Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a heater structure and a hot and cold switching heater. Background Technology

[0002] Currently, many home heaters on the market offer both heating and cooling modes. However, in the hot summer, when the cooling mode is activated, the airflow and speed become very low because the internal heating element blocks the heater's airflow, thus failing to meet users' needs for year-round use. To address this, Chinese utility model patent CN216244675U (hereinafter referred to as Document 1) discloses a heating component and a heating / cooling fan using this component. By rotating the rotating bracket 2, the heating element 1 can either block or detach from the air outlet 13. When the heating element 1 blocks the air outlet 13, it operates in heating mode; when it detaches, it operates in cooling mode. This ensures that the heating element 1 does not block the air outlet 13 in cooling mode, improving the airflow effect.

[0003] However, the solution in Document 1 still has the following shortcomings: Since the air duct guide plate 7 also needs to switch between swinging and resetting (see paragraph

[0036] of the instruction manual in Document 1) to adapt to the two working modes of cold air and warm air respectively, the air duct guide plate 7 needs to rely on the reset torsion spring 8 to achieve the switching between the two modes. However, the torsion spring will gradually fatigue and wear out during frequent use until it loses its elasticity, resulting in a weakening of its reset effect. This makes it impossible for the air duct guide plate 7 to effectively fit against the inner wall of the air outlet or stay in the predetermined position, thereby affecting the blowing effect. In addition, the installation is difficult, it is easily damaged, the manufacturing cost is high, and it is not easy to maintain. Utility Model Content

[0004] The purpose of this utility model is to provide a heating structure and a hot and cold switching heater to address the shortcomings of the existing technology, aiming to solve the adverse effects caused by the return torsion spring.

[0005] This utility model achieves the above objectives through the following technical solution: a warm air structure, comprising:

[0006] Switch the motor;

[0007] The heating element assembly has a rotating part at one end that is connected to the switching motor;

[0008] The connector is provided with a guide groove; and

[0009] The oscillating blade is provided with a first connecting shaft hinged to the rotating part and a second connecting shaft inserted into the guide groove.

[0010] As a further embodiment of this invention: the rotating part is provided with a first connecting shaft end connected to the rotating shaft of the switching motor, and a second connecting shaft end hinged to the first connecting shaft. Specifically, the switching between the two states of the oscillating blade can be achieved without a return torsion spring, the switching effect is reliable and not easily damaged, the installation difficulty is low, the cost is low and it is easy to maintain, effectively solving the adverse effects caused by the return torsion spring in the prior art.

[0011] As a further improvement of this invention, the oscillating blade is also provided with a limiting part for rotating the oscillating blade to a predetermined angle. Specifically, this allows the oscillating blade to rotate to a predetermined angle in the cold air operating mode, preventing the oscillating blade from rotating too much and affecting the air guiding effect of the cold air outlet. Furthermore, this achieves the switching between two states of the oscillating blade without the need for a return torsion spring. The switching effect is reliable and not easily damaged, the installation is simple, the cost is low, and it is easy to maintain, effectively solving the adverse effects of the return torsion spring in the prior art.

[0012] As a further embodiment of this utility model: the heating element assembly includes a rotating frame and a heating element mounted on the rotating frame, with the rotating part located at one end of the rotating frame;

[0013] A limiting part is located on the first connecting shaft, and an abutment position is provided on the rotating frame where the limiting part abuts. Specifically, the limiting part abuts against the abutment position on the rotating frame, thereby limiting the maximum angle or predetermined angle of the swing blades to achieve the best air guiding effect of the swing blades at the air outlet. Furthermore, it enables the switching between two states of the swing blades without the need for a return torsion spring, with reliable switching performance that is not easily damaged, low installation difficulty, low cost, and easy maintenance, effectively solving the adverse effects of the return torsion spring in the prior art.

