Description

Direct-type running water purifier suppling cold and warm water}

The present invention relates to a power saving direct type cold and hot water purifier.

For example, water supplies in public places such as schools, hospitals, or large-scale meal facilities are used to purify water from water tank-type water purifiers or tap water (direct water) directly supplied from waterworks. There is a direct water purifier that supplies it. Although the water tank type water purifier or the direct type water purifier has a feature that many people can use it as a large-capacity water supply facility, it has various disadvantages. In particular, the tank type water purifier has a problem that it is very premature to contamination because the tank is not completely sealed.

1 is a view showing for explaining the problem of the conventional water tank cold water purifier.

As shown in the drawing, the conventional water tank type cold / hot water purifier 11 receives the direct water from the outside through the water pipe 13 and passes through the filter unit 15 and the filter unit 15 passing through the inside thereof. Water is received and stored through the main water supply pipe 33, and the water tank 27 having an air hole 27a thereon, and hot water connected to the water tank 27 through the first and second water supply pipes 35 and 37. A tub 39 and a cold water bottle 43 are provided.

The air hole 27a provided in the water tank 27 maintains an atmospheric pressure inside the water tank 27 so that water in the water tank 27 flows smoothly into the hot water tank 39 and the cold water tank 43. will be. For example, as the water in the water tank 27 is supplied to the hot water tank 39 or the cold water tank 43, when the water level in the water tank 27 is lowered, external air is introduced into the air hole 27. Usually, the air hole is fitted with a nonwoven fabric.

The hot water container 39 and the cold water container 43 are supplied with water from the water tank 27 and heated and cooled, respectively, and then supplied to the outside through the hot water discharge pipe 39a and the cold water discharge pipe 43a. In addition, drain pipes 39b and 43b are disposed below the hot water container 39 and the cold water container 43. The drain pipes 39b and 43b are passages for discharging the water stored in the hot water container 39 and the cold water container 43 to the drain pipe 47.

The filter unit 15 is composed of a precipitation filtration filter 17, a precarbon filter 19, a post carbon filter 21, and a membrane filter 23. The precipitation filtration filter 17, the precarbon filter 19, the post carbon filter 21, and the membrane filter 23 are connected in series through a connecting pipe 25 to purify contaminants in direct water.

However, the conventional water tank type cold / hot water purifier 11 configured as described above has a structure in which the air holes 27a are formed in the water tank 27, and thus, the risk of water being exposed to various bacteria is very high. For example, when the outside air is introduced into the water tank 27, various pathogens, fine dust or mold bacteria in the air may enter the water tank 27. This problem is more serious in the case of a hospital that is exposed to various pathogens, or a factory that generates a lot of fine dust.

In addition, an air vent (not shown) is formed inside the hot water tank 39. The air vent is intended to lower the pressure inside the hot water tank 39, but also has a reverse function that prevents water from filling the hot water tank, so that the storage efficiency of the hot water tank 39 is not good. Due to the air vent, only 80% to 90% of the hot water tank cannot fill hot water. Due to this air vent, when hot water is taken out, the hot water is not immediately discharged, but there is an inconvenience that the air comes out first.

The present invention has been made to solve the above problems, and since the direct water supplied from the water supply is heated and cooled in a closed hot water tank and a cold water tank to be supplied to the user, the water does not come into contact with the air, which is caused by bacteria or dust in the air. It is hygienic because there is no pollution problem, and 100% of water can be filled in the hot water tank, so it has high storage efficiency and hot water is discharged immediately when it is taken out. The temperature of the hot water or cold water is always constant because the temperature of the inside of the hot and cold water tank is not drastically changed by the direct water, and in particular, the heating load of the hot water tank is very low since the direct water supplied to the hot water tank is heated first. It is an object of the present invention to provide a power-saving direct type cold and hot water purifier with low power consumption.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Basically, the cold / hot water purifier according to the present invention is a direct water supply method which directly heats or cools tap water (hereinafter, direct water) received from a water supply to a consumer, and has a structure in which water does not come into contact with air, thus providing hygienic and stable water supply. This is possible, and the heating load of the heater is very low since the condensation heat of the refrigerant is used as an auxiliary heat source even when the water is heated.

