Abstract
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 solve the pain point of the kitchen being stuffy during cooking in summer, people invented a refrigeration range hood, which integrates the refrigeration module into the range hood, and sets an air-conditioning outlet on the range hood housing. When working in the refrigeration mode, cold air is blown out through the air-conditioning outlet to improve the user's cooking experience. For example, the Chinese invention patent No. 201710633450.8 (authorization announcement No. CN 108061323 B) discloses a "kitchen fresh air refrigeration machine", in which a fresh air inlet connected to the outside and a fresh air outlet connected to the indoor are provided on the housing, a fresh air channel connecting the fresh air inlet and the fresh air outlet is provided inside the housing, and the fresh air channel and the range hood duct are not connected to each other. A refrigeration device capable of cooling the fresh air blown out from the fresh air outlet is provided in the housing, and when working, the outdoor fresh air enters the refrigeration component after being purified, and flows into the indoor room from the fresh air outlet after being refrigerated. The fresh air outlet of the fresh air refrigeration machine is at a high position and cannot be blown at close range to the cook, resulting in a poor user experience. As an improvement, the current refrigeration-type range hood also has a scheme for sampling the middle air outlet. Since the air outlet position is lowered, the cold air can blow at close range to the human body, which will greatly improve the human body's comfort. However, since the cold air outlet blows out from the middle part of the range hood, it will disrupt the flow field at the inlet of the range hood, thereby reducing the range hood's ability to absorb oil smoke, and thus posing a risk of smoke leakage. As for the structure of the cold air middle air outlet, once smoke leakage occurs, the escaped oil smoke will be directly taken away by the cold air outlet and blown towards the face of the person, resulting in a reduced user experience.

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] like Figure 1 and Figure 2 As shown, the refrigeration 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 an upper box body 11 and a lower box body 12. A range hood fan is installed inside the upper box body 11, and a smoke inlet 120 is provided on the lower box body 12. The heat dissipation module 3 and the indoor module 4 are both arranged outside the upper box body 11, and an air outlet hood 5 is installed on the top of the upper box body 11. The heat dissipation module 3 is arranged above the upper box body 11 and on the right side of the air outlet hood 5. In this embodiment, the indoor module 4 is arranged on the right side of the upper box body 11, and the indoor fan 42 is arranged below the evaporator 41. In addition, along the air flow direction, the indoor fan 42 is arranged downstream of the evaporator 41, and the air outlet of the indoor fan 42 faces downward.
[0020] like Figure 3 As shown, the heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32, and the indoor module 4 includes an evaporator 41 and an indoor fan 42. The compressor 2, the condenser 31 and the evaporator 41 are connected through a refrigerant pipeline 6, and the refrigeration principle is the same as that of the existing air conditioner, which will not be described in detail here.
[0021] In this embodiment, a first air outlet 121 and a second air outlet 122 are opened on the lower box body 12, and the air outlet of the indoor fan 42 faces downward and is fluidly connected with the first air outlet 121 and the second air outlet 122 through a three-way adapter, that is, the cold air can be blown out from the first air outlet 121 and the second air outlet 122 after diversion.
[0022] The first air outlet 121 is provided at the front of the lower box 12 and the air outlet direction is toward the front side. The plane where the first air outlet 121 is located is a vertical plane. A first air guide plate capable of adjusting the air outlet direction is installed at the first air outlet 121. The second air outlet 122 is provided at the bottom of the front side of the lower box 12 and the air outlet direction is toward the front and lower side. A second air guide plate capable of adjusting the air outlet direction is installed at the second air outlet 122.
[0023] The second air outlet 122 is arranged at the lower rear of the first air outlet 121, and the smoke inlet 120 is arranged at the lower rear of the second air outlet 122. The planes where the second air outlet 122 and the smoke inlet 120 are located are both inclined planes that are inclined downward from front to back, and an air guide plate 123 for opening and closing the smoke inlet 120 is installed between the second air outlet 122 and the smoke inlet 120. When the air guide plate 123 is opened, the air guide plate 123 is extended forward and downward, and the projection of the second air outlet 122 in the vertical direction falls on the air guide plate 123.

[0025] When working in the cooling mode, the cold air blown by the indoor fan is blown out through the first air outlet 121 and the second air outlet 122. The cold air blown out of the first air outlet 121 can be blown out of the cook at a close distance to improve the user experience. The cold air blown out of the second air outlet 122 can form a wind curtain between the oil smoke airflow flowing to the smoke inlet and the cold air airflow blown out of the second air outlet 122 to prevent the overflowing oil smoke from blowing toward the user's head. The smoke will not affect the user, greatly improving the experience. In addition, the cold air blown out of the first air outlet 121 and the second air outlet 122 can be adjusted at will through the corresponding air guide plates to meet user needs.