[0014] As a further aspect of this invention, the guide groove is an oblong groove. When the heating element assembly swings or rotates, the second connecting shaft of the swing blade moves along the guide groove of the connecting seat. When the second connecting shaft moves to either end of the guide groove, if the heating element assembly continues to move, the swing blade will rotate relative to the heating element assembly around the first connecting shaft, enabling the swing blade to switch between swinging and resetting. This allows the swing blade to adapt to both cold and warm air operating modes. Furthermore, this achieves the switching between two states of the swing blade without the need for a reset torsion spring. The switching effect is reliable and not easily damaged, the installation is simple, the cost is low, and it is easy to maintain, effectively solving the adverse effects of the reset torsion spring in the prior art.

[0015] As a further embodiment of this utility model: the connecting seat is provided with a motor accommodating cavity, and the switching motor is installed in the motor accommodating cavity.

[0016] As a further embodiment of this utility model: the bottom of the heating element assembly is provided with a wire management plate, and the wire management plate is provided with a wire management groove.

[0017] As another embodiment of this utility model: a hot and cold switching type heater, comprising:

[0018] The casing is equipped with an air outlet;

[0019] The wind turbine component is installed inside the housing;

[0020] Wind turbine motor drives the wind turbine components to rotate; and

[0021] The heating structure, mounted on the housing, is any of the heating structures described above, wherein the switching motor is used to drive the heating element assembly into and / or out of the air outlet.

[0022] As a further embodiment of this utility model: a short air guide wall and a long air guide wall are respectively provided on the outer sides of the air outlet, and a storage position is also provided on the housing adjacent to the side of the short air guide wall. The switching motor is used to drive the heating element assembly to move between the air outlet and the storage position.

[0023] As a further embodiment of this utility model: the oscillating blade is disposed on the side of the heating element assembly near the air guide wall, and the oscillating blade has an abutment surface and an air guide surface.

[0024] The beneficial effects of this utility model are:

[0025] This solution uses a switching motor to drive the heating element assembly to rotate, allowing it to swing at a certain angle. This enables the heating element assembly to enter or leave the air outlet, switching between the warm air and cold air operating modes of the heater. This avoids the heating element assembly blocking the air outlet and affecting the cold air output. When the heating element assembly swings or rotates, the second connecting shaft of the swing blade moves along the guide groove of the connecting seat. When the second connecting shaft moves to either end of the guide groove, if the heating element assembly continues to move, the swing blade will rotate relative to the heating element assembly around the first connecting shaft, switching between swinging and resetting. This allows the swing blade to adapt to both cold and warm air operating modes. This solution eliminates the need for a reset torsion spring to achieve the two states of the swing blade. The switching effect is reliable and not easily damaged. It is easy to install, low-cost, and easy to maintain, effectively solving the adverse effects of existing technologies that rely on reset torsion springs.

[0026] In the warm air working mode, the heating element assembly enters and seals the air outlet, so that the air generated by the fan wheel passes through the heating element assembly and blows out warm air. In order to avoid air leakage at the air outlet without passing through the heating element assembly and thus affecting the blowing effect of the warm air, the two sides of the swing blade need to fit against the air guide wall of the air outlet and the side wall of the heating element assembly. This is to prevent cold air leakage due to gaps on both sides of the swing blade. At this time, the second connecting shaft is located at one end of the guide groove.

[0027] In cold air operation mode, the heating element assembly rotates away from the air outlet until it enters the storage position of the housing. During this process, the second connecting shaft of the oscillating blade moves from one end of the guide groove to the other end. The heating element assembly continues to rotate. Since the second connecting shaft is limited by the other end of the guide groove, the oscillating blade will rotate around the first connecting shaft as the rotation axis, causing the oscillating blade and the heating element assembly to rotate relative to each other until the limiting part of the oscillating blade abuts against the abutting part of the heating element assembly. This allows the oscillating blade to combine with the air guide wall of the air outlet to form an air guide. When the heating element assembly does not block the cold air blowing, it can also make the cold air blow farther and more powerfully, thereby further improving the cold air blowing effect. At the same time, it makes the overall structure more compact and saves space. Attached Figure Description

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0055] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The terminology used in this specification is only for the purpose of describing specific embodiments and is not intended to limit the invention.