2 is a view showing the overall configuration of the energy-saving direct type cold and hot water purifier 51 according to the first embodiment of the present invention.

Hereinafter, the same reference numerals as those of the above-mentioned reference numerals denote the same members having the same function.

As shown, the energy-saving direct type cold and hot water purifier 51 according to the first embodiment, the filter unit 15 for filtering and passing the direct water supplied through the direct pipe 13, and the second water supply pipe ( The filter unit 15 is connected to the filter unit 15 through a cold water container 63 for temporarily receiving the filtered water and a first water supply pipe 59 branched from the second water supply pipe 57. ) Is connected to the primary heating unit 53 and receives and receives the filtered direct water, and is connected to the primary heating unit 53 through the connecting pipe 55 and receives the direct water through the connecting pipe 55 And a hot water tank 61 for heating with tea.

In addition, the evaporator 65f surrounds the cold water tank 63 to cool the water in the cold water tank 63, and a condensation coil part 53c is built in the primary heating unit 53.

In addition, the lower portion of the cold water container 63 and the hot water container 61 is provided with drain pipes (43b, 39b). The drain pipes 43b and 39b are passages for discharging the water inside the drain pipe 47 to empty the cold water tank 63 and the hot water tank 61.

First, the cold water container 63 is a sealed case (63a) is completely sealed to the outside and wrapped in the evaporator (65f), and the water pressure reduction unit 54 provided on the inner bottom side of the sealed case (63a) and It consists of a cold water export pipe (43a) for supplying the cold water filled in the sealed case (63a) to the user. A cock (not shown) is provided at the tip of the cold water pipe 43a. Therefore, when the user opens the cock, the cold water in the sealed case 63a is supplied to the outside through the cold water pipe 43a. At this time, the withdrawal pressure of water is a direct water pressure continuously applied to the inside of the sealed case 63a through the second water supply pipe 57.

The water pressure reducing part 54 is installed on the upper part of the ejection part of the second water supply pipe 57, and hits the water flowing through the second water supply pipe 57 into the sealed case 63a to reduce the flow pressure of the direct water. It plays a role. By installing the hydraulic pressure reducing part 54 in this way, the stream line of the direct water discharged into the sealed case 63a does not rise to the upper part but once hits the hydraulic pressure reducing part 54 and stays around the hydraulic pressure reducing part 54 and gradually rises. Done.

 The type of the pressure reduction unit 54 can be changed in various ways, which will be described later.

The evaporator 65f constitutes a heat generating unit together with the compressor 65a, the condenser 65c, and the expansion valve 65e, and the compressor 65a and the expansion valve (through the refrigerant circulation pipe 65b). 65e). The evaporator 65f absorbs heat by evaporating the refrigerant passing therein. That is, the sealed case 63a is cooled. The shape of the evaporator 65f can also be changed according to the shape or size of the sealed case 63a. Reference numeral 65d denotes a cooling fan for cooling the condenser 65c to match the coefficient of performance (COP).

Meanwhile, as shown in FIG. 3, the primary heating unit 53 is sealed to the outside, and an airtight case 53a in which an end portion of the first water supply pipe 59 is fixed to the bottom at the bottom thereof, and the sealing is performed. A pressure reducing part 54 installed at the bottom of the case 53a to attenuate the water pressure of the direct water discharged from the first water supply pipe 59; and a condensing coil part to be built in the sealed case 53a to generate heat; 53c) and a vertical tube 53b fixed vertically to the side of the condensation coil portion 53c.

The condensation coil portion 53c is a portion through which the refrigerant flowing from the compressor 65a to the condensation portion 65c passes. In other words, the water filled in the sealed case 53a is primarily heated. The heating temperature of the condensation coil portion 53c is about 60 ° C. In addition, the shape of the condensation coil portion 53c may be variously changed in order to maximize the contact area with water filled in the sealed case 53a. It may take the form of a coil, for example a spring.

The vertical pipe 53b is a hollow pipe fixed vertically, the upper end of which is open, and the lower end of the vertical pipe 53b communicates with the connecting pipe 55. By placing the vertical pipe 53b in this way, the water remaining in the upper portion of the sealed case 53a can be passed to the hot water tank 61.

