Description

Technical Field

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

[0002] Various refrigeration-type range hoods are disclosed in the prior art, which can realize all the functions of the range hood and the function of the air conditioner. When working in the air conditioning mode, the oil fume and the condensed water on the condenser are used for heat exchange and evaporation. As the working time increases, oil stains will adhere to the condenser, thereby affecting the adhesion ability of the condensed water on the condenser, thereby reducing the water treatment capacity. When the range hood is turned on at a high gear, the residence time of the condensed water on the condenser is shortened, greatly reducing the evaporation capacity of the condensed water. When the air conditioner is turned on at a high gear, the heat dissipation fan is at the maximum gear, which is easy to bring out the water between the condenser fins, causing water splashing. In addition, it is difficult to avoid the installation error of the range hood. After the whole machine is installed, if the condenser tilts to one side, due to the effect of gravity, the condensed water is easy to fall, and the condensed water has not had time to exchange heat. When the heat dissipation fan is turned on, the water splashing is serious and the condensed water is almost impossible to handle.

[0003] In addition, during daily use of refrigeration range hoods, a large amount of grease will remain on the volute and impeller. After a long period of air drying and solidification, these grease will form a hard grease layer on the volute and impeller, which is very difficult to clean. Traditional range hoods on the market often do not have a cleaning function. Even if a cleaning function is added, it is simply to add a water pump and a heating rod to heat and spray the water added from the outside for cleaning. Additional parts are needed, which reduces the reliability of the whole machine, and the addition of water from the outside increases the complexity. In summary, there is a need for further improvement of existing refrigeration range hoods. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a refrigeration range hood which can prevent condensed water from splashing and utilize condensed water to self-clean the fan volute in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a refrigeration type range hood, including a range hood module, a compressor, a heat dissipation module and an indoor module, the range hood module including a range hood fan, the heat dissipation module and the indoor module are arranged on the outside of the range hood fan, 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, the range hood fan includes a volute, and is characterized in that: the condenser is vertically arranged, an evaporation net is installed on the side wall of the condenser, condensed water condensed on the surface of the evaporator is collected and transported to the top of the condenser, a water storage box is provided below the condenser, a water outlet is provided at the bottom of the water storage box, a water inlet is provided on the volute, the water outlet and the water inlet are connected through a water outlet channel, and a switch that can be turned on when the water amount in the water storage box reaches an appropriate amount is installed at the water outlet.

[0006] Preferably, the switch is a gravity sensing switch. When the amount of water in the water storage box reaches a certain amount, the gravity sensing switch is turned on, and the water in the water storage box flows into the volute of the range hood fan.

[0007] In order to allow the condensed water on the condenser and the evaporation net to flow downward into the water storage box, the evaporation net is attached to the side wall of the condenser, and the vertical projection of the bottom of the condenser and the vertical projection of the bottom of the evaporation net both fall into the water storage box.

[0008] In order to smoothly transport the condensed water to the condenser, a water receiving box is installed under the evaporator. The water receiving box is used to receive the condensed water flowing from the surface of the evaporator. A water outlet pipe is connected between the water receiving box and the condenser. A water pump is installed on the water outlet pipe to transport the condensed water in the water receiving box to the condenser.

[0009] In order to discharge the heat of the condenser to the outside through the fume extractor fan, a vent is opened on the volute ring wall of the fume extractor fan, and the air outlet of the heat dissipation fan can be fluidically connected with the inside of the volute through the vent.

[0010] In order to allow the hot air blown in from the vent to disperse the condensed water entering the volute from the water inlet, the vent is arranged upstream of the water inlet along the airflow direction. In this way, the hot air from the heat dissipation fan blows along the volute ring wall, and the condensed water with a higher temperature after heat exchange in the condenser enters the volute, thereby performing a double combination cleaning of the range hood fan, and the cleaning effect is better.

[0011] In order to prevent the condensed water on the condenser from being directly sucked away by the heat dissipation fan, along the flow direction of the airflow, the evaporation net is arranged downstream of the condenser, and the heat dissipation fan is arranged downstream of the evaporation net.

[0012] It is further preferred that an air guide valve capable of opening and closing the air guide valve is installed at the vent. In this way, when the air guide valve is opened, the air outlet of the heat dissipation fan is connected to the interior of the volute of the range fumes exhaust fan through the vent, and when the air guide valve is closed, the air outlet of the heat dissipation fan is isolated from the interior of the volute of the range fumes exhaust fan.

[0013] Further preferably, the range fumes suction fan and the heat dissipation fan are both centrifugal fans, and the central axis of the impeller of the range fumes suction fan and the central axis of the impeller of the heat dissipation fan are parallel to each other.

[0014] In order to make the airflow blown out by the heat dissipation fan enter the interior of the range fumes exhaust fan more smoothly, the heat dissipation fan is arranged above the range fumes exhaust fan, and the air outlet of the heat dissipation fan faces downward and toward the ventilation port.

[0015] Compared with the prior art, the advantages of the utility model are: the condenser of the heat dissipation module of the refrigeration type range hood is arranged vertically, and the evaporation net is arranged on the side wall of the condenser. When the condenser is arranged tilted due to the installation error of the whole machine, the condensed water falling on the condenser can be absorbed by the evaporation net, thereby prolonging the residence time of the condensed water on the condenser and improving the heat exchange efficiency of the condenser. Moreover, when the condensed water flowing from the condenser accumulates to a certain amount, the switch will be turned on, and the condensed water will enter the volute of the range hood fan to self-clean the range hood fan, thereby realizing the effective utilization of the condensed water.

