Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an air outlet device and household appliance equipment. Background Technology

[0002] A fan is a common household appliance. When in cold air mode, a fan is similar to a regular fan, outputting cold air. When the fan is not in cold air mode, the heating device inside the fan works, turning the cold air generated inside the fan into warm air after passing through the heating device, and the fan outputs warm air.

[0003] In existing fans, the heating device is directly installed in the fan's outlet duct. When the fan outputs cold air, the heating device in the outlet duct will block the output flow of cold air, resulting in a small amount of cold air and low cold air output efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides an air outlet device and a household appliance to solve the problems existing in related technologies. The technical solution is as follows:

[0005] In a first aspect, embodiments of this application provide an air outlet device, comprising: a housing assembly having an air duct inside; a fan wheel disposed within the housing assembly for generating airflow through the air duct; a heater assembly movably disposed within the housing assembly; and a drive assembly disposed within the housing assembly for driving the heater assembly to move, such that the heater assembly has a first working position located within the air duct and a second working position moved outside the air duct.

[0006] In one embodiment, the housing assembly has a ventilation port, and a baffle plate for opening or closing the ventilation port is movably disposed inside the housing assembly; the ventilation port is connected to the air duct.

[0007] In one embodiment, a linkage component is further included, one end of which is connected to the heater assembly and the other end of which is connected to the wind deflector; wherein, when the drive assembly drives the heater assembly to move from the first working position to the second working position, the linkage component synchronously drives the wind deflector to move to close the ventilation port.

[0008] In one embodiment, the drive assembly includes: a motor and a screw disposed on the output end of the motor; the motor is installed inside the housing assembly, the screw is connected to the heater assembly in a transmission manner, and the motor drives the screw to rotate, thereby causing the heater assembly to translate along the axial direction of the screw.

[0009] In one embodiment, the heater assembly includes: a bracket and a heater disposed on the bracket; the bracket is provided with an internal thread portion, the internal thread portion being drivenly connected to the screw.

[0010] In one embodiment, the linkage component is a synchronizing rod, one end of which is movably connected to the bracket, and the other end of which is hinged to the wind deflector.

[0011] In one embodiment, the bracket is provided with a convex shaft, and the synchronizing rod is provided with an oblong hole that slides in accordance with the convex shaft.

[0012] In one embodiment, the housing assembly includes: an outer shell and a cover mounted on the outer shell; the outer shell is provided with a first guide groove corresponding to the movement path of the heater assembly, and the internal thread portion is movably disposed in the first guide groove; the air duct and the air exchange port are both disposed on the outer shell.

[0013] In one embodiment, a raised rib is provided on the side of the bracket opposite to the internal thread portion, and a second guide groove is provided on the cover to slide in cooperation with the raised rib.

[0014] Secondly, embodiments of this application provide a household appliance, including the aforementioned air outlet device.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following: In the air outlet device of this application, the heater assembly has a first working position located inside the air duct and a second working position moved outside the air duct. When the heater assembly moves from the first working position to the second working position under the driving action of the drive assembly, the airflow generated by the impeller can flow smoothly through the air duct. By reducing the obstruction of the cold air, the wind resistance of the cold air state can be reduced, the cold air volume can be increased, thereby improving the cold air outlet efficiency of the device.

Detailed Implementation

[0020] In the following description, only certain exemplary embodiments are briefly described to make the objects, features, and advantages of the present invention more apparent. As will be appreciated by those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1 like Figure 1 As shown, this embodiment provides an air outlet device, including: a housing assembly 1, wherein an air duct 2 is provided inside the housing assembly 1; a fan wheel 20, disposed inside the housing assembly 1, for generating airflow through the air duct 2; a heater assembly 4, movably disposed inside the housing assembly 1; and a drive assembly 5, disposed inside the housing assembly 1, for driving the heater assembly 4 to move, so that the heater assembly 4 has a first working position located inside the air duct 2 and a second working position moved outside the air duct 2.

[0023] In one embodiment, the heater assembly 4 is movably disposed within the housing assembly 1, and the drive assembly 5 can drive the heater assembly 4 to have a first working position located within the air duct 2 and a second working position located outside the air duct 2. See details below. Figure 6The impeller 20 is installed in the air duct 2 of the housing assembly 1 and serves as the air source for the air outlet device. It can generate airflow through the air duct 2. When the airflow does not flow through the heater 11, it blows cold air directly. When the airflow flows through the heater assembly 4, it can form hot air.

