Detailed implementation manners

[0035] In order to make the objectives, technical solutions, and advantages of this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0036] Please refer to Figures 1-3 , an integrated stove 1 is provided in an embodiment of this application. The integrated stove 1 is a kitchen appliance that combines a cooking stove and a cooking device (not shown in the figure). Among them, the cooking device can be a steam box, an oven, a steam oven, etc. The type of the cooking device is not specifically limited in the embodiment of this application.

[0037] The integrated stove 1 may include a stove shell 10 and an exhaust device 20. The stove shell 10 includes a stove housing 11 and a stove panel 12. An accommodation cavity 11a is provided inside the stove housing 11. Part of the exhaust device 20 is installed in the accommodation cavity 11a, and the stove panel 12 is used to cover the accommodation cavity 11a. That is to say, the stove panel 12 covers the opening of the accommodation cavity 11a to prevent the exhaust device 20 from being exposed to the air, thereby playing a role in protecting the exhaust device 20.

[0038] Furthermore, an installation opening 12a is provided on the stove panel 12, and the installation opening 12a communicates with the accommodation cavity 11a. It can be understood that the exhaust device 20 is installed in the accommodation cavity 11a, and the exhaust gas in the exhaust device 20 flows out of the integrated stove 1 through the installation opening 12a. The exhaust gas can be understood as at least one of air, flue gas, and water vapor. It should be noted that the installation opening 12a can be provided at the rear side of the stove panel 12 to prevent the exhaust gas flowing out of the exhaust device 20 from affecting the user.

[0039] The following details the exhaust device 20.

[0040] Please refer to Figures 4-6 , the exhaust device 20 includes a water box support member 21, a fan assembly 22, a joint assembly 23, and a water receiving box 24. Among them, at least part of the water box support member 21, the fan assembly 22, the joint assembly 23, and the water receiving box 24 are all installed in the accommodation cavity 11a.

[0041] Please refer to Figures 5-6, specifically, the water box support 21 includes an air duct housing 211 and a steam duct housing 212 surrounding the periphery of the air duct housing 211. The air duct housing 211 has an air duct 211a, and a steam duct 212a is configured between the air duct housing 211 and the steam duct housing 212; the fan assembly 22 is connected to and communicates with the air duct housing 211. The fan assembly 22 is a device that converts mechanical energy into airflow energy, and the fan assembly 22 is used to achieve functions such as ventilation, heat dissipation, and air supply; the joint assembly 23 is connected to and communicates with the steam duct housing 212; the water receiving box 24 is partially installed in the water box support 21, and the water receiving box 24 can be used to receive the condensed water that flows back due to steam condensation; the water receiving box 24 has an exhaust port 24a, and the exhaust port 24a communicates with both the air duct 211a and the steam duct 212a, so that the air in the air duct 211a and the steam in the steam duct 212a are mixed at the exhaust port 24a.

[0042] It can be understood that when the fan assembly 22 is operating, air is sucked into the fan assembly 22 and blown into the air duct 211a by the rotation of the fan assembly 22; one end of the joint assembly 23 is connected to the steam duct housing 212, and the other end of the joint assembly 23 is connected to the steam exhaust pipe (not shown in the figure) of the cooking device. When the cooking device is operating, the steam generated by the cooking device can flow into the steam duct 212a through the steam exhaust pipe and the joint assembly 23; and because the exhaust port 24a communicates with both the air duct 211a and the steam duct 212a, as the air in the air duct 211a and the steam in the rectifying duct flow, after the air in the air duct 211a and the steam in the rectifying duct are mixed at the exhaust port 24a, the steam drives the air to be discharged to the outside of the integrated stove 1 in a natural entrainment manner. Furthermore, driven by the fan assembly 22, the air can be quickly mixed with the steam at the exhaust port 24a, and the air has a certain flow rate at this time, so the speed of discharging the mixed steam and air can be increased to improve the speed of discharging the steam from the integrated stove 1. At the same time, because the speed of discharging the steam from the integrated stove 1 is increased, the situation of the steam condensing into condensed water in the steam duct 212a is reduced. In this way, it is possible to prevent too much condensed water in the steam duct 212a from flowing back into the cooking device through the steam duct 212a, the joint assembly 23, and the steam exhaust pipe.

