[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention realizes the fixed connection of the table top, chassis and frame by cooperating the bending part, the snap-fitting ribs with the supporting part and the snap-fitting groove on the frame, thereby reducing the difficulty of installing the table top and chassis on the frame. The installation of the table top and chassis is not affected by each other, which facilitates the subsequent replacement and maintenance of the table top and chassis. At the same time, the bending part, the snap-fitting ribs cooperate with the supporting part and the snap-fitting groove to realize the precise positioning between the chassis and the frame, and between the table top and the frame, thereby ensuring the installation accuracy of the table top, chassis and frame.

[0025] 2. The chassis of the present invention is fixedly installed in the frame, and the lower unit is arranged at the lower end of the chassis. The stove can be isolated from the heat of the lower unit through the chassis, thereby improving the heat insulation effect of the upper and lower ends of the stove.

[0026] 3. Compared with the traditional chassis, the chassis of the present invention is formed by stretching the plate in one piece, so there is no need to consider the connection relationship, there is no problem of installation accuracy of each component in the chassis, the chassis is not easy to deform, and the overall strength of the stove is greatly improved.

[0027] 4. The fixing parts and limiting brackets of the present invention limit the air intake pipe to both sides of the bottom plate, so that the air intake pipe is away from the burner and the lower machine, avoiding the air intake pipe from being affected by high temperature, which is conducive to the orderly operation of the gas in the air intake pipe.

[0030] 7. The air guide ribs of the present invention penetrate the air guide member along its length direction. The air guide ribs separate the air outlet of the air guide member into different air outlet channels, which not only prevents foreign objects from easily falling into the exhaust pipe, but also breaks up the exhaust airflow to improve the heat dissipation effect.

[0031] 8. The lower end of the outer flange of the present invention is provided with an anti-fool boss, which is matched with the anti-fool notch formed on the top of the crimping part.

DETAILED DESCRIPTION

[0047] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] like Figure 1-Figure 4 , Figure 6 As shown, the stove for the lower machine includes: a frame 3, the two sides of the top of the frame 3 are bent inward to form a support portion 31, and the upper end of the support portion 31 is formed with a snap-fit ​​groove 32; a chassis 2, the two sides of the chassis 2 are bent outward to form a bent portion 21, and the chassis 2 is fixedly connected to the support portion 31 through the bent portion 21; a table panel 1, the two sides of the bottom of the table panel 1 are formed with snap-fit ​​ribs 11, and the table panel 1 is snap-fitted with the snap-fit ​​groove 32 through the snap-fit ​​ribs 11.

[0049] Specifically, the bent portions 21 on both sides of the chassis 2 are fixedly connected to the supporting portions 31 on both sides of the frame 3 by screws, and accordingly, the chassis 2 is fixed in the frame 3; and the table panel 1 is mounted on the top of the frame 3, and the snapping rib 11 at the lower end of the table panel 1 is snapped into the snapping groove 32 at the upper end of the supporting portion 31. The snapping groove 32 is in the shape of a wine bottle with a larger front and a smaller back. Therefore, when the snapping rib 11 enters the front end of the snapping groove 32, relative sliding can be achieved at the front end of the snapping groove 32, and when the snapping rib 11 enters the rear end of the snapping groove 32, due to the smaller width of the rear end of the snapping groove 32, a clearance fit occurs between the snapping rib 11 and the snapping groove 32, and the snapping rib 11 is fixed in the snapping groove 32, and accordingly, the table panel 1 is fixed on the frame 3.

[0050] Furthermore, although the table panel 1 and the chassis 2 are both installed on the frame 3, there is still a height difference between the two. Therefore, there is no interference problem in the installation of the table panel 1 and the chassis 2. The steps for installing the table panel 1 and the chassis 2 on the frame 3 are: first, insert the chassis 2 into the frame 3 and fix the chassis 2 to the frame 3 with screws; then set the table panel 1 to the top of the frame 3, and fix the table panel 1 to the frame 3 by the snap-fitting cooperation between the snap-fitting ribs 11 and the snap-fitting grooves 32.

[0051] Furthermore, since the chassis 2 is fixedly installed in the frame 3, a lower machine is arranged at the lower end of the chassis 2, and the lower machine is preferably a steam oven. Therefore, the stove can isolate the heat of the lower machine through the chassis 2. In order to improve the insulation effect and prevent convection of hot air above and below the stove, insulation cotton, heat preservation cotton and other structures can be arranged under the chassis 2.

[0052] Compared with the complicated installation process of existing stoves, which requires first fixing the table top and the chassis together and then fixing the integrated structure of the table top and the chassis to the frame, the present invention achieves the fixed connection of the table top 1, the chassis 2 and the frame 3 only through the cooperation of the bending portion 21, the snap-fitting rib 11 and the supporting portion 31 and the snap-fitting groove 32 on the frame 3, thereby reducing the difficulty of installing the table top 1 and the chassis 2 on the frame 3. The installation of the table top 1 and the chassis 2 is not affected by each other, which facilitates the subsequent replacement and maintenance of the table top 1 and the chassis 2. At the same time, due to the cooperation of the bending portion 21, the snap-fitting rib 11 and the supporting portion 31 and the snap-fitting groove 32, the precise positioning between the chassis 2 and the frame 3, and the table top 1 and the frame 3 is achieved, thereby ensuring the installation accuracy of the table top 1, the chassis 2 and the frame 3.

