Description

Technical Field

[0001] This utility model relates to range hoods, and more particularly to a condenser heat dissipation system for a refrigeration range hood. Background Technology

[0002] Various refrigerated range hoods are disclosed in the prior art. These hoods add an air conditioning component to the existing range hood platform. The compressor, condenser, and evaporator are connected via refrigerant piping. The refrigerated range hood can perform both the functions of a range hood and an air conditioning function. The condenser of existing refrigerated range hoods typically dissipates heat by exhausting the condenser into a common flue through an exhaust duct. For example, the "Kitchen Air Conditioning System" disclosed in Chinese Invention Patent No. 201811150307.4 (Authorization Announcement No. CN 110966676 B) has a condenser installed in the air outlet duct downstream of the range hood fan. The air exhausted by the range hood fan is blown towards the condenser to remove the heat from the refrigerant, thus eliminating the need for an additional outdoor unit. However, in this solution, the air exhausted by the range hood fan is blown towards the condenser. Since the air contains many oil fume particles, in order to keep the condenser surface clean, an additional electrostatic device is often needed to filter these fine particles, which increases costs and introduces the risk of errors. Moreover, the electrostatic device cannot completely filter oil stains. For example, the Chinese utility model patent No. 202420143790.8 (authorization announcement No. CN 221881576 U) discloses a "Refrigeration-type Range Hood." This refrigeration-type range hood uses a vent in the volute of a cooling fan to dissipate heat from the condenser, and then the hot air is vented to the exhaust fan outdoors. This requires an additional cooling fan, increasing cost and reducing reliability. Moreover, due to space constraints, the cooling fan is generally small, providing limited airflow. Therefore, a larger condenser is needed to increase heat dissipation, further increasing condenser cost. In conclusion, further improvements are needed to the condenser cooling system of existing refrigeration-type range hoods. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a condenser heat dissipation system for a refrigeration range hood that can effectively dissipate heat and meet the cooling demand of a large amount of cooling capacity, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a condenser heat dissipation system for a refrigeration range hood, including a fan frame, and a fan system installed inside the fan frame, characterized in that: the fan system includes a first fan and a second fan connected in parallel, a ventilation opening is opened on the side wall of the fan frame, a valve plate is installed at the ventilation opening, a heat dissipation duct is provided outside the fan frame, and a condenser is provided inside the heat dissipation duct. When the valve plate is closed, the heat dissipation duct is isolated from the fan system. When the valve plate is open, the heat dissipation duct is connected to the fan system through the ventilation opening.

[0005] The first and second fans can have various structures. Preferably, both the first and second fans are vertically arranged centrifugal fans, and the central axis of the impeller of the first fan and the central axis of the impeller of the second fan are located on the same straight line and perpendicular to the left and right side walls of the fan frame.

[0006] In order to facilitate the first fan to remove the heat in the heat dissipation duct, the ventilation opening is located on the side wall of the fan frame opposite to the air inlet of the first fan.

[0007] To prevent leakage of cooling airflow after the valve plate is opened, the cooling airflow flowing out of the cooling duct is blocked by the valve plate and can only flow into the air inlet of the first fan when the valve plate is open.

[0008] The condenser can be distributed in various ways. As a preferred embodiment, the condenser includes a first condenser and a second condenser, which are vertically arranged and symmetrically positioned on the left and right sides of the heat dissipation duct. The heat dissipation duct has a left air inlet and a right air inlet. The left air inlet faces the first condenser, and the right air inlet faces the second condenser. With this arrangement, the heat dissipation duct draws air from the left and right sides, which can alleviate the problem of poor air intake in ceilings and cabinets to some extent.

[0009] As another preferred embodiment, the condenser has a U-shaped structure with its opening facing downwards. The heat dissipation duct has a left air inlet, a right air inlet, and a top air inlet, with the left, right, and top air inlets facing their respective sides of the condenser. This configuration increases the condenser's heat exchange area and, by drawing air in from the left, top, and right, significantly improves heat exchange capacity.

[0010] As another preferred embodiment, the condenser is arranged at an angle relative to the vertical plane, and the heat dissipation duct has a left-side air inlet and a top air inlet. This arrangement allows for greater space utilization of the condenser, enabling a larger condenser size and increased heat exchange area.

[0011] As another preferred embodiment, the condenser is vertically arranged and close to the left side wall of the heat dissipation duct, which has a left-side air inlet facing the side of the condenser.

[0012] More preferably, there is one condenser, or at least two condensers arranged vertically adjacent to each other.

[0013] The first and second fans can have various exhaust structures. As a preferred option, the air outlets of the first and second fans are equipped with three-way exhaust hoods. The three-way exhaust hoods have a first inlet, a second inlet, and an outlet. The first inlet is connected to the air outlet of the first fan, and the second outlet is connected to the air outlet of the second fan.

[0014] As another preferred embodiment, the first fan is equipped with a first exhaust pipe at its outlet, and the second fan is equipped with a second exhaust pipe at its outlet, with the first exhaust pipe and the second exhaust pipe being independent of each other.

