Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to an operating device and a range hood. Background Art

[0002] As people's requirements for quality of life become higher and higher, people pay more and more attention to the convenience of home appliance operation and the aesthetics of the operating device. Traditional mechanical buttons have been gradually eliminated due to noise and lifespan issues.

[0003] Some existing operating devices use infrared or other methods to detect user operations. These operating devices usually do not have mechanical buttons, but use infrared to detect whether the user's finger is close to the operating icon (the operating icon does not have the function of pressing the operation, but only serves as a prompt). In this way, even if there are stains or water drops on the user's hands, it will not affect the detection result of the operating device.

[0004] Taking the operating device on the range hood as an example, the infrared detection probe is located in front of the operating icon and higher than the operating icon. The infrared detection probe is directed downward to detect whether the user's finger is close to or in contact with the operating icon. However, it is difficult for the infrared detection probe to accurately control its detection range within the height range from the infrared detection probe to the operating icon, and it is usually larger than this height range. As a result, even if the operation is not performed at the operating icon, the corresponding function may be triggered. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, an embodiment of the utility model provides an operating device. The operating device includes an operating panel and a detection probe. An operating icon is arranged on the operating panel. The detection probe is located outside the operating panel and is arranged corresponding to the operating icon, the positive projection of the detection probe on the operating panel is spaced apart from the corresponding operating icon, and the detection probe faces the corresponding operating icon.

[0006] The operation icon can prompt the user to use the electrical key function of the operation device when touching or approaching the operation icon. The detection probe is located obliquely in front of the corresponding operation icon, so that the corresponding operation icon will not be blocked, and the effective detection range that the finger can enter can be limited to between the detection probe and the corresponding operation icon. Therefore, it can effectively avoid the occurrence of malfunctions caused by the detection range of the detection probe being too large.

[0007] Exemplarily, the operation panel includes a transparent portion, and the operation icon is arranged in the transparent portion.

[0008] The operation icons can be set on the transparent part by printing, silk-screen printing, engraving, etc., and can be located on the side facing away from the user, or inside the transparent part. In this way, the user will only touch the surface of the operation panel during operation, and will not touch the operation icons. This will not cause wear and corrosion of the operation icons, and the icons will be clear and understandable even after long-term use.

[0009] Exemplarily, the transparent portion extends to the edge of the operation panel, and the operation device further includes an indicator light corresponding to the operation icon, which is located on the side of the edge of the operation panel and faces the corresponding operation icon.

[0010] The transparent part shines on the operation icon. The operation icon adopts an inner carving pattern, which gives people a visual effect that the operation icon itself is glowing. Therefore, the inner carving pattern with the indicator light can be more technological and improve the user experience.

[0011] Exemplarily, the operating device also includes a detection shell having a groove recessed inward from its outer surface, the edge of the operating panel is inserted into the groove, the indicator light is located in the groove and between the bottom surface of the groove and the side of the edge of the operating panel.

[0012] The groove on the detection housing can also fix the operation panel and make the appearance of the operation device more concise. The indicator light arranged here can illuminate the button icon through the operation panel. Therefore, there is no need to arrange indicator lights on other sides of the operation panel, making the operation device more concise.

[0013] Exemplarily, the edge of the operating panel is sealingly connected to the groove.

[0014] This can prevent water vapor and oil from invading the inside of the groove through the gap between the two, affecting the operation of the indicator light and the light transmission effect of the edge of the operation panel.

[0015] Exemplarily, the operation icon includes an engraved pattern engraved inside the transparent portion.

[0016] The inner carved pattern is more ornamental and will not form uneven marks on the surface of the operation panel, will not harbor dirt, and is easy for users to clean.

[0017] Exemplarily, the inner engraved pattern is inclined toward the outer side of the operation panel along a direction away from the indicator light.

[0018] The tilting of the inner carving pattern can make the entire inner carving pattern illuminated, and the inner carving close to the light source will not block the light, so there will be no situation where the side close to the indicator light is brighter and the side far from the indicator light is darker.

[0019] Exemplarily, the operating device further includes a detection shell having a groove sunken inward from an outer surface thereof, an edge of the operating panel is inserted into the groove, and the detection probe is located in the detection shell.

