Description

Technical Field

[0001] This invention belongs to the technical field of household air conditioner heating equipment, and specifically relates to a household air conditioner heating equipment that prevents direct blowing and eliminates the feeling of wind. Background Technology

[0002] An air conditioner, or air conditioner, is used to regulate indoor air temperature. Air conditioners work by using a fan to increase airflow speed and exchange indoor and outdoor air to lower the temperature. In winter, they use air to blow over heating elements to raise the indoor air temperature. Traditional air conditioners rely on high-speed fans to force airflow, causing the airflow to blow directly onto people, which can easily lead to dryness, headaches, and other discomforts, especially for the elderly and children.

[0003] A search revealed that in the prior art, patent document CN215597459U, published on January 21, 2022, discloses an air conditioner cabinet unit and a heater, relating to the field of household appliance technology. The air conditioner cabinet unit includes a casing and a cross-flow fan installed within the casing. Multiple axial fan blades are fixedly mounted on the cross-flow fan, with each circle of axial fan blades arranged circumferentially and axially along the fan's axis. The air conditioner cabinet unit and heater provided by this invention add axial fan blades to the cross-flow fan. These multiple axial fan blades rotate with the cross-flow fan. Compared to traditional air conditioner cabinet units, the hot air that tends to rise during heating flows downwards under the action of the axial fan blades, thus preventing lower temperatures in the lower part of the cross-flow fan area and achieving temperature consistency across the air outlet, improving user comfort.

[0004] However, the device still has the following drawbacks: although it can achieve uniform temperature at the top and bottom of the air outlet, the air conditioner unit needs to rely on a high-speed fan to force airflow when heating the air, which causes the airflow to blow directly on the human body, easily causing discomfort such as dryness and headaches, and is especially unfriendly to the elderly and children. Summary of the Invention

[0012] Furthermore, the first layer plate has a hollow structure, and a first motor is installed inside the first layer plate. The output end of the first motor passes through the top of the first layer plate and is connected to the bottom of the rotating shaft for transmission.

[0013] Furthermore, a spiral heating plate is provided on the rotating shaft, and multiple sets of resistance heating wires are installed on the spiral heating plate.

[0014] Furthermore, the lifting mechanism is connected to the piston mechanism in a transmission manner. The lifting mechanism includes two sets of limiting shafts and two sets of threaded rods. The two sets of limiting shafts are fixedly connected between the first layer plate and the second layer plate, and the two sets of threaded rods are rotatably connected between the first layer plate and the second layer plate. A second motor is installed at the top of the outer wall of the first layer plate, and two sets of synchronous pulleys are rotatably connected inside the first layer plate.

[0019] The beneficial effects of this invention are:

[0020] 1. The air is heated by the intake heating mechanism. The heated air enters the outlet cylinder by moving the piston upward. The third motor drives the gear to rotate to a preset angle, causing several sets of strip baffles to rotate to a position where they are separated from and staggered with the overflow holes, thus no longer blocking the overflow holes. At this time, the piston moves downward, pushing the air in the outlet cylinder to overflow through several sets of overflow holes. The heat dissipation fins accelerate the heat dissipation. The double-layer cylinder wall overflow holes, piston mechanism and intermittent baffle mechanism work together to control the periodic opening and closing of the strip baffles to achieve pulsed air outlet, effectively achieving indoor air circulation heating while avoiding the discomfort of direct blowing.

[0021] 2. The first motor drives the rotating shaft to rotate, causing the first and second semicircular baffles to rotate synchronously. When the first and second semicircular baffles rotate to cover the fan-shaped air inlet and outlet respectively, a sealed space is formed inside the conical air guide hopper. The spiral heating plate fully heats the air inside the conical air guide hopper. The first motor drives the rotating shaft to continue rotating, causing the first and second semicircular baffles to rotate until they separate from the fan-shaped air inlet and outlet respectively. Indoor air enters through the fan-shaped air inlet, and the spiral heating plate drives the heated air to flow out through the fan-shaped outlet. Then, it enters the spiral telescopic tube through the guide tube and air guide pipe. This dynamic baffle design achieves air retention heating, reducing heat loss. The spiral heating plate adheres to the inner wall of the air guide hopper, forming turbulent heating, shortening the heating time, and thus effectively improving the efficiency of air heating.

[0022] 3. The indoor temperature is monitored by a temperature sensor. When the room temperature is low, the piston can be accelerated by adjusting the power of the resistance wire on the spiral heating plate and the speed of the first, second and third motors, so as to make the indoor temperature regulation more efficient. When the room temperature reaches the preset value, the heating speed can be reduced by reverse adjustment. The heating speed of this device can be flexibly adjusted to meet the indoor temperature heating needs of most families and effectively improve the universality of the device.

