Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air outlet structure and a ceiling-mounted unit having the same. Background Technology

[0002] Currently, the air duct structure of floor-standing and ceiling-mounted air conditioners generally involves the air outlet components of the upper and lower volutes of the fan passing through a middle partition to form the air duct opening. However, the connection structure between the upper and lower volutes is limited, which cannot guarantee the stability of the connection between the upper and lower volutes. This makes the assembly structure more complicated during the installation and use of the volute structure, and the connection between the upper and lower volutes is prone to loosening. Vibration and noise are easily generated at the air outlet, affecting the user experience. Summary of the Invention

[0003] In view of this, the present invention aims to propose an air outlet structure and a seated hoist having the same. By improving the air duct structure of the seated hoist, an integrated metal upper baffle is set on the middle partition, which together with the U-shaped air outlet of the lower volute in the volute assembly forms the air outlet. The upper volute is completely confined to one side of the middle partition, which simplifies the setting structure of the volute assembly, facilitates the installation of the volute assembly, and avoids collision between the volute assembly and the middle partition during air outlet, thereby reducing noise.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] An air outlet structure, comprising:

[0006] A partition plate with a through opening and an upper wind deflector plate above one side of the through opening, the upper wind deflector plate being integrally formed with the partition plate;

[0007] A volute assembly, comprising an upper volute and a lower volute, wherein the upper volute and the lower volute are detachably connected;

[0008] The lower volute includes a mounting portion and an air outlet portion, which are respectively disposed on opposite sides of the through opening on the middle partition. The air outlet portion is disposed below the upper wind deflector, and the air outlet portion and the upper wind deflector form the air outlet of the volute assembly. The upper volute is disposed above the mounting portion of the lower volute.

[0009] The air outlet structure described in this invention improves the air duct structure of the ceiling-mounted air conditioner by setting an integrated upper baffle on one side of the middle partition, which forms an air duct opening with the air outlet of the lower volute in the volute assembly. The upper volute is completely confined to one side of the middle partition, simplifying the setting structure of the volute assembly, facilitating the installation of the volute assembly, reducing noise sources, and ensuring user comfort.

[0010] Furthermore, the upper wind deflector is arranged in an upward curved arc or zigzag shape from one end near the middle partition to the other end, and clearance grooves are provided on the middle partitions at both ends of the upper wind deflector, the clearance grooves being connected to the through opening.

[0011] This design improves the ease of installation of the lower volute, ensures the airtightness of the air outlet formed by the lower volute and the upper baffle plate, and reduces abnormal noise. At the same time, it increases the air outlet area, ensuring the smoothness and efficiency of air outlet for the crane volute assembly.

[0012] Furthermore, the air outlet includes a first side plate, a second side plate, and a bottom plate. The first side plate and the second side plate are respectively disposed at opposite ends of the bottom plate, and the upper ends of the first side plate and the second side plate extend beyond the upper edge of the upper wind deflector.

[0013] This setup has a simple structure, is easy to assemble, improves installation efficiency, and ensures the air outlet's airflow performance.

[0014] Furthermore, the width of the opening at the upper end of the first side plate and the second side plate is smaller than the width of the upper windshield.

[0015] This design ensures the airtightness and stability of the connection between the air outlet and the upper baffle, reduces the number of parts, and guarantees the air outlet's performance.

[0016] Furthermore, the upper edges of the first side plate and the second side plate are arc-shaped, and the first side plate and the second side plate are curved downward or inclined from the end away from the mounting part to the end closer to the mounting part.

[0017] This design, by incorporating a smaller clearance groove, allows the air outlet to pass through the through-hole for assembly and connection, enhancing the strength of the upper baffle connection and preventing deformation of the middle partition or upper baffle connection.

[0018] Furthermore, the upper windshield and the middle partition are arranged in an arc-shaped transition at the connection point.

[0019] This design prevents the upper wind deflector from deforming due to concentrated stress during the installation of the lower volute, further improving the airflow effect of the air outlet formed by the lower volute and the upper wind deflector.

[0020] Furthermore, a receiving groove is provided on each of the first side plate and the second side plate, the receiving groove being used to accommodate the connecting end of the upper windshield.

[0021] This design further improves the sealing performance of the connection between the air outlet and the upper baffle, as well as the ease of assembly, thereby enhancing the airflow effect and preventing abnormal noises from the air outlet.

