Description

Technical Field

[0001] This utility model belongs to the field of heater technology, and in particular to an indoor heater. Background Technology

[0002] The power cord outlet of an indoor heater is usually located in the middle of the unit. The wire core connected to the motor is thinner, while the wire core connected to the heating element is thicker. The two have a large price difference, which increases the cost. In addition, the heating element needs to be fixed separately to the housing, which increases the installation process and further increases the cost. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an indoor heater that reduces costs.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An indoor heater, comprising:

[0006] The housing has a cavity for housing a motor. The housing has a first limiting wall and a second limiting wall, which are partial boundaries of the cavity. The first limiting wall, the second limiting wall, and the arc-shaped wall of the housing form an air outlet channel. The housing is provided with a cable outlet.

[0007] A heating assembly is disposed on the first limiting wall and the second limiting wall, and is positioned above the air outlet channel. The heating assembly has an air outlet and a limiting step disposed on the outer periphery of the air outlet. The wire outlet is disposed near the heating assembly.

[0008] The face frame has a first through hole through which the air outlet passes, and the face frame is pressed against the limiting step to restrict the movement of the heating component;

[0009] The panel has a second through hole, and the air outlet extends into the second through hole.

[0010] In the above-mentioned indoor heater, the housing is provided with a support step, the support step includes a first support part and a first limiting part, the first support part is provided with two limiting protrusions, and the heating component is partially disposed between the two limiting protrusions to restrict the heating component from moving in two directions toward the limiting protrusions. The first limiting part is used to restrict the heating component from moving in the direction of the first limiting part.

[0011] In the above-mentioned indoor heater, both the first limiting wall and the second limiting wall are provided with limiting grooves. The limiting grooves have a second support part and a second limiting part. The second support part is used to support the heating component, and the second limiting part is used to restrict the movement of the heating component toward the second limiting part. The first limiting part, the second limiting part, and the two limiting protrusions restrict the movement of the heating component.

[0012] In the aforementioned indoor heater, the heating component is detachably mounted on the first limiting wall, the second limiting wall, and the supporting step.

[0013] In the aforementioned indoor heater, the outlet section is located at the arc-shaped wall position.

[0014] The aforementioned indoor heater also includes a protective shell, which has a wire outlet hole. The protective shell is detachably installed on the housing to cover the wire outlet.

[0015] In the aforementioned indoor heater, the chamber is used to install a motor and a worm gear.

[0016] Compared with the prior art, this application has the following advantages:

[0017] In this application, the wire outlet is located near the heating element, which minimizes the path of the thick wire core and reduces the cost increase caused by wire waste. The heating element is placed directly above the first and second limiting walls, and its bottom is pressed against the limiting step to achieve self-positioning. The frame is fixed by pressing against the limiting step with through holes, eliminating the need for additional fasteners or bolts, simplifying the assembly process and shortening the assembly time. Both the frame and the panel have through holes corresponding to the air outlet of the heating element, which facilitates modular assembly and reduces the use of fasteners in this position, thus lowering the cost.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, an indoor heater includes: a housing 2, a heating assembly 3, a frame 4, and a panel 5. The housing 2 has a chamber 23 for mounting a motor 100. The housing 2 also has a first limiting wall 21 and a second limiting wall 22, which form part of the boundary of the chamber 23. The first limiting wall 21, the second limiting wall 22, and the arc-shaped wall 28 of the housing 2 together form an air outlet channel 24. A wiring outlet 25 is provided on the housing 2. The heating assembly 3 is disposed on the first limiting wall 21. The heating assembly 3 is located above the air outlet 24 and above the second limiting wall 21 and the second limiting wall 22. The heating assembly 3 has an air outlet 31 and a limiting step 32 located on the outer periphery of the air outlet 31. The wire outlet 25 is located near the heating assembly 3. The face frame 4 has a first through hole 41 through which the air outlet 31 passes, and the face frame 4 is pressed against the limiting step 32 to restrict the movement of the heating assembly 3. The panel 5 has a second through hole 51 into which the air outlet 31 extends.

