[0032] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0033] Reference is made below to the attached Figures 1 to 8 Describe the heating component, the indoor unit of the air conditioner, and the air conditioner of the embodiment of the present utility model.
[0034] As Figures 1 to 5 and Figure 8 shown, the heating component of the embodiment of the present utility model includes: an evaporator bracket 1, an electric control module 7 (not shown), and a heating module 2. The evaporator bracket 1 is used to be installed at the end of the evaporator 3. A wire routing portion 11 is provided on the evaporator bracket 1. The heating module 2 includes a heater 21 and a heating wire 22. The heater 21 and the electric control module 7 are respectively arranged on both sides in the thickness direction of the evaporator bracket 1. One end of the heating wire 22 is electrically connected to the heater 21 and is arranged adjacent to the evaporator bracket 1. The other end of the heating wire 22 is electrically connected to the electric control module 7. The heating wire 22 is fixed on the wire routing portion 11.
[0035] For the heating component according to the embodiment of the present utility model, since one end of the heating wire 22 is electrically connected to the heater 21 and is arranged adjacent to the evaporator bracket 1, and the other end of the heating wire 22 is electrically connected to the electric control module 7, it can be made such that the wire outlet position of the heater 21 is closer to the electric control module 7, reducing the layout length of the heating wire 22. In addition, since the heating wire 22 is fixed on the wire routing portion 11, the heating wire 22 can be fixed to avoid the problem of the heating wire 22 shaking relative to the evaporator bracket 1. Therefore, the heating component of the embodiment of the present utility model not only reduces the layout length of the heating wire 22 but also fixes the layout of the heating wire 22, which is beneficial to reducing electrical safety hazards and has a lower cost.
[0036] It can be understood that the wire outlet position of the heater 21 is arranged adjacent to the evaporator bracket 1. Since the electric control module 7 is arranged on the other side in the thickness direction of the evaporator bracket 1, the wire outlet position of the heater 21 can be made closer to the electric control module 7 to reduce the layout length of the heating wire 22. Compared with the scheme of routing the heating wire 22 around the evaporator 3 or the base 5 in the present application, the layout length of the heating wire 22 can be greatly reduced. For example, the heating wire 22 can cross over (bypass) or pass through the evaporator bracket 1 to be connected to the electric control module 7.
[0037] In the example of the present application, the electric control module 7 is the electric control module 7 of the whole indoor unit of the air conditioner.
[0038] Alternatively, as Figure 4 and Figure 5 As shown, the wiring portion 11 includes a wiring trough 111, which is provided on the side of the evaporator support 1 facing the heater 21. At least a portion of the heating wires 22 are arranged within the wiring trough 111. This conceals the heating wires 22 arranged on the evaporator support 1, preventing interference between the heating wires 22 and other components (e.g., the impeller) and reducing the wiring space required for the heating wires 22. It should be noted that the extension path of the wiring trough 111 can be designed based on the layout path of the heating wires 22, and this application does not specifically limit the shape and length of the wiring trough 111.
[0039] To further enhance the securement of the heater wire 22, the wiring portion 11 further includes a snap (not shown) positioned at the notch of the wiring groove 111. The snap and the wiring groove 111 together define a snap-fit channel within which the heater wire 22 is snapped. This prevents the heater wire 22 from slipping out of the wiring groove 111, improves the securement of the heater wire 22, and facilitates assembly and disassembly.
[0040] In other examples, the wiring portion 11 further includes a plurality of wire clips (not shown), which are arranged in sequence along the extension path of the heating wire 22 , and the plurality of wire clips are clipped to the heating wire 22 to fix the heating wire 22 on the evaporator bracket 1 .
[0041] Alternatively, as Figures 3 to 5 As shown, the wiring portion 11 further includes a wire outlet hole 112, which is provided at the end of the wiring trough 111 facing away from the heater 21. The wire outlet hole 112 extends through the evaporator support 1 along the thickness direction of the evaporator support 1. It will be appreciated that the heater wire 22 passes through the evaporator support 1 through the wire outlet hole 112 to connect with the electronic control module 7, thereby further shortening the layout length of the heater wire 22. The wire outlet hole 112 also constrains the direction and position of the heater wire 22 for better installation security.
[0042] In order to avoid the problem of air leakage or condensation water penetration at the position of the wire outlet hole 112, the inner side surface of the wire outlet hole 112 can be abutted against the base 5 so that the base 5 blocks the inner side of the wire outlet hole 112 without affecting the normal conduction between the wire outlet hole 112 and the wiring groove 111, that is, the heating wire 22 can pass through the wire outlet hole 112 normally from the wiring groove 111.
[0043] In one example, if Figures 3 to 5As shown, a notch 1121 is provided at the upper end of the wire outlet hole 112. The notch 1121 communicates with the wire outlet hole 112, and the notch 1121 is arranged with a gradually expanding opening in the upward direction. The heating wire 22 can be snapped into the wire outlet hole 112 from the position of the notch 1121, which facilitates the assembly work of the heating wire 22. In addition, since the notch 1121 is arranged with a gradually expanding opening in the upward direction, it can provide guidance for the snap connection of the heating wire 22, further improving the assembly efficiency of the heating wire 22.
