Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1, fig. 1 is a structural frame diagram of an air conditioner according to an embodiment of the present invention. The present invention provides an air conditioner, which generally comprises an indoor unit 20 installed indoors and an outdoor unit 10 installed outdoors, wherein the indoor unit 20 and the outdoor unit 10 can be connected through a refrigerant pipeline to realize the refrigeration and heating circulation of the air conditioner, thereby realizing the cold and heat regulation of the indoor temperature.

The refrigeration system of the air conditioner can be realized by using a compression refrigeration cycle, and the compression refrigeration cycle realizes heat transfer by using a compression phase change cycle of a refrigerant in a compressor 113, a condenser, an evaporator and a throttling device 114. The refrigeration system may further include a refrigerant flow direction switching device 115 to change the flow direction of the refrigerant, so that the indoor heat exchanger 202 is alternatively used as an evaporator or a condenser, and correspondingly, the outdoor heat exchanger 112 is alternatively used as a condenser or an evaporator to achieve the cooling or heating function, and the refrigerant flow direction switching device 115 is generally implemented by a four-way valve.

In addition, the indoor unit 20 may further include an indoor unit fan 204, the outdoor unit 10 may further include an outdoor unit fan 110, and the indoor unit fan 204 and the outdoor unit fan 110 may generate air flows for heat exchange with the indoor unit heat exchanger 202 and the outdoor unit heat exchanger 112, respectively, to promote the heat exchange.

Referring to fig. 2, fig. 2 is a schematic structural view of an outer casing 100, an outdoor unit fan 110, an exciting unit 120, and a winding coil 130 in an air conditioning apparatus according to an embodiment of the present invention. In some embodiments, the air conditioner may further include an exciting device 120 fixed to the outdoor unit fan 110 and configured to generate a rotating magnetic field when the outdoor unit fan 110 rotates, and a winding coil 130 disposed on the outer casing 100 and opposite to the exciting device 120 and configured to cut the rotating magnetic field when the outdoor unit fan 110 rotates to generate an alternating current.

Since the outdoor fan 110 is used to radiate heat from the outdoor heat exchanger 112, and the distance between the outdoor fan 110 and the front wall of the external casing 100 is not large in order to discharge the radiated airflow as quickly as possible, the exciting device 120 may be disposed on a surface of the outdoor fan 110 close to the front wall of the external casing 100, and the winding coil 130 may be directly fixed on the front wall of the external casing 100, so that when the exciting device 120 rotates with the outdoor fan 110, the winding coil 130 may be in the rotating magnetic field generated by the exciting device 120 and generate a relative motion with the rotating magnetic field, cutting the rotating magnetic field, so as to generate an alternating current.

As described in the background section, in order to fully utilize resources, a power generation device that drives a wind power generation device by using air flow discharged from a heat exchange fan has been developed in the prior art, but the wind power discharged from the heat exchange fan is weak, and the conversion rate of the wind power is low, so that the wind power cannot be converted into effective electric power.

In the air conditioner of the present embodiment, the outdoor fan 110 directly drives the excitation device 120 to generate a rotating magnetic field, and the winding coil 130 cuts the rotating magnetic field, thereby generating electric energy. The wind energy generated by the heat exchange fan is used for generating electricity, firstly, the kinetic energy of the heat exchange fan is converted into the wind energy, then the wind energy is converted into the kinetic energy, and finally the converted kinetic energy is used for driving the wind driven generator to rotate so as to generate the electric energy. As can be seen from the comparison, compared with the wind power generation device for generating power, the air conditioning device of the present embodiment has higher power generation efficiency, and can generate relatively stable power without being affected by external conditions as long as the outdoor unit fan 110 operates.

In some embodiments, the excitation device 120 may be an electromagnet, an iron core of the electromagnet may be fixed to the outdoor unit fan 110, a coil of the electromagnet is energized to generate a magnetic field, and the electromagnet generates a rotating magnetic field when rotating with the outdoor unit fan 110.

Referring to fig. 2, in some embodiments, the excitation device 120 may further include two permanent magnets, the two permanent magnets are respectively fixed to two opposite blades of the outdoor unit fan 110, and opposite magnetic poles of the two permanent magnets are arranged opposite to each other, that is, an N pole of one permanent magnet is opposite to an S pole of the other permanent magnet.

The two permanent magnets may be elongated and extend along the length of the blades of the outdoor unit fan 110, and the two permanent magnets may fix the two blades of the outdoor unit fan 110 opposite to each other, so that a magnetic field may be generated between the two permanent magnets.

Further, the two permanent magnets may be Rubber magnets (Rubber magnets), which are one of ferrite magnetic material series, and are made by compounding bonded ferrite magnetic powder with synthetic Rubber and performing extrusion molding, calendering molding, injection molding and other processes, and have flexibility, elasticity and twistability. When assembling, the permanent magnet may be formed in a corresponding shape according to the shape of the blades of the outdoor unit fan 110, so that the permanent magnet and the blades are fixed.

