Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The inventor finds that the heat dissipation efficiency of the heating element (such as a magnetron) is improved by increasing fan blades, increasing the rotating speed of a motor, fully coating the fan blades and adding an additional air guide component in the heat dissipation scheme of the heating element in the existing microwave oven, but the heat dissipation scheme has more defects. For example, if the number of fan blades is increased, the manufacturing cost of the fan is increased. If the rotating speed of the fan motor is increased, the requirement on the power of the motor is increased, and the cost is increased. If the air guide ring is completely coated outside the fan blade, the occupied space is large, the compatibility is poor, but eddy current is easily caused at the bottom of the fan blade with smaller space, and the air quantity is easily dissipated from the upper part of the fan blade, so that the heat dissipation effect of the fan blade on a heating component is influenced. If the air guide part is additionally arranged, the number of parts and the cost are increased, the occupied volume is increased, and the installation process is increased. If the work efficiency of the microwave oven is reduced, the work efficiency is reduced, the cooking time is prolonged, and the temperature cannot be raised to the preset temperature.
Referring to fig. 1 and 6, fig. 1 is a schematic perspective view of a fan assembly according to an embodiment of the present disclosure; fig. 6 is a partial perspective view of an embodiment of a microwave oven according to the present application.
An embodiment of the present application provides a fan assembly 10, and the fan assembly 10 is configured to be disposed in a microwave oven 200. The microwave oven 200 has a top 201 and a bottom 202 disposed opposite to each other. Wherein the bottom 202 of the microwave oven 200 is used for being placed on a workbench. Fan assembly 10 includes a support frame 120, a blade structure 11, and an air deflector 13. Fan blade structure 11 is disposed on support 120. The air deflector 13 is disposed on the bracket 120. The air guide plate 13 is located on a side of the fan blade structure 11 facing the top 201 of the microwave oven 200. The air deflector 13 is in the shape of an arc and partially surrounds the fan blade structure 11.
In the structure of the microwave oven 200, a heating component (for example, an inverter, a transformer, a magnetron, etc.) is usually disposed on the side of the air outlet 101 of the fan blade structure 11. Therefore, wind resistance exists at the air outlet 101 of the fan blade structure 11, and the wind blown out by the fan blade structure 11 can be diffused radially. The flow dissipation is particularly significant at the top 201 and left and right wings of fan blade structure 11 toward microwave oven 200. In the fan assembly 10 of the present application, the air deflector 13 is disposed on the side of the fan blade structure 11 facing the top 201 of the microwave oven 200. The air deflector 13 is in the shape of an arc and partially surrounds the fan blade structure 11. The air deflector 13 plays a role in collecting cold air which easily escapes, effectively reduces the diffusion angle of the cold air, and increases the air inlet flow in the direction of the heating component. And increase wind pressure and wind speed, reduce the inside flow field backward flow volume of heating element spare, improve the radiating efficiency of heating element spare. In addition, the air deflector 13 only needs to be arranged on the bracket 120, so that the number of fan blades and additional parts are not increased, the rotating speed of the motor does not need to be increased, and the working power of the fan assembly 10 is not sacrificed. The fan assembly 10 is compact and meets installation space requirements.
In some embodiments, as shown in FIG. 2, FIG. 2 is a front view schematic diagram of the fan assembly shown in FIG. 1. The arc span of the air deflector 13 is 60-180 degrees. Such as 60 °, 77 °, 82 °, 90 °, 103 °, 115 °, 120 °, 135 °, 166 °, 175 °, 180 °, or the like, without limitation. Within this range, the arc span of the air deflector 13 is not too small, and an effective flow collection effect can be achieved. The air deflector 13 can effectively prevent the air discharged from the fan blade structure 11 from escaping from the top 201 and the two wings. In addition, in the range, the arc span of the air deflector 13 is not too large, and the requirement of installation space is fully considered. The fan assembly 10 is compact and compatible with high voltage capacitors. Meanwhile, the range of the air deflector 13 is not too large, so that the cold air can be prevented from escaping from the top 201 due to the fact that the space below the fan blade structure 11 is surrounded.