[0020] The detection housing can prevent erosion by oil, dirt and water vapor. The groove on the detection housing can also fix the operation panel and make the appearance of the operation device more concise.

[0021] Exemplarily, a window is provided on the shell, and the window is located on a straight line between the detection probe and the corresponding operation icon.

[0022] The window is used to transmit the detection wave of the detection probe, which can alleviate or prevent the components in the detection housing from being exposed to the environment and contaminated with oil and dust without affecting the detection effect.

[0023] Exemplarily, there are multiple operation icons, which are spaced apart from each other; there are multiple detection probes, and detection ranges formed by the multiple detection probes on the operation panel do not overlap with each other.

[0024] Users can accurately touch or approach the operation icon, and there is basically no false detection, which provides a good user experience.

[0025] Exemplarily, a control board is disposed in the detection housing, and the indicator light and the detection probe are electrically connected to the control board.

[0026] The control panel can control the electrical appliance using the operating device to perform corresponding actions according to the signal sent by the detection probe. The control panel can also control the indicator light of the corresponding operation icon to light up after detecting that the corresponding action is performed.

[0027] Exemplarily, the detection probe includes an infrared sensor.

[0028] Infrared sensors have low cost, long life, good reliability, and are not easily affected by external interference. They can detect the presence and movement of objects within a certain range.

[0029] Exemplarily, the detection probe is located on the outside of the top of the operation panel.

[0030] The detection probe is closer to the user than the detection panel. On the one hand, it is convenient for the user to operate; on the other hand, the detection probe can be set diagonally downward to avoid the accumulation of oil on the detection probe.

[0031] The utility model also provides a range hood, comprising an operating device, wherein the operating device is located on the front of the range hood. The operation of the range hood can be controlled by the operating device, which is convenient for users to use.

[0032] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0041] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0042] The embodiment of the utility model provides an operating device. The operating device can be applied to any suitable equipment including but not limited to range hoods, integrated stoves, etc. The operating device of the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0043] like Figure 1 As shown, the operating device may include an operating panel 100, and an operating icon 110 may be provided on the operating panel 100. The operating panel 100 may be made of glass or metal. The operating icon 110 may be provided on the surface of the operating panel 100 by any suitable method such as coating, pasting, printing, laser marking, etching, etc., or may be processed inside the operating panel 100 by laser engraving, etc. It can be understood that the operating icon 110 on the operating panel 100 may only be used to guide the user to operate, and does not have an actual detection function. In order to detect the user's action, the operating device may also include a detection probe 200, and the detection probe 200 may be located outside the operating panel 100 and arranged corresponding to the operation icon 110. Exemplarily, the detection probe 200 may include detectors such as an infrared detection switch, an ultrasonic probe, and a microwave radar, and may detect the presence or absence of an object within a certain range and the movement of the object. Exemplarily, the detection probe 200 may include an infrared sensor. The infrared sensor has a low cost, a long life, good reliability, and is not easily affected by external interference.

[0044] exist Figure 1 In the specific embodiment shown, there may be six operation icons 110, and in this case, six detection probes 200 are also provided, and the detection probes 200 correspond one to one with the operation icons 110. Figure 2a , Figure 2b and Figure 3, the detection probe 200 is located outside the operation panel 100. The detection probe 200 is closer to the user than the operation panel 100. The positive projection of the detection probe 200 on the operation panel 100 is spaced apart from the corresponding operation icon 110. For kitchen appliances, the operation panel 100 is usually placed vertically. The positive projection of the detection probe 200 on the operation panel 100 is set to be spaced apart from the corresponding operation icon 110, so as to avoid the detection probe 200 from blocking the operation icon 110. In the illustrated embodiment, the detection probe 200 is arranged above the corresponding operation icon 110. In other embodiments not shown, the detection probe 200 can be arranged at various oblique fronts such as obliquely below, obliquely to the left, or obliquely to the right of the corresponding operation icon 110. In short, it is expected that the detection probe 200 does not visually block the operation icon 110. It can be understood that there is a certain distance between the detection probe 200 and the operation icon 110. The detection probe 200 faces the corresponding operation icon 110, and can detect whether there is a touch object (such as a finger) in the area between the detection probe 200 and the operation icon 110. The detection range of the detection probe 200 can be a cone that expands from the detection probe 200 toward the corresponding operation icon 110. The operation icon 110 is located within the detection range of the cone. When the touch object enters the conical detection range from the gap between the detection probe 200 and the operation icon 110, the detection probe 200 generates a corresponding signal, so that the electrical appliance (such as a range hood) using the operation panel 100 can be controlled to perform a corresponding action.

