Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A control method of an air conditioning system of an electric vehicle according to an embodiment of the present invention is described below.

The air conditioning system includes a compressor, a heater, and a fan, and has a standby state and an operating state in which the air conditioning system has a cooling mode, a heating mode, and a natural wind mode.

It is understood herein that the standby state refers to a state in which the system is not operated, and a state in which the compressor, the heater, and the fan are not operated. The working state refers to a state when the system runs, the system can blow air into the cab when running, and at least one of the compressor, the heater and the fan runs.

The natural wind mode refers to a working mode that the system blows natural wind into the cab, namely the system neither cools nor heats blown air. The cooling mode refers to an operation mode in which the system cools air blown into the cab, that is, blown air is cool air relative to natural air. The heating mode refers to an operation mode in which the system heats air blown into the cab, that is, the blown air is hot air relative to natural air.

Specifically, the air conditioning system further comprises a condenser, an evaporator, a throttling element and the like, the compressor is connected with the condenser, the throttling element, the evaporator and other devices through refrigerant pipelines, and the compressor, the condenser, the evaporator and the throttling element form a refrigerant circulation channel. The refrigerant circularly flows in the channel, and the circulating refrigerant is evaporated in the evaporator to absorb heat so as to absorb the heat of the air flowing through the evaporator. It is understood that the refrigerant circulation passage is in a circulation state when the compressor is operated, and the refrigerant flows in the refrigerant circulation passage to cool the air passing through the evaporator. The structures and operating principles of the compressor, the evaporator, the condenser and the throttling element are well known in the art and will not be described in detail herein.

More specifically, the heater is used for heating air flowing through the heater, and optionally, the heater is an electric heater, such as an electric heating tube, an electric heating wire, or the like.

More specifically, a blower may be used to blow air through the evaporator, heater, and into the cab. Of course, there may be more than one fan, some fans are used to blow the cooled air into the cab, some fans are used to blow the heated air into the cab, and other fans are only used to blow natural air into the cab. The number of the fan may be one, the fan may blow air after cooling or heating into the cab, and the fan may also blow natural wind into the cab, which is not particularly limited herein.

The heater and the fan can adopt the structure of the heater and the fan disclosed in the prior art, and the specific structure and the working principle of the heater and the fan are not repeated here.

In the embodiment of the invention, in the natural wind mode, the compressor and the heater are both closed, and the fan runs to blow air.

In the cooling mode, the compressor is operated and the heater is turned off, in the heating mode, the compressor is turned off and the heater is operated, and in both the cooling mode and the heating mode, the blower is operated to blow cooled or heated air into a cab of the electric vehicle.

That is, only the fan is operated when the air conditioning system is operating in the natural wind mode. When the air conditioning system is used for refrigerating, only the refrigerant circulating channel and the fan are operated, and the heater is in a closed state in the refrigerating process. When the air conditioning system heats, only the heater and the fan operate, and the refrigerant circulating channel is in a closed state in the heating process.

In addition, some conventional electric vehicles also have a cooling function, and the refrigerant circulation passage and the heater are normally operated simultaneously during cooling, that is, the electric vehicles also heat air by the heater during cooling. Obviously, this method will cause the increase of the running energy consumption of the electric vehicle, and the electric vehicle needs to store more electric quantity to maintain normal running, which is not beneficial to the electric vehicle to reduce the weight of the storage battery.

In the electric automobile in the embodiment of the invention, the air conditioning system closes the heater during refrigeration and closes the refrigerant circulating channel during heating, so that unnecessary energy loss is avoided, and the operating cost of the air conditioning system is reduced.

According to the control method of the air conditioning system of the electric automobile, the compressor is started and the heater is closed during refrigeration, and the heater is started and the compressor is closed during heating, so that the energy consumption and the system operation cost of the electric automobile are reduced, the weight of the storage battery is favorably reduced, and the miniaturization and the light weight development of the electric automobile are favorably realized.

In an embodiment of the present invention, the air conditioning system includes a temperature adjustment knob having a zero position, the temperature adjustment knob being provided with one of a cold wind stop and a hot wind stop in a clockwise direction of the zero position, and the temperature adjustment knob being provided with the other of the cold wind stop and the hot wind stop in a counterclockwise direction of the zero position.

That is to say, the temperature adjusting knob has different gears, and the temperature adjusting knob is used for adjusting the air-out temperature of the air conditioning system, and when the air conditioning system starts the cooling or heating mode, the cooling capacity or the heating capacity can be adjusted by adjusting the gear of the temperature adjusting knob.