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the refrigeration type range hood of this embodiment includes a range hood module 1, a compressor 2, a heat dissipation module 3 and an indoor module 4. The range hood module 1 includes a range hood fan 11. The heat dissipation module 3 and the indoor module 4 are arranged outside the range hood fan 11. The heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32. The heat dissipation fan 32 is used to dissipate heat from the condenser 31. The indoor module 4 includes an evaporator 41 and an indoor fan 42. In the cooling mode, the indoor fan 42 blows out cold air. Figure 3 As shown, the compressor 2, the condenser 31 and the evaporator 41 are connected via the refrigerant pipeline 100. The compressor 2, the condenser 31 and the evaporator 41 constitute an air conditioning component, and its working principle can refer to the existing air conditioning principle and will not be described in detail here.

[0024] In this embodiment, both the range hood fan 11 and the heat dissipation fan 32 are centrifugal fans. The heat dissipation fan 32 is arranged above the range hood fan 11, and the central axis of the impeller of the range hood fan 11 is parallel to the central axis of the impeller of the heat dissipation fan 32. The range hood fan 11 includes a volute 111, and a water inlet 112 is opened on the volute 111. The condenser 31 in this embodiment is arranged vertically, and a water receiving box 91 is installed below the evaporator 41. The water receiving box 91 is used to receive the condensed water flowing from the surface of the evaporator 41. A water outlet pipe 92 is connected between the water receiving box 91 and the condenser 31, and a water pump 93 is installed on the water outlet pipe 92. When the water pump 93 is turned on, the condensed water in the water receiving box 91 is transported to the top of the condenser 31 to cool the condenser 31. On the one hand, the heat exchange effect of the condenser 31 is improved, and the air conditioning energy efficiency is improved. On the other hand, the effective treatment of condensed water is also achieved.

[0025] In this embodiment, an evaporation net 5 is attached to the side wall of the condenser 31, and the evaporation net 5 is also arranged vertically. Along the airflow direction, the evaporation net 5 is arranged downstream of the condenser 31, and the heat dissipation fan 32 is arranged downstream of the evaporation net 5, forming an air suction effect. After the evaporation net 5 is arranged, when the air conditioner is turned on at a high gear, the heat dissipation fan 32 is at the maximum gear, and the suction force is large. The condensed water on the condenser 31 will be sucked onto the evaporation net 5, and the condensed water will not be brought out from between the fins of the condenser 31, and the water splashing phenomenon will not be caused.

[0026] like Figures 4 to 6 As shown, the vertical projection of the bottom of the condenser 31 and the vertical projection of the bottom of the evaporation net 5 both fall within the water storage box 6. Figure 6As shown, when the condenser 31 and the evaporation net 5 are tilted relative to the vertical plane due to the installation error of the whole machine, due to the effect of gravity, part of the condensed water falling on the top of the condenser 31 flows downward along the condenser 31, and the other part flows to the evaporation net 5 and flows downward along the evaporation net 5. According to the retention time of the condensed water on the condenser 31, sufficient heat exchange can be achieved. In addition, a water outlet 61 is opened at the bottom of the water storage box 6, and the water outlet 61 is connected to the water inlet 112 through the water outlet channel 7. The unconsumed condensed water flows from the condenser 31 and the evaporation net 5 into the water storage box 6. A gravity sensing switch 8 is installed at the water outlet 61. When the amount of water in the water storage box 6 reaches an appropriate amount, the gravity sensing switch 8 is turned on, and the condensed water in the water storage box 6 flows into the volute 111 of the range hood fan 11 through the water outlet channel 7, so that the range hood fan 11 can be self-cleaned.

[0027] A vent 113 is provided on the volute ring wall of the range fume exhaust fan 11, and the heat dissipation fan 32 is arranged above the range fume exhaust fan 11, and the air outlet of the heat dissipation fan 32 faces downward and toward the vent 113, and the air outlet of the heat dissipation fan 32 can be fluidly connected with the inside of the volute 111 through the vent 113. An air guide valve 10 capable of opening and closing the vent 113 is installed at the vent 113. When the air guide valve 10 is opened, the hot air blown by the heat dissipation fan 32 enters the volute of the range fume exhaust fan 11, and when the air guide valve 10 is closed, the air outlet of the heat dissipation fan 32 is isolated from the volute of the range fume exhaust fan 11. The air guide valve 10 can be in a variety of different forms, and the air guide valve 10 of this embodiment is a rotary valve.

[0028] In this embodiment, along the air flow direction, the vent 113 is arranged upstream of the water inlet 112. During operation, when the condensed water in the water storage box 6 accumulates to a certain amount, the gravity sensor switch 8 is automatically opened, and the high-temperature hot air from the heat dissipation fan 32 blows along the volute ring wall, and the hot air can usually reach about 70°C. At the same time, the condensed water with a temperature increased after heat exchange in the condenser 31 enters the volute, and the temperature of the condensed water can reach about 45°C, thereby performing double combined cleaning of the range fumes fan 11, and the cleaning effect is better.
