Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0024] The embodiments are described below with reference to the accompanying drawings, which do not limit the scope of the claims.
[0025] Please refer to Figure 1-3 As shown, this application embodiment provides a steam oven. When the steam oven is in operation, the inner cavity 1 of the steam oven is filled with a large amount of heating steam for heating the food to be steamed or baked. The steam oven includes the inner cavity 1 of the steam oven and a steam collection device 2. The steam collection device 2 includes a steam collection hood 21 and a return box 22. The steam collection hood 21 and the return box 22 are connected by a guide 23. The steam collection hood 21 is installed in the inner cavity 1 of the steam oven. After the heating steam comes into contact with the condensation surface of the steam collection hood 21, it can condense into liquid and then flow into the return box 22 along the outer wall of the steam collection hood 21 through the guide 23.
[0026] Specifically, the steam collection hood 21 is set at the top of the inner liner 1 of the steam oven, and the return box 22 is set at the bottom of the inner liner 1 of the steam oven. After the heated steam comes into contact with the condensation surface of the steam collection hood 21, it can condense into liquid and then flow down along the inner wall of the steam collection hood 21 under the action of gravity, and finally flow into the return box 22 through the guide 23, thereby realizing the collection of heated steam.
[0027] Specifically, the steam oven also includes a housing 10, and the inner liner 1 of the steam oven is fixedly disposed inside the housing 10.
[0028] In this embodiment of the application, by setting a water vapor collection device 2 in the inner cavity 1 of the steam oven, the heating steam is collected into the return box 22 through the steam collection cover 21, which avoids the phenomenon of water scale forming in the inner cavity 1 of the steam oven and improves the cleanliness of the inner wall of the inner cavity 1 of the steam oven.
[0029] In some embodiments, the water vapor collection device 2 further includes a filter device 24; the filter device 24 is disposed in the return box 22.
[0030] Specifically, the filtration device 24 can be a filter screen, through which the liquid after water vapor condensation can be filtered and stored in the return box 22.
[0031] Specifically, the filter device 24 is located at the connection between the flow guide 23 and the return box 22, and is used to filter the liquid entering the return box 22.
[0032] In this embodiment of the application, by providing a filter device 24 in the return box 22, the water vapor entering the return box 22 can be filtered out, and impurities in the water vapor can be filtered out, thereby ensuring the cleanliness of the liquid in the return box 22.
[0033] In some embodiments, the steam collection hood 21 has an arc-shaped structure, with the convex surface of the arc-shaped structure facing the top of the inner liner 1 of the steam oven.
[0034] Specifically, the steam collection hood 21 is a semi-circular hood made of metal. The condensation surface of the semi-circular hood faces the bottom of the inner liner 1 of the steam oven. After the heated steam comes into contact with the condensation surface, it will form water droplets, which will then flow into the guide 23 along the semi-circular hood and then collect in the return box 22.
[0035] Specifically, a flow guiding structure can be provided on the condenser surface, so that the water droplets condensed on the condenser surface can flow smoothly into the return box 22 along the flow guiding structure.
[0036] Specifically, the flow guiding structure can be guide protrusions evenly spaced on the condensation surface, allowing the liquid to flow smoothly into the return box 22 along the guide protrusions.
[0037] In this embodiment, by setting the steam collection hood 21 as an arc-shaped structure, water droplets can flow into the return box 22 along the surface of the arc-shaped steam collection hood 21 under the action of gravity, thus avoiding the phenomenon that water droplets fall directly onto the bottom of the inner liner 1 of the steam oven under the action of gravity.
[0038] In some embodiments, the flow guide 23 has a flow guide cavity 233 for liquid flow, the flow guide cavity 233 is connected to the return box 22, and the two ends of the arc-shaped structure are respectively arranged on the extension line of the flow guide cavity 233.
[0039] The two ends of the flow guiding structure extend toward the corresponding flow guiding component 23.
[0040] Specifically, the steam collection device 2 includes two return boxes 22 and two guide members 23; the two return boxes 22 are respectively arranged on both sides of the steam collection hood 21, and the guide cavity 233 of the guide member 23 is connected to the return box 22.
[0041] In this embodiment, the flow guide 23 has a flow guide cavity 233 for liquid flow. The flow guide cavity 233 is connected to the return box 22. The two ends of the arc-shaped structure are respectively set on the extension line of the flow guide cavity 233, which can ensure that water vapor can smoothly pass through the flow guide cavity 233 and enter the return box 22, thereby improving the collection efficiency of water vapor.
[0042] In some embodiments, the flow guide 23 includes a first flow guide 231 and a second flow guide 232, and a flow guide cavity 233 is formed between the first flow guide 231 and the second flow guide 232; the first flow guide 231 is provided with a first guide structure 2311 at one end facing the arc-shaped structure; the second flow guide 232 is provided with a second guide structure 2321 at one end facing the arc-shaped structure; the first guide structure 2311 and the second guide structure 2321 are disposed away from the flow guide cavity 233.
