Description

Technical Field

[0001] The present invention relates to the technical field of food cooking, and more specifically, to a double-channel exhaust steam-steaming oven. Background Art

[0002] A steam frying oven is a cooking appliance that has the functions of pure steaming, baking, and tender baking (i.e., steaming and baking mixed). For example, a steam oven disclosed in the prior art includes an outer shell, an inner pot, a condensing assembly, and a heating component. The inner pot is located in the outer shell, and a steam outlet is provided on the inner pot. The condensing assembly is located in the outer shell, and the condensing assembly has a condensing cavity connected to the steam outlet; an air outlet is provided on the top of the condensing assembly, and the condensing cavity is connected to the outside through the air outlet. The heating component is located in the outer shell, and the heating component is provided on the condensing assembly.

[0003] Due to cooking needs, the pure steaming function requires a smaller steam outlet, otherwise there will be a large amount of exhaust steam, resulting in more condensed water discharge, and will reduce the efficiency of pure steaming or steam-baking. The baking function requires a larger steam outlet so that the smoke, steam and odor generated during the baking process can be discharged in time, otherwise it will affect the cooking effect. As for the tender baking function, since moisture needs to be locked during the steaming and baking process, the steam outlet of the oven also needs to be smaller, otherwise it will also affect the cooking effect. However, if the steam outlet is too small, the inner cavity of the oven is prone to excessive pressure, which will lead to problems such as difficulty in closing the door and abnormal noise when closing the door during the cooking process. Since the above-mentioned prior art only provides one steam outlet, and the steam outlet opening cannot be adjusted, it is impossible to achieve a relatively good cooking effect for the pure steaming, baking and tender baking functions. Summary of the invention

[0004] In view of the problem that the above-mentioned prior art only has one steam outlet and the opening of the steam outlet cannot be adjusted, and the pure steaming, baking and tender baking functions cannot all achieve a relatively good cooking effect, the present invention provides a dual-channel exhaust steam oven, which can ensure that the pure steaming, baking and tender baking functions can all achieve a relatively good cooking effect.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] A dual-channel exhaust steam oven comprises a box body, a heating component, a first exhaust pipe and an exhaust seat; a cooking cavity and a first exhaust port are provided in the box body; the heating component is arranged in the cooking cavity; the exhaust seat is connected to the box body; the first exhaust port is connected to the exhaust seat through the first exhaust pipe; and a second exhaust pipe is also included, a second exhaust port is provided in the box body, the second exhaust port is connected to the exhaust seat through the second exhaust pipe, an opening adjustment mechanism is provided at the outlet end of the first exhaust pipe or the second exhaust pipe, and the opening adjustment mechanism is located in the exhaust seat.

[0007] In the above technical solution, in the first exhaust pipe and the second exhaust pipe, the outlet of one is always open, and the outlet end of the other can adjust the opening size through the opening adjustment mechanism, and the steam in the cooking cavity can enter the exhaust seat through the first exhaust pipe and / or the second exhaust pipe, and then be discharged to the external environment through the exhaust seat. When using the pure steaming function, the exhaust pipe with an outlet that is always open can discharge the excess steam generated during the steaming process, while the outlet of the other exhaust pipe is closed, which can avoid excessive steam discharge and ensure steaming efficiency; when the steam pressure is too high, the opening adjustment mechanism can adjust the outlet opening of the other exhaust pipe to keep the pressure of the cooking cavity stable and avoid difficulty in opening the door or abnormal noise when opening the door. When using the baking function, although steam is not needed, the exhaust pipe with an outlet that is always open can ensure the air flow inside the cooking cavity; when the pressure in the cooking cavity is too high, the opening adjustment mechanism can adjust the outlet opening of the other exhaust pipe to avoid smoke and odor staying in the cooking cavity. When using the tender baking function, the exhaust pipe with a normally open outlet can discharge excess steam, smoke and odor generated during the cooking process, preventing the food surface from being too wet and preventing smoke and odor from staying in the cooking chamber; when the pressure in the cooking chamber is too high, the opening adjustment mechanism can adjust the outlet opening of another exhaust pipe to adjust the amount of steam, smoke and odor discharged, ensuring that the outside of the food can achieve the ideal baking effect.

