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 existing method for pressing and fixing the bracket of the fan in the microwave oven after obliquely inserting the bracket or directly pressing and fixing the bracket in the microwave oven in the normal direction needs alignment and pressing steps, requires more operation space and cannot be compatible with the layout of compact products. And the bracket needs to be pre-fixed in the microwave oven by pressing, so that the requirement on assembly fit tolerance is high. The existing methods all have the problems of low installation efficiency and inconvenient realization of automatic installation.

Referring to fig. 1 and 2, fig. 1 is a schematic perspective view of an embodiment of a fixing assembly of the present application; fig. 2 is an enlarged schematic view of a portion a of fig. 1.

An embodiment of the present application provides a fixing assembly 100, as shown in fig. 1, the fixing assembly 100 is used to fix a fan in a body of a microwave oven. Wherein the fixing assembly 100 includes a fixing plate 110 and a bracket 120. The fixing plate 110 is disposed on the microwave oven body. The fixing plate 110 is provided with a pre-fixing hole 111. The bracket 120 is used to fix the fan. The bracket 120 is provided with a hanging part 121 facing the fixing plate 110. The bottom of the hanging part 121 is provided with a slot 122 capable of hanging on the pre-fixing hole 111.

With the above structure, the fan is fixed on the bracket 120. The fixing plate 110 is disposed in the microwave oven body. The fixing of the fan in the microwave oven body can be achieved 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. Because the hanging part 121 is arranged on the bracket 120, the fixing plate 110 is correspondingly provided with the pre-fixing hole 111, the hanging part 121 is only required to be aligned and placed in the pre-fixing hole 111, the bracket 120 is loosened, and the clamping groove 122 of the hanging part 121 is clamped at the bottom end of the pre-fixing hole 111 under the action of gravity, so that the pre-fixing of the bracket 120 on the fixing plate 110 is realized.

After the hanging part 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, the fixing assembly 100 of the present application does not need to be obliquely inserted and pressed, the operation space required for installing the fixing assembly 100 is small, and the layout of compact products can be compatible. 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 fixing assembly 100 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 using an automatic device, and the production efficiency is effectively improved by automatic production.

In order to ensure stable fixation of the bracket 120 and the fixing plate 110, as shown in fig. 1, the fixing plate 110 is provided with a first screw hole 112. Bracket 120 is provided with second screw hole 124 provided to correspond 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 screw fastening process between the bracket 120 and the fixing plate 110 does not need to limit the fan bracket 120 by manpower and additional auxiliary equipment, and the screw fastening can be realized through automatic equipment, so that the installation efficiency is improved. Thus, the fixing assembly 100 of the present application can realize pre-installation automation, self-limiting, and screw fastening automation, i.e., realize full-automatic installation and fixation of the fan 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, as shown in fig. 2, 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 realizing screw fastening of automatic equipment, and the installation efficiency is improved.

In some embodiments, as shown in fig. 1, in order to facilitate hanging the hanging portion 121 into the predetermined fixing hole 111, when the center of the hanging portion 121 coincides with the center of the predetermined fixing hole 111, an orthographic projection of the hanging portion 121 on a plane where a surface of the fixing plate 110 facing the hanging portion 121 is located in the predetermined 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 locking slot 122 of the hanging part 121 is locked at the bottom end of the pre-fixing hole 111 under the action of gravity, so that the bracket 120 is pre-fixed 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 the edge of the orthogonal projection of the hanging part 121 on the plane of the surface of the fixing plate 110 facing the hanging part 121 has a certain gap with 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, the hanging part 121 is not easy to fall off from the pre-fixing hole 111, and the screw fastening process of the subsequent bracket 120 and the fixing plate 110 is limited.

Further, as shown in fig. 1, the number of the hanging portions 121 is 2 or more in order to avoid a problem of play of the bracket 120 when the bracket 120 and the fixing plate 110 are fastened by screws. 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 portions 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 unlikely 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. 3, fig. 3 is a schematic front structural view of a bracket of an embodiment of the fixing assembly of the present application. At least one of the straight lines on which the four sides of the quadrangle formed by the four hanging portions 121 are located intersects with the other straight lines. Thus, each hanging portion 121 can only correspond to one pre-positioning hole 111, and the bracket 120 can only be installed 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.

In some embodiments, as shown in fig. 2, the hanging portion 121 is provided with a step surface 123 toward the side of the bracket 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, as shown in fig. 2, 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, so as to facilitate the alignment and installation of the hanging portion 121 and the pre-fixing hole 111. Specifically, the guide surface 125 may be located at an end of the hanging portion 121 toward the fixing plate 110 and be disposed downward; alternatively, the guide surface 125 may be located at an end of the hanging portion 121 facing the fixing plate 110 and facing upward.

