Detailed Description

As shown in fig. 1 to 4, a steam oven includes an oven main body including an outer case 13, a door assembly 14, and an inner case disposed in the outer case 13, in which an inner case 11 is disposed, the inner case 11 having an inner cavity 111 for cooking food.

The steam oven is provided with a condensation structure and an air duct 5 structure, as shown in fig. 5 to 10, a condensation cover 3 is arranged on the upper end surface of the inner shell, and the air duct 5 is formed between the condensation cover 3 and the oven main body (more specifically, the inner shell).

The condensation cover 3 is formed with a condensation cavity 31, the condensation cover 3 is provided with a steam inlet 32 and a steam outlet 33, the steam inlet 32 is communicated with the inside of the inner container 11 (namely, the inside of the oven main body), and the steam outlet 33 is communicated with the air duct 5.

The bottom of the condensation chamber 31 is disposed obliquely to have a first end located higher and a second end located lower, and the steam inlet 32 is disposed at the second end of the condensation chamber 31. Therefore, after the steam is condensed into water drops in the condensation chamber 31, the steam is automatically gathered in the steam inlet 32 under the action of gravity, and can flow back into the inner cavity 111 of the inner container 11 through the steam inlet 32.

The steam inlet 32 is a groove provided on the second end of the condensation chamber 31, and the groove extends from the inside of the condensation chamber 31 to the outside of the condensation chamber 31 through the sidewall of the condensation chamber 31. The steam outlet 12 is arranged at the upper rear end of the inner container 11, the steam outlet 12 is communicated with the steam inlet 32 through a pipeline, and the steam outlet 12 is lower than the steam inlet 32, so that steam is condensed into water drops and can easily flow back to the inner cavity 111 of the inner container 11 through the steam inlet 32.

The steam outlet 33 is arranged at the first end of the condensation cavity 31, the blocking lip 34 is arranged at the bottom of the condensation cavity 31 corresponding to the steam outlet 33, and the blocking lip 34 is annularly arranged around the periphery of the steam outlet 33, so that on one hand, the blocking lip 34 blocks steam from being condensed into water drops to flow out to the steam outlet 33, on the other hand, the path of the steam from the steam inlet 32 to the steam outlet 33 is increased, and the time of steam staying in the condenser for condensation is increased so as to improve the condensation effect. Of course, as a variation of this structure, the steam outlet 33 is disposed at the first end of the condensation chamber 31, the bottom of the condensation chamber 31 corresponds to the steam outlet 33, and a blocking plate is disposed between the steam inlet 32 and the steam outlet 33, the blocking plate may be a whole flat plate, or may be an arc plate having a central axis coaxial with the central axis of the steam outlet 33, and the blocking plate, regardless of the flat plate or the arc plate, serves the same function as the blocking lip 34. Of course, as a variation of this structure, the steam outlet 33 may be disposed on a side wall near the first end of the condensation chamber 31, and as above, a blocking plate may be disposed at the bottom of the condensation chamber 31 corresponding to the steam outlet 33 and extending into the condensation chamber 31 between the steam inlet 32 and the steam outlet 33, the blocking plate may be a one-piece flat plate, or may be an arc plate having a central axis coaxial with the central axis of the steam outlet 33, and it should be noted that the structure using the blocking plate is not shown in the drawings.

One end of the air duct 5 is an exhaust port 51, and the other end of the air duct 5, which is far away from the exhaust port 51, is provided with an exhaust fan 6 for blowing air into the air duct 5, wherein the exhaust fan 6 has the functions of increasing the flow rate of steam in the air duct 5 and cooling; the condensation cover 3 is provided with a wind shield 35 on the outer wall facing the oven main body corresponding to the steam outlet 33, specifically, the wind shield 35 is arranged between the exhaust fan 6 and the steam outlet 33, or the wind shield 35 is annularly arranged around the periphery of the steam outlet 33, or the wind shield 35 is an arc plate with a central axis coaxial with the central axis of the steam outlet 33. If no wind shield 35 is arranged, part of the steam which is not ready to be condensed in the condensation cavity 31 can not enter the air channel 5 and is blown to the condensation cavity 31 reversely, so that smooth flowing of the air in the condensation cavity 31 is influenced, and after the wind shield 35 is arranged, the air from the steam outlet 33 can be guided to the middle position of the air channel 5, can be clamped by the fluid in the air channel 5 fully and can be cooled fully, so that the temperature of the air reaching the exhaust port 51 is not high, and safe emission is realized.

In the direction in which the second end of the air duct 5 extends toward the first end, the air duct 5 is divided into an intake section 52, a diffuser section 53, and a discharge section 54 in this order; in a cross direction perpendicular to a cross section of the second end of the air duct 5 extending towards the first end, the air duct 5 is flared at the inlet section 52, the opening of the flare facing the exhaust fan 6; the diffusion section 53 is large in the middle and small at two ends, and the steam outlet 33 is positioned in the diffusion section 53; the discharge section 54 is flat. Through the specific shape of the air duct 5, different speeds of the fluid in the air duct 5 can be realized, and the temperature of the steam or gas condensed in the condensation cavity 31 can be reduced sufficiently, so that the temperature of the gas reaching the exhaust port 51 is not high, and safe discharge is realized.

The surface of the oven main body facing the condensation cover 3 is a plane; since the bottom of the condensation chamber 31 is disposed obliquely to have a first end located at a higher position and a second end located at a lower position, the bottom of the condensation chamber 31 and the oven body together constitute one end of the diffuser section 53 close to the entrance section 52. The condensation hood 3 is substantially parallel to the face of the oven body facing the condensation hood 3 in the exhaust section 54; the condensation hood 3 connects the discharge section 54 of the condensation hood 3 and the bottom of the condensation chamber 31 by means of the circular arc shape 36. The side wall of the condensation chamber 31 near the second end is smoothly connected with the bottom of the condensation chamber 31 through the arc-shaped plate 37 to form an inlet section 52 of the air duct 5 in the shape of a bell mouth. In a longitudinal direction perpendicular to a cross section of the second end of the air duct 5 extending towards the first end, a longitudinal dimension of the second end of the air duct 5 is smaller than a longitudinal dimension of the first end of the air duct 5, and the second end of the air duct 5 and the first end of the air duct 5 are in transition connection through a transition section 38.

Because the water supply tank 9 is connected with the steam generating device, sometimes the steam generated by the steam generating device flows back to the water supply tank 9 to cause the water temperature of the water supply tank 9 to rise and generate water scale, by arranging the water storage tank 81 and the water supply tank 9, cold water can be stored in the water storage tank 81, when the food is to be steamed and baked by using the steam oven, the cold water is conveyed to the water supply tank 9 through a pipeline, and the possibility of generating water scale caused by the water temperature rise of the water supply tank 9 is reduced.

The steam generating device comprises a heating basin 83 and a heating assembly 84, the heating basin 83 is formed at the bottom of the inner cavity 111 to hold the feed water of the water tank 9, and the heating assembly 84 is arranged above the inner shell and below the heating basin 83 to heat the feed water on the heating basin 83 to form steam.

The water pump 82 is controlled by a control device, the water storage cavity is also provided with a liquid level detection device 93, and the liquid level detection device 93 detects a liquid level feedback signal of liquid in the water storage cavity and sends the liquid level feedback signal to the control device so as to control the water pump 82 to be started or closed.
