Description

智能温控餐桌 技术领域
本发明涉及智能家居领域，具体地，涉及一种智能温控餐桌。
背景技术
在日常家居生活中，由于散热导致饭菜变冷的问题一直困扰着人们的饮食健康，尤其是在寒冷的冬季或者地区，饭菜易冷的问题更为严重。针对这一问题，现有发明创造虽然提出了一些加热保温的方案，但是这些方案的实用性一般，并且加热保温效果也受到限制。在实际应用中，仍有如下两个局限：1、所述方案需要手动控制加热保温，使用不方便，用户体验差；2、所述方案采用全转盘整体加热的方式对饭菜进行加热保温，但是实际上饭菜因样式不同，其适宜的进食温度是不一样的，例如凉菜是低温时口感好，而汤菜是高温时为佳，因此这种方式将会影响部分饭菜的口味，甚至进一步影响人们的身体健康。
针对上述饭菜易冷的问题，需要设计一种新型的智能加热保温餐桌系统，不但可以对饭菜进行有针对性的灵活加热保温，还可以获取饭菜的即时温度信息，并对加热保温方式进行反馈控制，从而使餐桌上的饭菜能够维持适宜的进食温度，确保饭菜口味，具有更好的用户体验。
发明内容

本发明提供了一种智能温控餐桌，包括：餐桌主体；加热板，位于餐桌主体上方并且设置有若干个加热格，每两个加热格中间嵌有加热单元；温度传感器，设置在所述加热板的上部，配置为检测所述加热板的温度；加热控制模块，耦合于所述温度传感器和所述加热板，配置为根据所述温度传感器的检测温度来反馈控制所述加热板的温度。所述餐桌主体可以是但不限于是长方形餐桌或圆形餐桌，一方面，由于位于餐桌主体上方的加热板设有若干个加热格，每个加热格可对对应位置的饭菜进行独立加热保温，因此可对饭菜进行有针对性的灵活保温加热；另一方面，每个加热格的上部设有温度传感器，可即时获取位于加热格上方的饭菜温度信息，并将所述温度信息反馈给加热控制模块，加热控制模块根据所述温度信息对相应的加热器进行加热保温控制，因此可对加热保温方式进行反馈控制。通过前述工作方式，所述智能温控餐桌可使餐桌上的饭菜能够维持适宜的进食温度，确保饭菜口味，具有更好的用户体验。
具体的，所述加热格的上部还设有重量传感器；所述重量传感器连接加 热控制模块。所述重量传感器用于获取对应加热格所承受的即时重量信息，并将所述重量信息反馈给加热控制模块。所述加热控制模块还可以根据所述重量信息判断对应加热格上方是否存在饭菜，以便加热控制模块根据所述温度信息对相应的加热器进行加热保温控制。
具体的，所述加热器包括高导热陶瓷材料层和加热盘丝；所述加热盘丝位于高导热陶瓷材料层的下方，并连接加热控制模块。所述加热盘丝用于将电能转化为热能，所述高导热陶瓷材料层用于对热能进行均匀化处理，使加热格可对饭菜进行均匀加热保温，热能最终传递到指定加热的饭菜中，弥补因散热而损失的热量。
具体的，所述加热格为正方形格或正六边形格。
具体的，所述温度传感器为红外线非接触式温度传感器。所述温度传感器利用红外线测温原理，非接触地获取饭菜的即时温度信息，并将所述温度信息及时反馈给加热控制模块，以便加热控制模块进行反馈控制。

具体的，所述加热器6包括高导热陶瓷材料层6a和加热盘丝6b；所述加热盘丝6b位于高导热陶瓷材料层6a的下方，并连接加热控制模块3。所述加热盘丝6b用于将电能转化为热能，所述高导热陶瓷材料层6a用于对热能进行均匀化处理，使加热格4可对饭菜进行均匀加热保温，热能最终传递到指定加热的饭菜中，弥补因散热而损失的热量。所述加热控制模块3通过控制加热盘丝6b的供能通路的方式(例如关闭/导通供能通路，控制供能通路的输出功率等)控制加热器6的工作模式，在需要加热器6加热保温时，导通加热盘丝6b的供能通路，输出合适的功率，加热盘丝6b将电能转化为热能，通过高导热陶瓷材料层6a的均匀化处理，热能最终传递到指定加热的饭菜中，弥补因散热而损失的热量。
具体的，所述加热格4为正方形格或正六边形格。作为优化的，如图2所示，本实施例中的加热格4为正方形格。
具体的，所述温度传感器5为红外线非接触式温度传感器。所述温度传感器5利用红外线测温原理，非接触地获取饭菜的即时温度信息，并将所述温度信息及时反馈给加热控制模块3，以便加热控制模块3进行反馈控制。
具体的，所述加热板2为钢化玻璃板。所述钢化玻璃板具有耐高温特性，可以防止加热板2因加热温度过高出现物理损伤(例如炸裂或变形等)。
具体的，所述餐桌系统还包括位于餐桌主体1的上方、并水平包围加热板2的低导热板8。所述低导热板8可以是但不限于木板，其导热特性差，用于隔离加热板，防止就餐人员因加热板温度过高而被烫伤。
具体的，所述加热控制模块3设置在加热板2的下方，并连接电源插头9。
本实施例所述描述的智能温控餐桌，不但可以对饭菜进行有针对性的灵活加热保温，还可以获取饭菜的即时温度信息，并对加热保温方式进行反馈控制，从而使餐桌上的饭菜能够维持适宜的进食温度，确保饭菜口味，具有更好的用户体验。
如上所述，可较好的实现本发明。对于本领域的技术人员而言，根据本发明的教导，设计出不同形式的智能温控餐桌并不需要创造性的劳动。在不脱离本发明的原理和精神的情况下对这些实施例进行变化、修改、替换、整合和变型仍落入本发明的保护范围内。
