Description

Technical Field

[0001] The present application relates to the technical field of kitchen and bathroom appliances, and in particular to a range hood. Background Art

[0002] A range hood is a common kitchen appliance, which is equipped with a fan. The fan wheel of the fan rotates and extracts the fumes in the kitchen. At present, some people in the market have set a refrigeration mechanism on the range hood to improve the stuffy kitchen environment. However, the existing range hoods with refrigeration and cooling have a simple structure, and the condensed water generated by the refrigeration mechanism is often retained in the corners of the casing and cannot be properly treated, which is easy to breed bacteria and shorten the service life of the range hood. Summary of the invention

[0003] Based on this, it is necessary to provide a range hood that can handle condensed water in a timely manner.

[0004] The present application provides a range hood, comprising: a shell, a range fume blower, an air conditioning component and a drainage component; the shell is provided with a smoke exhaust passage, a smoke inlet and a smoke outlet; the range fume blower, the air conditioning component and the drainage component are all arranged in the shell, the range fume blower is used to draw external air into the smoke exhaust passage through the smoke inlet and discharge it from the smoke outlet; the air conditioning component includes an evaporator, the drainage component has an atomizing nozzle, and the drainage component is used to spray the condensed water generated by the evaporator into the smoke exhaust passage after being atomized by the atomizing nozzle.

[0005] The range hood provided by the present application can realize the cooling function due to the air conditioning component, thereby improving the hot and stuffy environment of the kitchen. In addition, by providing a drainage component, and the drainage component is provided with an atomizing nozzle, the condensed water enters the exhaust channel in the form of water mist, and is discharged to the outside with the flowing air in the exhaust channel, thereby avoiding the condensed water from being retained in the shell or even breeding bacteria, and the water mist is discharged to the outside through the exhaust channel, which can avoid the increase of indoor humidity.

[0006] In one of the embodiments, the air conditioning assembly further includes a condenser, the condenser is connected with heat dissipation fins, and the heat dissipation fins extend into the smoke exhaust passage.

[0007] In this way, the flowing air in the smoke exhaust duct can take away the heat on the condenser in time through the heat dissipation fins, thereby preventing the condenser from releasing heat into the room and causing the indoor temperature to rise. At the same time, timely heat dissipation of the condenser is conducive to extending the service life of the condenser.

[0008] In one embodiment, the smoke outlet is arranged at the top of the shell, the upper part of the smoke exhaust channel is connected to the smoke outlet through the fume fan, the smoke inlet is arranged at the side of the smoke exhaust channel, the atomizing nozzle extends into the smoke exhaust channel and is located above the smoke inlet, and the atomizing nozzle is also located below the heat dissipating fins.

[0009] In this way, the outside air flows upward after entering the exhaust channel from the smoke inlet, passing through the atomizing nozzle and the heat sink fins in turn. The mist condensed water sprayed by the atomizing nozzle flows upward with the flowing air and passes through the heat sink fins. Since the temperature of the condensed water is relatively low, the condensed water plays an additional cooling role on the condenser when passing through the heat sink fins, thereby achieving effective utilization of residual cooling and improving the overall energy efficiency of the range hood. In addition, the air containing water mist is discharged from the smoke outlet to the outside through the range hood fan to avoid an increase in indoor humidity.

[0010] In one of the embodiments, a first partition is provided in the shell, the first partition separates the smoke outlet and the smoke exhaust channel, the fume fan is installed on the side of the first partition away from the smoke exhaust channel, the fume fan is provided with a first air inlet and a first air outlet, the first air outlet is upwardly provided at the top of the fume fan and is connected to the smoke outlet, and the first air inlet is provided on the side wall of the fume fan and is connected to the smoke exhaust channel.

[0011] In this way, under the power of the range fumes fan, the air in the smoke exhaust passage enters the range fumes fan from the first air inlet and is discharged from the first air outlet, and finally the air is discharged to the outside from the smoke outlet.

[0012] In one of the embodiments, the shell is provided with a water collecting plate, which is arranged below the evaporator and is used to receive condensed water generated by the evaporator. The drainage assembly also includes a drainage pump, which is connected to the space above the water collecting plate and the atomizing nozzle through a drainage pipe, so as to allow the condensed water collected on the water collecting plate to be sprayed out through the atomizing nozzle.

[0013] In this way, the condensed water is collected by the water collecting plate, transported by the drainage pump and sprayed from the atomizing nozzle, so that the condensed water generated by the evaporator can enter the smoke exhaust channel in the form of water mist, and then be discharged outdoors with the air flow. The drainage component has a simple structure and can achieve efficient drainage function.

[0014] In one of the embodiments, a water baffle is provided on the water collecting plate, and the water baffle separates the water collecting plate into a water collecting area and a water-free area. The evaporator is installed in the water collecting area, and the drainage pump is installed in the water-free area.

