[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0025] See also Figures 1 to 3 The figure shows a tunnel oven that is convenient for uniform steaming, including: a tunnel oven body 10, a steam component, the steam component is used to uniformly transport steam to the interior of the tunnel oven body 10, and the steam component is horizontally arranged at the lower interior of the tunnel oven body 10; a spray component, the spray component is used to uniformly spray a layer of water mist on the surface of the food, and the spray component is horizontally arranged above the interior of the tunnel oven body 10; a guide component, the guide component is used to guide the steam condensate beads on the top of the tunnel oven body 10 to the outer top of the spray component, and the guide component is arranged above the spray component.

[0026] The utility model is provided with a spray assembly on the inner upper part of the tunnel furnace body 10, which sprays water mist above the food to be steamed, so that the moisture content of the food is uniform during steaming, and the steamed food is soft, fragrant and delicious; the inner top of the tunnel furnace body 10 is provided with a diversion assembly, which is convenient for diverting water droplets condensed on the inner top surface of the tunnel furnace body 10 to prevent them from dripping onto the food and soaking the top of the food, thereby preventing water vapor from affecting the taste of the food during food preparation and reducing the qualified rate of the finished product.

[0027] In this preferred embodiment, combined with Figure 2 The steam component includes a steam generator, a steam control valve, a steam main pipe 21, several steam branch pipes 22, and several steam pipes 23, which are connected in sequence through a steam pipe 23. The steam control valve is used to open or close the channel of the steam branch pipe 22. Several steam holes 24 are set through the top of each steam pipe 23.

[0028] Specifically, inside the tunnel furnace body 10, directly above the steam pipe 23, brackets and trays are sequentially arranged, and food to be steamed is neatly placed in the trays; when the steam control valve is opened, the steam generated by the steam generator is sequentially transmitted to the steam main pipe 21 and several steam branch pipes 22, and is output to the interior of the tunnel furnace body 10 through several steam holes 24.

[0029] In this preferred embodiment, combined with Figure 3 The spray assembly includes a second steam branch pipe 22, a liquid storage tank, an air compressor, a spray control valve, a spray main pipe 31, a plurality of spray branch pipes 32, and a plurality of nozzles 33, which are connected in sequence through the spray pipe. The second steam branch pipe 22 is connected to the steam main pipe 21 of the steam assembly. The air compressor is used to reduce the volume and increase the pressure of the mixture of steam and liquid in the spray pipe. The spray control valve is used to open or close the spray action of the nozzle 33.

[0030] Specifically, the spray assembly is connected to the steam main pipe 21 of the steam assembly through the second steam branch pipe 22, the liquid in the liquid storage tank is mixed with the steam introduced from the second steam branch pipe 22, and the air compressor compresses the air to form fine droplets or mist.

[0031] As the steam component is arranged at the bottom of the tunnel oven, and under the action of gravity, the steam density above the interior of the tunnel oven body 10 is lower than the steam density below the interior; the spray released by the multiple nozzles 33 of the spray component can not only compensate for the above, but also make the steam inside the tunnel oven body 10 more uniform, so as to achieve uniform steaming of multiple foods; the spray component can also spread a layer of mist on the outer surface of the food to prevent the surface of the food from being hard during steaming, and ensure that the food is soft, fragrant and delicious.

[0032] In this preferred embodiment, combined with Figure 3 The guide assembly includes several guide plates 41 and a collecting trough 43. The several guide plates 41 are neatly arranged on the top plate 11 of the tunnel furnace body 10. The two ends of the collecting trough 43 are installed on the inner wall of the tunnel furnace body 10. The collecting trough 43 is located directly below the several guide plates 41.

[0033] Furthermore, both ends of the spray branch pipe 32 are respectively mounted on the inner wall of the tunnel furnace body 10 , and the collecting trough 43 is provided on the top outer surface of a plurality of the spray branch pipes 32 .

[0034] Specifically, the longitudinal section of the collecting tank 43 is in the shape of a U, which is convenient for collecting steam droplets to prevent the surface of food from getting wet; the heat in the several spray branches 32 can be transferred to the collecting tank 43 through a layer, and the liquid in the collecting tank 43 is evaporated again as a heat source and recycled.

[0035] Furthermore, the top of the tunnel furnace body 10 is a pair of top plates 11 symmetrically arranged with each other, and the overall longitudinal section of the two top plates 11 is in an inverted V shape.

[0036] Furthermore, the longitudinal section of the guide plate 41 is L-shaped, and a condensing plate 42 for condensing steam droplets is provided at the end of the guide plate 41 .

[0037] The top plate 11 for mounting the guide plate 41 is tilted to facilitate the guide plate 41 to guide the flow; the condensation plate 42 can further promote the condensation of steam into water droplets.

[0038] Preferably, an exhaust component is longitudinally arranged at the top of the left and right ends of the tunnel oven body 10, and the exhaust component is an exhaust fan 12; after the tunnel oven cooks food, the exhaust fan 12 is started to extract the steam inside the tunnel oven body 10 to prevent scalding of users.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
