Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a cleaning joint for an integrated stove and the integrated stove. Background Art

[0002] An integrated stove is a common kitchen appliance that integrates functional modules such as a stove, a range hood, and a steam oven. It can effectively reduce the space occupied by kitchen appliances and improve their performance.

[0003] A fan for oil fume extraction is installed inside the cabinet of the integrated stove. During the oil fume extraction process, the oil fume enters the fan and will partially adhere to the blades or the inner wall of the volute. After the integrated stove is used for a long time, the oil fume will accumulate inside the fan, thereby increasing the driving load of the fan, reducing the air volume, and easily generating odor inside the fan, affecting the user experience of the integrated stove.

[0004] The prior art provides an integrated stove that connects the steam exhaust pipe of the steam oven to the inner cavity of the bellows, thereby utilizing the hot steam generated during cooking to soften and clean grease adhering to the fan's interior. While this fan cleaning method can utilize the hot steam generated by the steam oven during cooking, it synchronizes the cooking and cleaning processes, making it difficult to meet user cleaning needs during non-cooking periods such as maintenance, and resulting in limited cleaning flexibility. Furthermore, when the steam oven door is opened, the pressure in the cooking chamber rapidly decreases, causing gas in the fan's inner cavity to flow back into the cooking chamber through the exhaust pipe under the negative pressure of the cooking chamber, contaminating the cooking chamber and the food inside, affecting both the cooking experience and the user experience of the integrated stove. Utility Model Content

[0005] One of the technical problems solved by the present invention is to provide a cleaning joint for an integrated stove, which can effectively solve the problem that the cleaning structure of the existing integrated stove is poor in convenience for cleaning the volute assembly and the oil smoke in the air duct flows back into the cooking cavity.

[0006] The second technical problem solved by the present invention is to provide an integrated stove, which can effectively solve the problems of poor cleaning convenience of the volute assembly in existing integrated stoves and the easy backflow of oil smoke in the air duct into the cooking cavity, thereby affecting the cooking experience.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0061] This embodiment provides an integrated stove, which can realize multiple cleaning methods of the volute assembly 201 inside the integrated stove, improve the automatic cleaning ability and cleaning effect of the integrated stove, and enhance the user experience of the integrated stove.

[0062] like Figures 1 to 3 As shown, the integrated stove includes a range hood module, a cooker 800, a cabinet 900, and a steamer 700. The cooker 800 is mounted on the top of the cabinet 900 for cooking. The range hood module includes a range hood head 600 and an air duct assembly 200. The range hood head 600 is mounted on the top of the cabinet 900 and located behind the cooker 800. The range hood head 600 has a smoke inlet and a smoke collection chamber connected to the smoke inlet. The air duct assembly 200 is mounted inside the cabinet 900 and includes a bellows 202 and a volute assembly 201 mounted inside the bellows 202. The air inlet of the volute assembly 201 is connected to the outlet of the smoke collection chamber, and the air outlet of the volute assembly 201 is connected to the smoke exhaust port on the cabinet 900. The steamer 700 is mounted on the cabinet 900 and has a steam cooking function. The steamer 700 can be, but is not limited to, a steamer or a steam oven, as long as it has a steam cooking function.

[0063] To clean the volute assembly 201 inside the integrated stove, the stove also includes a cleaning device with steam and water modes. When in steam mode, the cleaning device connects the inner cavity of the steam box 700 and the air cavity of the volute assembly 201, allowing steam inside the steam box 700 to be discharged into the volute assembly 201 through the cleaning device, thereby softening and cleaning the oil and dirt adhering to the interior of the volute assembly 201. When in water mode, the cleaning device can pass external cleaning water into the inner cavity to clean the interior of the volute assembly 201.

[0064] Specifically, if Figures 3 to 8 As shown, the cleaning device includes a cleaning joint 100. The cleaning joint 100 includes a four-way joint 1 and a valve assembly. The four-way joint 1 includes a cleaning channel 131, a water inlet channel 121, a steam channel 111 and an air inlet channel 141, all of which are open at the first end. The valve assembly is arranged in the four-way joint 1 and has an initial state, an exhaust state and an air intake state. When the valve assembly is in the initial state, the water inlet channel 121 is connected to the cleaning channel 131, and the steam channel 111 is separated from the cleaning channel 131, the air inlet of the air inlet channel 141 and the water inlet channel 121. When the valve assembly is in the exhaust state, the cleaning channel 131 is connected to the steam channel 111 and is separated from the water inlet channel 121, and the steam channel 111 is separated from the air inlet and the water inlet channel 121. When the valve assembly is in the air intake state, the steam channel 111 is connected to the air inlet and is separated from the water inlet channel 121 and the cleaning channel 131. The valve assembly can switch from the initial state to the exhaust state under the action of the steam inlet pressure of the steam channel 111, and the valve assembly can switch to the air intake state under the action of the negative pressure of the steam channel 111.