The temperature adjusting knob is also provided with a cold air side starting gear at the downstream of the cold air gear in the direction from the zero gear to the cold air gear, and is also provided with a hot air side starting gear at the downstream of the hot air gear in the direction from the zero gear to the hot air gear. The cold air side starting gear and the hot air side starting gear are arranged, so that a passenger can conveniently and quickly start a refrigeration mode and a heating mode.

It will be appreciated that on a hot summer day, the cabin is generally warmer and that passengers generally desire a rapid decrease in air temperature immediately after entering the cabin. It is easy for the passenger to first pay attention to the temperature adjustment knob and to quickly turn the temperature adjustment knob. And set up cold wind side on the temperature regulation knob and start the shelves, be exactly convenient for the passenger can start the refrigeration mode fast when wanting to transfer the low temperature. Similarly, the temperature adjusting knob is provided with a hot air side starting gear, so that the passenger can conveniently and quickly start the heating mode when the temperature is adjusted.

In the embodiment of the invention, a cold air side neutral position is arranged between the cold air gear and the cold air side starting gear, and a hot air side neutral position is arranged between the hot air gear and the hot air side starting gear.

When the temperature adjusting knob rotates from the zero gear to the cold air side starting gear, the temperature adjusting knob at least rotates to pass through the cold air gear and the cold air side neutral gear. When the cold air side neutral position is rotated, the working mode of the system is unchanged, and when the cold air side neutral position is rotated to the cold air side starting gear, the refrigeration mode can be started by the system.

The setting of cold wind side neutral lies in increasing the gear number from zero gear to cold wind side between the starting gear, and like this, the system can not refrigerate easily when passenger's small-angle rotated temperature knob, can refrigerate only after temperature knob has rotated a plurality of gears and reached cold wind side starting gear from zero gear.

Similarly, the arrangement of the hot air side neutral position is that the gear number from the zero gear to the hot air side starting gear is increased, so that the system cannot be heated easily when a passenger rotates the temperature adjusting knob at a small angle, and only after the temperature adjusting knob rotates a plurality of gears from the zero gear and reaches the hot air side starting gear, heating can be performed.

From the perspective of the passenger, if the passenger largely rotates the temperature adjustment knob, this action can reflect the urgent mood that the passenger wants to rapidly cool down or rapidly heat up. Therefore, the arrangement of the cold air side neutral position and the hot air side neutral position can avoid the condition that a passenger does not touch the temperature adjusting knob or operates the temperature adjusting knob randomly to cause refrigeration or heating, thereby avoiding energy waste and reducing the driving range.

In some embodiments, at least two cold air side neutral positions are provided between the cold air gear and the cold air side starting gear, and at least two hot air side neutral positions are provided between the hot air gear and the hot air side starting gear. The number of the neutral positions is increased, and passengers can only reach the cold air side starting gear after the cold air side neutral positions rotate at least two cold air side neutral positions from the cold air side gear so as to start the cooling mode. Similarly, the passenger can only reach the hot wind side starting gear after the hot wind gear rotates at least two hot wind side neutral positions so as to start the heating mode.

The increase in the number of neutral positions further ensures that the passenger can think of cooling when he/she turns the temperature adjustment knob to the cold air side start gear, and also think of heating when he/she turns the temperature adjustment knob to the hot air side start gear. Thereby further avoiding the energy waste caused by that the passenger does not touch the temperature adjusting knob or operates the temperature adjusting knob at will, and avoiding reducing the driving range.

According to the control method of the air conditioning system of the electric automobile, provided by the embodiment of the invention, the cold air side starting gear and the hot air side starting gear are arranged on the temperature adjusting knob, so that a passenger can conveniently and rapidly start the cooling mode and the heating mode through the temperature adjusting knob. The cold air side neutral position is arranged between the cold air gear and the cold air side starting gear, and the hot air side neutral position is arranged between the hot air gear and the hot air side starting gear, so that energy waste caused by that a passenger does not touch the temperature adjusting knob or operates the temperature adjusting knob randomly can be avoided, and the driving range is prevented from being reduced.

