Description

Technical Field

[0001] The utility model relates to the field of kitchen equipment, in particular to a steam oven. Background Art

[0002] The steam oven may include a housing and an inner container, wherein a cooking cavity is provided in the inner container, and food to be cooked is placed in the cooking cavity to cook the food.

[0003] The steam oven also includes a heat dissipation duct and a heat dissipation fan. The fan can drive the flow of air to dissipate the heat of the steam oven.

[0004] Currently, some steam ovens on the market often overcook food, significantly reducing its flavor. This not only wastes ingredients but also creates significant safety hazards. To detect the doneness of food, some steam ovens are equipped with cameras, but this results in higher costs and a more complex identification process. Some steam ovens are also equipped with oxygen sensors to address the need for detecting the doneness of some pastry ingredients, but the doneness of meat cannot be detected. Some steam ovens are equipped with odor sensors, but these are placed inside the air duct. During operation, the fan draws air from outside the inner tank into the air duct and then exhausts the air inside the air duct, resulting in a low odor concentration of the food in the air duct. Although the odor can be detected, the accuracy of the doneness detection is poor, making it easy to misjudge. Therefore, the present application proposes a steam oven. Summary of the Invention

The cooling channel may be arranged along the length of the housing.

[0118] The cooling channel can be located in front of the first fan. The space in front of the first fan is relatively large, which facilitates the arrangement of the cooling channel.

A drying chamber may be formed within the drying housing. The drying chamber is connected between the cooking chamber and the odor detection chamber along the direction of air flow within the air guide. The drying element may include a desiccant. The desiccant may be disposed within the drying chamber to dry the air flowing through the drying chamber, thereby reducing the humidity of the air flowing into the odor detection chamber and preventing high humidity from reducing the detection accuracy of the odor detection device.

[0120] In the present application, one end of the second air duct may be connected to the switch valve, and the other end of the second air duct may be connected to the drying element.

[0121] In this application, reference is made to Figure 15-16 The liner may include an liner rear wall 22. The liner rear wall may be located at the rear end of the liner.

[0122] refer to Figure 15-16 The steam oven 100 may include an air duct cover 81. The air duct cover 81 may be disposed within the inner container. The air duct cover 81 may be disposed in front of the rear wall of the inner container. The air duct cover 81 and the rear wall of the inner container may define a fan cavity 82. The fan cavity may be located behind the cooking cavity.

[0123] A fan cavity air inlet 811 may be formed on the air duct cover 81. The fan cavity air inlet may connect the cooking cavity and the fan cavity, so that the fan cavity air inlet is an entrance for the air in the cooking cavity to enter the fan cavity.

[0124] A fan cavity air outlet 812 may be formed on the air duct cover 81. The fan cavity air outlet 812 may connect the cooking cavity and the fan cavity, so that the fan cavity air outlet 812 is an outlet for the air in the fan cavity to flow out into the cooking cavity.

[0125] refer to Figure 15-16The steam oven 100 may include a second fan 83. The second fan 83 may be disposed in the fan cavity to drive the air in the cooking cavity to flow into the fan cavity through the fan cavity air inlet and then flow back to the cooking cavity through the fan cavity air outlet, thereby forming an air circulation.

[0126] The second blower 83 may include a second fan and a second motor.

[0127] The second motor can be connected to the second fan to drive the second fan to rotate. The second motor drives the second fan to rotate to drive the air in the cooking cavity to flow into the fan cavity through the fan cavity air inlet and then flow back to the cooking cavity through the fan cavity air outlet.

[0128] Setting up a second fan can establish air circulation between the fan cavity and the cooking cavity, making the air temperature and humidity in each location in the cooking cavity and the fan cavity relatively uniform, avoiding large temperature or humidity differences between two locations that are far apart, and avoiding uneven cooking caused by large temperature differences.

[0129] In the present application, the second fan may be a centrifugal fan. The centrifugal fan may be disposed opposite the fan chamber air inlet. Air within the cooking chamber may enter the centrifugal fan through the fan chamber air inlet along the axial direction of the centrifugal fan and then flow out of the centrifugal fan along the radial direction of the centrifugal fan.

