Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a range hood assembly and an integrated stove. Background Art

[0002] In the related art, a large amount of water vapor is mixed in the oil smoke inhaled by the integrated stove during operation. This part of water vapor will form condensed water near the fan. If the condensed water enters the fan, it will cause destructive faults such as short circuit, affecting the safety and reliability of the integrated stove.

[0003] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the present invention is to provide a range hood assembly.

[0006] The second aspect of the utility model is to provide an integrated stove.

[0007] In view of this, according to one aspect of the utility model, a range hood assembly is proposed, comprising: a shell; a fan, disposed in the shell; an electrical connection component, connected to the shell, the first end of the electrical connection component is connected to the fan, and the second end of the electrical connection component is used to connect to a circuit board; wherein the fan includes an air inlet side, and the electrical connection component avoids the air inlet side of the fan.

[0008] The range hood assembly provided by the utility model comprises a housing, a fan and an electrical connection component. The fan is located in the housing, and the electrical connection component is connected to the housing to connect to the fan in the housing. The first end and the second end of the electrical connection component are respectively connected to the fan and the circuit board, and the fan can be controlled by the connection of the electrical connection component.

[0009] On this basis, the fan includes an air inlet side, which is the direction of airflow entering the shell. The electrical connection component avoids the air inlet side of the fan, that is, the outlet position of the electrical connection component is far away from the airflow direction of the fan. The reason for the above arrangement is that the oil fume gas inhaled by the fan often contains a large amount of water vapor, and part of the water vapor will enter the shell along the flow channel and condense into water again. At this time, there is a fan in the shell. If the condensed water is not treated, the condensed water may penetrate into the fan, causing destructive failures such as short circuits. Therefore, the present application avoids the air inlet side of the fan by the electrical connection component, forming the electrical connection component facing away from the direction of airflow, to prevent condensed water from entering the fan along the electrical connection component, thereby blocking water vapor from entering the gap between the power cord and the rotor, thereby preventing condensed water vapor from entering the fan to cause power failures and damage the fan, thereby improving product safety, ensuring the operating efficiency of the fan, and increasing the service life of the range hood components.

[0010] In addition, the range hood assembly provided by the present invention may also have the following additional technical features:

[0011] In some technical solutions of the present invention, optionally, the fan is a centrifugal fan, the fan is connected to the bottom wall of the shell, and the air inlet side of the fan faces away from the bottom wall of the shell; the electrical connection component is connected to the bottom wall of the shell.

[0012] In this technical solution, the fan adopts a centrifugal fan. The centrifugal fan is based on the action of centrifugal force. When the fan is started, the internal wind wheel begins to rotate at high speed, and the oil fume gas is sucked in from the air inlet side of the fan, realizing the air intake function.

[0013] One side of the fan is connected to the bottom wall of the shell to achieve fixation between the fan and the shell. The other side opposite to the bottom wall is the air inlet side of the fan, and the electrical connection component is connected to the bottom wall of the shell, so that the electrical connection component is away from the direction of the air inlet side to prevent condensed water from entering the fan along the electrical connection component, thereby preventing water vapor from entering the gap between the power cord and the rotor, thereby preventing condensed water vapor from entering the fan to cause power failure and damage the fan, thereby improving product safety, ensuring the operating efficiency of the fan, and increasing the service life of the range hood components.

[0014] In some technical solutions of the present utility model, optionally, the electrical connection component includes: a cover body connected to the bottom wall of the shell; a wire connected to the cover body, and the wire is used to connect the fan and the circuit board.

[0015] In this technical solution, the electrical connection component includes a cover body and a wire. The cover body is used to connect to the bottom wall of the shell. The wire is arranged on the cover body and is used to connect the fan and the circuit board to realize the control of the operating state of the fan.

[0016] In some technical solutions of the present utility model, optionally, a first gap is left between the cover body and the shell, and the first gap communicates with the inner and outer sides of the shell.

[0017] In this technical solution, there is a first gap between the cover and the shell, the first gap connects the inner and outer sides of the shell, and the water in the shell is discharged to the outside of the shell through the first gap, so as to avoid excessive water accumulation, causing water to enter the fan wire position, causing short circuit and other destructive faults.

[0018] In some technical solutions of the present invention, optionally, the fan includes: a stator connected to the bottom wall of the shell; a rotor connected to the stator, with a second gap left between the stator and the rotor; and a wind wheel connected to the rotor.

