Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In embodiments of the present invention, dish-washing machine is to tableware when washing operation is carried out, the washing motor in dish-washing machine according to
Target control rotating speed is operated so that spray arm is heated to tableware shower, and heating tube to the water in dish-washing machine.This
The involved target control rotating speed in place refers to the tachometer value for controlling washing motor to operate set in advance.
What Fig. 1 showed the washing method for heating and controlling of dish-washing machine provided in an embodiment of the present invention realizes flow, in order to just
In explanation, the part related to the embodiment of the present invention is illustrate only, details are as follows：
In step sl, during dish-washing machine carries out washing operation to tableware, the operating current to washing motor enters
Row detection.
In step s 2, the target control rotating speed according to detected operating current and washing motor obtains inflow.
Step S2 is specially：
Inflow is calculated according to relationship below：
Wherein, W is inflow, and its unit is L (liter)；I is operating current, and its unit is mA (milliampere)；S is target control
Rotating speed, its unit is RPM (rev/min).
For dish-washing machine, under conditions of different inflows, operating current and the rotating speed of washing motor are presented as shown in Figure 2
Linear relationship；Under different speed conditions, operating current and the inflow of washing motor are presented linear pass as shown in Figure 3
System.In three curves shown in Fig. 2, the inflow corresponding to curve W1 is minimum, and the inflow corresponding to curve W2 is placed in the middle, bent
Inflow corresponding to line W3 is maximum.And in three curves shown in Fig. 3, the rotating speed corresponding to curve S1 is minimum, curve S2
Corresponding rotating speed is placed in the middle, the rotating speed highest corresponding to curve S3.Above-mentioned relation formula (1) is actually according to Fig. 2 and Fig. 3 institutes
Obtained from the linear relationship shown.
In step s3, when inflow is less than heating institute's water requirement, the heating tube in control dish-washing machine is stopped.
Wherein, heating institute water requirement refers to the inflow needed for heating tube normal work, and it is value set in advance.Due to
Also there is the situation more than or equal to above-mentioned heating institute water requirement in inflow, so, when inflow is not less than heating institute water requirement
When, then do not control the heating tube in dish-washing machine to be stopped, heating tube can continue to heat the water in dish-washing machine.
Fig. 4 shows that the embodiment of the present invention provides the modular structure of the washing heating control apparatus of dish-washing machine, for the ease of
Illustrate, illustrate only the part related to the embodiment of the present invention, details are as follows：
Washing heating control apparatus include：

Detected as electric current；
Inflow acquisition module 200, for the operating current detected by basis and the target control rotating speed of washing motor
Obtain inflow；
Heating tube control module 300, for when inflow is less than heating institute's water requirement, controlling the heating tube in dish-washing machine
It is stopped.
Specifically, inflow acquisition module 200 turns according to the target control of detected operating current and washing motor
The process that speed obtains inflow is specially：
Inflow is calculated according to relationship below：
Wherein, W is inflow, and its unit is L (liter)；I is operating current, and its unit is mA (milliampere)；S is target control
Rotating speed, its unit is RPM (rev/min).
For heating tube control module 300, also there are the feelings more than or equal to above-mentioned heating institute water requirement by inflow
Condition, so, when inflow is not less than heating institute's water requirement, then heating tube control module 300 does not control the heating in dish-washing machine
Pipe is stopped, and heating tube can continue to heat the water in dish-washing machine.
In actual application, heating tube control module 300 can be built in the microcontroller of dish-washing machine, work as inflow
When inflow acquired in acquisition module 200 is less than heating institute's water requirement, by the heating tube in the microprocessor control dish-washing machine
It is stopped, so as to realize that dry combustion method is protected to heating tube.
Based on application advantage of the above-mentioned washing heating control apparatus in dish-washing machine, the embodiment of the present invention additionally provides one kind
Dish-washing machine including above-mentioned washing heating control apparatus.
During the embodiment of the present invention to tableware in dish-washing machine by carrying out washing operation, to the work electricity of washing motor
Stream is detected, and obtains inflow according to the target control rotating speed of detected operating current and washing motor, is entered at this
When water is less than heating institute's water requirement, the heating tube in control dish-washing machine is stopped, so that can be in inflow situation on the low side
Under heating tube is stopped heating, to realize that to heating tube accurate dry combustion method is protected, during this need not using pressure switch or
Related pressure special detection device carries out water level judgement, and then saves the cost of dish-washing machine, and solving prior art cannot
The heating tube to dish-washing machine realizes that dry combustion method is protected exactly, and increased the problem of the cost of dish-washing machine.