[0043] In addition, when the cooking device is working, the temperature of the oil fume and steam generated by the cooking device exceeds 100 degrees Celsius. If the steam is directly discharged from the exhaust port 24a to the outside of the cooking device, since the temperature of the oil fume and steam generated by the cooking device is relatively high, it is easy to scald the user. Therefore, by arranging a fan assembly 22 in the exhaust device 20, and as long as the cooking device is in the working state, the fan assembly 22 will work. When the steam and air are mixed at the exhaust port 24a, the temperature of the steam will decrease, that is, the steam is discharged from the exhaust port 24a to the outside of the integrated stove 1 only after the temperature is reduced, so as to prevent the user from being scalded by the steam.

[0044] It should be noted that the type of the fan assembly 22 is not specifically limited in the embodiments of the present application. Exemplarily, the fan assembly 22 can be a cross-flow fan or an axial-flow fan.

[0045] In the embodiments of the present application, an air duct housing 211 and a steam duct housing 212 surrounding the air duct housing 211 are arranged on the water box support 21. The air duct housing 211 has an air duct 211a, and a steam duct 212a is configured between the air duct housing 211 and the steam duct housing 212; the water receiving box 24 has an exhaust port 24a, and the exhaust port 24a is communicated with the air duct 211a and the steam duct 212a. Driven by the fan assembly 22, the air in the air duct 211a and the steam in the steam duct 212a are mixed at the exhaust port 24a, and at the same time, the steam can carry the air and flow out of the integrated stove 1 from the exhaust port 24a. In this way, on the one hand, the speed of the steam discharged from the integrated stove 1 can be increased, and on the other hand, the steam temperature can be reduced to prevent the user from being scalded by the steam.

[0046] Please refer to Figure 7 , in some embodiments, the air duct housing 211 includes an air inlet housing 2111 and an air outlet housing 2112.

[0047] Specifically, the air inlet housing 2111 is connected and communicated with the fan assembly 22; the air outlet housing 2112 is smoothly connected and communicated with the air inlet housing 2111. It can be understood that when the fan assembly 22 works, the fan assembly 22 forms a negative pressure, and air enters the air inlet housing 2111 from the ventilation port of the air inlet housing 2111, and enters the air outlet housing 2112 from the air inlet housing 2111 under the action of the fan assembly 22. Among them, an air inlet section 2111a is formed in the air inlet housing 2111, and an air outlet section 2112a is formed in the air outlet housing 2112. The air inlet section 2111a and the air outlet section 2112a are communicated to form an air duct 211a. That is, air enters from the air inlet section 2111a and flows out from the air outlet section 2112a, and the air outlet section 2112a is communicated with the exhaust port 24a, so that air and steam are mixed at the exhaust port 24a.

[0048] Please continue to refer to Figure 7, Further, in some embodiments, the central axis of the air inlet housing 2111 is disposed at an angle to the central axis of the air outlet housing 2112. That is, by setting the air inlet housing 2111 and the air outlet housing 2112 at an angle, the transmission direction of the air flow is changed, so as to realize the air flowing to the exhaust port 24a. In addition, compared with the straight-line transmission direction of the air flow in the related art, in the embodiment of the present application, by setting the central axis of the air inlet housing 2111 at an angle to the central axis of the air outlet housing 2112, the flow direction of the air flow can be set at an angle to shorten the air flow path.

[0049] Please refer to Figures 7-8 , In some embodiments, the water tank support 21 further includes a front side plate 213, a rear side plate 214, a first partition 215, and a second partition 216.

[0050] Specifically, the rear side plate 214 and the front side plate 213 are oppositely disposed in the front-rear direction A-A of the exhaust device 20; the first partition 215 is connected to both the front side plate 213 and the rear side plate 214; the second partition 216 is connected to both the front side plate 213 and the rear side plate 214, and the second partition 216 is oppositely disposed to the first partition 215 in the left-right direction B-B of the exhaust device 20. Among them, the front side plate 213, the rear side plate 214, the first partition 215, the second partition 216, and the air duct housing 211 together constitute the steam duct housing 212. It can be understood that the steam generated during the operation of the cooking device flows to the joint assembly 23, and since the joint assembly 23 is connected and communicated with the steam duct housing 212, the steam flows into the steam duct 212a through the joint assembly 23, so that the steam in the steam duct 212a is mixed with the air in the air duct 211a at the exhaust port 24a.

