[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1-3 The utility model provides the following technical solution: a steam tunnel furnace, comprising a support 1 and a furnace body 2 arranged on the support 1, the furnace body 2 comprising:

[0032] The steam pipe 21 is arranged in the middle of the support 1;

[0033] A furnace cover 22 is provided on the support 1 and is located above the steam pipe 21;

[0034] The exhaust mechanism 23 is disposed on the support 1 and located at both ends of the furnace cover 22 . The exhaust mechanism 23 includes a steam collecting cover 231 and a negative pressure fan 232 on the top of the steam collecting cover 231 .

[0035] As an optional implementation scheme of the present invention, when steaming, the steam in the steam pipe 21 enters the furnace hood 22, that is, the tunnel furnace, through the hole on the steam pipe 21 to steam and cook the food in the steaming tray placed on the bracket 1. After the steam flows through the steaming tray, it is blocked by the furnace hood 22 and cannot flow directly to the outside. When the exhaust mechanism 23 is in operation, the steam is directly extracted to maintain the normal air pressure in the tunnel furnace and prevent the steam from flowing out from both ends of the bracket 1 to the outside. Therefore, whether it is during the entire steaming process or in the process of putting in or taking out the steaming tray, the steam will not flow directly to the surrounding environment of the tunnel furnace, avoiding the high-temperature steam from affecting the temperature and humidity of the kitchen environment. The exhaust method can prevent the accumulation of a large amount of steam, greatly reducing the probability of leakage of the furnace hood 22, thereby preventing the pollution of the environment caused by high-temperature steam. Compared with the current tunnel furnace that only uses a chimney, it is more suitable for use in modern commercial restaurants with a large number of people.

[0036] Through the above structure, the steam after steaming the food during the cooking process can be discharged by suction, eliminating the risk of high-temperature steam flowing into the kitchen environment and causing pollution.

[0037] like Figures 1-2 As shown, the furnace hood 22 includes:

[0038] Guard plates 221, two guard plates 221 are respectively arranged at the front and rear sides of the bracket 1;

[0039] Support frame 223, two arched support frames 223 are respectively arranged at both ends of the guard plate 221, and the middle parts of the tops of the two support frames 223 are connected by a top beam 225;

[0040] Maintenance door 222, two maintenance doors 222 are rotatably connected to the top beam 225 through spring hinges 227, and a sealing strip 224 is arranged on the lower surface of the maintenance door 222;

[0041] A lock 226 for locking the maintenance door 222 is further arranged on the outer surface of the guard plate 221.

[0042] As an optional implementation of the present utility model, when it is necessary to maintain the steam pipe 21, the lock 226 can be used to release the lock on the maintenance door 222, so that the maintenance door 222 can be turned upwards to open the furnace cover 22. The spring hinge 227 enables the maintenance door 222 to automatically turn upwards after unlocking and keeps the maintenance door 222 in an open state during maintenance. The operator can then check the steam pipe 21 for problems such as blockage and damage; after the maintenance is completed, the maintenance door 222 is pulled down to cover the guard plate 221, and the sealing strip 224 on the sealing door eliminates the gap between the sealing door and the guard plate 221 and the support frame 223, ensuring that steam will not escape at the maintenance door 222 during the steaming process and affecting the kitchen environment.

[0043] The lock 226 is a relatively mature existing technology in the market. Specifically, it can include common locks 226 on freight carriages and safes. Of course, the present technical solution is not limited to this, and any detachable fixation between the maintenance door 222 and the guard plate 221 can be included in the concept of the present technical solution.

[0044] Such as Figure 3 shown, it further includes a conveying device 3. The conveying device 3 is arranged on the bracket 1 and includes a conveyor belt rotatably connected to both ends of the bracket 1 and a driving unit 31 for driving the conveyor belt to rotate. There is a conveying gap 233 for the steam tray to enter and exit between the bottom of the air extraction mechanism 23 and the bracket 1.

[0045] As an optional implementation of the present utility model, when it is necessary to add a steam tray to the tunnel furnace, place the steam tray at one end of the conveyor belt. After starting the driving unit 31, the conveyor belt starts to operate, and the steam tray is conveyed into the tunnel furnace through the conveying gap 233 and is located above the steam pipe 21. After stopping the driving unit 31, steaming can be carried out; after steaming is completed, start the driving unit 31 again, and the conveyor belt can output the steam tray from the conveying gap 233 at the other end.

[0046] Among them, the driving unit 31 can adopt a motor.

[0047] Such as Figure 3As shown in the figure, a water guide plate 11 is provided on the bracket 1 and at the bottom of the steam pipe 21, and a water outlet hole 12 is provided at the bottom of the water guide plate 11.

[0048] As an optional embodiment of the present utility model, during the steaming process, steam will inevitably condense into water droplets and adhere to the furnace hood 22. Some of the water droplets may drip onto the water guide plate 11 and can be discharged from the water outlet hole 12, avoiding the long-term accumulation of water in the furnace and causing corrosion inside this tunnel furnace, or affecting the quality of the food during the steaming process.

[0049] The working principle and usage process of the present utility model: Before steaming, place the steaming tray at one end of the conveyor belt. After starting the driving unit 31, the conveyor belt starts to run, and the steaming tray is conveyed from the conveying gap 233 into the tunnel furnace and located above the steam pipe 21. After stopping the driving unit 31, steaming can be carried out.

[0050] During steaming, the steam in the steam pipe 21 enters the furnace hood 22, that is, inside this tunnel furnace, and steams the food in the steaming tray placed on the bracket 1. After the steam flows through the steaming tray, it is blocked by the furnace hood 22 and cannot directly flow to the outside. When the air extraction mechanism 23 operates, it directly extracts the steam to maintain the normal air pressure inside the tunnel furnace, preventing the steam from flowing out from both ends of the bracket 1 to the outside. This ensures that during the entire steaming process and when putting in or taking out the steaming tray, the steam will not directly flow into the surrounding environment of this tunnel furnace, avoiding the influence of high-temperature steam on the kitchen environment in terms of temperature and humidity. Moreover, the air extraction method can prevent a large amount of steam from accumulating, significantly reducing the probability of leakage of the furnace hood 22. Therefore, it can prevent the pollution of the environment caused by high-temperature steam.

[0051] After steaming is completed, start the driving unit 31 again, and the conveyor belt can output the steaming tray from the conveying gap 233 at the other end, and the operator can take it away.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
