Description

Technical Field

[0001] The utility model relates to an oil fume extractor, in particular to a refrigerating type oil fume extractor. Background Art

[0002] In order to improve the user cooking experience, various refrigerating type oil fume extractors have been invented. The refrigerating type oil fume extractor adds an air conditioner component on the basis of the oil fume extractor platform. The compressor, condenser and evaporator are connected through a refrigerant pipeline. The refrigerating type oil fume extractor can not only realize all functions of the oil fume extractor, but also realize the functions of the air conditioner. Since the condenser of the air conditioner component is integrated in the oil fume extractor, the heat dissipation effect of the condenser is not good, which affects the air conditioner performance. In addition, during the use of the air conditioner and oil fume extractor, condensate will condense on the surface of the evaporator of the air conditioner component. The existing refrigerating type oil fume extractors usually transport the condensate to the condenser through a liquid distributor. Although the condensate can be used to cool the condenser to improve its heat dissipation effect, when the condensate flows through the surface of the condenser, the unconsumed condensate will still drip from the condenser, which will affect the reliability of the oil fume extractor. Moreover, the condensate is in the oil fume passage. After the air conditioner works for a long time, the water treatment capacity will be greatly reduced. For example, the "A Liquid Distributor and an Air Conditioner Type Oil Fume Extractor Applied with the Liquid Distributor" disclosed in the Chinese utility model patent with the patent number 202121615051.7 (the authorized announcement number is CN215863614U). The condenser and liquid distributor of this air conditioner type oil fume extractor are arranged in the smoke exhaust passage, and the evaporator is arranged in the air outlet passage. The condensate condensed on the surface of the evaporator flows into the inner part of the pipe body of the liquid distributor and flows from the water outlet of the liquid distributor to the condenser. If the condensate is discharged by an external discharge method, it is necessary to rely on the air conditioner drainage pipe outside the kitchen. Usually, a hole is drilled in the wall for external discharge or the condensate is introduced into the sewer through a pipe, which increases the installation cost. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a refrigerating type oil fume extractor capable of recycling and utilizing air conditioner condensate water in view of the above-mentioned current situation of the prior art.

[0004] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A refrigerating range hood, which includes an oil fume suction module, a compressor, a heat dissipation module and a refrigeration module.

It is characterized in that: A fan frame top plate is installed on the top of the fan frame. A water storage tank is formed on the fan frame top plate. The condenser is arranged above the water storage tank. The bottom of the water storage tank has a drain port. A condensate collection and conveying device is arranged outside the fan frame. The condensate condensed on the surface of the evaporator is collected by the condensate collection and conveying device and then conveyed to the condenser. The condensate that is not consumed by the condenser flows into the water storage tank and returns to the condensate collection and conveying device through the drain port.

[0005] The refrigeration module and the heat dissipation module can be installed at multiple different positions on the fan frame. Preferably, the refrigeration module is arranged on the right side of the fan frame, and the heat dissipation module is arranged above the fan frame.

[0006] The fan frame top plate can have multiple different structures. The fan frame top plate includes a left horizontal top plate and a right inclined top plate that is obliquely downwardly inclined from the right edge of the left horizontal top plate. The water storage tank is arranged at the lowest position of the right inclined top plate. The heat dissipation fan and the condenser are both arranged above the right inclined top plate, and the heat dissipation fan is located on the left side of the condenser.

[0007] In order to install the air outlet hood on the fan frame top plate, an air outlet hood is installed on the left horizontal top plate, and the air outlet of the oil fume suction fan faces the air inlet of the air outlet hood.

[0008] The condenser collection and conveying device can have various structures. Preferably, the condensate collection and conveying device includes a water receiving box and a water pump installed on the water receiving box. The water receiving box has a water inlet, a water outlet and a water return port. The condensate flowing down from the surface of the evaporator flows into the water receiving box through a water inlet pipe and the water inlet. Under the action of the water pump, the condensate in the water receiving box is conveyed to the condenser through the water outlet and a water outlet pipe. The drain port of the water storage tank is connected to the water return port through a water return pipe.

[0009] In order to facilitate the smooth flow of the condensate on the evaporator and the condensate that is not consumed by the condenser into the water receiving box, the evaporator and the condenser are arranged above the water receiving box.

[0010] In order to smoothly blow cold air on the front of the range hood, the indoor fan is arranged below the evaporator. An air outlet module is opened on the front of the range hood. The air outlet of the indoor fan is connected to the air outlet module through an air outlet channel.

[0011] Further preferably, the range hood includes an upper box body and a lower box body.

The air outlet module is arranged on the front surface of the lower box body, and an oil fume suction port communicating with the air inlet of the oil fume suction fan is formed on the lower box body.

[0012] As a preference of any of the above solutions, the oil fume suction fan, the heat dissipation fan and the indoor unit fan are all centrifugal fans.

[0013] There can be various positional relationships among the oil fume suction fan, the heat dissipation fan and the indoor unit fan. Preferably, the central axes of the impellers of the oil fume suction fan, the heat dissipation fan and the indoor unit fan are all horizontally arranged. Moreover, the central axis of the impeller of the oil fume suction fan and the central axis of the impeller of the indoor unit fan are parallel to each other and perpendicular to the central axis of the impeller of the heat dissipation fan.

