Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted heating equipment, in particular to a vehicle-mounted heating machine. Background Art

[0002] Most of the car heating devices currently used on the market use a single air duct, which makes it difficult to achieve uniform output of warm air in the front and back or left and right positions in the car, causing the overall temperature in the car to rise evenly, and users cannot feel the comfortable heating needs in the car.

[0003] Therefore, improvements need to be made to this. Utility Model Content

[0004] The technical problem solved by the present invention is to provide a vehicle-mounted heater in view of the defects existing in the above-mentioned prior art, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A vehicle-mounted heater, comprising: a shell, wherein a accommodating space is provided in the shell; a main air duct, wherein the main air duct is arranged inside the shell, and a heat source for generating heat and a fan for sucking in external air are provided in the main air duct; a first branch air duct, wherein the first branch air duct is connected to the main air duct, and the first branch air duct is used to transport the heated air to one side outside the shell; a second branch air duct, wherein the second branch air duct is connected to the main air duct, and the second branch air duct is arranged opposite to the first branch air duct, and the second branch air duct is used to transport the heated air to the other side outside the shell.

[0006] Furthermore, the first branch air duct and the second branch air duct are symmetrically distributed.

[0007] Furthermore, the main air duct, the first branch air duct and the second branch air duct are integrated.

[0008] Furthermore, the main air duct, the first branch air duct and the second branch air duct form a T-shape or a Y-shape.

[0009] Furthermore, the shell is made of high-temperature resistant nylon flame retardant material.

[0010] Furthermore, the heat source is a far-infrared ceramic heating element.

[0011] Compared with the existing technology, the beneficial effects of the present invention are: the use of dual air ducts to transport hot air can evenly increase the overall temperature in the car, meeting the needs of comfortable heating. At the same time, the use of high-efficiency far-infrared ceramic heating elements can quickly heat up and provide stable heat. The fan uses a high-speed fan, which has stable operation and does not produce excessive noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "several" or "multiple" means two or more, unless otherwise specifically defined. In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. A person skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them. Furthermore, "above," "above," and "above" a first feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher level than the second feature. "Below," "below," and "below" a first feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a lower level than the second feature.

[0019] In view of the technical problems recorded in the background technology, as shown in the figure, a vehicle-mounted heater 4 is provided, including: a shell 1, wherein the shell 1 has a accommodating space; a main air duct 2, wherein the main air duct 2 is arranged inside the shell 1, and the main air duct 2 is provided with a heat source 3 for generating heat and a fan 4 for sucking in external air; a first branch air duct 5, wherein the first branch air duct 5 is communicated with the main air duct 2, and the first branch air duct 5 is used to transport the heated air to one side outside the shell 1; a second branch air duct 6, wherein the second branch air duct 6 is communicated with the main air duct 2, and the second branch air duct 6 is arranged opposite to the first branch air duct 5, and the second branch air duct 6 is used to transport the heated air to the other side outside the shell 1.