[0015] In this way, the condensed water produced by the evaporator is concentrated in the water collection area, so that the condensed water can accumulate in a small area, so that the condensed water can easily accumulate to a certain height, making it easier for the drain pump to suck the condensed water.

[0016] In one of the embodiments, a water level sensor is provided in the shell corresponding to the water collection area for detecting the water level of the water collection area.

[0017] This embodiment can realize automatic discharge processing of condensed water by providing a water level sensor, thereby improving the automation level of the range hood.

[0018] In one of the embodiments, the side wall of the shell is provided with a second air inlet and a second air outlet, and an air outlet fan is provided on one side of the evaporator. When the air outlet fan is working, external air can enter the shell through the second air inlet, flow through the evaporator and be discharged from the second air outlet.

[0019] In this way, since the evaporator is a heat-absorbing element, the air around the evaporator will become cold, so the outlet fan can be turned on to blow out cold air from the second outlet to cool the room. When the room needs to be cooled, the air conditioning component works and the outlet fan is turned on, and the range hood can blow cold air into the room, thereby cooling the room, greatly improving the user experience of users cooking in the kitchen.

[0020] In one of the embodiments, heat exchange fins are provided at the bottom of the evaporator.

[0021] This helps to improve the heat exchange efficiency between the evaporator and the surrounding air, making the cooling effect better.

[0022] In one of the embodiments, the second air inlet and the second air outlet are arranged on opposite sides of the shell, and the evaporator is arranged close to the second air outlet.

[0023] In this way, the air flows smoothly in the first cavity of the shell, and the second air outlet can blow out cold air more efficiently.

[0024] Compared with the prior art, the range hood provided by the present application can realize the cooling function due to the air conditioning component, thereby improving the hot and stuffy environment of the kitchen. In addition, by providing a drainage component, and the drainage component is provided with an atomizing nozzle, the condensed water enters the smoke exhaust channel in the form of water mist, and is discharged to the outside with the flowing air in the smoke exhaust channel, thereby avoiding the condensed water from being retained in the shell or even breeding bacteria, and the water mist is discharged to the outside through the smoke exhaust channel, which can avoid the increase of indoor humidity.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0036] See also Figures 1 to 4The present application provides a range hood, comprising: a housing 10, a range hood fan 20, an air conditioning component and a drainage component 50, wherein the housing 10 is provided with a smoke exhaust passage 11, a smoke inlet 12 and a smoke outlet 13. The range hood fan 20, the air conditioning component and the drainage component 50 are all arranged in the housing 10. The range hood fan 20 is used to draw external air into the smoke exhaust passage 11 through the smoke inlet 12, and discharge it from the smoke outlet 13. It can be understood that a smoke suction component 141 is provided in the smoke exhaust passage 11, so that when the range hood fan 20 is started, air with smoke enters the smoke exhaust passage 11 from the smoke inlet 12, and the smoke is absorbed by the smoke suction component 141 in the smoke exhaust passage 11, and the air with the smoke absorbed is discharged to the outside (usually discharged to the outside) from the smoke outlet 13, thereby realizing the smoke suction function of the range hood.

[0037] It is understood that the air conditioning assembly includes an evaporator 30, a condenser 40, a compressor and an expansion valve (the compressor and the expansion valve are not shown in the figure), and the working principle of the air conditioning assembly is the same as that of the existing air conditioner, which will not be described in detail here. Among them, the evaporator 30 is a heat absorbing element, which will produce condensed water on the outer wall during operation; the condenser 40 is a heat releasing element, which will release a large amount of heat to the surrounding environment during operation.

[0038] In the present application, the drainage component 50 has an atomizing nozzle 51, and the drainage component 50 is used to spray the condensed water generated by the evaporator 30 into the smoke exhaust channel 11 after being atomized by the atomizing nozzle 51. In this way, the condensed water enters the smoke exhaust channel 11 in the form of water mist, and is discharged to the outside with the flowing air in the smoke exhaust channel 11, thereby preventing the condensed water from being retained in the housing 10 or even breeding bacteria, and the water mist is discharged to the outside through the smoke exhaust channel 11, which can prevent the indoor humidity from increasing.

[0039] Furthermore, the condenser 40 is connected with a heat dissipation fin 41, and the heat dissipation fin 41 extends into the smoke exhaust passage 11. In this way, the flowing air in the smoke exhaust passage 11 can take away the heat on the condenser 40 in time through the heat dissipation fin 41, thereby preventing the condenser 40 from releasing heat into the room and causing the indoor temperature to rise. At the same time, timely heat dissipation of the condenser 40 is conducive to extending the service life of the condenser 40.

