Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a heater. Background Art

[0002] As an indispensable electrical device in modern families and work environments, the core mission of heaters is to efficiently transfer heat energy to indoor spaces by heating the air, creating a warm and comfortable living environment for people.

[0003] Heaters need to ensure that heat can be quickly and stably transferred to the indoor environment through efficient and uniform heating. Traditional heaters usually use a motor to drive the wind wheel to rotate to generate wind flow, and heat the cold air into hot air through the heating component. This method can effectively improve the heating efficiency, so that the indoor temperature can be significantly increased in a short time.

[0004] Although the above method can quickly increase the indoor temperature, as the temperature of the heating component increases, the demand for wind speed also increases accordingly to ensure that the heat can be more effectively distributed to the surrounding space. In order to achieve higher wind speed, heaters usually use the method of increasing the motor speed. However, this method faces serious problems in practical applications.

[0005] When the motor runs at high speed, it will generate a lot of heat. At the same time, due to the heat conduction of the heat generating components, the working environment temperature of the motor will further increase. Especially under high load operation, the superposition effect of this heat will cause the motor temperature to rise rapidly, which will have an adverse effect on its working efficiency and life. In addition, excessive temperature may also cause damage to the internal components of the motor, leading to equipment failure, safety hazards, and even fire. Utility Model Content

[0006] One of the primary purposes of the present invention is to provide a heater to solve at least one of the above problems.

[0007] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0008] A heater is provided to meet one of the purposes of the utility model, including a shell and a wind wheel, a volute and a volute installed in the shell, the volute is provided with an air guide channel, the wind wheel is installed in the air guide channel, the volute tongue is pivotally arranged in the air guide channel, the volute and the volute tongue are also connected by a thermal deformation part, and the thermal deformation part controls the deflection of the volute tongue relative to the volute according to the thermal expansion and contraction characteristics to change the opening size of the air guide outlet of the air guide channel.

[0009] Furthermore, the thermal deformation member is made of a thermal expansion material.

[0010] Furthermore, the volute tongue cooperates with the volute to enclose an air guide outlet of the air guide channel.

[0011] In one embodiment, the thermal deformation member is provided with a first end, the volute tongue is provided with an avoidance gap corresponding to the first end, and the first end is connected to the volute tongue in the avoidance gap.

[0012] Specifically, one of the avoidance gap and the first end is provided with a plug-in shaft, and the other is provided with a plug-in hole, and the plug-in shaft is plugged into the plug-in hole.

[0013] In one embodiment, the volute includes a pair of end covers and an air guide plate arranged between the pair of end covers, the air guide plate is connected to the pair of end covers, the air guide plate is arranged opposite to the volute tongue, and the pair of end covers, the air guide plate and the volute tongue are surrounded to form the air guide outlet.

[0014] Specifically, the thermal deformation member is mounted on the end cover, and the second end of the thermal deformation member is connected to the end cover and / or the wind guide plate of the volute.

[0015] In one embodiment, the heater is provided with a pair of thermal deformation parts, which are respectively arranged on the pair of end covers, and the pair of thermal deformation parts are respectively connected to the volute and the volute tongue.

[0016] In one embodiment, the two ends of the volute tongue are respectively connected to the pair of end covers, and the end covers are further provided with limiting protrusions, and the limiting protrusions are arranged on the deflection path of the volute tongue.

[0017] Furthermore, the heater also includes a control unit, a motor and a heating component. The output shaft of the motor is plugged into the wind wheel, and the control unit is electrically connected to the motor and the heating component respectively. A mounting frame is also provided in the shell, and a heating channel is provided in the mounting frame. The heating channel is arranged in connection with the air guide channel, and the heating component is arranged in the heating channel.

[0018] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0019] First of all, the heater of the utility model realizes sensitive perception of the temperature change inside the heater through the thermal deformation part. According to the characteristics of thermal expansion and contraction, the thermal deformation part can sense the temperature change inside the heater in real time, and automatically adjust the opening size of the air outlet according to this change. This intelligent perception and adaptive adjustment mechanism enables the heater to maintain the best working state under different ambient temperatures and usage conditions. As the thermal deformation part deforms, the swing angle of the volute tongue relative to the volute will change, thereby directly changing the opening size of the air outlet of the air guide channel, cleverly linking the temperature change with the opening size of the air outlet, and realizing precise control of the hot air outlet. When the temperature of the heater is high, the hot air outlet is expanded by expanding the opening size of the air outlet; when the temperature is moderate or low, the opening size of the air outlet is reduced to ensure the heating effect.

