Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a water supply system; the present application also relates to a refrigerator. Background Art

[0002] With improved living standards and heightened health awareness, people are increasingly demanding healthy drinking water. Water purifiers, ultrafiltration machines, RO machines, water softeners, chillers, and aerators are becoming increasingly popular. However, single water purifiers, chillers, or aerators are no longer sufficient to meet user needs. Therefore, integrated functions are needed to cool filtered water and inject gas to achieve better bubble generation and a better taste.

[0003] Both refrigerators and bubble machines are equipped with a compressor for cooling, which is relatively large. If the compressor is integrated into the water purifier, the resulting integrated device will be larger in size, making it inconvenient for users to install flexibly. In addition, users who already have a water purifier need to consider how to add a refrigerator or bubble machine to the existing water purifier. Therefore, how to connect the water circuits of the water purifier with other equipment and integrate their functions is a technical problem that needs to be solved urgently by those skilled in the art.

[0049] In addition, the total weight of the water purifier and refrigerator exceeds 28 kilograms. If they are integrated into one device, it will be difficult to carry, install and maintain. Therefore, integrating the water purification module, heating module, etc. into a water purifier device can meet the functional requirements of the water purifier working alone. Integrating the refrigeration module, bubble water making module, etc. into a refrigerator (bubble machine) device can achieve increased functionality by simply connecting the water lines through connecting pipes to meet the diverse needs of users. Moreover, the water purifier equipment and the refrigerator equipment basically share the weight, which will be much easier to carry, install and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] First, the terms involved in one or more embodiments of the present application are explained.

[0069] Water purifier: A machine used to purify water. A water purifier is a water treatment device that deeply filters and purifies water according to the requirements of water use.

[0070] Chiller: A machine used to cool or refrigerate water, producing chilled water. To achieve this, a chiller may be equipped with a compressor, which is typically large and heavy. Therefore, integrating the functions of a water purifier and a chiller into the same device would result in excessive size and weight, making installation difficult. When using the water purifier and chiller as two separate devices, functional integration requires designing the internal waterways of both devices to allow for interconnection.

[0071] In the present application, a water supply system and a refrigerator are provided, which are described in detail one by one in the following embodiments.

[0072] Example 1

[0073] refer to Figure 1 and Figure 2This embodiment provides a water supply system, including a water purifier 1, a refrigerator 2 and a connecting pipe 41. The water purifier 1 includes a first shell 18, and the first shell 18 is provided with a water inlet pipe, a filter assembly 12 and a liquid supply pipe that are connected in sequence. Figure 1 As shown, a water inlet 111 is provided on the first shell 18 , and a water source pipeline 40 is connected to the water inlet 111 . External water (such as tap water) can flow into the water source pipeline 40 and enter the water inlet pipeline inside the water purifier 1 through the water inlet 111 .

[0074] like Figure 2 As shown, the external water source from the water source pipeline 40 can enter the filter assembly 12 through the water inlet pipeline. The filter assembly 12 is used to filter the external water source from the water inlet pipeline and is configured to discharge the filtered water at room temperature through the liquid supply pipeline. Specifically, the filter assembly 12 can be a filter element dedicated to the water purifier. It is understood that the water filtered by the filter assembly 12 meets the standard for direct drinking. Figure 2 As shown, the liquid supply pipeline can be a series of pipelines connected after the filter assembly 12. The specific structure of the liquid supply pipeline will be described in detail later. Figure 1 The outlet of the liquid supply pipeline is the first interface 112 on the water purifier 1, and the filtered room temperature water can be discharged from the water purifier 1 through the first interface 112.

[0075] refer to Figure 1 and Figure 2 The refrigerator 2 includes a second housing 27, in which a liquid inlet pipeline is provided. The liquid inlet pipeline is configured to communicate with the liquid supply pipeline. Figure 1 As shown, the water supply system also includes a connecting pipe 41, which is arranged outside the first shell 18 and the second shell 27, and is configured to connect the liquid inlet pipe and the liquid supply pipe, thereby connecting the water circuits of the two independent devices, the water purifier 1 and the refrigerator 2. Specifically, the inlet of the liquid inlet pipe is the second interface 211 on the refrigerator 2. A connecting pipe 41 is provided between the water purifier 1 and the refrigerator 2. One end of the connecting pipe 41 is connected to the first interface 112, and the other end is connected to the second interface 211, so that the normal temperature water discharged from the water purifier 1 flows into the connecting pipe 41 and enters the interior of the refrigerator 2 through the second interface 211.

[0076] refer to Figure 2 The refrigerator 2 also includes a refrigeration assembly 22 and a water outlet pipeline. The refrigeration assembly 22 is arranged at a downstream position of the liquid inlet pipeline so as to process the room temperature water flowing into the refrigerator 2. At least part of the room temperature water is configured to flow into the refrigeration assembly 22 through the liquid inlet pipeline to be cooled and generate cold water. The water outlet pipeline is constructed to communicate with the refrigeration assembly 22 so that the cold water can be discharged from the water outlet pipeline to the outside of the refrigerator 2. Figure 1The refrigerator 2 is also provided with a water outlet 212, which is the outlet of the liquid in the refrigerator 2. The water outlet pipeline can connect the refrigeration component 22 with the water outlet 212, so that cold water can be discharged from the water outlet 212.

[0077] The present application provides a water supply system that integrates the functions of a water purifier 1 and a refrigerator 2. The liquid inlet pipeline and the liquid supply pipeline are connected through a connecting pipeline 41 provided outside the housings of the two devices, thereby connecting the water circuits of the water purifier 1 and the refrigerator 2. After the water purifier 1 has finished filtering, clean water at room temperature can flow into the refrigerator 2 to generate cold water. The refrigeration component 22 for cooling in the refrigerator 2 may include a compressor. The larger compressor does not need to be integrated into the water purifier 1. Instead, the functions of the two independent devices, the water purifier 1 and the refrigerator 2, are integrated in series to achieve the desired effect.

[0078] The water purifier 1 and refrigerator 2 of the present application are two independently installed devices, and each of the two devices is relatively small, making it easy for users to install them flexibly. When the user's installation space is small, they can choose to purchase only the water purifier 1 to meet the needs of healthy drinking water. When the user's installation space is sufficient, they can choose to add refrigerator 2 to enrich the taste of drinking water. It can be seen that the water supply system provided by the present application allows users to choose equipment more flexibly. Users can selectively purchase equipment according to their own needs and the size of the reserved installation space, thereby improving the user experience.

