[0030] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0031] The cooking appliances in this application include steam ovens, steamers and ovens. Steamers use electronic control to precisely control temperature and time, making cooking more accurate and efficient. Steamers can well preserve the natural color, nutrients and original flavor of food, and are particularly suitable for cooking seafood, vegetables and pastries. Ovens usually use electric heating elements to generate heat, and achieve uniform heating through hot air circulation or up and down heating. They are widely used in baking bread, cakes, barbecues and vegetables. Steam ovens are modern kitchen appliances that combine the characteristics of traditional steamers and ovens, aiming to provide more diverse cooking options. It not only saves kitchen space, but also allows users to try more creative dishes on the same device through intelligent control technology, such as steamed and roasted chicken, quick fermentation of dough, etc.

[0032] The core components of the steamer include a water tank, a steam generator and a circulation system. The water in the water tank is heated to boiling to generate steam, which is then transported into the steamer through pipes and circulates around the food, thereby evenly heating the food.

[0033] The key components of an oven include heating elements (such as resistance wire heating tubes), fans (for hot air circulation) and temperature control systems. The heating elements generate heat energy, and the fans help hot air circulate in the box to ensure even heat distribution; the temperature control system adjusts the working state of the heating elements according to the set temperature.

[0034] The steam oven has a more complex control system based on the basic structure of a steam box and an oven. It usually includes a mainboard, a circuit board, a temperature sensor, a heating element, a fan, a water tank, and a steam generator. As the control core, the mainboard intelligently regulates the operation of the heating element and the steam generator according to the cooking mode selected by the user, achieving a variety of cooking effects such as pure steaming, pure baking, or a combination of steaming and baking. During use, since there is only a digital temperature display on the display panel, it is not intuitive, and there is no clear temperature inside the box. When the box is opened, steam will rush out, and there is no temperature display after cooking. The user is not clear about the actual temperature of the box. Opening the box that has just been cooked may cause scalding by the high temperature of the steam, which seriously affects the user experience.

[0035] In order to solve the above technical problems, the present disclosure provides a high temperature steam warning system. Figure 1-Figure 3 The high-temperature steam warning system is applied to a handle 3 of a cooking utensil, comprising:

[0036] Box 1;

[0037] A box door 2, one side of which is hingedly connected to the box body 1;

[0038] A handle 3 is provided on the door 2;

[0039] The temperature detection device 7 is arranged in the box body 1 and is used to detect the temperature in the box body 1;

[0040] A humidity detection device 8 is arranged in the box body 1 and is used to detect the humidity in the box body 1;

[0041] A display module 4, disposed on the handle 3, for emitting a light signal;

[0042] The control module is respectively connected with the temperature detection device 7 , the humidity detection device 8 and the display module 4 through electrical signals. The control module receives the detection results of the temperature detection device 7 and the humidity detection device 8 , and outputs them to the display module 4 .

[0043] In the steam oven, when the user selects the steaming function, the steam generator starts to generate high-temperature steam and transports it into the box body 1. However, when the cooking program is finished, it is difficult for the user to understand the specific situation of the high-temperature steam in the box body 1.

[0044] Based on the above configuration, the high-temperature steam warning system is equipped with multiple different detection modules. Based on the multiple different detection modules, the temperature data and humidity data in the box 1 can be detected. According to the detected temperature data and humidity data, it is determined whether there is a risk of high-temperature steam, and the display module 4 is controlled to send a light signal to remind the user.

[0045] Based on the above concept, a specific embodiment is provided. Please refer to Figure 1-Figure 2 , a steam oven is provided, including: a box body 1, a box door 2, a handle 3, a high temperature probe, a humidity probe, an LED light and a control module. It should be noted that the shape and size of the cooking utensil box body 1 are not limited in the embodiment of the present disclosure. It can be an electric rice cooker, a steamer, an oven or a steam oven. The embodiment of the present disclosure is applied to cooking utensils that use high-temperature steam for cooking.

[0046] In addition, the embodiments of the present disclosure do not limit whether the cooking appliance has a handle 3. For example, the embodiments of the present disclosure may also be arranged on the door frame of a steamer door having a built-in groove.

[0047] The present embodiment does not limit the type of the temperature detection device 7, which may be a high temperature probe or an infrared thermometer. Preferably, the high temperature probe has a lower production cost. Similarly, the present embodiment does not limit the type of the humidity detection device 8, which may be a steam humidity sensor or a humidity probe. Preferably, the humidity probe has a lower production cost.

[0048] This embodiment does not limit the number and position of the temperature detection device 7 and the humidity detection device 8 in the box. It can be a single set of temperature detection devices 7 and humidity detection devices 8, or multiple sets of temperature detection devices 7 and humidity detection devices 8. They can be installed at the bottom of the cooking cavity, or at the top of the cooking cavity, or at various corners of the cooking cavity. This embodiment is to collect temperature data of high-temperature steam, that is, temperature data in the cooking cavity.

