[0050] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] In this specification, the orientation terms such as up, down, left, right, front, back, front face, back face, top, bottom, etc. mentioned or possibly mentioned are defined with respect to the configuration shown in the drawings, and the words "inner" and "outer" respectively refer to the direction towards or away from the geometric center of a particular component, which are relative concepts, and thus can change accordingly depending on the different positions, different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0052] Referring to 1, Figure 2 ​​The integrated stove comprises a table board 1, a stove 2, a cooking device 3, and a steam condensation and recycling system. The stove 2 is arranged below the table board 1, and the cooking device 3 is arranged below the stove 2. The cooking device 3 is a device that generates steam during cooking, such as a steam oven. The steam condensation and recycling system is used to condense the steam generated in the cooking device 3, and finally discharge the steam to the outside. The condensed water formed in the condensation process is used for recycling in the cooking device 3.

[0053] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 In the embodiment, the steam condensation and recycling system comprises a transfer box 41, a condensation box 42, and a steam discharge device. The transfer box 41 is connected with a steam input pipe 43 and a condensed water return pipe 44. The transfer box 41 and the condensation box 42 are connected with a steam output pipe 45 and a condensed water return pipe 46. The condensation box 42 and the steam discharge device are connected with a steam discharge pipe 47. The steam discharge pipe 47 is provided with at least one pipe, and the specific number is determined according to actual needs.

[0054] The steam condensation and recycling system of the embodiment forms a steam discharge path and a condensed water discharge path. Overall, the steam discharge path sequentially passes through the cooking device 3, the steam input pipe 43, the transfer box 41, the steam output pipe 45, the condensation box 42, the steam discharge pipe 47, and the steam discharge device. The condensed water discharge path sequentially passes through the condensation box 42, the condensed water return pipe 46, the transfer box 41, the condensed water return pipe 44, and the cooking device 3.

[0055] In the embodiment, after the steam is discharged from the cooking device 3, the steam flows along the steam discharge path and is finally discharged to the outside. The steam passes through three pipes (the steam input pipe 43, the steam output pipe 45, and the steam discharge pipe 47) and two boxes (the transfer box 41 and the condensation box 42), which can prolong the total length of the steam flow path and effectively improve the cooling effect of the steam. The condensation box 42 can efficiently condense the steam. The transfer box 41 serves as a transfer structure for the steam flow and the condensed water flow. The inner wall of the transfer box 41 provides sufficient area for heat exchange with the steam, so that the transfer box 41 also functions as a condensation box. Therefore, the steam is effectively and strongly condensed as a whole, so that the water content of the steam discharged to the outside is greatly reduced, and the temperature of the steam is also greatly reduced. Therefore, the water stains formed on the top surface of the table board 1, the wall surface 11, and other parts can be reduced, which is convenient for the user to handle. The reduction of the steam temperature can also avoid the situation that the user is scalded.

[0056] In the embodiment, the condensed water discharge path formed by the steam condensation and recycling system can supply the condensed water to the cooking device 3 for recycling, which improves the recycling rate of the condensed water and achieves the purpose of saving water resources.

[0057] In the embodiment, the steam flows in the steam input pipe 43 and the steam output pipe 45 and contacts with the pipe wall sufficiently and forms part of the condensed water, the steam input pipe 43 is connected to one end of the transfer box 41 and the height of the one end is lower than the height of the other end, so that the condensed water formed in the steam input pipe 43 flows to the transfer box 41, the steam output pipe 45 is connected to one end of the transfer box 41 and the height of the one end is lower than the height of the other end connected to the condensing box 42, so that the condensed water formed in the steam output pipe 45 flows to the transfer box 41, the condensed return pipe 46 is connected to one end of the transfer box 41 and the height of the one end is lower than the height of the other end connected to the condensing box 42. Therefore, in the steam condensing and recycling system of the embodiment, a main branch of the condensed water formed in the condensed return pipe 46 flows to the transfer box 41, two sub-branches of the condensed water formed in the steam input pipe 43 and the steam output pipe 45 flow to the transfer box 41, the main branch of the condensed water and the two sub-branches of the condensed water converge in the transfer box 41, and the condensed water formed by the steam flowing through the transfer box 41, finally, most of the condensed water formed by the steam condensing and recycling system is sent back to the cooking device 3 through the condensed return pipe 44. Under the premise that the steam condensing and recycling system condenses most of the water in the steam, the main branch of the condensed water and the two sub-branches of the condensed water can ensure the smooth operation of the condensed water discharge path and avoid the situation that the water path (condensed water) blocks the steam path (steam), thereby improving the smoothness of the steam discharge and the condensed water circulation of the steam condensing and recycling system.

