In some embodiments, the determining, in step S130, whether there is a misjudgment or an inaccurate detection condition in the indoor environment thermal bulb based on the target ambient temperature of the air conditioner in combination with the initial ambient temperature of the air conditioner or the detected ambient temperature of the air conditioner further includes: and a second process of determining whether the inner environment temperature sensing bulb has the condition of inaccurate detection according to the target environment temperature and the detection environment temperature of the air conditioner.

With reference to the schematic flow chart of an embodiment of determining whether the internal ambient temperature sensing bulb has the condition of inaccurate detection according to the target ambient temperature and the detected ambient temperature of the air conditioner in the method of the present invention shown in fig. 3, a specific process of determining whether the internal ambient temperature sensing bulb has the condition of inaccurate detection according to the target ambient temperature and the detected ambient temperature of the air conditioner in step S130 is further described, which includes: step S310 to step S350.

And S310, after the air conditioner operates for the first time, under the condition that the temperature detected by the indoor environment temperature sensing bulb is the target environment temperature of the air conditioner, adjusting the target pipe temperature of the indoor heat exchanger to the sum of the target environment temperature and the set temperature of the air conditioner, and controlling the rotating speed of an inner fan of the air conditioner to be unchanged.

Step S320, after the air conditioner operates for the second time, recording the detected ambient temperature of the air conditioner under the condition that the temperature degree is set in the stable degree area of the temperature detected by the indoor thermal bulb, wherein the detected ambient temperature of the air conditioner is the stable temperature Tx of the indoor environment at this moment. Wherein the set temperature is, for example, 2 ℃.

Step S330, determining whether a temperature difference between the detected ambient temperature of the air conditioner and the target ambient temperature of the air conditioner is within a set temperature range, for example, determining whether the temperature difference between the detected ambient temperature of the air conditioner and the target ambient temperature of the air conditioner is greater than a lower limit of the set temperature range, for example, -1 ℃, and less than an upper limit of the set temperature range, for example, 1 ℃.

Step S340, if it is determined that the temperature difference between the detected ambient temperature of the air conditioner and the target ambient temperature of the air conditioner is not within the set temperature range, determining that the detection of the indoor environment thermal bulb is inaccurate, and correcting the detected ambient temperature of the indoor environment thermal bulb to obtain a corrected temperature of the detected ambient temperature of the indoor environment thermal bulb, which is recorded as the corrected ambient temperature of the air conditioner, so as to control the air conditioner to continue to operate according to the corrected ambient temperature of the air conditioner.

Step S350, if the temperature difference value between the detected environment temperature of the air conditioner and the target environment temperature of the air conditioner is determined to be within the set temperature range, it is determined that the indoor environment thermal bulb is not in the condition of inaccurate detection, the detected environment temperature of the indoor environment thermal bulb does not need to be corrected, and the air conditioner continues to be controlled to continue to operate according to the detected environment temperature of the air conditioner based on the detected environment temperature of the indoor environment thermal bulb.

Specifically, fig. 8 is a schematic flow chart illustrating an embodiment of a method for correcting an ambient temperature detected by an ambient indoor temperature sensing bulb of an indoor unit of an air conditioner according to the present invention. As shown in fig. 8, the method for correcting the ambient temperature detected by the ambient indoor ambient temperature sensing bulb of the indoor unit of the air conditioner in the solution of the present invention includes:

and step 21, starting the air conditioner, and detecting the initial environment temperature by the indoor environment temperature sensing bulb to set the initial indoor environment temperature T0. The user sets an indoor temperature request as a user set temperature Tt.

And step 22, after the air conditioner is started for a running time t, detecting that the indoor temperature reaches a temperature Tt set by a user by the indoor environment temperature sensing bulb, and continuing running the air conditioner. At this time, the target tube temperature of the evaporator (i.e. the indoor heat exchanger) is adjusted to be Tt +/-2, the rotating speed of the internal fan is unchanged, and the operation is continued for a period of time x. When the indoor environment temperature sensing bulb detects that the temperature rise (or temperature drop) rate r is approximately equal to 0, the temperature detected by the indoor environment temperature sensing bulb tends to be stable, and the temperature Tx is measured and recorded as the indoor environment stable temperature Tx.

Step 23, calculating the value of the indoor environment stable temperature Tx-user set temperature Tt, and determining whether (the indoor environment stable temperature Tx-user set temperature Tt) is the same as (-1,1): if so, go to step 26, otherwise go to step 24.

In step S140, if it is determined that there is no erroneous determination and no inaccurate detection in the indoor environment thermal bulb, the detected environment temperature of the indoor environment thermal bulb does not need to be corrected, and the air conditioner continues to be controlled to continue to operate according to the detected environment temperature of the air conditioner based on the detected environment temperature of the indoor environment thermal bulb.

In step S150, if it is determined that there is a misjudgment or inaccurate detection condition in the indoor environment bulb, correcting the detected ambient temperature of the indoor environment bulb to obtain a corrected ambient temperature of the detected ambient temperature of the indoor environment bulb, and recording the corrected ambient temperature as the corrected ambient temperature of the air conditioner, so as to control the air conditioner to continue to operate according to the corrected ambient temperature of the air conditioner.

