Description

Technical Field

[0001] This utility model relates to the technical field of fruit and vegetable dryers, and in particular to a parallel air-feeding fruit and vegetable dryer. Background Technology

[0002] Parallel air-blowing fruit and vegetable dryers are commonly used drying equipment for fruits and vegetables. Chinese utility model patent CN209106119U discloses a parallel air-blowing fruit and vegetable dryer. This dryer includes a casing with hinged doors on both sides of the front. Handles are fixed near the doors, with one handle connected to a limiting pin via a fixed shaft. Several sets of support frames are symmetrically arranged on both sides inside the casing, with limiting clips fixed above the support frames. Diverter pipes are embedded inside the limiting clips. This parallel air-blowing fruit and vegetable dryer facilitates closing the casing by providing doors, opening and closing by providing handles, closing by providing limiting pins, supporting the drying screen by providing support for drying the fruits and vegetables, and heating the air by providing an air heater. The air is then delivered to each diverter pipe through an air guide pipe, and the diverter pipes spray the air out through nozzles, accelerating the circulation of hot air inside the casing and ensuring more even heating of the fruits and vegetables.

[0003] However, the aforementioned dryer does not have an automatic shut-off function for the horizontal air supply mechanism. After the fruits and vegetables on the screen are dried, the corresponding air nozzles continue to supply air, resulting in wasted hot air and high energy consumption. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a parallel air supply fruit and vegetable dryer that can automatically close the corresponding air outlet when the fruits and vegetables on the fruit and vegetable tray are being dried, thereby reducing hot air waste and reducing energy consumption.

[0005] This utility model discloses a parallel air-feeding fruit and vegetable dryer, comprising a drying chamber, a hot air blower, and multiple air outlets. The drying chamber has a drying cavity inside, and a door communicating with the drying cavity is located on the front side of the drying chamber. The hot air blower has multiple air outlets, all extending into the left side of the drying cavity. It also includes multiple columns, multiple trays, multiple springs, multiple contact switches, and multiple contact arms. The columns are vertically installed in the drying cavity, and the trays are slidably connected to the columns. The trays are arranged horizontally vertically. Each spring is aligned with multiple air outlets. The lower ends of each spring are connected to multiple uprights, and the upper ends of each spring are connected to multiple trays. Multiple contact switches are mounted on the uprights, each with a contact arm. The ends of the contact arms are aligned with the upper surfaces of the trays. Each air outlet has an opening and closing assembly, which is electrically connected to the contact switches. During operation, fruit and vegetable trays of a certain weight are placed on the trays. The weight of the trays presses the trays downwards, causing the springs to... Once compressed, multiple contact arms disengage from multiple trays. Adjusting the positions of multiple contact switches ensures appropriate spacing between the contact arms and trays. Closing the drying oven door allows the hot air blown horizontally into the drying chamber through multiple outlets, drying the fruits and vegetables in the trays. As the fruits and vegetables are gradually dried, the weight of the trays decreases, and the elasticity of multiple springs supports the trays as they rise. When one tray... When the fruits and vegetables in the tray are dried, the tray plate under the fruit and vegetable tray rises and contacts the contact arm, thereby generating an electrical signal from the contact switch. The electrical signal is sent to the corresponding opening and closing component, which closes the corresponding air outlet while the other air outlets continue to supply air. When all air outlets are closed by the opening and closing components, the fruits and vegetables on all the fruit and vegetable trays are dried, the hot air blower is turned off, and the door is opened to remove the multiple fruit and vegetable trays. Compared with the existing technology, after the fruits and vegetables on a certain fruit and vegetable tray are dried, the corresponding air outlet automatically closes, thereby reducing hot air waste and reducing energy consumption.

[0006] Preferably, it also includes a slide groove and multiple sliders. The slide groove is vertically mounted on the column, and the multiple sliders are respectively mounted on the slide groove in a liftable manner. Multiple contact switches are respectively mounted on the multiple sliders. The multiple contact switches are respectively mounted on the slide groove via the multiple sliders. The multiple sliders slide and rise along the slide groove, thereby facilitating the adjustment of the relative height between the multiple contact switches and the multiple trays, which is suitable for fruit and vegetable trays of different weights.