The connecting pipe 55 is a pipe connecting the sealed case 53a and the hot water container 61, and the direct water heated by the primary heating part 53 is sheared to the sealed case 61a of the hot water container 61. It is a passage. Since the primary heating unit 53 and the hot water tank 61 are communicated by the connecting pipe 55, the sealed case 53a of the primary heating unit 53 and the sealed case 61a of the hot water tank 61 are connected. The internal pressure is the same. The internal pressure is a direct hydraulic pressure applied from the tap water.

The connecting pipe 55 is opened and closed by an intermediate valve 55a. The intermediate valve 55a is a normally closed valve and is opened when water inside the hot water tank 61 is supplied to the outside.

In particular, a pressure reducing capillary tube 55b is provided between the upstream connecting pipe 55 of the intermediate valve 55a and the drain tube 47 as a pressure reducing unit. When the pressure inside the sealed case 53a rises above the set value with the intermediate valve 55a being closed, the decompression capillary 55b draws the water inside the sealed case 53a to the drain pipe 47 to close the sealed case. Prevent excessive pressure rise of (53a).

The hot water tank 61 is a sealed case 61a for receiving and receiving the primary heated water transferred through the connecting pipe 55 therein, and is installed at the bottom of the sealed case 61a and connected to the connecting pipe 55. And a hydraulic pressure reduction part 54 for reducing the jet pressure of the direct water discharged into the sealed case 61a, and a heater 61b installed on the side of the hydraulic pressure reduction part 54 and heating water in a secondary manner. It is composed of a porous separator 61k fixed to the upper portion of the heater 61b. In addition, the upper portion of the sealed case (61a) is provided with a hot water outlet pipe (39a) for supplying the secondary heated water to the consumer.

The heating temperature of the heater 61b is about 90 ° C.

As shown in Fig. 7, the porous separation plate 61k is a disk-shaped member having a predetermined thickness in which a plurality of through holes 61m are formed, and is fixed to the inner circumferential surface of the sealing case 61a, so The inner space of 61a) is divided up and down. By providing the porous separator 61k in this way, even if the direct water is ejected through the connecting pipe 55, the water on the upper portion of the porous separator 61k hardly fluctuates, so that pulsation does not occur in the hot water output water.

In addition, the hot water tank 61 is provided with a steam condensation unit. The steam condensing unit extracts the steam generated inside the sealed case 61a to the outside of the sealed case 61a and condenses it to return to the sealed case 61a, and both ends thereof are fixed to the sealed case 61a. It consists of a circulation pipe 61d and the condensation capillary tube 61c located in the middle part of the said circulation pipe 61d. The condensation capillary tube 61c serves to condense through the steam.

In addition, a discharge pipe 61e is branched and installed between the circulation pipe 61d and the drain pipe 47. The discharge pipe 61e has a valve 61g as a passage through which the condensed water that has passed through the condensation capillary tube 61c is discharged to the drain pipe 47. The discharge pipe 61e is opened when it is not necessary to return the condensed water to the sealed case 61a. When the valve 61g is shut off and the valve 61f provided in the circulation pipe 61d is opened, condensed water is recovered.

As a result, the direct type cold / hot water purifier of the first embodiment configured as described above heats the direct water first by using the condensation heat of the refrigerant constituting the cooling system and secondly heats it by using the heater, thereby greatly increasing the heating load of the heater. I can alleviate it.

4 to 6 are diagrams illustrating various examples of the hydraulic pressure reducing unit shown in FIG. 2.

Referring to Figure 4, it can be seen that the hydraulic pressure reducing portion 54 is installed at the bottom of the sealed case (53a, 61a, 63a). 4 is a screen net 54b disposed above the connecting pipe 55, the second water feed pipe 57, and the first water feed pipe 59, and the screen net 54b horizontally. It is composed of a plurality of legs (54c) fixed by the.

The screen net 54b sharply lowers the flow pressure by passing the direct water discharged upwardly from the bottom to separate the flow of the direct water into several strands. Accordingly, the fresh water supplied is mixed with the existing water without any fluctuations.

