Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, and more specifically, relates to a heater with a single motor and dual blowers. Background Technology

[0002] A heater is a heating device that can be widely used for heating in homes, offices, hotels, shopping malls, hospitals, schools, etc. Commonly used heaters are usually ceiling heaters, which are combined units consisting of a fan and a heater.

[0003] Existing ceiling-mounted heaters typically use a combination of a single fan and a single heating element. This results in low heating efficiency from a single fan, small air exchange, and hot air only being discharged from a single heating element. This not only causes uneven temperature distribution but also means that if the heating element malfunctions, the entire heating system will not function properly, affecting the user experience. Taking a novel heater housing disclosed in Chinese invention patent literature (CN202210956681.3) as an example, this invention uses a single fan to drive two heating elements through an Archimedes curve-shaped air duct, making airflow smoother and improving air output or ventilation efficiency. However, this invention simply connects the air duct directly to the heating element. When the airflow moves, it impacts the housing at the heating element, forming eddies that reduce heat exchange efficiency and generate noise.

[0004] Therefore, we need a single-motor dual-blowing heater that is compact, highly efficient in heating, and stable in operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a heater with a single motor and dual blowers, which has a compact structure and optimizes the air flow path by working in coordination with the dual heating devices and the air exchange port, thereby reducing eddies and noise.

[0006] This utility model discloses a single-motor dual-blowing heater, which includes a base and a top cover. The base is detachably equipped with a fan, a control module, a heating device one, and a heating device two. An air vent is provided on the side of the base near the heating device one to regulate indoor air circulation. The heating device one and the heating device two are respectively located on both sides of the fan to ensure that the heat output by the heating device one and the heating device two is evenly distributed.

[0007] The control module is electrically connected to the fan, heating device one, and heating device two, respectively, and is used to control the heater to blow out hot air.

[0008] The top cover is equipped with an air inlet and a pair of air outlets. The air inlet is located in a position corresponding to the fan, and the air outlet is located in a position corresponding to heating device one and heating device two, ensuring that the air inlet and outlet paths are reasonable, reducing airflow interference, and improving heat exchange efficiency.

[0009] The fan is connected to heating device one, heating device two and air exchange port through air blowing channels to form dual hot air output and air circulation, effectively avoiding eddies and noise generated by a single air duct, and improving heating effect and user experience.

[0010] As a further improvement of this utility model, the air blowing channel includes an upper arc plate, a folded plate, a lower arc plate, and a triangular plate, which are detachably installed on the bottom surface of the base. One end of the upper arc plate abuts against the upper side of the heating device one, and the other end surrounds the fan circumferentially, for guiding and transporting the airflow gathered by the fan into the heating device one. The other end of the upper arc plate is smoothly and fixedly connected to one end of the folded plate. The other end of the folded plate and one end of the lower arc plate abut against both sides of the heating device two, for guiding and transporting the airflow gathered by the fan into the heating device two. The other end of the lower arc plate is fixedly connected to the middle of the lower inner side wall of the base. The triangular plate is located between the heating device one and the air exchange port, so that the fan can transport the airflow to the heating device one and the air exchange port respectively.

[0011] As a further improvement of this utility model, the lower arc plate is arranged parallel to the folding plate at a section near the second heating device to form a flow channel for the fan to deliver the air to the second heating device. The arc-shaped flow channel design effectively guides the airflow, reduces energy loss, and improves thermal efficiency.

[0012] As a further improvement of this utility model, the triangular plate includes a long inclined plate, a short arc plate and a DC plate that are fixedly connected in sequence. The DC plate is parallel to the lower side wall of the base. The short arc plate surrounds the fan circumferentially and is used to separate the area entering the heating device from the area of ​​the air exchange port. The long inclined plate and the upper arc plate are arranged parallel to each other near the section of the heating device to form a flow channel for the fan to deliver to the heating device. The arc-shaped flow channel design effectively guides the airflow, reduces energy loss and improves thermal efficiency.

[0013] As a further improvement of this utility model, a through hole is opened at the bottom of the upper arc plate for connecting the fan and the control module with wires, so as to avoid the wires from getting tangled and ensure the stability of the equipment.

[0014] As a further improvement of this utility model, a wire groove is opened on the top of the side wall near the upper arc plate of the base for connecting the heating device and the control module with wires, so as to avoid the wires being exposed and affecting the safety of use.