[0044] Optionally, as Figure 2 , Figure 3 and Figure 6 shown, the wire routing portion 11 further includes a wire routing buckle 113. The wire routing buckle 113 is provided on the side of the evaporator bracket 1 facing the electronic control module 7. A wire passing hole 1131 is provided in the wire routing buckle 113, and the heating wire 22 is passed through the wire passing hole 1131. It can be understood that the heating wire 22 passing out of the wire outlet hole 112 is fixed by the wire routing buckle 113, and then the heating wire 22 is extended into the electronic control module 7 to avoid the problem of the heating wire 22 shaking relative to the evaporator bracket 1.
[0045] Specifically, as Figure 3 shown, the wire routing buckle 113 and the wire outlet hole 112 are arranged at intervals in the front-back direction of the evaporator bracket 1. In other words, the wire routing buckle 113 is located on the front side of the wire outlet hole 112. The heating wire 22 has a bent section 221. The bent section 221 is arranged between the wire outlet hole 112 and the wire routing buckle 113. The structure of the bent section 221 is U-shaped (V-shaped) and protrudes towards the lower end of the evaporator bracket 1. It can be understood that the bent section 221 of the heating wire 22 can closely adhere to the outer wall surface of the evaporator bracket 1 under the constraint of the wire outlet hole 112 and the wire routing buckle 113. Since the bent section 221 of the heating wire 22 is U-shaped and protrudes towards the lower end of the evaporator bracket 1, the condensed water generated on the evaporator bracket 1 can flow down along the bent section 221 into the water receiving tray 6, improving the drainage effect of the condensed water. On the other hand, since the heating wire 22 is arranged in the above structure, it can prevent the condensed water from entering the electronic control module 7 along the extending direction of the heating wire 22, which is beneficial to reducing the electrical safety hazard of the electronic control module 7.
[0046] In an example, as Figure 2 and Figure 3 shown, a convex column 12 is provided on the evaporator bracket 1. The convex column 12 protrudes in the direction away from the heater 21. An insertion interface 121 is provided at one end of the convex column 12 facing the heater 21. The heater 21 has an insertion joint, and the insertion joint is installed in the insertion interface 121. It can be understood that the end (insertion joint) of the heater 21 is inserted and matched with the insertion interface 121 on the evaporator bracket 1 to facilitate the installation and disassembly of the heater 21.
[0047] As Figures 6 to 8As shown, the indoor air conditioner of another embodiment of the present utility model includes a frame body 4, an evaporator 3, a base 5, and a heating component. The frame body 4 is provided with an air inlet 41 and an air outlet 42. The evaporator 3 is installed on the base 5, and the frame body 4 is connected to the base 5. The heating component is the heating component of the embodiment of the present utility model. The evaporator bracket 1 and the electronic control module 7 are installed on the same side in the length direction of the evaporator 3. For example, both the evaporator bracket 1 and the electronic control module 7 are located on the left side of the evaporator 3.
[0048] For the indoor air conditioner according to the embodiment of the present utility model, since one end of the heating wire 22 is electrically connected to the heater 21 and is arranged adjacent to the evaporator bracket 1, and the other end of the heating wire 22 is electrically connected to the electronic control module 7, the wire outlet position of the heater 21 can be made closer to the electronic control module 7, reducing the layout length of the heating wire 22. In addition, since the heating wire 22 is fixed on the wire routing portion 11, the heating wire 22 can be fixed to avoid the problem of the heating wire 22 shaking relative to the evaporator bracket 1. Therefore, the indoor air conditioner of the embodiment of the present utility model not only reduces the layout length of the heating wire 22, but also fixes the layout of the heating wire 22, which is beneficial to reducing electrical safety hazards and has a lower cost.
[0049] Optionally, as Figure 7 shown, the air inlet 41 is provided on the lower end surface of the frame body 4, the evaporator 3 protrudes in the direction of the air inlet 41, and the front wall surface of the frame body 4 is open to form the air outlet 42. For example, in the projection plane orthogonal to the length direction of the base 5, the cross-section of the evaporator 3 is V-shaped, and the tip of the evaporator 3 is arranged towards the air inlet 41. It can be understood that the air flow entering the indoor air conditioner from the air inlet 41 below the frame body 4 can exchange heat with the V-shaped wall surface of the evaporator 3, and the air flow after heat exchange can be discharged through the air outlet 42, thereby improving the heat exchange effect of the indoor air conditioner.
[0050] In the example of the present application, since the air inlet 41 is provided on the lower end surface of the frame body 4 and the front wall surface of the frame body 4 is open to form the air outlet 42, the indoor air conditioner of the embodiment of the present utility model can be installed against the ceiling. It can be understood that since the air in the environment does not need to enter the interior of the indoor air conditioner from directly above the frame body 4, the distance between the indoor air conditioner and the top wall (ceiling) of the room can be greatly reduced or eliminated, thereby improving the space utilization rate of the room. Especially for rooms with a relatively low height, the cramped feeling of the indoor space can be effectively reduced or eliminated. Therefore, the indoor air conditioner of the embodiment of the present utility model has very low requirements for the installation space, and the installation space only needs to be able to accommodate the indoor air conditioner, without leaving an air inlet space or an air outlet space above the indoor air conditioner, thereby expanding the applicable range of the indoor air conditioner.
[0051] An air conditioner according to another embodiment of the present utility model includes an outdoor unit and an indoor unit. The indoor unit is the indoor unit of the present utility model, and the indoor unit is connected to the outdoor unit. The technical advantages of the air conditioner according to the embodiment of the present utility model are the same as those of the heating component and the indoor unit in the above embodiment, and will not be elaborated here.
