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 important branch of household heating equipment, skirting heaters have won the favor of consumers with their unique design and efficient heating performance in winter. Heaters not only provide people with a warm and comfortable living environment, help people resist the invasion of cold weather, but also greatly improve people's quality of life. However, with the continuous advancement of technology and consumers' increasing requirements for the performance of heating equipment, traditional skirting heaters have gradually exposed some problems and limitations.

[0003] On the one hand, traditional skirting heaters dissipate heat slowly and are not energy-efficient. Traditional skirting heaters generally adopt a design with multiple heating elements arranged in parallel. These heating elements have the same power. Although this simplifies the manufacturing process, it also brings about the problem of slow heat dissipation. Since the heating elements are stacked on top of each other, the heat is greatly hindered during the transfer process, resulting in the heater being inefficient in raising the ambient temperature. This not only prolongs the time it takes to raise the indoor temperature and increases the user's waiting time, but also causes unnecessary energy waste, which does not meet the urgent needs of modern families for efficient and energy-saving heating equipment. Moreover, multiple heating elements arranged in parallel will cause heat to be concentrated inside the heater, causing the outer shell of the heater to overheat, and when the user touches the outer shell, the user will be scalded.

[0004] On the other hand, traditional baseboard heaters have some safety hazards. Since the heating element is usually heated to a high temperature when working, even exceeding 100°C, or even reaching above 200°C, there is a great safety hazard when the heating element directly dissipates heat to the outside. For users, especially children or elderly people with limited mobility, since they lack sufficient self-protection awareness or mobility, once they accidentally come into contact with the high-temperature gas output by the heater, they are likely to suffer high-temperature burns, and may even cause serious scalding accidents. In addition, long-term high-temperature operation may also cause serious consequences such as fire, posing a great threat to the safety of users' lives and property. Utility Model Content

[0005] The primary purpose of the present invention is to solve at least one of the above problems and provide a heater.

[0006] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0007] A heater is provided to meet one of the purposes of the utility model, including a control unit, a shell, and a plurality of heating components installed in the shell and controlled by the control unit, the plurality of heating components are stacked along the heat rise direction, the control unit controls a first heating component located at a lower layer in the heat rise direction to operate at a higher heating power relative to a heating component located at a higher layer, and the control unit controls at least one heating component located at the same layer as the first heating component to operate at a lower heating power relative to the first heating component.

[0008] Furthermore, the multiple heating components in the lower layer are arranged side by side, and the lower layer also includes a third heating component. The control unit controls the third heating component to operate at a lower heating power than the first heating component, and at least one of the third heating components is arranged adjacent to the first heating component.

[0009] In one embodiment, in the projection direction of the horizontal plane, the projection of the at least one heat generating component in the higher layer coincides or overlaps with the projection of the first heat generating component.

[0010] In one embodiment, in the projection direction of the horizontal plane, the projection of the heat generating component in the next higher layer does not intersect with the projection of the third heat generating component.

[0011] Specifically, the distance between two adjacent heat generating components in the same layer is 10-200 mm, and in the heat rising direction, the distance between the heat generating component on the lower layer and the heat generating component on the higher side is 10-200 mm.

[0012] Specifically, the multiple heating components are arranged in parallel.

[0013] Specifically, the heating component includes a heating rod and a plurality of heat sinks connected in series to the heating rod, and the heat sinks are made of aluminum metal material or copper metal material.

[0014] Specifically, a pair of support plates are provided in the shell, and two ends of the heating rod of the heating component are correspondingly inserted into the pair of support plates.

[0015] Specifically, the shell includes a bottom plate, a top plate and a plurality of side plates, the bottom plate is arranged opposite to the top plate, the plurality of side plates are arranged around the bottom plate, and a plurality of ventilation holes are respectively provided on the bottom plate, the top plate and at least one side plate.

[0016] Specifically, a plurality of supporting feet are provided on the bottom surface of the bottom plate, and an air inlet space is formed between the supporting feet and the bottom plate.

[0017] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0018] On the one hand, in the heater of the present invention, the first heating component operates at a higher heating power than at least one heating component on the same layer and the heating component on a higher layer, so that the heat emitted by the first heating component is higher than the heat emitted by at least one heating component on the same layer and the heating component on a higher layer. Due to the difference in heat, air convection is formed between the first heating component and at least one heating component on the same layer, and air convection is formed between the first heating component and the heating component on a higher layer. It can be understood that the two air convections are superimposed on each other to form strong convection, so that the heater can quickly dissipate heat to the outside, quickly increase the indoor temperature, and prevent hot air from gathering in the heater, thereby avoiding heating the outer shell to a high temperature and protecting the user.

