Description

Technical Field

[0001] The invention relates to the fields of freezing, refrigeration and thawing, in particular to a thawing cabinet with intelligent temperature control and uniform air outlet structure. Background Art

[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 when it is working to all parts of the cabinet, so that the items placed in the cabinet can be cooled down and frozen. In some cases, it is necessary to thaw the frozen items quickly, so a thawing cabinet is used. The structure and principle of the thawing cabinet are similar to those of a freezer. A fan is used to blow the heat generated by the heating device when it is working to all parts of the cabinet, so that the items placed in the cabinet can be quickly heated up until they are thawed.

[0003] However, traditional thawing cabinets expose many problems during use: First, different ingredients require different thawing times due to their different specific heat capacities. Traditional thawing cabinets do not consider the impact of specific heat capacity on thawing time. Items with different specific heat capacities are often placed in the inner cavity of the thawing cabinet. Under the same thawing time, items with different specific heat capacities take different times to completely thaw. It is necessary to rely on the experience of the staff to judge which items have been thawed. When the operator is inexperienced, some items may take too long to thaw during one thawing process, affecting the taste and even quality, while some items may not be completely thawed. In addition, the air outlets on the back panel of a traditional freezer are distributed in an array to ensure that the hot air can be evenly distributed in the inner cavity of the cabinet. However, in actual work, a large number of items to be thawed are stacked on the racks. For the sake of work efficiency, operators often place a large number of thawed items on the racks at one time, and there are either no gaps (or very small gaps) between these items, or the air outlets are directly blocked, which will block the flow of hot air or change the flow trajectory of the hot air. This will cause the items near the air outlet to be thawed earlier due to the absorption of more heat, but other locations in the freezer cannot flow hot air due to the obstruction of the items, which prolongs the thawing time of the items in other locations and causes uneven thawing.

[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0005] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes a thawing cabinet with a simple structure, ingenious design, and reasonable layout. The cabinet can automatically determine the type and quantity of items to be thawed in the cabinet and perform adaptive thawing control according to the above parameters. At the same time, the cabinet can ensure that hot air can be evenly distributed in the cabinet to obtain a better thawing effect.

[0006] The technical solution of the present invention is: a thawing cabinet with intelligent temperature control and uniform air outlet structure, comprising a cabinet body 1, characterized in that the interior of the cabinet body 1 is divided into two chambers, namely a freezing cabinet chamber and a thawing cabinet chamber 2, and the cabinet body 1 is provided with cabinet doors respectively matching the freezing cabinet chamber and the thawing cabinet chamber 2, The top of the thawing cabinet cavity 2 is provided with a top plate, and the rear is provided with a back plate 3, and an air duct 4 is formed between the top plate, the back plate 3 and the cabinet body 1, and the entrance of the air duct 4 is opened on the top plate, and a fan 5 is also provided at the entrance of the air duct 4.

[0007] The grid comprises an outer frame 12, in which a plurality of support ribs 13 are arranged at equal intervals, and all the support ribs 13 together form a support surface, and an upper rear retaining rib 14 located on the top surface of the support surface is arranged at the tail of the outer frame 12, and a plurality of groups of limit retaining rib pairs are arranged on the top surface of the support surface, and the spacing between adjacent limit retaining rib pairs is H, and each pair of limit retaining rib pairs is composed of two limit retaining ribs 15, and side retaining ribs 16 are respectively arranged on both sides of the outer frame 12, and the spacing between the side retaining rib 16 and the nearest limit retaining rib 15 is also H, The heights of the multiple air outlet rows are matched one by one with the heights of the multiple grids, and the same air outlet row includes multiple air outlet groups, the spacing between the center lines of adjacent air outlet groups is H, and each air outlet group is composed of multiple air outlets 8 distributed at equal intervals, and the horizontal position of each air outlet group corresponds to the position of a pair of limiting ribs 15.

[0023] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 7 As shown: a thawing cabinet with intelligent temperature control and uniform air outlet structure, comprising a cabinet body 1 as a basis, the interior of the cabinet body 1 is divided into two chambers, namely a freezing cabinet chamber and a thawing cabinet chamber 2, the cabinet body 1 is provided with cabinet doors respectively matching the freezing cabinet chamber and the thawing cabinet chamber 2, wherein the internal structure of the freezing cabinet chamber is the same or essentially the same as that of a traditional freezing cabinet, both of which are generated by a refrigeration unit, and the cold energy is blown to various places inside the freezing cabinet chamber by a fan, thereby realizing the freezing operation of the items; The top of the thawing cabinet cavity 2 is provided with a top plate, and the rear is provided with a back plate 3, and an air duct 4 is formed between the top plate, the back plate 3 and the cabinet body 1, and the entrance of the air duct 4 is opened on the top plate, and a fan 5 is also provided at the entrance of the air duct 4. An evaporator 6 and a heater 7 are provided in the air duct 4, and multiple rows of air outlets are arranged on the back plate 3, and each air outlet row is composed of multiple air outlets 8. The four corners of the inner wall of the thawing cabinet cavity 2 are provided with longitudinally distributed support columns 9, and multiple groups of support blocks 10 are provided on the support columns 9. The same group of support blocks 10 jointly support a grid. The cabinet 1 is also provided with an object identification mechanism and a control touch integrated machine 11. The fan 5, evaporator 6, heater 7, object identification mechanism and control touch all-in-one machine 11 are all connected to a control system disposed in the cabinet 1, and a wireless communication module is disposed in the control system.