[0008] Preferably, the opening adjustment mechanism can be a sliding member slidably arranged at the outlet end of the first exhaust pipe or the second exhaust pipe, and the sliding member can slide along the axial direction of the outlet of the first exhaust pipe or the second exhaust pipe, or can slide along the perpendicular direction of the aforementioned direction. The sliding of the sliding member can be set to multiple gears, each gear corresponding to a different opening size, and the opening can be adjusted by manually sliding the sliding member to the corresponding gear according to actual needs.

[0009] Preferably, the opening adjustment mechanism includes a micro-pressure ball and an elastic member, a limiting guide rail is provided at the outlet end of the first exhaust pipe or the second exhaust pipe, the micro-pressure ball is slidably arranged in the limiting guide rail, one end of the elastic member is connected to the micro-pressure ball, and the other end is abutted against the inner wall of the exhaust seat. Assuming that the opening adjustment mechanism is arranged at the outlet end of the second exhaust pipe, when the pressure in the cooking cavity reaches a certain level, the micro-pressure ball can be pushed open and compress the elastic member, so that the outlet of the second exhaust pipe is exposed to a certain size, and the steam in the cooking cavity can enter the exhaust seat through the second exhaust pipe. As the pressure in the cooking cavity gradually increases, the distance moved by the micro-pressure ball gradually increases, and the size exposed by the outlet of the second exhaust pipe also gradually increases. Compared with structures of other shapes, the micro-pressure ball structure is simpler and can more tightly block the first exhaust pipe or the second exhaust pipe. In addition, during the exhaust process, the steam or gas encounters less resistance when passing through the surface of the micro-pressure ball, so there will be no problems of poor exhaust and high exhaust noise.

[0010] Preferably, the exhaust seat is provided with a condensation cavity and an exhaust through hole, and the heating component is at least partially located at the bottom of the cooking cavity. After the steam exhausted by the first exhaust pipe and the second exhaust pipe enters the condensation cavity, part of it contacts the inner wall of the condensation cavity and condenses into water, and the other part is discharged from the exhaust seat through the exhaust through hole. The condensed water in the condensation cavity can flow back into the cooking cavity through the first exhaust pipe or the second exhaust pipe with an outlet that is normally open to be heated by the heating component, thereby generating more steam, thereby realizing the condensation and reflux utilization of steam and reducing the amount of steam discharged.

[0011] Preferably, a plurality of first baffles are provided in the condensation chamber, and the first baffles are located between the outlet end of the first exhaust pipe or the second exhaust pipe and the exhaust through-hole; the first exhaust port and the second exhaust port are connected to the condensation chamber through the first exhaust pipe and the second exhaust pipe, respectively. After the steam enters the condensation chamber, it will flow in the direction of the exhaust through-hole, so the steam will also pass through the first baffle and condense into water on the surface of the first baffle. At the same time, the condensed water carried in the flowing steam will also be blocked by the first baffle. Providing a plurality of first baffles can improve the condensation efficiency of the steam and the recovery rate of the steam, and further reduce the amount of steam discharged.

[0012] Preferably, the first baffles are distributed in multiple rows, and the first baffles in two adjacent rows are staggered. Such a configuration can reduce the turbulence and stagnation of the steam flow, help the steam flow on the surface of the first baffles, reduce the dead zone of the steam flow, enable the steam to condense more evenly and completely, and can block more condensed water.

