The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0035] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0036] In order to solve the problem in the prior art that the infrared receiving rate of the infrared receiving head installed in the housing is low and affects the user experience, the present application provides an infrared receiving component and a heater having the same.

[0037] like Figures 1 to 7 As shown, the infrared receiving assembly includes a housing 10 and an infrared receiving head 20. The housing 10 has a reflection channel 11 that penetrates the housing 10. The infrared receiving head 20 is located on the inner side of the housing 10, and at least part of the infrared receiving head 20 extends into the reflection channel 11. The inner surface of the reflection channel 11 includes at least two inclined reflection surfaces 111 that are arranged opposite to each other, and the distance between the at least two inclined reflection surfaces 111 gradually increases along the direction S from the inner side to the outer side of the housing 10.

[0038] By applying the technical solution of this embodiment, the light emitted by the infrared transmitter (remote control) is reflected by the inclined reflecting surface 111 on the reflecting channel 11, and the reflected light is irradiated on the infrared receiving head 20 to realize the preset function of the household appliance (heater). The above-mentioned setting of at least two inclined reflecting surfaces 111 makes the receiving range of the infrared receiving head 20 an open range, thereby expanding the receiving range of the infrared receiving head 20 and improving the infrared receiving rate, thereby solving the problem in the prior art that the infrared receiving rate of the infrared receiving head 20 installed in the shell is low and affects the user experience, thereby improving the user experience.

[0039] like Figure 4 and Figure 5 As shown, the reflection channel 11 has a first channel opening 112 formed on the outer surface of the housing 10 and a second channel opening 113 formed on the inner surface of the housing 10, and the orthographic projection of the first channel opening 112 on the second channel opening 113 is located inside the second channel opening 113. In this way, the above-mentioned arrangement of the first channel opening 112 and the second channel opening 113 can effectively reduce the interference of the external environment on the infrared signal, and can ensure the stable reception of the infrared signal.

[0040] Specifically, by limiting the projection position of the first channel opening 112, dust and other impurities can be prevented from entering the shell 10 through the first channel opening 112 and causing the equipment in the shell 10 to be contaminated. This ensures that the infrared receiving head 20 can receive infrared signals while improving the dustproof effect of the infrared receiving component. It can also prevent dust from adhering to the infrared receiving head 20 and affecting its normal use, thereby improving the infrared reception rate of the infrared receiving component.

[0041] like Figure 5 As shown, along the direction S from the inside to the outside of the housing 10, the reflection channel 11 includes a first hole segment 114 and a second hole segment 115 that are interconnected, and at least two oppositely arranged inclined reflection surfaces 111 form at least part of the hole wall of the second hole segment 115; wherein the first channel opening 112 is arranged at one end of the first hole segment 114 away from the second hole segment 115, and the second channel opening 113 is arranged at one end of the second hole segment 115 away from the first hole segment 114, and the infrared receiving head 20 extends into the first hole segment 114. In this way, the above-mentioned segmented design of the reflection channel 11 can further optimize the reflection path of the infrared signal and improve the sensitivity and accuracy of infrared signal reception.

[0042] In this embodiment, the first hole segment 114 is a straight hole segment, the infrared receiving head 20 extends into the first hole segment 114, and the second hole segment 115 is a reflective hole. The above arrangement of the first hole segment 114 and the second hole segment 115 improves the structural strength of the housing 10 at the reflective channel 11, thereby extending the service life of the housing 10. At the same time, by arranging the first hole segment 114 to accommodate part of the infrared receiving head 20, the infrared receiving head 20 can be protected.

[0043] Optionally, the depth h of the reflection channel 11 is greater than or equal to 5.5 mm and less than or equal to 6.5 mm; and / or the hole depth of the first hole segment 114 is greater than or equal to 1.0 mm and less than or equal to 1.5 mm. In this way, by adjusting the depth h of the reflection channel 11 and the hole depth of the first hole segment 114, the reflection and transmission effects of the infrared signal can be optimized, so that the device can stably receive the signal at different distances and angles to ensure complete reception of the signal.

[0044] In this embodiment, the depth h of the reflection channel 11 is 6.0 mm, and the hole depth of the first hole section 114 is 1.2 mm, so as to further optimize the reflection and transmission effects of the infrared signal and improve the infrared receiving rate of the infrared receiving component.

