The steam exhaust box used to connect the steam exhaust port is installed on the stove panel, and then the steam is discharged to the back of the cabinet, and then removed by the range hood above. This exhaust method will affect the combustion conditions of the stove working process and the product experience because the steam generated by the steam oven during the steaming and baking process is in a high-temperature and high-pressure state. Therefore, there is an urgent need for a measure that can reduce the total amount of steam discharged from the steam oven, reduce the steam pressure and temperature, so as to improve and reduce the impact of the high-temperature and high-pressure steam on the working process of the stove, improve the combustion of integrated cooking products, increase steam condensation, reduce steam emissions, reduce the adhesion of condensed water to the product surface, reduce the frequency of user scrubbing, and keep the product clean.

The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.
[0033] The first aspect of the utility model provides an exhaust box for condensing and discharging steam in a steam oven; the exhaust box comprises: an upper cover 2, a steam condensation baffle 4 and a lower cover 5; the lower cover 5 is provided with an air inlet, the upper cover 2 is provided with an air outlet, a condensation chamber is formed between the upper cover 2 and the lower cover 5, an independent steam condensation baffle 4 is provided in the condensation chamber, and a plurality of first steam exhaust holes 12 are provided on the steam condensation baffle 4; the first steam exhaust holes 12 have a guide plate for guiding the steam to flow toward the air outlet.
[0034] As described in the exhaust box of the first aspect of the utility model, the steam condensation baffle 4 is clamped and fixed between the upper cover 2 and the lower cover 5; the outer surface of the guide plate for guiding the steam to flow toward the outlet has a protrusion, and the protrusion constitutes the hole wall of the first steam exhaust hole 12. The shape of the guide plate is: an outer convex arc surface extending upward from the plane of the steam condensation baffle 4;
[0035] The upper cover 2 and the lower cover 5 are locked and installed by fixing bolts 6 to form the condensation chamber.
[0036] Example 1
[0037] A steam exhaust hole with a sloped structure similar to the pointed corner of an eave is formed on the first steam baffle 11 of the steam condensation baffle 4 through a mold stamping process, and the opening direction of the steam exhaust hole is facing the side. When the steam is discharged onto the steam condensation baffle 4, it moves toward the upper cover along the baffle slope composed of the first steam baffle 11 and the second steam baffle 8 and the exhaust hole. This process increases the steam movement stroke and improves the steam condensation efficiency. At the same time, the baffle slope allows the hanging beads produced by condensation to flow down along the baffle slope. The baffle slope is designed with oblique punching holes, which are used to discharge excess steam and can discharge steam along the oblique direction of the punching holes. The direction of the punching holes is toward the rear of the steam exhaust box, so that the steam is discharged toward the rear of the stove when it is exhausted, away from the front burner, to avoid affecting the combustion of the stove.
[0038] A steam cover is designed above the steam exhaust box. The steam cover has punching holes or strip holes for discharging the steam inside the exhaust box cavity so that the steam can be extracted by the range hood above.
[0039] As described in the exhaust box of the first aspect of the utility model, the angle between the center line of the guide plate and the normal line of the plane of the steam condensation baffle 4 is: 15°-65°.
[0040] As described in the exhaust box of the first aspect of the utility model, a steam sealing gasket 3 is arranged between the upper cover 2 and the steam condensation baffle 4.
[0041] As described in the exhaust box of the first aspect of the utility model, the bottom surface of the upper cover 2 extends downward around the air outlet to form a mounting groove, and the steam condensation baffle 4 and the lower cover 5 are installed on the mounting groove.
[0042] As described in the exhaust box of the first aspect of the utility model, a steam sealing gasket 3 is provided at the edge of the installation groove.
[0043] Example 2
[0044] The steam condensation baffle 4 structure of the utility model is as shown in the attached Figure 2 and 3As shown, one long side of the first steam baffle 11 is connected to one long side of the second steam baffle 8 to form a V-shaped groove shape, and two triangular connecting plates 9 are connected, and the adjacent sides of the triangle are respectively connected to the side edges of the first steam baffle 11 and the second steam baffle 8.

The steam condensation baffle 4 is made of metal material, such as thin-walled aluminum plate, thin-walled copper plate, and the steam condensation baffle 4 is made using sheet metal technology. The steam condensation baffle 4 has a first steam exhaust hole 12. When high-temperature steam passes through the steam condensation baffle 4, the baffle can effectively condense the steam. When the high-temperature steam enters the exhaust box through the lower cover, the high-temperature steam encounters a metal baffle with a lower temperature. The steam is cooled and condensed to form water droplets hanging on the back of the steam condensation baffle 4.
[0045] As more and more water droplets accumulate, the condensed water will automatically flow to the lower cover and return to the interior of the steam oven cavity through the exhaust pipe designed on the exhaust box below. This structure can effectively reduce the steam in the steam oven and increase steam condensation while achieving the same volume of steam exhaust.
[0046] As described in the exhaust box of the first aspect of the utility model, the steam condensation baffle 4 comprises: a flange 7, a first steam baffle 11, a second steam baffle 8 and two connecting plates 9;