[0020] Secondly, the thermal deformation parts work based on the physical properties of thermal expansion and contraction, which is very stable and reliable. Compared with mechanical control or electronic control, thermal deformation parts are not affected by wear or failure of electronic components. Therefore, even during long-term use, thermal deformation parts can maintain their original performance and ensure the stable operation of the heater. Since the working principle of thermal deformation parts is simple and stable, the heater does not require frequent maintenance and replacement of parts. This not only reduces the user's maintenance costs, but also reduces the risk of equipment failure caused by improper maintenance.

[0021] Thirdly, the thermal deformation parts enable the heater to adapt to use in various environmental conditions. Whether it is cold winter or warm early spring, the heater can automatically adjust the hot air output according to the changes in ambient temperature to ensure comfortable and stable indoor temperature. By accurately controlling the hot air output, the heater can reduce unnecessary energy waste while ensuring the heating effect. This not only meets the requirements of modern society for environmental protection and energy saving, but also saves energy costs for users. After long-term use, the energy-saving and emission-reduction effect of the heater will be more significant.

[0022] In addition, when the temperature inside the heater is too high, by expanding the opening size of the air outlet and increasing the hot air output, the load on the motor can be effectively reduced to prevent the motor from overheating and being damaged. This protection mechanism not only extends the service life of the motor, but also improves the overall safety performance of the heater. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The utility model provides a heater, wherein a volute and a volute tongue of the heater are connected via a thermal deformation member, and the thermal deformation member controls the deflection of the volute tongue relative to the volute according to the thermal expansion and contraction characteristics, so as to control the air output of the wind wheel.

[0035] In a typical embodiment of the present invention, Figures 1 to 4 The heater 100 includes a shell 110, a wind wheel 120, a heating component 130, a motor 140, a volute 150, a volute 160, a mounting bracket 170 and a control unit (not shown). The wind wheel 120, the heating component 130, the motor 140, the volute 160, the volute 150 and the mounting bracket 170 are arranged in the shell 110, and the control unit is electrically connected to the heating component 130 and the motor 140 respectively.

[0036] Specifically, the housing 110 has an air duct formed therein. Figure 1 and Figure 2 The air duct includes an air inlet 111 and an air outlet 112 opened on the housing 110. Figure 4 and Figure 5 The volute 160 is provided with an air guide channel 161, combined with Figure 3 The mounting frame 170 is provided with a heating channel 171, and the air guiding channel 161 is connected with the heating channel 171 to form the air duct. The air guiding channel 161 is arranged near the air inlet 111, and the heating channel 171 is arranged near the air outlet 112.

[0037] Combination Figure 4 The wind wheel 120 is arranged in the air guide channel 161, and the output shaft of the motor 140 is plugged into the wind wheel 120. The control unit controls the motor 140 to work, so as to drive the wind wheel 120 to rotate through the motor 140 to form cold air, and the cold air is output toward the heating channel 171.

[0038] Combination Figure 3The heating component 130 is disposed in the heating channel 171, and the control unit controls the heating component 130 to work so that the heating component 130 generates heat. When the cold air generated by the wind wheel 120 flows into the heating channel 171, the heat generated by the heating component 130 heats the cold air, so that the cold air becomes hot air, and the hot air is output to the outside of the heater 100 through the air outlet 112 to increase the temperature of the external environment.

[0039] In this embodiment, combined with Figure 4 The volute tongue 150 is arranged in the air guide channel 161 of the volute 160. The volute tongue 150 cooperates with the volute 160 so that the heater 100 can output hot air to the outside world well and increase the outside temperature.

[0040] Specifically, the volute 160 is used to guide the rotation of the wind formed by the wind wheel 120, so that the hot air output by the heater 100 can be evenly output from the air outlet 112, to ensure that the hot air can be effectively and evenly distributed to the outside, for example, distributed to every corner of the indoor environment, so as to improve the heating efficiency. The volute tongue 150 is used to reduce the backflow of the wind generated by the wind wheel 120 in the air guide channel 161 of the volute 160, so as to reduce the noise during the operation of the heater 100, so that the heater 100 can maintain a low operating noise while providing hot air, creating a more comfortable use environment for the user. Therefore, the volute 160 and the volute tongue 150 cooperate with each other in the heater 100 to play an important role in guiding the wind flow, reducing noise and optimizing aerodynamic performance, providing users with a more efficient, comfortable and quiet use experience.

