Detailed Implementation

[0034] With the iterative upgrades in cooking technology, gas-fired steam ovens, as a new type of kitchen equipment, are gradually becoming a technological replacement for traditional electric steam ovens. Gas-fired steam ovens are widely used in catering, food processing, and other fields. In steam-bake mode, the gas is burned to produce high-temperature flue gas, which enters the atomization chamber, mixing chamber, and then the cooking chamber through the flue. However, in related technologies, the cross-sectional area of ​​the flue is fixed, resulting in airflow resistance and making it easy for water vapor in the atomization chamber to flow back. At the same time, the atomization chamber and mixing chamber have simple structural designs, often resulting in insufficient mixing of the high-temperature flue gas and the spray, affecting the uniformity of steaming and baking.

[0035] Based on the above problems, this utility model proposes a heating device to solve the demand for high-temperature flue gas flow rate under different working conditions, while improving the mixing of high-temperature flue gas and spray, shortening the evaporation time, and improving the uniformity of steaming and baking.

[0036] Therefore, this utility model provides a heating device and cooking equipment to solve the problem that high-temperature flue gas and spray cannot be effectively mixed.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figures 1 to 4 The heating device 10 according to an embodiment of the present invention includes: a heating component 11, a humidifying component 12 and a mixing component 13.

[0039] The heating component 11 is configured to generate hot airflow, which heats the airflow to form hot airflow. The humidifying component 12 is connected to the heating component 11 and is used to humidify the hot airflow. The mixing component 13 is connected to the humidifying component 12, and the hot airflow is output from the exhaust port after passing through the humidifying component 12 and the mixing component 13. The hot airflow generated by the heating component 11 passes through the humidifying component 12 and then enters the mixing component 13. When the hot airflow passes through the humidifying component 12, the humidifying component 12 can be turned on, mixing water mist or water vapor into the hot airflow flowing through it. Subsequently, the hot airflow will enter the mixing component 13, where it will fully mix and exchange heat with the fluid provided in the humidifying component 12, thus regulating the humidity of the hot airflow. Simultaneously, the fluid input into the humidifying component 12 and the hot airflow can undergo sufficient heat exchange within the mixing component 13, preventing or reducing water mist or condensation carried in the hot airflow output from the exhaust port. This increases the humidity of the hot airflow while preventing water mist or condensation from affecting the taste of the cooked food.

[0040] Specifically, when humidification of the hot airflow is not required, the humidification component 12 can be turned off. After the heating component 11 generates hot airflow, the hot airflow is controlled to flow into the cooking chamber 201, thereby cooking the food in the cooking chamber 201. When humidification of the hot airflow is required, the humidification component 12 and the heating component 11 can be turned on. The heating component 11 heats and generates hot airflow, which then passes through the humidification component 12 and enters the mixing component 13. When the airflow passes through the humidification component 12, the humidity of the hot airflow changes. After entering the mixing component 13, the humid airflow and the hot airflow will further exchange heat, thereby heating the water mist and other moisture generated by the humidification component 12 into water vapor. The humidified hot airflow can be used to cook the food in the cooking chamber 201, and the water mist entering the cooking chamber 201 can be avoided or reduced, improving the uniformity of heating.

[0041] For example, the heating component 11 can generate a hot airflow. Before the hot airflow enters the cooking cavity 201, the humidifying component 12 can humidify the hot airflow and adjust its humidity to increase the cooking temperature inside the cooking cavity 201, thereby heating the food inside the cooking cavity 201. The hot airflow can also be blown directly onto the surface of the food to heat it. The humidifying component 12 can generate a humid airflow, which may include water mist, water vapor, or condensation.

[0042] The humidified hot airflow can maintain a certain level of humidity within the cooking cavity 201, reducing moisture loss from the food and preserving its color and flavor. Simultaneously, by adjusting the humidity before the hot airflow enters the cooking cavity 201 using the humidification component 12, the humidity within the cooking cavity 201 can be adjusted to the user-set target humidity, thereby enhancing the user experience. Users can adjust the humidity within the cooking cavity 201 according to their needs, making the cooking equipment 100 suitable for diverse usage scenarios.

[0043] The heating device 10 according to an embodiment of the present invention uses a mixing component 13 to receive hot and humid airflows, allowing the hot and humid airflows to contact and exchange heat, and quickly generating a high-temperature mixed airflow, thereby improving the heating efficiency of the heating device 10. The heating device 10 of the present invention can provide a mixing component 13 with uniform mixing and unidirectional airflow, enabling thorough mixing of humid airflow (e.g., ultrasonically atomized droplets) directly with hot airflow (e.g., high-temperature flue gas). The humidity of the hot airflow can be adjusted to reduce moisture loss from food and improve the texture of the food.