[0051] Please continue to refer to Figures 7-8 , In some embodiments, the air duct housing 211 penetrates through the front side plate 213 and is connected to the front side plate 213, so that the air duct housing 211 is connected and communicated with the fan assembly 22. That is, since the air duct housing 211 penetrates through the front side plate 213, the air duct housing 211 extends to the side of the front side plate 213 close to the fan assembly 22, so that it is convenient to connect the air duct housing 211 with the fan assembly 22.

[0052] Further, the air duct housing 211 is spaced from the first partition 215, the second partition 216, and the rear side plate 214 to form the steam duct 212a. It can be understood that the steam in the steam duct 212a is looped in the gap formed by the air duct housing 211, the first partition 215, the second partition 216, and the rear side plate 214 to increase the steam flow area, and thus improve the steam discharge speed.

[0053] Please refer toFigure 7 In some embodiments, the fan assembly 22 includes a fan body 222, a fan bracket 221, and a fan cover plate 223.

[0054] Specifically, the fan body 222 is connected to the air duct housing 211 and communicates with the air duct 211a. The fan body 222 generally consists of a motor and an impeller. The working principle of the fan body 222 is mainly to drive the impeller to rotate at a high speed through the motor, squeeze and accelerate the air, so that the air obtains energy and generates an air flow. That is, under the action of the fan body 222, the air flows into the air duct housing 211.

[0055] The fan bracket 221 is connected to the front side plate 213 and the fan body 222. That is, the fan bracket 221 is connected to the fan body 222 to fix the fan body 222 on the fan bracket 221; the fan bracket 221 is connected to the front side plate 213 to be fixed on the front side plate 213, so as to fix the fan assembly 22 on the front side plate 213.

[0056] The fan cover plate 223 is connected to the fan body 222, and the fan cover plate 223 and the fan bracket 221 are arranged back to back in the up-down direction C-C of the exhaust device 20. It can be understood that when the fan assembly 22 works, it needs to inhale external air, but the fan assembly 22 may also inhale other impurities into the fan body 222, resulting in damage to the impeller. Therefore, by setting the fan cover plate 223, the impeller can be protected from other impurities. At the same time, the fan cover plate 223 can effectively guide the air flow to ensure the smooth operation of the fan body 222.

[0057] Please continue to refer to Figure 7 Specifically, in some embodiments, the front side plate 213 is provided with a first through hole 213a, and the fan bracket 221 is provided with a second through hole 221a; the exhaust device 20 further includes a first screw connector (not shown in the figure), and the first screw connector passes through the first through hole 213a and the second through hole 221a to fix the fan bracket 221 on the front side plate 213. That is, by passing the first screw connector through the first through hole 213a and the second through hole 221a, the fan bracket 221 is fixedly connected to the front side plate 213, thereby improving the stability of the fan bracket 221 installed on the front side plate 213.

[0058] Please continue to refer to Figure 7, in some other embodiments, the blower body 222 is provided with a third through hole 222a; the blower bracket 221 is provided with a fourth through hole 221b; the exhaust device 20 further includes a second screw member (not shown in the figure), and the second screw member passes through the third through hole 222a and the fourth through hole 221b to mount the blower bracket 221 on the blower body 222. It can be understood that by passing the second screw member through the third through hole 222a and the fourth through hole 221b, the fixed connection between the blower bracket 221 and the blower body 222 is realized, thereby improving the stability of the blower bracket 221 mounted on the blower body 222.

[0059] Please continue to refer to Figure 7 , in still some other embodiments, the front side plate 213 is provided with a first through hole 213a; the blower bracket 221 is provided with a second through hole 221a and a fourth through hole 221b; the blower body 222 is provided with a third through hole 222a; the exhaust device 20 includes a first screw member and a second screw member. Among them, the first screw member passes through the first through hole 213a and the second through hole 221a, and the second screw member passes through the third through hole 222a and the fourth through hole 221b. That is to say, through the blower bracket 221, the blower body 222 is fixedly connected to the front side plate 213 to realize the connection between the blower assembly 22 and the front side plate 213, thereby improving the stability of the blower assembly 22 mounted on the front side plate 213.

