Description

Technical Field

[0001] This utility model relates to the field of drying ovens, and more particularly to an electronic blower drying oven. Background Technology

[0002] Electronic forced-air drying ovens are a type of general-purpose drying equipment widely used in industrial and agricultural production, scientific research, and medical and health fields. They use fans to force-circulate hot air to dry items. To improve drying efficiency, the oven is usually equipped with multiple shelves to process multiple batches or large volumes of items simultaneously.

[0003] However, existing drying ovens generally suffer from uneven drying in practical use. This is mainly because the hot airflow generated by the heating device is often concentrated, and when it blows directly into the interior of the oven, it cannot form a uniform airflow, resulting in some areas being too hot while others are too cold. More importantly, when items are placed on multiple shelves, the upper shelves and items severely obstruct the hot airflow, greatly hindering the hot air from reaching the lower layers. This makes the drying effect of items on the lower layers far less effective than those on the upper layers, seriously affecting the overall drying quality and reliability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electronic forced-air drying oven, which aims to improve the problem of uneven drying effect caused by the concentrated hot air flow and the physical obstruction of the upper shelf. This utility model aims to provide an electronic forced-air drying oven with an improved structure that can effectively solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic blower drying oven, comprising: a box body, a fan, a heating wire, and a placement plate; as well as a flow guiding assembly, a sliding frame, and a limiting assembly.

[0006] The airflow guiding component is used to homogenize the hot air from the heating wire.

[0007] Furthermore, the sliding frame is fixed vertically to the inner side wall of the box, the placement plate is slidably mounted on the sliding frame, the flow guiding component is disposed on the airflow side of the heating wire, and the limiting component acts on the sliding frame to fix the placement plate in a vertical position so that it can slide on the sliding frame.

[0008] Preferably, the flow guiding assembly includes a V-shaped plate, a flow splitter, and a flow guide plate in sequence along the airflow direction.

[0009] Preferably, the V-shaped plate includes two plates spaced apart in the vertical direction, which divide the internal space of the airflow guide assembly into three airflow regions: upper, middle, and lower.

[0010] Preferably, the diverter plate is a plate structure with multiple through holes, used to disperse the airflow after it has been divided by the V-shaped plate.

[0011] Preferably, the guide plate is an inclined plate used to guide the airflow dispersed by the diverter plate.

[0012] Preferably, the limiting assembly includes a limiting rod, a spring, a fixing block, and a connecting seat, wherein the limiting rod is pivotally connected to the housing via the connecting seat.

[0013] Preferably, the fixing block is provided with a slot, and the limiting rod is provided with a protrusion that cooperates with the slot; under the elastic force of the spring, one end of the limiting rod abuts against the sliding frame to achieve limiting.

[0014] Preferably, when the limiting rod is moved so that its protrusion engages in the slot of the fixing block, one end of the limiting rod disengages from the sliding frame to release the limiting action.

[0015] Preferably, the electronic blower drying oven further includes a first fixing plate and a second fixing plate, and the heating wire is disposed between the first fixing plate and the second fixing plate.

[0016] Preferably, the first fixing plate is disposed between the fan and the heating wire, and the second fixing plate is disposed between the heating wire and the flow guiding component.

In this utility model, by setting up a placement plate that can be freely adjusted in height by means of a sliding frame and a limiting component, the problem of uneven drying effect of multiple layers caused by the fixed position of the shelf and the physical obstruction of the hot air below by the items on the upper layer is solved.

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0022] Please refer to Figures 1 to 5 This utility model provides an electronic blower drying oven, which aims to solve the problem of inconsistent drying effect of items caused by uneven hot air distribution and physical obstruction by shelves in the prior art.

[0023] like Figures 1-5 As shown, the electronic blower drying oven includes a housing 1. Inside the housing 1, a fan 2, a first fixing plate 3, a heating wire 5, a second fixing plate 6, a flow guide assembly 4, a placement plate 7, a sliding frame 8, and a limiting assembly 9 are arranged. The fan 2 is fixedly connected to the rear inner wall of the housing 1. The first fixing plate 3 is fixed to the airflow outlet of the fan 2. The heating wire 5 is arranged between the first fixing plate 3 and the second fixing plate 6, with the second fixing plate 6 fixed downstream of the airflow from the heating wire 5. The flow guide assembly 4 is fixedly connected to one side of the airflow from the second fixing plate 6 to homogenize the hot air from the heating wire 5. The sliding frame 8 is fixed vertically to the inner wall of the housing 1, and the multi-layer placement plate 7 is mounted on the sliding frame 8 via a sliding fit. The limiting assembly 9 is mounted on the housing 1 and interacts with the sliding frame 8 to lock or release the placement plate 7.