[0019] In this technical solution, the fan includes a stator, a rotor and a wind wheel. The stator is arranged on the bottom wall of the housing, and the stator is connected to the rotor, and a second gap is provided between the two for the rotor to rotate freely in the cavity of the stator. The wind wheel is connected to the rotor, and the rotation of the wind wheel is realized through the connection between the two, and the oil smoke is sucked when the wind wheel is running.

[0020] In some technical solutions of the present invention, optionally, the range hood assembly further includes: a retaining rib, which is arranged on the bottom wall of the shell, and the retaining rib surrounds the second gap and the peripheral side of the electrical connection component.

[0021] In this technical solution, a retaining rib is arranged on the bottom wall of the shell, and the retaining rib surrounds the second gap and the peripheral side of the electrical connection component. It can be understood that when the airflow containing condensed water enters the shell, on the one hand, condensed water will be generated on the wind wheel, and the condensed water will be thrown out under the action of the centrifugal force of the wind wheel, thereby flowing to the lower bottom wall surface; in addition, condensed water will also be generated in the expansion section of the shell itself, thereby adhering to the bottom wall; the condensed water of the above two parts will gather on the bottom wall surface, and when the condensed water increases, it will flow to the retaining rib to prevent the condensed water from flowing into the gap between the rotor and the stator, that is, the second gap. Therefore, the retaining rib is arranged around the second gap and the peripheral side of the electrical connection component to prevent the condensed water from flowing into the gap between the rotor and the stator, reduce the possibility of water intrusion into the fan, and thus avoid destructive failures such as short circuits.

[0022] In some technical solutions of the present utility model, optionally, there are multiple blocking ribs, and the multiple blocking ribs are distributed at intervals.

[0023] In this technical solution, there are multiple ribs, and the number of ribs can be four, that is, the ribs include the first rib, the second rib, the third rib and the fourth rib. Among them, the first rib, the second rib, the third rib and the fourth rib are used to further prevent condensed water from entering the gap between the rotor and the stator, increasing the water flow resistance; the second rib also plays a role in positioning the fan; the third rib and the fourth rib are used as support ribs for the fan.

[0024] A plurality of retaining ribs are distributed at intervals, and a multi-layer retaining rib structure is formed by distributing the plurality of retaining ribs at intervals in layers, so as to more effectively prevent condensed water from flowing into the gap between the rotor and the stator.

[0025] In some technical solutions of the present utility model, optionally, among the multiple retaining ribs, at least one retaining rib is connected to the stator.

[0026] In this technical solution, among the multiple retaining ribs, at least one retaining rib is connected to the stator, so that the retaining rib plays a role in assisting the positioning of the fan.

[0027] In some technical solutions of the present invention, optionally, the range hood assembly further includes: a support member connecting the bottom wall of the shell and the fan, and the support member is located between the fan and the bottom wall of the shell.

[0028] In this technical solution, the support member connects the bottom wall of the housing and the fan, and is located between the fan and the bottom wall of the housing. The support member not only fixes the fan, but also raises the position of the fan relative to the bottom wall, making it more difficult for water to flow into the gap, thereby reducing the possibility of condensed water entering the second gap.

[0029] According to another aspect of the utility model, an integrated stove is provided. The integrated stove includes a range hood assembly as in any of the above technical solutions, and a panel, wherein the panel is connected to the shell.

[0030] The integrated stove provided by the utility model includes a range hood assembly of any of the above-mentioned technical solutions, and therefore has all the beneficial effects of the range hood assembly, which will not be described in detail here.

DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0043] Refer to the following Figures 1 to 6 The invention describes a range hood assembly and an integrated stove according to some embodiments of the invention.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of the utility model proposes a range hood assembly 100, comprising: a shell 110; a fan 120, disposed in the shell 110; an electrical connection component 130, connected to the shell 110, wherein the first end of the electrical connection component 130 is connected to the fan 120, and the second end of the electrical connection component 130 is used to connect to a circuit board; wherein the fan 120 includes an air inlet side 1202, and the electrical connection component 130 avoids the air inlet side 1202 of the fan 120.

