Abstract
Description
Technical Field
[0001] This disclosure relates to the field of kitchen appliance technology, and more particularly to a steam oven. Background Technology
[0002] A steam oven uses water to generate steam inside its cavity, which is then used to bake food. Because steam ovens continuously produce steam during use, they typically have vents to release excess steam and balance the internal and external pressure.
[0003] In related technologies, steam ovens are equipped with a condensation chamber, where excess steam can enter and turn into condensate. However, the condensate may drip into the vent holes of the steam oven, posing a risk of condensate flowing back into the oven. Summary of the Invention
[0004] The purpose of this disclosure is to provide a steam oven that prevents condensate from falling into the vent hole of the steam oven's condensation chamber.
[0005] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions:
[0006] This disclosure provides a steam oven, which includes an inner liner, an exhaust pipe, a drip tray, a heat dissipation cover, and a support component. The exhaust pipe is located above the inner liner, with its first end communicating with the inner liner and its second end having an exhaust port. The drip tray is located above the exhaust pipe. The heat dissipation cover covers the drip tray. The heat dissipation cover and the drip tray form a condensation chamber; the exhaust port penetrates the drip tray and communicates with the condensation chamber. The support component is located between the inner liner and the heat dissipation cover; one end of the support component abuts against the heat dissipation cover, and the other end of the support component penetrates the drip tray and is fixedly connected to the inner liner. The support component supports the heat dissipation cover so that the orthographic projection of the bottom of the heat dissipation cover on the plane containing the heat dissipation cover does not overlap with the orthographic projection of the exhaust pipe.
[0007] The steam oven provided in this application embodiment features a drip tray and a heat dissipation cover, which together form a condensation chamber. Steam from the exhaust vent condenses into water droplets upon contact with the condenser and is stored in the drip tray. This prevents steam from directly escaping to the outside, thus avoiding scalding the user. It also prevents condensation from dripping onto the user's cabinets, preventing cabinet contamination and kitchen dampness. Furthermore, the support components support the heat dissipation cover, forcibly repositioning it and reducing its recessed area. The projection of the recessed area does not overlap with the projection of the exhaust vent. Even if a recessed area remains, condensation dripping from it will not directly enter the exhaust vent, preventing backflow of condensation into the inner cavity and affecting the taste of the food.
[0008] In some embodiments, the steam oven further includes a water separation bracket located on the drip tray; the vent penetrates the water separation bracket and communicates with the condensation chamber, and the vent is positioned higher than the bottom of the drip tray. The support member also penetrates the water separation bracket to fix the water separation bracket to the drip tray.
[0009] In some embodiments, the steam oven further includes a liner disposed on the water separation bracket, and the support member extends through the liner.
[0010] In some embodiments, the width of the water separation support is smaller than the width of the water droplet.
[0011] In some embodiments, the number of support members is multiple, and the exhaust port is located between two of the support members.
[0012] In some embodiments, the heat dissipation cover is provided with a through hole, through which the condensation chamber communicates with the outside. The steam oven also includes a heating component located at the bottom of the drip tray, which heats the condensate in the drip tray to accelerate the evaporation rate of the condensate.
[0013] In some embodiments, the steam oven further includes a temperature sensor and a controller. The temperature sensor, disposed on the drip tray, detects the temperature on the drip tray and outputs a sensing signal. The controller, coupled to both the temperature sensor and the heating element, receives the sensing signal from the temperature sensor and controls the operating state of the heating element based on the sensing signal.
[0014] In some embodiments, the number of temperature sensors is multiple, and the multiple temperature sensors are used to detect the temperature at different locations on the water receiving tray and output sensing signals.
[0015] The heating assembly includes a heating wire and a switching component. The heating wire, coupled to the controller, generates heat during operation. The switching component is connected in series with the heating wire; the switching component is coupled to the controller, which further controls the on / off state of the switching component based on the sensing signal.
