[0002] Current dryers are equipped with compressors, evaporators, and condensers at the air inlet. They draw in outside air and dry and dehydrate it. The dry, hot air dries the grain in the storage bin, and the air in the storage bin is exhausted by a ventilation fan. This allows the dry, hot air to remove the moisture from the grain, enabling it to be stored dehydrated.

[0003] Because existing dryers only have one air inlet and one air outlet path, they can only blow out high-temperature gas and cannot blow out air of different temperatures according to usage requirements. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1 to 5 As shown, this application embodiment provides a dryer, including a frame 10, which is enclosed on all four sides. A first partition 20 is provided inside the frame 10, dividing the internal space of the frame 10 into a left cavity 11 and a right cavity 12. The left cavity 11 and right cavity 12 are used to install different components. The left cavity 11 is further divided into an upper cavity 111 and a lower cavity 112 by a divider. A sensible heat exchanger 30 is provided in the upper cavity 111. It should be understood that the sensible heat exchanger 30 achieves heat transfer through a sensible heat exchange core. When indoor exhaust air and fresh air flow through the core of the sensible heat exchanger 30 in a cross-flow manner, due to the temperature difference on both sides of the airflow divider, the two airflows exhibit heat transfer when passing through the divider, thereby realizing the sensible heat exchange process.

[0024] The sensible heat exchanger 30 divides the upper chamber 111 into four non-communicating chambers: a first chamber 1111, a second chamber 1112, a third chamber 1113, and a fourth chamber 1114. This creates different gas flow paths. A first fan 40, connected to the first chamber 1111, is mounted on the frame 10. Here, the first fan 40 is a dehumidifying fan. The lower chamber 112 is connected to the second chamber 1112, meaning that gas from the second chamber 1112 can flow into the lower chamber 1112. The cavity 1113 is connected to the right cavity 12, so that the gas in the right cavity 12 can flow into the third cavity 1113. The top of the fourth cavity 1114 is provided with a first opening 13 for introducing indoor gas. The lower cavity 112 is provided with a second fan 50 for exhausting hot air. The right cavity 12 is provided with a third fan 60 for exhausting cold air. The top of the right cavity 12 is provided with a vent 14 for introducing fresh air.

[0025] By setting up a left cavity 11 and a right cavity 12, and dividing the left cavity 11 into an upper cavity 111 and a lower cavity 112, and by setting up a first fan 40, a second fan 50 and a third fan 60 in different cavities, the gas forms three flow paths inside the frame 10, each corresponding to one of the three fans, to achieve different exhaust functions of the dryer. This results in good performance and a more compact overall structure.

[0026] Specifically, the first partition 20 is provided with a second opening 21, which is triangular in shape. The third cavity 1113 and the right cavity 12 are connected through the second opening 21. Gas entering from the right cavity 12 can enter the third cavity 1113 through the second opening 21.

[0027] In one embodiment, the baffle includes a microchannel condenser 70 and a second partition 80. The microchannel condenser 70 separates the second cavity 1112 and the lower cavity 112. When the gas in the second cavity 1112 flows through the microchannel condenser 70, the gas is heated by the microchannel condenser 70 and finally discharged by the second fan 50. At this time, the gas discharged by the second fan 50 is a high-temperature gas. The second partition 80 separates the third cavity 1113 from the lower cavity 112. The third cavity 1113 and the lower cavity 112 are not connected.

[0028] In one embodiment, an electric heating assembly 90 is also provided on one side of the second fan 50. The electric heating assembly 90 can be a group of electrically powered heating components. The electric heating assembly 90 plays an auxiliary role. When the gas is introduced into the lower cavity 112 through the microchannel condenser 70, if the temperature is insufficient, the electric heating assembly 90 heats up, causing the gas temperature to continue to rise, and finally it is discharged through the circulating fan. Here, the electric heating assembly 90 plays an auxiliary heating role.

[0029] In one embodiment, a finned evaporator 100 is disposed within the right cavity 12, and the finned evaporator 100 is connected to the third fan 60. It should be understood that the main functions of the finned evaporator 100 include accelerating evaporation and cooling rates, increasing heat dissipation area, and improving cooling efficiency. Specifically, the fin arrangement and design of the finned evaporator 100 can accelerate the evaporation and cooling rate of the refrigerant, improving the cooling efficiency and cooling capacity of the equipment. Furthermore, the densely packed aluminum fins of the finned evaporator 100 can increase the heat dissipation area, thereby achieving a faster heat dissipation effect and allowing the refrigerant to evaporate more quickly. This ensures that the air discharged from the third fan 60 is cold air below room temperature.

[0030] Below the finned evaporator 100, at the bottom of the right cavity 12, a compressor 110 is also installed. The compressor 110, the second fan 50, and the electric heating group 90 are all located at the bottom of the frame 10, making the overall structure more compact. Furthermore, a door 120 is installed below the second fan 50, and an electrical control box 130 is installed on the inner wall of the door 120. The electrical control box 130 is electrically connected to each component and is used to control the operation of each component. When the door 120 is closed, the electrical control box 130 is located inside the right cavity 12. Placing the electrical control box 130 on the door 120 and inside the frame 10 makes the overall spatial layout more compact.

[0031] The gas flow path of the dryer in this application is as follows: fresh air is introduced into the right cavity 12 through the vent 14, and is divided into two paths in the right cavity 12. One path passes through the finned evaporator 100 and is discharged from the third fan 60. At this time, cold air is discharged. The other path enters the third cavity 1113 through the second opening 21, then enters the sensible heat exchanger 30, enters the first cavity 1111, and is discharged from the first fan 40. The air in the room enters the fourth cavity 1114 through the first opening 13, then enters the second cavity 1112 through the sensible heat exchanger 30, and enters the lower cavity 112 through the microchannel condenser 70. Finally, it is discharged under the action of the second fan 50. In this way, the dryer realizes the exhaust function for multiple different needs.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
