[0035] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "axial", "radial", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of this utility model, if there are descriptions of "first", "second", etc., they are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, it should be noted that terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0040] The vibration noise of a drum washing machine's drive motor depends largely on the motor's sealing performance. Generally, a motor consists of a stator, rotor, front cover, and rear cover. The front and rear covers are assembled with the stator and supported by the rotor. Due to the gaps between the front and rear covers and the stator, noise can easily be transmitted through these gaps. Furthermore, when there are many assembly parts, resonance is easily excited, resulting in increased noise. Furthermore, as the number of assembly parts increases, the overall cost of the machine also increases.

[0041] To solve the above problems, refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a motor 1000 suitable for a washing machine or other washing equipment. The motor 1000 of a drum washing machine is used as an example for detailed description below.

[0042] Reference Figure 1 and Figure 3 As shown, the motor 1000 of the embodiment of the present invention includes a stator 100, a rotor 200 and an end cover 300, wherein the stator 100 includes a stator core 110 and a plastic shell 120, and the plastic shell 120 is molded on the stator core 110 through a plastic packaging process, so that the stator core 110 and the plastic shell 120 form an integrated structure. In the embodiment, the stator 100 is also called a plastic-encapsulated stator. The rotor 200 is rotatably connected to the stator 100. An open port 121 is provided at the front end of the plastic shell 120. The stator core 110 is annular. The port 121 is connected to the inner cavity of the stator core 110. The rotor 200 can be assembled into the stator core 110 through the port 121; the end cover 300 covers the port 121. The end cover 300 is connected to the plastic shell 120. The end cover 300 can be understood as the front end cover 300 of the motor 1000, and the front end of the rotor 200 is supported by the front end cover 300.

[0043] Reference Figure 3 As shown, rotor 200 includes a rotor core 210 and a rotating shaft 220. Rotating shaft 220 is disposed on rotor core 210. The front end of rotating shaft 220 passes through front end cover 300 to form a driving end 221. Front end cover 300 is connected to plastic housing 120 via bolts 700. A front bearing 222 is mounted on front end cover 300 to support the front end of rotating shaft 220.

[0044] It should be noted that, in some embodiments, a rear end cover 300 (not shown in the drawings) may be provided at the rear end of the plastic shell 120, and the plastic shell 120 is plastic-wrapped on the rear end cover 300, so that the rear end cover 300 and the plastic shell 120 are integrally formed, and a rear bearing 223 is installed on the rear end cover 300, which supports the rear end of the rotating shaft 220 through the rear bearing 223, so that both ends of the rotor 200 are supported, so that the rotor 200 can operate stably in the stator 100.

[0045] Reference Figure 1 、 Figure 3 and Figure 4 As shown, the motor 1000 further includes an electronic control board 500. A mounting structure 400 is provided at the rear end of the plastic housing 120. The mounting structure 400 is used to accommodate the electronic control board 500. It will be appreciated that since the plastic housing 120 is formed on the rotor core 210 by injection molding, in this embodiment, the mounting structure 400 is integrally injection-molded with the plastic housing 120. This simplifies the assembly structure of the electronic control board 500 and the rotor 200, reduces the number of assembly components, and facilitates assembly.

[0046] In the related art, the motor's electronic control board is installed in a separate electronic control box, which is then mounted on the motor. This means that the electronic control box and motor are separate structures, requiring additional components to securely connect the electronic control box and motor. Furthermore, there is an assembly gap between the electronic control box and the motor, which is not conducive to noise reduction. In the embodiment of the present invention, however, the mounting structure 400 and the plastic housing 120 are integrally formed, reducing the assembly gap and the number of electronic control boxes and corresponding assembly parts. This simplifies assembly, makes motor 1000 less likely to excite resonance, effectively reduces vibration noise, and helps reduce the cost of motor 1000.

