Description

Technical Field

[0001] The utility model relates to a kitchen appliance, in particular to a water purifier. Background Art

[0002] Pipeline machines are used in homes, offices, and schools to provide drinking water. Pipeline machines are usually used in conjunction with water purifiers. A water tank is usually set in the pipeline machine, and the water purified by the water purifier is stored in the water tank. According to the required drinking water temperature, the water in the water tank is directly supplied for drinking. Or the water stored in the water tank is heated by the heating device in the pipeline machine, so as to provide hot water that can be drunk directly. For example, the Chinese utility model patent "Water Storage Device and Drinking Water Purification Equipment" with the authorization announcement number CN211609274U (application number 202020021740.4) discloses a water tank in the drinking water purification equipment for storing water purified by the purifier. This structure is more suitable for environments where the drinking water purification equipment is frequently used, so as to ensure that the water in the water tank is frequently updated. For environments where the drinking water purification equipment is used less frequently, the water in the water tank is left standing for a long time, which is easy to breed bacteria and cannot meet the demand for fresh and clean water.

[0003] The kitchen instant hot water dispenser in CN217537177U does not need to be equipped with a water tank to store the water treated by the water purifier. Instead, by arranging the raw water pipeline and the clean water pipeline in the pipeline machine, the raw water can be directly transported to the water purifier through the raw water pipeline when the user receives water. The water purifier purifies the raw water in real time and outputs it to the clean water pipeline in the pipeline machine for use. When the kitchen instant hot water dispenser is used, fresh clean water is output in real time, avoiding the problem of bacteria breeding in the water when the use time interval is long, and ensuring the safety of water use at any time. However, this technical solution heats the clean water through the instant heating component, and the water temperature of the clean water before heating will change with the change of air temperature. Therefore, it is difficult to achieve that the instant heating component can heat the clean water to the target temperature at different initial temperatures. Utility Model Content

[0020] The utility model provides an instant heating control box for use with a water purifier. The instant heating control box and the water purifier are independent, so the water purifier can be equipped with a heating function by purchasing the instant heating control box separately, thus saving the user's cost.

[0033] refer to Figure 1-Figure 9 This embodiment provides a water purification component, including a water purifier 1, a water faucet 2 and an instant heating control box 3, wherein the water outlet channel of the water faucet 2 is connected to the water outlet end of the instant heating control box 3.

[0034] The instant heating control box 3 comprises: a box body 31, a suction assembly 32 placed in the box body 31, an instant heating assembly 33, a main control unit 34 and a temperature sensor 35; the suction assembly 32 comprises a first water pump 321 and a second water pump 322 with different flow rates; the water inlet ends of the first water pump 321 and the second water pump 322 are respectively used to connect to the purified water outlet end of the water purifier 1, and the water outlet ends of the first water pump 321 and the second water pump 322 are connected to the instant heating assembly 33 through the temperature sensor 35, and the water outlet end of the instant heating assembly 33 is the purified water outlet end 36 of the instant heating control box 3 after heating; the temperature sensor 35 is used to detect the water temperature of the water flowing out of the suction assembly 32, and the signal output end of the temperature sensor 35 is connected to the signal input end of the main control unit 34; the signal output end of the main control unit 34 is connected to the first water pump 321 and the second water pump 322. In this embodiment, the first water pump 321 is a large flow pump, and the second water pump 322 is a small flow pump. In order to fix the first water pump 321 and the second water pump 322 in this embodiment, the suction assembly 32 also includes a base 323 and a pressure cover 324, and the pressure cover 324 and the base 323 are connected together to form a chamber for accommodating the first water pump 321 and the second water pump 322. In addition, the base 323 is provided with a water inlet and outlet, and the base 323 is connected to the water inlet end and the water outlet end of the first water pump 321 and the second water pump 322 respectively. In this embodiment, two water pumps are taken as an example, and more water pumps can also be set as needed in the actual design. In addition, the temperature sensor 35 in this embodiment is used to detect the temperature of the water flowing out of the suction assembly 32. As a simple replacement, the temperature sensor 35 can also be set at the front end of the suction assembly to detect the water temperature of the water flowing into the suction assembly 32.

[0035] To realize that the base 323 is connected to the water inlet and outlet of the first water pump 321 and the second water pump 322 respectively, in this embodiment, the base 323 includes a water inlet joint 3231, a water outlet joint 3232 and a connecting joint 3233 respectively connected to the first water pump 321 and the second water pump 322; wherein the connecting joint 3233 includes a water inlet channel 32331 and a water outlet channel 32332; the water inlet channel 32331 is connected to the water inlet joint 3231, and the water outlet channel 32332 is connected to the water outlet joint 3232. In this way, the purified water can flow into the first water pump 321 or the second water pump 322 through the water inlet joint 3231, and then flow into the instant heating component 33 through the water outlet joint 3232.

[0036] The instant heating control box 3 is provided with two water pumps with different flow rates and a temperature sensor 35. The water temperature can be detected by the temperature sensor 35, so that different water pumps can be selected according to the water temperature. If the water temperature is relatively high and not much different from the target temperature, a large flow pump can be selected at this time, which can achieve a large flow of water while meeting the heating temperature. If the water temperature is relatively low and is quite different from the target temperature, a small flow pump needs to be selected to give priority to meeting the requirement that the outlet water temperature can reach the set temperature. In this way, whether the inlet water temperature is high or low, the outlet water temperature can reach the temperature set by the user by selecting water pumps with different flow rates, and the water temperature is relatively accurate and reliable. In addition, the flow regulation interval of each pump is limited. Increasing the number of water pumps can also increase the range covered by the adjustment interval of the outlet water flow rate, thereby increasing the range of flow regulation.