[0065] The cleaning connector 100 provided in this embodiment has a cleaning channel 131 connected to the air cavity of the volute assembly 201, the steam inlet of the steam channel 111 is connected to the cooking cavity through the exhaust pipe 400, the water inlet channel 121 is used to introduce external cleaning water, and the air inlet is connected to the external environment.

[0066] When the valve assembly is in the initial state, the water inlet channel 121 and the cleaning channel 131 are connected, allowing external cleaning water to enter the water inlet channel 121 through the first end of the water inlet channel 121 and flow through the valve assembly to the cleaning channel 131, so that the external cleaning water flows out through the first end of the cleaning channel 131 to clean the interior of the volute assembly 201, that is, the cleaning device is in the water washing mode. When steam exceeding a preset pressure enters the steam channel 111, the valve assembly moves to the exhaust state under the action of the steam inlet pressure, allowing hot steam in the cooking chamber to enter the cleaning channel 131 through the steam channel 111, thereby allowing steam to flow out of the cleaning channel 131 to soak and clean the interior of the volute assembly 201, that is, the cleaning device is in the steam washing mode. When negative pressure occurs in the steam channel 111, the valve assembly moves to the air intake state, allowing external air to enter the air intake channel 141 through the air inlet and flow into the steam channel 111, thereby eliminating the negative pressure in the steam channel 111.

[0067] That is, the cleaning connector 100 provided in this embodiment, when the cleaning connector 100 is in the initial state, can clean the inside of the volute assembly 201 by introducing external cleaning water into the water inlet channel 121, which is conducive to manual cleaning of the inside of the volute assembly 201 and improves the autonomy and flexibility of cleaning; when the cleaning connector 100 is in the exhaust state, the hot steam generated by the cooking cavity can enter the air cavity through the cleaning connector 100, so that the hot steam soaks the air cavity, thereby utilizing the hot steam generated by cooking and reducing the cost required for cleaning; because the cleaning connector 100 can automatically control the switching of the cleaning connector 100 between the initial state and the exhaust state by the steam inlet pressure of the steam channel 111, when the cleaning connector 100 is in the exhaust state, 00 can select the conduction mode of introducing external cleaning water or introducing hot steam while realizing automatic switching of the conduction mode, reducing the use cost of the cleaning joint 100 and simplifying the structure of the cleaning joint 100; furthermore, due to the provision of the air intake channel 141, the cleaning joint 100 can relieve the pressure of the steam channel 111 and the cooking cavity when there is a negative pressure inside the cooking cavity, ensuring the smooth opening of operations such as the door, and because when the cleaning joint 100 is in the air intake state, the air intake channel 141 and the steam channel 111 are separated from the cleaning channel 131, which can prevent the oil smoke inside the air cavity from flowing back into the cooking cavity through the steam channel 111, thereby preventing the cooking cavity from being contaminated, improving the cooking experience of the steamer 700, and improving the use experience of the integrated stove.

[0068] It is worth noting that when the cleaning connector 100 is applied to the integrated stove, when the cleaning connector 100 is in the initial state, the user can provide cleaning water to the cleaning connector 100 through the water inlet channel 121, thereby realizing manual cleaning of the volute assembly 201, or by arranging a water tank, a water pump, a control valve and other pipeline structures inside the integrated stove, to realize controlled water supply to the water inlet channel 121, thereby realizing automatic cleaning of the volute assembly 201.

[0069] Furthermore, when the steamer 700 is cooking, the hot steam in the cooking cavity is directly discharged to the volute assembly 201 through the steam channel 111 and the cleaning channel 131, thereby realizing automatic cleaning of the volute assembly 201 and utilizing the steam in the cooking cavity, avoiding the need for an additional steam generating device to generate hot steam. At the same time, it also eliminates the need for an additional structure for exhausting the cooking cavity, thereby simplifying the structure of the steamer 700, reducing the space occupied by the steamer 700, and reducing the cost of the integrated stove.

[0070] To simplify the structure of the valve assembly, in one embodiment, the valve assembly includes a first valve core 2 and a second valve core 3. The first valve core 2 permanently separates the water inlet channel 121 and the steam channel 111. The first valve core 2 has an initial conductive state that connects the water inlet channel 121 and the purge channel 131. Under the influence of steam inlet pressure, the first valve core 2 can switch to a steam-conducting state that connects the steam channel 111 and the purge channel 131. The second valve core 3 is movably disposed in the air inlet channel 141. The second valve core 3 has an initial blocked state that blocks the air inlet from the steam channel 111. Under the influence of negative pressure, the second valve core 3 can move to an air-conducting state that connects the air inlet to the steam channel 111.

