Description

Technical Field

[0001] This application relates to the technical field of oven devices, and more specifically, to an oven device. Background Art

[0002] In the prior art, an oven often uses a heat source such as a heating lamp tube to generate heat to provide the temperature required by the oven. In order to evenly transfer the heat of the heat source, a blower is usually equipped, so that the heat of the heat source can be driven to the material to be dried through the flowing air. However, although the blower can transfer and disperse the heat and avoid a large amount of energy consumption, there are still certain defects. For example, when using an ordinary natural blower to operate, since the heat source has a heating process before reaching the predetermined temperature and the natural wind is usually at a relatively low temperature, common ovens often cannot enter the drying state at the initial startup stage, or the drying effect is not good at the initial stage.

[0003] Therefore, there is an urgent need in the prior art for an oven device that retains the advantages of energy consumption while solving the problem of poor drying effect during the heating process. Summary of the Invention

[0004] This application aims to overcome at least one of the above-mentioned deficiencies in the prior art, and provides an oven device with a simple structure, taking into account the operating efficiency and energy consumption of the oven.

[0005] The technical solution adopted by this application is an oven device, including: a unit box body, a suction device, and a hot air pipe. A first cavity is formed in the unit box body. A heat source is arranged on the lower side of the box body. The suction device and the hot air pipe are communicated with the heat source through the first cavity. The suction device and the hot air pipe work alternately. When the heat source is still in the heating state, starting the hot air pipe that provides hot air can quickly provide hot air corresponding to the temperature requirement, so as to immediately reach the drying temperature requirement. When the heat source rises to the expected temperature, at this time, the hot air pipe is switched to the suction device, and the inhaled natural wind can cooperate with the heat source to generate hot air corresponding to the temperature requirement, so as to continuously carry out the subsequent oven treatment in production. And because the heating time of the heat source is short, the suction device with relatively low energy consumption can be started after briefly starting the hot air pipe. The overall oven has low energy consumption in air flow and will not cause a serious increase in energy consumption. At the same time, two different wind force mechanisms are set, which is convenient for immediate switching, quickly raising the operating temperature of the oven and balancing the thermal cost and heating efficiency; significantly improving the oven efficiency.

To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0026] The technical solutions of this application will be clearly and completely described below in conjunction with the attached drawings and specific implementation modes. However, those skilled in the art will understand that the described embodiments are some embodiments of this application, rather than all embodiments, and are only used to illustrate this application and should not be regarded as limiting the scope of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. Embodiment 1

[0027] As Figures 1 - 2 shown, this embodiment discloses an oven device 1000, including: unit box 1100, air suction device 1300, hot air duct 1200. A first cavity 1160 is formed inside the unit box 1100. A heat source 1164 is arranged on the lower side of the box body. The air suction device 1300 and the hot air duct 1200 communicate with the heat source 1164 through the first cavity 1160. Specifically, the hot air duct 1200 and the air suction device 1300 are both arranged on the upper side of the unit box 1100. The hot air duct 1200 is connected with a hot air blower structure. And there are two hot air ducts 1200 arranged on the unit box 1100. The air suction device 1300 is arranged in the middle of the box body unit. The hot air ducts 1200 are symmetrically arranged on both sides of the air suction device 1300. To improve the diffusion of the introduced air in the horizontal direction and ensure the acting area, in this embodiment, the pipe wall of the hot air duct 1200 on one side of the first cavity 1160 is provided with a plurality of air outlet holes.

[0028] In this embodiment, a plurality of heat sources 1164 are arranged on the lower side of the box body. The heat sources 1164 are heating tubes, and in the material feeding direction, the plurality of heating tubes are arranged in an arc shape; that is, in the cross-section of the oven, the plurality of heating tubes form an arc structure. Specifically, in terms of the type of heating tube, the long strip-shaped heating lamp tubes are adopted in this embodiment, which is beneficial to simplifying the structure and installation. In addition, the heat source 1164 can also be an entire heating panel, etc.

[0029] The unit box body 1100 includes an upper cover plate 1110, first baffles 1120 on the front and rear sides, and second baffles 1130 on the left and right sides. A partition plate 1150 is further provided in the unit box body 1100, and the partition plate 1150 divides the interior of the box body into a second cavity 1140 on the upper side and a first cavity 1160 below the second cavity 1140. The second cavity 1140 is at least used for filling heat insulation materials. The heat insulation materials include heat insulation cotton, which can reduce the heat loss of the staying hot air when the introduced air volume is large and the introduced air conducts heat with the heat source 1164. In addition, in order to adapt to the arc-shaped arrangement of the foregoing heating tubes, the lower side of the second baffle 1130 is an arc structure protruding upward. Local lower cover plates 1165 can also be provided at the bottoms of both ends of the oven device 1000, as Figure 7 shown, which is convenient for forming a stable heat baking area.

