[0025] The present application provides a steam oven, Figure 1 is a schematic structural diagram of an embodiment of the steam oven provided by the present application.

[0026] In combination Figure 1 , the steam oven provided by the present application has the functions of steaming and baking, and is provided with a steam baking cavity in which food can be placed for steaming or baking treatment.

[0027] Specifically, the steam oven is provided with a pressure relief gas outlet of the steam baking cavity, the pressure relief gas outlet of the steam baking cavity communicates the steam baking cavity with the outside, and the gas in the steam baking cavity can be discharged to the outside through the pressure relief gas outlet. When the steam oven is working, steam will be formed in the steam baking cavity, at this time part of the steam will be discharged through the pressure relief gas outlet, thereby ensuring that the air pressure in the steam baking cavity will not be too high to cause danger.

[0028] The steam oven further comprises a heat dissipation device, the heat dissipation device is arranged at the pressure relief gas outlet, and the heat dissipation device is used for dissipating heat to the outside of the steam oven and taking away the gas at the pressure relief gas outlet. The outside of the steam oven can be the outer wall of the steam baking cavity. The heat dissipation device is part of the steam oven, and the heat dissipation device can be fixedly arranged relative to the outer wall of the steam baking cavity.

[0029] It should be understood that when the steam oven is working, the outer wall of the steam baking cavity will have a relatively high temperature, and the heat dissipation device is needed to dissipate heat to the outer wall of the steam baking cavity. On the other hand, the steam in the steam baking cavity will be discharged from the pressure relief gas outlet and then taken away by the heat dissipation fan.

[0030] Further in combination with the above and Figure 1 , when the steam oven is working, the steam in the steam baking cavity is guided out through the pressure relief gas outlet H to form a steam gas flow A1, and the heat dissipation device forms a heat dissipation gas flow A2 in the process of taking away the heat of the outer wall of the steam baking cavity, and the steam gas flow A1 and the heat dissipation gas flow A2 can be discharged by the heat dissipation device in the form of a mixed gas flow A3. At this time, the heat dissipation fan not only realizes the discharge of the steam, but also realizes the heat dissipation to the outer wall of the steam baking cavity.

[0031] Further, the heat dissipation device can generate heat dissipation airflows with different wind speeds, and the heat dissipation airflows with different wind speeds can have different heat dissipation effects on the outer wall and different steam discharge effects on the steam airflow.

[0032] When the steam oven is working, the outer wall of the steam oven cavity can have different temperatures in different working states or working stages, and the pressure relief air outlet can also have different steam airflows. In this case, the heat dissipation device with different wind speeds can selectively adapt to different situations to achieve better heat dissipation effects.

[0033] In some specific embodiments, the heat dissipation device can be a heat dissipation fan, which can adjust multiple wind speeds to meet the heat dissipation requirements in different situations.

[0034] The application also provides a heat dissipation method of a steam oven. Figure 2 is a flowchart of an embodiment of the heat dissipation method of the steam oven provided by the application, as Figure 2 shown, the method comprises the following steps:

[0035] S11: Obtain a current temperature parameter in the steam oven cavity.

[0036] Specifically, when the steam oven is working, the temperature parameter in the steam oven cavity can change with the change of time. Especially in the heating or cooling state, the temperature parameter in the steam oven can be in a state of constant change.

[0037] The current temperature parameter is the temperature parameter at the current time, and this step can obtain the temperature parameter in the steam oven cavity in real time by obtaining the current temperature parameter of the steam oven cavity.

[0038] The current temperature parameter can be a current temperature size parameter, and the current temperature size can be the size of the current average temperature in the steam oven cavity. In subsequent embodiments, unless otherwise specified, the current temperature parameter is the current temperature size parameter.

[0039] In some specific embodiments, the current temperature parameter can be obtained by a temperature sensor arranged in the steam oven cavity. The number of temperature sensors can be multiple, and the average value of the current temperature parameters obtained by the multiple sensors can be the final current temperature parameter.