[0019] On the other hand, in the heater of the present invention, the first heating component operates at a higher heating power than at least one heating component on the same layer and the heating component on a higher layer, so that the heat emitted by the first heating component is higher than the heat emitted by at least one heating component on the same layer and the heating component on a higher layer, so that the heat emitted by the first heating component is respectively transferred to at least one heating component on the same layer and the heating component on a higher layer, and then the heat emitted by the first heating component is integrated with the heat of at least one heating component on the same layer and the heat emitted by the heating component on a higher layer, and the temperature of the air heated by the first heating component is reduced, so that the heater outputs a heat flow with appropriate temperature to the outside to avoid burning users and avoiding the occurrence of fire.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0028] The utility model provides a heater, wherein at least two of the multiple heating components of the heater have different heating powers, so that the at least two heating components generate different temperatures when working, resulting in a temperature difference, and convection is formed due to the temperature difference, thereby accelerating the efficiency of heat dissipation of the heater to the outside. Moreover, because the at least two heating components generate different temperatures when working, the heating component with a larger heating power will transfer heat to the heating component with a lower heating power, and the heat generated by the heating component with a larger heating power is balanced by the heating component with a lower heating power, so as to avoid the heater from outputting high-temperature airflow to the outside, thereby protecting the user.

[0029] In a typical embodiment of the present utility model, Figure 1 and Figure 4The heater 100 includes a control unit (not shown), a housing 110 and a plurality of heating components 130 . The plurality of heating components 130 are disposed in the housing 110 , and the control unit is electrically connected to the heating components 130 , respectively.

[0030] The control unit controls the operation of the heating component 130. The heating component 130 generates heat when working, and heats the surrounding air through the heat to generate hot air. The hot air radiates or flows outside the heater 100 to change the temperature of the environment outside the heater 100. Generally speaking, the heater 100 is set indoors. For the convenience of description below, the environment in which the heater 100 is located is assumed to be an indoor environment, but this should not be construed as a limitation to the present invention.

[0031] The plurality of heating components 130 are stacked along the heat rising direction and are divided into multiple layers, each layer being provided with one or more heating components 130. In this embodiment, a first layer and a second layer are provided, and the second layer is provided on the upper side of the first layer, that is, the first layer and the second layer are provided up and down along the heat rising direction.

[0032] In this embodiment, combined with Figure 4 The first layer is provided with a first heating component 131 and a third heating component 133, and the second layer is provided with a second heating component 132. Under the control of the control unit, the heating power of the first heating component 131 is respectively greater than the heating power of the second heating component 132 and the heating power of the third heating component 133. It can be understood that when working, the heat generated by the first heating component 131 is respectively greater than the heat generated by the second heating component 132 and the heat generated by the third heating component 133.

[0033] Because the heating power of the first heating component 131 is higher than the heating power of the second heating component 132, the temperature of the hot air heated by the first heating component 131 (the hot air is called the first hot air) is greater than the temperature of the hot air heated by the second heating component 132 (the hot air is called the second hot air), so that there is a temperature difference between the first hot air and the second hot air.

[0034] The first heating component 131 and the second heating component 132 are arranged up and down, and the first hot air expands due to the heat and its density decreases, so that it rises along the heat rising direction; and the temperature of the second hot air is lower than that of the first hot air, so that the density of the second hot air is higher than that of the first hot air, so that air convection is formed between the first hot air and the second hot air, that is to say, air convection is formed between the first heating component 131 and the second heating component 132. Due to the air convection, the first hot air and the second hot air can be accelerated to flow outside the heater 100, thereby increasing the rate of increase of indoor temperature.

[0035] The first heating component 131 and the second heating component 132 are arranged adjacent to each other in the up-and-down direction of the heat rise, so as to form strong convection between the first heating component 131 and the second heating component 132 and facilitate heat transfer. Specifically, in the projection direction of the horizontal plane, the projection of the first heating component 131 and the projection of the second heating component 132 are overlapped or coincident, so that strong air convection can be quickly formed between the first heating component 131 and the second heating component 132, and heat transfer between the first heating component 131 and the second heating component 132 is facilitated. In this embodiment, the horizontal plane is perpendicular to the heat rise direction, and the horizontal plane is parallel to the sea level.

[0036] In one embodiment, in the heat rise direction, the distance between the first heat generating component 131 and the second heat generating component 132 is 10-200 mm, so that there is enough space between the first heat generating component 131 and the second heat generating component 132 to form convection. In this embodiment, in the heat rise direction, it is recommended that the distance between the first heat generating component 131 and the second heat generating component 132 is 10-100 mm.

[0037] In one embodiment, in the heat rise direction, the third heating component 133 is also arranged up and down with the second heating component 132 along the heat rise direction, and the heating power of the third heating component 133 is the same as or similar to the heating power of the second heating component 132. In order to prevent the second heating component 132 from blocking the third heating component 133 from outputting hot air to the outside, in the projection direction of the horizontal plane, the projection of the third heating component 133 does not intersect with the projection of the second heating component 132, so as to prevent the second heating component 132 from blocking the third heating component 133 from outputting hot air to the outside.

