Plate 3 it is electric, and detect temperature detect switch (TDS) 2 disconnect when control supply control unit 4 turn off so that outdoor unit control panel 3 power off.
It should be noted that the triggering break-off signal of temperature detect switch (TDS) 2 can be carried out according to 11 ignition temperature point of connecting terminal
Setting.Specifically, triggering break-off signal is preferably 55 DEG C to 110 DEG C.
It should be noted that connection terminal module 1, temperature detect switch (TDS) 2, supply control unit 4 and indoor unit control panel 5 can be set
The indoor unit in air-conditioning system is set, outdoor unit control panel 3 and compressor M1 may be provided at the outdoor unit of air-conditioning system.
Specifically, as shown in Figures 2 and 3, the lower section of connecting terminal 11 is arranged in temperature detect switch (TDS) 2, in other words, in connecting terminal
Connecting terminal 11 is arranged in the upper layer of module 1, and temperature detect switch (TDS) 2 is arranged in the lower layer of connecting terminal 11.When connecting terminal 11 occurs
It generates heat at connecting terminal 11 when poor contact, temperature at connecting terminal 11 rises, in the temperature at the connecting terminal 11
The first preset temperature is raised to i.e. close to after 11 ignition temperature point of connecting terminal, triggers 2 tripping of temperature detect switch (TDS), when temperature detect switch (TDS) 2 is disconnected

Switch disconnection can make outdoor unit control panel 3 power off.
The control device 100 on fire prevented of the utility model embodiment is described in detail below with reference to a specific embodiment
Working principle.
Complete machine electric current I by taking frequency-conversion air-conditioning system such as two Split type air conditioners of frequency conversion as an example, when air conditioner operates normally
For 8A, it is assumed that connection terminal module 1 is used in coastal area, aoxidizes terminals due to having salt in the air of coastal area
The case where, resistance R is 0.5 Ω at oxidation, thus when compressor start after, heating power is P=I*I*R=at connecting terminal 11
8A*8A*0.5 Ω=32W (heating power is 32 watts i.e. at connecting terminal 11), and the currently used environment of air conditioner is 30 DEG C, phase
Ying Di, temperature detect switch (TDS) 2 trigger break-off signal and are preset as 65 DEG C, are attracted temperature and are preset as 53 DEG C.
After normally powering on, indoor unit control panel 5 is powered by supply control unit 4 to outdoor unit control panel 3, to control
Compressor M1 operation.Temperature detect switch (TDS) 2 is that room temperature is connected such as 30 DEG C, after indoor unit control panel 5 detects that temperature detect switch (TDS) 2 is closed at this time
Relay 41 is controlled by supply control unit 4 to be attracted, and then power supply is made to be transported to outdoor unit control panel 3, outdoor unit control
Making sheet 3 controls compressor M1 operation, and indoor unit control panel 5 detects that electric current is 8A at this time, and indoor unit control panel 5 determines compressor
M1 starting is normal.
If generated heat at connecting terminal 11 by heating power 32W after compressor M1 is attracted, temperature detect switch (TDS) 2 is increased from 32 DEG C
To 65 DEG C of break-off signal of triggering, temperature detect switch (TDS) 2 is disconnected at this time, and indoor unit control panel 5, which detects to control after temperature detect switch (TDS) 2 disconnects, to be passed through
Supply control unit 4 controls 41 power loss of relay, to make 3 power loss of outdoor unit control panel, i.e. compressor M1 power loss.It is indoor at this time
Machine control panel 5 detects that electric current becomes 0.5A from 8A, can determine that temperature detect switch (TDS) 2 overheats stop jumping.
After first preset time such as 30 seconds 2 minutes, temperature detect switch (TDS) 2 and connecting terminal 11 can drop to 53 from 65 DEG C
DEG C, temperature detect switch (TDS) 2 becomes attracting state from off-state, and indoor unit control panel 5 is attracted the second preset time example in temperature detect switch (TDS) 2
It is attracted again as controlled relay 41 by supply control unit 4 after 3 minutes, outdoor unit control panel 3 obtains electric and controls compressor
M1 operation, indoor unit control panel 5 detect that electric current is 8A.However, due to having contact resistance (i.e. heating power at connecting terminal 11
32W), temperature detect switch (TDS) 2 rises to 65 DEG C of break-off signal again, and power loss is out of service again by compressor M1 as previously described, indoor at this time
Machine control panel 5 detects that electric current is 0.5A, and indoor unit control panel 5 can determine whether to act for temperature detect switch (TDS) 2, and control power supply control list
Member 4 stops power supply.
Since the overheat stop jumping of the temperature detect switch (TDS) 2 in continuous 2 connection terminal modules 1 has occurred, can determine that as terminals
Sub 11 contact resistances are excessive, and indoor unit control panel 5 controls air-conditioning system shutdown to enter guard mode of shutting down, and passes through display
The output display of unit 6 fault code such as " P6 ", to remind user to overhaul air conditioner.
To sum up, the air-conditioning system proposed according to the utility model embodiment prevents that control device on fire, temperature detect switch (TDS) are connecing
The temperature of line end submodule middle connecting terminal disconnects when being greater than the first preset temperature, and control supplies when detecting temperature detect switch (TDS) and disconnecting
Electric control unit turns off so that outdoor unit control panel powers off, and machine control panel detects control when temperature detect switch (TDS) is connected indoors
Supply control unit be connected so that outdoor unit control panel obtain it is electric.Power supply control is controlled when detecting that temperature detect switch (TDS) disconnects as a result,
Unit turns off so that outdoor unit control panel powers off, to prevent wiring caused by connecting terminal temperature anomaly from burning out or on fire hidden
Suffer from, promotes the safety of air conditioner.