[0016] In some embodiments, the steam oven further includes a fan assembly located above the drip tray; the fan assembly has an air duct communicating with the outside, and the fan assembly is used to exhaust gas in the air duct to the outside. The heat dissipation cover plate forms part of the air duct, and the heat dissipation cover plate is provided with through holes, through which the condensation chamber communicates with the interior of the air duct.
[0017] In some embodiments, the steam oven further includes a water tank, a water inlet pipe, a power unit, a steam generator, a water-vapor separator, and an air inlet pipe. The water tank is located above the inner liner. A first end of the water inlet pipe is connected to the water tank. The power unit is mounted on the water inlet pipe and is used to drive the liquid flow within the water inlet pipe. The inlet of the steam generator is connected to a second end of the water inlet pipe. The inlet of the water-vapor separator is connected to the outlet of the steam generator, and the first outlet of the water-vapor separator is connected to the inlet of the steam generator, forming a communicating vessel with the steam generator. One end of the air inlet pipe is connected to a second outlet of the steam generator, and the other end is connected to the inner liner. Attached Figure Description

[0046] like Figure 1 As shown, this embodiment of the present disclosure provides a steam oven 100, which includes a housing 1.
[0047] The housing 1 is used to protect the components located inside the housing 1.
[0048] For example, the material of the housing 1 includes metal and glass.
[0049] Metal has high strength, which can better protect the components located inside the outer casing 1. Furthermore, metal has a better texture; when the outer casing 1 is made of metal, it can enhance the overall quality of the steam oven 100 and improve the user experience.
[0050] Glass is easier to clean, making it easier to remove stains. Including glass in the outer casing 1 improves the ease of cleaning the steam oven 100 and reduces the difficulty of cleaning it.
[0051] For example, the outer casing 1 includes an inner cavity for placing food ingredients.
[0052] For example, such as Figure 1 As shown, the outer casing 1 includes an oven door 1a.
[0053] For example, the oven door 1a is hinged to other parts of the housing 1, thereby facilitating the opening and closing of the oven door 1a.
[0054] For example, the oven door 1a can be made of glass, so that the state of the food inside can be seen through the oven door 1a, which is helpful to control the working state of the steam oven 100 according to the state of the food.
[0055] For example, such as Figure 1 As shown, the oven door 1a includes a handle, which facilitates operation of the oven door 1a.
[0056] For example, the housing 1 includes a control panel 1b.
[0057] Control panel 1b is used to control steam oven 100.
[0058] For example, such as Figure 1 As shown, the control panel 1b and the oven door 1a are located on the same side of the steam oven 100, which makes it convenient for the user to adjust the control panel 1b.
[0059] like Figure 2 As shown, the steam oven 100 includes an inner cavity 2, which together with the oven door 1a forms the cooking cavity of the steam oven 100. The cooking cavity is used to form a space for placing food.
[0060] The oven door 1a is used to open or close the cooking cavity. When food needs to be cooked, use the oven door 1a to open the cooking cavity, then place the food to be cooked into the cooking cavity, and then use the oven door 1a to close the cooking cavity. Start the steam oven to cook the food, and then take the food out after cooking.
[0061] For example, such as Figure 2 As shown, the steam oven 100 can be equipped with a shelf, which is installed inside the inner cavity 2 and fixedly connected to the inner cavity 2. The shelf is used to place food.
[0062] For example, such as Figure 3As shown, the steam oven 100 also includes a water storage tank 3, a water inlet pipe 4, a power unit 5, a steam generator 6, a water-steam separator 7, and an air inlet pipe 8.
[0063] For example, the water tank 3 is located above the inner liner. The water tank 3 is used to store clean water for generating steam. By setting the water tank 3, it is possible to avoid frequently adding water to the steam oven 100, which helps to improve the ease of use of the steam oven 100.
[0064] For example, the first end of the water inlet pipe 4 is connected to the water storage tank 3. The clean water stored in the water storage tank 3 can be drawn out through the water inlet pipe 4.