[0071] When the first valve core 2 is in the initial conduction state and the second valve core 3 is in the initial blocking state, the valve assembly is in the initial state; when the first valve core 2 is in the steam conduction state and the second valve core 3 is in the initial blocking state, the valve assembly is in the exhaust state; when the first valve core 2 is in the initial conduction state and the second valve core 3 is in the intake conduction state, the valve assembly is in the intake state.

[0072] By setting the valve assembly as the first valve core 2 and the second valve core 3, it is convenient to set the structure and installation position of the first valve core 2 and the second valve core 3 respectively, thereby simplifying the structural setting of the valve assembly, reducing the structural difficulty of the valve assembly, and simplifying the structure of the four-way joint 1.

[0073] To simplify the structure of the cleaning connector 100, in one embodiment, the water inlet channel 121 and the steam channel 111 are located on the same straight line, thereby facilitating the switching of the first valve core 2 between the initial conduction state and the steam conduction state. In other embodiments, the water inlet channel 121 and the steam channel 111 may also be arranged at an angle. Furthermore, the cleaning channel 131 and the air inlet channel 141 are both arranged at an angle to the steam channel 111.

[0074] In one embodiment, the water inlet channel 121 is vertically arranged with its lower end connected to the cleaning channel 131, and the steam outlet of the steam channel 111 is located below the water inlet of the water inlet channel 121. As a result, water flowing into the water inlet channel 121 can flow toward the cleaning channel 131 under the action of gravity, eliminating the need for a driving structure to drive the water flow, further simplifying the structure of the cleaning connector 100 and reducing the cost of the cleaning connector 100. At the same time, this arrangement allows the first valve core 2 to remain in a position blocking the steam outlet under the impact of the incoming water flow when water enters the water inlet channel 121, thereby effectively preventing water in the water inlet channel 121 from entering the steam channel 111.

[0075] In one embodiment, the cleaning channel 131 and the air intake channel 141 are respectively located on opposite sides of the steam channel 111. Since the cleaning outlet of the cleaning channel 131 is closer to the volute assembly 201, the air intake channel 141 is arranged on the side of the steam channel 111 away from the cleaning channel 131, which is conducive to making the air intake further away from the volute assembly 201, thereby further reducing the probability of oil smoke at the volute assembly 201 entering the steam channel 111 through the air intake, thereby improving the cleanliness of the intake air; at the same time, this arrangement can also reduce the interference between the cleaning joint 100 and the volute assembly 201.

[0076] In one embodiment, the air inlet channel 141 and the cleaning channel 131 are both perpendicular to the steam channel 111 , so as to simplify the structure of the cleaning connector 100 and reduce the difficulty of manufacturing the cleaning connector 100 .

[0077] In another embodiment, the channels may be arranged in other ways. For example, the steam channel 111 may be L-shaped, with one side extending in the same direction as the water inlet channel 121 and the other side communicating with the air inlet channel 141. The air inlet channel 141 is parallel to and spaced apart from the water inlet channel 121. In another embodiment, the steam channel 111 may be arranged in other structural forms, as long as the water outlet of the water inlet channel 121 and the steam outlet of the steam channel 111 are arranged directly opposite each other along the direction of movement of the first valve core 2.

[0078] To simplify the structure of the cleaning joint 100, the four-way joint 1 includes a cleaning pipe 13, a water inlet pipe 12, a steam pipe 11, and an air inlet pipe 14. The first end of the cleaning pipe 13 forms a cleaning outlet. The second end of the cleaning pipe 13 is connected to the water outlet of the water inlet pipe 12 and the steam outlet of the steam pipe 11 to form a three-way structure. The air outlet of the air inlet pipe 14 is connected to the steam pipe 11 to form a two-way structure. The air inlet end of the air inlet pipe 14 forms an air inlet, and the inner cavity of the air inlet pipe 14 forms an air inlet channel 141; the inner cavity of the water inlet pipe 12 forms a water inlet channel 121, and the inner cavity of the steam pipe 11 forms a steam channel 111. This allows the four-way joint 1 to form a pipe joint structure with four connected pipe sections, reducing the cost of the four-way joint 1.

[0079] In other embodiments, the four-way joint 1 may also adopt a block structure, and the water inlet channel 121, the steam channel 111, the air inlet channel 141 and the cleaning channel 131 are provided inside the block structure.

[0080] In one embodiment, the first valve core 2 includes a first blocking member 22 and a first elastic member 21. The first elastic member 21 constantly applies an elastic force to the first blocking member 22 to block the steam outlet. The first blocking member 22 can slide to block the water outlet when the steam inlet pressure overcomes the elastic force of the first elastic member 21. This arrangement allows the first valve core 2 to stably maintain its initial conductive state when the steam inlet pressure in the steam passage 111 is zero or low, preventing pressure relief in the cooking chamber during initial steam introduction, which would otherwise result in a slow filling of the cooking chamber with steam. When the steam inlet pressure in the cooking chamber increases to a predetermined pressure, requiring exhaust, the steam inlet pressure in the steam passage 111 overcomes the elastic force of the first elastic member 21, pushing the first blocking member 22 toward the water outlet to block the water outlet, thereby opening the steam outlet and connecting the steam passage 111 to the cleaning passage 131. This allows steam exhaust and simultaneously cleans the interior of the volute assembly 201.