[0045] The range hood assembly 100 provided by the utility model comprises a housing 110, a fan 120 and an electrical connection component 130. The fan 120 is located in the housing 110, and the electrical connection component 130 is connected to the housing 110 to connect to the fan 120 in the housing 110. The first end and the second end of the electrical connection component 130 are respectively connected to the fan 120 and the circuit board, and the fan 120 can be controlled through the connection of the electrical connection component 130.

[0046] On this basis, the fan 120 includes an air inlet side 1202, which is the flow direction of airflow entering the housing 110. The electrical connection component 130 avoids the air inlet side 1202 of the fan 120, that is, the outlet position of the electrical connection component 130 is away from the flow direction of the fan 120. The reason for the above-mentioned arrangement is that the oil fume gas inhaled by the fan 120 often contains a large amount of water vapor. Part of the water vapor will enter the shell 110 along the flow channel and condense into water again. At this time, there is a fan 120 in the shell 110. If the condensed water is not processed, the condensed water may penetrate into the fan 120, thereby causing destructive failures such as short circuits. Therefore, the present application avoids the air inlet side 1202 of the fan 120 through the electrical connection component 130, so that the electrical connection component 130 is facing away from the direction of the airflow, so as to prevent the condensed water from entering the fan 120 along the electrical connection component 130, thereby blocking the water vapor from entering the gap between the power cord and the rotor 124, thereby preventing the condensed water from entering the fan 120 and causing power failures and damaging the fan 120, thereby improving product safety, ensuring the operating efficiency of the fan 120, and increasing the service life of the range hood assembly 100.

[0047] The fan also includes an air outlet side 1204, and the air outlet side is perpendicular to the plane where the air inlet side is located. The air inlet side inhales the oil smoke of the fan, and discharges it out of the range hood assembly through the air outlet side and into the external environment.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the fan 120 is a centrifugal fan, the fan 120 is connected to the bottom wall 112 of the shell 110, and the air inlet side 1202 of the fan 120 faces away from the bottom wall 112 of the shell 110; the electrical connection component 130 is connected to the bottom wall 112 of the shell 110.

[0049] In this embodiment, the fan 120 is a centrifugal fan. The centrifugal fan is based on the action of centrifugal force. When the fan 120 is started, the internal wind wheel 126 starts to rotate at high speed, and the oil fume gas is sucked in from the air inlet side 1202 of the fan 120, realizing the air intake function.

[0050] One side of the fan 120 is connected to the bottom wall 112 of the housing 110 to achieve fixation between the fan 120 and the housing 110. The other side opposite to the bottom wall 112 is the air inlet side 1202 of the fan 120, and the electrical connection component 130 is connected to the bottom wall 112 of the housing 110, so that the electrical connection component 130 is away from the direction of the air inlet side 1202 to prevent condensed water from entering the fan 120 along the electrical connection component 130, thereby preventing condensed water from entering the gap between the power line and the rotor 124, thereby preventing condensed water from entering the fan 120 to cause power failure and damage the fan 120, thereby improving product safety, ensuring the operating efficiency of the fan 120, and increasing the service life of the range hood assembly 100.

[0051] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments of the present invention, optionally, the electrical connection component 130 includes: a cover body 132 connected to the bottom wall 112 of the housing 110; a wire 134 connected to the cover body 132, and the wire 134 is used to connect the fan 120 and the circuit board.

[0052] In this embodiment, the electrical connection component 130 includes a cover body 132 and a wire 134. The cover body 132 is used to connect to the bottom wall 112 of the shell 110. The wire 134 is arranged on the cover body 132 and is used to connect the fan 120 and the circuit board to realize the control of the operating status of the fan 120.

[0053] Furthermore, the cover body serves to lead the wires out of the shell and form a seal. At the same time, condensed water overflowing from the retaining ribs to the wire position can flow out from the first gap of the cover body, avoiding excessive water accumulation and causing water to enter the wire position of the fan.

[0054] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments of the present invention, optionally, a first gap 1322 is left between the cover 132 and the shell 110 , and the first gap 1322 communicates with the inner and outer sides of the shell 110 .

[0055] In this embodiment, there is a first gap 1322 between the cover body 132 and the shell 110. The first gap 1322 connects the inner and outer sides of the shell 110. The accumulated water in the shell 110 is discharged to the outside of the shell 110 through the first gap 1322, thereby avoiding excessive water accumulation, causing water to enter the wire 134 of the fan 120, and causing destructive faults such as short circuit.

