Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 7, the low-energy-consumption silent and comfortable all-in-one machine for warm air and ventilation comprises a machine body 1 and a controller 2 installed on the machine body 1, wherein the controller 2 is connected with an external control panel 11 through an electric wire. The body 1 includes a panel 11 and a cover plate 12 connected to the panel 11 by screws. The panel 11 or the cover plate 12 is provided with a mounting opening 3 for mounting an electric device, and in order to increase the waterproof sealing performance of the electric device, a waterproof sealing ring 24 is arranged in the mounting opening 3 or the electric device is sealed by glue pouring. The controller 2 is connected with each power component through electric wires to control the work of the power components.

Two air ducts are arranged in the machine body 1, and each air duct comprises an air inlet 4 and an air outlet 5. Each air inlet 4 is covered with a fan housing 6, and the fan housing 6 is fixed on the panel 11 through screws. A motor 8 with a wind wheel 7 is correspondingly arranged in each fan cover 6. The wind wheel 7 is provided with a connecting part 29 which is rotationally connected with the motor 8, the connecting part 29 is provided with a connecting hole, and a hard cushion block 30 is arranged in the connecting hole. The wind cover 6 is combined with the wind wheel 7, and a wind cavity 9 is formed inside the wind cover. Referring to fig. 4, the size of the wind cavity 9 gradually decreases along the direction of the forward rotation of the wind wheel 7. The motor 8 drives the wind wheel 7 to rotate, and air is sucked into the wind cavity 9. The motor 8 is controlled by the controller 2.

Referring to fig. 2, the air outlet 5 of one of the air ducts includes a ventilation outlet 10 and a heating outlet 13. The air duct is used for warm air and ventilation. The wind wheel air outlet 25 of the wind cover 6 on the wind channel is connected with a wind channel switching cover 14 communicated with the ventilation outlet 10 and the warm air outlet 13. A connecting strip 27 is arranged at the wind wheel air outlet 25, and a connecting groove 28 clamped with the connecting strip 27 is arranged at the end part of the air duct switching cover 14; the air duct switching cover 14 is connected with the fan cover 6 in a clamping mode, the sealing performance is good, and air leakage of the air duct is avoided.

Referring to fig. 3, a PTC heater 15 and an air deflector 16 installed in the air duct switching cover 14 are sequentially disposed on the air duct and along the air outlet direction of the wind wheel 7. A catching groove 18 is formed in the duct switching cover 14, and the PTC heater 15 is mounted in the catching groove 18. A micro motor 17 is installed on the outer side of the air duct switching cover 14, and the micro motor 17 is connected with the air deflector 16 and can drive the air deflector 16 to rotate so as to switch and communicate the ventilation outlet 10 or the heating outlet 13. An opening 26 communicated with the ventilation outlet 10 is formed on the outer end surface of the air channel switching cover 14, and the air outlet cover 19 is connected to the opening 26. The micro motor 17 is controlled by the controller 2. Referring to fig. 6, three flow stabilizing plates 29 are uniformly arranged on the air deflector 16 at equal intervals, and air flows out of the air cavity 9 and is concentrated to flow to one side under the action of centrifugal force, so that the air flows out unevenly; the three flow stabilizing plates 29 can stabilize the flow and make the air flow out uniformly.

The air outlet 5 of the other air duct is a ventilation outlet 10, and the air duct is used for ventilation. An air outlet cover 19 communicated with the ventilation outlet 10 is connected to the wind wheel air outlet 25 of the wind cover 6 on the air duct.

Referring to fig. 5, in order to block a portion of air from escaping from the air chamber 9 at the air inlet 4 of each air duct, a pressure air ring 20 is installed on a surface of the machine body 1 opposite to the air cover 6. The press damper 20 is integrally formed with the face plate 11. The air pressing ring 20 comprises an air pressing ring plate body 21 and an air pressing ring body 22 which is integrally arranged with the air pressing ring plate body 21 and extends towards the axial center direction of the air inlet 4 along the circumferential direction of the air inlet 4; the wind pressing ring body 22 is inwards concave towards the wind wheel 7.

The wind wheel rotates to drive air to enter the air channel from the air inlet so as to form air flow; as the wind wheel rotates, a part of air can flow out from the air inlet and collide with the air sucked into the air inlet from bottom to top, so that the air flow is disordered; meanwhile, force acts on the wind wheel to bring load to the wind wheel, so that the electric energy consumption of the motor is increased; in addition, forces act on the rotor, which may be unbalanced when rotating, thereby causing vibrations and noise. The air pressing ring can prevent a part of air from jumping out from the inside, solves the problem of disordered flow of the air, reduces the electric energy consumption of the motor, and achieves the effects of silence and environmental protection.

The width of the wind pressing ring body 22 is gradually increased along the positive rotation direction of the wind wheel 7; the ratio of the minimum width of the wind pressing ring body 22 to the maximum width of the wind pressing ring body 22 is 1: 2-2.5. The optimal ratio is 1: 2.2. If the design of the air pressing ring body is too large, the wind wheel can not suck enough air quantity when rotating, so that the working efficiency of the machine is low; if the design of the air pressing ring body is too small, the blocking effect of the air pressing ring is not good, and air can escape from the inside to cause air convection; therefore, through comparison of multiple tests, when the ratio of the minimum width value of the wind pressing ring body to the maximum width value of the wind pressing ring body is 1:2-2.5, the wind pressing ring achieves the optimal effect.

In addition, referring to fig. 7, the wind wheel 7 is provided with a plurality of blades, and one of the blades is provided with a dynamic balance weight 23. The dynamic balance block 23 plays a role in adjusting when the wind wheel 7 rotates, so that the wind wheel 7 is stressed uniformly and does not shake.

The working principle is as follows: the intelligent controller 2 is started, the motor 8 drives the wind wheel 7 to rotate, air is sucked into the air cavity 9 from the air inlet 4 and then flows out of the air cavity 9 to pass through the PTC heater 15, the PTC heater 15 is started to heat the air to form warm air, the warm air enters the air channel switching cover 14, the micro motor 17 controls the air deflector 16 to switch the air channel to be communicated with the warm air outlet 13, and the warm air is guided by the air deflector 16 to flow out of the warm air outlet 13; in addition, the PTC heater 15 does not heat, the micro motor 17 controls the air deflector 16 to switch the air channel to be communicated with the ventilation outlet 10, and air is discharged from the ventilation outlet 10; in addition, another motor 8 drives the wind wheel 7 to rotate, and ventilation can be carried out simultaneously.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
