Description

Technical Field

[0001] This utility model relates to a kitchen ventilation and smoke extraction device, and more particularly to an air-conditioning type range hood. Background Technology

[0002] An air-conditioning range hood adds an air conditioning component to a standard range hood platform, combining the functions of both a range hood and an air conditioner. A common example is a patent document with publication number CN111288545A, which discloses an air-conditioning range hood comprising an air conditioning component and a fume extraction component. The air conditioning component includes a first housing, a second housing, and an air outlet device. The fume extraction component includes a fan frame. The first and second housings are isolated from each other and located on the left and right sides of the fan frame, respectively. A first heat exchanger and a second heat exchanger of the air conditioning component are installed inside the first and second housings, respectively. The fan removes heat from the first heat exchanger, and the air after heat exchange in the second heat exchanger is delivered to the kitchen through the air outlet device. However, this structure is relatively complex to assemble, and its air outlet device is close to the smoke inlet chamber. In actual use, the air blown out by the air outlet device disperses some of the fumes, resulting in insufficient fume extraction efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an air-conditioning type range hood that improves the oil fume extraction effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An air-conditioning type range hood for improving the extraction effect of cooking fumes includes a housing and a fume collection hood installed at the bottom of the housing. An inner shell is installed inside the housing, with a fume chamber formed on the inner side of the inner shell and a cooling chamber formed on the outer side of the inner shell. The lower end of the fume chamber is connected to the fume outlet of the fume collection hood, and the upper end discharges the fumes through an exhaust hood. A cooling device is installed in the cooling chamber. The housing is provided with an air conditioning inlet connected to the cooling chamber and an air conditioning outlet connected to the cooling device. The air conditioning outlet is located at the front end near the top edge of the housing.

[0006] The refrigeration device includes a compressor, a condenser, and an evaporator. The evaporator is installed on the top upper side of the inner shell. An air outlet fan and an air guide shroud are installed sequentially on the front end of the evaporator. After assembly, the air outlet of the air guide shroud extends out of the air conditioning outlet.

[0007] The fume chamber is equipped with a cooling fan and a fume extraction fan with opposite air intake directions. The front end face of the inner shell is provided with a cooling air inlet that communicates with the air inlet of the cooling fan. The condenser is installed on the outside of the cooling air inlet.

[0008] The bottom of the inner shell is provided with a downwardly inclined oil guide section corresponding to the position of the heat dissipation fan, and the bottom of the inner shell is provided with an oil fume inlet corresponding to the position of the oil fume extraction fan.

[0009] The smoke collection hood has a longitudinal section and a transverse section located at the upper end of the longitudinal section and extending forward. The longitudinal section and / or the transverse section is provided with a main air intake. Side smoke collection hoods extending forward are provided on both sides of the longitudinal section. The interior of the side smoke collection hoods is connected to the interior of the smoke collection hood. Side air intakes are provided on the inner side of the side smoke collection hoods.

[0010] The side air intake is located near the front edge of the side smoke hood.

[0011] The opening direction of the side air intake is perpendicular to the opening direction of the main air intake.

[0012] The side air intake extends longitudinally and / or is arranged at longitudinal intervals along the inner side of the side smoke hood.

[0013] The front side and left and right sides of the horizontal part have downward protruding windbreaks, and the inner side of the windbreaks is provided with a concave return air duct, which has an air inlet side and an air outlet side.

[0014] The angle formed by the edge tangent on the air outlet side and the transverse portion is an acute angle.

[0015] The beneficial effects of this utility model are as follows: An inner shell is installed inside the housing, dividing the internal space into an oil fume chamber and a cooling chamber. This arrangement, with both chambers located within the housing, improves space utilization and reduces assembly difficulty. Furthermore, the air conditioning outlet is located near the front edge of the top of the housing, away from the main air intake. This prevents the airflow from blowing away some of the oil fumes, reducing leakage and effectively improving the fume extraction efficiency.

[0016] In addition, this utility model has side fume hoods on both sides of the longitudinal part, and side air inlets are provided on the inner side of the side fume hoods. The longitudinal part, the transverse part and the side fume hoods form a semi-enclosed fume extraction space. Most of the fumes are drawn into the box through the main air inlet. While the fumes that diffuse outward from both sides are drawn into the side air inlets, the side air inlets, which are located near the front edge of the side fume hoods, also draw in the external air around the edge of the side fume hoods. The external air will then draw the fumes that diffuse outward from both sides back into the fume extraction space, which can reduce fume leakage and effectively improve the fume extraction effect.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0032] Reference Figures 1 to 11An air-conditioning type range hood for improving the extraction of cooking fumes includes a housing 1 and a fume collection hood 2 installed at the bottom of the housing 1. An inner shell 3 is installed inside the housing 1. A fume chamber is formed on the inner side of the inner shell 3, and a cooling chamber is formed on the outer side of the inner shell 3. The lower end of the fume chamber is connected to the fume outlet of the fume collection hood 2, and the upper end is discharged through an exhaust hood 5. A cooling device is installed inside the cooling chamber. The housing 1 is provided with an air conditioning inlet 11 connected to the cooling chamber and an air conditioning outlet 12 connected to the cooling device. The air conditioning outlet 12 is located at the front end near the top edge of the housing 1. In this invention, the space inside the housing 1 is divided into a fume chamber and a cooling chamber by the inner shell 3, so that both the fume chamber and the cooling chamber are located inside the housing 1. This improves space utilization and reduces assembly difficulty. In addition, the air conditioning vent is located at the front end near the top edge of the cabinet, away from the main air intake, thus preventing the air from blowing away some of the oil fumes, reducing oil fume leakage, and effectively improving the oil fume extraction effect.

