Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an airflow separation structure and a smoke machine. Background Technology

[0002] A cooling range hood is a kitchen appliance that integrates fume extraction and cooling functions. By combining a cooling system with fume extraction, it aims to solve the dual problems of high temperatures and cooking fumes in the kitchen. Cooling range hoods can significantly improve the cooking environment and enhance user comfort while cooking.

[0003] In existing refrigerated range hoods, when the range hood module and the air conditioning module work simultaneously, the oil fume airflow entering the back of the turbine will collide with the hot airflow, affecting the smoke extraction effect of the back of the turbine. Moreover, the hot airflow may also enter the front of the turbine, thus affecting the smoke extraction effect of the front of the turbine. Utility Model Content

[0004] In view of this, the present invention provides an airflow separation structure and a range hood device to solve the problem of interference between the oil fume airflow and the hot airflow in existing refrigerated range hoods, which affects the smoke exhaust effect.

[0005] In a first aspect, this utility model provides an airflow separation structure applied to a range hood with a cooling function. The range hood includes a housing, a blower housing inside the housing, and a fan inside the blower housing. The fan has a first fan side and a second fan side arranged opposite to each other. The airflow separation structure includes:

[0006] A first partition is reciprocally movable and disposed on the second side of the fan, which divides the fan inlet on the second side of the fan into an oil fume inlet area and a hot air inlet area.

[0007] The second partition is disposed in the hot air inlet area. One end of the second partition is connected to the first partition, and the other end is connected to the side wall of the hot air inlet area away from the entry of the oil fume. The first partition drives the second partition to unfold or retract. The second partition is used to prevent hot airflow from entering the first side of the fan.

[0008] Beneficial Effects: The airflow separation structure of this utility model includes a first separator and a second separator. The first separator divides the air inlet of the fan on the second side into an oil fume inlet area and a hot air inlet area, isolating the oil fume airflow and hot airflow on the second side of the fan. This separates the heat exhaust process from the smoke exhaust process, preventing them from interfering with each other and avoiding the oil fume airflow and hot airflow colliding. This reduces the disturbance of the hot airflow on the oil fume airflow, making the smoke exhaust process on the second side of the fan smoother and improving the smoke exhaust effect. Furthermore, the second separator can be expanded or retracted under the action of the first separator. The second separator prevents the hot airflow from entering the fan from the second side to the first side, avoiding the hot airflow and oil fume airflow colliding on the first side of the fan, reducing the disturbance of the hot airflow on the oil fume airflow, making the smoke exhaust process on the first side of the fan smoother and improving the smoke exhaust effect.

[0009] In one alternative embodiment, the side of the first separator facing the fan is fitted with the fan housing of the fan, and the side of the first separator away from the fan is slidably sealed with the inner wall of the fan cabinet.

[0010] Beneficial effects: The airflow separation structure of this utility model has a first separator that is attached to the fan housing on the side facing the fan, and a sliding seal between the side of the first separator away from the fan and the inner wall of the air handling unit. This ensures the separation effect between the oil fume entry area and the hot air entry area, making the oil fume entry area and the hot air entry area independent of each other. This further ensures that the oil fume airflow and the hot airflow will not collide on the second side of the fan, reducing the disturbance of the hot airflow to the oil fume airflow, making the smoke exhaust process on the second side of the fan smoother, and improving the smoke exhaust effect.

[0011] In one alternative embodiment, the second partition is disposed at the lower part of the hot air inlet area, and the second partition covers the hollow area between the fan housing of the fan and the inner wall of the hot air inlet area.

[0012] Beneficial effects: In the airflow separation structure of this utility model, the fan is installed inside the air handling unit. The fan housing is usually a near-cylindrical structure, and there is a fitting gap between the fan housing and the inner wall of the air handling unit. In this application, there is a hollow area between the fan housing and the inner wall of the hot air inlet area. The hot airflow from the second side of the fan can easily pass through this hollow area and enter the first side of the fan. The second separator blocks the hollow area, which can reliably prevent the hot airflow from the second side of the fan from entering the first side of the fan through the hollow area. This prevents the hot airflow from interfering with the oil fume airflow on the first side of the fan, making the smoke exhaust process on the first side of the fan smooth and ensuring the smoke exhaust effect.