[0130] In this application, reference is made to Figure 17-18 A cooking cavity air outlet 52 is formed on the air duct cover. The cooking cavity air outlet is communicated with the cooking cavity.

[0131] When the odor detection cavity is communicated with the cooking cavity, the cooking cavity air outlet may be communicated with the odor detection cavity, so that the air in the cooking cavity may flow into the odor detection cavity through the cooking cavity air outlet.

[0132] The cooking cavity air outlet is arranged on the air duct cover plate, which can be directly connected to the cooking cavity, ensuring that the smell of the food in the odor detection cavity is strong, and can better produce the induced effect, so that when the first fan rotates, the gas in the cooking cavity can be introduced into the odor detection cavity, and the air is prevented from flowing back into the cooking cavity from the air duct. The air guide member guides the air from the rear of the inner pot to the top of the inner pot, so that the air flow path in the air guide member is longer, which is convenient for air heat dissipation, better enhances heat dissipation, and avoids the high air temperature from affecting the odor detection device.

[0133] In this application, reference is made to Figure 17-18 The inner pot includes an inner pot top wall 23. The inner pot top wall 23 can be arranged at the top of the inner pot. A cooking cavity air outlet is formed on the inner pot top wall. The cooking cavity air outlet is connected to the cooking cavity.

[0134] When the odor detection cavity is communicated with the cooking cavity, the cooking cavity air outlet may be communicated with the odor detection cavity, so that the air in the cooking cavity may flow into the odor detection cavity through the cooking cavity air outlet.

[0135] The cooking cavity air outlet is set on the top wall of the inner pot, which can be directly connected to the cooking cavity, ensuring that the smell of the food in the odor detection cavity is strong, and can better produce an induced effect, so that when the first fan rotates, the gas in the cooking cavity can be introduced into the odor detection cavity, and the air is prevented from flowing back into the cooking cavity from the air duct.

[0136] In this application, reference is made to Figure 17-18 The air guide may include an adapter 66. A transfer channel 661 may be formed in the adapter 66. An adapter air inlet 662 may be formed on the adapter. The adapter air inlet 662 may be in communication with the transfer channel 661.

[0137] When the odor detection chamber and the cooking chamber are connected, the transfer channel can be connected to the odor detection chamber. The adapter air inlet can be arranged opposite to the cooking chamber air outlet, and the adapter air inlet can be connected to the cooking chamber air outlet, so that air in the cooking chamber can enter the transfer channel through the cooking chamber air outlet and the adapter air inlet, and then flow into the odor detection chamber.

[0138] In this application, reference is made to Figure 17-18 The adapter may include a third air duct 67. One end of the third air duct may be connected to the drying element, and the other end of the third air duct may be connected to the adapter.

[0139] A third air guiding channel may be formed in the third air guiding tube, and the third air guiding channel may connect the transfer channel and the drying chamber.

[0140] In the present application, when the cooking cavity air outlet is disposed on the air duct cover, the adapter can be disposed behind the air duct cover, and an adapter air inlet can be formed at the front end of the adapter, which can abut against the air duct cover. The front end of the adapter and the air duct cover can be sealed, allowing air from the cooking cavity air outlet to enter the adapter channel, thereby preventing air leakage.

[0141] refer to Figure 17-18 The adapter can be at least partially disposed in the fan cavity. A third through hole 221 can be formed on the rear wall of the inner container. The third through hole can connect the fan cavity with the space outside the inner container.

[0142] The adapter is inserted into the third through hole, or the third air duct can be inserted into the third through hole, or both the adapter and the third air duct are inserted into the third through hole, which is convenient for setting the adapter and connecting the adapter and the third air duct.

[0143] The rear end of the adapter can be inserted into the third air duct, and the connection structure is simple and easy to set up.

[0144] In the present application, the drying element can be arranged vertically so that the desiccant in the drying element can be concentrated at the bottom of the drying chamber, so that all the gas passing through the drying chamber flows through the desiccant, which can dry the air and avoid the high air humidity from affecting the detection accuracy of the odor detection device.