[0065] For example, the power unit 5 is provided on the water inlet pipe 4 to drive the flow of liquid in the water inlet pipe 4.
[0066] For example, power component 5 can be a water pump.
[0067] For example, the inlet of the steam generator 6 is connected to the second end of the water inlet pipe 4. Therefore, clean water stored in the water storage tank 3 can flow into the steam generator 6 through the water inlet pipe 4.
[0068] For example, the steam generator 6 can turn the water inside the steam generator 6 into steam by heating.
[0069] For example, the inlet of the water vapor separator 7 is connected to the outlet of the steam generator 6, and the first outlet of the water vapor separator 7 is connected to the inlet of the steam generator 6, thus forming a communicating vessel with the steam generator 6.
[0070] For example, the water vapor separator 7 can separate the gas-liquid mixture flowing into it, return the separated liquid to the steam generator 6 to continue converting the liquid into steam, and transfer the separated steam to the inner tank.
[0071] For example, one end of the air inlet pipe 8 is connected to the second outlet of the steam generator 6, and the other end of the air inlet pipe 8 is connected to the inner liner 2.
[0072] For example, the steam separated by the water vapor separator 7 can be introduced into the inner pot 2 through the air inlet pipe 8 to cook the food inside the inner pot 2.
[0073] With the above settings, when cooking food, the power unit 5 is turned on first, and the water in the water tank 3 enters the steam generator 6 and the water-steam separator 7 through the water inlet pipe 4. The water level in the steam generator 6 and the water level in the water-steam separator 7 are equal. Under the action of the steam generator 6, the steam first enters the water-steam separator 7 through the inlet of the water-steam separator 7. Then, during the steam flow, the cooled water droplets fall into the water-steam separator 7. Finally, the dry steam enters the inner pot 2 (not shown in the figure) through the second outlet of the water-steam separator 7 and the air inlet pipe 8 to cook the food in the inner pot 2.
[0074] For example, the steam oven 100 also includes a water return pump. After cooking, activating the water return pump can extract the remaining water in the steam generator 6 and the water separator 7 into the water storage tank 3, thereby achieving water recycling.
[0075] In addition, due to the presence of the water vapor separator 7, the moisture in the steam can be cooled and stored in the water vapor separator 7, while the steam entering the inner pot 2 is dry steam. This can prevent the food from being wet on the surface after cooking, thus making the cooking effect better.
[0076] In some examples,
[0077] After cooking is finished, the cooking cavity will still be filled with high-temperature steam before the oven door 1a is opened. If the oven door 1a is turned directly at this time to open the cooking cavity, the high-temperature steam in the cooking cavity will be directly released, which may easily cause the operator to be burned.
[0078] Therefore, in related technologies, an exhaust pipe is installed between the inner liner and the outer shell, and an exhaust hole is opened on the inner liner. One end of the exhaust pipe connects to the exhaust hole, and the other end connects to the outside of the outer shell, allowing steam from the inner liner to be discharged to the outside of the shell. This is to prevent users from being scalded by high-temperature steam when opening the steam oven door. However, the high-temperature steam easily condenses at the second end of the exhaust pipe after being discharged. This condensate dripping can cause staining of the user's cabinets and a damp kitchen. Furthermore, the temperature of the steam discharged from the second end of the exhaust pipe is still relatively high, which can easily cause injury to the user.
[0079] In another implementation, for larger-capacity steam ovens, due to the larger space, a condensation structure can be installed. This allows high-temperature steam to condense and be guided to the bottom of the inner cavity, where it will then re-evaporate to form steam. However, this method can easily lead to excessive water accumulation inside the inner cavity, posing a risk of overflow. After use, the evaporation plate at the bottom of the inner cavity needs to be turned on for drying, or the user needs to manually clean the condensate from the bottom of the inner cavity. This increases energy consumption and cleaning time. Furthermore, the use of a water pump to guide the condensate from the condensation structure into the inner cavity inevitably causes noise, which users may question or even attribute to a quality issue.
