[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0041] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0042] Heat pump equipment such as heat pump air conditioners and heat pump water heaters produce condensate during operation. This condensate drips onto the chassis of the heat pump equipment and is discharged to the outside. In low-temperature environments, the condensate in the chassis is prone to freezing, causing blockage of the drain outlet and preventing proper drainage, thus affecting the normal operation of the heat pump equipment.

[0043] In related technologies, heating elements such as heating copper pipes are installed inside the chassis to heat ice blocks when they freeze, enabling rapid de-icing and preventing blockage of the chassis's drain outlets. However, existing heating elements are mainly connected to the chassis via multiple clips, requiring individual clipping for fixation, which is inconvenient and affects assembly efficiency.

[0044] Therefore, referring to Figures 1 to 11 As shown, the first aspect of this utility model provides a chassis assembly for use in heat pump equipment, which includes heat pump air conditioners, heat pump water heaters, and other equipment.

[0045] Generally speaking, a heat pump device includes at least components such as a heat exchanger 400, pipes, a pump body, and a fan. The chassis assembly serves as a support platform for the installation and positioning of components such as the heat exchanger 400, pipes, pump body, and fan of the heat pump device. At the same time, the chassis assembly is also used to collect the condensate generated during the operation of the heat pump device.

[0046] The specific structure of the chassis components will be described in detail below.

[0047] It is understood that the chassis assembly includes the chassis body 100, the fastener 200, and the heating element 300.

[0048] Reference Figure 1 and Figure 2 As shown, it can be understood that the chassis body 100 can be a metal disc, a combination of a metal disc and a plastic disc, etc. In this embodiment, the chassis body 100 is configured as a combination of a metal disc and a plastic disc. Specifically, the chassis body 100 includes a first disc 110 and a second disc 120. The first disc 110 is a sheet metal part, i.e., the first disc 110 is a metal disc, and the second disc 120 is a plastic part, i.e., the second disc 120 is a plastic disc. The second disc 120 is disposed below the first disc 110 and covers the bottom of the first disc 110. Typically, a thermal insulation layer 130 is also provided between the first disc 110 and the second disc 120. The thermal insulation layer 130 is usually made of EPP foam material (i.e., polypropylene foam resin), which has good heat insulation properties.

[0049] The heat exchanger 400, pump body, fan, and other components are connected and fixed to the first plate 110. Since the first plate 110 is a sheet metal part, its high structural strength ensures the installation stability of the heat exchanger 400, pump body, fan, and other components. By incorporating the second plate 120 and insulation layer 130, the thermal resistance between the inner side (facing the inside of the heat pump equipment) and the outer side (facing the outside of the heat pump equipment) of the chassis body 100 is significantly reduced due to the lower thermal conductivity of plastic parts compared to sheet metal parts, combined with the insulation layer 130. Therefore, in high-temperature and high-humidity external environments, the risk of condensation on the bottom wall of the chassis body 100 is effectively reduced. In low-temperature external environments, the risk of condensation freezing on the inner side of the chassis body 100 is also effectively reduced.

[0050] Reference Figure 2 As shown, the chassis body 100 is provided with a water collection cavity 140, which is used to collect condensate dripping from the heat exchanger 400. Specifically, the water collection cavity 140 is located on the first plate 110, and the opening of the water collection cavity 140 faces upward, that is, the water collection cavity 140 is located on the side of the first plate 110 away from the second plate 120. Since the first plate 110 is a sheet metal part, a recess can be formed on the first plate 110 through a stamping process, and the recess is the water collection cavity 140. It is easy to understand that the chassis body 100 is provided with a drain outlet 143, which penetrates the bottom wall of the water collection cavity 140, and also penetrates the first plate 110, the insulation layer 130, and the second plate 120. The heat exchanger 400 is located above the water collection chamber 140 so that the condensate produced by the heat exchanger 400 can drip accurately into the water collection chamber 140, so as to collect the condensate and discharge it to the outside of the heat pump equipment through the drain port 143.

[0051] Reference Figure 5 As shown, it can be understood that the fastener 200 is a sheet metal part, which can be obtained through stamping and forming processes, and is easy to process. Specifically, the fastener 200 is provided with a receiving groove 230, which is used to install the heating element 300.

