[0043] The kitchen is the main place for people to cook, and the quality of the kitchen air directly affects people's cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, air-conditioned range hoods came into being. They cool the kitchen air in summer and provide hot air to the kitchen in winter to improve cooking comfort.
[0044] In existing air-conditioning range hoods, the air outlet is divided into two parts, namely the exhaust duct of the range hood and the heat dissipation duct of the air conditioner. The two ducts converge into one duct and connect to the external exhaust duct to discharge the oil smoke and the hot air generated by the air conditioner into the external exhaust duct. If the air pressure of the range hood module is too high, the oil smoke in the exhaust duct will flow back into the heat dissipation duct, causing the oil smoke to enter the range hood and the air conditioner and pollute both, thereby polluting the indoor air.
[0045] Based on the above considerations, an air-conditioning type range hood and a control method thereof are designed. According to the ratio of the first wind pressure value of the smoke exhaust duct to the second wind pressure value of the heat dissipation duct, the exhaust air volume of the range hood module and the heat dissipation air volume of the air-conditioning module are adjusted to prevent the oil smoke in the smoke exhaust duct from flowing back into the heat dissipation duct, so that both the range hood exhaust and the air-conditioning exhaust can achieve the best effect.
[0046] Please refer to Figure 1In one embodiment, an air-conditioning type range hood includes an external exhaust duct 100, a range hood module 200, an air-conditioning module 300 and a detection module 400. The range hood module 200 has a smoke exhaust duct 201, the air-conditioning module 300 has a heat dissipation duct 301, the heat dissipation duct 301 and the smoke exhaust duct 201 converge and are connected to the external exhaust duct 100, and the detection module 400 includes a first detection mechanism 500 arranged in the smoke exhaust duct 201 and a second detection mechanism 600 arranged in the heat dissipation duct 301.
[0047] Among them, when the range hood module 200 and the air conditioning module 300 are both in operation, the first detection mechanism 500 detects the first wind pressure value in the smoke exhaust duct 201, and the second detection mechanism 600 detects the second wind pressure value in the heat dissipation duct 301, and adjusts the smoke exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 according to the ratio of the first wind pressure value to the second wind pressure value.
[0048] Understandably, reference Figure 2 As shown by the arrows, when the range hood module 200 and the air conditioning module 300 are both in operation, the oil smoke generated by the range hood module 200 is discharged to the external exhaust pipe 100 through the exhaust pipe 201, and the heat generated by the air conditioning module 300 is discharged to the external exhaust pipe 100 through the heat dissipation pipe 301. If the wind pressure of the range hood module 200 is too high, the oil smoke in the exhaust pipe 201 will flow into the heat dissipation pipe 301, causing the oil smoke to enter the room and pollute the indoor air.
[0049] The above-mentioned air-conditioning type range hood detects the wind pressure values of the smoke exhaust duct 201 and the heat dissipation duct 301 in real time, and adjusts the smoke exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air-conditioning module 300 according to the ratio of the first wind pressure value of the smoke exhaust duct 201 to the second wind pressure value of the heat dissipation duct 301, so as to prevent the oil smoke in the smoke exhaust duct 201 from flowing back into the heat dissipation duct 301, so that both the range hood exhaust and the air-conditioning exhaust can achieve the best effect and be beneficial to energy saving.
[0050] It should be noted here that, in addition to the simultaneous operation of the range hood module 200 and the air conditioning module 300 in the above embodiment, the range hood module 200 and the air conditioning module 300 may also be operated separately and independently.
[0051] In this embodiment, the first detection mechanism 500 and the second detection mechanism 600 are pressure sensors with a pressure detection function. In other embodiments, the first detection mechanism 500 and the second detection mechanism 600 may also be multifunctional sensors with both a pressure detection function and other parameter detection functions.
[0052] According to some embodiments of this application, please refer to Figure 1The air-conditioning type range hood also includes a controller, and the range hood module 200 also includes a range hood component 202 electrically connected to the controller. The smoke exhaust port of the range hood component 202 is connected to the smoke exhaust duct 201, and the controller adjusts the smoke exhaust air volume of the range hood component 202 according to the ratio of the first wind pressure value to the second wind pressure value.
[0053] Through this setting, the exhaust air volume of the range hood assembly 202 is adjusted by the ratio of the first wind pressure value to the second wind pressure value, so as to prevent the wind pressure of the range hood assembly 202 from being too high, causing the oil smoke in the exhaust duct 201 to flow into the heat dissipation duct 301, thereby preventing the oil smoke from entering the range hood and the air conditioner through the heat dissipation duct 301 and contaminating the two, thereby polluting the indoor air.
[0054] Specifically, please refer to Figure 1 The range hood assembly 202 includes a range hood volute 210, a range hood driving component 220 and a range hood impeller 230. The range hood impeller 230 is rotatably disposed in the range hood volute 210. The range hood volute 210 is connected to the smoke exhaust duct 201. The range hood driving component 220 is used to drive the range hood impeller 230 to rotate. The controller adjusts the rotation speed of the range hood driving component 220 according to the ratio of the first wind pressure value to the second wind pressure value to change the smoke exhaust air volume of the range hood module 200.
