Abstract
Description
Technical Field
[0001] This utility model relates to a range hood, specifically to an air outlet structure and a refrigerated range hood equipped with the air outlet structure. Background Technology
[0002] To lower the ambient temperature in the kitchen and provide a better user experience, more and more cooling-type range hoods are emerging. These range hoods add an air conditioning module to the existing range hood platform. The air conditioning module includes a compressor, a heat dissipation module, and an indoor unit module. When operating in cooling mode, the indoor unit module blows out cool air towards the cook to enhance the cooking experience.
[0003] For example, Chinese utility model patent ZL202322851247.1 (publication number CN221122333U), entitled "A Range Hood," discloses a range hood comprising a housing with a accommodating space and a cooling device disposed within the accommodating space. The housing has a cold air outlet communicating with the accommodating space, and a selectively rotatable adjustment plate that can be used to adjust the opening size of the cold air outlet. However, this adjustment plate, being only one in number, has poor guiding effect on the cold air, resulting in a low cold air output speed, which affects the user's cooling experience. Furthermore, the diffused cold air also affects the range hood's smoke extraction efficiency.
[0004] Therefore, further improvements are needed to the structure of refrigerated range hoods. Utility Model Content
[0005] The first technical problem to be solved by this utility model is to provide an air outlet structure that can adjust the air outlet angle, in view of the above-mentioned existing technology.
[0006] The second technical problem to be solved by this utility model is to provide a cooling range hood with adjustable air outlet angle, in light of the above-mentioned existing technology.
[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the air outlet structure includes:
[0008] The air outlet frame, on which a motor is mounted, is characterized by further comprising:
[0009] The upper guide plate is located on the air outlet side of the air outlet frame;
[0010] A lower guide plate is disposed below the upper guide plate, and an air outlet channel for cold air to flow out is formed between the upper guide plate and the lower guide plate;
[0011] The motor includes a first motor and a second motor spaced apart on the air outlet frame. The first motor is driven to the upper guide plate, and the second motor is driven to the lower guide plate. The upper and lower guide plates can independently swing up and down under the drive of the corresponding motors, thereby adjusting the air outlet angle.
[0012] To increase the airflow velocity at the air outlet, preferably, in the open state, the upper and lower guide plates are arranged at an angle downwards, and the width w of the air outlet channel gradually decreases along the airflow direction. The downward tilt of the upper and lower guide plates guides the cool air to the user's area, while the gradually decreasing distance between them accelerates the airflow, thus better drawing in surrounding airflow.
[0013] To ensure both cooling and fume extraction effectiveness, preferably, the angle α between the upper guide plate and the horizontal plane is 35°–55°, and the angle β between the lower guide plate and the horizontal plane is 10°–20°. When angle α is too large, the cold air is delivered in a near-vertical direction, which disrupts the airflow of the fumes, thus affecting the fume extraction effect. When angle α is too small, the angle between the upper and lower guide plates is too large, resulting in a more diffused cold airflow, further affecting the cooling effect of the range hood. Similarly, when angle β is too large, the cold air is delivered in a near-vertical direction, disrupting the airflow of the fumes, thus affecting the fume extraction effect. When angle β is too small, the airflow velocity is too high due to the small air outlet area, thus affecting the user's cooling experience. The preferred ranges for angles α and β balance both cooling and fume extraction effectiveness.
[0014] Furthermore, the angle α between the upper guide plate and the horizontal plane is 45°, and the angle β between the lower guide plate and the horizontal plane is 16°.
[0015] To save space, preferably, in the closed state, the upper and lower guide plates can be housed inside the air outlet frame and flush with the front side of the air outlet frame. In the non-cooling state, the upper and lower guide plates of the refrigerated range hood can be housed inside the air outlet frame, avoiding the use of installation space due to protruding structures, improving space utilization, and making the structure of the refrigerated range hood simpler and more aesthetically pleasing.
[0016] The solution adopted by this utility model to solve the second technical problem mentioned above is: a refrigerated range hood, characterized in that: it includes an upper housing and an air inlet body located at the bottom of the upper housing, wherein a range hood fan, a compressor, a heat dissipation module and an indoor unit module are installed inside the upper housing, and the compressor, heat dissipation module and indoor unit module are connected through a refrigerant pipeline, characterized in that: the air outlet structure is installed on the front of the upper housing or the front of the air inlet body, and the air inlet of the air outlet frame of the air outlet structure is fluidly connected to the air outlet channel of the indoor unit module.
[0017] For ease of installation, the air outlet structure is embedded in the upper housing or air inlet, and the front side of the air outlet frame of the air outlet structure is flush with the front side of the upper housing or air inlet. This embedded design eliminates the need for the air outlet structure to be fixed to the cabinet, simplifying installation.
[0018] To bring the air outlet closer to the user, it is preferable that the air outlet structure is arranged horizontally at the lower part of the upper housing or the upper part of the air inlet. This arrangement shortens the air outlet distance and reduces the temperature drop of the air outlet. In this case, cool air can be blown towards the user from the air outlet in a horizontal or near-horizontal direction without adversely affecting the fume extraction effect.
[0019] To improve the air outlet coverage, it is preferable that the air outlet structure is positioned centered on the left and right sides of the upper housing or the air inlet. This arrangement provides a wider air outlet coverage, especially when the width of the air outlet is close to the width of the range hood.
