Description

a steam oven

technical field

The invention relates to the technical field of kitchen equipment, in particular to a steam oven.

Background technique

A steamer is a commonly used kitchen equipment, and there is a steam generating device inside the steamer that can produce steam. The steamer also includes an inner tank capable of holding dishes. The steam generating device inputs steam into the inner pot, and the steam contacts the food so as to heat and cook the food.

With the development of science and technology, many steam ovens are now integrated steam ovens. Not only can steam be injected into the inner tank to cook the ingredients, but also hot air can be blown into the inner tank to heat the ingredients.

However, no matter if it is a steamer, an oven or an all-in-one steamer. The space of the inner tank is relatively closed, and with the continuous input of steam or hot air, the pressure of the inner tank will gradually increase. For the sake of cooking safety, there is an air duct connected to the inner tank on the oven, so that steam and hot air can be discharged to the outside environment.

Since the air outlet of the air duct is directly set on the surface of the steam box, when the user uses it, the discharged steam or hot air is directly discharged to the user, which affects the user experience.

SUMMARY OF THE INVENTION

Therefore, the technical problem to be solved by the present invention is to overcome the defect that the steam oven in the prior art discharges steam and/or hot air toward the user, thereby providing a steam oven.

A steam oven comprising:

a box body, including an air outlet set on the box body;

Also includes:

The air guide assembly includes a plurality of air guide members arranged on the air outlet, and the air guide member divides the air outlet into a plurality of air discharge channels.

The air outlet extends in a horizontal direction, and the air outlet channel is inclined to both ends in the length direction of the air outlet.

The angle A between the exhaust passage and the direction facing the steam oven is (0, 60°].

The air guide includes:

a connecting shaft, which is rotatably connected to the box body;

The protruding block is arranged on the connecting shaft, and the box body is provided with a limiting hole for the protruding block to rotate.

The raised portion includes:

The first raised part and the second raised part are arranged close to the output end of the fan, and the first raised part and the second raised part are formed to guide the steam and/or the hot air away from the fan of the exhaust channel flow.

The air guide is arc-shaped.

The thickness of the air guide member gradually decreases along the direction away from the box body.

The technical scheme of the present invention has the following advantages:

1. The steam oven provided by the present invention includes: a box body, including an air outlet arranged on the box body; and also includes: an air guide assembly, including several air guide pieces arranged on the air outlet, the air guide The air outlet is divided into several air exhaust channels.

When the hot air is discharged from the box through the air outlet, it will be discharged along the air exhaust channel under the influence of the guide of the air guide. Therefore, by setting exhaust passages with different orientations, the hot air is discharged in the set area, so as to avoid a space for users to operate. Thus, the hot air is prevented from being directly discharged toward the user, and the user experience is improved.

2. In the steam oven provided by the present invention, the air outlet extends in a horizontal direction, and the air outlet channel is inclined to both ends of the air outlet in the length direction.

The length direction of the discharge port corresponds to the width of the front of the steamer. When the user uses and operates the steamer, they usually operate the steamer. In this solution, the exhaust channel is inclined towards both ends of the length direction of the exhaust port, which avoids the area in front of the steamer. The situation where the hot air is blown towards the user improves the user's experience.

3. In the steamer provided by the present invention, the angle A between the exhaust passage and the direction facing the steamer is (0, 60°].

Since the inclination angle of the exhaust channel is controlled by the air guide, in this solution, the inclination angle of the exhaust channel is prevented from being in the range of (0, 60°), and the exhaust channel is prevented from being closed due to an excessively large inclination angle.

4. In the steam oven provided by the present invention, the air guide includes: a connecting shaft, which is rotatably connected to the box body; a bump is arranged on the connecting shaft, and the box body is provided with a A limit hole for the protrusion to rotate.

The convex block arranged on the connecting shaft rotates together with the connecting shaft, and the rotation of the connecting shaft can be controlled by toggling the convex block, so that the air guide member rotates to change the direction of the exhaust passage. The limiting hole is used to limit the rotation range of the protruding block, so that the air guide member rotates within a limited angle range.

When the bump rotates with the connecting shaft as the center, the area swept is a sector. The fan-shaped limit hole is closer to the rotation trajectory of the bump. By setting the size of the central angle corresponding to the sector, the rotation range of the bump is indirectly limited.

6. The steam oven provided by the present invention further comprises: an exhaust chamber, which is arranged in the box, one end is used to communicate with the inner liner, and the other end is an exhaust port; a fan is arranged in the exhaust chamber, and the fan The input end is connected to the inner tank, and the output end is arranged toward the air outlet.

The exhaust chamber provides a temporary storage space for the discharge of hot air. After the hot air is drawn into the exhaust chamber by the fan, it flows in the exhaust chamber, consuming a certain amount of kinetic energy, reducing the kinetic energy when the hot air is discharged, thereby reducing the space range that is directly affected when the hot air is discharged to the outside world.

7. In the steam oven provided by the present invention, the fan is arranged away from the air outlet.

Increase the distance that the hot air moves to the air outlet after entering the exhaust chamber, thereby further increasing the consumption of kinetic energy before the hot air is discharged to the outside.

8. The steam oven provided by the present invention further comprises: a protruding part, which is arranged between the fan and the air outlet and protrudes toward the air outlet from the side wall of the air outlet, and forms a guide. Wind arc.

The air guide arc surface guides the hot air entering the exhaust chamber to move against the air guide arc surface.

In the steam oven provided by the present invention, the protruding part includes: a first protruding part and a second protruding part, which are arranged close to the output end of the fan; the first protruding part and the second protruding part are The exhaust passages for guiding steam and/or hot air to flow away from the fan are formed between the raised portions.

Since the fan is located at the output end opening of the exhaust chamber, the space relative to the exhaust chamber is small. The exhaust port is a strip-shaped opening that spans most of the exhaust chamber or even the entire exhaust chamber. Therefore, the air guide arc surface guides the hot air to flow evenly in the exhaust chamber and to the exhaust channel away from the fan. guiding role. Make the hot air volume exhausted between each exhaust channel more uniform.

10. In the steam oven provided by the present invention, the air guide is arc-shaped.

The arc-shaped air guide has a certain resistance to the hot air, and guides the hot air to change the direction of movement along its own surface shape. The kinetic energy of the hot air is reduced, and the direct impact range of the hot air's outward discharge is reduced.

11. In the steam oven provided by the present invention, the thickness of the air guide member gradually decreases along the direction away from the box body.

The thickness of the air guide member gradually decreases along the direction away from the box body, that is, when the air guide member extends out of the box body, the thickness gradually decreases along the direction extending out of the box body. The size of the opening of the exhaust passage formed by the adjacent air guides is gradually increased. Therefore, on the premise that the hot air flow remains unchanged, the flow velocity of the hot air is slowed down to a certain extent. Under the same air resistance, the hot air with a relatively slow flow velocity has a relatively smaller influence range of the outward spray.
