一种蒸汽阀组件及具有其的烹饪设备Steam valve assembly and cooking equipment with the same
本申请要求于2019年9月19日提交至中国国家知识产权局、申请号为201910890871.8、发明名称为“一种蒸汽阀组件及具有其的烹饪设备”的专利申请的优先权。This application claims the priority of the patent application filed to the State Intellectual Property Office of China on September 19, 2019, with the application number of 201910890871.8 and the invention title of "a steam valve assembly and cooking equipment with the same".
技术领域Technical field
本申请涉及烹饪设备技术领域，具体涉及一种蒸汽阀组件及具有其的烹饪设备。This application relates to the technical field of cooking equipment, and in particular to a steam valve assembly and cooking equipment having the same.
背景技术Background technique
采用蒸煮方式加热食物的蒸煮器具(例如电饭煲)作为一种常用的烹饪器具，广泛应用于人们的日常生活中，为人们的生活带来的不小便利。由于蒸煮器具在工作过程中会产生大量的蒸汽，因此蒸煮器具的盖体上通常设置有蒸汽阀。蒸汽阀的作用是在蒸煮过程中，用于将蒸煮器具内蒸汽的排出。As a commonly used cooking appliance, a cooking appliance (such as an electric rice cooker) that uses a cooking method to heat food is widely used in people's daily life and brings great convenience to people's lives. Since the cooking appliance generates a large amount of steam during operation, the cover of the cooking appliance is usually provided with a steam valve. The function of the steam valve is to discharge steam from the cooking appliance during the cooking process.
众所周知，大火力蒸煮时产热效率高，蒸煮时间快。但是大火力蒸煮会导致热量散失和水蒸气逃逸现象严重，造成食物吸水不足而影响口感。进一步地，为了使蒸煮器具内部形成微压环境，使烹饪后的食物具有良好的口感。现有技术中蒸汽阀排气面积设计均较小，且多为迷宫状的蒸汽通道结构，以便减少热量散失、限制水蒸气逃逸以及对蒸汽的冷凝水进行回收。As we all know, the heat generation efficiency is high during high-fire cooking, and the cooking time is fast. However, high-fire steaming will cause serious heat loss and water vapor escape, resulting in insufficient water absorption of the food and affecting the taste. Furthermore, in order to form a low pressure environment inside the cooking appliance, the cooked food has a good taste. In the prior art, the exhaust area of the steam valve is designed to be small, and most of the steam valve has a labyrinth-shaped steam channel structure to reduce heat loss, limit the escape of water vapor and recover the condensed water of the steam.
在蒸煮加热至沸腾时，食材容易吸收大量的热量，不断产生气泡，上述气泡进入蒸汽阀中，会堆积在蒸汽阀的排气口处出现溢流现象，造成蒸汽阀的阻塞现象，影响锅内蒸汽的正常排出，降低蒸发阀的可靠性，并且溢流还会导致影响食物的口感，并且会给用户清洁带来极大的不便，When the cooking is heated to boiling, the food easily absorbs a lot of heat and continues to produce bubbles. The above-mentioned bubbles enter the steam valve and accumulate at the exhaust port of the steam valve to overflow, causing the steam valve to block and affect the pot. The normal discharge of steam reduces the reliability of the evaporator valve, and the overflow will also affect the taste of the food, and will cause great inconvenience to the user in cleaning.
鉴于此，为了防止气泡溢出，蒸汽阀内部设置各种破泡结构以及用于延长蒸汽流动路径的蒸汽通道，然而这类蒸汽阀不但防溢能力十分有限，而且严重制约了排气量，进而限制了蒸煮器具的加热功率。In view of this, in order to prevent bubbles from overflowing, various bubble-breaking structures and steam passages for extending the steam flow path are arranged inside the steam valve. However, this type of steam valve not only has limited anti-overflow capability, but also severely restricts the exhaust volume, thereby limiting The heating power of the cooking appliance is improved.
由此可以看出，加热功率与蒸汽阀开口面积相互制约，如何平衡加热功率与蒸汽阀开口面积成为亟需解决的问题。It can be seen that the heating power and the opening area of the steam valve are mutually restricted, and how to balance the heating power and the opening area of the steam valve has become an urgent problem to be solved.

本申请实施例同时提供了一种应用于上述实施例中烹饪设备的控制方法。该控制方法主要包括如下步骤：The embodiment of the present application also provides a control method applied to the cooking device in the above embodiment. The control method mainly includes the following steps:
步骤S1：判断食材是否到达沸腾温度；Step S1: Determine whether the food material reaches the boiling temperature;
温度检测通过与控制器电连接的温度传感器实现。温度传感器设置在烹饪空间内，可根据实际情况设置多个。The temperature detection is realized by a temperature sensor electrically connected to the controller. The temperature sensor is arranged in the cooking space, and more than one can be arranged according to the actual situation.