[0047] It should be noted that the mounting structure 400 in the embodiment can function as an electric control box in the related art, protecting the electric control box, and can also be a bracket, fixing platform, or other structure for fixing the electric control board 500. It is understood that because the mounting structure 400 is formed at the rear end of the plastic housing 120, when the rear end cover 300 is installed, the mounting structure 400 can cover the rear end cover 300, forming a closed structure at the rear end of the plastic housing 120. This can reduce the assembly gap at the rear end of the motor 1000, improve the sealing performance of the motor 1000, and thus reduce the transmission of noise through the assembly gap, thereby achieving a noise reduction effect.

[0048] Of course, in some embodiments, since the mounting structure 400 is formed at the rear end of the stator core 110, the rear end of the stator core 110 forms a closed structure, so that the rear bearing 223 can also be directly installed on the side of the mounting structure 400 facing away from the electronic control board 500. For example, a bearing chamber is formed on the side of the mounting structure 400 facing the stator core 110, and the bearing chamber and the mounting structure 400 are integrally formed. The rear bearing 223 is installed in the bearing chamber, so that the rear end cover 300 component can be removed, further simplifying the structure.

[0049] It can be understood that the embodiment adopts a structure in which the mounting structure 400 and the stator 100 are integrally formed, which not only reduces the number of assembly parts of the motor 1000 as a whole, but also reduces the assembly gap, making it less likely for the motor 1000 to excite resonance, thereby reducing the generation of resonance and helping to reduce vibration noise.

[0050] It can be understood that in the embodiment of the present invention, the stator 100 also includes a winding, which is wound on the stator core 110, and the electronic control board 500 is electrically connected to the winding. The motor 1000 is connected to the circuit of the washing machine through the electronic control board 500, and the power supply and signal transmission are realized for the motor 1000, thereby controlling the operation of the motor 1000.

[0051] Considering that the temperature rise of motor 1000 is primarily reflected in the temperature rise of stator 100 windings, and because there are assembly gaps between assembly parts, the air in the assembly gaps acts as a thermal resistor. When there are many assembly parts and assembly gaps, heat dissipation from stator 100 windings is detrimental. The assembly gaps reduce the heat dissipation effect, hindering the stable operation of motor 1000. The embodiment of the present invention, by adopting the above-described structure, can reduce the number of assembly parts and assembly gaps, thereby reducing the air thermal resistance. Heat can be transferred to mounting structure 400 for dissipation, which helps accelerate the heat dissipation of the windings, thereby improving the heat dissipation effect and facilitating the stable operation of motor 1000.

[0052] It should be noted that the material used for the plastic shell 120 of the embodiment is bulk molding compound (BMC), which is lower in cost than the motor 1000 in the related art that uses aluminum or other materials for the shell. The plastic packaging process facilitates the stator core 110, the plastic shell 120 and the mounting structure 400 to form an integrated structure, which is easy to process and has a stable and reliable structure, effectively reducing the number of assembly parts of the motor 1000 and further reducing the cost of the entire machine.

[0053] Reference Figure 1 As shown, the end cap 300 can be connected to the plastic housing 120 via bolts 700. Specifically, a through hole is formed in the plastic housing 120 along the axial direction of the stator 100. The bolts 700 pass through the end cap 300 and are fixedly connected to the plastic housing 120, thereby securing the end cap 300. In the embodiment, the end cap 300 is fixed by three bolts 700, ensuring a stable and secure assembly of the end cap 300. Of course, this is merely an example, and the number of bolts 700 is not limited to three, but may also be four, five, or more. The connecting members are also not limited to bolts 700, and may also be fixed by rivets or other methods, depending on actual requirements.

[0054] Reference Figure 3 and Figure 4As shown, in some embodiments, the mounting structure 400 includes a box body 410 formed at the rear end of the plastic housing 120 and having a generally rectangular shape. Because the box body 410 and the plastic housing 120 are integrally formed, the electric control board 500 can be directly mounted within the box body 410. Compared to a structure in which the electric control box is separate from the motor 1000, there is no need to mount the electric control box on the motor 1000 after the electric control board 500 is mounted. This simplifies the mounting structure 400 and improves assembly efficiency. Furthermore, no gap is formed between the box body 410 and the stator 100, thereby reducing assembly clearance. The specific dimensions of the box body 410 can be set according to the dimensions of the electric control board 500 so that the electric control board 500 can be accommodated within the box body 410, thereby protecting the electric control board 500.

