Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an integrated motor fan and a fan coil unit. Background Art

[0002] The current fan coil unit includes a motor and a fan, and the two components of the fan and the motor need to be connected to operate normally. The motor is located on one side of the fan, and the return air of the fan needs to enter from both sides of the fan. Therefore, the motor has a certain influence on the return air efficiency of the fan. The greater the air volume, the greater the influence on the return air efficiency of the fan, and the motor speed needs to be increased. Correspondingly, the motor temperature rise will be greater, the efficiency will be lower, and the motor life will also be lower. At the same time, when designing the body shell of the fan coil unit, the motor needs to be considered, so the body size of the fan coil unit is designed to be larger, occupying a large space during installation and having a high production cost. Summary of the Utility Model

[0003] Based on this, it is necessary to provide an integrated motor fan and a fan coil unit for the above problems.

[0004] The technical solution is as follows:

[0005] On the one hand, an integrated motor fan is provided, including:

[0006] A volute;

[0007] A wind blade rotatably installed in the volute. The wind blade includes a conductive blade, and a first conductive frame and a second conductive frame spaced apart. The number of the conductive blades is at least one, and each of the conductive blades is circumferentially spaced apart along the first conductive frame. Both ends of each of the conductive blades are respectively electrically connected to the first conductive frame and the second conductive frame, so that the first conductive frame, the second conductive frame and each of the conductive blades cooperate to form a rotor structure;

[0008] A stator structure installed in the volute and configured to drive the rotor structure to rotate when it is in an energized state.

[0009] When the integrated motor fan in the above embodiments is in use, when the stator structure is powered on, while the stator structure generates a rotating magnetic field, induced currents will be generated in each conductive blade. The conductive blades with induced currents are subjected to the Ampere force in the magnetic field, causing the fan blades to rotate and supply air in the volute. The integrated motor fan in the present application makes full use of the existing structure of the fan, enabling the fan blades to retain their original functions while also serving as the rotor in the existing motor. As a result, the motor and the fan are integrated into one, reducing related structures such as the motor, eliminating the need for complex and high-requirement bearings, etc. The size of the integrated motor fan is reduced, the production cost is lowered, and the production efficiency is improved. In addition, the stator structure is installed in the volute without a separate single machine, overcoming the influence of the motor on the air return efficiency of the fan, increasing the air return space of the fan, reducing the air return resistance, improving the air supply efficiency, reducing the rotational speed, and lowering the energy consumption and noise of the integrated motor fan.

[0010] The technical solution will be further described below:

[0011] In one of the embodiments, the stator structure includes a coil, and the coil is encapsulated in the volute. In this way, while the volute retains its original function, it also serves as the stator core and the machine base in the existing motor, reducing related structures such as the motor, lowering the production cost of the integrated motor fan, and improving its production efficiency.

[0012] On the other hand, a fan coil unit is provided, which includes a body housing provided with an air flow channel and the above-mentioned integrated motor fan. The volute is installed on the body housing so that the air outlet of the volute is communicated with the air flow channel.

[0013] When the fan coil unit in the above embodiments is in use, when the stator structure is powered on, while the stator structure generates a rotating magnetic field, induced currents will be generated in each conductive blade. The conductive blades with induced currents are subjected to the Ampere force in the magnetic field, causing the fan blades to rotate in the volute and supply air to the air flow channel. The integrated motor fan in the present application makes full use of the existing structure of the fan, enabling the fan blades to retain their original functions while also serving as the rotor in the existing motor. As a result, the motor and the fan are integrated into one, reducing related structures such as the motor, eliminating the need for complex and high-requirement bearings, etc. The size of the integrated motor fan is reduced, the production cost is lowered, and the production efficiency is improved. In addition, the stator structure is installed in the volute without a separate single machine, overcoming the influence of the motor on the air return efficiency of the fan, increasing the air return space of the fan, reducing the air return resistance, improving the air supply efficiency, reducing the rotational speed, and lowering the energy consumption and noise of the fan coil unit.

In this way, the wind blade is installed on the body housing through the transmission shaft, so that the relative position between the wind blade and the volute is kept fixed, and the air is stably and reliably sent to the air flow channel, improving the stability and reliability of the fan coil unit. In addition, the support member can also play a supporting role, increasing the strength of the wind blade and improving the reliability of the integrated motor fan.

