Description

Technical Field

[0001] The invention belongs to the technical field of range hoods, and in particular relates to a nozzle, a cleaning system and a range hood. Background Art

[0002] At present, the range hoods on the market mainly pursue two aspects of performance, one is "high performance" and the other is "easy to maintain". As a sewage exhaust appliance, the impeller of the range hood will be sticky with a lot of oil and dirt after inhaling oil smoke after long-term use, which is easy to breed bacteria, reduce air volume performance, increase noise, and produce odor. In response to this problem, there are currently a variety of solutions. One is to provide manual disassembly and cleaning, which is time-consuming and labor-intensive, and has high maintenance costs; the other is the range hood that now has its own cleaning program. The automatic cleaning function of the range hood in the related technology all sprays water or high-temperature steam through the nozzle on the water outlet pipe. The nozzle is fixed in the casing of the range hood, especially in the impeller, to clean the inside of the range hood, especially the impeller.

[0003] However, fixing the nozzle in the body of the range hood, especially on the fixed impeller, limits the cleaning range and only the blade part of the impeller can be cleaned, while the upper and lower edges of the blades and the hub position cannot be rinsed. It is difficult to clean the impeller thoroughly only by the method of melting the oil with high-temperature steam, which may cause the generation of odor, the breeding of bacteria, the reduction of the suction power of the range hood, the increase of noise and other problems, which seriously affect the user experience. Summary of the invention

[0004] In order to solve the problem that the current nozzle cannot completely clean the impeller of the range hood, the present invention provides a nozzle.

[0005] Another object of the present invention is to provide a cleaning system and a range hood using the cleaning system.

[0006] The present invention is achieved by adopting the following scheme:

[0007] The present invention provides a nozzle, which is installed on a tool to be cleaned, and includes a nozzle assembly, a nozzle fixing assembly, a mounting seat and an elastic connection assembly;

[0008] The mounting seat is installed on the tooling; the mounting seat is connected to the nozzle fixing assembly via the elastic connecting assembly; the nozzle assembly is installed on the nozzle fixing assembly, and the nozzle assembly sprays water mist toward the part to be cleaned of the tooling to generate a reaction force, and the reaction force causes the nozzle fixing assembly to drive the nozzle assembly to swing relative to the mounting seat, and at the same time causes the elastic connecting assembly to generate elastic deformation to limit the swing amplitude of the nozzle fixing assembly.

[0009] A further improvement to the nozzle of the present invention is that the nozzle fixing assembly is arranged above the mounting seat; the nozzle assembly sprays water mist toward the area to be cleaned located below the mounting seat to generate a reaction force, and the reaction force causes the nozzle fixing assembly to drive the nozzle assembly to swing up and down relative to the mounting seat, and at the same time causes the elastic connection assembly to produce elastic deformation to limit the swing amplitude of the nozzle fixing assembly up and down.

[0010] A further improvement to the nozzle of the present invention is that the nozzle fixing assembly includes a first fixing member and a second fixing member; the end of the first fixing member is connected to the second fixing member to form a first angle; the nozzle assembly is also mounted on the first fixing member; and the second fixing member is connected to the mounting seat via the elastic connection assembly.

[0011] A further improvement to the nozzle of the present invention is that a first connecting plate is further provided on the nozzle fixing assembly; an end of the first connecting plate is arranged toward the mounting seat, and the first connecting plate is connected to the mounting seat via the elastic connecting assembly.

[0012] A further improvement to the nozzle of the present invention is that the first connecting plate is arranged at the connection between the first fixing member and the second fixing member.

[0013] A further improvement to the nozzle of the present invention is that the nozzle also includes a limit assembly; the limit assembly is installed between the nozzle fixing assembly and the mounting seat to limit the up and down swing amplitude of the nozzle fixing assembly relative to the mounting seat.

[0014] A further improvement to the nozzle of the present invention is that the limit assembly comprises an upper limit member and a lower limit member; the upper limit member is connected to the lower limit member in an upper and lower limit sliding fit.

[0015] A further improvement to the nozzle of the present invention is that the elastic connection assembly includes a first elastic member; the mounting seat includes a mounting plate and a second connecting plate; the second connecting plate is connected to the mounting plate; the mounting plate is installed on a tooling; and the second connecting plate is connected to the first connecting plate via the first elastic member.

