Description
Technical Field
[0001] The invention relates to a range hood, in particular to an air guide structure and an air-conditioning type range hood equipped with the air guide structure. 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 guide structure for controlling the overflow amount in the downward air duct so that the air outlet can discharge air evenly 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 guide structure 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, a downward air duct is formed inside the air outlet frame, the air inlet is connected with the air outlet through the downward air duct, and an air guide strip is installed at the air outlet, and the air guide strips are arranged at intervals along the length direction of the air outlet.
[0006] In order to make the air outlet more uniform, the distance between adjacent air guide strips gradually decreases along the air outlet direction.
[0007] In order to enable the air guide strip to control the overflow amount in the downward air duct, the air guide strip has a front side facing the air outlet side and a lower side facing the downward air duct. The lower side is arranged above the downward air duct, and at least a part of the lower side is inclined relative to the horizontal plane.
[0008] Further preferably, the lower side of the air guide strip is a straight side, and along the air outlet direction, the inclination angle of the lower side of the air guide strip relative to the horizontal plane gradually decreases. The smaller the inclination angle of the air guide strip relative to the horizontal plane, the greater the corresponding wind resistance, and the easier it is for the cold air in the downward air duct to overflow outward. Therefore, it is necessary to match air guide strips with different inclination angles at different air outlets, so that the overflow amount at each position in the length direction of the air outlet is relatively uniform.
[0009] Further preferably, the front side edge of the air guide strip is a straight edge and is arranged vertically.
[0010] Further preferably, the sinking air duct includes a sinking main air duct, a sinking left air duct and a sinking right air duct, 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 vent connected to 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 vent is diverted to the two sides to the sinking left air duct and the sinking right air duct. With such an arrangement, the wind entering the air inlet will be evenly distributed along the two sides of the air outlet in the sinking air duct, and under the influence of wind pressure, it will overflow upward in 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.
[0011] Further preferably, the downward-sunk main air duct and the downward-sunk right-side air duct are separated by the air guide strip.
[0012] Further preferably, the lengths of the downward main air duct and the downward left air duct are equal, and the number of air guide strips above the downward main air duct is less than the number of air guide strips above the downward left air duct. In this way, the air guide strips corresponding to the downward left air duct downstream of the downward main air duct are densely distributed, which can make the air volume distribution more uniform.
[0013] Further preferably, the air guide strip and the air outlet frame are separate parts.
[0014] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is that 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 by 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 guide structure is installed on the front side of the air inlet body, and the indoor unit air outlet is connected to the air inlet of the air guide structure through a conversion interface.
[0015] 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 guide structure.
[0016] Further preferably, the air outlet of the internal unit is arranged directly above the air inlet of the air guide structure. In this way, the adapter can be a straight-through channel, and the air intake is smoother.
[0017] Compared with the prior art, the advantages of the present invention are: the air inlet of the air guide structure is arranged on the rear side of the air outlet frame and 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, a downward air duct is formed inside the air outlet frame, and by arranging air guide strips at intervals in the length direction of the air outlet, the wind energy entering the downward air duct from the air inlet can be more evenly discharged from the air outlet through the air guide strips, so that the air volume is evenly distributed. The air-conditioning type range hood installs the air guide structure on the air inlet body, the air outlet distance is short, the outlet air temperature attenuation is small, the low temperature perception is obvious, and the user experience is good.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.
[0026] like Figures 1 to 5 As shown, the air guide structure of this embodiment includes a long strip air outlet frame 1, the air outlet frame 1 has an air inlet 11 and an air outlet 12, 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 frame 1, and a downward air duct 3 is formed inside the air outlet frame 1. Figure 2 The direction indicated by the middle arrow A is right, the downward air duct 3 is arranged at the rear and lower part of the air outlet 12, the air inlet 11 is arranged at the rear side of the air outlet frame 1 and at the right end of the air outlet frame 1, and the air inlet 11 is connected with the air outlet 12 through the downward air duct 3.