[0013] In one alternative embodiment, the fan housing contacts the side wall of the hot air inlet area away from the fume inlet area, the top of the second partition is higher than or flush with the contact position between the fan housing and the side wall of the hot air inlet area away from the fume inlet area, and the bottom of the second partition slides in contact with the bottom plate of the fan cabinet.

[0014] Beneficial effects: The airflow separation structure of this utility model has a cylindrical fan casing and a planar side wall in the hot air inlet area away from the oil fume inlet area. The fan casing and the side wall in the hot air inlet area away from the oil fume inlet area have a contact position to ensure the fan is stably installed. This contact position is the top position of the hollow area. The top of the second separator is higher than or flush with this contact position so that the second separator completely covers and blocks the hollow area, ensuring that the hot airflow on the second side of the fan will not enter the first side of the fan through the hollow area, so that the smoke exhaust process on the first side of the fan is smooth and the smoke exhaust effect is guaranteed.

[0015] In one alternative embodiment, after the second partition is deployed, the second partition is parallel to the fan casing of the fan.

[0016] Beneficial effects: In the airflow separation structure of this utility model, after the second separator is unfolded, the second separator is parallel to the fan housing, making the second separator fit the fan housing better and ensuring the shielding effect of the second separator on the hollow area.

[0017] In one alternative implementation, a drive mechanism is further included, disposed within the air handling unit, for driving the first separator to reciprocate.

[0018] Beneficial effects: The airflow separation structure of this utility model, by setting a driving mechanism to drive the first separator to reciprocate, makes the reciprocating movement of the first separator controllable, thereby improving the controllability and intelligent operation of the airflow separation structure.

[0019] In one alternative embodiment, the driving mechanism includes a driving member, the driving member having a driving rod connected to the first separator.

[0020] Beneficial effects: The airflow separation structure of this utility model has a driving mechanism including a driving component, and the driving rod of the driving component is connected to the first separator. This driving mechanism is simple, easy to set up, and has low operating costs.

[0021] In one optional embodiment, the drive mechanism further includes a guide rail fixed to the inner wall of the air handling unit. The guide rail is arranged along the reciprocating movement direction of the first partition. One of the top and bottom ends of the first partition is connected to the drive rod, and the other end is movably disposed on the guide rail.

[0022] Beneficial effects: The airflow separation structure of this utility model includes a guide rail in the driving mechanism. The top or bottom end of the first separator is disposed on the guide rail so that the first separator moves back and forth along the extension direction of the guide rail, making the movement of the first separator more stable and improving the structural reliability.

[0023] Secondly, this utility model also provides a smoke hood device, including a housing, in which a fan cabinet, a smoke hood module and a refrigeration module are disposed, and a fan is disposed in the fan cabinet. The fan has a first fan side and a second fan side disposed opposite to each other, and an airflow separation structure as described above is disposed on the second fan side.

[0024] Since the smoke machine equipment of this utility model includes the airflow separation structure of this utility model and has the same beneficial effects as the airflow separation structure, it will not be described in detail here.

[0025] In one optional embodiment, the blower cabinet is provided with a flow-gathering structure, which is disposed between the inner wall of the blower cabinet and the fan housing of the blower. A flow-gathering zone is formed between the flow-gathering structure and the inner wall of the blower cabinet. The blower cabinet has a hot air inlet, the air inlet of the flow-gathering zone is connected to the hot air inlet of the blower cabinet, and the air outlet of the flow-gathering zone is connected to the hot air inlet zone.

