Description

Technical Field

[0001] The utility model relates to the field of baking room structures, in particular to a baking room with hot air circulation in double baking chambers. Background Art

[0002] In order to facilitate the placement of different products in the prior art, some manufacturers set up the interior of the baking room as a structure with two baking chambers inside and outside, so as to place different products in different baking chambers, and the baking method of the two baking chambers is mainly hot air baking. Specifically, a new baking room disclosed in application number 202010781558.3 ​​is provided with two baking chambers named the first baking chamber and the second baking chamber, and hot air baking is formed by blowing hot air inward. Hot air baking in this type of double baking chamber usually achieves hot air baking by blowing hot air into the two baking chambers respectively, which is more energy-consuming. Please refer to the attachment of the above-mentioned prior patent for details. Figure 2 The above-mentioned prior patent blows the hot air generated by heating outside the baking room into the first baking chamber 5 and the second baking chamber 6 through the first air supply pipe 7 and the second air supply pipe 8 respectively, and the hot air after blowing circulates in the first baking chamber 5 and the second baking chamber 6.

[0003] However, in the actual working process, in order to ensure the temperature of the hot air circulating in the first baking chamber 5 and the second baking chamber 6, it is necessary to continuously blow the hot air heated by the external heating device 2 of the baking room body 1 into the first baking chamber 5 and the second baking chamber 6. Otherwise, as time goes by, there is no heating measure in the first baking chamber 5 and the second baking chamber 6, and the hot air temperature cannot be maintained only by the wind direction circulation composed of the internal first negative pressure fan 9 and the second negative pressure fan 11. In other words, the above-mentioned prior patent is essentially a one-way air supply baking method that blows hot air from the outside of the baking room body 1 to the inside, and as the air is supplied to the first baking chamber 5 and the second baking chamber 6, the internal air pressure increases and the pressure needs to be relieved to release the hot air, resulting in heat being wasted, so it is impossible to achieve the real hot air circulation, and it is therefore more energy-consuming.

The opening and closing of the fresh air valve can connect and isolate the inside of the baking room 1 from the outside air through the fresh air pipe 41, that is, when the fresh air valve is opened, the air outside the baking room 1 can be replenished into the baking room 1, and fresh air can be replenished into the baking room 1 through the fresh air pipe 41 to eliminate the internal pressure of the baking room 1 and provide a positive pressure operating environment; and when the fresh air valve is closed, the baking room 1 can be sealed to prevent the hot air from leaking out during baking.

[0034] As attached Figure 2 and 4 As shown, heating groups 5 are arranged in both air ducts 103. Figure 5 and 6 The heating group 5 includes a heating tube rack 51 and a heating tube 52. The heating tube rack 51 is fixed to the side wall of the baking room 1. The heating tube rack 51 includes a vertical rod 511 and a connecting rod 512. A plurality of vertical rods 511 are vertically fixed in the air duct 103. Each vertical rod 511 and the side wall of the baking room 1 are connected and fixed by the connecting rod 512. The connection method can be fixed by screws. A plurality of heating tubes 52 are fixed from top to bottom between two adjacent vertical rods 511. The heating tubes 52 are fixed to the heating tube rack 51 by attaching Figures 6 to 8The mounting assembly 53 shown is fixed. The mounting assembly 53 includes a fixed ring 531, a movable ring 532, a conductive member, a screw shaft 534 and a butterfly nut 535. The fixed ring 531 and the movable ring 532 are both made of insulating materials, preferably insulating plastic. The inner rings of the fixed ring 531 and the movable ring 532 are both embedded with conductive members 533 of conductive materials, preferably copper members, and the conductive members 533 are preferably arc-shaped structures. A connecting plate 537 is provided at one end of the fixed ring 531, and a clearance opening 5301 penetrating from top to bottom is provided at the other end of the fixed ring 531. The connecting plate 537 is connected to the column through bolts 538 to fix one end of the fixed ring 531 to the column 511. One end of the movable ring 532 is connected to the fixed ring 531 through a connecting rod (not shown in the figure), and the two ends of the connecting rod are respectively pivoted to the fixed ring 531 and the movable ring 532. The pivoting structures in this embodiment can be connected by a pin, and the two pivoted parts can rotate with each other, that is, the fixed ring 531 and the movable ring 532 can be turned over by the connection of the connecting rod. In addition, the other end of the movable ring 532 is pivoted to one end of the screw shaft 534, and the butterfly nut 535 is screwed to the screw shaft 534.

[0035] When installing the heating tube 52, in two adjacent heating tubes 52 that need to be installed at the same height, the conductive ends of the two heating tubes 52 that are close to each other are placed on the conductive member 533 of the fixed ring 531, and then the movable ring 532 is rotated until the screw shaft 534 passes through the clearance opening 5301, and then the butterfly nut 535 is screwed to press against the fixed ring 531, so as to drive the movable ring 532 to press against the fixed ring 531, so that the conductive member 533 of the movable ring 532 is pressed against the conductive ends of the two heating tubes 52, thereby forming a conductive connection between the conductive ends of the two adjacent heating tubes 52.

