Detailed Description
The application provides a control method and a control device of an air conditioner and the air conditioner, so that the air quality in a toilet is improved, and the life of a user is improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a control method of an air conditioner according to the present disclosure. The control method is executed by a processor in the air conditioner and comprises the following steps:
s101: an odor signal generated by the odor sensor is obtained.
Wherein, the odor sensor is arranged on the wall of the intelligent closestool basin, namely on the inner wall of the intelligent closestool basin.
S102: the odor signal is analyzed to obtain the concentration of the first target gas.
An odor sensor is arranged on the wall of a cavity of the intelligent closestool, and the concentration of first target gas in the cavity of the intelligent closestool is detected through the odor sensor. It will be appreciated that the position of the odour sensor arrangement should be such that: in the non-flushing state, the odor sensor is higher than the liquid level in the basin cavity, so that the concentration of the first target gas in the basin cavity can be accurately detected.
In one embodiment, the first target gas is ammonia. In the process of urination of a user, the ammonia concentration in the basin cavity of the intelligent closestool is greatly improved, and the defecation of the user generally has a process of urination excretion, so that ammonia can be used as first target gas.
In another embodiment, the first target gas comprises ammonia and hydrogen sulfide. In the defecation process of a user, the concentration of hydrogen sulfide in a cavity of the intelligent closestool is greatly improved, so that ammonia gas and hydrogen sulfide can be used as first target gas.
Of course, the first target gas may contain other gases, such as indole, generated by the user's defecation, in addition to ammonia and hydrogen sulfide.
S103: if the concentration of the first target gas rises and the rising amplitude within the first preset time reaches a first value, it is determined that the user is seated in the smart toilet and begins to defecate.
S104: and if the concentration of the first target gas is reduced and the reduction amplitude within the second preset time reaches a second value, determining that the user is out of the seat of the intelligent closestool, and controlling the intelligent closestool to carry out flushing operation.
If the concentration of the first target gas rises and the magnitude of the rise within the first preset time reaches the first value, it indicates that the user is seated in the smart toilet and begins to defecate. After the defecation of the user is finished and the intelligent closestool is unseated, the first target gas gathered in the basin cavity begins to diffuse to the external space, and the concentration of the first target gas begins to decrease. Therefore, after it is determined that the user starts to defecate, if the concentration of the first target gas decreases and the decrease magnitude reaches a second value within a second preset time, which indicates that the user is unseated from the smart toilet, the air conditioner controls the smart toilet to perform a flushing operation.
In implementation, the air conditioner sends a flushing trigger signal to the intelligent closestool, so that the intelligent closestool responds to the flushing trigger signal to perform a flushing operation.
It should be noted that, in the above, it has been described that the first target gas may be one gas or may be a plurality of gases. In the case where the first target gas contains a gas, when the concentration of the gas rises and the magnitude of the rise within a first preset time reaches a first value, the air conditioner determines that the user is seated in the smart toilet and starts to defecate. And then, when the concentration of the gas is reduced and the reduction amplitude within a second preset time reaches a second value, the air conditioner determines that the user is separated from the intelligent closestool and controls the intelligent closestool to carry out flushing operation.
In the case where the first target gas includes a plurality of gases, when the concentration of at least one of the gases rises and the magnitude of the rise within a first preset time reaches a corresponding first value, the air conditioner determines that the user is seated on the smart toilet and starts to defecate. And then, when the concentration of the specified amount (which can be 1 or more) of gas is reduced and the reduction amplitude in a second preset time reaches a corresponding second value, determining that the user is out of the seat of the intelligent closestool, and controlling the intelligent closestool to perform flushing operation by the air conditioner.
The air conditioner can accurately determine whether a user sits on the intelligent closestool and starts to defecate or not by analyzing the concentration of the first target gas in the cavity of the intelligent closestool, and also can accurately determine whether the user finishes defecating and leaves the intelligent closestool. That is to say, the air conditioner can accurately determine the service condition of the intelligent closestool by analyzing the concentration of the first target gas in the cavity of the intelligent closestool, and after determining that the user is out of the seat from the intelligent closestool, the air conditioner controls the intelligent closestool to carry out flushing operation.
The first numerical value, the second numerical value, the first preset time and the second preset time are empirical values set through multiple tests.
The control method of the air conditioner, the concentration of first target gas in a cavity of an intelligent closestool is obtained through an odor sensor, if the concentration of the first target gas rises and the rising amplitude in first preset time reaches a first numerical value, it is determined that a user sits on the intelligent closestool and starts to defecate, and then if the concentration of the first target gas falls and the falling amplitude in second preset time reaches a second numerical value, it is determined that the user leaves the intelligent closestool, and the intelligent closestool is controlled to carry out flushing operation. It can be seen that, among the technical scheme disclosed in this application, the air conditioner can accurately determine intelligent closestool's in-service behavior based on intelligent closestool's the concentration of first target gas in the pelvic cavity to confirm that the user leaves the seat from intelligent closestool, control intelligent closestool and wash by water the operation, through carrying out coordinated control to intelligent closestool, can effectively improve the air quality in the bathroom, promote user's living experience.
Referring to fig. 2, fig. 2 is a flowchart illustrating another control method of an air conditioner according to the present disclosure. The control method is executed by a processor in the air conditioner and comprises the following steps:
s201: an odor signal generated by the odor sensor is obtained.
Wherein, the smell sensor is arranged on the wall of the basin cavity of the intelligent closestool.
