Abstract

The utility model relates to a hot water pot of an internal heating type cold-hot water drinker with an overflow preventing device. An electrical heating pipe is installed on a base of the heating pot. The electrical heating pipe and the base of the heating pot adopt a screwed connection. The upper part of a water inlet pipe is provided with an overflow preventing device which is composed of a float valve and a float valve cartridge, and the top of the heating pot is provided with a finite pressure valve and a pressure-sensitive switch which is installed in the transmitting pressure pipe. When the hot water pot of the utility model is adopted, the utility model can effectively prevent the boiling water in the pot and the steam entering the cold jug and better overcome the shortcomings of the prior art. The utility model has the advantages of low product cost, easy and safe use, easy cleanness and effective energy saving.

Description

The internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device

The utility model relates in a kind of cold and hot water drinking machine that is mainly used in various models, and the high-temperature water container as heating usefulness specifically refers to a kind of internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device.

The high-temperature water container of conduct heating usefulness in the cold and hot water drinking machine of existing various models, all adopt a kind of external jacket heated type container, promptly this container is one to be preset with the stainless steel airtight container of water inlet pipe and outlet pipe, establish the metal chuck of electric heating tube in outside container, being with, and by effect of heat insulation heat insulation layer parcel preferably, though the heating container of this structure can satisfy the needs of its function of use preferably, comparatively complexity, container two ends all can't be cleaned by welded seal, material cost is higher by special chuck parcel for its electric heating tube to exist structure; Particularly prior art does not possess the anti-overflow function, when temperature control is lacked of proper care, often causes boiling water by the anti-excessive cold water tank on it of water inlet pipe, influences its refrigeration; Steam is directly to be disposed to cold water tank by the aperture on the water inlet pipe in the jar in the existing heating tank, equally its refrigeration is caused certain influence, thus the valuable energy of waste.

The purpose of this utility model just is to provide a kind of internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device, to pass through its unique anti-overflow device and dismountable internal heat type heater, make it add thermal effect and function of use is improved significantly, prevented that effectively jar interior boiling water from entering cold water tank, thereby overcome the deficiencies in the prior art preferably, have simple in structure, product cost is low, easy to use, be easy to clean and the advantage of maintenance and energy savings.

The purpose of this utility model realizes in the following manner: a kind of internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device, mainly be by the heating tank that has water inlet pipe and outlet pipe, electric heating tube, heat-insulation layer and low level drainpipe are formed, it is characterized in that the electric heating tube device is on the heating tank base, take to be threaded between heating tank base and the heating tank, and be provided with resistant to elevated temperatures sealing ring in its contact position, end device also is provided with pressure limiting valve and the pressure-sensitive switch of device in pressure tube by the anti-overflow device of being made up of float valve and float valve tube at the top of heating tank on water inlet pipe.

Adopt the internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device of the present utility model, owing to adopted unique float-valve type anti-overflow device and dismountable internal heat type heater, make it add thermal effect and function of use is improved significantly, prevented that effectively jar interior boiling water and hot water and steam from entering cold water tank, avoided the unnecessary rising of the water temperature in the cold water tank, thereby overcome the deficiencies in the prior art preferably, have simple in structure, product cost is low, safety easy to use, heating tank is easy to clean and keep in repair and the advantage of energy savings effectively, is a kind of very desirable internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device.

Description of drawings:

Accompanying drawing is a kind of example structure schematic diagram of the present utility model.

Wherein: 1-heat-insulation layer, 2-heating tank, 3-float valve, 4-float valve tube, 5-water inlet pipe, 6-pressure tube, 7-pressure-sensitive switch, 8-pressure limiting valve, 9-outlet pipe, 10-sealing ring, 11-heating tank base, 12-electric heating tube, 13-low level drainpipe.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, the internal heat type cold and hot water drinking machine hot-water cylinder that has anti-overflow device of the present utility model, mainly form by the heating tank (2) that has water inlet pipe (5) and outlet pipe (9), electric heating tube (12), heat-insulation layer (1) and low level drainpipe (13), above-mentioned electric heating tube (12) device is on heating tank base (11), take to be threaded between heating tank base (11) and the heating tank (2), and be provided with resistant to elevated temperatures sealing ring (10) in its contact position, take said structure, can realize purpose of being convenient to clean and keep in repair heating tank of the present utility model preferably; Last end device at water inlet pipe (5) has the anti-overflow device of being made up of float valve (3) and float valve tube (4), the internal diameter of above-mentioned float valve tube is greater than the internal diameter of water inlet pipe, have the hole that to match with the float valve upper cone at the top of float valve tube, when water in the jar seethes with excitement, float valve is blocked above-mentioned aperture under the promotion of anti-spilling water, reaches the anti-overflow purpose; Also be provided with pressure limiting valve (8) and the pressure-sensitive switch (7) of device in pressure tube (6) at the top of heating tank (2), to prevent that effectively the heating tank internal pressure is excessive and to stop electrothermal tube to continue heating.

Claims