[0058] In the embodiment, the condensed return pipe 44 is connected to one end of the transfer box 41 and the height of the one end is lower than the height of the other end connected to the steam input pipe 43 and the height of the other end connected to the steam output pipe 45, so that the condensed water in the transfer box 41 can flow out of the condensed return pipe 44 smoothly and avoid the condensed water in the transfer box 41 flowing back into the steam input pipe 43 and the steam output pipe 45.

[0059] Referring to Figure 5 and combining Figure 2 In the embodiment, the transfer box 41 is a closed box structure, and the inner bottom surface has a water collecting groove 411, the condensed water flowing into the transfer box 41 from the condensed return pipe 46, the steam input pipe 43 and the steam output pipe 45 all directly flows into the water collecting groove 411, the water collecting groove 411 plays a role of collecting the condensed water in the transfer box 41, thereby improving the flowability of the condensed water in the transfer box 41, and the cooling water flowing in the water collecting groove 411 flows out through the condensed return pipe 44.

[0060] In the embodiment, the transfer box 41 also functions as a condensing box. The steam contacts the inner surface of the transfer box 41 to form part of the condensed water. In order to enable the part of the condensed water to flow quickly into the water collecting groove 411, the inner bottom surface of the transfer box 41 has a slope surface 412 connected to the side of the water collecting groove 411. The condensed water formed on the slope surface 412 flows into the water collecting groove 411. The condensed water formed on the inner surface of the transfer box 41 flows directly into the water collecting groove 411 or flows onto the slope surface 412 and then flows into the water collecting groove 411.

[0061] With reference to Figure 8 , Figure 9 , Figure 10 and in combination with Figure 2 , in the embodiment, the condensing return pipe 46 is connected to the end of the condensing box 42 at a height lower than the height of the end of the steam output pipe 45 connected to the condensing box 42 and the height of the end of the steam discharge pipe 47 connected to the condensing box 42. Thus, the condensed water formed in the condensing box 42 can flow smoothly into the transfer box 41 through the condensing return pipe 46, and the condensed water in the condensing box 42 is prevented from flowing back into the steam output pipe 45 and the steam discharge pipe 47.

[0062] In the embodiment, the condensing box 42 has a steam inlet 42a, a steam outlet 42b and a water return outlet 42c. The steam inlet 42a is connected to the steam output pipe 45, the steam outlet 42b is connected to the steam discharge pipe 47, and the water return outlet 42c is connected to the condensing return pipe 46.

[0063] In the embodiment, the condensing box 42 is provided with a condensing box partition 421. The condensing box partition 421 is opposite to the steam inlet 42a. The steam discharged into the condensing box 42 through the steam inlet 42a impacts the condensing box partition 421. Under the impact, the steam loses kinetic energy and its flow rate is reduced, thereby prolonging the contact time with the inner surface of the condensing box 42, enabling the steam to exchange heat with the condensing box 42 more sufficiently, and improving the condensing effect of the condensing box 42 on the steam.

[0064] It should be noted that the condensing box partition 421 not only reduces the flow rate of the steam, but also forms a high-quality heat exchange contact when the steam impacts the condensing box partition 421, thereby forming a large amount of condensed water on the condensing box partition 421 and improving the condensing effect of the condensing box 42 on the steam.

[0065] The steam inlet 42a and the steam outlet are respectively arranged on the opposite sides of the condensing box 42. At least one side of the condensing box partition 421 and the inner wall of the condensing box 42 have a gap for guiding the steam to pass through. Since the steam inlet 42a and the steam outlet are arranged oppositely, the condensing box partition 421 not only reduces the steam flow rate, but also prolongs the flow path length of the steam in the condensing box 42, thereby further improving the condensing effect.

[0066] In the embodiment, the two sides and the bottom of the condensing box partition 421 have gaps between the two inner sides and the inner bottom of the condensing box 42, respectively. After the steam hits the condensing box partition 421, it spreads to the edges of the condensing box partition 421 and flows through the gaps to the steam outlet 42b. As a result, two side steam flow paths d1 and a lower steam flow path d2 are formed in the condensing box 42.

[0067] In the embodiment, the condensing box 42 is provided with a reinforcing rib assembly 422. The reinforcing rib assembly 422 is connected to the inner top and inner sides of the condensing box 42. The reinforcing rib assembly 422 can improve the overall structural strength of the condensing box 42 and prolong the service life of the condensing box 42.

