Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a door handle and a cooking device. Background Art

[0002] Currently available built-in ovens, steamers, and other cooking appliances have a door on the front for opening and closing the cooking chamber. Typically, the handle is located above the door and protrudes outward. Once installed, the handle is exposed outside the cabinet, making it easy for users to collide with the handle while walking in the kitchen, potentially causing injury.

[0003] To avoid this problem, existing door handles are hinged to the door. When the user needs to pull the door, the handle protrudes from the door, facilitating the user's movement. When the user no longer wishes to pull the door, the handle retracts toward the door, flush with the surface. This arrangement effectively addresses the issue of users easily bumping into handles while walking in the kitchen. However, since the cooking equipment generates heat that reaches the door surface when operating, the door's surface temperature is high. This makes it very easy for the user's hand to touch the door when pulling it with the handle, potentially causing burns. Utility Model Content

[0035] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] like Figures 1 to 8 As shown, the utility model provides a cooking device, including a cooking cavity 100, a door body 200 and a door handle. The cooking cavity 100 has an opening. The door body 200 is pivotally connected to the cooking cavity 100 by a hinge for opening and closing the opening. The handle 1 is movably connected to the door body 200 through a hinge assembly 2.

[0037] Optionally, the door body 200 includes an inner door panel 201, and outer glass 202 and inner glass 203 arranged on both sides of the inner door panel 201. When the door body 200 closes the opening, the inner glass 203 is opposite to the opening. A control panel 300 is spaced apart above the door body 200. The handle 1 is movably connected to the top of the door body 200. When the handle 1 is in the second position, the handle 1 closes the gap between the door body 200 and the control panel 300, and at this time the door body 200, the handle 1 and the control panel 300 are located in the same plane. In other embodiments, the handle 1 can also be located behind the outer surface of the outer glass 202. This setting can prevent the handle 1 from causing harm to the user. When the handle 1 is in the first position, the handle 1 is located in front of the outer surface of the outer glass 202. This position makes it convenient for the user to grab the handle 1.

[0038] When the cooking device is working, the heat in the cooking cavity 100 will be transmitted to the inner glass 203, the inner door panel 201 and the outer glass 202 in sequence. If the handle 1 is too close to the outer glass 202 at this time, when the user pulls the handle 1, the user's hand can easily touch the outer glass 202, thereby causing burns to the user's hand.

[0039] To avoid the above problems, Figures 1 to 8As shown, this embodiment provides a door handle, which includes a handle 1 and a hinge assembly 2. The hinge assembly 2 includes a main rotating plate 21 and a secondary rotating plate 22. One end of the main rotating plate 21 is pivotally connected to the handle 1, and the other end is used to pivotally connect to the door body 200. One end of the secondary rotating plate 22 is pivotally connected to the handle 1, and the other end is used to pivotally connect to the door body 200. In the vertical direction, the pivot axis of one end of the secondary rotating plate 22 is located above the pivot axis of one end of the main rotating plate 21, and the pivot axis of the other end of the secondary rotating plate 22 is located above the pivot axis of the other end of the main rotating plate 21. The axis is located below the pivot axis at the other end of the main rotating plate 21, and the hinge assembly 2 enables the handle 1 to have a first position and a second position. The first position is that the handle 1 is located in front of the outer surface of the door body 200, and the second position is that the handle 1 is flush with the outer surface or located behind the outer surface. The handle 1 is in the first position, the main rotating plate 21 and the secondary rotating plate 22 abut against each other, and the distance between the pivot axis center at one end of the main rotating plate 21 and the pivot axis center at one end of the secondary rotating plate 22 is a, a≤12mm.

[0040] The main rotating plate 21, the secondary rotating plate 22, the door body 200 and the handle 1 form a four-bar structure, the main rotating plate 21 and the secondary rotating plate 22 are two long rods, the handle 1 between one end of the main rotating plate 21 and one end of the secondary rotating plate 22 constitutes a short rod, and the door body 200 between the other end of the main rotating plate 21 and the other end of the secondary rotating plate 22 constitutes another short rod. By driving the other end of the main rotating plate 21 to rotate, the handle 1 can be switched between the first position and the second position.

[0041] The distance between the other end of the primary rotating plate 21 and the other end of the secondary rotating plate 22 is fixed. When the distance a between the pivot axis of one end of the primary rotating plate 21 and the pivot axis of one end of the secondary rotating plate 22 is changed, the time when the primary rotating plate 21 and the secondary rotating plate 22 come into contact when the handle 1 is in the first position changes, which in turn causes the rotation angle of the primary rotating plate 21 and the secondary rotating plate 22 to change, ultimately causing the distance between the handle 1 and the door body 200 to change. Specifically, the smaller the distance a between the pivot axis of one end of the primary rotating plate 21 and the pivot axis of one end of the secondary rotating plate 22, the later the primary rotating plate 21 and the secondary rotating plate 22 come into contact, which in turn causes the rotation angle of the primary rotating plate 21 and the secondary rotating plate 22 to increase, ultimately causing the distance between the handle 1 and the door body 200 to increase. Specifically, the distance a between the pivot axis of one end of the primary rotating plate 21 and the pivot axis of one end of the secondary rotating plate 22 is ≤12 mm.

