Technical Field
[0001] The utility model belongs to the technical field of box-type ovens, and in particular relates to an energy-saving box-type oven. Background Art
[0002] In the processing of optoelectronics, electronics, motors, communications, electroplating, plastics, mechanical equipment and other industries, it is often necessary to spray various functional films on the surface of some parts. In order to speed up the combination of the film and the parts, the staff will use a box-type oven to heat and dry the coating.
[0003] At present, when existing energy-saving box-type drying ovens dry internal parts, the hot air will automatically move upward, resulting in the lower storage trays being heated lower than the upper storage trays. It is impossible to ensure that each layer of storage trays and the items in the trays are heated evenly, and multiple drying is required.
[0004] Therefore, in order to address the problem that the existing energy-saving box-type oven cannot ensure that the items in each layer of the storage tray can be heated evenly, resulting in the need for multiple dryings and low efficiency, the existing energy-saving box-type oven is improved so that hot air can be transported to each layer to ensure that each layer is heated evenly. Utility Model Content
[0005] In order to overcome the problem that the existing energy-saving box-type ovens cannot ensure that the items in each layer of the storage tray are evenly heated, resulting in low efficiency of the box-type ovens.
[0006] The technical solution of the utility model is: an energy-saving box-type drying oven, comprising a drying box, a box cover, a storage tray, a sliding component, a hot air supply component, and a waste heat recovery component; the box cover is movably connected to the front side of the drying box, a storage tray with a storage groove on the surface is provided in the drying box, and items to be dried are placed in the storage groove, a sliding component for moving the storage tray is provided in the drying box, a hot air supply component is provided on the left side of the drying box, and a waste heat recovery component is installed on the right side of the drying box.
[0007] Preferably, a hot air supply component is arranged above each layer of storage trays to provide hot air for each layer, thereby ensuring that the storage trays and items on each layer are heated evenly, thereby improving the drying efficiency of the energy-saving box-type drying oven. The waste heat recovery component can recycle the air with waste heat, thereby achieving energy-saving effects.
[0008] Preferably, the front side of the drying box is movably connected to a box cover by a hinge, and an observation window with embedded transparent glass is provided on the box cover. A handle is fixedly connected to the box cover, and the condition inside the drying box can be observed through the observation window. Since each layer provides consistent hot air, the observation window does not need to be too large, and the condition of other layers can be inferred by observing the condition of items on one layer.
[0009] Preferably, the sliding assembly includes slide rails and slide grooves; five slide rails are fixedly connected in the drying box, which are opposite to each other on the left and right and equidistantly arranged from top to bottom, and slide grooves are provided on the surfaces of the slide rails. The slide rails support the storage tray to prevent the storage tray from falling due to collision when moving the storage tray.
[0010] Preferably, the sliding assembly also includes a slider; a slider is slidably connected in the slide groove, and a storage tray is fixedly connected between the left and right sliders. The position of the storage tray fixedly connected to the slider in the drying box is changed by moving the slider in the slide groove.
[0011] Preferably, the hot air supply component includes a heating box and a hot air duct; a heating box with multiple groups of heating wires installed inside is installed on the left side of the drying box, an insulation board is bonded inside the heating box, and seven hot air ducts are arranged equidistantly from left to right and plugged into the drying box above each layer of slide rails. The heating box can heat the air and transport the hot air to the drying box through the hot air ducts. A hot air duct is installed above each layer of the storage tray, which can ensure that the same hot air is supplied to each layer and that each layer is heated evenly.
[0012] Preferably, the hot air supply component also includes an air outlet and a blower; each hot air pipe is provided with an air outlet located above the storage slot at the bottom end, and a blower is installed on the left side of the heating box. The hot air in the hot air pipe flows out from the air outlet, contacts the items in the storage slot, and converts the moisture in the items into water vapor through heating, so that it is separated from the objects themselves. The blower is responsible for introducing air into the heating box.
[0013] Preferably, the waste heat recovery component includes a condensation box and a circulating air duct; a condensation box for collecting condensed water is installed on the right side of the drying box, and a circulating air duct is inserted between the condensation box and the heating box. The condensation box is used to collect condensed water, which can be used later to reduce the waste of water resources. The circulating air duct sends the air with waste heat into the heating box. Since the waste heat air itself has a certain temperature, the heating time is shortened, which has an energy-saving effect.
[0014] Beneficial effects of the utility model:
[0015] 1. By improving the integrated hot air supply component of the original energy-saving box-type drying oven, a hot air pipe with an air outlet facing the lower storage slot is inserted on the storage tray of each layer, ensuring that the same hot air enters the drying box on each layer. The storage tray can limit the upward flow of hot air, ensuring that each layer is heated evenly and preventing the temperature of the bottom layer from being too low;
[0016] 2. When the hot air in the drying box passes through the condensing box, the temperature drops and the water vapor inside turns into liquid again and is collected in the condensing box, while the wind with waste heat enters the heating box through the circulating air duct. Since the wind contains waste heat, the heating time is shortened, which achieves an energy-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] See also Figure 1-2 The utility model provides an embodiment: an energy-saving box-type drying oven comprises a drying box 1, a box cover 2, a storage tray 3, a sliding component, a hot air supply component, and a waste heat recovery component; the drying box 1 is movably connected to the box cover 2 on the front side, a storage tray 3 with a storage groove on the surface is arranged in the drying box 1, and the items to be dried are placed in the storage groove, a sliding component for moving the storage tray 3 is arranged in the drying box 1, a hot air supply component is arranged on the left side of the drying box 1, and a waste heat recovery component is installed on the right side of the drying box 1. By arranging a hot air supply component above each layer of the storage tray 3, hot air is provided for each layer, ensuring that the storage tray 3 of each layer and the items in the tray can be heated evenly, thereby improving the drying efficiency of the energy-saving box-type drying oven, and the waste heat recovery component can recycle the wind with waste heat, thereby achieving energy-saving effect.