[0068] In the embodiment, the condensing box partition is connected to or integrated with the reinforcing rib assembly 422. The reinforcing rib assembly 422 can not only strengthen the structural strength of the condensing box 42, but also provide the connection of the condensing box partition 421 in the condensing box 42.

[0069] In the embodiment, the inner bottom of the condensing box 42 is inclined, so that the condensed water formed on the inner bottom of the condensing box 42 flows to the water return port 42c. The condensed water formed by the contact between the steam and the inner top and inner sides of the condensing box 42 also eventually drips or flows onto the inner bottom and finally flows to the water return port 42c.

[0070] In the embodiment, the bottom of the condensing box 42 is provided with a cooling fin group 423. When the heat exchanged by the condensing box 42 is transferred to the cooling fin group 423, the cooling fin group 423 can provide a larger surface area to dissipate heat. The cooling fin group 423 is composed of a series of fins spaced apart from each other. The fins are designed in a thin sheet or fin shape to increase their surface area. In this way, heat can be more easily dissipated to the surrounding air by convection.

[0071] For the specific structure of the condensing box 42, in the embodiment, the condensing box 42 comprises an upper cover body 424 and a lower sealing plate 425, the bottom of the upper cover body 424 has an opening, the bottom edge is connected with the top surface edge of the lower sealing plate 425 by adhesive, in order to increase the connection area, the bottom edge of the upper cover body 424 has a flange edge 426 protruding outward or inward, the flange edge 426 is attached to the top surface of the lower sealing edge and connected by adhesive, the adhesive not only plays a connecting role, but also seals the flange edge 426 and the lower sealing plate 425, avoiding the overflow of condensate water in the condensing box 42.

[0072] In order to further improve the sealing effect of the upper cover body 424 and the lower sealing edge, in the embodiment, the lower sealing plate 425 is provided with a plurality of overflow holes 425a along the edge, so that the adhesive connecting the flange edge 426 and the lower sealing plate 425 can overflow from the overflow holes 425a, thereby increasing the reliability of the adhesive seal and strengthening the sealing effect.

[0073] Referring to Figure 2 In the embodiment, the cooking appliance 2 comprises an upper cover plate 21 and a bottom plate 22 in an upper-lower positional relationship, the top of the cooking device 3 is provided with a top plate 31, and a cooling air duct L is formed between the top plate 31 of the cooking device 3 and the bottom plate 22 of the cooking appliance 2, the cooling air duct L is provided with an air guide mechanism L1 for generating cooling air flowing along the cooling air duct L, the air guide mechanism L1 can be set as a fan, a pump or the like, and the number thereof is reasonably set according to actual application requirements, and a plurality of air guide mechanisms L1 can be installed side by side to improve the air volume and air power. In the embodiment, the air guide mechanism L1 is arranged at the rear side of the cooling air duct L, and the cooling air generated by the air guide mechanism L1 flows from the right rear to the front. The transfer box 41, the condensing box 42, the steam input pipe 43, the steam output pipe 45, and the partial steam discharge pipe 47 are located in the cooling air duct L, and the cooling air as the cooling medium can fully exchange heat with the transfer box 41, the condensing box 42, the steam input pipe 43, the steam output pipe 45, and the steam discharge pipe 47, thereby greatly improving the condensing effect of the steam condensing and recycling system and further reducing the water content and temperature of the steam finally discharged to the outside. As the condensing box 42 is the most critical part of the steam condensing and recycling system, the cooling fin group 423 of the condensing box 42 is located in the cooling air duct L and fully exchanges heat with the cooling air, so that the heat convection is greatly improved, and the condensing effect of the condensing box 42 is most significantly improved.

[0074] In the embodiment, the transfer box 41 is located close to the downstream end of the cooling air duct L, and the condensing box 42 is located close to the upstream end of the cooling air duct L, that is, the transfer box 41 is located close to the front end of the cooling air duct L, and the condensing box 42 is located close to the rear end of the cooling air duct L. The cooling air first exchanges heat with the condensing box 42, especially the cooling fins group 423 at the bottom of the condensing box 42, and then the remaining cooling of the cooling air after passing through the condensing box 42 cools the transfer box 41 which has the function of the condensing box, which can effectively utilize the cooling capacity of the cooling air, thereby achieving the maximum utilization of cooling resources. Secondly, since the temperature of the steam gradually decreases along the steam discharge path, the overall temperature of the condensing box 42 is lower than that of the transfer box 41. The "cooler" cooling air exchanges heat with the condensing box 42, and the "hotter" cooling air exchanges heat with the transfer box 41, thereby forming a two-segment gradient temperature difference condensing mechanism, which is highly adapted to the gradual cooling and condensing of the steam discharge path, thereby achieving better overall condensing effect.

