The steam in the inner container can enter the condensation structure, condense into water in the condensation structure, and then flow into the inner container.

[0004] However, the condensed water is prone to dripping onto the food. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a steaming oven, and the condensed water is not prone to dripping onto the food.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] The present application provides a steaming oven, which comprises:

[0008] An inner container, the inner container is provided with a cooking cavity;

[0009] A steam structure, the steam structure is in communication with the inner container, and the steam structure is configured to deliver steam into the inner container;

[0010] An air duct structure, the air duct structure is arranged on one side of the inner container, and the air duct structure is in communication with the outside of the steaming oven;

[0011] A connecting structure, the connecting structure is arranged at the lower part of the inner container, and the connecting structure is in communication with the inner container;

[0012] A condensation structure, the condensation structure is in communication with the connecting structure and the air duct structure; the steam in the cooking cavity flows into the air duct structure through the connecting structure and the condensation structure, and the condensed water formed in the condensation structure flows into the cooking cavity through the connecting structure.

[0013] The steaming oven provided by the present application comprises an inner container, a steam structure, an air duct structure, a connecting structure, and a condensation structure. The steam structure is used to deliver steam into the cooking cavity of the inner container. The connecting structure is used to communicate the condensation structure and the inner container. The steam of the inner container enters the air duct structure through the connecting structure and the condensation structure. Part of the steam condenses into water in the condensation structure and then flows into the inner container through the connecting structure. Part of the steam enters the air duct structure. The air duct structure is used to discharge the steam to the outside of the steaming oven. Since the connecting structure is arranged at the lower part of the inner container, the position of the condensed water entering the inner container is low, and the condensed water is not prone to dripping onto the food.

[0014] In some embodiments, the air duct structure is arranged above the inner container.

[0015] In this way, when the air duct structure is arranged above the inner container and the connecting structure is arranged at the lower part of the inner container, the distance between the air duct structure and the connecting structure is large, and the length of the condensing structure can be large, which is conducive to improving the condensing effect of the steam in the condensing structure, effectively solving the problem that the gas containing heat and water vapor is discharged from the steam oven, causing the surrounding environment to be overheated and humid.

[0016] In some embodiments, the connecting structure is arranged at one side of the inner container along the width direction.

[0017] The connecting structure is provided with an inner cavity, and the distance between the inner bottom wall of the inner cavity and the bottom wall of the inner container is less than 100 mm.

[0018] In this way, the steam structure is usually arranged at the back of the inner container, and the space on both sides of the inner container along the width direction is large, which is conducive to the arrangement of the connecting structure and the condensing structure. Moreover, the height of the connecting structure is low, and when the user places the food on the baking tray or grill, the height of the food is not easy to be lower than the height of the connecting structure, so that the connecting structure is far away from the food and is not easy to drip onto the food.

[0019] In some embodiments, a shelf is further included, the shelf is arranged in the cooking cavity, and the shelf is provided with a plurality of mounting portions which are arranged at intervals along the height direction.

[0020] The plurality of mounting portions include a first mounting portion, a second mounting portion, and a third mounting portion, the first mounting portion is close to the bottom wall of the inner container, the second mounting portion is above the first mounting portion, and the third mounting portion is above the second mounting portion.

[0021] The connecting structure is provided with an inner cavity, and the inner bottom wall of the inner cavity is not higher than the second mounting portion.

[0022] In this way, since the second mounting portion and the third mounting portion are the most commonly used positions when the user cooks, it is necessary to ensure that when the baking tray or grill is placed on the second mounting portion, the condensed water flowing back from the connecting structure is not easy to flow into the baking tray or grill under the impact of falling. Therefore, the height of the connecting structure should not be higher than the height of the baking tray or grill on the second mounting portion.

[0023] In some embodiments, the condensing structure includes:

[0024] A connecting pipe connected with the connecting structure;

[0025] A condensing pipe connected with the connecting pipe, the condensing pipe is provided with a plurality of openings arranged at intervals, the condensing pipe is located in the air duct structure, and the extension direction of the condensing pipe is parallel to the horizontal plane.