[0055] It can be understood that the box body 410 is formed as a whole with the plastic shell 120, and the box body 410 protrudes from the rear end of the plastic shell 120 in the direction away from the stator 100. The box body 410 is made of plastic. The electric control board 500 can be fixedly connected to the box body 410 by screws, snap connections, etc., so that the electric control board 500 is fixedly connected to the motor 1000. For example, the bottom wall of the box body 410 can be integrally formed with a screw hole, and the screw is passed through the electric control board 500 and fixedly connected to the screw hole, so that the electric control board 500 can be quickly fixed.

[0056] Of course, this is just an example, and the shape of the box body 410 is not limited to a rectangle, and can be a circle, a square, or other shapes.

[0057] Furthermore, since the electronic control board 500 needs to be connected to the windings, the windings must be electrically connected to the electronic control board 500 through the box body 410 via a conductive structure. Specifically, the windings are wound around the stator core 110, and the winding leads are connected to the conductive plates 413. Taking a three-phase winding as an example, each phase of the winding is welded to the conductive plates 413. The stator core 110, windings, and conductive plates 413 are encapsulated together through a plastic encapsulation process. The conductive plates 413 are then connected to the electronic control board 500. The conductive plates 413 are conductive metal sheets, thus achieving an electrical connection between the electronic control board 500 and the windings, and the structure is stable and reliable.

[0058] Combine Figure 4 It can be understood that, considering that the conductive piece 413 needs to be connected to the electronic control board 500, after the stator 100 and the box body 410 are injection molded, a slot 412 is formed on the bottom wall of the box body 410, and the conductive piece 413 is exposed in the slot 412. The electronic control board 500 can be connected to the conductive piece 413 by plugging. For example, the electronic control board 500 is provided with a plug connector that matches the slot 412, and the conductive piece 413 can be provided with two, three or more, which is specifically set according to the application requirements.

[0059] In some embodiments, in order to improve the connection stability between the electronic control board 500 and the conductive sheet 413, after the electronic control board 500 is inserted into the slot 412, the electronic control board 500 and the conductive sheet 413 can be fixed by welding to ensure that the electronic control board 500 and the conductive sheet 413 can maintain communication and are not easily loosened.

[0060] Continue to refer to Figure 3 and Figure 4 As shown, the box body 410 includes a peripheral edge 411 that protrudes from the rear end of the plastic housing 120 and forms a rectangular frame. It will be appreciated that because the box body 410 is integrally formed with the plastic housing 120 and is formed at the rear end of the plastic housing 120, the bottom wall of the box body 410 can cover the rear end of the stator core 110, forming a closed structure. The side of the box body 410 away from the bottom wall is open, through which the electronic control board 500 can be installed within the box body 410.

[0061] Combine Figure 2 As shown, in the embodiment, the motor 1000 also includes a cover body 600, and the cover body 600 is connected to the surrounding edge 411, so that the cover body 600 covers the opening structure. In this way, the cover body 600 and the surrounding edge 411 can cooperate to define an installation space 420, and the installation space 420 can accommodate the electronic control board 500, so that the electronic control board 500 will not be exposed, thereby improving the protection effect.

[0062] Specifically, if Figure 4 and Figure 5 As shown, the shape of the cover body 600 matches the shape of the surrounding edge 411. Screw holes are provided on the surrounding edge 411, and the screw holes are located at the corners of the frame. At the same time, openings corresponding to the screw holes are opened on the cover body 600. The cover body 600 is connected to the box body 410 by screws passing through the openings and the screw holes.

[0063] It should be noted that, in the embodiment, the cover body 600 is provided with a plurality of heat dissipation holes 610, which are in the shape of long strips and distributed along the surface of the cover body 600. Figure 1 and Figure 2 It can be understood that the cover 600 can cover the electric control board 500 after being assembled, and the heat generated by the electric control board 500 is dissipated outwards through the heat dissipation holes 610, thereby improving the heat dissipation efficiency of the electric control board 500.

