Background

With the increasing demand of people for water quality, water purifiers have become essential living goods basically. Various manufacturers have proposed various water purifiers to suit different application places. Under-kitchen water purifiers are becoming more popular as a common water purifier.

Under-kitchen water purifiers are typically mounted inside the cabinet of a kitchen. The under-kitchen water purifier not only can bring purified water for each family, but also has the advantages of simple, convenient and reasonable installation, no occupied space and the like. When the water purifier is used, the water can be purified by opening the water outlet end of the under-kitchen water purifier, and the operation is very convenient.

However, in practical application, the under-kitchen water purifier has a single function and cannot meet the requirements of users.

SUMMERY OF THE UTILITY MODEL

To at least partially solve the problems in the prior art, according to one aspect of the present invention, a water purifier is provided. Under the kitchen purifier has into water end and goes out water end, and under the kitchen purifier includes: the water purification component comprises a raw water inlet and a purified water outlet, and the raw water inlet is communicated to the water inlet end; the cold water assembly comprises a purified water storage device and a refrigerating device, the purified water storage device comprises a purified water inlet and a cold purified water outlet, the purified water inlet is communicated with the purified water outlet, and the cold purified water outlet is communicated with the water outlet end; the refrigerating device is connected to the water purifying and storing device and is used for refrigerating the purified water in the water purifying and storing device.

The under-kitchen water purifier provided by the embodiment in the field can realize the function of preparing cold and purified water, so that the use requirement of a user can be met. In addition, the water purifying and storing device can be used as a container for storing purified water and can also be used as a container for reducing water temperature, so that the structure of the under-kitchen water purifier can be simpler, and the miniaturization can be realized. Because the space inside the cabinet of the kitchen is very limited, the miniaturized under-kitchen water purifier is particularly suitable for use.

For the water purifier with the refrigerating device positioned on the water outlet pipeline, the refrigerating power of the refrigerating device is limited, so the flow rate of cold purified water is related to the water temperature required by a user. Specifically, when the water temperature required by a user is high, the water purifier needs to pump cold purified water in the purified water storage device to a water outlet end at a high flow rate by arranging a flow control device such as a water suction pump or a flow valve; however, when the water temperature required by the user is low, the flow control device can only pump the cold purified water in the purified water storage device to the water outlet end at a small flow rate. In addition, the ambient temperature also affects the flow rate of cold purified water, for example, compared with winter, the temperature of water in the water purifying and storing device is higher in summer, and it is more difficult to cool the water to the required temperature. Therefore, even if a large-flux water purification assembly is adopted, the flow of the cold and purified water accessed by a user is still greatly limited. Therefore, the water purifier cannot meet the requirement of a user on large-flow cold purified water. Moreover, the arrangement of the flow control device also leads to complex control logic, requires a large amount of experiments to verify the relationship between the flow and the water temperature, and is difficult to achieve accurate control of the water temperature due to the influence of environmental factors.

The under-kitchen water purifier provided by the embodiment of the utility model can refrigerate the static water in the water purifying and storing device through the refrigerating device, so that the temperature of the purified water in the water purifying and storing device can be accurately controlled. Therefore, the under-kitchen water purifier does not need to be provided with a flow control device to control the flow of the cold purified water, and the outlet flow of the cold purified water is large. That is, the water production capacity of the under-kitchen water purifier may not be limited by the cooling power of the cooling device and the ambient temperature, and is mainly determined by the water production capacity of the water purification assembly. Thus, the water purification assembly may employ a large flux cartridge assembly.

In addition, if need can also set up the heat preservation function on water purification water storage device, like this when the user needs the water intaking, need not to wait for refrigerated time, the efficiency of water intaking is higher.

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.

In order to realize more functions, the embodiment of the utility model provides a water purifier under a kitchen.

Fig. 1 shows the water circuit principle of a under-kitchen water purifier, wherein arrows schematically show the flow direction of water. Fig. 2 to 8 show the structure of the under-kitchen water purifier.

