Description

Technical Field

[0001] The invention relates to a range hood, in particular to an air outlet passage and an air-conditioning type range hood equipped with the air outlet passage. Background Art

[0002] Various refrigeration range hoods are disclosed in the prior art. On the basis of the range hood platform, an air conditioning module is added. The air conditioning module includes a compressor, a heat dissipation module and an internal unit module. When working in the refrigeration mode, the internal unit module blows out cold air, and the cold air blows toward the cook to enhance the cooking experience. The current integrated kitchen refrigeration range hood generally sets the air outlet on the upper edge of the cabinet door, so that the air outlet is embedded in the cabinet. The air outlet frame needs to be installed separately on the upper edge of the cabinet and cannot be installed together with the range hood. The air outlet is set on the upper edge of the cabinet door, and the air outlet is relatively high. Due to the angle, the user standing in front of the range hood cannot be blown by the cold air or blows on the head, which is less comfortable. In addition, the air outlet is far away from the user, so that the user perceives a higher air outlet temperature, no cool feeling, and poor physical examination. In addition, the existing air outlet generally controls the air outlet direction by swinging the wind up and down on the air guide plate. The width of the air outlet is generally within 500mm, there is no left and right air guide mechanism, the air outlet area is narrow, and the air outlet width is insufficient, which makes it difficult to blow cold air in the left and right directions. Another type of kitchen air-conditioning range hood has an air outlet above the range hood and exhausts air below the cabinet door. The cold air from the internal unit is transferred into the air outlet through a cold air duct from top to bottom and blown out. The cold air duct is too long from top to bottom, resulting in a large loss of cooling capacity. In addition, since the cold air duct will encroach on the air duct space of the range hood, the noise of the range hood will become louder, which will also have an adverse effect on the oil fume extraction effect. Summary of the invention

[0003] The first technical problem to be solved by the present invention is to provide an air outlet passage having a long strip-shaped air outlet that can achieve uniform air outlet in response to the above-mentioned existing technical status.

[0004] The second technical problem to be solved by the present invention is to provide an air-conditioning type range hood with an air-conditioning outlet capable of evenly discharging air in response to the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: the air outlet channel includes a long strip of air outlet frame, and the air outlet frame has an air inlet and an air outlet, and is characterized in that: the air inlet is arranged on the rear side of the air outlet frame and is located at one end of the air outlet frame, the air outlet is arranged on the front side of the air outlet frame and extends along the length direction of the air outlet, and a sinking main air duct, a sinking left air duct and a sinking right air duct are formed inside the air outlet frame, and the sinking left air duct and the sinking right air duct are respectively arranged on the left and right sides of the sinking main air duct, and a ventilation port connected with the air inlet is opened at the rear of the sinking main air duct, and the wind energy entering the sinking main air duct from the ventilation port can be diverted to the two sides to the sinking left air duct and the sinking right air duct.

[0006] Preferably, the downward main air duct, the downward left air duct and the downward right air duct all have a front wall and a rear wall, the upper edge of the front wall constitutes the lower edge of the air outlet, and the upper edge of the rear wall constitutes the upper edge of the air outlet. In this way, after the air enters each downward air duct, it can be blown out from the air outlet smoothly.

[0007] In order to make the air in the left and right downward air ducts more easily overflow, the front walls of the left and right downward air ducts are tilted downward from front to back. This arrangement takes into account the low diversion flow in the left and right downward air ducts, which need to overflow as soon as possible to improve the uniformity of air output.

[0008] Preferably, the inclination angles of the sunken left front wall of the air duct and the sunken right front wall of the air duct are equal.

[0009] Further preferably, the front wall of the sunken main air duct is tilted downward from front to back, and the tilt angle of the front wall of the sunken main air duct relative to the vertical plane is smaller than the tilt angle of the front wall of the sunken left air duct and the front wall of the sunken right air duct relative to the vertical plane. This is because the sunken main air duct is used to receive the main cold air diversion, which requires a larger cross-sectional area to reduce wind resistance. At the same time, because the wind speed here is high, it is easy to overflow.

[0010] Further preferably, the front wall of the sunken main air duct is arranged vertically.

[0011] In order to guide the air overflow direction along the upper wall flow channel, the rear wall of the sunken main air duct, the rear wall of the sunken left air duct and the rear wall of the sunken right air duct are all arranged to be inclined downward from front to back.

[0012] Further preferably, the rear wall of the sunken main air duct, the rear wall of the sunken left air duct and the rear wall of the sunken right air duct all include a rear upper wall and a rear lower wall, and the inclination angle of the rear upper wall relative to the horizontal plane is smaller than the inclination angle of the rear lower wall relative to the horizontal plane.