[0007] Preferably, the device further includes multiple locking components, each mounted on a separate slider. These locking components lock the sliders onto the slide groove. Each locking component includes a sleeve, a push rod, a slide rod, and a second spring. The sleeve is mounted on the slider, the push rod is slidably inserted into the sleeve, and a slanted slide groove is provided on the side wall of the sleeve. The slide rod is mounted on the outer wall of the push rod and slidably installed in the slanted slide groove of the sleeve. One end of the second spring is connected to the sleeve, and the other end is connected to the push rod. The spring force of the second spring causes the inner end of the push rod to contact the slide groove. When the height position of the contact switch needs to be adjusted, the push rod is rotated, causing the slide rod to move along the slanted slide groove of the sleeve towards the outer end of the push rod. This causes the slide rod to move the push rod towards the outer end of the sleeve, disengaging the inner end of the push rod from the slide groove. This allows the slider to adjust its position along the slide groove. Releasing the push rod causes the spring force of the second spring to push the push rod towards the slide groove, pressing the push rod against the slide groove and locking the slider onto the slide groove. The operation is simple.

[0008] Preferably, the opening and closing assembly includes a cover plate, a swing arm, and a push cylinder. The swing arm is mounted on the end of the cover plate and is rotatably connected to the air outlet. The fixed end of the push cylinder is mounted on the air outlet, and the piston rod of the push cylinder is rotatably connected to the middle of the swing arm. The controller of the push cylinder is electrically connected to a contact switch. During drying, the piston rod of the push cylinder extends and pushes the swing arm outward toward the air outlet, causing the swing arm to drive the cover plate outward toward the air outlet, thus opening the air outlet. When the controller of the push cylinder receives an electrical signal from the contact switch, the piston rod of the push cylinder retracts and pulls the swing arm inward toward the air outlet, causing the swing arm to drive the cover plate outward toward the air outlet, thus closing the air outlet. The structure is simple and practical.

[0009] Preferably, it also includes multiple air guide plates, which are respectively installed on the lower end surface of multiple trays, with the lower ends of the multiple air guide plates facing multiple air outlets; the multiple air guide plates guide the hot air upward, so that the hot air passes through the multiple trays from bottom to top, and performs vertical air blowing and drying on the fruits and vegetables on the multiple fruit and vegetable trays, thereby improving the drying efficiency.

[0010] Preferably, it also includes multiple magnetic blocks, with multiple magnetic blocks installed on multiple trays; the multiple magnetic blocks are used to attach multiple fruit and vegetable trays to the multiple trays respectively, thereby improving the stability of the fruit and vegetable trays.

[0011] Preferably, the device also includes an air-concentrating hood, a horizontal air duct, an air outlet pipe, and a fan. The air-concentrating hood is vertically installed on the right side of the drying chamber of the drying oven. The air-concentrating hood has air inlets facing multiple air outlets. The horizontal air duct is horizontally installed at the top of the drying chamber of the drying oven. The right end of the horizontal air duct is connected to the upper end of the air-concentrating hood. An air outlet pipe is installed at the upper left end of the horizontal air duct and is connected to the horizontal air duct. The upper end of the air outlet pipe extends out of the top of the drying oven. The fan is installed in the air outlet pipe. The hot air horizontally delivered by the multiple air outlets dries the fruits and vegetables and then enters the air inlet of the air-concentrating hood. When the fan runs, the hot air containing a large amount of moisture is discharged through the air outlet pipe, the horizontal air duct, and the air-concentrating hood. By setting the horizontal air duct at the top of the drying chamber of the drying oven, the air in the horizontal air duct is heated and then discharged through the air outlet pipe, so that the hot and humid air can be discharged smoothly even when the fan is off.

