Embodiment Construction

[0026] figure 1The flash heater D shown is, for example, a so-called shower heater SH for heating shower water, the main part of which is a heating module H consisting of a plastic injection molded part, of which an upper molded part 1 is visible. The heating module H delimits an internal flow-through channel 2 in which an electric heating body system K is installed. In the embodiment shown, there are two heating body systems K1 and K2 which can be switched on separately in order to obtain three heating power levels (none, one or all heating body systems switched on). It is also possible to provide more than two separately switchable heating body systems. Another configuration has a heating body system or parallel heating body systems for stepless heating power variation between no heating power and maximum heating power, more precisely, for example by means of a power control electronics E Adjust the heating current.

Abstract

In a transient heater (D), the heater has a heating module (H) with at least one heating body system (K, K1, K2), a rotatable adjustment member (L ), at least one fixed electrical switching system (S) and a slider system (A) for operating the switching system (S) that can be linearly adjusted according to the flow, the slider system (A) is rotatable and coupled with the adjustment member (L), in each heating body system a switch system (S) is equipped with only one switch member (3, 4, 3'), and the slider system (A) is constituted as follows : The corresponding heating power can be preselected only by adjusting the rotational position of the slider system (A) relative to the switch system (S), and the heating power can be invoked through the linear adjustment of the slider system.

Description

technical field [0001] The invention relates to a flash heater. Background technique [0002] In a known instantaneous heater used in practice, in the case of two separately activatable heating bodies, two switching elements are provided for calling up a preselected heating power depending on the flow, which are controlled by The slide system is switched on via an actuating membrane activated by the flow. When the operating membrane linearly adjusts the slider system, in the case of two heating bodies, two further microswitches, which can be switched on via switching cams depending on the rotational position, are connected in series, for example, to the rotatable heating power preselection. in front of the adjusting member, since such a switching member is respectively switched independently of the rotational position of the slide system. That is to say, each switching element switched on by the actuating membrane receives current only when its associated microswitch is sw...