[0055] It is understandable that when the range hood module 200 is in operation, the range hood impeller 230 rotates under the drive of the range hood driver 220, so that the oil smoke in the kitchen is output from the smoke exhaust channel to the external exhaust channel. When the ratio of the first wind pressure value to the second wind pressure value is less than the preset value, the rotation speed of the range hood driver 220 can be increased, and the smoke exhaust air volume of the range hood module 200 increases; when the ratio of the first wind pressure value to the second wind pressure value is greater than the preset value, the rotation speed of the range hood driver 220 can be reduced, and the smoke exhaust air volume of the range hood module 200 decreases.
[0056] Preferably, the range hood driving member 220 is a motor, and the output shaft of the motor is connected to the range hood impeller 230 .
[0057] For further information, please refer to Figure 1 The range hood module 200 also includes a range hood 240 and a first check member 250. The range hood 240 is connected to the smoke exhaust duct 201. The first check member 250 is arranged between the smoke exhaust port of the range hood 240 and the smoke exhaust duct 201 so that the smoke can only be output from the smoke exhaust port to the smoke exhaust duct 201 in one direction.
[0058] Here, the hood volute 210 is arranged in the range hood 240. The range hood 240 has a smoke inlet and a smoke outlet, and the hood volute 210 has a hood air inlet and a hood air outlet. The hood air inlet is connected to the smoke inlet, and the hood air outlet is connected to the smoke outlet. The hood driving member 220 drives the hood impeller 230 to rotate and generate negative pressure at the smoke inlet. The oil smoke in the kitchen is sucked in from the smoke inlet and enters the smoke exhaust channel through the smoke exhaust port, and then output to the external exhaust channel through the smoke exhaust channel. By setting the first check member 250, the oil smoke flowing into the smoke exhaust channel through the smoke exhaust port will not flow back to the smoke exhaust port, so as to prevent the oil smoke from flowing back.
[0059] In this embodiment, the first check member 250 is a check valve. In other embodiments, the first check member 250 can be other control valves with a one-way check function.
[0060] According to some embodiments of this application, please refer to Figure 1 The air conditioning module 300 further includes an air conditioning mechanism 310, which is connected to the heat dissipation duct 301, and the controller adjusts the heat dissipation air volume of the air conditioning mechanism according to the ratio of the first wind pressure value to the second wind pressure value.
[0061] Through this setting, the heat dissipation air volume of the air conditioning mechanism is adjusted by the ratio of the first wind pressure value to the second wind pressure value, thereby preventing the wind pressure of the range hood assembly 202 from being too high, thereby increasing energy consumption.
[0062] Specifically, please refer to Figure 1 The air conditioning mechanism includes a condensing unit, which includes a condensing volute 311, a condensing impeller 312 and a condensing driving member. The condensing impeller 312 is rotatably arranged in the condensing volute 311. The air outlet of the condensing volute 311 is connected to the heat dissipation duct 301. The condensing driving member is used to drive the condensing impeller 312 to rotate. The controller adjusts the rotation speed of the condensing driving member according to the ratio of the first wind pressure value to the second wind pressure value to change the heat dissipation air volume.
[0063] It is understandable that the condensing volute 311 has an air inlet and an air outlet, and the heat dissipation pipe 301 is arranged at the air outlet. The airflow can enter through the air inlet, and be output to the heat dissipation pipe 301 through the air outlet, and then be output to the external exhaust channel through the heat dissipation pipe 301.
[0064] Preferably, the condensation driving member is a motor, and the output shaft of the motor is connected to the condensation impeller 312 .
[0065] For further information, please refer to Figure 1 The condensing unit further includes a second check piece 313, which is disposed between the air outlet and the heat dissipation pipe 301, so that the airflow can only be output from the air outlet to the heat dissipation pipe 301 in one direction. This arrangement can effectively prevent the oil smoke in the exhaust pipe 201 from flowing back into the heat dissipation pipe 301.
[0066] In this embodiment, the second check member 313 is a check valve. In other embodiments, the second check member 313 can be other control valves with a one-way check function.
[0067] For further information, please refer to Figure 1 The air conditioning mechanism includes a compressor, an evaporator and a condenser. The compressor, the evaporator and the condenser are interconnected to form a cooling and heating cycle. The heat dissipation port of the air conditioning mechanism is connected to the condenser.
[0068] Here, the condensation air outlet of the condenser is the heat dissipation outlet of the air conditioning mechanism, and the condensation air outlet of the condenser is connected to the heat dissipation pipeline 301. The compressor is used to output high-temperature and high-pressure gas, the condenser is used to liquefy the gas into liquid, and the evaporator is used to vaporize the liquid into gas. The compressor, condenser and evaporator are connected through a refrigerant pipeline, and the three cooperate with each other to complete the refrigeration cycle and the heating cycle.