[0013] Preferably, a first inclined surface is provided in the condensing chamber, the first retaining rib and the limiting guide rail are both located on the first inclined surface, the first retaining rib, the outlet end of the second exhaust pipe, and the outlet end of the first exhaust pipe are sequentially arranged along the extension direction of the first inclined surface, and the position of the first retaining rib on the first inclined surface is higher than the position of the outlet end of the first exhaust pipe; the limiting guide rail is located at the outlet end of the second exhaust pipe, and a first channel is formed between the end of the limiting guide rail away from the outlet end of the second exhaust pipe and the inner wall of the condensing chamber. The first inclined surface can guide the flow of condensed water to the outlet end of the first exhaust pipe, reducing the residual condensed water in the condensing chamber.

[0014] Preferably, a water collecting tank is provided on the first inclined surface, and the water collecting tank is located at the outlet end of the first exhaust pipe. The condensed water on the first inclined surface first flows to the water collecting tank, and then flows into the outlet end of the first exhaust pipe through the water collecting tank. The water collecting tank can collect the condensed water in the condensation chamber to the water collecting tank and then flow into the first exhaust pipe together, further reducing the residual condensed water in the condensation chamber.

[0015] Preferably, a second baffle and a third baffle are further provided on the first inclined surface, and the limiting guide rail is located between the second baffle and the third baffle, and the second baffle and the third baffle respectively form a second channel and a third channel with the inner wall of the condensation chamber, and the second channel and the third channel are both located on the side opposite to the first channel. Part of the steam flowing out of the first exhaust pipe hits the surface of the third baffle and condenses into water, and the other part flows through the first channel through the third channel. Part of the steam flowing through the first channel hits the surface of the second baffle and condenses into water, and the other part flows to the first baffle through the second channel. The condensed water on the first inclined surface passes through the second channel, the first channel and the third channel in sequence, and finally flows to the water collecting tank. The provision of the second baffle and the third baffle can further improve the condensation efficiency of the steam.

[0016] Preferably, the elastic member adopts a spring structure. Compared with elastic material members, the elastic properties of the spring structure remain unchanged after multiple deformations and restorations, and the use is more reliable.

[0017] Preferably, the heating component includes a second heating tube, and both ends of the second heating tube are rotatably connected to opposite sides of the cooking cavity; a water storage tank is provided at the bottom of the cooking cavity, and at least part of the second heating tube is located in the water storage tank. Condensed water in the cooking cavity can be collected in the water storage tank for heating by the second heating tube, and the second heating tube can not only heat the condensed water to generate steam, but also be used to assist in heating food in the cooking cavity. Since the second heating tube is rotatable, the second heating tube can be rotated to facilitate cleaning of the water storage tank.

[0018] Beneficial effects of the present invention:

[0019] 1. A dual-channel exhaust structure is adopted, in which the outlet of one exhaust pipe is normally open, and the outlet opening size of the other exhaust pipe can be adjusted by the opening adjustment mechanism. This can not only avoid the problems of poor exhaust, difficulty in closing the door or abnormal door closing noise, but also enable the pure steaming, baking and tender baking functions in the cooking chamber to achieve relatively better cooking effects.

[0020] 2. The steam in the cooking cavity enters the condensation cavity of the exhaust seat and can be condensed into water. The condensed water can flow back into the cooking cavity through the first exhaust pipe to be heated to form steam, thereby forming a cycle of steam condensation and evaporation, which can reduce the amount of steam discharged.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Example 1

[0032] This embodiment is the first embodiment of a dual-channel exhaust steam oven. Figures 1 to 4As shown, it includes a box body 1, a heating component, a steam generator (not shown in the figure), a first exhaust pipe 3 and an exhaust seat 4; a cooking cavity 101 and a first exhaust port 102 are provided in the box body 1; the heating component includes a first heating tube 2 arranged on the top of the cooking cavity 101; the steam generator is connected to the box body 1 and the outlet end of the steam generator is connected to the cooking cavity 101; the exhaust seat 4 is connected to the box body 1; the first exhaust port 102 is connected to the exhaust seat 4 through the first exhaust pipe 3; and it also includes a second exhaust pipe 5, a second exhaust port 103 is provided in the box body 1, and the second exhaust port 103 is connected to the exhaust seat 4 through the second exhaust pipe 5, and an opening adjustment mechanism is provided at the outlet end of the second exhaust pipe 5, and the opening adjustment mechanism is located in the exhaust seat 4.

