[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1: Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, a solar fruit drying machine includes a baking box 100, a solar device 200, a baking device 300 for providing baking heat and a drying fan 400 for auxiliary drying. The baking box 100 is provided with a baking cavity 11 for accommodating products. The solar device 200 includes a solar panel 21 for absorbing solar energy and converting electrical energy. The solar panel 21 is electrically connected to the drying fan 400 to provide electrical energy to drive the drying fan 400 to rotate. The drying fan 400 exhausts air toward the baking cavity 11. The baking cavity 11 is provided with a vent 123 connected to the outside.

[0031] Optionally, the baking oven 100 is inlaid with a transparent material that is translucent. The transparent material can be glass, plastic, plastic film or other materials with good light transmittance. Preferably, the transparent material of the baking oven 100 is plastic with good light transmittance and high temperature resistance. Plastic has low cost, good plasticity and is easy to shape. It also has certain structural strength and shock resistance, and has good comprehensive performance, and is suitable for outdoor mobile scenes.

[0032] Specifically, in the present embodiment, the baking box 100 is a container body of the solar fruit drying machine for placing the baked products, and the baked products can be dried fruits, dried meat, dried fish or other foods or items that can be baked and air-dried. The baking box 100 is made of a metal sheet metal shell inlaid with transparent materials and can be opened and closed for easy placement and removal of products. The baking cavity 11 is connected to the outside world through multiple ventilation holes 123 so that air circulation can take away moisture from the products. The solar device 200 is an electric device used by the solar fruit drying machine to absorb natural light heat and convert it into electrical energy. The solar panel 21 is a conversion panel for converting solar energy into electrical energy. The baking device 300 is a heating device used by the solar fruit drying machine to heat the inside of the baking box 100. The baking device 300 is electrically connected to an external power supply so that the drying fan 400 can output hot air when it rotates. The drying fan 400 is a wind device used by the solar fruit drying machine to inhale air flow from the outside and blow it to the product for air drying. The drying fan 400 can use a 12V low-pressure fan to facilitate adaptation to the power supply of the solar device 200. The solar device 200 is electrically connected to the drying fan 400.

[0033] More specifically, when in use, the user moves the solar fruit dryer to a location outdoors that can be exposed to the sun, opens the baking box 100, puts the product to be dried in the baking cavity 11, closes the baking box 100 and starts the solar fruit dryer. The solar panel 21 irradiated by the natural light and heat of the sun supplies the converted electric energy to the drying fan 400, and the drying fan 400 starts and draws in air flow from the outside. The air flow is heated when passing through the baking device 300, causing the air flow to heat up and form hot air. The hot air is output from the drying fan 400 and circulates in the baking cavity 11. The heat of baking evaporates the moisture of the product, and the air flow output by the drying fan 400 brings the moisture out of the outside through the vent 123. The circulating air achieves the effect of baking and drying. In addition, the baking box 100 is located outdoors and can also be irradiated by the natural light and heat of the sun. The natural light and heat pass through the transparent material into the baking cavity 11 and irradiate on the product, so that the product can achieve the effect of natural drying.

[0034] The present embodiment adopts a method of simultaneously performing baking and air-drying and natural drying to speed up the drying efficiency. Due to the heat support of natural light heat, the baking device 300 does not need to output too much heat to meet the temperature required for baking and air-drying. Compared with the method of baking by relying solely on the heat output of the baking device 300, the use of natural light heat and electricity provided by solar energy conversion can save a lot of energy consumption. In addition to energy saving and environmental protection, it can also ensure the baking quality of the product and facilitate user use.

[0035] Embodiment 2: Specifically, based on Embodiment 1, in this embodiment, the vent 123 located on the air inlet side may be provided with a dust screen, and a screen net with a smaller mesh size may be installed at the vent 123. When dust or mosquitoes are inhaled, they are blocked by the screen net and remain on the screen net, reducing the chance of directly entering the vent 123. When cleaning the baking oven 100, the screen net can be cleaned at the same time to keep the screen net with a good air flow rate.

[0036] Example 3: Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, the baking oven 100 is divided into an upper box body 12 and a lower box body 13. The upper box body 12 covers the lower box body 13 to form the baking cavity 11. The connection between the upper box body 12 and the lower box body 13 is connected by a locking piece.

