[0032] Please refer to Figure 2 and refer to Figure 1 , Figure 2For the use state reference figure of the oven steam condensing device, the oven steam condensing device provided by the application is used for the steam generated during the baking of the oven, so the oven steam condensing device can be used in cooperation with the oven 10, and in specific application, the oven 10 can be placed on the support 20, the first cover body 1 is fixed on the oven through bolts or other fixing members, and the first pipeline 2 is connected with the exhaust pipeline of the oven 10, and the tail end of the second pipeline 3 is connected with the floor drain or the container for containing water, and after installation, the oven steam condensing device can be used. After the oven 10 generates steam during baking, the steam enters the first cavity 11 through the first pipeline 2, and after the steam enters the first cavity 11, it starts to diffuse into the second cavity 12, and during the diffusion process, the steam flows in contact with the cooling assembly 4 and is quickly liquefied, and the liquid generated by the liquefaction flows out from the second pipeline 3, and other gases are discharged from the exhaust hole 15.

[0033] The first cover body 1 is fixed on the oven 10 through simple fixing tools, and the first pipeline 2 is connected with the exhaust pipeline of the oven 10, and the second pipeline 3 is connected with the floor drain or other water storage containers, so that the steam can be liquefied by the condensing assembly 4 arranged in the first cover body 1, and the gas is discharged from the exhaust hole 15 in the first cover body 1. In this way, without installing an exhaust pipeline in the kitchen or baking place, the problems of steam scalding and environmental pollution and sanitation can be solved, and the cost problem of installing a ventilation pipeline is solved.

[0034] Further, please refer to Figure 1 , the oven steam condensing device further comprises an air suction device 5. The first cover body 1 further has a third cavity 13 and a fourth cavity 14, the first cavity 11, the second cavity 12 and the third cavity 13 are arranged in the first cover body 1 in sequence, the third cavity 13 is connected with the second cavity 12; the fourth cavity 14 is connected with the third cavity 13 and the exhaust hole 15 respectively; and the air suction device 5 is installed in the fourth cavity 14.

[0035] In specific application, please refer to Figure 2 , the air suction device 5 is connected to the power supply, after the air suction device 5 operates, the air suction device 5 discharges the gas in the fourth cavity 14 to the atmosphere outside the first cover body 1, so that the pressure in the fourth cavity 14 is less than the pressure in the third cavity 13, and there is a pressure difference between the fourth cavity 14 and the third cavity in the first cover body 1, so that the steam entering the first cavity 11 from the first pipeline 2 flows through the second cavity 12, then through the third cavity 13, and then enters the fourth cavity 14. When the steam flows through the second cavity 12, it is in contact with the condensing assembly in the second cavity 12 and is liquefied, and the water droplets fall into the bottom of the second cavity 12 and then flow into the second pipeline 3 and are discharged to the outside of the first cover body 1 through the second pipeline 3.

[0036] In this way, through the air suction of the air suction device 5, the steam flows through the first cavity 11, the second cavity 12, the third cavity 13 and the fourth cavity 14 in sequence, so that the gas discharge capacity of the oven steam condensing device is larger and the condensing efficiency is higher.

[0037] Further, refer to Figure 3 . Figure 3 is a sectional view of the oven steam condensing device, the cooling assembly 4 comprises a plurality of aluminum tubes 41 fixed in the second cavity 12.

[0038] In specific application, after the steam enters the second cavity 12, it flows through the outer surface of the plurality of aluminum tubes 41 in turn, the steam contacts the outer surface of the aluminum tubes 41, the aluminum tubes 41 absorb heat from the steam and liquefy it, achieving the cooling effect.

[0039] Further, refer to Figure 4 and Figure 5 , and refer to Figure 3 , Figure 4 is a perspective view of the oven steam condensing device, Figure 5 is a use state reference view of the oven steam condensing device from another perspective. The oven steam condensing device further comprises a second cover body 6 connected with the first cover body 1, the second cover body 6 is concave inward from the bottom to form a smoke collecting cavity 61, one side of the second cover body 6 connected with the first cover body 1 is provided with a plurality of air inlet holes 62; the two ends of the aluminum tubes 41 penetrate through the two sides of the second cavity 12 and communicate the second cover body 6 and the fourth cavity 14.

[0040] In specific application, after the baking of the oven 10 is completed, a part of steam will be generated when the oven door 30 is opened. For this part of steam, the air suction device 5 is used to suck air, so that the smoke collecting cavity 61 of the second cover body 6 faces the oven door 30 to suck air, the steam generated when the oven door 30 is opened is sucked into the smoke collecting cavity 61, and then enters the tubes of the aluminum tubes 41 from the two ends of the aluminum tubes 41 through the air inlet holes 62 provided on the second cover body 6. When flowing through the inner wall of the hollow aluminum tubes 41, the steam is liquefied.

[0041] In this way, the second cover body 6 is provided, which can absorb the steam generated in an instant when the oven door 30 is opened, achieving the effect of all-round condensation, and further avoiding the scalding of the person operating the oven.

[0042] Further, refer to Figure 6 , Figure 6 is a perspective view of the oven steam condensing device from another perspective, the oven steam condensing device further comprises a third pipeline 7 provided on the first cover body 1, the third pipeline 7 respectively communicates with the inside of the fourth cavity 14 and the outside of the first cover body 1.