It should be noted that the air guiding plate 13 has a first portion 131 and a second portion 132. The first portion 131 and the second portion 132 are connected. Wherein the first portion 131 is located at one side of a vertical plane of the central axis of the fan blade structure 11. Second portion 132 is located on the other side of the vertical plane in which the central axis of fan blade structure 11 is located. In order to ensure that the air deflector 13 effectively collects the cool air escaping from the top 201 of the fan blade structure 11, the arc span a of the first portion 131 is greater than or equal to 30 °. The arc span b of the second portion 132 is 30 ° or more. The air deflector 13 can play an effective flow collecting role in dissipating cold air at the top 201 of the fan blade structure 11, and effectively reduce the cold air diffusion angle. The arc spans of the first and second portions 131, 132 may be the same or different. When one part is limited by the structure and the arc span is limited, the arc span angle of the other part can be increased in the range, thereby increasing the flexibility of the structure design.
In some embodiments, the clearance c between the air deflector 13 and the blade structure 11 is 2.5mm to 5 mm. For example 2.5mm, 2.7mm, 3mm, 3.1mm, 3.3mm, 3.5mm, 4mm, 4.3mm or 5mm etc. In this range, the structure between the air deflector 13 and the fan blade structure 11 is not too large, so as to ensure the air collecting effect of the air deflector 13 on the air outlet of the fan blade structure 11. In this range, the structure between the air guide plate 13 and the fan blade structure 11 is not too small, so that the error caused by the installation of the fan blade structure 11 can be accommodated, and the collision between the fan blade structure 11 and the air guide plate 13 caused by the vibration of the fan blade structure 11 in the rotation process can be avoided. Meanwhile, the fan blade structure 11 may expand and deform at a high temperature, and the clearance between the air deflector 13 and the fan blade structure 11 can prevent the expanded fan blade structure 11 from interfering with the air deflector 13.
In some embodiments, as shown in FIG. 3, FIG. 3 is a side view schematic of the fan assembly shown in FIG. 1. In the extending direction of the central axis of the blade structure 11, the overlapping length d of the air guiding plate 13 and the blade structure 11 is greater than 1/4 of the length of the blade structure 11, and the overlapping length d of the air guiding plate 13 and the blade structure 11 is less than 1/2 of the length of the blade structure 11. Thereby ensuring the flow collecting effect of the air deflector 13 on the fan blade structure 11 and not occupying too large volume. The overlapping length d of the air deflector 13 and the fan blade structure 11 in the extending direction of the central axis of the fan blade structure 11 is within the above range, the escape angle of cold air at the air outlet 101 of the fan blade structure 11 is small, the intake flow in the direction of the heating component is large, the air pressure and the air speed are also large, and the heat dissipation efficiency of the heating component is effectively improved.
In order to further reduce the diffusion angle of the cold air at the air outlet 101 of the fan blade structure 11, at the side of the air outlet 101 of the fan assembly 10, the side of the air deflector 13 is flush with the end surface of the fan blade structure 11. Therefore, the air deflector 13 can effectively reduce the diffusion angle of the cold air at the air outlet 101 of the fan blade structure 11, and the air deflector 13 does not occupy too much space outwards in the extending direction of the central shaft of the fan blade structure 11, so that the structure of the fan assembly 10 is more compact.
In other embodiments, the side of the air guiding plate 13 protrudes out of the end surface of the fan blade structure 11, so that the air guiding plate 13 can effectively reduce the diffusion angle of the cold air at the air outlet 101 of the fan blade structure 11. It should be noted that the length of the side edge of the air guiding plate 13 protruding from the end face of the fan blade structure 11 is within a reasonable range allowed by the structure, so that interference with other components is avoided, and the diffusion angle of the cold air at the air outlet 101 of the fan blade structure 11 is effectively reduced.