[0053] The inner side surface of the bending portion 21 abuts against the outer side surface of the supporting portion 31 , and the upper end surface of the bending portion 21 is mounted on the top of the supporting portion 31 . The top of the bending portion 21 also forms a plurality of locking grooves 211 opening toward the supporting portion 31 .

[0054] Specifically, the inner side surface of the bending portion 21 abuts against the outer side surface of the support portion 31, and the outer side surface of the support portion 31 limits the inner side surface of the bending portion 21. Accordingly, the frame 3 also limits the chassis 2; and the upper end surface of the bending portion 21 is mounted on the top of the support portion 31, and the top of the support portion 31 supports the upper end surface of the bending portion 21. Accordingly, the frame 3 supports both ends of the chassis 2, ensuring the stable setting of the chassis 2 on the frame 3; the locking groove 211 opening toward the support portion 31 facilitates the screws to enter the locking groove 211 and can quickly fix the chassis 2 to the frame 3.

[0055] like Figure 5As shown, the chassis 2 includes a bottom plate 22, which protrudes upward to form a first stretching area 221, and the first stretching area 221 protrudes upward to form a second stretching area 222. The burner 4 is fixedly installed on the second stretching area 222, and the burner 4 can pass through the through hole of the table panel 1.

[0056] Specifically, the chassis 2 is an integrated plate stretching structure, the first stretching zone 221 is higher than the bottom plate 22, and the second stretching zone 222 is higher than the first stretching zone 221. Therefore, the second stretching zone 222 is much higher than the bottom plate 22. The burner 4 is installed on the second stretching zone 222, and the installation height of the burner 4 is adjusted to avoid installing a bracket at the lower end of the burner 4, thereby reducing one installation component.

[0057] Compared with the traditional chassis which is made of several parts welded or fixedly connected, the chassis of the present invention is formed by stretching the plate as a whole. There is no need to consider the connection relationship, and there is no problem of installation accuracy of each component in the chassis. There is no need for welding, and the chassis is not easy to deform, which greatly improves the overall strength of the stove.

[0058] A lap joint 223 is formed at the rear end of the base plate 22, and the lap joint 223 is supported on the rear plate of the frame 3; a fixing part 224 is formed at the front end of the base plate 22 near the bending part 21, and the lower end of the air intake pipe 9 is supported in the fixing part 224, and the upper end of the air intake pipe 9 is limited by the limiting bracket 5 fixed on the base plate 22; the fixing part 224 and the limiting bracket 5 limit the air intake pipe 9 from sliding up and down and left and right, and the position setting of the fixing part 224 and the limiting bracket 5 also limits the air intake pipe 9 to both sides of the base plate 22, so that the air intake pipe 9 is away from the burner 4 and the lower machine, avoiding the air intake pipe 9 from being affected by high temperature, which is conducive to the orderly operation of the gas in the air intake pipe 9.

[0059] like Figure 7-12 As shown, the stove for the lower machine also includes: an exhaust pipe 6, which is fixedly mounted on the rear plate of the frame 3, and the side of the exhaust pipe 6 is connected to a heat dissipation pipe 10, and the heat dissipation pipe 10 can introduce the steam of the lower machine into the exhaust pipe 6, and the exhaust pipe 6 is supported by a crimping piece 7, and an air guide piece 8 is inserted into the crimping piece 7.

[0060] The present invention discharges the steam in the heat dissipation pipeline 10 from the lower end of the exhaust pipe 6 and the upper end of the air guide 8 through the combined structure of the exhaust pipe 6, the crimping piece 7 and the air guide 8, so that the steam in the heat dissipation pipeline 10 is dispersed, which is beneficial to the normal operation of the stove.

[0061] A long hole 61 is formed on the side of the exhaust pipe 6 facing the table panel 1, and the long hole 61 corresponds to the through hole 73 running from top to bottom in the crimping part 7. The shapes of the long hole 61 and the through hole 73 are basically the same. The long hole 61 and the through hole 73 are used to guide the discharge of steam. The long hole 61 and the through hole 73 arranged in the exhaust pipe 6 and the crimping part 7 constitute a condensation channel for steam, and the overlapping between the exhaust pipe 6 and the crimping part 7 prolongs the condensation time of steam in the condensation channel, reduces the temperature of steam when it is discharged, and is conducive to the steam becoming condensed water and flowing into the lower end of the exhaust pipe 6. Among them, the crimping part 7 is preferably made of metal material. The metal material has good thermal conductivity and can transfer the heat generated by liquefaction more quickly, so that the metal material itself maintains a lower temperature. Therefore, the crimping part 7 made of metal material is more conducive to improving the condensation effect of steam; the crimping plane 62 extends from the top of the exhaust pipe 6.

