This application discloses a combination stove, as shown in Figures 1 to 4. In some embodiments, the combination stove includes a cover plate 2000, a connector 4000 and an air inlet assembly.

Since the combination stove will produce oil fume during use, the combination stove needs to extract the oil fume, and an air inlet assembly will be installed on the air inlet path of the combination stove. The air inlet assembly is used to guide and filter the air. It can be seen that whether the positioning of the air inlet assembly is accurate or not has a great impact on the flow of air. Therefore, in this embodiment, by arranging the connector 4000 on the cover 2000, the positioning between the connector 4000 and the cover 2000 is easier. Supporting the air inlet assembly on the connector 4000 in this way will make the matching between the air inlet assembly and the opening 2100 of the cover 2000 more accurate, preventing a large gap from appearing relative to the opening 2100 after the air inlet assembly is assembled, thereby preventing air leakage and result in an unsightly overall appearance.

Specifically, a combination stove is a combination electrical appliance that has the functions of a stove and a hood. The stove function can realize the cooking of ingredients with open flame or non-open flame. For example, cooking areas are set up on the left and right sides of the combination stove. The cooking areas are equipped with electromagnetic heating devices correspondingly, and burners that use flammable gas can also be set up for combustion. The hood function can extract the fumes generated during the cooking process of ingredients to avoid air pollution in the kitchen space.

As shown in Figures 1 to 4, generally speaking, a combination stove includes a body 1000, a cover 2000 and a fan 3000.

The body 1000 plays the role of a carrying frame in the combination stove, and is used to install various components and maintain the overall shape of the combination stove.

The cover 2000 is installed on the body 1000 to form the top surface of the combination stove. When the combination stove is installed in the cabinet, the cover 2000 is exposed. The cover 2000 is generally flat and can be made of glass, for example. The cover 2000 is provided with an opening 2100 that runs through the upper and lower surfaces of the cover 2000. The left side of the opening 2100 is the left cooking area 2210, and the right side of the opening 2100 is the right cooking area 2220. The body 1000 An electromagnetic heating device is provided in the interior corresponding to the left cooking zone 2210, and an electromagnetic heating device is also provided in the fuselage 1000 corresponding to the right cooking zone 2220 (of course, a burner using combustible gas can also be provided).

As shown in Figures 21 to 23, the fan 3000 includes a volute 3100, an impeller 3400 and a motor. The volute 3100 includes a lower volute 3120 and an upper volute 3110. The motor is installed on the lower volute 3120. The impeller 3400 is a centrifugal wind wheel and is installed on the lower volute 3120 and is connected to the motor drive. The upper volute 3110 and the lower volute are 3120 is connected to cover the impeller 3400. An air duct 3500 is formed between the upper volute 3110 and the lower volute 3120. The impeller 3400 is located in the air duct 3500. The upper volute 3110 is provided with an air inlet 3111 connected with the air duct 3500. An air outlet 3121 connected to the air duct 3500 is formed between the shell 3110 and the lower volute 3120. The fan 3000 is fixed to the fuselage 1000 through the upper volute 3110.

When the motor in the fan 3000 works to drive the impeller 3400 to rotate, a negative pressure will be formed. Under the action of the pressure, the outside air will enter the fuselage 1000 from the opening 2100 of the cover 2000 and then enter the air duct 3500 through the air inlet 3111. , and then discharged through the air outlet 3121. The path that the air flows from the opening 2100 of the cover 2000 to the air inlet 3111 of the fan 3000 can be regarded as an air inlet path.

As shown in Figures 18 and 19, a mounting piece 2300 is provided on the lower surface of the cover plate 2000. The mounting piece 2300 is provided on four sides of the cover plate 2000. The mounting piece 2300 includes a first connecting edge 2310 and a second connecting edge. 2320. The first connecting edge 2310 is set close to the edge of the cover plate 2000, and is connected to the lower surface of the cover plate 2000 by bonding. For example, glass glue is used to bond the first connecting edge 2310 to the lower surface of the cover plate 2000. connected, and then connected to the fuselage 1000 through the second connecting edge 2320.

The fuselage 1000 includes a base plate 1100 and side plates 1200. The base plate 1100 is roughly rectangular. Side plates 1200 are provided on four sides of the base plate 1100. The base plate 1100 and the side plates 1200 are formed by bending a single piece of sheet metal. This can greatly improve the structural strength of the fuselage 1000. The second connection edge 2320 extends from the first connection edge 2310 toward the fuselage 1000, and the second connection edge 2320 has a certain inclination relative to the cover plate 2000 (defining a plane perpendicular to the cover plate 2000, and the plane and the second connection edge 2320 is defined as the inclination), and the side plate 1200 relative to the fuselage 1000 is inclined toward the inside of the fuselage 1000, for example, inclined at 2°, 5°, 8°, 10°, etc., so that the four second connections The range enclosed by the side 2320 is smaller than the range enclosed by the four side plates 1200 . When the cover 2000 is installed on the fuselage 1000, during the movement of the cover 2000, the top of the side panel 1200 of the fuselage 1000 will touch the area between the top and the bottom of the second connecting edge 2320. The two connecting edges 2320 are arranged in an inclined manner, which can better guide the movement of the cover 2000, thereby reducing the installation difficulty of the cover 2000 and improving the installation efficiency of the cover 2000.