[0079] In addition, the total weight of the water purifier 1 and the refrigerator 2 exceeds 28 kilograms. If they are integrated into one device, it will be difficult to carry, install and maintain. Therefore, the water purification module, heating module, etc. are integrated into a water purifier 1 device to meet the functional requirements of the water purifier 1 working alone. The refrigeration module, bubble water making module, etc. are integrated into a refrigerator (bubble machine) device. Only by connecting the water pipes to connect the water channels can the functions be increased to meet the diversified needs of users. Moreover, the water purifier 1 device and the refrigerator 2 device basically share the weight, which will be much lighter during transportation, installation and maintenance.

[0080] In one embodiment of the present application, Figure 2As shown, a carbonization component 23 is also provided in the second housing 27 of the refrigerator 2, and at least a portion of the cold water is configured to flow into the carbonization component 23 to mix with carbon dioxide to generate sparkling water; the water outlet pipe is constructed to communicate with the carbonization component 23. It should be noted that the solubility of carbon dioxide in cold water is relatively high, which is more conducive to the production of sparkling water. Therefore, only the cold water cooled by the refrigeration component 22 will partially enter the carbonization component 23, while water at room temperature will not directly flow into the carbonization component 23. It can be understood that the refrigerator 2 in this embodiment is a sparkling machine. By adding the carbonization component 23 inside the refrigerator 2, the refrigerator 2 can not only produce cold water, but also further process the cold water into sparkling water, thereby enriching the user's drinking taste and improving the user experience.

[0081] In one embodiment of the present application, reference Figure 1 and Figure 2 , the water supply system also includes a liquid outlet device 3, and the liquid outlet device 3 in this application can be understood as a faucet. The liquid outlet device 3 is configured to be connected to the water outlet pipeline of the refrigerator 2 through the liquid outlet pipeline 43, and / or, to be connected to the liquid supply pipeline of the water purifier 1 through the normal temperature water pipeline. For the normal temperature water in the water purifier 1, it can flow directly to the liquid outlet device 3 through the normal temperature water pipeline for discharge, or it can flow to the refrigerator 2 through the liquid supply pipeline and the connecting pipeline 41. The refrigerator 2 can transport the cold water generated by the refrigeration component 22 to the liquid outlet device 3 for discharge through the liquid outlet pipeline 43, and can also transport the bubble water generated by the carbonization component 23 to the liquid outlet device through the liquid outlet pipeline 43 for discharge.

[0082] In a specific embodiment of the present application, the refrigerator 2 can also directly deliver room temperature water to the liquid outlet device 3 through the liquid outlet pipeline 43. Specifically, Figure 2 As shown, the water outlet pipeline is constructed to communicate with the liquid inlet pipeline, the refrigeration assembly 22, and the carbonization assembly 23. For room-temperature water flowing into the liquid inlet pipeline, it can flow directly to the water outlet pipeline or to the refrigeration assembly 22. For cold water produced by the refrigeration assembly 22, it can flow directly to the water outlet pipeline or to the carbonization assembly 23. For sparkling water produced by the carbonization assembly 23, it can only flow to the water outlet pipeline.

[0083] refer to Figure 1 , the liquid outlet device 3 is constructed to discharge normal temperature water, cold water, and bubble water respectively under the control of the control valve assembly. The liquid in the refrigerator 2 can flow to the liquid outlet device 3. Specifically, the normal temperature water, cold water, and bubble water in the refrigerator 2 can all flow to the water outlet 212 through the water outlet pipeline, and enter the liquid outlet device 3 through the liquid outlet pipeline 43. The liquid outlet device 3 in the present application can be a faucet with multiple water outlet modes. The user can choose the water outlet type according to their own needs, and control the liquid outlet device 3 to discharge normal temperature water, cold water, or bubble water through the faucet gear, button, remote control, etc.

[0084] Next, the detailed internal structures of the refrigerator 2 and the water purifier 1 will be introduced in turn.

[0085] In one embodiment of the present application, Figure 2 As shown, the refrigerator 2 includes a first pipeline for connecting the liquid inlet pipeline and the refrigeration assembly 22. The control valve assembly includes a first control valve 201 disposed in the first pipeline. The first control valve 201 is configured so that when it is opened, normal temperature water is configured to flow from the liquid inlet pipeline to the refrigeration assembly 22. The first pipeline is the pipeline used to connect the second interface 211 and the refrigeration assembly 22. The first control valve 201 can be used to control the connection or closure of the first pipeline. When the first control valve 201 is opened, the first pipeline is connected, and the normal temperature water in the liquid inlet pipeline flows into the refrigeration assembly 22 through the first pipeline for refrigeration; when the first control valve 201 is closed, the first pipeline is closed, and the normal temperature water in the liquid inlet pipeline cannot flow into the refrigeration assembly 22, but can only remain stationary or flow in other directions.

[0086] The refrigerator 2 also includes a second pipeline for connecting the liquid inlet pipeline and the water outlet pipeline. The control valve assembly includes a second control valve 202 disposed in the second pipeline. The second control valve 202 is configured so that when it is opened, the normal temperature water is configured to flow from the liquid inlet pipeline to the water outlet pipeline. The second pipeline is a pipeline for connecting the second interface 211 and the water outlet pipeline. The second control valve 202 can be used to control the connection or closure of the second pipeline. When the second control valve 202 is opened, the second pipeline is connected, and the normal temperature water in the liquid inlet pipeline flows to the water outlet pipeline through the second pipeline; when the second control valve 202 is closed, the second pipeline is closed, and the normal temperature water in the liquid inlet pipeline cannot flow to the water outlet pipeline, but can only remain stationary or flow in other directions.

[0087] like Figure 2 As shown, the first pipeline and the second pipeline are interconnected. When the first control valve 201 and the second control valve 202 are opened at the same time, the normal temperature water will flow to the refrigeration component 22 and the water outlet pipeline. When the first control valve 201 is opened and the second control valve 202 is closed, the normal temperature water will flow to the refrigeration component 22. When the first control valve 201 is closed and the second control valve 202 is opened, the normal temperature water will flow to the water outlet pipeline. When the first control valve 201 and the second control valve 202 are closed at the same time, the normal temperature water can only remain in the liquid inlet pipeline and cannot flow further into the refrigerator 2. It can be seen that the present application realizes the control of the flow direction of the normal temperature water entering the refrigerator 2 by providing the first control valve 201 and the second control valve 202.