[0056] like Figure 1 , Figure 2 and Figure 5As shown, in some embodiments of the present invention, optionally, the fan 120 includes: a stator 122 connected to the bottom wall 112 of the housing 110; a rotor 124 connected to the stator 122, with a second gap 1206 left between the stator 122 and the rotor 124; and a wind wheel 126 connected to the rotor 124.

[0057] In this embodiment, the fan 120 includes a stator 122, a rotor 124, and a wind wheel 126. The stator 122 is disposed on the bottom wall 112 of the housing 110, and the stator 122 is connected to the rotor 124, with a second gap 1206 therebetween, and the second gap is used for the rotor 124 to rotate freely in the cavity of the stator. The wind wheel 126 is connected to the rotor 124, and the rotation of the wind wheel 126 is realized through the connection between the two, and then the oil smoke is sucked when the wind wheel 126 is running.

[0058] like Figure 1 and Figure 4 As shown, in some embodiments of the present invention, optionally, the range hood assembly 100 further includes: a retaining rib 140 disposed on the bottom wall 112 of the shell 110 , and the retaining rib 140 surrounds the second gap 1206 and the peripheral side of the electrical connection component 130 .

[0059] In this embodiment, retaining ribs 140 are provided on the bottom wall 112 of the shell 110, and the retaining ribs 140 surround the second gap 1206 and the peripheral side of the electrical connection component 130. It can be understood that when the air flow containing condensed water enters the shell 110, on the one hand, condensed water will be generated on the wind wheel 126, and the condensed water will be thrown out under the action of the centrifugal force of the wind wheel 126, thereby flowing to the surface of the lower bottom wall 112; in addition, condensed water will also be generated in the diffuser section of the shell 110 itself, thereby adhering to the bottom wall 112; the condensed water of the above two parts will gather on the surface of the bottom wall 112, and when the condensed water increases, it will flow to the retaining ribs 140 to prevent the condensed water from flowing into the gap between the rotor 124 and the stator 122, that is, the second gap 1206. Therefore, the retaining ribs 140 are arranged around the second gap 1206 and the circumference of the electrical connection component 130 to prevent condensed water from flowing into the gap between the rotor 124 and the stator 122, thereby reducing the possibility of water intrusion into the fan 120 and avoiding destructive failures such as short circuits.

[0060] like Figure 4 As shown, in some embodiments of the present invention, optionally, there are multiple retaining ribs 140, and the multiple retaining ribs 140 are distributed at intervals.

[0061] In this embodiment, the number of the retaining ribs 140 is multiple, and the number of the retaining ribs 140 can be four, that is, the retaining ribs 140 include a first retaining rib 142, a second retaining rib 144, a third retaining rib 146, and a fourth retaining rib 148. Among them, the first retaining rib 142, the second retaining rib 144, the third retaining rib 146, and the fourth retaining rib 148 are used to further prevent condensed water from entering the gap between the rotor 124 and the stator 122, thereby increasing the water flow resistance; the second retaining rib 144 also serves to position the fan; the third retaining rib 146 and the fourth retaining rib 148 are used as support ribs for the fan.

[0062] Furthermore, the plurality of retaining ribs 140 are distributed at intervals. By distributing the plurality of retaining ribs 140 at intervals and in layers to form a multi-layer retaining rib 140 structure, condensed water can be more effectively prevented from flowing into the gap between the rotor 124 and the stator 122 .

[0063] It should be noted that when the air flow containing condensed water enters the shell, on the one hand, condensed water will be generated on the wind wheel, and the condensed water will be thrown out under the action of the centrifugal force of the wind wheel, and thus flow to the wall of the shell; in addition, condensed water will also be generated in the diffuser section of the shell itself, and thus adhere to the wall of the shell; the above two parts of condensed water will gather on the wall of the shell, and when the condensed water increases, it will flow to the first rib, and when there is too much condensed water, it will cross the first rib and flow to the gap between the first rib and the second rib; when the condensed water increases again, it will cross the second rib, flow to the cover body, and then flow out of the range hood assembly from the first gap between the cover body and the shell.

[0064] like Figure 1 As shown, in some embodiments of the present invention, optionally, among the plurality of retaining ribs 140 , at least one retaining rib 140 is connected to the stator 122 .

[0065] In this embodiment, among the plurality of retaining ribs 140 , at least one retaining rib 140 is connected to the stator 122 , so that the retaining rib 140 plays a role in assisting in positioning the fan.