As shown in fig. 1-8, the under-kitchen purifier may have an inlet end 110 and an outlet end 120. Water may enter the under-kitchen purifier through the water inlet 110. Illustratively, the water inlet end 110 may be connected to a raw water tank, a municipal waterway, or the like. Preferably, the water inlet solenoid valve 620 may be disposed on the pipeline of the water inlet end 110. The water inlet solenoid valve 620 is opened and closed to control the connection and disconnection of the water inlet end 110, so as to achieve the purpose of controlling water inlet. The water filtered by the under-kitchen water purifier can flow out of the under-kitchen water purifier through the water outlet end 120. Illustratively, the water outlet end 120 may be connected to a user's water intake, including but not limited to a faucet above a cabinet. The on-off of the water outlet end 120 is controlled by opening and closing the faucet, so as to achieve the purpose of controlling the water outlet.

The under-kitchen water purifier may include a water purification assembly 200 and a cold water assembly 300. The cold water unit 300 may include a clean water storage device 310 and a refrigeration device 320.

The water purification assembly 200 may include a raw water inlet and a purified water outlet. The raw water inlet of the water purification assembly 200 may be communicated to the water inlet port 110. The clean water storage device 310 may include a clean water inlet and a cold clean water outlet. The purified water outlet of the water purifying assembly 200 may be communicated to the purified water inlet of the purified water storage device 310. The cold purified water outlet of the purified water storage device 310 may be connected to the water outlet end 120.

When the under-kitchen water purifier works, water can enter the water purification assembly 200 through the water inlet end 110 and the raw water inlet in sequence. The water purification assembly 200 may be used to filter water to produce purified water. The water purification unit 200 may employ various types of water purification units known in the art or may come out in the future as long as water can be filtered. The purified water filtered by the water purifying assembly 200 may sequentially pass through the purified water outlet and the purified water inlet and enter the purified water storage device 310. The purified water storage device 310 may be used to store filtered purified water. Illustratively, the clean water storage device 310 includes, but is not limited to, a water tank or sink, etc. The refrigeration device 320 may be connected to the purified water storage device 310 by any suitable means such as welding, connection, or abutment. The refrigerating device 320 may refrigerate the purified water in the purified water storage device 310. Refrigeration device 320 may take the form of various types of refrigeration devices known in the art or that may occur in the future, including but not limited to refrigerators. Thus, the temperature of the purified water in the purified water storage device 310 can be reduced, and the cold purified water is obtained. The cold purified water can flow out of the under-kitchen water purifier sequentially through the cold purified water outlet and the water outlet end 120, so that the water can be used by a user.

It is understood that the refrigeration capacity of the clean water storage unit 310 can be controlled. That is, the user can control the refrigerating capacity of the purified water storage device 310 according to the actual use requirement of the purified water temperature. Thus, the user experience is better.

Therefore, the under-kitchen water purifier provided by the embodiment in the field can realize the function of preparing cold purified water, so that the use requirement of a user can be met. In addition, since the purified water storage device 310 can be used as a container for storing purified water and a container for reducing water temperature, the structure of the under-kitchen water purifier can be more concise, and miniaturization can be realized. Because the space inside the cabinet of the kitchen is very limited, the miniaturized under-kitchen water purifier is particularly suitable for use.

The under-kitchen water purifier of the embodiment of the utility model can refrigerate the static water in the water purifying and storing device 310 through the refrigerating device 320, so that the temperature of the purified water in the water purifying and storing device 310 can be accurately controlled. Therefore, the under-kitchen water purifier does not need to be provided with a flow control device to control the flow of the cold purified water, and the outlet flow of the cold purified water is large. That is, the water production capacity of the under-kitchen water purifier may not be limited by the cooling power of the cooling device 320 and the ambient temperature, which is mainly determined by the water production capacity of the water purification assembly 200. Thus, the water purification assembly 200 may employ a large-flux cartridge assembly.