[0064] In addition, the cover body 600 is made of plastic material, and the heat dissipation holes 610 and the cover body 600 are integrally formed by injection molding, which is easy to process and has low cost.

[0065] In some embodiments, the mounting structure 400 includes a plastic coating formed at the rear end of the plastic package housing 120 and wrapped around the electronic control board 500. Figure 1 and Figure 2 The difference between the illustrated embodiments is that the stator core 110 and the electronic control board 500 are injection molded together, so that a plastic layer can be formed and wrap the electronic control board 500 at the same time as the plastic package shell 120 is formed. There is no need to install the electronic control board 500 and the cover 600 after the stator 100 is injection molded, thereby simplifying the assembly structure and further reducing the cost of the entire machine.

[0066] Specifically, during assembly, the lead wires of the windings are first welded to the electric control board 500 through the conductive sheet 413, and then the stator core 110, the windings, and the electric control board 500 are plastic-sealed. In this way, the electric control board 500 can be completely wrapped in the plastic layer, and there is no need to add screws or other connecting parts to fix the electric control board 500, making assembly more convenient and quick.

[0067] It can be understood that, compared with the structure of the combination of the box body 410 and the cover body 600, the plastic-encapsulated shell 120 can reduce the number of assembly parts by forming a plastic layer in one piece, and the assembly gap is also reduced accordingly, which has better sealing performance in blocking vibration noise, better noise reduction effect, and is also beneficial to reducing thermal resistance and improving heat dissipation effect.

[0068] Of course, the plastic coating layer may be provided with heat dissipation holes 610, which help to accelerate the heat dissipation of the electronic control board 500 and improve the heat dissipation efficiency of the electronic control board 500. The specific form of the heat dissipation holes 610 can be found in Figure 1 and Figure 2 The heat dissipation hole 610 structure of the embodiment shown.

[0069] Reference Figure 1 and Figure 2 As shown, the outer wall of the plastic shell 120 is provided with a first mounting foot 130 and a second mounting foot 140, wherein two first mounting feet 130 are provided, and the two first mounting feet 130 are arranged at intervals and located at the front end of the plastic shell 120; one second mounting foot 140 is provided, and the second mounting foot 140 is located at the rear end of the plastic shell 120. The motor 1000 is connected to the washing machine through the first mounting foot 130 and the second mounting foot 140, so that the motor 1000 can be fixedly assembled in the washing machine and obtain stable support.

[0070] It is understood that the first mounting foot 130 and the second mounting foot 140 are integrally injection-molded with the plastic housing 120. That is, after the stator 100 is injection-molded, the first mounting foot 130, the second mounting foot 140, and the housing 410 are simultaneously formed. Since the motor 1000 needs to be mounted horizontally on the washing machine, that is, the axial direction of the rotating shaft 220 is arranged horizontally after the motor 1000 is installed, the first mounting foot 130 and the second mounting foot 140 are arranged on the same side of the motor 1000 to facilitate connection of the motor 1000 to the washing machine.

[0071] In the embodiment, the stator 100 adopts the above structure, and compared with the split structure of the mounting feet and the motor 1000, the number of assembly parts can be greatly reduced, the assembly efficiency of the motor 1000 is improved, the assembly gap is reduced, the possibility of exciting resonance is further reduced, the noise reduction effect is better, and the thermal resistance is also reduced, and the heat dissipation efficiency of the motor 1000 is improved.

[0072] Specifically, as shown by the direction of Figure 1 and Figure 2 As a reference, the first mounting feet 130 and the second mounting feet 140 are located at the lower side of the motor 1000, and the two first mounting feet 130 are arranged at intervals along the circumference of the plastic package shell 120, and the two first mounting feet 130 are respectively provided with a first connecting part 131, the first connecting part 131 extends along the radial direction of the stator 100, that is, the two first connecting parts 131 are respectively arranged in a direction away from the plastic package shell 120, and a first mounting hole 132 is arranged on the first connecting part 131, and the axial direction of the first mounting hole 132 is consistent with the axial direction of the rotating shaft 220.