[0026] The fixing member is located in the air duct structure and connected with the air duct structure, and the condensing pipe is connected with the fixing member.

[0027] In this way, the steam in the inner container enters the condensing pipe through the connecting structure and the connecting pipe. The steam entering the condensing pipe is cooled, part of the steam is converted into condensed water and remains in the condensing pipe, and part of the cooled steam is discharged into the air duct structure through the opening of the condensing pipe and then blown to the outside of the steam oven.

[0028] In some embodiments, the plurality of openings includes a plurality of first openings and a second opening, and the plurality of first openings are arranged at intervals along the extension direction of the condensing pipe.

[0029] The second opening is arranged at one end of the condensing pipe away from the connecting pipe.

[0030] The fixing member is provided with a third opening, which is in communication with the air duct cavity of the air duct structure and is in communication with the second opening.

[0031] In this way, the steam can move from one end of the condensing pipe away from the fixing member to one end close to the fixing member and escape from the fixing member, and the flow path is long, which is beneficial to improve the condensation effect.

[0032] In some embodiments, the air duct structure includes:

[0033] The support plate is arranged above the inner container.

[0034] The cover plate is arranged above the support plate, and the air duct cavity is formed between the cover plate and the support plate, the air duct cavity is in communication with the outside of the steam oven, and the condensing pipe is located in the air duct cavity.

[0035] The fan is arranged on one side of the cover plate, and the air outlet of the fan is in communication with the air duct cavity.

[0036] In this way, the condensing pipe is located in the air duct cavity, and the cooling effect of the fan on the condensing pipe is good, and the steam passing through the opening of the condensing pipe can directly flow into the air duct cavity and be blown to the outside under the action of the fan.

[0037] In some embodiments, the inner diameter of the connecting structure is not less than 12 mm.

[0038] In this way, the flow speed of the steam is small, and the steam is not easy to hinder the flow of the condensed water.

[0039] In some embodiments, the sum of the opening areas of the third opening and the plurality of first openings is greater than the cross-sectional area of the inner cavity of the connecting structure.

[0040] In this way, the flow speed of the steam is small, and the steam is not easy to hinder the flow of the condensed water.

[0041] In some embodiments, the inner container is provided with a connecting port in communication with the cooking cavity, the connecting port being located at a lower portion of the inner container;

[0042] The connecting structure comprises:

[0043] The first connecting member is inserted into the connecting port, and part of the first connecting member is located outside the inner container through the connecting port. The first connecting member is provided with a mounting cavity on one side facing the inner wall of the inner container;

[0044] The sealing member is located in the mounting cavity and between the first connecting member and the inner wall of the inner container.

[0045] In this way, by providing the sealing member and mounting the sealing member in the mounting cavity, the sealing member is not easy to fall off, and the sealing effect is better. BRIEF DESCRIPTION OF DRAWINGS

[0074] To make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0075] In the related art, the steam oven discharges the excess steam in the inner container by the siphon effect of the air flow blown by the heat dissipation fan to maintain the steam pressure in the inner container through the principle of discharging the heat dissipation fan through the exhaust hole at the top of the inner container. However, the following problems are caused. 1. Since the upper part of the inner container is the air duct structure, the excess steam can enter the air duct structure through a short path and be blown out along with the air duct cavity, the movement distance of the steam in the air duct cavity is short, so the discharged hot steam lacks effective condensation, the steam directly discharged to the outside of the machine has a high temperature and high humidity, the discharged steam contains a large amount of water vapor, which is easy to condense and drop at the outlet of the air duct cavity and the panel of the steam oven, causing pollution of the cabinet and humidity of the kitchen. 2. Meanwhile, the exhaust hole at the top is generally communicated with the end of the air duct cavity of the air duct structure, the hot steam cannot be effectively dispersed, causing concentrated exhaust of hot air. 3. Since the condensed water is not recycled, water resources are wasted, and the endurance time is short. 4. Since the exhaust hole is located at the top of the inner container, condensed water is inevitably generated during the exhaust process and flows back to the inner container through the exhaust hole, the backflow of the condensed water will drop onto the baking tray directly below, which will pollute the food materials and cause poor cooking effect.

