Abstract

The utility model relates to a drinking machine which can simultaneously flow out boiled water and warm boiled water, in particular to a heat exchanger of water drinking machine. The utility model comprises a hollow plate pipe and tee joint connectors which are arranged on the two ends of the hollow pipe coil; the inside of the hollow pipe coil is at least provided with two inner pipes, and the two ends of the two inner pipes respectively extend out from one connector of the tee joints, the clearance between the inner walls of the tee joint connectors on the outer end of the connector and the outer wall of the inner pipe is airproofed by liquid, while the other two connectors of the tee joint connectors form a channel together with the clearance between the inner wall of the hollow pipe coil and the outer wall of the inner pipe. The utility model has reasonable design and notable energy saving effect, and lightens the weight of the drinking machine and reduces the cost.

Description

The heat exchanger of water dispenser

(1) technical field

The utility model relates to a kind of water dispenser that can go out boiling water and warm boiling water simultaneously, specifically relates to the heat exchanger of this kind water dispenser.

(2) background technology

Existing water dispenser major part is to have only directly to go out hot water, this thinks directly to drink to some public arenas and brings difficulty, the applicant has applied for energy-saving drinking machine on January 26th, 1999, the patent No. 99235282.7, publication number 2366021Y, heat converter structure wherein is that boiling water tube is enclosed within the cold water pipe, cold water has absorbed the heat of a part of hot water before heating like this, it is capable of direct drinking that temperature is reduced to the people after the boiling water heat release, but it is only to overlap a boiling water tube in the cold water pipe that this structure has a drawback, and the length of whole like this coil pipe is very long, has increased water dispenser weight, large-scale relatively water dispenser, this cooling are not clearly.

(3) summary of the invention

Therefore, the purpose of this utility model be to provide a kind of applicable various types, cooling-down effect obviously, the heat exchanger of more energy-conservation water dispenser.

The purpose of this utility model is to realize like this.

A kind of heat exchanger of water dispenser, comprise a hollow coil pipe and the three-way connection that is located at hollow coil pipe two ends, at least be provided with pipe in two in the hollow coil pipe, an interface of three-way connection is extended at interior pipe two ends respectively, in the three-way connection inwall of this interface outer end and the sealing of the interstitial fluid between the outer wall of inner tube, two interfaces in addition of three-way connection and the gap between hollow disc inside pipe wall and the outer wall of inner tube form a passage.

Technique scheme also can be done further perfect by following technical proposals.

Described liquid sealing is a sealing, is that sealing is simple and reliable with the effect of welded seal, and also can fixes interior pipe.

Described in each the caliber of pipe can be identical also can be inequality, this can go out the warm boiling water of all temps as required.

The utility model reasonable in design, energy-saving effect is remarkable, has alleviated water dispenser weight, has reduced cost.

Fig. 2 is the utility model theory structure schematic diagram;

Fig. 3 is Fig. 2 side schematic view;

Fig. 4 is the A-A sectional drawing.

(5) specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment, in conjunction with the accompanying drawings, a kind of heat exchanger of water dispenser, comprise a hollow coil pipe 1 and the three-way connection 2 that is located at hollow coil pipe 1 two ends, be provided with pipe 3 in five hot water in the hollow coil pipe 1, an interface 4 of three-way connection 2 is extended at the two ends of five interior pipes 3 of hot water respectively, gap in three-way connection 2 inwalls of these interface 4 outer ends and five hot water between pipe 3 outer walls is with weldering 5 sealings, and the gaps of managing between 3 outer walls in two interfaces 6 in addition of three-way connection 2 and hollow coil pipe 1 inwall and five hot water form a cold water channel 7.

Pipe 3 flowed out from the other end in boiling water entered from an end of interior pipe 3, cold water enters hollow coil pipe 1 from another interface 6 outflows from an interface 6 of three-way connection 2, heat exchange takes place in boiling water and cold water in hollow coil pipe 1, make cold water preheating before heating, and boiling water becomes warm water and directly drinks.

Claims

1, a kind of heat exchanger of water dispenser, comprise a hollow coil pipe and the three-way connection that is located at hollow coil pipe two ends, it is characterized in that: be provided with pipe in two in the hollow coil pipe at least, an interface of three-way connection is extended at interior pipe two ends respectively, in the three-way connection inwall of this interface outer end and the sealing of the interstitial fluid between the outer wall of inner tube, two interfaces in addition of three-way connection and the gap between hollow disc inside pipe wall and the outer wall of inner tube form a passage.

2, the heat exchanger of water dispenser according to claim 1 is characterized in that: described liquid sealing is a sealing.

3, the heat exchanger of water dispenser according to claim 1 is characterized in that: described in each the caliber of pipe can be identical also can be inequality.