[0075] With reference to Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 11 The integrated stove of the embodiment needs to load the cookers 3 from front to back during assembly, so it is difficult to load the whole steam exhaust condensing and recycling system into the integrated stove before or after loading the cookers 3. Therefore, the transfer box 41, the steam input pipe 43, and the condensing return water pipe 44 are installed on the top plate 31, and the condensing box 42, the steam output pipe 45, and the condensing return water pipe 44 are arranged on the bottom plate 22. During the loading of the cookers 3, the steam output pipe 45 and the condensing return pipe 46 are connected to the transfer box 41.

[0076] In the embodiment, the transfer box 41 is provided with a first plug-in pipe 41a, one end of the steam output pipe 45 is provided with a steam plug-in pipe 451, the steam plug-in pipe 451 is installed on the bottom plate 22 and plugged into the first plug-in pipe 41a, and the plug-in direction of the steam plug-in pipe 451 and the first plug-in pipe 41a is adapted to the loading direction of the cookers 3, that is, the front-to-back direction. The steam output pipe 45 is a flexible pipe, and the steam plug-in pipe 451 is a hard pipe and is connected to the bottom plate 22, so that the steam output pipe 45 does not need to be manually connected during the loading of the cookers 3. When the cookers 3 are loaded to the installed position, the first plug-in pipe 41a is plugged into the steam plug-in pipe 451. Since the steam output pipe 45 is a flexible pipe, it does not need to be manually connected, so that the preset extension direction of the steam output pipe 45 is not changed, so as to avoid the accumulation of condensed water in the steam output pipe 45 and affect the flow of steam in the steam output pipe 45.

[0077] In the embodiment, the bottom plate 22 is provided with at least one limiting frame 451 connected with the steam output pipe 45, so that the horizontal height of the steam output pipe 45 gradually decreases along the direction of the condensed water flow in the pipe, which is the preset extension direction of the steam output pipe 45, so that the condensed water formed in the steam output pipe 45 can flow more smoothly into the transfer box 41 and will not be accumulated or even blocked in the steam output pipe 45.

[0078] In the embodiment, the steam plug-in pipe 451 is provided with a plug-in head 452 at one end of the first plug-in pipe 41a, the root of the plug-in head 452 is provided with at least one steam inlet 452a connected with the steam plug-in pipe 451, the caliber of the plug-in head 452 gradually decreases from the root or the middle to the head, and the change of the caliber of the plug-in head 452 makes the head of the plug-in head 452 more easily enter the first plug-in pipe 41a during the plug-in process, so as to avoid plug-in failure. The plug-in head 452 of the embodiment is composed of multiple petals and can also be provided in other shape structures.

[0079] In the embodiment, the steam plug-in pipe 451 is provided with a mounting seat 453, the mounting seat 453 is provided with a limiting column 4531, a plug hole is arranged at the corresponding position of the bottom plate 22, the limiting column 4531 is plugged into the plug hole to complete the positioning of the steam plug-in pipe 451, the mounting seat 453 is provided with at least one steam plug-in pipe mounting hole 4532, and the mounting seat 453 is fixedly connected with the bottom plate 22 through fasteners such as screws. In addition, the pipe body of the steam plug-in pipe 451 is provided with an annular sleeve groove 454 for sleeving a sealing ring (not shown in the figure) for sealing the gap between the steam plug-in pipe 451 and the first plug-in pipe 41a to avoid leakage of steam or condensed water.

[0080] In the embodiment, the transfer box 41 is provided with a second plug-in pipe 41b, and one end of the condensed return pipe 46 is plugged into the second plug-in pipe 41b. The condensed return pipe 46 is a hose, and since the condensed return pipe 46 only flows condensed water and does not flow steam, it is not necessary to maintain the extension direction of the condensed return pipe 46 when the cooking device 3 is loaded, and it is only necessary to satisfy that the horizontal height of one end of the condensed return pipe 46 connected with the transfer box 41 is lower than one end connected with the condenser box 42. Therefore, during the loading process of the cooking device 3, the movement of the cooking device 3 is stopped when the one end of the condensed return pipe 46 can reach the second plug-in pipe 41b, the plug-in of the condensed return pipe and the second plug-in pipe 41b is completed manually, and then the cooking device 3 is completely loaded into the installation position.