[0023] 4. As the piston moves up and down via the linkage block, the sliding ring moves up and down synchronously, causing the cleaning bristles to adhere to the outer surface of the air outlet and clean the overflow holes on the double-layer cylinder wall. This prevents dust from clogging the overflow holes and affecting airflow. When the cleaning bristles move to the bottom of the air outlet, the dust enters the dust box through the annular dust collection groove on the bottom plate for regular cleaning.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a household air conditioner heating device that prevents direct airflow and eliminates the feeling of draft, including a housing 100; for example, such as... Figure 1 and Figure 2 As shown.

[0037] The outer casing 100 has air outlet slots 110 on all four side walls, and a first dustproof net 120 can be detachably installed on each of the four air outlet slots 110. A top plate 200 is fixedly connected to the top of the outer casing 100. An air inlet slot 210 is provided at the center of the top plate 200. A second dustproof net 220 can be detachably installed on the air inlet slot 210. A bottom plate 300 is provided at the bottom of the outer casing 100. A dust box 310 is provided inside the bottom plate 300. An annular dust collection groove is provided on the bottom plate 300. The annular dust collection groove is connected to the inside of the dust box 310. A temperature sensor is also provided on the outer wall of the outer casing 100.

[0038] A first layer plate 400 is fixedly connected to the inside of the outer shell 100. A mounting bracket 500 is fixedly connected to the first layer plate 400. An air intake heating mechanism 600 is installed on the mounting bracket 500. A second layer plate 700 is fixedly connected to the inner wall of the outer shell 100. A limiting hole 710 is opened at the center of the second layer plate 700. A windless air outlet component 800 is embedded in the limiting hole 710. The windless air outlet component 800 includes a lifting mechanism 810, an air outlet cylinder 820, and a piston mechanism 830.

[0039] Specifically, indoor air enters the casing 100 through the air intake slot 210, and is heated by the air intake heating mechanism 600. The heated air is then processed by the windless air outlet component 800 and discharged through the air outlet 820. Finally, the hot air is discharged into the air through four sets of air outlet slots 110. Through the circulating heating operation of the indoor air, the indoor air can be regulated by heating.

[0040] For example, such as Figures 3-5 As shown.

[0041] The air intake heating mechanism 600 includes a conical air guide 610, which is fixedly mounted on a mounting bracket 500. An upper cover plate 620 is fixedly connected to the top of the conical air guide 610, and a fan-shaped air inlet 621 is provided on the upper cover plate 620. A lower cover plate 630 is fixedly connected to the bottom of the conical air guide 610, and a fan-shaped air outlet 631 is provided on the lower cover plate 630. A rotating shaft 640 is rotatably connected between the upper cover plate 620 and the lower cover plate 630. A spiral heating plate 650 is mounted on the rotating shaft 640. Multiple sets of resistance heating wires are installed on the hot plate 650. The spiral heating plate 650 is movably attached to the inner wall of the conical air guide 610. A first semi-circular baffle plate 660 and a second semi-circular baffle plate 670 are fixedly connected to the rotating shaft 640. The first semi-circular baffle plate 660 is fixedly connected to the top end of the spiral heating plate 650 and is movably attached to the bottom end of the upper cover plate 620. The second semi-circular baffle plate 670 is fixedly connected to the bottom end of the spiral heating plate 650 and is movably attached to the top end of the lower cover plate 630.

[0042] The bottom end of the lower cover plate 630 is provided with a flow guide cylinder 680, which is connected to the fan-shaped air outlet 631. The bottom end of the flow guide cylinder 680 is connected to an air guide pipe 681, which passes through the first layer plate 400 and is connected to a spiral telescopic pipe 682.

[0043] The first layer plate 400 has a hollow structure. A first motor 690 is installed inside the first layer plate 400. The output end of the first motor 690 passes through the top of the first layer plate 400 and is connected to the bottom of the rotating shaft 640 for transmission.

[0044] Specifically, the first motor 690 drives the rotating shaft 640 to rotate, causing the first semicircular baffle plate 660 and the second semicircular baffle plate 670 to rotate synchronously. When the first semicircular baffle plate 660 and the second semicircular baffle plate 670 rotate to cover the fan-shaped air inlet 621 and the fan-shaped air outlet 631 respectively, a sealed space is formed inside the conical air guide hopper 610. The spiral heating plate 650 fully heats the air inside the conical air guide hopper 610, effectively improving the efficiency of air heating.

[0045] Furthermore, the first motor 690 drives the rotating shaft 640 to continue rotating, causing the first semicircular baffle plate 660 and the second semicircular baffle plate 670 to rotate until they separate from the fan-shaped air inlet 621 and the fan-shaped air outlet 631, respectively. Indoor air enters through the fan-shaped air inlet 621, and the spiral heating plate 650 drives the heated air to flow out through the fan-shaped air outlet 631, thereby realizing the intermittent circulating heating operation of indoor air.