[0044] like Figures 1 to 8 In some embodiments, the heating device 10 includes a flue 141 connecting the heating assembly 11 and the humidification assembly 12. The flue 141 is configured to allow airflow from the heating assembly 11 to the humidification assembly 12 and restrict airflow from the humidification assembly 12 back to the heating assembly 11. The flue 141 can guide the hot airflow generated by the heating assembly 11 to the humidification assembly 12 and the mixing assembly 13, and can also prevent the humidified airflow in the humidification assembly 12 from flowing back into the heating assembly 11. Especially when the heating assembly 11 is heated by the burner 112, restricting the humidified airflow back to the heating assembly 11 can avoid the influence of humidified airflow on the burner 112, thereby improving the stability and service life of the burner 112. Based on the unidirectional flow principle, an integrated module of unidirectional flow guidance and enhanced heat transfer is formed.

[0045] In some embodiments, the flue 141 includes at least one flow path (e.g., at least one of the first flow path 1411, the second flow path 1412, and the third flow path 1413 described below), which can be configured as a Tesla valve structure. A Tesla valve structure refers to a structure similar to the internal flow channel of a Tesla valve, which restricts fluid flow preferentially in one direction without the need for moving parts (see US Patent 1329559A). The multi-stage Tesla valve channel design in the flue 141 accelerates the flow of high-temperature flue gas and improves the heat exchange efficiency with atomized droplets during forward flow, while increasing resistance to effectively prevent backflow during reverse flow. Of course, the flue 141 in this invention can also be configured with other forms of flow paths, such as one-way valves, electrically controlled valves, etc. The Tesla valve structure used in this invention simplifies the check valve structure and optimizes the check valve effect. The Tesla valve design in the flue 141 increases the flue gas flow rate while effectively reducing water vapor backflow.

[0046] like Figure 4 , Figure 5 and Figure 7 The flue 141 includes multiple flow paths connected in parallel. A multi-stage Tesla valve-type channel prevents reverse airflow. By setting up multiple flow paths, a large flow rate can be achieved. The advantage of this design is that during forward flow, the fluid achieves low resistance through the inertial effect of the meandering path and pressure difference, and the flow can be accelerated through structural design; when flowing in reverse, the increased path complexity leads to significant energy dissipation, creating high flow resistance and effectively preventing backflow.

[0047] The heating device 10 also includes a flow control component configured to adjust the flow area of ​​the flue 141. The flow rate of the flue 141 can be controlled, thereby controlling the flow rate of the hot gas flow, so as to control the fluid temperature, humidity, etc., output from the heating device 10.

[0048] The flow control component can be configured to include at least one baffle at the inlet of the flue 141. The at least one baffle is used to adjust the opening of the flue 141. Adjusting the opening of the flue 141 by the baffle can simplify the structure of the flow control component and facilitate the control of the flow control component, simplify the structure of the heating device 10, improve the control efficiency, and facilitate the quick switching of the heating mode of the heating component 11.

[0049] The way in which the flue 141 is combined with the flow control component may include, but is not limited to, the following implementation methods.

[0050] In one embodiment, the flue 141 includes a first flow path 1411, the inlet of which is connected to the heating assembly 11 and the outlet of which is connected to the humidification assembly 12. At least one baffle includes a first baffle 1421, which is located at the inlet of the first flow path 1411 and is used to open and close the first flow path 1411. The baffle can be used to control the flow path's on / off state, simplifying operation and improving the stability and efficiency of flow control in the flue 141.

[0051] In the second embodiment, the flue 141 includes a first flow path 1411, the inlet of the first flow path 1411 is connected to the heating component 11 and the outlet is connected to the humidification component 12, and at least one baffle includes a first baffle 1421, which is disposed at the inlet of the first flow path 1411 and is used to open and close the first flow path 1411.

[0052] The flue 141 also includes a second flow path 1412 connected in parallel with the first flow path 1411. The inlet of the second flow path 1412 is connected to the heating assembly 11 and the outlet is connected to the humidification assembly 12. At least one baffle includes a second baffle 1422, which is disposed at the inlet of the second flow path 1412 and is used to open and close the second flow path 1412. The first baffle 1421 and the second baffle 1422 can be used to control the complete opening and complete isolation of the flue 141, facilitating the control of the flue 141.

[0053] In the third embodiment, the flue 141 includes a first flow path 1411, the inlet of the first flow path 1411 is connected to the heating component 11 and the outlet is connected to the humidification component 12, and at least one baffle includes a first baffle 1421, which is disposed at the inlet of the first flow path 1411 and is used to open and close the first flow path 1411.

[0054] The flue 141 also includes a third flow path 1413 connected in parallel with the first flow path 1411. The inlet of the third flow path 1413 is connected to the heating component 11, and the outlet is connected to the humidification component 12. The flow rate of the flue 141 can be adjusted using the first baffle 1421. Since the third flow path 1413 is not equipped with a baffle, the flue 141 always has a certain flow rate, which facilitates the rapid switching of the flue 141 between different modes and reduces costs.

[0055] Implementation method four, such as Figure 4 The flue 141 includes a first flow path 1411, the inlet of which is connected to the heating component 11 and the outlet of which is connected to the humidification component 12. At least one baffle includes a first baffle 1421, which is disposed at the inlet of the first flow path 1411 and is used to open and close the first flow path 1411.