[0026] Beneficial effects: The smoke hood equipment of this utility model has a flow-gathering structure in the air handling unit, and a flow-gathering zone is formed between the flow-gathering structure and the inner wall of the air handling unit. The air inlet of the flow-gathering zone is connected to the hot air inlet of the air handling unit, and the air outlet of the flow-gathering zone is connected to the hot air inlet area. By setting up the flow-gathering structure and flow-gathering zone, an independent channel is provided for the hot air flow blown out by the air conditioning module, reducing the disturbance between the hot air flow and the oil fume flow, and guiding the hot air flow to the second side of the fan, thus playing a guiding role in the hot air flow.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] In current range hoods, the fan power is fixed. Different cooling module settings result in different heat dissipation airflow, which in turn affects the fan airflow required for the geothermal airflow. When the cooling module setting is high, the hot airflow is large and enters the front of the turbine through the channel between the turbine housing and the air handling unit, disturbing the airflow and affecting the range hood's smoke extraction efficiency. When the cooling module setting is low, the hot airflow is small and affects the smoke extraction efficiency at the back of the turbine. This disturbance reduces the actual exhaust airflow, weakening the range hood's smoke extraction effect and preventing it from fully utilizing its airflow capacity. Furthermore, when only the range hood module is turned on, the exhaust duct to the air conditioning module is not blocked, allowing cooking fumes to enter and contaminate the air conditioning module.

[0041] The following is combined Figures 1-6 This describes embodiments of the airflow separation structure and smoke machine equipment of this utility model.

[0042] According to an embodiment of the present invention, in a first aspect, an airflow separation structure is provided, applied to a range hood with a cooling function. The range hood includes a housing 1, a blower 2 disposed inside the housing 1, and a fan 3 disposed inside the blower 2. The fan 3 has a first fan side 301 and a second fan side 302 disposed opposite to each other. The airflow separation structure includes a first separator 4 and a second separator 5. The first separator 4 is reciprocally movable and disposed on the second fan side 302, dividing the fan inlet of the second fan side 302 into an oil fume inlet area 6 and a hot air inlet area 7. The second separator 5 is disposed on the hot air inlet area 7, with one end of the second separator 5 connected to the first separator 4 and the other end connected to the side wall of the hot air inlet area 7 away from the oil fume inlet area 6. The first separator 4 drives the second separator 5 to unfold or retract, and the second separator 5 is used to prevent hot airflow from entering the first fan side 301.

[0043] In this airflow separation structure, the first separator 4 divides the fan inlet on the second side 302 of the fan into an oil fume inlet zone 6 and a hot air inlet zone 7, thus isolating the oil fume airflow and hot airflow on the second side 302 of the fan. This separates the heat exhaust process from the smoke exhaust process, ensuring that the two processes do not interfere with each other, preventing the oil fume airflow from colliding with the hot airflow, reducing the disturbance of the hot airflow on the oil fume airflow, and making the smoke exhaust process on the second side 302 of the fan smoother and improving the smoke exhaust effect. Furthermore, the second separator 5 can expand or retract under the action of the first separator 4. The second separator 5 prevents the hot airflow from entering the first side 301 of the fan from the second side 302 of the fan, preventing the hot airflow from colliding with the oil fume airflow on the first side 301 of the fan, reducing the disturbance of the hot airflow on the oil fume airflow, and making the smoke exhaust process on the first side 301 of the fan smoother and improving the smoke exhaust effect.

[0044] The airflow separation structure in this embodiment is applied to a range hood with a cooling function, namely a refrigerated range hood, which simultaneously purifies oil fumes and provides cooling. The range hood includes a housing 1, within which a range hood module and an air conditioning module are installed. The range hood module is used to exhaust oil fumes and purify kitchen air, while the air conditioning module is used to lower the kitchen temperature and improve cooking comfort. Figures 1-2 As shown, the housing 1 includes a range hood housing 101 and an air conditioner housing 102. The range hood module is housed within the range hood housing 101, while the air conditioner module is housed within the air conditioner housing 102. The range hood module and the air conditioner module are set up independently, which reduces mutual interference between modules and ensures stable operation of each module.

[0045] An air handling unit 2 is installed inside the housing 1. Specifically, an air handling unit 2 is installed inside the air conditioner housing 102. The air handling unit 2 provides space for the fan 3, which is a turbine fan. Figure 2 From a perspective perspective, the left side of the range hood is the user's standing side, and the right side is the mounting surface side (such as the wall). The fan 3 has a first fan side 301 and a second fan side 302, which are arranged back-to-back. Specifically, the first fan side 301 is the front of the turbine, and the second fan side 302 is the back of the turbine. The second fan side 302 is closer to the user's standing side than the first fan side 301. It should be noted that the fan 3 has air inlets on both the first fan side 301 and the second fan side 302.