According to the control method of the air conditioning system of the electric automobile, the air conditioning system comprises the air volume adjusting knob used for controlling the operation of the fan, the air volume adjusting knob is provided with the air volume gear, the air volume neutral gear and the fan braking gear, and the air volume neutral gear is positioned between the air volume gear and the fan braking gear in the direction from the fan braking gear to the air volume gear. When the air quantity adjusting knob is rotated to the air quantity gear in the standby state, the fan is operated to run in a natural wind mode. In the process of natural wind mode operation, when the air volume adjusting knob rotates to a fan braking gear, the fan stops running.

When the air quantity adjusting knob rotates from the air quantity gear to the fan braking gear, the air quantity adjusting knob at least rotates to pass through the air quantity neutral gear. When the wind volume is rotated to the neutral position, the wind volume of the fan is unchanged, and when the wind volume is rotated to the braking gear of the fan, the fan can be braked and shut down.

The setting of amount of wind neutral lies in increasing the gear number from the amount of wind shelves to the fan braking shelves, and like this, the fan can not shut down when passenger's small-angle rotated the amount of wind adjust knob, and only can shut down after the amount of wind adjust knob has rotated at least one gear and reached fan braking shelves from the amount of wind shelves.

From the perspective of passengers, if the passenger has a large volume air volume adjusting knob, the action can reflect that the passenger really wants to turn off the fan. If the air volume adjusting knob is rotated in a small amplitude, the air volume adjusting knob does not necessarily represent that a passenger wants to turn off the fan, and perhaps the passenger does not touch the air volume adjusting knob or operates the air volume adjusting knob at will.

Therefore, the arrangement of the air volume adjusting knob can avoid that a passenger does not touch the air volume adjusting knob or operates the air volume adjusting knob at will to cause the shutdown of the fan, thereby avoiding energy waste.

Obviously, the current impact is large when the fan is turned on or off, and the energy consumption is high. If the fan is repeatedly switched on and off due to poor operation, the energy is not saved.

In some embodiments, at least two air volume neutral positions are arranged between the air volume gear and the fan braking gear, the number of the neutral positions is increased, and passengers can reach the fan braking gear only after rotating the at least two neutral positions from the air volume gear so as to turn off the fan.

The increase of the number of the neutral positions can further ensure that when the passenger rotates the air volume adjusting knob to the braking gear of the fan, the passenger thinks about the idea of closing the fan, thereby further avoiding the energy waste caused by the fact that the passenger does not touch the air volume adjusting knob or operates the air volume adjusting knob at will, and avoiding the reduction of the driving range.

According to the control method of the air conditioning system of the electric automobile, disclosed by the embodiment of the invention, the air quantity gear and the fan braking gear are arranged on the air quantity adjusting knob, so that a passenger can conveniently and rapidly open and close the natural wind mode through the air quantity adjusting knob. The air quantity neutral position is arranged between the air quantity gear and the fan braking gear, so that energy waste caused by that a passenger does not touch the air quantity adjusting knob or operates the air quantity adjusting knob randomly can be avoided, and the driving range is prevented from being reduced.

In some embodiments, in an operating state, the air conditioning system has a cooling mode and a heating mode in which the fan is operated to blow cooled or heated air into the cab of the electric vehicle.

Specifically, the cooling mode is an operation mode in which the system cools air blown into the cab, that is, the blown air is cool air with respect to natural air. The heating mode refers to an operation mode in which the system heats air blown into the cab, that is, the blown air is hot air relative to natural air.

Specifically, the air conditioning system further comprises a compressor, a condenser, an evaporator, a throttling element and the like, wherein the compressor is connected with the condenser, the throttling element, the evaporator and other devices through refrigerant pipelines, and the compressor, the condenser, the evaporator and the throttling element form a refrigerant circulation channel. The refrigerant circularly flows in the channel, and the circulating refrigerant is evaporated in the evaporator to absorb heat so as to absorb the heat of the air flowing through the evaporator. It is understood that the refrigerant circulation passage is in a circulation state when the compressor is operated, and the refrigerant flows in the refrigerant circulation passage to cool the air passing through the evaporator. The structures and operating principles of the compressor, the evaporator, the condenser and the throttling element are well known in the art and will not be described in detail herein.

In some embodiments, the compressor start-up requires that a preset condition be met. When the ambient temperature is lower, the system can not start the refrigeration mode, reduces the loss of compressor, avoids the energy waste that the maloperation leads to.

For example, in some examples, the compressor start-up needs to satisfy two preset conditions, condition 1, where the evaporator temperature is 2 degrees or higher, and condition 2, where the ambient temperature is 5 degrees or higher.