[0046] The lifting mechanism 810 includes two sets of limiting shafts 811 and two sets of threaded rods 812. The two sets of limiting shafts 811 are fixedly connected between the first layer plate 400 and the second layer plate 700. The two sets of threaded rods 812 are rotatably connected between the first layer plate 400 and the second layer plate 700. A second motor 813 is installed at the top of the outer wall of the first layer plate 400. Two sets of synchronous pulleys 814 are rotatably connected inside the first layer plate 400. Synchronous belts 815 are sleeved on the two sets of synchronous pulleys 814. The center of one set of synchronous pulleys 814 is connected to the output end of the second motor 813. The bottom center of the two sets of synchronous pulleys 814 is fixedly connected to one end of the two sets of threaded rods 812 respectively.

[0047] For example, such as Figures 6-9 As shown.

[0048] The piston mechanism 830 includes a linkage block 831. Four sets of crossbars 832 are fixedly connected to the side wall of the linkage block 831. The other end of each of the four sets of crossbars 832 is fixedly connected to a movable ring 833. Two sets of movable rings 833 are threadedly connected to two sets of threaded rods 812, and the other two sets of movable rings 833 are movably fitted to two sets of limiting shafts 811. A piston rod 834 is fixedly connected to the bottom end of the linkage block 831. A piston 835 is fixedly connected to the bottom end of the piston rod 834. The piston 835 is movably fitted to the inner wall of the air outlet cylinder 820.

[0049] Both the linkage block 831 and the piston rod 834 are hollow structures. The linkage block 831 and the piston rod 834 are internally connected. The bottom end of the piston rod 834 passes through the piston 835 and extends into the air outlet 820. A connecting pipe 836 is provided on the linkage block 831. The connecting pipe 836 is internally connected to the spiral telescopic pipe 682.

[0050] The air outlet 820 includes a double-layer cylinder wall 821, and several sets of overflow holes 822 are provided on the double-layer cylinder wall 821. The overflow holes 822 on the double-layer cylinder wall 821 correspond one to one. The bottom of the double-layer cylinder wall 821 is fixedly connected to the cylinder bottom 823. The outer wall of the air outlet 820 is fitted with a heat dissipation fin plate 860.

[0051] Specifically, the second motor 813 drives a set of synchronous pulleys 814 to rotate, which in turn drives two sets of threaded rods 812 to rotate synchronously. This causes the linkage block 831 to drive the piston 835 to move up and down. When the piston 835 moves upward, the heated air enters the connecting pipe 836 through the spiral telescopic tube 682, and then passes through the linkage block 831 and the piston rod 834 before finally entering the air outlet 820. When the piston 835 moves downward, it pushes the air in the air outlet 820 to scatter and overflow through several sets of overflow holes 822, and accelerates the heat dissipation through the heat dissipation fins 860.

[0052] The bottom ends of the four sets of horizontal bars 832 are all fixedly connected to vertical bars 840, and the bottom ends of the four sets of vertical bars 840 are fixedly connected to cleaning parts 850. The cleaning parts 850 include a sliding ring 851, a sliding groove 852 is provided on the sliding ring 851, the sliding groove 852 is movably fitted with the outer wall of the air outlet 820, and an annular mounting groove 853 is provided on the sliding ring 851. The inner wall of the annular mounting groove 853 is provided with cleaning bristles 854, and one end of the cleaning bristles 854 is movably fitted with the outer wall of the air outlet 820.

[0053] Specifically, while the piston 835 moves up and down via the linkage block 831, the sliding ring 851 moves up and down synchronously, causing the cleaning bristles 854 to adhere to the outer surface of the air outlet 820 and clean the overflow holes 822 opened on the double-layer cylinder wall 821. This prevents dust from clogging the overflow holes 822 and affecting the air overflow. When the cleaning bristles 854 move to the bottom of the air outlet 820, the dust enters the dust box 310 through the annular dust collection groove opened on the bottom plate 300 for collection, so as to be cleaned regularly.

[0054] An intermittent blocking mechanism 870 is provided inside the double-layer cylindrical wall 821. The intermittent blocking mechanism 870 includes a top connecting ring 871 and a bottom connecting ring 872. The bottom connecting ring 872 is rotatably connected to the bottom of the cylinder 823. Several sets of strip-shaped blocking plates 873 are fixedly connected between the top connecting ring 871 and the bottom connecting ring 872. The several sets of strip-shaped blocking plates 873 are movably fitted inside the double-layer cylindrical wall 821. An arc-shaped toothed plate 874 is laid at the top of the top connecting ring 871. A motor frame 875 is provided on the second layer plate 700. A third motor 876 is installed on the motor frame 875. A gear 877 is drivenly connected to the output end of the third motor 876. The gear 877 meshes with the arc-shaped toothed plate 874.