[0037] Specifically, based on the above embodiments, in the present embodiment, the upper box body 12 is a covering component of the baking oven 100 for inlaying and installing transparent materials and installing the baking device 300, and the lower box body 13 is a bracket component of the baking oven 100 for supporting the overall structure to be stably placed. The upper box body 12 and the lower box body 13 are connected in cooperation to form a baking cavity 11 for placing products. In order to further improve the stability of the connection between the upper box body 12 and the lower box body 13, the baking oven 100 is provided with a locking member for strengthening stability at a position close to the outside. The locking member includes a limit lock 17 for snap-fit ​​connection. The limit lock 17 is located at the edge of the lower box body 13 close to the upper box body 12. A plurality of limit locks 17 are arranged at intervals along the contact connection between the upper box body 12 and the lower box body 13, and the vents 123 are respectively arranged on both sides of the length direction of the upper box body 12.

[0038] More specifically, the limit lock 17 includes a locking hole 121 located in the upper box body 12 and a buckle 171 hinged on the limit lock 17. The buckle 171 is a buckle accessory formed by bending a bent metal wire and has a certain elasticity and structural strength. The buckle 171 is buckled in the locking hole 121 to achieve a locked state between the upper box body 12 and the lower box body 13. When in use, the user opens the limit lock 17 to disengage the buckle 171 from the locking hole 121. After the upper box body 12 loses the position restriction of the buckle 171, the user can manually lift the upper box body 12. After the upper box body 12 is separated from the lower box body 13, the products to be baked can be placed in it. When closing, the user covers the upper box body 12 on the lower box body 13 and manually buckles each buckle 171 toward the locking hole 121 to achieve a locking effect.

[0039] Example 4: Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, the baking oven 100 is installed with at least one transparent structural surface 122 for facilitating light transmission. The transparent structural surface 122 is arranged along the length direction of the baking oven 100 , and the transparent structural surface 122 is installed on the upper box body 12 .

[0040] Optionally, the transparent material of the transparent structural surface 122 can be glass, plastic, plastic film or other materials with good light transmittance. Preferably, the transparent material of the transparent structural surface 122 is plastic with good light transmittance and high temperature resistance. Plastic has low cost, good plasticity and is easy to shape. It also has certain structural strength and shock resistance, and has good overall performance, and is suitable for outdoor mobile scenes.

[0041] Specifically, based on the above embodiments, in this embodiment, the transparent structural surface 122 is a structural component of the baking oven 100 for inlaying transparent materials. The transparent structural surface 122 is composed of a metal frame enclosed on the outside of the transparent material. Multiple transparent structural surfaces 122 are spliced ​​to form an upper box body 12 that can transmit light at multiple angles, so as to facilitate natural light and heat to enter the baking cavity 11. More specifically, the longer side of the horizontal cross-section of the baking oven is the side length E, and the shorter side of the horizontal cross-section of the baking oven is the side length F. The length direction of the transparent structural surface 122 is in the same direction as the length direction of the side length F. Multiple transparent structural surfaces 122 are arranged at intervals around the central circumference of the baking cavity 11 to maximize the light transmission area of ​​the baking oven 100.

[0042] Example 5: Figure 1 , Figure 2 and Figure 7 As shown, the transparent structural surface 122 adopts a flat surface structure, and the transparent structural surface 122 includes a structural surface A, a structural surface B and a structural surface C that are built on the upper box body 12 to form a trapezoidal structure.

[0043] Specifically, based on the above embodiments, in this embodiment, the transparent structural surface 122 adopts a flat straight surface structure as the shaping surface of the transparent material. The transparent structural surface 122 can be divided into three parts, namely, a structural surface A, a structural surface B and a structural surface C, with similar lengths and widths according to different positions and different angles. The structural surface A, the structural surface B and the structural surface C are fixedly connected in sequence to form a ladder structure, wherein the structural surface A and the structural surface C serve as the waist part of the ladder, and the side of the structural surface A away from the structural surface B is fixedly connected to one side of the upper box body 12, and the side of the structural surface C away from the structural surface B is fixedly connected to the other side of the upper box body 12. With such a design, the internal space of the upper box body 12 is increased, and more products to be dried can be accommodated. The vents 123 are respectively located on the two side surfaces enclosed by the structural surfaces A, the structural surfaces B and the structural surfaces C in the length direction. The wind flows from the outside into the baking cavity 11 through the vents 123 on one side and flows out from the vents 123 on the other side, thereby realizing air circulation in the baking cavity 11.

[0044] Example 6: Figure 1 , Figure 2 as well as Figures 6 to 8 As shown, the side D of the lower box body 13 is equipped with an openable flip door 131 through a hinge assembly 132, and the flip door 131 is equipped with a door handle 133 for easy gripping, and the door handle 133 is horizontally arranged on the side of the flip door 131 facing the outside.

