Description
Technical field
The present invention relates to super bath field, more particularly to one kind can be applicable regular tap and then realize bathroom heater scavenger air with blowing
The electronic interlocking control circuit that function is mutually changed.
Background technology
What the warm type super bath of existing wind was commonly equipped with is that wind warms up two-way single motor, by the rotating of two-way single motor and then
Realize ventilation or wind heating function.But, such super bath must match corresponding interlock switch when dispatching from the factory, the interlocking
Switch is primarily served ensures that blowing function exists simultaneously when the warm shelves of wind are opened, otherwise the super bath can because accumulated heat is excessive scaling loss.
There is DPDT key on current interlock switch, it is powered on the middle position key of its side, it is blowing shelves；On the middle position key of opposite side
It is not charged, it is ventilation shelves；And the electricity of the warm shelves of wind is from the middle position key on blowing shelves.When the blowing shelves connection of the switch, in
There is electricity on the key of position, at this moment blowing is sent warm；Not charged on middle position key when shelves of taking a breath are connected, at this moment the warm shelves of wind cannot start, only
Ventilation ventilation.Therefore, just can guarantee that the super bath of the above-mentioned type will not be because of accumulated heat mistake when wind warms up shelves by above-mentioned interlock switch
Scaling loss, finally realizes the repertoire of the super bath more.
But, have been provided with the power switch consistent with interior decoration style in the family of present most of customers, but this
It is only regular tap on the market to plant switch, does not possess interlock function；Numerous customers are in order to safeguard interior decoration simultaneously
Style it is constant, be unwilling arbitrarily to change above-mentioned interlock switch again, so as to the problem brought be possible open blowing shelves when without
Method normally send warm by blowing, or even ventilatory can be also simultaneously opened sometimes, so usually occurring that motor is burnt out, main frame overheat is burnt
The phenomenons such as damage, cause the product normally to use, and finally have impact on the sales volume of the above-mentioned type super bath.
At present through incomplete statistics, the fault rate produced by above-mentioned reason is more than 70%, therefore to reduce because of customer more
The product repair rate that switch causes is changed, into the focus that current major producers consider.
The content of the invention
The technical problem of regular tap can not be applicable the invention aims to solve above-mentioned super bath product, and then be provided