[0081] In the embodiment, when the one end of the condensed return pipe 46 is plugged into the second plug-in pipe 41b, the condensed return pipe 46 is curved, that is, the shortest length of the condensed return pipe 46 is extended, and there is enough space to manually implement the plug-in of the condensed return pipe 46 and the second plug-in pipe 41b, thereby reducing the difficulty of assembly.

[0082] In the embodiment, the top plate 31 is provided with a vertical steam conversion pipe 481, the bottom end of the steam conversion pipe 481 directly communicates with the cooking device 3, or communicates with the cooking device 3 through a steam connecting pipe 482, mainly according to the interface position of the cooking device 3 outputting steam. The top end of the steam conversion pipe 481 is connected to one end of the steam input pipe 43, and the horizontal height is higher than the horizontal height of the end of the steam input pipe 43 connected to the transfer box 41. The steam conversion pipe 481 functions as a pipeline connection to deliver steam, and lifts one end of the steam input pipe 43, so that the condensed water formed in the steam input pipe 43 can flow into the transfer box 41, and the condensed water can also be prevented from flowing back to the cooking device 3.

[0083] In the embodiment, the top plate 31 is provided with a fixing member 4811, which fixedly connects the steam conversion pipe 481 and the top plate 31, so as to avoid loosening and sliding downward of the steam conversion pipe 481, and to avoid the time effect of lifting the steam input pipe 43.

[0084] In the embodiment, the steam input pipe 43 is a hose, and the top plate 31 is provided with at least one fixing bracket 431 for connecting the steam input pipe 43, so that the horizontal height of the steam input pipe 43 gradually decreases along the direction of the condensed water flowing in the pipe, so as to avoid the accumulation of condensed water in the steam input pipe 43 and even block the flow of steam.

[0085] Referring to Figure 6 , Figure 12 , Figure 13 , Figure 14 , Figure 21 , Figure 22 In the embodiment, the table plate 1 has a through hole 1a penetrating upward and downward in the rear portion thereof, the upper cover plate 21 of the cooking device 2 is located below the table plate 1, and the upper cover plate 21 is formed with a water collecting groove 211 located in the middle portion and two water guiding grooves 212 connected to both sides of the water collecting groove 211 on the top surface corresponding to the through hole 1a, and the water collecting groove 211 and the water guiding grooves 212 are both formed by downward recessing of the top surface of the upper cover plate 21. The water guiding groove 212 has an inclined water guiding surface 212s, which is the groove bottom surface of the water guiding groove 212. The water guiding surface 212s is inclined, so that the water on the water guiding surface 212s can flow into the water collecting groove 211, and the water collecting groove 211 has a certain liquid holding capacity.

[0086] In the embodiment, the diversion surface 212s, i.e. the bottom surface of the diversion groove 212, has a first mounting hole 21a for connecting and mounting the steam exhaust device, specifically through a fastener 69. The steam exhaust device finally discharges the condensed steam from the steam condensing and recycling system to the outside. Although the water content in the steam has been greatly reduced, condensate water will still be formed in the steam exhaust device. When the sealing effect of the steam exhaust device is poor after a long period of use, some of the condensate water will penetrate out of the steam exhaust device along the fastener, drip on the diversion surface 212s, and flow from the diversion surface 212s to the water collecting groove 211, thereby achieving the water-proof effect.

[0087] In the embodiment, a part of the steam exhaust device is supported on the top surface of the platform 1. The platform 1 is provided with a water-proof sealing gasket 12 between the edge of the through hole 1a and the steam exhaust device, for preventing water on the platform 1 from dripping downward through the through hole 1a.

[0088] In the embodiment, it is possible that the water-proof sealing gasket 12 is not installed or locked in place during installation, resulting in a failure of the sealing part. In addition, the water-proof sealing gasket 12 may also be deformed after a long period of use, which also leads to a failure of the sealing part. At this time, a small amount of water on the platform 1 will drip downward through the through hole 1a, directly into the water collecting groove 211, or drip on the diversion surface 212s and then flow to the water collecting groove 211, thereby achieving the water-proof effect.

[0089] In the embodiment, the steam in the steam exhaust device has a relatively low water content after being condensed by the steam condensing and recycling system. Therefore, the amount of condensate water formed in the steam exhaust device is small, and the amount of condensate water penetrating out is also small, so that the amount of condensate water finally flowing into the water collecting groove 211 is small. When the sealing part of the water-proof sealing gasket 12 fails, the amount of water on the platform 1 finally flowing into the water collecting groove 211 through the through hole 1a is also small. Therefore, in general, the amount of water in the water collecting groove 211 will not reach the maximum threshold.

