[0045] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0046] This application proposes a desktop range hood, combined with... Figures 1 to 6 As shown, the desktop range hood includes an electronic control board 3000 and potting compound 1600, with the potting compound 1600 encapsulating the electronic control board 3000.

[0047] In this embodiment, the electronic control board 3000 is encapsulated with potting compound 1600, which protects the electronic control board 3000. During the cleaning of the desktop range hood, due to the isolation provided by the potting compound 1600, water is unlikely to come into contact with the electronic control board 3000, thus achieving water and electricity separation during the cleaning of the desktop range hood, preventing the electronic control board 3000 from being damaged by water, and laying the foundation for the whole machine water washing of the desktop range hood.

[0048] Specifically, the electronic control board 3000 is a core component for controlling the operation of the desktop range hood. As an electrical component, it receives and processes signals, controlling the operation of the range hood according to preset programs and logic. For example, the electronic control board 3000 includes a PCB board and resistors, capacitors, diodes, etc., integrated on the PCB board. In related technologies, the electronic control board 3000 is located inside the desktop range hood. When cleaning the range hood, water can easily come into contact with the electronic control board 3000, potentially causing damage. Therefore, in this embodiment, potting compound 1600 is used to achieve water and electricity isolation of the electronic control board 3000. Encapsulant 1600 is an insulating material. For example, encapsulant 1600 includes, but is not limited to, epoxy resin encapsulant, silicone encapsulant, or polyurethane encapsulant. Encapsulant 1600 encapsulates the control board 3000. It can be understood that encapsulation in this article means that encapsulant 1600 wraps around the electrically connected parts of the control board 3000, thereby achieving water and electricity isolation of the control board 3000. For example, the entire control board 3000 can be encapsulated. In this way, when cleaning the desktop range hood, even if water flows towards the control board 3000, the presence of encapsulant 1600 will prevent water from contacting the control board 3000, effectively preventing the control board 3000 from being damaged by water. In addition, the presence of encapsulant 1600 can also enhance the heat dissipation of the control board 3000.

[0049] The desktop range hood uses a 5000 fan to extract cooking fumes. The power for this extraction comes from the 5000 fan. Figure 7 and Figure 8 As shown, in some embodiments, the desktop range hood includes a fan 5000. The fan 5000 rotates to extract fumes. Generally, the fan 5000 includes a volute, a impeller, and a motor. The impeller is rotatably mounted inside the volute. The motor shaft is connected to the impeller, and the motor drives the impeller to rotate within the volute, thus extracting fumes. The fumes enter from the air inlet of the desktop range hood and exit from the air outlet 1001. The operation of the fan 5000 requires control by an electronic control board 3000. Therefore, the desktop range hood includes a first connecting line 6100. One end of the first connecting line 6100 is connected to the fan 5000, specifically to the motor of the fan 5000. The other end of the first connecting line 6100 is connected to the electronic control board 3000, thus enabling the electronic control board 3000 to control the rotation of the fan 5000. In addition, the potting compound 1600 is used to encapsulate the connection between the first connecting line 6100 and the electronic control board 3000.

[0050] Combination Figure 7 and Figure 8 As shown, in some embodiments, the desktop range hood includes a body 1000, which has a wind cavity 1003 and a first mounting cavity 1100. A fan 5000 is mounted in the wind cavity 1003, and an electronic control board 3000 is mounted in the first mounting cavity 1100. A partition 1300 is provided between the wind cavity 1003 and the first mounting cavity 1100. The wind cavity 1003 is a space for mounting the fan 5000. When the desktop range hood exhausts fumes, the fumes enter the wind cavity 1003 and then the interior of the fan 5000, and are then discharged from the fan 5000 and out of the wind cavity 1003. The first mounting cavity 1100 is a space for mounting the electronic control board 3000. In this embodiment, the partition 1300 separates the wind cavity 1003 from the first mounting cavity 1100, preventing fumes from entering the first mounting cavity 1100 during exhaust. It is understandable that the shape of the partition 1300 can be regular or irregular. The structure that is set between the air cavity 1003 and the first mounting cavity 1100 to serve as a separator can be regarded as the partition 1300. The partition 1300 separates the air cavity 1003 and the first mounting cavity 1100, so that the oil fumes mainly flow along the air cavity 1003, preventing the oil fumes from polluting the installation space of the electronic control board 3000.

[0051] Understandably, given the partition 1300, in order to shorten the length of the first connecting line 6100, the first connecting line 6100 is designed to pass through the partition 1300, meaning the first connecting line 6100 is in a state of passing through the partition 1300. For example, the first connecting line 6100 is first connected to the fan 5000, and after the fan 5000 is installed in place, the first connecting line 6100 is then passed through the partition 1300 to connect to the electrical control board 3000. This arrangement helps to shorten the length of the first connecting line 6100 and reduce costs.