[0052] Reference Figure 3 and Figure 4 As shown, the heating element 300 is an electric heating element, such as a heating wire or electric heating band, which generates a large amount of heat when energized. Typically, the heating element 300 includes a heating section and a connecting end. The heating section is fixedly installed within the receiving groove 230, and the connecting end extends from the receiving groove 230 to the outside of the fixing member 200; that is, a portion of the structure of the heating element 300 is installed within the receiving groove 230. The connecting end of the heating element 300 is used for electrical connection with the power supply system of the heat pump equipment to supply power to the heating element 300.

[0053] Of course, in other embodiments, the heating element 300 can be fixedly installed entirely within the receiving groove 230, that is, both the heating part and the connecting end of the heating element 300 are located within the receiving groove 230. By introducing the power supply system wires of the heat pump device from the outside of the fixing member 200 into the receiving groove 230 and electrically connecting them to the connecting end of the heating element 300, power can be supplied to the heating element 300.

[0054] Reference Figure 1 and Figure 2 As shown, it can be understood that the fixing member 200 is installed in the water collection cavity 140 and fixedly connected to the chassis body 100, that is, the fixing member 200 is fixedly connected to the first plate body 110. Specifically, the opening of the receiving groove 230 faces the bottom wall of the water collection cavity 140, that is, the opening of the receiving groove 230 is arranged downwards, so that the heating element 300 can be exposed on the bottom wall of the water collection cavity 140 through the opening of the receiving groove 230, thereby reducing the thermal resistance between the heating element 300 and the first plate body 110. When the condensate in the water collection cavity 140 freezes due to low temperature, the heat generated by the heating element 300 can be quickly conducted to the ice, causing the ice to melt quickly, achieving rapid de-icing, and avoiding blockage of the drain outlet 143 and affecting drainage.

[0055] Therefore, when installing the heating element 300, the heating element 300 is first fixedly installed into the receiving groove 230 of the fixing element 200, and then the heating element 300 and the fixing element 200 are installed together into the water collection cavity 140 of the chassis body 100, and the fixing element 200 is fixedly connected to the chassis body 100. This allows the heating element 300 to be quickly installed into the chassis body 100, which is convenient and helps to improve assembly efficiency.

[0056] It is easy to understand that since the heating element 300 is set in the receiving groove 230 of the fixing element 200, and the fixing element 200 is a sheet metal part, when the heating element 300 generates heat, the heat of the heating element 300 is conducted to the bottom wall of the water collecting cavity 140 through the groove opening of the receiving groove 230, and also conducted to the outside of the fixing element 200 through the fixing element 200. This can make the heat distribution more uniform to a certain extent, which is conducive to heating the ice on the outside of the fixing element 200 and achieving rapid de-icing.

[0057] It is easy to understand that, since the heating element 300 is disposed within the receiving groove 230 of the fixing member 200, the fixing member 200 separates the heating element 300 from other components within the heat pump equipment (such as the heat exchanger 400, pump body, etc.), preventing direct contact between the heating element 300 and these other components. Therefore, the design requirements for the heat resistance and flame retardancy of these other components can be reduced, which is beneficial for cost reduction. Furthermore, the fixing member 200 covers the heating element 300, preventing the heating element 300 from being scratched and damaged.

[0058] Reference Figure 1 As shown, it can be understood that the combination of the fixing element 200 and the heating element 300 is located directly below the heat exchanger 400. Since the condensate in the water collection chamber 140 mainly drips from the heat exchanger 400, by positioning the combination of the fixing element 200 and the heating element 300 directly below the heat exchanger 400, ice can be quickly removed when icing occurs, avoiding the disadvantage of damage to the heat exchanger 400 due to icing.

[0059] It is understood that in this embodiment, the heating element 300 is configured as an electric heating strip. The electric heating strip is flexible and easy to bend, allowing the heating element 300 to be bent and arranged according to the shape of the receiving groove 230, resulting in good adaptability and easy installation. Generally, the outer side of the electric heating strip is wrapped with heat-resistant rubber, which helps protect the electric heating strip, prevents short circuits, and provides good corrosion resistance.