[0088] In one embodiment of the present application, continue to refer to Figure 2The water outlet pipeline is configured to communicate with the refrigeration assembly 22 and the carbonation assembly 23 through a third pipeline and a fourth pipeline, respectively. The control valve assembly includes a third control valve 203 and a fourth control valve 204, respectively disposed in the third pipeline and the fourth pipeline. When the third control valve 203 is opened, cold water is configured to flow from the refrigeration assembly 22 to the water outlet pipeline; when the fourth control valve 204 is opened, sparkling water is configured to flow from the carbonation assembly 23 to the water outlet pipeline.

[0089] The third pipeline connects the refrigeration unit 22 and the water outlet pipeline. The third control valve 203 controls whether the third pipeline is connected or closed. When the third control valve 203 is open, the third pipeline is connected, allowing the cold water in the refrigeration unit 22 to flow into the water outlet pipeline. When the third control valve 203 is closed, the third pipeline is closed, preventing the cold water in the refrigeration unit 22 from flowing out and forcing it to remain stationary or flow in other directions.

[0090] The fourth pipeline connects the carbonation assembly 23 and the water outlet pipeline. The fourth control valve 204 controls the connection or blocking of the third pipeline. When the fourth control valve 204 is open, the fourth pipeline is connected, allowing the bubbled water in the carbonation assembly 23 to flow into the water outlet pipeline. When the fourth control valve 204 is closed, the fourth pipeline is blocked, preventing the bubbled water in the carbonation assembly 23 from flowing out and forcing it to remain stationary or flow in other directions.

[0091] Both the refrigeration assembly 22 and the carbonization assembly 23 may include containers with water storage functions, for storing a certain amount of cold water and sparkling water, respectively. Thus, when the user needs cold water, they only need to control the third control valve 203 to open, and cold water will flow out of the liquid outlet 3; when the user needs sparkling water, they only need to control the fourth control valve 204 to open, and sparkling water will flow out of the liquid outlet 3. When the user needs room-temperature water, they not only need to control the aforementioned second control valve 202 to open, but also need to control the relevant control valve components in the water purifier 1 to open, so that the room-temperature water is first filtered by the water purifier 1, then flows into the refrigeration unit 2, and then flows out of the liquid outlet 3.

[0092] In a specific embodiment, Figure 2 As shown, a damping valve 207 can be installed in the fourth pipeline, located between the fourth control valve 204 and the carbonization assembly 23. Those skilled in the art will appreciate that the air pressure within the carbonization assembly 23 is relatively high. Therefore, when the fourth control valve 204 is opened, the bubbled water may be ejected from the liquid outlet device 3 under the action of pressure, resulting in a poor user experience. The damping valve 207 can slow the flow rate of the bubbled water in the fourth pipeline, allowing the bubbled water to flow out of the liquid outlet device 3 at a normal rate, thereby improving the user experience.

[0093] In one embodiment of the present application, reference Figure 2 , the pipelines between the liquid inlet pipeline, the refrigeration component 22, the carbonization component 23 and the water outlet pipeline are constructed to be connected to the water outlet pipeline through a multi-way pipe joint 25. That is to say, the second pipeline, the third pipeline, and the fourth pipeline mentioned above are all connected to the multi-way pipe joint 25, and can respectively transport normal temperature water, cold water, and bubble water to the multi-way pipe joint 25. The multi-way pipe joint 25 is also connected to the water outlet pipeline, and the normal temperature water, cold water, and bubble water flowing into the multi-way pipe joint 25 will continue to flow to the water outlet pipeline and be discharged from the liquid outlet device 3 through the liquid outlet pipeline 43. Specifically, the multi-way pipe joint 25 can be a four-way joint, or it can be formed by connecting two three-way joints. The present application does not limit the specific structure of the multi-way pipe joint 25. The present application simplifies the water path layout inside the refrigerator 2 by providing a multi-way pipe joint 25. Specifically, the second pipe, the third pipe, and the fourth pipe can converge at the multi-way pipe joint 25, so that normal temperature water, cold water, and bubble water share the section of pipe between the multi-way pipe joint 25 and the water outlet 212, shortening the total length of the pipes inside the refrigerator 2 and optimizing the spatial layout inside the refrigerator 2.

[0094] In one embodiment of the present application, reference Figure 2 and Figure 4 The refrigeration component 22 includes a cold water tank 221, which is used to cool liquid and includes an inlet of the cold water tank 221 and an outlet of the cold water tank 221. The inlet of the cold water tank 221 is constructed to be connected to the liquid inlet pipeline; the outlet of the cold water tank 221 is configured to be connected to the water outlet pipeline and the carbonization component 23 respectively. Specifically, the inlet of the cold water tank 221 is connected to the liquid inlet pipeline through a first pipeline, and the outlet of the cold water tank 221 is connected to the water outlet pipeline through a third pipeline. The cold water tank 221 is the main structure of the refrigeration component 22. Normal temperature water flows into the inlet of the cold water tank 221 and is cooled and refrigerated in the cold water tank 221. The cold water generated by the cooling can be stored in the cold water tank 221 for use at any time. The cold water tank 221 can have a large capacity, so that the user can release more cold water at one time.

[0095] In a specific embodiment of the present application, the refrigeration assembly 22 may further include a compressor 222, a condenser 223, a fan 224, and an evaporator 225, wherein the compressor 222 can increase the refrigerant pressure from low to high pressure; the condenser 223 can cool the high-temperature and high-pressure refrigerant discharged from the compressor 222 into liquid; the fan 224 can increase air flow, thereby promoting the heat exchange efficiency of the condenser 223; the evaporator 225 is arranged in the cold water tank 221, and the evaporator 225 can convert the high-temperature and high-pressure refrigerant into a low-temperature and low-pressure state, thereby cooling the liquid in the cold water tank 221. The above-mentioned components enable the refrigerant to circulate continuously, thereby continuously discharging the heat in the cold water tank 221 to the outside to a higher temperature environment.

