Description

Technical Field

[0001] The present invention relates to the technical field of air supply equipment, and in particular to an air conditioner and a control method for the air conditioner. Background Art

[0002] Air conditioners have become an indispensable part of indoor cooling / heating appliances. With the arrival of autumn and winter, most consumers choose air conditioners as heating appliances. At present, the heat exchange form of air conditioners is mainly radiation heat exchange, so it has the advantages of comfort, silence, and no wind. However, due to the slow radiation heat exchange, the indoor temperature rises slowly, which makes it difficult to meet the user's comfort needs for a long time when the air conditioner is turned on. In addition, the air conditioner needs to blow out the cold air in the cavity before it can start heating at the beginning of heating, which causes the cold air to blow on people first after turning on the heating. In order to reduce the duration of cold air, blow out hot air quickly, and improve the user experience of the product, electric auxiliary heating devices are installed inside the air conditioner. In the early stage of heating, the air conditioner is assisted to heat the air, reduce the duration of cold air blowing, and improve user satisfaction.

[0003] In the prior art, the electric auxiliary heating device inside the traditional air conditioner is fixed in position and installed in the space formed by the air duct component and the outer shell. It is in working state to assist in heating the air in the initial stage of heating. In the initial stage of cooling or non-heating, the electric auxiliary heating device is in a non-working state. The indoor air enters from the air inlet, and part of it passes through the air duct and then passes through the evaporator and is blown out from the air outlet. Part of the indoor air passes through the air duct and then passes through the evaporator and is blown out from the air outlet after the electric auxiliary heating. Due to the existence of electric auxiliary heating, the air volume blown out of the air conditioner in the initial stage of cooling or non-heating is reduced, resulting in poor user experience.

[0133] It should be noted that the upper volute tongue motion mechanism and the lower volute tongue motion mechanism in the embodiment of the present invention are based on mature mechanisms and will not be described in detail in the embodiment of the present invention.

[0134] Specifically, the cooling mode of the air conditioner includes a single upper air outlet cooling mode and a simultaneous upper and lower air outlet cooling mode, and the heating mode of the air conditioner includes a single lower air outlet heating mode and a simultaneous upper and lower air outlet heating mode. When the air conditioner operates in the single upper air outlet cooling mode and the simultaneous upper and lower air outlet cooling mode, the heating structure is controlled to move to the avoidance position; when the air conditioner operates in the single lower air outlet heating mode and the simultaneous upper and lower air outlet heating mode, the heating structure is controlled to move to the heating position.

[0135] Of course, the air conditioner in the present invention is not limited to the above-mentioned several operating modes. In the embodiment of the present invention, the above-mentioned several operating modes are taken as examples to illustrate the working principle of the air conditioner in the embodiment of the present invention. In detail:

[0136] like Figure 5 and Figure 6 As shown, when the air conditioner operates in the single upper air outlet cooling mode, the upper wind shield structure 81 is controlled to rotate to close the upper return air outlet 2111, at which time the upper fan duct 22 is connected to the first upper air outlet 211, the upper wind shield structure 82 is controlled to rotate to connect the middle air duct 23 and the second upper air outlet 212, the upper volute tongue movement mechanism 41 is controlled to move to the first position to allow the upper fan 4 to discharge air upward, the lower wind shield structure 83 is controlled to rotate to open the lower return air outlet 2511, at which time the lower fan duct 24 is not connected to the first lower air outlet 251, the lower wind shield structure 84 is controlled to rotate to block the connection between the second lower air outlet 252 and the middle air duct 23, and the lower volute tongue movement mechanism 51 is controlled to move to the third position to allow the lower fan 5 to discharge air upward; at this time, the indoor air flows from the third vent 13 at the bottom of the air conditioner through the lower return air outlet 25 11 enters into the body shell channel 3, and the other part of the wind enters into the body shell channel 3 through the second vent 12 at the top of the air conditioner and the fourth vent 14 at the bottom of the air conditioner. The wind entering into the body shell channel 3 will flow to the opposite sides of the shell 1. Under the action of the upper fan 4, part of the wind passes through the heat exchanger assembly 9 and the heating structure 100 and enters into the cavity of the upper fan 4 from the axial direction of the upper fan 4. Under the action of the upper fan 4, it passes through the first upper air outlet 211 and is finally blown out from the first vent 11 at the top of the air conditioner. Under the action of the lower fan 5, another part of the wind passes through the heat exchanger assembly 9 and the heating structure 100 and enters into the cavity of the lower fan 5 from the axial direction of the lower fan 5. Under the action of the lower fan 5, it passes through the middle air duct 23 and the second upper air outlet 212 and is finally blown out from the first vent 11 at the top of the air conditioner.