[0043] Specifically, the distance between the first guide member 231 and the second guide member 232 is greater than or equal to the thickness of the steam collection hood 21, thereby ensuring that all condensed water droplets on the steam collection hood 21 flow smoothly into the guide cavity 233.
[0044] Specifically, such as Figure 3 As shown, the first guide structure 2311 and the second guide structure can be arc-shaped flange structures, and the direction of the arc-shaped flange structures is opposite to the steam collection hood 21. This prevents water droplets from flowing to the outside of the guide cavity 233 after contacting the first guide member 231 and the second guide member 232 during the process of water droplets flowing into the guide cavity 233 along the outer wall of the steam collection hood 21, thereby improving the collection efficiency of water droplets.
[0045] In some embodiments, transition structures 211 are provided at both ends of the arc-shaped structure, and the transition structures 211 can be accommodated within the extension line of the guide cavity 233.
[0046] Specifically, the transition structure 211 can be a transition fillet, and the transition fillet is set above the transition structure 211, so that the water droplets flowing down the outer wall of the steam collection hood 21 gather at the transition fillet and then flow into the guide cavity 233, thereby further improving the collection efficiency.
[0047] In some embodiments, the reflux chamber 22 is located outside the inner cavity 1 of the steam oven.
[0048] Specifically, the inner cavity 1 of the steam oven is provided with a connecting hole, the diameter of which matches the diameter of the guide 23; the guide 23 can communicate with the connecting hole through the connecting hole.
[0049] Specifically, a sealing element is provided at the junction of the connecting hole and the guide 23 to prevent the heating steam inside the steam oven liner 1 from flowing out and affecting the heating effect.
[0050] In some embodiments, the steam oven also includes a water tank and a steam generator. One end of the water tank is connected to the steam generator via an external pipe. The water tank is used to supply liquid to the steam generator. The other end of the water tank is connected to the return tank 22 via an external pipe.
[0051] In this embodiment of the application, by connecting the return box 22, the water tank and the steam generator, the liquid is recycled, water resources are not wasted, and costs are saved.
[0052] In some embodiments, the inner cavity 1 of the steam oven is also provided with a support rack on which the food to be steamed or baked is placed.
[0053] Specifically, the inner cavity of the steam oven is equipped with multiple racks at equal intervals, which facilitates the simultaneous steaming and baking of multiple foods, thereby improving steaming and baking efficiency and saving steaming and baking time.
[0054] Example
[0055] Please refer to Figure 1-3 As shown, this application embodiment provides a steam oven. When the steam oven is in operation, the inner cavity 1 of the steam oven is filled with a large amount of heating steam for heating the food to be steamed or baked. The steam oven includes an inner cavity 1 and a steam collection device 2. The steam collection device 2 includes a steam collection hood 21 and a return box 22. The steam collection hood 21 and the return box 22 are connected by a guide 23. The steam collection hood 21 is installed in the inner cavity 1 of the steam oven. After the heating steam comes into contact with the condensation surface of the steam collection hood 21, it can condense into liquid and then flow into the return box 22 along the inner wall of the steam collection hood 21 through the guide 23.
[0056] The steam collection device 2 includes two return boxes 22 and two guide members 23. The steam collection hood 21 is an arc-shaped metal plate, which is fixedly installed in the inner liner 1 of the steam oven. The two return boxes 22 are respectively installed outside the inner liner 1 of the steam oven. One end of the guide member 23 is connected to the return box 22, and the other end of the guide member 23 is correspondingly installed with one end of the arc-shaped metal plate, so that one end of the arc-shaped metal plate is located within the extension line of the guide cavity 233 of the guide member 23.
[0057] A filter screen is provided on the side of the reflux box 22 facing the guide component 23, and the bottom of the reflux box 22 is connected to the water tank of the steam oven through the connecting external pipe. The water tank is used to provide sufficient liquid to the steam generator, so that the steam generator can generate enough heating steam in the inner cavity 1 of the steam oven to steam and bake the food to be steamed and baked on the support rack in the inner cavity 1 of the steam oven.
[0058] This application also provides the working process of a steam oven, as detailed below:
[0059] The food to be steamed or baked is placed on the rack in the steam oven. When the steam oven is working, the water tank provides sufficient liquid to the steam generator, which produces a large amount of heated steam. As the heated steam moves upward, an arc-shaped metal plate is provided at the top of the steam oven. The arc-shaped metal plate causes the heated steam to gather at the condensation surface. Utilizing the temperature difference of the arc-shaped metal plate, the heated steam adhering to the condensation surface condenses into water droplets. The water droplets move downward along the outer wall of the arc-shaped metal plate to both ends of the arc-shaped metal plate. Then, the water droplets fall into the guide cavity 233 of the guide component 23 and gather into a water flow. Driven by the subsequent water flow, the water flow moves along the guide cavity 233 to the return box 22. Because there is a filter screen in the return box 22, impurities in the water flow are removed by the filter screen. The filtered water flow then flows back to the water tank through the return box 22, thus completing the water circulation process.
