Description

Technical Field

[0001] This utility model relates to the field of food cooking technology, and in particular to a lifting structure for an oven and an oven. Background Technology

[0002] CN119924714A discloses a multi-functional oven, including a cabinet, a cabinet door, a lifting device, and a lower heating device. The cabinet door is hinged to the cabinet, and at least one upper heating device is provided on the top of the inner cavity of the cabinet. At least one drawer is provided in the inner cavity of the cabinet, and the drawer slides into or out of the inner cavity of the cabinet. The lifting device is detachably mounted on the drawer, and the lower heating device is connected to the lifting device, which drives the lower heating device to rise and fall.

[0003] In the technical solution disclosed in CN119924714A, the upper heating device 5 can move back and forth when unfolded, but cannot move back and forth when folded. If the upper heating device could move and extend from the opening of the cavity when folded (upper heating device 5 is in a lower position), it would be more convenient to place heated containers or the like on the upper heating device 5 at a lower height.

[0004] In addition, since the upper heating device 5 starts heating after it rises, but the upper heating device 5 can sway back and forth at this time, the power supply wires and other components on the upper heating device 5 will also change position as the upper heating device 5 sways back and forth, resulting in low reliability.

[0005] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0006] The present invention employs a lifting structure for an oven, which is used to house the oven's accommodating cavity. The lifting structure includes a lifting device; the lifting device includes a lifting component, a fixing component, a sliding end drive component, and at least one set of connecting rods, wherein the set of connecting rods consists of two mutually hinged connecting rods; each connecting rod includes a hinged end, a sliding end, and a connecting portion between the two; the lifting component is equipped with a heating device; the lifting component and the fixing component are respectively equipped with connecting rod sliding structures; the connecting portions of the two connecting rods are hinged to each other; the sliding end drive component can drive the sliding end to slide linearly along the connecting rod sliding structure; the hinged ends of the two connecting rods are respectively hinged to the lifting component and the fixing component; the sliding ends of the two connecting rods are respectively linearly slidably connected to the lifting component and the fixing component through the connecting rod sliding structure; the lifting component is movably connected to a movable component, which can extend out of the accommodating cavity after moving relative to the lifting component.

[0007] The advantages of this invention are that, in the folded state, the movable part can extend out of the receiving cavity, making it convenient to place containers or other items on the movable part, and also improving reliability.

[0008] A further technical solution involves a linear sliding connection between the movable component and the lifting component.

[0009] This technical solution facilitates the operation of the movable part extending from the receiving cavity when the device is folded.

Detailed Implementation

[0026] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0027] As a specific embodiment, the oven of this utility model includes an oven body 9, which has a receiving cavity 91. The side of the receiving cavity 91 communicates with the outside to form a receiving cavity opening 911. The oven body 9 is connected to an oven door 92 that can at least partially cover the receiving cavity opening 911. For example, the oven door 92 is hinged to the oven body 9. The oven door 92 can be rotated to cover the receiving cavity opening 911, thus opening the oven door 92. The oven door 92 can also be rotated to expose the receiving cavity opening 911, thus closing the oven door 92. Of course, the oven door 92 can also be opened and closed by means of linear sliding connection or detachable connection with the oven body 9. It is easy to understand that the user can put containers containing food or the like into the receiving cavity 91 through the receiving cavity opening 911. However, there are shallow containers 31 with a shallow inner cavity depth and deep containers 32 with a deep inner cavity depth. Therefore, it is necessary to adjust the height of the containers accordingly.

[0028] At least one of the top inner wall of the cavity 91 and the lifting member 11 described later is provided with a heating device 8 to achieve internal heating. Of course, the heating device 8 can also be set in other positions, as long as it can achieve heating of the cavity 91. In other words, the oven is provided with a heating device 8 for heating the cavity 91.

[0029] The oven of this utility model embodiment also includes a lifting structure for the oven.

[0030] The present invention provides a lifting structure for an oven, which is used to be installed in the receiving cavity 91 of the oven.

[0031] The oven lifting structure of this utility model includes a lifting device 1.

[0032] The lifting device 1 includes a lifting component 11, a fixing component 12, a sliding end driving component 14, and at least one set of connecting rods 13, wherein the set of connecting rods 13 consists of two connecting rods 13 that are hinged to each other.

[0033] The connecting rod 13 includes a hinged end 131, a sliding end 132, and an interconnecting part 133 located between the two.

[0034] The lifting component 11 and the fixing component 12 are respectively provided with a connecting rod sliding structure 134; the connecting parts 133 of a set of two connecting rods 13 are hinged to each other, so that the set of two connecting rods 13 are hinged to each other.

[0035] The sliding end drive 14 can drive the sliding end 132 to slide linearly along the connecting rod sliding structure 134.

[0036] The hinged ends 131 of the two connecting rods 13 are respectively hinged to the lifting component 11 and the fixing component 12.

[0037] The sliding ends 132 of two connecting rods 13 are linearly slidably connected to the lifting member 11 and the fixing member 12 respectively through the connecting rod sliding structure 134. It is easy to understand that the connecting rod sliding structure 134 is a structure used in the prior art to achieve linear sliding connection. For example, the connecting rod sliding structure 134 is a circular rod, a linear groove set on the side wall 114 of the lifting member 11, or it can be a linear bearing or other structures.