[0013] In order to improve the uniformity of air outlet, the bottom of the sunken main air duct is lower than the bottom of the sunken left air duct and the sunken right air duct.

[0014] In order to smoothly guide the wind from the air inlet to the other end of the downward main wind channel, the air inlet has a lower wind guide slope and a side wind guide slope for guiding the wind into the downward main wind channel. After the wind is guided by the lower wind guide slope and the side wind guide slope, the airflow can be blown out from the air outlet evenly.

[0015] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the air-conditioning type range hood includes a fan frame and an air inlet body arranged below the fan frame, and a compressor, a heat dissipation module and an indoor unit module are installed on the outside of the fan frame, and the compressor, the heat dissipation module and the indoor unit module are connected through a refrigerant pipeline. The indoor unit module has an indoor unit air inlet and an indoor unit air outlet, and is characterized in that: the air outlet duct is installed on the front of the air inlet body, and the indoor unit air outlet is connected with the air inlet of the air outlet duct through a conversion interface.

[0016] Further preferably, the indoor unit module is arranged on the right side of the fan frame, and the indoor unit air outlet is arranged above the air inlet of the air outlet duct.

[0017] Further preferably, the air outlet of the internal unit is arranged directly above the air inlet of the air outlet channel. In this way, the adapter can be a straight-through channel, and the air intake is smoother.

[0018] Compared with the prior art, the advantages of the present invention are: the air inlet of the air outlet channel is arranged at the rear side of the air outlet frame and at one end of the air outlet frame, the air outlet is arranged at the front side of the air outlet frame and extends along the length direction of the air outlet, and the air outlet frame is formed with a sinking main air duct, a sinking left air duct and a sinking right air duct. The wind entering the air inlet is first blown into the sinking main air duct from top to bottom, and then diverted to the two sides to the sinking left air duct and the sinking right air duct, so that the wind in the sinking air duct will be evenly distributed along the two sides of the air outlet, and under the influence of wind pressure, the wind will overflow upward from the sinking main air duct, the sinking left air duct and the sinking right air duct, and finally blown out evenly at the air outlet. The air-conditioning range hood installs the air outlet channel on the air inlet body, has a short air outlet distance, small air outlet temperature attenuation, obvious low temperature perception, and good user experience.

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the air outlet channel of this embodiment includes a long strip air outlet frame 1, and the air outlet frame 1 has an air inlet 11 and an air outlet 12. The air inlet 11 is arranged at the rear side of the air outlet frame 1 and at one end of the air outlet frame 1, and the air outlet 12 is arranged at the front side of the air outlet frame 1 and extends along the length direction of the air outlet 12. Figure 3 The direction indicated by the middle arrow A is right, and a sinking main air duct 31, a sinking left air duct 32 and a sinking right air duct 33 are formed inside the air outlet frame 1, and the sinking left air duct 32 and the sinking right air duct 33 are respectively arranged on the left and right sides of the sinking main air duct 31. A vent 13 connected to the air inlet 11 is opened at the rear of the sinking main air duct 31, and the wind energy entering the sinking main air duct 31 from the vent 13 is diverted to the sinking left air duct 32 and the sinking right air duct 33 to both sides.

[0031] The sinking main air duct 31, the sinking left air duct 32 and the sinking right air duct 33 all have a front wall and a rear wall. The upper edge of the front wall constitutes the lower edge of the air outlet 12, and the upper edge of the rear wall constitutes the upper edge of the air outlet 12. The sinking left air duct front wall 321 and the sinking right air duct front wall 331 are both arranged to be inclined downward from front to rear. In this embodiment, Figure 4 and Figure 6 As shown, the inclination angles of the sunken left side air duct front wall 321 and the sunken right side air duct front wall 331 are equal, both of which are θ.

[0032] The front wall 311 of the sunken main air duct is tilted downward from front to back, and the tilt angle of the front wall 311 of the sunken main air duct relative to the vertical plane is smaller than the tilt angles of the front wall 321 of the sunken left air duct and the front wall 331 of the sunken right air duct relative to the vertical plane. The function of the sunken main air duct 31 is to receive the main cold air diversion, which requires a larger cross-sectional area to reduce wind resistance. At the same time, because the cold air velocity here is high and easily overflows, it is best for the front wall 311 of the sunken main air duct in this embodiment to be vertically arranged.

[0033] like Figures 4 to 6 As shown, the sinking rear wall 312 of the main air duct, the sinking rear wall 322 of the left air duct, and the sinking rear wall 323 of the right air duct are all arranged obliquely downward from front to back. The sinking rear wall 312 of the main air duct, the sinking rear wall 322 of the left air duct, and the sinking rear wall 323 of the right air duct all include a rear upper wall and a rear lower wall. In this embodiment, the inclination angle of the rear upper wall relative to the horizontal plane is α, and the inclination angle of the rear lower wall relative to the horizontal plane is β, and α<β is satisfied. Angle β causes the cold air to flow upward along the wall surface, and angle α further guides the cold air to flow out along the air outlet 12. The angle affects the guiding effect, and its range is 30°≤β≤80°, 10°≤α≤70°, and the optimal is β=66°, α=44°.