[0081] In one embodiment, the first elastic member 21 is disposed in the air inlet passage 141, and the first blocking member 22 is located on the side of the first elastic member 21 facing the steam passage 111. That is, the first elastic member 21 is in a compressed state, thereby constantly applying a force toward the steam passage 111 to the first blocking member 22, ensuring that the first blocking member 22 seals the outlet of the steam passage 111 when no steam is entering the steam passage 111. Furthermore, this arrangement prevents the first elastic member 21 from ever coming into contact with steam, reducing contamination of the first elastic member 21 by oil in the steam, improving the movement reliability of the first valve core 2, and facilitating cleaning of the connector 100. In other embodiments, the first elastic member 21 may also be located in the steam passage 111, with the first elastic member 21 located on the side of the first blocking member 22 away from the water inlet passage 121.

[0082] To limit the travel of the first blocking member 22 toward the steam passage 111, the cross-connector 1 has a stepped sealing surface surrounding the steam outlet, facing the water inlet passage 121. When the first valve core 2 is in the initial conduction state, the first blocking member 22 abuts against the stepped sealing surface. This stepped sealing surface limits the depth of the first blocking member 22's penetration into the steam passage 111 and ensures that the first blocking member 22 effectively blocks the steam outlet of the steam passage 111.

[0083] To simplify the structure of cleaning connector 100, water inlet channel 121 extends toward the steam outlet to form a cleaning communication channel 171. The inner diameter of cleaning communication channel 171 is equal to that of water inlet channel 121 and larger than that of steam channel 111. A blocking step is formed at the connection point between cleaning communication channel 171 and the steam outlet, and cleaning channel 131 communicates with cleaning communication channel 171. This arrangement facilitates the processing of cleaning connector 100 and, while the inner diameter of water inlet channel 121 meets the installation requirements of first valve core 2, reduces the inner diameter of steam channel 111, thereby reducing the cost and weight of cleaning connector 100.

[0084] Specifically, the water inlet pipe 12 extends toward the steam pipe 11 to define a cleaning connection portion 17. The inner cavity of the cleaning connection portion 17 forms a cleaning communication passage 171. The cleaning pipe 13 is connected to the cleaning connection portion 17. The cleaning connection portion 17 forms the connecting junction between the water inlet pipe 12, the steam pipe 11, and the cleaning pipe 13.

[0085] In other embodiments, a convex ring portion may be provided inwardly through the inner wall of the steam channel 111 , the inner hole of the convex ring portion forms a steam outlet, and the convex ring portion forms a blocking step surface on the side facing the water inlet channel 121 .

[0086] In one embodiment, in order to prevent the first blocking member 22 from deflecting during operation, the first valve core 2 also includes a first guide member 23. The first end of the first guide member 23 slides with the channel wall of the water inlet channel 121, and the second end of the first guide member 23 is connected to the first blocking member 22. A water passage 233 is provided inside the first guide member 23. When the first valve core 2 is in the initial conduction state, the water inlet channel 121 is connected with the cleaning channel 131 through the water passage 233. This ensures the reliability of the sliding fit between the first guide member 23 and the channel wall of the water inlet channel 121 while avoiding the influence of the setting of the first guide member 23 on the flow of water. At the same time, this setting also enables the water flow entering from the water inlet channel 121 to act on the central area of the first blocking member 22, thereby better ensuring that the first blocking member 22 stably and reliably blocks the steam outlet of the steam channel 111 under the action of water pressure.

[0087] The first guide member 23 includes a first guide cylinder portion 231 and a first connecting cylinder portion 232 that are coaxially connected. The outer diameter of the first connecting cylinder portion 232 is smaller than the outer diameter of the first guide cylinder portion 231. The first end of the first connecting cylinder portion 232 is connected to the bottom of the first guide cylinder portion 231, and the second end of the first connecting cylinder portion 232 is connected to the first blocking member 22. The bottom of the first guide cylinder portion 231 is provided with a bottom water hole that is connected to the inner cavity of the first connecting cylinder portion 232, and the side wall of the first connecting cylinder portion 232 is provided with a side water hole. The inner cavity of the first guide cylinder portion 231, the bottom water hole, the inner cavity of the first connecting cylinder portion 232 and the side water hole are connected in sequence to form a water channel 233. This arrangement allows the outer diameter of the first guide cylinder 231 to match the aperture of the water inlet channel 121, ensuring smooth sliding of the first guide cylinder 231 within the water inlet channel 121. At the same time, because the outer diameter of the first connecting cylinder 232 is smaller than that of the first guide cylinder 231, the first connecting cylinder 232 is spaced apart from the channel wall of the water inlet channel 121. This reduces sliding friction of the first guide member 23 while also creating a gap between the first connecting cylinder 232 and the channel wall of the water inlet channel 121, facilitating the outflow of water from the water passage 233 and improving the smoothness of water flow from the water inlet channel 121 to the cleaning channel 131. Preferably, a plurality of side water holes are spaced apart along the circumference of the first connecting cylinder 232.