[0060] It is easy to understand that, in this embodiment, since the heating element 300 is configured as a flexible electric heating strip, by placing the heating element 300 in the receiving groove 230 of the fixing member 200, the heating element 300 can be arranged neatly, avoiding affecting other components of the heat pump equipment.

[0061] Reference Figures 3 to 5As shown, the fastener 200 includes a main body 210 and an extension portion 220. The main body 210 is annular, and the extension portion 220 is connected to one radial side of the main body 210 and protrudes outward from the main body 210. The main body 210 is generally rectangular in shape and has a first groove segment 231 arranged circumferentially along the main body 210, that is, the first groove segment 231 is an annular groove. The main body 210 includes a top plate 211 and two side plates 212 connected to the same side of the top plate 211 along the thickness direction. Both the top plate 211 and the two side plates 212 are annular. One side plate 212 is connected to the inner periphery of the annular top plate 211, and the other side plate 212 is connected to the outer periphery of the annular top plate 211. Both side plates 212 are located below the top plate 211, that is, the cross-section of the main body 210 is generally inverted U-shaped. Thus, a first groove segment 231 is defined between the top plate 211 and the two side plates 212, and the opening of the first groove segment 231 faces downward.

[0062] Reference Figures 3 to 5 As shown, it can be understood that the cross-section of the lead-out portion 220 is also inverted U-shaped, which will not be described in detail here. The lead-out portion 220 is connected to the side plate 212 on the outer side of the main body portion 210. The lead-out portion 220 is provided with a second groove segment 232, and the groove opening of the second groove segment 232 is also arranged downward. One end of the second groove segment 232 is connected to the first groove segment 231, and the other end is provided with an outlet 234. The first groove segment 231 and the second groove segment 232 combine to form a receiving groove 230. That is, the receiving groove 230 includes the first groove segment 231 provided in the main body portion 210 and the second groove segment 232 provided in the lead-out portion 220.

[0063] Reference Figures 3 to 5 As shown, it can be understood that the heating element 300 is accommodated in the first groove segment 231 and the second groove segment 232, and both ends (i.e., the connecting ends) of the heating element 300 are led out from the outlet 234 to the outside of the fixing element 200.

[0064] Typically, heat exchanger 400 includes heat dissipation fins. Since the combination of fixing member 200 and heating element 300 is located below heat exchanger 400, fixing member 200 is provided with lead-out portion 220, which extends from directly below heat exchanger 400 to the outside of heat exchanger 400 and covers part of the structure of heating element 300 near the connection end. This allows fixing member 200 to cover the structure of heating element 300 located directly below heat exchanger 400, thereby effectively reducing the risk of heating element 300 being scratched by heat dissipation fins of heat exchanger 400, protecting heating element 300 and preventing short circuits.

[0065] Meanwhile, since the main body 210 is annular, the heating element 300 is arranged in annular shape in the water collection cavity 140, which can increase the de-icing range and make the heat distribution more uniform, which is conducive to rapid de-icing.

[0066] Of course, in other embodiments, the shape of the main body 210 can also be V-shaped, Z-shaped, etc., and correspondingly, the shape of the first groove segment 231 matches the shape of the main body 210. The shapes of the main body 210 and the first groove segment 231 are not specifically limited here.

[0067] Reference Figure 5 As shown, it can be understood that since the first groove segment 231 is an annular groove, the first groove segment 231 has at least four bends. At the bends of the first groove segment 231, the groove wall of the first groove segment 231 is configured with rounded corners 233, so that the groove wall of the first groove segment 231 has an arc transition at the bend, thereby avoiding scratching the heating element 300 and avoiding short circuits.

[0068] Typically, there is a bend at the connection between the first groove segment 231 and the second groove segment 232. Similarly, the groove wall at the connection between the first groove segment 231 and the second groove segment 232 is also configured with rounded corners 233, so that the groove wall of the first groove segment 231 and the groove wall of the second groove segment 232 are curved, thereby avoiding scratching the heating element 300 and preventing short circuits.

