Description

TECHNICAL FIELD

[0001] The present application relates to a range hood, in particular to an air outlet cover and an air conditioner type range hood provided with the air outlet cover. BACKGROUND

[0002] The kitchen is hot in summer and cold in winter, and there is a demand for cooling and heating. Therefore, people have invented various kitchen air conditioners to cool the air in the kitchen in summer and provide warm air to the kitchen in winter to improve cooking comfort. In order to improve the integration, people have invented air conditioner type range hoods, that is, air conditioner components are added to the range hood platform, which can realize all the functions of the range hood and also realize the function of the air conditioner. The air conditioner type range hood comprises a box body and an air conditioner indoor unit arranged in the box body. An air outlet cover is generally installed on the box body, and the air blown out by the air conditioner indoor unit is blown out through the air outlet cover to provide a comfortable experience for the cook. However, since the air outlet of the air outlet cover is usually long strip-shaped, the existing design cannot guarantee uniform air outlet from the air outlet of the air outlet cover, which affects the user experience. In view of the above, the existing air conditioner type range hood needs to be further improved. SUMMARY

[0003] The first technical problem to be solved by the present application is to provide an air outlet cover with a strip-shaped air outlet capable of uniform air outlet, in view of the above-mentioned prior art status.

[0004] The second technical problem to be solved by the present application is to provide an air conditioner type range hood capable of ensuring uniform air outlet of the air outlet cover after guiding the air outlet of the air conditioner indoor unit, in view of the above-mentioned prior art status.

[0005] The technical scheme adopted by the present application to solve the above-mentioned first technical problem is: the air outlet cover comprises a cover shell, an air inlet and an air outlet are arranged on the cover shell, an air flow channel is formed in the inside of the cover shell and communicates with the air inlet and the air outlet, characterized in that: the air outlet is long strip-shaped, the air inlet is offset to one side of the length direction of the air outlet, and a flow guiding structure is arranged in the air flow channel to enable the air flow flowing into the air inlet to flow out uniformly from the air outlet.

[0006] Preferably, the air inlet is arranged at the left bottom of the cover shell, the air outlet is arranged at the front side of the cover shell, the air inlet is arranged behind the air outlet, and the air outlet is long strip-shaped and distributed left and right.

[0007] In order to guide the air flow from the left side of the air outlet to the right side, the upper part of the left side wall of the cover shell is formed with a wind guiding part recessed to the right side, and the wind guiding part forms the flow guiding structure.

[0008] Further preferably, the bottom of the air guide section is provided with a first air guide plate that is vertically arranged and tilted diagonally to the right from back to front, and the first air guide plate constitutes the airflow guiding structure. In this way, the first air guide plate can guide the airflow to the right side of the air outlet, so that the air outlet can output air evenly from left to right.

[0009] To improve the uniform flow effect in the left and right directions of the air outlet, the air guiding structure also includes an upper air guide plate and a lower air guide plate. The upper air guide plate is located on the upper inner side wall of the air outlet, and the lower air guide plate is located on the lower inner side wall of the air outlet. The upper air guide plate and the lower air guide plate are both vertically arranged and staggered from each other in the left and right directions.

[0010] To further improve the airflow uniformity in the left and right directions of the air outlet, both the upper and lower air guide plates are tilted diagonally to the right from back to front, and the rightward tilt angle of all the air guide plates formed by the upper and lower air guide plates gradually decreases from left to right.

[0011] In order to ensure that the airflow flowing into the air inlet can be smoothly guided to the air outlet, the air inlet is located at the rear and lower part of the air outlet, and the leading edge of the air inlet is connected to the lower edge of the air outlet by a slope extending forward and upward.

[0012] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: the air-conditioning type range hood includes a housing and an indoor air-conditioning unit installed on the housing. The indoor air-conditioning unit has an air inlet and an air outlet. The air outlet of the indoor air-conditioning unit is located at a position slightly to the left of the middle of the top of the housing. An air outlet hood as described in any one of claims 1 to 7 is installed on the top of the housing. The air inlet of the air outlet hood faces downward and is directly opposite the air outlet of the indoor air-conditioning unit. The air outlet of the air outlet hood faces the front side of the housing.

[0013] In order to allow the air outlet of the indoor unit to blow forward from the middle of the range hood, the air outlet of the air hood is located at the center of the top of the housing.