[0016] A further improvement to the nozzle of the present invention is that the first elastic member includes a first elastic part and a second elastic part; one end of the first elastic part is connected to one end of the second elastic part to form a second angle; the first connecting plate is inserted into the first elastic part along the axial direction of the first elastic part; and the second connecting plate is inserted into the second elastic part along the axial direction of the second elastic part.

[0017] A further improvement to the nozzle of the present invention is that the elastic connection assembly also includes a second elastic member; the end of the nozzle fixing assembly away from the nozzle assembly is connected to the second elastic member; and the end of the mounting seat away from the nozzle assembly is also connected to the second elastic member.

[0018] A further improvement to the nozzle of the present invention is that the nozzle assembly includes a nozzle and a nozzle pipe; the nozzle pipe is installed on the nozzle fixing assembly; the nozzle is installed at the water outlet of the nozzle pipe; and the water inlet of the nozzle pipe is connected to a water source.

[0019] The present invention also provides a cleaning system, comprising the above-mentioned nozzle, a water cup and a water pumping member; the water pumping member is arranged in the water flow path between the water cup and the nozzle, and is used to pump water from the water cup to the nozzle.

[0020] A further improvement to the cleaning system of the present invention is that the cleaning system also includes a heating element having a heating chamber; the heating element is arranged in the water flow path between the pumping element and the nozzle, and is used to generate high-temperature steam and transport the high-temperature steam to the nozzle.

[0021] The present invention further provides a range hood, comprising the above-mentioned cleaning system and a range hood body; the cleaning system is installed on the range hood body and is electrically connected to a controller of the range hood body.

[0022] Compared with the prior art, the beneficial effects of the present invention using the above scheme are:

[0023] When the nozzle of the present invention is used to clean the tooling to be cleaned, the nozzle assembly sprays water mist toward the part to be cleaned of the tooling, and the impact force of the water mist and the tooling produce a reaction force; because the nozzle fixing assembly on which the nozzle assembly is installed is connected to the mounting seat through an elastic connection assembly, that is, the nozzle fixing assembly has a certain degree of freedom, the reaction force will cause the nozzle fixing assembly to drive the nozzle assembly to swing relative to the mounting seat, and at the same time, the elastic connection assembly will be elastically deformed; the elastic connection assembly that undergoes elastic deformation has a reaction force on the nozzle fixing assembly with a larger swing amplitude, so as to prevent the nozzle assembly from swinging beyond the range of the swing amplitude, and play a role in limiting the nozzle fixing assembly, so that the nozzle assembly can achieve cleaning of the part to be cleaned within a relatively suitable range. Compared with the nozzle with a fixed arrangement of the current nozzle assembly, this embodiment expands the cleaning range without additionally setting a driving member. If the nozzle of this embodiment is installed on the impeller of the range hood, it can effectively solve the problem that the current nozzle cannot fully clean the impeller of the range hood, and improve the suction and cleaning degree.

[0024] Because the cleaning system and range hood of the present invention adopt the above-mentioned nozzle, they can at least effectively solve the problem that the current nozzle cannot completely clean the impeller of the range hood, thereby improving the cleaning degree.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a nozzle, which is installed on the tooling to be cleaned, and includes a nozzle assembly 11, a nozzle fixing assembly 12, a mounting seat 13 and an elastic connection assembly 14;

[0039] The mounting seat 13 is installed on the tooling; the mounting seat 13 is connected to the nozzle fixing assembly 12 through the elastic connecting assembly 14; the nozzle assembly 11 is installed on the nozzle fixing assembly 12, and the nozzle assembly 11 sprays water mist toward the part to be cleaned of the tooling to generate a reaction force. The reaction force causes the nozzle fixing assembly 12 to drive the nozzle assembly 11 to swing relative to the mounting seat 13, and at the same time causes the elastic connecting assembly 14 to produce elastic deformation to limit the swing amplitude of the nozzle fixing assembly 12.