[0145] When the drying element is connected to the third air duct, the drying element can be arranged behind the rear wall of the inner container, which can fully utilize the space behind the rear wall of the inner container and reasonably arrange the position of the drying element.

[0146] In the present application, when the cooking cavity air outlet is disposed on the top wall of the inner pot, the adapter can be disposed above the inner pot, and the bottom end of the adapter can be formed with an adapter air inlet, and the bottom end of the adapter can abut against the top wall of the inner pot. The bottom end of the adapter can be sealed to the top wall of the inner pot, so that the gas from the cooking cavity air outlet enters the adapter channel, thereby preventing air leakage.

[0147] In the present application, when the air outlet of the cooking cavity is arranged on the top wall of the inner pot, part of the third air duct can be arranged behind the rear wall of the inner pot, which can increase the flow path of the air in the air guide component, so that the air can be fully cooled, and it is convenient to vertically arrange the drying component behind the rear wall of the inner pot.

[0148] In the present application, along the air flow direction in the air guide, the drying element is located between the cooling channel and the cooking cavity. The drying element can be located at the rear of the inner pot.

[0149] The gas coming out of the cooking cavity has high humidity and high temperature. The drying element and the cooling channel are arranged between the odor detection cavity and the cooking cavity, so that the air can be dehumidified and cooled before reaching the odor detection cavity. The drying element is arranged at the rear of the inner pot, which can make full use of the space at the rear of the inner pot and avoid placing the drying element above the inner pot, which makes the height of the steam oven too large.

[0150] In the present application, along the direction of air flow in the air guide, the switch valve can be arranged between the drying element and the cooking cavity, so that when there is no need to detect the odor, the switch valve can be closed, which can prevent air from entering the drying element, prevent the drying element from working, and avoid wasting the drying element.

[0151] In the present application, along the direction of air flow in the air guide, the switch valve can be arranged between the drying element and the cooling channel, so that when there is no need to detect the odor, the switch valve can be closed, which can prevent air from entering the air duct and prevent the air duct from cooling the air and causing poor cooling effect on the surrounding area of ​​the inner tank.

[0152] In the present application, the switch valve can be arranged between the cooling channel and the odor detection chamber along the direction of air flow in the air guide, so that the gas in the cooling channel can flow into the switch valve only after the air duct cools down the gas, thereby avoiding the influence of excessive air temperature on the switch valve and avoiding the high air temperature reducing the service life of the switch valve.

[0153] In this application, the cooling channel is connected to the side of the odor detection chamber away from the air duct along the air flow direction within the air guide. The cooling channel can communicate with the odor detection chamber. The switch valve can connect or isolate the odor detection chamber and the cooling channel.

[0154] Along the air flow direction in the air guide, the drying element is connected between the cooling channel and the cooking cavity, and connects the cooling channel and the cooking cavity.

[0155] When the cooling channel is in communication with the odor detection chamber, the first fan rotates to allow the air in the cooking chamber to flow into the odor detection chamber through the drying element and the cooling channel and then into the air duct.

[0156] The drying element is arranged between the cooling channel and the cooking cavity. The temperature of the gas coming out of the cooking cavity is higher. Compared with drying the air after it is cooled, drying the air before it is cooled can achieve a better drying effect and avoid the influence of high air humidity on the detection accuracy of the odor detection device.

[0157] In this application, reference is made to Figure 15-16 The steam oven may include a first heating element 84. The first heating element 84 may be used to heat the air in the cooking cavity. The first heating element 84 may be at least partially disposed in the cooking cavity. The provision of the first heating element enables the steam oven to achieve a baking function.

[0158] In this application, reference is made to Figure 15-16 The steam oven may include a second heating element 85. The second heating element may be arranged in the blower cavity. The second heating element can heat the air in the blower cavity.

[0159] The second heating element may include a first heating section 851. The first heating section may surround the outside of the fan along the circumference of the fan. The first heating section may be spirally wound into at least two turns.

[0160] The second heating element 85 can heat the air after it flows out from the centrifugal fan, and the heated air flows back to the cooking cavity through the air outlet.