In other embodiments, a horizontal plane on which the central axis of the fan blade structure 11 is located is taken as a first plane. The orthographic projection of the air deflector 13 on the first plane is an arc shape protruding towards the air outlet 101 side of the fan blade structure 11, and the most protruding point of the arc shape facing the air outlet 101 side is located on the central axis of the fan blade structure 11. Therefore, the air deflector 13 can effectively prevent the air outlet of the fan blade structure 11 from escaping from the top 201 area which is easy to escape, the air deflector 13 has a flow collecting effect on the easy escape of cold air, the cold air diffusion angle is effectively reduced, and the air inlet flow in the direction of the heating component is increased.
In some embodiments, as shown in fig. 4, fig. 4 is a schematic perspective view of an application scenario of the fan assembly of the present application. The fan assembly 10 also includes a fixing plate 110. The fixing plate 110 is for being disposed in the microwave oven 200. The fixing plate 110 is provided with a pre-fixing hole 111. Bracket 120 is used to secure blade structure 11. The bracket 120 is correspondingly provided with a hanging part 121 facing the fixing plate 110. The bottom 202 of the hanging portion 121 is provided with a slot 122 that can be hung on the pre-fixing hole 111.
As described above, the fan blade structure 11 is fixed on the bracket 120, and the fixing plate 110 is disposed in the microwave oven 200. The fixing of the fan blade structure 11 in the microwave oven 200 body can be realized by fixing the bracket 120 and the fixing plate 110 to each other. It is understood that the fixing plate 110 may be integrally formed with the microwave oven body. Since the bracket 120 is provided with the hanging portion 121, the fixing plate 110 is correspondingly provided with the pre-fixing hole 111. The hanging part 121 is aligned and placed in the pre-fixing hole 111, and the bracket 120 is loosened. Under the action of gravity, the engaging groove 122 of the hanging portion 121 is engaged with the bottom end of the pre-fixing hole 111, so as to pre-fix the bracket 120 on the fixing plate 110.
Since the hanging portion 121 is placed in the pre-fixing hole 111, the bracket 120 can be hung on the fixing plate 110 under the action of gravity, and the fan assembly 10 of the present application does not need to be obliquely inserted and pressed. The fan assembly 10 requires a small operating space for installation and is compatible with a compact product layout. Moreover, the fixing mode has low requirement on assembly fit tolerance and is beneficial to production and assembly. In addition, since the bracket 120 and the fixing plate 110 in the fan assembly 10 of the present application are installed without being obliquely inserted and pressed, the installation efficiency is high. And the installation process can be realized by adopting automatic equipment, and the production efficiency is effectively improved by automatic production.
In order to ensure the stable fixation of the bracket 120 and the fixing plate 110, the fixing plate 110 is provided with a first screw hole 112. Bracket 120 is provided with second screw hole 124 provided corresponding to first screw hole 112. The bracket 120 and the fixing plate 110 are further stably fixed by inserting screws through the first screw hole 112 and the second screw hole 124. After the hanging part 121 of the bracket 120 is hung on the fixing plate 110, the bracket 120 does not need to be limited by manpower and additional auxiliary equipment in the screw fastening process between the bracket 120 and the fixing plate 110. And the screw fastening can be realized through automatic equipment, and the installation efficiency is improved. Thus, the fan assembly 10 of the present application can achieve pre-installation automation, self-limiting, and screw fastening automation, i.e., achieve full-automatic installation and fixation of the fan blade structure 11 in the microwave oven body.
Wherein, the first screw hole 112 may be provided with one, two, three or more. Correspondingly, the second screw hole 124 may be provided with one, two, three or more. The bracket 120 and the fixing plate 110 are fixed by one, two, three or more screws.