[0076] Based on this, in the related art, the steam oven includes an inner container, an air duct structure, and a condensing structure. The air duct structure is communicated with the inner container and the outside of the inner container. The condensing structure is communicated with the air duct structure and the inner container. Part of the steam in the inner container can enter the condensing structure, condense into water in the condensing structure, and flow into the inner container, and part of the steam in the inner container can flow to the outside of the steam oven through the condensing structure and the air duct structure. However, the condensed water enters the inner container from the top of the inner container, and the condensed water is easy to drop onto the food.

[0077] To overcome the defects in the related art, the steam oven provided in the present application comprises an inner container, a steam structure, an air duct structure, a connecting structure and a condensing structure, the steam structure is used for conveying steam into the cooking cavity of the inner container, the connecting structure is used for connecting the condensing structure and the inner container, the steam of the inner container enters the air duct structure through the connecting structure and the condensing structure, part of the steam is condensed into water in the condensing structure and then flows into the inner container through the connecting structure, and part of the steam enters the air duct structure, the air duct structure is used for discharging the steam to the outside of the steam oven, and since the connecting structure is arranged at the lower part of the inner container, the condensed water enters the inner container at a lower position and is not easy to drop onto the food.

[0078] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.

[0106] Referring to Figure 4 In some embodiments, the steam oven includes an air duct structure 500. The air duct structure 500 is used to discharge excess steam in the inner container 200 to the outside of the steam oven.

[0107] The air duct structure 500 communicates with the inner container 200, and the air duct structure 500 communicates with the outside of the steam oven. Excess steam in the inner container 200 enters the air duct structure 500, and then flows to the outside of the steam oven to maintain the steam pressure in the inner container 200.

[0108] The air duct structure 500 can communicate with the front side of the steam oven. The front side is the side of the shell 100 facing the door 300.

[0109] The air duct structure 500 is arranged on one side of the inner container 200. Specifically, the air duct structure 500 can be arranged above the inner container 200.

[0110] Figure 5 The structure of the inner container, shelf and connecting structure in the steam oven provided by the embodiments of the present application is shown in the structure diagram.

[0111] Referring to Figure 4 and Figure 5 In some embodiments, the steam oven includes a connecting structure 600. The connecting structure 600 is used to communicate the connecting structure 600 and the condensing structure 700.

[0112] The connecting structure 600 is arranged at the lower part of the inner container 200. That is, the connecting structure 600 can be arranged at the bottom of the inner container 200, or near the bottom. Alternatively, the distance from the connecting structure 600 to the top of the inner container 200 is greater than the distance from the connecting structure 600 to the bottom of the inner container 200.

[0113] In some embodiments, the steam oven includes a condensing structure 700.

[0114] The condensing structure 700 is in communication with the connecting structure 600 and the air duct structure 500.

[0115] It can be understood that the steam in the inner container 200 enters the air duct structure 500 through the connecting structure 600 and the condensing structure 700. Part of the steam is condensed into water in the condensing structure 700 and then flows into the inner container 200 through the connecting structure 600. Part of the steam enters the air duct structure 500, which is used to discharge the steam to the outside of the steam oven. Since the connecting structure 600 is arranged at the lower part of the inner container 200, the condensed water enters the inner container 200 at a lower position and is not easy to drip onto the food.

[0116] Moreover, when the air duct structure is arranged above the inner container 200 and the connecting structure 600 is arranged at the lower part of the inner container 200, the distance between the air duct structure and the connecting structure 600 is large, and the length of the condensing structure 700 can be large, which is beneficial to improve the condensing effect of the steam in the condensing structure 700 and effectively solve the problem that the gas containing heat and water vapor discharged from the steam oven causes the surrounding environment to be overheated and over-humidified.

[0118] Referring to FIG. 1, in some embodiments, the connecting structure 600 is arranged at one side of the inner container 200 along the width direction. It can be understood that the steam structure 400 is usually arranged at the back of the inner container 200, and the space at both sides of the inner container 200 along the width direction is large, which is beneficial to the arrangement of the connecting structure 600 and the condensing structure 700. Moreover, when the user cooks, the food is usually placed at the middle position along the width direction, so that the connecting structure 600 is far away from the food and is not easy to drip onto the food.