[0055] Specifically, the third motor 876 drives the gear 877 to rotate to a preset angle, causing the arc-shaped toothed plate 874 to rotate synchronously. This causes the top connecting ring 871 to drive several sets of strip-shaped baffles 873 to rotate synchronously, blocking the overflow hole 822 and creating a sealed space between the air outlet 820 and the piston 835. At this time, the piston 835 moves upward, and the heated air enters the air outlet 820 through the bottom end of the piston rod 834. When the piston 835 moves upward to its maximum displacement, the third motor 876 drives the gear 877 to continue rotating to a preset angle, causing the strip-shaped baffles 873 to rotate to a position where they are separated from and intersected with the overflow hole 822, thus no longer blocking the overflow hole 822. At this time, the piston 835 moves downward again, expelling the hot air from the air outlet 820. This achieves the process of hot air circulating into and out of the air outlet 820, and effectively avoids interference from indoor air on the gas circulation inside the air outlet 820 during the hot air circulation process.

[0056] The working principle of the household air conditioning heating device with anti-direct-blowing and windless function proposed in this invention is as follows:

[0057] Indoor air enters the casing 100 through the air inlet slot 210, and is heated by the air intake heating mechanism 600. The heated air is then processed by the windless air outlet component 800 and discharged through the air outlet pipe 820. Finally, the hot air is discharged into the air through four sets of air outlet slots 110. Through the circulating heating operation of indoor air, the heating regulation of indoor air is achieved.

[0058] The first motor 690 drives the rotating shaft 640 to rotate, causing the first semicircular baffle plate 660 and the second semicircular baffle plate 670 to rotate synchronously. When the first semicircular baffle plate 660 and the second semicircular baffle plate 670 rotate to cover the fan-shaped air inlet 621 and the fan-shaped air outlet 631 respectively, a sealed space is formed inside the conical air guide hopper 610. The spiral heating plate 650 fully heats the air inside the conical air guide hopper 610. By intermittently sealing the heating space, the air is retained and heated, thereby effectively improving the efficiency of air heating.

[0059] The first motor 690 drives the rotating shaft 640 to continue rotating, causing the first semicircular baffle plate 660 and the second semicircular baffle plate 670 to rotate until they are separated from the fan-shaped air inlet 621 and the fan-shaped air outlet 631, respectively. Indoor air enters through the fan-shaped air inlet 621, and the spiral heating plate 650 drives the heated air to flow out through the fan-shaped air outlet 631, and then enters the spiral telescopic tube 682 through the guide tube 680 and the air guide pipe 681.

[0060] At the same time, the third motor 876 drives the gear 877 to rotate to a preset angle, causing the arc-shaped toothed plate 874 to rotate synchronously. This causes the top connecting ring 871 to drive several sets of strip-shaped baffles 873 to rotate synchronously, blocking the overflow hole 822 and creating a sealed space between the air outlet 820 and the piston 835. The second motor 813 drives a set of synchronous pulleys 814 to rotate, causing the two sets of synchronous pulleys 814 to drive the two sets of threaded rods 812 to rotate synchronously. This causes the linkage block 831 to drive the piston 835 to move upward, allowing the heated air to enter the connecting pipe 836 through the spiral telescopic tube 682, and then through the linkage block 831 and the piston rod 834, finally entering the air outlet 820.

[0061] When the piston 835 moves upward to its maximum displacement, the third motor 876 drives the gear 877 to continue rotating to a preset angle, causing several sets of strip-shaped baffles 873 to rotate to a position where they are separated from and intersected with the overflow holes 822, thus no longer blocking the overflow holes 822. At this time, the piston 835 moves downward again, pushing the air in the air outlet 820 to scatter and overflow through several sets of overflow holes 822. The heat is discharged faster through the heat dissipation fins 860. At the same time, the first motor 690 drives the rotating shaft 640 to rotate, causing the first semicircular baffle 660 and the second semicircular baffle 670 to rotate synchronously to cover the fan-shaped air inlet 621 and the fan-shaped air outlet 631 respectively, and to perform the closed heating operation of the trapped air again.

[0062] As the piston 835 moves up and down driven by the linkage block 831, the sliding ring 851 moves up and down synchronously, so that the cleaning bristles 854 are in contact with the outer surface of the air outlet 820 to clean the overflow hole 822 opened on the double-layer cylinder wall 821, so as to prevent dust from clogging the overflow hole 822 and affecting the air overflow. When the cleaning bristles 854 move to the bottom of the air outlet 820, the dust enters the dust box 310 through the annular dust collection groove opened on the bottom plate 300 for collection, so as to perform regular cleaning.

[0063] Although the present invention 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; and these 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 the present invention.