S202: the odor signal is analyzed to obtain the concentration of the first target gas.
S203: if the concentration of the first target gas rises and the rising amplitude within the first preset time reaches a first value, it is determined that the user is seated in the smart toilet and begins to defecate.
S204: and if the concentration of the first target gas is reduced and the reduction amplitude within the second preset time reaches a second value, determining that the user is out of the seat of the intelligent closestool, and controlling the intelligent closestool to carry out flushing operation.
S205: under the condition that no person sits on the intelligent closestool, if the concentration of the first target gas reaches a first concentration threshold value, the intelligent closestool is controlled to carry out heating and self-cleaning operations.
For specific implementation of steps S201 to S204, refer to the description in the foregoing, and are not described herein again.
In the case of an unattended intelligent toilet, if the concentration of the first target gas reaches a first concentration threshold, this indicates that the wall of the basin of the intelligent toilet is soiled. For example, after the intelligent toilet completes the flushing operation, the concentration of the first target gas in the bowl cavity is still greater than or equal to the first concentration threshold, or, in the case of no one using the intelligent toilet, the concentration of the first target gas in the bowl cavity is still greater than or equal to the first concentration threshold, which indicates that there is dirt on the bowl wall of the intelligent toilet. In this case, the air conditioner controls the intelligent toilet to perform heating and self-cleaning operations to remove dirt on the wall of the bowl, thereby improving the air quality in the toilet.
In implementation, the air conditioner sends a self-cleaning trigger signal to the intelligent closestool, so that the intelligent closestool responds to the self-cleaning trigger signal to perform heating and self-cleaning operations.
Wherein the first concentration threshold is an empirical value set by a plurality of tests.
In the control method of the air conditioner shown in fig. 2, the concentration of a first target gas in a cavity of an intelligent toilet is obtained through an odor sensor, if the concentration of the first target gas rises and the rising amplitude within a first preset time reaches a first numerical value, it is determined that a user sits on the intelligent toilet and starts to defecate, and then, if the concentration of the first target gas falls and the falling amplitude within a second preset time reaches a second numerical value, it is determined that the user leaves the intelligent toilet and controls the intelligent toilet to perform a flushing operation. It can be seen, among the technical scheme disclosed in this application, the air conditioner is based on the concentration of the first target gas in intelligent closestool's the pelvic cavity, can accurately determine intelligent closestool's in service behavior and sanitary condition, after confirming that the user leaves the seat from intelligent closestool, control intelligent closestool and wash by water the operation, when confirming intelligent closestool's pelvic cavity wall has the dirt, control intelligent closestool and heat and automatically cleaning operation, through carrying out coordinated control to intelligent closestool, can effectively improve the air quality in the bathroom, promote user's experience of living.
Referring to fig. 3, fig. 3 is a flowchart illustrating another control method of an air conditioner according to the present disclosure. The control method is executed by a processor in the air conditioner and comprises the following steps:
s301: an odor signal generated by the odor sensor is obtained.
Wherein, the smell sensor is arranged on the wall of the basin cavity of the intelligent closestool.
S302: the odor signal is analyzed to obtain the concentration of the first target gas.
S303: if the concentration of the first target gas rises and the rising amplitude within the first preset time reaches a first value, it is determined that the user is seated in the smart toilet and begins to defecate.
S304: and if the concentration of the first target gas is reduced and the reduction amplitude within the second preset time reaches a second value, determining that the user is out of the seat of the intelligent closestool, and controlling the intelligent closestool to carry out flushing operation.
S305: under the condition that no person sits on the intelligent closestool, if the concentration of the first target gas reaches a first concentration threshold value, the intelligent closestool is controlled to carry out heating and self-cleaning operations.
For specific implementation of steps S301 to S305, refer to the description in the foregoing, and are not described herein again. It should be noted that step S305 is optional, and in implementation, step S305 may not be included.
S306: an air quality parameter generated by the air quality detector is obtained.
Wherein, the air quality detector is arranged in the toilet, such as on the wall surface of the toilet. The air quality detector is used for detecting air quality parameters in the toilet.
In an implementation, the air quality parameter includes at least a concentration of the second target gas.
Wherein the second target gas is a gas that may adversely affect the body of the user. In practice, the second target gas may be one gas or a plurality of gases. For example, the second target gas may include one or more of carbon dioxide, formaldehyde, and ammonia.
Optionally, the air quality parameter may further include one or more of an indoor temperature, an indoor humidity, an inhalable particulate concentration, and a number of microbial colonies.
S307: and if the air quality parameter does not meet the preset air quality requirement, the air conditioner enters an operation mode.
The method comprises the steps of setting corresponding qualified ranges for all air quality parameters in advance, comparing all the air quality parameters in the toilet with the corresponding qualified ranges after the air quality parameters in the toilet are obtained, determining that the air quality parameters in the toilet do not meet preset air quality requirements if a specified number (1 or more) of the air quality parameters exceed the corresponding qualified ranges, and enabling the air conditioner to enter an operation mode to supply air to the toilet so as to improve the air quality in the toilet.
Alternatively, after step S307, there are provided:
s308: and if the concentration of the second target gas reaches a second concentration threshold value, performing peculiar smell removing operation, sterilizing operation and starting odor generator operation until a preset end condition is met.
The preset end condition may be: the concentration of the second target gas drops to a third concentration threshold. Alternatively, the preset end condition may be: the time length from the time when the air conditioner executes the peculiar smell removing operation, the sterilizing operation and the operation of starting the odor generator reaches a preset time length value.