[0080] Based on this, combined Figures 4-9 The steam oven 100 provided in this application embodiment includes an exhaust pipe 9, a water receiving tray 10, a heat dissipation cover plate 11, and a support component 12.
[0081] In some examples, such as Figure 4 As shown, the exhaust pipe 9 is located above the inner liner 2, and the first end of the exhaust pipe 9 is connected to the inner liner 2, as shown. Figure 12 As shown, an exhaust port 9A is provided at the second end of the exhaust pipe 9.
[0082] The temperature of steam is relatively high. Therefore, in the steam oven 100, most of the steam is concentrated above the inner liner 2. By setting the exhaust pipe 9 above the inner liner 2, the steam can be discharged through the exhaust pipe 9 as quickly as possible.
[0083] For example, there can be one or more exhaust pipes 9. When there are multiple exhaust pipes 9, the exhaust speed of steam inside the inner liner 2 can be accelerated.
[0084] For example, an exhaust pipe 9 is provided with an exhaust port 9A, and the number of exhaust ports 9A can be set to correspond to the number of exhaust pipes 9.
[0085] For example, the number of exhaust pipes 9 is one, and the number of exhaust ports 9A is one; the number of exhaust pipes 9 is two, and the number of exhaust ports 9A is two; the number of exhaust pipes 9 is three, and the number of exhaust ports 9A is three; or the number of exhaust pipes 9 and the number of exhaust ports 9A can be other numbers, which are not limited in this application.
[0086] Understandably, a single exhaust pipe 9 can also have multiple exhaust ports 9A.
[0087] In some examples, combined Figure 6 and Figure 7 The water collection tray 10 is located above the exhaust pipe 9. A heat dissipation cover 11 covers the water collection tray 10. Figure 8 , Figure 9 , Figure 10 and Figure 11 The heat dissipation cover 11 and the water receiving tray 10 form a condensation chamber Q. The exhaust port 9A passes through the water receiving tray 10 and communicates with the condensation chamber Q.
[0088] For example, the drip tray 10 is made of a metal material with good thermal conductivity. The heat dissipation cover 11 is also made of a metal material with good thermal conductivity. After the heat dissipation cover 11 and the drip tray 10 form a condensation chamber Q, the steam from the exhaust port 9A will condense into water droplets upon contact with the condensation and be stored in the drip tray 10. This prevents the steam inside the steam oven 100 from being directly discharged to the outside, thus avoiding burns to the user from high-temperature steam. It also prevents the high-temperature steam from directly discharging and forming condensate droplets that fall onto the user's cabinet, thus avoiding staining of the user's cabinet and dampness in the kitchen.
[0089] Compared to the other implementation method mentioned above, this method also avoids the risk of excessive water overflowing from the inner tank. Furthermore, the condensate can be directly stored in the condensation chamber Q without needing to be diverted elsewhere, thus eliminating the need for a separate water pump and avoiding noise issues associated with water pumps, thereby improving the user experience.
[0090] In some examples, such as Figure 12 As shown, the support member 12 is located between the inner liner 2 and the heat dissipation cover 11. One end of the support member 12 abuts against the heat dissipation cover 11, and the other end of the support member 12 passes through the water receiving tray 10 and is fixedly connected to the inner liner 2. The support member 12 is used to support the heat dissipation cover 11 so that the orthographic projection of the recessed area of the heat dissipation cover 11 on the plane where the heat dissipation cover 11 is located does not overlap with the orthographic projection of the exhaust port 9A.
[0091] For example, on the plane where the heat sink cover 11 is located, the orthographic projection of the recessed area of the heat sink cover 11 and the orthographic projection of the exhaust port 9A do not overlap, indicating that the recessed area of the heat sink cover 11 and the exhaust port 9A are offset from each other.
