Abstract
The utility model discloses a control circuit for a linked switch of a household central air conditioner. The utility model is composed of an original control circuit of a host machine of an air conditioner, and a new control circuit which is additionally arranged at the utility model. Two parts of the circuits are connected and converted with each other by a converting switch QT, and the converting switch is concentrated on the control circuit of the original host machine when the converting switch selects the centralized control; so the air conditioner can be started by the converting switch and a starting button which is arranged on a panel, and each room can not control the host machine of the air conditioner. The air conditioner can be dispersively controlled by each room when the converting switch selects the dispersive remote control. The momentary connection can be realized when the utility model is used, so a protective circuit of the original control circuit can be guaranteed to do action such as the automatic stop of the air conditioner can be realized when the overvoltage and the over temperature happen, etc; thus, the host machine of the air conditioner can be started as long as the power of one guest room is switched on, and the host machine of the air conditioner can be automatically stopped when the power of all guest rooms is switched off.
Description
The utility model relates to a kind of switch control road.
The residential central air conditioning opening process is generally, open the switch of the outer unit of priming chamber earlier, the three speed switch of opening chamber's inner blower coil pipe again, when closing, even all indoor three speed switch are closed, off-premises station is still worked, again unit gauge tap outside the close chamber, unit could be out of service, very inconvenient.
The purpose of this utility model provides the central air-conditioning linked switch control road that a kind of each indoor fan switch can the main control system start or stop.
In order to reach above purpose, the utility model central air-conditioning linked switch control circuit is made of the former control circuit of air-conditioner host, newly-increased control circuit two parts, two parts circuit connects conversion by a change-over switch, when change-over switch is selected centralized Control, turn to the original host control circuit, can start air conditioner by the start button on panel, air-conditioner host can not be controlled in each room, when change-over switch is selected to disperse to shake control, when any one indoor fan three speed switch is connected, just enabling signal can be passed the start end of the former control circuit of souvenir, make outdoor host-initiated; Each chamber three speed switch is all closed down, the air-conditioner host autostop.
This circuit plays momentary connection, has guaranteed that protection circuit works in the former control circuit, and as the over-pressure over-temperature autostop etc., as long as a guest room start is arranged, air-conditioner host just can start, when all closing, and the air-conditioner host autostop.
Below in conjunction with specific embodiment the utility model is described further.
Fig. 1 is the circuit structure diagram of utility model.
Residential central air conditioning linked switch control circuit shown in Figure 1 is made of the former control circuit of air-conditioner host, newly-increased control circuit two parts, when change-over switch QT turns to original host control circuit 5, and former control circuit work, air-conditioner host can not be controlled in each room; When change-over switch select to disperse to shake control 14, each indoor fan three speed switch QK sealed in control loop, when a switch connection is wherein arranged, and first auxiliary reclay KA