[0090] Firstly, the water collecting groove 211 has a liquid holding function and achieves the water-proof effect, so as to prevent water from flowing into the lower body and causing short circuit failure and other situations. Secondly, the amount of water flowing into the water collecting groove 211 is small, so that the water in the water collecting groove 211 can evaporate under natural conditions without the need for additional drainage structure to drain the water in the water collecting groove 211, thereby achieving the purpose of saving cost. Thirdly, when the integrated cooker is disassembled for cleaning, maintenance and repair, if water or water stains are found in the water collecting groove 211, it reminds the user to check whether the steam exhaust device has the conditions such as poor sealing effect, improper installation or locking of the water-proof sealing gasket 12, and deformation of the water-proof sealing gasket 12.

[0091] For the steam exhaust device, in the embodiment, it includes a steam exhaust box 5 and an integrated assembly 6 which is above the steam exhaust box 5. The top of the steam exhaust box 5 is provided with two steam exhaust holes 5a at the corresponding two guide surfaces 212s, and the bottom of the integrated assembly 6 is provided with two steam exhaust holes 6a which are connected with the steam exhaust holes 5a. The integrated assembly 6 is provided with an integrated assembly sealing ring 6b at the joint of the steam exhaust holes 5a and the steam exhaust holes 6a. The steam flows through the steam exhaust pipe 47, the steam exhaust box 5, the integrated assembly 6 and is exhausted to the outside.

[0092] In the embodiment, the steam exhaust pipe 47 flows the condensed steam into the steam exhaust box 5. The steam is divided into two parts in the steam exhaust box 5 and flows into the integrated assembly 6 through the steam exhaust holes 5a and the steam exhaust holes 6a respectively, and is exhausted to the outside by the integrated assembly 6. The joint between the steam exhaust box 5 and the integrated assembly 6 is sealed by the integrated assembly sealing ring 6b. After a long time of use, the sealing effect of the integrated assembly sealing ring 6b will be deteriorated due to aging and deformation. Therefore, the condensed water will seep out from the joint, and the seeped condensed water will flow onto the guide surface 212s and finally flow into the water collecting groove 211, thereby playing a waterproof role.

[0093] In the embodiment, the specific connection object of the first mounting hole 21a is the integrated assembly 6. Therefore, the condensed water flowing into the guide surface 212s through the fastener comes from the inside of the integrated assembly 6.

[0094] In the embodiment, the guide surface 212s is provided with a bulge structure 21b which is raised in the middle of the outer periphery. The first mounting hole 21a is formed at the center of the bulge structure 21b. The bulge structure 21b plays a role of guiding the condensed water, so that the condensed water can flow into the guide surface 212s along the bulge structure 21b, avoiding the condensed water flowing into the lower body through the fastener.

[0095] In the embodiment, the upper cover plate 21 is provided with a mounting groove 213 which connects the front side or / and the rear side of the guide groove 212. The mounting groove 213 is provided with a second mounting hole 21c. The steam exhaust box 5 is provided with a lug 51 which is embedded in the mounting groove 213 and is connected and mounted in the second mounting hole 21c by a fastener such as a screw. The mounting groove 213 is recessed downward from the upper cover plate 21 to prevent water leakage at this position, so that the condensed water can flow into the guide surface 212s and finally flow into the water collecting groove.

[0096] For the waterproof sealing gasket 12, in the embodiment, it includes a first sealing part 121 which is attached to the top surface of the table plate 1 and a second sealing part 122 which is attached to the hole wall of the through hole 1a. The actual sealing area is increased, thereby effectively improving the actual sealing effect.

[0097] In the embodiment, the bottom of the integrated assembly 6 is provided with a sealing groove 6c, and the first sealing part 121 of the waterproof sealing gasket 12 is embedded in the sealing groove 6c. The sealing groove 6c plays a positioning role for the waterproof sealing gasket 12, which can effectively reduce the probability of improper installation or locking of the waterproof sealing gasket 12 and improve the sealing performance thereof.

[0098] In the embodiment, the bottom surface of the first sealing part 121 is provided with a waterproof labyrinth groove 121a. The waterproof labyrinth groove 121a can prolong the penetration path of water, thereby further improving the overall sealing performance of the waterproof sealing gasket 12.