[0056] like Figures 1-10 As shown in the figure, a warm air structure is provided in this embodiment of the utility model, including: a switching motor 1, a heating element assembly 2, a connecting base 3, and a swing blade 4. Wherein:

[0057] Switch to motor 1;

[0058] The heating element assembly 2 has a rotating part 211 at one end that is connected to the switching motor 1;

[0059] Connector 3 is provided with guide groove 31;

[0060] The oscillating blade 4 is provided with a first connecting shaft 41 hinged to the rotating part 211 and a second connecting shaft 42 inserted into the guide groove 31. Specifically, the oscillating blade 4 is a guide vane or a guide plate.

[0061] This solution uses a switching motor 1 to drive the heating element assembly 2 to rotate, allowing it to swing at a certain angle. This enables the heating element assembly 2 to enter or leave the air outlet 51, switching between the warm air and cold air operating modes of the heater. This avoids the heating element assembly 2 blocking the air outlet 51 and affecting the cold air output. When the heating element assembly 2 swings or rotates, the second connecting shaft 42 of the swing blade 4 moves along the guide groove 31 of the connecting seat 3. When the second connecting shaft 42 moves to either end of the guide groove 31, if the heating element assembly 2 continues to move, the swing blade 4 will rotate relative to the heating element assembly 2 around the first connecting shaft 41, allowing the swing blade 4 to switch between swinging and resetting. This allows the swing blade 4 to adapt to both cold and warm air operating modes. This solution achieves the switching between the two states of the swing blade 4 without the need for a reset torsion spring. The switching effect is reliable and not easily damaged. It is easy to install, low-cost, and easy to maintain, effectively solving the adverse effects of the reset torsion spring in existing technologies.

[0062] In the warm air working mode, the heating element assembly 2 enters and seals the air outlet 51, so that the air generated by the fan wheel 6 passes through the heating element assembly 2 and blows out warm air. In order to avoid air leakage at the air outlet 51 without passing through the heating element assembly 2 and thus affecting the blowing effect of the warm air, the two sides of the swing blade 4 need to fit against the air guide wall 512 of the air outlet 51 and the side wall of the heating element assembly 2 to avoid cold air leakage due to gaps on both sides of the swing blade 4. At this time, the second connecting shaft 42 is located at one end of the guide groove 31.

[0063] In cold air operation mode, the heating element assembly 2 rotates away from the air outlet 51 until it enters the storage position 52 of the housing 5. During this process, the second connecting shaft 42 of the oscillating blade 4 moves from one end of the guide groove 31 to the other end. The heating element assembly 2 continues to rotate. Since the second connecting shaft 42 is limited by the other end of the guide groove 31, the oscillating blade 4 will rotate around the first connecting shaft 41 as the rotation axis, so that the oscillating blade 4 and the heating element assembly 2 rotate relative to each other until the limiting part 43 of the oscillating blade 4 abuts against the abutting position 212 of the heating element assembly 2, so that the oscillating blade 4 can combine with the air guide wall 512 of the air outlet 51 to form an air guide. When the heating element assembly 2 does not block the cold air blowing, it can also make the cold air blow farther and more powerfully, so as to further improve the cold air blowing effect, while making the overall structure more compact and saving space.

[0064] In one embodiment, such as Figure 1 As shown, the rotating part 211 has a first connecting end 2111 connected to the rotating shaft of the switching motor 1, and a second connecting end 2112 hinged to the first connecting shaft 41. Specifically, the switching between the two states of the oscillating blade 4 can be achieved without a reset torsion spring. The switching effect is reliable and not easily damaged. The installation is simple, the cost is low, and it is easy to maintain, effectively solving the adverse effects caused by the reset torsion spring in the prior art.

[0065] In another embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figures 8-10 As shown, the oscillating blade 4 is also provided with a limiting part 43 for rotating the oscillating blade 4 to a predetermined angle. Specifically, this allows the oscillating blade 4 to rotate to a predetermined angle in the cold air working mode, preventing the oscillating blade 4 from rotating too much and affecting the air guiding effect of the cold air outlet. Furthermore, it enables the oscillating blade 4 to switch between two states without the need for a return torsion spring. The switching effect is reliable and not easily damaged, the installation is simple, the cost is low, and it is easy to maintain, effectively solving the adverse effects caused by the return torsion spring in the prior art.