[0042] Optionally, along the vertical direction, the distance between the pivot axis of one end of the secondary rotating plate 22 and the upper end surface of the handle 1 is b, and b≤10mm. In this embodiment, when the handle 1 is in the second position, when one end of the secondary rotating plate 22 is pivotally connected to the portion of the handle 1 near the lower end surface along the vertical direction, the distance from one end of the secondary rotating plate 22 to the other end is L, and when one end of the secondary rotating plate 22 is pivotally connected to the portion of the handle 1 near the upper end surface along the vertical direction, the distance from one end of the secondary rotating plate 22 to the other end is b. Obviously, b>L. When the handle 1 switches from the second position to the first position, since b>L, when one end of the secondary rotating plate 22 is pivotally connected to the portion of the handle 1 near the upper end surface along the vertical direction, the distance between the handle 1 and the door body 200 is farther, thereby better preventing burns to the user's hands. When the position of one end of the secondary rotating plate 22 is determined, the position of one end of the main rotating plate 21 is also determined accordingly.

[0043] Optionally, the distance between the pivot axis at one end of the primary rotating plate 21 and the inner end surface of the handle 1 is c, c ≤ 8 mm, and the distance between the pivot axis at one end of the secondary rotating plate 22 and the inner end surface of the handle 1 is d, d ≤ 8 mm. In this embodiment, the above arrangement can further increase the distance between the handle 1 and the door body 200.

[0044] Optionally, the base 121 and the pivoting ear 122 form a pivot seat 12, and the handle 1 includes a handle portion 11 and a pivoting seat 12 fixed to the handle portion 11. The base 121 is fixed to the side of the handle portion 11 close to the door body 200, and the pivoting ear 122 is fixed to the base 121. One end of the primary rotating plate 21 and one end of the secondary rotating plate 22 are respectively pivotally connected to the pivoting ear 122. In this embodiment, the base 121 is bonded to the wall surface of the handle portion 11 close to the door body 200. A plurality of pivoting ears 122 are provided, and the plurality of pivoting ears 122 are spaced apart along the length direction of the handle portion 11. A plurality of hinge assemblies 2 are provided, and the plurality of hinge assemblies 2 correspond one-to-one to the plurality of pivoting ears 122. The pivoting ears 122 and the base 121 are integrally formed.

[0045] Optionally, the surface of the base 121 provided with the pivoting ear 122 is vertically divided into a lower curved surface 1211 and an upper curved surface 1212. The thickness of the base 121 gradually decreases along a direction perpendicular to the handle 11 from the intersection of the lower curved surface 1211 and the upper curved surface 1212 to the two sides where the lower curved surface 1211 and the upper curved surface 1212 are separated from each other. In this embodiment, the above arrangement allows the user's hand to increase the distance from the door body 200 regardless of whether the user is holding the lower curved surface 1211 or the upper curved surface 1212, thereby reducing the chance of burns.

[0046] Optionally, both the lower curved surface 1211 and the upper curved surface 1212 are curved surfaces. In this embodiment, compared to a flat surface, the curved surface is less likely to slip when the user pulls the handle 1, and can further away from the door body 200. In other embodiments, it can also be a flat surface.

[0047] Optionally, when the handle 1 is in the first position, the intersection of the lower curved surface 1211 and the upper curved surface 1212 is configured to be higher than the door body 200 along the vertical direction. In this embodiment, the intersection of the lower curved surface 1211 and the upper curved surface 1212 is the closest point to the door body 200. If the intersection line of the lower curved surface 1211 and the upper curved surface 1212 is lower than the door body 200, it is easy to cause burns to the user's hand at the intersection. Therefore, in this embodiment, the intersection of the lower curved surface 1211 and the upper curved surface 1212 is higher than the door body 200.

[0048] Optionally, the main rotating plate 21 and the secondary rotating plate 22 are respectively provided with a first stop structure 211 and a second stop structure 221, the second stop structure 221 includes a first limiting surface 2211 and a second limiting surface 2212 at an angle, the first stop structure 211 is located between the first limiting surface 2211 and the second limiting surface 2212, the handle 1 is in the first position, the first stop structure 211 abuts against the first limiting surface 2211, the handle 1 is in the second position, the first stop structure 211 abuts against the second limiting surface 2212. In this embodiment, the first limiting surface 2211 and the second limiting surface 2212 are arranged to form an angle, and the first stop structure 211 is arranged between the first limiting surface 2211 and the second limiting surface 2212, so that when the handle switches between the first position and the second position, the first stop structure 211 moves toward the direction close to the first limiting surface 2211 or close to the second limiting surface 2212. Specifically, the second stop structure 221 also includes a connecting surface, which is respectively connected to the first limiting surface 2211 or close to the second limiting surface 2212. This setting increases the distance between the first limiting surface 2211 and the second limiting surface 2212, further improving the moving range of the handle 1.

[0049] Optionally, the first stop structure 211 includes a first abutting surface 2111 and a second abutting surface 2112, wherein the first abutting surface 2111 is opposite to the first limiting surface 2211, and the second abutting surface 2112 is opposite to the second limiting surface 2212. When the handle 1 is in the first position, the first abutting surface 2111 is in contact with the first limiting surface 2211, and when the handle 1 is in the second position, the second abutting surface 2112 is in contact with the second limiting surface 2212. In this embodiment, taking the first abutting surface 2111 and the first limiting surface 2211 as an example, the first abutting surface 2111 and the first limiting surface 2211 are in contact with each other, thereby increasing the abutting area. This can avoid stress concentration on the one hand, and improve the stability of the abutment between the primary rotating plate 21 and the secondary rotating plate 22 on the other hand. The structure and function of the second abutting surface 2112 and the second limiting surface 2212 are the same as those of the first abutting surface 2111 and the first limiting surface 2211 , and are not described in detail herein.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