[0073] It should be noted that in the embodiment, the second mounting feet 140 are in the form of a plug-in structure, specifically in the form of a flat, and the second mounting feet 140 are arranged in a direction away from the plastic package shell 120 along the axial direction of the stator 100, that is, the second mounting feet 140 protrude towards the rear side of the motor 1000. The first mounting feet 130 are also referred to as the front feet of the motor 1000, and the second mounting feet 140 are also referred to as the rear feet of the motor 1000.

[0074] It can be understood that the washing machine is provided with a connecting part corresponding to the first mounting feet 130 and a plug-in hole corresponding to the second mounting feet 140, and during assembly, the plug-in structure is directly inserted into the plug-in hole of the washing machine, and then the two first mounting feet 130 in front are connected to the connecting part of the washing machine, so that the motor 1000 is fixed. Specifically, the connecting part can be a connecting column, which can be directly buckled into the first mounting hole 132 of the first connecting part 131, so that the front and rear ends of the motor 1000 are fixed, and the installation is simple and fast. Of course, the connecting part is not limited to the connecting column, and the connecting part can satisfy the fixing through the first mounting hole 132, for example, it can also be fixed through a screw or other forms of parts; in addition, the shape of the plug-in structure is not limited to the flat, and it can also be set according to actual requirements.

[0075] Since the two first mounting feet 130 are located at the front end of the motor 1000 for support, and one second mounting foot 140 is located at the rear end of the motor 1000 for support, and the first mounting feet 130 and the second mounting feet 140 are located at the lower side of the motor 1000. In the embodiment, the positions of the first mounting feet 130 and the second mounting feet 140 are further optimized, specifically, in combination with Figure 1It can be understood that on the axial projection surface of the motor 1000 along the stator 100, the projection of the pin structure is located between the projections of the two first mounting holes 132. In this way, the two first mounting feet 130 and the one second mounting foot 140 are distributed non-linearly on the lower side of the motor 1000, specifically in a triangular distribution, and are located on the same plane, which is conducive to forming a stable support, making the installation of the motor 1000 more stable and reliable, and can greatly reduce the number of assembly parts, which has greater advantages in saving costs.

[0076] Of course, this is only an example, and the specific forms of the first mounting foot 130 and the second mounting foot 140 are not limited to the structures shown in the above embodiments. For example, the second mounting foot 140 can also be fixed by means of buckling or the like, and can also adopt the same structure as the first mounting foot 130, that is, the second mounting foot 140 can be connected to the connecting component of the washing machine through the mounting hole; in addition, the number of the second mounting feet 140 is not limited to one, and can also be two or more, for example, two pin structures can be provided for plugging with the washing machine.

[0077] Since the number and form of the mounting feet of the motor 1000 remain fixed after the first mounting foot 130 and the second mounting foot 140 are injection-molded with the plastic shell 120, there is a problem of low compatibility. For example, after the stator 100 is injection-molded, two first mounting feet 130 and one second mounting foot 140 are formed, that is, there are three mounting feet, which are only suitable for washing machines with mounting positions corresponding to the three mounting feet reserved, and are not compatible with washing machines that do not match the mounting feet.

[0078] Based on this, refer to Figure 6 As shown, in some embodiments of the present invention, the motor 1000 also includes a third mounting foot 800, and two third mounting feet 800 are provided. The two third mounting feet 800 are arranged at intervals along the circumference of the plastic shell 120 and are detachably connected to the rear end of the plastic shell 120. In this way, after the stator 100 is injection molded, two third mounting feet 800 can be added to the plastic shell 120, so that the motor 1000 has four mounting feet. In other words, the motor 1000 can be switched from three mounting feet to four mounting feet. In this way, the motor 1000 is compatible with washing machines with three mounting positions and four mounting positions, and has better compatibility to meet the needs of different installation methods.

