Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an electric heater and an air conditioner. Background Technology

[0002] Nowadays, air conditioners are increasingly accepted by families due to their ease of operation and good cooling / heating performance. Modern air conditioners typically have an internal electric heater, which is an auxiliary heating component mainly used to enhance the heating effect of the air conditioner in low-temperature environments.

[0003] As an auxiliary heating component during heating, the electric heater mainly consists of four parts: heating element, mounting bracket, thermal protector, and power connection cable. In wall-mounted air conditioners, the electric heater is usually installed in the air duct behind the evaporator or in front of the air outlet. Thus, when the indoor environment is low, the electric heater works when the air conditioner is powered on. The airflow is heated after passing through the electric heater, and the air conditioner can blow out hot air, thereby raising the indoor temperature.

[0004] When air conditioners are manufactured in factories, they are assembled on the production line using various components to complete the assembly. When faced with air conditioning units of different specifications, if the same model of electric heater is used for assembly, the power connection cable length requirements for the electric heater will be different for different units. Therefore, the same model of electric heater cannot be used in different units, which increases production costs. Utility Model Content

[0005] This application provides an electric heater and an air conditioner to solve the problem that the same model of electric heater cannot be used with different specifications of air conditioning units due to the different requirements of the power connection wire length for different specifications of air conditioning units.

[0006] In a first aspect, this application provides an electric heater detachably mounted on an air conditioner having a first sidewall, the electric heater comprising:

[0007] A power receiving base is detachably mounted on the first side wall of the air conditioner via a first mounting structure. One end of the power receiving base extends through the first side wall into the interior of the air conditioner and forms a first power receiving part.

[0008] An electric heater body is detachably disposed inside the air conditioner, and one end of the electric heater body forms a second electrical connection that is adapted and connected to the first electrical connection part.

[0009] According to the technical solution provided in the embodiments of this application, a through hole communicating with the interior of the air conditioner is provided on the first side wall, and the first electrical contact part extends through the through hole into the interior of the air conditioner.

[0010] According to the technical solution provided in the embodiments of this application, the first mounting structure includes:

[0011] The first mounting hole has at least two holes, both of which are disposed on the first sidewall and symmetrically distributed on both sides of the through hole;

[0012] The second mounting hole has at least two holes, and each hole is located at the end of the power base away from the first power receiving part. The at least two second mounting holes and the at least two first mounting holes correspond one-to-one.

[0013] The mounting component passes through the second mounting hole and the first mounting hole in sequence to mount the power base on the first side wall.

[0014] According to the technical solution provided in the embodiments of this application, the air conditioner also has a second sidewall opposite to the first sidewall, and the end of the electric heater body away from the second electrical contact part is detachably disposed on the inner wall of the second sidewall through a second mounting structure.

[0015] According to the technical solution provided in the embodiments of this application, the second mounting structure includes:

[0016] A fixing member is fixedly disposed on the inner wall of the second side wall. The fixing member is provided with a snap-fit ​​part for snapping the end of the electric heater body away from the second electrical contact part.

[0017] According to the technical solution provided in the embodiments of this application, the end of the power base away from the first power receiving part is located outside the air conditioner, and the end of the power base away from the first power receiving part forms a power receiving end.

[0018] According to the technical solution provided in the embodiments of this application, the air conditioner is provided with a power supply plug, and the power supply plug and the power receiving terminal can be adapted to be connected for supplying power to the power receiving base.

[0019] Secondly, embodiments of this application also provide an air conditioner, including an electric heater as described in any embodiment.

[0020] The technical solutions provided in this application have the following advantages compared with the prior art:

[0021] The electric heater provided in this application embodiment is detachably installed inside an air conditioner. It includes a power base, which is detachably installed on a first side wall of the air conditioner through a first mounting structure. One end of the power base penetrates the first side wall and extends into the air conditioner to form a first power connection part. It may also include an electric heater body, which is detachably installed inside the air conditioner, and one end of which forms a second power connection part that can be adapted to and connected to the first power connection part.

[0022] Therefore, during installation, the second electrical connection part at one end of the electric heater body and the first electrical connection part of the electrical base are first adapted and connected. Then, the electric heater body is extended through the first side wall into the air conditioner, and the electrical base is installed on the first side wall of the air conditioner through the first mounting structure. Thus, the installation of the electric heater is achieved.

[0023] This electric heater, through its adaptable connection base and heater body structure, allows the heater body to be powered simply by connecting it to the base, forming a wire-free design. By directly connecting the heater body to the base, it achieves the desired power supply effect, thus solving the problem of incompatibility caused by different length requirements for the power connection wires of the same model of electric heater body on different specifications of air conditioning units.