[0052] The first connecting line 6100 passing through the partition 1300 means that the partition 1300 has a corresponding perforated structure. The existence of the perforated structure implies a risk of water leakage. Therefore, the first connecting line 6100 passes through the partition 1300 in the following manner. Combined with... Figure 8 As shown, in some embodiments, the partition 1300 is provided with a through hole, and the desktop range hood also includes a sealing sleeve 1500. The sealing sleeve 1500 is provided in the through hole, and the first connecting line 6100 passes through the sealing sleeve 1500. By providing the sealing sleeve 1500, the first connecting line 6100 can pass through, and a seal can be formed at the through hole to prevent water leakage.

[0053] Specifically, the sealing sleeve 1500 is elastic, thus adaptable to elastic deformation. When the sealing sleeve 1500 is placed in the through hole, it deforms to abut against the wall of the through hole. Alternatively, it can be understood as an interference fit between the sealing sleeve 1500 and the through hole. Similarly, the sealing sleeve 1500 has a perforated structure, through which the first connecting line 6100 passes. The interference fit between the first connecting line 6100 and the sealing sleeve 1500 achieves a tight fit, thus sealing between them. This design ensures waterproofing at the through hole, preventing water leakage. For example, when cleaning the air chamber 1003 and the fan 5000, water is unlikely to flow into the first mounting cavity 1100 from the through hole.

[0054] Combination Figure 8 In some embodiments, at least a portion of the first connecting line 6100 is fixed to the surface of the fan 5000. It is understood that since the fan 5000 is located in the air cavity 1003, there is airflow in the air cavity 1003 when the desktop range hood is exhausting oil fumes. Therefore, in this embodiment, at least a portion of the first connecting line 6100 is fixed to the surface of the fan 5000, which can prevent the airflow from blowing the first connecting line 6100 and avoid increasing noise.

[0055] For example, the first connecting line 6100 includes a first line segment 6110 and a second line segment 6120. The first line segment 6110 is connected to the motor of the fan 5000 and is arranged along the surface of the fan 5000 (such as the volute). The second line segment 6120 is connected to the electronic control board 3000. The first line segment 6110 and the surface of the fan 5000 can be connected and fixed by means of adhesive, bundling or other methods.

[0056] Optionally, in some embodiments, the motor of the fan 5000 is a waterproof motor. Waterproof motors can be found in related technologies. Waterproof motors have a certain degree of waterproof performance, which can achieve the rinsing of the air cavity 1003 and the fan 5000.

[0057] Combination Figure 9 and Figure 10 As shown, the desktop range hood includes a control panel 4000 for user interaction. The control panel 4000 can be equipped with buttons 4100 for user operation. These buttons 4100 include, but are not limited to, buttons, knobs, touchscreens, or sensors. Through the control panel 4000, users can control the desktop range hood's on / off and adjustment. Furthermore, the control panel 4000 can display the status of the desktop range hood, such as indicating its current operating status, like fan speed or mode.

[0058] The commands generated by the user operating the control panel 4000 need to be transmitted to the electronic control board 3000. The electronic control board 3000 processes these commands to control the operation of the desktop range hood. Therefore, the desktop range hood includes a second connecting cable 6200. One end of the second connecting cable 6200 is connected to the control panel 4000, and the other end of the second connecting cable 6200 is connected to the electronic control board 3000. In this way, the commands generated by the control panel 4000 can be transmitted to the electronic control board 3000. On this basis, the potting compound 1600 also needs to encapsulate the connection between the second connecting cable 6200 and the electronic control board 3000.

[0059] Combination Figure 9 and Figure 10 As shown, in some embodiments, the desktop range hood includes a body 1000 and a mounting base 1400. The body 1000 is provided with a first mounting cavity 1100 and a second mounting cavity 1200. The first mounting cavity 1100 is provided with a first opening 1110, and the second mounting cavity 1200 is provided with a second opening 1120. The second mounting cavity 1200 is connected to the first mounting cavity 1100 through the second opening 1120. A control panel 4000 is disposed in the second mounting cavity 1200, and an electronic control board 3000 is disposed in the mounting base 1400. The mounting base 1400 covers the second opening 1120 to close the second mounting cavity 1200, so that the electronic control board 3000 is disposed in the first mounting cavity 1100.

[0060] By setting the first opening 1110 and the second opening 1120, when installing the electronic control board 3000 and the control panel 4000 onto the machine body 1000, the control panel 4000 can first be installed into the second mounting cavity 1200 by passing through the first opening 1110 and the second opening 1120. Then, the mounting base 1400 and the electronic control board 3000 can be installed into the first mounting cavity 1100 by passing through the first opening 1110. The mounting base 1400 and the electronic control board 3000 can be installed into the first mounting cavity 1100 in sequence, or the mounting base 1400 and the electronic control board 3000 can be assembled together first and then installed into the first mounting cavity 1100. After the mounting base 1400 is installed into the first mounting cavity 1100, the mounting base 1400 covers the second opening 1120, thereby closing the second mounting cavity 1200. At this time, the second mounting cavity 1200 forms a nearly closed space, which can prevent water from entering the second mounting cavity 1200 and causing damage to the control panel 4000 when cleaning the desktop range hood.

