Example 1:

referring to fig. 1 to 2, the present embodiment provides a cooking apparatus, which specifically includes a cabinet 1 and a door 2.

Referring to fig. 3, the inside of the case 1 is used for cooking food, a case opening 11 communicating with the inside of the case 1 is formed on the outer wall of the case 1, and food enters and exits the inside of the case 1 through the case opening 11. The cooking means of the case 1 for food may be one or more of common cooking modes such as steaming, boiling, baking, etc. Depending on the specific cooking mode that the case 1 can realize, the cooking apparatus in this embodiment may be cooking apparatuses such as an oven, a steam box, or a steaming and baking all-in-one machine, so that the specific kind of the cooking apparatus is not limited in this embodiment.

The door body 2 is movably arranged at the box opening 11, and the door body 2 is used for sealing the box opening 11 in the process of cooking the objects in the box body 1. The door 2 may be movable in a translational manner, a rotational manner, a combination of translational and rotational manners, or any other conventional manner as will occur to those of skill in the art. Of course, as a common mounting manner of the door body 2, the present embodiment takes a case where the door body 2 is rotatably provided at the box opening 11 as an example, and will be described in detail later.

The box 1 is provided with a push member 3, and the push member 3 is usually a push rod, and the push member 3 can move along a first direction on the box 1. The first direction is a straight line direction, in other embodiments, the first direction is in a non-parallel relationship with the axial direction of the push rod, and in the present embodiment, the first direction is the axial direction of the push rod. More specifically, in this embodiment, the push rod and the motor are combined to form an electric push rod, and the ejector 3 is controlled to move on the case 1 along the first direction in an electric control manner.

Referring to fig. 4, the door body 2 has an abutment surface 21 on a side thereof adjacent to the bin mouth 11. When cooking is performed in the case 1, the middle of the door 2 is opposite to the case opening 11, and the temperature is high, so in this embodiment, the abutting surface 21 is located at the edge of the door 2, so as to reduce the influence of heat on the abutting surface 21 and reduce the thermal deformation of the abutting surface 21.

When the cooking of the food in the box body 1 is just finished, the door body 2 is covered at the box opening 11, the ejector 3 and the abutting surface 21 are opposite in the first direction, and the ejector 3 moves along the first direction so as to realize the rotation of the door body 2 at the box opening 11 by pushing the abutting surface 21, thereby opening the box opening 11. At the moment of automatic opening of the tank opening 11, the tank body 1 instantaneously discharges a large amount of hot steam to the outside of the tank opening 11, and the user does not need to stand at the tank opening 11 to operate the door body 2, so that the hot steam is less or does not contact the user.

In this embodiment, the rotation axis of the door body 2 is located at the bottom of the box opening 11, and the ejector 3 is located above the box opening 11, so in this embodiment, the ejector 3 pushes the top of the door body 2 to leave the box opening 11, so that the door body 2 integrally rotates downward, and when the door body 2 rotates by a certain angle, the door body 2 does not need to be pushed by the ejector 3, but rotates spontaneously under the action of self gravity, so as to completely open the box opening 11. The shape of the abutment surface 21 is not particularly limited, and only needs to match with the shape of the end surface of the ejector 3, so that the ejector 3 can normally push the door body 2 to rotate.

More specifically, in this embodiment, the first direction and the rotation axis of the door body 2 are perpendicular to each other.

In the above process, due to the mismatch between the translational movement of the ejector 3 in the first direction and the rotational movement of the door body 2, the ejector 3 also slides with each other between the end face and the abutment face 21 during the rotation of the door body 2, thereby generating frictional noise.

In order to reduce the volume of the friction noise, a plurality of avoidance gaps 211 are formed on the abutting surface 21 in this embodiment. The specific kind of the avoidance space 211 may be a slot, a through hole or a blind hole. When the number of the avoidance gaps 211 is two or more, the specific kinds of the different avoidance gaps 211 may be the same or different. Preferably, all avoidance gaps 211 are blind holes, and the reason is that the inside of the door body 2 is of a hollow structure, and the avoidance gaps 211 are designed to be blind holes, so that dirt can be prevented from entering the inside of the door body 2 through the avoidance gaps 211.

The specific principle of avoiding the empty space 211 and reducing friction noise is that two points are respectively:

1. after the avoidance of the empty space 211 is formed, the avoidance of the empty space 211 does not cause the outward protrusion of the abutting surface 21, so that the surface roughness of the abutting surface 21 is not changed, and meanwhile, the contact position of the end surface of the ejector 3 and the door body 2 is always on the abutting surface 21 instead of the inside of the avoidance of the empty space 211, so that the friction coefficient between the end surface of the ejector 3 and the door body 2 is always the friction coefficient between the end surface of the ejector 3 and the abutting surface 21;

therefore, preferably, the edge of the opening of the avoidance gap 211 at the abutting surface 21 is arc-shaped, so that the possibility that the edge of the opening of the avoidance gap 211 scratches the end surface of the ejector 3 is reduced, and the increase of the roughness of the end surface of the ejector 3 is avoided as much as possible;

2. the avoidance void 211 breaks a portion of the abutment surface 21 without contacting the end face of the ejector 3, so that the area of the abutment surface 21 is smaller than without the avoidance void 211. The contact area between the end face of the ejector 3 and the abutment surface 21 is reduced when there is a relief void 211 at the contact position of the end face of the ejector 3 and the abutment surface 21. Since the contact area and the frictional noise are positively correlated, the frictional noise between the end surface of the ejector 3 and the abutment surface 21 decreases when the contact area decreases.