[0137] like Figure 3 and Figure 4As shown, when the air conditioner runs in a single downward air outlet heating mode, the upper wind shield structure 81 is controlled to rotate to open the upper return air outlet 2111. At this time, the upper fan duct 22 and the first upper air outlet duct 211 are not connected. The upper wind shield structure 82 is controlled to rotate to block the connection between the middle air duct 23 and the second upper air outlet duct 212. The upper volute tongue movement mechanism 41 is controlled to move to the second position to allow the upper fan 4 to discharge air downward. The lower wind shield structure 83 is controlled to rotate to close the lower return air outlet 2511. At this time, the lower fan duct 24 is connected to the first lower air outlet duct 251. The lower wind shield structure 84 is controlled to rotate to connect the second lower air outlet duct 252 and the middle air duct 23. The lower volute tongue movement mechanism 51 is controlled to move to the fourth position to allow the lower fan 5 to discharge air downward. The return air port 2111 enters into the body shell channel 3, and the other part of the wind enters into the body shell channel 3 through the second vent 12 at the top of the air conditioner and the fourth vent 14 at the bottom of the air conditioner. The wind entering into the body shell channel 3 will flow to the opposite sides of the shell 1. Under the action of the down fan, part of the wind passes through the heat exchanger assembly 9 and the heating structure from the axial direction into the cavity of the down fan 5, and under the action of the down fan 5, passes through the first down air outlet 251 and is finally blown out from the third vent 13 at the bottom of the air conditioner. Under the action of the up fan 4, another part of the wind passes through the heat exchanger assembly 9 and the heating structure from the axial direction into the cavity of the up fan 4, and under the action of the up fan, passes through the middle air duct 23 and the second down air outlet 252 and is finally blown out from the third vent 13 at the bottom of the air conditioner.

[0138] like Figure 7As shown, when the air conditioner is running in the cooling or heating mode with air flowing out from top and bottom at the same time, the upper wind shield structure 81 is controlled to rotate to close the upper return air outlet 2111, at which time the upper fan duct 22 is connected to the first upper air outlet 211, the upper wind shield structure 82 is controlled to rotate to block the connection between the middle air duct 23 and the second upper air outlet 212, the upper volute tongue movement mechanism 41 is controlled to move to the first position to allow the upper fan 4 to discharge air upward, the lower wind shield structure 83 is controlled to rotate to close the lower return air outlet 2511, at which time the lower fan duct 24 is connected to the first lower air outlet 251, the lower wind shield structure 84 is controlled to rotate to block the connection between the middle air duct 23 and the second lower air outlet 252, and the lower volute tongue movement mechanism 51 is controlled to move to the fourth position to allow the lower fan 5 to discharge air downward. At this time, the indoor air enters the body shell channel 3 from the second vent 12 at the top of the air conditioner and the fourth vent 14 at the bottom of the air conditioner. The wind entering the body shell channel 3 will flow to the opposite sides of the body. Under the action of the down fan 5, part of the wind passes through the heat exchanger assembly 9 and the heating structure 100 from the axial direction of the down fan 5 and enters the cavity of the down fan 5. Under the action of the down fan 5, it passes through the first lower air outlet 251 and is finally blown out from the third vent 13 at the bottom of the air conditioner. Another part of the wind passes through the heat exchanger assembly 9 and the heating structure 100 from the axial direction of the upper fan 4 and enters the cavity of the upper fan 4 through the first upper air outlet 211 under the action of the upper fan 4 and is finally blown out from the first vent 11 at the top of the air conditioner.

[0139] It can be seen that the air inlet and outlet positions of the air conditioner in the embodiment of the present invention vary with the different air outlet modes. In the cooling mode, the third vent 13 located at the lower part of the air conditioner is switched to the air inlet, realizing bottom-in and top-out; in the heating mode, the first vent 11 located at the upper part of the air conditioner is switched to the air inlet, realizing top-in and bottom-out, and the air inlet and outlet are switched according to the different modes.

[0140] By arranging the heating structure 100 in the air conditioner, the air conditioner can realize different air inlet and outlet modes under different working conditions and different temperatures. Under the same working condition and the same temperature, the air conditioner can realize the air inlet and outlet mode with large air volume.

