Description

Technical Field

[0001] This invention belongs to the field of smart toilet technology and relates to an instant-heating toilet seat. Background Technology

[0002] When using a smart toilet, the seat is a crucial component. To enhance the user experience, a heating element is installed inside the seat to heat it during use, making it more convenient in cold weather.

[0003] Heating wires require time to heat up, and for better heat transfer in the seat ring, existing designs typically use a three-layer multi-functional toilet seat ring, as disclosed in Chinese patent application [Authorization Announcement No.: CN208491954U]. This design includes a base plate, a partition, and an upper plate arranged sequentially from bottom to top. A heating wire is disposed between the upper plate and the partition, and a first sensor is disposed between the base plate and the partition. The first sensor includes a pressure sensor. A horizontal pressure-bearing part is disposed on the surface of the base plate, and a horizontal pressure-applying part is disposed on the lower surface of the partition corresponding to the pressure-bearing part. The pressure sensor is disposed between the pressure-bearing part and the pressure-applying part. The partition is connected to the base plate only through the pressure sensor, and the upper plate is connected only to the partition.

[0004] In the above structure, the pressure-applying part is placed on the pressure-bearing part of the partition, and the heating wire and the first sensor are arranged in layers. This allows the heating wire to be fully laid inside the toilet seat to achieve a good heating effect. The first sensor is located below the partition, and the wiring is also located below the partition, so it will not come into contact with the heating wire and avoid safety hazards. In actual use, the user needs to sit on the toilet seat. Relying solely on the heating wire, the heat generated by the heating wire is transferred to the upper plate. The upper plate has a certain thickness, which makes the heat transfer not so timely, thus affecting the heating effect of the toilet seat. In order to improve the heating effect, the power of the heating wire is usually increased. Increasing the power of the heating wire can indeed improve the heating effect, but it will increase the power consumption and increase energy consumption. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an instant-heating toilet seat ring. The technical problem this invention aims to solve is: how to address the issue that existing toilet seat rings, while improving heating efficiency, cannot guarantee the stability of the seat ring during use.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An instant heating seat ring, comprising an upper plate, a lower plate and a heating wire. The upper plate has an annular upper plate body. The heating wire is adhered to the lower surface of the upper plate. The inner and outer edges of the upper plate are respectively folded downwards to form an inner flanging and an outer flanging. The inner flanging and the outer flanging are both fixedly connected to the lower plate. It is characterized in that the instant heating seat ring further comprises a heat transfer aluminum plate. The heat transfer aluminum plate is located inside the solid of the upper plate. The heat transfer aluminum plate is annular. The middle part of the lower plate is bent upwards to form a supporting part close to the heating wire. A number of heat transfer holes are distributed on the heat transfer aluminum plate. The supporting part has a number of supporting columns arranged in one-to-one correspondence with the heat transfer holes and abutted against the lower surface of the upper plate. The thickness of the upper plate is 0.8 mm to 1.3 mm.

[0008] By arranging the heat transfer aluminum plate inside the solid of the upper plate, specifically, the heat transfer aluminum plate is formed by insert molding on the upper plate. In order to improve the insert molding effect between the heat transfer aluminum plate and the upper plate, a number of heat transfer holes are opened on the heat transfer aluminum plate to increase the contact area between the heat transfer aluminum plate and the upper plate, improve the stability, and at the same time can directly separate the heat transfer aluminum plate from the heating wire, without the need to set other insulating materials between the two, making the installation convenient. And due to the need to improve the heat transfer effect, this structure improves the heat transfer effect from three aspects. On the one hand, the thickness of the upper plate is set to be relatively thin to achieve rapid heat transfer. On the other hand, the heat transfer aluminum plate is formed by insert molding in the upper plate, and rapid heat transfer is achieved through the setting of the heat transfer aluminum plate. On the third hand, it is set on the supporting part. The supporting part is bent upwards and close to the heating wire, reducing the space between the upper plate and the lower plate. Under the condition of constant heat, the smaller the space, the higher the heat transfer effect. Through the above three aspects, the heat transfer effect is improved. And due to the relatively thin thickness of the upper plate, the structural strength of the upper plate is relatively low. The integral molding of the heat transfer aluminum plate and the upper plate can play a role in improving the strength of the upper plate. However, the setting of the heat transfer holes, although it can improve the stability after the upper plate and the heat transfer aluminum plate are formed, there will be a lower strength at the heat transfer holes of the heat transfer aluminum plate on the upper plate. Therefore, by setting supporting columns on the supporting part of the lower plate, a good supporting effect is provided for the upper plate, so that the above-mentioned instant heating seat ring can improve the heat transfer effect while providing stable support.

