Title:
CONTROL SYSTEM FOR BATHTUB RELATED EQUIPMENT
Document Type and Number:
Japanese Patent JP3522979
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the cost by decreasing the number of parts by unifying substrates or control panels, of which the main function is equal, by providing a means for discriminating the presence/absence of optional function of equipment, of which the main function is equal, and a means for judging whether or not the operation of that optional function is to be accepted.
SOLUTION: The presence/absence of a filtering function as the optional function of an air bubble generator is judged by an optional function presence/ absence discriminating means 31. First of all, it is watched whether a three-way valve position signal is detected or not. In case of YES, the permission of filtering function (the presence of a filter) is judged. In case of NO, on the other hand, a three-way valve is driven and the position signal of the operated three-way valve is waited for prescribed time. When no signal is detected within the prescribed time, the inhibition of filtering function (the absence of the filter) is judged. This discriminated result is sent to an acceptance judging means 32, and the acceptance judging means 32 regulates a manipulating means 33 or an operating means 34. Namely, based on the presence/absence or permission/ inhibition judgement of the optional function, the operating switch of the manipulating means 33 is to be accepted or not to be accepted.