[0046] like Figures 3-4 As shown, the air handling unit 2 is a rectangular structure with an internal space where the fan 3 is installed. The air handling unit 2 has a hot air inlet 201 and an air outlet 202. The hot air inlet 201 is connected to the exhaust duct of the air conditioning module. The hot air flow generated by the air conditioning module enters the air handling unit 2 through the hot air inlet 201. The air outlet 202 is connected to the exhaust duct of the range hood equipment. Both the hot air flow and the oil fume flow are discharged through the air outlet 202.

[0047] The airflow separation structure is installed inside the air handling unit 2. The airflow separation structure is used to separate the hot airflow and the oil fume airflow, reduce the impact and disturbance of the hot airflow on the oil fume airflow, so that the exhaust process is not affected by the heat exhaust process, ensuring the exhaust effect of the range hood equipment. In addition, it can also reduce the aerodynamic noise of the range hood equipment and improve the user experience.

[0048] In this embodiment, the airflow separation structure includes a first separator 4 and a second separator 5, both of which are disposed on the second side 302 of the fan. The first separator 4 is reciprocally movable on the second side 302 of the fan, and the reciprocating direction of the first separator 4 is as follows: Figure 3As indicated by the middle arrow x-x', the first separator 4 divides the fan inlet on the second side 302 of the fan into a fume inlet zone 6 and a hot air inlet zone 7. The fume airflow enters the fan inlet on the second side 302 of the fan from the fume inlet zone 6, while the hot airflow enters from the hot air inlet zone 7. This ensures that the fume and hot airflows do not interfere with each other, reducing the disturbance of the fume airflow by the hot airflow and ensuring the effective fume exhaust from the second side 302 of the fan. Furthermore, by reducing the collision between the hot airflow and the fume airflow, the aerodynamic noise generated by the airflow collision is reduced, resulting in a better user experience. Depending on different operating conditions, the reciprocating movement of the first separator 4 can adjust the area of ​​the fume inlet zone 6 and the hot air inlet zone 7 to regulate the amount of fan airflow occupied by the fume and hot airflows.

[0049] The second partition 5 is linked to the first partition 4. Specifically, the second partition 5 can expand or retract under the action of the first partition 4, and the direction in which the second partition 5 expands or retracts is as follows: Figure 3 As indicated by the middle arrow x-x', when the second partition 5 unfolds along with the movement of the first partition 4, the second partition 5 can prevent the hot airflow from entering the first side 301 of the fan from the second side 302 of the fan, avoiding the collision between the hot airflow and the oil fume flow on the first side 301 of the fan, reducing the disturbance of the hot airflow to the oil fume flow, making the smoke exhaust process on the first side 301 of the fan smoother, and improving the smoke exhaust effect.

[0050] Furthermore, the side of the first partition 4 facing the fan 3 is fitted with the fan housing 303 of the fan 3, and the side of the first partition 4 away from the fan 3 is slidably sealed with the inner wall of the air handling unit 2.

[0051] The fan 3 is a turbine fan, and the fan 3 has a fan housing 303, which is the turbine housing. The turbine housing contains a turbine 304, a vortex tongue 305, and other structures. Figure 2 As shown, the side of the first separator 4 facing the fan 3 is fitted with the fan housing 303, and the side of the first separator 4 away from the fan 3 is slidably sealed with the inner wall of the air handling unit 2. This ensures the separation effect between the oil fume inlet area 6 and the hot air inlet area 7, making the oil fume inlet area 6 and the hot air inlet area 7 independent of each other. This further ensures that the oil fume airflow and the hot airflow on the second side 302 of the fan will not collide, reducing the disturbance of the hot airflow to the oil fume airflow, making the smoke exhaust process on the second side 302 of the fan smoother and improving the smoke exhaust effect.