[0045] It should be noted that the depth h of the reflection channel 11 is not limited to this, and can be adjusted according to working conditions and usage requirements. Optionally, the depth h of the reflection channel 11 is 5.8 mm or 6.2 mm.

[0046] It should be noted that the hole depth of the first hole section 114 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the hole depth of the first hole section 114 is 1.1 mm or 1.4 mm.

[0047] like Figure 4 As shown, at least two inclined reflection surfaces 111 disposed opposite to each other include a first inclined reflection surface 1111 and a second inclined reflection surface 1112, and the hole wall of the second hole segment 115 includes two connecting surfaces disposed opposite to each other, the first inclined reflection surface 1111 and the second inclined reflection surface 1112 are located between the two connecting surfaces, the two sides of the first inclined reflection surface 1111 are respectively connected to the connecting surfaces, and the two sides of the second inclined surface are respectively connected to the connecting surfaces. In this way, the above arrangement enables a stable signal reflection space to be formed in the reflection channel 11, thereby improving the signal reception stability and reliability. At the same time, the above arrangement makes the structure of the second hole segment 115 simpler, easier to process and realize, and reduces the processing cost and difficulty of the second hole segment 115.

[0048] In this embodiment, both connecting surfaces are inclined surfaces and the inclination angles are smaller than the inclination angles of the first inclined reflection surface 1111 and the second inclined reflection surface 1112 , so as to further increase the infrared signal receiving range.

[0049] Optionally, the connection between the first inclined reflective surface 1111 and the connection surface is rounded; and / or the connection between the second inclined reflective surface 1112 and the connection surface is rounded. In this way, the above-mentioned rounded corners can not only reduce the loss of infrared signals during the reflection process and improve the signal reception efficiency, but also optimize the signal reflection angle, so that the signal is transmitted more smoothly in the reflection channel 11, thereby improving the infrared reception accuracy of the device.

[0050] In this embodiment, the connection between the first inclined reflecting surface 1111 and the connecting surface is rounded, and the connection between the second inclined reflecting surface 1112 and the connecting surface is rounded.

[0051] Optionally, the second channel opening 113 is a quadrilateral hole or a waist-shaped hole; and / or, the first channel opening 112 is a quadrilateral hole or a waist-shaped hole. In this way, the above-mentioned opening design can effectively control the receiving range of the infrared signal and improve the receiving accuracy and directionality of the infrared signal. At the same time, the above-mentioned setting makes the opening shape selection of the second channel opening 113 and / or the first channel opening 112 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0052] In this embodiment, the second channel opening 113 and the first channel opening 112 are both waist-shaped holes.

[0053] Optionally, the second channel opening 113 is rounded. In this way, the rounded corner processing can not only further reduce the loss of infrared signals during the receiving process, improve the receiving efficiency and stability of infrared signals, but also optimize the angle at which the signal enters the infrared receiving head 20.

[0054] In this embodiment, the housing 10 is arc-shaped, and the reflection channel 11 is located at the top of the arc. In this way, the arc design can optimize the reflection path of the infrared signal and improve the signal reception efficiency and range. At the same time, the reflection channel 11 set at the top of the arc is equivalent to the protruding setting of other parts of the housing 10, which makes it easier to receive infrared signals and further improves the infrared reception rate of the infrared receiving component.

[0055] Optionally, the infrared receiving assembly further includes a driving device. The driving device is connected to the infrared receiving head 20 to adjust the length of the infrared receiving head 20 extending into the reflecting channel 11. In this way, by driving the infrared receiving head 20 to move through the driving device, the receiving range and angle of the infrared signal can be adjusted according to actual needs, thereby improving the adaptability and flexibility of the device, and greatly improving the control convenience and user experience of the device.

[0056] Optionally, the infrared receiving component further includes a control module and a speaker. The control module is electrically connected to the infrared receiving head 20, and the speaker is electrically connected to the control module. After the infrared receiving head 20 receives the control signal, the speaker is controlled by the control module to emit a sound signal. In this way, the speaker can remind the user that the infrared receiving head 20 has received the control signal, thereby improving the intelligence of the device and the user experience.

