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 cooking experience, people have invented various refrigeration range hoods, which can realize all the functions of range hoods and the functions of air conditioners. The condensed water of refrigeration range hoods on the market is often discharged externally by drilling holes in the wall or introducing the condensed water into the sewer pipe through pipes for external discharge. It does not have the ability to process the condensed water independently and cannot consume the condensed water generated during its own refrigeration, thereby increasing the installation cost. Although the prior art also discloses a structure in which a liquid distributor is installed on the condenser, and condensed water is transported to the liquid distributor to dissipate heat and cool the condenser, such as the "A Kitchen Air Conditioning System" disclosed in the Chinese Utility Model Patent No. 2021b2324959.9 (Authorization Announcement No. CN216308056 U). The condenser of the kitchen air conditioning system is arranged in the smoke exhaust channel, and the evaporator is arranged in the air outlet channel. The condensed water collected by the condensed water collection device is transported to the surface of the condenser through the liquid distributor. The liquid distributor has a liquid distribution pipe arranged in a circuitous manner on the surface of the condenser. During operation, the oil smoke can take away the heat of the condenser, and the condensed water flows through the liquid distribution pipe arranged in a circuitous manner on the surface of the condenser, which effectively dissipates heat from the condenser, reduces the temperature of the condenser surface, improves the condensation performance, improves the air conditioning energy efficiency and refrigeration capacity, and realizes the effective utilization of condensed water. However, the liquid distributor will be unstable due to the influence of installation angle and material. Sometimes the condensed water on the distributor is uneven, resulting in poor heat exchange and evaporation consumption with the condenser surface. Therefore, when the weather is humid, it is difficult to process the water and it still needs to be discharged.

[0003] In addition, there are also range hoods in the prior art that use controlled condensed water to clean the volute, such as the "A Kind of Air-conditioning Range Hood" disclosed in the Chinese utility model patent with patent number 202220018984.6 (authorization announcement number CN 217004584 U). The range hood has a water collection box for collecting condensed water condensed on the surface of the evaporator, and a steam generator is installed inside the housing. The water collection box is connected to the water inlet of the steam generator through a water outlet pipe, and the steam outlet of the steam generator is connected to the air duct inside the range hood. After the air-conditioning condensed water evaporates through the steam generator, it enters the range hood, and the high-temperature water vapor passes through the fan impeller to clean the impeller. Although the air-conditioning range hood uses air-conditioning condensed water to clean the fan impeller, it is necessary to use the steam generator inside the housing to heat the condensed water, which is not only complicated in structure, but also increases the cost, and the heat generated by the condenser when the air conditioner is working is not effectively utilized.

[0004] In summary, there is a need to further improve the existing refrigeration type range hoods. Utility Model Content

[0009] Further preferably, the air outlet of the guide channel is in a circular shape and the air outlet direction is toward the inner side of the range fumes exhaust fan. In this way, under the negative pressure of the range fumes exhaust fan, the hot air blown out of the guide channel can be smoothly sucked into the range fumes exhaust fan.

[0010] In order to make the arrangement of the heat dissipation fan and the condenser more reasonable, the condenser and the heat dissipation fan are both arranged above the range fumes suction fan, and along the air flow direction, the condenser is arranged upstream of the heat dissipation fan.

[0011] In order to smoothly transport the condensed water to the heat dissipation fan, a water pump and a water outlet pipe are also included. The water inlet end of the water outlet pipe is connected to the water outlet of the water pump, and the water outlet end of the water outlet pipe is connected to the interior of the heat dissipation fan. Under the action of the water pump, the condensed water in the water receiving box is transported to the interior of the heat dissipation fan through the water outlet pipe.

[0014] The heat dissipation module and the internal unit module may have a plurality of mounting structures. Preferably, the heat dissipation module and the internal unit module are arranged adjacent to each other on the left and right.

[0015] In order to allow cold air to be blown out through the indoor air outlet, an indoor air outlet is opened on the upper box body or the lower cavity, and the air outlet of the indoor fan is fluidly connected with the indoor air outlet through an air guide duct.

