Description

Technical Field

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

[0002] The current kitchen air conditioner integrates the air conditioner and the range hood into one, but still has an external unit. However, there is often no place to install the external unit outside the kitchen, which is very limited and the installation is limited by space. As an improvement, various refrigeration range hoods are disclosed in the prior art. The refrigeration range hood can realize all the functions of the range hood and the functions of the air conditioner, and the external unit is integrated on the range hood. When working in the cooling mode, the condenser of the air conditioner component will generate heat. Since the condenser is integrated on the range hood, it is necessary to dissipate the heat of the condenser in time, otherwise it will affect the performance of the air conditioner and the service life of the range hood. For example, the Chinese utility model patent No. 202320059220.6 (authorization announcement No. CN 219222570 U) discloses a refrigeration-type range hood, which includes a range hood module, an air conditioner external unit module, and an air conditioner internal unit module. The range hood module includes a fan frame and a range hood fan. The air conditioner external unit module and the air conditioner internal unit module are arranged outside the fan frame. The air conditioner external unit module includes a heat dissipation cavity, a condenser, and a heat dissipation fan. The heat dissipation cavity is arranged outside the fan frame, and the condenser is installed inside the heat dissipation cavity. The heat dissipation fan is located outside the heat dissipation cavity and installed on the top of the heat dissipation cavity. The heat dissipation fan outlet faces the inside of the heat dissipation cavity, and the heat dissipation cavity has a heat dissipation outlet connected to the air inlet of the range hood fan. The heat of the condenser of the refrigeration-type range hood enters the range hood fan through the heat dissipation outlet, and is then taken away by the range hood fan. Although the cooling fan of the range hood is not in the high-temperature hot zone of the external unit module, which is beneficial to increasing the life of the cooling fan and reducing the motor failure rate, and is convenient for repairing and replacing the cooling fan, after the heat of the condenser enters the fan frame, the hot air will transfer the heat to the oil fume air inlet channel. Users are easily burned when maintaining the range hood, and the safety of use needs to be further improved. Utility Model Content

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the refrigeration type range hood of this embodiment includes a range hood module 1, a heat dissipation module 2 and a refrigeration module 3. The range hood module 1 includes a fan frame 11 and a range hood fan 12 installed inside the fan frame 11. The range hood fan 12 is a vertically arranged centrifugal fan. The range hood fan 12 has a front and rear double air inlet structure. The front air inlet side of the range hood fan is an oil liquid air inlet channel 5, and the rear air inlet side of the range hood fan 12 is a heat dissipation channel 4.

[0031] The heat dissipation module 2 in this embodiment is installed on the right side of the fan frame 11. The heat dissipation module 2 includes a compressor 21, a condenser 22 and a heat dissipation fan 23. The heat dissipation fan 23 is arranged below the condenser 22, that is, along the air flow direction, the heat dissipation fan 23 is arranged downstream of the condenser 22. A heat dissipation hole 111 is opened on the right side wall of the fan frame 11, and the air outlet of the heat dissipation fan 23 is connected to the heat dissipation air duct 4 through the heat dissipation hole 111. During operation, high-temperature gas (about 75°C) is generated after the air passes through the heat dissipation module 2, and the heat dissipation fan 23 blows the high-temperature gas into the heat dissipation air duct 4. In addition, the heat dissipation module 2 can also be arranged on the left side of the fan frame 11, and accordingly, the heat dissipation hole 111 is opened on the left side wall of the fan frame 11.

[0032] The refrigeration module 3 of this embodiment is arranged above the fan frame 11. The refrigeration module 3 includes an evaporator 31 and an indoor fan 32. Along the air flow direction, the indoor fan 32 is arranged downstream of the evaporator 31.

The compressor 21, the condenser 22 and the evaporator 31 constitute an air conditioning component, and its working principle can refer to the working principle of the existing air conditioner, which will not be described in detail here.

[0033] In this embodiment, the heat dissipation duct 4 is connected to the air outlet of the heat dissipation module 2, and the oil fume air inlet duct 5 is connected to the smoke inlet of the range hood. The heat dissipation duct 4 and the oil fume air inlet duct 5 are separated by a heat insulation structure 6. The heat insulation structure 6 includes an outer heat insulation board 61, an inner heat insulation board 62, and a heat preservation and heat insulation layer 63 arranged between the outer heat insulation board and the inner heat insulation board. The heat preservation and heat insulation layer 63 is an air interlayer or a heat preservation material interlayer. The heat preservation material can be made of traditional heat insulation materials such as glass fiber and asbestos, or new heat insulation materials such as aerogel felt, vacuum board, and rigid polyurethane. According to experiments, before the double-layer heat insulation scheme is adopted, the surface temperature of the outer heat insulation board 61 is about 55°C. After the double-layer heat insulation structure is adopted, the surface temperature of the outer heat insulation board 61 is about 39°C, which will not burn the user.

[0034] After the heat insulation structure 6 is adopted between the heat dissipation channel 4 and the oil fume air inlet channel 5, the heat in the heat dissipation channel 4 will not be transferred to the oil fume air inlet channel 5. The oil fume and the hot air in the heat dissipation channel 4 converge inside the oil fume suction fan 12 and are discharged to the flue together, thereby avoiding burns to users when maintaining the range hood and improving user safety.

[0035] In addition, an air inlet 13 is provided below the fan frame 11 of the present embodiment, and the air outlet module 7 is provided at the front side of the air inlet 13 and in the middle of the left and right sides.

The air outlet module 7 is embedded in the air inlet 13 and the front side surface is flush with the front side surface of the air inlet 13. When the air outlet is closed, the structure is simpler and the integrity is better. The air outlet of the indoor fan 32 extends forward from the fan frame 11 and faces vertically downward. The air outlet of the indoor fan 32 is connected to the air inlet of the air outlet module 7 through the air duct 8. The air duct 8 is arranged parallel to the front side surface of the fan frame 11, and the air inlet of the air duct 8 is installed at the air outlet of the indoor fan 32. In addition, the space on the left and right sides of the air outlet module 6 is fully utilized, and the display module 10, the control module, etc. can be installed.

In this embodiment, the swing angle of the air guide blade 75 is -60° to 60°, that is, the air can be discharged to the left or to the right. The swing angle of the air guide plate 73 is 0° to 90°. When the air guide plate 73 swings to a horizontal position, the air guide plate 73 is opened, and the air outlet of the air outlet frame 71 discharges air in a horizontal direction. When the air guide plate 73 swings to the vertical position, the air guide plate 73 is closed, that is, the air outlet of the air outlet frame 71 is closed. When the air guide plate 73 is closed, the outer surface of the air guide plate 73 is flush with the front side of the air outlet frame 71. After the air outlet module 7 adopts the above structure, different air outlet angles and air volume distribution are achieved through four-way swinging and air guiding. The user can adjust the appropriate air outlet direction for better comfort.