[0015] Compared with the prior art, the advantages of this utility model are as follows: the fan system of this cooling range hood adopts a dual fan system. In cooling mode, the valve plate is opened, and the heat dissipation duct is connected to the air inlet of the fan system through the ventilation port. The fan system can be used to dissipate heat from the condenser in the heat dissipation duct, which is conducive to achieving greater cooling capacity and improving air conditioning energy efficiency. In addition, the dual fan system is also conducive to improving the smoke extraction effect. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1:

[0023] like Figure 1As shown, the refrigerated range hood of this embodiment includes a fan frame 1, inside which a fan system is installed. The fan system includes a first fan 2 and a second fan 3 connected in parallel. Both the first fan 2 and the second fan 3 are vertically arranged centrifugal fans, and their performance can be exactly the same or similar. The impeller central axis of the first fan 2 and the impeller central axis of the second fan 3 are located on the same straight line and perpendicular to the left and right side walls of the fan frame 1. A three-way exhaust hood 13 is installed at the air outlet of the first fan 2 and the air outlet of the second fan 3. The three-way exhaust hood 13 has a first inlet, a second inlet, and an outlet. The first inlet is connected to the air outlet of the first fan 2, and the second outlet is connected to the air outlet of the second fan 3. Alternatively, a first exhaust pipe can be installed at the air outlet of the first fan 2, and a second exhaust pipe can be installed at the air outlet of the second fan 3. The first exhaust pipe and the second exhaust pipe are independent of each other.

[0024] A ventilation opening 11 is provided on the fan frame 1, located on the side wall of the fan frame 1 opposite to the air inlet of the first fan 2. A valve plate 4 is installed at the ventilation opening 11. A heat dissipation duct 5 is provided on the outside of the fan frame 1, and a condenser 6 is installed inside the heat dissipation duct 5. A compressor 8 and an indoor unit module (not shown in the figure) are also installed on the outside of the fan frame 1. The compressor 8, condenser 6, and indoor unit module constitute an air conditioning assembly. Its working principle can be referred to the existing refrigeration range hood, and will not be described in detail here.

[0025] In this embodiment, the condenser 6 includes a first condenser 61 and a second condenser 62 that are vertically arranged and symmetrically arranged on the left and right sides of the heat dissipation duct 5. The heat dissipation duct 5 has a left air inlet 51 and a right air inlet 52. The left air inlet 51 faces the first condenser 61 and the right air inlet 52 faces the second condenser 62.

[0026] When the range hood is turned on, the valve plate 4 is closed, the vent 11 is closed, and the heat dissipation duct 5 is isolated from the fan system. The fumes enter the first fan 2 and the second fan 3 and are discharged outward. At this time, the working mode is the same as that of a normal range hood. The condenser 6 is completely separated from the air inlets of the first fan 2 and the second fan 3 by the valve plate 4, so the fumes will not pollute the condenser 6.

[0027] When the air conditioner is turned on, the first fan 2 is turned on, the valve plate 4 is opened, the vent 11 is opened, and the heat dissipation duct 5 is connected to the fan system through the vent 11. Under the obstruction of the valve plate 4, the heat dissipation airflow from the heat dissipation duct 5 can only flow into the air inlet of the first fan 2. The heat of the condenser 6 is discharged to the outside through the first fan 2. At this time, the first fan 2 provides airflow for the condenser 6 to dissipate heat.

[0028] When both the air conditioner and the range hood are turned on, both the first fan 2 and the second fan 3 are turned on, the valve plate 4 is open, the vent 11 is open, and the heat dissipation duct 5 is connected to the fan system through the vent 11. Under the obstruction of the valve plate 4, the heat dissipation airflow from the heat dissipation duct 5 can only flow into the air inlet of the first fan 2. The heat of the condenser 6 is discharged to the outside through the first fan 2. At this time, the first fan 2 is used to provide airflow for heat dissipation of the condenser 6 and also to provide airflow for fume extraction, discharging the heat and fumes of the condenser 6 into the common flue. At the same time, the second fan 3 provides airflow for fume extraction. In this way, the dual-fan system can achieve large-capacity cooling while maintaining a constant fume extraction effect, resulting in good cooling performance.

[0029] Example 2:

[0030] like Figure 2 As shown, the condenser 6 in this embodiment has a U-shaped structure with its opening facing downwards. The heat dissipation duct 5 has a left air inlet 51, a right air inlet 52, and a top air inlet 53, which face the corresponding sides of the condenser 6. Increasing the heat exchange area of ​​the condenser 6 and drawing air from the left, right, and top significantly improves the condenser's heat dissipation effect and enhances the air conditioning's energy efficiency. The remaining structure of this embodiment is the same as in Embodiment 1 and will not be described again here.

[0031] Example 3:

[0032] like Figure 3 As shown, in this embodiment, the condenser 6 is arranged at an angle relative to the vertical plane, and the heat dissipation duct 5 has a left air inlet 51 and a top air inlet 53. With the condenser 6 placed at an angle, more space can be utilized, allowing for a larger condenser 6 size, increasing the heat exchange area, and improving the heat dissipation effect. The remaining structure of this embodiment is the same as in Embodiment 1, and will not be described again here.

[0033] Example 4:

[0034] like Figure 4 As shown, in this embodiment, the condenser 6 is vertically arranged and close to the left side wall of the heat dissipation duct 5. The heat dissipation duct 5 has a left air inlet 51 facing the side of the condenser 6. The left air inlet 51 directly faces the side of the condenser 6, which helps to improve the heat dissipation effect of the condenser 6. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be described again here.

[0035] Example 5:

[0036] like Figure 5 As shown, the condenser 6 in this embodiment includes a vertically arranged upper condenser 63 and a lower condenser 64, with the upper condenser 63 located above and adjacent to the lower condenser 64. The remaining structure of this embodiment is the same as that of Embodiment 4, and will not be described again here.

[0037] Furthermore, the specific form of the embodiments is not limited to the above embodiments, and other different structures and arrangements can also be adopted.

[0038] This range hood can be controlled by a voice module, which is equipped with a control module, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.
