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 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 waste of energy, 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

[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 unit operates at a higher heating power than the second heating unit, so that the heat emitted by the first heating unit is higher than the heat emitted by the second heating unit.

[0019] On the other hand, in the heater of the present invention, the first heating unit operates at a higher heating power than the second heating unit, so that the heat emitted by the first heating unit is higher than the heat emitted by the second heating unit, so that the heat emitted by the first heating unit is heat transferred with the second heating unit, and then the heat emitted by the first heating unit and the heat emitted by the second heating unit are merged with each other, and the temperature of the air heated by the first heating unit is reduced, so that the heater outputs a heat flow with an appropriate temperature to the outside, so as to avoid burning the user and avoiding the occurrence of fire.

In addition, the "connection" or "coupling" used here may include wireless connection or wireless coupling. The term "and / or" used here includes all or any unit and all combinations of one or more associated listed items.

[0027] Those skilled in the art will understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of ordinary technicians in the field to which the utility model belongs. 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 units of the heater have different heating powers, so that the at least two heating units 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 units generate different temperatures when working, the heating unit with a larger heating power will transfer heat to the heating unit with a lower heating power, and the heat generated by the heating unit with a larger heating power is balanced by the heating unit 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 , Figure 3 and Figure 4 The heater 100 includes a control unit (not shown), a housing 110 and a plurality of heating components 120 , wherein the plurality of heating components 120 are disposed in the housing 110 .

[0030] Combination Figure 4The multiple heating components 120 are arranged side by side, and each heating component 120 includes one or more heating units 121. The control unit is electrically connected to the heating units 121 of the multiple heating components 120. The control unit controls the operation of the heating units 121. When the heating units 121 are working, heat is generated, and the surrounding air is heated by the heat to generate hot air. The hot air is dispersed 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, it is assumed that the environment in which the heater 100 is located is an indoor environment, but it should not be understood as a limitation to the present invention.

[0031] The plurality of heating components 120 include a first heating component 130 and a second heating component 140, and the first heating component 130 and the second heating component 140 are arranged adjacent to each other. The first heating component 130 includes a first heating unit 131, and the second heating component 140 includes a plurality of second heating units 141, and the plurality of second heating units 141 are arranged in sequence along the axial direction of the first heating unit 131.

[0032] The control unit is electrically connected to the first heating unit 131 and the second heating unit 141 respectively. Under the control of the control unit, the heating power of the first heating unit 131 is greater than the heating power of the second heating unit 141. It can be understood that when working, the heat generated by the first heating unit 131 is greater than the heat generated by the second heating unit 141.

[0033] Because the heating power of the first heating unit 131 is higher than the heating power of the second heating unit 141, the temperature of the hot air heated by the first heating unit 131 (the hot air is called the first hot air) is greater than the temperature of the hot air heated by the second heating unit 141 (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 hot air expands due to the heat and its density decreases, while the temperature of the second hot air is lower than that of the first hot air, and the density of the second hot air is higher than that of the first hot air. The second 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 second hot air, that is, air convection is formed between the first heating unit 131 and the second heating unit 141. Due to the air convection, the first hot air and the second hot air can be accelerated to flow out of the heater 100, thereby increasing the rate of increase of indoor temperature.

[0035] In this embodiment, the first heating unit 131 and the second heating unit 141 are arranged side by side and adjacent to each other, so as to form strong convection between the first heating unit 131 and the second heating unit 141 and facilitate heat transfer.

[0036] In one embodiment, in the parallel direction of the plurality of heating components 120, the distance between the first heating unit 131 and the second heating unit 141 is 10-200 mm, so that there is enough space between the first heating unit 131 and the second heating unit 141 to form convection. In this embodiment, in the parallel direction, it is recommended that the distance between the first heating unit 131 and the second heating unit 141 is 10-100 mm.