[0096] When the first control valve 201 is open, the room-temperature water in the liquid inlet line can flow from the inlet of the cold water tank 221 into the cold water tank 221 for cooling. The cold water generated by the cooling can flow in two directions: to the outlet line, or to the carbonization assembly 23. As mentioned above, controlling the third control valve 203 to open allows the cold water to flow out of the outlet of the cold water tank 221. When the third control valve 203 is closed, due to the large amount of carbon dioxide inside the carbonization assembly 23, its internal pressure is higher than that of the cold water tank 221. Therefore, the cold water cannot spontaneously flow to the carbonization assembly 23 and needs to use other power structures.

[0097] In order to allow cold water to flow to the carbonization assembly 23, in one embodiment of the present application, the refrigerator 2 further includes a pump body, which is configured to pump the cold water in the cold water tank 221 to the carbonization assembly 23 and the water outlet pipe; when the control valve assembly opens the pipe between the cold water tank 221 and the water outlet pipe, the water outlet pressure from the pump body through the water outlet pipe to the liquid outlet device 3 is lower than the water outlet pressure from the pump body to the carbonization assembly 23. Figure 2 As shown, the pump body can be a booster pump 24, which is arranged on the third pipeline and located upstream of the third control valve 203. The booster pump 24 is used to pump the cold water flowing out of the cold water tank 221 along the third pipeline to the water outlet pipeline, and pump the cold water to the carbonization assembly 23.

[0098] Specifically, when the boost pump 24 and the third control valve 203 are both closed, the cold water in the cold water tank 221 will not flow out. When the boost pump 24 and the third control valve 203 are both open, the cold water in the cold water tank 221 will flow to the water outlet pipe at a higher flow rate under the action of the boost pump 24, thereby making the cold water outlet speed of the liquid outlet device 3 sufficiently large; at the same time, due to the high air pressure inside the carbonization component 23, the cold water will only flow to the water outlet pipe with lower pressure. When the boost pump 24 is turned on and the third control valve 203 is closed, the pressure provided by the boost pump 24 can overcome the pressure inside the carbonization component 23, and the cold water in the cold water tank 221 will be pumped into the carbonization component 23 under the action of the boost pump 24. By arranging a pump body on the third pipeline, the present application simultaneously achieves the two functions of discharging cold water and filling the carbonization component 23 with water, using one pump for two purposes, saving components in the refrigerator 2 and improving the economic efficiency of the refrigerator 2.

[0099] In one embodiment of the present application, reference Figure 2The carbonization assembly 23 includes a carbonization tank 231 and a carbon dioxide gas source 232. The carbon dioxide gas source 232 is configured to deliver carbon dioxide gas into the carbonization tank 231. The carbonization tank 231 is the main structure of the carbonization assembly 23. Cold water flows into the carbonization tank 231 from the inlet and mixes with carbon dioxide in the carbonization tank 231 to generate sparkling water. The sparkling water can be stored in the carbonization tank 231 for ready use. In a specific embodiment, a distributor can be provided at the inlet of the carbonization tank 231 to evenly spray cold water into the carbonization tank 231, thereby evenly mixing the cold water and carbon dioxide, thereby increasing the gas content in the sparkling water.

[0100] A pressure reducing valve 233, a pressure switch 234, and an air injection valve 235 are provided on the gas supply line between the carbon dioxide gas source 232 and the carbonization tank 231. The air injection valve 235 is a one-way valve, allowing the carbon dioxide gas source 232 to deliver carbon dioxide to the carbonization tank 231 in a one-way manner, while preventing the gas-liquid mixture in the carbonization tank 231 from flowing into the carbon dioxide gas source 232. The air injection valve 235 can be positioned near the carbonization tank 231, ensuring that only carbon dioxide gas flows in the gas supply line and is not contaminated by the gas-liquid mixture in the carbonization tank 231. The carbon dioxide gas source 232 and the carbonization tank 231 are connected via the pressure reducing valve 233 and are configured to be in a normally open state. The pressure inside the carbonization tank 231 is monitored in real time by the pressure switch 234 to maintain the pressure within the tank at 4±0.5 Bar. This ensures that the pressure in the carbonization tank 231 is sufficiently high, thereby ensuring that when the boost pump 24 and the third control valve 203 are opened at the same time, the cold water will only flow to the water outlet pipe and will not flow into the carbonization tank 231.

[0101] like Figure 2 As shown, a one-way valve 208 is provided in the pipeline between the carbonizing tank 231 and the pump body, and the one-way valve 208 is configured to cut off the pipeline in which the gas and liquid in the carbonizing tank 231 flow in the direction of the pump body. The one-way valve 208 provided between the carbonizing tank 231 and the booster pump 24 enables the cold water tank 221 to deliver cold water to the carbonizing tank 231 in a one-way direction, while the bubble water in the carbonizing tank 231 does not flow to the cold water tank 221. It is understandable that the pressure in the carbonizing tank 231 is relatively high. If the one-way valve 208 is not provided, the bubble water in the carbonizing tank 231 may flow to the cold water tank 221 under pressure, thereby causing contamination of the cold water tank 221. The present application cuts off the pipeline for the bubble water to flow out by providing a one-way valve 208 between the carbonizing tank 231 and the booster pump 24, thereby preventing the cold water tank 221 from being contaminated.

[0102] In one embodiment of the present application, Figure 1As shown, the refrigerator 2 is also provided with an external water outlet 216, which can be used to discharge room temperature water and supply water to other external devices 7. The external device 7 can be various devices that require water, such as cooking equipment, cleaning equipment, humidifiers, water heaters, etc. For example, if the external device 7 is a cooking device, the cooking device often needs to be added with water during the cooking process, and purified water needs to be added to ensure the quality of the dishes. If it is very troublesome for the user to manually add water many times during the cooking process, the cooking device can be directly connected to the refrigerator 2, so as to realize automatic water supply and improve the user experience. Similarly, the water purifier 1 can also be provided with a second external water outlet for supplying water to the external device 7, so that the external device 7 can be automatically supplied with water when the water purifier 1 is used alone.

[0103] Specifically, if Figure 1 As shown, the external water outlet 216 can be connected to the external device 7 through the external water supply pipe 44 and supply water to the external device 7. Figure 2 As shown, the first control valve 201 is constructed as a one-inlet, two-outlet solenoid valve, with its inlet connected to the second interface 211, and its two outlets connected to the refrigeration assembly 22 and the external water outlet 216, respectively. When the first control valve 201 is opened to the first position, which connects the second interface 211 with the refrigeration assembly 22, the room-temperature water flowing into the refrigerator 2 from the second interface 211 can flow to the refrigeration assembly 22; when the first control valve 201 is opened to the second position, which connects the second interface 211 with the external water outlet 216, the room-temperature water flowing into the refrigerator 2 from the second interface 211 can be discharged from the external water outlet 216 and flow to the external device 7.