[0045] Specifically, based on the above embodiment, in this embodiment, the side D of the lower box body 13 is the side of the lower box body 13 facing the front, and the flip door 131 is an entrance and exit passage of the baking oven 100 for the user to open and put the product. When the flip door 131 is not provided, the user can separate the upper box body 12 and the lower box body 13 by opening the limit lock 17 to put the product in. After the flip door 131 is adopted, the product can be directly put in by opening the flip door 131, and the product can be put in without repeatedly opening and buckling multiple limit locks 17. The flip door 131 is connected by the hinge assembly 132 It is installed on the side of the lower box body 13 away from the upper box body 12. When opening, you only need to flip it downward. A door handle 133 that is easy to hold is installed on the side of the flip door 131 close to the upper box body 12. The door handle 133 is a handhold for the user to pull. Since the temperature of the baking cavity 11 is relatively high, the user may get burned if he or she directly touches it with his or her hands. Therefore, the door handle 133 extending out of the flip door 131 is arranged to avoid burns caused by heat transfer. Preferably, an insulating sheath with poor thermal conductivity is provided on the outside of the door handle 133 to further reduce heat transfer and facilitate user use.

[0046] Example 7: Figure 2 as well as Figures 6 to 8 As shown, a flip magnet 134 is installed at the closed contact point between the flip door 131 and the lower box body 13 , and the flip magnet 134 is located on a side of the lower box body 13 close to the flip door 131 and at an end away from the hinge assembly 132 .

[0047] Specifically, based on the above embodiments, in this embodiment, the flip door 131 is made of a metal material that can be magnetically attracted, and the flip magnetic attractors 134 are respectively installed on both sides of the lower box body 13 in the length direction. When the flip magnetic attractors 134 are not installed, there is no corresponding measure to restrict the opening of the flip door 131 after the user closes it. When the baking oven 100 is blown by wind or slightly collided, the flip door 131 is easily separated from the lower box body 13 and falls down around the hinge assembly under the influence of its own weight and flips up. After the flip door 131 is opened, the dissipation of hot air will slow down the baking progress and cause dust and mosquitoes to enter the baking cavity 11, affecting the baking quality. After the flip magnetic attractors 134 are added, when the user closes the flip door 131, the flip door 131 can be magnetically attracted to the flip magnetic attractors 134, thereby enhancing the locking stability of the flip door 131 and preventing the flip door 131 from falling off and opening at will, thereby ensuring the smooth baking process of the product and the baking quality of the product.

[0048] Example 8: Figure 1 , Figure 2 as well as Figures 5 to 7As shown, a box frame 14 for stable support is provided at the bottom of the lower box 13, and the box frame 14 includes a plurality of vertically arranged frame legs 141, and a pulley block 15 for easy movement is installed at the bottom of the frame legs 141, and the pulley block 15 includes a pulley 151 for rolling and a brake mechanism 152 for limiting the rotation of the pulley 151.

[0049] Optionally, the pulley 151 can be made of metal, plastic, rubber or other materials. Preferably, the pulley 151 is made of rubber. Rubber has a certain degree of softness and elasticity, and can alleviate the vibration caused by the uneven outdoor ground during movement. The vibration will be transmitted to the baking oven 100 through the box frame 14, which may affect the placement of the product at the least, or cause the product to vibrate and fall. The pulley 151 made of rubber can reduce the transmission of vibration, reduce the vibration and fall of the product to a certain extent, and facilitate user use.

[0050] Specifically, based on the above embodiments, in this embodiment, the box frame 14 is a frame composed of a plurality of rectangular profiles, the vertically arranged profiles are frame legs 141, and the plurality of frame legs 141 are respectively arranged at the corners of the corresponding positions at the bottom of the lower box 13, so that the baking oven 100 can be stably placed from multi-point ground support, and a frame crossbeam for reinforcement is also installed between adjacent frame legs 141, and the frame crossbeam is transversely arranged in the space between the middle position of the frame legs 141 and the ground, so as to further improve the structural stability of the box frame 14, and a pulley block 15 for easy movement is installed on the side of the frame legs 141 close to the ground, and the pulley block 15 is composed of a pulley 151, a steering mechanism and a brake mechanism 152, and the steering mechanism is hinged to the frame legs 141 and can be moved around the frame legs 1 The central axis of the oven 100 rotates circumferentially, the pulley 151 is installed on the steering mechanism for contacting the ground, and the brake mechanism 152 is hinged on the steering mechanism and can be used to press the pulley 151. When in use, multiple pulley groups 15 are respectively installed at the bottom of the frame legs 141 at corresponding positions, and multiple pulleys 151 contact the ground at the same time to support the weight of the box frame 14. When it is necessary to move, the user pushes the oven 100 to drive the pulley 151 to roll on the ground to realize the movement of the oven 100. When it is necessary to stop, the user steps on the brake pedal of the brake mechanism 152 to press the pulley 151 to stop the pulley 151 from rotating, so as to stop the oven 100 in a stable position. The brake mechanism 152 can prevent the oven 100 from shaking and displacement due to wind and slight collision, thereby enhancing the standing stability of the oven 100.

