[0002] Air source heat pump fruit and vegetable drying machine is an advanced drying device, which cleverly uses air source heat pump technology to absorb low-temperature heat energy from the surrounding environment and convert it into high-temperature heat energy to achieve efficient dehydration of fruits and vegetables. This process not only saves energy and reduces consumption, reduces the impact on the environment, but also can significantly improve drying quality and production efficiency, which is a major advancement in the field of modern agricultural product processing.

[0003] However, in actual applications, air source heat pump fruit and vegetable dryers also face some challenges. For example, after the drying operation is completed, the operator needs to manually pull the drying rack containing the dried fruits and vegetables out of the machine. Due to the high temperature generated by the drying process, the surface temperature of the drying rack is high, which may not only cause the risk of scalding to the operator, but also increase the work intensity because it requires greater physical labor. What's more complicated is that each dryer is usually equipped with multiple layers of drying racks. When it is necessary to collect the dried fruits and vegetables, the operator must disassemble and take out each layer of fruits and vegetables one by one. This process is time-consuming and laborious, which greatly affects work efficiency. Therefore, how to optimize the design and operation process of the drying rack and reduce the burden on staff has become one of the key points to further improve the performance of air source heat pump fruit and vegetable dryers.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0028] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides an air source heat pump fruit and vegetable drying machine that is easy to install, comprising a plurality of sets of mounting units 1 and two sets of driving units 2, and each set of mounting units 1 is driven by the driving units 2 on both sides thereof; Each set of erection units 1 includes a plurality of horizontally arrayed mesh panels 11, two sets of connecting members 12 disposed on both sides of each set of mesh panels 11, a slide plate 13 disposed on one side of the mesh panels 11, a first stopper 14 disposed on the connecting member 12, and a second stopper 15 disposed on the slide plate 13; The driving unit 2 includes an extension plate 21 disposed on the outside of the slide plate 13, a plurality of groups of protrusions 22 disposed on one side of the extension plate 21, an electromagnet 23 disposed on the inner side of each group of protrusions 22, and an electric push rod 24 disposed at the bottom of the extension plate 21; The first stopper 14 and the second stopper 15 both cooperate with the electromagnet 23 .

[0029] Furthermore, it also includes a box body 3, which includes a plurality of slide rails 31 arranged on its side wall and a placement box 32 arranged outside the box body 3; The slide rail 31 includes a spring piece 311 disposed at an end thereof and an escape groove 312 disposed at an outer side of the slide rail 31 .

[0030] Furthermore, the first stopper 14 and the second stopper 15 have the same structure.

[0031] Furthermore, the first stopper 14 includes a sleeve 141 disposed inside the limiting hole 12221, a telescopic cylinder 142 disposed inside the sleeve 141, and a magnetic surface 143 disposed on the end surface of the telescopic cylinder 142; A group of conical springs 16 are fixedly connected to the inner sides of the sleeve 141 and the telescopic cylinder 142 .

[0032] Furthermore, the extension board 21 includes a connection circuit 211 disposed on the inner side thereof, and a sub-controller 212 disposed on one side of the connection circuit 211; The sub-controller 212 can control the power supply of each electromagnet 23 separately.

[0033] Furthermore, the protrusion 22 includes a placement groove 221 disposed on an inner side thereof, and a stopper 222 disposed on one side of the placement groove 221 .

[0034] Furthermore, the electromagnet 23 is attracted to the magnetic attraction surface 143 after being energized, and the telescopic tube 142 can abut against the stopper 222 after being extended.

[0035] It should be noted that the erection units 1 in this embodiment are multi-layered and evenly spaced on the inner side of the box body 3, wherein each layer of the erection units 1 includes a plurality of groups of horizontally arrayed mesh panels 11 on the same horizontal support surface. A group of connectors 12 are threadedly connected on both sides of each group of mesh panels 11, so that the mesh panels 11 can be erected on both sides of the box body 3. Multiple groups of symmetrically arranged slide rails 31 are welded on the side walls of the box body 3, and a group of slide plates 13 are slidably connected to the inner side of each slide rail 31, and multiple groups of connectors 12 can be connected to the inner side of the slide plate 13. Each slide plate 13 can overlap multiple groups of connectors 12 and mesh panels 11, so that the mesh panels 11 can slide horizontally.