[0015] In one embodiment, the support member is arranged as a support plate provided with a central hole. At least one side of the support plate is provided with an annular flange. The inner side wall of the annular flange is connected to the inner side wall of the central hole to enclose and form the installation channel. The outer end of the support plate is insulatedly connected to each of the conductive blades. In this way, the annular flange can extend the length of the installation channel, increasing the driving cooperation area between the wind blade and the transmission shaft and improving the reliability of the fan coil unit.

[0016] In one embodiment, at least one reinforcing rib is further provided on the support plate. Each of the reinforcing ribs is arranged at intervals around the axis of the annular flange and is connected to the outer side wall of the annular flange. In this way, the reinforcing ribs can increase the strength of the wind blade, ensure that the wind blade can drive the transmission shaft to rotate synchronously, and improve the reliability of the fan coil unit.

[0017] In one embodiment, the wind blade further includes a bushing, which is installed in the installation channel and is in driving connection with the inner side wall of the installation channel. The transmission shaft passes through the bushing and is in driving connection with the inner side wall of the bushing.

[0034] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manner of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0035] As Figure 1 , Figure 2 and Figure 3 shown, in one embodiment, an integrated motor fan 10 is provided, which includes a volute 100, a wind blade 200, and a stator structure 300. Among them, the wind blade 200 is rotatably installed in the volute 100. The wind blade 200 includes conductive blades 210 and first and second conductive frames 220 and 230 that are spaced apart. The number of conductive blades 210 is at least one, and each conductive blade 210 is spaced apart along the circumferential direction of the first conductive frame 220. Both ends of each conductive blade 210 are electrically connected to the first conductive frame 220 and the second conductive frame 230 respectively, so that the first conductive frame 220, the second conductive frame 230, and each conductive blade 210 cooperate to form a rotor structure 400. The stator structure 300 is installed in the volute 100 and is configured to drive the rotor structure 400 to rotate when it is in an energized state.

[0036] For the integrated motor - blower 10 in the above - mentioned embodiments, during use, when the stator structure 300 is powered on, while the stator structure 300 generates a rotating magnetic field, induced currents will be generated in each conductive blade 210. And the conductive blades 210 with induced currents are acted upon by the Ampere force in the magnetic field, causing the wind blades 200 to rotate and supply air within the volute 100. The integrated motor - blower 10 in the present application makes full use of the existing structure of the blower, enabling the wind blades 200 to retain their original functions while also serving as the rotor in the existing motor. Thus, the motor and the blower are integrated into one, reducing related structures such as the motor, eliminating the need for complex and high - requirement bearings, etc. The size of the integrated motor - blower 10 is reduced, the production cost is lowered, and the production efficiency is improved. Additionally, the stator structure 300 is installed within the volute 100 without a separate single - machine, overcoming the influence of the motor on the air - return efficiency of the blower, increasing the air - return space of the blower, reducing the air - return resistance, improving the air - supply efficiency, reducing the rotational speed, and lowering the energy consumption and noise of the integrated motor - blower 10.

[0037] Specifically in this embodiment, the first conductive frame 220 and the second conductive frame 230 are coaxially arranged and are both arranged in a circular - ring shape. The number and arrangement of the conductive blades 210 can be flexibly designed and adjusted according to actual usage needs. The working principle of the rotor structure 400 is the same as that of the rotor in the existing motor. The working principle of the stator structure 300 is the same as that of the stator in the existing motor.

[0038] As Figure 1 and Figure 2 shown, optionally, the stator structure 300 includes a coil 310, and the coil 310 is plastic - encapsulated within the volute 100. In this way, while the volute 100 retains its original function, it also serves as the stator core and the machine base in the existing motor, reducing related structures such as the motor, lowering the production cost of the integrated motor - blower 10, and improving its production efficiency.

[0039] Among them, the arrangement of the coil 310 is the same as that of the stator coil in the existing motor. Specific arrangement methods such as the number of poles, the number of slots, and the number of coils 310 can be designed and adjusted according to actual needs. In other embodiments, the coil 310 can also be installed within the volute 100 by other methods such as in - embedding.

