To 200 side of pad portion.
The control unit 170 controls the heating temperature generated heat from heater 111, so as to examine from the first temperature sensor 140
The water temperature measured and it can reach each for being separated in pad portion 200 from the water temperature that second temperature sensor 160 detects
A region and the target temperature set.
In Fig. 3, not specifying symbol 104 indicates power supply line, and in Fig. 4, and undeclared symbol 181 indicates that conduction is opened
It closes, for cutting off the power when boiler portion 100 is overturned to side;182 indicate overcurrent fuse, for when applying overcurrent
Block the supply of power supply;183 indicate frost prevention switch.
In addition, the hot water mat includes function configuration part (not shown), for setting sterilizing function mode.If user exists
Function configuration part selects sterilizing function mode, then control unit 170 will be to have in the temperature sensor 115 in sink portion 110
On the basis of detected temperature, and the driving of the heater 111 and water pump 120 is controlled, thereby executing one for sterilizing
Series of steps.
Hereinafter, being illustrated referring to Fig. 5 to the sterilizing methods of hot water mat of the invention.
The sterilizing methods of hot water mat of the invention include the following steps: that user selects sterilizing function mode (S1);Driving institute
State heater 111, and the driving (S2) of middle water cut-off pump 120;In the sink portion 110 that the temperature sensor 115 is sensed
Water temperature and the first preset temperature be compared (S3);If it is default that the water temperature in the sink portion 110 rises to described first
More than temperature, then water pump 120 (S4) is driven in the state of maintaining the driving of heater 111;By 115 institute of temperature sensor
The water temperature in sink portion 110 and the second preset temperature table sensed is compared (S5);If the water in the sink portion 110
Temperature drop to second preset temperature hereinafter, then in the state of keeping the driving of heater 111 middle water cut-off pump 120 driving
(S6);And the step of executing (S3) to (S6) repeatedly within a preset time.
In the case, first preset temperature can be set within the scope of 75 DEG C~80 DEG C that sterilizing can be achieved
Temperature;Second preset temperature can be set to the temperature within the scope of 65 DEG C~70 DEG C.
In addition, the preset time can be set to the hot water for indicating to be built in pad portion 200 in (S7) step
Time in a period of flow more than water capacity in pipe is heated in the heater 111 in the sink portion 110 and is recycled.
It is intended that making in the enough all recycling screw clamp portions 110 of the water energy in the hot-water line recycled in pad portion 200 to sterilize
Processing.
As described above, in the present invention, when selecting sterilizing function mode, executing following operation: to prevent from storing
Heater 111 is driven in the state of the driving of middle water cut-off pump 120 in the flowing of the water in sink portion 110, and is heated water to
First preset temperature, to carry out sterilization treatment to bacterium included in the water being stored in sink portion 110, and primary
After sterilisation process terminates, restore the driving of water pump 120, it will be in the water recycling screw clamp portion 110 in pad portion 200
Portion.
In the process, it is recycled in sink portion 110 with dampening, the water temperature in sink portion 110 will therewith and gradually
Ground reduces, and if being down to the second preset temperature, the middle water cut-off pump 120 in the state of maintaining the driving of heater 111
Driving heats the water in sink portion 110 and reaches the first preset temperature to block the flowing of water, thereby executing
Two-stage sterilization processing.
If executing above-mentioned step repeatedly during preset time, can be with the short time in sink portion 110
Unit and the sterilization treatment for executing the heating by water rapidly, also, if executed at sterilizing repeatedly during preset time
Reason, then can execute sterilization treatment in the whole region of hot water mat.
In addition, during executing sterilizing function, the water for the high temperature for being heated and supplying by means of heater 111 and
It is enough mixed with each other in the hot-water line for being built in pad portion 200 one by the water energy that is in relative low temperature state of the product in hot-water line
It rises, therefore, the hot-water line in pad portion 200 can maintain within the scope of the not temperature of the safety of burn hazard.
As described above, the present invention have the advantages that it is as follows: completely use existing hot water mat mechanical structure it is same
When, in the state of maintaining the driving of heater 111, by the temperature detected by temperature sensor 115 and the first default temperature
Degree and the second preset temperature are compared, hereby it is possible to easily by the driving condition that controls water pump 120 restrictively
It executes to the sterilization treatment comprising bacterium in water, therefore, is able to suppress infrequently replacement is used for the water of hot water mat
The breeding of bacterium, so as to safely and conveniently use hot water mat.