[0041] In a typical embodiment of the present invention, Figure 4 and Figure 5 The air guide channel 161 includes an inlet (the inlet is called the air guide inlet 1611) and an outlet (the outlet is called the air guide outlet 1612), the air guide inlet 1611 is connected to the air inlet 111, and the air guide outlet 1612 is connected to the heating channel 171. The volute tongue 150 is disposed in the air guide channel 161, and the volute tongue 150 cooperates with the volute 160 to enclose and form the air guide outlet 1612, guiding the wind in the air guide channel 161 to flow from the air guide outlet 1612 to the heating channel 171.

[0042] The volute tongue 150 is pivotally disposed in the volute 160 so that the volute tongue 150 can rotate relative to the volute 160. The opening size of the air guide outlet 1612 can be controlled by controlling the rotation angle of the volute tongue 150 relative to the volute 160, that is, controlling the deflection of the volute tongue 150 relative to the volute 160, thereby controlling the air outlet volume per unit time of the air guide outlet 1612 by controlling the opening size of the air guide outlet 1612, and further controlling the hot air output efficiency of the heater 100 by the air outlet volume.

[0043] In this embodiment, combined with Figure 5 The volute 160 includes an air guide plate 162 and a pair of end covers 163, the pair of end covers 163 are arranged at intervals along the vertical direction of the heater 100, the air guide plate 162 is disposed between the pair of end covers 163, and the air guide plate 162 is respectively connected to the pair of end covers 163 to form the volute 160, and the air guide channel 161 is also formed between the air guide plate 162 and the pair of end covers 163. The end cover 163 is provided with a rotation hole 1632, and the rotation shafts (not shown) at both ends of the wind wheel 120 are respectively inserted into the rotation holes 1632 of the pair of end covers 163, so that the wind wheel 120 can rotate relatively.

[0044] Combination Figure 6 The volute tongue 150 is disposed between the pair of end covers 163. The volute tongue 150 is a long strip structure. A pivot shaft 151 is provided at each end of the volute tongue 150. Figure 5 A pivot hole 1632 is provided on the end cover 163, and the pivot shafts 151 on both ends of the volute tongue 150 are respectively inserted into the pivot holes 1632 of the pair of end covers 163, so that the volute tongue 150 can rotate relative to the volute 160, so that the opening size of the air guide outlet 1612 can be adjusted by the volute tongue 150, thereby adjusting the air outlet volume of the air guide outlet 1612.

[0045] It is understandable that, when the speed of the wind wheel 120 is the same, when the working power of the heating component 130 of the heater 100 is relatively small, that is, when the heat generated is relatively small, the air volume per unit time of the air guide channel 161 needs to be reduced so that the heating component 130 can heat the relatively small amount of wind to a predetermined temperature; when the working power of the heating component 130 of the heater 100 is relatively large, that is, when the heat generated is relatively large, the air volume per unit time of the air guide outlet 1612 needs to be increased so that the heating component 130 can also heat the relatively large amount of wind to a predetermined temperature, so that the heat of the heating component 130 can be output to the outside of the heater 100 in time, so as to avoid the heat from accumulating in the heater 100 and burning the parts of the heater 100, such as the motor 140, plastic parts, etc. Therefore, it is necessary to control the air volume per unit time of the air guide channel 161 according to the working power of the heating component 130, so as to control the hot air output efficiency of the heater 100.

[0046] In the present utility model, combined with Figure 4 By controlling the rotation of the volute tongue 150 relative to the volute 160, the opening size of the air guide outlet 1612 is controlled, thereby controlling the air volume of the air guide channel 161. In order to make the heater 100 of the present invention well control the opening size of the air guide outlet 1612. In the present invention, the rotation of the volute tongue 150 is controlled by setting a thermal deformation member 190 to control the air volume of the air guide channel 161.

[0047] Specifically, the thermal deformation member 190 is made of a thermal expansion material, that is, the thermal deformation member 190 has thermal expansion and contraction characteristics. When the thermal deformation member 190 is heated, the length is extended; when the thermal deformation member 190 is cooled, the length is shortened. Preferably, the thermal deformation member 190 is made of a material with a large thermal expansion coefficient, such as polypropylene, SME material, etc.

[0048] Combination Figure 7 The thermal deformation member 190 is a long strip structure, and the two ends of the thermal deformation member 190 are respectively a first end 191 and a second end 192, the first end 191 is connected to the volute tongue 150, and the second end 192 is connected to the volute 160. When the thermal deformation member 190 senses a temperature change, the thermal deformation member 190 changes its own length, and by changing its own length, it pushes or pulls the volute tongue 150 to rotate relative to the volute 160, that is, the volute tongue 150 is deflected relative to the volute 160 to change the opening size of the air outlet 112.