[0066] In yet another embodiment, such as Figure 2 and Figure 4 As shown, the heating element assembly 2 includes a rotating frame 21 and a heating element 22 mounted on the rotating frame 21, with a rotating part 211 located at one end of the rotating frame 21;

[0067] A limiting part 43 is provided on the first connecting shaft 41, and an abutment position 212 is provided on the rotating frame 21 against which the limiting part 43 abuts. Specifically, the limiting part 43 abuts against the abutment position 212 on the rotating frame 21, thereby limiting the maximum angle or predetermined angle of the swing blade 4 to achieve the best air guiding effect of the swing blade 4 at the air outlet 51. Furthermore, it enables the swing blade 4 to switch between two states without the need for a return torsion spring, with reliable switching effect and low installation difficulty, low cost and easy maintenance, effectively solving the adverse effects caused by the return torsion spring in the prior art.

[0068] In yet another embodiment, such as Figures 1-10 As shown, the guide groove 31 is an oblong groove. When the heating element assembly 2 swings or rotates, the second connecting shaft 42 of the swing blade 4 moves along the guide groove 31 of the connecting seat 3. When the second connecting shaft 42 moves to either end of the guide groove 31, if the heating element assembly 2 continues to move, the swing blade 4 will rotate relative to the heating element assembly 2 with the first connecting shaft 41 as the pivot, enabling the swing blade 4 to switch between swinging and resetting, thus allowing the swing blade 4 to adapt to both cold and warm air working modes. Furthermore, it achieves the switching between two states of the swing blade 4 without the need for a reset torsion spring, with a reliable switching effect that is not easily damaged, low installation difficulty, low cost, and easy maintenance, effectively solving the adverse effects caused by the reset torsion spring in the prior art.

[0069] In another embodiment, such as Figures 3-5As shown, the connecting seat 3 is provided with a motor housing cavity, and the switching motor 1 is installed in the motor housing cavity 32. Specifically, this further improves the compactness of the overall structure and reduces the space occupied. Furthermore, it enables the switching of the swing blade 4 to two states without the need for a return torsion spring. The switching effect is reliable and not easily damaged, the installation is simple, the cost is low and it is easy to maintain, effectively solving the adverse effects of the return torsion spring in the prior art.

[0070] In another embodiment, such as Figure 4 As shown, the bottom of the heating element assembly 2 is provided with a cable management plate 23, and the cable management plate 23 is provided with a cable management groove 231. Specifically, it can better organize the cables, avoid the interference of the rotation of the heating element assembly 2 due to the messy cables, and also avoid the risk of the cables getting tangled due to the rotation of the heating element assembly 2, reducing safety hazards, and further improving the compactness of the overall structure and reducing the space occupied. Furthermore, it can achieve the switching between two states of the swing blade 4 without the need for a reset torsion spring. The switching effect is reliable and not easily damaged, the installation difficulty is low, the cost is low and the maintenance is easy, effectively solving the adverse effects of the reset torsion spring in the prior art.

[0071] A type of hot and cold switching heater, such as Figures 6-10 As shown, it includes: housing 5, impeller 6, impeller motor 7, and heating structure. Among them:

[0072] The housing 5 is provided with an air outlet 51;

[0073] Wind turbine component 6 is installed inside housing 5;

[0074] The wind turbine motor 7 drives the wind turbine component 6 to rotate;

[0075] The heating structure, mounted on the housing 5, is any of the heating structures described above. The switching motor 1 drives the heating element assembly 2 to enter and / or leave the air outlet 51. In this design, the switching motor 1 drives the heating element assembly 2 to rotate, allowing it to swing at a certain angle. This enables the heating element assembly 2 to enter or leave the air outlet 51, switching between the heating and cold air modes of the heater, thus preventing the heating element assembly 2 from blocking the air outlet 51 and affecting the cold air output. When the heating element assembly 2 swings or rotates, the second connecting shaft 42 of the swing blade 4 moves along the guide groove 31 of the connecting seat 3. When the second connecting shaft 42 moves to either end of the guide groove 31, if the heating element assembly 2 continues to move, the swing blade 4 will rotate relative to the heating element assembly 2 around the first connecting shaft 41, allowing the swing blade 4 to switch between swinging and resetting, thus enabling the swing blade 4 to adapt to both cold and warm air modes. This solution eliminates the need for a reset torsion spring to achieve the switching between the two states of the oscillating blade 4. The switching effect is reliable and not easily damaged. It is easy to install, low-cost, and easy to maintain, effectively solving the adverse effects of the reset torsion spring in the existing technology.