[0012] Compared with the prior art, the beneficial effects of this utility model are: after the fruits and vegetables on a certain fruit and vegetable tray are dried, the corresponding air outlets are automatically closed, thereby reducing hot air waste and reducing energy consumption.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0016] like Figures 1 to 7 As shown, a parallel-flow fruit and vegetable dryer includes a drying chamber 1, a hot air blower 2, and multiple air outlets 3. The drying chamber 1 has a drying chamber inside, and a door communicating with the drying chamber is located on the front side of the drying chamber 1. The hot air blower 2 has multiple air outlets, all extending into the left side of the drying chamber 1. The dryer also includes multiple columns 4, multiple trays 5, multiple springs 6, multiple contact switches 7, and multiple contact arms 8. The columns 4 are vertically installed in the drying chamber 1, and the trays 5 are respectively connected to the columns 4. The system includes a sliding connection, multiple trays 5 arranged horizontally vertically, each tray 5 aligned with a multiple air outlet 3, multiple springs 6 connected at their lower ends to multiple columns 4, and multiple springs 6 connected at their upper ends to multiple trays 5, multiple contact switches 7 mounted on the columns 4, each contact switch 7 equipped with a contact arm 8, the ends of which are aligned with the upper surfaces of the multiple trays 5, and multiple air outlets 3 equipped with opening and closing components electrically connected to the multiple contact switches 7; it also includes a sliding groove 9 and multiple... The slider 10 and the slide groove 9 are vertically mounted on the column 4. Multiple sliders 10 are mounted on the slide groove 9 in a height-adjustable manner. Multiple contact switches 7 are mounted on the multiple sliders 10. The system also includes multiple locking assemblies, each mounted on a slider 10. Each locking assembly is used to lock the slider 10 onto the slide groove 9. Each locking assembly includes a sleeve 11, a push rod 12, a slide rod 13, and a spring 14. The sleeve 11 is mounted on the slider 10, and the push rod 12 is slidably inserted into the sleeve 11. An oblique sliding surface is provided on the side wall of the sleeve 11. The sleeve 11 has a groove, and a sliding rod 13 is installed on the outer wall of the top rod 12. The sliding rod 13 is slidably installed in the inclined groove of the sleeve 11. One end of the second spring 14 is connected to the sleeve 11, and the other end of the second spring 14 is connected to the top rod 12. The elastic force of the second spring 14 causes the inner end of the top rod 12 to contact the groove 9. The sleeve 12 also includes multiple air guide plates 18, which are respectively installed on the lower end surfaces of multiple support plates 5. The lower ends of the multiple air guide plates 18 all face the multiple air outlets 3. The sleeve 12 also includes multiple magnetic blocks 19, which are installed on the multiple support plates 5.

[0017] Multiple contact switches 7 are mounted on the slide groove 9 via multiple sliders 10. When the height of the contact switch 7 needs to be adjusted, the push rod 12 is rotated, causing the slide rod 13 to move along the inclined slide groove of the sleeve 11 towards the outer end of the push rod 12. This causes the slide rod 13 to drive the push rod 12 towards the outer end of the sleeve 11, disengaging the inner end of the push rod 12 from the slide groove 9. This allows the slider 10 to be adjusted along the slide groove 9. When the push rod 12 is released, the elastic force of the spring 14 pushes the push rod 12 towards the slide groove 9, pressing the push rod 12 against the slide groove 9, thereby locking the slider 10 onto the slide groove 9.

[0018] During operation, fruit and vegetable trays with a certain weight are placed on multiple trays 5. Multiple magnetic blocks 19 are used to attach the fruit and vegetable trays to the trays 5. The weight of the fruit and vegetable trays presses the trays 5 downward, compressing multiple springs 6. At this time, multiple contact arms 8 disengage from the trays 5. The positions of multiple contact switches 7 are adjusted to ensure a suitable distance between the contact arms 8 and the trays 5. The door of the drying chamber 1 is closed, and the hot air blower 2 horizontally into the drying chamber of the drying chamber 1 through multiple air outlets 3. The hot air blows horizontally over the fruit and vegetable trays, and multiple air guides 18 guide the hot air upward, allowing the hot air to pass through the trays 5 from bottom to top, vertically drying the fruits and vegetables on the trays. The fruits and vegetables in the fruit and vegetable trays are dried. As the fruits and vegetables in the trays are gradually dried, the weight of the trays gradually decreases. The elasticity of multiple springs 6 supports the multiple trays 5 to gradually rise. When the fruits and vegetables in a tray are dried, the tray 5 under the tray rises and contacts the contact arm 8, thereby causing the contact switch 7 to generate an electrical signal. The electrical signal is sent to the corresponding opening and closing component, which closes the corresponding air outlet 3. Other air outlets 3 continue to supply air. When all air outlets 3 are closed by the opening and closing component, the fruits and vegetables on all the trays are dried, the hot air blower 2 is turned off, the door is opened, and multiple fruit and vegetable trays are taken out. Compared with the existing technology, after the fruits and vegetables on a certain tray are dried, the corresponding air outlet 3 automatically closes, thereby reducing hot air waste and reducing energy consumption.

[0019] It also includes a concentrator hood 20, a cross air duct 21, an air outlet duct 22, and a fan 23. The concentrator hood 20 is vertically installed on the right side of the drying chamber of the drying box 1. The concentrator hood 20 has air inlets facing multiple air outlets 3. The cross air duct 21 is horizontally installed on the top of the drying chamber of the drying box 1. The right end of the cross air duct 21 is connected to the upper end of the concentrator hood 20. The upper left end of the cross air duct 21 is provided with an air outlet duct 22, which is connected to the cross air duct 21. The upper end of the air outlet duct 22 extends out of the top of the drying box 1. The fan 23 is installed in the air outlet duct 22.