[0056] The flue 141 also includes a second flow path 1412 connected in parallel with the first flow path 1411. The inlet of the second flow path 1412 is connected to the heating component 11 and the outlet is connected to the humidification component 12. At least one baffle includes a second baffle 1422, which is located at the inlet of the second flow path 1412 and is used to open and close the second flow path 1412.

[0057] The flue 141 also includes a third flow path 1413 connected in parallel with the first flow path 1411. The inlet of the third flow path 1413 is connected to the heating component 11 and the outlet is connected to the humidification component 12. The third flow path 1413 can be located between the first flow path 1411 and the second flow path 1412.

[0058] Of course, the above description is only some embodiments of this utility model and is not a limitation on the protection valve of this utility model. The number of flow paths and the corresponding number of baffles included in the flue 141 in this utility model can also be other embodiments, and the number of flow paths and the number of baffles can be the same or different.

[0059] The flue 141 employs a Tesla valve design with multiple flow paths and an adjustable baffle. This allows for dynamic adjustment of the flue 141's cross-sectional area based on operating conditions, thereby achieving different high-temperature flue gas velocities to adapt to various cooking modes (steaming / baking / wet baking). The baffle enables the flue 141 to vary its cross-section, accommodating different conditions such as steaming, baking, and wet baking, thus improving overall cooking efficiency.

[0060] The baffles (such as the aforementioned first baffle 1421, second baffle 1422 and / or third baffle) can be configured as high-temperature resistant plates, thereby improving the performance and service life of the baffles, while also improving the safety of the output fluid of the heating device 10 and optimizing food safety.

[0061] To achieve high-temperature resistance of the baffle, the following embodiments are possible, including but not limited to: the baffle is configured as a high-temperature resistant alloy plate; or, the material of the baffle includes austenitic chromium-nickel stainless steel plate or Cornell alloy plate; or, the surface of the baffle is provided with a high-temperature resistant coating; or, the surface of the baffle is provided with an alumina coating or a silicon carbide coating. Of course, the baffle in this invention can also be in other forms. For example, the baffle can be a combination of the baffles described in the foregoing examples. For instance, the baffle can be set as a high-temperature resistant alloy plate, and an alumina coating can be provided on the surface of the baffle.

[0062] In addition, to improve the sealing effect between the baffle and the corresponding flow path, a sealing structure can be set on the baffle.

[0063] The sealing structure on the baffle can include, but is not limited to, the following embodiments: a sealing layer is provided on the surface of the baffle opposite to the flue 141; or, a graphite-based composite material layer is provided on the surface of the baffle opposite to the flue 141; or, a flexible graphite layer or an expanded graphite layer is provided on the surface of the baffle opposite to the flue 141. This can improve the sealing effect of the baffle on the flow path, thereby facilitating effective regulation of the flow rate of the flue 141.

[0064] The flow control component also includes a stepper motor, which is connected to a baffle and drives the baffle to rotate, opening and closing the corresponding flow path. Using the stepper motor, the opening and closing of the corresponding flow path can be quickly controlled, improving the stability and efficiency of the flow control component. This allows for rapid adjustment of the flow rate in the flue 141.

[0065] In some embodiments, the heating device 10 includes a single-steam mode, in which the flow control component controls the flow rate of the flue 141 to a first flow rate, wherein the first flow rate can be the maximum flow rate of the flue 141; the heating device 10 may also include a single-bake mode, in which the flow control component controls the flow rate of the flue 141 to a second flow rate, wherein the second flow rate can be the minimum flow rate of the flue 141 (greater than zero); the heating device 10 may also include a wet-bake mode, in which the flow control component adjusts the flow rate of the flue 141 between the first flow rate and the second flow rate.

[0066] Furthermore, the aforementioned first flow rate is greater than the second flow rate. For example, in the fourth embodiment of the cooperation between the flue 141 and the flow control component, in the single steaming mode, the first baffle 1421 and the second baffle 1422 can be set to open, at which time the first flow path 1411, the second flow path 1412 and the third flow path 1413 are all open, and the flue 141 has the maximum flow rate; in the single baking mode, the first baffle 1421 and the second baffle 1422 can be set to close, at which time the first flow path 1411 and the second flow path 1412 are closed, and the third flow path 1413 is open, and the flue 141 has the minimum flow rate.

[0067] In conjunction with the foregoing description, the cooking mode of the heating device 10 may also have the following characteristics.

[0068] In the wet-bake mode, the heating element 11 operates and adjusts the humidification element 12 according to the baking information to control the humidity inside the cooking cavity 201, thus achieving adjustable humidity within the cooking cavity 201. Users can set the desired baking information before operating the cooking device 100. In wet-bake mode, the heating element 11 generates hot airflow, and the humidification element 12 adjusts the humidity of the hot airflow according to the baking information. The humidified hot airflow can then be introduced into the cooking cavity 201 to control the humidity within the cooking cavity 201 to the user's desired target humidity, improving the user experience. Furthermore, compared to hot airflow directly entering the cooking cavity 201, the presence of humidified hot airflow entering the cooking cavity 201 and heating the food reduces moisture loss from the food within the cooking cavity 201, preserving the color and flavor of the food and preventing over-drying.

