Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as Figure 1-2 As shown, a water dispenser with a PTC heating element includes a water dispenser casing 1, water inlet and outlet pipes, and hot and cold water faucets. The inside of the water dispenser casing 1 is provided with a PTC heating element 2, and the PTC heating element 2 consists of a water inlet 2-1, an outlet The nozzle 2-2, the heating pipe 2-3 and the heating component 2-4 are formed. The heating pipeline 2-3 is formed by bending an integral aluminum pipe. The water outlet 2-1 is connected in parallel with the cold water faucet 5 and connected with the water inlet pipe 3 of the water dispenser, and the water outlet 2-2 is connected with the hot water faucet 6.

[0022] Such as Figure 1-2 Shown, the water dispenser with PTC heating element, the section of heating pipeline 2-3 is a kind of in rectangle, square or circle, is rectangle in the pres...

Abstract

The invention discloses a water dispenser with a PTC heating element, belonging to the technical fields of household appliances. The water dispenser comprises a water dispenser shell, water inlet and outlet pipelines, and cold water and hot water faucets, wherein the PTC heating element is arranged inside the water dispenser shell, and is composed of a water inlet, a water outlet, a heating pipeline and heating assemblies, the heating pipeline is formed by bending an integral aluminium pipe, the heating assemblies are arranged in the gaps of the heating pipeline, the water inlet and the cold water faucet are connected in parallel, and then connected with the water outlet pipeline of the water dispenser, and the water outlet is connected with the hot water faucet. The water dispenser is scientific in structure and clear in working principle, the heating assembly structure of the traditional water dispenser is improved, and the PTC heating element does not contact water, so that water and electricity separation is realized, the PTC heating element is stable in performance, has small possibility of aging, and is long in service life, and the thermal efficiency of a heating system is kept to be stable for a long term.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and relates to a water dispenser, in particular to a water dispenser with a PTC heating element. Background technique [0002] The current water dispenser device basically uses electric heating tubes and water channels to be arranged side by side. The structure is basically to install electric heating elements on the outside of the water channel. The electric heating elements are used to heat the metal tubes. The heat load on the surface of the electric heating elements is 10W~15W / cm 2 , and the thermal inertia is large, the start is slow, and the heat load on the surface of the electric heating element immersed in water will not exceed 0W / cm 2 . The thermal efficiency is only 57%, the electric power used is large, the stability is poor, and the node effect is poor. At present, the water dispensers on the market generally have the following problems: 1. The start-up time is long, t...