[0104] The above describes the internal structure and water channel arrangement of the refrigerator 2 of this embodiment. Next, the internal structure and water channel arrangement of the water purifier 1 of this embodiment will be introduced.

[0105] refer to Figure 2 The water purifier 1 is provided with a water inlet valve 101 and a water inlet pump 17, which can be arranged upstream of the filter assembly 12. When the water purifier 1 needs water, the water inlet valve 101 and the water inlet pump 17 are opened simultaneously, and the external water source flows into the water purifier 1 through the water source pipeline 40 and the water inlet pipeline under the action of the water inlet pump 17, and then flows into the filter assembly 12 for filtration.

[0106] The water purifier 1 is also provided with a waste liquid pipeline 14 connected to the filter assembly 12, and a waste water valve 102 is provided on the waste liquid pipeline 14. Those skilled in the art will appreciate that during the filtration process of the filter assembly 12, the filter assembly 12 will produce a certain proportion of waste water. The waste liquid pipeline 14 leads to the outside of the water purifier 1, specifically, it can be directly connected to the sewer to discharge the waste water. The waste water valve 102 can be kept in a normally open state. As long as the filter assembly 12 starts filtering and produces waste water, the waste water can be discharged directly through the waste liquid pipeline 14.

[0107] A pure water valve 103 is provided on the liquid supply pipeline in the water purifier 1, and the pure water valve 103 is provided between the filter assembly 12 and the first interface 112. When the pure water valve 103 is opened, the room temperature water flowing out of the filter assembly 12 can flow to the first interface 112 and can flow into the refrigerator 2 through the connecting pipeline 41.

[0108] In a specific embodiment, when the user needs to connect to room temperature water, the water purifier 1 and the refrigerator 2 start working at the same time: the water inlet valve 101, the water inlet pump 17, and the pure water valve 103 in the water purifier 1 are opened, so that the external water source flows to the filter component 12, and the room temperature water filtered by the filter component 12 flows to the refrigerator 2; the second control valve 202 in the refrigerator 2 is opened, so that the room temperature water flowing into the refrigerator 2 continues to flow to the water outlet pipeline, and is transported to the liquid outlet device 3 through the liquid outlet pipeline 43 for discharge.

[0109] In one embodiment of the present application, reference Figure 1 and Figure 2 The water purifier 1 is equipped with a heating assembly 13 and a hot water outlet 113. The heating assembly 13 is configured to heat filtered room-temperature water into hot water. The hot water outlet 113 is connected to the liquid outlet device 3 via a hot water pipe 42, so that the hot water can be discharged through the liquid outlet device 3. Specifically, the heating assembly 13 includes a heat source 131 and a hot water pump 132. A heat source fill valve 105 is provided between the filter assembly 12 and the heat source 131. When the heat source fill valve 105 is opened, filtered room-temperature water can flow into the heat source 131, where it is heated. The heated hot water is then stored within the heat source 131 for ready use. The heat source 131 can have a large capacity, allowing the user to dispense more hot water at once. The heat source 131 can have an exhaust vent to discharge steam generated during the heating process out of the water purifier 1. The exhaust vent can be connected to the atmosphere via an exhaust pipe 16 to discharge steam from the heat source 131.

[0110] When the user needs to connect to hot water, the hot water pump 132 located downstream of the outlet of the heat tank 131 starts working and pumps the hot water toward the hot water outlet 113. The hot water flows through the hot water pipe 42 to the liquid outlet device 3 and is discharged. The hot water pipe 42 needs to be made of heat-resistant material. By providing the heating component 13 in the water purifier 1, the user can freely control the liquid outlet device 3 to discharge normal temperature water, cold water, hot water, or sparkling water, thereby further improving the user experience.

[0111] After the liquid outlet device 3 finishes draining, there is residual liquid from the previous water use in the water supply system pipeline, which will cause the liquid outlet device 3 to first flow out the residual liquid when the user uses the water next time; in addition, when the liquid outlet device 3 has finished discharging the bubble water, there is still high-pressure gas in the pipeline, which will cause the liquid outlet device 3 to continue dripping, resulting in a poor user experience.

[0112] In order to avoid the problems of residue and dripping, two solutions are provided in this embodiment:

[0113] In one embodiment of the present application, the water supply system includes a drainage pipeline, such as Figure 2 As shown, the drainage pipeline can be the drainage pipeline 15 in the water purifier 1. After the liquid outlet device 3 is drained, the control valve assembly is configured to open the pipeline between the liquid outlet device 3, the water outlet pipeline, the liquid inlet pipeline, and the drainage pipeline. At least part of the liquid remaining in the pipeline between the liquid outlet device 3 and the liquid inlet pipeline, the refrigeration component 22 or the carbonization component 23 is configured to be discharged through the drainage pipeline. Specifically, a drain valve 104 is provided on the drainage pipeline 15. When the drainage is completed, the drain valve 104, the pure water valve 103 and the second control valve 202 are all in the open state. All other valves that are open during the drainage process are closed. During the drainage process, the liquid in the downstream pipeline can flow in the direction of passing through the second control valve 202, the pure water valve 103 and the drain valve 104 in sequence to flow back to the drainage pipeline 15 of the water purifier 1 for discharge. It should be noted that the drainage pipeline 15 and the waste liquid pipeline 14 can be the same pipeline or two pipelines set separately. The drainage pipe 15 can drain the residual water in the pipe to the sewer outside the water purifier 1, thus avoiding the problem of residue and dripping. If the residual water is returned to a sealed container, it may cause the container to fill up with water if the residual water volume is large or after multiple backflow operations. However, the present embodiment returns the residual water to the drainage pipe 15 for discharge without being affected by the residual water volume or the number of backflow operations.