The hydraulic damping unit 54 of the type shown in FIG. 5 is composed of a frame 54d having a rotary shaft 54e at its upper end and a plurality of vanes 54f fixed to the rotary shaft 54e. . The blade 54f rotates against the direct water ejected upward from the lower portion and attenuates the upward flow pressure of the direct water. The blade 54f rotates in the clockwise direction in the drawing and drives the flow of the direct water jetted upward to the wall surface so that the direct water also hits the wall surface.

The hydraulic pressure reduction part 54 of FIG. 6 is a frame which fixes the inclination plate 54g and the plurality of inclination plates 54g which are located in the upper part of the said connection pipe 55 or the 1st and 2nd water supply pipes 59 and 57. (54k). The inclined plate 54g collides with the direct water ejected upward to absorb the warm energy of the direct water.

8 is a block diagram showing the overall configuration of the energy-saving direct type cold and hot water purifier according to the second embodiment of the present invention, Figure 9 is a view showing the internal structure of the cold water container shown in FIG.

Description of the same reference numerals as those shown in FIG. 2 will be omitted.

As shown, the energy-saving direct type cold and hot water purifier 51 according to the second embodiment includes a compressor 65a, a condenser 65c, connected through a refrigerant circulation pipe 65b through which refrigerant passes, And a heat generating section including an expansion valve 65e, an evaporation section 65f, a primary heating section 53, and a hot water tank 61. The heat generating portion generates heat through the condensation coil portion 53c as a general cooling system, and cools the surrounding temperature through the evaporation portion 65f.

In addition, the primary heating unit 53 and the hot water container 61 heats the direct water received through the filter unit 15 and supplies it to the outside through the hot water outlet pipe 39a.

On the other hand, in the direct type cold / hot water purifier 51 according to the second embodiment, the cold water container 67 for supplying cold water to the consumer is provided in the box-shaped case 67a and the case 67a, A cooling chamber 67b for accommodating the cooling water 67c provided from the outside and having the evaporation unit 65f embedded therein to allow the evaporation unit to cool the cooling water 67c, and accommodated in the cooling chamber 67b. A coil type cooling coil part 67d cooled by the cooling water 67c is provided. The case 67a accommodates the cooling chamber 67b therein so as not to be seen from the outside.

In particular, one end of the cooling coil portion 67d is connected to the second water supply pipe 67, and the other end thereof is connected to the cold water export pipe 43a. Therefore, the direct water supplied through the filter part 15 to the second water supply pipe 57 passes directly through the cooling coil part 67d and exits directly to the cold water export pipe 43a in a cooled state. This is a typical direct-type water supply system where water comes out of a faucet.

Water filled in the cooling chamber 67b serves as a cooling water for cooling the cooling coil portion 67d in a state of being first cooled by the evaporator 65f. The cooling water 67c is filled in the cooling chamber 67b through the supplemental water pipe 67n branched from the second water supply pipe 57. Therefore, when the water inside the cooling chamber 67b is insufficient for evaporation or various reasons, it can be replenished at any time through the replenishment water pipe 67n. Normally, the valve 67p of the supplemental water pipe 67n is blocked so that all of the water supplied through the second water feed pipe 57 is directed to the cooling coil part 67d.

The evaporator 65f may take the form of a coil as shown in FIG. 9. In other words, the pipe through which the refrigerant passes is bent in a coil shape and embedded in the cooling chamber 67b.

In addition, the cooling coil portion 67d also takes the form of a coil and is disposed inside the evaporation portion 65f. The cooling coil portion 67d is cooled by the cooling water 67c to cool the direct water passing through the cooling coil portion 67d.

Reference numeral 67m in Fig. 9 is a heat insulating material.

In addition, the upper end portion of the overflow tube 67f is located above the cooling chamber 67b. The overflow pipe 67f serves to receive the overflowed coolant from the cooling chamber 67b and to send it to the drain pipe 47. It goes without saying that the water surface of the cooling water 67c is located at the upper end of the overflow pipe 67f.

A circulation motor 67e is provided below the cooling chamber 67b. The circulation motor 67e is for circulating water in the cooling chamber 67b, and sucks the cooling water 67c through the cooling water circulation pipe 67k, and then ejects it back into the cooling chamber 67b. Do it. In some cases, the circulation motor 67e may be installed inside the cooling chamber 67b.
