Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to an air conditioning range hood and its control method. Background Technology

[0002] Air-conditioned range hoods can generate cool air while extracting cooking fumes, thus optimizing the cooking environment. Currently, air-conditioned range hoods can use a shared exhaust duct for heat dissipation, meaning the cooling system and the range hood share the same duct for cooling.

[0003] The condenser of the refrigeration system is located inside the flue. The heat dissipated by the condenser is discharged into the common flue along with the cooking fumes. When a larger cooling capacity is needed, the heat dissipation of the condenser needs to be increased, i.e., the heat dissipation surface of the condenser needs to be raised. This leads to excessive air resistance in the flue, affecting the smoke extraction efficiency. Conversely, to reduce air resistance, the heat dissipation of the condenser cannot be guaranteed, resulting in poor cooling performance of the refrigeration system. Therefore, it is difficult to simultaneously meet the cooling capacity and the air volume requirements of the flue when the refrigeration system and the range hood share the same channel for heat dissipation into the common flue. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioning range hood and its control method to alleviate the technical problem of high resistance in the flue of existing air conditioning range hoods.

[0005] In a first aspect, the present invention provides an air conditioning range hood, comprising:

[0006] Refrigeration system, which includes a condenser;

[0007] The first heat exchange channel includes a smoke inlet connected to a smoke hood and a smoke outlet connected to a fan assembly. The condenser of the refrigeration system is located inside the first heat exchange channel.

[0008] The second heat exchange channel is located outside the first heat exchange channel. The second heat exchange channel includes an air inlet that communicates with the outside and an air outlet that is connected to the fan assembly.

[0009] The electric refrigeration module has a heat absorption section located in the first heat exchange channel and a heat dissipation section located in the second heat exchange channel. Along the airflow direction of the first heat exchange channel, the heat absorption section is located in front of the condenser so that the flue gas passes through the heat absorption section first and then through the condenser.

[0010] The first temperature detection module is set in the first heat exchange channel and is used to detect the temperature T1 in the first heat exchange channel.

[0011] The controller is connected to both the electric cooling module and the first temperature detection module. The controller determines whether to activate the electric cooling module based on the temperature T1 in the first heat exchange channel.

[0012] Furthermore, a cooling fan is installed in the second heat exchange channel to generate airflow from the air inlet to the air outlet.

[0013] Furthermore, the air conditioner range hood includes a second temperature detection module, which is used to detect the indoor temperature T2;

[0014] The second temperature detection module and the cooling fan are both connected to the controller. The controller adjusts the cooling level of the cooling module, the air outlet level of the cooling module, the electric cooling level of the electric cooling module, and the air outlet level of the cooling fan according to the indoor temperature T2.

[0015] Furthermore, along the airflow direction of the second heat exchange channel, the cooling fan is positioned between the air outlet and the electric cooling module.

[0016] Furthermore, a filter is installed at the air inlet.

[0017] Furthermore, the heat dissipation section includes fins, which are parallel to the airflow direction of the second heat exchange channel.

[0018] Furthermore, the number of second heat exchange channels is greater than or equal to two.

[0019] Secondly, the present invention provides an air conditioner range hood control method, which is based on the aforementioned air conditioner range hood and is executed by a controller, including the following steps:

[0020] Step S1. Obtain the temperature T1 in the first heat exchange channel collected by the first temperature detection module;

[0021] Step S2. Compare T1 with n, where n is the first preset temperature;

[0022] When T1≥n, the electric cooling module is activated.

[0023] When T1 < n, the control electric cooling module is turned off.

[0024] Furthermore, the cooling system has an adjustable cooling level, and can be adjusted to at least the first cooling level and the second cooling level; the cooling system also has an adjustable air outlet level, and can be adjusted to at least the first air outlet level and the second air outlet level.

[0025] In step S2, when T1 < n, the controller controls the electric cooling module to shut down and controls the cooling system to cool at the first cooling level; the controller controls the cooling system to discharge air at the first air outlet level.

