Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food cooking, and more particularly to a double-channel steam exhaust type steaming oven. BACKGROUND

[0002] The steam air-frying oven is a cooking appliance with pure steaming, baking and tender baking (i.e. steaming-baking mixed) functions. For example, a steam oven disclosed in the prior art comprises a shell, an inner container, a condensing assembly and a heating component. The inner container is located in the shell, and a steam outlet is formed in the inner container. The condensing assembly is located in the shell, and the condensing assembly has a condensing cavity in communication with the steam outlet. The condensing cavity is in communication with the outside through an air outlet hole provided at the top of the condensing assembly. The heating component is located in the shell and is arranged on the condensing assembly.

[0003] Due to cooking requirements, the pure steaming function requires a small steam outlet, otherwise a large amount of steam will be discharged, resulting in a large amount of condensate water being discharged, and the efficiency of pure steaming or steaming-baking will be reduced. The baking function requires a large steam outlet, so that the smoke, steam and odors generated during the baking process can be discharged in time, otherwise the cooking effect will be affected. For the tender baking function, the steam outlet of the oven also needs to be small, otherwise the cooking effect will be affected, because the moisture needs to be locked during the steaming-baking process. However, if the steam outlet is too small, the inner cavity of the oven is prone to have excessive pressure, which causes the problems of difficult door closing and abnormal sound during the cooking process. Since the above-mentioned prior art only provides one steam outlet, and the opening degree of the steam outlet cannot be adjusted, the pure steaming, baking and tender baking functions cannot achieve a relatively good cooking effect. SUMMARY

[0004] In view of the problem that the prior art only provides one steam outlet and the opening degree of the steam outlet cannot be adjusted, so that the pure steaming, baking and tender baking functions cannot achieve a relatively good cooking effect, the present application provides a double-channel steam exhaust type steaming oven, which can ensure that the pure steaming, baking and tender baking functions achieve a relatively good cooking effect.

[0005] To solve the above technical problems, the technical scheme provided by the present application is as follows:

[0006] A double-channel steam exhaust type steaming oven comprises a box body, a heating component, a first steam exhaust pipe and a steam exhaust seat. A cooking cavity and a first steam exhaust port are arranged in the box body. The heating component is arranged in the cooking cavity. The steam exhaust seat is connected with the box body. The first steam exhaust port is in communication with the steam exhaust seat through the first steam exhaust pipe. The box body is further provided with a second steam exhaust port, and the second steam exhaust port is in communication with the steam exhaust seat through a second steam exhaust pipe. An opening degree adjusting mechanism is arranged at the outlet end of the first steam exhaust pipe or the second steam exhaust pipe, and the opening degree adjusting mechanism is located in the steam exhaust seat.

[0007] In the above technical solution, the outlet of one of the first steam exhaust pipe and the second steam exhaust pipe is always open, and the outlet of the other one can be adjusted by the opening degree adjusting mechanism. The steam in the cooking cavity can enter the steam exhaust seat through the first steam exhaust pipe and / or the second steam exhaust pipe, and then be exhausted to the outside environment. When the pure steaming function is used, the steam exhaust pipe with the always open outlet can exhaust the excess steam generated during steaming, and the outlet of the other steam exhaust pipe is closed, which can avoid excessive steam exhaust and ensure the steaming efficiency. When the steam pressure is too large, the opening degree adjusting mechanism can adjust the opening degree of the outlet of the other steam exhaust pipe, so as to keep the pressure of the cooking cavity stable and avoid difficult opening or abnormal sound when opening the door. When the baking function is used, although steam is not needed, the steam exhaust pipe with the always open outlet can ensure the air flow in the cooking cavity. When the pressure in the cooking cavity is too large, the opening degree adjusting mechanism can adjust the opening degree of the outlet of the other steam exhaust pipe, so as to avoid the smoke and odor staying in the cooking cavity. When the tender baking function is used, the steam exhaust pipe with the always open outlet can exhaust the excess steam, smoke and odor generated during cooking, so as to avoid the food surface being too wet and the smoke and odor staying in the cooking cavity. When the pressure in the cooking cavity is too large, the opening degree adjusting mechanism can adjust the opening degree of the outlet of the other steam exhaust pipe to adjust the exhaust amount of steam, smoke and odor, so as to ensure that the outside of the food can achieve the ideal baking effect.