[0020] The hot air delivered horizontally by multiple air outlets 3 dries the fruits and vegetables and then enters the air inlet of the concentrator hood 20. The fan 23 runs and discharges the hot air containing a large amount of moisture through the air outlet duct 22, the cross air duct 21 and the concentrator hood 20. By setting the cross air duct 21 at the top of the drying chamber of the drying box 1, the air in the cross air duct 21 is heated and then discharged through the air outlet duct 22, so that the hot and humid air can be discharged smoothly even when the fan 23 is turned off. Example 2

[0021] like Figure 2 and Figure 6 As shown, based on Embodiment 1, the opening and closing assembly includes a cover plate 15, a swing arm 16, and a push cylinder 17. The end of the cover plate 15 is equipped with the swing arm 16, and the end of the swing arm 16 is rotatably connected to the air outlet 3. The fixed end of the push cylinder 17 is installed on the air outlet 3, and the piston rod of the push cylinder 17 is rotatably connected to the middle of the swing arm 16. The controller of the push cylinder 17 is electrically connected to the contact switch 7.

[0022] During drying, the piston rod of the push cylinder 17 extends, pushing the swing arm 16 outward towards the air outlet 3. This causes the swing arm 16 to drive the cover plate 15 outward towards the air outlet 3, thus opening the air outlet 3. When the controller of the push cylinder 17 receives an electrical signal from the contact switch 7, the piston rod of the push cylinder 17 retracts, pulling the swing arm 16 inward towards the air outlet 3. This causes the swing arm 16 to drive the cover plate 15 outward towards the air outlet 3, thus closing the air outlet 3. The structure is simple and practical.

[0023] like Figures 1 to 7As shown, this utility model discloses a parallel air-blowing fruit and vegetable dryer. During operation, fruit and vegetable trays with a certain weight are first placed on multiple trays 5. The weight of the trays presses the trays 5 downwards, compressing multiple springs 6. At this time, multiple contact arms 8 disengage from the trays 5. The positions of multiple contact switches 7 are adjusted to ensure a suitable distance between the contact arms 8 and the trays 5. The door of the drying chamber 1 is then closed. Afterwards, the hot air blower 2 runs through multiple air outlets 3, horizontally blowing hot air into the drying chamber of the drying chamber 1. This causes the hot air to blow horizontally across the multiple fruit and vegetable trays, thereby drying the fruits and vegetables in the trays. The fan 23 operates to remove water... The hot air is discharged through the air outlet duct 22, the cross air duct 21, and the air gathering hood 20. As the fruits and vegetables in the fruit and vegetable trays are gradually dried, the weight of the fruit and vegetable trays gradually decreases. The elasticity of multiple springs 6 supports the multiple trays 5 to gradually rise. When the fruits and vegetables in a fruit and vegetable tray are dried, the tray 5 under the fruit and vegetable tray rises and contacts the contact arm 8, thereby causing the contact switch 7 to generate an electrical signal. The electrical signal is sent to the corresponding push cylinder 17, causing the cover plate 15 to close the corresponding air outlet 3. Other air outlets 3 continue to supply air. Finally, when all air outlets 3 are closed by the cover plate 15, the fruits and vegetables on all fruit and vegetable trays are dried, the hot air blower 2 is turned off, and the box door can be opened to remove the multiple fruit and vegetable trays.

[0024] The main functions achieved by this utility model are: 1. When the fruits and vegetables on the fruit and vegetable tray are being dried, the corresponding air outlet 3 can be automatically closed, thereby reducing hot air waste and reducing energy consumption; 2. The distance between the contact switch 7 and the tray 5 can be flexibly adjusted to accommodate fruit and vegetable trays of different weights, making it highly versatile; 3. It can vertically guide airflow to the fruit and vegetable tray, improving drying efficiency.

[0025] The parallel air-blowing fruit and vegetable dryer of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired beneficial effect can be implemented. The drying box 1, hot air blower 2, air outlet 3, support plate 5, spring 1 6, contact switch 7, contact arm 8, slide 9, slider 10, spring 2 14, push cylinder 17, magnetic block 19, and fan 23 of this parallel air-blowing fruit and vegetable dryer are commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