[0026] The cooling power of the first cooling setting is less than that of the second cooling setting; the air outlet power of the first air outlet setting is less than that of the second air outlet setting.

[0027] Furthermore, a cooling fan is installed in the second heat exchange channel to generate airflow from the air inlet to the air outlet; the air conditioning range hood includes a second temperature detection module, which is used to detect the indoor temperature T2; both the second temperature detection module and the cooling fan are connected to the controller.

[0028] The cooling system has an adjustable cooling level; the cooling system has an adjustable air outlet level; the cooling fan has an adjustable air outlet level; the electric cooling module has an adjustable cooling level.

[0029] The control method includes the following steps performed after the start-up of the electric cooling module:

[0030] Step S3. Obtain the indoor temperature T2 collected by the second temperature detection module;

[0031] Step S4. Compare T2 with m, where m is the second preset temperature;

[0032] When T2 < m, control the electric cooling module to dissipate heat at the third electric cooling level; control the cooling fan to dissipate heat at the third cooling level; control the cooling system to cool at the third cooling level; control the cooling system to discharge air at the third air outlet level.

[0033] When T2≥m, control the electric cooling module to dissipate heat at the fourth electric cooling level; control the cooling fan to dissipate heat at the fourth cooling level; control the refrigeration system to cool at the fourth cooling level; control the refrigeration system to exhaust air at the fourth exhaust level.

[0034] Among them, the power of the fourth electric cooling setting is greater than that of the third electric cooling setting; the power of the fourth heat dissipation setting is greater than that of the third heat dissipation setting; the power of the fourth cooling setting is greater than that of the third cooling setting; and the power of the fourth air outlet setting is greater than that of the third air outlet setting.

[0035] The present invention has at least the following advantages or beneficial effects:

[0036] The air conditioning range hood provided by this invention includes: a refrigeration system, a first heat exchange channel, a second heat exchange channel, an electric refrigeration module, a first temperature detection module, and a controller. The refrigeration system includes a condenser. The first heat exchange channel includes a smoke inlet connected to a smoke collection hood and a smoke outlet connected to a fan assembly. The condenser of the refrigeration system is located inside the first heat exchange channel. The second heat exchange channel is located outside the first heat exchange channel and includes an air inlet communicating with the outside and an air outlet connected to the fan assembly. The heat absorption part of the electric refrigeration module is located inside the first heat exchange channel, and the heat dissipation part of the electric refrigeration module is located inside the second heat exchange channel. Along the airflow direction of the first heat exchange channel, the heat absorption part is located in front of the condenser so that the flue gas passes through the heat absorption part first and then through the condenser. The first temperature detection module is located inside the first heat exchange channel and is used to detect the temperature T1 inside the first heat exchange channel. The controller is connected to the electric refrigeration module and the first temperature detection module respectively, and the controller determines whether to turn on the electric refrigeration module based on the temperature T1 inside the first heat exchange channel.

[0037] When the air-conditioning range hood provided by this invention is in use, the fan assembly starts, and the oil fumes entering the range hood first enter the inlet and then flow towards the outlet. Simultaneously, the first temperature detection module can detect the temperature T1 within the first heat exchange channel. When T1 is high, it indicates that the airflow through the first heat exchange channel has a poor heat exchange effect on the condenser, resulting in a heavy load on the condenser. At this time, the controller activates the electric cooling module. After the electric cooling module is activated, its heat-absorbing part lowers the surrounding temperature. The flue gas temperature decreases after passing through the heat-absorbing part. Based on the principle of energy conservation, by using the electric cooling module to initially cool the flue gas, the heat dissipation load on the condenser is reduced. This reduces the heat dissipation area of ​​the condenser in the first heat exchange channel, thereby reducing the impact of the condenser on the air duct resistance. Furthermore, the split-channel design directly transfers the heat generated by the electric cooling to the fan assembly, ensuring both the smoke extraction effect and improving the cooling effect of the air-conditioning range hood. By coordinating the smoke extraction and cooling capacity, the range hood can meet users' cooling needs while ensuring airflow. This optimizes both smoke extraction and cooling efficiency, providing users with a better cooking environment. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0053] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0054] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0055] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] like Figure 1 - Figure 2 As shown, the air conditioning range hood provided by the present invention includes: a refrigeration system 34, a first heat exchange channel 21, a second heat exchange channel 22, an electric refrigeration module, a first temperature detection module, and a controller.