[0038] The lifting member 11 is movably connected to a movable member 112, which extends out of the receiving cavity 91 after moving relative to the lifting member 11. The movable member 112 and the lifting member 11 can be hinged, or a linear sliding connection as described in the following embodiments, or other types of movable connection. For example... Figure 5 As shown, "extending from the receiving cavity 91" means that the movable member 112 has a receiving cavity opening 911 that extends beyond line LINE1 in the horizontal direction.

[0039] The working principle is as follows: Figure 5 As shown, starting from the state where the sliding end 132 is furthest from the hinge end 131, i.e., the folded state (it is easy to understand that the distance between the lifting member 11 and the fixing member 12 in the height direction is the smallest in the folded state), the sliding end driving member 14 drives the sliding end 132 to slide linearly along the connecting rod sliding structure 134 for a sliding distance of 139, so that the sliding end 132 is close to the hinge end 131, until the sliding end 132 is closest to the hinge end 131, at which point it is the unfolded state (it is easy to understand that the distance between the lifting member 11 and the fixing member 12 in the height direction is the largest in the unfolded state).

[0040] like Figure 5 As shown in LINE2, the horizontal position of the hinge end 131 remains unchanged during the process of changing from a folded state to an unfolded state, or vice versa. This ensures that the horizontal position of the lifting member 11 remains constant. Therefore, in the folded state, the movable member 112 can extend from the receiving cavity 91, facilitating the placement of items such as the container 3 on the movable member 112. Since the container 3 typically includes a shallower container 31 and a deeper container 32, after the container 3 and other items retract into the receiving cavity 91 along with the movable member 112, the lifting member 11 can rise and fall to match the height of the container 3 on the movable member 112. After the lifting member 11 rises, the horizontal position of the heating device 8 on the lifting member 11 remains constant, and the wires and other components connected to the heating device 8 on the lifting member 11 will not sway back and forth or change position, thus improving reliability.

[0041] As one specific implementation, the movable member 112 is linearly slidably connected to the lifting member 11. For example, the lifting member 11 is provided with a movable connection structure 111, which is a linear groove; the side wall of the movable member 112 is embedded in the movable connection structure 111, so that the movable member 112 and the lifting member 11 are linearly slidably connected. Of course, the movable connection structure 111 can also be a linear guide rail or the like. This implementation facilitates the operation of the movable member 112 extending from the receiving cavity 91 in the folded state.

[0042] As one specific implementation, the hinged end 131 is closer to the opening of the receiving cavity 91 (i.e., the receiving cavity opening 911) than the sliding end 132. A support foot 113 is movably connected to the end of the movable member 112 furthest from the sliding end 132, for example, a hinged support foot 113. In the folded state, the support foot 113 can move and abut against a reference surface, which refers to the plane on which the oven body 9 is placed, such as the tabletop on which the oven body 9 is placed. In the folded state, after the movable member 112 extends from the receiving cavity opening 911, the support foot 113 abuts against the reference surface, ensuring that the movable member 112 will not bend or deform due to the weight of the container part 3 on it, thus ensuring high reliability.

[0043] As one specific implementation, the lifting device 1 also includes a sliding end drive member 14 with linear power, and the sliding end drive member 14 is connected to a linkage rod 141; one end of the linkage rod 141 is connected to the sliding end 132, and when viewed from above, the sliding end drive member 14 is completely located within the lifting device 11. This implementation saves space and makes the lifting device 1 a single unit, enabling convenient pre-assembly outside the receiving cavity 91. The linkage rod 141 is fixed to the sliding end drive member 14 by a linkage rod mounting bracket 149.

[0044] As one specific implementation, the connecting rods 13 are in two sets, and the sliding end drive member 14 is disposed between the two sets of connecting rods 13. It is easy to understand that the two ends of the linkage rod 141 are respectively connected to the sliding ends 132 of the two sets of connecting rods 13.

[0045] As one of the specific implementation methods, the oven lifting structure of the utility model embodiment also includes a power structure 2; the power structure 2 includes a drive gear 21 with rotational power, and the sliding end drive member 14 is a rack and meshes with the drive gear 21.

[0046] As one specific implementation, the lifting structure for the oven in this embodiment of the utility model also includes a power device 29. The power device 29 is a device such as a motor or a handle that can provide rotational power. The power device 29 drives and connects to a vertically arranged transmission rod 22. The fixing member 12 is provided with a drive gear hinge seat 219. The drive gear 21 is hinged to the drive gear hinge seat 219 and is provided with a driven end 211. The transmission rod 22 is connected to the driven end 211, thereby enabling the drive gear 21 to have rotational power. Typically, the transmission rod 22 is hinged to the transmission rod hinge seat 229, and the transmission rod hinge seat 229 is fixed to the oven body 9. The connecting rod of the drive gear 21 (not shown in the figure) passes through the through hole 125 of the fixing member side wall 124 of the fixing member 12, and the driven end 211 of the drive gear 21 meshes with the driving end 221 of the transmission rod 22.

[0047] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0048] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0049] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0050] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