[0040] S12: Adjust the wind speed of the heat dissipation device to a preset wind speed range according to the current temperature parameter.

[0041] After the current temperature parameter is acquired, the wind speed of the heat dissipation device is adjusted to be within the preset wind speed range according to a preset relationship between the current temperature parameter and the preset wind speed range.

[0042] Specifically, the preset relationship between the temperature parameter and the preset wind speed range can be preset and stored, which can be set by the system or directly by the user. Moreover, the preset relationship can be modified by the system and the user, so that the modified preset relationship between the temperature parameter and the preset wind speed range can meet the current needs of the steam oven and the user.

[0043] More specifically, the preset relationship at least satisfies that when the wind speed of the heat dissipation device is within the preset wind speed range, the wind speed of the heat dissipation device matches the heat dissipation demand of the outer wall of the steam oven. At this time, unnecessary heat dissipation or energy loss in the steam oven will not occur due to the excessive wind speed of the heat dissipation device. On the other hand, the outer wall of the steam oven cannot be well cooled due to the insufficient wind speed.

[0044] The temperature parameter and the preset wind speed range can be one-to-one corresponding, so as to ensure that after the current temperature parameter is acquired, the wind speed of the heat dissipation device can be determined to be within the unique preset wind speed range.

[0045] For the step of adjusting the wind speed of the heat dissipation device to be within the preset wind speed range, in some embodiments, the wind speed can be adjusted to any wind speed within the preset wind speed range. In other embodiments, the wind speed can be adjusted to the average wind speed within the preset wind speed range.

[0046] In combination with the above, in some specific application scenarios, after the current temperature parameter is acquired, it is first determined whether the current temperature parameter corresponds to the preset wind speed range, and when it is determined that the current temperature parameter corresponds to the preset wind speed range, the wind speed of the heat dissipation device is adjusted so that the wind speed is within the preset wind speed range.

[0047] In summary, the current temperature parameter in the steam oven is acquired, and then the wind speed of the heat dissipation fan is adjusted according to the current temperature parameter, so that the wind speed of the heat dissipation fan is within the preset wind speed range. Therefore, the wind speed of the heat dissipation fan can be adjusted according to the real-time temperature parameter in the steam oven, so that the wind speed of the heat dissipation fan is within the preset wind speed range, the wind speed of the heat dissipation fan matches the heat dissipation demand, and unnecessary heat dissipation and energy loss are reduced.

[0048] In some specific embodiments, the current temperature parameter corresponds to the preset wind speed range one-to-one in the mutually non-overlapping temperature parameter range and the mutually non-overlapping preset wind speed range, and the average of the temperature parameter range and the average of the preset wind speed range are positively correlated.

[0049] The temperature parameter can be divided into a plurality of temperature parameter ranges according to the temperature size, and the plurality of temperature parameter ranges do not have the same part to achieve non-overlapping. The preset wind speed range can be divided into a plurality of preset wind speed ranges according to the wind speed size, and the plurality of preset wind speed ranges do not have the same part to achieve non-overlapping.

[0050] By dividing the temperature parameter into a temperature parameter range, and then adjusting the temperature parameter range and the preset temperature range, the wind speed can be adjusted through the temperature range in the application scenario where the temperature changes rapidly.

[0051] When the mean value of the temperature parameter range and the mean value of the preset wind speed range are positively correlated, the greater the mean value of the temperature parameter range, the greater the mean value of the corresponding preset wind speed range. At this time, when the mean value of the temperature parameter range is small, the mean value of the corresponding preset wind speed range can be set to be small, and when the mean value of the temperature parameter range is large, the mean value of the corresponding preset wind speed range can be set to be large.

[0052] It should be understood that when the temperature parameter range is large, the temperature of the outer wall of the steaming and baking cavity is also high, and at this time the heat dissipation demand is also large, so the mean value of the corresponding preset wind speed range is set to be large.