步骤S2：若是，开启蒸汽阀组件，开口面积开至第一状态；Step S2: If yes, open the steam valve assembly, and the opening area is opened to the first state;
食材到达沸腾温度之前，蒸汽阀组件保持关闭状态，即开启面积为0。如此可以避免水蒸气快速逃逸和热量散失，维持水占比，杜绝二次加水的现象，缩短烹饪时间。加热至沸腾后，开启蒸汽阀组件，开口面积开至第一状态，采用直通对流的方式，实现烹饪空间内与外部大气压气体流动，从而实现产生的热量有效流出，避免气泡的产生与溢出。Before the food reaches the boiling temperature, the steam valve assembly remains closed, that is, the opening area is zero. In this way, the rapid escape of water vapor and heat loss can be avoided, the proportion of water can be maintained, the phenomenon of refilling water can be eliminated, and the cooking time can be shortened. After heating to boiling, the steam valve assembly is opened, the opening area is opened to the first state, and the direct convection method is adopted to realize the atmospheric pressure gas flow between the cooking space and the outside, thereby realizing the effective outflow of the generated heat and avoiding the generation and overflow of bubbles.
步骤S3：继续加热第一预设时长后，判断水占比是否大于第一预设值；Step S3: After the heating is continued for the first preset time period, it is determined whether the proportion of water is greater than the first preset value;
步骤S4：若是，扩大蒸汽阀组件开口面积至第二状态；Step S4: If yes, expand the opening area of the steam valve assembly to the second state;
步骤S5：若否，缩小蒸汽阀组件开口面积至第三状态。Step S5: If not, reduce the opening area of the steam valve assembly to the third state.
比较检测到的水占比与第一预设值。当水占比大于第一预设值时，说明水含量较大，则控制步进电机4正转，通过驱动齿轮5、配合齿11、驱动盘9以及驱动轴，驱动叶片结构6绕第一方向正向转动以实现蒸汽阀组件开口面积的增大。扩大蒸汽阀组件开口面积至第二状态，以实现将水蒸气快速排出从而加快水占比的变化速度。Compare the detected water percentage with the first preset value. When the water ratio is greater than the first preset value, indicating that the water content is large, the stepping motor 4 is controlled to rotate forward. Through the driving gear 5, the matching teeth 11, the driving disk 9 and the driving shaft, the blade structure 6 is driven to rotate around the first The direction is positively rotated to increase the opening area of the steam valve assembly. Enlarge the opening area of the steam valve assembly to the second state, so as to quickly discharge water vapor and accelerate the rate of change of the water ratio.
当水占比小于第一预设值时，说明水含量较小，则控制步进电机4反转，通过驱动齿轮5、配合齿11、驱动盘9以及驱动轴，驱动叶片结构6绕第一方向反向转动以实现蒸汽阀组件开口面积的缩小。缩小蒸汽阀组件开口面积至第二状态，以实现将水蒸气缓慢排出从而降低水占比的变化速度。以煮粥为例，水占比即用来表示米水比例。水占比第一预设值可选的范围为：9/10-11/12。When the water ratio is less than the first preset value, indicating that the water content is small, the stepping motor 4 is controlled to reverse, and the blade structure 6 is driven around the first through the drive gear 5, the matching teeth 11, the drive plate 9 and the drive shaft. The direction is reversed to reduce the opening area of the steam valve assembly. The opening area of the steam valve assembly is reduced to the second state, so as to slowly discharge water vapor to reduce the rate of change of the water ratio. Taking porridge as an example, the proportion of water is used to express the proportion of rice to water. The selectable range of the first preset value of water ratio is: 9/10-11/12.
本实施例中，以上述实施例中蒸汽阀组件一种具体结构描述扩大和缩小开口面积的控制过程。显然，对于其他结构和其他形式的可控面积蒸汽阀，根据上述控制原理控制开口面积的变化也可实现相同的效果。In this embodiment, a specific structure of the steam valve assembly in the above embodiment is used to describe the control process of expanding and reducing the opening area. Obviously, for other structures and other forms of controllable area steam valves, the same effect can be achieved by controlling the change of the opening area according to the above-mentioned control principle.
