Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment, and particularly relates to a refrigeration device. Background Technology

[0002] With the development of air conditioning technology, people have higher requirements for the comfort of air delivery and on-demand temperature distribution. However, in related technologies, air conditioners lack targeted improvements in duct design and air delivery methods. Traditional air conditioner duct designs easily lead to vortices or turbulence within the duct, which not only reduces the airflow but may also cause uneven indoor temperature distribution. Furthermore, traditional air conditioners typically adjust the airflow based solely on the ambient temperature and the user-set temperature; this direct-blowing airflow method may affect user comfort and overall experience. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the related art. To this end, this application proposes a cooling device that can improve temperature uniformity by adding an auxiliary air duct below the main air duct. The auxiliary air duct provides additional circulating air volume by increasing the negative pressure at the air outlet. Furthermore, by adding the auxiliary air duct, the airflow field at the outlet of the cooling device can be changed, thereby simulating natural wind and improving user comfort and experience.

[0004] In a first aspect, this application provides a refrigeration device, comprising:

[0005] The main fan is used to drive the airflow within the refrigeration equipment; the main fan is a cross-flow fan.

[0006] The main air duct is located between the main fan and the main air outlet of the refrigeration equipment;

[0007] The first air guide plate is located at the main air outlet;

[0008] An auxiliary air duct connects the main air duct and the auxiliary air outlet;

[0009] An auxiliary fan is installed in the auxiliary air duct and is used to drive the air in the main air duct to flow towards the auxiliary air outlet.

[0010] An indoor temperature sensor is used to obtain the ambient temperature of the environment in which the refrigeration equipment is located when the refrigeration equipment is turned on.

[0011] The controller is used to adjust at least one of the main fan speed and the opening angle of the first air guide plate based on at least one of the ambient temperature and user input, and to adjust the opening and closing state of the auxiliary fan.

[0012] According to the refrigeration equipment of this application, by using a main air duct and an auxiliary air duct connected to the main air duct, the circulating air volume of the refrigeration equipment can be increased, thereby improving temperature uniformity. On this basis, the ambient temperature of the environment in which the refrigeration equipment is located can be obtained based on an indoor temperature sensor and a controller, and the refrigeration equipment can be controlled to enter a corresponding working mode based on at least one of the ambient temperature or a first input from the user. This can realize the change of the air field of the refrigeration equipment outlet, taking into account the operation mode of the refrigeration equipment from multiple perspectives from the user's point of view, thereby achieving the effect of simulating natural wind in the refrigeration equipment and improving user comfort and experience.

[0013] According to one embodiment of this application, the controller is configured to control the auxiliary fan to turn on upon receiving a first input from a user; and to adjust the speed of the main fan and the opening angle of the first air guide plate based on the ambient temperature and a first set temperature.

[0014] According to the refrigeration device of this application, upon receiving a first input from a user, the auxiliary fan is turned on while the main fan speed and the opening angle of the first air guide plate are adjusted based on the ambient temperature and a first set temperature. This adjusts the working state of the main air duct to enhance the effect of the auxiliary air duct and the main air duct jointly simulating natural wind.

[0015] According to one embodiment of this application, the controller is used to control the main fan to rotate at maximum speed and / or adjust the opening of the first air guide plate to the maximum angle when the absolute value of the difference between the ambient temperature and the first set temperature is greater than a first threshold.

[0016] If the absolute value of the difference between the ambient temperature and the first set temperature is not greater than the first threshold, the speed of the main fan is automatically adjusted based on the first set temperature, and / or the opening angle of the first air guide plate is adjusted to cycle between the maximum angle and the minimum angle.

[0017] According to the cooling device of this application, the main fan speed and the opening angle of the first air guide plate are adjusted based on the ambient temperature and the first set temperature. This can improve the user's comfort experience while satisfying the requirement to lower or raise the ambient temperature.

[0018] According to one embodiment of this application, the controller is further configured to:

[0019] After the auxiliary fan is turned on, if a second input from the user is received, the auxiliary fan is turned off in response to the second input, and the speed of the main fan is automatically adjusted based on the first set temperature.

[0020] According to the cooling device of this application, by controlling the auxiliary fan to turn off when the user manually exits the natural wind mode, and automatically adjusting the speed of the main fan based on the first set temperature, the user can have a comfortable transition when the cooling device switches from natural wind mode to regular air outlet mode, thus improving the user experience.

[0021] According to one embodiment of this application, the controller is further configured to:

[0022] Upon receiving a third input from the user, and with the auxiliary fan turned on, the speed of the main fan is reduced, and / or the opening angle of the first air guide plate is adjusted to cycle between the maximum and minimum angles.

[0023] According to the refrigeration equipment of this application, when the user turns on the device and enters the normal air outlet mode, and the refrigeration equipment subsequently enters the natural wind mode after running in the normal air outlet mode for a period of time, the main air outlet can be gently vented by reducing the speed of the main fan or adjusting the first air guide plate to be in an up-and-down sweeping state, thereby improving user comfort.

[0024] According to one embodiment of this application, the controller is further configured to:

[0025] After receiving the user's third input, if the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the auxiliary fan is controlled to turn on.

[0026] or,

[0027] Receive the user's fourth input;

[0028] In response to the fourth input, the auxiliary fan is controlled to turn on.

[0029] According to the cooling device of this application, after the user turns on the device without entering the natural wind mode, but when the absolute value of the difference between the ambient temperature and the second set temperature is less than a second threshold, the auxiliary fan is controlled to turn on, so as to simulate the comfortable airflow of natural wind when the difference between the ambient temperature and the second set temperature is small, thereby improving the user's comfort and experience. Furthermore, by controlling the auxiliary fan to turn on in multiple ways, such as based on the difference between the ambient temperature and the set temperature or by the user manually setting the natural wind mode, the control of the cooling device to enter the natural wind mode can be diversified, thereby improving the user experience.

