[0037] The utility model will be further explained in detail in connection with the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the utility model, and not limited to the utility model. In addition, it should be noted that in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all the structures.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] This embodiment provides a cooking device that can simultaneously perform steam cooking and effectively manage the hot steam generated during or after cooking, thereby improving the safety and reliability of the cooking device. The cooking device can be, but is not limited to, an electric steam oven, a steam oven, or a microwave-steam-grill combination appliance with steam cooking capabilities.

[0042] like Figure 1 and Figure 2 As shown, the cooking equipment includes a main body, a steam cooking module, and a controller. The main body includes an inner pot 9 with an open front, a base 5 installed at the bottom of the inner pot 9, and a casing located on the outside of the inner pot 9. The steam cooking module includes a steam generator and a water tank 4. The water tank 4 is located at the front of the bottom of the inner pot 9 and is used to supply water to the steam generator. The steam generator heats the water and generates hot steam to provide hot steam to the inner pot 9, thereby using the hot steam to cook the food inside the inner pot 9. The controller is communicatively connected to the steam generator to control the operation of the steam cooking module.

[0043] The steam cooking module also includes a water inlet pipe 20 and a water pump 10. One end of the water inlet pipe 20 is connected to the inner cavity of the water tank 4, and the other end of the water inlet pipe 20 is connected to the water inlet of the steam generator. The water pump 10 is installed on the water inlet pipe 20 to pump water from the water tank 4 into the steam generator.

[0044] It is worth noting that the structure of the main body, steam generator, water tank 4 and water inlet pipe 20, and controller can be designed with reference to existing technology. This is not the focus of this utility model, and this embodiment will not limit or elaborate on it. Among them, the steam generator can be a steam generator set on the outside of the inner pot 9, and the steam generated by the steam generator is introduced into the cooking cavity of the inner pot 9 through the pipeline; the steam generator can also be set on the heating plate at the bottom of the inner pot 9.

[0045] The cooking equipment also includes a steam condensation assembly, which is located on the outside of the inner liner 9 and is used to condense and cool the hot steam discharged from the inner liner 9. Specifically, the steam condensation assembly includes a condenser pipe 1, a water collection box 2, and a balance air pipe 3. The water collection box 2 has a water collection cavity. The air inlet end of the condenser pipe 1 is connected to the inner liner 9, and the air outlet end of the condenser pipe 1 is connected to the water collection cavity. A balance air hole is opened at the upper part of the water collection cavity and is connected to the water collection cavity. The air inlet end of the balance air pipe 3 is connected to the balance air hole, and the air outlet end of the balance air pipe 3 is connected to the inner cavity of the water tank 4.

[0046] The cooking equipment provided in this embodiment connects a balance gas pipe 3 to the water collection box 2 and connects the gas outlet of the balance gas pipe 3 to the inner cavity of the water tank 4. This allows the incompletely liquefied steam flowing from the condenser pipe 1 to flow through the balance gas hole to the balance gas pipe 3, and then through the balance gas pipe 3 to the water tank 4. This avoids the safety hazards and cleaning inconvenience caused by the steam escaping in the space between the inner liner 9 and the outer shell. At the same time, by setting up the balance gas pipe 3, the steam flow path can be extended, thereby enhancing the steam condensation effect, further reducing the amount of steam emitted, and improving the user experience of the cooking equipment. Furthermore, since the balance gas pipe 3 is connected to the inner cavity of the water tank 4, the existing cooking equipment's water tank 4 can be used to collect and discharge the condensate and steam flowing from the balance gas pipe 3, reducing the improvement cost of the cooking equipment and improving the structural compactness.

[0047] In this embodiment, the condenser pipe 1 and the water collection box 2 are located on the rear side of the inner liner 9, thereby making the main structure of the steam condensation assembly located on the rear side of the inner liner 9, reducing the space occupied by the steam condensation assembly on the left and right sides of the inner liner 9, thereby reducing the size of the cooking equipment in the left and right direction and improving the layout rationality of the steam condensation assembly.