Further, the second screw holes 124 have a guide surface (not shown) on the side facing away from the fixing plate 110. The guide surface facilitates entry of the screw into the second screw hole 124. The guide surface is also favorable for automatic equipment to realize screw fastening, and improves installation efficiency.
In some embodiments, in order to facilitate hanging the hanging part 121 in the pre-fixing hole 111, when the center of the hanging part 121 coincides with the center of the pre-fixing hole 111, an orthogonal projection of the hanging part 121 on a plane where a surface of the fixing plate 110 facing the hanging part 121 is located in the pre-fixing hole 111. When the bracket 120 and the fixing plate 110 are preassembled, the hanging portion 121 can be directly inserted into the pre-fixing hole 111 by blind insertion only by aligning the center of the hanging portion 121 with the center of the pre-fixing hole 111. After the bracket 120 is loosened, the engaging slot 122 of the hanging portion 121 is engaged with the bottom end of the pre-fixing hole 111 under the action of gravity, so as to pre-fix the bracket 120 on the fixing plate 110.
Specifically, when the center of the hanging part 121 coincides with the center of the pre-fixing hole 111, the distance between the edge of the orthographic projection of the hanging part 121 on the plane where the surface of the fixing plate 110 facing the hanging part 121 is located and the edge of the pre-fixing hole 111 is 0.3-0.8 mm. For example 0.3mm, 0.5mm or 0.8mm etc. Because a certain gap is formed between the edge of the orthographic projection of the hanging part 121 on the plane of the surface of the fixing plate 110 facing the hanging part 121 and the edge of the pre-fixing hole 111, the requirement of installation fit tolerance can be reduced, and the installation efficiency of the bracket 120 and the fixing plate 110 can be improved. In the above range, the gap between the edge of the orthographic projection of the hanging part 121 on the plane where the surface of the fixing plate 110 facing the hanging part 121 is located and the edge of the pre-fixing hole 111 is not too large, and the hanging part 121 is not easily detached from the pre-fixing hole 111. And also plays a role in limiting the subsequent screw fastening process of the bracket 120 and the fixing plate 110.
In some embodiments, as shown in fig. 5, fig. 5 is an enlarged schematic view of portion a of fig. 4. The hanging portion 121 is provided with a step surface 123 facing the holder 120. The step surface 123 and the surface of the bracket 120 are enclosed to form a clamping groove 122. After the hanging part 121 is inserted into the pre-fixing hole 111, the bracket 120 is released. Under the action of gravity, the engaging groove 122 of the hanging portion 121 is engaged with the bottom end of the pre-fixing hole 111, so as to pre-fix the bracket 120 on the fixing plate 110. Because the stepped surface 123 and the surface of the bracket 120 are enclosed to form the clamping groove 122, the stepped surface 123 and the surface of the bracket 120 close to one side of the fixing plate 110 play a role in limiting the matching of the hanging part 121 and the pre-fixing hole 111, and the hanging part 121 is prevented from being separated from the pre-fixing hole 111. Of course, when there are a plurality of hanging portions 121, a step surface 123 of at least a part of the hanging portions 121 facing the holder 120 needs to be surrounded with the surface of the holder 120 to form the engaging groove 122. The remaining hanging portions 121 may be formed with a stepped surface 123 toward the side of the bracket 120 only at the bottom to hang on the pre-fixing holes 111. At this time, the bracket 120 may also be pre-fixed to the fixing plate 110.
In order to facilitate the insertion of the hanging portion 121 into the pre-fixing hole 111, the hanging portion 121 is provided with a guide surface 125 toward the end of the fixing plate 110 side. When the guiding surface 125 of the hanging portion 121 contacts the edge of the pre-fixing hole 111, the guiding surface 125 can guide the hanging portion 121 to be inserted into the pre-fixing hole 111, thereby facilitating the alignment and installation of the hanging portion 121 and the pre-fixing hole 111. Specifically, the guide surface 125 may be located at a side end of the hanging portion 121 facing the fixing plate 110 and disposed downward. Alternatively, the guide surface 125 may be located at the end of the hanging portion 121 facing the fixed plate 110 and facing upward.