[0030] According to one embodiment of this application, the controller is further configured to:

[0031] After the auxiliary fan is turned on, if the absolute value of the difference between the ambient temperature and the second set temperature is greater than a third threshold, the auxiliary fan is controlled to turn off.

[0032] or,

[0033] Receive the user's fifth input;

[0034] In response to the fifth input, the auxiliary fan is controlled to turn off.

[0035] According to the cooling device of this application, by controlling whether the auxiliary fan enters the off state based on the difference between the ambient temperature and the set temperature, the problem of the ambient temperature rising affecting the user experience in natural wind mode can be reduced, thereby improving the user experience and comfort. Furthermore, by controlling the auxiliary fan to turn off based on the difference between the ambient temperature and the set temperature or by the user manually exiting the natural wind mode, the control of the cooling device exiting the natural wind mode can be diversified, thereby improving the user experience.

[0036] According to one embodiment of this application, the controller is further configured to:

[0037] While the auxiliary fan is on, if the controller reduces the speed of the main fan, then after the auxiliary fan is turned off, it controls the speed of the main fan to increase.

[0038] According to the refrigeration equipment of this application, by controlling the main fan speed to increase while the main fan speed is reduced during the auxiliary fan's operation after the auxiliary fan is turned off, the main fan speed can be readjusted to the state before the auxiliary fan was turned on. This facilitates the adjustment of the main fan speed when the auxiliary fan is turned on again, enhances the controller's control logic, and thus improves the stability and safety of the refrigeration equipment.

[0039] According to one embodiment of this application, it further includes: a sliding air guide plate disposed at the auxiliary air outlet;

[0040] The controller is also used to control the sliding air guide plate to slide laterally along the auxiliary air outlet when the auxiliary fan is turned on.

[0041] According to the refrigeration equipment of this application, by setting a sliding air guide plate at the auxiliary air outlet, the air guide plate can be continuously circulated and laterally slid along the auxiliary air outlet to realize the change of wind field, thereby realizing the simulation of natural wind.

[0042] According to one embodiment of this application, the auxiliary fan includes a plurality of centrifugal fans;

[0043] The controller is used to control the target centrifugal fan among the plurality of centrifugal fans to remain constantly on when the auxiliary fan is turned on, and to control the other centrifugal fans among the plurality of centrifugal fans, excluding the target centrifugal fan, to turn on intermittently.

[0044] According to the refrigeration equipment of this application, by setting multiple centrifugal fans in the auxiliary air duct and setting some centrifugal fans to be constantly on and some centrifugal fans to be intermittently on, the function of the sliding air guide plate to continuously slide laterally along the auxiliary air outlet can be replaced to achieve natural wind simulation.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0062] In the description of this application, it should be understood that the terms "upper", "lower", "inner", "outer", "left" or "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] The refrigeration equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0064] This application provides a refrigeration device.

[0065] In this embodiment, the refrigeration equipment can be understood as a refrigeration equipment in a broad sense, including but not limited to air conditioners, air conditioning fans, refrigeration units, and evaporative coolers. Refrigeration equipment has diverse structural forms and a wide range of applications; among them, air conditioners can include wall-mounted air conditioners, floor-standing air conditioners, central air conditioners, and window air conditioners.

[0066] like Figure 6 As shown, the refrigeration equipment may include: a housing 610, an indoor heat exchanger, a base 620, a heat exchange fan, an outdoor four-way valve, an outdoor compressor, an outdoor condenser, a throttling device, and a user interface, etc.

[0067] The housing 610 is the outer shell of the indoor unit of the refrigeration equipment. The housing 610 has an internal cavity and a heat exchange air inlet and a heat exchange air outlet. In the height direction of the refrigeration equipment, the heat exchange air inlet is located above the heat exchange air outlet.

[0068] The indoor heat exchanger is the evaporator of the refrigeration equipment and is located inside the containment cavity.

[0069] The base 620 is the base of the indoor unit of the refrigeration equipment. In the height direction of the refrigeration equipment, the base 620 is located at the bottom of the accommodating cavity.

[0070] The heat exchange fan is a fan installed inside the containment cavity, used to blow the heat-exchanged air out from the heat exchange outlet.

[0071] The outdoor four-way valve, located inside the outdoor unit, is used to switch the refrigerant flow direction in cooling / heating modes.

[0072] The outdoor compressor, located inside the outdoor unit, is used to maintain the pressure difference and drive the refrigerant circulation.

[0073] The outdoor condenser is located inside the outdoor unit and is used for heat exchange in either cooling or heating mode.

[0074] The throttling device, located inside the outdoor unit, is used to regulate the refrigerant flow and control the pressure and temperature.

[0075] The user interface can be an interactive interface set on the refrigeration equipment to receive user input commands and provide interaction between the user and the refrigeration equipment.

[0076] In actual operation, users can input commands to turn on the cooling equipment through the user interface. After the cooling equipment enters the working state, users can set the cooling / heating mode and set the set temperature through the user interface.

[0077] In the cooling mode of the refrigeration equipment, the compressor starts and compresses the refrigerant into a high-pressure saturated gas (ammonia or Freon). This gaseous refrigerant is then condensed by the condenser, throttled by the throttling device, and then introduced into the evaporator. It absorbs the heat of the indoor air entering the containment chamber through the heat exchange inlet, causing the air temperature to drop. The heat exchange fan of the indoor unit blows the cooled air out of the heat exchange outlet, achieving indoor cooling. The evaporated low-pressure refrigerant returns to the compressor and restarts the cycle until the indoor temperature is approximately equal to the set temperature.

[0078] In the heating mode of the refrigeration equipment, the compressor starts and compresses the refrigerant into a high-pressure saturated gas (ammonia or Freon). The four-way valve switches the refrigerant flow to the indoor evaporator. The refrigerant releases heat in the indoor unit's evaporator, heating the indoor air entering the containment cavity through the heat exchange air inlet. The indoor unit's heat exchange fan blows the heated air out of the heat exchange air outlet, thus raising the indoor temperature. The refrigerant absorbs heat in the outdoor unit's condenser, changing from a gaseous state to a high-pressure liquid state. After the liquid refrigerant passes through the throttling device, its pressure decreases, and the low-pressure refrigerant returns to the compressor, restarting the cycle until the indoor temperature is approximately equal to the set temperature.

