[0029] This application is based on the inventor's discoveries and understanding of the following facts and problems:

[0030] In related technologies, cooking appliances such as steam ovens have a slow rate of steam filling the cooking cavity during cooking, resulting in a slow temperature rise in the cooking cavity and affecting cooking efficiency and cooking results.

[0031] Specifically, in the steam oven of the relevant technology, steam is injected into the cooking cavity through the nozzle at a certain speed. Because the steam is injected at a relatively fast speed, the steam is mainly concentrated on the path of the extension direction of the nozzle, and it takes a long time to gradually fill other parts of the cooking cavity, resulting in a slow filling speed and a slow heating of the cooking cavity, which affects the cooking efficiency and cooking effect.

[0032] Embodiments of the present invention 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.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The steam inlet structure 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1-3 As shown, the steam inlet structure 1 according to an embodiment of the present invention includes a housing 10 and flow divider fins 20.

[0037] The housing 10 has a cooking chamber 11 and a steam distribution chamber 12 connected to the cooking chamber 11. The housing 10 is provided with an air inlet 13 connected to the steam distribution chamber 12. The flow divider fins 20 are located in the steam distribution chamber 12.

[0038] Specifically, steam first enters the steam distribution chamber 12 through the air inlet 13, and after being diverted and guided by the diversion fins 20 in the steam distribution chamber 12, it gradually flows to the cooking chamber 11.

[0039] According to the steam inlet structure 1 of the present invention, by providing diversion fins 20, after the steam enters the steam distribution chamber 12 through the air inlet 13, the diversion fins 20 can be used to divert and guide the steam, so that the steam is dispersed in the steam distribution chamber 12, avoiding the steam from being too concentrated, and making the steam evenly dispersed to fill the cooking chamber 11, so that the steam forms an integral steam layer. As the steam fills, it squeezes out the air without mixing with the air, which facilitates the steam to quickly fill the cooking chamber 11, improves the steam filling efficiency, thereby improving the steam inlet efficiency of the steam inlet structure 1 and improving the heating speed of the cooking chamber 11.

[0040] Therefore, the steam inlet structure 1 according to the embodiment of the present invention has the advantages of high steam inlet efficiency and fast filling speed.

[0041] The steam inlet structure 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0042] In some specific embodiments of the present invention, such as Figures 1-3 As shown, the steam inlet structure 1 according to an embodiment of the present invention includes a housing 10 and flow divider fins 20.

[0043] Specifically, such as Figure 1 and Figure 2 As shown, the steam distribution chamber 12 is located above the cooking chamber 11. In this way, after the steam is diverted by the diversion fins 20, it can gradually fill the cooking chamber 11 by settling downwards, thereby improving the steam filling efficiency of the cooking chamber 11.

[0044] More specifically, such as Figure 1 As shown, the lower surface of the steam distribution chamber 12 is open to connect with the cooking chamber 11. This facilitates the connection between the steam distribution chamber 12 and the cooking chamber 11, avoids obstructing the flow of steam, and improves the steam filling efficiency.

[0045] Advantageously, such as Figure 1As shown, the flow divider fins 20 are formed on the top wall of the steam distribution chamber 12. This facilitates the placement of the flow divider fins 20 and allows steam to flow into the cooking chamber 11.

[0046] More advantageously, such as Figure 1 and Figure 3 As shown, there are multiple diversion fins 20 arranged at intervals. This allows multiple diversion fins 20 to divert and guide the steam, improving the steam dispersion effect and facilitating the uniform distribution of steam into the cooking cavity 11, thereby increasing the steam filling efficiency of the cooking cavity 11.

[0047] Furthermore, in the air intake direction, the distance between every two adjacent diversion fins 20 gradually increases. It is important to understand that "air intake direction" refers to the flow direction of steam entering through the air intake 13, as shown by arrow a in the figure. Since the steam's velocity gradually decreases as the flow distance increases after entering the steam distribution chamber 12 through the air intake 13, by rationally arranging the spacing of the diversion fins 20, the steam can be more evenly dispersed into the cooking chamber 11, further improving the steam filling efficiency of the cooking chamber 11.

