[0025] To make the possible application scenarios, technical principles, specific schemes that can be implemented, purposes and effects that can be achieved of the present application clear, the following will be described in detail in combination with the specific embodiments listed and the accompanying drawings. The embodiments described in the present document are only used to more clearly illustrate the technical schemes of the present application, and therefore only serve as examples, and cannot be used to limit the protection scope of the present application.

[0026] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0027] The technical schemes in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application.

[0028] The embodiments of the present application provide a remote controller to solve the problem that the remote controller is difficult to send infrared signals to an air conditioner at a relatively far position. The following will be described in combination with the accompanying drawings.

[0029] Please refer to Figure 1 The embodiments of the present application provide a remote controller, which includes a first housing 1, a second housing 2 and an infrared emission head 3. The first housing 1 is provided with an inclined surface 11 at one end in a first direction, the inclined surface 11 connects two sides of the first housing 1 in a second direction, and the inclined surface 11 is inclinedly arranged along the second direction. The second housing 2 is arranged on one side of the first housing 1 away from the second direction.

[0030] It should be noted that in the present embodiment, the first direction is the length direction of the first housing 1, and the second direction is the thickness direction of the first housing 1.

[0031] Please refer to Figure 2 and Figure 3, the inclined surface 11 is provided with a containing groove 12, the infrared emission head 3 is fixedly connected to the groove bottom of the containing groove 12, and the infrared emission head 3 at least partially extends out of the containing groove 12. In the embodiment, the containing groove 12 is a circular groove, the normal line of the groove bottom of the containing groove 12 is arranged along the first direction, and since the containing groove 12 is arranged on the inclined surface 11, the length of the groove wall of the containing groove 12 gradually shortens along the second direction. The side wall of the containing groove 12 is arranged to be inclined from the groove bottom of the containing groove 12 to the opening direction of the containing groove 12. In some embodiments of the application, the side wall of the containing groove 12 is arranged in an elliptical curved surface shape, and the infrared emission head 3 is arranged at the focal point of the elliptical curved surface, so that the infrared signal with the invalid deflection angle only needs to be reflected once to be emitted out of the containing groove 12.

[0032] Please refer to Figure 2 and Figure 3 By gradually shortening the length of the groove wall of the containing groove 12 along the second direction, the groove wall on the side of the containing groove 12 away from the second direction can reflect more infrared signals emitted in the invalid direction to the effective direction, thereby enhancing the intensity of the infrared signal in the effective direction; since the length of the groove wall of the containing groove 12 close to the side of the second direction is short, the reflected infrared signal can be emitted out of the containing groove 12 from the side of the second direction, thereby reducing the attenuation of the infrared signal caused by multiple reflections of the infrared signal on the groove wall of the containing groove 12.

[0033] Please refer to Figure 2 and Figure 3 The included angle between the inclined surface 11 and the side of the first shell 1 in the second direction is α, and 30°≤α≤50°. In the embodiment, the value of α is 35°, and in some embodiments of the application, the value of α is any one of 30°, 40°, 45° and 50°. The included angle between the side wall of the containing groove 12 and the groove bottom of the containing groove 12 is β, and 65°≤β≤75°. In the embodiment, the value of β is 65°, and in some embodiments of the application, the value of β is any one of 70° and 75°. By making 30°≤α≤50° and 65°≤β≤75°, it is not only conducive to the reflection of the infrared signal with the invalid deflection angle, but also conducive to improving the coverage range of the infrared signal.

[0034] Please refer to Figure 2 The distance between the side of the infrared emission head 3 away from the groove bottom of the containing groove 12 and the end of the first shell 1 away from the first direction is h1, the length of the side of the first shell 1 in the second direction is h2, and the length of the side of the first shell 1 away from the second direction is h3, and h2

[0035] In addition, the slot wall of the accommodating slot 12 is provided with a reflection layer having high infrared signal reflectivity, which reduces the absorption of the infrared signal by the slot wall of the accommodating slot 12, thereby facilitating the transmission of the infrared signal to a farther position.

[0036] In summary, by providing the inclined surface 11 at one end of the first housing 1 and the accommodating slot 12 for accommodating the infrared emitter head 3 on the inclined surface 11, the length of the one side slot wall of the accommodating slot 12 in the direction away from the second direction is greater than the length of the one side slot wall of the accommodating slot 12 in the second direction, so that the one side slot wall of the accommodating slot 12 in the direction away from the second direction can reflect more infrared signals having the ineffective deflection angle emitted by the infrared generator into infrared signals having the effective deflection angle, thereby enhancing the intensity of the infrared signals having the effective deflection angle, so that the infrared signals can be transmitted to a farther position, thereby solving the problem that the remote controller is difficult to transmit the infrared signals to the air conditioner at a farther position.

[0037] In the above embodiments, the description of each embodiment is focused on, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0038] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, the patent protection scope of the present application should not be limited. Any technical solutions obtained by replacing or modifying the equivalent structure or equivalent process based on the essential concept of the present application, using the content described in the specification and drawings of the present application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
