Problems solved by technology

[0005] (3) Since the tripping temperature of the temperature limiter is very close to the normal operating temperature, it may cause false tripping
[0006] (4) Since there are usually more than one heating tube, more than one temperature limiter is needed, which makes the cost very high

Abstract

The invention discloses a steam generation device and aims to provide a steam generation device provided with a water shortage detection device. The water shortage detection device judges precisely, has low cost, quick response and a long service life, and can remind a user to clean heating tubes so as to avoid heating without water. The embodiment of the invention provides the steam generation device which comprises a water distribution valve (1) and the heating tubes (2) which are transparent or partially transparent at the lower part, wherein the lower end of a lower electrode (21) of each heating tube (2) is provided with a light-emitting device (111) and a light sensitive element (121); and light emitted by the light-emitting device (111) is refracted by at least one of the heating tubes (2) and then reaches the light sensitive element (121) without passing through an axle center of the heating tube (2). The invention also discloses a household electric steam box which comprises the steam generation device.

Description

technical field [0001] The invention relates to a steam generating device and a household electric steam box. Background technique [0002] In the prior art, there are various steam generators and household electric steamers. As the applicant applied for on February 12, 2010, the application number is 201010114441.6 [Application name is: [household steamer] Chinese invention patent, this patent is provided with a temperature limiter on the heating tube to detect the heat in the heating tube. Whether there is water, so as to judge whether the heat pipe is dry. If there is no water in the heating pipe at the position where the temperature limiter is set, the temperature at this position will rise, and when the temperature rises to the temperature set by the temperature limiter, the temperature limiter will act to make The control circuit cuts off the heating power supply. But the household steamer disclosed in this patent also has the following deficiencies: [0003] (1) S...
