Description

Keep warm device for a water purifier

The present invention relates to a cold and warm water purifier, and more specifically, to open and close the flow path by a pressure difference so as not to lose the heat of the cold and hot water, as well as the space for cold water and hot water in the reservoir to collect the filtered purified water. It relates to a heat shield of cold and warm water purifier for maintaining the temperature.

In general, the water purification process and the internal structure of the water purifier is a pre-filter (110) for removing foreign particles of relatively large particles, such as dust sand rust contained in raw water, that is, tap water, and also by adsorbing chlorine and organic substances Free carbon filter 120 to remove, membrane 130, and residual chlorine and odor to remove more than 99% of heavy metals THM, phosphate phenol, such as small particles of more than 1 million microns, such as bacteria and viruses, carcinogens, environmental hormones It is made of an activated carbon filter 140, etc. to remove the purified water is collected and collected in the storage tank 200. The reason for the existence of the purified water tank 200 is that the capacity of the membrane 130 is limited so that the drinking water is stored in advance so that the purified water can be always used. In more detail, the water storage tank 200 has a main compartment 210 for collecting the whole purified water, and a cold water collector 220 for making cold water at a lower portion thereof, the space being partitioned by a cover 230, In addition, the cold water collection unit 220 side is provided with an evaporator 320 of the cooling system that absorbs the heat of the refrigerant through the compressor 310, the absorbed heat is to be discharged through the condenser 330, the water The lower portion of the tank 200 is provided with a boiler 350 to warm to any temperature when discharged through the faucet 360, 360 '.

That is, in the conventional water storage tank, the cover is provided between the main water collecting portion for collecting purified water and the cold water collecting portion for making cold water to freely flow, thereby forming a layer naturally due to temperature difference, thereby blocking the clean water and cold water at room temperature. In this case, the cover is not formed any device and structure for selectively introducing the purified water at room temperature by the difference in water pressure when the cold water in the cold water collecting section is not filled, but only the inlet 230a is formed. Therefore, there is a problem that the thermal efficiency is extremely reduced due to the phenomenon that it is not kept warm and is easily diluted with room temperature purified water through the hole.

If the water tank at room temperature is placed at room temperature and the hot water tank is located at the bottom, the hot water warmed above the water temperature at room temperature is higher because of convection, so the storage of hot water is blocked when there is no separate flow path blocking device. Is impossible.

Therefore, the present invention was created to solve the above problems, and its purpose is to establish a space for cold water and hot water in the reservoir where the purified purified water is collected, and to prevent the heat of the cold and hot water from being lost. It is to provide a heat shield of the cold, warm water purifier for maintaining the temperature to open and close the.

The present invention for achieving the above object, by using the main catchment of the water collecting tank and the evaporator and condenser of the cooling system partitions the cold water and hot water collecting unit for generating cold water and hot water heat shielding to protect heat from the clean water at room temperature In configuring the device,

A blocking plate installed between the main water collecting portion collecting water at room temperature and the cold water and hot water collecting portion formed integrally therewith, and having a plurality of inflow holes communicating therewith;

It is installed to enable the flow in the vertical direction on the blocking plate and has a feature configured to include a float mechanism to protect the heat of cold and hot water in a full state by selectively opening and closing by buoyancy.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic configuration diagram showing a thermal cutoff device of the cold, warm water purifier for maintaining the temperature according to the present invention, and thus the cold, warm system.

Before describing the core configuration of the present invention, the cold and on-system applied in the present invention will be described.

Although it is mentioned through FIG. 1, the boiler 350 is generally employed to generate hot water, but the boiler is always turned on to supply an appropriate temperature even when hot water is not taken out. High heat transfer costs are a major disadvantage because they must be kept in place, or the heaters must be turned on regularly (eg: 15 minutes on an hour, 45 minutes off).