[0008] Preferably, the opening degree adjusting mechanism can be a sliding piece slidingly arranged at the outlet end of the first steam exhaust pipe or the second steam exhaust pipe. The sliding piece can slide along the axis direction of the outlet of the first steam exhaust pipe or the second steam exhaust pipe, or can slide along the vertical direction of the aforementioned direction. The sliding of the sliding piece can be provided with multiple gears, and each gear corresponds to a different opening degree. The opening degree can be adjusted by manually sliding the sliding piece to the corresponding gear according to the actual needs.

[0009] Preferably, the opening degree adjusting mechanism includes a micro-pressure ball and an elastic piece. The outlet end of the first steam exhaust pipe or the second steam exhaust pipe is provided with a limiting guide rail, the micro-pressure ball is slidingly arranged in the limiting guide rail, and one end of the elastic piece is connected with the micro-pressure ball and the other end is abutted with the inner wall of the steam exhaust seat. Assuming that the opening degree adjusting mechanism is arranged at the outlet end of the second steam exhaust pipe, when the pressure in the cooking cavity is large enough, the micro-pressure ball can be pushed open and compress the elastic piece, so that the outlet of the second steam exhaust pipe is exposed to a certain size, and the steam in the cooking cavity can enter the steam exhaust seat through the second steam 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 steam exhaust pipe also gradually increases. Compared with other shapes, the micro-pressure ball structure is simpler, and can block the first steam exhaust pipe or the second steam exhaust pipe more tightly. In addition, during the steam exhaust process, the steam or gas passing through the surface of the micro-pressure ball has smaller resistance, so there is no problem of poor exhaust and large exhaust noise.

[0010] Preferably, the steam exhaust seat is provided with a condensing cavity and an exhaust hole, and the heating component is at least partially located at the bottom of the cooking cavity. The steam exhausted from the first steam exhaust pipe and the second steam exhaust pipe enters the condensing cavity, and part of the steam is condensed into water by contacting the inner wall of the condensing cavity, and the other part of the steam is exhausted from the steam exhaust seat through the exhaust hole. The condensed water in the condensing cavity can flow back to the cooking cavity through the first steam exhaust pipe or the second steam exhaust pipe with the outlet always open, so as to heat the heating component, thereby generating more steam. Thus, the condensation and recycling of the steam are achieved, and the exhaust amount of the steam is reduced.

[0011] Preferably, a plurality of first blocking ribs are arranged in the condensing cavity, and the first blocking ribs are located between the outlet ends of the first steam exhaust pipe and the second steam exhaust pipe and the exhaust hole. The first steam exhaust port and the second steam exhaust port are respectively communicated with the condensing cavity through the first steam exhaust pipe and the second steam exhaust pipe. After the steam enters the condensing cavity, the steam flows in the direction of the exhaust hole, and thus the steam also flows through the first blocking ribs and is condensed into water on the surface of the first blocking ribs. At the same time, the condensed water carried by the flowing steam is also blocked by the first blocking ribs. The plurality of first blocking ribs can improve the condensation efficiency of the steam and the recycling rate of the steam, and further reduce the exhaust amount of the steam.

[0012] Preferably, the first blocking ribs are arranged in multiple rows, and adjacent two rows of the first blocking ribs are staggered. Such an arrangement can reduce the turbulence and stagnation of the steam flow, help the steam flow on the surface of the first blocking ribs, reduce the dead zone of the steam flow, enable the steam to be more uniformly and completely condensed, and block more condensed water.

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

[0014] Preferably, a water collecting groove is arranged on the first inclined surface, and the water collecting groove is located at the outlet end of the first steam exhaust pipe. The condensed water on the first inclined surface first flows to the water collecting groove, and then flows into the outlet end of the first steam exhaust pipe through the water collecting groove. The water collecting groove can collect the condensed water in the condensing cavity and then flow into the first steam exhaust pipe together, thereby further reducing the residual condensed water in the condensing cavity.

[0015] Preferably, the first inclined surface is further provided with a second blocking rib and a third blocking rib, the limiting guide rail is located between the second blocking rib and the third blocking rib, the second blocking rib and the third blocking rib form a second channel and a third channel with the inner wall of the condensing cavity respectively, and the second channel and the third channel are located on the opposite side of the first channel. The steam flowing out of the first steam pipe condenses into water on the surface of the third blocking rib, another part of the steam flows through the third channel and the first channel, the steam flowing through the first channel condenses into water on the surface of the second blocking rib, and another part of the steam flows through the second channel to the first blocking rib. The condensed water on the first inclined surface sequentially passes through the second channel, the first channel and the third channel, and finally flows to the water collecting groove. The second blocking rib and the third blocking rib can further improve the condensation efficiency of the steam.