[0036] In addition, one side of each row of heating tubes 52 is conductively connected to the same side of the upper row of heating tubes 52, and the other side is conductively connected to the other side of the lower row of heating tubes 52. The connection structure is that the fixing rings 531 fixed on both sides of the heating tube rack 51 are also provided with penetrating connection holes, and the conductive member 533 fixed to the fixing ring 531 is provided with a protruding conductive stud 536, and the conductive stud 536 is adapted to the screw connection nut after passing through the connection hole. The two ends of the conductive wire 54 are fixed with terminals 541. After the two terminals 541 are respectively sleeved on the conductive studs 536 of the upper and lower mounting components 53, the terminals 541 are pressed by the nuts to form a conductive connection between the upper and lower adjacent rows of heating tubes 52. Finally, each heating tube 52 in the heating group 5 forms a continuous S-shaped connection structure in series, so that each heating tube 52 in the heating group 5 can be energized to convert electrical energy into thermal energy, so that heat can be released in the air duct 103 to heat the air in the air duct 103.

[0037] In the above installation structure of the heating tube 52, when one of the heating tubes 52 is damaged, the damaged heating tube 52 can be taken out by flipping up the movable rings 532 of the installation components 53 at both ends of the heating tube 52, and then a new heating tube 52 is put in. Then, the movable rings 532 of the two installation components 53 are flipped down and locked by butterfly nuts 535. The replacement of the heating tube 52 can be completed without re-disassembling and wiring, so it is very convenient. In addition, in the connection structure of the installation component, the two heating tubes 52 are electrically connected by connecting the conductive member 533, and the fixed ring 531 and the movable ring 532 are both made of insulating materials, so that the current can be prevented from leaking to the heating tube rack 51.

[0038] Continue to refer to the attached Figure 2 and 4 , the two air ducts 103 are both provided with fan groups 6, and the fan groups 6 in the two air ducts 103 are respectively provided on one side of the first baking chamber 101 and one side of the second baking chamber 102. Fig. 9 The fan group 6 includes a fan frame 61 and a circulating fan 62. The fan frame 61 is placed in the air duct 103, and the fan frame 61 is located between the heating group 5 and the isolation net 3. The fan frame 61 fixes a plurality of circulating fans 62, and each circulating fan 62 supplies air to the first baking chamber 101 and the second baking chamber 102. Specifically, the circulating fan 62 corresponding to the first baking chamber 101 blows the hot air in the air duct 103 into the first baking chamber 101 to form hot air, and the circulating fan 62 corresponding to the second baking chamber 102 blows the hot air in the air duct 103 into the second baking chamber 102 to form air supply. This air supply method can form an air supply method in which hot air circulates in the first baking chamber 101 and the second baking chamber 102, so as to attach Figure 4 For example, the fan unit 6 located on the left side of the upper air duct 103 transports the hot air in the upper air duct 103 to the first baking chamber 101, and the hot air flows through the first baking chamber 101 to the lower air duct 103. At the same time, the fan unit 6 located on the right side of the lower air duct 103 transports the hot air in the lower air duct 103 to the second baking chamber 102, and the hot air flows back to the upper air duct 103 through the second baking chamber 102, thereby forming a circulating air supply method in which the hot air circulates through the two air ducts 103 in the first baking chamber 101 and the second baking chamber 102. Compared with the unidirectional air supply method, this method can recycle the hot air passing through the first baking chamber 101 and the second baking chamber 102, thereby avoiding the loss of heat energy and saving energy consumption for product baking.

[0039] In summary, the utility model uses an isolation net 3 to space the two sides of the interior of the baking room 1 to form an air duct 103, and uses a partition wall 12 to separate the space between the two isolation nets 3 to form an independent first baking chamber 101 and a second baking chamber 102. In this structure, the two air ducts 103 are connected to the first baking chamber 101 and the second baking chamber 102. During operation, the circulating fan 62 corresponding to the first baking chamber 101 blows the hot air in the air duct 103 on one side into the first baking chamber 101 and circulates it into the air duct 103 on the other side. The circulating fan 62 corresponding to the second baking chamber 102 blows the hot air in the air duct 103 on the other side into the second baking chamber 102 and blows it into the air duct 103 on one side. Through this air supply method, an air supply method in which the hot air circulates in the first baking chamber 101, the second baking chamber 102 and the air ducts 103 on both sides can be formed, so that the hot air passing through the first baking chamber 101 and the second baking chamber 102 can be recycled, thereby avoiding the loss of heat energy, thereby saving energy consumption for baking products, and the circulation of hot air during the baking process can also make the baked products heated more evenly, which is beneficial to improving the quality of the baked products.

[0040] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