[0049] In addition, this embodiment does not limit the type and display method of the display module 4 on the handle 3. It can be an LED light or an electronic display screen. It can remind the user through light signals of different colors, or through the flashing frequency of the light signal, or through a combination of sound signals and light signals. This embodiment is intended to more intuitively remind the user of the risk of scalding by high-temperature steam.

[0050] In order to more intuitively remind users of the risk of scalding by high-temperature steam, please refer to Figure 3The display module is arranged on the handle 3 of the cooking utensil, the display module 4 is arranged as an LED light, and the LED light includes a red light and a white light, the red light and the white light are evenly distributed side by side on the handle 3, when there is a risk of scalding by high-temperature steam, the red light is on, on the contrary, when there is no risk of scalding by high-temperature steam, the white light is on, in addition, a sensing device 6 is also arranged at both ends of the handle 3, wherein the type of the sensing device 6 can be one of an infrared tube detection sensor, an infrared pyroelectric detection sensor or a microwave detection sensor, and the utility model does not limit the type of the sensing device 6.

[0051] The sensing device 6 is connected to the control module by electrical signals. The sensing device 6 is used to sense the distance between the user and the cooking utensil. The control module switches different high-temperature steam emission modes according to the collected sensing distance to reduce the risk of the user being scalded by high-temperature steam.

[0052] After the cooking appliance starts cooking, the high-temperature steam warning system is activated. When there is high-temperature steam in the cooking cavity, the control display module sends a light signal to remind the user of the risk of scalding by high-temperature steam. After the cooking program is over, the high-temperature steam warning system still works until the user opens the cavity door, then the high-temperature steam warning system is turned off.

[0053] In another specific embodiment, please refer to Figure 4 , a steam oven is provided, including a cooking cavity and a forced exhaust module, and also including a high-temperature steam warning system, the forced exhaust module is used to exhaust the gas in the cooking cavity, wherein the cooking cavity is used to place food, and the heating element in the cooking utensil is used to heat the cooking cavity to cook the food in the cooking cavity, and the forced exhaust module 11 is used to exhaust the gas in the cooking cavity, so that the high-temperature steam can be exhausted more quickly during the waiting stage after the cooking is completed, and when the user opens the door, the amount of high-temperature steam in the cooking cavity that gushes out from the door can be reduced, thereby reducing the risk of scalding to the user and reducing the waiting time for the user.

[0054] Optionally, the cooking appliance also includes a condensation module 12, which is arranged at the exhaust port of the cooking cavity, and is used to condense the high-temperature steam discharged from the cooking cavity, and return the condensed water to the cooking cavity through gravity, thereby improving water utilization, reducing the discharged high-temperature steam, and reducing the risk of users being scalded by high-temperature steam.

[0055] The cooking appliance further comprises a water supply system, which comprises a water pipe and a solenoid valve. The water pipe is arranged at the rear of the box body 1, and the solenoid valve is arranged at the inlet of the water pipe.

[0056] Exemplarily, the forced exhaust module 11 includes a blower and a pipeline, the air outlet of the blower in the forced exhaust module 11 is connected to one end of the pipeline, the other end of the pipeline is connected to the cooking chamber, the forced exhaust module 11 is connected to the control module, and the control module is used to control the opening and closing of the blower. When the target distance is greater than the preset distance, the control module can control the blower to turn on, so that the forced exhaust module 11 can deliver gas to the cooking chamber. At this time, the blower delivers cold air to the pipe, and the cold air generated by the blower enters the cooking cavity through the pipe, thereby squeezing the high-temperature steam in the cooking cavity, so that the high-temperature steam in the cooking cavity can be quickly discharged through the exhaust port of the cooking cavity and help cool the cooking cavity, thereby improving the efficiency of discharging high-temperature steam. In this way, high-temperature steam can be discharged more quickly during the waiting stage after cooking is completed. When the user opens the door, the amount of high-temperature steam in the cooking cavity that flows out of the door can be reduced, thereby reducing the risk of scalding the user and reducing the waiting time for the user. When the target distance is less than or equal to the preset distance, the control module can control the blower to close, thereby reducing the efficiency of discharging high-temperature steam from the exhaust port of the cooking cavity, and avoiding scalding the user in the process of discharging high-temperature steam.

[0057] For example, the condensation module 12 includes a phase change condensation plate. A phase change material is provided in the phase change condensation plate. The high-temperature steam entering the condensation module 12 transfers heat to the phase change condensation plate through the condensation fins. The phase change material in the phase change condensation plate absorbs heat and heats up accordingly. When the phase change material reaches its phase change temperature, a physical change occurs, such as from liquid to gas, so that the high-temperature steam contacting the phase change condensation plate can absorb a large amount of heat in a short time and quickly condense into liquid condensed water. At the same time, the phase change condensation plate continuously exchanges heat with the pipe shell of the condensation module 12, so that the phase change material in the phase change condensation plate returns to its original state for recycling.

[0058] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