[0040] Furthermore, the smoke outlet 13 is arranged at the top of the housing 10, and the upper part of the smoke exhaust channel 11 is connected to the smoke outlet 13 through the oil fume blower 20. The smoke inlet 12 is arranged at the side of the smoke exhaust channel 11, and the atomizing nozzle 51 extends into the smoke exhaust channel 11 and is located above the smoke inlet 12. The atomizing nozzle 51 is also located below the heat dissipation fin 41. In this way, the external air flows upward after entering the smoke exhaust channel 11 from the smoke inlet 12, and passes through the atomizing nozzle 51 and the heat dissipation fin 41 in sequence. The mist condensed water sprayed by the atomizing nozzle 51 flows upward with the flowing air and passes through the heat dissipation fin 41. Since the temperature of the condensed water is relatively low, the condensed water plays an additional cooling role on the condenser 40 when passing through the heat dissipation fin 41, thereby realizing the effective use of the residual cooling and improving the overall energy efficiency of the range hood. In addition, the air containing water mist is discharged to the outside from the smoke outlet 13 through the oil fume blower 20 to avoid the increase of indoor humidity.

[0041] Furthermore, the oil fume suction component 141 is arranged between the smoke inlet 12 and the atomizing nozzle 51, so that the air will reach the atomizing nozzle 51 and the heat dissipation fins 41 only after the oil fume is absorbed, thereby preventing the oil fume from adhering to the atomizing nozzle 51 or even clogging the atomizing nozzle 51, and also preventing the oil fume from adhering to the heat dissipation fins 41.

[0042] In this embodiment, the oil fume suction component 141 is configured as an oil net and is tiltedly disposed in the housing 10 , so that the oil fume carried in the air can be more efficiently absorbed without affecting the normal flow of air.

[0043] An oil collecting box 142 is provided at the lower end of the smoke exhaust channel 11 for collecting the oil smoke absorbed by the oil net.

[0044] See also Figure 3 and Figure 4 Furthermore, a first partition 16 is provided in the housing 10, and the first partition 16 separates the smoke outlet 13 from the smoke exhaust passage 11. The oil fume fan 20 is installed on the side of the first partition 16 away from the smoke exhaust passage 11. The oil fume fan 20 is provided with a first air inlet 21 and a first air outlet 22. The first air outlet 22 is upwardly arranged at the top of the oil fume fan 20 and communicates with the smoke outlet 13. The first air inlet 21 is arranged on the side wall of the oil fume fan and communicates with the smoke exhaust passage 11. In this way, under the power of the oil fume fan 20, the air in the smoke exhaust passage 11 enters the oil fume fan 20 from the first air inlet 21, and is discharged from the first air outlet 22. Finally, the air is discharged to the outside from the smoke outlet 13.

[0045] The oil fume blower 20 is a centrifugal blower with large air volume and good oil fume suction effect. Furthermore, the oil pressure blower is a variable frequency blower. According to the heat generation of the condenser 40, when only the cooling function is performed and the oil fume suction function is not performed, the speed of the oil fume blower 20 can be adjusted to reasonably control the air volume, thereby ensuring the normal operation of the range hood and achieving the effect of energy saving and emission reduction.

[0046] In this embodiment, the fume fan 20, the condenser 40 and the evaporator 30 are arranged on the same side of the exhaust passage 11, the fume fan 20 is arranged above the condenser 40, and the evaporator 30 is arranged below the condenser 40, so that the structure is very compact.

[0047] A support plate 161 is provided at the lower end of the first partition 16, and the condenser 40 is provided on the support plate 161 and is arranged close to the first partition 16. The heat dissipation fins 41 are penetrated through the first partition 16, thereby extending into the smoke exhaust passage 11. In this way, the support plate 161 provides support for the condenser 40 and the first partition 16. In one embodiment, the support plate 161 and the first partition 16 can be provided as an integrally formed structure, so that the support plate 161, the first partition 16, the condenser 40 and the oil fume fan 20 form an integral structure, which is convenient for installation.

[0048] See also Figure 3 and Figure 4 A second partition 17 is further provided in the shell 10 to separate the smoke exhaust channel 11 and the evaporator 30. The second partition 17 is away from the side of the smoke exhaust channel 11 and the shell 10 to form a first cavity 171. The evaporator 30 is installed in the first cavity 171. In this way, the second partition 17 separates the evaporator 30 outside the smoke exhaust channel 11 to prevent the oil smoke in the smoke exhaust channel 11 from contaminating the evaporator 30.

[0049] See also Figure 3 and Figure 4 The housing 10 is provided with a water collecting plate 151, which is provided below the evaporator 30 and is used to receive the condensed water generated by the evaporator 30. The drainage component also includes a drainage pump 52, which is connected to the space above the water collecting plate 151 and the atomizing nozzle 51 through a drainage pipe 53, so as to make the condensed water collected on the water collecting plate 151 be sprayed out through the atomizing nozzle 51. In this way, the condensed water is collected by the water collecting plate 151, and the condensed water is transported by the drainage pump 52 and sprayed out from the atomizing nozzle 51, so that the condensed water generated by the evaporator 30 can enter the smoke exhaust channel 11 in the form of water mist, and then be discharged outdoors along with the airflow. The drainage component 50 has a simple structure and can achieve an efficient drainage function.