[0079] like Figure 5 and Figure 7 As shown, the refrigeration equipment also includes a main fan 710, a main air duct 720, a first air guide plate 7211, an auxiliary fan 730, an auxiliary air duct 740, an indoor temperature sensor 510, and a controller 520.

[0080] In this embodiment, the main air duct 720 is the main air outlet duct of the refrigeration equipment, and is located between the main fan 710 and the main air outlet 721 of the refrigeration equipment.

[0081] The main fan 710 is a cross-flow fan installed in the main air duct 720, used to drive the airflow within the refrigeration equipment and blow the heat-exchanged air out from the main air outlet 721. For example... Figure 6 As shown, the main air outlet 721 is located on the housing 610, and a first air guide plate 7211 is provided at the main air outlet 721.

[0082] The first air guide plate 7211 is disposed at the main air outlet 721 and is rotatably connected to the housing 610 at the main air outlet 721. It is used to adjust the air outlet angle of the main air outlet 721. In actual operation, the first air guide plate 7211 can rotate from the inside to the outside to open the main air outlet 721, or it can rotate from the outside to the inside to close the main air outlet 721.

[0083] The auxiliary air duct 740 is an auxiliary air outlet duct located below the main air duct 720 in the height direction of the refrigeration equipment, and connects the main air duct 720 and the auxiliary air outlet 741.

[0084] An auxiliary fan 730 is installed in the auxiliary air duct 740 to drive the air in the main air duct 720 to flow towards the auxiliary air outlet 741, thereby blowing the heat-exchanged air out from the auxiliary air outlet 741.

[0085] The auxiliary fan 730 and the auxiliary air duct 740 are turned on or started simultaneously; it can be understood that when the auxiliary fan 730 is turned on, the auxiliary air duct 740 is also turned on.

[0086] It should be noted that when the main fan 710 is on, the auxiliary air duct 740 can be opened and closed independently.

[0087] The indoor temperature sensor 510 is electrically connected to the controller 520 and is used to collect indoor temperature data.

[0088] The controller 520 can be electrically connected to the drive motors of the main fan 710, the auxiliary fan 730 and the first air guide plate 7211 respectively, and is used to control the main fan 710, the auxiliary fan 730 and the first air guide plate 7211.

[0089] The processing logic of the indoor temperature sensor 510 and the controller 520 will be explained below.

[0090] The indoor temperature sensor 510 and controller 520 can be used to perform processes such as Figure 1 The control method of the refrigeration equipment shown.

[0091] like Figure 1 As shown, the indoor temperature sensor 510 is used to perform step 110, that is, to obtain the ambient temperature of the environment in which the cooling equipment is located when the cooling equipment is turned on; the controller 520 is used to perform step 120, that is, to adjust at least one of the main fan speed 710 and the opening angle of the first air guide plate 7211 based on at least one of the ambient temperature and user input, and to adjust the opening and closing state of the auxiliary fan 730.

[0092] In step 110, the environment in which the refrigeration equipment is located can be understood as the spatial range served by the refrigeration equipment during its working state.

[0093] For example, taking air conditioners as a type of refrigeration equipment, the environment in which an air conditioner is located can include a family bedroom, living room, or a studio, meeting room, or work hall.

[0094] The ambient temperature can be the actual temperature of the space served by the refrigeration equipment when it is in operation; that is, the ambient temperature can be a changing temperature.

[0095] For example, taking air conditioners as a type of refrigeration equipment, the ambient temperature of the environment in which the air conditioner is located can include the indoor temperature of a family bedroom, the indoor temperature of a living room, etc.

[0096] In step 120, the user's input is used to determine whether to activate the natural wind mode.

[0097] The operating modes of refrigeration equipment can include natural wind mode and conventional air outlet mode.

[0098] The natural wind mode can simulate the airflow pattern of natural wind for the cooling equipment; when the natural wind mode is not activated, the cooling equipment operates based on the normal airflow pattern.

[0099] It is understandable that the speed of the main fan 710, the opening angle of the first air guide plate 7211, and the opening and closing state of the auxiliary fan 730 may be different in different working modes of the refrigeration equipment; among them, the opening and closing state of the auxiliary fan 730 may include an on state and a closed state.

[0100] Of course, under the same working mode, the speed of the main fan 710, the opening angle of the first air guide plate 7211, and the opening and closing state of the auxiliary fan 730 may be different depending on the changes in ambient temperature.

[0101] During the research and development process, the inventors discovered that the duct design of traditional air conditioners is prone to causing vortices or turbulence inside the duct. This not only reduces the air circulation volume of the air conditioner, but may also lead to uneven indoor temperature distribution. In addition, traditional air conditioners usually adjust the air output only according to the ambient temperature and the temperature set by the user. This direct air output method may affect the user's comfort and thus affect the user's experience.

[0102] In the above embodiments, by using a cooling device that includes a main air duct 720 and an auxiliary air duct 740 connected to the main air duct 720, with a main fan 710 installed in the main air duct 720 and an auxiliary fan 730 installed in the auxiliary air duct 740, the circulating air volume of the cooling device can be increased, thereby improving temperature uniformity. On this basis, based on the indoor temperature sensor 510 and the controller 520, the ambient temperature of the environment in which the cooling device is located is obtained, and based on at least one of the ambient temperature or the user's first input, the cooling device is controlled to enter the corresponding working mode. This can realize the change of the airflow field of the cooling device, taking into account the operation mode of the cooling device from the user's perspective, thereby achieving the natural wind simulation effect of the cooling device and improving user comfort and experience.