[0060] Please refer to Figure 7 and Figure 9 , furthermore, the stove housing 11 includes a stove bottom shell 111, and the stove bottom shell 111 has a fifth through hole 111a; the front side plate 213 is further provided with a sixth through hole 213b; the integrated stove 1 further includes a third screw member (not shown in the figure), and the third screw member passes through the fifth through hole 111a and the sixth through hole 213b to mount the water box support member 21 on the stove bottom shell 111. That is to say, by the third screw member, the water box support member 21 can be fixed on the stove bottom shell 111 to improve the stability of the installation between the water box support member 21 and the stove bottom shell 111.

[0061] Please refer to Figures 7-8 In some embodiments, the water box support member 21 further includes a left side plate 217 and a right side plate 218.

[0062] Specifically, the left side plate 217 is connected to the front side plate 213 and the rear side plate 214. The left side plate 217 and the first partition plate 215 are oppositely arranged in the left-right direction B-B of the exhaust device 20. The left side plate 217, the front side plate 213, the first partition plate 215 and the rear side plate 214 jointly enclose a first installation groove 21a; the right side plate 218 is connected to the front side plate 213 and the rear side plate 214, and the right side plate 218 and the second partition plate 216 are oppositely arranged in the left-right direction B-B of the exhaust device 20. The left side plate 217, the front side plate 213, the second partition plate 216 and the rear side plate 214 jointly enclose a second installation groove 21b; wherein, the right side plate 218 and the left side plate 217 are respectively located on the opposite sides of the whole formed by the first partition plate 215 and the second partition plate 216. That is, the first installation groove 21a and the second installation groove 21b are arranged at intervals in the left-right direction B-B of the exhaust device 20, and the steam duct housing 212 is between the first installation groove 21a and the second installation groove 21b. Wherein, at least part of the water receiving box 24 is installed in the first installation groove 21a and the second installation groove 21b, so that at least part of the water receiving box 24 is installed in the water box support member 21 to reduce the overall size of the exhaust device 20.

[0063] It should be noted that the water box support member 21 and the water receiving box 24 are detachably connected. It can be understood that during the exhaust process, the steam generated when the cooking device works can condense to form condensate, and the condensate can flow into the water receiving box 24. That is, the water receiving box 24 can be used to collect the condensate generated in the cooking device to prevent more condensate from flowing back into the internal space of the cooking device. And because the water box support member 21 and the water receiving box 24 are detachably connected, when the water receiving box 24 receives a large amount of condensate, the user can detach the water receiving box 24 and pour out the condensate received in the water receiving box 24 to facilitate the treatment of the condensate.

[0064] Please refer to Figure 8 Furthermore, in some embodiments, the water receiving box 24 includes a first water receiving box 241, a partition member 242 and a second water receiving box 243. The partition member 242 is connected to the first water receiving box 241, and the partition member 242 has an exhaust port 24a. The second water receiving box 243 is connected to the partition member 242, and the second water receiving box 243 is connected to the partition member 242, and the second water receiving box 243 and the first water receiving box 241 are arranged at intervals in the left-right direction B-B of the exhaust device 20. That is, the first water receiving box 241 is installed in the first installation groove 21a, and the second water receiving box 243 is installed in the second installation groove 21b, so that at least part of the water receiving box 24 is installed in the water box support member 21, thereby reducing the overall size of the exhaust device 20.

[0065] Please continue to refer to Figure 8, in some embodiments, the separator 242 includes a first separator sub-member 2421 and a second separator sub-member 2422.

[0066] Specifically, the first separator sub-member 2421 is connected to the first water receiving box 241, and the first separator sub-member 2421 has a first opening 2423 facing the first partition 215; the second separator sub-member 2422 is connected to the second water receiving member, and the second separator sub-member 2422 is disposed opposite to the first separator sub-member 2421 along the left-right direction B-B of the exhaust device 20, and the second separator sub-member 2422 has a second opening 2424 facing the second partition 216. It can be understood that, in order to enable the first water receiving box 241 to be better installed into the first installation groove 21a, and the second water receiving box 243 to be better installed into the second installation groove 21b, a first opening 2423 is provided in the first separator sub-member 2421 facing the first partition 215, and a second opening 2424 is provided in the second separator sub-member 2422 facing the second partition 216. Among them, the top end of the first partition 215 extends into the first opening 2423, and the top end of the second partition 216 extends into the second opening 2424. In this way, the water receiving box 24 can be installed in the water box support member 21.