[0045] The operating panel 100 of the operating device provided in the embodiment of the present application is provided with an operating icon 110, and the operating icon 110 can prompt the user to use the electrical key function of the operating device when touching or approaching the operating icon 110. The detection probe 200 is located obliquely in front of the corresponding operating icon 110, so that the corresponding operating icon 110 will not be blocked, and the effective detection range that the finger can enter can be limited to between the detection probe 200 and the corresponding operation icon 110. Therefore, the detection range of the detection probe 200 is too large to cause malfunction.

[0046] For example, Figure 2a and Figure 2b As shown, the operating device may further include a detection housing 400, the detection housing 400 having a groove 410 recessed inward from its outer surface, and the edge of the operating panel 100 may be inserted into the groove 410. The operating device may include components such as a circuit board and a connecting line, and the detection housing 400 may accommodate the above components. The detection probe 200 may also be arranged in the detection housing 400 to prevent erosion by oil and water vapor. The groove 410 on the detection housing 400 may also fix the operating panel 100, and make the appearance of the operating device more concise.

[0047] Exemplarily, a window 500 may be provided on the detection housing 400, and the window 500 is located on a straight line between the detection probe 200 and the corresponding operation icon 110, and the window 500 is used to transmit the detection wave of the detection probe 200. Exemplarily, when the detection probe 200 adopts an ultrasonic probe, the window 500 may be a metal mesh, or simply a hole provided on the detection housing 400. Ultrasonic waves may be transmitted to the outside of the detection housing 400 through the window 500, and ultrasonic waves reflected by the touched object may return to the detection probe 200 through the window 500. When the detection probe 200 adopts an infrared detection switch, the window 500 may be an opening or be formed by a light-transmitting material. In short, the window 500 may be provided to alleviate or prevent the components in the detection housing 400 from being exposed to the environment and contaminated with oil and dust without affecting the detection effect.

[0048] Exemplarily, there may be multiple operation icons 110, and multiple operation icons 110 are arranged at intervals from each other. As described above, each operation icon 110 may correspond to different functions. There may also be multiple corresponding detection probes 200, and the detection ranges formed by the multiple detection probes 200 on the operation panel 100 do not overlap with each other. Exemplarily, the detection probe 200 is an infrared detection switch, which can emit infrared rays and detect the infrared rays reflected back to the infrared detection switch. The irradiation range of the infrared rays can be considered as the detection range of the infrared detection switch. For adjacent detection probes 200, the light spots formed when the infrared rays are irradiated to the operation icons 110 on the operation panel 100 do not overlap with each other. In this way, under the prompt of the operation icon 110, the user can accurately touch or approach the operation icon 110, so basically no false detection will occur, and the user experience is good.

[0049] Exemplarily, the operation panel 100 may include a transparent portion, and the operation icon 110 is disposed on the transparent portion. The operation icon 110 includes an inner carving pattern engraved inside the transparent portion. The inner carving pattern is more ornamental, and will not form uneven marks on the surface of the operation panel 100, will not harbor dirt, and is convenient for users to clean. Of course, the operation icon 110 disposed on the transparent portion may also be formed by other processes, such as by screen printing on the surface of the transparent portion.

[0050] For example, the operation icon 110 can be set on the transparent part by printing, silk-screen printing, engraving, etc., and can be located on the side facing away from the user, or inside the transparent part. In this way, the user only touches the surface of the operation panel 100 during operation, and does not touch the operation icon 110, which does not cause wear and corrosion of the operation icon 110, and is clear and understandable even after long-term use.