[0038] In this embodiment, the first heating component 131 and the third heating component 133 are arranged in the same layer, the first heating component 131 and the third heating component 133 are arranged adjacent to each other, and the heating power of the first heating component 131 is greater than the heating power of the third heating component 133 .

[0039] Because the heating power of the first heating component 131 is higher than that of the third heating component 133, the temperature of the first hot air heated by the first heating component 131 is greater than the temperature of the hot air heated by the third heating component 133 (the hot air is called the third hot air), so that there is a temperature difference between the first hot air and the third hot air.

[0040] The first hot air expands due to the heat and its density decreases, while the temperature of the third hot air is lower than that of the first hot air, and the density of the third hot air is higher than that of the first hot air. The third hot air with higher density diffuses toward the first hot air with lower density, so that air convection is formed between the first hot air and the third hot air, that is, air convection is formed between the first heating component 131 and the third heating component 133. Due to the air convection, the first hot air and the third hot air can be accelerated to flow outside the heater 100, thereby increasing the rate of increase of indoor temperature.

[0041] In this embodiment, the first heating component 131 and the third heating component 133 are arranged side by side in the same layer, and the first heating component 131 and the third heating component 133 are arranged adjacent to each other, so as to form strong convection between the first heating component 131 and the third heating component 133 and facilitate heat transfer.

[0042] In one embodiment, in the arrangement direction between the plurality of heating components 130 of the first layer, the distance between the first heating component 131 and the third heating component 133 is 10-200 mm, so that there is enough space between the first heating component 131 and the third heating component 133 to form convection. In this embodiment, in the arrangement direction, it is recommended that the distance between the first heating component 131 and the third heating component 133 is 10-100 mm.

[0043] As a result, the air convection between the first hot air and the second hot air and the air convection between the first hot air and the third hot air are superimposed on each other, further enhancing the air convection inside the heater 100, so that the heat generated by the first heating component 131, the second heating component 132 and the third heating component 133 can be dissipated to the outside of the heater 100 more quickly, thereby quickly increasing the indoor temperature.

[0044] Traditional heaters have multiple heating components stacked on top of each other to increase indoor temperature and improve efficiency more quickly. When the heater is working, since the power of each heating component is consistent, the temperature of each heating component is the same, so that convection cannot be formed between the heating components. Moreover, because multiple heating components are stacked on top of each other, heat is greatly hindered during the transfer process, resulting in the heater being inefficient in raising the temperature of the external environment. This not only prolongs the time it takes to raise the indoor temperature and increases the waiting time for users, but also causes unnecessary energy waste, which does not meet the urgent needs of modern families for efficient and energy-saving heating equipment.

[0045] However, in the heater 100 of the present invention, since the heating power of the first heating component 131 is different from the heating power of the second heating component 132 and the heating power of the third heating component 133, air convection is formed between the first heating component 131 and the second heating component 132 and the third heating component 133 respectively, so that the first hot air, the second hot air and the third hot air can be quickly dissipated to change the indoor temperature. The heater 100 of the present invention saves electricity compared with traditional heaters, increases the indoor temperature quickly, and meets the public's demand for environmentally friendly green life.

[0046] Heat transfer is the process of heat flowing from a hot object to a cold object. According to the second law of thermodynamics, heat always spontaneously transfers from a hotter object to a colder object until the two reach thermal equilibrium, that is, their temperatures are equal. In this process, the hot object transfers heat to the cold object through radiation, conduction or convection until the temperatures of the two become the same.

[0047] The control unit controls the first heating component 131 to heat to a first temperature, the control unit controls the second heating component 132 to heat to a second temperature, and the control unit controls the third heating component 133 to heat to a third temperature, and the first temperature is respectively greater than the second temperature and the third temperature. When the heater 100 is working, since the first temperature is respectively higher than the second temperature and the third temperature, the first heating component 131 will generate heat transfer with the second heating component 132 and the third heating component 133.

[0048] In order to quickly raise the indoor temperature, traditional heaters usually control multiple heating components to heat to above 100°C or even above 200°C, so as to quickly raise the indoor temperature. However, when users get close to traditional heaters, they are easily burned by the high-temperature gas output by traditional heaters, and even fires may occur.

[0049] The first temperature of the first heating component 131 of the heater 100 of the present invention is respectively greater than the second temperature of the second heating component 132 and the third temperature of the third heating component 133, so that heat transfer is generated between the first heating component 131 and the second heating component 132 and the third heating component 133, that is, the temperature of the first hot air output by the first heating component 131 is lowered by the second heating component 132 and the third heating component 133, and the temperature of the second hot air and the third hot air is also increased by the first hot air. It can be understood that the first hot air, the second hot air and the third hot air are integrated with each other to form hot air of suitable temperature, so that the user will not be burned even if he is close to the heater 100.