[0015] As a further improvement of this utility model, the heating device includes a PTC heating element and a guide plate. The guide plate is located between the long inclined plate and the upper arc plate, and is arranged in an arc shape from bottom to top along the length of the device seat. It is used to guide the air through the PTC heating element for heating, avoid friction between the air and the inner wall of the device seat, and achieve the effect of stabilizing the flow and reducing noise.

[0016] As a further improvement of this utility model, a guide structure is provided between the heating device and the air exchange port. The guide structure is located on the side of the guide plate and is arranged in an arc shape from bottom to top along the width direction of the base. It is smoothly connected to the guide plate inside the heating device and is used to transport the airflow entering the heating device along the guide plate to the PTC heating element and guide the airflow entering the air exchange port. The heating efficiency and air exchange effect are improved by optimizing the airflow path.

[0017] As a further improvement of this utility model, an air guide structure II is provided on the inner side of the air exchange port. It is arranged in an arc shape from top to bottom along the length of the base and is fixedly connected to the side wall of the lower part of the base. It is used to guide the airflow gathered by the fan to the air exchange port along the air guide structure II to achieve efficient air exchange and ensure indoor air circulation.

[0018] Compared to existing technologies, the advantages of this utility model are as follows: This utility model's single-motor dual-blowing heater optimizes airflow path and improves overall thermal and ventilation efficiency by coordinating a single fan with dual heating devices and an air vent, effectively reducing energy consumption. The use of arc-shaped channels to deliver airflow to heating device one and heating device two respectively improves heating efficiency. The installation of wires for the control module, electrically connected to heating device one and the fan, via through holes at the bottom of the upper arc plate and wire grooves on the top of the mounting base wall reduces wire tangling and optimizes assembly and maintenance. The optimization of the airflow path by the first air guide structure ensures stable airflow and ventilation, thereby improving heating efficiency and ventilation. The further guidance of the second air guide structure at the air vent ensures more efficient indoor air circulation and reduces eddies and noise. Attached Figure Description

[0026] Specific Implementation Example 1: Please refer to Figures 1-5 A single-motor dual-blowing heater includes a base 1, a top cover 2, and a fan 3, a control module 4, a heating device 1 5, and a heating device 2 6 that are detachably installed inside the base 1. The base 1 has an air vent 11 on the side near the heating device 1 5 to regulate indoor air circulation. The heating device 1 5 and the heating device 2 6 are respectively located on both sides of the fan 3 to ensure that the heat output by the heating device 1 5 and the heating device 2 6 is evenly distributed.

[0027] The control module 4 is electrically connected to the fan 3, heating device 5 and heating device 6 respectively, and is used to control the heater to blow out hot air.

[0028] like Figure 2 The top cover 2 shown is provided with an air inlet 21 and a pair of air outlets 22. The position of the air inlet 21 corresponds to the fan 3, and the position of the air outlet 22 corresponds to the heating device 5 and the heating device 6, so as to ensure that the air inlet and outlet paths are reasonable, reduce airflow interference, and improve heat exchange efficiency.

[0029] like Figure 3 The fan 3 shown is connected to the heating device 5, the heating device 6 and the air exchange port 11 through the air blowing channel 7, forming a dual-path hot air output and air circulation, which effectively avoids the eddies and noise generated by a single air duct, and improves the heating effect and user experience.

[0030] Specifically, the air blowing channel 7 includes an upper arc plate 71, a folding plate 72, a lower arc plate 73, and a triangular plate 74, which are detachably installed on the bottom surface of the base. One end of the upper arc plate 71 abuts against the upper side of the heating device 5, and the other end surrounds the fan 3 circumferentially, for guiding and delivering the airflow gathered by the fan 3 into the interior of the heating device 5. The other end of the upper arc plate 71 is smoothly and fixedly connected to one end of the folding plate 72. The other end of the folding plate 72 and one end of the lower arc plate 73 abut against both sides of the heating device 6, for guiding and delivering the airflow gathered by the fan 3 into the interior of the heating device 6. The other end of the lower arc plate 73 is fixedly connected to the middle of the lower inner side wall of the base 1. The triangular plate 74 is located between the heating device 5 and the air exchange port 11, so that the fan 3 delivers the airflow to the heating device 5 and the air exchange port 11 respectively, realizing the functions of outputting hot air and air exchange.

