Detailed Description

In order that those skilled in the art will better understand the technical concept of the present invention, a detailed description of specific embodiments of the present invention will be given below with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.

As shown in fig. 1 and 4, the cooking appliance 1 (e.g., air fryer) may include a drawer or basket for receiving food, the drawer being drawably disposed within a receiving cavity of a body of the cooking appliance 1. In addition, the cooking appliance 1 may also include other various types of cooking chamber structures for containing food. The cooking appliance 1 may have a door structure for opening or closing a cooking chamber for containing food or viewing the inside of the cooking chamber therethrough.

The door structure of the cooking appliance will be described below by taking a drawer structure of the cooking appliance as an example, as shown in the drawings, the door structure of the drawer may include a cover plate 2 and a viewing window 3 provided in the cover plate 2, and the cover plate 2 may be exposed to the outside to form a part of the appearance of the drawer. The visual window 3 is transparent, so that a user can conveniently observe the cooking condition of food in the drawer at any time through the transparent visual window 3. Generally, a drawer handle or door structure handle is provided to facilitate a user's grasping or pulling the drawer, for example, as shown in fig. 1 and 4, the drawer handle may be horizontally strip-shaped and extend outward substantially perpendicular to the cover plate 2 (as shown in fig. 1), or the drawer handle may extend from an upper side of the viewing window 3 toward a door structure bottom of the drawer or a lower side of the viewing window 3 (as shown in fig. 4) in an L-shaped bent shape. Fig. 1 and 4 show only two examples of drawer handles, and a wide variety of other types of handles also exist. In a word, the drawer handle needs to be held, grasped or pulled to be suspended at the outer side part of the cooking appliance 1 or the drawer, and the drawer handle and the visual window 3 are arranged at one side convenient for a user to operate or view, so that the drawer handle can shield the user from observing the cooking effect of food in the drawer through the visual window 3 to a certain extent. For example, the handle structure shown in fig. 1 may block a part of the view when the user looks from top to bottom, while the handle structure shown in fig. 4 may block a part of the view when the user looks from the front or side, thereby making the user experience poor (the user may feel that the handle is in the eyes or the viewing effect is affected).

Therefore, the utility model provides a door body structure comprising a foldable handle, and the door body structure can be folded and retracted when visual cooking is needed, for example, the foldable handle is rotated or folded to the edge or the outer side of the edge of a visual window, so that the condition that a user can observe the cooking effect of food in a cooking chamber through the visual window is prevented from being shielded by the handle of the door body structure, and the visual effect is increased.

As shown in fig. 2, as shown in fig. 1 to 5, foldable handles 10, 20 may be provided on the cover plate 2, and one end of the foldable handles 10, 20 may be mounted or fixed to the cover plate 2 at one side (as shown, an upper side) of the viewing window 3. The foldable handles 10, 20 may be configured to be rotatable between an unfolded position (shown in fig. 1 and 4) and a folded position (shown in fig. 2 and 5). In the deployed position, a user may grasp the handle to hold or pull the drawer end-to-end when it is desired to use the handle. In the folded position, the foldable handles 10, 20 may be located at or outside the edge of the viewing window 3 as a whole, thereby avoiding the foldable handles 10, 20 from obstructing the view in all directions and increasing the viewing effect as much as possible.

The foldable handle 10, 20 is rotatable or foldable from an unfolded position in which the handle body 12, 21 of the foldable handle 10, 20 is adjacent to the cover 2 toward a range adjacent to the cover 2 and away from the viewing window 3. More specifically, for example, as shown in fig. 1 to 3, from the unfolded position to the folded position, the handle body 12 of the foldable handle 10 is moved toward the cover 2, thereby retracting the foldable handle 10 to make the foldable handle 10 approach or close to the cover 2 as a whole, so that on one hand, the handle can be prevented from blocking the view, the visual effect can be increased, and in addition, the space required by the whole cooking appliance or drawer can be reduced, thereby facilitating the storage and reducing the storage space.

As shown in fig. 1 to 5, the foldable handles 10, 20 may be configured to be folded left, or right, or upward with respect to the door body structure. In the first embodiment shown in fig. 1-2, the foldable handle 10 is rotatable in a substantially horizontal plane, for example, to the left or to the right with respect to the door structure of the drawer. In the second embodiment shown in fig. 4 to 5, in order to rotate such an L-shaped handle out of the range of the viewing window 3, the L-shaped handle can be rotated substantially in a vertical plane, for example folded upwards (anticlockwise rotation or clockwise rotation).

The handle structure and the handle rotating mode provided by the utility model are only examples, and foldable handles with other shapes or rotating modes are also feasible as long as the foldable handles can meet the function of being capable of rotating out of the range of the visible window to avoid blocking the sight of a user.

With respect to the foldable handle 10 according to the first embodiment of the present invention, referring to fig. 1 to 3, the door structure of the drawer may further include a handle fixing piece 11, the handle fixing piece 11 may be provided to the cover plate, and one end of the foldable handle 10 may be pivotably coupled to the handle fixing piece 11. As shown in fig. 3, the handle holder 11 may include two portions bent at an angle to each other, one portion for fixing to the cover plate 2 and the other portion for receiving or supporting the foldable handle 10, which may be a horizontally extending connecting portion 14 of the handle holder 11, as will be described below.