In some embodiments, the air conditioning system includes a cooling actuator and a heating actuator, and the cooling mode is activated when the cooling actuator is activated in a standby state. In a standby state, when the heating starting piece is triggered, the heating mode is started.

That is to say, when the system is not started, the refrigeration mode can be started by triggering the refrigeration starting piece, and the compressor and the fan are started to operate after the refrigeration starting piece is triggered.

When the system is not started, the heating mode can be started by triggering the heating starting piece, and the heater and the fan are started to operate after the heating starting piece is triggered.

Specifically, during the operation of the system in the cooling mode, when the cooling starting piece is triggered, the air conditioning system exits the cooling mode; when the heating start-up is triggered during operation of the system in the heating mode, the air conditioning system exits the heating mode. That is to say, the refrigeration starter is the switch of refrigeration mode, and refrigeration mode opens when single trigger, and refrigeration mode ends when triggering twice. The heating starting piece is a switch of a heating mode, the heating mode is started when the heating starting piece is triggered once, and the heating mode is finished when the heating starting piece is triggered twice.

In some embodiments, during operation of the system in the cooling mode, when the cooling activation is triggered, the air conditioning system exits the cooling mode and enters the natural wind mode; during operation of the system in the heating mode, when the heating trigger is triggered, the air conditioning system exits the heating mode and enters the natural wind mode.

That is, if the corresponding actuating member is activated during cooling or heating of the system, the wind blown into the cab by the system is changed into natural wind.

Therefore, after the cooling mode or the heating mode is closed, natural wind still blows in the cab, airflow in the cab is promoted to circulate, and the temperature in the cab tends to be balanced. And after the cooling mode or the heating mode is closed, certain natural wind still blows to the passengers, so that the air flow is kept smooth and fresh, and the passengers cannot feel suffocated immediately.

In some embodiments, during operation of the system in the cooling mode, when the heating actuator is triggered, the air conditioning system exits the cooling mode and enters the heating mode;

during operation of the system in a heating mode, when the refrigeration activation is triggered, the air conditioning system exits the heating mode and enters a cooling mode.

That is, during the operation in the cooling mode, if heating is required, the heating starting member can be directly triggered, and the system can be switched from the cooling mode to the heating mode. In this way, the step of turning off the cooling mode is saved.

Similarly, during the operation of the heating mode, if cooling is needed, the cooling starting piece can be directly triggered, and the system can be switched from the heating mode to the cooling mode. In this way, the step of turning off the heating mode is saved.

By the arrangement, when the system is required to be switched from the refrigeration mode to the heating mode or from the heating mode to the refrigeration mode, one action can be switched in place conveniently, and the control is simpler.

In some embodiments, the cooling mode is provided with N cooling levels in which the cooling capacity is gradually increased from level 1 to N, where N is an integer of 2 or more. The heating mode is provided with M heating levels with the heating quantity gradually increasing from 1 level to M levels, wherein M is an integer greater than or equal to 2.

In some embodiments, in the standby state, when the refrigeration actuator is activated, the system operates the refrigeration mode at a level 1 refrigeration level. That is, when the refrigeration starting member is triggered in the standby state, the system operates with the minimum refrigeration capacity, and the refrigeration capacity is gradually increased along with the rise of the refrigeration level. By the arrangement, the refrigerating capacity is gradually increased from the minimum, and the damage caused by overlarge impact of the system load during the initial refrigeration is avoided.

In some embodiments, in the standby state, when the heating starter is triggered, the system operates the heating mode at a level 1 heating level. That is, when the heating starter is activated in the standby state, the system is operated with the minimum heating amount, and the heating amount is gradually increased as the heating level is increased. By the arrangement, the heating quantity is gradually increased from the minimum, and damage caused by overlarge system load impact at the beginning of heating is avoided.

In some embodiments, during the operation of the system in the cooling mode, when the cooling starting piece or the heating starting piece is triggered, the air volume of the fan is unchanged; in the process that the system runs in the heating mode, when the refrigeration starting piece or the heating starting piece is triggered, the air volume of the fan is unchanged.

In some embodiments, the air conditioning system turns on the natural wind mode when the temperature adjustment knob is rotated to the cold wind range or the hot wind range in the standby state.

That is, when the temperature adjustment knob is turned to the cold air position during the standby of the system, the air blown out by the system is natural air. When the system is in standby, the temperature adjusting knob is rotated to the hot air gear, and the air blown out by the system is also natural air.