In addition, since the rubber magnet is formed by compounding bonded ferrite magnetic powder and synthetic rubber, the rubber magnet has a lower density, which is closer to the density of plastic, compared to the conventional oxidized magnet, and thus, when the permanent magnet is mounted to the blades of the outdoor unit fan 110, the outdoor unit fan 110 is less affected by the permanent magnet.

In some specific embodiments, the blades of the outdoor unit fan 110 may further have mounting grooves, and the permanent magnet is fixed in the mounting grooves, so that the permanent magnet is conveniently fixed, and the permanent magnet may be used to fill the space of the mounting grooves, thereby reducing the influence on the outdoor unit fan 110.

Referring to fig. 2, in some embodiments, the number of the winding coils 130 may be two, and the two winding coils 130 are symmetrically distributed on the inner side of the front wall of the outer casing 100 around the rotation axis of the outdoor unit fan 110.

In the present embodiment, since the number of the winding coils 130 is two, and the two winding coils 130 are symmetrically disposed, after the excitation device 120 rotates, the two winding coils 130 can respectively generate sine wave ac electromotive forces, that is, the power generation system of the present embodiment can generate two-phase ac power to supply power to the power consumption unit of the air conditioner.

Referring to fig. 3, fig. 3 is a functional block diagram of an air conditioner according to an embodiment of the present invention. In some embodiments, the air conditioner may further include a rectifier 140 and an energy storage device 150, the rectifier 140 is connected to the winding coil 130 to convert the ac power output from the winding coil 130 into dc power, and the energy storage device 150 may be a storage battery connected to the rectifier 140 to store the dc power converted by the rectifier 140.

Rectifier 140 is a device that converts alternating current to direct current and has two main functions: firstly, Alternating Current (AC) is changed into Direct Current (DC), and the DC is supplied to a load after being filtered or is supplied to an inverter; second, a charging voltage is supplied to the secondary battery.

On one hand, since the air conditioner has a large number of dc power consuming units, such as some sensors, etc., the rectifier 140 may convert the ac power outputted from the winding coil 130 into dc power for supplying to the dc power consuming units; on the other hand, the electric energy output by the winding coil 130 can also be stored in the energy storage device 150, that is, the energy storage device 150 is charged, so as to supply power to the electricity utilization unit when electricity is needed, and since the energy storage device 150 needs to convert the alternating current into the direct current during the charging process and then charges, the rectifier 140 can also function as a charger.

Referring to fig. 3, in some embodiments, the air conditioner may further include an electric heating device 160, and the electric heating device 160 may be installed in the outdoor heat exchanger 112, the indoor heat exchanger 202, or both the outdoor heat exchanger 112 and the indoor heat exchanger 202.

In general, during the use of the air conditioner, the outdoor heat exchanger 112 is used as an evaporator in the heating mode, and the indoor heat exchanger 202 is used as an evaporator in the cooling mode, so that the temperature of the refrigerant flowing in the evaporator is low, which may cause frosting. In order to achieve defrosting, a four-way valve is conventionally arranged on a refrigerant pipeline to switch the flow direction of the refrigerant, for example, in a cooling mode, the indoor unit heat exchanger 202 is used as an evaporator, frosting may occur on the indoor unit heat exchanger 202 at this time, the four-way valve is switched to reverse the flow direction of the refrigerant (i.e., to switch to a heating mode), and at this time, the indoor unit heat exchanger 202 is used as a condenser, and a high-temperature and high-pressure refrigerant flows through the indoor unit heat exchanger to achieve defrosting. However, this method requires switching of the cooling or heating mode of the air conditioner, and the process is complicated.

In this embodiment, the air conditioner can directly utilize the electric heating device 160 to defrost the outdoor heat exchanger 112 and/or the indoor heat exchanger 202. Electrical heating device 160 may be electrically connected to energy storage device 150 such that energy storage device 150 powers temperature sensor 170.

Taking the outdoor heat exchanger 112 as an example, a sensor may be disposed on the outdoor heat exchanger 112 for frost formation detection (e.g., a temperature sensor, a weight sensor, etc.), when it is detected that the outdoor heat exchanger 112 meets a defrosting condition, the energy storage device 150 may supply power to the electric heating device 160, and the electric heating device 160 generates heat to act on the outdoor heat exchanger 112, so as to achieve defrosting.

In addition, since the electric energy of the energy storage device 150 is derived from the kinetic energy of the outdoor unit fan 110, the electric heating device 160 does not need to consume additional electric energy, so that the kinetic energy of the outdoor unit fan 110 can be fully utilized, and not only defrosting but also energy saving can be realized.

In addition, in order to facilitate the utilization of the electric energy generated by the winding coil 130, the energy storage device 150 may be directly disposed in the outer casing 100, so that the distance of the energy storage device 150 supplying the electric heating device 160 installed in the outdoor unit heat exchanger 112 is shortened, and the power supply line is simplified.