[0050] Although the heating power of the first heating component 131 is relatively high, the heating power of the second heating component 132 and the third heating component 133 is relatively low, so that the first heating component 131, the second heating component 132 and the third heating component 133 can cooperate to output hot air of suitable temperature. Compared with a plurality of heating components of the same power in a conventional heater, the heater 100 of the utility model is more energy-efficient than a conventional heater, increases the indoor temperature quickly, and meets the public's demand for environmentally friendly green living.

[0051] In this embodiment, it is recommended that the first temperature of the first heating component 131 is above 100°C, the second temperature of the second heating component 132 is below 100°C, and the third temperature of the third heating component 133 is below 100°C, but this should not be understood as a limitation to the present invention.

[0052] In a typical embodiment of the present invention, Figure 1 and Figure 2 The housing 110 includes a bottom plate 111, a top plate 112, and a plurality of side plates 113. The bottom plate 111 and the top plate 112 are arranged opposite to each other along the heat rising direction. The plurality of side plates 113 are arranged around the bottom plate 111. The bottom plate 111, the top plate 112, and the plurality of side plates 113 are arranged to form a closed structure of the housing 110. In this embodiment, a plurality of ventilation holes 114 are respectively provided on the bottom plate 111, the top plate 112, and at least one side plate 113, so that the plurality of heating components 130 can output hot air to the outside through the plurality of ventilation holes 114 to increase the indoor temperature.

[0053] A plurality of supporting legs 115 are also provided on the bottom surface of the bottom plate 111, and the housing 110 is supported by the plurality of supporting legs 115, so that a gap (the gap is called an air inlet space) is formed between the bottom plate 111 and the ground or the working surface. Since the hot air rises along the heat rising direction, when the first heating component 131 is working, after entering the air inlet space, the external air enters the area where the first heating component 131 and the third heating component 133 are located through the ventilation holes 114 on the bottom plate 111 along the heat rising direction, so as to increase the rate at which the first heating component 131 and the third heating component 133 heat the air, and increase the rate at which the hot air heated by the first heating component 131 and the third heating component 133 is output to the outside.

[0054] In one embodiment, in combination Figure 4 , the heating component 130 includes a heating rod 134 and a plurality of heat sinks 135, and the plurality of heat sinks 135 are connected in series to the heating rod 134. When the heating rod 134 is powered on, the heating rod 134 generates heat, and the heat on the heating rod 134 is transferred to the plurality of heat sinks 135, so as to quickly dissipate the heat through the plurality of heat sinks 135. In this embodiment, the heating component 130 is provided with two heating rods 134, and the two heating rods 134 are arranged in parallel, and the plurality of heat sinks 135 are simultaneously passed through the two heating rods 134, so as to quickly increase the indoor temperature through the two heating rods 134. In this embodiment, the structures of the heating components 130 of the heater 100 are the same. In one embodiment, the heat sink 135 is made of copper metal material or aluminum metal material.

[0055] Combination Figure 3 and Figure 4 A pair of support plates 116 are further provided in the housing 110. The pair of support plates 116 are respectively provided at two ends of the axial direction of the heating rod 134. The two ends of the heating rod 134 are respectively inserted into the pair of support plates 116 to support the heating component 130. In this embodiment, the plurality of heating components 130 share the pair of support plates 116.

[0056] In one embodiment, the multiple heating components 130 are arranged in parallel, and the parallel arrangement of multiple heating components 130 can significantly improve the heating efficiency of the heater 100. Each heating component 130 works independently, and multiple heating components 130 generate heat at the same time and quickly dissipate the heat to the surrounding environment, which can maximize the use of electrical energy and reduce the loss of heat during the transfer process, thereby quickly increasing the indoor temperature. In addition, due to the parallel arrangement, the working number of the heating components 130 can also be adjusted according to actual needs, realizing flexible power adjustment to meet the heating needs in different scenarios.

[0057] In one embodiment, in combination Figure 3 The heater 100 is further provided with a control box 141, the control unit is arranged in the control box 141, a power supply is further provided in the control box 141, the power supply is electrically connected to the control unit, and the power supply supplies power to the plurality of heating components 130. The power supply is further provided with a power supply line 142, the power supply line 142 is led out to the outside through the control box 141 and the housing 110, so as to be connected to an external power supply.

[0058] To sum up, the heating power of the first heating component of the heater of the present invention is higher than the heating power of the second heating component and the third heating component, so that the heating temperature of the first heating component is higher than the heating temperature of the second heating component and the third heating component, so that the first heating component, the second heating component and the third heating component cooperate with each other to form strong air convection and heat transfer, so that the heater can quickly output hot air of appropriate temperature to the outside, thereby increasing the indoor temperature.