[0036] Preferably, a set of driving units 2 are connected to the gaps on the side walls of the box body 3. The driving unit 2 can drive the slide plate 13 to slide. Two sets of electric push rods 24 are externally arranged at the bottom of the side of the box body 3, and a set of extension plates 21 are fixedly sleeved at the push rods of the electric push rods 24. The length of the extension plate 21 is consistent with that of the box body 3, so that the bottom of the extension plate 21 is clamped at the bottom of the box body 3, and the top of the extension plate 21 is slidably clamped at the end of the box body 3, so that after the electric push rod 24 is pushed out, the extension plate 21 is pushed vertically, thereby driving the slide plates 13 on both sides of the extension plate 21 to slide.

[0037] Preferably, the first push rod 14 and the second push rod 15 have the same structure. The first push rod 14 is composed of a sleeve 141, a telescopic cylinder 142 arranged on the inner side of the sleeve 141, and a magnetic surface 143 arranged on the end face of the telescopic cylinder 142. That is, the second push rod 15 is also composed of a sleeve 141, a telescopic cylinder 142, and a magnetic surface 143. And a group of conical springs 16 are fixedly connected to the inner side of the sleeve 141 and the telescopic cylinder 142. The sleeve 141 is embedded and fixedly connected to the end face of the slide plate 13, and a group of conical springs 16 are fixedly connected to the bottom of the sleeve 141, and one end of the conical spring 16 is fixedly connected to the inner end face of the telescopic cylinder 142.

[0038] Preferably, a plurality of groups of protrusions 22 having the same spacing as the slide rail 31 are provided on one side of the extension plate 21, and a placement groove 221 is provided on the inner side of the protrusion 22, and a group of electromagnets 23 are placed in the placement groove 221. One side of each group of electromagnets 23 is connected to a connection circuit 211, and the connection circuit 211 can control whether each group of electromagnets 23 is energized. A thicker stopper 222 is provided on the inner side of the protrusion 22, and the stopper 222 can facilitate the translation of the extended telescopic cylinder 142.

[0039] Preferably, one side of the connection circuit 211 is connected to a group of sub-controllers 212, and the sub-controllers 212 are prior art, and can be PLC / programmable logic controllers, which can be easily controlled by programming to perform specific logic control tasks and configure appropriate input and output modules. The PLC can easily control the on and off states of multiple electromagnets and realize complex control logic, so that it can control whether the parallel circuits of multiple groups of electromagnets 23 connected in parallel to the connection circuit 211 are energized, thereby realizing the power supply requirements for the electromagnets 23.

[0040] In normal state, the conical spring 16 will retract the telescopic cylinder 142 into the sleeve 141 under the action of tension, and since the sleeve 141 is embedded in the end face of the slide 13, the telescopic cylinder 142 will be exposed less. In addition, the magnetic surface 143 is fixedly connected to the outer end face of the telescopic cylinder 142. When the electric push rod 24 at the bottom of the box body 3 pushes the extension plate 21 to move horizontally, the electromagnet 23 is not energized at this time, and the telescopic cylinder 142 retracts inside the sleeve 141, causing the block 222 on one side of the extension plate 21 to be unable to contact the telescopic cylinder 142, and thus the telescopic cylinder 142 cannot indirectly push the slide 13 to move horizontally.