[0026] See also Figure 3-4In this embodiment, the front side of the drying box 1 is movably connected to a box cover 2 through a hinge, and an observation window 4 with a transparent glass embedded in the box cover 2 is provided. A handle 5 is fixedly connected to the box cover 2, and a sliding assembly includes a slide rail 601 and a slide groove 602; five slide rails 601 that are opposite to each other and arranged equidistantly from top to bottom are fixedly connected in the drying box 1, and a slide groove 602 is provided on the surface of the slide rail 601. The sliding assembly also includes a slider 603; a slider 603 is slidably connected in the slide groove 602, and a slider 603 is fixed between the left and right sliders 603. A storage tray 3 is connected, and the condition inside the drying box 1 can be observed through the observation window 4. Since each layer provides consistent hot air, the observation window 4 does not need to be too large. It is only necessary to observe the condition of one layer of items to obtain the condition of other layers. The slide rail 601 supports the storage tray 3 to prevent the storage tray 3 from falling due to collision when moving the storage tray 3. The position of the storage tray 3 fixedly connected to the slide rail 603 in the drying box 1 is changed by moving the slider 603 in the slide groove 602.
[0027] See also Figure 5-6 In this embodiment, the hot air supply component includes a heating box 701 and a hot air pipe 702; a heating box 701 with multiple groups of heating wires installed inside is installed on the left side of the drying box 1, and an insulation board is bonded inside the heating box 701. Seven hot air pipes 702 are arranged equidistantly from left to right and plugged into the drying box 1 above each layer of slide rails 601. The hot air supply component also includes an air outlet 703 and a blower 704; an air outlet 703 located above the storage slot is opened at the bottom of each hot air pipe 702, a blower 704 is installed on the left side of the heating box 701, and the waste heat recovery component includes a condensation box 801 and a circulating air pipe 802; a condensation box 801 for collecting condensed water is installed on the right side of the drying box 1, and a circulating air pipe 80 is plugged between the condensation box 801 and the heating box 701. 2. The heating box 701 can heat the wind and transport the hot wind to the drying box 1 through the hot air duct 702. A hot air duct 702 is installed above each layer of the storage tray 3 to ensure that the same hot air is supplied to each layer and that each layer is heated evenly. The hot air in the hot air duct 702 flows out from the air outlet 703 and contacts the items in the storage slot. The moisture in the items is converted into water vapor by heating to separate them from the objects themselves. The blower 704 is responsible for introducing the wind into the heating box 701. The condensation box 801 is used to collect condensed water, which can be used later to reduce the waste of water resources. The circulating air duct 802 sends the wind with waste heat into the heating box 701. Since the waste hot air itself has a certain temperature, the heating time is shortened, which has an energy-saving effect.
[0028] When working, the worker first places the articles to be dried into the storage slots of the storage tray 3, holds the handle 5 to open the cover door, and then chooses the optimal number of storage trays 3 to be placed in the drying box 1 according to the size and height of the articles to be dried, and then aligns the slider 603 with the slide slot 602 to push the storage tray 3 into the drying box 1, and then closes the cover door and observes the internal situation through the observation window 4;
[0029] The blower 704 is started, and the blower 704 blows air into the heating box 701. The heating wire in the heating box 701 heats the air to increase the air temperature. The heat preservation plate in the heating box 701 can prevent heat loss. After heating for a period of time, the heated hot air is transported to the drying box 1 through the hot air pipe 702. The hot air flows out from the air outlet 703 opened on the hot air pipe 702 and contacts the items in the storage slot. The hot air turns the moisture in the items into water vapor when heated and leaves the items, thereby achieving a drying effect.
[0030] The hot air in the drying box 1 flows into the condensing box 801. After a period of cooling, the water vapor returns to liquid and remains in the condensing box 801, waiting for subsequent use to avoid waste. The wind with residual heat enters the heating box 701 through the circulating air duct 802. Since the wind still carries residual heat, the time for heating to the corresponding temperature is shortened, which achieves an energy-saving effect.
[0031] Through the above steps, the integrated hot air supply component of the original energy-saving box-type drying oven is improved, and a hot air pipe 702 with an air outlet 703 aimed at the lower storage slot is inserted on the storage tray 3 of each layer, so as to ensure that the same hot air enters the drying box 1 on each layer, and the storage tray 3 can limit the upward flow of hot air to ensure that each layer is heated evenly and prevent the temperature of the bottom layer from being too low, so as to solve the problem that the existing energy-saving box-type drying oven cannot ensure that the items in each layer of the storage tray 3 are heated evenly, resulting in low efficiency of the box-type drying oven.
[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
