Special water dispenser for railway trains

Abstract

The invention provides a special water dispenser for railway trains, which comprises a water purifying filter and a water heater in liquid communication with the same, as well as an electrical controldevice for control use. The water purifying filter comprises a filter component, an incoming water pipeline, a purified water outflow pipeline, a pipeline stored water emptying device for emptying stored water in an internal pipeline of the water purifying filter, an insulation layer for freezing prevention, and a first electric heating element. The water heater comprises a boiling container, a water delivery pipeline, a second electric heating element for heating the boiling container, a water flow control device for controlling the water flow injected into the boiling container, and an emptying device connected with the purified water outflow pipeline of the water purifying filter and the boiling container of the water heater and used for emptying stored water as required. A waterproofanti-explosion housing is arranged outside the boiling container and the second electric heating element; the electrical control device comprises a controller with a GPS (global positioning system) module for providing altitude information. The special water dispenser for railway trains helps solve the problem that an existing device has poor ultralow temperature freezing prevention and fireproofand anti-explosion capacities and the problem of safety water supply at high altitudes.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a special water dispenser for railway trains. Background technique [0002] The effective supply of drinking water for trains is an indispensable part of train operation. With the development of society and the continuous improvement of living standards, people's requirements for the quality of drinking water provided by trains, especially bullet trains and high-speed rails are also increasing. For this reason, the drinking water dispenser or similar devices that provide drinking water on the train are usually made up of two parts connected to each other at present, one is the water purification filter device at the front end, and its second is the electric water heater at the rear end, and the water purification filter device at the front end is used To filter the drinking water source on the train, the electric water heater is used to heat the clean water output by the water purification f...

Problems solved by technology

This type of existing train drinking water device can generally meet the needs of use under ordinary conditions. However, because the region and environment of train operation often change greatly, there are the following problems in the existing train drinking water device: one, the railway department requires that the equipment on the train Drinking water devices can be effectively used in the temperature range of -40°C to 40°C, and will not freeze within 12 hours at an ambient temperature of -40°C. However, the existing drinking water devices for trains are difficult to meet the above requirements. Under the extremely low temperature environment, the existing drinking water device cannot be effectively drained due to the internal water storage, and it is very easy to freeze and cannot be used normally or even cracked and damaged. The impact of per