[0034] In this embodiment, the height of the sunken main air duct 31 is a, and the front-to-back width of the bottom of the sunken main air duct 31 is b. The larger the height a of the sunken air duct, the smaller the wind resistance, but the more difficult it is for the cold air to overflow along the right-angle wall. The width b is restricted by space, and the larger its value, the correspondingly smaller the wind resistance. Therefore, the height a ranges from 20mm≤a≤80mm, and the optimal value is 44mm. The width b ranges from 15mm≤b≤60mm, and the optimal value is 34mm.

[0035] For the sunken left side air duct 32, its height c affects the diversion flow and the uniformity of its overflow. If it is too large, the diversion flow is small and the overflow is concentrated on the far right. If it is too small, the diversion flow is large and it is easy to overflow in advance, and the wind speed on the far right is relatively small. Therefore, the height c range is 10mm≤c≤70mm, and the optimal is 23mm, satisfying c<a.

[0036] For the sinking right side air duct 33, the role of setting the inclination angle θ is to make the cold air easier to overflow outwards and avoid rushing straight to the bottom. The larger the value, the easier it is to overflow in advance, and the closer to a right angle, the easier it is to overflow on the leftmost side. Therefore, its range is 95°≤θ≤160°, and its optimal value is 120°. In this embodiment, the bottom of the sinking main air duct 31 is lower than the bottom of the sinking left side air duct 32 and the sinking right side air duct 33, that is, the height of the sinking right side air duct 33 is also less than the height of the sinking main air duct 31. For example, the height of the sinking right side air duct 33 can be designed to be equal to or close to the height of the sinking left side air duct 32.

[0037] In order to smoothly guide the airflow flowing into the air inlet to the left end of the sinking main air duct 31, in this embodiment, the air inlet 11 has a lower air guide slope 111 and a side air guide slope 112 for guiding the air into the sinking main air duct 31. After being guided by the lower air guide slope 111 and the side air guide slope 112, the airflow can flow through the entire sinking main air duct 2. Under the adjustment allowed by the size, the larger the inclination angle of the side air guide slope 112, the better the air guide effect, but if it is too large, it will occupy the oil fume suction cavity, resulting in the oil fume suction effect being affected.

[0038] like Figures 7 to 10 As shown, the air-conditioning range hood of this embodiment includes a fan frame 4, an air inlet body 5 is installed at the lower part of the fan frame 4, a compressor 6, a heat dissipation module 7 and an indoor module 8 are installed outside the fan frame 4, the compressor 6, the heat dissipation module 7 and the indoor module 8 are connected through a refrigerant pipeline, and the indoor module 8 has an indoor air inlet 81 and an indoor air outlet 82. The above structure is the same as that of the existing air-conditioning range hood, and the specific description is not repeated.

[0039] The air outlet channel of this embodiment is installed at the upper part of the front of the air inlet body 5, the air inlet 11 of the air outlet channel is vertically upward, the indoor unit module 8 is installed on the right side of the fan frame 4, the indoor unit air outlet 82 is vertically downward and located directly above the air inlet 11, and the indoor unit air outlet 82 is connected to the air inlet 11 through the adapter 9. When the range hood works in the cooling mode, air enters from the indoor unit air inlet 81, and after heat exchange in the evaporator of the indoor unit module, it enters the adapter 9 through the fan, and finally blows out the cold air through the air outlet 12 of the air outlet channel. The function of the air outlet channel is to allow the cold air entering the air inlet 11 to be blown out evenly in the length direction of the air outlet 12. In addition, the air outlet frame 1 is equipped with wind guide blades, stepper motors and other components, the function of which is to adjust the wind guide plate, guide the wind direction of the cold air, and improve comfort.

[0040] The air outlet duct of this embodiment is installed on the air inlet body 5, with high integration, no need to be fixed to the cabinet, and more convenient installation and maintenance. The air outlet 12 of the air outlet duct is close to the cook, the air outlet distance is short, the air outlet temperature attenuation is small, the cold loss is small, the low temperature perception is obvious, and the left and right widths of the air outlet 12 of the air outlet duct can be designed to be equivalent to the width of the air inlet body 5, thereby covering a wider air outlet range. In addition, the cold air duct of the air-conditioning range hood does not occupy the range hood duct, which is the same as the duct of an ordinary range hood, and the ventilation of the parts is strong.