[0092] Understandably, after the heat dissipation cover 11 is placed over the water receiving tray 10, due to its own weight, the heat dissipation cover 11 will have a certain indentation, and the indentation area is generally located near the center of the heat dissipation cover 11. Combined with... Figure 12 The steam discharged from the exhaust port 9A condenses into water droplets, which adhere to the heat dissipation cover 11. If the heat dissipation cover 11 has a recessed area, these condensed water droplets will flow along the cover 11 and drip down into the recessed area. This condensed water dripping from the recessed area may directly drip into the exhaust port 9A and then into the inner liner 2 along the exhaust pipe 9, causing continuous dripping into the inner liner 2. This could result in the condensed water dripping onto the food, affecting its texture.
[0093] In this embodiment, by providing a support member 12, the heat dissipation cover 11 can be supported, thereby forcibly resetting the heat dissipation cover 11, reducing the recessed area on the heat dissipation cover 11, and ensuring that the orthographic projection of the recessed area of the heat dissipation cover 11 does not overlap with the orthographic projection of the exhaust port 9A. In this way, even if there is still a recessed area on the heat dissipation cover 11, it can prevent condensate from dripping into the exhaust port 9A directly after entering the recessed area, thereby preventing condensate from flowing back into the inner liner 2 and affecting the taste of the food.
[0094] In addition, when the heat dissipation cover 11 is formed by welding, the support member 12 can also support the depression formed by welding stress on the heat dissipation cover 11, and can also prevent condensate from dripping directly into the exhaust port 9A.
[0095] Therefore, the steam oven 100 provided in this embodiment of the application, by setting a water tray 10 and a heat dissipation cover 11, and forming a condensation chamber with the water tray 10 and the heat dissipation cover 11, will cause the steam from the exhaust port 9A to condense into water droplets upon contact with the condensation and be stored in the water tray 10. This prevents the steam inside the steam oven 100 from being directly discharged to the outside, thus avoiding scalding the user with high-temperature steam. It also prevents the high-temperature steam from being directly discharged and forming condensate droplets that fall onto the user's cabinet, thus avoiding cabinet contamination and kitchen dampness. Furthermore, by setting a support component 12, the heat dissipation cover 11 can be supported to force the heat dissipation cover 11 to be reset, reducing the recessed area on the heat dissipation cover 11, and ensuring that the orthographic projection of the recessed area of the heat dissipation cover 11 does not overlap with the orthographic projection of the exhaust port 9A. In this way, even if there is still a recessed area on the heat dissipation cover 11, it can prevent condensate from dripping into the recessed area and directly entering the exhaust port 9A, thereby preventing condensate from flowing back into the inner cavity 2 and affecting the taste of the food.
[0096] In some embodiments, such as Figure 10 , Figure 11 and Figure 12 As shown, the steam oven 100 also includes a water separation bracket 13 located on the drip tray 10. An exhaust port 9A penetrates the water separation bracket 13 and communicates with the condensation chamber Q; the exhaust port 9A is positioned higher than the bottom of the drip tray 10. A support member 12 also penetrates the water separation bracket 13 to fix the water separation bracket 13 to the drip tray 10.
[0097] For example, such as Figure 12 As shown, the water separation bracket 13 is provided with a through hole, the size of which is larger than the outer diameter of the exhaust pipe 9, so that the exhaust pipe 9 can pass through the through hole and the exhaust port 9A can discharge steam into the condensation chamber Q.
[0098] Or, such as Figure 13 As shown, the through hole size of the water separation bracket 13 is the same as the inner diameter size of the exhaust pipe 9, which can also ensure that the steam in the exhaust pipe 9 is discharged normally.
[0099] For example, the material of the water separation bracket 13 may include metal and heat-resistant plastic.
[0100] For example, the thickness of the water separation bracket 13 can range from 0.4 mm to 1.5 mm.
[0101] For example, the thickness of the water separation bracket 13 can be 0.4mm, 0.8mm, 1.0mm, 1.2mm or 1.5mm, etc.
