Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a discharge operation device for an electric air pot.

[Conventional technology]

In the discharge operation device of the electric air pot,
A steam passage is formed between the inner container and the steam vent;
A steam valve box is provided in the middle of the steam passage, and when a discharge button is operated, the steam valve is actuated to close the steam passage and the electric air pump is turned on.

FIG. 6 shows a discharge operation device that employs a conventionally known means. In this case, the discharge button 1 is supported by a spring 2, and by pressing down the discharge button 1 while keeping it in a parallel state, the discharge button can be pressed. A structure is adopted in which the steam valve 4 of the steam valve box 3 is operated at one end of the steam valve 1, and at the same time, the switch 5 for the electric air pump is operated at the other end.

[Problem that the invention attempts to solve]

If the configuration shown in FIG. 6 is adopted, it is not always possible to press down the ejection button 1 in parallel; for example, if the ejection button 1 is pushed down with a finger hooked to the edge of the ejection button 1, the ejection button 1 As a result, the timing of the operation of the switch 5 and the closing of the steam passage 6 by the steam valve 4 may not coincide with each other. If these timings do not match, for example, the electric air pump will be started even though the steam passage 6 is not completely blocked, resulting in a problem that steam will be ejected from the steam hole of the pot.

On the other hand, if there is a delay in starting the electric air pump, there is a problem in that the timing of discharging hot water is shifted.

Therefore, the object of this invention is to provide a discharge operating device that can match the timing of these operations regardless of which part of the discharge button 1 is pressed.

[Means for solving problems]

In order to solve the above problem, this invention installed a steam valve box in the middle of the steam passage, installed a steam valve in the steam valve box to open and close the steam passage, and installed a steam valve in the discharge button installed above the steam valve. And in a discharge operation device for an electric air pot in which each actuating part of the drive switch of an electric air pump is brought into contact with each other, the discharge button is set at the shoulder body of the pot or a part integral therewith as a fulcrum, and the push-down part is moved at a required distance from the fulcrum. The distance from the fulcrum of the contact part of each operating part of the steam valve and drive switch to the discharge button is set to a size that allows a predetermined operating stroke of the steam valve and drive switch to be obtained, respectively. It is something.

[Effect]

When the push-down part of the discharge button is pressed down with a fingertip, the discharge button tilts about its fulcrum, and at the same time pushes in the actuation part of the steam valve and the actuation part of the drive switch. When the steam valve and the drive switch are depressed by an operating stroke corresponding to the distance from the fulcrum of their respective contact parts, the steam valve closes the steam passage, and at the same time, the drive switch starts energizing.