[0057] The first heat exchange channel 21 connects the fume hood 10 and the fan assembly, and the three are arranged vertically in sequence. The oil fumes drawn in by the fume hood 10 enter the fan assembly after passing through the first heat exchange channel 21, and are then discharged into the common flue.

[0058] like Figure 4 - Figure 5 As shown, the refrigeration system 34 can be installed on the front surface of the first heat exchange channel 21. The refrigeration system 34 includes a housing, a cross-flow fan 341, an air inlet grille 342, an oil filter 343, a compressor 35, an expansion valve 351, a condenser 211, and an evaporator 344.

[0059] Among them, such as Figure 5 As shown, the compressor 35, evaporator 344, expansion valve 351, and condenser 211 are connected end to end, and the working medium circulates within them. The working medium circulates and cools through the refrigerant working pipe 352. The compressor 35 compresses the refrigerant into a high-pressure, high-temperature gas. The fan assembly carries away the high temperature in the condenser 211 and discharges it to the common flue through forced convection. The condenser 211 is converted into a low-temperature, high-pressure liquid. The expansion valve 351 expands the high-pressure liquid, reducing its pressure and converting the refrigerant into a low-temperature, low-pressure liquid. The cross-flow fan 341 draws in indoor air for forced convection, carrying away the cold air in the evaporator 344 and introducing the low-temperature airflow into the cooking environment, thereby providing users with low-temperature air and achieving temperature regulation of the cooking environment.

[0060] like Figure 4 As shown, the air inlet grille 342 and the oil filter 343 are installed on the bottom surface of the casing. Indoor air enters the casing by passing through the air inlet grille 342 and the oil filter 343 in sequence. The air inlet grille 342 is used to rectify the airflow, adjust the airflow angle entering the cross-flow fan 341, and optimize the inlet airflow organization. The oil filter 343 is used to purify the oil in the air and prevent oil from entering the refrigeration system 34 and affecting the refrigeration efficiency. The cross-flow fan 341 is installed inside the casing, and the outlet 345 is set on the front of the casing. The evaporator 344 is located between the cross-flow fan 341 and the outlet 345. The cross-flow fan 341 blows the airflow out from the outlet 345. The airflow absorbs the air temperature through the evaporator 344, turning the airflow into low-temperature cold air. The airflow is then blown into the room through the outlet 345 with the outlet angle adjusted, cooling the cooking environment and completing the air conditioning of the kitchen environment.

[0061] like Figure 1 - Figure 2 As shown, the condenser 211 of the refrigeration system 34 is located inside the first heat exchange channel 21. A second heat exchange channel 22 is located outside the first heat exchange channel 21. The second heat exchange channel 22 includes an air inlet communicating with the outside environment and an air outlet connected to the fan assembly. The number of second heat exchange channels 22 can be one or two. In this embodiment, the two second heat exchange channels 22 are respectively located on the left and right sides of the first heat exchange channel 21.

[0062] The heat absorption part of the electric cooling module is located in the first heat exchange channel 21, and the heat dissipation part of the electric cooling module is located in the second heat exchange channel 22. Along the airflow direction of the first heat exchange channel 21, the heat absorption part is located in front of the condenser 211, so that the flue gas passes through the heat absorption part first and then passes through the condenser 211.

[0063] like Figure 1 As shown, the heat absorption part of the electro-cooling module may include a semiconductor cooling surface 223, and the heat dissipation part may include semiconductor heat dissipation fins 224. The semiconductor cooling surface 223 is attached to the surface of the first heat exchange channel 21, and the semiconductor heat dissipation fins 224 are parallel to the extending direction of the second heat exchange channel 22, that is, arranged parallel to the vertical direction according to the airflow direction, minimizing the obstruction to the upward airflow and facilitating the airflow to pass through the fins. The number of electro-cooling modules in each second heat exchange channel 22 is at least one; in this embodiment, two are provided to further reduce the flue gas temperature.