[0027] The sinking air duct 3 of this embodiment includes a sinking main air duct 31, a sinking left air duct 32 and a sinking right air duct 33. 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 ventilation hole 13 connected to the air inlet 11 is opened at the rear part of the sinking main air duct 31. The wind entering the sinking main air duct from the ventilation hole 13 is diverted to the sinking left air duct 32 and the sinking right air duct 33 on both sides.
[0028] In this embodiment, an air guide strip 2 is installed at the air outlet 12, and the air guide strip 2 and the air outlet frame 1 are separate parts. The air guide strips 2 are arranged at intervals along the length direction of the air outlet 12, and the spacing between adjacent air guide strips 2 gradually decreases along the air outlet direction. The lengths of the sinking main air duct 31 and the sinking left air duct 32 are comparable, and the number of air guide strips 2 above the sinking main air duct 31 is less than the number of air guide strips 2 above the sinking left air duct 32. The sinking main air duct 31 and the sinking right air duct 33 are separated by the air guide strip 2. The spacing between two adjacent air guide strips 2 is d, and the design basis is the diversion situation at the air outlet 12, and the overflow in the sinking air duct 3 is combined to match different numbers of air guide strips 2. In this embodiment, since the cold air overflow in the sinking main air duct 31 has met the demand, only one air guide strip 2 is designed to match the diversion. In the sinking left air duct 32, since the cold air overflows less and easily rushes to the bottom, more air guide strips 2 are matched, and the spacing d is within the range of 30mm≤d≤150mm. When the left side lacks an air guide strip 2, the cold air in the sinking left air duct 32 overflows after being blown to the bottom, resulting in uneven air volume distribution.
[0029] The function of the air guide strip 2 is to allow the cold air to overflow at a suitable position when it circulates in the downward air duct 3. Different angles of the air guide strip 2 will result in different air outlet effects. Different downward air ducts 3 need to match different air guide strips 2, and their angles and spacings are different. The air guide strip 2 of this embodiment has a front side 21 facing the air outlet 12 and a lower side 22 facing the downward air duct 3. The front side 21 is a straight side and is vertically arranged. The lower side 22 is arranged above the downward air duct 3. The lower side 22 of the air guide strip 2 is a straight side. Along the air outlet direction, the inclination angle of the lower side 22 of the air guide strip 2 relative to the horizontal plane gradually decreases, that is, the inclination angle η of the air guide strip 2 should gradually decrease as the cold air overflows. The closer to the left side facing the air outlet 12, the angle should be gradually reduced, so that the cold air gradually overflows outward. In this embodiment, the initial inclination angle η is 60°, and the angle decreases to the left, which is 45° and 30° respectively. The range of η in the present invention is 5°≤η≤85°. The smaller the angle η is, the greater the corresponding wind resistance is, and the easier it is for the cold air in the downward air duct 3 to overflow outward. Therefore, it is necessary to match air guide strips 2 of different angles at different air outlets to achieve a relatively uniform overflow of cold air here.
[0030] When the wind guiding structure guides the wind, after the wind enters from the air inlet 11, it is first blown into the downward air duct 3 from top to bottom. The wind will be evenly distributed along the left and right sides of the air outlet 12 in the downward air duct 3. Under the influence of wind pressure, the wind overflows upward in the downward air duct 3 and is finally blown out evenly at the air outlet 12.
[0031] like Figure 6 and Figure 7 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.
[0032] The air guide structure of this embodiment is installed on the upper part of the front of the air inlet body 5, the air inlet 11 of the air guide structure 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 guide structure. The function of the air guide structure 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 air guide blades, motors and other components, the function of which is to adjust the air guide plate, guide the wind direction of the cold air, and improve comfort.
[0033] The air guide structure 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 guide structure is closer to the cook, the air outlet distance is short, the air outlet temperature attenuation is small, the cooling loss is small, and the low temperature perception is obvious. The width of the air outlet 12 of the air guide structure in the left and right directions can be designed to be equivalent to the width of the air inlet body 5, thereby covering a wider air outlet range.