[0053] Please refer to Figure 3 , Figure 3 is a flowchart of another embodiment of the heat dissipation method of the steaming and baking oven provided in the present application. The present embodiment can be based on the above-mentioned embodiment that the temperature parameter range and the preset wind speed range correspond one by one, specifically, the above-mentioned step S12 comprises:

[0054] S121: Obtain the change state of the temperature parameter in the steaming and baking cavity.

[0055] The change state of the temperature parameter can be the change state of the temperature size in a preset time period, which can be a time period from a certain time in the past to the current time.

[0056] Specifically, the change state of the temperature parameter is the change state of the temperature size, which can be obtained by obtaining the temperature size value in the preset time period, and then obtaining the change state of the temperature size according to the temperature size value in the preset time period.

[0057] When the temperature size value is increasing, the change state of the temperature parameter is an increasing state. When the temperature size value is decreasing, the change state of the temperature parameter is a decreasing state.

[0058] S122: When the change state of the temperature parameter is an increasing state, adjust the heat dissipation device so that the wind speed of the heat dissipation device increases.

[0059] When the change state of the temperature parameter is in the increasing state, it indicates that the temperature in the steam roasting cavity is in the increasing state. At this time, in order to achieve sufficient heat dissipation of the outer wall of the steam roasting cavity, the air speed of the heat dissipation device should be increased.

[0060] In combination with the above-mentioned contents in the embodiments, even when the air speed of the heat dissipation device is in the increasing state, the air speed of the heat dissipation device is always within the preset temperature parameter range corresponding to the current temperature parameter.

[0061] For example, a certain temperature parameter range is 50-100℃, and the preset air speed range corresponding to the temperature parameter range is 5-10 gears, and the larger the gear number is, the larger the air speed is. When the change state of the temperature parameter in the temperature parameter range is in the increasing state, the current temperature parameter is 60℃, the air speed corresponds to 6 gears, the current temperature parameter changes to 70℃, the air speed corresponds to 7 gears, and so on. However, even if the air speed corresponding to the current temperature parameter increases, as long as the current temperature parameter is within 50-100℃, the air speed will not exceed the preset air speed range of 5-10 gears, that is, will not exceed 10 gears.

[0062] It should be understood that when the change state of the temperature parameter is in the increasing state, the steam roasting cavity is in the heating state. At this time, if the air speed is too large, unnecessary heat loss will be caused, which will lead to slow temperature rise in the steam roasting cavity, which is not conducive to the temperature rise in the steam roasting cavity.

[0063] By increasing the air speed of the heat dissipation device when the change state of the temperature parameter is in the increasing state, the air speed can be small when the temperature is low, which can avoid unnecessary heat loss caused by large air speed and affect the rapid temperature rise. Moreover, no matter how the air speed changes, it is always within the preset range, so that the basic heat dissipation demand can be met.

[0064] Please refer to Figure 4 , Figure 4 is a flowchart of another embodiment of the heat dissipation method of the steam roasting oven provided in the present application.

[0065] S121: Obtain the change state of the temperature parameter in the steam roasting cavity.

[0066] This step refers to the contents in the above-mentioned embodiments, which will not be repeated.

[0067] S123: When the change state of the temperature parameter is in the decreasing state, adjust the heat dissipation device so that the air speed of the heat dissipation device decreases.

[0068] The related contents of this step can refer to the above-mentioned embodiments in which the change state of the temperature parameter is in the increasing state, and this step and step S122 have no sequence relationship in implementation.

[0069] It should be understood that when the change state of the temperature parameter is in a decreasing state, the steam roasting cavity is in a cooling state. When the change state of the temperature parameter is in a decreasing state, the heat dissipation device is adjusted so that the air speed of the heat dissipation device decreases, so that the heat dissipation is performed at a smaller temperature and at a smaller air speed. Since the air speed at this time is still within the preset air speed range, better heat dissipation effect can be achieved, and unnecessary energy loss caused by heat dissipation at a large air speed at a small temperature can be avoided.

