[0036] In order to solve the problem of low infrared receiving rate of the infrared receiving head installed in the shell in the prior art and affecting the user experience, the present application provides an infrared receiving assembly and a warm air machine having the same.

[0037] As shown in Figures 1 to 7 The infrared receiving assembly includes a housing 10 and an infrared receiving head 20. The housing 10 has a reflection channel 11 penetrating 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. Wherein, the inner surface of the reflection channel 11 includes at least two oppositely arranged inclined reflection surfaces 111, and the distance between the at least two inclined reflection surfaces 111 gradually increases in the direction S from the inner side to the outer side of the housing 10.

[0038] The technical scheme is applied, the light emitted by the infrared emitter (remote controller) is reflected by the inclined reflecting surface 111 on the reflecting channel 11, the reflected light irradiates on the infrared receiving head 20, the preset function of the household appliance (fan heater) is realized, and the receiving range of the infrared receiving head 20 is an open range due to the above-mentioned arrangement of the at least two inclined reflecting surfaces 111, the receiving range of the infrared receiving head 20 is further expanded, the infrared receiving rate is improved, the problem that the infrared receiving rate of the infrared receiving head 20 installed in the shell is low in the prior art and affects the user experience is solved, and the user experience is improved.

[0039] As shown in Figure 4 and Figure 5 The reflecting channel 11 has a first channel opening 112 formed on the outer surface of the shell 10 and a second channel opening 113 formed on the inner surface of the shell 10, and the orthographic projection of the first channel opening 112 on the second channel opening 113 is located in 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 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 are prevented from entering the shell 10 through the first channel opening 112 and polluting the equipment in the shell 10, thereby ensuring that the infrared receiving head 20 can receive the infrared signal while improving the dustproof effect of the infrared receiving assembly and avoiding the attachment of dust on the infrared receiving head 20 affecting its normal use, and the infrared receiving rate of the infrared receiving assembly is improved.

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

[0042] In this embodiment, the first aperture segment 114 is a straight aperture segment into which the infrared receiver head 20 extends. The second aperture segment 115 is a reflective aperture. The aforementioned arrangement of the first aperture segment 114 and the second aperture segment 115 enhances the structural strength of the housing 10 at the reflective channel 11, thereby extending the service life of the housing 10. Simultaneously, by providing the first aperture segment 114 to accommodate part of the infrared receiver head 20, the infrared receiver head 20 can be protected.

[0044] In this embodiment, the depth h of the reflection channel 11 is 6.0 mm, and the hole depth of the first hole segment 114 is 1.2 mm, so as to further optimize the reflection and transmission effect of infrared signals 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 value and can be adjusted according to the working conditions and usage requirements. Optionally, the depth h of the reflection channel 11 is 5.8mm or 6.2mm.

Simultaneously, this arrangement simplifies the structure of the second aperture segment 115, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the second aperture segment 115.

In this way, the arc-shaped design can optimize the reflection path of the infrared signal, improve the receiving efficiency and range of the signal.

In this way, the user can be reminded by the speaker that the infrared receiving head 20 has received the control signal, thereby improving the intelligent degree of the device and the user experience.

[0057] Specifically, after the user sends out a remote control command, the user can immediately hear the response sound of the device, confirming whether the command is correctly received, improving the user's interaction experience and the operation transparency of the device, making the remote control of the device more intuitive and reliable.