[0040] As Figure 2 and Figure 4 shown, in one embodiment, a fan - coil unit 1 is provided, which includes a body housing 20 provided with an air - flow channel 21 and the integrated motor - blower 10 in any of the above - mentioned embodiments. The volute 100 is installed on the body housing 20 so that the air - outlet 110 of the volute 100 is communicated with the air - flow channel 21.

[0041] In the fan coil unit 1 in the above embodiments, during use, when the stator structure 300 is powered on, while the stator structure 300 generates a rotating magnetic field, induced currents will be generated in each conductive blade 210. The conductive blade 210 with the induced current is subjected to the Ampere force in the magnetic field, causing the wind blade 200 to rotate in the volute 100 and send air to the air flow channel 21. The fan coil unit 1 in this application makes full use of the existing structure of the fan, enabling the wind blade 200 to retain its original function while also serving as the rotor in the motor. Thus, the motor and the fan are integrated into one, reducing related structures such as the motor, eliminating the need for complex and high - requirement bearings, etc. The size of the integrated motor - fan 10 is reduced, the production cost is lowered, and the production efficiency is improved. In addition, the stator structure 300 in the motor is installed in the volute 100 without a separate single - machine, overcoming the influence of the motor on the air - return efficiency of the fan, increasing the air - return space of the fan, reducing the air - return resistance, improving the air - supply efficiency, reducing the rotational speed, and reducing the energy consumption and noise of the fan coil unit 1.

[0042] Among them, the volute 100 can be installed on the body shell 20 by screwing, clamping, welding or other means.

[0043] As Figure 3 and Figure 4 shown, further, the wind blade 200 further includes a support member 240. The support member 240 is disposed at intervals between the first conductive frame 220 and the second conductive frame 230 and is insulatedly connected to each conductive blade 210. The support member 240 is provided with an installation channel 241 coaxially arranged with the first conductive frame 220. The fan coil unit 1 further includes a transmission shaft 30 rotatably installed on the body shell 20. The transmission shaft 30 passes through the installation channel 241 and is in transmission cooperation with the inner side wall of the installation channel 241. In this way, the wind blade 200 is installed on the body shell 20 through the transmission shaft 30, keeping the relative position between the wind blade 200 and the volute 100 fixed and stably and reliably sending air to the air flow channel 21, improving the stability and reliability of the fan coil unit 1. In addition, the support member 240 can also play a supporting role, increasing the strength of the wind blade 200 and improving the reliability of the integrated motor - fan 10.

[0044] Specifically in this embodiment, the support member 240 is made of an insulating material. The first conductive frame 220, the second conductive frame 230 and the conductive blades 210 are all made of a metal material with good conductivity. The support member 240 can be insulatedly connected to the conductive blade 210 by screwing, clamping, plugging or other means. The two ends of the conductive blade 210 can be correspondingly conductively connected to the first conductive frame 220 and the second conductive frame 230 by screwing, clamping, welding or other means. In other embodiments, the wind blade 200 can also be rotatably installed on other components such as the volute 100 through a connecting member (such as a connecting bracket).

[0045] AsFigure 3 As shown, optionally, the support member 240 is provided as a support plate 243 having a central hole 242. At least one side of the support plate 243 is provided with an annular flange 244. The inner side wall of the annular flange 244 is connected to the inner side wall of the central hole 242 to enclose and form an installation channel 241. The outer end of the support plate 243 is insulatedly connected to each conductive blade. In this way, the annular flange 244 can extend the length of the installation channel 241, increasing the transmission cooperation area between the wind blade 200 and the transmission shaft 30, and improving the reliability of the fan coil unit 1.

[0046] As Figure 3 shown, specifically in this embodiment, the support plate 243 is further provided with at least one reinforcing rib 245. Each reinforcing rib 245 is arranged at intervals around the axis of the annular flange 244 and is connected to the outer side wall of the annular flange 244. In this way, the reinforcing rib 245 can increase the strength of the wind blade 200, ensure that the wind blade 200 can drive the transmission shaft 30 to rotate synchronously, and improve the reliability of the fan coil unit 1.