[0014] Preferably, a range hood fan and a compressor are installed inside the housing. A smoke exhaust chamber is formed inside the housing and downstream of the range hood fan. A first heat exchanger is installed in the smoke exhaust chamber. The indoor unit of the air conditioner has a second heat exchanger. The compressor, the first heat exchanger, and the second heat exchanger are connected by a refrigerant pipeline. In this way, the air-conditioning range hood has a compact structure, high integration, and is easy to install.

[0015] In a further preferred embodiment, the indoor unit of the air conditioner includes an indoor unit housing, in which an air outlet fan and a second heat exchanger are installed. Along the air flow direction, the second heat exchanger is located upstream of the air outlet fan, and the air outlet of the air outlet fan constitutes the air outlet of the indoor unit of the air conditioner.

[0016] Further preferably, the exhaust chamber is provided with a first exhaust channel and a second exhaust channel, and a damper is installed in the exhaust chamber to switch the connection between the first exhaust channel and the second exhaust channel and the outlet of the range hood. In this way, the first exhaust channel constitutes a heat dissipation channel, and the second exhaust channel constitutes a direct exhaust channel. In different operating modes, by switching the damper, the fumes are discharged outward through different exhaust channels.

[0017] To prevent oil fume from contaminating the first heat exchanger, the first heat exchanger is located inside the first exhaust duct. An oil fume purification device is also installed inside the first exhaust duct, and the oil fume purification device is located upstream of the first heat exchanger along the direction of oil fume flow.

[0018] In order for the air outlet to blow out cool air, the first heat exchanger is a condenser and the second heat exchanger is an evaporator. In this way, the air-conditioning type range hood operates in cooling mode.

[0019] Further preferably, a smoke collection chamber is provided at the bottom of the housing, and the smoke inlet of the smoke collection chamber is in fluid communication with the smoke exhaust chamber. In this way, under the action of the fume extraction fan, the oil fumes are drawn in through the smoke inlet and discharged outwards through the smoke exhaust channel.

[0020] In order to purify the air entering the indoor unit of the air conditioner, the air inlet of the indoor unit is located at the top of the housing and faces upwards, and a filter is installed at the air inlet of the indoor unit.

[0021] Compared with the prior art, the advantages of the present invention are as follows: the air outlet of the air hood is elongated, the air inlet is offset to one side of the length direction of the air outlet, and a guide structure is provided in the airflow channel inside the hood to allow the airflow flowing in from the air inlet to flow out of the air outlet evenly. The air outlet of the air conditioner indoor unit of the air conditioner range hood is located at the top of the box and slightly to the left of the middle. The air inlet of the air hood faces downward and is directly opposite the air outlet of the air conditioner indoor unit. This allows the air blown out of the indoor unit's air outlet to be deflected to the right when it blows towards the air outlet of the air hood, so that the air hood can evenly discharge air in the left and right directions, thereby improving the user experience.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 3 As shown, the air outlet cover of this embodiment includes a cover 1, on which an air inlet 11 and an air outlet 12 are provided. An airflow channel 13 is formed inside the cover 1, connecting the air inlet 11 and the air outlet 12. Wherein, Figure 1 The direction indicated by the middle arrow A is to the right. The air outlet 12 is located on the front side of the cover 1. The air outlet 12 has a long strip structure distributed in the left and right directions. The air inlet 11 is located at the bottom left side of the cover 1. The air inlet 11 is located at the lower left rear of the air outlet 12. The leading edge of the air inlet 11 is connected to the lower edge of the air outlet 12 by the slope 18 extending forward and upward.

[0030] An airflow channel 13 is provided with a guide structure that allows the airflow entering through the air inlet 11 to flow out evenly through the air outlet 12. In this embodiment, an airflow guide portion 14 that is concave to the right is formed on the upper part of the left side wall of the cover 1, and the airflow guide portion 14 forms a guide structure. A first airflow guide plate 15 that is vertically arranged and tilted to the right from back to front is provided at the bottom of the airflow guide portion 14, and the first airflow guide plate 15 also constitutes a guide structure.