[0024] During disassembly, simply disconnect the power base from the first side wall to pull the electric heater out of the air conditioner. This makes disassembly and assembly convenient and saves time. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] To address the technical problem that the same electric heater cannot be universally compatible with different generating units due to the different lead lengths required for different units, this application provides an electric heater that can achieve leadless operation and is adaptable to different generating units.

[0039] Currently, the electric heater inside air conditioners on the market is generally a structure with a power lead wire for the heater. When disassembling, installing, or replacing the electric heater, it is necessary to first remove the indoor unit casing of the air conditioner, then disconnect the power connection wire, and only then can the electric heater be disassembled. This undoubtedly makes the operation steps cumbersome and wastes time.

[0040] Furthermore, during installation, the same model of electric heater may require different power cord lengths when assembled with different air conditioning units due to differences in their internal structure and circuit layout. This necessitates adjustments to the power cord during assembly, making it impossible for the same model of electric heater to be compatible with different air conditioning units.

[0041] Figure 1 An electric heater is provided as an embodiment of this application. The electric heater is installed on an air conditioner 1.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, air conditioner 1 has a first sidewall;

[0043] The electric heater includes:

[0044] The power base 2 is detachably mounted on the first side wall of the air conditioner 1 via the first mounting structure. One end of the power base 2 extends through the first side wall into the interior of the air conditioner 1 and forms the first power receiving part.

[0045] The electric heater body 3 is detachably installed inside the air conditioner 1, and one end of the electric heater body 3 forms a second electrical connection that is adapted and connected to the first electrical connection.

[0046] Therefore, by setting up an electrical base 2 with a first electrical connection part, which works in conjunction with a second electrical connection part at one end of the electric heater body 3, the electric heater body 3 can be plugged in and powered on. The original power connection wire of the electric heater is removed and replaced by the second electrical connection part, thus forming a wireless structure. It can be directly plugged into the first electrical connection part of the electrical base 2 set on the first side wall of the air conditioner 1 to achieve power supply, thus avoiding the problem of incompatibility between electric heater bodies 3 of the same model installed on different air conditioning units.

[0047] Optionally, the first power connection part can be in the form of a socket, and the second power connection part can be in the form of a plug.

[0048] like Figure 3 As shown, a through hole 4 communicating with the interior of the air conditioner is provided on the first side wall, and the first electrical contact part extends through the through hole 4 into the interior of the air conditioner 1.

[0049] The first mounting structure includes:

[0050] The first mounting hole 5 has at least two holes, both of which are located on the first sidewall and are symmetrically distributed on both sides of the through hole 4.

[0051] The second mounting hole has at least two holes, and each hole is located at the end of the power base away from the first power receiving part, and the at least two second mounting holes correspond one-to-one with the at least two first mounting holes;

[0052] Mounting component 6, which passes through the second mounting hole and the first mounting hole 5 in sequence, mounts the power base 2 onto the first side wall; optionally, the type of mounting component 6 is a screw.

[0053] Therefore, when installing the power base 2, the first power receiving part at one end of the power base 2 is extended through the through hole 4 into the air conditioner 1, and the other end of the power base 2 is located outside the air conditioner 1, so that the second mounting hole and the first mounting hole 5 correspond to each other. The mounting piece 6 passes through the second mounting hole and the first mounting hole 5 in sequence, and the power base 2 is installed on the first side wall.

[0054] The presence of at least two first mounting holes 5 effectively ensures a secure connection between the power base 2 and the first side wall;

[0055] By adapting and connecting the second electrical contact part and the first electrical contact part at one end of the electric heater body 3, the electric heater body 3 can be powered on.

[0056] Disassembly can be completed simply by pulling the electric heater body 3 directly off the power base 2.

[0057] The air conditioner 1 also has a second side wall opposite to the first side wall, and the end of the electric heater body 3 away from the second power connection part is detachably mounted on the inner wall of the second side wall through the second mounting structure;

[0058] Furthermore, such as Figure 4 As shown, the second mounting structure includes:

[0059] The fastener 7 is fixedly installed on the inner wall of the second side wall. The fastener 7 is provided with a snap-fit ​​part for snapping the end of the electric heater body 3 away from the second electrical contact part.

[0060] The end of the electric heater body 3 away from the second electrical contact part is formed into a pin end, which can cooperate with the snap-fit ​​part to achieve connection;

[0061] It should be noted that the snap-fit ​​part can be a slot or a buckle, which can prevent the electric heater body 3 from shaking after it is installed.