[0102] The water separation bracket 13 has a certain height. After the vent 9A passes through the water separation bracket 13 and connects to the condensation chamber Q, the vent 9A is located at the upper part of the water separation bracket 13. This ensures that the position of the vent 9A is higher than the bottom of the water receiving tray 10. When there is a lot of condensate in the condensation chamber Q, the liquid level of the condensate in the condensation chamber Q will rise. Through the above arrangement, the vent 9A is positioned higher, which can prevent the condensate from flowing back into the inner liner 2 through the vent 9A even after the liquid level rises due to the large amount of condensate in the condensation chamber Q. This prevents the condensate from flowing back into the inner liner 2 and affecting the taste of the food.
[0103] In some examples, the area of the water separation bracket 13 is small, which can prevent condensate from accumulating in the water separation bracket 13 and eventually flowing into the inner liner 2 through the vent 9A.
[0104] For example, the width of the water separation bracket 13 may be smaller than the width of the water droplet.
[0105] With the above settings, water droplets can be prevented from forming on the water separation bracket 13, thereby preventing condensate from accumulating on the water separation bracket 13 and eventually flowing into the inner liner 2 through the vent 9A.
[0106] In some embodiments, such as Figures 11-13 As shown, the steam oven 100 also includes a liner 14 disposed on the water separation bracket 13, and the support member 12 extends through the liner 14.
[0107] For example, liner 14 may include a gasket.
[0108] When the liner 14 is a gasket, the connection between the support member 12 and the water separation bracket 13 can be strengthened, and the support member 12 can be prevented from damaging the surface of the water separation bracket 13.
[0109] For example, the number of pads 14 can be one or more.
[0110] For example, such as Figures 11-13 As shown, the pad 14 can elevate the water separation bracket 13, allowing the support component 12 to be closer to the heat dissipation cover 11.
[0111] The distance between the support component 12 and the heat dissipation cover 11 can be adjusted by adjusting the number of pads 14.
[0112] For example, when the distance between the support member 12 and the heat dissipation cover 11 is relatively short, a smaller number of pads 14 can be used to achieve mutual contact between the support member 12 and the heat dissipation cover 11. When the distance between the support member 12 and the heat dissipation cover 11 is relatively long, a larger number of pads 14 can be used to ensure mutual contact between the support member 12 and the heat dissipation cover 11.
[0113] With the above settings, the distance between the support component 12 and the heat dissipation cover plate 11 can be adjusted by adjusting the number of pads 14, so that the support component 12 and the heat dissipation cover plate 11 abut against each other, and the support component 12 supports the heat dissipation cover plate 11, so that the recessed area of the heat dissipation cover plate 11 is staggered from the exhaust port 9A, and prevents condensate from dripping into the exhaust port 9A and entering the inner liner 2 after dripping from the recessed area of the heat dissipation cover plate 11.
[0114] In some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, there are multiple support components 12, and the exhaust port 9A is located between two support components 12.
[0115] For example, the number of support components 12 can be two, three, or four, etc.
[0116] Figure 11 , Figure 12 and Figure 13 Three support components 12 are shown in the middle.
[0117] The support member 12 can support the position where it abuts against the heat dissipation cover 11. Therefore, when there are two support members 12, the area of the heat dissipation cover 11 between the two support members 12 will be lifted up, thus preventing the formation of a depression in the aforementioned area and preventing condensation from dripping from the area between the two support members 12. When the vent 9A is positioned between the two support members 12, it can prevent condensation from dripping directly into the vent 9A, thereby preventing condensation from entering the inner liner 2 and affecting the taste of the food.
[0118] In some embodiments, such as Figure 9 As shown, the heat dissipation cover 11 has a through hole 11A, through which the condensation chamber Q communicates with the outside. Combined with... Figure 9 , Figure 14 and Figure 15The steam oven 100 also includes a heating element 15, which is located at the bottom of the drip tray 10. The heating element 15 is used to heat the condensate in the drip tray 10 to accelerate the evaporation rate of the condensate in the drip tray 10.
