[0002] With the progress of society and the development of science and technology, various household appliances are widely used in people's lives. These household appliances have different functions, effectively improving people's quality of life and bringing great convenience to people's lives. As the core structure of many household appliances, the motor, a power component, plays an important role in the performance of household appliances.

[0003] As people's requirements for household appliances gradually increase, the performance requirements for motors are also increasing. At the same time, in order to control the production cost of household appliances, the material cost of motors is further compressed, which leads to the number of structural parts that determine the core performance of motors being compressed as much as possible. In order to obtain the target performance, the motor power and motor heat generation are significantly increased, which brings about the problem of excessive motor temperature rise, and thus puts forward higher requirements for the heat dissipation effect of motors. However, as the internal structure of household appliances becomes increasingly complex and the number of internal electrical components gradually increases, the heat dissipation capacity of motors is further deteriorated. Summary of the invention

[0004] Based on this, it is necessary to provide a motor mounting housing, a drive structure and an electrical device to address the problem of poor heat dissipation of the motor.

[0011] A driving structure comprises the above-mentioned motor mounting housing, and the driving structure also comprises a motor, wherein the motor is accommodated in the motor accommodating cavity of the motor mounting housing.

[0012] In one of the embodiments, a top heat dissipation space is formed between an end wall of the motor and the top wall of the housing, and the top heat dissipation port and the side heat dissipation port are respectively connected to the top heat dissipation space.

[0013] In one of the embodiments, a plurality of motor heat dissipation holes are formed on one end wall of the motor facing the top wall of the housing, and all of the motor heat dissipation holes surround the orthographic projection of the edge of the top heat dissipation port on the motor.

Compared with the motor mounting housing in the prior art that only has heat dissipation ports on the top and the front, the motor mounting housing in the present application has heat dissipation ports on the top, the front and the sides, thereby increasing the heat dissipation area and enhancing the heat dissipation capacity of the motor mounting housing. Without increasing the cost, power and noise of the motor, the temperature of the motor is effectively reduced, thereby avoiding the impact on the performance of the motor due to excessive temperature.

[0039] See also Figure 1 and Figure 2 The embodiment of the present application provides an electrical device 100 provided with a drive structure 40. The following takes the electrical device 100 as a tower fan as an example to illustrate the structure of the drive structure 40 in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the electrical device 100 can also be specifically other devices equipped with a drive structure 40, which is not limited here.

[0040] The electrical device 100 includes a main body 20 and a driving structure 40 disposed at one end of the main body 20. When the electrical device 100 is placed on the ground, the driving structure 40 is located at the bottom of the main body 20. The main body 20 includes a housing 21, an air duct assembly 23, and a crossflow wind wheel 25. The three are coaxially arranged, and the air duct assembly 23 is located between the crossflow wind wheel 25 and the housing 21. The crossflow wind wheel 25 is connected to the driving structure 40 in a transmission manner so as to rotate relative to the air duct assembly 23 under the drive of the driving structure 40, thereby generating a directional airflow to cool the external environment. It can be understood that the specific structure of the main body 20 is not limited thereto and can be set as required.

[0041] like Figures 3 to 5 As shown, the driving structure 40 includes a motor mounting housing 41 and a motor 43. The motor mounting housing 41 is a hollow shell-like structure, including a housing top wall 412 and housing side walls extending in the same direction from the edge of the housing top wall 412, and the housing side walls surround the housing top wall 412 in the circumferential direction to form a motor accommodating cavity 41a together with the housing top wall 412, and the motor 43 is accommodated in the motor accommodating cavity 41a.

[0042] As described in the background art, the heat dissipation capacity of a motor is related to the overall performance of an electrical device, and existing solutions to the heat dissipation of a motor can be roughly divided into the following three types.

[0043] The first is active heat dissipation, such as adding cooling blades inside the motor. When the motor shaft rotates, the blades can be driven to rotate synchronously, converting the motor's kinetic energy into wind energy to remove the heat, or setting a cooling device near the motor, such as a cooling fan, to remove the heat generated by the motor. However, the setting of cooling blades and cooling fans significantly increases material costs and energy consumption, and increases the risk of noise.

[0044] The second is passive heat dissipation, which leaves as much heat dissipation space as possible for the motor in terms of structure. The motor achieves cooling through its own radiation heat dissipation. Although this solution will not increase production costs, the heat dissipation effect depends to a large extent on the external structure of the motor, so it cannot guarantee a good heat dissipation effect.

[0045] The third method is to optimize the motor structure, such as the thickness of the motor silicon steel sheet, so that the heat generated by the motor is reduced under the premise of the same load and output power, but this method significantly increases the manufacturing cost of the motor.