[0049] Specifically, combined Figure 4When the thermal deformation member 190 is heated, the thermal deformation member 190 extends its length, so that the thermal deformation member 190 pushes the volute tongue 150 relatively away from the second end 192, so as to expand the opening size of the air guide outlet 1612 and increase the air flow of the air guide channel 161. When the temperature of the thermal deformation member 190 decreases, the thermal deformation member 190 shortens its length, so that the thermal deformation member 190 pulls the volute tongue 150 relatively close to the second end 192, so as to reduce the opening size of the air guide outlet 1612 and reduce the air flow of the air guide channel 161.

[0050] In this embodiment, the rotation angle of the volute tongue 150 relative to the volute 160 is associated with the material and original length of the thermal deformation member 190. After the utility model discloses the relevant technical solutions, those skilled in the art can obtain the manufacturing materials and lengths of the thermal deformation members 190 applied to different heaters 100 through experiments to adapt to different heaters 100. To save space, it will not be repeated here.

[0051] In one embodiment, in combination Figure 6 and Figure 7 The end of the volute tongue 150 is also provided with an escape notch 152, and the escape notch 152 is arranged corresponding to the first end 191 of the thermal deformation member 190, and the first end 191 can be inserted into the escape notch 152, and the first end 191 is connected to the volute tongue 150 in the escape notch 152. The escape notch 152 can limit the rotation angle of the volute tongue 150 to prevent the volute tongue 150 from rotating too much and causing the volute tongue 150 to fail.

[0052] In one embodiment, in combination Figure 4 and Figure 5 , the end cover 163 is also provided with a limiting protrusion 164, the limiting protrusion 164 is arranged on the deflection path of the volute tongue 150, and the limiting protrusion 164 is used to constrain the rotation angle of the volute tongue 150, so as to prevent the volute tongue 150 from rotating too much and causing failure of the volute tongue 150. In this embodiment, the limiting protrusion 164 and the avoidance notch 152 are both located on the deflection path of the volute tongue 150, and the limiting protrusion 164 and the avoidance notch 152 define the deflection range of the volute tongue 150 in the deflection path, so that the volute tongue 150 can only rotate and deflect in the deflection range, so as to prevent the volute tongue 150 from rotating too much and causing failure.

[0053] In another embodiment, in combination Figure 6 and Figure 7, the first end 191 is provided with a plug hole 1911, the avoidance notch 152 is provided with a plug shaft 153, the plug shaft 153 is plugged into the plug hole 1911, so that the first end 191 is connected to the volute tongue 150. Alternatively, the first end 191 is provided with a plug shaft 153, the avoidance notch 152 is provided with a plug hole 1911, and the plug shaft 153 is plugged into the plug hole 1911.

[0054] In one embodiment, in combination Figure 4 The thermal deformation member 190 is disposed on the end cover 163, and the second end 192 of the thermal deformation member 190 is connected to the volute 160, and the second end 192 is disposed close to the heating channel 171, so that the thermal deformation member 190 can well receive the heat dissipated by the heating component 130, so that the thermal deformation member 190 changes its length when heated, pushes or pulls the volute tongue 150 to rotate, and changes the opening size of the air guide outlet 1612. Preferably, the second end 192 is threadedly connected to the volute 160.

[0055] Specifically, the second end 192 is connected to the end cover 163. Alternatively, the second end 192 is connected to the air guide plate 162. Alternatively, the second end 192 is connected to the end cover 163 and the air guide plate 162 respectively.

[0056] In one embodiment, in combination Figure 4 The heater 100 is provided with a pair of thermal deformation parts 190, which are respectively arranged on the pair of end covers 163, that is to say, the pair of thermal deformation parts 190 are respectively connected to the volute tongue 150 at both ends of the volute 160 in the vertical direction, and the pair of thermal deformation parts 190 cooperate with each other to control the rotation of the volute tongue 150, so as to control the size of the air guide opening through the volute tongue 150, thereby controlling the air outlet of the air guide channel 161, and then adjusting the hot air output size of the heater 100, avoiding heat accumulation in the heater 100, and protecting the heater 100.

[0057] To summarize, the heater of the present invention pivotally sets the volute tongue on the volute, and connects the volute tongue and the volute through a thermal deformation member. The thermal deformation member controls the opening size of the air outlet defined by the volute tongue and the volute based on the thermal expansion and contraction characteristics, so as to control the air outlet of the air guide channel, thereby controlling the hot air output efficiency of the heater.