[0069] During the refrigeration cycle, the compressor outputs high-temperature and high-pressure gas, which is condensed and liquefied into high-pressure liquid through the condenser. During this process, the condenser needs to release heat; the high-pressure liquid is evaporated and gasified into low-pressure gas and output through the evaporator. During this process, the evaporator needs to absorb heat, thereby achieving the purpose of lowering the indoor temperature. During the heating cycle, the compressor outputs high-temperature and high-pressure gas, which is condensed and liquefied into high-pressure liquid through the condenser. During this process, the condenser needs to release heat, thereby achieving the purpose of raising the indoor temperature.
[0070] Specifically, the condenser can be a spray type or a filling type, and the evaporator can be a single effect or a multi-effect type. Here, the types of the condenser and the evaporator are not specifically limited.
[0071] Please refer to Figure 1 , a control method of an air-conditioning range hood according to an embodiment includes:
[0072] S1, start the air-conditioning range hood;
[0073] S2, when the range hood module 200 and the air conditioning module 300 are both in operation, detecting a first wind pressure value in the smoke exhaust duct 201, and detecting a second wind pressure value in the heat dissipation duct 301;
[0074] S3. According to the ratio of the first wind pressure value to the second wind pressure value, the smoke exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 are adjusted.
[0075] The control method of the above-mentioned air-conditioning type range hood detects the wind pressure values of the smoke exhaust duct 201 and the heat dissipation duct 301 in real time, and adjusts the smoke exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 according to the ratio of the first wind pressure value of the smoke exhaust duct 201 to the second wind pressure value of the heat dissipation duct 301, so that both the range hood exhaust and the air conditioning exhaust can achieve the best effect and are beneficial to energy saving.
[0076] According to some embodiments of this application, please refer to Figure 1 According to the ratio of the first wind pressure value to the second wind pressure value, adjusting the exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 also includes the following steps:
[0077] The preset ratio of the first wind pressure value to the second wind pressure value is k;
[0078] When the actual ratio k1 of the first wind pressure value to the second wind pressure value is greater than k, the smoke exhaust air volume of the range hood module 200 is reduced or the heat dissipation air volume of the air conditioning module 300 is increased;
[0079] When the actual ratio k1 of the first wind pressure value to the second wind pressure value is less than k, the smoke exhaust air volume of the range hood module 200 is increased or the heat dissipation air volume of the air conditioning module 300 is reduced;
[0080] When the actual ratio k1 of the first wind pressure value to the second wind pressure value is equal to k, the smoke exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 are maintained unchanged.
[0081] In this way, the ratio of the first wind pressure value to the second wind pressure value can always be close to the preset value, and the exhaust air volume of the range hood module 200 and the heat dissipation air volume of the air conditioning module 300 are at the optimal value, thereby preventing the wind pressure of the range hood assembly 202 from being too high, causing the oil smoke in the smoke exhaust duct 201 to flow into the heat dissipation duct 301, and preventing the oil smoke from entering the range hood and air conditioner through the heat dissipation duct 301 and contaminating the two, thereby polluting the indoor air.
[0082] According to some embodiments of this application, please refer to Figure 1 The control method of the air-conditioning type range hood further comprises the following steps:
[0083] The preset value of the first wind pressure value is F;
[0084] When the actual detected value F1 of the first wind pressure value is greater than F, the smoke exhaust air volume of the range hood module 200 is reduced;
[0085] When the actual detected value F1 of the first wind pressure value is less than F, the smoke exhaust air volume of the range hood module 200 is increased;
[0086] When the actual detected value F1 of the first wind pressure value is equal to F, the smoke exhaust air volume of the range hood module 200 is maintained unchanged.
[0087] In this way, the exhaust air volume of the range hood module 200 can be adjusted in real time to prevent the wind pressure of the range hood component 202 from being too high, causing the oil smoke in the exhaust duct 201 to flow into the heat dissipation duct 301, thereby preventing the oil smoke from entering the range hood and air conditioner through the heat dissipation duct 301 and contaminating both, thereby polluting the indoor air.
[0088] According to some embodiments of this application, please refer to Figure 1 The adjustment of the smoke exhaust air volume of the range hood module 200 is achieved by changing the rotation speed of the range hood driving member 220 of the range hood module 200 .
[0089] For example, when the ratio of the first wind pressure value to the second wind pressure value is less than a preset value, the rotation speed of the range hood driving component 220 can be increased, and at this time the smoke exhaust air volume of the range hood module 200 increases; when the ratio of the first wind pressure value to the second wind pressure value is greater than the preset value, the rotation speed of the range hood driving component 220 can be reduced, and at this time the smoke exhaust air volume of the range hood module 200 decreases.
[0090] According to some embodiments of this application, please refer to Figure 1 The heat dissipation air volume of the air conditioning module 300 is adjusted by changing the rotation speed of the condensation driving component of the air conditioning module 300.
[0091] For example, when the ratio of the first wind pressure value to the second wind pressure value is greater than a preset value, the rotation speed of the condensing drive component can be increased, and the exhaust air volume of the air-conditioning module 300 increases; when the ratio of the first wind pressure value to the second wind pressure value is less than the preset value, the rotation speed of the condensing drive component can be reduced, and the exhaust air volume of the air-conditioning module 300 decreases.
[0092] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0093] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
