[0002] With the vigorous development of modern industry and the continuous improvement of people's quality of life, the demand for drying of various products is becoming increasingly diversified. In many fields, such as food processing, electronic manufacturing, and scientific research experiments, ovens are needed to dry items. Portable ovens, due to their flexibility and convenience, are gradually emerging in these scenarios and their application scope is constantly expanding.

[0003] However, existing ovens are not easy to maintain and inspect. Dust and debris accumulate on their internal components over time, which affects the heat transfer of the device and causes uneven temperature distribution inside the oven. This can result in products being partially scorched or undercooked, reducing product quality and affecting production or usage. Utility Model Content

[0004] The purpose of this utility model is to provide a portable oven. By setting up an unfolding mechanism, it solves the problems of existing ovens being inconvenient to maintain and inspect, and the accumulation of dust and debris in their internal components due to long-term use, which affects the heat transfer of the device, causes uneven temperature distribution inside the oven, and results in localized scorching or undercooking of the baked products, reducing product quality and affecting production or usage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a portable drying oven, including a top plate of the oven, on which an unfolding mechanism and several locking mechanisms are provided;

[0007] The unfolding mechanism includes two outer side plates disposed at the bottom of the oven top plate. Each of the two outer side plates has two hinges on the side away from each other. The two outer side plates are hinged to the oven top plate through several hinges. An L-shaped outer side plate is disposed between the two outer side plates. Two connecting plates are disposed between the two L-shaped outer side plates. The locking mechanism includes a limiting block fixedly connected to the left side of the left L-shaped outer side plate.

[0008] Furthermore, a heat transfer plate is provided on the bottom inner wall of the two L-shaped outer side plates. The top of the heat transfer plate is fixedly connected to the top plate of the oven. The front and rear sides of the heat transfer plate are fixedly connected to two connecting plates respectively. Two heater elements are provided on the outer wall of the connecting plate.

[0009] Furthermore, a temperature controller is fixedly connected to the top of the oven top plate, and handles are fixedly connected to the two L-shaped outer side plates on opposite sides. A fixing block is fixedly connected to the front side of the L-shaped outer side plate, and the top and bottom of the fixing block are in contact with the limiting block. A fixing rod is fixedly connected to the front side of the L-shaped outer side plate.

[0010] Furthermore, a sliding rod passes through the fixed rod, a limiting block passes through the bottom of the sliding rod, the sliding rod is slidably connected to the limiting block, the sliding rod is slidably connected to the fixed block, and the sliding rod is slidably connected to the fixed rod.

[0011] Furthermore, a cylindrical groove is formed inside the fixed rod, a slider is fixedly connected to the outer wall of the sliding rod, the outer wall of the slider is slidably connected to the cylindrical groove, a spring is sleeved on the outer wall of the sliding rod, the top of the spring is fixedly connected to the fixed rod, the bottom of the spring is fixedly connected to the slider, and a button is fixedly connected to the top of the sliding rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up an unfolding mechanism, when inspection and maintenance are required, the four locking mechanisms can be opened, and the two L-shaped outer side panels can be pulled by the two handles to remove the two L-shaped outer side panels. Then, one side of the outer side panel can be rotated. The outer side panel is hinged to the top plate of the oven through a hinge, allowing the outer side panel to be rotated and opened. At this time, the heating element and heat transfer plate inside the device will be exposed, and they can be cleaned and maintained. The hinge can be used to move the device, and in conjunction with the locking mechanism, it can be disassembled and closed, which facilitates daily inspection and replacement of parts. This avoids the accumulation of dust and debris in the internal parts of the device due to long-term use, which affects the heat transfer of the device and causes uneven temperature distribution in the oven, resulting in local scorching or undercooking of the baked products.