[0088] In one embodiment, the cleaning connector 100 further includes a water inlet connector 4, which is detachably connected to the water inlet end of the water inlet channel 121 and has a water inlet communication channel that communicates with the water inlet channel 121. The provision of the water inlet connector 4 reduces the overall size of the four-way connector 1 while allowing the appropriate length of the water inlet connector 4 to be designed according to the water inlet position, thereby adjusting the height of the water inlet port of the cleaning connector 100. This allows the cleaning connector 100 to be more compatible with integrated cookers 800 of different types and sizes, reducing the processing and use costs of the cleaning connector 100. Furthermore, this provision facilitates the installation and removal of the first valve core 2.

[0089] The water inlet connector 4 is partially inserted into the water inlet passage 121, and the end of the first elastic member 21 away from the first blocking member 22 abuts the water inlet connector 4. This allows the first valve core 2 to be installed into the water inlet passage 121 from the inlet end. The pressure exerted by the water inlet connector 4 on the first elastic member 21 ensures the initial compression of the first elastic member 21 and limits the first valve core 2 from falling out of the water inlet passage 121, thereby facilitating assembly and disassembly of the first valve core 2 and installation of the first elastic member 21.

[0090] In one embodiment, the water inlet connector 4 is threadedly connected to the water inlet pipe portion 12, so that the depth of the water inlet connector 4 inserted into the water inlet pipe portion 12 can be adjusted, and the initial length of the first elastic member 21 when the first valve core 2 is in the initial conduction state can be adjusted, so that the elastic force applied by the first elastic member 21 to the first blocking member 22 can be adjusted, thereby avoiding the first elastic member 21 being too large, resulting in a larger steam inlet pressure being required to push the first blocking member 22 to open the outlet of the steam channel 111.

[0091] The water inlet connector 4 includes a main pipe portion 42, the inner cavity of which forms a water inlet channel 41. The outer wall of one end of the main pipe portion 42 is provided with an external thread, and the inner wall of the water inlet channel 121 is provided with an internal thread. The internal and external threads cooperate to enable the main pipe portion 42 to be installed in the water inlet channel 121. The outer wall of the main pipe portion 42 is provided with a limiter protrusion 44 protruding outward. The limiter protrusion 44 can abut the end surface of the water inlet pipe portion 12 to limit the insertion depth of the water inlet connector 4 into the water inlet channel 121, thereby providing positioning and limiting for the installation of the water inlet connector 4 on the cross-connector 1.

[0092] In one embodiment, a barrier 6 is provided at the air inlet passage 141 or the air inlet, and the second valve core 3 is located between the steam passage 111 and the barrier 6. The barrier 6 prevents foreign matter from entering the air inlet passage 141 and thereby entering the cooking chamber through the steam passage 111, thereby contaminating the cooking chamber or clogging the air inlet passage 141. This ensures smooth air intake and reliable operation of the second valve core 3, while reducing the probability of contamination of the cooking chamber.

[0093] The air inlet of the air inlet channel 141 is open, and the second valve core 3 can be removed from the air inlet channel 141 through the air inlet, thereby improving the installation and removal convenience of the second valve core 3 within the four-way connector 1. To improve the convenience of the second valve core 3 blocking the connection between the steam channel 111 and the air inlet, in one embodiment, the cleaning connector 100 also includes an air inlet end cover 5. The air inlet end cover 5 is removably installed at the air inlet and has a vent hole 54 extending along the extension direction of the air inlet channel 141. The second valve core 3 can open the vent hole 54 in the air inlet conduction state, thereby sequentially connecting the vent hole 54, the air inlet channel 141, and the steam channel 111. The second valve core 3 blocks the vent hole 54 in the initial blocking state.

[0094] The setting of the air intake end cover 5 makes the aperture of the air vent 54 smaller than the aperture of the air inlet, so that the air vent 54 can be blocked by the abutment between the second valve core 3 and the end face of the air intake end cover 5, thereby preventing external air from entering the air intake channel 141; at the same time, by setting the aperture of the air vent 54 and the size of the second blocking member 32, the second valve core 3 can meet the requirement of blocking the air inlet while the outer peripheral wall of the second valve core 3 can be spaced apart from the channel wall of the air intake channel 141 to form a ventilation gap, thereby ensuring the smoothness of air intake and simplifying the structure of the second valve core 3; the setting of the air intake end cover 5 can prevent the second valve core 3 from detaching from the air intake channel 141, thereby ensuring the stability and reliability of the setting of the second valve core 3 in the air intake channel 141; furthermore, the air intake end cover 5 is detachably connected to the four-way joint 1, which is also conducive to realizing the convenience of disassembly and assembly of the second valve core 3 in the air intake channel 141.