[0052] In this embodiment, the fan 3 is inclined towards the mounting surface of the smoke hood equipment to ensure sufficient suction and exhaust of oily fumes and hot air. On the second side 302 of the fan, a space with an inverted trapezoidal cross-section is formed between the fan housing 303 and the inner wall of the air handling unit 2, such as... Figure 2The first partition 4 adopts a matching inverted trapezoidal plate structure, so that the side of the first partition 4 facing the fan 3 fits against the fan housing 303, and the side of the first partition 4 away from the fan 3 slides and seals against the inner wall of the air handling unit 2, thus ensuring the separation effect between the oil fume entry area 6 and the hot air entry area 7. It should be noted that the sliding seal between the side of the first partition 4 away from the fan 3 and the inner wall of the air handling unit 2 means that during the reciprocating movement of the first partition 4, the side of the first partition 4 away from the fan 3 and the inner wall of the air handling unit 2 can slide relative to each other, but always maintain a sealed state. For example, a sealing gasket, sealing sheet, etc. can be provided between the side of the first partition 4 away from the fan 3 and the inner wall of the air handling unit 2.

[0053] Furthermore, the second partition 5 is disposed at the lower part of the hot air inlet area 7, and the second partition 5 blocks the hollow area 8 between the fan housing 303 of the fan 3 and the inner wall of the hot air inlet area 7.

[0054] like Figures 3-4 As shown, the fan 3 is installed inside the air handling unit 2. The fan 3 has a near-cylindrical structure, and there is a fitting gap between the fan housing 303 and the inner wall of the hot air inlet area 7. This fitting gap is the perforated area 8. It should be noted that perforated areas 8 are formed between the fan housing 303 and the inner wall of the hot air inlet area 7, and between the fan housing 303 and the inner wall of the fume inlet area 6. Specifically, there is a perforated area 8 between the fan housing 303 and the inner wall of the fume inlet area 6. Figure 3 8. Hollow area in the lower right corner Figure 4 The lower left corner hollow area 8), and there is also a hollow area 8 between the fan housing 303 and the inner wall of the hot air inlet area 7. Figure 4 The bottom right corner cutout area (8).

[0055] On the second side 302 of the fan, hot airflow can easily pass through the perforated area 8 between the fan housing 303 and the inner wall of the hot air inlet area 7 and enter the first side 301 of the fan, interfering with the smoke exhaust process of the first side 301. By blocking the perforated area 8 with the second separator 5, the hot airflow on the second side 302 of the fan can be reliably prevented from entering the first side 301 of the fan through the perforated area 8, thus confining the hot airflow to the hot air inlet area 7. This prevents the hot airflow on the first side 301 of the fan from interfering with the oil fume airflow, ensuring a smooth smoke exhaust process on the first side 301 and guaranteeing the smoke exhaust effect.

[0056] Furthermore, the fan housing 303 contacts the side wall of the hot air inlet area 7 away from the oil fume inlet area 6, the top of the second partition 5 is higher than or flush with the contact position between the fan housing 303 and the side wall of the hot air inlet area 7 away from the oil fume inlet area 6, and the bottom of the second partition 5 slides in contact with the bottom plate of the fan cabinet 2.

[0057] Because the fan housing 303 has a near-cylindrical structure, and the side wall of the hot air inlet area 7 away from the fume inlet area 6 is a planar structure, the fan housing 303 and the side wall of the hot air inlet area 7 away from the fume inlet area 6 have a contact position to support the fan 3 and make the fan 3 stably installed. This contact position is the top position of the hollow area 8. The top of the second partition 5 is higher than or flush with this contact position (the top position of the hollow area 8), so that the second partition 5 can completely cover and block the hollow area 8, ensuring that the hot airflow on the second side 302 of the fan will not enter the first side 301 of the fan through the hollow area 8, so that the smoke exhaust process on the first side 301 of the fan is smooth and the smoke exhaust effect is guaranteed.

[0058] In this embodiment, the top of the second partition 5 is flush with the contact position to save material of the second partition 5 and ensure the shielding effect on the hollow area 8. It can be understood that the hollow area 8 is a triangular area, while the second partition 5 unfolds into a rectangular plate structure. The area of ​​the second partition 5 after unfolding is larger than the area of ​​the hollow area 8, so that the second partition 5 can fully shield the hollow area 8.