[0103] According to the refrigeration equipment provided in the embodiments of this application, by using a main air duct 720 and an auxiliary air duct 740 connected to the main air duct 720, the circulating air volume of the refrigeration equipment can be increased, thereby improving temperature uniformity. On this basis, the ambient temperature of the environment in which the refrigeration equipment is located can be obtained based on an indoor temperature sensor 510 and a controller 520, and the refrigeration equipment can be controlled to enter a corresponding working mode based on at least one of the ambient temperature or a first input from the user. This can realize the change of the air field of the refrigeration equipment outlet, taking into account the operation mode of the refrigeration equipment from the user's perspective, thereby achieving the natural wind simulation effect of the refrigeration equipment and improving user comfort and experience.

[0104] The specific execution logic of controller 520 is explained below.

[0105] 1. The refrigeration equipment enters natural wind mode immediately upon startup.

[0106] like Figure 2 As shown, in some embodiments, the controller 520 may be used to perform the following steps:

[0107] Upon receiving the user's first input, the auxiliary fan 730 is turned on; based on the ambient temperature and the first set temperature, the speed of the main fan 710 and the opening angle of the first air guide plate 7211 are adjusted.

[0108] In this embodiment, the first input is used to determine whether to enter the natural wind mode, which can be understood as the user setting the natural wind mode when turning on the device.

[0109] The first input can be in at least one of the following ways:

[0110] Firstly, the first input can be a touch operation, including but not limited to click, swipe, and press operations.

[0111] In this embodiment, receiving the user's first input can be receiving the user's touch operation on the display area of ​​the terminal screen.

[0112] In actual implementation, the first input can be achieved through the user interface set on the refrigeration equipment, or through the display screen of a mobile terminal that communicates with the refrigeration equipment, such as a mobile phone.

[0113] For example, after the cooling equipment is turned on, the terminal display shows the control interface, and the user can touch the target control used to turn on the natural wind mode to achieve the first input.

[0114] Secondly, the first input can be a physical button input.

[0115] In this embodiment, the user's first input can be received through a remote control device that is communicatively connected to the refrigeration equipment or through physical buttons installed on the refrigeration equipment. This can be receiving the user's operation of pressing the corresponding physical button; the first input can also be a combination operation of pressing multiple physical buttons simultaneously.

[0116] Thirdly, the first input can be voice input.

[0117] In this embodiment, when the cooling device receives a voice message such as "Turn on natural wind mode", it is triggered to enter natural wind mode.

[0118] Of course, in other embodiments, the first input may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs, and this application embodiment does not limit it.

[0119] The first set temperature can be the user-defined set temperature of 720 for the main air duct.

[0120] Under different ambient temperatures and different first set temperatures, the speed of the main fan 710 and the opening angle of the first air guide plate 7211 can be adjusted based on the difference between the ambient temperature and the first set temperature to control and adjust the wind speed and wind direction of the main air duct 720, so as to simulate natural wind output.

[0121] According to the refrigeration device provided in the embodiments of this application, when a user’s first input is received, the auxiliary fan 730 is turned on, and the speed of the main fan 710 and the opening angle of the first air guide plate 7211 are adjusted based on the ambient temperature and the first set temperature. This can adjust the working state of the main air duct to enhance the effect of the auxiliary air duct and the main air duct simulating natural wind together.

[0122] In some embodiments, the controller 520 may be used to perform the following steps:

[0123] The controller 520 is used to control the main fan 710 to rotate at maximum speed and / or adjust the opening of the first air guide plate 7211 to the maximum angle when the absolute value of the difference between the ambient temperature and the first set temperature is greater than a first threshold.

[0124] If the absolute value of the difference between the ambient temperature and the first set temperature is not greater than the first threshold, the speed of the main fan 710 is automatically adjusted based on the first set temperature, and / or the opening angle of the first air guide plate 7211 is adjusted to cycle between the maximum angle and the minimum angle.

[0125] In this embodiment, the degree of difference can be the difference or ratio between the ambient temperature and the first set temperature, etc.

[0126] The first threshold can be the threshold temperature value at which the main air duct 720 enters the open state.

[0127] The first set temperature is the set temperature of 720 for the main air duct.

[0128] The first threshold can be used to measure the difference between the ambient temperature and the set temperature of the main air duct 720.

[0129] In practical applications, the first threshold can be obtained based on prior experiments or set by the user.

[0130] For example, the first threshold can be 2℃, 3℃, 3.5℃ or other values, which are not limited in this application.

[0131] Control the main fan 710 to rotate at its maximum speed, that is, the air outlet speed of the main air duct 720 is at its maximum.

[0132] The first air guide plate 7211 is opened to its maximum angle, that is, the main air outlet 721 is in the state of maximum open area.

[0133] The opening of the first air guide plate 7211 to its maximum angle can be understood as the first air guide plate 7211 being in a state of tilting from the inside out and downwards, i.e., the lowest position.

[0134] The automatic adjustment of the main fan speed based on the first set temperature can be understood as the controller 520 automatically sensing the indoor temperature according to the first set temperature and automatically adjusting the wind speed of the main air duct 720.

[0135] The opening angle of the first air guide plate 7211 changes cyclically between the maximum and minimum angles, which can be understood as the first air guide plate 7211 being in an up-and-down sweeping state.

[0136] The first air guide plate 7211 is in an up-and-down sweeping state, which can be understood as the first air guide plate 7211 rotating from the lowest position to the outside and then to the closed state closest to the main air outlet 721, i.e., the highest position state.

[0137] The range from the lowest position to the highest position can be the range of the movement trajectory of the first air guide plate 7211 when the main air duct 720 is in the open state, that is, the opening range of the main air outlet 721. This range is set before the refrigeration equipment leaves the factory.