[0119] For example, the number of through holes 11A can be one or more.
[0120] For example, such as Figure 9 As shown, the heat dissipation cover 11 has multiple through holes 11A.
[0121] For example, the through hole 11A can be rectangular in shape with a small width, which can avoid forming a large gap on the heat sink cover 11 and affecting the strength of the heat sink cover 11.
[0122] By providing through holes 11A on the heat dissipation cover 11, the condensate in the condensation chamber Q can be evaporated into water vapor and then evaporated to the outside through the through holes 11A. This prevents excessive condensate in the condensation chamber Q and avoids condensate flowing back into the inner liner 2 from the exhaust port 9A, thus preventing it from affecting the taste of the food.
[0123] For example, the heating component 15 can be a heating film.
[0124] The heating film is a structure in which heating wires are coiled, which can make the heating component 15 heat the condensate in the water pan 10 more evenly and avoid the user from being scalded by high temperature steam in a certain position.
[0125] For example, the heating component 15 can be attached to the bottom of the drip tray 10 with an adhesive.
[0126] The heating component 15 generates high temperature during operation. After the heating component 15 is placed at the bottom of the water receiving tray 10, the high temperature can heat the condensate in the water receiving tray 10, thereby accelerating the evaporation rate of the condensate and removing the condensate in the water receiving tray 10 more quickly. Therefore, it can prevent too much condensate in the condensation chamber Q.
[0127] For example, when there is a large amount of condensate in the condensation chamber Q, the heating component 15 can be activated to accelerate the evaporation rate of the condensate. When there is a small amount of condensate in the condensation chamber Q, the heating component 15 can be turned off, and the condensate can be allowed to evaporate naturally.
[0128] For example, during the heating phase of the steam oven 100, the amount of steam inside the steam oven 100 is relatively large. At this time, the heating element 15 can be stopped from working. This ensures that the steam oven 100 does not emit a large amount of obvious steam during operation, which is beneficial to improving the user experience.
[0129] For example, after the steam oven 100 finishes operating, the heating component 15 will continue to operate for a period of time to ensure that as much condensate as possible can be removed from the condensation chamber Q.
[0130] With the above settings, the condensate in the condensation chamber Q can be heated to accelerate the evaporation rate of the condensate. This can prevent excessive condensate from being stored in the condensation chamber Q and flowing back into the inner liner 2, thus avoiding affecting the taste of the food.
[0131] In some embodiments, the steam oven 100 further includes a heat-conducting plate with good thermal conductivity. After the heating component 15 generates high temperature, it can quickly conduct the high temperature to the water tray 10, thereby accelerating the heating speed of the heating component 15 on the condensate in the water tray 10.
[0132] In some embodiments, such as Figure 14 As shown, the steam oven 100 also includes a temperature sensor 16 and a controller 17. The temperature sensor 16 is disposed on the water receiving pan 10 and is used to detect the temperature on the water receiving pan 10 and output a sensing signal. The controller 17 is coupled to the temperature sensor 16 and the heating element 15 respectively, and is used to receive the sensing signal from the temperature sensor 16 and control the working state of the heating element 15 according to the sensing signal.
[0133] For example, the temperature sensor 16 can be a thermocouple or the like.
[0134] For example, controller 17 may include a programmable logic controller (PLC) or the like.
[0135] For example, when the temperature sensor 16 detects that the temperature on the drip tray 10 is high, that is, the temperature of the condensate in the drip tray 10 is high, there may be a risk of generating high-temperature steam. The controller 17 can control the heating component 15 to stop working or reduce the heating power, thereby avoiding the user from being scalded by high-temperature steam due to excessively high condensate temperature.
[0136] For example, when the temperature sensor 16 detects that the temperature on the drip tray 10 is low, that is, the temperature of the condensate in the drip tray 10 is low, which may cause the condensate to evaporate slowly, the controller 17 can control the heating component 15 to start working or increase the heating power, thereby avoiding the condensate from evaporating slowly due to the low temperature of the condensate.