[0016] Preferably, the elastic member adopts a spring structure. Compared with an elastic material member, the spring structure still maintains the same elastic performance after being deformed and restored for many times, and is more reliable to use.

[0017] Preferably, the heating component comprises a second heating pipe, two ends of the second heating pipe are rotationally connected to opposite sides of the cooking cavity, the bottom of the cooking cavity is provided with a water collecting groove, and at least part of the second heating pipe is located in the water collecting groove. The condensed water in the cooking cavity can be collected in the water collecting groove for heating by the second heating pipe. The second heating pipe can not only heat the condensed water to generate steam, but also can be used to assist heating of food in the cooking cavity. Since the second heating pipe is rotatable, the second heating pipe can be rotated to facilitate cleaning of the water collecting groove.

[0018] The present application has the following beneficial effects:

[0019] 1. The double-channel steam exhaust structure is adopted, the outlet of one steam exhaust pipe is always open, and the opening degree of the outlet of the other steam exhaust pipe can be adjusted by the opening degree adjusting mechanism. The problems of poor exhaust, difficult door closing or abnormal sound of door closing can be avoided, and the functions of pure steaming, baking and tender baking in the cooking cavity can achieve relatively better cooking effects.

[0020] 2. The steam in the cooking cavity enters the condensing cavity in the steam exhaust seat and can be condensed into water. The condensed water can be returned to the cooking cavity through the first steam exhaust pipe to be heated to form steam, so as to form the circulation of steam condensation and evaporation, and the exhaust amount of steam can be reduced.

[0030] The technical solutions of the present application will be further described in detail below through specific embodiments, and in conjunction with the drawings:

[0031] Embodiment 1

[0032] This embodiment is a first embodiment of a double-channel steam exhaust type steaming oven, which is combined with Figures 1 to 4As shown, it comprises a box body 1, a heating component, a steam generator (not shown in the figure), a first steam discharge pipe 3 and a steam discharge seat 4; the box body 1 is internally provided with a cooking cavity 101 and a first steam discharge port 102; the heating component comprises a first heating pipe 2 arranged at the top of the cooking cavity 101; the steam generator is connected with the box body 1 and the outlet end of the steam generator is communicated with the cooking cavity 101; the steam discharge seat 4 is connected with the box body 1; the first steam discharge port 102 is communicated with the steam discharge seat 4 through the first steam discharge pipe 3; it further comprises a second steam discharge pipe 5, the box body 1 is internally provided with a second steam discharge port 103, the second steam discharge port 103 is communicated with the steam discharge seat 4 through the second steam discharge pipe 5, and the outlet end of the second steam discharge pipe 5 is provided with an opening degree adjusting mechanism, which is located in the steam discharge seat 4.

[0033] The opening degree adjusting mechanism can be a sliding member slidingly arranged at the outlet end of the second steam discharge pipe 5, which can slide along the axis direction of the outlet of the second steam discharge pipe 5 or the vertical direction of the aforementioned direction. The sliding of the sliding member can be provided with multiple gears, and each gear corresponds to a different opening degree. The sliding member can be manually slid to the corresponding gear to adjust the opening degree according to the actual needs.

[0034] In this embodiment, the opening degree adjusting mechanism comprises a micro-pressure ball 6 and an elastic member 7, the outlet end of the second steam discharge pipe 5 is provided with a limiting guide rail 8, the micro-pressure ball 6 is slidingly arranged in the limiting guide rail 8, one end of the elastic member 7 is connected with the micro-pressure ball 6, and the other end is abutted with the inner wall of the steam discharge seat 4. Assuming that the opening degree adjusting mechanism is arranged at the outlet end of the second steam discharge pipe 5, when the pressure in the cooking cavity 101 is large enough, the micro-pressure ball 6 can be pushed open and compress the elastic member 7, so that the outlet of the second steam discharge pipe 5 is exposed to a certain size, and the steam in the cooking cavity 101 can enter the steam discharge seat 4 through the second steam discharge pipe 5. Compared with other structures, the micro-pressure ball 6 has a simpler structure and can block the outlet of the second steam discharge pipe 5 more tightly. In addition, during the steam discharge process, the steam or gas passing through the surface of the micro-pressure ball 6 has smaller resistance, so the problems of poor exhaust and loud exhaust noise do not occur.

[0035] Specifically, the elastic member 7 adopts a spring structure. Compared with the elastic material member, the spring structure still maintains the same elastic performance after being deformed and restored for many times, and is more reliable to use.