[0099] Referring to Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 For the integrated assembly 6, in the embodiment, the integrated assembly 6 has a front inclined surface 6A facing away from the wall surface 11 (i.e., facing the user) and a rear inclined surface 6B facing the wall surface 11. The interior of the integrated assembly 6 has a middle cavity r1 and side cavities r2 located on both sides of the middle cavity r1.

[0100] The middle cavity r1 is provided with a circuit board 61 for outputting and displaying cooking information on the front inclined surface 6A. The circuit board 61 can display relevant cooking information of the stove head, such as the fire power, and / or relevant cooking information of the cooking device 3, such as the temperature and / or the time. The circuit board 61 can also display relevant cooking information of both the stove head and the cooking device 3.

[0101] The two steam exhaust holes 6a are respectively connected to the two side cavities r2, so that the two parts of steam exhausted from the steam exhaust box 5 enter the two side cavities r2, respectively. The side cavity r2 corresponding to the rear inclined surface 6B is provided with a steam exhaust port 6C. The steam in the side cavity r2 is exhausted to the outside through the steam exhaust port 6C.

[0102] The integrated assembly 6 integrates the functions of cooking information display and steam exhaust, has good functional integration, and improves the user experience.

[0103] The front inclined surface 6A and the rear inclined surface 6B formed by the integrated assembly 6 are reasonably utilized.

[0104] For the front inclined surface 6A, the cooking information is displayed on the front inclined surface 6A, which is in the good observation field of view of the user, so that the user can clearly observe the relevant cooking information.

[0105] For the rear inclined surface 6B, the steam is exhausted in a rearward direction toward the wall surface 11 through the steam exhaust port 6C of the rear inclined surface 6B.

[0106] Firstly, the rearwardly inclined steam discharge direction reduces the area of the water stain area formed by the wall 11, and the steam condensation recovery system greatly reduces the water content of the steam, making it easier and more convenient for the user to handle the water stain.

[0107] Secondly, compared with the traditional upward steam discharge direction, the rearwardly inclined steam discharge direction can avoid contact with the pot, thereby avoiding the rusting of the pot after long-term use, and also avoiding the contact of the steam with the fire, which will rapidly evaporate and release a large amount of heat when it contacts the steam. The heat transfer will cause the fire temperature to rise, thereby making it red, which makes the user prone to make a wrong judgment that the stove head is malfunctioning.

[0108] Furthermore, when the user uses the pot to cook on the stove, the oil fume is discharged upward. If the steam is also discharged upward, the oil fume and the steam form a fog screen in front of the user, which reduces the visibility and makes the user's cooking experience poor. In the present embodiment, the rearwardly inclined steam discharge direction can quickly contact the wall 11 to form condensed water, thereby reducing the influence on the visibility in front of the user.

[0109] In addition, the steam discharge port 6C is arranged on the rear inclined surface 6B, so that the water stain, oil stain, and food debris splashed by the user when using the pot to cook are not easy to fall into the steam discharge port 6C.

[0110] In the present embodiment, the integrated assembly 6 includes a housing 62 and a display glass 63. The housing 62 has two partition plates 623 separating a middle cavity r1 and two side cavities r2, so that the middle cavity r1 and the two side cavities r2 are independent of each other. The housing 62 has a front housing surface 621 and a rear housing surface 622. The front housing surface 621 is provided with a housing middle window 62a corresponding to the middle cavity r1. The display glass 63 is attached to the front housing surface 621 of the housing 62. More specifically, the front housing surface 621 and the display glass 63 are attached together by adhesive. At least one circuit board fixing bracket 611 connecting the display glass 63 and the circuit board 61 is arranged between the display glass 63 and the circuit board 61. Generally, two circuit board fixing brackets 611 are arranged on both sides of the circuit board 61. The circuit board fixing bracket 611 is fixedly connected to the side edge of the circuit board 61 by fasteners such as screws. The circuit board fixing bracket 611 and the display glass 63 are connected together by adhesive.

[0111] In the present embodiment, the circuit board 61 is provided with a circuit board sealing strip 612 at the edge of the side facing the display glass 63. The circuit board sealing strip 612 is in close contact with the surface of the display glass 63. The circuit board sealing strip 612 is used to seal the circuit board 61 to prevent moisture from entering and causing short circuit.

[0112] In the embodiment, the integrated assembly 6 further comprises a decorative strip 64 which is attached to the bottom edge of the front surface 621 of the housing 62. The decorative strip 64 is also fixedly connected by adhesive and covers the bottom edge of the display glass 63. On one hand, the front bevel 6A of the integrated assembly 6 is more attractive. On the other hand, the decorative strip 64 can further enhance the sealing performance.