[0030] As Figures 2 - 6 shown, in order to improve the effect of the introduced air, a flow disturbing plate 1162 is further provided in the first cavity 1160 of the unit box body 1100. The flow disturbing plate 1162 divides the first cavity 1160 into an upper cavity 1161 and an installation cavity 1163 below the upper cavity 1161. The installation cavity 1163 is a cavity with a downward opening. A plurality of ventilation holes 1162A are provided on the flow disturbing plate 1162, and the heat source 1164 is installed on the installation cavity 1163. The air suction device 1300 and the hot air pipe 1200 are communicated with the heat source 1164 in the installation cavity 1163 through the upper cavity 1161 and the ventilation holes 1162A. When the air suction device 1300 or the hot air pipe 1200 guides air into the first cavity 1160, the flow disturbing plate 1162 forms a barrier, so that the introduced air flows and spreads on the flow disturbing plate 1162, and then the introduced air is discharged to the heat source side through the ventilation holes 1162A of the flow disturbing plate 1162. The ventilation openings on the flow disturbing plate 1162 are evenly distributed, and in this embodiment, they are evenly arranged in a matrix array. In addition, when the flow disturbing plate 1162 is provided, the upper cover plate 1110 and the flow disturbing plate 1162 are both arc-shaped plates.

[0031] The heating tube can be fixed on the flow disturbing plate 1162 through a heating tube mounting bracket and locked on the ventilation hole 1162A of the flow disturbing plate 1162.

[0032] In this embodiment, a handle structure 1133 is further provided on the second baffle 1130 on the outermost side of the oven device 1000, which facilitates the installation and maintenance by the operator.

[0033] As Figures 1 - 2 shown, the oven device 1000 in this embodiment can be composed of multiple unit boxes 1100 as a whole. For example, it includes multiple unit boxes 1100 connected to each other in the length direction. The same second baffle 1130 is shared between adjacent unit boxes 1100. By connecting multiple unit boxes 1100, an oven with a wider width is formed, which is compatible with large-sized materials.

[0034] In order to cooperate with the arc-shaped workpiece for heat drying, the oven device 1000 may also need to be installed at a specific angle. Therefore, in this embodiment, an installation fixing seat 1131 is provided on the end side of the oven device 1000. The installation fixing seat 1131 at least includes an installation shaft 1131A; and, an angle fixing seat 1132 is also provided on the end side of the oven device 1000. The angle fixing seat 1132 cooperates with the installation fixing seat 1131 to fix the orientation angle of the bottom surface of the oven. Through the common positioning of the two structures of the installation fixing seat 1131 and the angle fixing seat 1132, the angle of the heat drying surface of the oven is fixed to cooperate with the arc-shaped structure and deployment. That is, an installation fixing seat 1131 is provided on the second baffle 1130 on the outermost side of the overall oven. The installation fixing seat 1131 at least includes an installation shaft 1131A; and, an angle fixing seat 1132 is also provided on the outermost second baffle 1130. The angle fixing seat 1132 cooperates with the installation fixing seat 1131 to fix the orientation angle of the bottom surface of the oven.

[0035] An example implementation principle: The air suction device 1300 and the hot air pipe 1200 switch to work. When the heat source 1164 is still in the heating-up state, starting the hot air pipe 1200 that provides hot air can quickly provide hot air corresponding to the temperature requirement, so as to immediately reach the drying temperature requirement; and when the heat source 1164 heats up to the expected temperature, at this time, the hot air pipe 1200 is switched to the air suction device 1300. The natural wind inhaled can cooperate with the heat source 1164 to generate hot air corresponding to the temperature requirement, so as to continuously carry out the subsequent oven treatment in production. And because the heating-up time of the heat source 1164 is short, the low-energy-consuming air suction device 1300 can be started after briefly starting the hot air pipe 1200. The overall oven consumes less energy in air flow and will not cause a serious increase in energy consumption. At the same time, two different wind force mechanisms are set, which is convenient for immediate switching, quickly raising the operating temperature of the oven and balancing the thermal cost and heating efficiency; significantly improving the oven efficiency.