[0033] The opening adjustment mechanism may be a sliding member slidably arranged at the outlet end of the second exhaust pipe 5, and the sliding member may slide along the axial direction of the outlet of the second exhaust pipe 5, or may slide along the perpendicular direction of the aforementioned direction. The sliding of the sliding member may be set to a plurality of gears, each gear corresponding to a different opening size, and the opening may be adjusted by manually sliding the sliding member to a corresponding gear according to actual needs.

[0034] In this embodiment, the opening adjustment mechanism includes a micro-pressure ball 6 and an elastic member 7. A limiting guide rail 8 is provided at the outlet end of the second exhaust pipe 5. The micro-pressure ball 6 is slidably arranged in the limiting guide rail 8. One end of the elastic member 7 is connected to the micro-pressure ball 6, and the other end is in contact with the inner wall of the exhaust seat 4. Assuming that the opening adjustment mechanism is arranged at the outlet end of the second exhaust pipe 5, when the pressure in the cooking cavity 101 reaches a certain level, the micro-pressure ball 6 can be pushed open and compress the elastic member 7, so that the outlet of the second exhaust pipe 5 is exposed to a certain extent, and the steam in the cooking cavity 101 can enter the exhaust seat 4 through the second exhaust pipe 5. Compared with structures of other shapes, the micro-pressure ball 6 has a simpler structure and can more tightly block the outlet of the second exhaust pipe 5. In addition, during the exhaust process, the steam or gas encounters less resistance when passing through the surface of the micro-pressure ball 6, so there will be no problems of poor exhaust and high exhaust noise.

[0035] Specifically, the elastic member 7 adopts a spring structure. Compared with the elastic material member, the elastic performance of the spring structure remains unchanged after multiple deformations and restorations, and the use is more reliable.

[0036] The working principle or workflow of this embodiment is as follows: the outlet of the first steam exhaust pipe 3 is normally open, and the outlet of the second steam exhaust pipe 5 can adjust the opening size by an opening adjustment mechanism. The steam in the cooking cavity 101 can enter the steam exhaust seat 6 through the first steam exhaust pipe 3 and / or the second steam exhaust pipe 5, and then be discharged to the external environment through the steam exhaust seat 6. When the pure steaming function is used, the heat source in the cooking cavity 101 is the steam delivered by the steam generator, the first heating tube 2 does not work, and the first steam exhaust pipe 3 with an outlet that is normally open can exhaust the excess steam generated during the steaming process. Since the outlet of the second steam exhaust pipe 5 is closed by the micro-pressure round ball 6, excessive steam discharge can be avoided and the steaming efficiency can be guaranteed; when the steam pressure is too high, the micro-pressure round ball 6 can be pushed open and compress the elastic part 7, so that the outlet of the second steam exhaust pipe 5 is exposed to a certain extent, and the steam in the cooking cavity 101 can enter the steam exhaust seat 4 through the second steam exhaust pipe 5. As the pressure in the cooking cavity 101 gradually increases, the distance moved by the micro-pressure round ball 6 gradually increases, and the outlet opening of the second steam exhaust pipe 5 also gradually increases to keep the pressure in the cooking cavity 101 stable and avoid difficulty in opening the door or abnormal noise when opening the door. When the baking function is used, the heat source in the cooking cavity 101 comes only from the heat radiation of the first heating tube 2. Although the baking function does not require steam, the first steam exhaust pipe 3 with an outlet that is always open can ensure the air flow inside the cooking cavity 101. When the pressure in the cooking cavity 101 is too high, the micro-pressure round ball 6 can be moved to adjust the outlet opening of the second steam exhaust pipe 5 to prevent smoke and odor from staying in the cooking cavity. When the tender baking function is used, the heat source in the cooking cavity 101 is the steam delivered by the steam generator and the heat radiation of the first heating tube 2. The first steam exhaust pipe 3 with an outlet that is always open can discharge the excess steam, smoke and odor generated during the cooking process to prevent the food surface from being too wet and to prevent smoke and odor from staying in the cooking cavity 101. When the pressure in the cooking cavity 101 is too high, the micro-pressure round ball 6 can be moved to adjust the opening of the second steam exhaust pipe 5 to adjust the amount of steam, smoke and odor discharged to ensure that the food can achieve an ideal baking effect on the outside.