[0057] Specifically, after issuing a remote control command, the user can immediately hear the response sound of the device to confirm whether the command is received correctly, which improves the user's interactive experience and the operational transparency of the device, making remote control of the device more intuitive and reliable.

[0058] Optionally, the length of the second channel opening 113 is greater than or equal to 17 mm and less than or equal to 20 mm, and the width of the second channel opening 113 is greater than or equal to 3 mm and less than or equal to 5 mm; and / or, the length of the first channel opening 112 is greater than or equal to 12 mm and less than or equal to 15 mm, and the width of the second channel opening 113 is greater than or equal to 2 mm and less than 3 mm. In this way, by precisely controlling the size of the second channel opening 113 and the first channel opening 112, the reception effect of the infrared signal can be further optimized, the reception accuracy and directionality of the signal can be improved, and the safety of the device and the user experience can be improved. At the same time, the above-mentioned setting makes the size selection of the second channel opening 113 and / or the first channel opening 112 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0059] In this embodiment, the second channel opening 113 has a length of 18.3 mm and a width of 3.6 mm, and the first channel opening 112 has a length of 13.3 mm and a width of 2.8 mm.

[0060] It should be noted that the length of the second channel opening 113 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the length of the second channel opening 113 is 17.5 mm, or 17.8 mm, or 18.0 mm, or 18.5 mm, or 18.8 mm, or 19.0 mm, or 19.5 mm, or 19.8 mm.

[0061] It should be noted that the width of the second channel opening 113 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the width of the second channel opening 113 is 3.2 mm, or 3.5 mm, or 3.8 mm, or 4.0 mm, or 4.2 mm, or 4.5 mm, or 4.8 mm.

[0062] It should be noted that the length of the first channel opening 112 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the length of the first channel opening 112 is 12.2 mm, or 12.5 mm, or 12.8 mm, or 13.0 mm, or 13.5 mm, or 13.8 mm, or 14.0 mm, or 14.2 mm, or 14.5 mm, or 14.8 mm.

[0063] It should be noted that the width of the first channel opening 112 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the width of the first channel opening 112 is 2.2 mm, or 2.5 mm, or 2.9 mm.

[0064] Optionally, a reflective film is disposed on the inclined reflective surface 111. In this way, the above-mentioned arrangement of the reflective film can further improve the reflection effect of the signal, reduce the loss of the signal during the reflection process, and improve the reception efficiency and stability of the signal.

[0065] like Figures 1 to 7 As shown, the present application also provides a heater, including the above-mentioned infrared receiving component.

[0066] Optionally, the heater is an electric heater.

[0067] It should be noted that, in addition to being used in heaters, the above-mentioned infrared receiving component can also be applied to other product series that are common to the same principle, such as remote-controlled humidifiers, etc.

[0068] like Figure 6 As shown, the fan heater includes a display panel 30, an infrared receiving head 20 of the infrared receiving assembly is arranged on the display panel 30, and a housing 10 of the infrared receiving assembly is located in front of the display panel 30. Thus, the housing 10 is the front housing of the fan heater.

[0069] Specifically, when using infrared remote control for human-computer interaction, when the user stands on the left side of the heater and uses the remote control, the infrared light forms an incident angle with the inclined reflecting surface of the infrared receiving component. After reflection, the infrared light will be reflected along the reflection angle into the infrared receiving head 20. The infrared receiving head 20 completes the remote control after receiving the operation command signal.

[0070] In this embodiment, the infrared receiving component is located at the upper end of the front shell.

Among them, the inner surface of the reflection channel includes at least two inclined reflection surfaces arranged opposite to each other, and the distance between the at least two inclined reflection surfaces gradually increases along the direction S from the inner side to the outer side of the shell. In this way, the light emitted by the infrared transmitter (remote control) is reflected by the inclined reflection surface on the reflection channel, and the reflected light is irradiated on the infrared receiving head to realize the preset function of the household appliance (heater), and the above-mentioned setting of at least two inclined reflection surfaces makes the receiving range of the infrared receiving head an open range, thereby expanding the receiving range of the infrared receiving head and improving the infrared receiving rate, thereby solving the problem that the infrared receiving rate of the infrared receiving head installed in the shell in the prior art is low and affects the user experience, thereby improving the user experience.