[0048] To improve the condensation effect on condensate, in this embodiment, the steam condensation assembly further includes a radiator 6 and a fan assembly 7. The radiator 6 includes multiple heat dissipation fins arranged side-by-side and spaced apart, forming a vertically continuous heat dissipation channel between the fins. The condenser pipe 1 includes multiple condensation sections connected from top to bottom via bends, each condensation section passing through all the heat dissipation fins. The fan assembly 7 is arranged side-by-side with the radiator 6 in the left-right direction, with the radiator 6 located at the air outlet of the fan assembly 7. The fan assembly 7 guides external cooling airflow toward the radiator 6 to condense and dissipate heat from the radiator 6 and the condenser pipe 1, ensuring the condensation effect of the condenser pipe 1 on steam. In other embodiments, the condenser pipe 1 can be arranged vertically or in other arrangements.

[0049] Exemplarily, the fan assembly 7 includes a fan shroud 72, an impeller 73, and a drive motor 71. The fan shroud 72 has a fluid-connected air inlet, air cavity, and air outlet. The impeller 73 is installed inside the air cavity. The drive motor 71 is installed at the fan shroud 72 to drive the impeller 73 to rotate, so that the rotation of the impeller 73 drives the external cooling airflow to flow sequentially through the air inlet, air cavity, and air outlet to the radiator 6. It is worth noting that the condenser pipe 1, radiator 6, and fan assembly 7 can adopt the configuration of the prior art, which is not the focus of this utility model, and this utility model does not limit or elaborate on it.

[0050] In the left-right direction, the water collection box 2 is located on one side of the inner liner 9 along the left-right direction, and the outlet end of the balancing air pipe 3 is located on the other side of the inner liner 9 along the left-right direction. This increases the distance between the inlet and outlet ends of the balancing air pipe 3 in the left-right direction, thereby extending the length of the balancing air pipe 3 and enhancing the condensation effect of the balancing air pipe 3 on steam without changing the size of the inner liner 9.

[0051] like Figures 1-3 As shown, the balancing air pipe 3 includes a horizontal pipe section 31 extending in the left-right direction and a vertical pipe section 32 extending in the front-back direction. The front end of the vertical pipe section 32 is connected to the water tank 4, and the rear end is connected to the first end of the horizontal pipe section 31. The second end of the horizontal pipe section 31 is connected to the water collection box 2, and the other end is connected to the rear end of the horizontal pipe section 31. This can further increase the length of the balancing air pipe 3, and also improve the layout regularity of the balancing air pipe 3 in the cooking equipment, and reduce the probability of interference between the balancing air pipe 3 and other structures on the base 5.

[0052] Furthermore, the horizontal pipe section 31 is positioned higher than the vertical pipe section 32 and the water tank 4, so that the position of the air inlet end of the horizontal pipe section 31 is adapted to the upper position of the water collection box 2, while the height of the vertical pipe section 32 is adapted to the height of the water tank 4, and the vertical pipe section 33 and the horizontal pipe section 31 are connected by the vertically extending vertical pipe section 33.

[0053] Optionally, the longitudinal tube 32 extends downward at an angle from back to front, and / or the transverse tube 31 extends downward at an angle from the second end to the first end, thereby facilitating the flow of condensate in the balance air tube 3 into the water tank 4.

[0054] To further enhance the condensation effect of the balancing air pipe 3, an auxiliary condensation structure may be provided on the outside of the balancing air pipe 3. The auxiliary condensation structure may be, but is not limited to, heat dissipation fins, thermally conductive coatings, or other structures.

[0055] The water collection box 2 includes a box body and an exhaust pipe protruding from one side of the box body. The inner cavity of the box body forms a water collection chamber. The upper end of the box body is connected to the lower end of the condenser pipe 1. A balance vent is provided on one side of the upper part of the box body. The exhaust pipe is provided corresponding to the balance vent, and the balance pipe 3 is sealed and inserted into the exhaust pipe. The exhaust pipe extends laterally, thereby achieving upper exhaust while facilitating the sealed connection between the balance pipe 3 and the water tank 4.

[0056] Specifically, in this embodiment, the air inlet end of the balancing air pipe 3 has an air inlet connector 34, which is connected to the air inlet end of the horizontal pipe section 31. The inner diameter of the air inlet connector 34 is larger than the inner diameter of the main structure of the balancing air pipe 3, that is, the inner diameter of the air inlet connector 34 is larger than the inner diameter of the horizontal pipe section 31, so that a positioning step surface is formed between the air inlet connector 34 and the horizontal pipe section 31. The air outlet section is sealed and inserted into the air inlet connector 34, thereby improving the assembly efficiency and assembly accuracy of the balancing air pipe 3 and the water collection box 2, and helping to ensure the sealing performance after assembly. In other embodiments, the balancing air pipe 3 may also be sealed and inserted inside the water collection box 2, or the balancing air pipe 3 may be sealed and inserted into the air outlet section.