[0064] The first temperature detection module is installed inside the first heat exchange channel 21 to detect the temperature T1 within the first heat exchange channel 21. The controller is connected to both the electric cooling module and the first temperature detection module. The controller determines whether to activate the electric cooling module based on the temperature T1 within the first heat exchange channel 21. The first temperature detection module is specifically located near the flue gas inlet to accurately detect the airflow temperature and reduce the influence of the condenser 211.

[0065] like Figure 6 As shown, when the air conditioner range hood provided by this invention is in use, the fan assembly starts, and the oil fumes entering the range hood first enter the inlet and then flow towards the outlet. Simultaneously, the first temperature detection module can detect the temperature T1 within the first heat exchange channel 21. When T1 is relatively high, it indicates that the airflow through the first heat exchange channel 21 has a poor heat exchange effect on the condenser 211, and the condenser 211 is under heavy load. At this time, the controller activates the electric cooling module. After the electric cooling module is activated, its heat-absorbing part will lower the temperature around it. After the flue gas passes through the heat-absorbing part, its temperature drops. Based on the principle of energy conservation, by using the electric cooling module to initially cool the flue gas, the heat dissipation load on the condenser 211 is reduced. Therefore, during production, the heat dissipation area of ​​the condenser located in the first heat exchange channel 21 can be set smaller, thereby reducing the impact of the condenser 211 on the air duct resistance. At the same time, through the diversion channel design, the heat generated by the electric cooling is directly transferred to the fan assembly, ensuring both the smoke extraction effect and improving the cooling effect of the air conditioner range hood. By coordinating the smoke extraction and cooling capacity, the range hood can meet users' cooling needs while ensuring airflow. This optimizes both smoke extraction and cooling efficiency, providing users with a better cooking environment.

[0066] like Figure 1 and Figure 2 As shown, a cooling fan 222 is installed in the second heat exchange channel 22 to generate airflow from the air inlet to the air outlet. Specifically, the cooling fan 222 can be located at the air inlet of the second heat exchange channel 22, that is, below the electric cooling module. The use of the cooling fan 222 can reduce the pressure distribution of the fan assembly on the second heat exchange channel 22, thereby concentrating the negative pressure in the first heat exchange channel 21, which is more conducive to improving the smoke extraction efficiency.

[0067] like Figure 7 As shown, in another possible implementation, the cooling fan 222 is positioned between the air outlet and the electric cooling module along the airflow direction of the second heat exchange channel 22. Placing the cooling fan 222 inside the second heat exchange channel 22 conceals it, facilitating equipment installation and improving aesthetics. Simultaneously, keeping the cooling fan 222 away from the user reduces noise. Furthermore, a rectifier mesh 225 can be installed below the cooling fan 222 to optimize airflow and reduce flow resistance within the second heat exchange channel 22.

[0068] Installing filter 221 at the air inlet can reduce oil contamination of the electric cooling module. Filter 221 is removable for replacement or cleaning.

[0069] The air conditioning range hood includes a second temperature detection module, which is used to detect the indoor temperature T2; the second temperature detection module and the cooling fan 222 are both connected to the controller, and the controller adjusts the cooling level of the cooling module, the air outlet level of the cooling module and the air outlet level of the cooling fan 222 according to the indoor temperature T2.

[0070] The second temperature detection module can be installed on the outer wall of the air conditioner range hood to detect the indoor temperature T2, thereby achieving automatic adjustment of the cooling effect. When the outside temperature is relatively high, it is necessary to increase the cooling capacity and the air volume at the same time, so that the generated cold air can be fully injected into the room. At the same time, because the cooling capacity increases, the burden on the condenser 211 increases. Therefore, it is necessary to simultaneously increase the air outlet speed of the cooling fan 222 and the electric cooling speed of the electric cooling module, so as to reduce the temperature of the airflow passing through the condenser 211.