[0066] like Figure 4 As shown, in some embodiments of the present invention, optionally, the range hood assembly 100 further includes: a support member 150 connecting the bottom wall 112 of the shell 110 and the fan 120 , and the support member 150 is located between the fan 120 and the bottom wall 112 of the shell 110 .

[0067] In this embodiment, the support member 150 connects the bottom wall 112 of the housing 110 and the fan 120, and is located between the fan 120 and the bottom wall 112 of the housing 110. The support member 150 not only fixes the fan 120, but also raises the position of the fan 120 relative to the bottom wall 112, making it more difficult for water to flow into the gap, thereby reducing the possibility of condensed water entering the second gap 1206.

[0068] According to another aspect of the utility model, an integrated stove is provided. The integrated stove includes a range hood assembly 100 as in any of the above technical solutions, and a panel, wherein the panel is connected to a shell 110 .

[0069] The integrated stove provided by the utility model includes the range hood assembly 100 of any of the above-mentioned technical solutions, and therefore has all the beneficial effects of the range hood assembly 100, which will not be described in detail here.

[0070] In a specific embodiment, the rotor of the fan is divided into an inner rotor and an outer rotor, the inner rotor is fixed to the housing by a plurality of studs, the outer rotor is fixed to the wind wheel by interference fit or welding, and the radial displacement between the inner rotor and the outer rotor is limited by a bearing, wherein the number of the studs is four.

[0071] The conductors extend from the housing below the wind wheel. To allow the conductors to exit from the side and not fall downward, a cover is provided below the conductors. The cover includes a connector 1324. The connector may be a buckle structure. Specifically, the cover is connected to the housing by a buckle. The housing is a lower volute.

[0072] It should be noted that the present application solves two problems in the range hood assembly in the related art, namely, condensed water enters the fan and causes power failure, thus damaging the fan. On the one hand, condensed water enters the inside of the fan along the wires; on the other hand, condensed water enters the inside of the fan through the second gap between the rotor and the stator. To address the above two problems, electrical connection components are used to avoid the air inlet side of the fan to prevent condensed water from entering the inside of the fan along the wires, and support members and multi-layer rib structures are used to prevent condensed water from flowing into the gap between the rotor and the stator.

[0073] Specifically, when the smoke and stove integrated machine is working, the oil smoke is sucked in through the impeller of the centrifugal fan in the smoke machine device, and the oil smoke is separated through the activated carbon filter and the grease separator during the suction process, so as to achieve the effect of oil smoke treatment, and finally the treated gas is discharged. However, in this process, the inhaled oil smoke gas often contains a large amount of water vapor. Part of the water vapor condenses into water in the activated carbon and grease separator and is received by the water receiving box, and the other part will enter the volute cavity along the flow channel and condense into water again. At this time, there is a fan in the shell, and the water needs to be treated to prevent water from entering the fan, thereby causing destructive faults such as short circuits. In order to solve the problem of condensed water entering the fan along the wire, the electrical connection component is turned away from the air inlet side. Then, when the condensed water on the air inlet side enters the shell, it cannot enter the fan along the wire, but is attached to the wall of the shell. Therefore, the problem of condensed water entering the fan along the wire is effectively solved.

[0074] Furthermore, in order to solve the problem of condensed water entering the fan through the second gap between the rotor and the stator, on the one hand, the fan is connected to the bottom wall of the housing through a support member. While playing a fixing role, the support member raises the height of the fan relative to the bottom wall. When condensed water enters the fan, it can prevent a certain degree of accumulated water from entering the fan, and prevent destructive failures such as short circuits. On the other hand, multiple retaining ribs are designed to be distributed around the support member at intervals. When condensed water wants to enter the second gap between the rotor and the stator, it needs to pass through multiple retaining ribs. The retaining ribs create a certain resistance to the water flow. With multiple retaining ribs, the flow of water can be blocked in multiple ways. Even if the water overflows from the retaining ribs to the cover body, it can flow out from the first gap, thereby avoiding excessive accumulation of water and causing water to enter the fan wire position, so that it can be discharged in time when water accumulates in the fan.

[0075] Therefore, the solution of the utility model effectively reduces the possibility of water intrusion into the fan, avoids destructive failures such as short circuits, and improves the service life and safety of the fan.