Of course, the embodiment of the present invention is not limited thereto, for example, when the temperature adjustment knob is turned to the cold wind gear or the hot wind gear during standby, the air conditioning system may still be kept in the standby state, and the system still does not blow air.

In some specific examples, in the standby state, when the temperature adjustment knob is rotated to the cold air side starting gear, the system operates the cooling mode at the N-stage cooling level. That is, when the temperature adjustment knob is rotated to the cold air side starting gear in the standby state, the system cools at the maximum cooling level. Like this, when the passenger feels in the driver's cabin too hot, can open the refrigeration mode fast, and can directly open the refrigerating output to the biggest, make the rapid cooling in the driver's cabin.

Also, in the standby state, when the temperature adjustment knob is rotated to the hot wind side start gear, the system operates the heating mode at the M-level heating level. That is, when the temperature adjustment knob is rotated to the hot wind side start gear in the standby state, the system heats at the maximum heating level. Thus, when the passenger feels the cab is too cold, the heating mode can be quickly started, and the heating quantity can be directly increased to the maximum, so that the cab is quickly increased.

By the arrangement, when the system needs to be rapidly cooled or heated, one action can be conveniently converted into the maximum cooling level or the maximum heating level, and the control is more concise.

In some specific examples, during operation of the air conditioning system in the cooling mode, if the temperature adjustment knob is rotated to the cool air side start gear, the cooling level of the system may be increased to N level.

During the operation of the air conditioning system in the heating mode, if the temperature adjustment knob is rotated to the hot wind side actuating stage, the heating level of the system is increased to M level.

In some embodiments, during operation of the air conditioning system in the cooling mode, when the temperature adjustment knob is rotated to the zero position or the hot wind position, the air conditioning system exits the cooling mode and enters the natural wind mode; when the temperature adjusting knob is rotated to a zero gear or a cold wind gear during the operation of the air conditioning system in the heating mode, the air conditioning system exits the heating mode and enters a natural wind mode. That is, the purpose of closing the cooling mode and the heating mode can be achieved by rotating the temperature adjusting knob, and the control is convenient.

In some embodiments, during operation of the air conditioning system in the cooling mode, when the temperature adjustment knob is rotated to the hot air side starting gear, the air conditioning system exits the cooling mode and enters the heating mode; when the temperature adjusting knob is rotated to the cold air side starting gear in the process that the air conditioning system operates in the heating mode, the air conditioning system exits the heating mode and enters the cooling mode.

That is, during the operation of the cooling mode, if heating is required, the temperature adjusting knob can be turned to the hot air side starting gear, and the system can be switched from the cooling mode to the heating mode. In this way, the step of turning off the cooling mode is saved.

Similarly, during the operation of the heating mode, if cooling is needed, the temperature adjusting knob can be rotated to the cold air side starting gear, and the system can be switched from the heating mode to the cooling mode. In this way, the step of turning off the heating mode is saved.

By the arrangement, when the system is required to be switched from the refrigeration mode to the heating mode or from the heating mode to the refrigeration mode, one action can be conveniently switched in place, and the control is simple.

In some embodiments, the cold wind gear on the temperature adjusting knob comprises a plurality of gears. During the operation of the system in the cooling mode, the temperature adjusting knob can be switched among a plurality of gears of the cold air gear, so that the cooling level of the system can be correspondingly switched. The hot air gear on the temperature adjusting knob comprises a plurality of gears, the temperature adjusting knob can be switched among the plurality of gears of the hot air gear in the process that the system runs in the heating mode, and the heating level of the system can be correspondingly switched.

In some embodiments, during the operation of the system in the cooling mode, when the temperature adjusting knob is rotated to the hot air gear and the rotation speed of the temperature adjusting knob is greater than or equal to the first predetermined rotation speed, the system exits the cooling mode and enters the heating mode.

In some embodiments, during the operation of the system in the heating mode, when the temperature adjustment knob is rotated to the cold air position and the rotation speed of the temperature adjustment knob is greater than or equal to the second predetermined rotation speed, the system exits the heating mode and enters the cooling mode.

From the perspective of the passenger, when the passenger rapidly turns the temperature adjustment knob, it indicates that the passenger urgently wants the indoor temperature to be rapidly cooled down or rapidly heated up. Therefore, the design can meet the requirements of passengers more.