[0069] Reference Figure 4 As shown, it can be understood that the fastener 200 also includes a plurality of first limiting elements 240. Specifically, the first limiting elements 240 are connected to the side plate 212 of the main body 210 and located at the opening of the first groove segment 231. The plurality of first limiting elements 240 are arranged at intervals along the circumference of the first groove segment 231, that is, the plurality of first limiting elements 240 are arranged at intervals along the length direction of the first groove segment 231. Each first limiting element 240 covers a portion of the opening of the first groove segment 231, so that the first limiting element 240 can prevent the heating element 300 from disengaging from the fastener 200 through the opening of the first groove segment 231.

[0070] Similarly, a first limiting element 240 is also provided at the opening of the second groove segment 232, which will not be described in detail here. In this way, the first limiting element 240 can prevent the heating element 300 from detaching from the fixing member 200 through the opening of the second groove segment 232. That is to say, multiple first limiting elements 240 are provided at the opening of the receiving groove 230, and the first limiting elements 240 abut against the heating element 300. Therefore, the multiple first limiting elements 240 cooperate to prevent the heating element 300 from detaching from the receiving groove 230 as a whole, so that the heating element 300 is securely installed on the fixing member 200.

[0071] The following describes the specific structure of the first limiting element 240 at the opening of the first slot 231 as an example. The specific structure of the first limiting element 240 at the opening of the second slot 232 can be referred to the structure of the first limiting element 240 at the opening of the first slot 231.

[0072] Reference Figure 5 As shown, the first limiting element 240 includes a bent portion 241 and a limiting portion 242, both of which are plate structures. One end of the bent portion 241 is connected to the side plate 212, that is, one end of the bent portion 241 is connected to one side wall of the receiving groove 230, and the limiting portion 242 is connected to the other end of the bent portion 241. Generally speaking, the width of the bent portion 241 is smaller than the width of the limiting portion 242. On the one hand, this makes the bent portion 241 easier to bend and convenient to operate; on the other hand, the larger area of ​​the limiting portion 242 helps to improve the installation stability of the heating element 300.

[0073] It is easy to understand that before the heating element 300 is installed onto the fixing member 200, the bent portion 241 and the limiting portion 242 are in an unfolded state, so that the entire opening of the receiving groove 230 is exposed, facilitating the installation of the heating element 300. After the heating element 300 is installed into the receiving groove 230, the bent portion 241 is bent, and the limiting portion 242 covers part of the opening of the receiving groove 230 and abuts against the heating element 300, thus limiting the heating element 300 and making operation convenient. Generally speaking, the limiting portion 242 abuts against the heating element 300 to fix the heating element 300 and improve the installation stability of the heating element 300.

[0074] In other embodiments, the first limiting element 240 may also be a limiting strip, a limiting buckle 1411, or other structural forms.

[0075] Reference Figure 9 and Figure 10 As shown, it can be understood that in some embodiments, the first limiting element 240 further includes first flanges 243 connected to both ends of the limiting portion 242. Specifically, two first flanges 243 are connected to both ends of the limiting portion 242 along the length of the first groove segment 231. The first flanges 243 are also plate structures, and the first flanges 243 are bent downwards, that is, the first flanges 243 are bent in a direction away from the receiving groove 230. Therefore, the two ends of the limiting portion 242 are arc-shaped transition structures without any included angle, thereby effectively preventing the limiting portion 242 from scratching the heating element 300 and preventing short circuits.

[0076] Reference Figure 9 and Figure 10As shown, it can be understood that the first flange 243 has two corners at one end away from the limiting part 242. The two corners are configured as a first transition surface 2431, which can be an arc surface (i.e., the corners are rounded 233) or other curved surfaces. Therefore, during the process of installing the heating element 300 into the receiving groove 230 of the fixing member 200, the first flange 243 can be prevented from scratching the heating element 300, thereby protecting the heating element 300 and preventing short circuits.

