Split type vacuum heat insulation water dispenser hot cylinder

Abstract

The invention discloses a split type vacuum heat insulation water dispenser hot cylinder. The hot cylinder comprises a threaded cover, a heat preservation cover and a hot cylinder body, the threaded cover presses an upper opening of the hot cylinder body, and the heat temperature cover is plugged in the upper opening of the hot cylinder body; the threaded cover is composed of a plastic cover and aprotection cover, and the protection cover sleeves the plastic cover; the heat temperature cover is composed of an upper cover and a lower cover, the lower cover is of a cup-shaped structure, a heating tube, a water inlet tube, a water outlet tube, a temperature measuring sleeve, a hot temperature measuring tube, a heat collection block and two burst temperature control devices are installed on the bottom surface of the lower cover, and a step is formed on the portion, close to the bottom surface, of the side wall of the lower cover. By means of the split type vacuum heat insulation water dispenser hot cylinder, the water dispenser hot cylinder adopts a split type structure, mass production and maintenance are convenient, the hot cylinder adopts a mode that the hot tube and the burst temperature control devices measure and control temperature and prevent dry boiling, and the defect is completely avoided that the vacuum hot cylinder needs to adopt electronic temperature control.

Description

technical field [0001] The invention relates to the field of water dispenser manufacturing, in particular to a split-type vacuum-insulated water dispenser hot cylinder. Background technique [0002] The main disadvantages of the existing vacuum insulated water dispenser heating cylinders include: 1. Adopt integral welding structure, that is, all parts such as water inlet pipes, water outlet pipes, and heating pipes are integrated with the heating cylinder body by welding. The advantage is that the possibility of water leakage is relatively small, and the disadvantage is that once the heating tube is damaged or the pipeline leaks, the entire heating cylinder can only be scrapped; 2. The electronic temperature measurement method is adopted, because the heat inside the vacuum insulation heating cylinder cannot be quickly conducted through the outer wall, Therefore, the traditional bimetallic sudden jump thermostat cannot be used, and the temperature can only be measured by inse...

[0002] The main disadvantages of the existing vacuum insulated water dispenser heating cylinders include: 1. Adopt integral welding structure, that is, all parts such as water inlet pipes, water outlet pipes, and heating pipes are integrated with the heating cylinder body by welding. The advantage is that the possibility of water leakage is relatively small, and the disadvantage is that once the heating tube is damaged or the pipeline leaks, the entire heating cylinder can only be scrapped; 2. The electronic temperature measurement method is adopted, because the heat inside the vacuum insulation heating cylinder cannot be quickly conducted through the outer wall, Therefore, the traditional bimetallic sudden jump thermostat cannot be used, and the temperature can only be measured by inserting the electronic temperature sensor through the temperature measuring sleeve welded on the body of the thermal cylinder, so that a DC power supply and an electronic circuit must be equipped to complete the temperature measurement. 3. Based on the above reasons, it is impossible to install a bimetal sudden jump thermostat on the body of the heat cylinder to prevent the heat from burning dry, so that the heat can only be The bottom of the tank is changed to a single-layer structure to install the anti-dry thermostat, which will increase the heat dissipation surface of the heat tank and greatly reduce the effect of vacuum insulation
