Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of heating device and oven with lifting function. BACKGROUND

[0002] As a common cooking equipment, oven is widely used in household kitchen and catering industry. The existing oven is usually equipped with upper and lower heating devices, which provide heat source for food materials in the cavity through the work of heating device, so as to complete various cooking tasks such as baking and roasting. However, in the existing design, the lower heating device is usually fixedly installed, and its position cannot be adjusted, which leads to the following problems:

[0003] Because the position of the heating device is fixed, the cooking space height inside the oven cannot be flexibly adjusted according to the size of the food material. For example, when dealing with thin food materials, the fixed heating device may not provide a proper heating distance, resulting in waste of heat energy or uneven heating; for thicker food materials, the space inside the oven may be insufficient, making it difficult to meet the actual cooking needs.

[0004] The existing heating device of the oven is usually fixed on the top or bottom of the cavity, and the user needs to adjust the position of the food material or use auxiliary tools (such as baking trays, pads) to change the distance from the heating device. This method not only is cumbersome to operate, but also may cause uneven heat distribution, thereby affecting the cooking effect of the food material. In addition, the fixed distance between the heating device and the food material may result in low heat energy utilization and increase the cooking energy consumption.

[0005] Because the heating device cannot be lifted, the cooking method of the oven is limited to a certain extent. For example, for food materials that need to be quickly baked at high temperature, the heating device cannot be adjusted to be close to the food material, affecting the baking efficiency; for food materials that need to be slow-cooked at low temperature, the fixed heating device at close distance may cause local overheating, which cannot achieve uniform heating. This single design cannot meet the needs of users for diversified cooking methods.

[0006] In actual use, different food materials have different requirements for heating conditions. For example, thin food materials such as pizza crusts require a smaller distance between the heating device and the food material to achieve rapid and uniform heating; while thicker meat or large-volume baked goods require a larger distance to avoid local overheating. However, due to the fixed position of the heating device in the existing oven, it is difficult to flexibly adapt to the diversified needs of food materials.

[0007] In summary, the fixed design of the built-in heating device in the existing oven has many limitations, especially in the flexible adjustment of cooking space, optimization of thermal efficiency and realization of diversified cooking methods. SUMMARY

[0008] The first purpose of the utility model is to provide a kind of heating device with lifting function, which can adjust the height of cooking space flexibly and improve the utilization rate of heat energy.

[0009] The second purpose of the utility model is to provide a kind of oven with lifting function, which can adjust the height of cooking space flexibly and improve the utilization rate of heat energy.

[0010] The first purpose of the utility model is achieved as follows:

[0011] A kind of heating device with lifting function, including lower heating device and lifting device, the lower heating device includes shell and lower heating pipe, the shell is opened with lower heating cavity, the lower heating pipe is arranged in lower heating cavity, the lifting device is connected with shell, and the shell is lifted by lifting device, so as to drive the lower heating device to lift.

[0012] The lower heating device is connected with the shell by the lifting device, which can flexibly adjust the position of the heating device according to the height requirement of food materials, and realize the dynamic adjustment of the height of cooking space. In this way, both the close-range heating required by thin food materials and the large cooking space required by thick food materials can be met.

[0013] By adjusting the height of the lower heating device, the user can optimize the distance between the food material and the heating device, so that the heat energy can be more concentrated on the surface of the food material, reducing heat loss and improving cooking efficiency. The more accurate heating distance can also avoid uneven heat distribution and improve the heating effect of the food material.

[0014] The lifting function enables the lower heating device to meet the heating distance requirements of different food materials, thereby adapting to various cooking methods such as baking, roasting, slow cooking, etc., and enhancing the functional diversity of the oven. For example, close to the lower heating device can realize rapid high-temperature roasting, and far away can meet the needs of low-temperature slow roasting.

[0015] Through the design of the lifting device, the user can more conveniently adjust the position of the heating device without the need for additional tools or manual adjustment of the position of the food material, the operation is more intuitive, and the use experience is greatly improved. At the same time, the complexity and inconvenience in the adjustment process are reduced.

[0016] The design of traditional oven fixed heating device often cannot be compatible with food materials of different sizes or shapes, while the heating device with lifting function can adapt to various sizes of cooking requirements, thereby widening the use range of the equipment.

[0017] The lifting function of the heating device enables the oven to utilize the cavity space more efficiently, and multiple heating requirements can be achieved without designing multiple layers of fixed heating devices, thereby simplifying the equipment structure, reducing the design complexity, and improving the overall performance of the equipment.

[0018] The first purpose of the utility model can also be solved by the following technical measures:

[0019] Further, the lifting device is a lifting support, the lifting support includes a first support and a second support, the first support and the second support are connected, the upper end of the first support is connected to the rear end of the shell, and the upper end of the second support is connected to the front end of the shell.

[0020] The first support and the second support are rotated, when the lower end of the first support and the lower end of the second support approach each other, the lifting support is unfolded to drive the lower heating device to rise, and when the lower end of the first support and the lower end of the second support move away from each other, the lifting support is folded to drive the lower heating device to descend.