[0138] Understandably, when the absolute value of the difference between the ambient temperature and the set temperature of the main air duct 720 is greater than the threshold temperature, the speed of the main fan 710 can be adjusted to the maximum to increase the airflow velocity of the main air duct 720; or the first air guide plate 7211 can be adjusted to the lowest position to increase the airflow volume of the main air duct 720; or the speed of the main fan 710 can be adjusted to the maximum while the first air guide plate 7211 is adjusted to the lowest position to increase the airflow velocity and airflow of the main air duct 720, thereby achieving rapid cooling or heating in the cooling or heating mode of the refrigeration equipment.

[0139] If the absolute value of the difference between the ambient temperature and the set temperature of the main air duct 720 is not greater than the threshold temperature, the speed of the main fan 710 is automatically adjusted based on the first set temperature to automatically adjust the airflow speed of the main air duct 720; or the first air guide plate 7211 can be adjusted to a vertical sweeping state to gently blow air; or the speed of the main fan 710 can be automatically adjusted based on the first set temperature while the first air guide plate 7211 is adjusted to a vertical sweeping state to achieve a gentle cooling or heating when the set temperature is close to the ambient temperature in the cooling or heating mode of the refrigeration equipment, thereby improving user comfort.

[0140] The following example illustrates this implementation: a user uses an air conditioner in a bedroom setting.

[0141] like Figure 2 As shown, when the user turns on the air conditioner and sets it to natural wind mode, with the first threshold set to 3℃, the air conditioner determines the absolute value ΔT of the difference between the indoor temperature Th and the set temperature Ts of the main air duct 720. When ΔT is greater than 3℃, the airflow speed of the main air duct 720 is adjusted to the maximum speed, and the first air guide plate 7211 is in the lowest position, so that the main air outlet 721 is at its maximum and the airflow is fastest. When ΔT is not greater than 3℃, the airflow speed of the main air duct 720 is adjusted to automatic speed, that is, the speed of the main fan 710 is automatically adjusted based on the first set temperature, and the first air guide plate 7211 of the main air outlet 721 is in an up-and-down sweeping state, so that the airflow from the main air duct 720 is gentle and comfortable.

[0142] Understandably, when the absolute value of the difference between the ambient temperature and the first set temperature is greater than the first threshold, it is considered necessary to quickly reduce the difference between the ambient temperature and the first set temperature. This can be achieved by adjusting the speed of the main fan 710 to the maximum or adjusting the first air guide plate 7211 to the maximum angle, at least one of these two methods, to quickly lower or raise the ambient temperature to meet the user's needs.

[0143] If the absolute value of the difference between the ambient temperature and the first set temperature is not greater than the first threshold, it is considered that the difference between the ambient temperature and the first set temperature is small. The speed of the main fan 710 can be automatically adjusted based on the first set temperature to automatically adjust the airflow speed of the main air duct 720, or the first air guide plate 7211 can be adjusted to an up-and-down sweeping state. At least one of these two methods is used to gently lower or raise the ambient temperature, prioritizing user comfort.

[0144] According to the refrigeration device provided in the embodiments of this application, the main fan 710 speed and the opening angle of the first air guide plate 7211 are adjusted based on the ambient temperature and the first set temperature. This can improve the user's comfort experience while satisfying the need to lower or raise the ambient temperature.

[0145] In some embodiments, the controller 520 may also be used to perform the following steps:

[0146] After the auxiliary fan 730 is turned on, upon receiving a second input from the user, the auxiliary fan 730 is turned off in response to the second input, and the speed of the main fan 710 is automatically adjusted based on the first set temperature.

[0147] In this embodiment, the second input is used to determine if the user manually exits the natural wind mode.

[0148] The second input can be the same as the first input, such as touch input, physical button input, voice input, character input, or any other feasible input method, which will not be elaborated here.

[0149] Understandably, the user's second input could be that after the auxiliary fan 730 is turned on, the user manually exits the natural wind mode, in which case the auxiliary fan 730 will turn off, and the speed of the main fan 710 will be automatically adjusted based on the first set temperature, so as to automatically adjust the airflow speed of the main air duct 720.

[0150] According to the refrigeration device provided in the embodiments of this application, by controlling the auxiliary fan 730 to turn off when the user manually exits the natural wind mode, and automatically adjusting the speed of the main fan 710 based on the first set temperature, the user can be given a comfortable transition when the refrigeration device switches from natural wind mode to regular air outlet mode, thus improving the user experience.

[0151] In some embodiments, the controller can also be used to perform the following steps:

[0152] After automatically adjusting the speed of the main fan 710 based on the first set temperature, the opening angle of the first air guide plate 7211 is adjusted based on the cooling / heating mode.

[0153] In this embodiment, for example, such as Figure 2 As shown, when the air conditioner is in cooling mode, if the user manually exits the natural wind mode, the first air guide plate 7211 will be opened to the maximum angle; when the air conditioner is in heating mode, if the user manually exits the natural wind mode, the first air guide plate 7211 will be opened to the minimum angle.

[0154] It is understandable that when the refrigeration equipment is in cooling mode, opening the first air guide plate 7211 to its maximum angle can utilize the principle of hot air rising and cold air sinking to quickly and evenly distribute the indoor ambient temperature; the same applies when the refrigeration equipment is in heating mode.

[0155] According to the refrigeration equipment provided in the embodiments of this application, after automatically adjusting the speed of the main fan 710 based on the first set temperature, the opening angle of the first air guide plate 7211 is adjusted based on the refrigeration or heating mode. The principle of hot air rising and cold air sinking can be used to quickly and evenly distribute the indoor ambient temperature and improve the corresponding refrigeration or heating efficiency of the refrigeration or heating mode.

[0156] 2. Power on and enter normal airflow mode

[0157] In some embodiments, the controller 520 may also be used to perform the following steps:

[0158] Upon receiving a third input from the user, and with the auxiliary fan 730 turned on, the speed of the main fan 710 is reduced, and / or the opening angle of the first air guide plate 7211 is adjusted to cycle between the maximum and minimum angles.

[0159] In this embodiment, the third input is used to determine whether the user will enter the natural wind mode upon powering on.