[0037] Beneficial effects of this embodiment:

[0038] 1. A dual-channel exhaust structure is adopted, in which the outlet of one exhaust pipe is normally open, and the outlet opening size of the other exhaust pipe can be adjusted by the opening adjustment mechanism. This can not only achieve relatively better cooking effects for pure steaming, baking and tender baking functions in the cooking chamber, but also avoid the problems of difficulty in closing the door and abnormal noise when closing the door due to poor exhaust.

[0039] 2. The steam in the cooking cavity enters the condensation cavity of the exhaust seat and can be condensed into water. The condensed water can flow back into the cooking cavity through the first exhaust pipe to be heated to form steam, thereby forming a cycle of steam condensation and evaporation, which can reduce the amount of steam discharged.

[0040] Example 2

[0041] This embodiment is a second embodiment of a dual-channel exhaust steam oven. This embodiment is similar to the embodiment, except that Figures 1 to 5 As shown, the exhaust seat 4 includes a seat body 401 and a top cover 402 detachably connected to the seat body 401, and a condensation chamber 403 is enclosed between the seat body 401 and the top cover 402; an exhaust through hole 404 is provided on the top cover 402; and a heating component is partially located at the bottom of the cooking chamber 101. After the steam exhausted by the first exhaust pipe 3 and the second exhaust pipe 5 enters the condensation chamber 403, part of it contacts the inner wall of the condensation chamber 403 and condenses into water, and the other part is discharged from the exhaust seat 4 through the exhaust through hole 404. The condensed water in the condensation chamber 403 can flow back to the cooking chamber 101 through the first exhaust pipe 3 with the outlet normally open to be heated by the heating component, thereby generating more steam, thereby realizing the condensation and reflux utilization of steam and reducing the amount of steam discharged.

[0042] Furthermore, a plurality of first baffles 9 are provided in the condensation chamber 403, and the first baffles 9 are located between the outlet ends of the first exhaust pipe 3 and the second exhaust pipe 5 and the exhaust through hole 404; the first exhaust port 102 and the second exhaust port 103 are connected to the condensation chamber 403 through the first exhaust pipe 3 and the second exhaust pipe 5, respectively. After the steam enters the condensation chamber 403, it will flow in the direction of the exhaust through hole 404, so the steam will also pass through the first baffle 9 and condense into water on the surface of the first baffle 9. At the same time, the condensed water carried by the flowing steam will also be blocked by the first baffle 9. The provision of a plurality of first baffles 9 can improve the condensation efficiency of the steam and the recovery rate of the steam, and further reduce the amount of steam discharged.

[0043] Furthermore, the first baffles 9 are distributed in multiple rows, and two adjacent rows of first baffles 9 are staggered. Such a setting can reduce the turbulence and stagnation of the steam flow, help the steam flow on the surface of the first baffles 9, reduce the dead zone of the steam flow, so that the steam can be condensed more evenly and more completely, and more condensed water can be blocked.