[0119] Figure 6 Referring to FIG. 3, in some embodiments, the distance d between the connecting structure 600 and the bottom wall of the inner container 200 is less than 100 mm. In this way, the height of the connecting structure 600 is low, and when the user places the food on the baking tray or baking rack, the height of the food is not easy to be lower than the height of the connecting structure 600, so that the condensed water is not easy to drip onto the food.

[0120] Figure 8

[0121] ​​​​​​It can be understood that the condensed water flows into the inner container 200 along the bottom wall of the inner cavity of the connecting structure 600 under the action of gravity, and therefore, the height of the bottom wall of the inner cavity of the connecting structure 600 needs to be limited. Specifically, the distance from the bottom wall of the inner cavity of the connecting structure 600 to the outer bottom wall of the inner container 200 is less than 100 mm.

[0122] In some embodiments, the distance d from the bottom wall of the inner cavity of the connecting structure 600 to the outer bottom wall of the inner container 200 is less than 95 mm.

[0123] In some embodiments, the distance d from the bottom wall of the inner cavity of the connecting structure 600 to the outer bottom wall of the inner container 200 is less than 90 mm.

[0124] In some embodiments, the distance d from the bottom wall of the inner cavity of the connecting structure 600 to the outer bottom wall of the inner container 200 is 88 mm, 86 mm, or 85 mm, 80 mm, 70 mm, 60 mm, 50 mm, 40 mm, 30 mm, or 20 mm.

[0125] Referring to Figures 5 to 8 As shown, the shelf 800 is further included in some embodiments. The shelf 800 is used to place a baking tray or grill.

[0126] The shelf 800 is arranged in the cooking cavity.

[0127] The shelf 800 is connected with the side wall of the cooking cavity.

[0128] Specifically, the number of the shelf 800 can be two, and the two shelves 800 are arranged on opposite sides of the inner container 200 in the width direction.

[0129] The width direction is the direction indicated by the X axis.

[0130] Referring to Figure 8 As shown, the shelf 800 is provided with a plurality of mounting portions 810, and the plurality of mounting portions 810 are arranged in the height direction.

[0131] The plurality of mounting portions 810 include a first mounting portion 811, a second mounting portion 812, and a third mounting portion 813. The first mounting portion 811 is close to the bottom wall of the inner container 200, the second mounting portion 812 is above the first mounting portion 811, and the third mounting portion 813 is above the second mounting portion 812.

[0132] It should be noted that since the second mounting portion 812 and the third mounting portion 813 are the most commonly used positions for users to cook, it is necessary to ensure that when the baking tray is placed on the second mounting portion 812, the condensed water flowing back from the connecting structure 600 is not easily flowed into the baking tray or grill under the impact of falling, and therefore, the height of the connecting structure 600 should not be higher than the height of the baking tray or grill on the second mounting portion 812.

[0133] In some embodiments, the connecting structure 600 is provided with an inner cavity, and the inner bottom wall of the inner cavity is not higher than the second mounting portion 812.

[0134] It can be understood that the condensed water flows to the inner container 200 along the bottom wall of the inner cavity of the connecting structure 600 under the action of gravity, and therefore, the height of the bottom wall of the inner cavity of the connecting structure 600 needs to be limited. Specifically, the bottom wall of the inner cavity of the connecting structure 600 is below the top surface of the second mounting portion 812, or the bottom wall of the inner cavity of the connecting structure 600 is flush with the top surface of the second mounting portion 812.

[0150] Figure 13 To Figure 4 Structure schematic diagram after removing the cover plate.

[0151] Referring to Figure 4 and Figure 13 In some embodiments, the air duct structure 500 comprises a support plate 510. The support plate 510 can play a supporting and bearing role, and is used to mount other devices of the air duct structure 500.

[0152] The support plate 510 is arranged above the inner container 200.

[0153] In some embodiments, the air duct structure 500 comprises a cover plate 520. The cover plate 520 is used to form an air duct cavity.