[0041] When the electromagnet 23 at a certain place is energized, it will be magnetic. When the electric push rod 24 at the bottom of the box 3 pushes the extension plate 21 to move horizontally, the magnetic surface 143 at the end face of the second push rod 15 embedded in the inner side of the slide 13 will be magnetically attracted by the electromagnet 23, thereby lengthening the second push rod 15 and stretching the conical spring 16 inside it. Finally, under the magnetic attraction of the electromagnet 23 and the contact with the stopper 222, the second push rod 15 can push the slide 13 to move horizontally, automatically pushing out the mesh plate 11 at that place, thereby realizing that a group of electric push rods 24 pushes out multiple mesh plates 11 in the box 3, avoiding manual pulling out by staff and reducing the risk of scalding. The structure is simple, and the installation and maintenance costs are low.

[0042] In summary, the device can push out a certain layer of erection unit 1 or multiple layers of erection unit 1 according to usage requirements; in addition, the mesh plate can be flipped 11 degrees, and the fruits and vegetables can fall down and be collected uniformly. Specifically, through the automatic control of the electric push rod 24 and the electromagnet 23, the operational safety and convenience of the air source heat pump fruit and vegetable dryer are significantly improved. By controlling the electromagnet 23 to be energized, the second push rod 15 is extended and abuts against the block 222, thereby smoothly pushing out the erection unit 1, reducing the labor intensity and risk of scalding caused by manual pushing and pulling by the staff. In addition, the structure adopted by the device is simple, which is convenient for installation and disassembly by the staff. Example

[0043] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and which is different from the first embodiment in that it includes a plurality of sets of erection units 1 and two sets of driving units 2, and each set of erection units 1 is driven by the driving units 2 on both sides thereof; Each set of erection units 1 includes a plurality of horizontally arrayed mesh panels 11, two sets of connecting members 12 disposed on both sides of each set of mesh panels 11, a slide plate 13 disposed on one side of the mesh panels 11, a first stopper 14 disposed on the connecting member 12, and a second stopper 15 disposed on the slide plate 13; The driving unit 2 includes an extension plate 21 disposed on the outside of the slide plate 13, a plurality of groups of protrusions 22 disposed on one side of the extension plate 21, an electromagnet 23 disposed on the inner side of each group of protrusions 22, and an electric push rod 24 disposed at the bottom of the extension plate 21; The first stopper 14 and the second stopper 15 both cooperate with the electromagnet 23 .

[0044] Furthermore, it also includes a box body 3, which includes a plurality of slide rails 31 arranged on its side wall and a placement box 32 arranged outside the box body 3; The slide rail 31 includes a spring piece 311 disposed at an end thereof and an escape groove 312 disposed at an outer side of the slide rail 31 .

[0045] Furthermore, the slide plate 13 includes a plurality of L-shaped grooves 131 arranged in a horizontal array through the end surface thereof; The connecting member 12 includes a Z-shaped rod 121 fixedly disposed on one side of each set of mesh panels 11 , and a push plate 122 disposed on one side of the Z-shaped rod 121 .

[0046] Furthermore, the push plate 122 includes a connecting portion 1221 hinged to the Z-shaped rod 121 , and a moving portion 1222 at the bottom of the connecting portion 1221 .

[0047] Further, the connection portion 1221 includes a linear array of hinge holes 12211; The moving part 1222 includes a limiting hole 12221 penetratingly arranged on its end surface; The slide plate 13 further includes a fixing hole 132 penetratingly disposed on its end surface; The space where the limiting hole 12221 and the fixing hole 132 are located is relatively misaligned.

[0048] Furthermore, the first stopper 14 is fixedly disposed in the limiting hole 12221; The second stopper 15 is fixedly disposed in the fixing hole 132; The first stopper 14 and the second stopper 15 have the same structure.

[0049] Furthermore, the first stopper 14 includes a sleeve 141 disposed inside the limiting hole 12221, a telescopic cylinder 142 disposed inside the sleeve 141, and a magnetic surface 143 disposed on the end surface of the telescopic cylinder 142; A group of conical springs 16 are fixedly connected to the inner sides of the sleeve 141 and the telescopic cylinder 142 .