[0040] When the nozzle of this embodiment is used to clean the tooling to be cleaned, the nozzle assembly 11 sprays water mist toward the part to be cleaned of the tooling, and the impact force of the water mist and the action of the tooling produce a reaction force; because the nozzle fixing assembly 12 on which the nozzle assembly 11 is installed is connected to the mounting seat 13 through the elastic connecting assembly 14, that is, the nozzle fixing assembly 12 has a certain degree of freedom, the reaction force will cause the nozzle fixing assembly 12 to drive the nozzle assembly 11 to swing relative to the mounting seat 13, and at the same time, the elastic connecting assembly 14 will be elastically deformed; the elastic connecting assembly 14 that undergoes elastic deformation has a reaction force on the nozzle fixing assembly 12 with a larger swing amplitude, so as to prevent the nozzle assembly 11 from swinging beyond the range of the swing amplitude, and limit the nozzle fixing assembly 12, so that the nozzle assembly 11 can clean the part to be cleaned within a relatively suitable range. Compared with the nozzle with a fixed arrangement of the current nozzle assembly 11, this embodiment expands the cleaning range without additionally setting a driving member. If the nozzle of this embodiment is installed on the impeller of the range hood, it can effectively solve the problem that the current nozzle cannot completely clean the impeller of the range hood, thereby improving the cleaning degree.

[0041] Furthermore, the nozzle fixing assembly 12 is arranged above the mounting seat 13; the nozzle assembly 11 sprays water mist toward the part to be cleaned located below the mounting seat 13 to generate a reaction force, and the reaction force causes the nozzle fixing assembly 12 to drive the nozzle assembly 11 to swing up and down relative to the mounting seat 13, and at the same time causes the elastic connection assembly 14 to deform to limit the swing range of the nozzle fixing assembly 12 up and down.

[0042] Taking into account the specific usage scenarios of the nozzle of this embodiment, for example, the part to be cleaned of the workpiece is lower than the installation position of the mounting seat 13, then the nozzle assembly 11 must be lower than the installation position of the mounting seat 13. Therefore, in order to achieve the swing of the nozzle assembly 11, the nozzle fixing assembly 12 is arranged above the mounting seat 13, and the nozzle assembly 11 is installed on one end of the nozzle fixing assembly 12 away from the mounting seat 13, and the injection port of the nozzle assembly 11 faces the part to be cleaned.

[0043] When the nozzle assembly 11 sprays water mist, the impact force of the water mist collides with the cleaning position to generate a reaction force. The reaction force causes the nozzle fixing assembly 12 to drive the nozzle assembly 11 to swing up and down relative to the mounting seat 13, and at the same time causes the elastic connection assembly 14 to produce elastic deformation to limit the swing amplitude of the nozzle fixing assembly 12 up and down, ensuring that the nozzle assembly 11 can use a position to be cleaned as the midpoint and flush the position of the midpoint attachment back and forth, thereby achieving the purpose of comprehensive cleaning of the tooling and improving the cleaning degree.

[0044] In addition, in order to increase the cleaning time of the nozzle assembly 11 for the initial position to be cleaned (that is, the position to be cleaned opposite to the nozzle assembly 11 when the nozzle assembly 11 has not swung), the elastic connection assembly 14 does not undergo linear elastic deformation, that is, the larger the elastic deformation of the elastic connection assembly 14, the more the reaction force generated does not increase linearly, which enables the nozzle assembly 11 to clean the initial position to be cleaned with a high probability.

[0045] When the installation position of the mounting seat 13 is higher than the position to be cleaned, there will inevitably be edges and corners on the tooling, so in order to better fit with the tooling, the nozzle fixing assembly 12 includes a first fixing member 123 and a second fixing member 124; the end of the first fixing member 123 is connected to the second fixing member 124 to form a first angle; the nozzle assembly 11 is also installed on the first fixing member 123; the second fixing member 124 is connected to the mounting seat 13 through the elastic connection assembly 14. The size of the first angle is determined according to the actual situation, and is usually less than 180°.

[0046] The nozzle fixing assembly 12 is also provided with a first connecting plate 122; the end of the first connecting plate 121 away from the nozzle fixing assembly 12 faces the mounting seat 13, and the first connecting plate 122 is connected to the mounting seat 13 through the elastic connecting assembly 14. The purpose of the first connecting plate 122 is to provide the nozzle fixing assembly 12 with a greater degree of freedom of movement. In a specific embodiment, the first connecting plate 122 is provided at the connection between the first fixing member 123 and the second fixing member 124, and the first connecting plate 122 and the second fixing member 124 are connected in one piece.

