Problems solved by technology

[0007] Those skilled in the art know that scale will not only cause sanitary hazards, but also make cleaning very inconvenient. More importantly, scale will affect the heating performance of the heater and increase energy consumption. Therefore, how to prevent the generation of scale remains to be solved. a technical issue of

Embodiment approach 1

[0052] The first embodiment of the present invention provides a boiler-type steam heater of a food cooking machine and its anti-scaling treatment method, see figure 1 Shown, boiler-type steam heaters include:

[0053] Boiler chamber 1 can store water for heat treatment of treated objects.

[0054] The heater 2 is arranged inside or outside the boiler cavity 1, and heats the water in the boiler cavity 1 to form steam for heat treatment.

[0055] The water pump 3 can pump water into the boiler cavity 1 .

[0056] The drainer 4 communicates with the boiler cavity 1, and when the water pump 3 pumps water into the boiler cavity 1, the drainer 4 discharges the heated water.

[0057] As a typical arrangement of the components of the food cooking machine, in this embodiment, the boiler-type steam heater is arranged in the food cooking machine. Of course, it can also be set in other necessary equipment.

[0058] The heater 2, the drainer 4 and the water pump 3 are all communicative...

Embodiment approach 2

[0073] The second embodiment of the present invention provides an anti-scaling treatment method, the second embodiment is a further improvement of the anti-scaling treatment method of the first embodiment, the main improvement is that in the second embodiment of the present invention, the heating step, see image 3 As shown, the following sub-steps are also included:

[0074] Detect the heating state of heater 2, where:

[0075] When it is detected that the heating time of the heater 2 exceeds the first preset time, the water changing step is entered.

[0076] Wherein, the first preset time can generally be set as the time taken for the water in the boiler cavity 1 to be heated and evaporate 1 / 3 to 2 / 3 of the amount.

[0077] When it is detected that the heating of the heater 2 exceeds the first preset time, it usually means that the accumulative working time of the heater 2 has been longer. At this time, replenishing water in time can effectively prevent scale precipitation...

Embodiment approach 3

[0085] The third embodiment of the present invention provides an anti-scaling treatment method. The third embodiment is different from the second embodiment. The main difference is that in the second embodiment of the present invention, by judging that the heater 2 The heating time is used to control the water changing step; however, in the third embodiment of the present invention, the water changing step is controlled by the water level detected by the water level sensor 5 .

[0086] Therefore, the third embodiment of the present invention also provides a boiler-type steam heater. Same as the aforementioned embodiments, all are arranged in the food cooking machine. The heater 2, drainer 4 and water pump 3 are all communicatively connected with the control module of the food cooking machine. Its improvement is that, see Figure 7 As shown, the boiler cavity 1 is provided with a water level sensor 5, and the water level sensor 5 communicates with the control module.

Abstract

The invention relates to the field of household appliances, and discloses a boiler-type steam heater, a food processor and a scale-preventing treatment method. The boiler-type steam heater comprises aboiler chamber, a heater, a water pump and a water draining device, wherein the boiler chamber can store water so as to heat a treated material; the heater is arranged inside or outside the boiler chamber and heats the water in the boiler chamber so as to form steam for heating treatment; the water pump can pump water into the boiler chamber; the water draining device is communicated with the boiler chamber, and when the water pump pumps the water into the boiler chamber, the water draining device drains the water after the heating treatment. Through adoption of the boiler-type steam heater,scales can be prevented.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to an anti-scale treatment method, a food cooking machine and a boiler-type steam heater using the anti-scale treatment method. Background technique [0002] A microwave oven is a kind of food cooking machine, which is a modern cooking appliance that uses microwaves to heat food. When in use, the water molecules in the food vibrate with the microwaves, and the vibration of the water molecules and the interaction between adjacent molecules make the water temperature faster. As the temperature rises, the temperature of the food also rises rapidly, and the water evaporates due to the temperature rise, making the food dry. In this context, a steam microwave oven that can keep food moisture comes into being. [0003] A steam oven generally includes a cavity and a steam generating device. In the prior art, the steam generating device can generally have two structures, one ...
