Description

Technical Field

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

[0002] The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented a range hood with integrated air conditioning function, which can cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort. Of course, the hot summer in the kitchen is the most urgent pain point to be solved. For this reason, people have invented a refrigeration range hood. The condenser of the air conditioning component is integrated in the range hood. The heat dissipation effect of the condenser is not good, which affects the performance of the air conditioner. In addition, during the use of the air conditioning range hood, condensed water will condense on the surface of the evaporator of the air conditioning component. The existing refrigeration range hood usually transports the condensed water to the condenser through a liquid distributor. Although the condensed water can be used to cool the condenser to improve its heat dissipation effect, when the condensed water flows through the surface of the condenser, the unconsumed condensed water will still drip from the condenser, thereby affecting the reliability of the range hood. In addition, the condensed water is in the oil fume channel. After the air conditioner has been working for a long time, the water treatment capacity is greatly reduced. For example, the Chinese utility model patent with patent number 202121615051.7 (authorization announcement number CN215863614U) discloses "A liquid distributor and an air-conditioned range hood using the liquid distributor". The condenser and liquid distributor of the air-conditioned range hood are arranged in the smoke exhaust channel, and the evaporator is arranged in the air outlet channel. The condensed water condensed on the surface of the evaporator flows into the tube body of the liquid distributor and flows from the water outlet of the liquid distributor to the condenser. If the condensed water is discharged by external discharge, it is necessary to rely on the air conditioning drainage pipe outside the kitchen. In addition, in order to dissipate the heat of the condenser, the prior art also discloses a solution of taking away the heat of the condenser through a range hood fan, but due to the high temperature of the condenser, the temperature of the hot air entering the smoke exhaust channel is high, which is not conducive to the effective heat dissipation of the sheet metal parts of the range hood such as the back of the volute, which will adversely affect the working stability of the range hood. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a refrigeration type range hood which can effectively treat air-conditioning condensate water and has good heat dissipation effect in view of the above-mentioned existing technical status.

[0008] In order to smoothly transport the unconsumed condensed water of the condenser to the filter, the condenser is arranged above the filter, and a water receiving tray is provided between the condenser and the filter. The water receiving tray is used to receive the condensed water flowing down from the surface of the condenser. The condensed water in the water receiving tray can be transported to the filter.

[0009] In order to enable the filter to fully absorb condensed water, the filter includes a cylindrical filter body and an upper drip tray arranged on the top of the cylindrical filter body, a circumferential overflow dam is provided in the upper drip tray, the circumferential overflow dam is lower than the outer peripheral wall of the upper drip tray, a water receiving area is formed between the overflow dam and the outer peripheral wall of the upper drip tray, the condensed water in the water receiving tray is transported to the water receiving area, a water outlet area is formed between the overflow dam and the inner peripheral wall of the upper drip tray, the bottom of the water outlet area is provided with drip holes distributed at intervals along the circumferential direction, and the drip holes are arranged above the cylindrical filter body.

[0011] In order to enable the filter screen to evenly absorb condensed water, the drip holes are arranged directly above the cylindrical filter screen body and are evenly distributed along the circumferential intervals of the upper drip tray.

[0014] Further preferably, the inner diameter of the cylindrical filter body is not less than the diameter of the upper air inlet. In this way, the condensed water adsorbed by the cylindrical filter body can be smoothly taken away by the heat dissipation fan.

[0015] As another preferred solution, the heat dissipation fan may also adopt a double air inlet structure, that is, the heat dissipation fan also has a lower air inlet with the air inlet facing downward.

[0020] Compared with the prior art, the advantages of the present invention are that the condenser, filter and heat dissipation fan in the heat dissipation chamber of the refrigeration type range hood are distributed in sequence along the air flow direction, and the air-conditioning condensed water condensed on the surface of the evaporator can flow through the condenser and the filter in sequence, and the condensed water is diverted to the filter. After the filter is soaked, the heat dissipation fan can take away the water on the filter. On the one hand, the condensed water can be effectively treated, and on the other hand, the temperature of the wind blown out by the heat dissipation fan is reduced. If the heat dissipation outlet of the heat dissipation fan is connected to the heat dissipation channel inside the fan frame, the temperature of the sheet metal parts of the range hood that were originally in contact with the hot air can be reduced, the heat dissipation effect is good, and the working reliability of the range hood is thereby improved.

In addition, the heat dissipation cavity 3 can also be arranged on the left side of the fan frame 21.

[0030] The heat dissipation chamber 3 is equipped with a heat dissipation fan 5, a filter 4, a condenser 12 and a compressor 11, wherein the condenser 12, the filter 4 and the heat dissipation fan 5 are sequentially distributed along the air flow direction. The heat dissipation chamber 3 has a heat dissipation air inlet and a heat dissipation air outlet, the heat dissipation air inlet is connected to the outside of the range hood, and the heat dissipation air outlet is connected to the internal space of the fan frame 21 through the ventilation holes (not shown) on the fan frame 21. In this embodiment, the range hood fan 22 is a centrifugal fan with double-sided air inlets, the front air inlet corresponds to the main air inlet channel, and the oil smoke enters through the main air inlet channel, and the rear air inlet corresponds to the heat dissipation channel, and the heat dissipation chamber 3 is connected to the heat dissipation channel. Under the joint action of the heat dissipation fan 5 and the range hood fan 22, the heat of the condenser 12 and the compressor 11 is taken away by the range hood fan 22.

[0031] In this embodiment, the air conditioner indoor unit 7 is installed on the top of the fan frame 21. The air conditioner indoor unit 7 includes an indoor unit fan 71 and an evaporator 13. The air conditioner indoor unit 7 has a condensed water outlet, which is arranged above the condenser 12. The air conditioning condensed water flows out from the condensed water outlet and flows to the surface of the condenser 12. The filter 4 is arranged below the condenser 12, and a water receiving pan 6 is arranged between the condenser 12 and the filter 4. The condensed water that is not consumed by the condenser 12 first flows into the water receiving pan 6, and then flows to the filter 4 through the water outlet pipe 8 at the bottom of the water receiving pan 6.

[0032] like Figure 5 and Figure 6 As shown, the filter screen 4 of this embodiment includes a cylindrical filter screen body 41, an upper drip tray 42 arranged at the top of the cylindrical filter screen body 41, and a lower drip tray 47 arranged at the bottom of the cylindrical filter screen body 41. Specifically, the cylindrical filter screen body 41 is cylindrical, and the upper drip tray 42 and the lower drip tray 47 are both annular. A circumferential overflow dam 43 is arranged in the upper drip tray 42, and the circumferential overflow dam 43 is lower than the outer peripheral wall of the upper drip tray 42. A water receiving area 44 is formed between the overflow dam 43 and the outer peripheral wall of the upper drip tray 42.