[0050] In this embodiment, the water collecting plate 151 is set as the bottom wall of the first cavity 171, and the water collecting plate 151 is set corresponding to the stove. Of course, in other embodiments, the water collecting plate 151 can also be set in the housing 10, and this application does not limit this.

[0051] The drainage assembly 50 is also arranged in the first cavity 171, wherein the atomizing nozzle 51 is penetrated through the second partition 17 and extends into the smoke exhaust channel 11. Of course, the drainage pipe 53 connected to the atomizing nozzle 51 can also be penetrated through the second partition 17, and the atomizing nozzle 51 is fully extended into the smoke exhaust channel 11. The present application does not impose any restrictions on this, as long as the water mist sprayed by the atomizing nozzle 51 can enter the smoke exhaust channel 11.

[0052] Furthermore, a water baffle 152 is provided on the water collecting plate 151, and the water baffle 152 divides the water collecting plate 151 into a water collecting area 1511 and a waterless area 1512. The evaporator 30 is installed in the water collecting area 1511, and the drainage pump 52 is installed in the waterless area 1512. In this way, the condensed water generated by the evaporator 30 is concentrated in the water collecting area 1511, and the condensed water can be accumulated in a small range, so that the condensed water can easily accumulate to a certain height, which is convenient for the drainage pump 52 to suck the condensed water.

[0053] It is understandable that a baffle can be provided at the edge of the water collecting plate 151 to form a water collecting groove, so that a certain height of condensed water can be retained on the water collecting plate 151. However, it is not limited thereto, the water collecting plate 151 can also be sealed and connected to the side wall of the housing 10, so that the water collecting plate 151 and the side wall of the housing 10 enclose a water collecting groove, and a certain height of condensed water can also be retained on the water collecting plate 151, and the present application does not limit this.

[0054] Furthermore, a water level sensor 60 is provided in the housing 10 corresponding to the water collection area 1511, which is used to detect the water level in the water collection area 1511. In this way, the drain pump 52 can be controlled to start and stop according to the height of the water level. Specifically, the range hood is also provided with a controller, which is electrically connected to the water level sensor 60 and the drain pump 52. The controller controls the start and stop of the drain pump 52 according to the water level signal detected by the water level sensor 60. For example, when the water level reaches a preset water level, the drain pump 52 starts to pump water, and when the water level is lower than the preset water level, the drain pump 52 stops. It can be seen that the present embodiment can realize the automatic discharge processing of condensed water by providing the water level sensor 60, thereby improving the automation degree of the range hood.

[0055] See also Figures 1 to 4 The side wall of the housing 10 is provided with a second air inlet 18 and a second air outlet 19, and an air outlet fan 70 is provided on one side of the evaporator 30. When the air outlet fan 70 is working, the external air can enter the housing 10 through the second air inlet 18, and then flow through the evaporator 30 and be discharged from the second air outlet 19. In this way, since the evaporator 30 is a heat absorbing element, the air around the evaporator 30 will become cold, so that the air outlet fan 70 can be turned on to blow out cold air from the second air outlet 19 to cool down the room. When it is necessary to cool down the room, the air conditioning component works and the air outlet fan 70 is turned on, and the range hood can blow cold air into the room, thereby cooling down the room, which greatly improves the user experience of users cooking in the kitchen.

[0056] Furthermore, a heat exchange fin 31 is provided at the bottom of the evaporator 30. This is beneficial to improving the heat exchange efficiency between the evaporator 30 and the surrounding air, so that the cooling effect is better.

[0057] The air outlet fan 70 is installed in the water collecting area 1511 of the water collecting plate 151. Due to the provision of the air outlet fan 70, when a small amount of condensed water remains on the water collecting plate 151 or the heat exchange fins 31, turning on the air outlet fan 70 can also dry the condensed water, thereby preventing the condensed water from breeding bacteria.

[0058] Furthermore, the second air inlet 18 and the second air outlet 19 are disposed on opposite sides of the housing 10, and the evaporator 30 is disposed near the second air outlet 19. In this way, the air flows smoothly in the first cavity 171 of the housing 10, and the second air outlet 19 can blow out cold air more efficiently.

[0059] It is understandable that when the range hood is installed, the back panel of the housing 10 is placed against the wall, the smoke exhaust channel 11 is also close to the wall, and the smoke inlet is arranged on the front panel of the housing 10, corresponding to the stove. The second air inlet 18 and the second air outlet 19 are respectively arranged on the left and right sides of the housing 10, so that the cold air will not face the user or the stove.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
