Example IV
A kind of control method of heat-pump-type dish-washing machine, heat-pump-type dish-washing machine include that detection device, control device and heat pump follow
Loop system, which is characterized in that the temperature control heat pump circulating system for the washing water that control device is detected according to detection device is to washing
Wash the heating speed of water.
At heating initial stage, the heating efficiency of heat pump circulating system is high, and the temperature ramp-up rate of washing water is fast, and energy consumption is high, energy
Enough be rapidly achieved target temperature, it is premature to be heated to target temperature if the washing stage long operational time, remaining time compared with
Long, heat loss is larger, it is easy to cause the washing later period to be unable to satisfy wash temperature demand, therefore, pass through detection washing water
Temperature, control device, to the heating speed of washing water, make it and wash according to the temperature of washing water adjusting heat pump circulatory system of detection
The temperature for washing water is adapted, and realizes the preferable purpose for reducing energy consumption.
The control method of the present embodiment also can be applied in the heat pump dish-washing machine of one-embodiment of embodiment three, wash
Stage and/or rinse stage, the temperature control heat pump circulating system for the washing water that control device is detected according to detection device is to washing
Wash the heating speed of water, naturally it is also possible to individually control dish-washing machine.
Further scheme, in washing stage and/or rinse stage, control device is default to change heat pump circulating system heating
The preset value of speed, the temperature for the washing water that control device is detected according to detection device and the size relation of preset value, control heat
Pump circulation system changes the heating speed to washing water.
By the way that preset value is arranged, at least two heating periods, the heating speed of different heating periods will be divided into the washing stage
Degree is different, and the energy consumption of heat-pump-type dish-washing machine is reduced by the heating method being gradually heated up.
Further scheme, heat pump circulating system include compressor, and the compressor is speed variable and/or variable power
Compressor, the default preset value for changing compressor rotary speed and/or power of control device, control device detects according to detection device
Washing water temperature and preset value size relation, control compressor converted variable speed and/or power, realize and change heat pump cycle
Heating speed of the system to washing water.
By detection device detect washing water temperature and preset value size relation, adjust compressor revolving speed and/
Or power, control heat pump circulating system is realized to the heating speed of washing water, and controllability is more preferable, is more convenient for realizing.
Scheme one, the preset value are preset temperature value, the temperature for the washing water that control device is detected according to detection device
The size relation of degree and preset temperature value, controls compressor converted variable speed and/or power.
Further, control device presets the temperature value of washing water, and detection device detects the temperature of washing water, control device
Judge whether the temperature of the washing water of detection is greater than the temperature value of preset washing water, if it is, improving the revolving speed of compressor.
When the temperature of washing water is lower, the revolving speed of compressor is smaller, can meet demand for heat, is greater than in temperature preset
When temperature value, former revolving speed likely results in that heating speed is slack-off, passes through the revolving speed for improving compressor, improves heating speed, meets
Demand for heat.
Further, dish-washing machine starts, and compressor is run with the first revolving speed, and detection device detects the temperature T of washing water, control
Device processed judges whether the temperature T of the washing water of detection device detection is greater than the temperature value T0 of preset washing water, if it is,
Control compressor is run with the second revolving speed, and first revolving speed is less than the second revolving speed.
It after dish-washing machine starting, i.e., is run with the first revolving speed of setting, the revolving speed is smaller, reaches T0 in temperature of washing water, turns
Speed is promoted to the second revolving speed, improves heating speed, meets demand for heat.
Preset temperature value is preferably 40 DEG C.

Then continue with the operation of the first revolving speed；
S4 control device judges whether the temperature of washing water reaches target water temperature, if it is, terminate, if it is not, then after
It is continuous to be run with the second revolving speed.
Scheme two, the preset value are preset rate of temperature change, the washing water that control device is detected according to detection device
Temperature computation washing water rate of temperature change, control device is according to the rate of temperature change and preset rate of temperature change of washing water
Size relation, control compressor converted variable speed and/or power.
If the too low or ambient temperature that the revolving speed of compressor is arranged is too low, the temperature that may result in washing water exists
In considerable time, it is still unable to reach preset temperature.Therefore, by calculating the rate of temperature change of washing water, become according to temperature
The relationship of rate and preset rate of temperature change changes the revolving speed and/or power of compressor, realizes before meeting heating requirements
It puts, reduces the purpose of energy consumption, it is more accurate to control.
Further scheme, control device preset the rate of temperature change △ v of washing water, and control device is examined according to detection device
The temperature value for the adjacent washing water twice surveyed calculates the rate of temperature change △ v ' of washing water, and whether judges rate of temperature change △ v '
Less than preset rate of temperature change △ v, if it is, improving the revolving speed of compressor.
Further scheme, at interval of the temperature of time t detection once washing water, control device calculates adjacent detection device
The temperature difference △ T of washing water twice calculates rate of temperature change △ v '=△ T/t of washing water,
Control device judges whether rate of temperature change △ v ' is less than preset rate of temperature change △ v, if it is, control pressure
Contracting machine increases revolving speed.
Further scheme, dish-washing machine starting, compressor are run with the first revolving speed, and detection device is detected at interval of time t
The temperature of once washing water, control device calculate the temperature difference △ T of adjacent washing water twice, calculate the rate of temperature change of washing water
△ v '=△ T/t, control device judge whether rate of temperature change △ v ' is less than the rate of temperature change △ v of preset washing water, such as
Fruit is then to control compressor to run with the second revolving speed, and first revolving speed is less than the second revolving speed.
Further scheme, heat-pump-type dish-washing machine open after, compressor first with third revolving speed operation, after a certain period of time again with
The operation of first revolving speed, the first revolving speed of the third revolving speed >.
Compressor first with third revolving speed operation, make lubricating oil oil pump effect under play good lubricating action, later again with
The operation of first revolving speed, extends the service life of compressor.
Preferably, the third revolving speed is at least 6000r/min.
It is explained by taking the washing stage as an example below.
As shown in figure 4, a kind of control method of heat-pump-type dish-washing machine, comprising the following steps:
