[0002] Rice dryers mainly use a heat pump to heat air and circulate the hot air within the drying equipment. The hot air removes moisture from the rice, thus achieving the drying process.

[0003] When the heat pump unit on the dryer is working, it needs to draw in outside air for heating. The outside air contains dust and impurities. The heat pump unit is equipped with a dustproof screen to isolate the dust and impurities. However, this dustproof screen structure requires cleaning after long-term use. Cleaning requires disassembling the screws connecting the dustproof screen and the unit in order to remove the dustproof screen for cleaning. This design has low efficiency in cleaning and maintaining the dustproof screen. Utility Model Content

[0022] Please see Figure 1-5 This utility model provides an embodiment of a rice dryer that facilitates cleaning of the filter screen, comprising a main component assembly 01, which includes a heat pump main unit housing 11 and a dustproof plate 12. The main component assembly 01 is externally provided with a quick-connect component assembly 02 and a limiting component assembly 03. The quick-connect component assembly 02 is used to connect the heat pump main unit housing 11 and the dustproof plate 12. The quick-connect component assembly 02 includes an upper horizontal bar 21, with a vertical connecting rod 22 and a locking block 23 at its bottom. A spring 24 is externally provided on the vertical connecting rod 22, and a housing 25 is externally provided on the spring 24. A handle 26 is externally provided on the upper horizontal bar 21. A lower guide plate 27 is externally provided on the bottom of the dustproof plate 12, and a U-shaped handle 28 is externally provided on the dustproof plate 12. The limiting component assembly 03 includes an upper housing 31, with a knob 32 on one side of the upper housing 31, and a threaded rod 33 connected to the side of the knob 32.

[0023] The quick-connect component group 02 has three sets of components: the upper horizontal bar 21, the vertical connecting rod 22, the locking block 23, the spring 24, and the outer shell 25. The three sets of components are located at the top of the dustproof plate 12. The outer shell 25 is connected to the surface of the heat pump host housing 11. The vertical connecting rod 22 slides in contact with the outer shell 25 through a through hole.

[0024] The vertical connecting rod 22 is connected between the upper horizontal rod 21 and the locking block 23. One end of the spring 24 is connected to the locking block 23, and the other end of the spring 24 is connected to the outer shell 25. The locking block 23 slides in contact with the outer shell 25 through the sliding groove.

[0025] The handle 26 is connected to the upper crossbar 21 through a through groove. The surface of the handle 26 is provided with anti-slip texture. One side of the locking block 23 is set as an arc. The locking block 23 is in contact with the surface of the dustproof plate 12.

[0026] The upper housing 31 is connected to the surface of the heat pump main housing 11, the surface of the knob 32 is provided with anti-slip texture, and one end of the knob 32 is connected to the threaded rod 33.

[0027] The threaded rod 33 is connected to the upper housing part 31 by threads.

[0028] The bottom of the outer casing 25 contacts the dustproof plate 12. Two sets of U-shaped handles 28 are provided, and the two sets of U-shaped handles 28 are symmetrically distributed on both sides of the dustproof plate 12. The U-shaped handles 28 are connected to the dustproof plate 12. The lower guide plate 27 is connected to the heat pump main unit casing 11. The lower guide plate 27 is used to slide in contact with the bottom of the dustproof plate 12.

[0029] Working principle: In this device, the dustproof plate 12 is installed at the ventilation opening of the heat pump main unit housing 11. The connection between the dustproof plate 12 and the heat pump main unit housing 11 is made through the quick-connect component assembly 02. When installing the dustproof plate 12 onto the ventilation opening of the heat pump main unit housing 11, the dustproof plate 12 is placed directly onto the sliding groove of the lower guide plate 27, allowing the dustproof plate 12 to be pushed towards the heat pump main unit housing 11 on the lower guide plate 27. During the pushing process, one side of the dustproof plate 12 will engage with the arc-shaped structure of the locking block 23, and as the dustproof plate 12 continues to move forward, it will push against the airflow. When the locking block 23 is released, the locking block 23, the vertical connecting rod 22, and the upper horizontal rod 21 will move upward, the spring 24 will retract, and the locking block 23 will move into the sliding groove of the outer shell 25. When the dustproof plate 12 contacts the heat pump main unit housing 11, the spring 24 will release its stored force to push the locking block 23 out. The locking block 23 will then contact the surface of the dustproof plate 12. At this time, the locking block 23 and the heat pump main unit housing 11 cooperate to clamp the dustproof plate 12 in the middle, thereby completing the connection between the dustproof plate 12 and the heat pump main unit housing 11. In this way, the heat pump main unit housing 11 and the dustproof plate 12 will be connected.

[0030] When the dust cover 12 needs to be removed from the heat pump main unit housing 11 for cleaning, by pulling the handle 26 on the upper crossbar 21, the handle 26 is moved upward, and the upper crossbar 21 will slide upward in the upper housing 31. When the upper crossbar 21 is fully moved to the top of the slide groove in the upper housing 31, the locking block 23 will be located inside the slide groove of the outer housing 25. At this time, turn the knob 32 to rotate the threaded rod 33, so that one end of the threaded rod 33 extends into the upper housing 31 through the thread, and the upper crossbar 21 will... Blocked by the threaded rod 33, the spring 24 is prevented from releasing its stored force. Then, the dust cover 12 can be slid off from the lower guide plate 27, completing the disassembly and separation of the dust cover 12 and the heat pump main unit housing 11. With this design, when removing the dust cover 12 from the heat pump main unit housing 11, it is not necessary to keep pulling the handle 26 upward. After pulling the upper crossbar 21 to the top of the upper housing part 31 slide groove, the threaded rod 33 is rotated to block the upper crossbar 21 from moving downward, so that the locking block 23 can always remain in the outer housing 25.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