[0009] In the above-mentioned instant heating seat ring, the cross-section of the upper plate is in a "冂" shape, and the thickness of the supporting part is greater than the thickness of the upper plate.

[0010] The shape setting of the upper plate, on the one hand, improves the comfort of the user and does not reduce the contact area between the instant heating seat ring and the user. On the other hand, it is convenient for the integral molding of the heat transfer aluminum plate and the upper plate. And the thickness setting of the supporting part can provide stable support for the upper plate, ensuring the structural strength of the instant heating seat ring while improving the heat transfer effect.

[0011] In the aforementioned instant heating seat ring, the heat transfer aluminum plate has an L-shaped cross-section. The heat transfer aluminum plate includes a heat transfer wall arranged horizontally and a limiting wall arranged vertically. The heat transfer holes are distributed on the heat transfer wall and penetrate the heat transfer wall vertically. The limiting wall is arranged inside the outer wall of the upper plate.

[0012] The heat transfer wall can accurately conduct heat from the heating wire. The setting of the limiting wall can play a role in the initial positioning during the one-piece molding process. Since the user basically cannot touch this part, it is only necessary to improve its structural strength and processing stability.

[0013] In the aforementioned instant heating seat ring, the diameter of the support column is greater than or equal to the diameter of the heat transfer hole.

[0014] The size settings of the support column diameter and heat transfer hole diameter result in a larger contact area for the support column and better force transmission, which improves the stability of the instant heating seat while enhancing the heat transfer effect.

[0015] In the aforementioned instant heating seat ring, the cross-section of the lower plate is shaped like a "Z". Both the inner and outer edges of the lower plate protrude to form sealing protrusions. The inner side of each sealing protrusion has a limiting edge that is higher than the sealing protrusion. The inner surfaces of the outer and inner flanges are provided with limiting recesses into which the corresponding sealing protrusions can be inserted. The sealing protrusions are inserted into the limiting recesses and fixedly connected, and the outer surface of the limiting edge is in contact with the inner flange.

[0016] Since the support column needs to be located below some of the positioning holes, the installation accuracy requirement is high. The upper and lower plates are connected by embedding the sealing protrusion into the limiting recess and then heat-melting or by gluing. However, relying solely on the embedding method results in a large installation error. Therefore, limiting edges are set on the sealing protrusions. By having the limiting edges abut against the inner flange, both quick positioning and improved positioning accuracy can be achieved, resulting in higher installation accuracy between the upper and lower plates.

[0017] In the aforementioned instant heating seat ring, there is an installation gap between the side of the limiting recess of the outward flange and the outer side of the sealing protrusion.

[0018] The installation gap serves two purposes: it provides an airtight seal and also allows space for hot-melt plastics or adhesives to be placed.

[0019] In the aforementioned instant heating seat ring, multiple support strips are arranged horizontally or vertically on the bottom surface of the lower plate, and the two ends of the support strips are respectively connected to the inner ring and the outer ring of the lower plate.

[0020] The support bars enhance the structural strength of the lower plate.

[0021] In the aforementioned instant heating seat ring, rubber plugs are provided between the inner flange and the inner ring of the lower plate, and between the outer flange and the outer ring of the lower plate.

[0022] The rubber plug not only improves the sealing stability and elastic support between the upper and lower plates, but also further reduces the space between them, thus enhancing the heat transfer effect.

[0023] Compared with existing technologies, this instant-heating seat ring has the following advantages:

[0024] 1. This structure improves heat transfer efficiency in three ways. First, the upper plate is made thinner to achieve rapid heat transfer. Second, a heat-transfer aluminum plate is injection-molded into the upper plate, which facilitates rapid heat transfer. Third, the support section is bent upwards and close to the heating wire, reducing the space between the upper and lower plates. Under constant heat conditions, a smaller space results in higher heat transfer efficiency. These three aspects improve heat transfer efficiency. However, the thinner upper plate results in lower structural strength. The integral molding of the heat-transfer aluminum plate with the upper plate improves the upper plate's strength. While the heat transfer holes improve the stability of the upper plate and the heat transfer aluminum plate after molding, the upper plate may have lower strength at the heat transfer holes. Therefore, support columns are provided on the support section of the lower plate to provide better support for the upper plate, allowing the aforementioned instant heating seat to provide stable support while improving heat transfer efficiency.

[0025] 2. Since the support column needs to be located below some of the positioning holes, the installation accuracy requirement is high. The upper and lower plates are connected by embedding the sealing protrusion into the limiting recess and then heat-melting or by gluing. However, relying solely on the embedding method results in a large installation error. Therefore, limiting edges are set on the sealing protrusion. By abutting the limiting edge against the inner ring of the upper plate, both quick positioning and improved positioning accuracy can be achieved, resulting in higher installation accuracy between the upper and lower plates.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1 As shown, this instant heating seat includes an upper plate 1, a lower plate 2, and a heating wire 3. The upper plate 1 has an annular upper plate 11. The heating wire 3 is attached to the lower surface of the upper plate 1. The inner and outer edges of the upper plate 1 are folded downward to form an inner flange 11 and an outer flange 12, respectively. Both the inner flange 11 and the outer flange 12 are fixedly connected to the lower plate 2.