[0035] In this application, the wire outlet 25 is located near the heating component 3, which minimizes the path of the thick wire core and reduces the cost increase caused by wire waste. The heating component 3 is placed directly above the first limiting wall 21 and the second limiting wall 22, and its bottom is pressed and engaged with the limiting step 32 to achieve self-positioning. The through hole of the face frame 4 is used to press and fix it with the limiting step 32, eliminating the need for additional fasteners or bolts, simplifying the assembly process and shortening the assembly time. Both the face frame 4 and the panel 5 are provided with through holes, corresponding to the air outlet 31 of the heating component 3, which facilitates the overall modular assembly, reduces the use of fasteners at this position, and lowers the cost.

[0036] Specifically, the housing 2 is provided with a support step 26, which includes a first support part 261 and a first limiting part 262. The first support part 261 is provided with two limiting protrusions 2611. The heating component 3 is partially disposed between the two limiting protrusions 2611 to restrict the heating component 3 from moving in two directions toward the limiting protrusions 2611. The first limiting part 262 is used to restrict the heating component 3 from moving in the direction of the first limiting part 262.

[0037] Two limiting protrusions 2611 form bidirectional limiting on the first support 261, which can accurately constrain the position of the heating component 3 in the horizontal plane. The first limiting part 262 forms additional constraint on the heating component 3 in the vertical direction, which can also limit the displacement of the heating component 3.

[0038] The supporting step 26 and the limiting protrusion 2611 are both integrally molded, requiring no additional fasteners or adjustment steps. During assembly, the heating component 3 simply "clicks in" and automatically takes place, significantly shortening assembly time. This reduces the use of external fasteners such as screws, and the integrated structure reduces mold complexity and the number of parts, which is beneficial for production efficiency and cost control.

[0039] Specifically, both the first limiting wall 21 and the second limiting wall 22 are provided with limiting grooves 27. Each limiting groove 27 has a second support portion 271 and a second limiting portion 272. The second support portion 271 is used to support the heating component 3, and the second limiting portion 272 is used to restrict the heating component 3 from moving toward the second limiting portion 272. The first limiting portion 262, the second limiting portion 272, and the two limiting protrusions 2611 restrict the movement of the heating component 3.

[0040] The second support portion 271 and the second limiting portion 272 of the limiting groove 27 work together with the first support portion 261, the limiting protrusion 2611 and the first limiting portion 262 to constrain the heating component 3 in both horizontal and vertical directions. Together with the limiting step 32 and the two limiting protrusions 2611, they jointly realize the movement limitation of the heating component 3 on the horizontal plane.

[0041] Furthermore, the second support portion 271 of the limiting groove 27 is connected to the first support portion 261 of the support step 26 and is at the same height.

[0042] Specifically, the heating component 3 is detachably installed on the first limiting wall 21, the second limiting wall 22, and the supporting step 26.

[0043] The heating component 3 can be placed directly on the first limiting wall 21, the second limiting wall 22 and the supporting step 26. After the face frame 4 is installed, the face frame 4 presses it against the limiting step 32 of the heating component 3, thereby completely limiting the heating component 3.

[0044] Specifically, the cable outlet 25 is located at the position of the arc-shaped wall 28.

[0045] Specifically, it also includes a protective shell 6, which has a cable outlet hole 61. The protective shell 6 is detachably mounted on the housing 2 to cover the cable outlet 25.

[0046] The removable protective cover 6 blocks the cable outlet 61, preventing users from accidentally touching the cable outlet 25 and reducing the risk of electric shock; it effectively isolates the cable from contact with external foreign objects, preventing foreign objects from entering and causing short circuits or sparks.

[0047] Specifically, chamber 23 is used to install motor 100 and worm gear. This part is prior art; motor 100 drives worm gear to rotate, drawing airflow into heating assembly 3 for heating.

[0048] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0049] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