[0051] Exemplarily, the transparent portion may extend to the edge of the operation panel 100, and the operation device may further include an indicator light 300 corresponding to the operation icon 110, the indicator light 300 being located on the side of the edge of the operation panel 100 and facing the corresponding operation icon 110. The indicator light 300 may provide feedback to the user. For example, when the user touches or approaches the operation icon 110 and expects the electrical appliance of the operation device to perform the corresponding action, if the action is performed normally, the corresponding indicator light 300 lights up. If the corresponding indicator light 300 is still off, the electrical appliance fails. The user can find out in time through the indicator light 300 on the operation device. The feedback of the indicator light 300 may also improve the user's experience. The light emitted by the indicator light 300 may shine from the side of the operation panel 100 through the transparent portion thereon to the operation icon 110. The operation icon 110 adopts an inner engraving pattern, which is essentially a tiny burst point formed inside the glass, which scatters the light, while other transparent parts do not reflect the light, thereby giving a visual effect that the operation icon 110 itself is luminous. Therefore, the inner carved pattern matched with the indicator light 300 can be more technological and improve the user experience.

[0052] For example, Figure 2a As shown, illustratively, the indicator light 300 can be arranged in the groove 410 and between the groove bottom surface of the groove 410 and the edge of the operation panel 100. As described above, the indicator light 300 can be arranged on the side of the edge of the operation panel 100 and facing the corresponding operation icon 110. When the operation panel 100 is assembled to the groove 410, the groove bottom surface of the groove 410 faces the side of the operation panel 100. At this time, the indicator light 300 arranged here can illuminate the operation icon 110 through the operation panel 100. Therefore, there is no need to arrange the indicator light 300 on other sides of the operation panel 100, so that the operation device is more concise.

[0053] Exemplarily, the edge of the operation panel 100 can be sealed and connected to the groove 410. Exemplarily, the groove 410 can be filled with sealant, and after the edge of the operation panel 100 is inserted into the groove 410, a seal can be formed at the interface between the two. Exemplarily, the edge of the operation panel 100 can be inserted into the groove 410 by interference fit, thereby forming a seal. This can prevent water vapor and oil from invading the interior of the groove 410 from the gap between the two, affecting the operation of the indicator light 300 and the light transmission effect of the edge of the operation panel 100.

[0054] For example, the inner carving pattern can be tilted toward the outside of the operation panel 100 along the direction away from the indicator light 300. Since the light of the indicator light 300 is irradiated from the side of the operation panel 100, the tilt of the inner carving pattern can make the entire inner carving pattern illuminated, and the inner carving close to the light source will not block the light, so there will be no situation where the side close to the indicator light 300 is brighter and the side away from the indicator light 300 is darker.

[0055] Exemplarily, a control panel 420 may be provided in the detection housing 400, and the control panel 420 may be constructed using electronic components such as a timer, a comparator, a register, and a digital logic circuit, or may be implemented using a processor chip such as a single chip microcomputer, a microprocessor, a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), an application specific integrated circuit (ASIC), and its peripheral circuits. The indicator light 300 and the detection probe 200 are both electrically connected to the control panel 420, and the control panel 420 may control the electrical appliance using the operating device to perform the corresponding action according to the signal sent by the detection probe 200. The control panel 420 may also control the indicator light 300 of the corresponding operation icon 110 to light up after detecting that the corresponding action is performed.

[0056] For example, the detection probe 200 may be located outside the top of the operation panel 100. For example, when the operating device is applied to a range hood, the operation panel 100 is usually located at the top of the range hood. The detection probe 200 is arranged outside the top of the operation panel 100. On the one hand, it is convenient for the user to operate; on the other hand, the detection probe 200 can be arranged obliquely downward to avoid the accumulation of oil on the detection probe 200.

[0057] According to another aspect of the utility model, a range hood is also disclosed, which can include any of the above-mentioned operating devices. The operating device can be located on the front of the range hood to facilitate user operation. The range hood using the above-mentioned operating device at least has all the advantages of the above-mentioned operating devices, which will not be described in detail here.