After the cover plate 2000 is installed at a predetermined position, fasteners (such as screws, bolts, etc.) are used to penetrate the side plate 1200 and the second connecting edge 2320 to fasten the fuselage 1000 and the cover plate 2000 . It can be understood that the second connecting edge 2320 and the side plate 1200 need to have corresponding screw holes in advance, so that fasteners can be used for penetration and fixation after installation.

As shown in Figures 18 and 19, the first connecting edge 2310 and the second connecting edge 2320 are integrally formed sheet metal structures, which are formed by bending, and the second connecting edge 2320 starts from the inside of the first connecting edge 2310. The edge extends downward obliquely, and the inner side of the first connecting edge 2310 is the side closer to the inside of the fuselage 1000 . This can prevent the cover 2000 from being deformed or even damaged due to pressure.

Specifically, when the mobile cover 2000 is installed on the fuselage 1000, since the second connecting edge 2320 is inclined, when the cover 2000 is installed in place, the top of the side panel 1200 will be connected with the first connecting edge 2310 and the second connecting edge 2310. The intersection of the sides 2320 offsets each other, or offsets the first connecting edge 2310, that is, the side plate 1200 exerts force on the cover plate 2000 through the first connecting edge 2310. The setting of the first connecting edge 2310 increases the effect of the force. area, thereby preventing the cover 2000 from being damaged, especially when the cover 2000 is a glass cover 2000 .

If the second connecting edge 2320 extends obliquely inward from the outside of the first connecting edge 2310, then when the movable cover 2000 is installed at a predetermined position, the top of the side plate 1200 will abut the lower surface of the cover 2000. Since the side plate The contact area between the top of the side plate 1200 and the lower surface of the cover plate 2000 is small, so the force generated by the side plate 1200 on the cover plate 2000 will be relatively large, and the cover plate 2000 will be more easily deformed or even broken due to force.

When installing the fan 3000, the fuselage 1000 and the cover 2000, first place the fan 3000 at the installation station, then align the fuselage 1000 with the fan 3000 and place it on the fan 3000 as a whole, and then use fasteners to remove the screws from the fuselage 1000. The fuselage 1000 is penetrated inside, that is, the fasteners penetrate from the inner surface of the fuselage 1000 to the outer surface of the fuselage 1000 to be tightly connected with the fan 3000. Finally, the cover plate 2000 is installed on the fuselage 1000. In this way, there is no need to connect the body 1000 to the cover 2000 first and then to the fan 3000. Since the cover 2000 is heavy, this can reduce the difficulty of operation, avoid exposure of fasteners, and improve the aesthetics of the combination stove.

Specifically, as shown in FIG. 20 , the upper volute 3110 is provided with a convex ring 3200 surrounding the air inlet 3111 , and the fuselage 1000 is provided with a mounting hole 1300 . Specifically, the bottom plate 1100 of the fuselage 1000 is provided with a mounting hole 1300 . In this way, when installing the fuselage 1000 and the fan 3000, the mounting hole 1300 on the fuselage 1000 is aligned with the volute 3100 of the fan 3000, and the fuselage 1000 is moved until the flange 3200 is embedded in the mounting hole 1300, that is, the fuselage 1000 passes through the volute casing 3100. The mounting hole 1300 is set on the raised ring 3200. The matching of the raised ring 3200 and the mounting hole 1300 realizes the positioning of the fuselage 1000 and the fan 3000 during installation, so as to facilitate subsequent fasteners to pass through the fuselage 1000 and fix the volute 3100. , reduce the difficulty of operation.

The raised ring 3200 further has a closed annular structure, which can prevent air from leaking in the raised ring 3200, and the closed annular structure can also facilitate the user to align the mounting hole 1300.

The volute 3100 is provided with a guide tube 3300, which extends from the outside of the fuselage 1000 toward the inside of the fuselage 1000, and penetrates into the fuselage 1000, thus facilitating the routing of wires.

Generally speaking, as shown in Figures 20 to 23, a circuit board and various components need to be provided in the fuselage 1000 for electrical connection. Since the fan 3000 is installed outside the fuselage 1000, if the motor of the fan 3000 is connected to the fuselage 1000 When connecting the circuit board inside, it is easy to cause the wires to be exposed, so the guide tube 3300 is provided to solve the problem. Specifically, the guide tube 3300 may be formed by fastening two half-shells, one of which is integrally formed with the volute 3100, and the other half-shell is formed as a separate component for fastening with the half-shell on the volute 3100. The guide tube 3300 extends from the volute 3100 to the fuselage 1000, so that the guide tube 3300 can guide and hide the wires, and the wires connect the motor of the fan 3000 and the circuit board in the fuselage 1000 without being exposed.

In addition, the fuselage 1000 is provided with a through hole 1400 that penetrates the inner and outer surfaces of the fuselage 1000, and the guide tube 3300 is inserted into the through hole 1400, which not only hides the wires, but also plays a positioning role, that is, When the fuselage 1000 and the fan 3000 are installed, in addition to using the protruding ring 3200 and the mounting hole 1300 for matching, the guide tube 3300 also needs to be inserted into the through hole 1400, so as to position each other.