In some embodiments, when the air conditioning system operates in the cooling mode, when the air volume adjusting knob is rotated to the fan braking gear, the fan stops running and the system exits the cooling mode; when the air conditioning system operates in the heating mode, when the air volume adjusting knob rotates to the braking gear of the fan, the fan stops operating and the system quits the heating mode.

It can be understood that, in both the cooling mode and the heating mode, the fan needs to be turned on to supply air, and after the fan is turned off, the cooled or heated air cannot be supplied into the cab, so that the cooling mode or the heating mode needs to be turned off.

The air quantity adjusting knob is arranged in such a way that the refrigeration mode or the heating mode can be closed through one action, the fan can be closed simultaneously, and the control is more concise.

In some embodiments, the air quantity gear is a stepless speed regulating gear to realize stepless regulation of the air quantity of the fan.

A control method of the air conditioning system in this embodiment is described below with reference to one specific embodiment of fig. 11 and 12.

In fig. 11, the lower round button is an air volume adjusting knob, and the upper round pattern in fig. 11 is an adjusting effect chart compared with the air volume adjusting knob. That is, when the air volume adjusting knob is turned, it can be considered as the adjustment of the air volume level as indicated by the upper circular pattern in fig. 11. It can be understood here that the air volume adjusting knob can adjust the air volume by adjusting the air speed and the fan power, and is not limited here.

In the clockwise direction, the air volume adjusting knob is sequentially provided with a fan braking gear, two air volume neutral positions and seven air volume gears, the seven air volume gears are sequentially increased from 1 to 7 along the gear in the clockwise direction, and the corresponding air volume has 7 gears.

Wherein, two gears on the left side of the 1 gear are air volume neutral gears, and the gears have no corresponding air speed;

two gears on the left side of the 1 gear are fan braking gears marked with OFF, and a user can turn OFF the fan by quickly rotating to the gear, namely turn OFF the air conditioning system, which is equal to an OFF key on an air conditioning control panel in the prior art.

The adjusting method of the air volume adjusting knob comprises the following steps:

if the air volume is 1 gear, the left-hand three gears or more can trigger OFF;

if the air volume is 2 grades, the left-hand four grades and above can trigger OFF;

if the air volume is 3 grades, the OFF can be triggered by rotating the five grades left and above;

if the air volume is 7 grades, the left-hand nine grades or more can trigger OFF.

When the passenger normally selects the air volume adjusting knob to the 1 st gear or the air volume neutral position, the aim of minimum air volume modulation can be achieved, and the passenger can be turned off when the air volume adjusting knob is rotated to the left of the air volume neutral position.

In the embodiment of the invention, the air volume gear can also be set to be 360-degree electrodeless. Taking the example shown in fig. 11 as an example, that is, after the air volume adjusting knob is rotated by 7 th gear, the air volume adjusting knob can still be rotated continuously and then the air volume can be further increased, for example, after 7 th gear, the air volume adjusting knob can be further increased to 8 th gear, 9 th gear, etc.

The bottom round button in fig. 12 is the temperature control member, and the two round patterns at the top and middle in fig. 12 are the adjusting effect graphs compared with the temperature control member. That is, the temperature control member is adjusted to be viewed as adjusting the cooling level and the heating level as indicated by the uppermost circular pattern in fig. 12, and the temperature control member is adjusted to be viewed as adjusting the indoor temperature as indicated by the middle circular pattern in fig. 12.

The temperature control part is a temperature adjusting knob, the temperature adjusting knob is provided with a zero gear, the temperature adjusting knob is provided with a hot air gear in the clockwise direction of the zero gear, and the temperature adjusting knob is provided with a cold air gear in the anticlockwise direction of the zero gear. Wherein, cold wind shelves constitute above-mentioned first shelves, and hot-blast shelves constitute above-mentioned third shelves.

In the direction from zero gear to cold wind shelves, the temperature regulation knob still is equipped with cold wind side at the low reaches of cold wind shelves and starts the shelves, that is to say that temperature regulation knob is equipped with zero gear, cold wind shelves and cold wind side in proper order and starts the shelves in the anticlockwise.

In the direction from the zero gear to the hot air gear, the temperature adjusting knob is also provided with a hot air side starting gear at the downstream of the hot air gear, namely the temperature adjusting knob is sequentially provided with the zero gear, the hot air gear and the hot air side starting gear in the clockwise direction.

Wherein, cold wind side starting gear constitutes the second gear, and hot wind side starting gear constitutes the fourth gear. In a standby state, when the temperature adjusting knob rotates to the cold air side starting gear, the system starts a refrigeration mode, and when the temperature adjusting knob rotates to the hot air side starting gear, the system starts a heating mode.