[0141] It is worth mentioning that the reason why the heating structure 100 in the embodiment of the present invention is arranged in the middle position of the heat exchanger assembly is also based on the air outlet mode of the air conditioner in this embodiment. As can be seen from the above, the air conditioner in the embodiment of the present invention can realize both upper air inlet and lower air outlet, and lower air inlet and upper air outlet, that is, the air conditioner in the embodiment of the present invention is an up and down reversible air outlet air conditioner. Based on this, by setting the heating structure 100 in the middle position of the heat exchanger assembly 9, no matter whether the air conditioner is operating with upper air inlet, lower air outlet or lower air inlet and upper air outlet, the heating structure arranged inside the air conditioner can exchange heat with the air. If the position of the heating structure is set to the upper or lower position in the middle, the heat exchange efficiency between the heating structure 100 and the air cannot be maximized.

[0142] Further, at least one of the upper windshield structure 1 81, the upper windshield structure 2 82, the lower windshield structure 1 83 and the lower windshield structure 2 84 is connected to the heating structure 100 by transmission;

[0143] When the air conditioner operates in the upper air outlet cooling mode or the upper and lower air outlet cooling mode, the heating structure 100 can be connected to at least one of the upper wind shielding structure 1 81, the upper wind shielding structure 2 82, the lower wind shielding structure 1 83 and the lower wind shielding structure 2 84 to move to the avoidance position;

[0144] When the air conditioner operates in a single bottom air outlet heating mode or a top and bottom air outlet heating mode, the heating structure 100 can be transmission-connected with at least one of the upper wind shield structure 1 81 , the upper wind shield structure 2 82 , the lower wind shield structure 1 83 and the lower wind shield structure 2 84 to move to the heating position.

[0145] That is, the heating structure in the embodiment of the present invention can be linked with the wind shield structure in the air conditioner, thereby eliminating the setting of the drive motor and reducing the production cost. Specifically, the linkage between the heating structure 100 and the baffle structure can be achieved through transmission mechanisms such as connecting rod mechanisms and gear mechanisms. The specific transmission structure form is not specifically described in the embodiment of the present invention.

[0146] Preferably, the upper wind shield structure 1 81, the upper wind shield structure 2 82, the lower wind shield structure 1 83, and the lower wind shield structure 2 84 can all be configured as baffles.

[0147] In any of the above embodiments, when the air conditioner operates in a single upper air outlet cooling mode, the upper volute tongue motion mechanism 41 and the upper wind shield structure 1 81 constitute a part of the volute profile of the upper fan 4, and the lower volute tongue motion mechanism 51, the lower partition 7 and the lower wind shield structure 2 84 constitute a part of the volute profile of the lower fan 5;

[0148] When the air conditioner operates in a single downward air outlet heating mode, the upper volute tongue movement mechanism 41, the upper partition 6 and the upper wind shield structure 2 82 constitute a part of the volute profile of the upper fan 4, and the lower volute tongue movement mechanism 51 and the lower wind shield structure 1 83 constitute a part of the volute profile of the lower fan 5;

[0149] When the air conditioner operates in cooling or heating mode with air blowing from both top and bottom, the upper volute tongue movement mechanism 41 and the upper wind shield structure 81 constitute a part of the volute profile of the upper fan 4, and the lower volute tongue movement mechanism 51 and the lower wind shield structure 83 constitute a part of the volute profile of the lower fan 5.

[0150] Since centrifugal fans make louder noise than other types of fans during operation, in an embodiment of the present invention, the volute tongue motion mechanism {upper volute tongue motion mechanism and lower volute tongue motion mechanism} and partitions {upper partition and lower partition}, and wind shield structures {upper wind shield structure one, upper wind shield structure two, lower wind shield structure one and lower wind shield structure two} are combined and matched in different operating modes to form the profile of the air duct. In this way, when the air conditioner is running, the noise generated by the air conditioner during operation can be reduced.

[0151] Specifically, Fig.11 As shown, the upper partition 6 includes an upper triangular block provided in the upper air outlet duct 21, and the lower partition 7 includes a lower triangular block provided in the lower air outlet duct 25;

[0152] The upper triangular stopper includes a first upper side 61, a second upper side 62 and a third upper side 63 which are connected in sequence, the first upper side 61 constituting at least a portion of the air duct wall of the first upper air outlet 211, the second upper side 62 constituting at least a portion of the air duct wall of the second upper air outlet 212, and the third upper side 63 being arranged close to the upper fan 4;

[0153] The lower triangular stopper includes a first lower side 71, a second lower side 72 and a third lower side 73 connected in sequence, the first lower side 71 constitutes at least part of the air duct wall of the first lower air outlet 251, the second lower side 72 constitutes at least part of the air duct wall of the second lower air outlet 252, and the third lower side 73 is arranged close to the lower fan 5; wherein;

[0154] When the air conditioner operates in the single upper air outlet cooling mode, the lower volute tongue movement mechanism 51, the third lower side edge 73 and the lower wind shielding structure 2 84 constitute a part of the volute profile of the lower fan 5;

[0155] When the air conditioner operates in a single downward air outlet heating mode, the upper volute tongue movement mechanism 41 , the third upper side edge 63 and the second upper wind shielding structure 82 constitute a part of the volute profile of the upper fan 4 .

