Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] In the conventional design of air conditioner indoor units, a motor drives a fan to generate forced airflow. This airflow passes through a heat exchanger to achieve heat exchange, thereby regulating the indoor temperature. However, in existing technologies, the airflow generated by the fan during operation often suffers from flow losses. This portion of the airflow fails to effectively participate in the heat exchange process, resulting in some wind energy being underutilized and converted into ineffective work, causing energy waste and reducing overall energy efficiency.

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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.

[0026] The following is combined with Figure 1 and Figure 2 This invention describes an indoor air conditioning unit and an air conditioner according to an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0027] An embodiment of the first aspect of this utility model provides an indoor unit for an air conditioner, such as... Figure 1 and Figure 2 As shown, it includes: a wind duct 100; a working fan 200, which is disposed within the wind duct 100; and a wind power generation component 300, which is disposed within the wind duct 100. The wind duct 100 can divert part of the wind to the wind power generation component 300 so that the wind power generation component 300 can generate wind power.

[0028] The indoor unit of the air conditioner provided by this utility model includes an air duct 100, a working fan 200, and a wind power generation component 300. The working fan 200 is disposed within the air duct 100. During operation, the working fan 200 rotates to generate forced airflow, which flows through a heat exchanger to achieve heat exchange, thereby regulating the indoor temperature. The wind power generation component 300 is also disposed within the air duct 100. During normal operation of the working fan 200, the air duct 100 can divert some airflow to the wind power generation component 300, enabling the wind power generation component 300 to generate wind power.

[0029] As described above, by integrating a wind power generation component 300 into the air duct 100 of the indoor unit of the air conditioner, and effectively guiding some of the airflow generated by the operating fan 200—which would otherwise form ineffective circulation, eddies, or turbulence at the blade tips or volute gaps—to the wind power generation component 300, the capture and conversion of such ineffective wind energy is achieved. This design directly converts the previously wasted airflow energy into electrical energy, significantly reducing energy loss caused by ineffective airflow and improving the overall energy efficiency of the air conditioner.

[0030] In one embodiment of the present invention, the indoor unit of the air conditioner further includes an energy storage device 400, which is connected to the wind power generation component 300 and is used to store the electrical energy generated by the wind power generation component 300.

[0031] This technical solution integrates a wind power generation component 300 into the indoor unit of an air conditioner, supplemented by an energy storage device 400, to achieve efficient capture, conversion, and utilization of ineffective wind energy generated during the operation of the working fan 200. The wind power generation component 300 converts the captured ineffective wind energy into electrical energy, and the energy storage device 400 stores this unstable regenerated electrical energy in real time. This solves the problem of unstable output power caused by airflow fluctuations in wind power generation, ensuring that all recovered energy is effectively stored and avoiding secondary waste caused by instantaneous power generation exceeding load demand or grid connection limitations.

[0032] In one embodiment of this utility model, the indoor unit of the air conditioner further includes a power supply module connected to an energy storage device 400. The power supply module includes, but is not limited to, a power supply structure for internal loads such as the indoor unit controller, sensors, display panel, and stepper motors (e.g., air guide plate drivers); the stored energy can be flexibly allocated over time according to system needs. For example, when the air conditioner is operating under high load or when the external power grid is insufficient, the stored energy is preferentially used to drive internal loads such as the indoor unit controller, sensors, display panel, and stepper motors (e.g., air guide plate drivers); when the air conditioner is in standby or low-power operation, the stored energy can continuously power the standby circuit, significantly reducing standby power consumption. This achieves optimized matching of recovered energy and load demand over time.

[0033] In addition, the stored electrical energy can serve as an emergency backup power source, maintaining the short-term operation of critical control circuits when the main power supply of the air conditioner fails.

[0034] In one embodiment of the present invention, the wind power generation component 300 includes: a generator fan 310, which is disposed in a wind duct 100, and the wind duct 100 is capable of directing wind to the generator fan 310; and a generator connected to the generator fan 310.

[0035] Furthermore, in one embodiment of this utility model, the wind power generation component 300 further includes: a rectifier connected to a generator; and a voltage regulator connected to the rectifier.

[0036] In one embodiment of the present invention, the energy storage device 400 includes an energy storage battery connected to a voltage regulator.

[0037] When the working fan 200 of the indoor unit of the air conditioner is running, the air duct 100 directs the originally wasted ineffective wind energy (such as the vortex at the blade tip and the turbulence in the volute gap) in the main airflow to the generator fan 310, driving the generator fan 310 to rotate. The generator fan 310 drives the generator rotor to rotate through the mechanical transmission shaft, converting the captured wind energy into AC power. After the AC power is converted into DC power by the rectifier, it is then processed by the voltage regulator to suppress voltage amplitude and fluctuations, forming a stable DC output. Finally, the regulated DC power is sent to the energy storage battery for storage, completing the complete conversion and storage process from waste wind energy to dispatchable electrical energy.

[0038] Through the coordinated design of the refined wind power generation component 300 and the energy storage device 400, three core effects are achieved: efficient capture and stable conversion: the directional diversion of the generator fan 310 and the wind duct 100 accurately recovers ineffective wind energy, and the rectification-voltage regulation dual-stage circuit completely solves the problem of voltage instability caused by airflow fluctuations, ensuring energy conversion efficiency; safe storage and flexible power supply: the energy storage battery, as a stable container, not only avoids the impact risk of unstable power on the load, but also realizes the cross-time allocation of stored power, which can seamlessly support the continuous power supply of internal loads such as air conditioning controllers and sensors; deep energy saving and system value-added: the recovered power can assist in reducing grid consumption, significantly improving the overall energy efficiency, while the energy storage battery also has the function of emergency backup power, enhancing system robustness and forming a self-consistent energy closed loop of "recovery-storage-utilization".

[0039] In one embodiment of the present invention, the energy storage device 400 further includes a battery protection board, which is connected between the voltage regulator and the energy storage battery.

[0040] The battery protection board can monitor the voltage, current and temperature parameters of the energy storage battery in real time, and actively implement overcharge / over-discharge / short circuit / overcurrent protection to effectively avoid the risk of battery thermal runaway caused by wind energy fluctuations.

[0041] In one embodiment of the present invention, the working fan 200 includes a centrifugal fan disposed within the air duct 100.

[0042] In another embodiment of this utility model, the generator fan 310 includes an axial flow fan disposed within an air duct 100, which directs a portion of the airflow to the axial flow fan. This portion of the airflow includes ineffective wind energy generated during operation, such as eddies at the blade tips and turbulence in the volute gap.

[0043] A second aspect of this utility model provides an air conditioner, including the indoor unit described above.

[0044] Furthermore, the air conditioner provided by this utility model, since it includes the indoor unit as described above, also possesses the advantages described above.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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. Such 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 this utility model.