[0024] Please refer to the following carefully. Figure 1 and Figure 3The flow guiding component 4 has a hollow structure, with its inlet end fixedly connected to the downstream side of the second fixed plate 6. Inside its internal cavity, a V-shaped plate 403, a flow divider 401, and a flow guide 402 are sequentially arranged along the airflow direction blown out by the fan 2. The V-shaped plate 403 comprises two plates spaced vertically apart, which forcibly divide the internal space of the flow guiding component 4 into three independent airflow regions: upper, middle, and lower, thus initially dividing the concentrated hot air from the heating wire 5. The flow divider 401 is a plate structure with multiple through holes, fixedly located downstream of the V-shaped plate 403. The three airflow streams divided by the V-shaped plate 403... The airflow continues to advance and passes through multiple through holes on the diverter plate 401. During the perforation process, the airflow is further dispersed and mixed, thereby achieving heat homogenization. The guide plate 402 is an inclined plate that is fixed at the downstream outlet of the guide assembly 4. It is used to perform final flow regulation on the already fully mixed uniform hot air and smoothly guide it to the entire drying area where the placement plate 7 is located. This multi-stage airflow processing structure, which consists of the V-shaped plate 403, the diverter plate 401 and the guide plate 402 connected in series, ensures that the hot air reaching the placement plate 7 has a highly uniform temperature and velocity distribution, providing a basis for achieving a consistent drying effect.

[0025] As a preferred embodiment, please refer to the following: Figure 4 and Figure 5 To provide the placement plate 7 with adjustable height, the electronic blower drying oven is equipped with a sophisticated limiting component 9. The limiting component 9 includes a limiting rod 901, a spring 902, a fixing block 903, and a connecting seat 904. The connecting seat 904 is fixed to the inner wall of the oven body 1, providing a stable rotation fulcrum for the limiting rod 901. The limiting rod 901 is pivotally connected to the connecting seat 904. The spring 902 connects the limiting rod 901 and the connecting seat 904, providing a reset force when no external force is applied, keeping the limiting rod 901 in its default locked position. The fixing block 903 is also fixed to the oven body 1 and has a slot for holding the limiting rod 901. The limiting rod 901... The upper part is provided with a protrusion that cooperates with the slot; in the default locked state, the limiting rod 901, under the elastic force of the spring 902, physically abuts against the sliding frame 8, thereby restricting the sliding frame 8 and the placement plate 7 it carries from sliding; when the height needs to be adjusted, the limiting rod 901 is moved to rotate around the connecting seat 904 and squeeze the spring 902 until the protrusion of the limiting rod 901 is engaged in the slot of the fixing block 903. At this time, the end of the limiting rod 901 is disengaged from the sliding frame 8, releasing the limitation on the sliding frame 8, and the placement plate 7 can slide freely; this mechanical structure is simple and reliable, easy to operate, and effectively solves the problem of airflow obstruction caused by the fixed position of the shelf.

[0026] As another preferred embodiment, please refer to Figure 2 and Figure 3 In order to effectively define the heating process area and provide a mounting base for related components, the electronic blower drying oven also includes a first fixing plate 3 and a second fixing plate 6; the two ends of the heating wire 5 are fixed respectively, so that the whole is arranged between the first fixing plate 3 and the second fixing plate 6 to form an independent heating area; the first fixing plate 3 is fixedly set between the fan 2 and the heating wire 5, and its plate body has through holes for airflow to pass through, which is used to support the heating wire 5 and to initially regulate the airflow from the fan 2; the second fixing plate 6 is fixedly set between the heating wire 5 and the flow guiding component 4, which is used to support the other end of the heating wire 5 and serve as the mounting base of the flow guiding component 4.

[0027] Working principle: When drying is required, the fan 2 starts to generate airflow. The airflow passes sequentially through the heating wire 5 between the first fixed plate 3 and the second fixed plate 6, and is heated into high-temperature drying hot air. The high-temperature hot air then enters the guide assembly 4, first passing through two vertically spaced V-shaped plates 403, where the concentrated hot air is forcibly divided into three independent airflows: upper, middle, and lower. These three airflows then continue flowing through the perforated distribution plate 401, where they are further dispersed and fully mixed. Finally, the inclined guide plate 402 smoothly guides the homogenized hot air towards the placement plate 7, achieving the desired drying effect. The entire drying area is evenly covered. If further optimization of drying uniformity is needed to adapt to different items, the limiting component 9 can be operated. By moving the limiting rod 901, it rotates around the connecting seat 904 and drives the protrusion to compress the spring 902 until the protrusion is inserted into the slot of the fixing block 903. At this time, one end of the limiting rod 901 disengages from the sliding frame 8, releasing the lock on the sliding frame 8. Then, the placement plate 7 can be pushed to slide up and down along the sliding frame 8 to freely adjust the spacing between each layer. This effectively avoids the upper placement plate 7 blocking the hot air below, ensuring that all items in the box 1 can receive a sufficient and uniform supply of hot air.