[0156] Of course, in some alternative embodiments, the upper separator 6 and the lower separator 7 are not limited to the triangular stopper, as long as the separator {upper separator and lower separator} can achieve the above functions. Of course, in the embodiment of the present invention, it is preferred that the upper separator 6 and the lower separator 7 are both set as triangular stoppers.

[0157] like Fig.12 As shown, in order to further reduce the noise generated by the air conditioner during operation, in the embodiment of the present invention, the third upper side 63 disposed close to the upper fan 4 is configured as an arc, and the third lower side 73 disposed close to the lower fan 5 is configured as an arc;

[0158] The upper wind shield structure 1 81 , the upper wind shield structure 2 82 , the lower wind shield structure 1 83 and the lower wind shield structure 2 84 are all constructed in an arc shape.

[0159] In this way, when the air conditioner is operating in different operating modes, the volute tongue motion mechanism {upper volute tongue motion mechanism and lower volute tongue motion mechanism} and the partition {upper partition and lower partition} and the wind shield structure {upper wind shield structure one, upper wind shield structure two, lower wind shield structure one and lower wind shield structure two} are combined to form the profile of the air duct to form a continuous arc curve, thereby further reducing wind noise.

[0160] In any of the above embodiments, if Figure 2 As shown, the air conditioner further includes an upper channel 300 and a lower channel 200;

[0161] The lower end of the upper channel 300 is connected to the upper air outlet 21, and the upper end is connected to the first vent 11;

[0162] The upper end of the lower channel 200 is connected to the lower air outlet 25, and the lower end is connected to the third vent 13;

[0163] The housing 1 also includes:

[0164] The air inlet component 1a has an open front and upper portion and an accommodating space formed therein;

[0165] The panel component 1b is installed at an open position in front of the air inlet component 1a;

[0166] A top cover component 1c, the top cover component 1c is installed at an open position on the upper part of the air inlet component 1a;

[0167] A base component 1d, the base component 1d is installed at the lower part of the air inlet component 1a;

[0168] A first vent 11 and a second vent 12 with upward openings are defined between the air inlet component 1a, the top cover component 1c and the panel component 1b, and a third vent 13 with an opening direction facing forward and a fourth vent 14 with an opening direction facing downward are defined between the air inlet component 1a, the base component 1d and the panel component 1b.

[0169] like Fig.13 As shown, the second aspect of the embodiment of the present invention further provides a control method for an air conditioner, wherein the air conditioner includes a casing, a ventilation duct is formed in the casing, a heating structure is provided on the ventilation duct, and the heating structure is movably arranged on the ventilation duct, and the control method includes:

[0170] Acquire the air outlet mode and / or operation mode of the air conditioner and / or the indoor temperature of the air conditioner and / or the indoor humidity of the air conditioner;

[0171] The working state of the heating structure and / or the position of the heating structure in the ventilation duct is controlled according to the air outlet mode and / or the operation mode of the air conditioner and / or the indoor temperature of the air conditioner and / or the indoor humidity of the air conditioner.

[0172] Specifically, the air outlet mode of the air conditioner includes an upper air inlet and lower air outlet mode, an upper air outlet and lower air inlet mode, and an upper and lower air outlet mode; the operation mode of the air conditioner includes a heating mode and a cooling mode;

[0173] Wherein controlling the working state of the heating structure and / or the position of the heating structure in the ventilation duct according to the air outlet mode and / or the operation mode of the air conditioner and / or the indoor temperature of the air conditioner and / or the indoor humidity of the air conditioner includes:

[0174] When the air conditioner is in cooling mode, and the air outlet mode is in upper outlet and lower inlet mode or upper and lower outlet mode, the heating structure is controlled to be turned off and moved to a avoiding position to avoid the airflow in the ventilation duct;

[0175] When the air conditioner operation mode is heating mode, and the air outlet mode of the air conditioner is upper air inlet and lower air outlet mode or upper and lower simultaneous air outlet mode, the heating structure is controlled to turn on and move to a heating position to heat the airflow in the ventilation channel.