[0051] Example 9: Figure 2 as well as Figures 6 to 8As shown, the baking oven 100 includes a placement rack for placing products, and the placement rack includes a supporting bracket 161 and a supporting grid 162. The supporting bracket 161 is provided with a plurality of shelf structures of different heights, and a plurality of the supporting grids 162 can be placed on the shelf structures at different heights respectively.

[0052] Specifically, based on the above embodiments, in the present embodiment, the placement rack is a drying rack located inside the oven 100 for stably placing products. The supporting bracket 161 is a layered structure of layers of the placement rack at different heights, having a vertically arranged first bracket and a horizontally arranged second bracket. A plurality of second brackets are enclosed on the outside of the supporting grid 162 to reinforce the supporting grid 162. A plurality of first brackets are respectively fixed at the corners of the supporting grid 162 and arranged toward the lower side. A plurality of first brackets and a plurality of second brackets form a shelf structure. Depending on the size of the product, a shelf structure with different layered heights can be selected to adapt to the placement space of the product. The supporting grid 162 is The placement rack is a net structure for supporting the product. The supporting net frame 162 is formed by a plurality of metal wires crisscrossed and woven at intervals to form a planar net structure. The metal wire spacing distance of the supporting net frame 162 is smaller than the minimum cross-sectional outer diameter of the product to prevent the product from falling downward through the supporting net frame 162 during the drying process. More specifically, the supporting net frame 162 is formed by weaving metal wires to form through holes in one of a variety of shapes such as square, rectangular, diamond, or triangular. Preferably, a square structure is easier to produce. When in use, the user can take out the placement rack in advance, and after placing the product on the placement rack, put the placement rack into the baking cavity 11 to start the baking process.

[0053] Embodiment 10: Specifically, based on Embodiment 9, in this embodiment, two or more racks can be used inside the baking oven 100 to facilitate users to dry products of different types or categories separately. When taking out, they can also be taken out and replaced separately without conflicting with other racks. Racks with different layer heights can also be used to place products to accommodate products of different sizes, thereby improving the product adaptability and practicality of the solar fruit drying machine.

[0054] Example 11: Figure 4 and Figure 6 As shown, the baking device 300 is provided with a temperature control knob 31 for facilitating temperature regulation. The temperature control knob 31 is installed on the outside of the baking oven 100. The baking oven 100 is provided with a temperature control scale for facilitating temperature regulation at a position corresponding to the temperature control knob 31. The temperature control scale is arranged at intervals around the central circumference of the temperature control knob 31.

[0055] Specifically, based on the above embodiments, in this embodiment, the baking device 300 includes a heater for providing heat and a controller for adjusting the temperature. After the heater generates heat through resistance heating, the temperature of the heat is controlled by the controller. The controller includes a temperature adjustment knob 31 arranged on the outside of the baking box 100. The user can adjust the heat temperature of the heater by turning the temperature adjustment knob 31 to make a temperature adjustment suitable for baking according to the actual changes in the external environment. When the natural light and heat are sufficient during the day, the user can lower the heating temperature of the heater through the temperature adjustment knob 31 to save electricity and energy. On cloudy days when the natural light and heat are sparse, the user can adjust the temperature of the heater by turning the temperature adjustment knob 31 to save electricity and energy. When the sun is weak, the user can increase the heating temperature of the heater through the temperature control knob 31 to meet the heat required for baking in the baking oven 100 when the sun is insufficient. More specifically, at the position corresponding to the temperature control knob 31 on the outside of the baking oven 100, there is a temperature control scale arranged at intervals around the central circumference of the temperature control knob 31. The temperature control scale displays the temperature that can be set by the temperature control knob 31 at the corresponding turning angle. When the user turns the temperature control knob 31, the actual adjusted temperature can be controlled with reference to the indication of the temperature control scale. The temperature control scale can use one or a combination of multiple display texts or patterns such as scale lines, numbers, English, Chinese, etc., for user convenience.