[0057] The base 5 has a front-opening mounting groove at its front end, allowing the water tank 4 to be pulled out and placed in the mounting groove, facilitating the addition and pouring of water. Furthermore, the base 5 includes a base frame 52 and a tank seat 51 located on the front side of the base frame 52. The base frame 52 and the tank seat 51 together form the front-opening mounting groove, and the base frame 52 and the tank seat 51 are detachably connected to reduce the processing difficulty of the base 5.

[0058] The front end of the base frame 52 is folded upward to form a front plate portion 521, and the upper end of the front plate portion 521 is folded forward to form a top plate portion 522. A housing 51 is located on the front side of the front plate portion 521 and below the top plate portion 522. The top plate portion 522 and the housing 51 together form a mounting groove. The housing 51 is detachably connected to the front plate portion 521 and the top plate portion 522. The detachable connection method can be, but is not limited to, snap-fit ​​or screw connection. Further, the housing 51 includes a lower seat plate portion 511 and a rear seat plate portion 512 connected vertically. The lower seat plate portion 511 and the top plate portion 522 form the upper and lower side walls of the mounting groove. The rear seat plate portion 512 is located on the front side of the front plate portion 521 and forms the rear side wall of the mounting groove. The rear seat plate portion 512 is detachably connected to the front plate portion 521.

[0059] It is worth noting that the connection structure between the box base 51 and the base 5, as well as the specific structure of the base 5, can be set with reference to the existing technology. This is not the focus of this utility model and will not be elaborated here.

[0060] In this embodiment, a vent hole 5133 is provided through the rear wall of the mounting groove. The balancing air pipe 3 is installed on the base 5 and communicates with the vent hole 5133. An air inlet 4141 is provided on the rear side of the water tank 4. When the water tank 4 is installed in the mounting groove, the air inlet 4141 and the vent hole 5133 are directly opposite and communicate with each other. By connecting the balancing air pipe 3 to the base 5, the balancing air pipe 3 will not be affected when the water tank 4 is pulled out, ensuring the stability of the balancing air pipe 3 and also ensuring the convenience of taking the water tank 4 out and putting it in. Specifically, a vent hole 5133 is provided on the rear side of the tank base 51.

[0061] In this embodiment, a connector 513 protrudes rearward from the rear side of the housing 51. The inner cavity of the connector 513 forms a vent hole 5133. The connector 513 is sealed and inserted into the balance air pipe 3 to improve the assembly efficiency of the cooking equipment and the installation efficiency of the balance air pipe 3. Specifically, the outlet end of the balance air pipe 3 is flared to form an outlet connector 35. The connector 513 is sealed and inserted into the outlet connector 35. The connector 513 can be press-fitted with the outlet connector 35, or the connector 513 and the outlet connector 35 can be sealed by a sealing ring.

[0062] like Figures 3 to 5 As shown, in this embodiment, the inner cavity of the water tank 4 includes a water supply cavity 421 and an exhaust cavity 411 separated from each other. The cavity wall of the exhaust cavity 411 has an exhaust hole 4321. The exhaust end of the balancing air pipe 3 is connected to the exhaust cavity 411. The water supply cavity 421 is used to contain water for the steam generator. By setting the water supply cavity 421 and the exhaust cavity 411, the water supply and the exhaust of the balancing air pipe 3 are separated, thereby preventing water in the water tank 4 from flowing back into the balancing air pipe 3 and affecting the normal exhaust process.

[0063] The water supply chamber 421 and the venting chamber 411 are arranged side by side in the left-right direction, and the length of the water supply chamber 421 is greater than the length of the venting chamber 411, so as to reduce the impact of the arrangement of the venting chamber 411 on the water supply volume of the water tank 4. Furthermore, the length of the water supply chamber 421 in the left-right direction is at least five times the length of the venting chamber 411 in the left-right direction.

[0064] Optionally, an auxiliary condensation structure is provided inside the exhaust chamber 411 to further condense the steam entering the exhaust chamber 411. The auxiliary condensation structure may be, but is not limited to, a metal layer structure, etc.