[0047] Furthermore, the nozzle of this embodiment further includes a limiter assembly 15; the limiter assembly 15 is installed between the nozzle fixing assembly 12 and the mounting seat 13, and is used to limit the up and down swinging range of the nozzle fixing assembly 12 relative to the mounting seat 13, in order to further limit the degree of freedom of the nozzle fixing assembly 12, and to prevent the up and down swinging range of the nozzle fixing assembly 12 from exceeding a reasonable range. For example, if the nozzle of this embodiment is installed on the impeller of a range hood, it is necessary to prevent the nozzle assembly 11 from colliding with the hub, and at this time, the up and down swinging range of the nozzle fixing assembly 12 is limited so that the nozzle assembly 11 swings up and down between the hubs.

[0048] like Figure 3As shown, the limit assembly 15 includes an upper limit member 151 and a lower limit member 152; the upper limit member 151 is slidably connected with the lower limit member 152. The upper limit member 151 is an L-shaped limit plate, and the corresponding lower limit member 152 is an inverted L-shaped limit plate; the upper end of the upper limit member 151 is mounted on the second fixing member 124, and the lower end of the lower limit member 152 is mounted on the mounting seat 13. At this time, the lower part of the upper limit member 151 is buckled with the upper part of the lower limit plate 152. When the second fixing member 124 swings up and down relative to the mounting seat 13, the upper limit member 151 is slidably connected with the lower limit plate 152.

[0049] like Figure 4 As shown, further, the elastic connection assembly 14 includes a first elastic member 141; the mounting seat 13 includes a mounting plate 133 and a second connecting plate 132; the second connecting plate 132 is connected to the mounting plate 133; the mounting plate 133 is installed on the tooling; the second connecting plate 132 is connected to the first connecting plate 122 through the first elastic member 141. The second connecting plate 132 is arranged at the end of the mounting plate 133, and forms a third angle with the mounting plate 133. The degree of the third angle is determined according to actual conditions, and is usually an obtuse angle.

[0050] like Figure 4 As shown, the first elastic member 141 includes a first elastic portion 1411 and a second elastic portion 1412; one end of the first elastic portion 1411 is connected to one end of the second elastic portion 1412 to form a second angle; the first connecting plate 122 is inserted into the first elastic portion 1411 along the axial direction of the first elastic portion 1411; the second connecting plate 132 is inserted into the second elastic portion 1412 along the axial direction of the second elastic portion 1412, which can not only enable the nozzle fixing assembly 12 to swing relative to the mounting seat 13, but also limit the swing amplitude of the nozzle fixing assembly 12.

[0051] The elastic connection assembly 14 also includes a second elastic member 142; the end of the nozzle fixing member 12 away from the nozzle assembly 11 is connected to the second elastic member 142; the end of the mounting seat 13 away from the nozzle assembly 11 is also connected to the second elastic member 142. The second elastic member 142 is preferably a special-shaped spring, the elastic deformation of the spring is large, and the increase in force is not linear, so as to ensure that the spray range of the nozzle assembly 11 is still concentrated at a certain position, and the proportion of the spray time around this position is relatively reduced. In addition, the spring is in a natural state in the initial state.

[0052] Furthermore, the nozzle assembly 1 includes a nozzle 111 and a nozzle 112; the nozzle 112 is mounted on the nozzle fixing assembly 12; the nozzle 111 is mounted at the water outlet of the nozzle 112; the water inlet of the nozzle 112 is connected to a water source. The nozzle 112 is an L-shaped structure, the vertical end of which is mounted on the first fixing member 123, and the horizontal end of which is mounted with the nozzle 111, and the nozzle 111 sprays water mist toward the position to be cleaned.

[0053] Working process:

[0054] The water from the water source flows through the spray 112 to the nozzle 111, and the nozzle 111 sprays water toward the part to be cleaned of the tooling. The impact force of the water mist and the part to be cleaned generate a reaction force; the reaction force drives the first fixing member 123 and the second fixing member 124, and drives the nozzle assembly 11 to move upward relative to the mounting plate 133. During the movement, the second elastic member 142 is stretched and the first elastic member 141 is compressed, but the second angle is reduced. At this time, the first elastic member 141 and the second elastic member 142 have a downward force on the second fixing member 124, so that the second fixing member 124 and the nozzle assembly 11 move up and down within a controllable range to increase the cleaning range. Because the second elastic member 142 is a special-shaped spring, it will not undergo linear elastic deformation, so the cleaning time duty cycle of the initial part to be cleaned is increased.