[0046] It can be seen that although the existing solutions for solving the heat dissipation of the motor improve the heat dissipation effect of the motor to a certain extent, they will also lead to further increase in cost, and even increase energy consumption and generate noise.

[0047] For the above technical issues, please refer to Figures 3 to 5The top wall 412 of the motor mounting shell 41 of the present application is provided with a top heat dissipation port 412a, and the top heat dissipation port 412a is used to connect the motor accommodating cavity 41a with the external atmosphere. The side wall of the shell is provided with a front heat dissipation port 414a, and the front heat dissipation port 414a is used to connect the motor accommodating cavity 41a with the external atmosphere. The side wall of the shell is also provided with at least one side heat dissipation port 414b connected with the motor accommodating cavity 41a.

[0048] In this way, the motor 43 is accommodated in the motor accommodating cavity 41a, and part of the heat generated by the motor 43 during operation flows out of the motor accommodating cavity 41a through the top heat dissipation port 412a, part of the heat flows out of the motor accommodating cavity 41a through the front heat dissipation port 414a, and part of the heat flows out of the motor accommodating cavity 41a through the side heat dissipation port 414b. Compared with the motor mounting housing 41 in the prior art, which only has heat dissipation ports at the top and the front, the motor mounting housing 41 in the present application has heat dissipation ports at the top, the front and the side, thereby increasing the heat dissipation area to a greater extent, enhancing the heat dissipation capacity of the motor mounting housing 41, and effectively reducing the temperature of the motor 43 without increasing the cost, power and noise of the motor 43, thereby avoiding the influence of excessive temperature on the performance of the motor 43.

[0049] Specifically, Figure 6 As shown, the top heat dissipation port 412a and the front heat dissipation port 414a are directly connected to the external environment, so the heat flowing out from the top heat dissipation port 412a and the front heat dissipation port 414a directly enters the external environment. Figures 7 to 10 As shown, the side heat dissipation vent 414b is connected to the main body 20 but not directly connected to the external environment, so the heat flowing out of the side heat dissipation vent 414b enters the main body 20 to be dissipated through the lower temperature main body 20. Specifically in one embodiment, the side heat dissipation vent 414b is connected to the gap between the air duct assembly 23 and the housing 21.

[0050] That is to say, in the present application, part of the heat generated by the motor 43 directly enters the external environment, and the other part is dissipated through the main body 20, and the two heat dissipation methods work together to achieve a good heat dissipation effect. Furthermore, in some embodiments, the front heat dissipation port 414a plays a major role in heat dissipation, and most of the heat generated by the motor 43 flows directly into the external environment through the front heat dissipation port 414a, and the side heat dissipation port 414b plays an auxiliary role in heat dissipation. When the heat dissipation to the outside by using the front heat dissipation port 414a reaches the temperature reduction limit, the heat dissipation to the inside of the main body 20 by using the side heat dissipation port 414b can further reduce the temperature of the motor 43.

[0051] Please review Figures 3 to 5Since the air with high temperature flows upward due to its small specific gravity, as a preferred embodiment, the side heat dissipation port 414b is located on the side where the shell side wall is connected to the shell top wall 412, so the heat generated by the motor 43 flows upward toward the shell top wall 412, and then flows out through the top heat dissipation port 412a and the side heat dissipation port 414b, thereby forming a chimney effect so that the external low-temperature air continuously enters the motor accommodating cavity 41a.

[0052] Further, in some embodiments, the side wall of the housing is provided with two side heat dissipation openings 414b, which are spaced apart and located at opposite sides of the front heat dissipation opening 414a, so that the heat generated by the motor 43 can flow out from the two side heat dissipation openings 414b at the same time. It can be understood that the number and arrangement of the side heat dissipation openings 414b are not limited thereto, and can be arranged according to factors such as the shape of the motor mounting housing 41 and the main body 20 to meet different heat dissipation requirements.

[0053] In the following embodiments, the width direction of the motor mounting housing 41 is defined as the first direction (i.e. Figure 3 The length direction of the motor mounting housing 41 is the second direction (i.e. Figure 3 The height direction of the motor mounting housing 41 is the third direction (i.e. Figure 3 (Z direction in the figure), the first direction, the second direction and the third direction intersect each other. As a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other.

[0054] Please continue reading Figures 3 to 5 There is a gap between the top wall 412 of the housing and one end wall of the motor 43 to form a top heat dissipation space, and a circular top heat dissipation port 412a is provided at the center of the top wall 412 of the housing. In this way, the top heat dissipation port 412a and the side heat dissipation port 414b are respectively connected to the top heat dissipation space, and the heat generated by the motor 43 flows upward into the top heat dissipation space, and then flows out from the top heat dissipation port 412a and the side heat dissipation port 414b.