[0037] In this embodiment, in order to protect the first water pump 321 and the second water pump 322, the water inlet ends of the first water pump 321 and the second water pump 322 are connected to the clean water outlet end of the water purifier 1 through a zero-pressure valve 37. The zero-pressure valve 37 can prevent the first water pump 321 and the second water pump 322 from being subjected to the effect of water pressure for a long time, thereby increasing the life of the water pump and reducing the possibility of water leakage in the water pump. At the same time, it can also ensure that when the water pump is not working, the water pressure downstream of the zero-pressure valve 37 maintains a state of 0 water pressure, which plays a role in stopping water. Once the first water pump 321 or the second water pump 322 starts working, negative pressure is generated downstream of the zero-pressure valve 37, and the zero-pressure valve 37 opens. Clean water can enter the first water pump 321 or the second water pump 322 normally through the zero-pressure valve 37.

[0038] Due to the above structure, all the purified water must flow through the instant heating component 33. However, in daily use, not all use scenarios require the purified water to be heated. Therefore, in order to meet the use scenarios where the purified water does not need to be heated, the present embodiment also includes a water flow distributor 38, and the water flow distributor 38 includes a first water inlet end, a second water inlet end, a first water outlet end, and a second water outlet end; the first water inlet end is used to connect the municipal tap water, and in this embodiment, the angle valve 4 is connected. The first water outlet end is used to connect the raw water inlet end of the water purifier 1, so that the water inlet of the water purifier 1 is completed. The second water inlet end is used to connect the purified water outlet end 11 of the water purifier 1, and the second water outlet end is connected to one end of the three-way valve 39. In this way, the purified water output by the water purifier 1 can enter the three-way valve 39 through the second water outlet end. Among the remaining two ends of the three-way valve 39, one end forms a purified water outlet end 30 that is not heated through the solenoid valve 301, and the other end is connected to the water inlet end of the first water pump 321 and the second water pump 322. Therefore, as long as the solenoid valve 301 is opened, the unheated purified water outlet 30 can be opened to meet the user's demand for unheated purified water. In this embodiment, the opening of the solenoid valve 301 is controlled by sending a sensing signal to the main control unit 34 using touch sensing at the water outlet faucet 2. The main control unit 34 controls the opening of the solenoid valve 301. As a simple replacement, infrared sensing or distance sensing can also be used. The water flow distributor 38 can also solve the problem of frequent startup of the water purifier due to the small hot water flow rate. When the hot water flow rate is small and less than the water inlet flow of the water purifier, the water of the water purifier can flow back from the water flow distributor 38 to the water inlet of the water purifier to avoid repeated startup of the water purifier.

[0039] Since the instant hot water control box 3 in this embodiment has an unheated purified water outlet 30 and a heated purified water outlet 36, there are two independent water paths in the water outlet faucet 2, which are respectively connected to the unheated purified water outlet 30 and the heated purified water outlet 36 through a hose 21. The water outlet faucet 2 is also connected to the main control unit 34 through a signal line 22, so that the user can send instructions to the main control unit 34 through the operation panel 23 on the water outlet faucet 2, select unheated purified water or heated purified water, and can also set the heating temperature of purified water.

[0040] Specifically, the operation panel 23 on the water faucet 2 has a water switch 231, a child lock 232, a temperature adjustment switch 233 and a quantitative switch 234. Touching the water switch 231 can output purified water at room temperature. Touching the child lock 232 to unlock and then touching the water switch 231 can output heated purified water. The display screen 235 on the water faucet 2 displays the current temperature and flow of the water. Touching the quantitative switch 234 can output a certain amount of water. Touching the thermostat 233 can output water at a temperature of 95C°, 75C°, 45C, etc.

[0041] In this embodiment, the instant heating component 33 includes a thick film heating body 331 and a thermostat 332, and the signal output end of the main control unit 34 is also connected to the thermostat 332. The thick film heating body 331 belongs to a mature instant heating method in the prior art, and this application does not improve it, so the thick film heating body 331 is not described in detail. The function of the thermostat 332 is to receive instructions from the main control unit 34, so as to set the target temperature of the rear film heating body 331.

[0042] Since the instant hot control box 3 is a separate component outside the water purifier 1, it is necessary to fix the instant hot control box 3. To this end, the present embodiment also includes a mounting piece for detachably fixing the box body 31 to a wall surface, which can be a cabinet body, a kitchen wall, or a housing of the water purifier 1.

[0043] There are many types of mounting parts that can be selected, such as adhesive tapes widely available in the prior art. The mounting parts selected in this embodiment include a connector 311 detachably arranged on the wall surface and a connecting fitting 312 arranged on the box body 31. Specifically, the connector is a dovetail convex strip 311, and the connecting fitting 312 is a dovetail groove. The connector 311 can be adhered to the outer shell of the water purifier 1 by adhesive, or it can be fixed to the cabinet body of the cabinet by bolts.

[0044] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