Referring to fig. 4 to 7, fig. 4 is a schematic partial perspective view of a microwave oven according to an embodiment of the present application; FIG. 5 is a schematic perspective view of a fan blade structure, a bracket and a wind deflector according to an embodiment of the present invention; FIG. 6 is a schematic front view of a fan blade structure, a bracket and a wind deflector according to an embodiment of the present invention; fig. 7 is a side view of a fan blade structure, a bracket and a wind deflector according to an embodiment of the present invention.

The present application provides a microwave oven 200, the microwave oven 200 including a microwave oven body (only a rear plate 210 is shown in the drawings) and a fan. In some embodiments, the microwave oven body includes a rear plate 210, and the fixing plate 110 is the rear plate 210. The fan is fixed to the rear plate 210 of the microwave oven body through the bracket 120.

The fan is fixed in the microwave oven body by the fixing assembly 100 of any of the above embodiments. The fixing assembly 100 includes a fixing plate 110 and a bracket 120. The fixing plate 110 is disposed on the microwave oven body. The fixing plate 110 is provided with a pre-fixing hole 111. The bracket 120 is used to fix the fan. The bracket 120 is correspondingly provided with a hanging portion 121 on one side facing the fixing plate 110, and a locking groove 122 capable of being hung on the pre-fixing hole 111 is formed at the bottom of the hanging portion 121.

As can be seen from the above structure, the fan is fixed to the bracket 120. The fixing plate 110 is disposed in the microwave oven body. The fixing of the fan in the microwave oven body can be achieved by fixing the bracket 120 and the fixing plate 110 to each other. Because the hanging part 121 is arranged on the bracket 120, the fixing plate 110 is correspondingly provided with the pre-fixing hole 111, the hanging part 121 is only required to be aligned to be placed in the pre-fixing hole 111, the bracket 120 is loosened, and under the action of gravity, the clamping groove 122 of the hanging part 121 is clamped at the bottom end of the pre-fixing hole 111, so that the pre-fixing of the bracket 120 on the fixing plate 110 can be realized.

After the hanging part 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 fixing assembly 100 of the present application does not need to be obliquely inserted and pressed. The fixing assembly 100 requires a small operation space for installation and is compatible with the layout of a compact product. Moreover, the fixing mode has low requirement on assembly fit tolerance and is beneficial to production and assembly. In addition, because the bracket 120 and the fixing plate 110 in the fixing assembly 100 of the present application are installed without being obliquely inserted and pressed, the installation efficiency is high, the installation process can be realized by using an automatic device, and the production efficiency is effectively improved by automatic production.

In some embodiments, as shown in fig. 4 and 5, the microwave oven 200 has a top 201 and a bottom 202 disposed opposite each other. Wherein the bottom 202 of the microwave oven 200 is used for being placed on a workbench. The microwave oven 200 further includes a wind deflector 13. The fan comprises a blade structure 11. Fan blade structure 11 is disposed on support 120. The air deflector 13 is disposed on the bracket 120. The air deflector 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 from the fan blade structure 11 can be radially diffused. 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 microwave oven 200 of the present application, the air guide plate 13 is disposed on the fan blade structure 11 toward the top 201 side 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, 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 is not sacrificed, and the fan blade structure 11 and the air deflector 13 are compact in structure, so that the requirement of installation space is fully considered.

In some embodiments, as shown in FIG. 6, the arc span of the air deflection plates 13 is 60-180. Such as 60 °, 90 °, 120 °, 180 °, etc., 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-guiding plate 13 can effectively prevent the air outlet of the fan blade structure 11 from escaping from the top portion 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 blade structure 11 and the air deflector 13 are compact in structure and compatible with a high-voltage capacitor. Meanwhile, the range of the air deflector 13 is not too large, so that 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 deflector 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 where the central axis of the fan blade structure 11 is located. 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 performs an effective flow collection function on cold air dissipation at the top 201 of the blade structure 11, the arc span a of the first portion 131 is greater than or equal to 30 °, and the arc span b of the second portion 132 is greater than or equal to 30 °. Therefore, the air deflector 13 can effectively collect the cold air escaping from 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.

In some embodiments, as shown in FIG. 6, the clearance c between the air deflector 13 and the fan 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 deflector 13 and the fan blade structure 11 is not too small, so that the error of the fan blade structure 11 during installation can be accommodated, and the collision between the fan blade structure 11 and the air deflector 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 generate a certain expansion deformation under the high temperature, and the clearance between the air guide plate 13 and the fan blade structure 11 can avoid the interference between the expanded fan blade structure 11 and the air guide plate 13.

In some embodiments, as shown in fig. 7, 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, the side edge of the air deflector 13 is flush with the end surface of the fan blade structure 11 at the side of the air outlet 101 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 air deflector 13 and the structure of the fan blade structure 11 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-shaped 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-shaped 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 the 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. Thereby aviation baffle 13 can effectively prevent the regional loss of top 201 of flabellum structure 11's air-out from easy loss, and aviation baffle 13 plays the mass flow effect to the easy loss of cold wind, effectively reduces the cold wind diffusion angle, increases the air inlet flow of the components and parts direction that generates heat.