[0036] The working principle or working process of the embodiment is as follows: the outlet of the first steam exhaust pipe 3 is always open, the outlet of the second steam exhaust pipe 5 can be adjusted in size by the opening degree adjusting mechanism, and 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 exhausted to the outside 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 pipe 2 does not work, and the first steam exhaust pipe 3 with the always-open outlet can exhaust the excess steam generated in the steaming process. Since the outlet of the second steam exhaust pipe 5 is closed by the micro-pressure ball 6, too much steam can be avoided from being exhausted and the steaming efficiency can be ensured. When the steam pressure is too large, the micro-pressure ball 6 can be pushed open and compress the elastic member 7, so that the outlet of the second steam exhaust pipe 5 is exposed to a certain size. The steam in the cooking cavity 101 can then 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 that the micro-pressure ball 6 moves gradually increases, and the opening degree of the outlet of the second steam exhaust pipe 5 also gradually increases, so as to keep the pressure in the cooking cavity 101 stable and avoid the difficulty in closing the door or the abnormal sound when the door is closed. When the baking function is used, the heat source in the cooking cavity 101 is only the heat radiation of the first heating pipe 2. Although the baking function does not need steam, the first steam exhaust pipe 3 with the always-open outlet can ensure the air flow in the cooking cavity 101. When the pressure in the cooking cavity 101 is too large, the micro-pressure ball 6 can move to adjust the opening degree of the outlet of the second steam exhaust pipe 5, so as to avoid the 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 pipe 2. The first steam exhaust pipe 3 with the always-open outlet can exhaust the excess steam, smoke and odor generated in the cooking process, so as to avoid the food surface from being too wet and avoid the smoke and odor from staying in the cooking cavity 101. When the pressure in the cooking cavity 101 is too large, the micro-pressure ball 6 can move to adjust the opening degree of the second steam exhaust pipe 5, so as to adjust the exhaust amount of the steam, smoke and odor and ensure that the outside of the food can achieve the ideal baking effect.

[0037] The beneficial effects of the embodiment are as follows:

[0038] 1. The double-channel steam exhaust structure is adopted, the outlet of one steam exhaust pipe is always open, and the opening degree of the outlet of the other steam exhaust pipe can be adjusted by the opening degree adjusting mechanism. The pure steaming, baking and tender-baking functions in the cooking cavity can all achieve relatively good cooking effects, and the problems of difficulty in closing the door and abnormal sound when the door is closed due to poor exhaust can be avoided.

[0039] 2. The steam in the cooking cavity can be condensed into water in the condensing cavity of the steam exhaust seat, the condensed water can be returned to the cooking cavity through the first steam exhaust pipe to be heated to form steam, so as to form the circulation of steam condensation and evaporation, and the exhaust amount of steam can be reduced.

[0040] Embodiment 2

[0041] The second embodiment of the double-channel steam exhaust type steaming oven is similar to the first embodiment, except that Figures 1 to 5 As shown in FIG. 4, the steam exhaust seat 4 includes a seat body 401 and a top cover 402 detachably connected to the seat body 401, and a condensation cavity 403 is formed between the seat body 401 and the top cover 402. The top cover 402 is provided with an exhaust hole 404. The heating component is partially located at the bottom of the cooking cavity 101. The steam discharged from the first steam exhaust pipe 3 and the second steam exhaust pipe 5 enters the condensation cavity 403, part of which contacts the inner wall of the condensation cavity 403 and condenses into water, and the other part is discharged from the steam exhaust seat 4 through the exhaust hole 404. The condensed water in the condensation cavity 403 can flow back to the cooking cavity 101 through the first steam exhaust pipe 3 with the outlet always open to heat the heating component, thereby generating more steam, so as to realize the condensation and recycling of steam and reduce the exhaust amount of steam.

[0042] Further, a plurality of first blocking ribs 9 are arranged in the condensation cavity 403, and the first blocking ribs 9 are located between the outlet ends of the first steam exhaust pipe 3 and the second steam exhaust pipe 5 and the exhaust hole 404. The first steam exhaust port 102 and the second steam exhaust port 103 are respectively communicated with the condensation cavity 403 through the first steam exhaust pipe 3 and the second steam exhaust pipe 5. The steam entering the condensation cavity 403 will flow in the direction of the exhaust hole 404, so the steam will also pass through the first blocking ribs 9 and condense into water on the surface of the first blocking ribs 9. At the same time, the condensed water carried in the flowing steam will also be blocked by the first blocking ribs 9. The arrangement of a plurality of first blocking ribs 9 can improve the condensation efficiency of the steam and the recycling rate of the steam, and further reduce the exhaust amount of the steam.