[0071] like Figure 1 - Figure 3 As shown, the fan assembly may include: a casing cavity 31, a smoke fan 32, and a smoke outlet connector. The upper ports of the first heat exchange channel 21 and the second heat exchange channel 22 are both connected to the casing cavity 31. The smoke fan 32 is disposed inside the casing cavity 31, and the smoke outlet connector connects the smoke fan 32 and the common flue.

[0072] The interior of the casing 31 has a space for housing refrigeration components such as the compressor 35 and water system. The outer wall of the space is curved and its cross-section includes a guide profile 36 to reduce vortices within the casing 31, optimize the airflow structure within the cavity, and reduce flow losses.

[0073] A flip-plate mechanism 13 is rotatably connected to the smoke collection hood 10. The flip-plate mechanism 13 can open and close the inlet of the smoke collection hood 10. When the smoke machine starts, the flip-plate mechanism operates, flipping the smoke collection chamber panel to a predetermined angle to draw in the smoke generated by the smoke source and transporting the smoke to the first heat exchange channel 21 of the air conditioning smoke machine. Its main function is to draw in the smoke source smoke and control or adjust the air intake of the air conditioning smoke machine.

[0074] like Figure 8 As shown, the air conditioner range hood control method provided by the present invention, based on the above-mentioned air conditioner range hood, is executed by a controller and includes the following steps:

[0075] Step S1. The controller acquires the temperature T1 in the first heat exchange channel 21 collected by the first temperature detection module.

[0076] The first temperature detection module is installed inside the first heat exchange channel 21 to detect the temperature T1 within the first heat exchange channel 21. The controller is connected to both the electric cooling module and the first temperature detection module. The controller determines whether to activate the electric cooling module based on the temperature T1 within the first heat exchange channel 21. The first temperature detection module is specifically located near the flue gas inlet to accurately detect the airflow temperature and reduce the influence of the condenser 211.

[0077] The air conditioner range hood control method also includes: step S2. Compare T1 with n, where n is the first preset temperature; when T1≥n, control the electric cooling module to start; when T1<n, control the electric cooling module to shut down.

[0078] n is a factory-preset constant. When T1≥n, it indicates that the internal temperature of the first heat exchange channel 21 is high, and the electric cooling module needs to be activated to reduce the internal temperature of the first heat exchange channel 21 in order to improve the heat dissipation efficiency of the condenser 211 and ensure the cooling efficiency of the air conditioner range hood. When T1<n, it indicates that the internal temperature of the first heat exchange channel 21 is low, and no additional heat dissipation is needed for the condenser 211. In this case, the electric cooling module and the cooling fan 222 are not activated.

[0079] Furthermore, the cooling level of the cooling system 34 is adjustable, and can be adjusted to at least the first cooling level and the second cooling level; the air outlet level of the cooling system 34 is also adjustable, and can be adjusted to at least the first air outlet level and the second air outlet level. In step S2, when T1 < n, the controller controls the electric cooling module to shut down and controls the cooling system 34 to cool at the first cooling level; the controller controls the cooling system 34 to outlet air at the first air outlet level; wherein, the cooling power of the first cooling level is less than the cooling power of the second cooling level; the air outlet power of the first air outlet level is less than the air outlet power of the second air outlet level.

[0080] When T1 < n, the cooling requirement is relatively low. The controller controls the refrigeration system 34 to cool at the first cooling level (low setting), meaning the compressor 35 operates at low power. The controller also controls the refrigeration system 34 to discharge air at the first air outlet level (low setting), meaning the cross-flow fan 341 operates at low speed to remove heat from the evaporator 344 and introduce cool air into the room, thus meeting the cooling requirement and achieving energy saving. The cooling power of the first cooling level is less than that of the second cooling level; the air outlet power of the first air outlet level is less than that of the second air outlet level.