[0055] Furthermore, a plurality of screw columns 416 and a plurality of reinforcing ribs 418 are convexly provided along the third direction on one side of the housing top wall 412 facing the motor accommodating cavity 41a, and all screw columns 416 are arranged at intervals around the circumference of the top heat dissipation port 412a, and each reinforcing rib 418 connects two adjacent screw columns 416 to increase the structural strength of the screw columns 416, and the motor 43 can be fixed to the screw columns 416 by screws. It can be understood that the fixing method of the motor 43 is not limited to this, and can be set as needed to meet different requirements. As a preferred embodiment, a notch can be opened on the reinforcing rib 418 to allow airflow to flow through, thereby reducing the flow resistance of hot air.

[0056] In some embodiments, a plurality of motor heat dissipation holes are provided on one end wall of the motor 43 facing the top wall 412 of the housing, and all the motor heat dissipation holes are arranged around the orthographic projection of the edge of the top heat dissipation opening 412a on the motor 43. That is to say, all the motor heat dissipation holes are arranged around the central axis of the motor 43 to enclose a circular area, the diameter of the top heat dissipation opening 412a is smaller than the diameter of the aforementioned circular area, and the orthographic projection of the edge of the top heat dissipation opening 412a on the motor 43 is located within the circular area, thereby preventing water droplets dripping from the main body 20 from entering the heat dissipation holes of the motor 43. It can be understood that the shape, number and position of the top heat dissipation holes can be set as needed to meet different heat dissipation requirements.

[0057] In some embodiments, in order to prevent the crossflow impeller 25 from shaking when running at high speed, thereby causing the main body 20 to shake or make noise, a flexible material such as rubber is provided at the bottom of the crossflow impeller 25. When the whole machine falls, the crossflow impeller 25 will sink as a whole due to the huge inertia, and because the bottom of the crossflow impeller 25 is provided with a flexible material, the crossflow impeller 25 will deform downward, resulting in the risk that the top of the crossflow impeller 25 will fall out of the installation hole.

[0058] In order to solve the above problem, the distance h between the top wall 412 of the motor mounting housing 41 of the present application and the bottom of the crossflow impeller 25 is set to 4.6 mm (e.g. Figure 1 As shown in the figure), on the one hand, it can limit the crossflow impeller 25 when the whole machine falls to prevent the top of the crossflow impeller 25 from falling out, and on the other hand, it can maximize the distance between the housing top wall 412 and the motor 43, and indirectly strengthen the distance between the housing side wall and the motor 43, thereby further improving the heat dissipation effect. It can be understood that the specific value of the distance h between the housing top wall 412 of the motor mounting housing 41 and the bottom of the crossflow impeller 25 is not limited to this, and can be set as needed to meet different requirements.

[0059] like Figures 3 to 5 As shown, the side wall of the housing includes a front wall 4141, a rear wall 4143, a left side wall 4145 and a right side wall 4147. The front wall 4141, the left side wall 4145, the rear wall 4143 and the right side wall 4147 are connected end to end in sequence, and the front wall 4141 and the rear wall 4143 are spaced apart in the first direction, and the left side wall 4145 and the right side wall 4147 are spaced apart in the second direction and connected between the front wall 4141 and the rear wall 4143. The rear wall 4143 is not provided with a heat dissipation port due to waterproof requirements, the front heat dissipation port 414a is provided on the front wall 4141, and the two side heat dissipation ports 414b are respectively located on the left side wall 4145 and the right side wall 4147 on the side close to the front wall 4141.

[0060] Furthermore, the front heat dissipation opening 414a includes a plurality of heat dissipation holes, all of which are arranged at intervals on the front wall 4141, which has a large heat dissipation area while meeting the strength and protection requirements. Since the front heat dissipation opening 414a has a large heat dissipation area and is directly connected to the outside atmosphere, it plays a major role in heat dissipation. It can be understood that the shape, number and arrangement of the heat dissipation holes are not limited and can be set as needed to meet different heat dissipation requirements.

[0061] The above-mentioned motor mounting housing 41, drive structure 40 and electrical equipment 100, on the basis of increasing the top heat dissipation space of the motor mounting housing 41 to the maximum, simultaneously provide a top heat dissipation port 412a, a front heat dissipation port 414a and a side heat dissipation port 414b on the motor mounting housing 41 to form a three-dimensional heat dissipation structure. While utilizing the outside air for direct heat dissipation, the main body 20 with a lower temperature is utilized for auxiliary heat dissipation, thereby maximizing the discharge speed of the heat generated by the motor 43. Without increasing the cost of the motor 43 and the cost, noise and power of the entire electrical equipment 100, the heat dissipation capacity of the electrical equipment 100 is enhanced, so that the performance of the motor 43 can be further improved, and ultimately the overall performance of the electrical equipment 100 is improved.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