Generally speaking, since it is necessary to prevent foreign matter from entering the fuselage 1000 through the opening 2100 of the cover 2000, a grille 5000 needs to be provided at the opening 2100 to block foreign matter from the outside and guide the air at the same time. In addition, the cooking process will produce more oil mist particles and water vapor, so it is necessary to install a filter device 6000 on the air inlet path. The filter device 6000 plays the role of rough filtration. When the air passes through the filter device 6000, some oil mist particles It will adhere to the filter device 6000, and the water vapor will also condense on the filter device 6000 when it encounters the filter device 6000. The grille 5000 and the filter device 6000 are called air inlet components. It can be seen that the position matching between the air inlet components and the air inlet path will affect the air inlet effect.

It can be understood that the air inlet assembly is disposed in the opening 2100, that is, the air inlet assembly can substantially cover the opening 2100 when installed, thereby allowing air to pass through the air inlet assembly.

By arranging the connector 4000 in the cover 2000, the connector 4000 is exposed at the opening 2100, and the air inlet assembly is supported in the connector 4000 when it is installed in the opening 2100. In this way, it only needs to ensure that the connector 4000 is installed in the cover 2000. The position is accurate, and the positional relationship of the air inlet assembly is not affected by the fuselage 1000. When the air inlet assembly is located at the opening 2100 and supported on the connector 4000, the mutual matching between the air inlet assembly and the air inlet path can be ensured. It is not easy to form a gap between the air inlet assembly and the opening 2100, thereby avoiding air leakage.

If the connector 4000 is not provided on the cover 2000 but on the fuselage 1000, then when installing the cover 2000 and the fuselage 1000, it is necessary to ensure the precise positioning between the cover 2000 and the fuselage 1000 to avoid the connector The offset of 4000 relative to the opening 2100 of the cover plate 2000 results in a positional deviation in the installation of the air inlet assembly. It seems that this installation method greatly increases the manufacturing difficulty.

In addition, the air inlet assembly is supported on the connecting piece 4000. For example, the air inlet assembly directly supports the connecting piece 4000 by gravity, thus achieving a detachable connection between the air inlet assembly and the connecting piece 4000. The air inlet assembly is supported on the connector 4000 by gravity. When the air flows, the force exerted by the air on the air inlet assembly tightly presses the air inlet assembly against the connector 4000. The air inlet assembly will not shake when the air flows. And cause abnormal noise. The user holds the air inlet assembly and inserts it into the opening 2100 from the outside of the cover 2000. The air inlet assembly can be supported on the connector 4000 under the action of gravity. Similarly, during disassembly, the user can hold the air inlet assembly and pull it out from the opening 2100. It is so convenient for users to disassemble and assemble, which improves the user experience.

Furthermore, as shown in FIG. 4 , precisely because the air inlet assembly is provided in the opening 2100 in a supporting manner, the air inlet assembly can be completely embedded in the opening 2100 , that is, the upper surface of the air inlet assembly can be no higher than the cover plate. The upper surface of the cover 2000 is arranged to prevent the air inlet assembly from protruding from the cover 2000 in the height direction and thereby hindering the cleaning process. The upper surface of the air inlet assembly is not higher than the upper surface of the cover 2000. It can be that the upper surface of the air inlet assembly is flush with the upper surface of the cover 2000, or it can be that the upper surface of the air inlet assembly is slightly lower than the cover 2000. upper surface.

It can be understood that the connecting piece 4000 is exposed in the opening 2100. When the combination stove is installed in the cabinet, if you look down directly above the combination stove, you can see that part of the connecting piece 4000 appears in the range surrounded by the opening 2100. Inside.

As shown in FIG. 4 , in some embodiments, the connector 4000 is disposed on the lower surface of the cover 2000 , so that the connector 4000 can be hidden.

Specifically, the air inlet assembly is provided at the opening 2100 and needs to be positioned at the opening 2100 so as to be located on the air inlet path. The connector 4000 can be arranged in a variety of ways. For example, the connecting member 4000 is provided on the upper surface of the cover 2000, but this method may easily cause obstruction to the user. When the combination stove is installed in the cabinet, the cover 2000 is exposed on the cabinet and is within the user's field of vision. If the connector 4000 is provided on the upper surface of the cover 2000, the connector 4000 will protrude from the upper surface of the cover 2000 and be easily hidden. It is dirty and difficult to clean, and will also damage the aesthetics of the cover 2000.

It is also possible that the connecting piece 4000 is disposed in the side wall 2110 of the opening 2100, but this method is not easy to fix the connecting piece 4000, and the weight that the connecting piece 4000 can bear is not large. The connecting piece 4000 supports the air inlet assembly. It is easy to loosen, causing the air inlet component to fall off. In order to take into account factors such as cost, weight, design, etc., the thickness of the cover 2000 is generally not too thick. Therefore, if the connector 4000 is only provided in the side wall 2110 of the opening 2100, the side wall 2110 of the opening 2100 cannot provide enough The position of the connecting piece 4000 is fixed, and the fixing between the connecting piece 4000 and the side wall 2110 of the opening 2100 becomes difficult.