[0022] Furthermore, a limiting groove is provided at the end of the receiving groove away from the mounting part, and a limiting block is provided at the end of the upper wind deflector away from the middle partition plate. The limiting block can be engaged and limited into the limiting groove.

[0023] This design further improves the sealing and stability of the connection between the air outlet and the upper baffle, preventing vibration and abnormal noise or deformation of the connection of the air outlet structure during use, extending its service life and improving the user experience.

[0024] Furthermore, a first mounting plate is provided on the lower volute, and the first mounting plate and the upper wind deflector are respectively provided on opposite sides of the middle partition. The first mounting plate is detachably connected to the middle partition. A first limiting plate is provided at one end of the upper volute near the middle partition, and the first limiting plate is detachably and sealingly connected to the middle partition.

[0025] This design further improves the ease of assembly between the volute assembly and the middle partition, ensures the air outlet effect of the air outlet structure, and enhances the user experience.

[0026] Compared with existing technologies, the air outlet structure described in this invention has the following advantages:

[0027] (1) The air outlet structure described in this invention improves the air duct structure of the pedestal crane by setting an integrated upper baffle on the middle partition, which forms an air outlet with the air outlet of the lower volute passing through the middle partition, greatly reducing the air volume loss or noise problem caused by excessive gaps in the connection of the volute assembly.

[0028] (2) The air outlet structure described in this invention improves the air duct structure of the ceiling crane, making it easier to install the upper and lower volute structures, facilitating assembly, ensuring stable connection, and providing reliable air outlet.

[0029] Another object of the present invention is to provide a seated crane having an air outlet structure as described above.

[0030] The advantages of the aforementioned pedestal crane over the existing technology are the same as those of the air outlet structure, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0040] To make the technical means and objectives and effects of the present invention easier to understand, the embodiments of the present invention will be described in detail below with reference to specific illustrations.

[0041] Example 1

[0042] The specific components of the suspended air conditioner structure described in this embodiment are largely the same as those of a conventional suspended air conditioner. Specifically, the suspended air conditioner includes shell components such as a panel and a middle frame, air guides, a base plate 1, and internal components such as a partition plate 3 for fixing the volute assembly 2, heat exchange coils, a fan, and a motor. In existing suspended air conditioners, because they can be both seated and suspended, the stability of the partition plate 3 and the volute assembly 2 affects the reliability of the unit, as well as its noise and airflow. In existing technologies, the air outlet side of the volute assembly 2 is typically extended to the side of the partition plate 3 where the heat exchange coil is located. Both the upper and lower parts of the volute assembly must pass through the connection port on the partition plate 3. This connection port has limited space, making assembly inconvenient. Furthermore, the air outlet structure of the volute assembly 2 has multiple contact points with the partition plate 3, which can easily generate collision noise during use, affecting the user experience.

[0043] like Figures 1-6 As shown, the present invention discloses an air outlet structure, comprising:

[0044] A middle partition 3 is provided with a through opening 7, and an upper wind baffle 5 is provided above one side of the through opening 7. The upper wind baffle 5 is integrally formed with the middle partition 3.

[0045] The volute assembly 2 includes an upper volute 8 and a lower volute 9, which are detachably connected.

[0046] The lower volute 9 includes a mounting part 15 and an air outlet 6. The mounting part 15 and the air outlet 6 are respectively disposed on opposite sides of the through-hole 7 on the middle partition 3. The air outlet 6 is disposed below the upper wind deflector 5, and the air outlet 6 and the upper wind deflector 5 form the air outlet of the volute assembly 2. The upper volute 8 is disposed above the mounting part 15 of the lower volute 9.