According to the principle that the gap 211 is avoided and friction noise is reduced, the end face of the ejector 3 needs to be always partially abutted against the abutting surface 21 in the process of pushing the door body 2, and the end face of the ejector 3 is prevented from entering the gap 211 to be avoided and contacting with the inner wall surface of the gap 211 through the limiting effect of the abutting surface 21 on the end face of the ejector 3. Accordingly, the number of the avoidance gaps 211, the distribution manner, the shape and the like of the abutment surface 21 should satisfy the condition that the end surface of the ejector 3 is only partially projected on the avoidance gaps 211 in the first direction, so as to avoid that the end surface of the ejector 3 completely enters the avoidance gaps 211.

It is easily conceivable that the avoidance gaps 211 would destroy part of the mechanical properties of the door body 2 itself, so that the number of dimensions and the like of the avoidance gaps 211 should be limited, and that all the avoidance gaps 211 should play a role in reducing friction noise as much as possible during the process of pushing the door body 2 to rotate by the end face of the ejector 3. The abutment surface 21 is thus planar in this embodiment, when the door 2 is closed at the opening 11, the abutment surface 21 is perpendicular to the first direction, and the abutment surface 21 is fully projected onto the end surface of the ejector 3 along the first direction. Therefore, when the door body 2 just starts to rotate, the abutting surface 21 and the end face of the ejector piece 3 are in an abutting state, all openings for avoiding the gaps 211 are located at the end face of the ejector piece 3, and all corresponding avoiding gaps 211 play a role in reducing friction noise for the first time. Then, with further rotation of the door body 2, different parts of the abutting surface 21 contact the edge of the end face of the ejector 3, that is, the position where the abutting surface 21 contacts the edge of the end face of the ejector 3 changes, so that a part of different positions of the abutting surface 21 avoid the empty space 211, and the effect of reducing friction noise for the second time is achieved. Thereby ensuring that all of the avoidance voids 211 act to reduce friction noise at least once.

As the door body 2 is moved, the portion of the abutment surface 21 projected to the end surface of the ejector 3 in the first direction gradually decreases. In some other embodiments, when the door body 2 is covered at the box opening 11, if the avoidance space 211 is not completely projected onto the end surface of the ejector member 3 along the first direction, but a part of the avoidance space 211 is projected onto the outer side of the end surface of the ejector member 3, the part of the avoidance space 211 projected onto the outer side of the end surface of the ejector member 3 cannot reduce friction noise for the first time, and the subsequent second time cannot reduce friction noise along with the rotation of the door body 2, which indicates that the size of the avoidance space 211 is too large, the excessive size cannot further reduce friction noise, and causes additional unnecessary damage to the mechanical performance of the door body 2.

It will be appreciated that, since the ejector 3 in this embodiment is a push rod, the end surface area thereof is small, and the area of the abutment surface 21 is small, so that the size and area of the avoidance space 211 are effectively limited, thereby reducing the influence on the mechanical properties of the door body 2.

From the above analysis, it is clear that the alignment effect between the end face of the ejector 3 and the abutment surface 21 is important. The temperature in the vicinity of the cabinet 1 is often high during long-term use of the cooking apparatus, which is liable to cause thermal deformation of the ejector 3, thereby possibly adversely affecting the alignment effect between the end face of the ejector 3 and the abutment face 21. In this case, the case 1 is provided with a guide through hole 12 extending in the first direction, and the end of the ejector 3 is positioned in the guide through hole 12, and deformation of the ejector 3 is suppressed by the guide through hole 12, so that when the door 2 is closed to the case opening 11, the end surface of the ejector 3 always faces the abutment surface 21 in the first direction.

Further, when the door body 2 is covered at the box opening 11, the abutment surface 21 is located at the end of the guide through hole 12, so that the guide through hole 12 is blocked by the abutment surface 21, and a relatively airtight space is formed by the end of the ejector 3 and the abutment surface 21. During the long-term unused period of the cooking equipment, the airtight space can protect the avoidance vacancy 211, reduce the dirt entering the avoidance vacancy 211, reduce the cleaning frequency of the avoidance vacancy 211, and enable the avoidance vacancy 211 to keep a good friction noise reduction effect for a long time.

Based on the feature that the rotation axis of the door body 2 is located at the bottom of the box opening 11, and the push rod is located above the box opening 11, when the door body 2 is completely opened, the avoidance gap 211 is upward, and is generally opposite to a lamp on a ceiling of a user, and meanwhile, the avoidance gap 211 is located at one side of the door body 2 close to the user, so that the door body 2 can be quite conveniently cleaned when being completely opened in the embodiment.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