This embodiment solves the above problem by disposing the connecting member 4000 on the lower surface of the cover plate 2000 . The connector 4000 is disposed on the lower surface of the cover plate 2000 so as to be hidden and will not protrude from the upper surface of the cover plate 2000 and thus will not damage the aesthetics of the cover plate 2000 . In addition, since the lower surface of the cover plate 2000 can provide sufficient positions for the connector 4000 to be fixed, more connection methods can be used between the connector 4000 and the lower surface of the cover plate 2000. The fixing effect of the two is compared to that of the connector 4000. 4000 would be better if it is disposed on the side wall 2110 of the opening 2100. It is only necessary to ensure that when the connector 4000 is fixed on the lower surface of the cover 2000, part of the connector 4000 is exposed in the opening 2100. In this way, when the air inlet assembly is inserted into the opening 2100 from the outside of the cover 2000 and embedded in the fuselage 1000, The connector 4000 can support the air inlet assembly.

Specifically, as shown in FIGS. 5 to 11 , in some embodiments, the connector 4000 includes a second connector 4200 and a first connector 4100 . The first connector 4100 is fixed on the lower surface of the cover 2000 . The second connecting part 4200 is used to support the air inlet assembly.

For example, the connecting piece 4000 is made of plastic and is integrally injection molded, and has a first connecting part 4100 and a second connecting part 4200 formed therein. By molding the connector 4000 from plastic material, the connector 4000 has the advantages of light weight and high toughness. When the combination stove is installed in the cabinet, when viewed from top to bottom, the part hidden in the cover 2000 can be regarded as the first connecting part 4100, and the part exposed in the opening 2100 can be regarded as the second connecting part 4200.

The connector 4000 can be a separate component and is fixed on the lower surface of the cover 2000 through additional connection methods. There are various connection methods, for example, the first connection part 4100 and the lower surface of the cover 2000 are bonded. The connection can also be achieved by welding or screwing.

For example, the cover 2000 and the first connecting part 4100 are connected by adhesive, apply glass glue on the first connecting part 4100, and then move the connecting piece 4000 to the corresponding position of the cover 2000 until the first The connecting part 4100 and the lower surface of the cover plate 2000 are bonded and fixed. In this way, the connection between the connecting part 4000 and the cover plate 2000 is realized more quickly, and the installation efficiency is high.

For another example, the cover 2000 is made of metal, the connector 4000 is moved to a corresponding position on the cover 2000, and the first connecting portion 4100 of the connector 4000 is fixed to the lower surface of the cover 2000 by welding or welding.

As shown in Figures 7 and 8, in some embodiments, one of the first connection part 4100 and the cover 2000 is provided with a glue groove 4110, which can prevent glue from overflowing during gluing and improve the bonding strength. Spend.

For example, a glue groove 4110 is provided in the first connection part 4100. The glue groove 4110 provides a space for glue. When the first connection part 4100 and the cover plate 2000 are connected through glue, it is necessary to connect the first connection part 4100 and the cover plate. 2000 squeeze each other, and during the extrusion process, the glue will not easily overflow to the opening 2100. It can be understood that the glue tank 4110 is set at a certain distance from the opening 2100, such as 0.5 cm, 1 cm, 1.5 cm, etc.

The glue tank 4110 can also be set in the cover 2000, but generally speaking, the cover 2000 is made of glass or sheet metal. It is more difficult to set the glue tank 4110 directly on the cover 2000 than to set the glue tank 4110 on the connector 4000. will be larger, and when the connector 4000 is made of plastic material, the glue groove 4110 can be integrally formed, which is simpler and more convenient.

As shown in FIG. 5 , in some embodiments, one of the cover plate 2000 and the second connecting part 4200 is provided with a positioning part, and the other one cooperates with the positioning part.

For example, taking the positioning part provided on the second connection part 4200 as an example, the positioning part provided on the cover 2000 also has a similar principle, and the details will not be repeated. The second connection part 4200 is provided with a positioning part. When installing the connection part 4000 and the cover plate 2000, it is more convenient to move the connection part 4000 to install it on the cover plate 2000 due to the large size and weight of the cover plate 2000. . A positioning part is provided on the connector 4000, and the installation can be realized by aligning it with the corresponding part of the cover plate 2000 during mobile installation. This can improve the installation efficiency and avoid installation errors.

Further, as shown in FIG. 5 , in some embodiments, the second connecting part 4200 is provided with convex ribs 4210 , and the convex ribs 4210 constitute a positioning part provided on the second connecting part 4200 .

The second connecting part 4200 is exposed from the first connecting part 4100 toward the opening 2100 and is exposed in the opening 2100. The rib 4210 is provided on the second connecting part 4200 and extends along the axial direction of the opening 2100 (axial direction, that is, when the combination stove is installed on the cabinet. state, the axial direction extends along the up and down position), close to the side wall 2110 of the opening 2100, so that when the connecting piece 4000 and the cover plate 2000 are installed, the connecting piece 4000 moves toward the cover plate 2000, and the ribs 4210 are inserted into the opening. 2100 and is disposed close to the side wall 2110 of the opening 2100, thus achieving rapid positioning between the connector 4000 and the cover plate 2000.