[0154] The cover plate 520 is arranged on the support plate 510, and the cover plate 520 and the support plate 510 form an air duct cavity therebetween. The air duct cavity is in communication with the outside of the steam oven.

[0155] In some embodiments, the air duct structure 500 comprises an air blower 530. The air blower 530 is used to blow cold air to accelerate the cooling and condensation of the steam.

[0156] In some embodiments, the air blower 530 is arranged at one side of the cover plate 520, and the air outlet of the air blower 530 is in communication with the air duct cavity.

[0158] In some embodiments, the connecting pipe 710 can be a metal hose, so as to effectively reduce the collision noise between the connecting pipe 710 and the support plate 510.

[0159] In some embodiments, the support plate 510 is provided with a mounting opening, and the connecting pipe 710 is inserted into the mounting opening, so as to facilitate the fixation of the position of the connecting pipe 710.

[0160] Figure 14 For Figure 13 The local enlarged view at E in FIG. 7A.

[0161] Referring to Figure 14 In some embodiments, the condensation structure 700 comprises a condensation pipe 720. The condensation pipe 720 is used to accelerate the condensation of the steam.

[0162] The condensation pipe 720 is connected with the connecting pipe 710. Specifically, the condensation pipe 720 and the connecting pipe 710 can be inserted or welded.

[0163] The condensation pipe 720 is provided with a plurality of openings 721, and the plurality of openings 721 are arranged at intervals.

[0164] It should be noted that, in order to effectively prevent the overflow of the condensed water from the openings 721, the openings 721 can be arranged at the upper part of the condensation pipe 720, for example, the top.

[0165] In some embodiments, the condensation pipe 720 is located in the air duct structure 500, and the extension direction of the condensation pipe 720 is parallel to the horizontal plane. It can be understood that, since the extension direction of the condensation pipe 720 is parallel to the horizontal plane, the flow speed of the condensed water in the condensation pipe 720 is small, and the flow of the steam is not easily hindered.

[0166] Specifically, the condensation pipe 720 is located in the air duct cavity.

[0167] Understandably, the steam in the inner liner 200 enters the condenser tube 720 via the connecting structure 600 and connecting pipe 710. Under the action of the cold air generated by the fan 530, the steam entering the condenser tube 720 is rapidly cooled, and some of the steam is converted into condensate, which remains in the condenser tube 720. The cooled steam is discharged into the air duct cavity through the opening 721 in the condenser tube 720 and blown to the outside of the steam oven by the airflow of the fan 530.

[0168] Since steam condenses into condensate and remains in the condenser pipe 720, when the water accumulates to a certain amount, it will flow back into the inner liner 200 through the connecting pipe 710 and the connecting structure 600, thus achieving the recycling of condensate. Because the connecting structure 600 is located at the bottom of the inner liner 200, compared to a top-mounted design, it effectively solves the problem of backflowing condensate contaminating food on the baking tray or grill.

[0169] In some embodiments, the condenser tube 720 can be a metal tube with good thermal conductivity, which has a good condensation effect on the discharged steam, thereby reducing the temperature of the discharged steam.

[0170] See Figure 14 As shown, in some embodiments, the condensation structure 700 includes a fastener 730. The fastener 730 is used to fix the position of the condenser tube 720.

[0171] The fastener 730 is located in the air duct structure 500 and is connected to the air duct structure 500. The condenser pipe 720 is connected to the fastener 730.

[0172] Specifically, the fastener 730 is located inside the air duct cavity and is connected to the cover plate 520.

[0173] In some embodiments, the fastener 730 may be connected to the cover plate 520 by screws, or it may be glued.

[0174] Figure 15 This is a schematic diagram of the structure of the condenser tube and fixing component in the steam oven provided in the embodiments of this application. Figure 16 for Figure 15 sectional view, Figure 17 This is a schematic diagram of the condenser tube in the steam oven provided in the embodiments of this application. Figure 18 This is a schematic diagram of the structure of the fixing component in the steam oven provided in the embodiment of this application.

[0175] See Figures 15 to 18 As shown, in some embodiments, the plurality of openings 721 include a plurality of first openings 7211 and a second opening 7212, wherein the plurality of first openings 7211 are spaced apart along the extending direction of the condenser tube 720. The second opening 7212 is located at the end of the condenser tube 720 opposite to the connecting tube 710.