[0014] 2. By setting up a locking mechanism, when unlocking one locking mechanism, the sliding rod is lifted by pressing the button, causing it to move away from the limit block. During this process, the slider will rise with the sliding rod, thereby compressing the spring and causing it to contract. After maintenance is completed, the two L-shaped outer side plates will reset. Releasing the button will cause the sliding rod to return to its original position with the spring, re-locking the device. This ensures that the L-shaped outer side plates are tightly fixed, preventing accidental opening and thus avoiding burns to operators due to accidental opening or damage to surrounding objects due to contact with high-temperature components.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Two connecting plates 214 are provided between the two L-shaped outer side plates 213. A heat transfer plate 215 is provided on the bottom inner wall of the two L-shaped outer side plates 213. The top of the heat transfer plate 215 is connected to the oven top plate. 1. Fixed connection: The front and rear sides of the heat transfer plate 215 are fixedly connected to two connecting plates 214 respectively. Two heating elements 216 are provided on the two outer walls of the connecting plates 214. A temperature controller 217 is fixedly connected to the top of the oven top plate 1. Handles 218 are fixedly connected to the two L-shaped outer side plates 213 on the opposite sides. By setting the unfolding mechanism 2, the hinge 212 can be used to move the device. With the cooperation of the mechanism locking mechanism 3, it can be disassembled and closed, which facilitates daily maintenance and replacement of parts. It avoids the accumulation of dust and debris in the internal parts of the device due to long-term use, which affects the heat transfer of the device and causes uneven temperature distribution in the oven. This can result in the baked products being locally scorched or undercooked.

[0026] The locking mechanism 3 includes a limiting block 311 fixedly connected to the left side of the left-side L-shaped outer side plate 213; a fixing block 312 fixedly connected to the front side of the front-side L-shaped outer side plate 213, with the top and bottom of the fixing block 312 in contact with the limiting block 311; a fixing rod 313 fixedly connected to the front side of the front-side L-shaped outer side plate 213; a sliding rod 314 passing through the fixing rod 313; the bottom of the sliding rod 314 passing through the limiting block 311; the sliding rod 314 slidably connected to the limiting block 311; the sliding rod 314 slidably connected to the fixing block 312; and the sliding rod 314 slidably connected to the fixing rod 313. A cylindrical groove 315 is provided inside the rod 313. A slider 316 is fixedly connected to the outer wall of the slide rod 314. The outer wall of the slider 316 is slidably connected to the cylindrical groove 315. A spring 317 is sleeved on the outer wall of the slide rod 314. The top of the spring 317 is fixedly connected to the fixed rod 313, and the bottom of the spring 317 is fixedly connected to the slider 316. A button 318 is fixedly connected to the top of the slide rod 314. By setting the locking mechanism 3, the L-shaped outer side plate 213 can be tightly fixed to prevent it from being opened accidentally, thereby avoiding the operator being burned by high temperature due to accidental opening, or the surrounding objects being damaged by contact with high temperature components.

[0027] One specific application of this embodiment is as follows: In use, because the device is designed with three sides closed and the bottom open, the product to be baked can be placed inside the oven to achieve localized heating and drying. This eliminates the need to place the entire product inside the oven for drying, allowing for a smaller size design. The device can be easily lifted using two handles 218 and placed over the object to be baked. The heating element 216 is controlled by the temperature controller 217 for heating and baking, achieving convenient use. For inspection and maintenance, the four locking mechanisms 3 are opened, and the two L-shaped outer side plates 213 can be pulled using the two handles 218 to remove them. Then, they can be rotated... One outer side plate 211 is hinged to the top plate 1 of the oven via a hinge 212, allowing the outer side plate 211 to rotate and open. At this time, the heating element 216 and heat transfer plate 215 inside the device will be exposed, and they can be cleaned and maintained. To unlock one of the locking mechanisms 3, the sliding rod 314 is lifted by pressing button 318, which moves it away from the limit block 311. During this process, the slider 316 will rise with the sliding rod 314, thereby squeezing the spring 317 and causing it to contract. After maintenance is completed, the two L-shaped outer side plates 213 are reset. Then, the button 318 is released, and the sliding rod 314 returns to its original position with the spring 317, locking the device again.
