Embodiment Construction

[0019] First please refer to figure 2 As shown, a microwave oven 100 according to an embodiment of the present invention includes a microcontroller 102 , a temperature detecting device 104 , a water supply device 106 , a steam heater 108 and a microwave generating device 110 . The temperature detection device 104 is, for example, set in a steam generating tank (not shown), so as to detect the temperature in the tank immediately. The water supply device 106 is used to provide water for evaporation to the steam generating tank. The steam heater 108 is used for heating the water in the steam generating tank, and the microwave generating device 110 is used for emitting microwaves to heat the food in the microwave oven 100 .

[0020] refer to image 3 and combine figure 2 As shown, the water supply control method for a microwave oven according to an embodiment of the present invention includes the following steps:

[0021] In step 200, the microwave oven 100 starts cooking ac...

Abstract

The invention relates to a water-feeding control method of a steam microwave oven, wherein the steam microwave oven comprises a steam generation tank, a water feeding device, a steam heater and a microwave generator; the method comprises the following steps: firstly, the cooking is carried out according to the time setting of a user; secondly, the temperature in the steam generation tank is detected and compared with a critical value; thirdly, when the detected temperature reaches the critical value, the remain cooking time is compared with an average water feeing period, wherein the water feeding device feeds water to the steam generation tank according to a normal water feeding quantity and continuously the temperature in the steam generation tank is detected when the remain cooking timeis more than or equal to the average water feeing period; and the water feeding device feeds water to the steam generation tank according to an adjusted water feeding quantity when the remain cookingtime is less than the average water feeding period.

Description

technical field [0001] The invention relates to a steam microwave oven, in particular to a water supply control method for the steam microwave oven. Background technique [0002] Steam microwave ovens rely on water evaporation to form steam to assist microwaves in heating food. Whenever the temperature rises to the critical point, the water in the steam generating tank is basically used up, and water needs to be fed. figure 1 It is the water supply control process of the existing steam microwave oven. The water supply of the steam microwave oven is simply based on the temperature detection value each time. The water supply in the water supply cycle t2 is t1. For this prior art, since the remaining cooking time is not considered, the original water supply is also maintained when the cooking is about to end (such as remaining cooking time t0<t2). In this way, there is a part of excess water in the steam generating tank in the chamber when the cooking is finished; even at...