[0176] It is worth noting that the air conditioner in the air conditioner control method provided in the second aspect of the embodiment of the present invention may include a heating structure that is the same as the heating structure provided in the first aspect of the embodiment of the present invention, and its positional relationship, connection relationship and connection method with the air duct component may also be the same as those in the first aspect of the embodiment. At the same time, when the heating structure in the air conditioner provided in the second aspect of the embodiment of the present invention adjusts its heating position according to the air outlet method of the air conditioner, it may also be adjusted in the same way as the air conditioner in the first aspect of the above-mentioned embodiment.

[0177] The difference is that the heating structure in the air conditioner provided in the second aspect of the embodiment of the present invention can also adjust the position and working state of the heating structure according to the indoor temperature and humidity:

[0178] Specifically, when the indoor temperature is lower than the first temperature range, the heating structure is controlled to turn on and move to a heating position for heating the airflow in the ventilation duct; and / or

[0179] When the indoor temperature is higher than or equal to the first temperature range, the heating structure is controlled to be turned off and moved to a avoidance position to avoid the airflow in the ventilation duct; and / or

[0180] When the indoor humidity is higher than a first humidity interval and the indoor temperature is lower than a first temperature threshold interval, the heating structure is controlled to turn on and move to a heating position for heating the airflow in the ventilation duct; and / or

[0181] When the indoor humidity is higher than the first humidity range and the indoor temperature is within the first temperature range, the heating structure is controlled to turn on and move to a heating position for heating the airflow in the ventilation duct; and / or

[0182] When the indoor humidity is lower than or equal to the first humidity range and the indoor temperature is higher than or equal to the first temperature range, the heating structure is controlled to be closed and moved to a avoidance position to avoid the airflow in the ventilation duct.

[0183] More specifically, when the temperature sensor inside the air conditioner detects that the indoor temperature is lower than the first temperature range, the temperature sensor converts the detection signal to control the gear in the heating structure to rotate and operate the heating structure, and at this time, the heat exchange surface of the heating structure and the outer wall surface of the air duct component in the casing are in a vertical state of approximately 90 degrees;

[0184] When the temperature sensor inside the air conditioner detects that the indoor temperature is higher than the first temperature range, the temperature sensor converts the detection signal to control the gear in the heating structure to rotate and turn off the heating structure. At this time, the heat exchange surface of the heating structure is parallel to the outer wall surface of the air duct component in the casing.

[0185] When the humidity sensor inside the air conditioner detects that the indoor humidity is higher than the first humidity range and the indoor temperature is lower than the first temperature range, the humidity sensor converts the detection signal to control the rotation of the gears in the heating structure and turn on the heating structure. At this time, the heat exchange surface of the heating structure and the outer wall surface of the air duct component in the casing are approximately 90 degrees vertical, and the heating structure is operated in the heating and dehumidification mode to complete the dehumidification of the air and increase the temperature.

[0186] When the humidity sensor inside the air conditioner detects that the indoor humidity is higher than the first humidity range and the indoor temperature is within the first temperature range, the humidity sensor converts the detection signal to control the gears in the heating structure to open and operate the heating structure. At this time, the heat exchange surface of the heating structure and the outer wall surface of the air duct component in the casing are in a vertical state of approximately 90 degrees, and the electric auxiliary heating temperature control dehumidification mode is operated to complete the dehumidification of the air and maintain the temperature.

[0187] When the humidity sensor inside the air conditioner detects that the indoor humidity is lower than or equal to the first humidity range and the temperature is higher than or equal to the first temperature range, the humidity sensor converts the detection signal to control the gear in the heating structure to open and operate the heating structure, at which time the heat exchange surface of the heating structure is parallel to the outer wall surface of the air duct component in the casing and the operation of the heating structure is turned off;

[0188] The first temperature range is {5°-18°}, and the first humidity range is {50%-70%}.

[0189] As described above, in the control method of the air conditioner provided in the second aspect of the embodiment of the present invention, the operating state of the heating structure can be controlled and converted according to the indoor temperature and / or indoor humidity. Specifically, the control of the heating structure by temperature is a separate control, that is, when the temperature reaches the set value, the state of the heating structure is directly controlled regardless of the humidity; the control of the heating structure by humidity must be tested by temperature to determine whether it controls the state of electric auxiliary heating. When the temperature is very high, even if the humidity is very high, the electric heating structure is not turned on, and the air conditioner is in cooling and dehumidification mode; when the temperature is within the set value range, when the humidity exceeds the preset value, the electric heating structure is controlled to turn on for temperature control and dehumidification, and while completing dehumidification, it is ensured that the temperature does not rise.
