[0037] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as "center", "up", "down", "front", "back", "bottom", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the related art, the fresh air inlet is located on the side wall of the drying room heating chamber, and the circulating fan forms negative pressure to automatically suck in fresh air from the fresh air inlet. When the materials are unevenly installed in the drying room of the drying room or the speed of the circulating fan in the drying room is low, the circulating fan will not be able to suck in a large amount of fresh air into the drying room to dehumidify, which will cause the materials to be damaged during the drying process.

[0042] In order to solve the above technical problems, a fresh air inlet connected to the outside atmosphere and a return air inlet connected to the drying chamber are arranged in the first chamber of the heating chamber, and the fresh air valve is movably arranged in the first chamber, so that the fresh air valve selectively opens or closes the fresh air inlet or the return air inlet, so that the return air inlet can be closed when the fresh air valve opens the fresh air inlet, so that the whole drying room can generate a slight positive pressure. Then, the circulating fan can inhale a large amount of fresh air from the fresh air inlet into the drying room for dehumidification, which can avoid the excessive humidity in the drying room affecting the drying of materials, and is conducive to improving the drying effect and quality of the drying room.

[0043] The structure of the drying room in the embodiment of the present application is described below.

[0044] The drying room provided in the embodiment of the present application includes: a drying chamber, a heating chamber, a circulating fan and a fresh air valve.

[0045] See also Figure 1 , Figure 1 A three-dimensional diagram of a drying room provided in an embodiment of the present application. For ease of description, a coordinate system is established for the drying room 100. The length direction of the drying room 100 is the X-axis direction. The two directions perpendicular to the X-axis direction are the Z-axis direction and the Y-axis direction. The Z-axis direction is perpendicular to the Y-axis direction. Exemplarily, the width direction of the drying room 100 is the Y-axis direction, and the height direction of the drying room 100 is the Z-axis direction. Of course, in other examples, the width direction of the drying room 100 is the Z-axis direction, and the height direction of the drying room 100 is the Y-axis direction. In the following description, the length direction of the drying room 100 is the X-axis direction, the width direction of the drying room 100 is the Y-axis direction, and the height direction of the drying room 100 is the Z-axis direction.

[0046] See also Figure 2 , Figure 2 This is a cross-sectional view of a drying room provided in an embodiment of the present application. Figure 2 , the heating chamber 2 is located at one side of the drying chamber 1. The circulating fan 3 is located in the heating chamber 2. Thus, the circulating fan 3 can drive the airflow to flow in the heating chamber 2. Exemplarily, the drying chamber 1 is in the shape of a cuboid.

[0047] The circulating fan 3 divides the heating chamber 2 into a first chamber 21 and a second chamber 22. The first chamber 21 has a fresh air inlet 211 connected to the outside atmosphere, and has a return air inlet 212 connected to the drying chamber 1. Thus, the outside atmosphere can enter the first chamber 21 through the fresh air inlet 211, and the airflow in the drying chamber 1 can flow into the heating chamber 2 through the return air inlet 212.

[0048] The second chamber 22 has an air outlet 221 communicating with the drying chamber 1 , so that the airflow in the second chamber 22 can flow into the drying chamber 1 through the air outlet 221 .

[0049] The circulation fan 3 is used to drive the airflow from the return air port 212 and the fresh air port 211 to the air outlet 221. Therefore, the first chamber 21 is the negative pressure side of the circulation fan 3, and the second chamber 22 is the positive pressure side of the circulation fan 3. When the circulation fan 3 is started, the airflow flowing out of the return air port 212 and the airflow flowing out of the fresh air port 211 can be driven to flow to the air outlet 221, and then flow into the drying chamber 1 from the air outlet 221.

[0050] Please continue reading Figure 2 The fresh air valve 4 is movably disposed in the first chamber 21 to selectively open or close one of the fresh air inlet 211 and the return air inlet 212. Therefore, when the fresh air valve 4 closes the fresh air inlet 211, the return air inlet 212 is opened, which can prevent the circulation fan 3 from introducing fresh air from the fresh air inlet 211. When the fresh air valve 4 closes the return air inlet 212, the fresh air valve 4 is opened. At this time, the pressure at the fresh air valve 4 is relatively large, and the entire drying room 100 can generate a slight positive pressure. The circulation fan 3 can inhale a large amount of fresh air from the fresh air inlet 211 and send it into the drying chamber 1, which is conducive to the discharge of humid air in the drying chamber 1.