[0081] Furthermore, in the air conditioning range hood, a cooling fan 222 is installed in the second heat exchange channel 22 to generate airflow from the air inlet to the air outlet; the air conditioning range hood includes a second temperature detection module for detecting the indoor temperature T2; both the second temperature detection module and the cooling fan 222 are connected to the controller; the cooling level of the refrigeration system 34 is adjustable; the air outlet level of the refrigeration system 34 is adjustable; the air outlet level of the cooling fan 222 is adjustable; the cooling level of the electric refrigeration module is adjustable. The control method includes the following steps performed after the start-up step of the electric refrigeration module:

[0082] Step S3. Obtain the indoor temperature T2 collected by the second temperature detection module.

[0083] The second temperature detection module can be installed on the outer wall of the air conditioner range hood to detect the indoor temperature T2, thereby achieving automatic adjustment of the cooling effect. When the outside temperature is relatively high, it is necessary to increase the cooling capacity and the air volume at the same time, so that the generated cold air can be fully injected into the room. At the same time, because the cooling capacity increases, the burden on the condenser 211 increases. Therefore, it is necessary to simultaneously increase the air outlet speed of the cooling fan 222 and the electric cooling speed of the electric cooling module, so as to reduce the temperature of the airflow passing through the condenser 211.

[0084] Step S4. Compare T2 with m, where m is the second preset temperature; when T2 < m, control the electric cooling module to dissipate heat at the third electric cooling level; control the cooling fan 222 to dissipate heat at the third cooling level; control the cooling system 34 to cool at the third cooling level; control the cooling system 34 to exhaust air at the third air outlet level; when T2 ≥ m, control the electric cooling module to dissipate heat at the fourth electric cooling level; control the cooling fan 222 to dissipate heat at the fourth cooling level; control the cooling system 34 to cool at the fourth cooling level; control the cooling system 34 to exhaust air at the fourth air outlet level; wherein, the power of the fourth electric cooling level is greater than the power of the third electric cooling level; the power of the fourth cooling level is greater than the power of the third cooling level; the power of the fourth air outlet level is greater than the power of the third air outlet level.

[0085] m is a factory-preset constant. When T2 < m, it indicates that the indoor temperature is low. The electric cooling module is controlled to dissipate heat at the third electric cooling setting, the cooling fan 222 is controlled to dissipate heat at the third cooling setting, the refrigeration system 34 is controlled to cool at the third cooling setting, and the refrigeration system 34 is controlled to discharge air at the third air outlet setting. In other words, when T2 < m, the electric cooling module is controlled to dissipate heat at the third electric cooling setting, the cooling fan 222 uses the third cooling setting to remove the heat generated by the electric cooling to prevent the indoor temperature from becoming too low, the compressor 35 of the refrigeration system 34 uses the third cooling setting, and the cross-flow fan 341 automatically uses the third air outlet setting to discharge air, removing heat from the evaporator 344 and introducing cool air into the room.

[0086] When T2 ≥ m, it indicates a high indoor temperature. The electric cooling module is controlled to operate at the fourth electric cooling setting for heat dissipation; the cooling fan 222 is controlled to operate at the fourth cooling setting for heat dissipation; the refrigeration system 34 is controlled to operate at the fourth cooling setting for cooling; and the refrigeration system 34 is controlled to operate at the fourth air outlet setting for air dissipation. In other words, when T2 ≥ m, the electric cooling module's setting is increased to the fourth electric cooling setting to increase cooling capacity. The speed of the cooling fan 222 is also increased, i.e., its setting is increased to the fourth cooling setting, ensuring proper heat dissipation from the electric cooling module. To lower the indoor temperature, the compressor 35 of the refrigeration system 34 operates at the fourth cooling setting, and the cross-flow fan 341 operates at the fourth air outlet setting, introducing a large amount of cool air into the room.

[0087] Among them, the power of the fourth electric cooling setting is greater than that of the third electric cooling setting; the power of the fourth heat dissipation setting is greater than that of the third heat dissipation setting; the power of the fourth cooling setting is greater than that of the third cooling setting; and the power of the fourth air outlet setting is greater than that of the third air outlet setting.