可选的，步骤S4还包括：Optionally, step S4 further includes:
继续加热时间第二预设时长后，判断水占比是否大于第一预设值；After the heating is continued for the second preset duration, it is determined whether the proportion of water is greater than the first preset value;
若是，蒸汽阀组件维持当前状态；If yes, the steam valve assembly maintains the current state;
若否，缩小蒸汽阀组件开口面积至第三状态。If not, reduce the opening area of the steam valve assembly to the third state.
当水占比大于第一预设值时，扩大蒸汽阀组件开口面积至第二状态后继续加热第二预设时长。而继续加热第二预设时长后，仍不能保证水占比为第一预设值，仍然需要进行判断。继续比较检测到的水占比与第一预设值。此过程可多次循环，直至水占比不大于第一预设值。然后缩小蒸汽阀组件开口面积至第三状态。When the proportion of water is greater than the first preset value, the opening area of the steam valve assembly is expanded to the second state and the heating is continued for the second preset period of time. However, after heating for the second preset time period, the water ratio cannot be guaranteed to be the first preset value, and judgment is still required. Continue to compare the detected water percentage with the first preset value. This process can be circulated multiple times until the proportion of water is not greater than the first preset value. Then reduce the opening area of the steam valve assembly to the third state.
该控制方法可通过判断加热时长或水占比是否满足要求，来控制蒸汽阀的 关闭。即控制过程的结束。This control method can control the closing of the steam valve by judging whether the heating time or the proportion of water meets the requirements. That is the end of the control process.
第二状态、第一状态和第三状态对应蒸汽阀的开口面积应依次减小，优选的，第一状态、第二状态和第三状态分别为蒸汽阀最大开口面积的0.5、0.75和0.25倍。The opening area of the second state, the first state and the third state corresponding to the steam valve should be reduced in sequence. Preferably, the first state, the second state and the third state are respectively 0.5, 0.75 and 0.25 times the maximum opening area of the steam valve .
通过上述描述可知，本申请提供的控制方法通过检测温度、水占比与工作时间的方式来调节蒸汽阀的开口面积；在沸腾前的加热阶段，关闭蒸汽阀，避免热量散失与水蒸气排出，保证加热效率与水占比，缩短蒸煮时间当到达沸腾温度后，蒸汽阀开启，采用直通对流的方式，实现烹饪空间内与外部大气压气体流动，从而实现产生的热量有效流出，避免气泡的产生与溢出；从而可适应大功率蒸煮。随后根据水占比自动调整蒸汽阀开口面积，在避免气泡的产生与溢出的同时，还避免热量快速散失以及水蒸气快速逃逸，解决了蒸汽阀开口面积与加热功率的矛盾关系，提高加热效率与用户使用体验。It can be seen from the above description that the control method provided in this application adjusts the opening area of the steam valve by detecting temperature, water ratio and working time; in the heating stage before boiling, the steam valve is closed to avoid heat loss and water vapor discharge. Ensure the heating efficiency and the proportion of water, shorten the cooking time. When the boiling temperature is reached, the steam valve opens, and the direct convection method is adopted to realize the air flow between the cooking space and the outside atmospheric pressure, so as to realize the effective outflow of the generated heat and avoid the generation of bubbles. Overflow; so as to adapt to high-power cooking. Subsequently, the opening area of the steam valve is automatically adjusted according to the proportion of water. While avoiding the generation and overflow of bubbles, it also avoids rapid heat loss and rapid escape of water vapor, solving the contradiction between the opening area of the steam valve and heating power, and improving heating efficiency and User experience.
可选的，在本申请的一些实施例中，该控制方法还包括：Optionally, in some embodiments of the present application, the control method further includes:
采用第一预设功率加热至沸腾温度；Use the first preset power to heat to the boiling temperature;
继续加热第一预设时长后，采用第二预设功率加热；After continuing to heat for the first preset time period, use the second preset power for heating;
第一预设功率大于第二预设功率。The first preset power is greater than the second preset power.
如此设置，在加热至沸腾的过程中采用大功率大火力加热，保证加热速度，缩短烹饪时间以提高用户体验。而当沸腾后采用较小功率加热，避免水蒸气的快速逃逸，从而杜绝二次加水的情况。With such a setting, high-power and high-fire power heating is used during the heating to boiling process to ensure the heating speed and shorten the cooking time to improve the user experience. When it boils, it is heated with a lower power to avoid the rapid escape of water vapor, so as to prevent the situation of refilling water.
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本申请创造的保护范围之中。Obviously, the foregoing embodiments are merely examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, other changes or modifications in different forms can be made on the basis of the above description. It is unnecessary and impossible to list all the implementation methods here. The obvious changes or changes derived from this are still within the scope of protection created by this application.