[0095] In one embodiment, the barrier member 6 is removably mounted on the air intake vent, thereby improving the ease of installation of the barrier member 6. To facilitate installation of the barrier member 6, the vent 54 includes a large hole portion 541 and a small hole portion 542. The large hole portion 541 has a larger diameter than the small hole portion 542, and the small hole portion 542 communicates with the side of the large hole portion 541 facing the air intake passage 141. The second valve core 3 can block the air outlet of the small hole portion 542, and the barrier member 6 is installed in the large hole portion 541. The provision of the large hole portion 541 and the small hole portion 542 facilitates the installation and positioning of the barrier member 6 on the air intake end cover 5, improving the ease of installation of the barrier member 6.

[0096] The size of the barrier 6 is preferably compatible with the size of the large hole 541 to prevent the barrier 6 from protruding from the air inlet cover 5 and causing scratches to the user, while also ensuring the stability of the barrier 6 within the large hole 541. In one embodiment, the barrier 6 is a grille structure to prevent foreign matter from entering the air inlet passage 141. In other embodiments, the barrier 6 may also be a filter structure.

[0097] To facilitate connection between the intake end cover 5 and the intake pipe 14, the intake end cover 5 includes a coaxially connected mounting portion 51 and a screwing portion 52. The mounting portion 51 is mounted within the intake passage 141, while the screwing portion 52 is located outside the intake passage 141. The cross-sectional area of the screwing portion 52 is larger than that of the mounting portion 51. This facilitates the formation of a large hole 541 on the screwing portion 52 while limiting the depth of insertion of the mounting portion 51 into the intake passage 141, thereby achieving connection and positioning between the intake end cover 5 and the intake pipe 14. Furthermore, a positioning portion 53 is connected between the mounting portion 51 and the screwing portion 52. The outer diameter of the positioning portion 53 is larger than that of the mounting portion 51. The positioning portion 53 abuts against the end surface of the intake pipe 14 to limit the insertion depth of the intake end cover 5 into the intake passage 141.

[0098] In one embodiment, the outer wall of the mounting portion 51 is provided with an external thread, and the inner wall of the intake pipe portion 14 is provided with an internal thread, and the mounting portion 51 is screwed into the intake pipe portion 14 to improve the installation stability and reliability of the intake end cover 5 on the intake pipe portion 14; in other embodiments, the intake end cover 5 can also be connected to the intake pipe portion 14 by screws or a clamping structure.

[0099] In one embodiment, the second valve core 3 includes a second elastic member 31 and a second blocking member 32. The second blocking member 32 is slidably mounted in the air inlet passage 141 along the extending direction of the air inlet passage 141. The second elastic member 31 is located on a side of the second blocking member 32 away from the air inlet. The second elastic member 31 constantly applies an elastic force to the second blocking member 32, forcing the second blocking member 32 to move toward the air inlet to block the vent 54. Specifically, by providing the second elastic member 31, when there is no negative pressure or a low negative pressure in the steam passage 111, the second blocking member 32 can stably and reliably block the vent 54 under the pressure of the second elastic member 31, thereby preventing steam in the steam passage 111 from flowing out through the air inlet passage 141.

[0100] The outer diameter of the second blocking member 32 is smaller than the aperture of the air inlet passage 141, creating a gap between the second blocking member 32 and the wall of the air inlet passage 141. This allows airflow entering through the air vent 54 when the second blocking member 32 opens, allowing airflow to flow downstream through the gap between the second blocking member 32 and the wall of the air inlet passage 141, simplifying the structure of the second blocking member 32. In other embodiments, the outer diameter of the second blocking member 32 can be equal to the inner diameter of the air inlet passage 141, and a groove can be defined on the outer wall of the second blocking member 32. The groove walls, together with the wall of the groove, form a ventilation gap for airflow to flow downstream.

[0101] The second valve core 3 also includes a second guide member 33. The first end of the second guide member 33 slidably engages with the wall of the air inlet passage 141, and the second end of the second guide member 33 is connected to the second blocking member 32. A vent channel 333 is disposed within the second guide member 33. When the second valve core 3 is in the air intake conduction state, external air flows sequentially through the vent hole 54, the gap between the second blocking member 32 and the wall of the air inlet passage 141, and the vent channel 333 into the steam passage 111. This ensures that the second blocking member 32 is slidably guided while preventing the second guide member 33 from interfering with the air intake of the steam passage 111.