[0033] As a further improvement of this utility model, the air conditioning inlet 11 can be arranged in various optional layout schemes on the housing 1. Preferably, in the first embodiment, the air conditioning inlet 11 is located in the upper region of the front face of the housing 1, specifically near the top edge of the air conditioning outlet 12. Figure 1 As shown; in the second embodiment, the air conditioning inlet 11 is disposed along the longitudinal axis of the air conditioning outlet 12 in the extension area of ​​one or both sides of the air conditioning outlet 12, such as... Figure 2 As shown; in the third embodiment, the air conditioning inlet 11 can be arranged on the top surface of the housing 1, as shown. Figure 3 As shown; in the fourth embodiment, the air conditioning inlet 11 is located on the upper edge of the left and right sides or one side of the housing 1, as shown. Figure 4 As shown. In each embodiment, the air conditioner inlet 11 is always kept away from the main air intake of the fume hood 2, thereby avoiding affecting the fume extraction effect of the main air intake.

[0034] As a further improvement of this utility model, the refrigeration device includes a compressor 41, a condenser 42, and an evaporator 43. The evaporator 43 is installed on the top upper side of the inner shell 3. An exhaust fan 61 and an air guide 62 are sequentially installed on the front end face of the evaporator 43. After assembly, the air outlet of the air guide 62 extends out of the air conditioning outlet 12. A cooling fan 31 and a fume extractor 32 with opposite air inlet directions are installed in the fume chamber. The front end face of the inner shell 3 is provided with a cooling air inlet communicating with the air inlet of the cooling fan 31. The condenser 42 is installed outside the cooling air inlet. In this embodiment, the bottom of the inner shell 3 is provided with a downwardly inclined oil guide part 33 corresponding to the position of the cooling fan 31, and the bottom of the inner shell 3 is provided with a fume inlet 34 corresponding to the position of the fume extractor 32, so that the oil fume in the fume chamber flows into the oil collection groove of the fume collection hood 2.

[0035] As a further improvement of this utility model, the smoke hood 2 has a longitudinal portion 21 and a transverse portion 22 located at the upper end of the longitudinal portion 21 and extending forward. The longitudinal portion 21 and / or the transverse portion 22 are provided with a main air intake 23. Side smoke hoods 24 extending forward are provided on both sides of the longitudinal portion 21. The interior of the side smoke hood 24 is connected to the interior of the smoke hood 2. A side air intake 25 is provided on the inner side of the side smoke hood 24. The side air intake 25 is located near the front edge of the side smoke hood 24. In this invention, the longitudinal part 21, the transverse part 22, and the side fume hood 24 form a semi-enclosed fume extraction space. Most of the fumes are drawn into the fume chamber through the main air intake 23. While the fumes that diffuse outward from both sides are drawn into the side air intake 25, the side air intake 25, located near the front edge of the side fume hood 24, also draws in external air from around the edge of the side fume hood 24. This external air then draws the fumes that diffuse outward from both sides back into the fume extraction space, reducing side fume leakage and effectively improving the fume extraction effect.

[0036] As a further improvement of this utility model, the opening direction of the side suction port 25 is perpendicular to the opening direction of the main suction port 23. This allows the side suction port 25 to draw in oil fumes that diffuse outward from both sides, thus improving the fume extraction effect.

[0037] As a further improvement of this utility model, the side air intake vent 25 extends longitudinally and / or is arranged longitudinally at intervals along the inner side of the side smoke collection hood 24. The shape of the side air intake vent 25 can be different, such as elongated, square, conical, circular, or elliptical. For example, the side air intake vent 25 can be a longitudinally extending elongated shape or a longitudinally spaced circular shape. The structure of the side air intake vent 25 can be flexibly set according to needs.

[0038] As a further improvement of this utility model, the front side and left and right side edges of the transverse portion 22 have downwardly protruding windbreak portions 7. The inner side of the windbreak portion 7 is provided with a concave return air duct 71, which has an air inlet side 72 and an air outlet side 73. The angle formed by the edge tangent of the air outlet side 73 and the transverse portion 22 is an acute angle α. In this utility model, the airflow flowing outward from the upper side is guided by the return air duct 71 and will flow back into the fume extraction space. Since the return air duct 71 has an air inlet side 72 and an air outlet side 73, the greater the airflow flowing on the air inlet side 72, the faster the flow velocity leaving the air outlet side 73. At this time, it will also drive the external air around the edge of the air outlet side 73 into the fume extraction space. The drawn-in external air forms a shielding air curtain, which can further reduce fume leakage.