In order to overcome this problem, the present invention is a primary heating means for generating hot water waste heat in the process of condensing the refrigerant through the condenser 33 as shown in Figure 2 (the heating temperature at this time is 40 to 50 ℃) and by using the direct heating type heater 40, which is a secondary heating means to increase the temperature to 70 ~ 95 ℃ instantaneously, the heat transfer cost is reduced by more than 30% and does not need to configure a separate heat radiation fin The size of the water purifier according to the effect can be reduced.

The core of the present invention is to solve the problem that occurs when the purified water collected in the storage tank 20 in the cold, warm water purifier of this configuration is generated by cold water and hot water.

That is, in the water storage tank 20, the main water collecting portion 21 for collecting the purified water at room temperature, the cold water collecting portion 22 provided with the evaporator 32, and the hot water collecting portion 22 'including the condenser 33 are separate. Forming a jaw (23, 23 ') between the main water collecting portion 21 and the cold water collecting portion 22, the main water collecting portion 21 and the hot water collecting portion 22' to be partitioned into spaces,

Block plates 24 and 24 ', which are fitted to the fitting jaws 23 and 23', respectively, and are provided with a plurality of inlets 24a and 24a 'for introducing the purified water from the main catcher 21 onto the surface. ),

The inlet hole 24a (24a) is installed by the buoyancy when the water in the cold and hot water collecting parts 22 and 22 'is fully filled in the center of the blocking plate 24 and 24' so as to be able to flow upward and downward. It is comprised by the float mechanism 25 (25 ') etc. which block "' and block the inflow of purified water.

Of course, the float mechanism 25 and 25 'should be made of a material having a specific gravity smaller than that of water, that is, a material capable of generating buoyancy.

It describes the operation of the present invention configured as described above.

First, the purified water of the condition that the raw water can be drinking while passing through the pre-filter 11, the pre-carbon filter 12, the membrane 13, and the activated carbon filter 14 is made, the main water collecting portion 21 of the water storage tank 20 Collected in the cold water collecting portion 22 and the hot water collecting portion 22 ', so that each water collecting portion 21, 22 or 22 is not overflowed. The cooling system is operated in a full state at ') as in the prior art.

Meanwhile, in the evaporator 32 located at the cold water collecting unit 22 side of the water storage tank 20 by the operation of the cooling system, the constant temperature of the room temperature is changed to cool water of 5 to 10 ° C. in the process of absorbing the heat of the refrigerant. In the hot water collection tank 22 ′ of the water storage tank 20 in which the condenser 33 dissipates heat generated while the refrigerant is condensed, the purified water is lukewarm to 40 to 50 ° C. due to the waste heat.

At this time, when the user operates the faucet (36) (36 ') to drink cold water or hot water, the cold water can be immediately discharged to drink the cold water through the discharge passage 37, and in the case of hot water discharge passage (37) The direct heating heater 40, which is the secondary heating means located on the '), is operated to instantly warm up the preheated hot water to 75 to 95 ° C to enjoy hot hot water.

At this time, if a certain amount of cold water or hot water is discharged through the faucets 36 and 36 ', a space corresponding to the amount of water is formed in each of the collecting portions 22 and 22', and the float mechanisms 25 and 25 ' As buoyancy is lost, a certain amount of purified water is introduced through the inlet holes 24a and 24a 'of the blocking plates 24 and 24'.

When the sump tanks 22 and 22 'are in a full state again, the inlet holes 24a and 24a' are blocked by the restored buoyancy to prevent the inflow of purified water and block further temperature discharge.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

According to the configuration and operation of the present invention as described above, by including the waste heat generated in the condenser in one process for making hot water without radiating heat to the outside, it is possible to reduce the heat transfer cost as well as the conventional boiler for making hot water And since it does not need a fin fin, there is an advantage that can be configured in a compact volume of the water purifier,

In addition, in view of the above configuration and operation there is an advantage that the thermal efficiency is greatly increased because the purified water at room temperature can be selectively isolated or selectively introduced by buoyancy to warm the hot water and cold water generated in each collection tank.