The first end of the foldable handle 10 may be provided with a slot 15, for example, the slot 15 may be at an intermediate position in the thickness direction of the foldable handle 10 and open outward to receive the connecting portion 14 of the handle fixing 11. More specifically, the connection part 14 of the handle fixing piece 11 may be located in the slot 15, whereby the foldable handle 10 clamps the connection part 14 through the slot 15. Further, the rotation shaft member 13 may be vertically inserted into the foldable handle 10 (e.g., through a hole 16 provided at one end of the foldable handle 10) and the handle fixing member 11 to enable the foldable handle 10 to horizontally rotate about the rotation shaft member 13. The shaft member 13 may be a screw shaft, i.e., having both functions of screw fixing and shaft rotation, for example, the lower end of the shaft member 13 may be screwed into the foldable handle 10, and the shaft member 13 may be rotated together with the handle body 12 of the foldable handle 10. Of course, other types of pivot members may be provided.

With respect to the foldable handle 20 according to the second embodiment of the present invention, the foldable handle 20 is different from the foldable handle 10 of the above-described embodiment in structure and rotation manner. The foldable handle 20 may include a handle shaft 210 at a first end thereof, and the handle shaft 210 may be inserted into a cover through-hole 30 provided in the cover 2 and may be rotatable with respect to an axis of the cover through-hole 30.

Specifically, the handle shaft 210 may be inserted into the cover through hole 30 from one side (outer side) of the cover 2 and engaged with the shaft sleeve 22 inserted into the cover through hole 30 from the other side of the cover 2, and the shaft sleeve 22 may be fitted over one end (e.g., front end) of the handle shaft 210 protruding into the cover through hole 30. The bushing 22 may provide support and positioning for the handle shaft 210 to enable the handle shaft 210 to be centered within the cover plate throughbore 30. In addition, a threaded fastener 23 is inserted into the boss 22 to be coupled with the handle shaft 210 to fix the boss 22 and the handle shaft 210 together. Thus, the handle shaft 210 of the foldable handle 20 can rotate together with the boss 22 in the cover through-hole 30. Here, the handle shaft 210 may be generally horizontal, whereby the foldable handle 20 may be rotated in a vertical plane about the horizontal handle shaft 210.

The end surface of the boss 22 facing the handle shaft 210 may be provided with an insertion hole, and the end of the handle shaft 210 may have an insertion shaft inserted into the boss 22. Preferably, one of the inner sidewall of the boss 22 and the outer sidewall of the handle shaft 210 may be provided with a protrusion 211 (the protrusion 211 is shown in fig. 7 to be provided in the outer sidewall of the handle shaft 210), and the other is provided with a groove 221 (the groove 221 is shown in fig. 7 to be provided in the inner sidewall of the boss 22) to be fitted with the protrusion 211. By this engagement of the projection and the recess, relative rotation between the handle shaft 210 and the boss 22 can be prevented, and loosening of the threaded fastener 23 for fastening the handle shaft 210 and the boss 22 can be prevented.

In addition, in order that the foldable handle 20 does not accidentally loosen, swing or shift when rotated to the unfolded position or the folded position, structures for forming a stroke position are provided on the foldable handle 20 and the cover plate 2. Specifically, a first retaining groove 31 and a second retaining groove 32 may be disposed on an inner hole wall of the cover through hole 30 and spaced apart in a circumferential direction, a hole groove 212 may be disposed on a sidewall of the handle shaft 210, the hole groove 212 may extend from an outer surface of the circumferential sidewall of the handle shaft 210 toward an inside of the handle shaft 210, and a first end of an elastic stopper (a spring and a ball as will be described below) may be disposed in the hole groove 212 and a second end of the elastic stopper may abut against the inner hole wall of the cover through hole 30. When the foldable handle 20 is in the unfolded position, the second end of the elastic limiting member abuts against the first stopping groove 31, and when the foldable handle 20 is in the folded position, the second end of the elastic limiting member abuts against the second stopping groove 32.

Preferably, the elastic stopper may include a spring 25 and a ball 26 at one end of the spring 25, the end of the spring 25 remote from the ball 26 is inserted into the hole groove 212, and the spring 25 biases the ball 26 such that the ball 26 can slide along the inner wall of the hole of the cover through hole 30. By using the spring 25 and the marble 26, the friction of the foldable handle 20 when it is rotated can be reduced, and the initial resistance to moving the foldable handle 20 out of the unfolded position or the folded position can be reduced.

Here, fig. 4 and 5 show only two positions of the foldable handle 20, and only corresponding two catch grooves are provided in the cover through-hole 30 to stabilize the foldable handle 20 in the two positions, but the present invention is not limited thereto, and the foldable handle 20 may be rotated to other positions (e.g., clockwise from the unfolded position shown in fig. 4 to a position at an upper side edge of the visible window 3 or a position within the range of the visible window 3 according to other principles), and correspondingly, other catch grooves may be provided in the cover through-hole 30.

Further, as shown in fig. 8, an end of the cover through hole 30 facing the inside of the cover 2 may be provided with a first step 214, an end of the boss 22 facing the handle shaft 210 may abut on the first step 214, and the handle shaft 210 may be provided with a second step 213, an end surface of the second step 213 facing the boss 22 may abut on an outer surface of the cover 2. By providing a stepped detent for the boss 22 and the handle shaft 210, while tightening the boss 22 and the handle shaft 210 with the threaded fastener 23, the boss 22 and the handle shaft 210 can be securely clamped against the cover 2 of the drawer, preventing the boss 22 and the handle shaft 210 from being dislocated, e.g., preventing the boss 22 and the handle shaft 210 from being displaced toward the inside or outside of the cover 2.

The door structure provided with the viewing window and the foldable handle has been described in a drawer type structure in the above description and the accompanying drawings of the specification, however, the present invention is not limited thereto.