[0114] In another embodiment of the present application, after the liquid outlet device 3 is drained, the control valve assembly is configured to open the pipelines between the liquid outlet device 3, the liquid outlet pipeline 43, the water outlet pipeline, the liquid inlet pipeline, and the refrigeration assembly 22. At least a portion of the liquid remaining in the pipelines between the liquid outlet device 3 and the liquid inlet pipeline, the refrigeration assembly 22, or the carbonization assembly 23 is configured to flow back to the refrigeration assembly 22. When the draining is completed, the second control valve 202 and the first control valve 201 are opened simultaneously, wherein the first control valve 201 is configured to open to the first position, that is, the position connecting to the refrigeration assembly 22. All other valves open during the draining process are closed. During the draining process, the liquid in the downstream pipeline can flow in a direction passing through the second control valve 202 and the first control valve 201 in sequence, and then enter the cold water tank 221 through the backflow. The residual liquid flowing back into the cold water tank 221 has a lower temperature, so almost no additional cooling consumption is required. Moreover, this solution solves the problem of residual and dripping liquid without adding a drainage pipeline 15 device to the water purifier 1, saving space and cost.

[0115] Specifically, the liquid outlet of the liquid outlet device 3 is constructed to be normally open to the outside world, and at least part of the liquid remaining in the pipeline between the liquid outlet device 3 and the liquid inlet pipeline, the refrigeration component 22 or the carbonization component 23 is configured to flow back into the refrigeration component 22 under the action of the external atmospheric pressure. The liquid outlet device 3 that is normally open to the outside world can be an electrically controlled smart faucet. The liquid outlet of the smart faucet does not need to be closed. By manipulating the opening and closing of the above-mentioned control valves, it is possible to control the water flow, water stop, and the type of water output of the faucet. After the liquid outlet device 3 that remains connected to the atmosphere stops discharging liquid, no negative pressure will be formed in the pipeline, and a communicating vessel can be formed, thereby allowing at least part of the liquid remaining in the pipeline between the liquid outlet device 3 and the liquid inlet pipeline, the refrigeration component 22 or the carbonization component 23 to flow back into the refrigeration component 22 under the action of the external atmospheric pressure.

[0116] In a specific embodiment of the present application, the multi-way pipe joint 25 is arranged in a position higher than the refrigeration assembly 22 in the refrigerator 2. In actual application scenarios, users usually place the water purifier 1 and the refrigerator 2 in a low position, such as a cabinet, and the liquid outlet device 3 is usually placed in a position higher than the water purifier 1 and the refrigerator 2, such as a sink or a countertop. Inside the refrigerator 2, the refrigeration assembly 22 is located at the bottom, wherein the compressor 222 in the refrigeration assembly 22 is located at the bottom, and the cold water tank 221 can be placed above the compressor 222. The multi-way pipe joint 25 is located above the cold water tank 221.

[0117] When cold water needs to be discharged, the cold water in the cold water tank 221 is pumped upward into the multi-way pipe joint 25 by the booster pump 24, and then continues to be pumped upward into the liquid outlet pipe 43, flowing all the way up to the liquid outlet device 3. The same principle applies to discharging other types of water, requiring the liquid to be pumped upward into the multi-way pipe joint 25, the liquid outlet pipe 43, and the liquid outlet device 3, which will not be described in detail here. When the water is discharged, the second control valve 202 and the first control valve 201 are opened simultaneously, allowing at least a portion of the liquid remaining in the pipeline between the liquid outlet device 3 and the liquid inlet pipe, refrigeration assembly 22, or carbonization assembly 23 to flow back downward under the influence of atmospheric pressure and gravity. Based on the principle of communicating vessels, the residual liquid will flow back to a position where its liquid level is flush with the liquid level in the cold water tank 221. This can be done by flowing back into the cold water tank 221 or by flowing back into a pipe below the liquid level in the cold water tank 221. It is understandable that when the position of the pipe into which the residual liquid flows is lower than the liquid level in the cold water tank 221, the liquid will not be able to continue to flow along the pipe and will remain in the pipe. Therefore, in order to ensure the best reflux effect, all pipes through which the reflux flows need to be set at a position higher than the cold water tank 221, so that all residual liquid can flow back into the cold water tank 221.

[0118] The above describes the waterway arrangement of the water purification system of this embodiment. It is understood that in addition to the waterway connection, other connections are also provided between the water purifier 1 and the chiller 2, thereby more completely constituting the water supply system of this application. The following describes the circuit connection method and the communication connection method between the water purifier 1 and the chiller 2.

[0119] In one embodiment of the present application, reference Figure 1 The water purifier 1 is provided with a first power circuit and a first power supply circuit; the refrigerator 2 is provided with a second power circuit; the first power circuit is constructed as an external power supply; the power supply circuit is constructed to be connected to the second power circuit to supply power to the refrigerator 2 through the water purifier 1. Figure 1 As shown, the water purifier 1 is provided with a first power inlet 114 and a power supply unit 115, and the refrigerator 2 is provided with a second power inlet 213. The first power inlet 114 is connected to the socket 50 via a first power cord 51, and the socket 50 can power the water purifier 1 via the first power cord 51; the second power inlet 213 is connected to the power supply unit 115 via a second power cord 52, and the power supply unit 115 can power the refrigerator 2 via the second power cord 52, thus simplifying the circuit connection of the water supply system.

[0120] In actual installation scenarios, users may only have one socket 50 reserved, for example, inside a cabinet. If two devices need to be installed, an additional power strip needs to be installed to increase the socket. The design of this application solves the above problem well. This application provides a power supply unit 115 on the water purifier 1, and supplies power to the refrigerator 2 through the water purifier 1, thereby making the water supply system of this application easier to install. It is possible to power two devices simultaneously through one socket 50, thereby improving the user's installation experience.

[0121] In one embodiment of the present application, the water purifier 1 is constructed to be communicatively connected with the refrigerator 2, and the refrigerator 2 is constructed to be communicatively connected with the liquid outlet device 3. It should be noted that the communication connection here can be wired control or wireless control, and this application does not limit this. The water supply system includes a control unit, which can be used to control the liquid outlet device 3 of the water supply system to perform water outlet and water shut-off operations, and can be used to select the type of water outlet, and can also have multiple other functions. The control unit can be set on any one or more of the water purifier 1, refrigerator 2, and liquid outlet device 3. The control unit can also be the user's mobile phone, and the user can remotely control the water supply system.