[0102] In one embodiment, the second guide member 33 includes a second guide cylinder portion 331 and a second connecting cylinder portion 332. The outer diameter of the second guide cylinder portion 331 is larger than the outer diameter of the second connecting cylinder portion 332. The second guide cylinder portion 331 slides with the channel wall of the air intake channel 141. The outer side wall of the second connecting cylinder portion 332 is spaced apart from the channel wall of the air intake channel 141. The second connecting cylinder portion 332 is connected between the bottom of the second guide cylinder portion 331 and the second blocking member 32. The bottom of the second guide cylinder portion 331 is provided with a bottom air vent that connects the inner cavity of the second connecting cylinder portion 332 and the inner cavity of the second guide cylinder portion 331. The side wall of the second connecting cylinder portion 332 is provided with a side air vent.

[0103] The second elastic member 31 is at least partially located within the second guide cylinder portion 331, with one end abutting the bottom of the second guide cylinder portion 331 to facilitate installation of the second elastic member 31. A positioning step surface is defined within the air inlet passage 141, facing the air inlet. The second end of the second elastic member 31 abuts the positioning step surface, ensuring that the second elastic member 31 is positioned properly through the engagement of the positioning step surface with the second guide cylinder portion 331.

[0104] In one embodiment, an air intake connecting portion 15 is provided between the air intake pipe portion 14 and the steam pipe portion 11. The air intake connecting portion 15 has a connecting port 151 that connects the air intake passage 141 and the steam passage 111. The inner diameter of the connecting port 151 is smaller than the inner diameter of the air intake passage 141, thereby forming a positioning step surface at the connection point between the connecting port 151 and the air intake passage 141. In other embodiments, an annular positioning protrusion may be provided within the channel wall of the air intake passage 141, with one end surface of the positioning protrusion forming the positioning step surface. Furthermore, the outer diameter of the air intake connecting portion 15 is smaller than the outer diameter of the steam pipe portion 11.

[0105] like Figure 3 、 Figure 9 and Figure 10 As shown, to improve the connection convenience between the cleaning connector 100 and the volute assembly 201, in one embodiment, the cleaning device further includes a connecting pipe 300, one end of which is connected to the cleaning connector 100, and the other end of which is connected to the volute assembly 201. The inner cavity of the connecting pipe 300 communicates with the cleaning passage 131 and the air cavity of the volute assembly 201. By providing the connecting pipe 300, the size and specific structure of the connecting pipe 300 can be set according to the installation position of the air inlet passage 141 and the volute assembly 201. This allows the cleaning device to be better adapted to volute assemblies 201 installed in different positions while achieving the structural versatility of the cleaning connector 100, thereby improving the use flexibility of the cleaning device and reducing the use cost of the cleaning device.

[0106] In one embodiment, the connecting pipe 300 includes a main body 301 and a connecting joint 302. The connecting joint 302 can be detachably installed on the volute of the volute assembly 201, and the inner cavity of the connecting joint 302 is connected to the wind cavity. The main body 301 is connected between the connecting joint 302 and the cleaning pipe portion 13 of the cleaning joint 100. The main pipe portion 42 is preferably a hose, so that the connecting joint 302 can be pre-installed on the volute of the volute assembly 201, and then a main body 301 of appropriate size is selected according to the relative position of the connecting joint 302 and the cleaning pipe portion 13, and the installation position of the main body 301 is arranged to avoid interference between the connecting pipe 300 and other structures on the integrated stove, thereby improving the convenience of setting up the cleaning device.

[0107] Furthermore, the connection joint 302 includes a connection pipe portion and a mounting plate portion 3021 . The mounting plate portion 3021 protrudes radially outward from the connection pipe portion. The mounting plate portion 3021 is detachably connected to the volute. The connection pipe portion is detachably connected to the main body 301 .

[0108] In one embodiment, the volute assembly 201 is horizontally arranged on the upper side of the steamer 700, that is, the impeller shaft of the volute assembly 201 is vertically arranged, and the cleaning connector 100 is installed on the upper end surface of the volute of the volute assembly 201. In another embodiment, the volute assembly 201 can also be vertically arranged on the rear side of the steamer 700. In another embodiment, the volute assembly 201 is horizontally arranged on the lower side of the steamer 700. The arrangement of the volute assembly 201 in the integrated stove and the relative position relationship between the volute assembly 201 and the steamer 700 can be set with reference to the existing technology. This is not the focus of the present invention, and the present invention does not limit or elaborate on this. It is only necessary to ensure that the connecting pipe 300 is reasonably sized according to the position of the cleaning pipe portion 13 and the volute assembly 201.

[0109] To facilitate installation of the cleaning connector 100 within the integrated stove, it is located on the exterior of one side of the volute assembly 201 in the left-right direction, preventing interference between the cleaning connector 100 and the steamer 700. Furthermore, the cleaning connector 100 is primarily located outside the bellows 202, while the connecting pipe 300 is at least partially located inside the bellows 202, further facilitating installation of the cleaning connector 100 within the cabinet 900. To further enhance installation convenience of the cleaning connector 100 and the connecting pipe 300, the cleaning pipe portion 13 and the main pipe portion 42 of the connecting pipe 300 are sealed and removable.