It can be understood that the rib 4210 can be in close contact with the side wall 2110 of the opening 2100, or there can be a gap between the rib 4210 and the side wall 2110 of the opening 2100. By arranging the ribs 4210 on the second connecting portion 4200, the opening 2100 of the cover plate 2000 can cooperate with the cover plate 2000 to achieve positioning and installation, without the need to separately provide a positioning structure on the cover plate 2000, thereby reducing the overall cost. Structural complexity.

As shown in Figure 6, in some embodiments, the connecting member 4000 has a ring structure. For example, if the opening 2100 of the cover 2000 is approximately rectangular as a whole, then the connector 4000 also forms an approximately rectangular annular structure. The annular structure of the connector 4000 can better support the air inlet assembly. In this way, the glue groove 4110 provided at the connecting part 4100 also has an annular structure.

Of course, in some embodiments, the connecting member 4000 may not be an annular structure, but may include multiple connecting members 4000 arranged at intervals along the circumference of the opening 2100, so that the air inlet assembly can also be supported. Trust.

As shown in Figures 4, 9 and 10, in some embodiments, the air inlet assembly includes a grille 5000 and a filter device 6000, and the grille 5000 is disposed above the filter device 6000.

The grille 5000 is a structure used to prevent external foreign matter from entering the interior of the combination stove through the opening 2100, and also serves to guide air.

There are many ways to install the grille 5000 and the filter device 6000. For example, the filter device 6000 is supported on the second connection part 4200, and the grille 5000 is directly supported on the filter device 6000. In this way, the grille 5000 is indirectly supported on the second connection part 4200 through the filter device 6000.

Alternatively, the filter device 6000 is supported on the second connecting part 4200, while the grille 5000 is supported on the raised ribs 4210, and the grille 5000 is indirectly supported on the second connecting part 4200 through the raised ribs 4210.

It is also possible that the filter device 6000 is supported on the raised ribs 4210 and the grille 5000 is supported on the filter device 6000. The filter device 6000 and the grille 5000 are indirectly supported on the second connecting portion 4200 through the raised ribs 4210.

In addition, the filter device 6000 may be supported on the second connecting part 4200, and the grille 5000 may be supported on both the ribs 4210 and the filtering device 6000. In this way, the grille 5000 may also be supported on the second connecting part 4200 indirectly.

The grille 5000 is located above the filter device 6000. When taking it out, the user can first take out the grille 5000 and then the filter device 6000; when putting it back in, the user can first install the filter device 6000 into the opening 2100 and support it. At the second connecting part 4200, the grille 5000 is installed to the opening 2100 and supported on the second connecting part 4200. The upper surface of the grille 5000 is flush with the upper surface of the cover plate 2000 , or slightly lower than the upper surface of the cover plate 2000 .

In some embodiments, as shown in FIG. 12 , the grille 5000 includes a frame 5100 and grille bars 5200 .

The grille 5000 is an annular hollow structure, which mainly plays the role of fixing the grille bars 5200. When the grille 5000 is installed in the opening 2100, the frame 5100 is supported on the connector 4000 (the second connector 4200), so that the entire grille bar 5200 can be fixed. Grille 5000 is secured to opening 2100. The grille 5000 can adopt various shapes, such as rectangle, square, hexagon, circle, oval and other shapes. In this application, the frame 5100 is rectangular as an example for description. The grille bars 5200 are disposed on the frame 5100. For example, the grille bars 5200 are disposed on opposite sides of the frame 5100. The grille bars 5200 and the frame 5100 can be fixed to each other in a variety of ways. For example, the frame 5100 and the grille bars 5200 are integrated. For example, the grille bars 5200 are connected to the frame 5100 by bonding, welding, screwing, snapping, etc.

Specifically, referring to Figure 12, the frame 5100 is approximately rectangular as a whole and has a first frame bar 5110, a second frame bar 5120, a third frame bar 5130 and a fourth frame bar 5140. The first frame bar 5110 and the third frame bar 5130 The second frame bar 5120 and the fourth frame bar 5140 are relatively disposed, between the first frame bar 5110 and the second frame bar 5120, between the second frame bar 5120 and the third frame bar 5130, the third frame bar 5130 There is an arc-like transition between the fourth frame bar 5140 and the fourth frame bar 5140 and the first frame bar 5110 .

The first frame strip 5110 and the third frame strip 5130 constitute the width direction side of the frame 5100, the second frame strip 5120 and the fourth frame strip 5140 constitute the length direction side of the frame 5100, and the size of the length direction of the frame 5100 is larger than Width dimension.

The grille bar 5200 is disposed between the first frame bar 5110 and the third frame bar 5130 , that is, the grille bar 5200 extends along the length direction of the frame 5100 . There are multiple grill bars 5200, which together with the frame 5100 form a grill structure, thereby preventing foreign matter from entering the inside of the combination stove, especially the fan 3000, along with the flow of air.

