In this embodiment, two air guiding windows are provided, which are the first air guiding window 11 and the second air guiding window 12. The number of the air guides 20 is two, and the two air guides are respectively a first air guide 20 and a second air guide 20, the first air guide 20 includes a first wind shielding part 21 and a first wind guiding part 22, and the second air guide 20 includes a second wind shielding part 23 and a second wind guiding part 24.

In this embodiment, the wind blocking portion has a wind blocking position in a rotation stroke thereof, the wind blocking position being that the wind blocking portion is located in the air discharge duct, and a rotation stroke range of the wind blocking portion from the initial position to the wind blocking position is [0, 90]. Specifically, the wind blocking position of the wind blocking part refers to a position where the wind blocking part is located when the mobile air conditioner performs the return air mode. The pivoted angle of portion of keeping out the wind is 0 when initial position, and portion of keeping out the wind rotates towards the inside that connects the body, and the biggest angle of pivoted is 90, and when portion of keeping out the wind rotated 90 towards connecting the body inside, portion of keeping out the wind was mutually perpendicular with the wall that connects the body pipe wall, and the area of keeping out the wind of portion of keeping out the wind this moment is the biggest, and the windage of keeping out the wind is the biggest, and the efficiency of keeping out the wind is the highest. Therefore, the present embodiment defines the angular range of rotation of the windshield portion (i.e., the rotational stroke range) to be 0 ° to 90 °, inclusive.

Referring to fig. 3 and 4, in an embodiment, the wind guide portion has an initial position in a rotation stroke thereof, and the initial position is that the wind guide portion is located in the wind guide window to shield the wind guide window. Specifically, the air guiding portion is located on the air guiding window and blocks the air guiding window, so that smooth air flowing and discharging of air discharged from the air outlet 43 can be guaranteed, air flow cannot leak from the air guiding window, and air discharging efficiency is guaranteed.

In this embodiment, the air guiding portion has an air guiding position in a rotation stroke thereof, the air guiding position is a direction in which the air guiding portion is located outside the air exhaust channel and faces an air exhaust inlet, and a rotation stroke range of the air guiding portion from the initial position to the air guiding position is [0, 90].

Specifically, the wind blocking position of the wind blocking part refers to a position where the wind blocking part is located when the mobile air conditioner performs the return air mode. The pivoted angle of wind-break portion when initial position is 0, and the wind-break portion rotates towards the inside that connects the body, and the biggest angle of pivoted is for being less than 90, and the purpose that the biggest angle is less than 90 makes the wind-break portion rotate to the wall out-of-plumb (but be the acute angle) of wind-break portion and joint body pipe wall towards connecting the body outside, makes and forms the contained angle between wind-break portion and the wind-break portion, and the wind-break portion is towards the direction of the entry of airing exhaust, with the air current guide to the air intake, realizes the return air. Therefore, the present embodiment defines the angular range of rotation of the windshield portion (i.e., the rotational stroke range) to be 0 ° to 90 °, and 90 ° does not include the prime number. It is understood that the return air effect is not good in the range of 80 degrees to 90 degrees, and the preferred range of the rotation travel of the present embodiment may be 40 degrees to 80 degrees, or other value ranges, which are not limited herein.

When the mobile air conditioner operates in a cooling mode, hot air is discharged from the air outlet 43; when the mobile air conditioner operates in the heating mode, the cold air is discharged from the air outlet 43. The following embodiment is described by using the working principle of the mobile air conditioner operating in the cooling mode, and the working principle of the mobile air conditioner operating in the heating mode is similar to that in the cooling mode, which is limited to space and is only described briefly for simplicity, and is not described herein again.

