Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and specifically relates to a water purifier heating element that is compact in structure, easy to maintain, and provides uniform heating. Background Technology

[0002] The heating element is the core component of a water purifier that enables the heating function. To optimize space design, the water purifier casing is usually designed as a rectangular prism with narrow side dimensions. In this case, the heating element also needs to be adapted to be designed as a flatter rectangular prism. However, since the heating element has a certain extension length requirement, in this flat rectangular heating element, the heating element can only be installed on the side wall or bottom. This results in the need to disassemble the entire side cover during maintenance, which is cumbersome. In addition, this type of structure has low space utilization in a narrow casing and is prone to uneven heating problems such as local overheating.

[0003] Existing heating elements often rely on a single probe for water level control, which cannot achieve precise, staged heating and may result in high heating energy consumption or large water temperature fluctuations. Furthermore, the inlet lacks a flow guide design, causing water to directly impact the heating area, potentially leading to noise or affecting heating efficiency. While some products have improved performance by adding insulation layers or optimizing pipe layouts, shortcomings such as inconvenient maintenance, inflexible water level control, and unreasonable heating element layouts still exist. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a water purifier heating element that is compact in structure, easy to maintain, and provides uniform heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water purifier heating element is provided, wherein the heating element is a box-type structure, a protective cover is provided on the rear wall of the heating element, the protective cover corresponds to the inspection port position on the rear panel of the water purifier, a heating tube extending into the interior of the heating element is provided on the protective cover, the heating tube is a side-bent structure extending from the rear wall of the heating element to the side wall of the heating element, the heating element is provided with an inlet and an outlet, and the heating tube is installed at a position lower than the outlet.

[0007] Furthermore, the heating tube includes an upper tube and a lower tube arranged vertically, and both the upper tube and the lower tube include a front-to-back extension portion and a lateral extension portion, which are transitioned by a corner.

[0008] Furthermore, the water inlet is located at the bottom of the heating element, and a baffle plate is provided at the water inlet.

[0009] Furthermore, the water baffle is an inverted cover structure.

[0010] Furthermore, the heating element is equipped with a temperature sensor and a water level probe, the water level probe comprising several probes for detecting different water levels.

[0011] Furthermore, the water level probes include low water level probes, high water level probes, and overflow water level probes.

[0012] Furthermore, a detachable probe mounting cover is provided on the top cover of the heating element, and the water level probe is mounted to the heating element through the probe mounting cover.

[0013] Furthermore, the heating element is provided with an overflow port; the bottom of the heating element is provided with a drain port; and the heating element is wrapped with an insulation layer.

[0014] Furthermore, the heating element is generally in the shape of a flat rectangular parallelepiped, meaning that the distance between the front and rear walls of the heating element is less than the distance between the left and right side walls.

[0015] Furthermore, the water outlet is connected to the hot water outlet of the water purifier via a heating element solenoid valve; the water purifier's water production pipeline is connected to the water inlet of the heating element via a heating element inlet solenoid valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0023] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings. Contents not explicitly described in the embodiments of this utility model are all prior art, and those skilled in the art can refer to existing conventional technical solutions for implementation.

[0024] like Figures 1 to 3 As shown, this embodiment provides a water purifier heating element. The heating element adopts a box-type structure with an overall flat rectangular shape. The distance between its front and rear walls is smaller than the distance between its left and right side walls to adapt to the narrow side layout of the water purifier casing. The heating element shell 8 is wrapped with an insulation layer 1, and integrates components such as a heating tube 13, a temperature sensor 10, water level probes (low water level probe 3, high water level probe 2, and overflow water level probe 4), and an overflow port 9. The heating element is provided with an inlet and an outlet 6.

[0025] The heating element 13 is designed as a side-bent structure extending from the rear wall of the heating element to the side wall. A protective cover 55 made of insulating material is provided at the installation position of the heating element 13 on the rear wall of the heating element. In this embodiment, the protective cover 55 is preferably detachable. Since the heating element 13 is connected to high voltage, the protective cover provides protection. The protective cover 5 corresponds to the inspection port on the rear panel of the water purifier for easy maintenance. One end of the side-bent heating element 13 is installed at the protective cover 5, and the other end extends into the interior of the heating element. Specifically, preferably, the heating element 13 includes an upper tube and a lower tube arranged vertically, connected to each other at their ends. Both the upper and lower tubes include a front-to-back extension portion and a lateral extension portion, which are transitioned by a corner. The installation position of the heating element 13 is preferably lower than the water outlet 6 to avoid dry burning and to ensure that the heating area is concentrated at the bottom, preventing unheated water from being directly discharged.

[0026] The structural design of the heating tube 13 reduces the dimensional requirements of the heating tube in the length direction, allowing the heating tube to be installed on the rear wall of the heating tank. This also allows the access port to be moved to the rear wall of the heating tank. Since the rear panel of the water purifier is very easy to disassemble and has a natural access port, it is beneficial for the maintenance of the heating tank. At the same time, the heating tube with this structure is less prone to uneven heating problems such as local overheating.

[0027] The water inlet is preferably located on the bottom plate 14 at the bottom of the heat tank, and a baffle plate 11 is provided above the water inlet. Figure 3 The water inlet is blocked by a baffle plate 11 to buffer the incoming water flow, reduce impact noise, and guide the water flow to distribute evenly. The baffle plate 11 is preferably as follows: Figure 3 As shown, the baffle plate 11 has an inverted cover structure, which includes front, rear, left, right and upper side walls. The lower ends of the left and right side walls are fixedly connected to the bottom plate 14 of the heat tank, and there is a gap between the lower ends of the front and rear walls and the bottom plate 14 of the heat tank.

[0028] The top cover 15 is equipped with a probe mounting cover 7. Low water level probe 3, high water level probe 2, and overflow water level probe 4 are mounted on the heating element through this cover. The three probes are used to detect different water level states. It should be noted that the number of probes in this invention is not particularly limited and can be set according to actual needs. A temperature sensor 10 is fixed to the inner wall of the heating element for real-time water temperature monitoring. In this embodiment, the heating element, by setting multiple water level probes in combination with a temperature sensor, provides a good foundation for achieving step-by-step heating. The probe mounting cover 7 is preferably detachably mounted on the upper opening of the heating element (e.g., fixed by a wing nut), so that the upper opening can be used as a cleaning port when needed.

[0029] Combined with step-by-step heating logic: heating is started when the water level reaches the low water level probe 3, and water continues to be added after the temperature reaches the target; heating is resumed when the water level reaches the high water level probe 2, until the water is filled to the overflow level probe 4, then the hot water tank inlet solenoid valve 18 is closed, water injection stops and the final heating is completed.

[0030] The bottom of the heating element is equipped with a drain outlet 12, which is connected to the heating element drain solenoid valve 20 for regular cleaning of accumulated sewage; the overflow outlet 9 is located on the upper part of the side wall to prevent overflow caused by excessive water level.

[0031] The heating element piping connection in this embodiment is as follows: Figure 4 As shown:

[0032] The water supply pipeline 21 is connected to the inlet via the heating tank inlet solenoid valve 18 and the check valve 19. The pure water produced by the water supply pipeline 21 can enter the heating tank through the inlet. The outlet 6 is connected to the hot water outlet 17 via the heating tank outlet solenoid valve 16, allowing hot water from the heating tank to flow out from the hot water outlet 17. The solenoid valve is controlled by a controller based on water level and temperature signals to achieve precise water injection and heating control.

[0033] This embodiment significantly improves heating efficiency by optimizing the heat tank structure, making maintenance more convenient and suitable for various compact water purification equipment.