The bottom of the grill bar 5200 is provided with a tip 5230. It can be understood that the bottom here is based on the state where the grill 5000 is installed on the combination stove and the combination stove is installed on the cabinet. For example, as shown in Figures 1 to 3, when the grille 5000 is installed on the combination stove, the grille 5000, the filter device 6000 and the fan 3000 are provided from top to bottom, so that the bottom of the grille bar 5200 is close to the filter Device 6000 location.

As shown in FIGS. 14 and 15 , a tip 5230 is provided at the bottom of the grille bar 5200 , that is, the cross section suddenly becomes smaller or gradually becomes smaller. For example, define a plane that is perpendicular to the length direction of the grille bar 5200 and cut the grille bar 5200 to form a cross-section. Along the direction from the top to the bottom of the grille bar 5200 (from top to bottom), the cross-section is at The tip 5230 position becomes smaller.

Since the air contains a large amount of water vapor during the operation of the fan 3000, the water vapor will condense into water droplets when encountering the grille bars 5200. The water droplets will follow the surface of the grille bars 5200 under the action of airflow and gravity. As for the flow, when flowing to the tip 5230, the contact area between the water droplets and the tip 5230 becomes smaller, so that the water droplets easily drip to the filter device 6000 under the action of gravity and air flow, and are not easy to stick to the grille bars 5200. Water hanging phenomenon occurs.

As shown in Figures 14 and 15, in some embodiments, the grille bar 5200 is provided with a first side 5210 and a second side 5220. The first side 5210 and the second side 5220 are arranged oppositely, and the tip 5230 and the first side are arranged oppositely. One of the side surfaces 5210 and the second side surface 5220 is connected.

For example, the grille bar 5200 has a first side 5210 and a second side 5220, so that the grille bar 5200 has a vertical flat structure as a whole, which is conducive to guiding the air, and the air can flow through the first side 5210 when flowing. and second side 5220. The tip 5230 is connected to one of the sides, which can prevent water from hanging and reduce wind noise.

The description is based on the connection between the tip 5230 and the first side 5210. The tip 5230 and the first side 5210 are connected. It can be understood that the connection means that the tip 5230 is in the extension direction of the first side 5210 and between the first side 5210. Smooth transition, so that when the first side 5210 guides air, the air flow is not prone to turbulence between the first side 5210 and the tip 5230, thereby reducing wind noise. Especially, when the first side surface 5210 forms the windward surface, the occurrence of wind noise can be more effectively reduced.

In some embodiments, the first side 5210 is arranged at an angle, so that the first side 5210 constitutes the windward side.

For example, the tip 5230 is connected to the first side 5210, and a notch 5240 is formed between the tip 5230 and the second side 5220. The first side 5210 is arranged at an inclination, which can guide the air, thus forming a windward side. When the grille 5000 is installed on the combination stove, when looking down from directly above the combination stove, the first side 5210 can be observed but the second side 5220 cannot be observed. When the air flows, it will encounter the first side 5210 and flow along the first side 5210. Under the action of the first side 5210, the flow direction of the air changes along the inclination direction of the first side 5210. It is precisely because of the tip 5230 Being arranged in contact with the first side 5210, turbulence will not be formed between the tip 5230 and the first side 5210 when the air flows, thereby reducing wind noise. After the water vapor condenses on the first side 5210, it flows along the first side 5210. The extending direction of one side surface 5210 flows to the tip 5230 and drips.

A notch 5240 is formed between the tip 5230 and the second side 5220. The arrangement of the notch 5240 ensures that the cross-sectional area of the tip 5230 becomes smaller. Compared with the first side 5210, the air flow rate flowing through the second side 5220 is relatively small and the flow speed is relatively slow. Therefore, although the notch 5240 exists, it will not cause excessive wind noise.

Further, as shown in FIG. 15 , in some embodiments, the grille bar 5200 is provided with a chamfer 5221 , and the chamfer 5221 is provided on the top of the grille bar 5200 and close to the second side 5220 .

When the air flows, it will split into two airflows when it encounters the top of the grille bar 5200 , one of which flows along the first side 5210 and the other airflow flows along the second side 5220 . Since the first side 5210 is inclined, the flow of air can be better guided. The second side 5220 can be regarded as constituting the leeward side. In order to reduce the resistance of the second side 5220 to the air when the air first encounters the top of the grille bar 5200, the second side 5220 needs to be set to be inclined and aligned with the first side. The inclination direction of 5210 is opposite, forming a structural distribution similar to the "eight" figure, but this will cause too much air to pass through the second side 5220, and will have an adverse impact on the wind guide of the adjacent grille strips 5200. Wind noise will also increase accordingly. Therefore, in this embodiment, the top of the grille bar 5200 is provided with a chamfer 5221 close to the second side 5220. In this way, when the air encounters the top of the grille bar 5200, the airflow flowing toward the second side 5220 will not encounter the top of the grille bar 5200. Larger resistance, and can reduce the occurrence of turbulence, thereby reducing wind noise.