[0160] The third input can be the same as the first input, such as touch input, physical button input, voice input, character input, or any other feasible input method, which will not be elaborated here.

[0161] For example, when a user selects the normal airflow mode via a remote control, the cooling equipment responds to the third input and determines that it will not enter the natural wind mode.

[0162] When the auxiliary fan 730 is turned on, the cooling equipment switches to natural wind mode.

[0163] When the third input is used to determine that the device will not enter the natural wind mode, and the auxiliary fan 730 is turned on, it can be understood that the cooling device responds to the third input and does not enter the natural wind mode. After running in the normal air outlet mode for a period of time, the cooling device receives the target instruction and enters the natural wind mode.

[0164] For example, the target instruction may include the automatic detection results of the refrigeration equipment or user input information.

[0165] Reducing the speed of the main fan 710 can reduce it to one speed lower than that of the auxiliary fan 730 before it is turned on, thereby reducing the airflow speed of the main air duct 720.

[0166] The opening angle of the first air guide plate 7211 is adjusted to cycle between the maximum and minimum angles. This can be understood as adjusting the first air guide plate 7211 to be in an up-and-down sweeping state to gently blow air.

[0167] Understandably, when the user turns on the device and enters the normal airflow mode, and the cooling equipment subsequently enters the natural wind mode after running in the normal airflow mode for a period of time, the speed of the main fan 710 can be reduced, or the first air guide plate 7211 can be adjusted to be in an up-and-down sweeping state, or the speed of the main fan 710 can be reduced and the first air guide plate 7211 can be adjusted to be in an up-and-down sweeping state, so as to reduce the wind speed of the main air duct 720 and / or adjust the wind direction of the main air duct 720 to deliver gentle airflow.

[0168] According to the refrigeration equipment provided in the embodiments of this application, when the user turns on the device and enters the normal air outlet mode, and the refrigeration equipment subsequently enters the natural wind mode after running in the normal air outlet mode for a period of time, the main air outlet can be gently vented by reducing the speed of the main fan 710 or adjusting the first air guide plate 7211 to be in an up-and-down sweeping state, thereby improving the user's comfort.

[0169] like Figure 3As shown, in some embodiments, the controller 520 can also be used to perform the following steps:

[0170] After receiving the user's third input, if the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the auxiliary fan 730 is turned on.

[0171] In this embodiment, the second set temperature can be the set temperature of the auxiliary air duct 740 set by the user.

[0172] In actual operation, the second set temperature may be the same as or different from the first set temperature.

[0173] For example, the first set temperature and the second set temperature are both 25℃ or 26℃; or the first set temperature is 26℃ and the second set temperature is 25.5℃.

[0174] Of course, in other embodiments, the first set temperature and the second set temperature can also be set to other temperature values.

[0175] The second threshold can be the threshold temperature value at which the auxiliary fan 730 enters the on state, which can be used to measure the difference between the ambient temperature and the set temperature of the auxiliary air duct 740.

[0176] In practical applications, the second threshold can be obtained based on prior experiments or set by the user.

[0177] The second threshold can be the same as or different from the first threshold.

[0178] For example, the first threshold and the second threshold are both 1℃, 2℃ or 3℃, etc.; or the first threshold is 1℃ and the second threshold is 2℃.

[0179] Of course, in other embodiments, the first threshold and the second threshold can also be set to other temperature values.

[0180] It is understandable that after the user turns on the device without entering the natural wind mode, but when the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the auxiliary fan 730 can be turned on, that is, the cooling device can be controlled to enter the natural wind mode.

[0181] According to the cooling device provided in the embodiments of this application, after the user turns on the device without entering the natural wind mode, but when the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the auxiliary fan 730 is turned on to simulate natural wind comfort when the difference between the ambient temperature and the second set temperature is small, thereby improving the user's comfort and experience.

[0182] In some embodiments, the controller 520 may also be used to perform the following steps:

[0183] After receiving the user's third input, if the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold and the duration is not less than the second time threshold, the auxiliary fan 730 is controlled to turn on.

[0184] In this embodiment, the second time threshold can be determined by experiment or set by the user.

[0185] According to the refrigeration device provided in the embodiments of this application, by setting a second time threshold, the frequent opening and closing of the auxiliary fan 730 caused by data fluctuations around the second threshold can be prevented, thereby maintaining the stability of the refrigeration device in controlling the auxiliary fan 730.

[0186] In some embodiments, the controller 520 may also be used to perform the following steps:

[0187] After receiving the user's third input, and after the cooling equipment has been turned on for a first time threshold, if the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the auxiliary fan 730 is controlled to turn on.

[0188] In this embodiment, the first threshold time can be a period of time during which the refrigeration equipment is turned on and operates in the normal air outlet mode.

[0189] For example, such as Figure 3 As shown, when the refrigeration equipment is turned on in normal air outlet mode and runs in normal air outlet mode for time t1, if the absolute value of the difference between the ambient temperature Th and the second set temperature Ts is less than 1℃, the auxiliary fan 730 can be controlled to enter the on state.

[0190] Understandably, after the cooling equipment is turned on in normal airflow mode and operates in normal airflow mode for a first time threshold, and the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the cooling equipment can be controlled to enter natural airflow mode.

[0191] The first threshold time can be determined by experimentation or set by the user.

[0192] According to the refrigeration device provided in the embodiments of this application, by setting a first time threshold, the device can be controlled to enter the natural wind mode when the user turns on the device without entering the natural wind mode. However, after the refrigeration device has been running for a period of time, if the absolute value of the difference between the ambient temperature and the second set temperature is less than the second threshold, the refrigeration device can be controlled to enter the natural wind mode. This can maintain the stability of the user's normal operation mode when turning on the device, reduce the frequency of switching of the refrigeration device's working mode, and improve the user experience.

[0193] Continue to refer to Figure 3 In some embodiments, the controller 520 may also be used to perform the following steps:

[0194] After receiving the user's third input, receive the user's fourth input;

[0195] In response to the fourth input, the auxiliary fan 730 is turned on.

