Abstract
The utility model relates to a temperature control three-speed switch of a subminiature fan coil pipe, belonging to a product in the technical field of an air conditioner. The temperature control three-speed switch of a subminiature fan coil pipe is composed of a four-position three-speed switch, a thermosensitive element, a voltage comparator, and a relay. The temperature control three-speed switch of a subminiature fan coil pipe can control the high speed, the medium speed, and the low speed of a fan, and the temperature control three-speed switch of a subminiature fan coil pipe can control the stop and the opening of the fan and the opening and the closing of an electric water valve according to the requirements of environment temperature.
Description
The utility model relates to the control of three kinds of rotating speeds of air conditioner with blower and coiled tube and utilizes variation of ambient temperature control blower motor to stop, open switching with the water route.
The hotel generally adopts air conditioner with blower and coiled tube at present, but and its supporting temperature detect switch (TDS), all exist the defective that some use, the temperature detect switch (TDS) that reveals the palace as Japan has only a kind of rotating speed control, the utility model patent of China: though 85203171.8 room thermostats have increased a kind of rotating speed control, but still can not satisfy three speed control system requirements, particularly sensitivity is higher, fan coil opens, stops undue frequent, and volume is generally bigger, in the mounting box of the standard of can not packing into.
The purpose of this utility model provides a kind of three kinds of speed of fan coil of can controlling and can stop, open and the switching in water route according to the requirement of environment temperature control blower fan again, also in circuit, added a time delay process in addition, overcome blower fan and stopped, open frequent defective.Simultaneously in also little, the standard of can packing into the mounting box of volume.
The purpose of this utility model is to realize like this.
As shown in Figure 1, major loop is realized stopping and high, medium and low three speed by four toggle switch k1.When pushing high, medium and low arbitrary position, all can connect the temperature control circuit by switch.Below further analysis how to utilize the break-make of environment temperature pilot relay J.

This circuit carries out test of many times, and is respond well.
Among Fig. 2,1 is thermoregulation knob, and 2 is winter, summer switch, and 3 for blower fan stops, four gauge tap of high, medium and low three speed, and 4 is pilot lamp.
Claims (2)
1, a kind of fan coil temperature control three speed switch has the direct dialing type four way switch; Thermoregulation knob, winter, summer switch, pilot lamp is characterized in that having a thermistor, resistance, bridge-type temperature-sensitive link and resistance that potentiometer is formed, electric capacity, the time delay process that voltage comparator is formed;
2, fan coil temperature control three speed switch as claimed in claim 1 is characterized in that using in the control circuit capacitor C