It can be understood that after the chamfer 5221 is provided, the second side 5220 can be arranged vertically or at a slight inclination. The slight inclination can be in the same direction as the inclination direction of the first side 5210 or in a different direction.

As shown in FIGS. 12 and 13 , in some embodiments, a convex portion 5250 is provided on the top of the grille bar 5200 . Through the arrangement of the convex portion 5250 , a printing effect can be achieved on the convex portion 5250 , thereby improving the overall quality of the grille 5000 . Aesthetics and differentiation of the Grille 5000.

For example, the top of the grille bar 5200 is provided with a convex portion 5250, that is, the top of the grille bar 5200 exhibits a concave and convex structure. The convex portions 5250 can be provided with one, two, three or more. When processing the grille 5000, the convex portions 5250 can be polished or printed to form a pattern on the convex portions 5250. The convex portions 5250 on each grille bar 5200 can cooperate to form an overall pattern, thereby improving the grille quality. 5000 overall aesthetics, and can provide more differentiated grille 5000. In addition, since the convex portion 5250 is in a convex state, it is ensured that the convex portion 5250 can be contacted at the same time without affecting the appearance of the grille bar 5200 during printing, which is more convenient and faster. When there are multiple grating bars 5200, the convex portions 5250 of adjacent grating bars 5200 are arranged in a staggered manner, which makes it easier to form patterns.

As shown in FIG. 14 and FIG. 16 , in some embodiments, the frame 5100 is surrounded by two air guide areas, namely the first air guide area 5410 and the second air guide area 5420 . The first air guide area 5410 is provided with The grille bars 5200 and the second air guide area 5420 are also provided with the grille bars 5200. The air guide direction of the first air guide area 5410 intersects with the air guide direction of the second air guide area 5420.

For example, the first air guide area 5410 is disposed close to the left cooking area 2210, and the first side 5210 of the grille bar 5200 of the first air guide area 5410 is disposed obliquely, that is, the first side 5210 is from the top of the grille bar 5200 to the grille. The bottom of the strip 5200 is inclined toward the second air guide area 5420, thereby guiding the air to flow toward the position where the second air guide area 5420 is located. It can be understood that the first side 5210 of the grille bar 5200 of the first air guide area 5410 extends from the bottom of the grille bar 5200 to the top of the grille bar 5200 toward the upper space corresponding to the left cooking area 2210 , so that when the fan 3000 is working, a negative pressure area can be formed in the upper space corresponding to the left cooking area 2210.

The second air guide area 5420 is arranged close to the right cooking area 2220, and the first side 5210 of the grille bar 5200 of the second air guide area 5420 is inclined, that is, the first side 5210 is from the top of the grille bar 5200 to the grille bar 5200 The bottom is inclined toward the first air guide area 5410, thereby guiding the air to flow toward the position where the first air guide area 5410 is located. It can be understood that the first side 5210 of the grille bar 5200 of the second air guide area 5420 extends from the bottom of the grille bar 5200 to the top of the grille bar 5200 toward the upper space corresponding to the right cooking area 2220 , so that when the fan 3000 is working, a negative pressure zone can be formed in the upper space corresponding to the cooking zone 2220 on the right side.

By setting the air guide directions of the first air guide area 5410 and the second air guide area 5420 to intersect, the oil mist and water formed by the left cooking area 2210 and the right cooking area 2220 can be better sucked. Vapors or other harmful substances. Moreover, the air guide direction of the first air guide area 5410 intersects with the air guide direction of the second air guide area 5420, thereby forming a function of converging the air flow, allowing the air flow to pass through the filtration device 6000 more effectively, and preventing the air flow from being disturbed and dispersed. Reducing the filtration effect can also avoid the problem of high wind noise caused by air flow disturbance.

As shown in FIGS. 16 and 17 , in some embodiments, the grille 5000 also includes a support member 5300 . The support member 5300 can be integrally formed with the frame 5100 , or can be connected to the frame 5100 through an additional connection method. The support 5300 is disposed on the grille 5000, thereby dividing the space enclosed by the grille 5000 into a first air guide area 5410 and a second air guide area 5420. The support 5300 includes a transverse frame 5310 and a vertical frame 5320. The transverse frame 5310 and the vertical frame 5320 are arranged perpendicularly to each other, and in the transverse direction, both sides of the transverse frame 5310 protrude from the vertical frame. 5320.

For example, when the grille 5000 is installed on the combination stove, when looking downward from directly above the combination stove, only the horizontal frame 5310 can be seen, and the horizontal frame 5310 blocks the vertical frame 5320. The horizontal frame bar 5310 protrudes from the vertical frame bar 5320, thereby forming an escape groove 5330 between the horizontal frame bar 5310 and the vertical frame bar 5320. Since oil mist is easy to adhere to the surface of the grille 5000, by arranging the horizontal frame 5310 and the vertical frame 5320, the user's hand can easily lift the support 5300 and press into the avoidance groove 5330, thereby increasing the distance between the support 5300 and the user. The friction between them makes it easier for the user to lift the grille 5000.

In some embodiments, the transverse slats 5310 are configured for mounting decorative elements, thereby improving the aesthetics of the grille 5000.

