Abstract

The utility model relates to a heating device of cold and hot type drinking-water appliances which use turnaround bottles (1) of drinking water with large-scale packings. The utility model is characterized in that water which is positioned inside a water receiving tank (2) or on the upper level of a cold water tank (3) firstly flows into an urn with device for keeping beverage hot or cool and then flows into a hot tank, hot water is effectively prevented from flowing backwards into the water receiving tank or the cold water tank, the cold and hot water can not be confused, and the utilization ratio of electrical energy of a complete machine is improved.

Description

Urn with device for keeping beverage hot or cool

The utility model belongs to solar heat protection aqueous reflux device in a kind of cold and hot water drinking machine heating process of using big packing drinkable water week rolling bottle.

At present, the heating tank of commercial cold and hot water drinking machine is by turnover bottle graft water pot or the direct moisturizing of cold water tank epimere water layer, owing in airtight heating tank, heat, the hot water that expands flows backwards along its moisturizing road inevitably, can make wherein temperature of cold water rises in flowing back to cold water tank, but flow back in the water receiving jar (the water receiving jar is cold and hot water pot moisturizing simultaneously), the water that temperature is high adds in cold jar also can make temperature of cold water rises, cause waste of energy, overall efficiency reduces.

The purpose of this utility model is to improve above-mentioned deficiency, introduces the anti-heat-flow device that returns, and improves utilization rate of electrical.

The utility model feature is that a Urn with device for keeping beverage hot or cool is arranged in the middle of the hot-water cylinder water replanishing device, water receiving jar water interior or the cold water tank upper strata is introduced into the anti-heat jar that returns by back-shaped pipe, enter in the heat jar by filling pipe by Urn with device for keeping beverage hot or cool then, there is the gland steam exhauster that is higher than the water surface to link to each other in the Urn with device for keeping beverage hot or cool with the logical steam pipe of hot-water cylinder upper end, be used for exhaust moisturizing and discharging steam, there is the water proof circle at Urn with device for keeping beverage hot or cool filling pipe place and is lower than the water surface, the condensing cover that Urn with device for keeping beverage hot or cool has a good conductor to make, condensed water is collected back in the Urn with device for keeping beverage hot or cool, free vent is arranged on the condensing cover.

Fig. 1 be the utility model from the water receiving jar through Urn with device for keeping beverage hot or cool moisturizing schematic diagram.

Fig. 2 is the utility model from cold jar through Urn with device for keeping beverage hot or cool moisturizing schematic diagram.

Now specify in conjunction with the accompanying drawings

As Fig. 1,2, the water of big packing drinkable water week rolling bottle (1) enters in the water receiving jar (2), the water on water receiving jar or its upper strata passes through back-shaped pipe (4) at first from Urn with device for keeping beverage hot or cool (5), and then enter in the heat jar (7) by filling pipe (6) by Urn with device for keeping beverage hot or cool, there is a gland steam exhauster (8) to be connected in the Urn with device for keeping beverage hot or cool with a heat jar breather pipe (9), during initial moisturizing, be used for heat jar exhaust moisturizing, when expiring and heat, heat jar water can discharge steam, gland steam exhauster is higher than the Urn with device for keeping beverage hot or cool water surface, there is water proof circle (10) at the filling pipe place in the Urn with device for keeping beverage hot or cool, is lower than the Urn with device for keeping beverage hot or cool water surface, the condensing cover (11) that Urn with device for keeping beverage hot or cool top has a good conductor to make, one aperture is arranged, for communicating on the condensing cover with atmosphere.

During heating, overwhelming majority steam in-line arrangement steam pipe enters the Urn with device for keeping beverage hot or cool upper space, meet condensing cover and condense into water, drip back in the Urn with device for keeping beverage hot or cool, few part steam is disposed to the air pressure that makes in the atmosphere in the Urn with device for keeping beverage hot or cool by aperture on the condensing cover identical with atmospheric pressure, the water of thermal expansion returns Urn with device for keeping beverage hot or cool along filling pipe, along the upwards diffusion of water proof circle, in cause Urn with device for keeping beverage hot or cool a little rising of the water surface in it, a little normal-temperature water that can only allow this moment to be lower than the water proof circle is returned in water receiving jar or the cold jar by back-shaped pipe, prevents that effectively hot water from returning in water receiving jar or the cold jar, do not obscure hot and cold water, avoid waste of energy, improved overall efficiency.

Claims

1, a kind of Urn with device for keeping beverage hot or cool that uses in the cold and hot water drinking machine heating process of packing drinkable water week rolling bottle (1) greatly, it is characterized in that a Urn with device for keeping beverage hot or cool (5) is arranged in the middle of the hot-water cylinder moisturizing, water receiving jar (2) water interior or its upper strata is introduced into Urn with device for keeping beverage hot or cool by back-shaped pipe (4), being entered by filling pipe (6) by Urn with device for keeping beverage hot or cool then has the gland steam exhauster (8) that is higher than the water surface to link to each other the condensing cover (11) that has a good conductor to make on the Urn with device for keeping beverage hot or cool with the logical steam pipe (9) of hot-water cylinder upper end in heat jar interior (7), the Urn with device for keeping beverage hot or cool.Free vent is stamped in condensation.

2, Urn with device for keeping beverage hot or cool according to claim 1 is characterized in that there is water proof circle (10) at the filling pipe place and is lower than the water surface.