[0048] Figures 1-3 An inlet structure 1 according to a specific example of the present invention is shown. For example... Figures 1-3 As shown, the projections of the diversion fins 20 and the air inlet 13 in a plane perpendicular to the air intake direction are offset. This helps to ensure the steam flow rate in the air intake direction and avoids insufficient downstream steam due to excessive diversion of steam by the diversion fins 20, thus allowing the steam to enter the cooking chamber 11 more evenly.

[0049] Specifically, such as Figure 1 and Figure 3 As shown, the steam distribution chamber 12 includes a clearance space directly opposite the air inlet 13, which divides the steam distribution chamber 12 into two steam distribution spaces. A flow-dividing fin 20 is disposed within at least one of the steam distribution spaces. This allows the flow-dividing fin 20 within the steam distribution space to divert steam, facilitating uniform steam dispersion.

[0050] More specifically, such as Figure 1 and Figure 3 As shown, each of the steam distribution spaces has multiple diversion fins 20 arranged at intervals along the air intake direction. In this way, the diversion fins 20 in the two steam distribution spaces can be used to divert the steam discharged from the air intake 13 from both sides, thereby improving the steam dispersion effect and making the steam enter the cooking cavity 11 more evenly.

[0051] Advantageously, such as Figure 1 and Figure 3As shown, the flow divider fins 20 extend obliquely in the air intake direction from one end near the clearance space to the end away from the clearance space. This reduces obstruction to the steam while achieving steam diversion, facilitating the dispersion of steam to various parts of the steam distribution chamber 12.

[0052] More advantageously, such as Figure 1 and Figure 3 As shown, the flow divider fins 20 in the two steam distribution spaces are symmetrically arranged. This not only facilitates the manufacturing of the steam inlet structure 1, but also makes the steam distribution more uniform.

[0053] Optionally, such as Figure 1 and Figure 3 As shown, the end faces of the flow divider fins 20 are spaced apart from the inner circumferential surface of the steam distribution chamber 12. This facilitates steam diffusion and saves material on the flow divider fins 20, reducing the cost of the steam inlet structure 1.

[0054] Furthermore, such as Figures 1-3 As shown, the air inlet 13 is formed on the left or right side wall of the steam distribution chamber 12, and multiple diversion fins 20 are spaced apart in the left-right direction. This facilitates the connection between the air inlet 13 and the steam source.

[0055] Specifically, the steam inlet can be connected to a steam source. The steam source can be provided by a heating device.

[0056] The heating device according to an embodiment of the present invention is described below.

[0057] The heating device according to an embodiment of the present invention includes a water tank, electrodes, a conductivity detection device, and a controller.

[0058] Electrodes are used to heat the water in the tank. A conductivity detection device measures the conductivity of the water in the tank. A controller is electrically connected to both the electrodes and the conductivity detection device to adjust the voltage of the electrodes according to the conductivity.

[0059] According to the heating device of the present invention, by setting electrodes, the water in the water tank is heated by the electrodes. Compared with the heating devices in the related art, the water itself is heated as a resistive medium, which can reduce the accumulation of scale, avoid affecting the heating efficiency of the heating device, and avoid the heating device from being blocked or even burned out.

[0060] Furthermore, due to differences in water quality, the conductivity of water as a resistive medium varies, resulting in different heating power for the water at the same voltage, making it difficult to control the heating power. By setting up a conductivity detection device and a controller, the voltage of the electrodes can be adjusted according to the conductivity, which facilitates the control of heating power compared to related technologies, avoiding excessive or insufficient heating power that could affect the heating effect.

[0061] Therefore, the heating device according to the embodiments of the present invention has advantages such as being less prone to scale buildup, high heating efficiency, and good heating effect.

[0062] Specifically, there are two electrodes arranged at intervals. This allows the water between the two electrodes to form a resistive medium, and by energizing the water between the two electrodes, the water between the two electrodes can be directly heated, avoiding scale buildup.