[0051] According to the drying room 100 of the embodiment of the present application, a fresh air inlet 211 connected to the outside atmosphere and a return air inlet 212 connected to the drying room 1 are arranged in the first chamber 21 of the heating chamber 2, and the fresh air valve 4 is movably arranged in the first chamber 21, so that the fresh air valve 4 selectively opens or closes the fresh air inlet 211 or the return air inlet 212, so that the return air inlet 212 can be closed when the fresh air valve 4 opens the fresh air inlet 211, so that the entire drying room 100 can generate a slight positive pressure. In addition, the circulating fan 3 can inhale a large amount of fresh air from the fresh air inlet 211 into the drying room 1 for dehumidification, which can prevent the excessive humidity in the drying room 1 from affecting the drying of materials, and is conducive to improving the drying effect and quality of the drying room 100.

[0052] See also Figure 3 , Figure 3 for Figure 2The fresh air valve 4 is rotatably arranged in the first chamber 21. Thus, the fresh air valve 4 can selectively open or close one of the fresh air inlet 211 and the return air inlet 212 by controlling the rotation of the fresh air valve 4, which has a simple structure and convenient control.

[0053] For example, the fresh air valve 4 can be rotatable by means of a hinge.

[0054] In other embodiments, the fresh air valve 4 is slidably disposed in the first chamber 21. Thus, the fresh air valve 4 can selectively open or close one of the fresh air inlet 211 and the return air inlet 212 by controlling the sliding of the fresh air valve 4, which has a simple structure and convenient control.

[0055] In some embodiments, the fresh air inlet 211 and the return air inlet 212 are located on the same side, and one rotatable end of the fresh air valve 4 is located between the fresh air inlet 211 and the return air inlet 212 .

[0056] Please continue reading Figure 3 In some implementations, the central axis of the fresh air outlet 211 is perpendicular to the central axis of the return air outlet 212. Therefore, on the one hand, when the fresh air valve 4 rotates, the return air outlet 212 can be closed while the fresh air outlet 211 is opened, or the fresh air outlet 211 can be closed while the return air outlet 212 is opened. Thus, the rotation angle of the fresh air valve 4 can be reduced, and the response speed of the control can be improved, and the energy loss can be reduced. On the other hand, it is convenient to set the fresh air outlet 211 and the return air outlet 212, which can reduce the difficulty of processing.

[0057] The central axis of the fresh air outlet 211 refers to a straight line passing through the center of the fresh air outlet 211 and perpendicular to the plane where the fresh air outlet 211 is located. The central axis of the return air outlet 212 refers to a straight line passing through the center of the return air outlet 212 and perpendicular to the plane where the return air outlet 212 is located.

[0058] In other embodiments, the central axis of the fresh air outlet 211 is at a certain angle to the central axis of the return air outlet 212. For example, the angle between the central axis of the fresh air outlet 211 and the central axis of the return air outlet 212 can be an acute angle. Thus, the rotation angle of the fresh air valve 4 can be further reduced, and the response speed of the rotation control can be improved.

[0059] As another example, the angle between the central axis of the fresh air outlet 211 and the central axis of the return air outlet 212 may be an obtuse angle.

[0060] See also Figure 4 , Figure 4The cross-sectional view of the drying room and the heat pump drying unit provided in the embodiment of the present application. The heating chamber 2 has a first wall plate 23. The drying room 100 also includes a fresh air duct member 5. The fresh air duct member 5 is fixed to the first wall plate 23. Thus, the fresh air duct member 5 can be prevented from falling off.

[0061] Exemplarily, the first wall plate 23 is provided with an opening matched with the fresh air duct member 5 , and the fresh air duct member 5 can pass through the opening to be fixed on the first wall plate 23 .

[0062] Please continue reading Figure 4 The part of the fresh air duct member 5 located in the first chamber 21 has a fresh air port 211, and the fresh air duct member 5 has a fresh air inlet (not shown) for connecting with the outside atmosphere. Thus, the outside atmosphere can enter the fresh air duct member 5 through the fresh air inlet, and then flow into the first chamber 21 from the fresh air channel through the fresh air port 211, so that the circulation fan 3 can introduce fresh air into the drying chamber 1. At the same time, the fresh air duct member 5 can be provided to better arrange the position of the fresh air port 211.

[0063] Please continue reading Figure 4 The heating chamber 2 has a second wall plate 24 and a third wall plate 25. The second wall plate 24 is located on a side of the heating chamber 2 adjacent to the drying chamber 1. The second wall plate 24 and the third wall plate 25 are in a first direction (eg Figure 4 The return air port 212 is formed on the second wall plate 24, and the first direction is the arrangement direction of the heating chamber 2 and the drying chamber 1. This arrangement can reduce the length of the return air path of the drying chamber 1, so that the airflow in the drying chamber 1 can quickly flow back to the heating chamber 2, and the speed of the airflow circulation in the drying room 100 is increased, which is conducive to improving the drying efficiency of the drying room 100 for materials.