[0122] Specifically, such as Figure 1 As shown, the water purifier 1 is provided with a first wiring port 116, the refrigerator 2 is provided with a second wiring port 214 and a third wiring port 215, and the liquid outlet device 3 is provided with a fourth wiring port 31. The first wiring port 116 is connected to the second wiring port 214 via a first control line 61, and the third wiring port 215 is connected to the fourth wiring port 31 via a second control line 62, thereby achieving a communication connection between the water purifier 1 and the refrigerator 2, and a communication connection between the refrigerator 2 and the liquid outlet device 3. In this connection mode, regardless of whether the control unit is set on the water purifier 1, the refrigerator 2 or the liquid outlet device 3, the interconnection control of the three can be achieved. Moreover, the communication connection mode of the present application is simple, the user can disassemble and assemble it by himself, and it is also convenient for subsequent maintenance.

[0123] Example 2

[0124] This embodiment also provides a water supply system, which differs from the first embodiment only in that an additional drain line 26 is provided in the refrigerator 2. Specifically, this embodiment provides a new solution to the problem of water residue in the line and dripping from the liquid outlet device 3 by providing the drain line 26.

[0125] refer to Figure 3, the drain line is arranged in the liquid supply line, and the control valve assembly is configured to control at least part of the liquid remaining in the line to be discharged from the liquid inlet line and the drain line to the outside world under the external atmospheric pressure. The drain line in this embodiment is the liquid outlet line 43. Specifically, the drain line 26 can be connected to the third line, and the connection position of the two can be located between the booster pump 24 and the refrigeration device 22. A pre-valve 205 can also be provided between the connection position and the refrigeration device 22, and a drain valve 206 is provided on the drain line 26. When the drain valve 206 is opened, one end of the drain line 26 is connected to the atmosphere.

[0126] When cold water needs to be released, the pre-valve 205, booster pump 24, and third control valve 203 are all opened, thereby pumping the cold water outward. When releasing other types of water, the opening and closing methods of the various pumps and valves in the water supply system are exactly the same as those in Example 1. Continuing with the cold water release scenario as an example, when the water is no longer released, only the pre-valve 205 is closed, while the booster pump 24 and third control valve 203 remain open, and the cold water no longer flows out. At the same time, the drain valve 206 is opened, and the booster pump 24 draws in the external atmosphere, which is then discharged from the liquid outlet device 3 along the liquid inlet and outlet pipes 43 to the outside world. This ensures that the water in the pipeline can be completely emptied to the greatest extent possible, ensuring that no water remains in the pipeline, thereby solving the problem of residual water and dripping.

[0127] Example 3

[0128] This embodiment also provides a water supply system, which differs from the first embodiment only in the arrangement of the cold water tank 221 and the carbonization tank 231 in the refrigerator 2.

[0129] refer to Figure 4 In this embodiment, the carbonization tank 231 is at least partially arranged in the cold water tank 221. The carbonization tank 231 can only expose the top for connecting other pipelines outside the cold water tank 221, and the rest of the parts can be placed inside the cold water tank 221. The cold water tank 221 and the carbonization tank 231 together constitute a "tank in a tank" structure. The temperature inside the cold water tank 221 is low and continuously cooled. Therefore, the carbonization tank 231 can be insulated by the cold water tank 221, so that the sparkling water provided by the water supply system has a better taste. Specifically, when the "tank in a tank" structure is used for insulation, the user can continuously release approximately 1.3L of relatively constant temperature (water temperature fluctuation range ±1 degree) sparkling water, which improves the user experience.

[0130] Example 4

[0131] This embodiment provides a refrigerator 2 comprising a housing, within which are disposed: a liquid inlet pipeline, a refrigeration assembly 22, and a water outlet pipeline. The liquid inlet pipeline is configured to connect to a water purifier 1, and the refrigeration assembly 22 is configured to communicate with the liquid inlet pipeline. Normal-temperature water flowing out of the water purifier 1 is configured to flow through the liquid inlet pipeline into the refrigeration assembly 22 for cooling and generating cold water. The water outlet pipeline is configured to communicate with the refrigeration assembly 22 to discharge the cold water through the water outlet pipeline.

[0132] In one embodiment of the present application, a carbonization assembly 23 is further provided in the refrigerator 2, and the carbonization assembly 23 is configured to communicate with the refrigeration assembly 22. Part of the cold water flowing out of the refrigeration assembly 22 is configured to flow to the carbonization assembly 23 and generate bubble water. The water outlet pipeline is constructed to be connected to the liquid inlet pipeline, the refrigeration assembly 22, and the carbonization assembly 23, respectively, so as to discharge normal temperature water, cold water, and bubble water respectively through the water outlet pipeline. The specific structure of the refrigerator 2 provided in this embodiment refers to the above three embodiments and will not be repeated here.

[0133] Example 5

[0134] This embodiment provides a water supply system, including a water purifier 1, a refrigerator 2, and a connecting pipe 41. The water purifier 1 includes a first housing 18, within which a filter assembly 12 and a heating assembly 13 are disposed. The filter assembly 12 is configured to filter an external water source and to discharge filtered water at room temperature. The heating assembly 13 is configured to heat the filtered water at room temperature into hot water. The refrigerator 2 includes a second housing 27, within which a refrigeration assembly 22 is disposed. The refrigeration assembly 22 is configured to be separated from the heating assembly 13, and at least a portion of the filtered water at room temperature is configured to flow into the refrigeration assembly 22 for cooling and generating cold water. The connecting pipe 41 is disposed outside the first housing 18 and the second housing 27, and is configured to connect the water purifier 1 and the refrigerator 2, so as to deliver at least a portion of the filtered water at room temperature to the refrigeration assembly 22.

[0135] It should be noted that since the heating assembly 13 and the cooling assembly 22 are separately installed and do not affect each other, the connecting pipe 41 between the water purifier 1 and the chiller 2 can use a normal temperature water pipe, without the need for additional insulation. The connecting pipe 41 can transport the normal temperature water filtered by the water purifier 1 to the chiller 2 for cooling. The hot water heated by the heating assembly 13 can be directly discharged from the water purifier 1 for user use.

[0136] In one embodiment of the present application, the water supply system further includes a carbonation tank 231, which is configured to be disposed within the second housing 27, thereby serving as an internal component of the refrigerator 2. At least a portion of the cold water is configured to flow into the carbonation tank 231 and mix with carbon dioxide to produce sparkling water. By adding the carbonation tank 231, the refrigerator 2 not only produces cold water but also further processes the cold water into sparkling water, thereby enriching the taste and enhancing the user experience.

