Description

Technical Field

[0001] The utility model relates to the technical field of bathroom equipment, in particular to a temperature protection structure and a gas water heater comprising the same. Background Art

[0002] As a bathing device, a gas water heater can adjust the water temperature according to human needs. The gas water heater includes a combustion chamber, a radiator and a fan.

[0003] When the existing gas water heater is working, the combustion chamber has the problem of too high surface temperature. Long-term use will cause the combustion chamber shell to be affected by the high temperature and deform. In order to reduce the direct heat conduction between the high-temperature flue gas and the combustion chamber shell, thermal insulation materials such as aluminum silicate are usually used to reduce the surface temperature of the combustion chamber. The cost of using aluminum silicate insulation board is high. At the same time, aluminum silicate will produce powder and other substances falling under long-term high temperature conditions. If the powder and other substances block the burner fire hole, it will affect the combustion performance of the whole machine. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the combustion chamber shell of the gas water heater cannot maintain a low temperature under high-load combustion state, and to provide a temperature protection component and a gas water heater containing the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A temperature protection component is applied to a gas water heater, the gas water heater comprises a combustion chamber and a radiator located above the combustion chamber;

[0007] The temperature protection assembly includes a deformation part, a contact part, a first electrical wire and a second electrical wire, wherein the first electrical wire and the second electrical wire are connected to the heat sink and the deformation part respectively.

[0008] The deformation part is arranged in the combustion chamber; the contact part is connected to the heat sink and arranged close to the deformation part, and both the contact part and the deformation part are conductive;

[0009] The deformation portion can deform with temperature changes and contact the contact portion, so that the first electrical wiring and the second electrical wiring are electrically connected.

[0010] In the present solution, the heat sink is located on the combustion chamber closer to the combustion chamber shell, which is beneficial to evacuate the heat of the combustion chamber shell and prevent its deformation; the deformation part is arranged in the combustion chamber, which is beneficial to the deformation part to sense the heat more quickly and promote its own deformation; the contact part is connected to the heat sink so that after the deformation part and the contact part are connected, the signal is transmitted to the second electrical wire on the heat sink in time, thereby improving the cooling efficiency; both the contact part and the deformation part are conductive so that the signal can be transmitted between the contact part and the deformation part, and the deformation part can deform with the temperature change, which is beneficial to the contact between the deformation part and the contact part to quickly transmit the signal.

[0011] Preferably, the combustion chamber comprises an outer shell having a mounting wall and side walls arranged on both sides of the mounting wall, and the deformation portion is spaced apart from the mounting wall and extends between the two side walls to form a heat insulating space with the mounting wall.

[0012] In the present solution, the provision of the outer shell helps prevent the heat from the combustion chamber from being directly discharged into the environment and causing discomfort to the human body; the spacing between the deformation portion and the mounting wall helps reduce and alleviate the heat transferred from the combustion chamber to the outer shell, that is, helps reduce the temperature of the outer shell; the extension of the deformation portion between the two side walls helps increase the spacing space, that is, the heat-insulating space, and further reduces the temperature of the outer shell.

[0013] Preferably, the deformation portion includes a first plate body and a second plate body, the lower end of the second plate body is overlapped with the first plate body, the upper end of the second plate body is separable from the first plate body, and the expansion coefficient of the second plate body is greater than the expansion coefficient of the first plate body; the first plate body is used to be connected to the outer shell of the combustion chamber, and the second plate body is used to contact the contact portion.

[0014] In the present solution, the lower end of the second plate body overlaps with the first plate body, which helps prevent the second plate body from separating from the first plate body and causing blockage in the combustion chamber. The upper end of the second plate body can be separated from the first plate body, which helps connect the deformation part with the contact part when the temperature rises. The expansion coefficient of the second plate body is greater than the expansion coefficient of the first plate body, which helps better fix the deformation part on the mounting wall of the outer shell. The first plate body is connected to the outer shell of the combustion chamber, and the second plate body is in contact with the contact part. Such a structure allows the signal to be quickly transmitted between the outer shell and the radiator, thereby improving the cooling efficiency.

[0015] Preferably, the contact portion is bent and includes a fixed position and a contact position. The fixed position is horizontally arranged at the bottom of the radiator, and the contact position is vertically located in the combustion chamber. When the deformation portion deforms with temperature changes, the second plate body contacts the contact position to make the first electrical wire and the second electrical wire electrically conductive.