[0061] The control panel 4000 can be fixed to the second mounting cavity 1200 by means of screws or other methods. Similarly, the mounting base 1400 and the electronic control board 3000 can be fixed to the first mounting cavity 1100 by means of screws or other methods. The mounting base 1400 and the electronic control board 3000 can also be fixed to each other by means of screws or other methods. The electronic control board 3000 is mounted on the mounting base 1400, for example, on the upper surface of the mounting base 1400. The potting compound 1600 can cover the electronic control board 3000 and the mounting surface of the mounting base 1400, thereby encapsulating the electronic control board 3000, the connection between the electronic control board 3000 and the first connecting line 6100, and the connection between the electronic control board 3000 and the second connecting line 6200.

[0062] Understandably, when the mounting base 1400 is installed, in order to reduce the length of the second connecting line 6200, the second connecting line 6200 needs to pass through the mounting base 1400. In this case, the potting compound 1600 also needs to cover the position where the second connecting line 6200 passes through the mounting base 1400, that is, to seal the hole structure on the mounting base 1400 to prevent water leakage.

[0063] In some embodiments, the mounting base 1400 is designed to be detachable, meaning it can be installed into and removed from the first mounting cavity 1100, for example, by screw connection. This detachable design facilitates maintenance of the control board 3000. Since the mounting base 1400 covers the second opening 1120, removing the mounting base 1400 also facilitates maintenance of the control panel 4000. Based on the detachable design of the mounting base 1400, this embodiment incorporates a sealing strip (not shown in the figure). The sealing strip can be a silicone strip, rubber strip, sponge strip, etc., and is positioned between the mounting base 1400 and the periphery of the second opening 1120 to achieve a seal and prevent water leakage during cleaning of the desktop range hood.

[0064] Combination Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, in some embodiments, the first mounting cavity 1100 and the second mounting cavity 1200 are located on the top of the body 1000. It is understood that when the desktop range hood is exhausting fumes, the fan 5000 will accumulate grease, which will flow downwards under gravity. Therefore, a collection box 2200 is usually installed below the fan 5000 to temporarily collect the grease. In this embodiment, the first mounting cavity 1100 and the second mounting cavity 1200 are located on the top of the body 1000, thus offsetting them from the collection box 2200, which facilitates the structural layout.

[0065] Furthermore, combined Figure 9 and Figure 10 As shown, in some embodiments, the first mounting cavity 1100 is located above the second mounting cavity 1200, and the first opening 1110 is open upwards. The orientation in this document is based on the desktop range hood being placed on the support surface. The side of the desktop range hood closest to the support surface is the bottom, and the side away from the support surface is the top. With this arrangement, during the production and assembly stage of the desktop range hood, the body 1000 can be in an upright state while the power control board 3000 and control panel 4000 are assembled, making it more convenient for workers to operate.

[0066] Combination Figure 6 and Figure 10As shown, in some embodiments, the control board 3000 is provided with a power port 3100, which is used to receive power, such as a power adapter plugged into the power port 3100 to power the desktop range hood. Since the control board 3000 is installed on the body 1000, the power port 3100 is exposed from the side of the body 1000, rather than on other parts, which helps to reduce the misalignment error between components. Similarly, when the control panel 4000 is installed on the body 1000, the buttons 4100 of the control panel 4000 are exposed from the side of the body 1000, rather than on other parts, which helps to reduce the misalignment error between components.

[0067] Combination Figure 7 and Figure 9 As shown, in some embodiments, the desktop range hood includes a body 1000, which is provided with a wind cavity 1003, an air outlet 1001, and a mounting port 1002. The air outlet 1001 is located above the wind cavity 1003, and the mounting port 1002 is located below the wind cavity 1003. With this arrangement, the entire desktop range hood can be washed by water, provided that the electronic control board 3000 is encapsulated.

[0068] Specifically, the desktop range hood includes an oil collection box 2200, which is detachably connected to the bottom of the body 1000 and covers the mounting port 1002. When the desktop range hood exhausts fumes, the oil accumulated on the fan 5000 falls into the oil collection box 2200 under the action of gravity. The desktop range hood also includes a top cover 2100, which is detachably connected to the top of the body 1000 and covers the electronic control board 3000. The top cover 2100 forms part of the external structure of the desktop range hood, shielding the electronic control board 3000 and preventing the exhaust fumes from contaminating it. For example, the top cover 2100 may cover the entire top of the desktop range hood (the top cover 2100 has a perforated structure corresponding to the air outlet 1001). A filter element 2300 is typically installed between the top cover 2100 and the air outlet 1001.

[0069] When cleaning the desktop range hood, the top cover 2100 and oil collection box 2200 can be removed. The air outlet 1001 can be aligned with a water tap, allowing water to flow into the air chamber 1003 and flush the impeller of the fan 5000. The impeller's rotation cleans the fan 5000's casing, and the waste liquid is discharged from the mounting port 1002 into the water tank and then down the drain. Alternatively, the top cover 2100 and oil collection box 2200 can be removed, and the mounting port 1002 aligned with a water tap. Water flows into the air chamber 1003 and flushes the impeller of the fan 5000, cleaning the fan 5000's casing. The waste liquid is discharged from the air outlet 1001 into the water tank and then down the drain. This arrangement facilitates comprehensive cleaning of the desktop range hood, improves the user experience, and makes cleaning the desktop range hood more convenient.