Referring to fig. 3 and 4, it is assumed that the first wind blocking portion 21, the first wind guiding portion 22, the second wind blocking portion 23, and the second wind guiding portion 24 are I1, I2, I3, and I4, respectively. When the air conditioner works normally, I1, I2, I3 and I4 are all in a closed state. When I1, I2, I3 and I4 need to be opened, wherein the regulating valve of I1 is opened downwards, the regulating valve of I3 is opened upwards, the adjustable maximum angle of I1 and I3 is set to be 90 degrees, the adjustable times are b (b is determined according to the actual condition of the machine and can be preferably 2-5), and the angle is 90/b each time; the adjustable maximum angle of I2 and I4 is set to be L (L is determined according to the actual condition of the machine and is preferably 40-80 degrees), the adjustable times are set to be a (a is determined according to the actual condition of the machine and is preferably 2-5 degrees), and the angle is adjusted to be L/a each time. When the air pipe is used for refrigerating, hot air is discharged from the air pipe, and after the I1 or the I3 is opened, the air resistance of air supplied by the air pipe is increased, so that the load of a machine is increased, and the temperature of the evaporator can be increased. After I2 is opened, the hot air of the air pipe blows to the air inlet of the upper air duct along the guided outlet direction to enter the evaporator (the air blowing to the air inlet can reenter the air inlet under the action of negative pressure), and the heat load of the evaporator is increased. I4 opens the back, and hot-blast wind can blow to the condenser direction through lower wind channel air intake, leads to the condenser load to rise to also can lead to evaporation side temperature to rise, the rise of evaporimeter temperature is favorable to changing the frost and reduces the production of machine condensation.

When the air conditioner operates in heating, for preventing high temperature protection, because what air exit 43 blew out is cold wind, if temperature sensor detects that the air conditioner is about to get into when preventing high temperature protection, the accessible is adjusted I1, I2, I3, I4's mode, makes partial exhaust pipe cold wind get back to last wind channel or lower wind channel, carries out the same control program, can reach the purpose of cooling to avoid preventing high temperature protection, improved user experience.

The mobile air conditioner is provided with an air outlet 43, an air outlet pipe joint device is installed on the air outlet 43, the air outlet pipe joint device comprises a joint body, a first air guide piece 20 and a second air guide piece 20, the first air guide piece 20 is rotatably connected to the joint body, the first air guide piece 20 comprises a first air blocking portion 21 and a first air guiding portion 22, and the second air guide piece 20 comprises a second air blocking portion 23 and a second air guiding portion 24. As shown in fig. 5, the method includes the following steps S110-S120.

The first temperature protection condition is a judgment formula Q1: T-Tp > X (X is determined according to the actual condition of the air conditioner, and is preferably 2-4). When the air conditioner operates in a refrigerating mode, when the temperature T detected by the temperature sensor meets the judgment formula Q1: when the T-Tp is greater than X, the air conditioner operates normally. And when the absolute value of T-Tp is less than or equal to X, the air conditioner starts to execute a return air mode. It is understood that the first temperature protection condition may be other judgment manners, for example, the first temperature protection condition is another judgment formula | T-Tp ≧ X + Z, where Z may preferably be 2-5, which is not limited herein.

And S120, if a first temperature protection condition is met, controlling the first wind shielding part, the first wind guiding part, the second wind shielding part and the second wind guiding part to rotate according to a preset mode.

In the present embodiment, it is assumed that the first wind blocking portion, the first wind guiding portion, the second wind blocking portion, and the second wind guiding portion are I1, I2, I3, and I4, respectively. When the air conditioner performs the return air mode, I1, I2, I3, I4 are rotated in a preset manner. Among them, there are various preset modes, for example, the first: i1 → I2 → I3 → I4 (or I1 → I3 → I2 → I4) in sequence; and the second method comprises the following steps: i1 and I2 are opened to rotate sequentially or simultaneously, and then I3 and I4 are opened to rotate sequentially or simultaneously; and the third is that: i1 and I3 are opened to rotate sequentially or simultaneously, and then I2 and I4 are opened to rotate sequentially or simultaneously; and fourthly: i1, I2, I3 and I4 are opened and rotated simultaneously; and a fifth mode: opening rotation I1 alone; and a sixth mode: only rotations I1 and I2 are open; seventh, the method comprises: only rotations I3 and I4 are open; an eighth method: only rotations I1 and I3 are opened. That is, there are various combinations of the control operations of I1, I2, I3, and I4, and any control method may be used as long as the rotation of I1, I2, I3, and I4 is controlled to lower the exhaust efficiency and delay the temperature protection point, and the permutation and combination not listed in the present embodiment is equivalent to the configuration of the present embodiment and falls within the protection scope of the present application, and the present embodiment is not limited to the preset embodiment. When the opening quantity of the I1, I2, I3 and I4 is more, or the rotation angle is more, the more air return is realized. Therefore, the air return quantity can be adjusted by rotating the I1, the I2, the I3 and the I4 in different preset modes, and the purpose of secondary utilization of energy can be reasonably achieved.