And a cold air side neutral position is arranged between the cold air gear and the cold air side starting gear, and a hot air side neutral position is arranged between the hot air gear and the hot air side starting gear.

Specifically, two cold air side neutral positions are arranged between the cold air gear and the cold air side starting gear, and two hot air side neutral positions are arranged between the hot air gear and the hot air side starting gear. Namely, the cold air side neutral position has two gears, and the hot air side neutral position also has two gears.

More specifically, as shown by the uppermost circular pattern in fig. 12, the temperature adjustment knob has a 0 th step at the uppermost middle. The cold air gear has four gears which are respectively-1, -2, -3 and-4. The hot wind gear has four gears, which are +1, +2, +3, + 4.

As shown by the uppermost circular pattern in fig. 12, the temperature adjustment knob is sequentially provided with 4 cold air stops, 2 cold air side neutral positions and 1 cold air side start stop in the counterclockwise direction of the 0 th stop, and is sequentially provided with 4 hot air stops, 2 hot air side neutral positions and 1 hot air side start stop in the clockwise direction of the 0 th stop.

The refrigerating mode has 4 refrigerating grades, the 4 refrigerating grades are-1 grade, -2 grade, -3 grade and-4 grade according to the increment of refrigerating capacity, the heating mode also has 4 heating grades, and the 4 heating grades are +1 grade, +2 grade, +3 grade and +4 grade according to the increment of heating capacity.

The adjusting method of the temperature adjusting knob comprises the following steps:

in a standby state, the temperature adjusting knob is rotated leftwards,

the left-hand gear is adopted, the refrigeration and heating functions are not started, and the air conditioner naturally blows;

the left-hand rotation is two gears, the refrigeration and heating functions are not started, and the air conditioner naturally blows;

the left-hand three-gear air conditioner has the advantages that refrigeration and heating functions are not started, and the air conditioner naturally blows air;

the left-hand four-gear air conditioner has the advantages that refrigeration and heating functions are not started, and the air conditioner naturally blows air;

the left-hand five-gear air conditioner has the advantages that refrigeration and heating functions are not started, and the air conditioner naturally blows air;

the refrigeration and heating functions are not started when the air conditioner is rotated to the sixth gear on the left, and the air conditioner naturally blows air;

and (3) rotating at seven or more left gears, starting a refrigeration mode by the air conditioner, discharging cold air from the air conditioner (the starting condition of the compressor is 1, the temperature of an evaporator is more than 2 ℃, and the ambient temperature is more than 5 ℃), and setting the refrigeration level to be-4.

In a standby state, the temperature adjusting knob is rotated rightwards,

the right rotation is in the first gear, the refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

the right rotation is in two gears, the refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

the right-hand rotation is in three gears, the refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

the right rotation is in the fourth gear, the refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

the right-hand five-gear air conditioner has the advantages that refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

the right-hand gear is six, the refrigeration and heating functions are not started, and the air conditioner is naturally ventilated;

and (4) rotating right by seven gears or more, starting a heating mode of the air conditioner, and enabling the air conditioner to output hot air, wherein the heating level is + 4.

In addition, the refrigeration starting piece and the heating starting piece are both buttons, and the refrigeration starting piece and the heating starting piece are both arranged on the temperature adjusting knob.

In a standby state, after a refrigeration starting piece is pressed down, the air conditioner starts a refrigeration mode (the starting condition of a compressor comprises that the temperature of an evaporator is more than 2 ℃ and the ambient temperature is more than 5 ℃), the default refrigeration level is grade-1, the left-hand rotation of a temperature adjusting knob is grade-1, the refrigeration level is changed into grade-2, and the rest is done in a similar way, the refrigeration level is increased by grade-1 every time the temperature adjusting knob rotates for grade-1 leftwards until the refrigeration level reaches the maximum, and then the left-hand rotation refrigeration level is unchanged. The refrigeration level can be adjusted between-1 and-4 levels.

In the refrigeration state, if the right hand is rotated to 0 gear and +1 to +4 gear, the system exits the refrigeration mode, and the air conditioner naturally blows.

In a refrigerating state, if the heating starting piece is pressed, the system exits from a refrigerating mode and enters into a heating mode, the default heating level is +1 level, and the air volume is unchanged.