[0065] To improve the ease of installation of the water tank 4, the water tank 4 includes a tank body with an open top and a cover 43 covering the tank body. The cover 43 covers the open top of the tank body and has a vent 4321. The cover 43 is spaced apart from the upper wall of the mounting groove. This allows gas entering the vent chamber 411 to escape through the vent 4321, preventing excessive pressure inside the vent chamber 411. At the same time, the upward-flowing steam can partially contact the upper wall of the mounting groove for further condensation and cooling. Specifically, the cover 43 covers the open top of the water supply chamber 421 and the vent chamber 411, and has a vent 4321 above the vent chamber 411.

[0066] In another embodiment, an exhaust hole 4321 may be provided on the front wall of the exhaust chamber 411 or on the side wall of the exhaust chamber 411 away from the water supply chamber 421. In yet another embodiment, the gap between the tank cover 43 and the tank body may form an exhaust gap.

[0067] Furthermore, the tank cover 43 includes a separate vent cover 432 and a main cover 431. The main cover 431 covers the upper side of the water supply chamber 421, and the vent cover 432 covers the upper side of the vent chamber 411. The vent cover 432 is provided with a vent hole 4321, thereby reducing the processing difficulty and cost of the tank cover 43. In other embodiments, the tank cover 43 can also be integrally formed.

[0068] In this embodiment, the tank includes an outer casing 41 and an inner casing 42. The outer casing 41 has an inner cavity with an opening at the top. A partition 413 is provided inside the inner cavity, dividing it into an exhaust chamber 411 and a receiving chamber 412. The inner casing 42 is removably disposed in the receiving chamber 412, and the inner cavity of the inner casing 42 forms a water supply chamber 421. By placing the exhaust chamber 411 on the outer casing 41, the inner casing 42 can adopt the structure of the existing inner casing 42 in the water tank 4, and the mating structure between the inner casing 42 and the water inlet pipe 20 can be consistent with the existing structure, making the inner casing 42 universal and reducing the improvement cost of the water tank 4.

[0069] It is worth noting that the specific structure of the inner box 42, the connection structure between the inner box 42 and the water inlet pipe 20, and the matching structure between the inner box 42 and the outer box 41 can all be set with reference to the existing technology. This is not the focus of the improvement of this utility model, and this embodiment does not limit or elaborate on it.

[0070] A connecting pipe portion 414 protrudes outward from the rear wall of the outer casing 41. The inner cavity of the connecting pipe portion 414 forms an air inlet 4141. The connecting pipe portion 414 is inserted into and pulled into the vent 5133 to facilitate the fit between the outer casing 41 and the casing base 51, improve the reliability of the fit, and thus ensure the reliability of the exhaust of the balance air pipe 3. Further, the insertion pipe portion 513 includes a first pipe portion 5131 and a second pipe portion 5132 coaxially connected. The inner diameter of the first pipe portion 5131 is larger than the inner diameter of the second pipe portion 5132. The first pipe portion 5131 is connected to the rear seat plate portion 512, the second pipe portion 5132 is inserted into the air outlet connector 35, and the first pipe portion 5131 is inserted into the connecting pipe portion 414.

[0071] Preferably, a sealing ring is fitted on the outer side of the connecting pipe portion 414 to seal the gap between the outer wall of the connecting pipe portion 414 and the inner wall of the first pipe portion 5131, thereby achieving an exhaust seal. Specifically, an annular groove is formed on the outer wall of the connecting pipe portion 414, and the sealing ring is installed in the annular groove and protrudes from the outer wall of the connecting pipe portion 414 to facilitate the installation of the sealing ring and prevent the sealing ring from falling out of the connecting pipe portion 414.

[0072] like Figure 3 and Figure 6 As shown, in this embodiment, a sealing component 44 is installed on the water tank 4. The sealing component 44 can block the air inlet 4141 when the water tank 4 moves forward relative to the base 5, and open the air inlet 4141 when the water tank 4 is assembled in the mounting slot. By setting the sealing component 44, it is possible to better prevent water in the water tank 4 from overflowing out through the air inlet 4141 when the water tank 4 is pulled out.