In this embodiment, an alternative preset way is proposed to control the opening rotation of I1, I2, I3, I4. The maximum adjustable angle of I1 and I3 is set to be 90 degrees, the adjustable times are b (b is determined according to the actual situation of the machine and can be preferably 2-5), and the angle is 90/b each time, namely the unit rotation angle of I1 and I3 is 90/b. The adjustable maximum angle of I2 and I4 is set to be L (L is determined according to the actual condition of the machine and is preferably 40-80 degrees), the adjustable times are set to be a (a is determined according to the actual condition of the machine and is preferably 2-5), and the angle is adjusted to be L/a each time, namely the unit rotation angle of I2 and I4 is L/a. The first preset time period is t1, and the first preset time period may be, for example, 2min to 5min. The more the I1, I2, I3 and I4 are opened, the larger the return air quantity is, and the larger the rotation angles of I1, I2, I3 and I4 are, the more the return air quantity is obtained. Then the amount of return air is maximized when I1, I2, I3, I4 are all open and I1, I2, I3, I4 is maximized. In this embodiment, the air return amount is gradually increased from opening I1, and by increasing the rotation angle of I1, the unit rotation angle of one unit is increased each time, and the air return amount is further increased until the rotation angle of I1 reaches the maximum, which indicates how to adjust I1 at this time, and the air return amount cannot be further increased. Therefore, when the rotation angle of the I1 reaches the maximum, the I3 is controlled to rotate again at the moment, the air return amount is further increased, similarly, the adjustment is also realized by increasing the rotation angle of the I3, when the rotation angle of the I3 reaches the maximum, the I2 is opened again, and the like, and finally the I4 is opened again.

In one embodiment, as shown in fig. 7, the method for controlling a mobile air conditioner further includes the steps of: S130-S140.

And S130, judging whether a second temperature protection condition is met according to the current temperature and a preset protection temperature.

S140, if a second temperature protection condition is met, the operation is kept for the second preset time; if the second temperature protection condition is not satisfied, the process returns to the judgment of whether the rotation angle of the first windshield portion reaches the maximum angle (return to step S121).

In this embodiment, the second temperature protection condition is a judgment formula Q2: and | T-Tp | ≧ X + | T0-Tp | × (Y is a multiplier factor, which is determined according to the conditions of the air conditioner and the local climate environment, and preferably can be 0.2-0.6). The second preset time period is t2, and t2 is 20-40 min, for example.

Specifically, as described in connection with step S120, it is first determined whether I1 has reached the maximum, and if not, I1 is increased by 90/b and operated for t1 time (t 1 is determined according to the actual condition of the air conditioner, and preferably may be 2min to 5 min), and then a determination procedure Q2 is executed: if the judgment result is yes, the operation time T2 is operated according to the state (the value can be preferably selected to be 20-40 min according to the actual condition T2), then the I1, the I2, the I3 and the I4 are all restored to the initial positions (closed), the operation is carried out according to the normal state, and the temperature T of the temperature sensor is continuously detected; if | T-Tp | < X + | T0-Tp |. Times.Y, I1 increases the angle 90/b again (the opening angle is 2X 90/b at this moment), after running for T1 time, the judgment program Q2 is executed again, if the judgment is no, I1 increases the angle 90/b again (the opening angle is 3X 90/b at this moment), the judgment Q2 is executed again after running for T1, and in this way, the maximum opening angle of I1 is 90, and the adjustment times are b; if the air conditioner judges that the I1 is opened at the maximum angle, the program starts to adjust the I2, the maximum opening angle of the I2 is L, the adjustable times are a, the I2 adjusting process is the same as the I1, the I2 can adjust the maximum angle to be L (L is determined according to the actual condition of the air conditioner and is preferably 40-80 degrees), the adjustable times are a (a is determined according to the actual condition of the air conditioner and is preferably 2-5), and the angle is adjusted at each time to be L/a; if the judgment condition Q2 is not met after I2 is opened, then I3 and I4 are opened, the adjustment principle is the same as that of I1 and I2, and finally the state that I1, I2, I3 and I4 are opened at the maximum angle is shown in figure 4. If all the I1, I2, I3 and I4 are opened and the judgment Q2 cannot be met, the operation is directly carried out for t2 time according to the state, and then the normal state operation is recovered. Therefore, the frost formation can be avoided or delayed to the maximum extent to protect the machine from stopping or generate condensation.