In a standby state, a heating starting piece is pressed, the air conditioner starts a heating mode, the default heating level is +1 level, the heating level is changed into +2 level by rotating the temperature adjusting knob in the 1 level rightwards, the heating level is increased by +1 level by rotating the temperature adjusting knob in the 1 level rightwards, until the heating level reaches the maximum, and then the right-rotating heating level is unchanged. The heating level can be adjusted between +1 and +4 levels.

In the heating state, if the left-hand rotation is carried out to the 0 gear and the-1 gear to the-4 gear, the heating function is quitted, and the air conditioner naturally blows.

In the heating state, if the refrigeration starting piece is pressed, the system exits the heating mode and enters the refrigeration mode, the default refrigeration level is-1 level, and the air volume is unchanged.

The above operation air volume is default to 3 grades, and the user can manually increase or decrease the air volume.

For the sake of understanding, the following will list the operation processes of the plurality of temperature adjusting knobs and the refrigeration and heating actuators, in these examples, the temperature adjusting knob is provided with 16 lines, the 16 lines are uniformly arranged on the temperature adjusting knob along the circumferential direction at intervals, and each rotation of one line represents the conversion of one gear. The middle part of the temperature adjusting knob is provided with two semicircular keys after being hollowed, and the two semicircular keys are respectively a refrigeration starting piece and a heating starting piece. On the circular temperature adjustment knob at the lowest part of fig. 12, the key with the snowflake pattern on the upper semicircle is the refrigeration starting piece, and the key with the sun pattern on the lower semicircle is the heating starting piece.

Example 1: as in fig. 13, in the standby state or in the natural wind mode, when the temperature adjustment knob is rotated right by one stage, the desired effect is to adjust the system to the heating mode of the +1 stage heating level, but since the heating start is not pressed, the operation determination is invalid and the system still maintains the natural wind blowing state. Then, when the temperature adjusting knob is rotated to the left for one gear, the expected effect is to turn off the heating mode of the +1 level heating level of the system, and the system still keeps the natural wind blowing state. This design is intended to avoid energy waste resulting from the passenger operating the temperature control too haphazardly, thereby avoiding a reduction in driving range.

Example 2: as shown in fig. 14, in the standby state or in the natural wind mode, when the temperature adjustment knob is rotated to the sixth gear right, the desired effect is to adjust the system to the heating mode of the maximum level heating level, but since the heating start is not pressed, the operation determination is invalid and the system still maintains the natural wind blowing state. Then, when the temperature adjusting knob is rotated to the left for six steps, the heating mode of the maximum heating level of the system is turned off, and the system still keeps the natural wind blowing state. This design is intended to avoid energy waste resulting from the passenger operating the temperature control too haphazardly, thereby avoiding a reduction in driving range.

Example 3: as shown in fig. 15, in the standby state or in the natural wind mode, when the temperature adjustment knob is rotated right by seven steps or more, the rotated angle exceeds the hot wind side starting step, the passenger's intention is clear, and the passenger's desired effect is the heating mode in which the system is adjusted to the maximum level of heating. At this time, the operation judgment is valid, and the system starts the heating mode at the maximum heating level. Because the maximum heating level of the system is 4 levels, the heating level is still kept at 4 levels when the temperature adjusting knob is rotated leftwards at a small angle, and the heating level is reduced after the temperature adjusting knob is rotated leftwards to +3 levels.

In addition, in a standby state, when the temperature adjusting knob is rotated to seven grades or more from 0 grade, the air outlet speed is 3 grades; in the natural wind mode, when the temperature adjusting knob is rotated rightwards for seven gears or more, the wind outlet speed is unchanged.

Example 4: as shown in fig. 16, when the passenger presses the heating starter in the standby state or in the natural wind mode, the system automatically defaults to turn on the heating mode at the minimum heating level. If the passenger wishes to increase the heating power, the temperature adjusting knob can be rotated right.

Example 5: in the heating mode, as shown in fig. 17, when the passenger presses the heating actuator, the system will turn off the heating mode and the system will keep the natural wind blowing.

Example 6: as shown in fig. 18, when the temperature adjustment knob is left-handed to the 0 th gear or the gear to the left of the 0 th gear in the heating mode, the heating mode is turned off.

In the heating mode, if the temperature adjusting knob is continuously rotated left and the gear on the left side of the 0-gear is rapidly reached, the heating mode is switched to the cooling mode, and the cooling level is the maximum level.

In addition, the wind speed remains unchanged after adjustment.