According to the scheme, the problem that the indoor environment temperature sensing bulb is influenced by the temperature of the evaporator (namely the indoor heat exchanger) and the indoor environment temperature is not accurately detected can be solved, whether the indoor environment temperature sensing bulb is inaccurate in detection or not can be judged, the indoor environment temperature can be corrected, the working state of the air conditioner can be adjusted through the misjudgment value range of the indoor environment temperature sensing bulb, the comfort requirement of the indoor unit of the air conditioner is met, and the user experience is improved.

In the scheme of the invention, whether the indoor environment temperature sensing bulb measures the temperature accurately is judged, if so, the indoor environment temperature sensing bulb can normally operate, and if not, the indoor environment temperature sensing bulb enters a correction program. Specifically, the temperature of the indoor environment temperature sensing bulb can be judged by mistake under the condition that the temperature measurement of the indoor environment temperature sensing bulb is inaccurate, and the indoor temperature is adjusted according to the misjudged temperature, so that the room temperature reaches the temperature actually set by a user. Like this, according to the operation of the air conditioner of control according to the correction result, influence the air conditioner refrigeration or heating capacity under the indoor environment temperature sensing package erroneous judgement condition to a certain extent to influence the problem of user's travelling comfort, satisfy air conditioner indoor unit travelling comfort requirement, improve user experience.

In the relevant scheme, the problem of inaccurate temperature measurement of the indoor environment temperature sensing bulb is solved only by setting a specific compensation value in a program, the compensation mode is single and inaccurate, if the indoor environment temperature sensing bulb is tested accurately, the single compensation value can cause the air conditioner to work excessively, and the requirement of a user on comfort is also not met. According to the scheme of the invention, whether the indoor environment temperature sensing bulb is misjudged is judged firstly, and then temperature compensation is carried out according to the misjudgment value of the indoor environment temperature sensing bulb, so that the room temperature is close to the temperature set by a user to the maximum extent, and the comfort and the reliability of the air conditioner are improved.

In some embodiments, in step S150, the detected ambient temperature of the indoor ambient temperature sensing bulb is corrected to obtain a corrected temperature of the detected ambient temperature of the indoor ambient temperature sensing bulb, which is recorded as a specific process of the corrected ambient temperature of the air conditioner, see the following exemplary description.

Referring to fig. 4, a flowchart of an embodiment of correcting the detected ambient temperature of the indoor ambient temperature sensing bulb in the method of the present invention further illustrates a specific process of correcting the detected ambient temperature of the indoor ambient temperature sensing bulb in step S150, including: step S410 to step S430.

As shown in fig. 8, the method for correcting the ambient temperature detected by the ambient indoor ambient temperature sensing bulb of the indoor unit of the air conditioner in the solution of the present invention further includes:

step 24, if

The indoor environment temperature sensing bulb detects that the indoor environment temperature is inaccurate and cannot meet the user requirement, and the air conditioner enters a correction operation mode. Since the difference between the indoor ambient temperature and the detected temperature of the indoor ambient bulb is the indoor ambient stable temperature Tx and the user set temperature Tt, the indoor temperature between the indoor ambient stable temperature Tx and the user set temperature Tt needs to be compensated. The air conditioner operates at an increased frequency to continue cooling (or heating), so that the indoor temperature detected by the indoor environment temperature sensing bulb is Tt- (Tx-Tt), namely 2Tt-Tx. Let T be the indoor temperature detected by the corrected indoor environment bulb, i.e., the detected temperature T =2 user set temperature Tt — indoor environment stable temperature Tx. At this time, the indoor environment temperature sensing bulbThe indoor ambient temperature at the detected indoor temperature T is the user's actual set temperature.

That is, if

Controlling the compressor of the air conditioner to perform frequency-increasing operation, entering correction, setting the detected temperature as T, stopping the compressor of the air conditioner to perform frequency-increasing operation continuously when the detected temperature T =2 user set temperature Tt-indoor environment stable temperature Tx, and controlling the compressor of the air conditioner to maintain current frequency operation.

For example: assuming that the user sets the heating mode, the user-set temperature Tt =26 ℃, and the indoor environment stable temperature Tx =23 ℃ after the evaporator (i.e., the indoor heat exchanger) is operated at the user-set temperature Tt ± 2 for a certain time x. At this time, the indoor environment stable temperature Tx-the user set temperature

The temperature of the indoor environment temperature sensing bulb is inaccurate and needs to be corrected. The difference between the detected temperature of the indoor environment temperature sensing bag and the actual room temperature is the stable indoor environment temperature Tx-the user set temperature Tt, that is, the room temperature at 3 ℃ needs to be compensated, that is, when the detected temperature of the indoor environment temperature sensing bag is Tt- (Tx-Tt) = Tt + | (Tx-Tt) | =26- (-3) =26+3=29 ℃, the indoor temperature can reach about 26 ℃, and the temperature is set by the user. However, when the air conditioner is used in a cooling mode, the room temperature needs to be lowered, and the formula needs to be changed into Tt- | (Tx-Tt) |, so that the cooling and heating modes need to be separately described. Tt- (Tx-Tt) can better cover two situations of cooling and heating, and is convenient for program setting.

That is, the indoor temperature meets the indoor set temperature requirement, and the air conditioner operates normally.
