Description

Technical Field

[0001] This utility model belongs to the technical field of household appliance accessories, and in particular relates to an energy-saving dishwasher heater. Background Technology

[0002] The dishwasher heater is one of the core components of a dishwasher, primarily improving cleaning effectiveness, sterilization, and drying efficiency by heating the water. Here is a detailed analysis of its specific functions: 1) The heater can raise the water temperature to 60-75℃. High-temperature water more effectively breaks down grease and food residue, making it especially suitable for cleaning heavily soiled Chinese tableware. The high-temperature water, combined with the high-pressure water flow from the spray arms, enhances the rinsing force, covering hard-to-reach areas and ensuring thorough cleaning. 2) When the water temperature reaches above 70℃, it can kill most common bacteria (such as E. coli and Staphylococcus aureus), making it suitable for families with infants or members with weakened immune systems. Some models achieve sterilization through a high-temperature rinsing stage, reducing the need for a separate sterilizing cabinet. The dishwasher heater not only ensures basic cleaning and sterilization needs but also promotes energy efficiency and intelligent features through technological upgrades.

[0003] Existing dishwasher heater designs based on heating tubes have shortcomings. Most of their heating tubes are directly in contact with the flange for heat conduction through welding. When the heating tube is energized, a significant amount of heat is conducted to the outside of the flange at the contact point.

[0004] In view of this, the inventors hoped to design an energy-saving dishwasher heater. Utility Model Content

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide an energy-saving dishwasher heater.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: This utility model provides an energy-saving dishwasher heater, including a heater mounting flange, an electric heating element, and a heat insulation bracket; The heater mounting flange includes an inner surface in contact with the liquid, an outer surface opposite to the inner surface, and an interface located at the boundary between the inner and outer surfaces. The heating element includes a heating section, a non-heating section, and an end. The heating section has an end connected to both sides via the non-heating section. The end of the heating element passes through the interface of the heater mounting flange and extends to the outer surface. The heat insulation bracket is disposed between the heating section of the electric heating tube and the inner surface of the heater mounting flange.

[0007] Furthermore, in the aforementioned energy-saving dishwasher heater, the interface material of the heater mounting flange is metal.

[0008] Furthermore, in the aforementioned energy-saving dishwasher heater, the heating section and non-heating section of the heating tube are parallel to each other with the heater mounting flange, and the end of the heating tube is perpendicular to each other with the heater mounting flange.

[0009] Furthermore, in the aforementioned energy-saving dishwasher heater, the heat insulation bracket is connected to the heating section of the electric heating tube by a snap-fit ​​connection.

[0010] Furthermore, in the aforementioned energy-saving dishwasher heater, the heat insulation bracket is connected to the inner surface of the heater mounting flange by riveting or welding.

[0011] Furthermore, in the aforementioned energy-saving dishwasher heater, the heat insulation bracket includes a fixed plate, a bottom support plate, and a top pressure plate. The fixed plate is provided with multiple sets of snap-fit ​​structures composed of the bottom support plate and the top pressure plate arranged side by side, and the positions of the bottom support plate and the top pressure plate in two adjacent snap-fit ​​structures are staggered.

[0012] Furthermore, in the aforementioned energy-saving dishwasher heater, the fixing plate portion serves as a connecting portion that connects to the inner surface of the heater mounting flange.

[0013] Furthermore, in the aforementioned energy-saving dishwasher heater, the bottom support plate can abut against the bottom end of the heating section in the electric heating tube, and the top pressure plate can abut against the top end of the heating section in the electric heating tube.

[0014] The beneficial effects of this utility model are: 1. This utility model provides an energy-saving dishwasher heater, which mainly consists of a heater mounting flange, an electric heating tube, and a heat insulation bracket. By adding a heat insulation bracket between the heating section of the electric heating tube and the inner surface of the heater mounting flange, the electric heating tube is not directly welded to the heater mounting flange. In this way, heat will not be directly dissipated into the air through the welded part, improving the energy utilization rate of the dishwasher heater, allowing more heat to directly heat the liquid, and very little heat to be dissipated.

[0015] 2. The heat insulation bracket of this utility model is reasonably designed, including a fixed plate, a bottom support plate and a top pressure plate. The fixed plate is provided with multiple sets of snap-fit ​​structures composed of bottom support plates and top pressure plates side by side. The positions of the bottom support plate and the top pressure plate in two adjacent snap-fit ​​structures are staggered. The heat insulation bracket is fixed at the snap-fit ​​position of the heating tube, which can improve the consistency of the product.