[0069] In the wet-bake mode, the humidification component 12 can be adjusted to control the humidity inside the cooking cavity 201 to be less than or equal to 40%. The heating component 11 can generate hot airflow, and the humidification component 12 can adjust the humidity of the hot airflow to make it less humid. The less humid hot airflow can enter the cooking cavity 201 to control the humidity inside the cooking cavity 201 to be less than or equal to 40%. The hot airflow can blow onto the surface of the food to heat the food inside the cooking cavity 201. The air inside the cooking cavity 201 can absorb the heat from the humid airflow, raising the air temperature and baking the food. The cooking cavity 201 still has a certain humidity, which can prevent over-baking of the food and reduce the loss of moisture from the food.

[0070] In the single-steam mode, the heating component 11 and the humidifying component 12 operate. In conjunction with the foregoing, compared to the wet-bake mode, the humidity of the cooking cavity 201 in the single-steam mode is higher than that in the wet-bake mode. The heating component 11 generates a hot airflow, and the humidifying component 12 adjusts the humidity of the hot airflow to ensure it has a higher humidity level. This higher humidity hot airflow enters the cooking cavity 201, increasing the humidity within the cavity. The higher humidity hot airflow can then be directed towards the surface of the food to heat it and keep its surface moist. The air within the cooking cavity 201 absorbs the heat from the humid airflow, raising its temperature. Simultaneously, the higher humidity within the cooking cavity 201 allows for the steaming and cooking of the food within the cavity.

[0071] In single-steam mode, the humidification component 12 can operate at maximum power, improving its humidification efficiency. The heating component 11 generates a hot airflow, the humidity of which is adjusted by the humidification component 12 to achieve a high humidity level. This high-humidity hot airflow can quickly enter the cooking chamber 201, rapidly increasing the humidity within it and further enhancing the humidification efficiency of the humidification component 12. The high-humidity hot airflow can also be directed towards the surface of the food, heating it and keeping it moist. The air within the cooking chamber 201 absorbs the heat from the humid airflow, raising its temperature. Simultaneously, the high humidity within the cooking chamber 201 facilitates the steaming and cooking of the food.

[0072] Optionally, in single steam mode, the humidification component 12 is adjusted to control the humidity inside the cooking cavity 201 to be greater than or equal to 80%. The heating component 11 can generate hot airflow, and the humidification component 12 can adjust the humidity of the hot airflow to make it more humid. The humid hot airflow can be introduced into the cooking cavity 201 to control the humidity inside the cooking cavity 201 to be greater than or equal to 80%. The air inside the cooking cavity 201 can absorb the heat of the humid airflow, causing the air temperature to rise. The hot airflow can be blown onto the surface of the food to steam the food inside the cooking cavity 201 and keep the surface of the food moist.

[0073] In single-bake mode, hot air can be directly introduced into the cooking cavity 201 to heat the food, and the humidification component 12 does not need to be activated at this time.

[0074] like Figure 2 and Figure 3 In some embodiments, the heating device 10 further includes a connecting channel 143, which is disposed between the humidifying component 12 and the mixing component 13. At least a portion of the connecting channel 143 has a gradually changing cross-sectional area in the direction from the humidifying component 12 to the mixing component 13, which can form a turbulence structure, improve the mixing uniformity of hot air and humid air, increase the heat exchange efficiency of hot air and humid air, avoid excessive water mist, condensate, etc. in the airflow output from the exhaust port 133, and improve the taste of food cooking.

[0075] The structure in which at least a portion of the connecting channel 143 has a gradually changing cross-sectional area from the humidifying component 12 to the mixing component 13 may include, but is not limited to, the following embodiments.

[0076] In one embodiment, at least a portion of the connecting channel 143 may be configured such that the cross-sectional area of ​​the channel gradually decreases in the direction from the humidifying component 12 to the mixing component 13. That is, at least a portion of the connecting channel 143 tapers in the direction from the humidifying component 12 to the mixing component 13. For example, at least a portion of the connecting channel 143 may have opposing side walls, wherein at least one side wall gradually approaches the other side wall to construct a structure in which the cross-sectional area of ​​the channel gradually decreases; or, at least a portion of the connecting channel 143 may be configured as a circular channel with a gradually decreasing radial dimension to construct a structure in which the cross-sectional area of ​​the channel gradually decreases, etc.

[0077] In the second embodiment, at least a portion of the connecting channel 143 may be configured such that the cross-sectional area of ​​the channel gradually increases in the direction from the humidifying component 12 to the mixing component 13. That is, at least a portion of the connecting channel 143 gradually expands in the direction from the humidifying component 12 to the mixing component 13. For example, at least a portion of the connecting channel 143 may have opposing side walls, wherein at least one side wall gradually moves away from the other side wall to construct a structure in which the cross-sectional area of ​​the channel gradually increases; or, at least a portion of the connecting channel 143 may be configured as a circular channel with a gradually increasing radial dimension to construct a structure in which the cross-sectional area of ​​the channel gradually increases, etc.