[0037] Traditional heaters have multiple heating units 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 unit is consistent, the temperature of each heating unit is the same, so that convection cannot be formed between the heating units. Moreover, because multiple heating units 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.

[0038] However, in the heater 100 of the present invention, since the heating power of the first heating unit 131 is different from the heating power of the second heating unit 141, air convection is formed between the first heating unit 131 and the second heating unit 141, so that the first hot air and the second hot air can be quickly dissipated to change the indoor temperature. The heater 100 of the present invention saves electricity compared to traditional heaters, increases the indoor temperature quickly, and meets the public's demand for environmentally friendly green life.

[0039] 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.

[0040] The control unit controls the first heating unit 131 to heat to a first temperature, and the control unit controls the second heating unit 141 to heat to a second temperature, wherein the first temperature is greater than the second temperature. When the heater 100 is working, heat transfer occurs between the first heating unit 131 and the second heating unit 141 because the first temperature is higher than the second temperature.

[0041] In order to quickly raise the indoor temperature, traditional heaters usually control multiple heating units 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.

[0042] The first temperature of the first heating unit 131 of the heater 100 of the present invention is greater than the second temperature of the second heating unit 141, so that heat transfer is generated between the first heating unit 131 and the second heating unit 141, that is, the temperature of the first hot air output by the first heating unit 131 is lowered by the second heating unit 141, and the temperature of the second hot air is also increased by the first hot air. It can be understood that the first hot air and the second hot air merge 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.

[0043] Although the heating power of the first heating unit 131 is relatively high, the heating power of the second heating unit 141 is relatively low, so that the first heating unit 131 and the second heating unit 141 can cooperate to output hot air of suitable temperature. Compared with a plurality of heating units of the same power in a conventional heater, the heater 100 of the utility model saves electricity, increases indoor temperature quickly, and meets the public's demand for environmentally friendly green living.

[0044] In this embodiment, it is recommended that the first temperature of the first heating unit 131 is above 100° C. and the second temperature of the second heating unit 141 is below 100° C., but this should not be construed as a limitation to the present invention.

[0045] In a typical embodiment of the present invention, the multiple heating components 120 are arranged side by side, so that the first heating unit 131 and the second heating unit 141 are also arranged side by side, and the first heating component 130 and the second heating component 140 are arranged adjacent to each other, so that the first heating unit 131 and the second heating unit 141 are also arranged adjacent to each other, so as to form air convection and heat transfer between the first heating unit 131 and the second heating unit 141.

[0046] In this embodiment, the axial length of the first heating unit 131 is greater than or equal to the sum of the axial lengths of the multiple second heating units 141 of the second heating component 140, so that the first heating unit 131 can form air convection and heat transfer with each second heating unit 141 of the second heating component 140, that is, the same heat transfer is generated between the first heating unit 131 and the multiple second heating units 141, thereby avoiding local overheating, protecting the heater 100, and making the rate of hot air output by the heater 100 approach to consistency, thereby avoiding local rates that are too fast or too slow, and improving the user experience.

[0047] 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 is arranged opposite to the top plate 112, and 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 units 121 can output hot air to the outside through the plurality of ventilation holes 114 to increase the indoor temperature.

[0048] 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 hot air rises along the direction of heat rise, when the heater 100 is working, after entering the air inlet space, the external air enters the area where the first heating component 130 and the second heating component 140 are located through the ventilation holes 114 on the bottom plate 111 along the direction of heat rise, so as to increase the rate at which the first heating unit 131 and the second heating unit 141 heat the air, and increase the rate at which the hot air heated by the first heating unit 131 and the second heating unit 141 is output to the outside.

