Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present application is described in conjunction with a washing machine, the technical solution of the present invention is not limited thereto, and the door opening control method can be obviously applied to other laundry treating apparatuses such as a clothes dryer, a shoe washer, a washing and drying machine, etc., without departing from the principle and scope of the present invention.
Based on the technical problems provided in the background art, the invention provides a door opening control method for a washing machine, which aims to selectively enable the washing machine to execute door opening operation according to the detection result of whether a high heat source and a low heat source exist on a user entering a preset range at the same time, so that the aim of automatically opening a door body of the washing machine is fulfilled.
Referring to fig. 1 and 2, fig. 1 is a flowchart of a door opening control method of the present invention; fig. 2 is a flowchart of a door opening control method according to an embodiment of the present invention. As shown in fig. 1, the door opening control method of the present invention includes the steps of:
s1, detecting whether a user enters a preset range near the washing machine or not;
s2, selectively detecting whether a high heat source and a low heat source exist on the user body at the same time according to the detection result of whether the user enters the preset range;
and S3, selectively enabling the washing machine to execute door opening operation according to the detection result of whether the high heat source and the low heat source exist on the user body at the same time.
Preferably, before the washing machine is operated, the laundry needs to be washed, or during the operation of the washing machine, there may be a case where the laundry is added halfway, and therefore, before or during the operation of the washing machine, step S1 is performed to detect whether a user enters a preset range.
In a preferred embodiment, in step S2, the step of selectively detecting whether there are both high heat source and low heat source on the user according to the detection result of whether there is a user entering the preset range includes:
s21, if a user enters a preset range, detecting whether a high heat source and a low heat source exist on the user at the same time;
and S22, if no user enters the preset range, not detecting whether a high heat source and a low heat source exist on the user at the same time.
In step S21, if the user enters the preset range, which indicates that the user may want to operate the washing machine to wash the laundry or may want to wash the laundry without operating the washing machine through the washing machine, in order to accurately determine whether the door of the washing machine is to be opened so that the user can wash the laundry using the washing machine, whether the high heat source and the low heat source are simultaneously present on the user is further detected, and the door opening operation of the washing machine is selectively performed according to the detection result of whether the high heat source and the low heat source are simultaneously present on the user.
In step S22, if no user enters the preset range, which indicates that no user wants to operate the washing machine to wash the laundry, and the user outside the preset range does not operate the washing machine to wash the laundry, the method does not detect whether the user has both a high heat source and a low heat source, and returns to step S1 to detect whether the user enters the preset range again.
In the above process, by setting the preset range, it can be concluded whether to perform an operation of detecting whether the high heat source and the low heat source are simultaneously present on the user. The preset range is the maximum range (for example, the range with the radius of 1.5 m) in which the user can be determined to operate the washing machine, or the maximum range in which the user can be accurately detected by a radar detector, an infrared sensor, and the like, and the preset range is not limited to the above-mentioned range, and those skilled in the art can flexibly adjust and set the preset range according to actual situations as long as the boundary point determined by the preset range can meet the requirement of determining whether to perform the operation of detecting whether the user has a high heat source and a low heat source at the same time.
Preferably, the washing machine includes an infrared sensor; in step S21, the step of "detecting whether a high heat source and a low heat source exist on the user at the same time" includes:
s211, detecting whether a high heat source and a low heat source exist on the user body at the same time through an infrared sensor.
It will be appreciated by those skilled in the art that the technical means for detecting the presence of both high and low heat sources on the user is not limited to infrared technology, and that other heat source detection methods as will occur to those skilled in the art may be used to detect the presence of both high and low heat sources on the user. It should be further noted that the method for detecting whether the high heat source and the low heat source exist on the user at the same time should not limit the present invention.
In a preferred embodiment, the step of "selectively enabling the washing machine to perform the door opening operation according to the detection result of whether the high heat source and the low heat source exist on the user at the same time" in the step S3 specifically includes:
s31, if the user has a high heat source and a low heat source, judging whether to make the washing machine execute door opening operation according to the quantity of the low heat source;
and S32, if the high heat source and the low heat source do not exist on the user at the same time, making the washing machine not perform the door opening operation.
The high heat source is a heat source larger than or equal to a human body heat source, the low heat source is a heat source smaller than the human body heat source, and the human body heat source is larger than a clothes heat source which is not worn on the human body, so that the detected heat source is divided into the high heat source and the low heat source through the human body heat source, and whether a user carries clothes to be cleaned or not can be judged. Of course, the division of the high heat source and the low heat source is not limited to the above-mentioned method, and the high heat source and the low heat source may be divided according to experiments or experiences of those skilled in the art under specific conditions, and whatever division method is adopted, the method only needs to meet the requirement of judging whether the user carries the clothes to be cleaned.
In step S31, if the user has both a high heat source and a low heat source, which indicates that the user has other heat sources lower than the self heat source besides the self heat source, and the user is about to operate the washing machine to wash the laundry because the user has entered a preset range, the user may consider that the other heat sources carried by the user are the laundry to be washed, but if only a small number of laundry, such as one or two laundry, is to be washed, the user may perform hand washing without washing the laundry in order to save resources, and in order to accurately determine whether to open the door of the washing machine so that the user can wash the laundry using the washing machine, it is determined whether to open the door of the washing machine according to the number of the low heat sources.
In step S32, if there is no high heat source and no low heat source on the user, it indicates that there is no other heat source except the self heat source on the user, it may be considered that the user does not carry the laundry to be cleaned, and no laundry needs to be cleaned, and even if there is a user entering the preset range, the door of the washing machine does not need to be opened, and the method returns to step S1, and detects again whether there is a user entering the preset range. By adopting the scheme, the washing machine can accurately judge whether to execute door opening operation, the intelligent degree of the washing machine is improved, and the use experience of a user is further improved.
Preferably, the step of "determining whether to cause the washing machine to perform the door opening operation according to the number of the low heat sources" in the step S31 specifically includes:

s312, if the number is larger than or equal to the preset number threshold, enabling the washing machine to execute door opening operation;
and S313, if the number is smaller than the preset number threshold, the washing machine is not executed with the door opening operation.
In step S312, if the number is greater than or equal to the preset number threshold, which indicates that the number of the laundry carried by the user is large, it may be considered that the user will use the washing machine to wash the laundry, so that the washing machine performs the door opening operation, so that the user can put the laundry into the washing tub of the washing machine.
In step S313, if the number is smaller than the preset number threshold, it is indicated that the number of the laundry items to be washed carried by the user is small (for example, one laundry item or two laundry items), and if the laundry machine is used for washing, water resources and electricity resources are wasted, which is not beneficial to saving resources and protecting the environment, it can be considered that the user wants to wash the laundry items by hand or not to wash the laundry items, but does not use the laundry machine for washing the laundry items, the laundry machine does not perform the door opening operation, and the step S1 is returned to detect whether the user enters the preset range again.
In the above process, through setting the preset number threshold, a conclusion that whether the washing machine performs the door opening operation can be given. The preset number threshold is the minimum number (e.g., 3, 4, 5, 6, etc.) capable of determining that the washing machine performs the door opening operation, and may also be an experimental number obtained by a person skilled in the art according to an experiment under a specific working condition, of course, the preset number threshold is not limited to the above-mentioned number, and the person skilled in the art can flexibly adjust and set the threshold according to the actual situation as long as the boundary point determined by the preset number threshold can meet the requirement of determining whether the washing machine performs the door opening operation.