[0059] Furthermore, after the second partition 5 is unfolded, the second partition 5 is parallel to the fan housing 303 of the fan 3.

[0060] In this embodiment, the second partition 5 is an expandable and retractable folding plate. When the second partition 5 is fully expanded, the second partition 5 is parallel to the fan housing 303 of the fan 3, so that the second partition 5 fits the fan housing 303 more closely and ensures the shielding effect of the second partition 5 on the hollow area 8, so as to limit the hot airflow to the hot air inlet area 7.

[0061] Furthermore, the airflow separation structure also includes a drive mechanism, which is located inside the air handling unit 2, for driving the first separator 4 to move back and forth.

[0062] The airflow separation structure also includes a drive mechanism, which is located inside the air handling unit 2. The drive mechanism drives the first separator 4 to move back and forth, making the reciprocating movement of the first separator 4 controllable. The movement distance of the first separator 4 can be controlled as needed (e.g., the speed of the range hood module, the speed of the air conditioning module, etc.), thereby adjusting the area of ​​the oil fume entry zone 6 and the hot air entry zone 7, improving the controllability and intelligent operation of the airflow separation structure.

[0063] In this embodiment, the driving mechanism includes a driving component 9, whose driving rod is connected to the first partition 4. The driving component 9 is a push rod motor. Specifically, a mounting plate 203 is provided on the upper part of the air handling unit 2, and the driving component 9 is disposed on the mounting plate 203. The driving component 9 is located above the first partition 4, and its driving rod can be connected to the first partition 4 to drive the first partition 4 to reciprocate.

[0064] Furthermore, the drive mechanism also includes a guide rail 10, which is fixed to the inner wall of the air handling unit 2. The guide rail 10 is arranged along the reciprocating movement direction of the first partition 4. One of the top and bottom ends of the first partition 4 is connected to the drive rod, and the other end is movably arranged on the guide rail 10.

[0065] like Figure 3 As shown, the drive mechanism also includes a guide rail 10, which is fixed to the inner wall of the air handling unit 2. In this embodiment, the guide rail 10 is fixed to the bottom wall of the air handling unit 2. The guide rail 10 is arranged along the reciprocating movement direction of the first partition 4, and plays a guiding role in the reciprocating movement of the first partition 4. Specifically, the top end of the first partition 4 is connected to the drive rod of the drive member 9, and the bottom end of the first partition 4 is movably arranged on the guide rail 10. This drive mechanism can drive the first partition 4 to reciprocate stably.

[0066] This embodiment also provides a smoke hood device, including a housing 1. The housing 1 is provided with a fan cabinet 2, a smoke hood module and a refrigeration module. The fan cabinet 2 is provided with a fan 3. The fan 3 has a fan first side 301 and a fan second side 302 arranged opposite to each other. The fan second side 302 is provided with an airflow separation structure as described above.

[0067] like Figures 1-2 As shown, this range hood is a refrigerated range hood, combining oil fume purification and cooling functions. The range hood includes a housing 1, within which are a range hood module and an air conditioning module. The range hood module is used to exhaust oil fumes and purify kitchen air, while the air conditioning module is used to lower the kitchen temperature and improve cooking comfort. The range hood also has a control system to manage its operation.

[0068] Specifically, the housing 1 includes a range hood housing 101 and an air conditioner housing 102. The range hood module is housed within the range hood housing 101, while the air conditioner module is housed within the air conditioner housing 102. The range hood module and the air conditioner module are independently configured, reducing mutual interference and ensuring stable operation of each module. In this embodiment, the air conditioner housing 102 is positioned above the range hood housing 101 to facilitate the exhaust process of the range hood module, and also features a compact structure, reduced space occupation, and improved space utilization.

