Problems solved by technology

[0004] The disadvantage of method 1 is that the amount of clothes and the moisture content of the clothes in actual use are uncertain. The actual drying time may be any time within a period of time, but the expected time given is the same value, resulting in the expected drying time The time (displayed drying time) is seriously inconsistent with the actual drying time
The disadvantage of method 2 is that the motor speed cannot form a strict correspondence with factors such as the amount of clothes and the moisture content of the clothes during dehydration. It also leads to a serious discrepancy between the expected drying time (displayed drying time) and the actual drying time. As a result, when the user comes back, he finds that the clothes have not been dried or have already been dried, and the user experience is poor.

Embodiment 1

[0018] The preferred embodiment discloses a method for judging the drying time of a clothes dryer. Such as figure 1 As shown, in the controller of the clothes dryer, there is a database (that is, a database) that includes at least the corresponding relationship between the temperature change rate in the drum and the drying time; measure and calculate the change rate of the temperature value in the drum during the drying process , query the database according to the change rate of the temperature value, obtain the expected drying time and / or load weight, and display the expected drying time, remaining time and / or load weight.

[0019] During the drying process, the clothes dryer has a constant heating power and a constant air volume, and the temperature rise of the air in the inner cylinder is close to linear from the beginning of heating to the temperature equilibrium. The slope of this linear change differs depending on the amount of laundry. According to this feature, test...

Embodiment 2

[0023] This preferred embodiment discloses a method for judging the drying time of a clothes dryer, the process of which is basically the same as that of the first preferred embodiment. In the controller of the clothes dryer, there is a database including at least the corresponding relationship between the temperature change rate in the drum and the drying time; measure and calculate the change rate of the temperature value in the drum during the drying process, and query the database according to the change rate of the temperature value , to get the expected drying time and / or load weight, to display the expected drying time, remaining time and / or load weight.

[0024] The difference is that the method of obtaining the temperature value change rate L is as follows: a first temperature detection device is installed outside the drum, and a second temperature detection device is installed at the air outlet of the drum; it is measured by the first temperature detection device befo...

Embodiment 3

[0026] This preferred embodiment discloses a method for judging the drying time of a clothes dryer, the process of which is basically the same as that of the first preferred embodiment. In the controller of the clothes dryer, there is a database including at least the corresponding relationship between the temperature change rate in the drum and the drying time; measure and calculate the change rate of the temperature value in the drum during the drying process, and query the database according to the change rate of the temperature value , to get the expected drying time and / or load weight, to display the expected drying time, remaining time and / or load weight.

[0027] The difference is that the method of obtaining the rate of change L of the temperature value is as follows: a first temperature detection device is installed outside the drum, and a second temperature detection device is installed at the outlet of the heater; before the drying process starts, it is measured by t...

Abstract

The invention discloses a method for judging the drying time of a clothes dryer, which belongs to the field of clothes dryer control methods and is designed to solve the problems of large errors in the existing judging methods. The method for judging the drying time of the clothes dryer in the present invention is to store in the controller of the clothes dryer at least a database including the corresponding relationship between the temperature change rate L in the drum and the drying time; The rate of change queries the database to obtain the expected drying time, and displays the expected drying time and / or remaining time. The method for judging the drying time of the clothes dryer according to the present invention queries the database according to the rate of change of the temperature value in the drum during the drying process to obtain and display the expected drying time and / or remaining time, and the prompt time given is more accurate and is different from the actual time. The time error is smaller and the customer experience is better.

Description

technical field [0001] The invention relates to a method for judging the drying time of a clothes dryer. Background technique [0002] A clothes dryer is a household appliance that dries washed clothes. The drying process needs to last for a period of time, and the user may leave to do other things during this time period, and come back to pick up the dried clothes after the expected time arrives. [0003] The existing methods for determining the drying process time or remaining time mainly include two types: 1. Display the expected drying time according to the standard working conditions such as the weight and material of the clothes to be dried; RPM to determine expected drying time. [0004] The disadvantage of method 1 is that the amount of clothes and the moisture content of the clothes in actual use are uncertain. The actual drying time may be any time within a period of time, but the expected time given is the same value, resulting in the expected drying time The t...