[0070] In combination with the above, in some specific embodiments, each preset air speed range is divided into a first sub-pre-set air speed range and a second sub-pre-set air speed range, and the average air speed in the first sub-pre-set air speed range is greater than the average air speed in the second sub-pre-set air speed range.

[0071] More specifically, the first sub-pre-set air speed range and the second sub-pre-set air speed range do not overlap each other, and the range width of the first sub-pre-set air speed range can be the same as the range width of the second sub-pre-set air speed range.

[0072] For example, a preset air speed range is divided into 1-4 gears, and the larger the gear number, the larger the corresponding air speed. The first sub-pre-set air speed range can be 3-4 gears, and the second sub-pre-set air speed range can be 1-2 gears.

[0073] Wherein, when the temperature parameter is in the same temperature parameter range, the temperature parameter in the decreasing state corresponds to the first sub-pre-set air speed range, and the temperature parameter in the increasing state corresponds to the second sub-pre-set air speed range.

[0074] In combination with the above example, the preset air speed range is divided into 1-4 gears, the first sub-pre-set air speed range is 3-4 gears, the second sub-pre-set air speed range is 1-2 gears, and the temperature parameter range corresponding to the preset air speed range is 100-200°C. Then, when the temperature parameter decreases in the range of 100-200°C, the current temperature parameter corresponds to the first sub-pre-set air speed range 3-4 gears. When the temperature parameter increases in the range of 100-200°C, the current temperature parameter corresponds to the second sub-pre-set air speed range 1-2 gears.

[0075] It should be understood that although the same preset air speed range corresponds to the same temperature parameter range, in the same temperature parameter range, if the temperature parameter is in a decreasing state, a larger air speed is required to achieve faster cooling. If the temperature parameter is in an increasing state, a smaller air speed is required to avoid the influence of a large air speed on rapid heating.

[0076] Therefore, through the above embodiments, the temperature state change corresponds to different sub-wind speed ranges in the same temperature range, and the temperature is prevented from being affected by rapid heating during the heating process in the temperature range, and the temperature is rapidly reduced during the cooling process in the temperature range.

[0077] Figure 5 is a flowchart of another embodiment of the heat dissipation method of the steam oven provided in the present application, as Figure 5 The method further includes the following steps:

[0078] S21: Obtain a current humidity parameter in the steam oven.

[0079] The current humidity parameter is the humidity parameter at the current time, so that the humidity parameter in the steam oven can be obtained in real time.

[0080] Specifically, the current humidity parameter can be obtained by a humidity sensor arranged in the steam oven. The current humidity parameter can be a size parameter of the current humidity. In subsequent embodiments, unless otherwise specified, the current humidity parameter can be a size parameter of the current humidity.

[0081] S22: When the current temperature parameter corresponds to a preset wind speed range, and the average wind speed of the preset wind speed range corresponding to the current humidity parameter is greater than the average wind speed of the preset wind speed range corresponding to the current temperature range, adjust the wind speed of the heat dissipation device to be within the preset wind speed range according to the current humidity parameter; wherein the humidity parameter and the preset wind speed range have a corresponding relationship.

[0082] The corresponding relationship between the current humidity parameter and the preset wind speed range is pre-set and stored, which can be pre-set by the system or the user and can be changed by the system or the user.

[0083] When the current temperature parameter corresponds to a preset wind speed range, it means that the wind speed does not need to be adjusted at this time. At this time, the wind speed of the heat dissipation device is further adjusted according to the current humidity parameter. If the average wind speed of the preset wind speed range corresponding to the current humidity parameter is greater than the average wind speed of the preset wind speed range corresponding to the current temperature range, it means that a greater wind speed is needed under the current humidity parameter. Then, the wind speed is adjusted to be within the preset wind speed range according to the current humidity parameter at this time, that is, to the preset wind speed range with a greater average wind speed.