[0078] In the third embodiment, at least a portion of the connecting channel 143 can be configured such that the cross-sectional area of ​​the flow channel gradually decreases and then gradually increases in the direction from the humidifying component 12 to the mixing component 13. That is, at least a portion of the connecting channel 143 adopts a tapered-widening structure in the direction from the humidifying component 12 to the mixing component 13. For example, at least a portion of the connecting channel 143 can have opposing side walls, wherein at least one side wall gradually approaches the other side wall and then gradually moves away from the other side wall, thus constructing a structure where the cross-sectional area of ​​the flow channel gradually decreases and then gradually increases; or, at least a portion of the connecting channel 143 can be configured as a circular flow channel with a radial dimension that gradually decreases and then gradually increases, thus constructing a structure where the cross-sectional area of ​​the flow channel gradually decreases and then gradually increases, etc. The connecting channel 143 adopts a tapered-widening structure (Venturi effect) connection, utilizing the change in flow velocity to improve the uniformity of the mixing of high-temperature flue gas and spray. The interface between the atomizing chamber and the mixing chamber 132 adopts a Venturi tapered-widening design to ensure sufficient mixing and evaporation of the spray and the high-temperature flue gas.

[0079] Optionally, the connection channel 143 of this utility model can be configured as one or more segments.

[0080] For example, such as Figure 3 In some embodiments, the connection channel 143 may include a first connection segment 1431, which is located in the upstream portion of the connection channel 143 and configured to gradually decrease in cross-sectional area in the direction from the humidification component 12 to the mixing component 13.

[0081] For example, such as Figure 3 In some embodiments, the connection channel 143 may include a second connection segment 1432, which is located in the downstream portion of the connection channel 143 and configured to gradually increase the cross-sectional area of ​​the flow channel in the direction from the humidification component 12 to the mixing component 13.

[0082] For example, such as Figure 3 The connecting channel 143 may include a first connecting segment 1431 and a second connecting segment 1432. The first connecting segment 1431 is configured such that the cross-sectional area of ​​the flow channel gradually decreases in the direction from the humidifying component 12 to the mixing component 13, and the second connecting segment 1432 is configured such that the cross-sectional area of ​​the flow channel gradually increases in the direction from the humidifying component 12 to the mixing component 13. The first connecting segment 1431 and the second connecting segment 1432 are connected along the direction from the humidifying component 12 to the mixing component 13, forming a structure in which the cross-sectional area of ​​the flow channel first gradually decreases and then gradually increases. Of course, the first connecting segment 1431 and the second connecting segment 1432 may also be configured not to be directly connected. For example, the connecting channel 143 may also include a third connecting segment, which is connected between the first connecting segment 1431 and the second connecting segment 1432. The third connecting segment may be configured as a flow channel with a constant cross-sectional area.

[0083] In some embodiments, the heating component 11 is configured to generate a hot airflow using gas heating. This can improve the heating efficiency of the airflow, thereby improving the heating efficiency and effect. Utilizing gas heating can also improve the stability and safety of the heating component 11, facilitating the stable generation of hot airflow by the heating component 11.

[0084] like Figure 2 and Figure 3 The heating assembly 11 includes a first housing 111, a burner 112, and a fan 113. The burner 112 is disposed within the first housing 111, and the first housing 111 has a combustion chamber communicating with a mixing chamber 132. At least a portion of the burner 112 is disposed within the combustion chamber. The burner 112 is configured to generate a hot airflow by heating the gas. The fan 113 is configured to input airflow into the first housing 111 and, after passing through the burner 112, input it into the humidification assembly 12. During use, gas and air are input into the burner 112, and after the gas and air are mixed in a predetermined ratio, the mixed airflow is ignited by an igniter 114. The burner 112 heats the airflow by burning the gas, and the fan 113 drives the airflow to circulate, thereby forming a hot airflow.

[0085] In addition, such as Figure 2 and Figure 3The heating assembly 11 may also include an igniter 114, and a burner 112 disposed in the first housing 111 for generating a hot gas flow by burning gas. The igniter 114 is used to ignite the gas ejected from the burner 112. A fan 113 is used to drive the hot gas flow into the mixing unit. Under the action of the fan 113, external air can quickly enter into the first housing 111 and can be premixed with the gas in the burner 112 to improve the combustion efficiency of the burner 112 and reduce the emissions of nitrogen oxides and carbon monoxide. After the igniter 114 is successfully ignited, a hot gas flow is generated. Driven by the fan 113, the hot gas flow enters the mixing unit for mixing to accelerate the flow rate of the hot gas flow into the mixing unit.