[0024] The grid comprises an outer frame 12, in which a plurality of support ribs 13 are arranged at equal intervals, and all the support ribs 13 together form a support surface, and an upper rear retaining rib 14 located on the top surface of the support surface is arranged at the tail of the outer frame 12, and a plurality of groups of limit retaining rib pairs are arranged on the top surface of the support surface, and the spacing between adjacent limit retaining rib pairs is H, and each pair of limit retaining rib pairs is composed of two limit retaining ribs 15, and side retaining ribs 16 are respectively arranged on both sides of the outer frame 12, and the spacing between the side retaining rib 16 and the nearest limit retaining rib 15 is also H, The heights of the multiple air outlet rows are matched one by one with the heights of the multiple grids, and the same air outlet row includes multiple air outlet groups, the spacing between the center lines of adjacent air outlet groups is H, and each air outlet group is composed of multiple air outlets 8 distributed at equal intervals, and the horizontal position of each air outlet group corresponds to the position of a pair of limiting ribs 15.

[0025] The tail of the outer frame 12 is also provided with a lower rear baffle 17 located at the bottom of the support surface, and the lower rear baffle 17 is coplanar with the upper rear baffle 14 .

[0026] The object identification mechanism is a camera 18 disposed on the top plate.

[0027] The article identification mechanism is a barcode scanner 19 , and the barcode scanner 19 is placed on a barcode scanner frame 20 arranged outside the cabinet 1 .

[0028] The article identification mechanism is an RFID reader / writer 21 disposed on the door of the freezer cavity.

[0029] The heater 7 is a PTC heater.

[0030] The working process of the thawing cabinet with intelligent temperature control and uniform air outlet structure of the embodiment of the present invention is as follows: when food needs to be frozen and stored (taking bottled juice as an example), it is placed in the freezer cavity and the cabinet door is closed. After a period of time, the juice in the bottled juice is frozen for long-term storage; When juice is needed, the frozen bottled juice needs to be put into the thawing cabinet cavity 2 for thawing. The specific operation process is as follows: when each item to be thawed is put into the thawing cabinet cavity 2, the item is identified by the item identification mechanism. Each time an item is identified, the control system will record one item. When all the items are placed, the control system grasps the type and quantity of the items placed in the thawing cabinet cavity 2 in the current state, and calculates the thawing time that matches the type and quantity of the current items according to the above parameters through its built-in program, and controls the actions of each actuator according to the time. The fan 5 is started. Under the action of the fan 5, air enters the air duct 4 and flows from top to bottom along the air duct 4. During this process, the evaporator 6 does not work, and the heater 7 works. The air released from the heater 7 absorbs heat and becomes hot air, which is finally discharged from the air outlet 8 opened on the back plate 3 and returns to the interior of the cabinet 1. Since the layout of the air outlets 8 on the back plate 3 matches the layout of the related structures on the grid, that is, when the bottled items are placed on the grid, since there are multiple sets of limit rib pairs on the grid, and the spacing H between adjacent limit rib pairs is designed with reference to the width of the bottled items, that is, due to the existence of these limit rib pairs, the placement of the bottled items is limited, that is, they can only be placed in the gaps between adjacent limit rib pairs. When a grid is full of bottled items, these bottled items will be distributed in multiple rows on the grid, and each row has multiple bottles, and the width between adjacent rows is the spacing between two limit ribs 15 in the same set of limit rib pairs (the spacing is smaller than H); The position of the air outlet group on the back plate 3 just corresponds to the hot air channel formed between the multiple rows of bottled items. That is to say, when the hot air is blown out through the air outlet 8 in the air outlet group, it will directly pass through the hot air channel and disperse to various places in 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 places in the cabinet cavity, thereby achieving the effect of uniform heating and uniform thawing. When the items to be thawed are not bottled items, such as frozen items of relatively large overall size, the rack can be directly removed from the support block 10, flipped upside down 180° and put back in place, with the bottom end of the rack facing upward. Since there is no structure protruding from the plane on the bottom end of the rack, larger frozen items can be placed directly on the inverted rack.

[0031] When the object identification mechanism is a camera 18, the operator does not need to perform additional operations, and only needs to place the object to be thawed on the rack. The camera 18 will take an image of the thawed object and use the image recognition software built into the control system to identify it to determine the type and specification of the object; When the object identification mechanism is a barcode scanner 19, the operator needs to use the barcode scanner 19 to scan the identification code attached to the outer packaging of the object to be thawed before placing the object into the thawing cabinet cavity 2. After scanning, the control system knows the type and quantity of the object placed in the thawing cabinet cavity 2; When the item identification mechanism is an RFID reader / writer 21 arranged on the cabinet door of the freezer cavity, the operator needs to place the items to be thawed close to the RFID reader / writer 21 before placing them into the thawing cabinet cavity 2. The RFID reader / writer 21 will automatically read the RFID tag pre-attached to the outer packaging of the items to be thawed and send a signal to the control system, so that the control system knows the type and quantity of the items placed in the thawing cabinet cavity 2.