[0064] Please continue reading Figure 4 The first wall plate 23 is connected between the second wall plate 24 and the third wall plate 25, and the first wall plate 23 is located between the second wall plate 24 in the second direction (such as Figure 1 Thus, one end of the first wall plate 23 is connected to one end of the second wall plate 24 in the second direction, and the other end of the first wall plate 23 is connected to one end of the third wall plate 25 in the third direction.

[0065] The circulation fan 3 and the fresh air duct member 5 are in the third direction (such as Figure 4The fresh air outlet 211 is formed at one end of the fresh air duct member 5 away from the circulation fan 3 in the third direction. The return air outlet 212 is located on the side of the fresh air duct member 5 away from the circulation fan 3. The second direction and the third direction are perpendicular to the first direction. Thereby, it is convenient for the fresh air valve 4 to open or close one of the return air outlet 212 and the fresh air outlet 211. At the same time, by arranging the return air outlet 212 on the side of the fresh air duct member 5 away from the circulation fan 3, it is convenient for the airflow with higher humidity to flow out from the return air outlet 212 into the heating chamber 2.

[0066] See also Figure 4 In some implementations, the fresh air valve 4 is rotatably disposed on the second wall plate 24, and the rotation centerline of the fresh air valve 4 extends along the second direction. This arrangement facilitates the opening and closing of the fresh air outlet 211 or the return air outlet 212 by the fresh air valve 4.

[0067] In some embodiments, the opening degree of the fresh air valve 4 to the fresh air outlet 211 is negatively correlated with the opening degree of the fresh air valve 4 to the return air outlet 212. The opening degree of the fresh air valve 4 to the fresh air outlet 211 refers to the area of ​​the fresh air outlet 211 minus the area of ​​the area overlapping with the orthographic projection of the fresh air valve 4 at the fresh air outlet 211. The opening degree of the fresh air valve 4 to the return air outlet 212 refers to the area of ​​the return air outlet 212 minus the area of ​​the area overlapping with the orthographic projection of the fresh air valve 4 at the return air outlet 212. This arrangement allows the opening degree of the fresh air valve 4 to simultaneously control the area of ​​the fresh air outlet 211 and the return air outlet 212 that can be ventilated. The larger the opening degree of the fresh air valve 4, the more fresh air can flow out of the fresh air outlet 211, and the outflow of the return air outlet 212 gradually decreases. The smaller the opening degree of the fresh air valve 4, the less fresh air flows out of the fresh air outlet 211, and the outflow of the return air outlet 212 gradually increases.

[0068] See also Figure 4 In some embodiments, a heat pump drying unit is provided in the heating chamber 2, and the heat pump drying unit includes a condenser 8, and the condenser 8 can be located in the first chamber 21. This arrangement allows the airflow passing through the condenser 8 to be heated.

[0069] See also Figure 5 , Figure 5 A side view of a drying room provided in an embodiment of the present application. In some embodiments, the drying room 1 has a dehumidification outlet, and the drying room 100 further includes: a dehumidification valve 61. The dehumidification valve 61 is rotatably arranged at the dehumidification outlet. By providing the dehumidification outlet 6, the hot and humid air in the drying room 1 can be discharged from the dehumidification outlet 6, which is conducive to ensuring the drying effect of the drying room 100.

[0070] See also Figure 6 , Figure 6The cross-sectional view of the material rack and the drying room provided in the embodiment of the present application is shown in FIG. In some embodiments, the drying room 100 further includes a material rack 11. By providing the material rack 11, the material can be placed on the material rack 11.

[0071] In some embodiments, the drying room 100 further includes a wet-bulb temperature sensor and a controller. The wet-bulb temperature sensor can be connected to the controller. The wet-bulb temperature sensor is used to detect the actual temperature of the wet-bulb in the drying room 1.

[0072] In some embodiments, a wet-bulb temperature sensor is disposed in the drying chamber 1, and the wet-bulb temperature sensor can be wirelessly connected to the controller, which is helpful to improve the accuracy of the wet-bulb temperature sensor detection.

[0073] In addition, the controller can be used to control the operation of various components inside the drying room 100 , so that various components in the drying room 100 can be operated to realize various predetermined functions of the drying room 100 .

[0074] Based on the structure of the drying room 100 described above, the control method of the drying room 100 according to the embodiment of the present application is described below. The method is applied to a controller, which may be the controller described above.

[0075] See also Figure 7 , Figure 7 A flow chart for controlling the opening degree of a fresh air valve provided in an embodiment of the present application.