[0076] In another embodiment, such as Figure 2 , Figures 8-10 As shown, the air outlet 51 has a short guide wall 511 and a long guide wall 512 on its outer sides, respectively. The housing 5 also has a storage position 52 adjacent to the short guide wall 511. The switching motor 1 is used to drive the heating element assembly 2 to move between the air outlet 51 and the storage position 52. This allows the oscillating blade 4 to switch between two states without the need for a reset torsion spring. The switching effect is reliable and not easily damaged, the installation is simple, the cost is low, and it is easy to maintain, effectively solving the adverse effects of the reset torsion spring in the prior art.

[0077] Another embodiment, such as Figure 2 , Figure 9 and Figure 10 As shown, the oscillating blade 4 is located on the side of the heating element assembly 2 near the air guide wall 512, and the oscillating blade 4 has a contact surface 44 and an air guide surface 45. Specifically, the contact surface 44 and the air guide surface 45 of the oscillating blade 4 form a certain angle or arc to further improve the air guiding effect in cold air conditions.

[0078] In detail, because the heating element needs to completely cover the air outlet 51 in the warm air mode, to avoid affecting the warm air output effect due to air leakage from the oscillating blade 4, the oscillating blade 4 needs to be in close contact with the side wall of the air guide wall 512 and the rotating frame 21 in the warm air mode. The solution in Reference 1 uses a return torsion spring. After prolonged use, the torsion spring will fatigue and eventually lose its elasticity. After the torsion spring is damaged, in the warm air mode, the oscillating blade 4 will inevitably fail to effectively contact the side wall of the air guide wall 512 and the rotating frame 21. In the cold air mode, the oscillating blade 4 will also fail to swing and stay at the predetermined angle, causing the oscillating blade 4 to fail to form the optimal cold air guide with the air guide wall 512, which will inevitably affect the cold air output effect and prevent the cold air from blowing further. The solution of this application can effectively avoid the adverse effects caused by the damage to the torsion spring.

[0079] In the warm air mode, the heating element assembly 2 enters and blocks the air outlet 51, and the two sides of the swing blade 4 are respectively attached to the air guide wall 512 and the side wall of the rotating frame 21 near the air guide wall 512 to prevent the air outlet 51 from leaking and affecting the warm air blowing effect.

[0080] In cold air mode, the heating element assembly 2 leaves the air outlet 51 and enters the storage position 52 on the housing 5. During this process, the oscillating blade 4 rotates at a certain angle until the limiting part 43 of the oscillating blade 4 abuts against the abutting position 212 on the rotating frame 21. At this time, the side of the oscillating blade 4 near the air guide wall 512 will be almost flush with the air guide wall 512, so that the oscillating blade 4 and the air guide wall 512 can play a better air guiding role at the air outlet 51, allowing the cold air to be blown further and achieving the best cold air blowing effect. In detail, in cold air mode, one side of the contact surface 44 of the oscillating blade 4 is close to or abuts against the air guide short wall 511, and the air guiding surface 45 of the oscillating blade 4 is almost flush with the air guide long wall 512, so that the oscillating blade 4 and the air guide long wall 512 can play a better air guiding role at the air outlet 51.

[0081] In the specification and claims of this application, the terms "comprising / including" and "having / including" and variations thereof are used to specify the presence of the stated features, values, steps or components, but do not exclude the presence or addition of one or more other features, values, steps, components or combinations thereof.

Conversely, some features of the present invention are described only in a single embodiment for brevity; however, these features may also be described individually or in any suitable combination in different embodiments.