[0110] In one embodiment, a limiting protrusion ring 16 is provided on the wall of the cleaning pipe portion 13, and the water outlet end of the cleaning pipe portion 13 passes through the bellows 202 and is connected to the connecting pipe 300. The limiting protrusion ring 16 abuts against the outer wall of the bellows 202, thereby limiting the insertion of the cleaning pipe portion 13 into the interior of the bellows 202, thereby improving the installation convenience and reliability of the cleaning connector 100.

[0111] In one embodiment, the air inlet passage 141 extends in the left-right direction away from the volute assembly 201, thereby increasing the distance between the air inlet and the volute assembly 201 and further reducing the probability of oil smoke backflowing into the cooking chamber through the air inlet. Furthermore, the cabinet 900 is provided with an air duct mounting cavity, in which the air duct assembly 200 is mounted, the cleaning connector 100 is mounted, and the air inlet end cover 5 is arranged to extend outside the air duct mounting cavity.

[0112] To collect wastewater after cleaning, an oil collection assembly 500 is installed in the integrated stove. In one embodiment, the oil collection assembly 500 includes an oil receiving pan 501 disposed below the volute assembly 201, an oil cup 503 mounted at the bottom of the integrated stove, and an oil guide pipe 502 connected between the oil receiving pan 501 and the oil cup 503. The oil receiving pan 501 has an open oil receiving trough 5011. The bottom of the volute assembly 201 is provided with an oil leakage port. The bottom of the bellows 202 has an oil collecting trough, and the oil leakage port is directly opposite the upper side of the oil collecting trough. The oil receiving pan 501 is located below the bellows 202, and an oil drain port is provided at the lowest point of the oil collecting trough, which is connected to the oil collecting trough. The oil guide pipe 502 is connected between the lowest point of the oil receiving trough 5011 and the oil cup 503 to guide the oil in the oil receiving trough 5011 into the oil cup 503.

[0113] It is understood that the drainage path for cleaning wastewater is the oil collection path for the oil inside the volute assembly 201, thereby eliminating the need for additional wastewater collection structures and simplifying the structure of the integrated stove. In other embodiments, when the volute assembly 201 is positioned near the bottom of the integrated stove, the oil pan 501 can be positioned directly above the oil cup 503, with an oil collection port defined at the lowest point of the oil receiving groove 5011, facing the oil cup 503, eliminating the need for the oil guide pipe 502.

[0114] like Figures 10 to 12 As shown, to improve the installation convenience of the cleaning connector 100 inside the integrated stove, in one embodiment, a support frame 1000 is provided inside the cabinet 900. The water inlet connector 4 is inserted through the support frame 1000, and the four-way connector 1 is located below the support frame 1000. The outer wall of the water inlet connector 4 is provided with a support protrusion 43 protruding outward, and the support protrusion 43 is supported by the support frame 1000. In this way, the support frame 1000 and the support protrusion 43 can cooperate to achieve stable support of the water inlet connector 4 on the support frame 1000, preventing the water inlet connector 4 from moving downward or falling. At the same time, this arrangement also helps to ensure that the water inlet connector 4 is arranged vertically, thereby facilitating the supply of external cleaning water to the interior of the water inlet connector 4. Specifically, the outer wall of the main pipe portion 42 of the water inlet connector 4 is provided with a support protrusion 43, which is located between the water inlet pipe portion 12 and the limiting protrusion 44.

[0115] In order to improve the convenience of the user in supplying water to the water inlet connector 4, in one embodiment, the range hood head 600 has a smoke collecting hood 601 with an open front side and a front panel 602 detachably arranged at the open front side. The smoke collecting hood 601 and the front panel 602 together form a smoke collecting chamber, which is communicated with the air inlet of the volute assembly 201. The water inlet port of the cleaning connector 100 extends upward into the smoke collecting chamber, and the water inlet port is communicated with the water inlet channel 121. Therefore, when the user needs to manually clean the volute assembly 201, the front panel 602 of the range hood head 600 is removed, and the water inlet port of the cleaning connector 100 and the faucet can be connected through a water pipe to realize water supply to the cleaning connector 100. When the volute assembly 201 does not need to be manually cleaned, the cleaning connector 100 is hidden in the back side of the front panel 602, making the overall structure of the integrated stove more beautiful and easy to achieve daily cleaning of the exterior of the integrated stove.

[0116] In one embodiment, the upper end of the water inlet connector 4 is the water inlet port. In other embodiments, the water inlet connector 4 may not be provided, that is, the upper end of the water inlet pipe portion 12 is the water inlet port.

[0117] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0118] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