[0024] When the air outlet blows hot air, the heater assembly 4 is in the first working position. When the air outlet blows cold air, the heater assembly 4 moves to the second working position through the drive assembly 5. At this time, the heater assembly 4 is not in the air duct 2, and the airflow generated by the impeller 20 can flow smoothly through the air duct 2, which can reduce the resistance when blowing cold air, increase the cold air volume, and improve the cold air outlet efficiency.

[0025] Furthermore, such as Figure 2 As shown, the housing assembly 1 has an air exchange port 3, and a baffle 6 for opening or closing the air exchange port 3 is movably disposed inside the housing assembly 1; the air exchange port 3 is connected to the air duct 2.

[0026] In one embodiment, the housing assembly 1 has an interconnected air duct 2 and an air exchange port 3. The wind baffle 6 is rotatably disposed inside the housing assembly 1 and located at the opening of the air exchange port 3. When the wind baffle 6 rotates to different positions, it can control the open or closed state of the air exchange port 3. When the air outlet blows cold air, the wind baffle 6 can close the air exchange port 3 to reduce cold air leakage, thereby increasing the cold air volume and improving the cold air outlet efficiency.

[0027] Furthermore, it also includes a linkage component 7, one end of which is connected to the heater assembly 4 and the other end of which is connected to the wind deflector 6; wherein, when the drive component 5 drives the heater assembly 4 to move from the first working position to the second working position, the linkage component 7 synchronously drives the wind deflector 6 to move to close the ventilation port 3.

[0028] In one embodiment, the two ends of the linkage component 7 are respectively connected to the heater assembly 4 and the baffle 6. When the heater assembly 4 moves from the first working position to the second working position under the driving action of the drive component 5, the linkage component 7 can synchronously drive the baffle 6 to move to close the ventilation port 3, realizing the linkage control of the heater assembly 4 moving out of the air duct 2 and the baffle 6 closing the ventilation port 3. This reduces the wind resistance in the cold air state and reduces the cold air leakage, further increasing the cold air volume and improving the cold air outlet efficiency. When the heater assembly 4 moves from the second working position to the first working position under the driving action of the drive component 5, the linkage component 7 can synchronously drive the baffle 6 to move to open the ventilation port 3.

[0029] This air outlet device can simultaneously switch the position of the heater assembly 4 in the air duct 2 and open and close the air exchange port 3 by controlling the heater assembly 4 with only one action of the drive component 5. The control logic is simple and reliable and the structural design is reasonable. Compared with the method of using the motor 8 to control the wind deflector 6 separately, this air outlet device reduces the production cost.

[0030] Furthermore, such as Figure 3 As shown, the drive assembly 5 includes: a motor 8 and a screw 9 disposed on the output end of the motor 8; the motor 8 is installed inside the housing assembly 1, and the screw 9 is connected to the heater assembly 4 in a transmission manner. The motor 8 drives the screw 9 to rotate, thereby causing the heater assembly 4 to translate along the axial direction of the screw 9.

[0031] In one embodiment, the screw 9 is mounted on the output shaft of the motor 8. When the motor 8 is working, it can drive the screw 9 to rotate within the housing assembly 1. The screw 9 is connected to the heater assembly 4 via a transmission. When the screw 9 rotates under the drive of the motor 8, it can drive the heater assembly 4 to translate along the axial direction of the screw 9 (for example, the heater assembly 4 moves forward when the motor 8 rotates forward and moves backward when the motor 8 rotates in reverse). This allows the heater assembly 4 to have a first working position within the air duct 2 and a second working position outside the air duct 2 after the movement.

[0032] Driven by motor 8 and screw 9, the movement position of heater assembly 4 can be precisely controlled, resulting in more accurate positioning. Screw 9 is connected to heater assembly 4 via a transmission mechanism, and the screw 9 transmission has a reverse self-locking characteristic. After motor 8 stops working, heater assembly 4 can be stably maintained in the required working position without the need for an additional locking device, making the device safer to use.

[0033] Furthermore, such as Figure 4 and Figure 5 As shown, the heater assembly 4 includes: a bracket 10 and a heater 11 disposed on the bracket 10; the bracket 10 is provided with an internal thread portion 12, which is connected to the screw 9 in a driving connection.