[0067] In some embodiments, the exhaust device 20 further includes a seal, which is a fitting for sealing. Most seals are made of rubber materials, and the seals have characteristics such as corrosion resistance, tear resistance, and elasticity.

[0068] Please refer to Figures 8-9, Further, the water box support 21 further includes a bottom plate 219, and the bottom plate 219 is connected to the front side plate 213, the rear side plate 214, the first partition plate 215, and the second partition plate 216. The bottom plate 219 includes a surrounding frame 2191, and the surrounding frame 2191 is connected to and communicated with the steam duct housing 212 and the joint assembly 23. The surrounding frame 2191 extends from the bottom plate 219 toward the joint assembly 23 and is provided with a sealing installation groove 2192, and a seal is installed in the sealing installation groove 2192. It can be understood that when the cooking device is working, steam flows from the joint assembly 23 through the surrounding frame 2191 into the steam duct housing 212, and is mixed with the air in the air duct 211a at the exhaust port 24a and then discharged outside the integrated stove 1. However, the steam is likely to form condensate when it encounters the cold air outside. Most of the condensate can be received by the water receiving box 24, but a small part of the condensate will flow back from the steam duct 212a to the joint assembly 23. During the process of the condensate flowing back, since the joint assembly 23 is connected to the surrounding frame 2191, and there may be a gap between the joint assembly 23 and the surrounding frame 2191, the existence of this gap may cause the condensate to penetrate into the internal space of the cooking device, affecting other components of the cooking device and making it difficult for the user to clean the condensate inside the cooking device. Therefore, by installing the seal in the sealing installation groove 2192, the gap between the joint assembly 23 and the surrounding frame 2191 is sealed, thereby preventing the condensate from penetrating into the internal space of the cooking device. In this way, the sealing performance between the joint assembly 23 and the surrounding frame 2191 is improved.

[0069] Please refer to Figure 9 , Further, in some embodiments, the surrounding frame 2191 includes a first sub - surrounding frame 2193 and a second sub - surrounding frame 2194. The first sub - surrounding frame 2193 is connected to and communicated with the steam duct housing 212; the second sub - surrounding frame 2194 is connected to and communicated with the joint assembly 23, and the second sub - surrounding frame 2194 is in interference fit with the first sub - surrounding frame 2193 to form the sealing installation groove 2192. That is, a part of the second sub - surrounding frame 2194 extends into the first sub - surrounding frame 2193, so that the second sub - surrounding frame 2194 is in interference fit with the first sub - surrounding frame 2193, and another part of the second sub - surrounding frame 2194 extends toward the joint assembly 23, and the size of the second sub - surrounding frame 2194 is smaller than that of the first sub - surrounding frame 2193, so that another part of the second sub - surrounding frame 2194 forms the sealing installation groove 2192; when the second sub - surrounding frame 2194 is connected to and communicated with the joint assembly 23, after the seal is installed in the sealing installation groove 2192, the connection between the second sub - surrounding frame 2194 and the joint assembly 23 can be realized. In this way, the sealing performance between the second sub - surrounding frame 2194 and the joint assembly 23 is improved.

[0070] It should be noted that the second sub-enclosure 2194 and the first sub-enclosure 2193 can be an integral component, so as to reduce the installation steps of the exhaust device 20, thereby improving the convenience of installing the exhaust device 20.

[0071] Please refer to Figures 8-9 , in some embodiments, the joint assembly 23 includes a joint pipe 231, a connecting pipe 232, and a connecting member 233.

[0072] Specifically, the joint pipe 231 is connected and communicated with a steam exhaust pipe (not shown in the figure) of the cooking device; the connecting pipe 232 is connected and communicated with the joint pipe 231; the connecting member 233 is connected and communicated with the connecting pipe 232 and the enclosure 2191. That is, a seal is clamped between the outer peripheral wall of the enclosure 2191 and the inner peripheral wall of the connecting member 233, so that the seal is installed in the seal mounting groove 2192. In this way, the sealing performance between the joint assembly 23 and the enclosure 2191 can be improved.

[0073] It should be noted that the joint pipe 231, the connecting pipe 232, and the connecting member 233 can be an integral component. In this way, on the one hand, the convenience of installing the joint assembly 23 can be improved, and on the other hand, the penetration of condensed water into the internal space of the cooking device can be avoided. Of course, the joint pipe 231, the connecting pipe 232, and the connecting member 233 can also be separately provided, and the embodiments of the present application do not make specific limitations in this regard.