[0062] The end of the power base 2 away from the first power receiving part is located on the outside of the air conditioner 1 and forms a power receiving end;

[0063] The air conditioner 1 is equipped with a power plug, which can be adapted to connect to the power connector for power supply to the power base 2.

[0064] Therefore, by configuring a power supply plug on the air conditioner 1, the power supply plug can be connected to the power terminal of the power base 2, so that the air conditioner 1 can supply power to the electric heater body 3 after it is powered on.

[0065] Optionally, the power connection can be in the form of a socket.

[0066] It should be noted that, as Figure 5 As shown, the electric heater body 3 is located on one side of the evaporator 8 inside the air conditioner 1 and is close to the air outlet of the air conditioner 1. A fan 9 is provided on the side of the evaporator 8 away from the electric heater body 3.

[0067] Therefore, when the indoor temperature is low, by turning on the air conditioner 1, since the power plug is located on the air conditioner 1 and is adapted to connect to the power terminal of the power base 2, and the second power terminal of the electric heater body 3 is adapted to connect to the first power terminal of the power base 2, the power plug can supply power to the power base 2 after the air conditioner 1 is powered on, so the power base 2 supplies power to the electric heater body 3, and the electric heater body 3 is powered on and heated. Through the blowing action of the fan 9, the airflow passing through the electric heater body 3 can be heated, and the heated airflow is blown into the room from the air outlet of the air conditioner 1, which can increase the indoor temperature and achieve the purpose of heating.

[0068] Working principle: During installation, the second electrical connection part of the electric heater body 3 and the first electrical connection part of the electrical base 2 are adapted and connected to ensure a tight connection. Then, the pin end of the electric heater body 3 is inserted into the air conditioner 1 through the through hole 4 and extends to the inner wall of the second side wall, where it is adapted and connected to the snap-fit ​​part. The snap-fit ​​part snaps and limits the pin end of the electric heater body 3 to prevent the electric heater body 3 from shaking, thereby fixing the electric heater body 3 inside the air conditioner 1.

[0069] During this process, the power base 2 can contact the first side wall of the air conditioner 1. At this time, the second mounting hole of the power base 2 corresponds to the first mounting hole 5 on the first side wall of the air conditioner 1. Then, the power base 2 is installed on the first side wall by the mounting piece 6 passing through the second mounting hole and the first mounting hole 5 in sequence. Thus, the installation and fixing of the electric heater body 3 is completed.

[0070] When indoor heating is required, simply connect the power plug on the air conditioner 1 to the power terminal of the power base 2. Since the power cord of the air conditioner 1 is energized, the power connector can naturally supply power to the power base 2, thereby supplying power to the electric heater body 3, causing the electric heater body 3 to be energized and heated.

[0071] When disassembly is required, the power supply to the air conditioner 1 is turned off. The power supply connector is then disconnected from the power terminal of the power base 2. The mounting piece 6 is then removed to disconnect the connection between the first side wall and the power base 2. The power base 2 and the electric heater body 3 can then be directly pulled out from inside the air conditioner 1, allowing for the disassembly of the electric heater body 3 and the power base 2. This facilitates maintenance and replacement of the electric heater body 3. The operation is simple and convenient. Compared with the cumbersome disassembly process of the prior art, the electric heater of this application does not require the removal of the air conditioner indoor unit casing when the electric heater body 3 needs to be disassembled or replaced. This makes the operation convenient, saves time and manpower, and improves work efficiency.

[0072] Meanwhile, the electric heater of this application is designed to replace the original electric heater that requires a power connection wire with a structure in which the electric heater body 3 and the power base 2 can be connected to each other. The electric heater body 3 does not need to be led and is directly powered through the power base 2. This allows it to be compatible with air conditioning units of different specifications. There is no need to worry about the problem of the same model of electric heater being incompatible due to the different requirements of the power connection wire length of different air conditioning units.

[0073] The electric heater proposed in this application has high compatibility. During disassembly and assembly, there is no need to remove the air conditioner cover, evaporator, volute, fan blades and other parts. The electric heater body 3 can be directly disassembled and assembled from the outside of the air conditioner 1. The operation is convenient and quick, saves time and greatly improves the efficiency of after-sales installation and maintenance.

[0074] When the side space of the air conditioner 1 is not sufficient for the disassembly and assembly of the electric heater body 3, the power base 2 can be removed first, then the electric heater body 3 can be pulled out from the snap-fit ​​part, and then the electric heater body 3 can be removed from the air outlet of the air conditioner 1.

[0075] This application also provides an air conditioner, including an electric heater as described in any of the foregoing embodiments.