[0016] In the present solution, the contact portion is bent so that the contact portion can be fixed on the radiator and can contact the second plate body. The fixing position is horizontally arranged at the bottom of the radiator to increase the fixing area and improve the fixing effect. The contact position is vertically located in the combustion chamber, so it is arranged close to the second plate body, which is conducive to contact with the second plate body. The vertical arrangement also facilitates disconnection from the second plate body, which is conducive to improving the sensitivity of the temperature protection component.

[0017] Preferably, the upper end of the first plate body is in an inverted U-shape, and a first connecting position is provided at the upper end of the first plate body, the first connecting position is connected to the inner side of the mounting wall of the combustion chamber, and the lower end of the first plate body extends to the lower part of the combustion chamber.

[0018] In this scheme, the upper end of the first plate body is in an inverted U-shape, which is conducive to forming an insulating space between the deformation part and the outer shell, reducing the heat transferred from the combustion chamber to the outer shell, that is, it is conducive to reducing the temperature of the outer shell; the lower end of the first plate body extends to the lower part of the combustion chamber to increase the insulating space, further reduce the heat transferred from the combustion chamber to the outer shell, and further reduce the temperature of the outer shell.

[0019] Preferably, the second plate is closer to the cavity of the housing, and when the deformation portion deforms with temperature changes, the second plate is closer to the middle of the cavity of the housing.

[0020] In this solution, the second plate body is closer to the cavity of the outer shell so as to be in contact with the heat in the combustion chamber more promptly, which is beneficial to improving the cooling efficiency of the temperature protection component. The closer the second plate body is to the middle of the cavity of the outer shell, the higher the heat it contacts, the more promptly it contacts with the contact part, and the faster the temperature of the outer shell can be reduced.

[0021] Preferably, the second electrical wiring is connected to the lower end of the first plate body or the lower part of the second plate body, and the first electrical wiring is connected to the heat sink or the contact part of the heat sink.

[0022] In this solution, since the lower end of the second board body overlaps with the first board body, the connection between the second electrical wire and the lower end of the first board body or the lower part of the second board body is conducive to the second electrical wire receiving a stronger signal; the first electrical wire is connected to the heat sink or contact part of the radiator to adapt to different connection conditions.

[0023] Preferably, temperature protection components are provided on opposite sides of the combustion chamber.

[0024] In this solution, the two relatively sides are the side close to the user and the side far away from the user when the gas water heater is in use. The temperature protection components are provided on both sides to improve the overall heat reduction effect of the combustion chamber.

[0025] Preferably, the temperature protection assembly further includes an electric controller, and the first electric wire and the second electric wire are both electrically connected to the electric controller.

[0026] In this solution, the first electrical equipment line and the second electrical equipment line are both electrically connected to the electric controller so that the first electrical equipment line and the second electrical equipment line are electrically connected and can transmit signals to the electric controller.

[0056] A preferred embodiment is given below and combined with the accompanying drawings to more clearly and completely illustrate the present invention, but the present invention is not limited to the scope of the embodiment.

[0057] like Figures 1 to 3 As shown, the utility model provides a temperature protection component 2, which is applied to a gas water heater 1. The gas water heater 1 includes a combustion chamber 3 and a radiator 4 located above the combustion chamber 3;

[0058] The temperature protection assembly 2 includes a deformation portion 21, a contact portion 22, a first electrical wiring 23 and a second electrical wiring 24. The first electrical wiring 23 and the second electrical wiring 24 are connected to the heat sink 4 and the deformation portion 21, respectively.

[0059] The deformation portion 21 is disposed in the combustion chamber 3; the contact portion 22 is connected to the heat sink 4 and is arranged close to the deformation portion 21, and both the contact portion 22 and the deformation portion 21 are conductive;

[0060] The deformable portion 21 can deform with temperature changes and contact the contact portion 22 to allow the first electrical wiring 23 and the second electrical wiring 24 to be electrically connected.

[0061] In this embodiment, the heat sink 4 is located on the combustion chamber 3 closer to the combustion chamber 3 shell 31, which is beneficial to evacuate the heat of the combustion chamber 3 shell 31 to prevent its deformation; the deformation portion 21 is arranged in the combustion chamber 3, which is beneficial to the deformation portion 21 to sense the heat more quickly and promote its own deformation; the contact portion 22 is connected to the heat sink 4 so that after the deformation portion 21 and the contact portion 22 are connected, the signal is transmitted to the second electrical wire 24 on the heat sink 4 in time, thereby improving the cooling efficiency; the contact portion 22 and the deformation portion 21 are both conductive so that the signal can be transmitted between the contact portion 22 and the deformation portion 21, and the deformation portion 21 can deform with temperature changes, which is beneficial to the contact between the deformation portion 21 and the contact portion 22 to quickly transmit the signal.