[0050] Furthermore, the extension board 21 includes a connection circuit 211 disposed on the inner side thereof, and a sub-controller 212 disposed on one side of the connection circuit 211; The sub-controller 212 can control the power supply of each electromagnet 23 separately.

[0051] Furthermore, the protrusion 22 includes a placement groove 221 disposed on an inner side thereof, and a stopper 222 disposed on one side of the placement groove 221 .

[0052] Furthermore, the electromagnet 23 is attracted to the magnetic attraction surface 143 after being energized, and the telescopic tube 142 can abut against the stopper 222 after being extended.

[0053] It should be noted that the multiple groups of mesh plates 11 in this example are horizontally arranged on the inner side of the slides 13 on both sides, together forming a laying plane, which is convenient for placing and drying fruits and vegetables, but each group of mesh plates 11 can be driven by the electric push rod 24 to flip over, and then pour out the dried fruits and vegetables, which is convenient for the staff to collect them uniformly.

[0054] Preferably, a linear array of L-shaped grooves 131 is provided on the plate body 13 through both end surfaces, and the short sides of the L-shaped grooves 131 face downwards, such as Figure 3 As shown. The connector 12 is connected to the L-shaped groove 131, so that it can be turned 90 degrees under the push of the electric push rod 24, and the dried fruits and vegetables are tilted into the storage frame placed in advance at the bottom of the box body 3, so as to achieve rapid collection and reduce the work intensity of the staff. The connector 12 is composed of a Z-shaped rod 121 and a push plate 122 arranged on one side of the Z-shaped rod 121. Among them, one end of the Z-shaped rod 121 connected to the mesh plate 11 is opened in the shape of a threaded column, and a threaded groove is opened in the center of the frame of the mesh plate 11, which is convenient for threading the Z-shaped rod 121 to be fixed on the mesh plate 11.

[0055] Preferably, the slide rail 31 and the slots of the skateboard 13 cooperate with each other so that the skateboard 13 can slide and translate in the slide rail 31, and the Z-shaped rod 121 is inserted into the L-shaped slot 131 of the skateboard 13 on the outside of the skateboard 13 and is threadedly connected to the mesh plate 11, thereby achieving the function of the skateboard 13 fixing and clamping the mesh plate 11, and the modular installation and disassembly are simple.

[0056] Preferably, the push plate 122 is hinged on the outside of the Z-shaped rod 121, and the push plate 122 is divided into a connecting portion 1221 hinged to the other end of the Z-shaped rod 121, and a moving portion 1222 at the bottom of the connecting portion 1221. The moving portion 1222 is slidably mounted on a straight plate protruding from the inner side of the slide rail 31, and is horizontally mounted on the outside of the slide plate 13 of each layer. In addition, the top of the connecting portion 1221 has a plurality of groups of hinge holes 12211 in a horizontal linear array, and the hinge holes 12211 can be hinged together with the outer rod body of the Z-shaped rod 121, so that when the moving portion 1222 arranged symmetrically on both sides is translated, the Z-shaped rod 121 can be hinged to the hinge holes 12211 of the connecting portion 1221, so that the Z-shaped rod 121 can be flipped 90 degrees under the hinge action of the hinge holes 12211 of the connecting portion 1221.

[0057] Preferably, the end surface of the moving part 1222 is provided with a limiting hole 12221, and the end surface of the slide plate 13 is provided with a fixing hole 132. The first push rod 14 is fixedly disposed in the limiting hole 12221; the second push rod 15 is fixedly disposed in the fixing hole 132. The first push rod 14 and the second push rod 15 have the same structure, as described in the first embodiment, the first push rod 14 and the second push rod 15 will both extend under the attraction of the electromagnet 23, and thus be pushed to translate by the stopper 222.

