Description

现有的旋风烤锅、 旋风烤箱等食物烘烤器具通常由食物容器和顶置的 发热管和风扇组成, 如图 1所示。说其特点是成本低, 但由于其采用发热源 顶置的加热方式, 食物的底部很难烘烤变色, 使用中, 用户不得不中途翻 转食物, 不能一次连续完成。  Existing food baking appliances such as whirl boilers and cyclone ovens are usually composed of a food container and an overhead heating tube and a fan, as shown in FIG. It is characterized by low cost, but because of the heating method of using the heat source overhead, the bottom of the food is difficult to bake and discolor. In use, the user has to turn the food in the middle, and cannot be completed continuously.
为了解决食物底部的加热问题, 一般会考虑以下三种方案在食物容器 底部增加发热源。  In order to solve the heating problem at the bottom of the food, the following three options are generally considered to increase the heat source at the bottom of the food container.
第一种方案如图 2所示, 将独立的发热管置于食物容器内侧, 类似油 炸锅、 电烤箱等产品, 其特点是热效率高, 但由于容器中独立的发热管易 受到食物液体的侵蚀, 且发热管需要独立的电气连接, 使用极不方便。  The first scheme is shown in Figure 2. The independent heating tube is placed inside the food container, similar to the fryer, electric oven and other products. It is characterized by high thermal efficiency, but the independent heating tube in the container is susceptible to food liquid. Erosion, and the heating tube requires an independent electrical connection, which is extremely inconvenient to use.
第二种方案如图 3所示, 将发热管镶嵌或焊接在食物容器底部外侧, 由于容器底部有电气连接, 这种方式下食物容器不能直接用水清洗。  The second scheme is shown in Fig. 3. The heating tube is inlaid or welded on the outside of the bottom of the food container. Since the bottom of the container has an electrical connection, the food container cannot be directly washed with water in this manner.
第三种方案如图 4所示, 将食物容器放置于发热体表面, 类似电饭煲 等产品, 但这种方式是由发热源间接烘烤食物, 大量的热能会散发到食物 容器之外, 发热效率低。  The third scheme is shown in Fig. 4. The food container is placed on the surface of the heating element, similar to a rice cooker, etc., but this method is to indirectly bake the food by the heat source, and a large amount of heat energy is emitted outside the food container, and the heat efficiency low.
总之, 上述各种方案在热效率、 可操作性、 安全性、 清洁清洗等诸多 方面都存在不尽人意之处。  In short, the above various solutions have unsatisfactory aspects in terms of thermal efficiency, operability, safety, cleaning and cleaning.