[0014] Compared with the prior art, the advantages of the present utility model are as follows: A water storage tank is formed on the top plate of the fan frame of the refrigerating range hood. Since the condenser is arranged above the water storage tank, the condensed water condensed on the surface of the evaporator is collected by the condensed water collection and conveying device and then conveyed to the condenser. The condensed water not consumed by the condenser flows into the water storage tank and then flows back to the condensed water collection and conveying device through the drain port, thereby realizing the recycling and utilization of the condensed water. Moreover, after the water storage tank is arranged on the top plate of the fan frame, the condensed water can be collected to prevent the condensed water from overflowing.

[0021] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0022] As Figures 1 to 6As shown in the figure, the present embodiment includes an oil fume extraction module 1, a compressor 2, a heat dissipation module 3, and a refrigeration module 4.

[0023] In this embodiment, taking Figure 3 the direction indicated by arrow A in the figure as the right direction, the heat dissipation module 3 is installed above the fan frame 11, and the refrigeration module 4 is installed on the right side of the fan frame 11. Usually, the compressor 2 can also be installed on the right side of the fan frame 11. The heat dissipation module 3 is integrated on the range hood, without the need for an outdoor unit of the air conditioner, and is convenient to install. The refrigeration module 4 is installed on the side of the fan frame 11, without affecting the air duct and structural layout of the range hood. In addition, the refrigeration module 4 can also be installed on the left side of the fan frame 11.

[0024] The range hood of this embodiment includes an upper box body and a lower box body 10 installed at the bottom of the upper box body. The oil fume extraction module 1, the compressor 2, the heat dissipation module 3, and the refrigeration module 4 are arranged inside the upper box body. An air outlet module 8 is installed on the front surface of the lower box body 10. The indoor unit fan 42 is arranged below the evaporator 41. The air outlet of the indoor unit fan 42 is connected to the air outlet module 8 through an air outlet channel 9. An oil fume suction port 101 communicating with the air inlet of the oil fume extraction fan 12 is opened on the lower box body 10. When the range hood is started and the refrigeration mode is turned on, under the action of the oil fume extraction fan 12, the oil fume is discharged from the oil fume suction port 101 and through the oil fume extraction fan 12. The cold air blown out from the indoor unit fan 42 blows towards the air outlet module 8 through the air outlet channel 9, and finally blows out the cold air through the air outlet of the air outlet module 8. The high-temperature air generated after heat exchange by the condenser 31 can be directly discharged to the outside of the range hood through the heat dissipation fan 32, or can be discharged into the oil fume extraction fan 12 through the heat dissipation fan 32, and finally discharged together with the oil fume through the oil fume extraction fan 12.

[0025] The oil fume extraction fan 12, the heat dissipation fan 32, and the indoor unit fan 42 of this embodiment are all centrifugal fans. The impeller central axes of the oil fume extraction fan 12, the heat dissipation fan 32, and the indoor unit fan 42 are all horizontally arranged. Moreover, the impeller central axis of the oil fume extraction fan 12 and the impeller central axis of the indoor unit fan 42 are parallel to each other and perpendicular to the impeller central axis of the heat dissipation fan 32.

[0026] At the top of the fan frame 11, a top plate 13 of the fan frame is installed. The top plate 13 of the fan frame includes a left horizontal top plate 131 and a right inclined top plate 132 that is inclined obliquely downward from the right edge of the left horizontal top plate 131. An air outlet hood 7 is installed on the left horizontal top plate 131, and the air outlet of the oil fume suction fan 12 faces the air inlet of the air outlet hood 7. At the lowest point of the right inclined top plate 132, a water storage tank 130 is formed. The bottom of the water storage tank 130 has a drain port 1300. The water storage tank 130 can be used to collect condensed water to prevent the condensed water from overflowing. The heat dissipation fan 32 and the condenser 31 are both arranged above the right inclined top plate 132, and the heat dissipation fan 32 is arranged on the left side of the condenser 31, and the condenser 31 is arranged above the water storage tank 130. The top plate 13 of the fan frame can seal the oil fume passage, fix the heat dissipation module 3, and can also collect condensed water, integrating multiple functions into one.

[0027] A condensed water collection and conveying device 6 is provided outside the fan frame 11. The condensed water collection and conveying device 6 specifically includes a water receiving box 61 and a water pump 62 installed on the water receiving box 61. The evaporator 41 and the condenser 31 are both arranged above the water receiving box 61. The water receiving box 61 has a water inlet 611, a water outlet 612, and a water return port 613. The condensed water flowing down from the surface of the evaporator 41 flows into the water receiving box 61 through the water inlet pipe 63 and the water inlet 611. Under the action of the water pump 62, the condensed water in the water receiving box 61 is conveyed to the condenser 31 through the water outlet 612 and the water outlet pipe 64. The drain port 1300 of the water storage tank 130 is connected to the water return port 613 through a water return pipe 65. That is, when working in the refrigeration mode, the condensed water condensed on the surface of the evaporator 41 is collected by the water receiving box 61 and then conveyed to the top of the condenser 31 by the water pump 62. The water flows through the high-temperature condenser fins from the top. Part of the condensed water is heated and evaporated, and the unevaporated condensed water is collected in the water storage tank 130 at the bottom of the top plate 13 of the fan frame and flows back to the water receiving box 61 through the water return pipe 65. In this way, the condensed water is circulated and evaporated until it is consumed, avoiding the external discharge of the condensed water.