[0049] In one embodiment, in combination Figure 4, the heating unit 121 includes a heating rod 1211 and a plurality of heat sinks 1212, and the plurality of heat sinks 1212 are connected in series to the heating rod 1211. When the heating rod 1211 is powered on, the heating rod 1211 generates heat, and the heat on the heating rod 1211 is transferred to the plurality of heat sinks 1212, so as to quickly dissipate the heat through the plurality of heat sinks 1212. In this embodiment, the heating unit 121 is provided with two heating rods 1211, the two heating rods 1211 are arranged in parallel, and the plurality of heat sinks 1212 are simultaneously passed through the two heating rods 1211, so as to quickly increase the indoor temperature through the two heating rods 1211. In this embodiment, the structures of the heating units 121 of the heater 100 are the same. In one embodiment, the heat sink 1212 is made of copper metal material or aluminum metal material.

[0050] Combination Figure 3 and Figure 4 A pair of support plates 116 are also provided in the shell 110. The pair of support plates 116 are respectively provided at two ends of the axial direction of the first heating unit 131. The two ends of the heating rod 1311 of the first heating unit 131 are respectively inserted into the pair of support plates 116 to support the first heating unit 131.

[0051] In this embodiment, the second heating component 140 is provided with two second heating units 141, and the two second heating units 141 are sequentially arranged along the axial direction of the first heating unit 131, and the two second heating units 141 respectively cooperate with the first heating unit 131 to form air convection and heat transfer. The sum of the axial lengths of the two second heating units 141 is less than or equal to the axial length of the first heating unit 131.

[0052] In this embodiment, the heater 100 is further provided with a control box 160, and the control box 160 is used to accommodate the control unit. The control box 160 is arranged between the two second heating units 141 of the second heating component 140. When the control box 160 is arranged between the two second heating units 141, in the axial direction of the first heating unit 131, the sum of the axial length of the control box 160 and the axial length of the two second heating units 141 is equal to or less than the axial length of the first heating unit 131. In this embodiment, it is recommended that the sum of the axial length of the control box 160 and the axial length of the two second heating units 141 is equal to the axial length of the first heating unit 131.

[0053] The control box 160 includes two side walls that are respectively arranged opposite to the pair of support plates 116. The two side walls are respectively referred to as a first side wall 161 and a second side wall (not shown), and the pair of support plates are respectively referred to as a first support plate 117 and a second support plate 118. The first side wall 161 is opposite to the first support plate 117, spaced apart and adjacent to each other, and the second side wall is opposite to the second support plate 118, spaced apart and adjacent to each other.

[0054] The two second heating units of the second heating component 140 are respectively called the third heating unit 142 and the fourth heating unit 143, and the two ends of the heating rod 1421 of the third heating unit 142 are respectively inserted into the first side wall 161 and the first support plate 117, and the two ends of the heating rod 1431 of the fourth heating unit 143 are respectively inserted into the second side wall and the second support plate 118, thereby allowing the two second heating units 141 to be stably arranged in the heater 100 through the two side walls of the control box 160 and the pair of support plates 116.

[0055] In one embodiment, a power supply is also provided in the control box 160, and the power supply is electrically connected to the control unit, and the power supply supplies power to the multiple heating units 121. The power supply is also provided with a power supply line 164, and the power supply line 164 is led to the outside through the control box 160 and the housing 110 to facilitate connection with an external power supply. Preferably, the control box 160 is made of a heat-insulating material to prevent the heat emitted by the first heating unit 131 and / or the second heating unit 141 from burning the electronic components in the control box 160.

[0056] In one embodiment, the plurality of heating units 121 are arranged in parallel, and the parallel arrangement of the plurality of heating units 121 can significantly improve the heating efficiency of the heater 100. Each heating unit 121 works independently, and the plurality of heating units 121 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 number of working heating units 121 can be adjusted according to actual needs, and flexible power adjustment can be achieved to meet the heating needs in different scenarios.

[0057] To sum up, the heating power of the first heating unit of the heater of the present invention is higher than the heating power of the second heating unit. The first heating unit and multiple second heating units cooperate with each other to simultaneously form air convection and heat transfer, so that the heater can quickly output hot air of suitable temperature outside the heater to increase the indoor temperature.