[0021] The lifting support realizes the lifting function through the rotation of the first support and the second support, which is simple in design and convenient to operate.

[0022] The first support and the second support form a stable support structure through connection, which can effectively bear the weight of the lower heating device and avoid equipment damage or affected cooking effect due to unstable structure during lifting.

[0023] The lifting action is realized through the rotation of the support, which can accurately control the height of the lower heating device, so that the user can flexibly adjust the position of the heating device according to the cooking requirements, and improve the accuracy of the cooking effect.

[0024] The rotation design of the support allows the user to select multiple heights according to the size and heating requirements of different food materials, and flexibly adjust the cooking space size, so as to meet the diversified cooking methods and food material requirements.

[0025] The lifting support design enables the lower heating device to approach or move away from the food material, and accurately adjusts the heating distance.

[0026] When the support is folded, the lower heating device descends accordingly, which can minimize the vertical space occupied by the equipment when not in use, thereby optimizing the utilization rate of the oven internal space and enhancing the compactness of the equipment.

[0027] The bracket design makes the lifting action of the heating device more stable, reduces the risk of sudden sliding or shaking, improves the safety of the device, and is particularly suitable for high-frequency use in family and commercial environments.

[0028] Further, a lower baking tray is detachably arranged in the lower heating cavity and above the lower heating pipe.

[0029] The lower baking trays are all detachably arranged, facilitating users to replace different types of baking trays (such as flat-bottomed trays, corrugated trays, etc.) according to actual needs, meeting diversified cooking needs. In addition, the detachable design facilitates removal and cleaning, ensuring the cleanliness and long-term use of the device.

[0030] The upper baking tray is below the upper heating pipe, and the lower baking tray is above the lower heating pipe, which can be used to bake different types of food materials respectively. By combining the use of the upper and lower heating pipes and the baking trays, multi-layer baking, clamping heating, independent heating, and other multifunctional cooking modes can be realized, significantly expanding the use of the oven.

[0031] In combination with the independent or joint work of the upper and lower heating devices, users can choose to bake individually, clamp and heat from top to bottom, or bake in multiple layers according to needs. For example, when baking a cake, it can be heated from top to bottom at the same time, and when making a sandwich, it can be heated from top to bottom, greatly enriching the cooking scene.

[0032] The second object of the utility model is achieved in that:

[0033] An oven includes a cabinet, a cabinet door, and a handle. The cabinet door is hinged to the cabinet. The heating device is arranged in the cabinet. The handle is arranged on the outer wall of the cabinet. One end of the handle extends into the cabinet to connect the corresponding lifting device. The handle drives the lifting device to act. The lifting device drives the lower heating device to lift.

[0034] The handle is designed to be directly exposed to the outer wall of the cabinet. Users can operate the lifting device through the handle without opening the cabinet door, simplifying the use steps and improving the convenience of adjustment.

[0035] The linkage design of the handle and the lifting device enables users to accurately control the lifting height of the lower heating device through the handle action, thereby flexibly adjusting the heating position according to the needs of food materials and improving the controllability of cooking effect.

[0036] The lifting function of the lower heating device enables it to approach or move away from the food materials, achieving the purpose of efficient heating or slow baking. The flexible adjustment of the heat source position not only improves the thermal efficiency but also reduces the cooking time, enhancing the practicality of the device.

[0037] The handle and the lifting device are connected through internal and external connection design, occupy smaller space, do not cause interference to the structure inside or outside the oven, and ensure the overall aesthetics and space utilization of the oven.

[0038] The adjustable lower heating device can adjust the heating distance according to the position and thickness of the food material, effectively avoid overheating or uneven heating problems, and significantly improve the cooking quality and food taste.

[0039] The user can operate the lifting device through the handle when the cabinet door is closed, avoid direct contact with the high-temperature area inside, reduce the risk of scalding or accidents during cooking, and improve the safety performance of the equipment.

[0040] The beneficial effects of the utility model are as follows:

[0041] The utility model discloses a lower heating device is connected with the shell through the lifting device, can flexibly adjust the position of the heating device according to the height requirement of the food material, realizes the dynamic adjustment of the cooking space height.Thus can meet the close-range heating required by the thinner food material, and can also adapt to the larger cooking space required by the thicker food material.

[0042] The utility model discloses the height of the lower heating device is adjusted, and the user can optimize the distance between the food material and the heating device, so that the heat energy is more concentratedly applied to the surface of the food material, heat loss is reduced, and cooking efficiency is improved.More accurate heating distance can also avoid uneven heat distribution, and improve the heating effect of the food material.

[0043] The utility model discloses that the lifting support realizes the lifting function through the rotation of the first support and the second support, and the design is simple and convenient to operate.The user only needs to adjust the angle of the support to realize the height adjustment of the lower heating device, and does not need complex mechanical devices or redundant operation steps.