[0086] For example, when the combustion unit operates alone and the humidification unit is not activated, the igniter 114 ignites the gas ejected from the burner 112, causing the gas to burn continuously and generate a hot gas flow. The ignition component does not need to be ignited multiple times. The mixing unit can be used to receive and output the hot gas flow. The fan 113 draws in external air and forms a driving airflow to drive the hot gas flow into the mixing unit. The hot gas flow can flow through the mixing unit and be continuously output to the space that needs to be heated, so as to raise the temperature of the space that needs to be heated, so that the combustion unit can heat the space alone.

[0087] Optionally, the fan 113 can be a variable frequency fan. The variable frequency fan can control the air volume by adjusting the motor speed, which avoids the ineffective energy consumption of the fixed frequency fan when it runs at a fixed speed. It can also avoid the high current surge when the fixed frequency fan starts, thereby reducing the wear of the motor and related components and extending the service life of the equipment. At the same time, the variable frequency fan generates relatively low noise when running at low speed, which helps to improve the working environment.

[0088] Ignition 114 can be configured for intermittent ignition to control the output flue gas temperature of the combustion unit. When the temperature inside the mixing unit is lower than the set temperature, combustion gas can be introduced into the burner 112, and ignition 114 can ignite the combustion gas to generate high-temperature flue gas, which is then introduced into the mixing unit to increase the temperature inside the mixing unit. When the set temperature is reached inside the mixing unit, both burner 112 and ignition 114 can stop operating. Intermittent ignition by ignition 114 ensures that the temperature inside the mixing unit remains within a certain range, improving the mixing efficiency of the hot gas flow and the mixed gas flow.

[0089] For example, when the mixing unit needs to output mixed airflow to the cooking cavity 201, the humidifying unit can be fully turned on, the burner 112 can be supplied with gas, and the igniter 114 can ignite the gas and generate high-temperature flue gas, which is then introduced into the mixing unit to increase the temperature inside the mixing unit. The humid airflow may include water droplets or water mist, and the mixed airflow may include steam. After the high-temperature flue gas and water droplets come into contact and exchange heat in the mixing unit, steam can be generated. A small amount of flue gas and a large amount of steam are simultaneously delivered to the cooking cavity 201 to enhance the heating effect of the heating device 10. When the mixing unit reaches a certain temperature, the burner 112 can stop working, and the high-temperature flue gas remaining in the mixing unit can be mixed with the humid airflow to save energy consumption. When the temperature inside the mixing unit is lower than the set temperature, the igniter 114 can re-ignite the burner 112, and the burner 112 restarts, providing sufficient high-temperature flue gas to the mixing unit to ensure that the temperature inside the mixing unit is higher than the set temperature, so that the humid airflow can absorb the heat of the high-temperature flue gas and convert it into mixed airflow.

[0090] The cooking device 100 in this embodiment of the present invention eliminates the heat exchanger in the steam generator of the related technology. The humidity of the hot airflow is directly adjusted by the humidification component 12. The humidified hot airflow enters the cooking chamber 201, thereby adjusting the humidity in the cooking chamber 201, improving the heating efficiency of the cooking device 100, reducing the production cost of the cooking device 100, allowing for more space inside the cooking device 100, and reducing the emission of pollutants such as nitrogen oxides, making it more environmentally friendly.

[0091] In addition, the structure of the humidification component 12 in this utility model may include, but is not limited to, the following embodiments.

[0092] Example 1, as Figure 2 and Figure 3 In some embodiments, the humidifying component 12 includes a second housing 121 and an atomizer 122. The second housing 121 has an atomizing chamber communicating with the heating component 11 and the mixing component 13; the atomizer 122 is disposed in the atomizing chamber. The atomizer 122 can be used to atomize the water in the second housing 121 to generate a humidified airflow, simplifying the structure of the humidifying component 12. Furthermore, the flow rate of the humidified airflow can be controlled by manipulating the atomizer 122, thereby improving cooking efficiency and effectiveness. Additionally, the second housing 121 may include a water tank for storing water, and the atomizer 122 may be disposed within the water tank.

[0093] Optionally, the humidification component 12 can be configured to control the vibration frequency of the atomizer 122 according to humidity requirements. This adjusts the atomization volume to ensure sufficient humidifying airflow from the humidification unit to the mixing unit, guaranteeing that the humidity within the mixing unit meets the user's desired humidity level. For example, when the humidity requirement within the mixing unit is high, the vibration frequency of the atomizer 122 can be increased to increase the atomization volume, allowing the atomizer 122 to generate more humidifying airflow; conversely, when the humidity requirement within the mixing unit is low, the vibration frequency of the atomizer 122 can be decreased to reduce the atomization volume, thus reducing the flow rate of the humidifying airflow generated by the atomizer 122 and lowering the humidity within the mixing unit. By controlling the vibration frequency of the atomizer 122, the humidity within the mixing unit is maintained at the user's desired level, improving the user experience. Furthermore, the number of atomizers 122 can be multiple, including two, three, four, or even more. The humidification component 12 can be configured to control the number of atomizers 122 in operation according to humidity requirements.