[0062] It should be noted that, as the temperature is higher, the deformation of the deformation portion 21 is more serious, so as to form contact with the contact portion 22, so that the first electrical wire 23 and the second electrical wire 24 are electrically connected; as the temperature decreases, the deformation of the deformation portion 21 is restored, and at this time, the deformation portion 21 is disconnected from the contact portion 22, so that the first electrical wire 23 and the second electrical wire 24 are disconnected.

[0063] Reference Figure 1 and Figure 2 It is understood that the combustion chamber 3 includes an outer shell 31, which has a mounting wall 311 and side walls 3111 arranged on both sides of the mounting wall 311, and the deformation portion 21 is arranged at an interval from the mounting wall 311 and extends between the two side walls 3111 to form an insulating space 32 with the mounting wall 311.

[0064] In this embodiment, the setting of the outer shell 31 is conducive to preventing the heat of the combustion chamber 3 from being directly discharged into the environment and causing discomfort to the human body; the spacing arrangement of the deformation portion 21 and the mounting wall 311 is conducive to reducing and alleviating the heat transferred from the combustion chamber 3 to the outer shell 31, that is, it is conducive to reducing the temperature of the outer shell 31; the extension of the deformation portion 21 between the two side walls 3111 is conducive to increasing the spacing space, that is, the insulation space 32, and further reducing the temperature of the outer shell 31.

[0065] Reference Figure 2 It is understood that the deformation portion 21 includes a first plate body 211 and a second plate body 212, the lower end 2112 of the second plate body 212 is overlapped with the first plate body 211, the upper end 2111 of the second plate body 212 is separable from the first plate body 211, and the expansion coefficient of the second plate body 212 is greater than the expansion coefficient of the first plate body 211; the first plate body 211 is used to connect with the outer shell 31 of the combustion chamber 3, and the second plate body 212 is used to contact with the contact portion 22.

[0066] In this embodiment, the lower end 2112 of the second plate body 212 overlaps with the first plate body 211, which helps prevent the second plate body 212 from separating from the first plate body 211 and causing blockage in the combustion chamber 3. The upper end 2111 of the second plate body 212 can be separated from the first plate body 211, which helps connect the deformation part 21 with the contact part 22 when the temperature rises. The expansion coefficient of the second plate body 212 is greater than the expansion coefficient of the first plate body 211, which helps better fix the deformation part 21 on the mounting wall 311 of the outer shell 31. The first plate body 211 is connected to the outer shell 31 of the combustion chamber 3, and the second plate body 212 is in contact with the contact part 22. Such a structure allows the signal to be quickly transmitted between the outer shell 31 and the radiator 4, thereby improving the cooling efficiency.

[0067] It should be noted that the second plate body 212 is separable from the upper end 2111 of the first plate body, and the lower end 2112 is overlapped so that the second plate body 212 is in contact with the contact portion 22 while being fixed to the mounting wall 311 through the first plate body 211, and the structural design is ingenious and simple.

[0068] Reference Figure 2 It is understood that the contact portion 22 is bent, and the contact portion 22 includes a fixed position 221 and a contact position 222. The fixed position 221 is horizontally arranged at the bottom of the radiator 4, and the contact position 222 is vertically located in the combustion chamber 3. When the deformation portion 21 deforms with temperature changes, the second plate body 212 contacts the contact position 222 to make the first electrical line 23 and the second electrical line 24 electrically conductive.

[0069] In this embodiment, the contact portion 22 is bent so that the contact portion 22 can be fixed on the radiator 4 and can contact the second plate body 212. The fixing position 221 is horizontally arranged at the bottom of the radiator 4 so that the fixing area is increased and the fixing effect is good; the contact position 222 is vertically located in the combustion chamber 3, so it is arranged close to the second plate body 212, which is conducive to contact with the second plate body 212. The vertical arrangement also facilitates disconnection from the second plate body 212, which is conducive to improving the sensitivity of the temperature protection component 2.

[0070] It should be noted that, since the first plate 211 contacts the contact portion 22 when deformed near the middle of the cavity 312 , the connection position 221 should be set near the middle of the cavity 312 rather than at the edge of the cavity 312 near the first plate 211 .

[0071] Reference Figure 2 It is understood that the upper end 2111 of the first plate body 211 is inverted U-shaped, and the upper end 2111 of the first plate body 211 is provided with a first connecting position 21111, the first connecting position 21111 is connected to the inner side of the mounting wall 311 of the combustion chamber 3, and the lower end 2112 of the first plate body 211 extends to the lower part of the combustion chamber 3.