In addition, if need also can set up the heat preservation function on water purification water storage device 310, like this when the user needs the water intaking, need not to wait for refrigerated time, the efficiency of water intaking is higher. Meanwhile, a flow control device is not required, so that secondary pollution of an intermediate link to cold purified water is reduced, noise and power consumption are reduced, and cost is saved. In addition, the volume of the under-kitchen water purifier is reduced.

It should be noted that, although the refrigeration device 320 can refrigerate the purified water in the purified water storage device 310, in practical applications, the refrigeration device 320 can be turned off if the user does not need cold water. Thus, the temperature of the purified water in the purified water storage device 310 does not decrease. That is, the user can select to turn on or turn off the water purifying and storing device 310 according to the actual use requirement of the purified water temperature. Alternatively, the number of the water outlet ends 120 may be plural, for example, two. The clean water outlet of the water purifying assembly 200 may also be directly connected to the water outlet 120. Thus, when the user needs cold purified water, the tap of the water outlet end 120 communicated with the cold purified water outlet of the refrigeration device 320 can be opened, and when the user needs normal temperature water, the tap of the water outlet end 120 communicated with the purified water outlet of the water purification assembly 200 can be opened.

As an exemplary embodiment, as shown in fig. 1-8, the cold water assembly 300 may further include a water temperature detector 330 and a controller (not shown).

The water temperature detector 330 may be disposed on the purified water storage device 310. The water temperature detector 330 may be used to detect the temperature of water in the purified water storage device 310. The water temperature detector 330 may employ various types of water temperature detectors known in the art or that may occur in the future, including but not limited to thermistors. Preferably, the water temperature detector 330 may be disposed outside the water purifying and storing device 310, and may be directly connected to the outer side of the water purifying and storing device 310 by welding or the like. Thus, the water temperature detector 330 does not cause secondary pollution to the purified water in the purified water storage device 310, thereby ensuring the health of the user.

The controller can be built by adopting electronic elements such as a timer, a comparator, a register, a digital logic circuit and the like, or can be realized by adopting processor chips such as a singlechip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC) and the like and peripheral circuits thereof. The controller may be electrically connected to the water temperature detector 330. The controller may be configured to control the operation of the cooling device 320 according to the temperature of the water detected by the water temperature detector 330. Specifically, the controller may be configured to control operation of the refrigeration device 320 when the water temperature is greater than a temperature threshold. Of course, the controller may be used to control the chiller 320 to stop operating when the water temperature is less than another temperature threshold. Wherein, the user can set the temperature threshold according to the actual use requirement. Through the arrangement, the cold water assembly 300 can be automatically controlled, so that the under-kitchen water purifier is more intelligent.

As an exemplary embodiment, the under-kitchen water purifier may be further provided with a display panel (not shown). The under-kitchen water purifier may include a housing 410, and the housing 410 may be used to protect an internal structure and beautify appearance. The display panel may be disposed on a housing 410 of the under-kitchen water purifier. The display panel may be electrically connected to the controller, and is used for displaying information such as a current water temperature in the water purifying and storing device 310 and a temperature threshold set by a user. In this way, the water temperature in the water purification and storage device 310 detected by the water temperature detector 330 can be displayed by the display panel, and the user can intuitively know the current water temperature in the water purification and storage device 310.

As an exemplary embodiment, the clean water storage device 310 may include a thermal insulation water tank, i.e., a cold tank. The shape of the heat preservation water container can be any, including but not limited to a cylinder or a sphere, etc. The heat preservation water storage container can delay the heat dissipation of the purified water in the heat preservation water storage container so as to achieve the purpose of heat preservation. Thus, the refrigeration device 320 has lower energy consumption, and the under-kitchen water purifier is more environment-friendly. The heat-preservation water storage container is particularly suitable for use in hot environments.

The structure of the refrigerating apparatus 320 will be exemplarily described below.