[0035] Specifically, such as Figure 1-6 As shown, the instant heating seat also includes a heat transfer aluminum plate 4. The upper plate 1 and the heat transfer aluminum plate 4 are injection molded together. The heat transfer aluminum plate 4 is located inside the solid of the upper plate 1. The heat transfer aluminum plate 4 is annular. The middle part of the lower plate 2 is bent upward to form a support part 21 that is close to the heating wire 3. A number of heat transfer holes 41a are provided on the heat transfer aluminum plate 4. The support part 21 has a number of support columns 22 that correspond one-to-one with the heat transfer holes 41a and abut against the lower surface of the upper plate 11. The thickness of the upper plate 11 is 0.8mm to 1.3mm. The diameter of the support column 22 is greater than or equal to the diameter of the heat transfer holes 41a.

[0036] The heat transfer aluminum plate 4 is formed by insert injection molding on the upper plate 1. In order to improve the insert injection molding effect between the heat transfer aluminum plate 4 and the upper plate 1, a number of heat transfer holes 41a are provided on the heat transfer aluminum plate 4 to increase the contact area between the heat transfer aluminum plate 4 and the upper plate 1 and improve stability. And since the heat transfer effect needs to be improved, this structure improves the heat transfer effect from three aspects. On the one hand, the thickness of the upper plate 1 is set to be relatively thin to achieve rapid heat transfer. On the other hand, the heat transfer aluminum plate 4 is formed by insert injection molding in the upper plate 1, and rapid heat transfer is achieved through the setting of the heat transfer aluminum plate 4. On the third hand, the support portion 21 is provided, and the support portion 21 is bent upward and close to the heating wire 3, reducing the space between the upper plate 1 and the lower plate 2. Under the condition of constant heat, the smaller the space, the higher the heat transfer effect. The heat transfer effect is improved through the above three aspects. And because the thickness of the upper plate 1 is set to be relatively thin, the structural strength of the upper plate 1 is relatively low. The integral molding of the heat transfer aluminum plate 4 and the upper plate 1 can play a role in enhancing the strength of the upper plate 1. However, the setting of the heat transfer holes 41a, although it can improve the stability after the upper plate 1 and the heat transfer aluminum plate 4 are molded, there will be a lower strength at the heat transfer holes 41a of the upper plate 1 in the heat transfer aluminum plate 4. Therefore, support columns 22 are provided on the support portion 21 of the lower plate 2 to provide better support for the upper plate 1, so that the above-mentioned instant heating seat ring can improve the heat transfer effect while providing stable support.

[0037] As Figure 4-6 shown, the cross-section of the upper plate 1 is in a "冂" shape, the thickness of the support portion 21 is greater than that of the upper plate 1, the cross-section of the heat transfer aluminum plate 4 is in an L shape, the heat transfer aluminum plate 4 includes a heat transfer wall 41 arranged obliquely in the horizontal direction and a limiting wall 42 arranged vertically, the heat transfer holes 41a are distributed on the heat transfer wall 41 and penetrate the heat transfer wall 41 vertically, and the limiting wall 42 is arranged inside the outer flanging 12.

[0038] As Figure 4 shown, the cross-section of the lower plate 2 is in a "几" shape, the inner and outer edges of the lower plate 2 both protrude to form sealing protrusions 23, and there are limiting stop edges 24 higher than the sealing protrusions 23 on the inner sides of the sealing protrusions 23. Limiting recesses 13 for the corresponding sealing protrusions 23 to be embedded are provided on the inner side walls of the outer flanging 12 and the inner flanging 11. The sealing protrusions 23 are embedded in the limiting recesses 13 and fixedly connected, and the outer side surface of the limiting stop edge 24 abuts against the inner flanging 11. There is an installation gap 5 between the side surface of the limiting recess 12 of the outer flanging 12 and the outer side surface of the sealing protrusion 23.

[0039] As Figure 3 and Figure 4 shown, a plurality of support bars 6 are arranged on the bottom surface of the lower plate 2 in the horizontal or vertical direction. The two ends of the support bars 6 are respectively connected to the inner circle and the outer circle of the lower plate 2. Rubber plugs 7 are provided between the inner flanging 11 and the inner circle of the lower plate 2 and between the outer flanging 12 and the outer circle of the lower plate 2.

[0040] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