[0076] S1: Get the actual wet bulb temperature;

[0077] S2: according to the first difference interval in which the difference between the actual wet-bulb temperature and the first preset wet-bulb temperature is located, determining the preset opening degree of the fresh air valve 4 to the fresh air outlet 211 corresponding to the first difference interval, and there is a positive correlation between the preset opening degrees of the fresh air valve 4 to the fresh air outlet 211 corresponding to different first difference intervals and different first difference intervals;

[0078] S3: According to the determined preset opening degree of the fresh air valve 4 with respect to the fresh air outlet 211, the opening degree of the fresh air valve 4 with respect to the fresh air outlet 211 is controlled to be the preset opening degree.

[0079] Therefore, by setting the opening degree of the fresh air valve 4 to the fresh air outlet 211 corresponding to the first difference interval as the preset opening degree, the drying room 100 can determine the preset opening degree of the fresh air valve 4 to the fresh air outlet 211 corresponding to the first difference according to the first difference interval in which the difference between the actual wet-bulb temperature and the first preset wet-bulb temperature is located, so that the drying room 100 can control the preset opening degree of the fresh air valve 4 to the fresh air outlet 211 according to the fresh air demand in the drying room 1, which is beneficial to improving the drying efficiency of the drying room 100 and can effectively dehumidify.

[0080] For example, when the fresh air valve 4 is rotatably disposed in the first chamber 21. Figure 8 , Figure 8 A relationship diagram between the first difference interval and the first opening angle of the fresh air valve provided in the embodiment of the present application. For example, the multiple first difference intervals can be (0, a), [a, b), [b, c), [c, d), [d, e), where a <b<c<d<e。

[0081] See also Fig. 9 , Fig. 9 A schematic diagram of the first opening angle of the fresh air valve provided in the embodiment of the present application. When the first difference interval is (0, a), the first opening angle of the fresh air valve 4 can be 15°; when the first difference interval is [a, b), the first opening angle of the fresh air valve 4 can be 45°; when the first difference interval is [b, c), the first opening angle of the fresh air valve 4 can be 60°; when the first difference interval is [c, d), the first opening angle of the fresh air valve 4 can be 75°. For example, when it is determined that the first difference interval in which the difference △Tw between the actual wet-bulb temperature and the preset wet-bulb temperature is located is [a, b), the corresponding first opening angle of the fresh air valve 4 is obtained to be 45°, and the fresh air valve 4 is controlled to rotate 45°.

[0082] See also Fig.10 , Fig.10 A flow chart of controlling the rotation angle of a dehumidification valve provided in an embodiment of the present application. S1: obtaining the actual wet bulb temperature;

[0083] S2: According to the second difference interval in which the difference between the actual wet-bulb temperature and the second wet-bulb preset temperature lies, determine the second opening angle of the dehumidification valve 61 corresponding to the second difference interval, and the second opening angle of the dehumidification valve 61 corresponding to different second difference intervals is positively correlated with the different second difference intervals.

[0084] S3: According to the determined second opening angle of the dehumidification valve 61 , the dehumidification valve 61 is controlled to rotate to the second opening angle.

[0085] Among them, the value range of the opening angle is 0-90°.

[0086] Therefore, by setting the second opening angle of the dehumidification valve 61 corresponding to the second difference interval, the drying room 100 can determine the second opening angle of the dehumidification valve 61 corresponding to the second difference interval according to the second difference interval in which the difference between the actual wet-bulb temperature and the preset wet-bulb temperature is located, so that the drying room 100 can control the rotation angle of the dehumidification valve 61 according to the fresh air demand of the drying materials in the drying room 100200, which is beneficial to improving the energy efficiency and drying efficiency of the drying room 100.

[0087] Exemplarily, the multiple second difference intervals can be (0, a), [a, b), [b, c), [c, d), [d, e) respectively, where a < b < c < d < e. When the second difference interval is (0, a), the second opening angle of the moisture exhaust valve 61 can be 15°; when the second difference interval is [a, b), the second opening angle of the moisture exhaust valve 61 can be 45°; when the second difference interval is [b, c), the second opening angle of the moisture exhaust valve 61 can be 60°; when the second difference interval is [c, d), the second opening angle of the moisture exhaust valve 61 can be 75°. For example, when it is determined that the difference △Tw between the actual wet-bulb temperature and the preset wet-bulb temperature is in the second difference interval [a, b), and the corresponding second opening angle of the moisture exhaust valve 61 is obtained as 45°, then the moisture exhaust valve 61 is controlled to rotate 45°.

[0088] In some embodiments, the moisture exhaust valve 61 and the fresh air valve 4 operate synchronously. Such a setting can accurately control the moisture exhaust amount and the fresh air intake amount of the drying chamber 100, which is beneficial to reducing the energy consumption of the drying chamber 100.