[0057] Specifically, based on the above embodiments, in this embodiment, the solar mounting frame 22 is a mounting bracket for the solar device 200 to be installed on the outside of the baking oven 100, and the bogie 23 is a mechanism hinged between the solar mounting frame 22 and the solar panel 21 for steering. The bogie 23 includes a horizontal hinge part for horizontal steering and a flip hinge part for horizontal flipping. The bogie 23 is connected to the solar mounting frame 22 through the horizontal hinge part, and the bogie 23 is connected to the solar panel 21 through the flip hinge part, so that the absorption angle can be adjusted horizontally and horizontally. When in use, the user rotates the bogie 23 according to the direction of sunlight to drive the solar panel 21 to the direction of sunlight. The sunlight irradiates the solar panel 21 to realize photoelectric conversion and is transmitted to the drying fan 400 to power it, so that the user can adjust the direction of the solar panel 21 and improve the absorption efficiency.

[0058] Example 13: Figures 1 to 8As shown, based on the above embodiments, the preferred working principle and specific implementation method of the utility model are as follows: before use, the user moves the baking oven 100 to a sunny location outdoors through the pulley set 15, and then steps on the brake mechanism 152 so that the brake mechanism 152 presses the pulley 151 to limit the placement position of the baking oven. The user covers the upper box body 12 on the lower box body 13 to form a baking cavity, and then uses the limit lock 17 to buckle and lock the upper box body 12 and the lower box body 13 to complete the installation process.

[0059] During use, the user holds the door handle 133 to pull and open the flip door 131, and the flip door 131 is lowered downward around the hinge assembly 132. The user takes out all the placement racks from the baking cavity 11, and places the products to be baked on each supporting grid 162 in turn. After the products are laid, the user can put all the placement racks back into the baking cavity 11, lift and close the flip door 131 through the door handle 133, and then the flip door 131 is magnetically adsorbed by the flip magnet 134 to complete the preparation process.

[0060] When starting, the user turns on the solar device 200 to absorb solar energy and converts it into electrical energy through the solar panel 21 using the photoelectric conversion effect. The electrical energy is supplied to the drying fan 400 and then drives the drying fan 400 to rotate and discharge air. At the same time, the baking device 300 is turned on to make the baking device 300 powered on and heated. The air outlet direction of the drying fan 400 is toward the baking inner cavity 11. The drying fan 400 drives the external air flow to enter from the vent 123 on the air inlet side. After being heated by the baking device 300, hot air is formed and blown toward the baking inner cavity 11 through the drying fan 400. The hot air is blown into the baking inner cavity 11 by the drying fan 400. 11 circulates around and bakes the product. After the product is heated, the internal moisture evaporates into the air outside, and the hot air leaves from the vent 123 on the air outlet side with the moist air. While the hot air continues to bake the product, the natural light and heat emitted by the sun shines into the baking cavity 11 through the transparent structural surface 122. The natural light and heat are used to illuminate and bake the product. The baking and air-drying and natural air-drying are carried out simultaneously, so that the baking process can achieve the drying and air-drying effect. After the baking process is completed, the user can close the baking device 300 and open the flip door 131 to take out the dried product.

[0061] This baking method can speed up the drying efficiency of the product. Due to the heat from natural light and heat, the baking device 300 does not need to output too much heat to meet the temperature required for baking and air-drying. Compared with the baking method that relies solely on the heat output of the baking device 300, the use of natural light and heat and the electricity provided by solar energy conversion can save a lot of energy consumption. In addition to energy saving and environmental protection, it can also ensure the baking quality of the product and facilitate user use.

[0062] In addition, the user can also rotate the bogie 23 according to the direction of sunlight to drive the solar panel 21 toward the direction of sunlight, and adjust the direction of the solar panel 21 by rotating the bogie 23 to better absorb solar heat.

[0063] In addition, the user can also make temperature adjustments suitable for baking according to actual changes in the external environment. When natural light and heat are sufficient during the day, the user can lower the heating temperature of the heater through the temperature adjustment knob 31 to save electricity and energy. When natural light and heat are relatively weak on cloudy days, the user can increase the heating temperature of the heater through the temperature adjustment knob 31 to meet the heat required for baking in the baking box 100 when sunlight is insufficient.

[0064] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
