air outlets are provided on the back plate 2, each air outlet row consisting of multiple air outlets 7.
[0007] The inner wall of the cabinet 1 is provided with longitudinally distributed support columns 8, and multiple sets of support blocks 9 are provided on the support columns 8. The support blocks 9 support a grid frame.
[0008] The aforementioned space frame includes an outer frame 10, within which multiple equally spaced support ribs 11 are arranged. All the support ribs 11 together form a support surface. At the tail of the outer frame 10, an upper rear stop rib 12 is provided on the top surface of the support surface. Multiple sets of limiting stop rib pairs are also provided on the top surface of the support surface, with a spacing of H between adjacent limiting stop rib pairs. Each pair of limiting stop ribs consists of two limiting stop ribs 13. Side stop ribs 14 are provided on both sides of the outer frame 10, and the spacing between each side stop rib 14 and the nearest limiting stop rib 13 is also H.
[0009] The height of the multiple air outlet rows is matched one-to-one with the height of the multiple grid frames, and the same air outlet row includes multiple air outlet groups. The distance between adjacent air outlet groups is H, and each air outlet group consists of multiple air outlets 7 distributed at equal intervals. At the same time, the horizontal position of each air outlet group corresponds to the position of a pair of limiting baffles 13.
[0010] The outer frame 10 is also provided with a lower rear baffle 15 located on the bottom surface of the support surface, and the lower rear baffle 15 is coplanar with the upper rear baffle 12.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] This type of defrosting cabinet, capable of achieving uniform defrosting, features a simple structure, ingenious design, and rational layout. Addressing the problems inherent in traditional defrosting cabinets, it employs a unique structure that optimizes the position and distribution of air outlets. The wire mesh supporting the defrosted items has also been redesigned to perfectly match the specially arranged air outlets, ensuring unobstructed flow of hot air within the cabinet. This allows for the even and rapid distribution of heat throughout the cabinet, achieving uniform heating and defrosting. It effectively improves defrosting efficiency while preventing uneven heating of the defrosted items, ensuring defrosting quality. Furthermore, its simple manufacturing process and low production cost make it a highly advantageous and widely applicable product with a promising market prospect. Attached Figure Description

[0017] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 4 The image shows a defrosting cabinet capable of achieving uniform defrosting, comprising a cabinet body 1 as a base, a cabinet door at the opening of the cabinet body 1, a top plate at the top of the interior of the cabinet body 1, and a back plate 2 at the rear. An air duct 3 is formed between the top plate and the back plate 2 and the cabinet body 1. The inlet of the air duct 3 is located on the top plate, and a fan 4 is installed at the inlet of the air duct 3. An evaporator 5 and a heater 6 are installed inside the air duct 3. Multiple rows of longitudinally spaced, equally spaced air outlets are provided on the back plate 2, each row consisting of multiple air outlets 7.
[0018] The inner wall of the cabinet 1 is provided with longitudinally distributed support columns 8, and multiple sets of support blocks 9 are provided on the support columns 8. The support blocks 9 support a grid frame.
[0019] The aforementioned space frame includes an outer frame 10, within which multiple equally spaced support ribs 11 are arranged. All the support ribs 11 together form a support surface. At the tail of the outer frame 10, an upper rear stop rib 12 is provided on the top surface of the support surface. Multiple sets of limiting stop rib pairs are also provided on the top surface of the support surface, with a spacing of H between adjacent limiting stop rib pairs. Each pair of limiting stop ribs consists of two limiting stop ribs 13. Side stop ribs 14 are provided on both sides of the outer frame 10, and the spacing between each side stop rib 14 and the nearest limiting stop rib 13 is also H.
[0020] The height of the multiple air outlet rows is matched one-to-one with the height of the multiple grid frames, and the same air outlet row includes multiple air outlet groups. The distance between adjacent air outlet groups is H, and each air outlet group consists of multiple air outlets 7 distributed at equal intervals. At the same time, the horizontal position of each air outlet group corresponds to the position of a pair of limiting baffles 13.
[0021] The outer frame 10 is also provided with a lower rear baffle 15 located on the bottom surface of the support surface, and the lower rear baffle 15 is coplanar with the upper rear baffle 12.
[0022] The working process of the defrosting cabinet that can achieve uniform defrosting according to this utility model embodiment is as follows: Place the items to be defrosted (taking bottled frozen juice as an example) on the wire rack, close the cabinet door, and start the fan 4. Under the action of the fan 4, the air enters the air duct 3 and flows from top to bottom along the air duct 3. During this process, the evaporator 5 does not work, the heater 6 works, and the air in contact with the heater 6 absorbs heat and becomes hot air, which is finally discharged from the air outlet 7 opened on the back panel 2 and returns to the interior of the cabinet 1.
[0023] Because the layout of the air outlet 7 on the back panel 2 matches the layout of the related structures on the wire mesh, when bottled items are placed on the wire mesh, the wire mesh is equipped with multiple sets of limiting rib pairs, and the spacing H between adjacent limiting rib pairs takes into account the width of the bottled items during the design. In other words, due to the existence of these limiting rib pairs, the placement position of the bottled items is limited, that is, they can only be placed in the gaps between adjacent limiting rib pairs. When a wire mesh is full of bottled items, these bottled items will be distributed in multiple columns on the wire mesh, with multiple items placed in each column. The width between adjacent columns is the spacing between two limiting ribs 13 in the same set of limiting rib pairs (this spacing is less than H).
[0024] The air outlet group on the back panel 2 is positioned exactly to correspond to the hot air channel formed between the multiple rows of bottled items. In other words, when hot air is blown out through the air outlet 7 in the air outlet group, it will pass directly through the hot air channel and disperse into various parts of the cabinet after hitting the cabinet door at the end of the hot air channel. This structure can ensure that the hot air can be blown out smoothly without obstruction and evenly distributed in various parts of the cabinet cavity, thereby achieving the effect of uniform heating and uniform defrosting.
[0025] When the item to be thawed is not a bottled item, such as a relatively large frozen item, the wire rack can be removed directly from the support block 9, flipped 180° up and down, and then put back in its original position. At this time, the bottom of the wire rack is facing up. Since there is no protruding mechanism on the bottom of the wire rack, large frozen items can be placed directly on the inverted wire rack.