[0072] In this embodiment, the upper end 2111 of the first plate body 211 is in an inverted U-shape, which is conducive to forming an insulating space 32 between the deformation portion 21 and the outer shell 31, reducing the heat transferred from the combustion chamber 3 to the outer shell 31, that is, it is conducive to reducing the temperature of the outer shell 31; the lower end 2112 of the first plate body 211 extends to the lower part of the combustion chamber 3 to increase the insulating space 32, further reducing the heat transferred from the combustion chamber 3 to the outer shell 31, and further reducing the temperature of the outer shell 31.

[0073] It should be noted that the first connection position 21111 is screwed to the inner side of the mounting wall 311 of the combustion chamber 3, and the screw mounting is only a preferred structural setting method, but in other alternative embodiments, the screw mounting can also be set to any structure that is applicable thereto.

[0074] It should also be noted that the inverted U-shaped first plate body 211 is only a preferred structural setting method, but in other alternative embodiments, the first plate body 211 can also be set to any shape that is applicable thereto, such as an arc shape.

[0075] Reference Figure 2 It is understood that the second plate 212 is closer to the cavity 312 of the housing 31 , and when the deformation portion 21 deforms with temperature changes, the second plate 212 is closer to the middle of the cavity 312 of the housing 31 .

[0076] In this embodiment, the second plate 212 is closer to the cavity 312 of the outer shell 31 so as to be in contact with the heat in the combustion chamber 3 in a more timely manner, which is beneficial to improving the cooling efficiency of the temperature protection component 2. The closer the second plate 212 is to the middle of the cavity 312 of the outer shell 31, the higher the heat it contacts, the more timely the contact with the contact part 22, and the faster the temperature of the outer shell 31 can be reduced.

[0077] It should be noted that before the deformation portion 21 is deformed to the point where it can block the combustion chamber 3 , the temperature protection component 2 will lower the temperature of the combustion chamber 3 to restore the deformation of the deformation portion 21 .

[0078] Reference Figure 2 and Figure 3 It is understood that the second electrical wire 24 is connected to the lower end 2112 of the first plate 211 or the lower portion of the second plate 212 , and the first electrical wire 23 is connected to the heat sink 41 or the contact portion 22 of the radiator 4 .

[0079] In this embodiment, since the lower end 2112 of the second plate body 212 overlaps with the first plate body 211, the connection between the second electrical line 24 and the lower end 2112 of the first plate body 211 or the lower part of the second plate body 212 is conducive to the second electrical line 24 receiving a stronger signal; the first electrical line 23 is connected to the heat sink 41 or the contact part 22 of the radiator 4 to adapt to different connection conditions.

[0080] Reference Figure 2 It is understood that temperature protection components 2 are provided on opposite sides of the combustion chamber 3 .

[0081] In this embodiment, the two relatively sides are the side close to the user and the side far away from the user when the gas water heater 1 is in use. The temperature protection components 2 are provided on both sides to improve the overall heat reduction effect of the combustion chamber 3.

[0082] It should be noted that combustion may not necessarily occur on one side of the combustion chamber 3 , but combustion may occur on both sides independently or simultaneously.

[0083] Reference Figure 1 and Figure 2 The temperature protection assembly 2 also includes an electric controller, and the first electric wire 23 and the second electric wire 24 are both electrically connected to the electric controller.

[0084] In this embodiment, the first electrical equipment line 23 and the second electrical equipment line 24 are both electrically connected to the electric controller so that the first electrical equipment line 23 and the second electrical equipment line 24 are electrically connected and can transmit signals to the electric controller.

[0085] It should be noted that the electric controller can control the magnitude of the current of the gas water heater 1 .

[0086] The utility model also provides a gas water heater 1, which is characterized in that it includes the above-mentioned temperature protection component 2, gas proportional valve and fan 6, the temperature protection component 2 includes an electric controller, and the gas proportional valve and fan 6 are electrically connected to the electric controller respectively.

[0087] In this solution, the gas proportional valve can control the flow rate of the gas to control the temperature of the outer shell 31 , and the fan 6 can dissipate heat from the combustion chamber 3 , which is beneficial to reducing the temperature of the outer shell 31 .

[0088] It should be noted that after the first electrical wiring 23 and the second electrical wiring 24 are electrically connected, the electric controller feeds back an electrical signal to the gas proportional valve and the fan 6 to change the current of the gas proportional valve and the current of the fan 6 .

[0089] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