[0137] By setting the controller 17 to control the working state of the heating component 15 according to the sensing signal, the condensate in the condensation chamber Q can be kept at a suitable temperature, ensuring the evaporation rate of the condensate and avoiding the generation of high-temperature steam that could scald the user.
[0138] If the drip tray 10 is not placed completely horizontally, the bottom of the condensation chamber Q may tilt, resulting in uneven distribution of condensate within the drip tray 10, and condensate may only be present in certain areas of the drip tray 10. If the heating element 15 is activated under these conditions, it may cause localized high temperatures within the drip tray 10, or even lead to the heating element 15 burning out and being damaged.
[0139] Therefore, in some embodiments, such as Figure 14 As shown, there are multiple temperature sensors 16, which are used to detect the temperature at different locations on the water receiving tray 10 and output sensing signals. Figure 16 As shown, the heating assembly 15 includes a heating wire 18 and a switching component 19. The heating wire 18 is coupled to a controller 17 and is used to generate heat during operation. The switching component 19 is connected in series with the heating wire 18. The switching component 19 is coupled to the controller 17, which is also used to control the on / off state of the switching component 19 according to a sensing signal.
[0140] For example, the number of temperature sensors 16 can be two, three, or four, etc. Figure 14 Two temperature sensors 16 are shown in the figure.
[0141] For example, multiple temperature sensors 16 are disposed at different locations on the water receiving pan 10, thereby enabling the multiple temperature sensors 16 to detect the temperature at different locations on the water receiving pan 10.
[0142] For example, the heating wire 18 may include a resistance wire, etc.
[0143] For example, the switching component 19 may include a circuit breaker, etc.
[0144] For example, such as Figure 16 As shown, the number of switch components 19 can be two.
[0145] By connecting the switch component 19 in series with the heating wire 18, the heating wire 18 will not work when the switch component 19 is turned off.
[0146] For example, after the highest and lowest temperatures detected by multiple temperature sensors 16 exceed the limit values, the controller 17 can control the switch component 19 to be in the off state, thereby stopping the heating wire 18 from working. Therefore, the heating component 15 can be prevented from being damaged by dry burning.
[0147] In some embodiments, such as Figure 17 and Figure 18 As shown, Figure 17 This is a top view of the steam oven 100. Figure 18 for Figure 17In the cross-sectional view along line AA, the steam oven 100 also includes a fan assembly 20, which is located above the drip tray 10. The fan assembly 20 has an air duct 21 communicating with the outside, and is used to exhaust the gas in the air duct 21 to the outside. A heat dissipation cover 11 forms part of the air duct 21, and a through hole 11A is provided on the heat dissipation cover 11. The condensation chamber Q communicates with the interior of the air duct 21 through the through hole 11A.
[0148] For example, the vapor from the evaporation of condensate in the condensing chamber Q can diffuse into the air duct 21 through the through hole 11A. After the fan assembly 20 is installed, the fan assembly 20 can discharge the vapor to the outside, thereby accelerating the evaporation rate of the condensate in the condensing chamber Q. Figure 19 As shown, a notch is provided on the outer casing 1, such as Figure 20 As shown, the air inside the air duct 21 can be blown out from the opening in the outer casing 1.
[0149] In addition, the fan assembly 20 can draw in external air and blow it into the air duct 21. The external air temperature is low, and the aforementioned low-temperature air can cool the heat dissipation cover 11, thereby maintaining the low temperature state of the heat dissipation cover 11. This is beneficial for the high-temperature steam in the inner liner 2 to liquefy quickly after encountering the heat dissipation cover 11, thereby reducing the steam content discharged from the through hole 11A of the heat dissipation cover 11 into the air duct 21. Therefore, the moisture content of the steam blown out by the fan assembly 20 to the outside can be reduced, and the problem of a large amount of steam being discharged, causing the kitchen air to be humid or water vapor to condense and drip on the outside of the steam oven 100 will not be caused.