[0034] In one embodiment, the heater 11 is mounted on the bracket 10, making the heater assembly 4 an independent movable module, which is convenient for assembly, maintenance or replacement. The bracket 10 is provided with an internal thread 12, and the bracket 10 is connected to the screw 9 through the internal thread 12. The rotational motion of the screw 9 is converted into the linear motion of the bracket 10 through the threaded transmission, thereby realizing the translational motion of the heater assembly 4 along the axial direction of the screw 9.

[0035] Furthermore, the linkage component 7 is a synchronizing rod, one end of which is movably connected to the bracket 10, and the other end of which is hinged to the wind deflector 6.

[0036] In one embodiment, the linkage component 7 can be a synchronizing rod, providing a low-cost and reliable rigid linkage solution; one end of the synchronizing rod is movably connected to the bracket 10, and the other end is hinged to the wind deflector 6. When the bracket 10 moves in the axial direction of the screw 9, the synchronizing rod can convert the linear motion of the bracket 10 into the rotation of the wind deflector 6, thereby ensuring that the opening and closing action of the wind deflector 6 is smooth.

[0037] Furthermore, the bracket 10 is provided with a convex shaft 13, and the synchronizing rod is provided with an oblong hole 14 that slides in accordance with the convex shaft 13.

[0038] In one embodiment, the bracket 10 is provided with a convex shaft 13 and the synchronizing rod is provided with an oblong hole 14. The convex shaft 13 and the oblong hole 14 are correspondingly slidably engaged to form a floating connection. This connection method allows for a certain degree of relative displacement freedom between the synchronizing rod and the bracket 10 during movement, which can compensate for manufacturing and assembly tolerances and prevent the mechanism from jamming during movement. At the same time, the floating connection method can ensure that the synchronizing rod can smoothly transfer the motion to the wind deflector 6, thereby improving the reliability and durability of the linkage system.

[0039] Furthermore, the housing assembly 1 includes: an outer shell 15 and a cover 16 mounted on the outer shell 15; the outer shell 15 is provided with a first guide groove 17 corresponding to the moving path of the heater assembly 4, and the internal thread portion 12 is movably disposed in the first guide groove 17; the air duct 2 and the air exchange port 3 are both disposed inside the outer shell 15.

[0040] In one embodiment, the housing assembly 1 consists of two parts: an outer shell 15 and a cover 16. The inner recess of the outer shell 15 forms a receiving cavity. The air duct 2 and the air exchange port 3 are both located in the receiving cavity of the outer shell 15. The cover 16 is installed on the outer shell 15 to close the receiving cavity, and at the same time plays a supporting and protective role, ensuring that the heater assembly 4 and other structures can be stably and safely installed in the housing assembly 1.

[0041] The first guide groove 17 is disposed in the receiving cavity of the outer shell 15, and the internal thread portion 12 is movably disposed in the first guide groove 17. The first guide groove 17 provides a precise linear motion trajectory for the internal thread portion 12, preventing the bracket 10 from deflecting or jamming when the screw 9 is driven, thereby ensuring the smooth movement of the heater assembly 4. In addition, the first guide groove 17 can also withstand the radial force when the internal thread portion 12 moves, thereby protecting the screw 9 thread connected to it and extending the service life of the transmission structure.

[0042] Furthermore, a raised rib 18 is provided on the side of the bracket 10 opposite to the internal thread portion 12, and a second guide groove 19 is provided on the cover 16 to slide in cooperation with the raised rib 18.

[0043] In one embodiment, the second guide groove 19 is disposed on the cover 16 and its position corresponds to the position of the first guide groove 17 on the outer shell 15. The bracket 10 is provided with a raised rib 18, which is located on the side opposite to the internal thread portion 12 on the bracket 10. The raised rib 18 and the second guide groove 19 are slidably engaged. The first guide groove 17 and the second guide groove 19 work together on both sides to guide the bracket 10. This guiding structure greatly enhances the stability of the movement of the bracket 10, making the heater assembly 4 move more smoothly in the housing assembly 1. In addition, the double-sided guiding method can also make the force on the bracket 10 more balanced, avoiding the imbalance or wear that may be caused by single-sided guiding.