[0084] In some specific embodiments, the preset wind speed range corresponding to the current humidity parameter and the preset wind speed range corresponding to the current temperature range with a smaller average wind speed do not overlap.

[0085] It should be understood that when the humidity in the steam oven is large, more steam flow will be gathered at the pressure relief outlet, and at this time, the heat dissipation device needs a larger air speed to guide the steam flow away to avoid condensation of steam, resulting in water accumulation and rust. At this time, although the corresponding air speed of the heat dissipation device can perform good heat dissipation on the outer wall of the steam oven, in order to better guide the steam flow away, the air speed in the wind speed range corresponding to the average wind speed of the current humidity parameter is used for heat dissipation.

[0086] Based on the above implementation of adjusting the air speed according to the current humidity parameter, in the implementation of obtaining both the current temperature parameter and the current humidity parameter, the method further comprises: when the average value of the preset wind speed range corresponding to the current humidity parameter is less than the average value of the preset wind speed range corresponding to the current temperature parameter, adjusting the air speed of the heat dissipation device to the preset wind speed range according to the current temperature parameter.

[0087] It should be understood that when the heat dissipation device works at a larger air speed exceeding the preset wind speed range corresponding to the current temperature parameter, if the humidity parameter in the steam oven becomes smaller, the preset wind speed range corresponding to the current temperature parameter will also become smaller. When the average value of the preset wind speed range corresponding to the current humidity parameter is less than the average value corresponding to the current temperature parameter, it means that for the humidity factor, heat dissipation by the smaller air speed corresponding to the current humidity parameter is sufficient, but in order to ensure good heat dissipation effect on the outer wall of the steam oven, the air speed of the heat dissipation device needs to be adjusted according to the current temperature parameter.

[0088] In summary, in some specific embodiments, the current humidity parameter corresponds to a non-overlapping humidity parameter range and a non-overlapping preset wind speed range, and the average value of the humidity parameter range and the average value of the preset wind speed range are positively correlated.

[0089] In combination with the temperature parameter range, the humidity parameter range and the preset wind speed parameter range, in some specific embodiments, the temperature parameter range can be divided into a first temperature parameter range and a second temperature parameter range, the humidity parameter range can be divided into a first humidity parameter range and a second humidity parameter range, and the preset wind speed range can be divided into a first preset wind speed range and a second preset wind speed range.

[0090] In this implementation, the temperature parameter range, the humidity parameter range and the preset wind speed parameter range are all divided into two ranges. At this time, the two divided ranges are non-overlapping.

[0091] The first temperature parameter range and the first humidity parameter range correspond to the first preset wind speed range, and the second temperature parameter range and the second humidity parameter range correspond to the second preset wind speed range.

[0092] Specifically, the temperature in the first temperature parameter range is greater than the temperature in the second temperature parameter range, the humidity in the first humidity parameter range is greater than the humidity in the second humidity parameter range, and the wind speed in the first preset wind speed range is greater than the wind speed in the second preset wind speed range.

[0093] In combination with the above embodiments, the wind speed in the first wind speed range and the second preset wind speed range can be set according to the following embodiments.

[0094] The maximum wind speed in the first preset wind speed range is a first maximum wind speed, and the maximum wind speed in the second preset wind speed range is a second maximum wind speed. The first maximum wind speed is less than or equal to 3 times the second maximum wind speed, and the first maximum wind speed is greater than or equal to 1.1 times the second maximum wind speed.

[0095] Through the above setting mode, the demand for wind speed in different preset wind speed ranges can be met in different temperature ranges or different humidity ranges.

[0096] Please refer to Figure 6 , Figure 6 is a structural frame diagram of another embodiment of the steam oven provided by the present application.

[0097] In combination with the above content, the steam oven further comprises a temperature and humidity sensor and a processor.