[0062] The upper end of the crimping part 7 extends outward to form an upper boss 71, and the bottom of the crimping part 7 extends outward to form a lower boss 72. A groove 721 is also formed in the lower boss 72. The crimping part 7 is fixedly mounted on the table panel 1 through the upper boss 71. The connection between the upper boss 71 and the table panel 1 can be a screw connection or a plug-in fit. The crimping part 7 is in contact with the crimping plane 62 of the exhaust pipe 6 through the lower boss 72. A sealant or a sealing ring can be provided in the groove 721 of the lower boss 72. The sealant or sealing ring in the groove 721 is used to improve the sealing degree of the contact between the crimping part 7 and the exhaust pipe 6, so that steam will not leak from the connection between the crimping part 7 and the exhaust pipe 6.

[0063] Specifically, when the table panel 1 is fixed to the frame 3, the crimping part 7 moves with the table panel 1, and the crimping part 7 presses the crimping plane 62 of the exhaust pipe 6 through the lower boss 72, further realizing automatic compression between the crimping part 7 and the exhaust pipe 6, thereby improving the convenience of installation between the exhaust pipe 6 and the crimping part 7.

[0064] The air guide 8 includes an air guide body 81 and an outer edge flange 82 arranged around the air guide body 81. The lower end of the outer edge flange 82 abuts against the table panel 1. A glue groove 821 is provided in the outer edge flange 82. The opening of the glue groove 821 faces one end of the crimping part 7. The glue groove 821 can be filled with sealant. The air guide 8 helps the air guide 8 to be fixedly installed on the table panel 1 by the sealant filled in the glue groove 821. The air guide body 81 is inserted into the upper end of the through hole 73 of the crimping part 7, which facilitates the air guide 8 to be fixedly installed in the crimping part 7.

[0065] An anti-foolproof boss 83 is provided at the lower end of the outer flange 82, and the anti-foolproof boss 83 is adapted to the anti-foolproof notch 74 formed at the top of the crimping part 7. The anti-foolproof boss 83 and the anti-foolproof notch 74 help to quickly position and install the air guide part 8 and the crimping part 7.

[0066] The air guide piece 8 includes an internal air guide rib 84, which is located at the air outlet of the air guide piece 8. The air guide rib 84 penetrates the air guide piece 8 along the length direction of the air guide piece 8. The air guide rib 84 separates the air outlet of the air guide piece 8 into different air outlet channels, which not only prevents foreign objects from easily falling into the exhaust pipe 6, but also breaks up the exhausted airflow to improve the heat dissipation effect; the height dimension of the air guide rib 84 is smaller than the height dimension of the air guide piece 8, which prevents the height dimension of the air guide rib 84 from being too large and affecting the connection between the air guide piece 8 and the crimping piece 7. At the same time, it also reduces the volume of the air guide rib 84, making it easier to fix it on the air guide piece 8.

[0067] The air guide rib 84 is fixed to the inner wall of the air guide member 8 by a plurality of connecting ribs 85 . In order not to affect the discharge of gas, the connecting ribs 85 are preferably four and are respectively located at the front, back, left and right ends of the air guide rib 84 .

[0068] The outer wall of one side of the air-guiding rib 84 is an outwardly inclined surface. The inner wall of the air-guiding member 8 opposite the inclined surface of the air-guiding rib 84 is also an outwardly inclined surface. These two inclined surfaces form an oblique air outlet channel, which is used to guide the airflow away from the cavity wall to reduce the amount of steam approaching the cavity wall. The oblique air outlet channel forms an angle of 10-40° with the horizontal plane, and of course, the preferred angle is 20°.

[0069] The outer wall on the other side of the air-guiding rib 84 is a vertical surface, and the inner wall of the air-guiding member 8 opposite to the vertical surface of the air-guiding rib 84 is also a vertical surface. The two vertical surfaces constitute a straight air outlet channel. The gas ejected from the straight air outlet channel intersects with the gas ejected from the oblique air outlet channel to disperse the steam output by the air-guiding member 8 and avoid accidents of high-temperature burns.

[0070] The present invention provides a crimping piece on the exhaust pipe, which extends the length of the condensation channel and correspondingly prolongs the condensation time of steam in the condensation channel, reducing the temperature of the steam when it is discharged, which is conducive to the steam being converted into condensed water and flowing into the lower end of the exhaust pipe, thereby avoiding damage to the stove or injury to personnel caused by the discharge of steam with excessively high temperature.

[0071] On the other hand, the air guide piece is plugged into the crimping piece, and the air guide piece divides the steam into multiple flow directions through the air guide ribs, which not only improves the heat dissipation effect of the steam, but also avoids the steam being concentrated in one direction and causing accidents such as high temperature burns.

[0072] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