[0176] In some embodiments, the fixing member 730 is provided with a third opening 731, which is in communication with the air duct cavity of the air duct structure 500 and the second opening 7212.

[0177] In this way, the steam can move from the end of the condensing pipe 720 away from the fixing member 730 to the end close to the fixing member 730 and escape from the fixing member 730, and the flow path is long, which is conducive to improving the condensation effect.

[0178] Referring to FIGS. 7 and 8, in some embodiments, the condensing pipe 720 is inserted into the fixing member 730. The condensing pipe 720 is in interference fit with the fixing member 730. Figure 15 Figure 16 Referring to FIGS. 7 and 8, in some embodiments, the condensing pipe 720 is inserted into the fixing member 730. The condensing pipe 720 is in interference fit with the fixing member 730.

[0179] In some embodiments, the fixing member 730 can be made of soft materials such as rubber.

[0180] Referring to FIGS. 7 and 8, in some embodiments, the condensing pipe 720 is inserted into the fixing member 730. The condensing pipe 720 is in interference fit with the fixing member 730. Figure 17 Figure 18 Referring to FIGS. 7 and 8, in some embodiments, the condensing pipe 720 is inserted into the fixing member 730. The condensing pipe 720 is in interference fit with the fixing member 730.

[0181] In some embodiments, one of the first positioning portion 722 and the second positioning portion 732 can be a protrusion, and the other can be a groove matched with the protrusion.

[0182] In some embodiments, the inner diameter of the connecting structure 600 is not less than 12 mm.

[0183] It can be understood that according to the formula flow rate = flow speed x cross-sectional area, the flow speed is inversely proportional to the cross-sectional area. If the inner diameter of the connecting structure 600 is less than 12 mm, the flow speed of the airflow after passing through the connecting structure 600 increases when the steam oven is working, which hinders the backflow of the condensed water, so that the condensed water cannot flow back to be collected, and in severe cases, the condensed water can be sprayed out of the opening of the condensing pipe 720.

[0184] In some embodiments, the inner diameter of the connecting structure 600 is 12 mm, 14 mm, 15 mm, 18 mm, 20 mm, or 25 mm, etc.

[0185] In some embodiments, the inner diameter of the connecting pipe 710 is not less than 12 mm.

[0186] In some embodiments, the inner diameter of the condensing pipe 720 is not less than 12 mm.

[0187] ​​In some embodiments, the third opening 731 and the sum of the opening areas of the plurality of first openings 7211 are greater than the cross-sectional area of the inner cavity of the connecting structure 600.

[0188] In some embodiments, the third opening 731 and the first opening 7211 have equal opening areas.

[0189] It should be noted that the opening area is the projected area of the region surrounded by the inner wall of the opening towards the horizontal plane.

[0190] It can be understood that the sum of the areas of the third opening 731 and the plurality of first openings 7211, i.e., the single opening area x the number of openings, should be greater than or equal to the cross-sectional area of the inner cavity of the connecting structure 600 in theory, otherwise, according to the relationship of flow rate = flow velocity x cross-sectional area, the sum of the areas of the third opening 731 and the plurality of first openings 7211 being too small will increase the flow velocity of the airflow, hindering the backflow of the condensed water.

[0191] It should be noted that the cross-sectional area of the inner cavity of the connecting structure 600 is the cross-sectional area perpendicular to the extension direction of the connecting structure 600.

[0192] Exemplarily, the diameter of the inner cavity of the connecting structure 600 is 12 mm, the diameter of the first opening 7211 and the third opening 731 is 4 mm, and considering the pressure loss in the actual condensation process, the number of openings should not be less than 7.

[0193] In some embodiments, the diameter of the inner cavity of the connecting structure 600 is 12 mm, the inner diameter of the condensing pipe 720 is 12 mm, the diameter of the first opening 7211 of the condensing pipe 720 is 4 mm, and the number of openings is 6. The diameter of the third opening 731 is 4 mm, and the number of the third opening 731 is one.