[0094] In Example 2, the humidification component 12 may include a nozzle for generating atomized water to regulate the humidity of the hot airflow. For example, before entering the cooking chamber 201, water mist can be sprayed from the nozzle to humidify the airflow. The atomized water absorbs the heat of the hot airflow and generates water vapor. The hot airflow carries the water vapor and enters the cooking chamber 201, increasing the humidity inside the cooking chamber 201 and preventing moisture loss from the food. This can accelerate the generation of atomized water. The heating component 11 can generate flue gas by burning gas. That is, the hot airflow contains flue gas. The flue gas combines with the atomized water and quickly generates water vapor. The flue gas can carry the water vapor and quickly enter the cooking chamber 201, exchanging heat with the air inside the cooking chamber 201 to increase the temperature of the cooking chamber 201 and heat the food. Alternatively, the hot airflow carrying water vapor can be blown directly onto the surface of the food. The water vapor can be evenly sprayed onto the surface with the flue gas, avoiding localized over-humidity or dryness inside the cooking chamber 201 and improving the heating efficiency of the cooking equipment 100.

[0095] In Example 3, the humidification component 12 includes a heater for heating water to generate steam to regulate the humidity of the hot airflow. Before entering the cooking chamber 201, the steam generated by the humidification component 12 mixes with the hot airflow. The hot airflow carries the steam and enters the cooking chamber 201, increasing the humidity inside the cooking chamber 201 and preventing moisture loss from the food. The humidification component 12 may include a heater. By heating the water and generating steam, the heater can more precisely control the amount of steam generated, thereby accurately regulating the humidity of the hot airflow. The heating component 11 burns gas to generate flue gas, meaning the hot airflow contains flue gas. The flue gas can carry steam and quickly enter the cooking chamber 201, exchanging heat with the air inside the cooking chamber 201 to increase the temperature of the cooking chamber 201 and heat the food. Alternatively, the hot airflow carrying steam can be directly blown onto the surface of the food, allowing the steam to be evenly sprayed onto the surface with the flue gas, preventing localized over-humidity or dryness within the cooking chamber 201 and improving the heating efficiency of the cooking equipment 100.

[0096] In some embodiments, the cooking device 100 also includes a temperature sensor for detecting the temperature of the hot airflow entering the cooking chamber 201. The cooking device 100 is configured to adjust the power of the heating component 11 or the power of the humidifying component 12 according to the temperature of the hot airflow, thereby precisely controlling the temperature inside the cooking chamber 201 and dynamically adjusting the power of the heating component 11 or the humidifying component 12 to maintain the temperature inside the cooking chamber 201 at the temperature required by the user, thereby improving the user experience.

[0097] For example, the temperature sensor can monitor the temperature of the hot airflow entering the cooking cavity 201 in real time. If the temperature inside the cooking cavity 201 is greater than or equal to the temperature set by the user, the cooking device 100 can reduce the power of the heating component 11 to reduce the generation of hot airflow. Alternatively, the cooking device 100 can appropriately increase the power of the humidifying component 12 so that the humidifying component 12 can generate more humid airflow. The humid airflow mixes with the hot airflow and absorbs the heat of the hot airflow, thereby reducing the temperature of the hot airflow and thus reducing the temperature inside the cooking cavity 201. This keeps the temperature inside the cooking cavity 201 at the temperature required by the user, improving the user experience.

[0098] In addition, if the temperature inside the cooking cavity 201 is lower than the target temperature set by the user, the cooking device 100 can increase the power of the heating component 11 to increase the generation of hot airflow, allowing more hot airflow to enter the cooking cavity 201 and increase the temperature inside the cooking cavity 201; or, the cooking device 100 can appropriately reduce the power of the humidifying component 12 to reduce the generation of humid airflow, allowing hotter airflow to enter the cooking cavity 201, thereby increasing the temperature inside the cooking cavity 201.

[0099] In some embodiments, the cooking device 100 also includes a humidity sensor for detecting the humidity of the hot airflow entering the cooking cavity 201. The cooking device 100 is configured to adjust the power of the heating component 11 or the humidification component 12 according to the humidity of the hot airflow, thereby precisely controlling the temperature inside the cooking cavity 201 and dynamically adjusting the power of the heating component 11 or the humidification component 12 to maintain the temperature inside the cooking cavity 201 at the temperature required by the user, thereby improving the user experience.

[0100] For example, a humidity sensor can monitor the humidity inside the cooking cavity 201 in real time. If the humidity inside the cooking cavity 201 is greater than or equal to the target humidity set by the user, the cooking device 100 can increase the power of the heating component 11 to increase the generation of hot airflow. More hot airflow enters the cooking cavity 201, which can accelerate the evaporation of moisture inside the cooking cavity 201 and reduce the humidity inside the cooking cavity 201. Alternatively, the humid airflow can be mixed with the hot airflow, and the humidity of the hot airflow can be adjusted. The cooking device 100 can appropriately reduce the power of the humidifying component 12 to reduce the generation of humid airflow. The humidity of the hot airflow is reduced, thereby reducing the humidity inside the cooking cavity 201, so that the humidity inside the cooking cavity 201 is maintained at the humidity required by the user, improving the user experience.