[0043] When the oven steam condensing device condenses the steam overflowed from the oven door 30, a small amount of water droplets generated in the aluminum pipe 41 can be discharged. In practical applications, the third pipe 7 is connected to a floor drain or other water storage container. The steam is liquefied in the pipe of the aluminum pipe 41 and generates water droplets. The suction device 5 sucks the water droplets into the fourth cavity 14. The water in the fourth cavity 14 flows out of the first cover body 1 through the third pipe 7.

[0044] Further, please refer to Figure 2 and 3 The second cavity 12 has a first wall surface 121 and a second wall surface 122. The height of the aluminum pipe 41 is less than the height between the first wall surface 121 and the second wall surface 122. The plurality of aluminum pipes 41 are divided into two groups. One group of aluminum pipes 41 is arranged near the first wall surface 121, and the other group of aluminum pipes 41 is arranged near the second wall surface 122. The two groups of aluminum pipes 41 are arranged in a cross pattern, and the plurality of aluminum pipes 41 are arranged in parallel.

[0045] In this way, only one passage is formed in the second cavity 12. After the steam enters the second cavity 12, it successively passes through the outer surface of each aluminum pipe 41. When the steam passes through the outer surface of the first aluminum pipe 41, it flows from above the aluminum pipe 41, i.e., from the side near the first wall surface 121. When the steam passes through the outer surface of the second aluminum pipe 41, it flows from the side near the second wall surface 122. This process is repeated until the steam flows out of the second cavity 12, thereby achieving a better cooling effect of the cooling assembly 4.

[0046] It is worth noting that the steam that escapes from the oven door 30 enters the pipe of the aluminum pipe 41 through the second cover body 6 and condenses in the aluminum pipe 41. The steam that enters the second cavity 12 from the first pipe 2 successively flows through the outer surface of each aluminum pipe 41, and the steam condenses in the second cavity 12.

[0047] Further, please refer to Figure 7 and refer to Figure 3 , Figure 7As a structural schematic diagram of the first wall surface and the second wall surface, the second wall surface 122 comprises a first bottom wall 1221 and a second bottom wall 1222, the first bottom wall 1221 and the second bottom wall 1222 are sequentially connected along the arrangement direction of the plurality of aluminum pipes 41; the first bottom wall 1221 has a first end 12211 and a second end 12212, the first end 12211 is away from the second bottom wall 1222, the second end 12212 is connected with the second bottom wall 1222, and the distance between the first bottom wall 1221 and the first wall surface 121 gradually increases in the direction from the first end 12211 to the second end 12212; the second bottom wall 1222 has a third end 12221 and a fourth end 12222, the third end 12221 is away from the first bottom wall 1221, the fourth end 12222 is connected with the second end 12212, and the distance between the second bottom wall 1222 and the first wall surface 121 gradually increases in the direction from the third end 12221 to the fourth end 12222; the second pipeline 3 is located at the connection position of the second end 12212 and the fourth end 12222.

[0048] Thus, when the steam in the second cavity 12 is liquefied, the generated liquid water falls on the second wall surface 122, the water on the first bottom wall 1221 is affected by gravity and flows from the first end 12211 to the second end 12212, and the water on the second bottom wall 1222 is also affected by gravity and flows from the third end 12221 to the fourth end 12222, the water condensed in the second cavity 12 flows into the connection position of the second end 12212 and the fourth end 12222, that is, the lowest position of the second wall surface 122, and then flows out of the second cavity 12 through the drain pipe 3, which can effectively avoid water accumulation in the second cavity 12.

[0049] Further, please refer to Figure 1 , the air suction device 5 comprises a plurality of air suction fans 51, and the plurality of air suction fans 51 are all installed in the fourth cavity 14.

[0050] Thus, the air suction effect of the oven steam condensation device is better through the air suction effect of the plurality of air suction fans 51.

[0051] Further, the first cover body 1 has a connecting plate 16 located between the second cavity 12 and the third cavity 13, the connecting plate 16 is connected with the first wall surface 121 and the second wall surface 122 respectively, and the connecting plate 16 has a plurality of air holes 161, which are communicated with the second cavity 12 and the third cavity 13.

[0052] Thus, the connecting plate 16 is arranged between the second cavity 12 and the third cavity 13, the second cavity 12 and the third cavity 13 are separated by the connecting plate 16, the gas flows through the air holes 161, and the liquid water in the second cavity 12 can be prevented from being sucked into the third cavity 13, thereby avoiding water accumulation in the third cavity 13.

[0053] Further, please refer toFigure 7 The first pipe 2, the second pipe 3 and the third pipe 7 are located at the same side of the first cover 1.

[0054] Thus, after the second pipe 2 is connected with the steam exhaust pipe of the oven 10, since the steam exhaust pipe of the oven 10 is mostly located at the side opposite to the oven door 30, the second pipe 3 and the third pipe 7 are just located at the side opposite to the oven door 30, and the second pipe 3 and the third pipe 7 are connected with the floor drain or the water storage container, which will not affect the appearance of the kitchen.

[0055] In summary, the first cover is fixed on the oven by simple fixing tools, and then the first pipe is connected with the steam exhaust pipe of the oven, and the second pipe is connected with the floor drain or other water storage container. The steam can be liquefied by the condensing device arranged in the first cover, and the gas is discharged from the first cover through the exhaust hole. In this way, the problem of steam scalding and environmental pollution can be solved without installing exhaust pipes in the kitchen or baking place, and the cost problem of installing ventilation pipes is solved.

[0056] The above is only an embodiment of the present application and is not intended to limit the present application. The present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