[0047] Among them, the number and shape of the reinforcing ribs 245 can be flexibly adjusted according to actual use needs. Specifically in this embodiment, the support plate 243, the annular flange 244 and the reinforcing ribs 245 are made by integral molding.

[0048] As Figure 3 and Figure 4 shown, in one embodiment, the wind blade 200 further includes a bushing 250. The bushing 250 is installed in the installation channel 241 and is in driving connection with the inner side wall of the installation channel 241. The transmission shaft 30 passes through the bushing 250 and is in driving connection with the inner side wall of the bushing 250. In this way, the wind blade 200 can be fixed to the transmission shaft 30 through the bushing 250, improving the convenience of assembling the fan coil unit 1.

[0049] Specifically in this embodiment, the bushing 250 is in interference fit with the installation channel 241. The bushing 250 is fixed to the transmission shaft 30 through a key-spline structure.

[0050] As Figure 4 shown, optionally, the fan coil unit 1 further includes two mounting brackets 40. The two mounting brackets 40 are arranged at intervals at both ends of the transmission shaft 30 and are correspondingly rotationally connected to both ends of the transmission shaft 30. The two mounting brackets 40 are both fixed to the body housing 20. In this way, the mounting brackets 40 can play a role in supporting and limiting the transmission shaft 30, ensuring that the wind blade 200 on the transmission shaft 30 can stably and reliably rotate and supply air in the volute 100, and improving the reliability of the fan coil unit 1.

[0051] Among them, the number of the mounting brackets 40 can be flexibly adjusted according to actual usage requirements. The mounting brackets 40 can be fixed to the body housing 20 by screwing, clamping, welding or other means. The mounting brackets 40 can be rotatably connected to the transmission shaft 30 correspondingly through bearings.

[0052] Among them, the number of the integrated motor-fans 10 can be flexibly adjusted according to actual usage requirements.

[0053] As Figure 4 shown, in one embodiment, there is at least one integrated motor-fan 10, and the integrated motor-fans 10 are arranged at intervals along the axial direction of the transmission shaft 30. The transmission shaft 30 passes through the mounting channels 241 in each integrated motor-fan 10 and is in driving cooperation with the inner side walls of each mounting channel 241.

[0054] The fan coil unit 1 in this application (hereinafter referred to as the fan coil unit of this application) and the fan coil unit with a separately arranged motor and fan in the prior art (hereinafter referred to as the prior fan coil unit) are respectively subjected to simulation and simulation tests. On the premise of the same size, the same number of fans, and the same rotational speed, the comparison data of the air volume, return air resistance, and fan efficiency are shown in the above table:

[0055]

[0056] It can be seen from the above data that, compared with the prior fan coil unit, the fan coil unit of this application has a significant increase in both air volume and fan efficiency, and a significant decrease in return air resistance. Under the same conditions, the fan rotational speed in the fan coil unit of this application can be reduced, so the energy consumption is reduced, the noise is also reduced, and the comfort is improved. At the same time, under the same conditions, the size of the body housing 20 can be reduced, and the production cost can be reduced.

[0057] In other embodiments, the fan coil unit 1 further includes at least one ordinary fan. Each ordinary fan and each integrated motor-fan 10 are sleeved on the transmission shaft 30 at intervals and are in driving connection with the transmission shaft 30. In this way, the integrated motor-fans 10 can be used in cooperation with the ordinary fans. The production cost of the fan coil unit 1 is reduced, the structure is simple, the air supply efficiency is high, and it is energy-saving.

[0058] As Figure 4 shown, in one embodiment, the fan coil unit 1 further includes a surface cooler 50, and the surface cooler 50 is installed at the air flow channel 21. In this way, after the integrated motor-fan 10 is powered on and operates, the integrated motor-fan 10 sends air to the air flow channel 21, and the air is sent into the room after passing through the surface cooler 50 through which cold water or hot water passes, so as to realize cooling or heating of the room.

[0059] Among them, the surface cooler 50 can be installed inside the air flow channel 21 or at the outlet of the air flow channel 21. Specifically in this embodiment, the air flow channel 21 extends along the axial direction of the transmission shaft 30.