Referring to fig. 3, in some embodiments, the air conditioner may further include a plurality of temperature sensors 170, the number of the temperature sensors 170 may be multiple, and a plurality of temperature sensors 170 may be disposed at a location where the air conditioner needs to collect temperature information, and the temperature sensors 170 are electrically connected to the energy storage device 150, so that the energy storage device 150 supplies power to the temperature sensors 170.

Specifically, the temperature sensor 170 may also be a wireless temperature sensor 170, and the wireless temperature sensor 170 has a function of wirelessly transmitting signals compared to a conventional sensor, and has a wireless transmission module therein (e.g., a Wi-Fi module, a 433m wireless module, a Zigbee module, etc.), and a wireless receiving module is correspondingly arranged at a signal receiving side of the temperature sensor 170, so as to simplify a circuit.

The air conditioner has a small space, the temperature sensors 170 in narrow positions are difficult to install (such as the coil pipes of the outdoor unit heat exchanger 112), and the traditional sensors need complicated wiring to realize power supply and signal transmission, so that the assembly and maintenance difficulty is increased.

In this embodiment, the energy storage device 150 may provide power for the temperature sensor 170, the temperature sensor 170 is a wireless temperature sensor 170, and the energy storage device 150 may be disposed in the outer casing 100, so that the energy storage device 150 may directly supply power to the temperature sensor 170, and the cost and the process are saved.

Referring to fig. 4, fig. 4 is a schematic view of an indoor unit 20 of an air conditioning device according to an embodiment of the present invention. In some embodiments, the indoor unit 20 further includes an inner casing 200 and a storage box 210, the storage box 210 has a storage space for storing a remote controller 230, and the storage box 210 is connected to a lower portion of the inner casing 200 by a connecting member 220 and is configured to be movable between a storage position retracted into the inner casing 200 and a pick-and-place position separated from the inner casing 200.

The connection member 220 may be a rope, a contraction rod, etc., and in order to ensure the balance of the process of the storage box 210, the rope may be multiple to connect the storage box 210 to the lower side of the inner case 200, and the connection member 220 may be lifted and lowered between the storage position and the pick-and-place position by a motor. When the storage box 210 is in the pick-and-place position, the user can place the remote controller 230 in the storage space of the storage box 210, and when the storage box 210 is in the storage position, the storage box 210 can be lifted and retracted into the inner casing 200 of the indoor unit 20 to perform a storage function, and dust or bacterial pollution can be avoided.

In some embodiments, the indoor unit 20 may be a wall-mounted indoor unit, and a gravity sensor may be further disposed at the bottom of the storage box 210, so that when the remote controller 230 is placed in the storage box 210, the motor may be automatically controlled to start to drive the storage box 210 to ascend to the storage position. The inner casing 200 of the indoor unit 20 may further be provided with a human body sensing device (e.g., an infrared sensor), and when it is detected that the user is located below the indoor unit 20, the motor may be automatically controlled to start, so as to drive the storage box 210 to descend to the pick-and-place position, thereby facilitating the user to take off the remote controller 230.

Referring to fig. 3 and 4, in some embodiments, the bottom of the storage box 210 may further be provided with a power supply transmitting module 212 connected to the energy storage device 150, the remote controller 230 has a power supply receiving module 232, and when the remote controller 230 is located in the storage space, the power supply transmitting module 212 and the power supply receiving module 232 are close to each other and electrically conducted, so that the energy storage device 150 charges the remote controller 230.

The traditional remote controller uses a dry battery or a rechargeable battery for power supply, but the dry battery is frequently replaced, the cost is high, and the waste battery can pollute the environment. In order to solve these problems, the energy storage device 150 of the remote controller 230 of the present embodiment charges the remote controller 230, so as to fully utilize energy, save cost and improve environment.

In the air conditioner of the present invention, the exciting unit 120 is fixed to the outdoor unit fan 110 to generate a rotating magnetic field as the outdoor unit fan 110 rotates, and the winding coil 130 is fixed to the outer casing 100 and opposite to the exciting unit 120 and configured to cut the rotating magnetic field when the outdoor unit fan 110 rotates to generate ac power, which has higher power generation efficiency than a wind power generating unit, and can generate relatively stable electric power as long as the outdoor unit fan 110 operates, with less influence of external conditions.

Further, in the air conditioning apparatus of the present invention, the rectifier 140 is connected to the winding coil 130, and the energy storage device 150 is connected to the rectifier 140, on one hand, the rectifier 140 can convert the ac power output by the winding coil 130 into dc power for supplying to the dc power utilization unit; on the other hand, the electric energy output by the winding coil 130 can also be stored in the energy storage device 150, that is, the energy storage device 150 is charged, so as to supply power to the electricity utilization unit when electricity is needed, and since the energy storage device 150 needs to convert the alternating current into the direct current during the charging process and then charges, the rectifier 140 can also function as a charger.
