Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a refrigeration type range hood. Background Art

[0002] In order to improve the user's cooking experience, people have invented various refrigeration range hoods. Refrigeration range hoods add air conditioning components on the basis of the range hood platform, that is, the compressor, heat dissipation module and refrigeration module are integrated on the range hood platform. The heat dissipation module includes a heat dissipation fan and a condenser, and the refrigeration module includes an internal fan and an evaporator. In order to reduce the impact on the range hood's oil fume absorption ability, the heat dissipation module in the refrigeration range hood often uses low wind speed to dissipate heat from the condenser. At low wind speeds, the temperature of the condenser can often reach above 60°C, and the wind that disperses the condenser will pass through the heat dissipation motor, continuously heating the heat dissipation motor, causing the temperature rise of the heat dissipation motor to be too high, thereby affecting the performance of the heat dissipation motor and reducing the heat dissipation air volume. For the entire refrigeration system, the heat dissipation air volume is small, thereby reducing the cooling capacity and stability of the entire machine. In order to solve the impact of the temperature rise of the heat dissipation motor on performance and improve reliability, it can be solved by increasing costs and increasing the maximum temperature resistance of the heat dissipation motor, but this solution is costly and still has hidden dangers. Alternatively, the control board of the heat dissipation motor can be arranged outside the heat dissipation module, but the heat in the heat dissipation module will affect the magnetic poles inside the motor, causing excessive temperature or even demagnetization, thereby affecting the motor performance. In summary, further improvements need to be made to the existing refrigeration range hoods. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a refrigeration type range hood in which the heat of the heat dissipation module will not affect the motor driving the heat dissipation fan in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a refrigeration type range hood, including a range hood module, a compressor, a heat dissipation module, and an indoor module, the heat dissipation module includes a condenser and a heat dissipation fan, the indoor module includes an evaporator and an indoor fan, the compressor, condenser and evaporator are connected through a refrigerant pipeline, and is characterized in that: the heat dissipation module and the indoor module are isolated from each other, a dual-axis motor is provided on the outside of the heat dissipation module, the indoor fan is installed at the first output end of the dual-axis motor, and the heat dissipation fan is installed at the second output end of the dual-axis motor.

[0005] The dual-axis motor can be located in a plurality of different positions. Preferably, the dual-axis motor is arranged on the internal machine module. Such an arrangement can reduce the influence of the hot air of the heat dissipation module on the motor.

[0006] As another preferred solution, the first output end of the dual-axis motor is connected to the heat dissipation fan through a first transmission mechanism, and the second output end of the dual-axis motor is connected to the indoor fan through a second transmission mechanism.

[0007] Further preferably, the range hood further comprises a controller, which can control the on and off of the first transmission mechanism and the second transmission mechanism in different working modes of the range hood, and further control the working states of the heat dissipation fan and the indoor fan. In this way, the transmission mechanism can be disconnected or connected with the indoor fan and the heat dissipation fan according to different working modes, which can meet different usage scenarios.

[0008] The heat dissipation module and the internal unit module can be arranged at multiple different positions of the range hood. Preferably, the heat dissipation module and the internal unit module are arranged above the range hood module, and the heat dissipation module and the internal unit module are arranged adjacent to each other left and right or front and back.

[0009] The compressor can be arranged at a plurality of different positions. Preferably, the fume extraction module includes a fume extraction fan, and the compressor is arranged on the side of the fume extraction fan and is located below the heat dissipation module or the internal unit module.

[0010] In order to discharge the heat of the heat dissipation module through the oil fume suction fan, the oil fume suction module has an oil fume channel, and the air outlet of the heat dissipation module is connected to the oil fume channel.

[0011] Further preferably, the oil fume suction module includes an oil fume suction fan, the oil fume passage includes an inlet passage arranged upstream of the air inlet of the oil fume suction fan and an exhaust passage arranged downstream of the air outlet of the oil fume suction fan, and the air outlet of the heat dissipation module is connected to the inlet passage. With this arrangement, the oil fume suction fan produces a suction effect on the airflow at the air outlet of the heat dissipation module, which can prevent the oil fume airflow from entering the heat dissipation module from the air outlet of the heat dissipation module and contaminating the condenser.

[0012] The range fumes suction fan comprises a main air inlet and an auxiliary air inlet, and the air outlet of the heat dissipation module is connected to the auxiliary air inlet. With such arrangement, the heat dissipation airflow will not interfere with the main air inlet channel of the range fumes suction fan, thus ensuring the range fumes suction effect.

[0013] Further preferably, the main air inlet is a rear air inlet of the range fumes exhaust fan, and the auxiliary air inlet is a front air inlet of the range fumes exhaust fan.

[0014] Compared with the prior art, the advantages of the utility model are that the heat dissipation module and the indoor unit module of the refrigeration type range hood share a dual-axis motor. Driven by the dual-axis motor, the heat dissipation fan and the indoor unit fan work simultaneously, thereby reducing the cost of the entire machine. In addition, the heat dissipation module and the indoor unit module are isolated from each other, and the dual-axis motor is arranged outside the heat dissipation module, which can reduce the influence of the hot air from the heat dissipation module on the motor, will not cause the motor temperature to rise too high, will not reduce the motor working performance, and thus ensure the refrigeration stability of the entire system.

The compressor 2, the condenser 31 and the evaporator 41 are connected through a refrigerant pipeline 5. The compressor 2, the heat dissipation module 3 and the indoor unit module 4 constitute a refrigeration system, and its working principle is the same as that of the existing air conditioner, which will not be described in detail here.

[0023] The oil fume extraction module 1 includes an oil fume extraction fan 11, which adopts a front and rear double air inlet structure, that is, the oil fume extraction fan 11 includes a main air inlet 14 and an auxiliary air inlet 15. Figure 2The direction indicated by the middle arrow B is forward, the main air inlet 14 is the rear air inlet, and the auxiliary air inlet 15 is the front air inlet. The fume extraction module 1 has an oil fume passage, which includes an inlet passage 12 arranged upstream of the air inlet of the fume extraction fan 11 and an exhaust passage 13 arranged downstream of the air outlet of the fume extraction fan 11.

[0025] In order to avoid the heat of the heat dissipation module 3 and the cold of the indoor module 4 from interfering with each other, the heat dissipation module 3 and the indoor module 4 are isolated from each other.