[0073] Specifically, the sealing assembly 44 includes a sealing element and an elastic element 443. The sealing element is slidably disposed in the air inlet 4141 and has a sealed position for sealing the air inlet 4141 and an open position for opening the air inlet 4141. The elastic element 443 is used to apply a rearward elastic force to the sealing element so that the sealing element is held or returns to the sealed position. A pushing member 514 is provided in the vent 5133. The pushing member 514 can push the sealing element to slide forward relative to the outer casing 41 when the water tank 4 is inserted into the mounting slot, so that the sealing element is in the open position. This structure of the sealing assembly 44 allows the sealing assembly 44 to automatically operate so that the sealing element seals the air inlet 4141 when the outer casing 41 is pulled out forward, and the sealing element moves to the open position when the outer casing 41 is inserted into the mounting slot backward, realizing automatic switching of the state of the sealing assembly 44 without additional operation, and the cost of the purely mechanical structure is low.

[0074] The sealing component includes a slide rod 441 and a sealing head 442. The slide rod 441 is slidably inserted into the air inlet 4141 and its front end is located in the exhaust chamber 411. The sealing head 442 is fitted onto the front end of the slide rod 441 and can block the front opening of the air inlet 4141, thereby improving the ease of setting the sealing component.

[0075] In this embodiment, the sealing head 442 and the sliding rod 441 are detachably connected. The sealing head 442 is preferably made of an elastic material such as rubber or silicone, and the sliding rod 441 is preferably made of metal or hard plastic. In other embodiments, the sliding rod 441 and the sealing head 442 can be integrally formed.

[0076] The air inlet 4141 includes a large hole and a small hole that communicate with each other. The large hole is located at the rear end of the small hole and its diameter is larger than that of the small hole. A limiting step surface is formed between the large hole and the small hole. A limiting protrusion 4412 protrudes from the rear end of the slide rod 441. An elastic member 443 is sleeved on the slide rod 441 and its two ends abut against the limiting step surface and the limiting protrusion 4412, respectively. The rear end of the slide rod 441 is restricted from passing through the small hole to prevent the slide rod 441 from dislodging forward from the air inlet 4141.

[0077] The slide bar 441 includes a main body 4411, with a limiting protrusion 4412 protruding from the rear end of the main body 4411. The cross-section of the main body 4411 can be, but is not limited to, a cross shape, a quincunx shape, or other non-circular shapes, to reduce the impact of the slide bar 441's arrangement on the smoothness of exhaust. The slide bar 441 also includes a mounting shaft 4413 connected to the front end of the main body 4411, with a sealing head 442 sleeved on the mounting shaft 4413. The mounting shaft 4413 has a circular cross-section to facilitate installation and mating with the sealing head 442.

[0078] Furthermore, an annular groove is provided on the mounting shaft 4413, and the sealing head 442 is installed in the annular groove to prevent the sealing head 442 from moving axially along the mounting shaft 4413. The front end of the mounting shaft 4413 is truncated into a frustum structure to facilitate the guidance of the sealing head 442 as it is fitted into the mounting shaft 4413.

[0079] Furthermore, the second tube 5132 is provided with a pushing member 514 inside, the front end of which extends into the first tube 5131 to push against the rear end of the slide rod 441. The pushing member 514 can be integrally formed with the first tube 5131, or it can be welded or detachably installed inside the first tube 5131.

[0080] In this embodiment, the pushing member 514 has a V-shaped structure, and both ends of the V-shaped structure abut against the inner wall of the second pipe 5132, so as to enhance the structural strength and rigidity of the pushing member 514 while reducing the increase in exhaust resistance caused by the setting of the pushing member 514. However, it is understood that the pushing member 514 can also adopt other structural forms, as long as it can be inserted into the water tank 4 to push the sealing member forward.

[0081] like Figure 2 and Figure 5 As shown, in this embodiment, the water tank 4 supplies water to the steam generator of the cooking equipment through the water inlet pipe 20. The bottom of the water collection box 2 has a drain outlet connected to a drain pipe 8. The outlet of the drain pipe 8 is connected to the water inlet pipe 20, thereby allowing the condensate in the water collection chamber to be recycled, saving water resources, and eliminating the need to disassemble the water collection box 2. A drain control valve is installed on the drain pipe 8 to control the timing of condensate discharge from the water collection box 2.

[0082] In another embodiment, the outlet end of the drain pipe 8 is connected to the water supply chamber 421. In yet another embodiment, a wastewater chamber, separated from the water supply chamber 421, is provided in the inner tank 42, and the outlet end of the drain pipe 8 is connected to the wastewater chamber. In yet another embodiment, the downstream section of the balancing air pipe 3 is connected, thereby allowing condensate to flow into the water tank 4 through the balancing air pipe 3.