[0031] In addition, the airflow guiding structure of this embodiment also includes an upper air guide plate 16 and a lower air guide plate 17. The upper air guide plate 16 is disposed on the upper inner side wall of the air outlet 12, and the lower air guide plate 17 is disposed on the lower inner side wall of the air outlet 12. Both the upper air guide plate 16 and the lower air guide plate 17 are vertically arranged and staggered from each other in the left-right direction. Furthermore, in order to guide the airflow to the right side of the air outlet 12, both the upper air guide plate 16 and the lower air guide plate 17 are inclined to the right from back to front. Moreover, the rightward inclination angle of the air guide plates formed by the upper air guide plate 16 and the lower air guide plate 17 gradually decreases from left to right, thereby making the airflow blown out of the air outlet 12 more uniform.

[0032] like Figures 4 to 6 As shown, the air-conditioning type range hood of this embodiment includes a housing 2, so as to... Figure 5The direction indicated by arrow B is to the right, and the indoor unit 3 of the air conditioner is installed on the upper left side of the housing 2. The indoor unit 3 has an air inlet and an air outlet. The indoor unit 3 includes an indoor unit housing 31, and an air outlet fan 33 and a second heat exchanger 32 are installed inside the indoor unit housing 31. Along the air flow direction, the second heat exchanger 32 is located upstream of the air outlet fan 33, and the air outlet of the air outlet fan 33 constitutes the air outlet of the indoor unit 3. In this embodiment, the air inlet and air outlet of the indoor unit 3 are both upward and located at the top center slightly to the left of the housing 2. A filter 34 is installed at the air inlet of the indoor unit 3 to purify the air entering the indoor unit 3. An air outlet cover is installed on the top of the housing 2. The air inlet 11 of the air outlet cover faces downward and is directly opposite the air outlet of the indoor unit 3. The air outlet 12 of the air outlet cover faces the front side of the housing 2 and is located at the center left and right of the top of the housing.

[0033] A range hood fan 4 is installed inside the housing 2, located at the lower part of the housing 2. An exhaust chamber 6 is located inside the housing 2, downstream of the range hood fan 4. In this embodiment, the exhaust chamber 6 has a first exhaust channel 61 and a second exhaust channel 62. A damper 9 is installed in the exhaust chamber 6, capable of switching the connection between the first exhaust channel 61 or the second exhaust channel 62 and the outlet of the range hood fan 4. In this embodiment, the first exhaust channel 61 has a first exhaust port 63, and the second exhaust channel 62 has a second exhaust port 64. The first exhaust port 63 and the second exhaust port 64 are independent of each other. Additionally, a smoke collection chamber 100 is located at the bottom of the housing 2, and the smoke inlet 101 of the smoke collection chamber 100 is in fluid communication with the exhaust chamber 6. When the range hood is working, under the action of the range hood fan 4, the oil fumes are drawn in from the smoke inlet 101 and discharged into the smoke exhaust chamber 6, and finally discharged out of the housing 2 through the smoke exhaust chamber 6.

[0034] In this embodiment, a first heat exchanger 7 and an oil fume purification device 10 are installed in the first exhaust duct 61. Along the direction of oil fume flow, the oil fume purification device 10 is located upstream of the first heat exchanger 7. In this way, the oil fume is purified before flowing through the first heat exchanger 7, avoiding oil fume pollution of the first heat exchanger 7, thereby improving its heat exchange effect and extending its service life.

[0035] A compressor 5 is also installed inside the housing 2, located to the left of the range hood 4. The compressor 5, the first heat exchanger 7, and the second heat exchanger 32 are connected via a refrigerant pipe 8. The compressor 5, the first heat exchanger 7, and the second heat exchanger 32 constitute an air conditioning assembly. A throttling device 102 is installed on the refrigerant pipe 8 between the first heat exchanger 7 and the second heat exchanger 32. In this embodiment, the first heat exchanger 7 is a condenser, and the second heat exchanger 32 is an evaporator; that is, the air conditioning-type range hood operates in cooling mode, and its working principle is as follows:

[0036] With both the range hood and air conditioner on, cooking fumes are exhausted through the first exhaust duct 61. The fume airflow passes over the surface of the first heat exchanger 7 (condenser), cooling and dissipating heat, thus lowering the temperature of the refrigerant flowing through the condenser and improving its heat exchange efficiency. Simultaneously, cool air is blown from the air conditioner vents and ultimately through the air outlets 12 of the vent hood into the kitchen, cooling the kitchen and directly blowing air onto the cook's face, enhancing the cooking experience.

[0037] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