[0063] Optionally, the two electrodes are spaced apart in the horizontal direction. This facilitates the arrangement of the electrodes and allows both electrodes to enter or exit the water simultaneously when the water level changes.

[0064] Specifically, when the water level in the tank drops below the electrodes, the two electrodes are no longer conductive by the water, and the electrical connection between them is naturally broken, preventing dry burning. This not only avoids dry burning and ensures the reliability of the heating device, but also eliminates the need for protection devices, reducing costs.

[0065] More specifically, the electrodes are mounted inside the water tank via mounting brackets. This facilitates the installation of the electrodes within the water tank and makes their orientation and positioning easier.

[0066] In one specific embodiment, the mounting base is located on the bottom wall of the water tank, and the electrodes are oriented vertically. This allows the electrical connection between the electrodes to be broken when the water level drops to near the bottom wall, facilitating control of the water tank's volume.

[0067] In another specific embodiment, the mounting base is located on the side wall of the water tank and adjacent to the bottom wall, with the electrodes oriented horizontally. This allows the electrical connection between the electrodes to be broken when the water level drops to near the bottom wall, facilitating control of the water tank's volume.

[0068] Specifically, the heating device also includes a frequency converter, and the controller is electrically connected to the electrodes via the frequency converter. This allows the frequency converter to adjust the electrode voltage, facilitating control of the electrode voltage.

[0069] Optionally, the conductivity detection device includes a TDS (Total Dissolved Solids) detection device. This allows the electrode voltage to be calculated based on the conductivity of the water body, provided the TDS detection device provides feedback.

[0070] More specifically, the controller adjusts the electrode voltage according to the TDS detection value so that the electrode voltage is proportional to the detection value. It's important to understand that "the electrode voltage is proportional to the detection value" is true without considering the target power. In other words, with a constant target power, the electrode voltage needs to be proportional to the detection value. This facilitates control of the heating power of the heating device, preventing excessively high or low heating power from affecting the heating effect.

[0071] The water tank is equipped with a steam outlet. The steam generated by heating the water in the tank with electrodes can then be discharged through the steam outlet and further guided into the cooking chamber of the cooking appliance, enabling steam cooking of food.

[0072] Advantageously, the steam outlet is located at the top of the water tank. This facilitates control of the maximum water storage capacity of the tank, the volume of the tank, and the discharge of steam.

[0073] In one embodiment, the steam outlet may be formed on the top wall of the water tank.

[0074] In another embodiment, the steam outlet may be formed on the side wall of the tank and adjacent to the top wall.

[0075] Optionally, the electrode is a graphite electrode. This not only reduces scale buildup on the electrode but also lowers costs.

[0076] Specifically, the electrodes are plate-shaped or columnar. This facilitates the heating of the water.

[0077] The working process of the heating device according to an embodiment of the present invention is described below.

[0078] When the water tank is low on water, the two electrodes are disconnected, the heating device automatically shuts off, and no steam is generated.

[0079] When water is added to the tank until the electrode is conductive, the heating device is in a conductive state. The graphite electrode uses the resistance of the water in the tank itself, with the water itself acting as a resistive medium, to heat the water and generate steam.

[0080] Simultaneously, the TDS detection device measures the TDS value of the water and feeds it back to the controller. The controller calculates the conductivity based on the TDS value, reflecting the resistivity of the water, and calculates the voltage value based on the target power value, feeding it back to the frequency converter to adjust the output voltage. This enables variable power adjustment of the heating element under different water hardness conditions.

[0081] Specifically, the cooking cavity can also be connected to a steam intake device and a steam extraction device. The steam intake device can be connected to or constituted by the heating device.

[0082] The extraction device and the steam inlet device operate simultaneously for at least a period of time.

[0083] According to the steam circuit system of the present invention, by providing an air extraction device, the air in the cooking cavity can be extracted to avoid the residual air affecting the steam intake speed and improve the steam intake efficiency of the steam circuit system.

[0084] Specifically, when used in steam cooking appliances, it can increase the rate at which steam fills the cooking chamber, thereby improving cooking efficiency and results.