[0043] Further, the first blocking ribs 9 are distributed in multiple rows, and the adjacent two rows of first blocking ribs 9 are staggered. Such arrangement can reduce the turbulence and stagnation of the steam flow, help the steam flow on the surface of the first blocking ribs 9, reduce the dead zone of the steam flow, make the steam more uniformly and completely condensed, and block more condensed water.

[0044] Further, a first inclined surface 405 is arranged in the condensation cavity 403, and the first blocking ribs 9 and the limiting guide rails 8 are located on the first inclined surface 405. The first blocking ribs 9, the outlet end of the second steam exhaust pipe 5, and the outlet end of the first steam exhaust pipe 3 are sequentially arranged along the extension direction of the first inclined surface 405, and the position of the first blocking ribs 9 on the first inclined surface 405 is higher than the position of the outlet end of the first steam exhaust pipe 3. The limiting guide rail 8 is located at the outlet end of the second steam 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 steam exhaust pipe 5 and the inner wall of the condensation cavity 403. The first inclined surface 405 can guide the flow of condensed water to the outlet end of the first steam exhaust pipe 3, reducing the residue of condensed water in the condensation cavity 403.

[0045] Further, the first inclined surface 405 is provided with a water collecting groove 406, which is located at the outlet end of the first steam discharge pipe 3. The condensed water on the first inclined surface 405 first flows into the water collecting groove 406 and then flows into the outlet end of the first steam discharge pipe 3 through the water collecting groove 406. The water collecting groove 406 can collect the condensed water in the condensing cavity 403 and then flow into the first steam discharge pipe 3 together, further reducing the residual condensed water in the condensing cavity 403.

[0046] Further, the first inclined surface 405 is further provided with a second blocking rib 10 and a third blocking rib 11, and the limiting guide rail 8 is located between the second blocking rib 10 and the third blocking rib 11. The second blocking rib 10 and the third blocking rib 11 form a second channel 1001 and a third channel 1101 between the inner wall of the condensing cavity 403, respectively. The second channel 1001 and the third channel 1101 are located on the side opposite to the first channel 901. The steam flowing out of the first steam discharge pipe 3 condenses into water on the surface of the third blocking rib 11, and another part flows through the third channel 1101 and the first channel 901. The steam flowing through the first channel 901 condenses into water on the surface of the second blocking rib 10, and another part flows through the second channel 1001 to the first blocking rib 9. The condensed water on the first inclined surface 405 flows through the second channel 1001, the first channel 901 and the third channel 1101 in turn, and finally flows into the water collecting groove 406. The second blocking rib 10 and the third blocking rib 11 can further improve the condensation efficiency of the steam.

[0047] The other features, working principles and beneficial effects of the present embodiment are the same as those of Embodiment 1.

[0048] Embodiment 3

[0049] The present embodiment is a third embodiment of a double-channel steam discharge type steaming oven. The present embodiment is similar to Embodiment 2, except that, as shown in Figure 6 the heating component further includes a second heating pipe 12, both ends of the second heating pipe 12 being rotatably connected to opposite sides of the cooking cavity 101. The bottom of the cooking cavity 101 is provided with a water collecting groove 104, and a portion of the second heating pipe 12 is located in the water collecting groove 104. The condensed water in the cooking cavity 101 can be collected in the water collecting groove 104 for heating by the second heating pipe 12. The second heating pipe 12 can not only heat the condensed water to generate steam, but also be used to assist in heating the food in the cooking cavity 101. Since the second heating pipe 12 is rotatable, the second heating pipe 12 can be rotated to facilitate cleaning of the water collecting groove 104.

[0050] Further, the portion of the second heating pipe 12 located in the water collecting groove 104 is shaped to match the shape of the water collecting groove 104, which can increase the contact area between the second heating pipe 12 and the condensed water in the water collecting groove 104, thereby improving the evaporation efficiency of the condensed water.

[0051] Further, the bottom of the cooking cavity 101 is provided with a second slope 1011, and the water collecting groove 104 is located on the second slope 1011, and the height of the location of the water collecting groove 104 is lower than the height of the edge of the second slope 1011. The second slope 1011 can guide the condensed water to flow into the water collecting groove 104, thereby increasing the amount of condensed water in the water collecting groove 104 and reducing the residue of the condensed water outside the water collecting groove 104.

[0052] Further, a temperature controller (not shown in the figure) is further included, and the temperature controller is electrically connected with the second heating pipe 12. The temperature controller can control the heating temperature of the second heating pipe 12, so as to heat the second heating pipe 12 to a set temperature when needed to assist the cooking of the food in the cooking cavity 101.