Further, in order to avoid the problem of play of the bracket 120 when the bracket 120 and the fixing plate 110 are fastened by screws, the number of the hanging portions 121 is 2 or more. In the present embodiment, four hanging portions 121 are provided, and the four hanging portions 121 are arranged in a quadrilateral shape. The four hanging parts 121 are hung on the corresponding four pre-fixing holes 111, and the bracket 120 is stably hung on the fixing plate 110. The play problem is also less likely to occur when the bracket 120 and the fixing plate 110 are further fastened by screws. Of course, in other embodiments, the hanging portion 121 may be provided with two, three, five or more. The fixing plate 110 is provided with a corresponding number of pre-fixing holes 111. Only by ensuring the matching of the hanging part 121 and the pre-fixing hole 111, the bracket 120 and the fixing plate 110 are not easy to move when the screws are fastened.
Further, as shown in fig. 6, fig. 6 is a schematic front structural view of a bracket of an embodiment of the fan assembly of the present application. Among the straight lines of the four sides of the quadrangle formed by the four hanging portions 121, at least one straight line intersects with the other straight lines. Thus, each hanging portion 121 can only correspond to one pre-fixing hole 111, and the bracket 120 can only be mounted on the fixing plate 110 from one direction. The arrangement of the four hanging portions 121 plays a fool-proof role. For the convenience of understanding, it can be further understood that the quadrangle formed by the four hanging portions 121 is a non-rotationally symmetrical figure, or at least one pair of opposite sides in the quadrangle formed by the four hanging portions 121 are different in length. At this time, the holder 120 can be mounted to the fixing plate 110 only from a single direction regardless of rotation.
Referring to fig. 7, another embodiment of the present application provides a microwave oven 200 including a body and a fan assembly 10. The fan assembly 10 is disposed in the main body, and the fan assembly 10 is the fan assembly 10 in any of the above embodiments. Wherein, the microwave oven 200 has a top part 201 and a bottom part 202 which are oppositely arranged, and the bottom part 202 of the microwave oven 200 is used for being placed on a workbench. Fan assembly 10 includes a support frame 120, a blade structure 11, and an air deflector 13. Fan blade structure 11 is disposed on support 120. The air deflector 13 is disposed on the bracket 120, and the air deflector 13 is located on a side of the fan blade structure 11 facing the top 201 of the microwave oven 200, and the air deflector 13 partially surrounds the fan blade structure 11 in an arc shape.
In the structure of microwave oven 200, a heating component (e.g., a frequency converter, a transformer, a magnetron, etc.) is generally disposed on the side of air outlet 101 of fan blade structure 11. Therefore, wind resistance exists at the air outlet 101 of the fan blade structure 11, the wind blown out by the fan blade structure 11 can be radially diffused, and the flow dissipation occurring at the top 201 and the left and right wings of the fan blade structure 11 facing the microwave oven 200 is particularly obvious. The utility model provides a fan assembly 10 is used for setting up aviation baffle 13 towards top 201 one side of microwave oven 200 through at flabellum structure 11, and aviation baffle 13 is circular-arc part and surrounds flabellum structure 11, aviation baffle 13 plays the mass flow effect to the easy loss of cold wind, effectively reduce cold wind diffusion angle, the intake flow of increase heating components and parts direction, and increase wind pressure and wind speed, reduce the inside flow field backward flow of heating components and parts, improve heating components and parts's radiating efficiency. In addition, the air deflector 13 only needs to be arranged on the bracket 120, the number of fan blades and additional parts are not increased, the rotating speed of the motor does not need to be increased, the working power of the fan assembly 10 is not sacrificed, the structure of the fan assembly 10 is compact, and the requirement of installation space is fully considered.