As shown in fig. 1-8, the refrigeration unit 320 may include a compressor 321, a condenser 322, and an evaporator 323. The outlet end of the compressor 321 may communicate with the inlet end of the condenser 322. The outlet end of the condenser 322 may communicate with the inlet end of the evaporator 323. The outlet end of the evaporator 323 may communicate with the inlet end of the compressor 321. The evaporator 323 may be connected to the purified water storage unit 310. The evaporator 323 is a heat exchange member that can transfer cold energy to the purified water in the purified water storage unit 310 by being attached to the outside of the purified water storage unit 310.

A compressor is a driven fluid machine that raises a low-pressure refrigerant (for example, freon or ammonia) gas into a high-pressure refrigerant gas, and is a heart of a refrigeration apparatus. The compressor may generally consist of a housing, a motor, a cylinder, a piston, control equipment (e.g., a starter and a thermal protector), and a cooling system. The starter can be basically of two types, i.e., a weight type and a PTC (positive temperature coefficient) type. PTC starters are more advanced. The cooling mode of the cooling system can comprise oil cooling or natural cooling and the like. The condenser is mainly used to discharge heat of high-temperature and high-pressure refrigerant gas discharged from the compressor to the external environment in a rapid manner, thereby converting the refrigerant gas into refrigerant liquid. Evaporators are used primarily for converting refrigerant liquid to refrigerant gas. The working principles of compressors, condensers and evaporators are known to those skilled in the art and will not be described in detail for the sake of brevity.

In use, the compressor 321 can suck low-temperature and low-pressure refrigerant gas from its inlet end, and then, after the compressor is operated by the motor to drive the piston to compress the refrigerant gas, discharge the high-temperature and high-pressure refrigerant gas to its outlet end. Refrigerant gas at high temperature and pressure may enter the condenser 322 through the inlet end of the condenser 322, thereby converting the refrigerant gas into a refrigerant liquid. Refrigerant liquid may pass sequentially through the outlet end of condenser 322 and the inlet end of evaporator 323 into evaporator 323. The evaporator 323 may expand and evaporate the refrigerant liquid, thereby converting into a refrigerant gas. In the process of converting the refrigerant liquid into the refrigerant gas, a large amount of heat is absorbed, so that the temperature of the purified water in the purified water storage device 310 is reduced, and the cold energy transfer is realized. The refrigerant gas may sequentially enter the compressor 321 through the outlet end of the evaporator 323 and the inlet end of the compressor 321, thereby performing a cycle.

With this arrangement, the refrigeration apparatus 320 can realize a refrigeration cycle of compression, condensation, expansion, and evaporation (heat absorption). The refrigerating device 320 is simple in structure, low in cost and good in refrigerating effect.

As an exemplary embodiment, evaporator 323 may include an evaporator coil, as shown in fig. 2-8. The structure of the evaporation coil can be any, such as a round pipe or a flat pipe. The evaporating coil may be wound around the outside of the purified water storage unit 310 in a circular manner. The evaporating coil can be abutted against the outer surface of the water purifying and storing device 310 and at least covers part of the outer surface of the water purifying and storing device 310. Through the arrangement, more refrigerants can be stored in the evaporator 323, and the cold transfer area between the evaporator 323 and the water purification and storage device 310 is larger, so that the cold transfer efficiency between the evaporator 323 and the purified water in the water purification and storage device 310 is higher. Moreover, the evaporator 323 has a simple structure and low cost. It should be understood that the above is only an example to illustrate one embodiment of the evaporator 323, and in other embodiments not shown, the evaporator 323 may be implemented in any other suitable manner.