[0085] Furthermore, by enabling the extraction device and the steam inlet device to operate simultaneously for at least a period of time, in other words, by having the steam circuit system extract and inlet steam simultaneously for at least a period of time, compared to the related technical solution of extracting steam first and then inlet steam, the waiting time for users to extract steam can be reduced, the total time required for steam inlet can be shortened, and the steam inlet efficiency can be improved.

[0086] Specifically, when used in steam cooking appliances, it can shorten the total time required for steam filling, reduce user waiting time, and improve cooking efficiency.

[0087] Therefore, the steam circuit system according to the embodiments of the present invention has the advantages of fast steam intake speed and high steam intake efficiency.

[0088] Specifically, the cooking cavity has an exhaust port and a steam inlet port. The exhaust device communicates with the cooking cavity through the exhaust port, and the steam inlet device communicates with the cooking cavity through the steam inlet port. This facilitates communication between the steam inlet device and the exhaust device and the cooking cavity of the cabinet.

[0089] Advantageously, the steam inlet is located at the top of the housing, and the exhaust vent is located at the bottom. This keeps the steam inlet away from the exhaust vent, preventing the exhaust device from drawing out the steam that has just entered the cooking chamber, thus avoiding affecting the steam intake efficiency.

[0090] More advantageously, one of the steam inlet and the exhaust port is located on the side wall of the cooking chamber and the other on the rear wall of the cooking chamber. This allows the steam inlet to be located away from the exhaust port, preventing the exhaust device from drawing out the steam that has just entered the cooking chamber, thereby avoiding affecting the steam intake efficiency.

[0091] Specifically, the extraction device extracts air from the cooking chamber for at least a portion of the cooking process. This improves the steam intake efficiency of the steam circuit system during the cooking phase, thereby increasing cooking efficiency.

[0092] In one specific embodiment of the invention, the gas circuit system further includes a temperature detection device for detecting the temperature inside the cooking cavity, the temperature detection device communicating with the vacuum device. This allows the start and stop timing of the vacuum device to be controlled based on the temperature inside the cooking cavity.

[0093] Specifically, the extraction device stops operating when the temperature detection value is greater than or equal to a predetermined value. This ensures that extraction stops when the temperature inside the cooking cavity reaches the desired level, preventing any impact on subsequent cooking results.

[0094] In another specific embodiment of the invention, the gas circuit system further includes a timing device that stops the vacuum device after it has been running for a predetermined time. This allows for timing control of when the vacuum device stops, preventing any impact on subsequent cooking results.

[0095] Specifically, the steam circuit system also includes a controller that communicates with both the steam inlet device and the exhaust device. This facilitates control over the operation of the steam inlet device and the exhaust device.

[0096] More specifically, the controller controls the steam intake device and the exhaust device to operate simultaneously when cooking begins. In other words, after the cooking appliance receives the cooking command, the steam intake device and the exhaust device operate simultaneously, allowing steam to enter and exit the cooking chamber at the same time, thereby improving the steam intake efficiency of the steam circuit system.

[0097] Optionally, the extraction device is a one-way air pump. This facilitates the extraction of air from the cooking cavity.

[0098] The working process of the vehicle circuit system according to a specific embodiment of the present invention is described below.

[0099] After receiving the cooking command, the cooking appliance operates the steam intake and exhaust devices simultaneously, allowing steam to enter and exit the cooking chamber at the same time. Steam gradually fills the cooking chamber, and the temperature inside the cooking chamber gradually increases as the steam fills. The temperature detection device monitors the temperature inside the cooking chamber in real time. When the temperature reaches the predetermined value, it indicates that the steam inside the cooking chamber has filled to the required level, and the exhaust device stops operating to avoid affecting the subsequent cooking process.

[0100] The following describes a method for controlling a cooking appliance according to an embodiment of the present invention, including the following steps:

[0101] When cooking begins, steam is introduced into the cooking chamber of the cooking appliance, and the cooking chamber is then evacuated.

[0102] The air extraction stops when the temperature of the cooking chamber is greater than or equal to a predetermined temperature.

[0106] The pumping will stop after the predetermined time.
