Description
Technical Field
[0001] This utility model relates to the technical field of fruit and vegetable dryers, specifically an air-source heat pump fruit and vegetable dryer. Background Technology
[0002] With increasing health awareness, eating fruits and vegetables has become a daily habit. The emergence of fruit and vegetable dehydrators has provided people with more ways to preserve fresh fruits and vegetables. Fruit and vegetable dehydrators evaporate the moisture from fruits and vegetables, thus extending their shelf life. At the same time, they also preserve the nutrients in the food, preventing them from decomposing or being lost during storage. Therefore, one of the biggest advantages of using fruit and vegetable dehydrators is that they ensure that various nutrients in fruits and vegetables, such as vitamins and minerals, are not excessively consumed. Air source heat pump dehydrators are commonly used for fruit and vegetable dehydration.
[0003] Existing air source heat pump fruit and vegetable dryers have low drying efficiency and tend to lose a lot of heat during heat transfer, resulting in high energy consumption and making them unsuitable for rapid drying of fruits and vegetables. Utility Model Content

A second insulation board is fixedly connected to the inner surface of the heat conduction interface. A third insulation board is fixedly connected to the inner surface of the drying chamber. A fourth insulation board is fixedly connected to the inner surface of the opening and closing door. A supporting guide rail is fixedly connected to the inner wall of the third insulation board. A fruit and vegetable tray is provided inside the drying chamber. Fixed guide wheels are fixedly connected to the sides of the lower surface of the fruit and vegetable tray. A top cover is movably provided on the top of the drying chamber. Opening and closing buckles are provided at the corners of the outer surfaces of the drying chamber and the top cover. A dehumidification channel is provided inside the top cover.
[0006] Preferably, the end of the heat conduction channel away from the air source heat pump host is connected to the end of the heat conduction interface away from the drying box, and the inner cavity of the drying box is connected to the interior of the air source heat pump host through the heat conduction channel and the heat conduction interface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] like Figure 1-4 As shown, this utility model provides an air source heat pump fruit and vegetable dryer, including an air source heat pump main unit 1 and a drying chamber 2. The outer surface of the air source heat pump main unit 1 is fixedly connected to a controller 3 and a heat conduction channel 4. The outer surface of the drying chamber 2 is fixedly connected to a heat conduction interface 5. The outer surface of the drying chamber 2 is hinged to an opening and closing door 7. The inner surface of the heat conduction channel 4 is fixedly connected to a first insulation board 8. The inner surface of the heat conduction interface 5 is fixedly connected to a second insulation board 9. The inner surface of the drying chamber 2 is fixedly connected to a third insulation board 10. The inner surface of the opening and closing door 7 is fixedly connected to a fourth insulation board 11. The inner wall of the third insulation board 10 is fixedly connected to a supporting guide rail 12. The inside of the drying chamber 2 is provided with a fruit and vegetable tray 13. The lower surface of the fruit and vegetable tray 13 is fixedly connected to a fixed guide wheel 14. The top of the drying chamber 2 is movably provided with a top cover 16. The corners of the outer surfaces of the drying chamber 2 and the top cover 16 are provided with opening and closing buckles 17. The inside of the top cover 16 is provided with a dehumidification channel 18.
[0024] Specifically, the end of the heat conduction channel 4 away from the air source heat pump host 1 is connected to the end of the heat conduction interface 5 away from the drying box 2. The inner cavity of the drying box 2 is connected to the interior of the air source heat pump host 1 through the heat conduction channel 4 and the heat conduction interface 5.
[0025] Specifically, the inner diameter of the heat-conducting interface 5 is smaller at the end near the drying oven 2, and the inner diameter of the heat-conducting interface 5 is larger at the end near the heat-conducting channel 4.
[0026] Specifically, four support legs 6 are fixedly connected to the bottom corners of the drying oven 2.
[0027] Specifically, the support rails 12 are symmetrically arranged on the inner wall of the third insulation plate 10, and the support rails 12 are linearly arranged along the inner wall of the third insulation plate 10.
[0028] Specifically, a handle 15 is fixedly connected to the outer surface of the fruit and vegetable tray 13, and the outer surface of the fixed guide wheel 14 is adapted to the interior of the support guide rail 12.
[0029] The working principle and beneficial effects of the above embodiments.
[0030] In use, place fruits and vegetables into the fruit and vegetable tray 13, then move the fixed guide wheels 14 at the bottom of the fruit and vegetable tray 13 along the support guide rail 12 until the fruit and vegetable tray 13 is completely placed into the drying chamber 2. Close the opening and closing door 7, and turn on the air source heat pump host 1 through the controller 3. The air source heat pump host 1 uses the reverse Carnot principle, where gaseous Freon is pressurized by the compressor into a high-temperature, high-pressure gas, which enters the condenser. The refrigerant condenses and liquefies, releasing high-temperature heat. The high-temperature heat passes through the heat conduction channel 4 and the heat conduction interface 5 into the drying chamber 2 to dry the fruits and vegetables on the fruit and vegetable tray 13. The water vapor generated during the drying process is discharged through the dehumidification channel 18 and passes through the first insulation plate 8, the second insulation plate 9, the third insulation plate 10, and the fourth insulation plate 11, allowing heat to enter the drying chamber 2 from inside the air source heat pump host 1. During the process, the heat is not easily lost, and the drying oven 2 has a good heat preservation effect, thereby reducing the energy consumption of the air source heat pump host 1. By setting the heat conduction interface 5 to a structure that is wider at the front and narrower at the back, with a smaller inner diameter at the end of the heat conduction interface 5 near the drying oven 2 and a larger inner diameter at the end of the heat conduction interface 5 near the heat conduction channel 4, the force of air transfer is increased, and the heat will be blown more forcefully towards the drying oven 2, increasing the flow rate of high-temperature gas in the drying oven 2, thereby improving the drying efficiency. By setting fixed guide wheels 14 on the lower surface of the fruit and vegetable tray 13, the fixed guide wheels 14 roll in the support guide rail 12, making it easier to put in and take out the fruit and vegetable tray 13, which is convenient for operation. The top of the drying oven 2 is movably set with a top cover 16, which is opened and closed by opening and closing buckles 17 set at its four corners.