[0074] Please refer to Figure 9 , since the joint assembly 23 and the enclosure 2191 are detachably connected, in order to avoid loosening of the joint assembly 23 during installation. Therefore, the bottom shell 111 of the stove is provided with a seventh through hole 111b, and the connecting member 233 has an eighth through hole 233a; the integrated stove 1 further includes a fourth screwing member (not shown in the figure), and the fourth screwing member passes through the seventh through hole 111b and the eighth through hole 233a to fix the joint assembly 23 to the bottom shell 111 of the stove. That is, by passing the fourth screwing member through the seventh through hole 111b and the eighth through hole 233a, the fixed connection between the joint assembly 23 and the bottom shell 111 of the stove is realized, thereby improving the stability of the joint assembly 23 installed on the bottom shell 111 of the stove.

[0075] Please continue to refer to Figure 9 , further, in some embodiments, the central axis of the joint pipe 231 and the central axis of the connecting pipe 232 are arranged at an angle. That is, when the steam exhaust pipe of the cooking device is connected to the joint pipe 231, since the joint pipe 231 and the connecting pipe 232 are arranged at an angle, and the joint pipe 231 extends along the left-right direction B-B of the exhaust device 20, the steam exhaust pipe of the cooking device can extend from the back of the integrated stove 1 to be connected to the joint pipe 231. In this way, it is convenient to install the steam exhaust pipe of the cooking device on the joint pipe 231.

[0076] Please refer to Figure 2 and Figure 8 , in some embodiments, the exhaust device 20 further includes a breathable cover 26 for covering the exhaust port 24a to prevent external debris from entering the interior of the exhaust device 20 through the exhaust port 24a. The breathable cover 26 has a breathable opening 26 which is in communication with the exhaust port 24a. That is, the air in the air duct 211a and the steam in the steam duct 212a can be discharged from the breathable opening 26 to the outside of the integrated stove 1 after being mixed at the exhaust port 24a, so as to achieve the discharge of steam. At the same time, by providing the breathable opening 26 on the breathable cover 26, the pressure loss of the mixture of air and steam flowing out can be reduced, thereby increasing the steam discharge amount.

[0077] Further, in some embodiments, in the vertical direction C-C of the exhaust device 20, the distance between the inner wall of the breathable cover 26 and the top wall of the exhaust port 24a is greater than or equal to 5 mm. It can be understood that,

[0078] when the fan assembly 22 sucks in air, a negative pressure is generated at the air inlet of the fan assembly 22. If the distance between the top wall of the exhaust port 24a and the inner wall of the breathable cover 26 is relatively close, it is easy to cause a large pressure of the air at the exhaust port 24a, which affects the working efficiency of the fan assembly 22. Therefore, by setting the distance between the inner wall of the breathable cover 26 and the top wall of the exhaust port 24a to be greater than or equal to 5 mm, the distance between the breathable cover 26 and the top wall of the exhaust port 24a is increased, so as to reduce the pressure loss of the mixture of air and steam flowing out, and thereby improve the working efficiency of the fan assembly 22.

[0079] Please continue to refer to Figure 2 and Figure 8 , in some embodiments, the integrated stove 1 further includes a decorative plate 30 which is connected to the stove top plate 12 and protrudes from the stove top plate 12. Among them, the decorative plate 30 protrudes from the stove top plate 12 to prevent condensed water from overflowing onto the stove top plate 12 during the process of the exhaust device 20 discharging steam; the decorative plate 30 is used to cover the installation opening 12a to prevent external debris from entering the interior of the exhaust device 20 through the installation opening 12a.

[0080] Further, the decorative plate 30 has a third opening 30a, and the breathable cover 26 is installed on the decorative plate 30, and the third opening 30a is in communication with the exhaust port 24a. It can be understood that the breathable cover 26 is used to cover the third opening 30a and the exhaust port 24a, and the breathable opening 26 on the breathable cover 26 is in communication with both the third opening 30a and the exhaust port 24a, so that after the air and steam are mixed at the exhaust port 24a, they flow to the outside of the integrated stove 1 from the third opening 30a and the breathable opening 26.