[0055] Example 2

[0056] like Figure 5 As shown, this embodiment provides a cleaning system, including the nozzle 1 of embodiment 1, the water cup 2 and the pumping member 3; the pumping member 3 is arranged in the water flow path between the water cup 2 and the nozzle 1, and is used to pump water from the water cup 2 to the nozzle 1.

[0057] When the cleaning system of this embodiment is needed to clean the tooling, the nozzle 1 is aimed at the part to be cleaned, and the pumping member 3 is started. The pumping member 3 pumps the water in the water cup 2 to the nozzle 112, and the water passes through the nozzle 111 to form a water mist and is sprayed to the part to be cleaned. The impact force of the water mist and the part to be cleaned generate a reaction force; the reaction force drives the first fixing member 123 and the second fixing member 124, and drives the nozzle assembly 11 to move upward relative to the mounting plate 133. During the movement, the second elastic member 142 is stretched and the first elastic member 141 is compressed, but the second angle is reduced. At this time, the first elastic member 141 and the second elastic member 142 have a downward force on the second fixing member 124, so that the second fixing member 124 and the nozzle assembly 11 move up and down within a controllable range to increase the cleaning range. Because the second elastic member 142 is a special-shaped spring, it will not undergo linear elastic deformation, so the cleaning time duty cycle of the initial part to be cleaned is increased.

[0058] The water pumping member 3 is preferably a water pump.

[0059] Furthermore, the cleaning system also includes a heating element 4 having a heating chamber; the heating element 4 is arranged in the water flow path between the pumping element 3 and the nozzle 1, and is used to generate high-temperature steam and transport the high-temperature steam to the nozzle 1.

[0060] The pumping element 3 pumps the water in the water cup 2 into the heating chamber of the heating element 4. After the water is heated, high-temperature steam is generated. The high-temperature steam flows to the nozzle 1 through the water flow path, and the high-temperature steam is sprayed by the nozzle 111 to the part to be cleaned.

[0061] Example 3

[0062] like Figure 6-Figure 8 As shown, this embodiment provides a range hood, including the cleaning system of embodiment 2, and a range hood body 5 ; the cleaning system is installed on the range hood body 5 and is electrically connected to the controller of the range hood body 5 .

[0063] The range hood of this embodiment has an automatic cleaning function. When the user starts the automatic cleaning function of the range hood, the controller controls the water suction component 3 (such as a water pump) of the cleaning system to start, and the water in the water cup 2 is sucked out and sprayed toward the range hood body 5 through the nozzle 1, thereby realizing automatic cleaning of the range hood body 5.

[0064] Because the nozzle 1 of this embodiment adopts the nozzle of embodiment 1, the mounting plate 133 is mounted on the volute during specific use, and the nozzle 111 is inserted into the volute and aligned with the impeller. When the pumping member 3 is activated, the water in the water cup 2 is pumped to the nozzle 1, and the water is sprayed through the nozzle 111 to form water mist, which is sprayed toward the impeller, causing the impeller to rotate. The impact force of the water mist and the impeller generate a reaction force; the reaction force drives the first fixing member 123 and the second fixing member 124, and drives the nozzle assembly 11 to move upward relative to the mounting plate 133. During the movement, the second elastic member 142 is stretched and the first elastic member 141 is compressed, but the second angle is reduced. At this time, the first elastic member 141 and the second elastic member 142 have a downward force on the second fixing member 124, so that the second fixing member 124 and the nozzle assembly 11 move up and down within a controllable range to increase the cleaning range, so that the water mist can also clean the edge of the impeller and the hub. Because the second elastic member 142 is a special-shaped spring, it will not undergo linear elastic deformation, thereby increasing the cleaning time duty cycle of the initial part to be cleaned, while preventing the nozzle 111 from colliding with the wheel hub and generating noise.

[0065] When the impeller needs to be cleaned with high-temperature steam, the pumping member 3 pumps the water from the water cup 2 into the heating chamber of the heating member 4. The controller controls the heating part to start, heats the water in the heating chamber, and generates high-temperature steam. The high-temperature steam is sprayed toward the impeller, the edge of the impeller, and the hub through the nozzle 111 to achieve high-temperature oil melting, thereby further improving the cleaning effect.