[0196] In this embodiment, the fourth input is used to determine whether the refrigeration equipment is switched to normal air outlet mode after being turned on.

[0197] Understandably, the fourth input could be that after the cooling equipment is turned on in normal airflow mode and runs in normal airflow mode for a period of time, the user manually switches to natural airflow mode.

[0198] The fourth input can be the same as the first input, such as touch input, physical button input, voice input, character input, or any other feasible input method, which will not be elaborated here.

[0199] The following example, using an air conditioner in a bedroom, illustrates the process of turning on the auxiliary fan 730:

[0200] like Figure 3 As shown, when the user turns on the machine, it is in the normal air outlet mode. The second threshold is set to 1℃. After the machine is turned on for t1 time, it is determined whether the auxiliary air duct 740 is turned on. When the absolute value of the difference between the indoor temperature Th and the set temperature Ts of the auxiliary air duct 740 is less than 1℃ and is maintained for more than t2 time, or when the user manually sets the natural wind mode after the machine is turned on, the auxiliary fan 730 enters the on state.

[0201] According to the refrigeration equipment provided in the embodiments of this application, by controlling whether the auxiliary fan 730 is turned on in multiple ways based on the difference between the ambient temperature and the set temperature or the user manually sets the natural wind mode when the user turns on the equipment in the normal air outlet mode, the control of the refrigeration equipment entering the natural wind mode can be diversified, thereby improving the user experience.

[0202] like Figure 3 As shown, in some embodiments, the controller 520 can also be used to perform the following steps:

[0203] After the auxiliary fan 730 is turned on, if the absolute value of the difference between the ambient temperature and the second set temperature is greater than the third threshold, the auxiliary fan 730 will be turned off.

[0204] In this embodiment, the third threshold can be the threshold temperature value at which the auxiliary fan 730 of the auxiliary air duct 740 enters the off state.

[0205] The third threshold can be used to measure the difference between the ambient temperature and the set temperature of the auxiliary air duct 740.

[0206] In practical applications, the third threshold can be obtained based on prior experiments or set by the user.

[0207] After the auxiliary fan 730 is turned on, during the operation of the cooling equipment, the indoor temperature sensor 510 can collect the real-time ambient temperature at a target time interval, and compare the collected ambient temperature with a third threshold in real time to determine whether the auxiliary fan 730 needs to be turned off.

[0208] like Figure 3 As shown, in some embodiments, the fifth processing module can also be used to perform the following steps:

[0209] After the auxiliary fan 730 is turned on, the user's fifth input is received;

[0210] In response to the fifth input, the auxiliary fan 730 is turned off.

[0211] In this embodiment, the fifth input is used to determine whether to enter the natural wind mode after the refrigeration equipment is turned on in the normal air outlet mode, and then to determine whether to exit the natural wind mode.

[0212] Understandably, the fifth input could be that the refrigeration equipment is turned on in normal airflow mode and runs in normal airflow mode for a period of time, after which the user manually switches to natural airflow mode, and then the user manually switches out of natural airflow mode.

[0213] The fifth input can be the same as the first input, such as touch input, physical button input, voice input, character input, or any other feasible input method, which will not be elaborated here.

[0214] According to the refrigeration device provided in the embodiments of this application, by controlling whether the auxiliary fan 730 enters the off state based on the difference between the ambient temperature and the set temperature, the problem of the ambient temperature rising affecting the user experience in natural wind mode can be reduced, thereby improving the user experience and comfort. Furthermore, by controlling the auxiliary fan 730 to turn off based on the difference between the ambient temperature and the set temperature or by the user manually exiting the natural wind mode, the control of the refrigeration device exiting the natural wind mode can be diversified, thereby improving the user experience.

[0215] In some embodiments, the controller 520 may also be used to perform the following steps:

[0216] While the auxiliary fan 730 is on, the controller 520 controls to reduce the speed of the main fan 710. After the auxiliary fan 730 is turned off, the controller controls to increase the speed of the main fan 710.

[0217] In this embodiment, increasing the speed of the main fan 710 can be achieved by adjusting the speed of the main fan 710 to the speed before the auxiliary fan 730 is turned on, thereby increasing the wind speed of the main air duct 720.

[0218] It is understandable that increasing the speed of the main fan 710 corresponds to decreasing the speed of the main fan 710. When the auxiliary fan 730 is on, the speed of the main fan 710 is not decreased. After the auxiliary fan 730 is turned off, the speed of the main fan 710 is not increased.

[0219] For example, such as Figure 3 As shown, when the user turns on the device, it is in normal airflow mode. The second threshold is set to 1℃ and the third threshold is set to 3℃. After a time t1 after power-on, it is determined whether the auxiliary air duct 740 should be turned on. When the absolute value of the difference between the indoor temperature Th and the set temperature Ts of the auxiliary air duct 740 is less than 1℃ and is maintained for more than t2, or when the user manually sets the natural wind mode after power-on, the auxiliary fan 730 is turned on, and the speed of the main fan 710 is adjusted to one level lower than the speed before the auxiliary fan 730 is turned on. The absolute value of the difference between the real-time indoor temperature Th and the set temperature Ts of the auxiliary air duct 740 is judged again. When the absolute value of the difference between the indoor temperature Th and the set temperature Ts of the auxiliary air duct 740 is greater than 3℃, or when the user manually exits the natural wind mode, the auxiliary fan 730 is turned off, and the speed of the main fan 710 is adjusted to one level higher than the speed when the auxiliary fan 730 is turned on, that is, adjusted to the speed before the auxiliary fan 730 is turned on.