[0020] Compared with the prior art, the advantages of this utility model are as follows: the air outlet side of the air outlet frame is provided with an upper guide plate and a lower guide plate, and an air outlet channel for cold air to flow out is formed between the upper guide plate and the lower guide plate. The upper guide plate can swing up and down independently under the drive of the first motor and the lower guide plate can swing down under the drive of the second motor to adjust the air outlet angle, thereby making the matching angle between the upper guide plate and the lower guide plate more diversified and meeting the user's need to freely choose the air supply experience.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] like Figures 1 to 5 As shown, the air outlet structure in this embodiment includes an air outlet frame 1, on which two motors 2 are installed. Each motor 2 includes a first motor 21 and a second motor 22 spaced apart on the air outlet frame 1. An upper guide plate 3 and a lower guide plate 4 are installed on the air outlet side of the air outlet frame 1, with the lower guide plate 4 located below the upper guide plate 3, forming an air outlet channel 5 for cold air to flow out between them. The first motor 21 is driven and connected to the upper guide plate 3, while the second motor 22 is driven and connected to the lower guide plate 4. Under the drive of the first motor 21, the upper guide plate 3 can be independently controlled to swing up and down, and under the drive of the second motor 22, the lower guide plate 4 can be independently controlled to swing up and down. The independent control of the two motors makes the matching angle of the upper guide plate 3 and the lower guide plate 4 more diverse, thereby meeting the needs of different users to freely choose the air outlet angle. The cold air can be guided to the user's head or body.
[0029] refer to Figure 2 When the cooling range hood is turned on, the upper guide plate 3 and the lower guide plate 4 are arranged at an angle downwards. At this time, the cold air can be guided to the area where the user is located. At the same time, along the air outlet direction, the width w of the air outlet channel 5 gradually decreases, that is, the upper guide plate 3 and the lower guide plate 4 are designed with a tapering structure. This structure can accelerate the airflow, thereby better drawing the surrounding airflow to improve the air outlet effect.
[0030] refer to Figure 2The angle α between the upper guide plate 3 and the horizontal plane is 35° to 55°, and the angle β between the lower guide plate 4 and the horizontal plane is 10° to 20°. In this embodiment, the angle α is preferably 45°, which can avoid the airflow organization of the oil fumes being disturbed due to the angle α being too large, thus affecting the oil fume extraction effect, and can also avoid the cold air being too diffused due to the angle α being too small, thus affecting the cooling effect. In this embodiment, the angle β is preferably 16°, which can avoid the airflow organization of the oil fumes being disturbed due to the angle β being too large, thus affecting the oil fume extraction effect, and can also avoid the air outlet area being too small and the air outlet speed being too large due to the angle β being too small, thus affecting the user's cooling experience.
[0031] In addition, refrigerated range hoods in refrigeration mode (see reference) Figure 2 and Figure 5 The upper guide plate 3 and lower guide plate 4 can independently swing up and down for angle adjustment under the drive of their respective motors. In the non-cooling state (refer to...), the refrigerated range hood... Figure 3 and Figure 4 The upper guide plate 3 and the lower guide plate 4 can be stored inside the air outlet frame 1 and are flush with the front side of the air outlet frame 1. This avoids occupying installation space due to the protruding structure, improves space utilization, and makes the structure of the range hood simpler and more beautiful.
[0032] refer to Figure 4 and Figure 5 The refrigerated range hood in this embodiment includes an upper housing 6 and an air inlet 7 located at the bottom of the upper housing 6. The upper housing 6 houses a range hood fan, a compressor, a heat dissipation module, and an indoor unit module. The compressor, heat dissipation module, and indoor unit module are connected via refrigerant piping. This structure is a conventional structure for a refrigerated range hood and will not be described in detail here. An air outlet structure is installed on the front of the upper housing 6. The air inlet of the air outlet frame 1 of this air outlet structure is fluidly connected to the air outlet channel 5 of the indoor unit module. The air outlet structure is embedded in the upper housing 6, and the front side of the air outlet frame 1 is flush with the front side of the upper housing 6 or the air inlet 7, thus eliminating the need for the air outlet structure to be fixed to the cabinet, simplifying installation. In this embodiment, the air outlet structure is arranged horizontally in the center of the upper housing 6. Alternatively, the air outlet structure can be embedded in the upper part of the upper housing 6. Cold air can also be blown towards the user from the air outlet in a horizontal or near-horizontal direction. This installation structure allows the user to adjust the upper guide plate 3 and the lower guide plate 4 to a suitable air outlet direction, resulting in better comfort and a shorter air outlet distance. Furthermore, the width of the air outlet is comparable to the width of the range hood, which can cover a wider air outlet range.
[0033] The working principle of the cooling range hood's air outlet structure in this embodiment is as follows: When the user turns on the cooling function, driven by the first motor 21 and the second motor 22, the upper guide plate 3 rotates outward and forms an angle α with the horizontal plane, and the lower guide plate 4 rotates outward and forms an angle β with the horizontal plane. The user can independently adjust the air outlet angles of the upper guide plate 3 and the lower guide plate 4. The cold air blows along the air outlet channel 5 between the upper guide plate 3 and the lower guide plate 4 towards the user's area. After the user turns off the cooling function, the upper guide plate 3 and the lower guide plate 4 are folded into the air outlet frame 1 and flush with the front side of the air outlet frame 1.