[0137] Furthermore, the refrigeration assembly 22 includes a cold water tank 221, which is used to cool the liquid. In one embodiment of the present application, the carbonation tank 231 is configured to be located within the cold water tank 221. Since the temperature within the cold water tank 221 is relatively low and continuously refrigerated, the carbonation tank 231 can be kept warm by the cold water tank 221, thereby improving the taste of the sparkling water provided by the water supply system.

[0138] In another embodiment of the present application, the carbonization tank 231 is constructed to be separated from the cold water tank 221. For example, the carbonization tank 231 can be set at a position inside the second shell 27 and outside the cold water tank 221; or the carbonization tank 231 can be independently set outside the second shell 27. In this case, the outlet of the cold water tank 221 is constructed to be connected to the carbonization tank 231 through a cold water pipe, and the cold water pipe is constructed as an insulated water pipe. The cold water tank 221 in this embodiment cannot provide insulation for the carbonization tank 231. In order to ensure that the water entering the carbonization tank 231 is cold water and does not overheat during transportation, the cold water pipe needs to be set as an insulated water pipe. An insulation structure can be added to the cold water pipe so that the cold water can maintain a low temperature when flowing through the cold water pipe.

[0139] Example 6

[0140] This embodiment provides a refrigerator 2, comprising a housing, within which are disposed: a liquid inlet pipeline, a refrigeration assembly 22, and a water outlet pipeline. The liquid inlet pipeline is configured to connect to a water purifier 1, and the refrigeration assembly 22 is configured to communicate with the liquid inlet pipeline. Normal-temperature water flowing out of the water purifier 1 is configured to flow through the liquid inlet pipeline into the refrigeration assembly 22 for cooling and generating cold water. The refrigeration assembly 22 includes a cold water tank 221, a compressor 222, a condenser 223, a fan 224, and an evaporator 225. The water outlet pipeline is configured to communicate with the refrigeration assembly 22 to discharge the cold water through the water outlet pipeline. The total weight of the refrigerator 2 is no less than 10 kg.

[0141] It is understandable that the cold water tank 221, compressor 222, condenser 223, fan 224, evaporator 225, and other components of the refrigeration assembly 22 are relatively heavy, resulting in a total weight of at least 10 kg for the refrigerator 2. If the refrigerator 2 and the water purifier 1 were to be integrated into one device, the resulting device would be too heavy, making it difficult to carry, install, and maintain.

[0142] In one embodiment of the present application, a carbonization tank 231 and a carbon dioxide gas source 232 are further provided in the housing; at least a portion of the cold water is configured to flow into the carbonization tank 231 and mix with the carbon dioxide to generate bubble water, and the total weight of the refrigerator 2 is not less than 14 kilograms. It is understandable that structures such as the carbonization tank 231 and the carbon dioxide gas source 232 have a large weight. When the refrigerator 2 is a bubble machine, the total weight of the refrigerator 2 is at least 14 kilograms. If the bubble machine and the water purifier 1 are to be integrated into one device, the integrated device will be too heavy and difficult to carry, install and maintain.

[0143] This application separates the water purifier 1 and the refrigerator 2 (bubble machine) provided in this embodiment into two devices, and integrates the functions of the two devices by connecting the two independent devices in series. The weight of a single device will not be too heavy, and it will be much easier to carry, install and maintain.

[0144] Example 7

[0145] This embodiment provides a water supply system, including a water purifier 1, a refrigerator 2 and a carbonization tank 231. The water purifier 1 includes a first shell 18, in which a filter assembly 12, a water inlet pump 17, a heat bladder 131 and a hot water pump 132 are arranged. The filter assembly 12 is configured to filter an external water source and to discharge filtered water at room temperature. The water inlet pump 17 is used to pump an external water source into the water purifier 1. Part of the filtered water can be pumped into the heat bladder 131 by the hot water pump 132, and heated in the heat bladder 131 to produce hot water, which can be stored in the heat bladder 131 for insulation.

[0146] The refrigerator 2 includes a second housing 27, within which a refrigeration assembly 22 is housed. At least a portion of the filtered ambient temperature water is configured to flow into the refrigeration assembly 22 for cooling and production of cold water. The refrigeration assembly 22 includes a cold water tank 221, a compressor 222, a condenser 223, a fan 224, and an evaporator 225. A carbonation tank 231 is configured to be housed within the second housing 27, serving as an internal component of the refrigerator 2. At least a portion of the cold water is configured to flow into the carbonation tank 231 and mix with carbon dioxide to produce sparkling water. The total weight of the water purifier 1, refrigerator 2, and carbonation tank 231 is no less than 28 kg.

[0147] Specifically, the total weight of the water purifier 1 is not less than 14 kilograms, and / or the total weight of the refrigerator 2 and the carbonization tank 231 is not less than 14 kilograms. It is understandable that the filter assembly 12, water inlet pump 17, heat tank 131, hot water pump 132 and other structures in the water purifier 1, the cold water tank 221, compressor 222, condenser 223, fan 224, evaporator 225 and other structures in the refrigeration assembly 22, and the carbonization tank 231 itself all have a large weight, which makes the total weight of the water purifier 1, refrigerator 2, and carbonization tank 231 at least 28 kilograms. If the water purifier 1, refrigerator 2, and carbonization tank 231 are integrated into one device, that is, if the functions of purifying water, discharging cold water, and discharging bubbling water are simultaneously realized through one device, the integrated device will be too heavy and difficult to carry, install, and maintain. This application separates the water purifier 1 and the refrigerator 2 (bubble machine) and integrates their functions in series. The weight of a single device will not be too heavy, and it will be much easier to carry, install and maintain.

[0148] Application Scenario 1

[0150] The user may have only reserved one socket 50 inside the cabinet. The first power port 114 on the water purifier 1 is connected to the socket 50 through the first power cord 51, and the socket 50 can supply power to the water purifier 1 through the first power cord 51.

[0156] The generated cold water is stored in the cold water tank 221. When the user needs to get cold water, just control the third control valve 203 to open, so that the cold water can flow out of the cold water tank 221 and flow to the water outlet 212 through the water outlet pipe, and then be transported to the liquid outlet device 3 through the liquid outlet pipe 43 for discharge.

[0157] Application Scenario 4

[0159] The generated bubble water can be stored in the carbonation tank 231. When the user needs to receive the bubble water, he only needs to control the fourth control valve 204 to open, so that the bubble water can flow out of the carbonation tank 231, flow to the water outlet 212 through the water outlet pipe, and be transported to the liquid outlet device 3 through the liquid outlet pipe 43 for discharge.