[0047] The air outlet structure disclosed in this invention improves the design of the partition plate 3 and the volute assembly 2 on the pedestal crane structure. By transferring part of the air outlet structure of the volute assembly 2 to the volute assembly 2, it avoids the need for both the upper volute 8 and the lower volute 9 of the volute assembly 2 to pass through the through-hole 7 on the partition plate 3. During installation, the lower volute 9 is installed first. One end of the air outlet 6 of the lower volute 9 is inserted through the through-hole 7 into the side of the base plate 1 where the heat exchange coil is installed. After the lower volute 9 is installed in place, it is fixedly connected to the base plate 1 and / or the partition plate. The air outlet 6 of the lower volute 9 abuts against the upper baffle plate 5 integrally formed by the partition plate 3 to form a circumferentially closed air outlet. After the fan and other structures are assembled, the upper volute 8 is fixed above the mounting part 15 of the lower volute 9. The upper volute 8 and the mounting part 15 of the lower volute 9 and / or the partition plate 3 are detachably connected. Therefore, the air outlet structure described in this application, through the upper baffle 5 integrally formed on the middle partition 3, only requires the air outlet 6 of the lower volute 9 to pass through the through-hole 7 during assembly, which improves assembly efficiency. Furthermore, since the upper baffle 5 and the middle partition 3 are integrally formed, the contact position between the air outlet structure of the volute assembly 2 and the middle partition is reduced, avoiding vibration and collision between the upper volute and the through-hole 7 during use, reducing noise sources, and improving the user experience.

[0048] The air outlet structure described in this invention improves the air duct structure of the ceiling-mounted air conditioner by setting an integrated upper baffle on one side of the middle partition 3, which together with the air outlet 6 of the lower volute 9 in the volute assembly 2 forms an air duct opening. The upper volute 8 is entirely confined to one side of the middle partition 3, simplifying the structure of the volute assembly 2, facilitating its installation, reducing noise sources, and ensuring user comfort.

[0049] As a preferred example of the present invention, the upper wind deflector 5 is arranged in an upward curved arc or zigzag shape from one end near the middle partition 3 to the other end, and a relief groove 13 is provided on the middle partition 3 at both ends of the upper wind deflector 5, and the relief groove 13 is connected to the through opening 7.

[0050] This design increases the air outlet area formed by the lower volute 9 and the upper baffle plate 5, ensuring smooth and efficient airflow from the volute assembly 2 of the crane. The design of the clearance groove 13 allows the air outlet 6 of the lower volute 9 to pass smoothly through the through-hole 7 and form a circumferentially closed air outlet with the upper baffle plate 5. The cross-section in the circumferential direction is perpendicular to the airflow direction, avoiding abnormal noise problems caused by air leakage.

[0051] This design not only improves the ease of installation of the lower volute 9 and ensures the airtightness of the air outlet 6 of the lower volute 9 and the air baffle 5 to form an air outlet, reducing abnormal noise; at the same time, it increases the air outlet area to ensure the smoothness and efficiency of air outlet of the volute assembly 2 of the crane.

[0052] As a preferred example of the present invention, the air outlet 6 includes a first side plate 601, a second side plate 602, and a bottom plate 603. The first side plate 601 and the second side plate 602 are respectively disposed at opposite ends of the bottom plate 603, and the upper ends of the first side plate 601 and the second side plate 602 extend beyond the upper edge of the upper wind deflector 5. As an example of the present invention, the air outlet 6 includes a first side plate 601, a second side plate 602, and a bottom plate 603 with a U-shaped design. The lower volute 9 is a plastic part. The first side plate 601 and the second side plate 602 of the air outlet 6 are distributed on both sides of the upper wind deflector 5 when passing through the through-hole 7. After the lower volute 9 is installed in place, the upper ends of the first side plate 601 and the second side plate 602 extend beyond the upper edge of the upper wind deflector 5. The first side plate 601, the bottom plate 603, and the second side plate 602 cooperate with the upper wind deflector 5 to form a circumferentially closed air outlet.

[0053] This setup has a simple structure, is easy to assemble, improves installation efficiency, and ensures the air outlet's airflow performance.

[0054] As a preferred example of the present invention, the width of the opening at the upper end of the first side plate 601 and the second side plate 602 is smaller than the width of the upper wind deflector 5. This arrangement ensures that after the lower volute 9 is installed in place, the opening end of the air outlet 6 is interference-fitted with the upper wind deflector 5, and the first side plate 601 and the second side plate 602 can deform outward under the action of the upper wind deflector 5, thus ensuring the airtight connection between the opening end of the air outlet 6 and the upper wind deflector 5.

[0055] This design ensures the airtightness and stability of the connection between the air outlet 6 and the upper baffle 5, reduces the number of parts, and guarantees the air outlet's airflow effect.