[0031] Specifically, the lower arc plate 73 is arranged parallel to the folding plate 72 near the heating device 2 6, forming a flow channel for the fan 3 to deliver air to the heating device 2 6. The arc-shaped flow channel design effectively guides the airflow, reduces energy loss, and improves thermal efficiency.

[0032] Specifically, the triangular plate 74 includes a long inclined plate 741, a short arc plate 742, and a direct current plate 743 that are fixedly connected in sequence. The direct current plate 743 is parallel to the lower side wall of the base 1 and is used to transport airflow in the area of ​​the ventilation port 11. The short arc plate 742 surrounds the fan 3 around the perimeter and is used to separate the area entering the heating device 5 from the area of ​​the ventilation port 11. The long inclined plate 741 and the section of the upper arc plate 71 near the heating device 5 are arranged parallel to each other and are used to form the flow channel from the fan 3 to the heating device 5. The arc-shaped flow channel design effectively guides the airflow, reduces energy loss, and improves thermal efficiency.

[0033] Specifically, such as Figure 4 The bottom of the upper arc plate 71 shown has a through hole for connecting the fan 3 and the control module 4 with wires, so as to avoid the wires from getting tangled and ensure the stability of the equipment.

[0034] Specifically, a wire groove 12 is provided on the top of the side wall of the base 1 near the upper arc plate 71 for connecting the heating device 5 and the control module 4 with wires, so as to avoid the wires being exposed and affecting the safety of use.

[0035] Specifically, such as Figure 5 The heating device 5 shown includes a PTC heating element 51 and a guide plate 52. The guide plate 52 is located between the long inclined plate 741 and the upper arc plate 71, and is arranged in an arc shape from bottom to top along the length of the base 1. It is used to guide the air through the PTC heating element 51 for heating, avoid friction between the air and the inner wall of the base 1, and achieve the effect of stabilizing the flow and reducing noise.

[0036] Specifically, a guide structure 8 is provided between the heating device 5 and the air exchange port 11. The guide structure 8 is located on the side of the guide plate 52 and is arranged in an arc shape from bottom to top along the width direction of the base 1. It is smoothly connected to the guide plate 52 inside the heating device 5. It is used to transport the airflow entering the heating device 5 along the guide plate 52 to the PTC heating element 51 along the guide structure 8 and guide the airflow into the air exchange port 11. By optimizing the airflow path, the heating efficiency and ventilation effect are improved.

[0037] Specifically, an air guide structure 2 9 is provided on the inner side of the air exchange port 11. It is arranged in an arc shape from top to bottom along the length of the base 1. The two ends of the air guide structure 2 9 are fixedly connected to the side wall of the lower part of the base 1 and the DC plate 743 of the triangular plate 74, respectively. It is used to guide the airflow gathered by the fan 3 to the air exchange port 11 along the air guide structure 2 9 to achieve efficient air exchange and ensure indoor air circulation.

[0038] During use, the heater is installed in the work area. The control module 4 activates the fan 3, heating device 5, and heating device 6, enabling a single fan 3 to provide dual-outlet heating and ventilation. After the fan 3 is turned on, airflow is drawn in through the air inlet 21. The airflow near the heating device 5 is guided by the arc-shaped flow channel between the long inclined plate 741 and the upper arc plate 71 to the guide plate 52 at the bottom of the PTC heating element 51. The airflow is then guided by the guide plate 52 and the air guide structure 8, and delivered to the PTC heating element 51 for uniform heating before being output from the air outlet 21. The airflow on the side of fan 3 near heating device 2 6 is guided into the interior of heating device 2 6 by the arc flow channel between the lower arc plate 73 near heating device 2 6 and the folding plate 72. After being uniformly heated, the airflow is output at the air outlet 22. The airflow on the side of fan 3 near the air exchange port 11 is guided to the air exchange port 11 by air guide structure 1 8 and air guide structure 2 9, achieving efficient air exchange and ensuring indoor air circulation. Through optimized design, the equipment has low noise and low energy consumption during operation, significantly improving the user experience and extending the service life of the equipment, achieving multiple goals of high efficiency, energy saving and environmental protection.