[0220] According to the refrigeration equipment provided in the embodiments of this application, by controlling the reduction of the main fan 710 speed while the auxiliary fan 730 is on after the auxiliary fan 730 is turned off, and then controlling the increase of the main fan 710 speed, the speed of the main fan 710 can be readjusted to the state before the auxiliary fan 730 is turned on. This facilitates the adjustment of the main fan 710 speed when the auxiliary fan 730 is turned on again, enhances the control logic of the controller 520, and thus improves the stability and safety of the refrigeration equipment.

[0221] The following section explains the various modified structures of refrigeration equipment and the corresponding execution logic for each modified structure.

[0222] like Figure 10 As shown, in some embodiments, the refrigeration device may further include a sliding air guide plate 1010, and the controller 520 may also be used to perform the following steps:

[0223] With the auxiliary fan 730 turned on, control the sliding air guide plate to slide laterally along the auxiliary air outlet 741.

[0224] In this embodiment, the sliding air guide plate 1010 is an air guide plate that can slide laterally in the auxiliary air outlet 741. It is disposed in the auxiliary air outlet 741 and is used to change the airflow direction of the auxiliary air outlet 741.

[0225] The longitudinal height of the sliding air guide plate 1010 is the same as the longitudinal height of the auxiliary air outlet 741, and the lateral length of the sliding air guide plate 1010 can be half or one-third of the lateral length of the auxiliary air outlet 741, etc.

[0226] Understandably, the sliding air deflector 1010 can completely block half or one-third of the auxiliary air outlet 741.

[0227] In actual implementation, the wind field can be changed by continuously sliding the sliding guide plate 1010 along the auxiliary air outlet 741, thereby simulating natural wind through the auxiliary air duct 740.

[0228] In addition, temperature-controlled air delivery can be achieved by controlling the sliding air guide plate 1010 to stay at the far left or far right.

[0229] It is understandable that when the sliding air guide plate 1010 is located at the far left, the air outlet of the right auxiliary air duct 740 is not blocked. The air volume on the right can be understood as the sum of the air volume of the main air duct 720 and the auxiliary air duct 740. That is, when the refrigeration equipment is in refrigeration mode, the cold air volume on the right side of the refrigeration equipment is greater than the cold air volume on the left side, so the temperature on the right side is lower than that on the left side. The same applies when the sliding air guide plate 1010 is located at the far right.

[0230] According to the refrigeration equipment provided in the embodiments of this application, by setting a sliding air guide plate 1010 in the auxiliary air outlet 741, the sliding air guide plate 1010 can be continuously circulated and laterally slid along the auxiliary air outlet 741 to realize wind field changes, thereby simulating natural wind.

[0231] like Figure 8 As shown, in some embodiments, the auxiliary fan 730 may include a cross-flow fan 810.

[0232] In this embodiment, the cross-flow fan 810 is a cross-flow fan, a special type of fan that is generally tower-shaped, but can also be large cylindrical.

[0233] The cross-flow fan 810 can be installed inside the auxiliary air duct 740, serving as the auxiliary fan 730 of the auxiliary air duct 740.

[0234] like Figure 9 As shown, in some embodiments, the auxiliary fan 730 may include a plurality of centrifugal fans 910, and the controller 520 may also be used to perform the following steps:

[0235] With the auxiliary fan 730 on, the target centrifugal fan among the multiple centrifugal fans is kept on continuously, while the other centrifugal fans among the multiple centrifugal fans, excluding the target centrifugal fan, are turned on intermittently.

[0236] In this embodiment, the centrifugal fan 910 is a fan device that uses centrifugal force to draw gas in from the inlet, accelerate it through rotating blades, and then discharge it.

[0237] The centrifugal fan 910 can push gas to the output port by rotating blades based on the generation of centrifugal force.

[0238] Multiple centrifugal fans 910 can be installed in the auxiliary air duct 740 as auxiliary fans 730.

[0239] The target centrifugal fan 910 is the part of the centrifugal fan 910 that is normally turned on when the auxiliary fan 730 is turned on.

[0240] The target centrifugal fan 910 can be configured as a combination of spaced centrifugal fans 910.

[0241] For example, four centrifugal fans 910 are installed in the auxiliary air duct 740, which are numbered 1, 2, 3 and 4 from left to right. The target centrifugal fans 910 can be number 1 and 3, number 1 and 4, or number 2 and 4.

[0242] The intermittent on / off mode is to turn on for the first duration and then turn off for the second duration.

[0243] The first and second durations can be user-defined, such as set to 3s, 5s, or other times.

[0244] In intermittent operation mode, the fan turns on for a first duration, then turns off, then turns on again for a second duration and continues for the first duration, and so on.

[0245] For example, such as Figure 4 As shown, the target centrifugal fan 910 remains constantly on. Other centrifugal fans 910, except the target centrifugal fan 910, are turned off after a duration of T1, and then turned on again after a duration of T2 and continue for a duration of T1, and this cycle repeats.

[0246] It is understandable that when the auxiliary fan 730 includes multiple centrifugal fans 910, and when the auxiliary fan 730 is turned on, some of the centrifugal fans 910 are kept on at intervals, while the remaining centrifugal fans 910 are switched on and off at timed intervals.

[0247] Continuing with the example of four centrifugal fans 910 installed in the auxiliary air duct 740, numbered 1, 2, 3, and 4 from left to right, the target centrifugal fans 910 are set as centrifugal fans 1 and 3. Then, the other centrifugal fans 910 are centrifugal fans 2 and 4. When the auxiliary fan 730 is in the on state, centrifugal fans 1 and 3 are always on. Centrifugal fans 2 and 4 are turned on after 5 seconds and turned off after 10 seconds, and this cycle continues.

[0248] According to the refrigeration equipment provided in the embodiments of this application, by setting multiple centrifugal fans 910 in the auxiliary air duct 740 and setting some centrifugal fans 910 to be constantly on and some centrifugal fans 910 to be intermittently on, the function of the sliding air guide plate 1010 to continuously slide laterally along the auxiliary air outlet 741 can be replaced to realize the simulation of natural wind.

[0249] This application also provides a non-transitory computer-readable storage medium storing a computer program.