[0016] Compared with the prior art, the advantages of the utility model are: the refrigeration type range hood is equipped with a double-layer guide ring at the edge of the air inlet of the range fume fan, and the air outlet of the heat dissipation fan is connected with the air inlet of the range fume fan through the guide channel inside the guide ring. When working in the refrigeration mode, on the one hand, the heat of the condenser is blown out by the heat dissipation fan and enters the range fume fan, and the hot air blown into the volute can clean the oil stains on the inner wall of the volute, and the fan volute is self-cleaned to achieve effective utilization of the hot air. On the other hand, the condensed water generated on the surface of the evaporator is transported to the inside of the heat dissipation fan, and is atomized by the heat dissipation fan impeller and then discharged into the double-layer guide ring. Since the volume of the double-layer guide ring cavity is small, the hot air flow rate is fast, and the temperature is high, the atomized condensed water evaporates quickly, completely solving the problem of condensed water discharge.

The compressor 2, the condenser 32 and the evaporator 42 constitute an air conditioning component, and its specific working principle is the same as that of the existing air conditioner, which will not be described in detail here.

[0026] The heat dissipation module 4 of this embodiment is arranged outside the fan frame 21, and the condenser 41 and the heat dissipation fan 42 are both arranged above the range fume exhaust fan 22. Along the air flow direction, the condenser 41 is arranged upstream of the heat dissipation fan 42. The heat dissipation fan 42 and the range fume exhaust fan 22 of this embodiment are both centrifugal fans. A guide ring 7 is installed at the edge of the air inlet of the range fume exhaust fan 22. The guide ring 7 is a double-layer structure. A guide channel 71 is formed inside the guide ring 7. The air outlet of the heat dissipation fan 42 faces the air inlet of the guide channel 71 and is connected with the air inlet of the range fume exhaust fan 22 through the guide channel 71. In order to make the diversion smoother, a guide cover 8 is installed at the air inlet of the guide ring 7. The air inlet of the guide channel 71 is connected with the air outlet of the heat dissipation fan 42 through the guide cover 8. The air outlet of the guide channel 71 is in a circular shape and the air outlet direction faces the inner side of the range fume exhaust fan 22.

[0027] A water receiving box 10 is installed in the housing 1. The water receiving box 10 is arranged below the evaporator 51. The evaporator 51 is arranged tilted relative to the vertical plane. The projection of the bottom of the evaporator 51 in the vertical direction falls in the water receiving box 10. When working in the cooling mode, the condensed water condensed on the surface of the evaporator flows into the water receiving box 10. The water inlet end of the water outlet pipe 12 is connected to the water outlet of the water pump 11, and the water outlet end of the water outlet pipe 12 is connected to the inside of the heat dissipation fan 42. Under the action of the water pump 11, the condensed water in the water receiving box 10 is transported to the inside of the heat dissipation fan 42 through the water outlet pipe 12.

[0028] The housing 1 of this embodiment includes an upper box body 1a and a lower cavity 1b arranged at the bottom of the upper box body 1a. The oil fume extraction module 2, the compressor 3, the heat dissipation module 4 and the internal machine module 5 are installed inside the upper box body 1a. The lower cavity 1b is provided with a smoke inlet connected to the air inlet of the oil fume extraction fan 21. The compressor 3 is installed above the lower cavity 1b and is located on the right side of the oil fume extraction fan 21. The internal machine module 5 is arranged above the compressor 3 and is located outside the fan frame 21. The heat dissipation module 4 is located on the left side of the internal machine module 5. The heat dissipation module 4 and the internal machine module 5 may share an air inlet or each may have an independent air inlet.

[0029] The indoor air outlet 13 of the present embodiment is arranged at the upper part of the lower cavity 13 , and the air outlet of the indoor fan 52 is fluidically connected to the indoor air outlet 13 through the air guide duct 9 .

At the same time, the heat dissipation fan 42 generates suction, and the air passes through the condenser 41 to take away the heat, and is discharged into the guide channel 71 of the guide ring 7, and finally enters the volute of the range fumes exhaust fan 22 and is discharged to the outside along with the range fumes exhaust fan 22. The heat of the condenser 41 is blown out by the heat dissipation fan and enters the range fumes exhaust fan 22. The oil smoke will not pollute the condenser 41, which can extend the service life of the condenser 41. In addition, with the structure of the guide ring 7, the heat dissipation air can be smoothly sucked into the range fumes exhaust fan 22, and the hot air blown into the volute can clean the oil stains on the inner wall of the volute, perform self-cleaning of the volute, and realize the effective use of hot air. At the same time, the condensed water generated on the surface of the evaporator 51 is transported to the interior of the heat dissipation fan 42, and is atomized by the impeller of the heat dissipation fan 42 and then discharged into the double-layer structure guide ring 7. Since the double-layer guide ring cavity has a small volume, the hot air flow rate is fast, and the temperature is high, the atomized condensed water evaporates quickly, completely solving the problem of condensed water discharge.