[0077] Reference Figure 9 and Figure 10 As shown, it can be understood that the fastener 200 is provided with at least one clearance groove 250. Specifically, the clearance groove 250 is provided on the side plate 212 of the main body 210 and located at the lower end of the side plate 212. In this embodiment, there are two clearance grooves 250, and the two clearance grooves 250 are located at the end of the main body 210 near the lead-out portion 220. The clearance groove 250 penetrates the side plate 212 of the main body 210 (i.e., the groove wall of the receiving groove 230), and the groove opening of the clearance groove 250 is arranged downward, that is, the groove opening of the clearance groove 250 faces the same direction as the groove opening of the receiving groove 230. The two first limiting elements 240 are respectively connected to the bottom wall surface of the two clearance grooves 250, that is, the end of the bent portion 241 away from the limiting portion 242 is connected to the bottom wall surface of the clearance groove 250. On the one hand, the clearance groove 250 can be understood as a process groove, which facilitates the processing of the first limiting element 240. On the other hand, by setting the clearance groove 250, the limiting part 242 of the first limiting element 240 is located in the receiving groove 230 after bending. This is beneficial for the limiting part 242 to press the heating element 300, making the heating element 300 installed firmly and reliably. At the same time, it can prevent the limiting part 242 and the first flange 243 from protruding out of the groove opening of the receiving groove 230 and hindering the installation of the fixing element 200 to the chassis body 100, thereby making the fixing element 200 and the heating element 300 installed firmly. The number of clearance grooves 250 can also be three, four or more.

[0078] It is easy to understand that, for the first limiting element 240 connected to the lower end face of the side plate 212 of the main body 210, the limiting part 242 and the first flange part 243 should be pressed into the receiving groove 230 as much as possible.

[0079] Reference Figure 9 and Figure 10 As shown, it can be understood that the wall surface at the opening of the clearance groove 250 is configured as a second transition surface 251. That is, the inner wall surface of the clearance groove 250 and the lower end surface of the side plate 212 are connected through the second transition surface 251. Similarly, the second transition surface 251 can be an arc surface or other curved surface. Therefore, during the process of installing the heating element 300 into the receiving groove 230 of the fixing member 200, the side plate 212 can be prevented from scratching the heating element 300, thereby protecting the heating element 300 and preventing short circuits.

[0080] Reference Figures 3 to 5 As shown, or refer to Figure 8 and Figure 11 Understandably, since the fastener 200 is a sheet metal part, the heating element 300 is easily scratched at the edge of the outlet 234. Therefore, the fastener 200 also includes a second flange 221. Specifically, the second flange 221 is connected to the edge of the outlet 234, and the second flange 221 is bent outwards towards the second groove segment 232. This creates an arc-shaped structure at the edge of the outlet 234, preventing scratches to the heating element 300 and avoiding short circuits.

[0081] Reference Figure 4 and Figure 5 As shown, the fastener 200 also includes a second limiting element 215. The second limiting element 215 is a plate structure, located within the first groove segment 231 and connected to the groove wall of the first groove segment 231, and located on one side of the second groove segment 232. By setting the second limiting element 215, one side of the second groove segment 232 is blocked from the first groove segment 231.

[0082] Reference Figure 4 and Figure 5 As shown, it can be understood that the heating element 300 in this example is an electric heating strip. Both ends (i.e., the connecting ends) of the electric heating strip need to be connected to the power supply system's wires to supply power. To facilitate the connection between the connecting ends of the electric heating strip and the wires, the electric heating strip is usually folded into two parallel sections, with both ends located at the same end. Therefore, when installing the electric heating strip, the folded electric heating strip is arranged starting from the second limiting element 215, so that the end of the folded electric heating strip facing away from the connecting end abuts against the second limiting element 215. The electric heating strip is then arranged sequentially in the first slot section 231 and the second slot section 232, with the connecting end of the electric heating strip leading out from the outlet 234. This achieves the installation of the electric heating strip in the receiving slot 230. The folded electric heating strip improves the melting efficiency of the ice. Simultaneously, by setting the second limiting element 215, the second limiting element 215 can serve as an indicator of the starting position for installing the electric heating strip, facilitating worker installation and preventing incorrect installation, thus providing a foolproof function.