[0069] A fan housing 2 is installed inside the range hood casing 101. A fan 3 is installed inside the fan housing 2. The top of the fan housing 2 is equipped with a hot air inlet 201 and a hot air outlet 202. The hot air inlet 201 is used to introduce hot air flow generated by the air conditioning module (such as... Figure 3 As indicated by the arrow at the hot air inlet 201 of the air handling unit (where b represents the hot air flow), the air outlet 202 of the air handling unit is used to exhaust oil fume and hot air (such as...). Figure 3 As indicated by the arrow at air outlet 202 of the central air handling unit, a represents the airflow of cooking fumes, and b represents the airflow of hot air.

[0070] Furthermore, a wind speed sensor 16 is installed at the hot air inlet 201 of the air handling unit. The wind speed sensor 16 is electrically connected to the control system. The wind speed sensor 16 is used to detect the wind speed of the hot air entering the hot air inlet 201 of the air handling unit (that is, the wind speed sensor 16 synchronously detects the heat dissipation air volume value of the air conditioning module in real time). The first partition 4 can adjust its position in a timely manner according to the wind speed of the hot air, so as to achieve the best smoke exhaust effect while exhausting heat.

[0071] Specifically, in order to facilitate the control of the position of the first partition 4, the guide rail is divided into ten equal parts according to the wind speed values ​​measured by the wind speed sensor 16 at each gear of the air conditioning module, and the stop position of the first partition 4 is set for each gear, with each stop position corresponding to the wind speed range of each gear.

[0072] The lower part of the range hood housing 101 is provided with an oil fume inlet 1011, and a smoke guide plate 14 and an oil cup 15 are provided at the oil fume inlet 1011. A smoke collection chamber 13 is provided inside the range hood housing 101, and the smoke collection chamber 13 is connected to the oil fume inlet 1011. When the user uses the range hood module, the oil fumes in the air enter the smoke collection chamber 13 through the oil fume inlet 1011. Most of the oil fumes then enter the fan 3 from the first side 301 and are discharged, while a small portion of the oil fumes enter the second side 302 from the first side 301 and are then discharged from the fan 3. The top of the fan 3 is provided with a fan outlet 306, which is connected to the air handling unit outlet 202. The air handling unit outlet 202 is also connected to the exhaust duct 20 of the range hood, so that the oil fume airflow and hot airflow are finally discharged from the range hood through the exhaust duct 20.

[0073] The air conditioner housing 102 houses a compressor 17, a water collection box 18, a condenser 19, and an evaporator 21. The condenser 19 includes a condenser impeller 1901 and a condenser motor 1902, and the evaporator 21 includes an evaporator impeller 2101 and an evaporator motor 2102. The air conditioner housing 102 has a cold air outlet 22 for discharging the cold air generated by the evaporator 21. The working principle diagram of the air conditioning module is shown below. Figure 5 As shown, the compressor 17, condenser 19 and evaporator 21 work together to form the refrigeration cycle system of the air conditioning module. Since the working principle of this air conditioning module is the same as that of the prior art, it will not be described in detail here.

[0074] During operation, the condensate produced by the condenser 19 drips onto the air conditioner base plate and collects in the water collection box 18 under the drainage of the base plate. There are two ways to handle the condensate in the water collection box 18. One way is for the user to remove the water collection box 18 and pour out the condensate directly when the condensate reaches a certain amount. The other way is to place the water collection box 18 below the condenser 19 and install a water pump motor inside the water collection box 18. The water pump motor is equipped with fan blades, which can spray the condensate onto the fins of the condenser 19, thereby cooling the condenser 19 and realizing the secondary utilization of the condensate.

[0075] Furthermore, a converging structure 11 is provided inside the air handling unit 2. The converging structure 11 is located between the inner wall of the air handling unit 2 and the fan housing 303 of the fan 3. A converging zone 12 is formed between the converging structure 11 and the inner wall of the air handling unit 2. The air handling unit 2 has a hot air inlet 201. The air inlet of the converging zone 12 is connected to the hot air inlet 201. The air outlet of the converging zone 12 is connected to the hot air inlet 7.

[0076] In order to guide the hot air flow entering the air handling unit 2, a flow-concentrating structure 11 is provided inside the air handling unit 2. The flow-concentrating structure 11 is a plate-shaped structure, and the shape of the plate-shaped structure is adapted to the internal space of the air handling unit 2. The flow-concentrating structure 11 extends from the hot air inlet 201 of the air handling unit to the hot air inlet area 7.