When the combination stove is installed in the cabinet, the cover 2000 is exposed from the cabinet and is within the user's field of vision, and the grille 5000 is provided at the opening 2100 of the cover 2000. In order to pursue diversification of appearance, decorative parts are installed on the grille 5000 in related technologies, but how to install the decorative parts becomes the key. In this embodiment, the support 5300 is disposed on the frame 5100 to divide the space surrounded by the frame 5100 into a first air guide area 5410 and a second air guide area 5420. The flow of air mainly occurs in the first air guide area 5410 and the second air guide area 5420. Second air guide area 5420, so the horizontal frame 5310 provided on the support 5300 will not have an excessive impact on the flow of air, thereby providing a basis for installing decorative parts on the horizontal frame 5310, so that both the grille 5000 and the grille 5000 can be The appearance is beautiful and differentiated, and it will not have an excessive impact on the flow of air.

As shown in FIGS. 12 and 15 , in some embodiments, the frame 5100 is provided with an inclined air guide surface 5101 to guide air, and the inclination of the first side 5210 is smaller than the inclination of the air guide surface 5101 .

Specifically, the frame 5100 has a first frame bar 5110, a second frame bar 5120, a third frame bar 5130 and a fourth frame bar 5140. The first frame bar 5110 and the third frame bar 5130 are arranged oppositely. The second frame bar 5120 and The fourth frame bars 5140 are arranged oppositely, and the first frame bar 5110, the second frame bar 5120, the third frame bar 5130 and the fourth frame bar 5140 all form air guide surfaces 5101. The air guide surface 5101 guides the air, that is, the air guide surface 5101 of the first frame bar 5110 guides the air flow toward the position of the third frame bar 5130, and the air guide surface 5101 of the third frame bar 5130 guides the air flow toward the position of the first frame bar 5110. For air flow, the air guide surface 5101 of the second frame bar 5120 guides the air flow toward the position of the fourth frame bar 5140, and the air guide surface 5101 of the fourth frame bar 5140 guides the air flow toward the position of the second frame bar 5120.

Slope is the deviation from the vertical plane. For example, the grille bar 5200 is disposed between the first frame bar 5110 and the third frame bar 5130 to define a vertical plane that is perpendicular to the grille 5000 and extends along the length direction of the grille bar 5200. The deflection degree of the air guide surface 5101 of the second frame bar 5120 and the fourth frame bar 5140 relative to the vertical plane is greater than the offset degree of the first side surface 5210 relative to the vertical plane, so that the air guide surface 5101 sinks to the top of the cover 2000 Oil fumes near the surface are better guided to prevent oil fumes from spilling into other spaces in the kitchen.

As shown in FIG. 15 , in some embodiments, the sum of the heights of the grill bars 5200 and the tips 5230 is greater than the height of the frame 5100 , so that space can be more fully utilized.

Specifically, along the height direction of the grille 5000, that is, the up and down direction shown in Figure 15, the height of the frame 5100 is less than the sum of the heights of the grille bars 5200 and the tips 5230. In this way, when the grille 5000 is installed in the opening 2100, the height of the frame 5100 is smaller than the height of the grille 5000. When supported on the connecting piece 4000 (the second connecting part 4200), the grill bars 5200 can sink into the body 1000, which can compress the space of the body 1000 and make the overall thickness of the combination stove thinner. It is precisely because the air guide surface 5101 of the frame 5100 is designed to be more inclined than the first side 5210, which provides favorable conditions for reducing the thickness of the frame 5100.

Further, as shown in FIG. 15 , in some embodiments, the top surface of the grille bar 5200 is not higher than the top surface of the frame 5100 , for example, the top surface of the grille bar 5200 is flush with the top surface of the frame 5100 , or it can be The top surface of the grille bar 5200 is lower than the top surface of the frame 5100 . This can prevent the grille bars 5200 from protruding from the frame 5100 in the height direction and thereby hindering the cleaning process.

In some embodiments, the frame 5100 and the grille bars 5200 are made of plastic, so that the grille 5000 is lightweight and easy for users to grasp. For example, the frame 5100, the grille bars 5200, the tips 5230, the protrusions 5250, and the supports 5300 are all made of plastic and are integrally injection molded to reduce the weight of the grille 5000. Especially when oil mist is attached to the grille 5000 for a long time, the lightweight grille 5000 can reduce the difficulty of the user's grasp and avoid falling during the grasping process.

As shown in FIG. 1 , in some embodiments, the frame 5100 is generally rectangular, with a structure in which the length dimension is greater than the width dimension, and the grille bars 5200 are arranged along the direction of the length dimension of the frame 5100 . The combination stove is also elongated as a whole and has a structure in which the length dimension is greater than the width dimension. The length dimension of the frame 5100 and the length dimension of the combination stove are perpendicular to each other. In this way, when the grill 5000 is arranged in the combination stove, the grill 5000 will not occupy too much space in the left cooking area 2210 and the right cooking area 2220. And the grille bars 5200 are arranged along the length direction of the frame 5100 to better divide the first air guide area 5410 corresponding to the left cooking area 2210, and the second air guide area corresponding to the right cooking area 2220. District 5420.