[0079] Reference Figure 7 and Figure 8As shown, specifically, the two third mounting feet 800 are respectively connected to the plastic shell 120 by bolts 700, so that the third mounting feet 800 and the plastic shell 120 can be detachable, and the operation is easy; the two third mounting feet 800 are both connected to the lower side of the motor 1000, that is, they are located on the same side as the first mounting foot 130, and the two third mounting feet 800 are respectively provided with a second connecting part 810, and the second connecting part 810 is provided with a second mounting hole 811, and the second mounting hole 811 is used to connect to the connecting parts of the washing machine.

[0080] in, Figure 7 Showing the exploded state diagram of the two third mounting feet 800 and the motor 1000, Figure 8 The figure shows the two third mounting legs 800 assembled with the motor 1000. As can be seen, along the axial direction of the stator 100, the two third mounting legs 800, once installed, correspond one-to-one with the two first mounting legs 130. The second mounting holes 811 and the first mounting holes 132 are both arranged axially along the stator 100. When installing the motor 1000, first connect the two third mounting legs 800 at the rear end to the two connecting posts of the washing machine, then connect the two first mounting legs 130 at the front end to the other two connecting posts, making installation easier.

[0081] It should be noted that in this embodiment, the connection locations of the two third mounting feet 800 are located on either side of the second mounting foot 140, so that the second mounting foot 140 does not interfere with the assembly of the two third mounting feet 800. The second mounting foot 140 and the third mounting foot 800 are both located on the lower side of the box body 410, and the box body 410 and the mounting feet do not interfere with each other. This allows the box body 410, the first mounting foot 130, the second mounting foot 140, and the plastic housing 120 to be integrally formed, and additional mounting feet can be added according to application requirements, resulting in a reasonable layout design.

[0082] In addition, the number of the third mounting feet 800 is not limited to two, and one, three or more can be provided according to actual requirements; and the form of the third mounting feet 800 is not limited to Figure 7 and Figure 8 The structure shown may also be in the form of a latch structure, for example, connected to the plastic housing 120 via a detachable latch, so that the rear end of the motor 1000 may be provided with one, two or more latches.

[0083] Reference Figure 6 and Figure 7As shown, in this embodiment, motor 1000 further includes a connector. A boss 150 is formed on the outer peripheral wall of the plastic housing 120. Boss 150 is provided with a through-hole disposed axially along stator 100. Since end cap 300 is located at the front end of stator 100 and needs to be connected to plastic housing 120 via bolts 700, this embodiment utilizes connectors such as bolts 700 to penetrate the through-holes and securely fasten end cap 300 and third mounting foot 800, thereby improving assembly efficiency.

[0084] It can be understood that in the embodiment, the end cover 300 is fixed by three bolts 700, wherein the two bolts 700 on the lower side pass through the plastic shell 120 and are respectively connected to the two third mounting feet 800. In this way, the end cover 300 and the third mounting feet 800 can be quickly assembled into place, with higher assembly accuracy and better sealing, which is conducive to reducing the generation of vibration noise, and the overall assembly structure of the motor 1000 is also more stable and reliable.

[0085] An embodiment of the present invention also provides a washing device, which can be a washing machine or other washing appliances. Taking a drum washing machine as an example, the motor 1000 of the above embodiment is adopted, and the motor 1000 is installed in the drum washing machine. The motor 1000 is connected to the connecting parts or other fixed structures of the drum washing machine through the first mounting foot 130 and the second mounting foot 140.

[0086] A plastic-encapsulated shell 120 is formed on the stator core 110 through a plastic-encapsulation process. A mounting structure 400 is provided on the plastic-encapsulated shell 120 so that the mounting structure 400 and the plastic-encapsulated shell 120 form an integrally formed structure. The mounting structure 400 is used to accommodate the electronic control board 500, so that the electronic control board 500 and the stator 100 are assembled into an integral structure. In this way, one end of the stator 100 is assembled with the end cover 300, and the other end forms a closed structure through the mounting structure 400. This can reduce the assembly gap and the number of assembly parts between the electronic control board 500 and the stator 100, making it difficult for the motor 1000 to excite resonance, thereby effectively reducing the vibration noise of the washing machine.

[0087] Since the washing device adopts all the technical solutions of the motor 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described in detail here.

[0088] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