[0077] like Figure 3 As shown, the converging structure 11 is disposed between the inner wall of the air handling unit 2 and the fan housing 303 of the fan 3. A converging zone 12 is formed between the converging structure 11 and the inner wall of the air handling unit 2. The air inlet of the converging zone 12 is connected to the hot air inlet 201 of the air handling unit, and the air outlet of the converging zone 12 is connected to the hot air inlet zone 7, thereby guiding the hot airflow. By setting the converging structure 11 and the converging zone 12, an independent channel is provided for the hot airflow blown out by the condenser impeller 1901 of the air conditioning module, reducing the disturbance between the hot airflow and the oil fume airflow, and guiding the hot airflow to the second side 302 of the fan, thus playing a guiding role in the hot airflow.

[0078] Specifically, in the air conditioning module, when the condenser 19 is working, the condenser impeller 1901 absorbs the heat it generates, forming a hot air flow. The hot air flow passes through the hot air inlet 201 of the air handling unit and the convergence zone 12 from the condenser volute outlet, and enters the fan 3 from the hot air inlet zone 7 of the second side of the fan 302. Then, the hot air flow follows the oil fume flow through the fan outlet 306 and the air handling unit outlet 202, and enters the smoke exhaust channel 20 to be discharged outside the machine.

[0079] In this embodiment, the converging structure 11 is the sidewall of the hot air inlet area 7 away from the oil fume inlet area 6. Therefore, one end of the second separator 5 is connected to the first separator 4, and the other end is connected to the converging structure 11.

[0080] like Figure 6As shown in the accompanying drawings, the heat dissipation and smoke exhaust processes of the smoke extraction equipment in this embodiment, as well as the working processes of the first partition 4 and the second partition 5, will be described below:

[0081] When the smoke hood is started, the first partition 4 is in its initial position. In this embodiment, the initial position of the first partition 4 is set at the middle position of the guide rail 10.

[0082] When only the range hood module is on, the air conditioner condenser 19 is not activated and there is no need to exhaust hot airflow. At this time, the measurement value of the wind speed sensor 16 is 0, and the drive unit 9 controls the first separator 4 to move along the x-direction. Figure 3 At the far left of the viewpoint, the area of ​​the fume inlet zone 6 is the largest, while the area of ​​the hot air inlet zone 7 is the smallest, ensuring that the fume is fully exhausted. Moreover, due to the setting of the first separator 4, the fume inlet zone 6 is prevented from entering the hot air inlet zone 7 and then the exhaust duct of the air conditioning module, thus preventing the fume from polluting the air module.

[0083] When only the air conditioning module is on, the turbine 304 will run at low speed. At this time, the function of the turbine 304 is to absorb the hot airflow discharged from the condenser 19 and send it to the exhaust duct 20. At this time, the wind speed sensor 16 will detect the value and control the first separator 4 to move along the x' direction. Figure 3 At the far right of the viewpoint, the area of ​​the hot air inlet zone 7 is the largest, while the area of ​​the oil fume inlet zone 6 is the smallest, to ensure that the hot air is fully exhausted.

[0084] When the range hood module and the air conditioning module are turned on simultaneously, the back of the turbine 304 (second side 302 of the fan) receives both oil fume and hot air flow. The system determines whether the hot air flow speed measured by the wind speed sensor 16 is greater than a preset value V0. If so, the drive unit 9 controls the first separator 4 to move, reducing the area of ​​the oil fume inlet zone 6 and increasing the area of ​​the hot air inlet zone 7, thereby stopping the first separator 4 at a stop position corresponding to that wind speed range. If not, the drive unit 9 controls the first separator 4 to move, increasing the area of ​​the oil fume inlet zone 6 and decreasing the area of ​​the hot air inlet zone 7, thereby stopping the first separator 4 at a stop position corresponding to that wind speed range. This ensures that the exhaust effect of the range hood is not affected under different hot air emission volumes, providing more airflow for the exhaust process while meeting heat dissipation requirements.

[0085] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