[0083] Reference Figure 9 and Figure 11As shown, it can be understood that in some other embodiments, the second limiting element 215 has two corners at one end facing the opening of the receiving groove 230, and the corners are configured as a third transition surface 2151. Similarly, the third transition surface 2151 can be an arc surface (i.e., the corners are rounded 233) or other curved surfaces. Therefore, during the process of installing the heating element 300 into the receiving groove 230 of the fixing member 200, the second limiting element 215 can be prevented from scratching the heating element 300, thereby protecting the heating element 300 and preventing short circuits.

[0084] Reference Figure 6 and Figure 7 As shown, the fastener 200 also includes a first fixing part 213 and a second fixing part 214, both of which are plate-shaped structures. Specifically, the first fixing part 213 and the second fixing part 214 are both connected to the side plate 212 (i.e., the groove wall of the receiving groove 230) of the main body 210 and are located on the upper side of the main body 210. The first fixing part 213 and the second fixing part 214 are coplanar with the top plate 211. That is, the first fixing part 213 and the second fixing part 214 are both located on the side of the main body 210 away from the groove opening of the first groove segment 231. The first fixing part 213 is located at one end of the main body 210, and the second fixing part 214 is located at the other end of the main body 210, that is, the first fixing part 213 and the second fixing part 214 are arranged at intervals, and the first fixing part 213 and the second fixing part 214 are both located on the inner side of the annular main body 210, making the overall structure of the fastener 200 more compact.

[0085] Reference Figure 6 and Figure 7 As shown, it can be understood that the chassis body 100 includes a first protrusion 141 and a second protrusion 142. Specifically, both the first protrusion 141 and the second protrusion 142 are disposed on the bottom wall of the water collection cavity 140 and protrude upwards, that is, both the first protrusion 141 and the second protrusion 142 are disposed on the first plate body 110. The first protrusion 141 and the second protrusion 142 are arranged at intervals and correspond one-to-one with the first fixing part 213 and the second fixing part 214, respectively. After the combination of the fixing member 200 and the heating member 300 is installed into the water collection cavity 140, the first fixing part 213 abuts against the upper end face of the first protrusion 141 and is fixedly connected to the first protrusion 141, and the second fixing part 214 abuts against the upper end face of the second protrusion 142 and is fixedly connected to the second protrusion 142. The fixed connection here can be a snap-fit ​​or screw fixation, etc., thereby realizing the fixed installation of the combination of the fixing member 200 and the heating member 300 on the chassis body 100, and the connection is stable and reliable.

[0086] Reference Figure 6 and Figure 7As shown, in this embodiment, the first fixing part 213 is provided with a locking hole 2131, and correspondingly, the upper end face of the first boss 141 is provided with a buckle 1411, which is a bent plate structure. The second fixing part 214 and the second boss 142 are respectively provided with coaxially arranged connecting holes, and the second fixing part 214 and the second boss 142 are fixedly connected by fasteners, such as screws and rivets. Therefore, when installing the fixing member 200, the buckle 1411 is inserted into the locking hole 2131 and engaged with the first fixing part 213, and then the fastener is inserted into the connecting hole between the second fixing part 214 and the second boss 142 and tightened, thus fixing the fixing member 200 to the chassis body 100. This is convenient and easy to install.

[0087] Reference Figure 2 and Figure 3 As shown, in some other embodiments, the first fixing part 213 and the first boss 141, and the second fixing part 214 and the second boss 142 are fixedly connected by fasteners, which will not be described in detail here.

[0088] It is easy to understand that, since the bottom wall of the water collection cavity 140 is provided with the first protrusion 141 and the second protrusion 142, the fasteners connected between the first fixing part 213 and the first protrusion 141, and the fasteners connected between the second fixing part 214 and the second protrusion 142 are far away from the bottom wall of the water collection cavity 140. To a certain extent, this can prevent the fasteners from being soaked in the condensate in the water collection cavity 140, thereby avoiding the disadvantage of the fasteners being corroded by water immersion and extending their service life.

[0089] In other embodiments, the number of fixing parts may be one, three, four or more, as long as the combination of fixing part 200 and heating part 300 is securely installed on the chassis body 100.