[0113] In the embodiment, the rear surface 622 of the housing 62 is provided with a housing side window 62c corresponding to the portion of the side cavity r2, so as to allow the vapor to be discharged from the side cavity r2 to the outside.

[0114] In the embodiment, the integrated assembly 6 further comprises two heat insulation compartments 65 which are respectively arranged in the two side cavities r2. The heat insulation compartments 65 are provided with heat insulation compartment windows 65c corresponding to the portion of the housing side window 62c, so that the vapor in the heat insulation compartments 65 is sequentially discharged to the outside through the heat insulation compartment windows 65c and the housing side window 62c. The arrangement of the heat insulation compartments 65 can avoid the heat conduction of the vapor to the middle cavity r1, so as to avoid the case that the temperature of the middle cavity r1 is too high to cause the damage of the circuit board 61, and prolong the service life of the circuit board 61.

[0115] In the embodiment, the outer wall of the heat insulation compartment 65 is provided with a plurality of supporting blocks 651 which are supported on the inner wall of the housing 62, so that an air insulation layer is formed between the heat insulation compartment 65 and the housing 62. Air is a good insulator with low thermal conductivity. The air insulation layer can further reduce the heat conduction, so that the heat insulation compartment 65 has better heat insulation effect.

[0116] In the embodiment, although the rear bevel 6B can prevent the water, oil stains and food debris generated during cooking from falling in, the integrated assembly 6 in the cooking environment can still be invaded by oil stains and water stains. Therefore, the heat insulation compartment 65 is provided with a water receiving box 66 which can receive the water stains, oil stains and the like which enter the heat insulation compartment 65 through the housing side window 62c and the heat insulation compartment window 65c in sequence from the outside, so as to avoid the pollution of the side cavity r2.

[0117] In the embodiment, the housing side window 62c is provided with a hanging groove 624 on both sides, and the water receiving box 66 is provided with two hanging ears 661 which are hung on the hanging grooves 624, so as to facilitate the removal and cleaning of the water receiving box 66.

[0118] In the embodiment, the integrated assembly 6 further comprises a steam exhaust cover 67 which is attached to the rear surface 622 of the shell 62, and the steam exhaust cover 67 has a steam exhaust port 67c, so that the steam in the side cavity r2 is discharged to the outside through the heat insulation compartment window 65c, the shell side window 62c and the steam exhaust port 67c in sequence, and the heat insulation compartment window 65c, the shell side window 62c and the steam exhaust port 67c form the steam discharge port 6C. The steam exhaust cover is provided with a limiting post on the surface facing the rear surface 622, and the rear surface 622 is provided with a corresponding insertion hole which is inserted with the limiting post, so as to facilitate the installation and removal of the steam exhaust cover. When cleaning and maintenance is needed, the steam exhaust cover is removed, and then the water collecting box 66 is removed.

[0119] In the embodiment, the steam exhaust port 67c comprises a plurality of steam exhaust grooves which extend transversely and are spaced from each other, so as to reduce the invasion of oil stains and water stains into the side cavity r2.

[0120] In the embodiment, the integrated assembly 6 further comprises a cover 68, and the bottom of the shell 62 is provided with an opening, and the cover 68 seals the bottom of the shell 62, so as to form the main structure of the integrated assembly 6, and the steam discharge hole 6a is formed on the cover 68.

[0121] In the embodiment, the shell 62 and the cover 68 are detachably connected, the top surface of the cover 68 is provided with a stepped structure 681 which defines the edge of the side cavity r2, and the shell 62 is provided with a connecting structure 625 which is attached to the stepped structure 681, and the two are connected by fasteners. In addition, the fasteners 69 penetrate the shell 62, the heat insulation compartment 65 and the cover 68 and are connected to the first mounting hole 21a, so that the overall structure of the integrated assembly 6 is more firm and stable and is not easy to loosen. The part of the top surface of the cover 68 which is located in the stepped structure 681 forms a condensed water return surface 682, so that the condensed water formed on the condensed water return surface 682 flows to the steam discharge hole 6a, and the possibility of the condensed water penetrating into the middle cavity r1 is reduced, and the safety of the setting environment of the circuit board 61 in the middle cavity r1 is further ensured.

[0122] In the embodiment, the stepped surface of the stepped structure 681 which is attached to the connecting structure 625 is an inclined surface, which is used to guide the condensed water in the gap between the stepped structure 681 and the connecting structure 625 to flow to the condensed water return surface 682, and the possibility of the condensed water penetrating into the middle cavity r1 is further reduced.

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