[0058] Preferably, the space where the limiting hole 12221 and the fixing hole 132 are located is relatively misaligned. Specifically, when the slide plate 13 is pushed into the inner side of the box body 3, the position of the fixing hole 132 penetrating the end surface of the slide plate 13 is located deep inside the box body 3, and the position of the upper limit hole 12221 on the end surface of the moving part 1222 can be located near the cabinet door end of the box body 3, so that when the electric push rod 24 at the bottom pushes the slide plate 13 or the moving part 1222, they do not interfere with each other.

[0059] Preferably, a spring sheet 311 is welded on the side of the slide rail 31 close to the cabinet door, and the spring sheet 311 is symmetrical up and down, and an avoidance groove 312 is set on the outside of the slide rail 31. The spring sheet 311 has a certain elasticity, so that after the slide plate 13 is pushed into the inside of the slide rail 31, the slide plate 13 will not easily slide out under the limit of the spring sheet 311, so that when the moving part 1222 is pushed to move horizontally, the slide plate 13 remains relatively still; the Z-shaped rod 121 smoothly turns 90 degrees. The avoidance groove 312 on the outside of the slide rail 31 allows the push plate 122 on the outside of the slide plate 13 to slide out smoothly, so that the slide plate 13 can be pushed out smoothly.

[0060] The other structures are the same as those in the first embodiment.

[0061] During use, when it is necessary to push out a certain layer of the erection unit 1, the electric push rod 24 extends from the inside of the device and first passes through the position where the second push rod 15 is set. At this time, the sub-controller 212 on one side of the connection circuit 211 controls the electromagnet 23 at that location to be energized, and the electromagnet 23 sucks out the telescopic cylinder 142 inside the second push rod 15 and stretches the conical spring 16 inside the telescopic cylinder 142, increasing the length of the second push rod 15 so that it can contact the stopper 222 on one side of the protrusion 22. The electric push rod 24 continues to extend, and finally pushes out the erection unit 1 of the layer or multiple layers, making it convenient for the staff to turn over and inspect the fruits and vegetables in the erection unit 1, reducing the labor intensity of manual pushing and pulling.

[0062] When it is necessary to collect the dried fruits and vegetables, the electric push rod 24 also extends from the inside of the device and passes through the position where the second push rod 15 is set, but at this time the sub-controller controls the electromagnet 23 at this position to be powered off, so that the second push rod 15 cannot be pushed by the block 222. The electric push rod 24 continues to extend and translates to the position of the first push rod 14 on the end face of the moving part 1222. The electromagnet 23 is powered on to suck out the first push rod 14 at this position. The first push rod 14 is pushed by the block 222, driving the Z-shaped rod 121 to translate in the L-shaped groove 131 and then flip 90 degrees, so that the fruits and vegetables laid on each mesh plate 11 are tilted and poured into the storage frame placed in advance at the bottom of the bottom box 3, realizing rapid collection without collecting fruits and vegetables layer by layer, which greatly reduces the workload of the staff.

[0063] In summary, the device can push out a certain layer of erection unit 1 or multiple layers of erection unit 1 according to the use requirements; in addition, the mesh plate 11 can be flipped over, and the fruits and vegetables can be collected uniformly after falling down. Specifically, through the automatic control of the electric push rod 24 and the electromagnet 23, the operational safety and convenience of the air source heat pump fruit and vegetable dryer are significantly improved. By controlling the electromagnet 23 to be energized, the second push rod 15 is extended and abuts against the block 222, so that the erection unit 1 is smoothly pushed out, reducing the labor intensity and scalding risk of manual pushing and pulling by the staff. When collecting the dried fruits and vegetables, the electric push rod 24 controls the electromagnet 23 to be energized, so that the second push rod 15 cannot be pushed by the block 222, and continues to extend and drive the first push rod 14 and the Z-shaped rod 121 to flip, and quickly pour the fruits and vegetables into the storage frame, realizing efficient operation without manual collection layer by layer. In addition, the structure adopted by the device is simple, which is convenient for installation and disassembly by the staff.