[0044] Furthermore, a first inclined surface 405 is provided in the condensation chamber 403, and the first retaining rib 9 and the limiting guide rail 8 are both located on the first inclined surface 405. The first retaining rib 9, the outlet end of the second exhaust pipe 5, and the outlet end of the first exhaust pipe 3 are sequentially arranged along the extension direction of the first inclined surface 405. The position of the first retaining rib 9 on the first inclined surface 405 is higher than the position of the outlet end of the first exhaust pipe 3. The limiting guide rail 8 is located at the outlet end of the second exhaust pipe 5, and a first channel 901 is formed between the end of the limiting guide rail 8 away from the outlet end of the second exhaust pipe 5 and the inner wall of the condensation chamber 403. The first inclined surface 405 can guide the flow of condensed water to the outlet end of the first exhaust pipe 3, thereby reducing the residual condensed water in the condensation chamber 403.

[0045] Furthermore, a water collecting tank 406 is provided on the first inclined surface 405, and the water collecting tank 406 is located at the outlet end of the first exhaust pipe 3. The condensed water on the first inclined surface 405 first flows to the water collecting tank 406, and then flows into the outlet end of the first exhaust pipe 3 through the water collecting tank 406. The water collecting tank 406 can collect the condensed water in the condensation chamber 403 to the water collecting tank 406 and then flow into the first exhaust pipe 3 together, further reducing the residual condensed water in the condensation chamber 403.

[0046] Furthermore, the first inclined surface 405 is provided with a second barrier rib 10 and a third barrier rib 11, and the limiting guide rail 8 is located between the second barrier rib 10 and the third barrier rib 11. The second barrier rib 10 and the third barrier rib 11 respectively form a second channel 1001 and a third channel 1101 with the inner wall of the condensation chamber 403, and the second channel 1001 and the third channel 1101 are both located on the side opposite to the first channel 901. Part of the steam flowing out of the first exhaust pipe 3 hits the surface of the third barrier rib 11 and condenses into water, and the other part flows through the first channel 901 through the third channel 1101. Part of the steam flowing through the first channel 901 hits the surface of the second barrier rib 10 and condenses into water, and the other part flows to the first barrier rib 9 through the second channel 1001. The condensed water on the first inclined surface 405 passes through the second channel 1001, the first channel 901 and the third channel 1101 in sequence, and finally flows to the water collecting tank 406. The second barrier rib 10 and the third barrier rib 11 can further improve the condensation efficiency of the steam.

[0047] The other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 1.

[0048] Example 3

[0049] This embodiment is a third embodiment of a dual-channel exhaust steam oven. This embodiment is similar to the embodiment, except that: Figure 6 As shown, the heating component further includes a second heating tube 12, and both ends of the second heating tube 12 are rotatably connected to opposite sides of the cooking cavity 101; a water storage tank 104 is provided at the bottom of the cooking cavity 101, and a part of the second heating tube 12 is located in the water storage tank 104. Condensed water in the cooking cavity 101 can be collected in the water storage tank 104 for heating by the second heating tube 12. The second heating tube 12 can not only heat the condensed water to generate steam, but also be used to assist in heating food in the cooking cavity 101. Since the second heating tube 12 is rotatable, the second heating tube 12 can be rotated to facilitate cleaning of the water storage tank 104.

[0050] Furthermore, the shape of the portion of the second heating tube 12 located in the water storage tank 104 is adapted to the shape of the water storage tank 104, so that the contact area between the second heating tube 12 and the condensed water in the water storage tank 104 can be increased, thereby improving the evaporation efficiency of the condensed water.

[0051] Furthermore, a second inclined surface 1011 is provided at the bottom of the cooking cavity 101, and the water collection tank 104 is located on the second inclined surface 1011. The height of the water collection tank 104 is lower than the height of the edge of the second inclined surface 1011. The second inclined surface 1011 can guide the condensed water to flow into the water collection tank 104, thereby increasing the amount of condensed water in the water collection tank 104 and reducing the condensed water remaining outside the water collection tank 104.

[0052] Furthermore, a thermostat (not shown) is included, which is electrically connected to the second heating tube 12. The thermostat can control the heating temperature of the second heating tube 12, so that the second heating tube 12 is heated to a set temperature to assist in cooking food in the cooking cavity 101 when necessary.

[0053] The other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 2.