[0101] In addition, if the humidity inside the cooking cavity 201 is less than the target humidity set by the user, the cooking device 100 can reduce the power of the heating component 11 to reduce the generation of hot airflow; or, the cooking device 100 can appropriately increase the power of the humidifying component 12 to increase the generation of humid airflow, so that more humid airflow mixes with the hot airflow, increasing the humidity of the hot airflow, and allowing the hot airflow with higher humidity to enter the cooking cavity 201, thereby increasing the humidity inside the cooking cavity 201.

[0102] In some embodiments, the heating assembly 11 includes a burner 112 configured to generate the hot gas flow by heating the gas. Alternatively, the heating assembly 11 may also include an electric heater, etc.

[0103] This utility model provides a heating device 10, including components such as a burner 112, a flue 141, a baffle, an atomizing chamber, an atomizer 122, a mixing assembly 13, and a control module. Figure 1 As shown. The hot airflow (e.g., high-temperature flue gas) generated by the burner 112 enters the atomization chamber through the flue 141. The atomizer 122 turns on to atomize, and the generated spray is entrained by the flue gas and enters the mixing chamber 132 of the mixing component 13 together. The water mist mixes with the hot airflow and evaporates into water vapor, which then enters the cooking chamber 201 to process the food.

[0104] Figure 2 and Figure 3 Cross-sectional views of the main components are provided, such as... Figures 4 to 8Flue 141 includes flow paths (there can be one, two, or more than three flow paths), such as Figure 4 , Figure 6 ,and Figure 8 The internal flow path employs a Tesla valve design, such as Figure 6 , Figure 7 and Figure 8 As shown, to prevent the spray and water vapor in the humidification component 12 from flowing back into the burner 112 and affecting combustion, and to increase the flow rate of the hot airflow and enhance the Venturi effect, there are two baffles at the inlet of the flue 141. By adjusting these baffles, the inlets of the flue 141 on the left and right sides can be blocked, thereby adjusting the flow area of ​​the flue 141 to adapt to different operating conditions.

[0105] like Figures 2 to 4 Between the second housing 121 and the mixing component 13, a tapered-widening design at their connection point, combined with a Tesla valve design inside the flue 141, allows hot air to be ejected at a higher velocity in the atomizing chamber. This creates negative pressure in the tapered section of the connecting channel 143, entraining the spray generated by the ultrasonic atomizer 122 and improving mixing efficiency. In the widening section of the connecting channel 143, the mixing airflow velocity decreases and gradually diffuses throughout the mixing chamber 132, providing ample time for the spray to evaporate into water vapor.

[0106] During the operation of the cooking equipment 100 (such as an oven, gas oven, steam oven, or gas-steam oven), the flow area of ​​the flue 141 is determined according to the power and operating mode. In single-bake mode, when running at full load, all baffles are open, maximizing the flow area of ​​the flue 141 to reduce flow resistance. In single-steam mode, the baffles are fully closed, leaving only the central flow path open to increase the flow rate of hot air in the atomization chamber, enhance the entrainment effect, and ensure thorough mixing of the hot air and the spray. In wet-bake mode, the opening and closing of the baffles are adjusted according to specific needs to adapt to different operating conditions.

[0107] The baffle is driven by a stepper motor and is made of high-temperature resistant alloy. It can be 310S stainless steel (containing high chromium and nickel: 25% Cr and 20% Ni, with an oxidation resistance temperature of up to 1120°C) or Inconel alloy (such as Inconel 625, with a high temperature resistance of up to 980°C, corrosion resistance, and high humidity resistance). The surface coating can be further strengthened by using high-temperature ceramic coatings, such as alumina or silicon carbide coatings, to improve wear resistance and thermal shock resistance. At the same time, the sealing layer can be made of graphite-based composite materials, such as flexible graphite sheets or expanded graphite tapes, as the sealing surface layer, utilizing the self-lubricating properties and high-temperature stability of graphite to reduce frictional leakage.

[0108] In this invention, the flue 141 adopts a variable cross-section design, which can adjust the flow rate of hot air and adapt to the mixing efficiency of hot air and spray under different working conditions. The Tesla valve design inside the flue 141 improves the flue gas flow rate while effectively preventing water vapor backflow in the atomization chamber. The connection between the atomization chamber and the mixing chamber 132 adopts a gradually narrowing-widening Venturi tube structure to ensure more uniform mixing of high-temperature flue gas and spray.

[0109] In addition, the smoke exhaust assembly may include a third housing 131, which has a mixing chamber 132. Hot air can pass through the second housing 121 into the mixing chamber 132 and finally be output from the smoke exhaust port 133.

[0110] like Figure 9 and Figure 10 According to an embodiment of the present utility model, the cooking device 100 includes: a device body 20 and the aforementioned heating device 10. The device body 20 includes a cooking cavity 201; the heating device 10 is disposed on the device body 20, and the smoke outlet is connected to the cooking cavity 201.