[0056] As a preferred example of the present invention, the upper edges of the first side plate 601 and the second side plate 602 are arranged in an arc shape, and the first side plate 601 and the second side plate 602 are arranged in a downward curved arc or inclined shape from the end away from the mounting part 15 to the end close to the mounting part 15.

[0057] When installing the lower volute 9, first pass the end of the air outlet 6 away from the mounting part 15 through the through-hole 7. At this time, the lower volute 9 is set at an angle. After the air outlet 6 passes through the through-hole 7 along the arc-shaped movement curve, the bottom surface of the air outlet 6 is installed in place. The end of the air outlet 6 near the mounting part 15 extends into the relief groove 13. The first side plate 601 and the second side plate 602 are interference-fitted to both ends of the upper wind deflector 5. This setting, by setting a small relief groove 13, can realize the assembly connection of the air outlet 6 through the through-hole 7, enhance the strength of the connection of the upper wind deflector 5, and avoid deformation of the middle partition 3 or the upper wind deflector 5 connection.

[0058] As a preferred example of the present invention, the upper windshield 5 and the middle partition 3 are arranged in an arc-shaped transition at the connection point.

[0059] This design prevents the upper wind deflector 5 from deforming due to concentrated stress during the installation of the lower volute 9, and further improves the air outlet effect formed by the lower volute 9 and the upper wind deflector 5.

[0060] Example 2

[0061] This invention discloses an air outlet structure, such as Figure 5 A receiving groove 604 is provided on the first side plate 601 and the second side plate 602. The receiving groove 604 is used to accommodate the connecting end of the upper windshield 5. Other structures are the same as in Embodiment 1.

[0062] As an example of the present invention, the two receiving grooves 604 are arranged symmetrically along the central plane of the bottom plate 603 in the vertical direction. Taking the receiving groove 604 on the first side plate 601 as an example, the receiving groove 604 is arc-shaped. The end of the receiving groove 604 away from the mounting part 15 extends out of the end of the first side plate 601. During the installation of the lower volute 9, after the end of the first side plate 601 away from the mounting part 15 extends into the through hole 7, the end of the receiving groove 604 away from the mounting part 15 is engaged with the upper wind deflector 5. As the air outlet 6 of the lower volute 9 is further advanced, the air outlet 6 moves along the assembly direction of the receiving groove 604 and the upper wind deflector 5. After the lower volute 9 is installed in place, the upper wind deflector 5 is confined within the receiving groove 604.

[0063] This design further improves the sealing between the air outlet 6 and the upper baffle 5, further enhancing the air outlet effect and preventing abnormal noises during air outlet.

[0064] As a preferred example of the present invention, such as Figure 6 As shown, a limiting groove 605 is provided at one end of the receiving groove 604 away from the mounting part 15, and a limiting block 501 is provided at one end of the upper wind deflector 5 away from the middle partition 3. The limiting block 501 can be engaged and limited to the limiting groove 605.

[0065] This design further improves the sealing and stability of the connection between the air outlet 6 and the upper baffle 5, avoids vibration and abnormal noise or vibration deformation at the connection of the air outlet structure during use, extends the service life of the air outlet structure of the present invention, and improves the user experience.

[0068] Specifically, during installation, the air outlet 6 of the lower volute 9 is first passed through the through-hole 7. After the lower volute 9 is installed in place, the first mounting plate 11 abuts against the surface of the back of the upper wind deflector 5 on the middle partition 3. A connecting device 4 is provided on the first mounting plate 11, and the connecting device 4 is detachably connected to the middle partition 3. For example, a mounting buckle 12 is provided on the first mounting plate 11, and a corresponding hole 14 is provided on the middle partition 3. The mounting buckle 12 can be engaged into the hole 14 for engagement and limiting.

[0069] As a preferred example of the present invention, two first mounting plates 11 are provided, and the two first mounting plates 11 are respectively provided on the first side plate 601 and the second side plate 602. This arrangement further ensures the convenience of installation and the stability of connection between the lower volute 9 and the middle partition plate 3.

[0071] Specifically, a sealing gasket or sealing sponge is provided on the side of the first limiting plate 10 near the middle partition plate 3, and a connecting hole is provided on the first limiting plate 10. The first limiting plate 10 and the middle partition plate 3 are detachably connected by connecting screws.