As an exemplary embodiment, as shown in fig. 2 to 8, the water purifying and storing device 310 may have a longitudinal structure in a vertical direction. The evaporator 323 can be attached to the outside of the purified water storage unit 310. The compressor 321 may be fixedly coupled to the condenser 322. The compressor 321 and the condenser 322 which are fixedly connected together may be connected to one end of the purified water storage device 310 in the vertical direction through a rigid connection 340. Due to the arrangement, the cold water assembly 300 can be integrally distributed along the vertical direction, and the space in the horizontal direction cannot be additionally occupied, so that the whole cold water assembly 300 is compact in structure, the miniaturization design of the water purifier under a kitchen is facilitated, and the arrangement inside a cabinet of the kitchen is convenient. It should be understood that the horizontal direction may be at an angle to the vertical, for example, the horizontal direction is perpendicular to the vertical.

Illustratively, the rigid connection 340 may include a connecting rod, a connecting block, or the like. With this arrangement, the coupling strength between the compressor 321, the condenser 322, and the evaporator 323 is high. In addition, the compressor 321 and the condenser 322 can be directly and rigidly connected to be fixed on the water purifying and storing device 310, and a fixing structure is not required to be additionally arranged on the compressor 321 and the condenser 322, so that the overall structure of the cold water assembly 300 is simpler. Further, as shown in fig. 2-8, the rigid connector 340 may comprise a rigid tube. Rigid tubes may communicate between the outlet end of the condenser 322 and the inlet end of the evaporator 323, and/or between the outlet end of the evaporator 323 and the inlet end of the compressor 321. Like this, the rigid pipe both can play the effect of connecting fixedly, can also play the effect of transmission refrigerant to make the structure of purifier under the kitchen more succinct.

It is understood that the above is only an exemplary illustration of the structural layout of the refrigeration device, and the specific structure of the refrigeration device is not limited thereto in practical applications.

The structure of the water purifying assembly 200 will be exemplarily described below.

The water purification assembly 200 may include a booster pump 210 and a filtering device 220.

The booster pump 210 may be used to increase the water pressure. The booster pump 210 may be any of a variety of types known in the art or that may occur in the future. The booster pump 210 may be connected to a pipe between the water inlet of the filter device 220 and the water inlet end 110.

The filtering device 220 may be used to filter raw water to produce purified water. The filter device 220 may employ various types of filter devices known in the art or that may occur in the future. Illustratively, the filtering device 220 includes, but is not limited to, a filter screen, or a scale inhibitor, or a PP cotton filter element, or an activated carbon filter element, or a reverse osmosis filter element, or an ultrafiltration membrane filter element, or a composite filtering device formed by compounding any two or more of them.

When the under-kitchen water purifier works, water can enter the booster pump 210 through the water inlet end 110 in sequence. The pressurized high-pressure water passing through the booster pump 210 may enter the filter device 220 through the water inlet of the filter device 220. The purified water filtered by the filtering device 220 may sequentially pass through the water outlet and the water inlet of the filtering device 220 and enter the purified water storage device 310.

With this arrangement, the filter device 220 is simple in structure and low in cost.

In embodiments where the filtration device 220 includes a reverse osmosis filter element, pure water and wastewater may be produced simultaneously during filtration due to the reverse osmosis filter element. The pure water is the pure water with better water quality. The pure water can be directly drunk. The pure water may enter the pure water storage unit 310. The wastewater may be discharged out of the under-kitchen water purifier through the wastewater end 130 of the under-kitchen water purifier. The reverse osmosis filter element has higher filtering precision, and the water quality of the filtered pure water is better. It should be noted that the filtering apparatus 220 may include only the reverse osmosis filter element, or may include a composite filtering apparatus formed by combining the reverse osmosis filter element with the other filtering apparatuses.

In some exemplary embodiments, as shown in fig. 1-8, a waste solenoid valve 630 may be disposed in the conduit of the waste end 130. The waste water solenoid valve 630 is opened and closed to control the connection and disconnection of the waste water end 130, so as to achieve the purpose of waste water control.

Further, as shown in fig. 2-8, the under-kitchen water purifier may further include a middle frame 420. Illustratively, the middle frame 420 may be located inside the housing 410.
