Description

Technical Field

[0001] This invention relates to the technical field of household appliances, and in particular to an instant-heating tea table. Background Technology

[0002] Chinese Patent No. 202222336552.2 discloses a tea bar machine, including a shell, a tea utensil processing unit and a water adding and boiling unit. The tea utensil processing unit includes a water storage box, a draining and storage rack, a cleaning mechanism, a disinfection mechanism and a ventilation and drying mechanism.

[0003] The drying mechanism of this tea bar machine includes a heating wire, which is installed in the fan hole. When energized, the heating wire heats the fluid passing through the fan hole.

[0004] The drying mechanism of this tea bar machine also includes a spray arm, and a steam generator is installed at the bottom of the spray arm. The high-temperature water vapor generated by the steam generator is sprayed into the cleaning chamber through the spray arm's spray holes.

[0005] The hot water in the cleaning mechanism is heated by another heating pipe and then sprayed into the cleaning chamber through the spray arm. Therefore, the cleaning mechanism and the drying mechanism are each equipped with a heating element, resulting in high product cost and large size.

[0006] In addition, existing teaware cleaning baskets are all welded together from several metal strips, resulting in long processing cycles and a less-than-simple product structure. Summary of the Invention

[0007] The purpose of this invention is to provide an instant hot water tea table. The hot water outlet system, heating and cleaning system, and drying and disinfection system of the instant hot water tea table are each connected to an instant hot water heater through pipes, so that the hot water outlet system, heating and cleaning system, and drying and disinfection system share a single instant hot water heater. This eliminates the need for separate heating components for each of the existing hot water outlet system, heating and cleaning system, and drying and disinfection system, and solves the technical problems of high product cost and large size.

[0008] An instant-heating tea table designed for this purpose includes a base with a water tap and a cleaning chamber for placing tea utensils. A hot water outlet system is provided on the base corresponding to the water tap. A heating and cleaning system and a drying and disinfection system for cleaning tea utensils are provided on the base corresponding to the cleaning chamber. An instant-heating heater for heating liquids is also provided on the base corresponding to the hot water outlet system, the heating and cleaning system, and the drying and disinfection system. The hot water outlet system, the heating and cleaning system, and the drying and disinfection system are each connected to the instant-heating heater through pipes, so that the hot water outlet system, the heating and cleaning system, and the drying and disinfection system share a single instant-heating heater. This eliminates the need for separate heating elements for each of the existing technologies, solving the technical problems of high product cost and large size.

[0009] The base is equipped with an inlet pump, a flow meter, and a solenoid valve. The inlet pump is connected to a water supply device. The inlet pump, flow meter, instant heater, solenoid valve, and faucet are connected in sequence to form a hot water outlet system. The flow meter detects the liquid flow rate entering the instant heater. With the teapot placed on the base, the hot water outlet system can achieve intelligent water dispensing. By setting the first liquid inlet volume to enter the instant heater in the control program of the instant tea table, when the flow meter detects that the liquid inlet volume has reached the first liquid inlet volume setting value, the inlet pump stops working and stops supplying water to the instant heater.

[0010] The base is equipped with an inlet pump, flow meter, solenoid valve, and cleaning pump. The inlet pump, flow meter, instant heater, solenoid valve, cleaning pump, and water inlet level of the cleaning chamber are connected in sequence to form a heating and cleaning system. By setting the second liquid inlet volume to enter the heater in the control program of the instant tea table, when the flow meter detects that the liquid inlet volume has reached the second liquid inlet volume set value, the water supply pump can stop working, the instant tea table will no longer receive water, and the cleaning pump will continue to work, continuing to supply water pressure to the water inlet level of the cleaning chamber, avoiding the water level in the cleaning chamber from being too high, and also achieving the effect of saving water.

[0011] The cleaning chamber is equipped with a rotating spray arm at the water inlet. The spray arm has several spray holes, and the hot water from the heating cleaning system is sprayed onto the teaware in the cleaning chamber through the spray holes.

[0012] The base is also equipped with a drain valve, and the cleaning chamber is equipped with a drain position. The drain position, drain valve, and cleaning pump are connected by pipes. When the drain valve is closed, the cleaning pump, spray arm, and drain position form a hot water circulation cleaning pipe. When the drain valve is open, the sewage in the cleaning chamber is discharged out of the cleaning chamber through the drain position and drain valve.

[0013] When the drain valve is closed, the cleaning pump, spray arm, and drain position form a hot water circulation cleaning pipe. Therefore, when the water supply pump can stop working, the instant heater of the instant tea table will no longer heat water (the water inlet pump and instant heater stop working). The cleaning pump will draw hot water from the circulation cleaning pipe to circulate and clean the teaware in the cleaning chamber, avoiding excessive water level in the cleaning chamber and also saving water.

[0014] Once cleaning is complete, the cleaning pump stops working, the drain valve opens, and the sewage flows to the drain position and drain valve. Then, the sewage flows along the pipe where the drain valve is located to the user's drain pipe.

[0015] A filter screen is installed at the drain position to prevent debris from flowing into the user's drain pipe and causing blockage.

[0016] The base is also equipped with an air blowing device. The air blowing device, instant heater, solenoid valve, cleaning pump, spray arm, and drain position are connected in sequence to form a drying and disinfection system. The hot air of the drying and disinfection system is sprayed onto the teaware in the cleaning chamber through the spray hole of the spray arm and / or the drain position.

[0017] The air blowing device includes an air pump or a blower, preferably an air pump, eliminating the need for a blower's air guide cover, thereby saving installation space for the component.

[0018] The instant heater's outer casing is equipped with a temperature sensor for detecting temperature. The main control chip on the tea table's controller inputs the control program via a computer. This program includes a drying control program, which corresponds to the drying and sterilization system and includes drying temperature, stop heating temperature, and drying time. The drying temperature can range from 70 to 120 degrees Celsius. When the drying control program is executed, the instant heater stops taking in water, and the cleaning pump stops working. Due to the upper limit of the drying temperature setting, the instant heater can continue to operate even in dry-burning conditions under the drying control program, achieving high-temperature sterilization and drying of the teaware at 120 degrees Celsius.

[0019] Under the drying control program, if the heating temperature of the instant heater continues to rise and exceeds the drying temperature, the instant heater will stop heating, and the blowing device can continue to work, blowing the residual heat of the instant heater into the teaware in the cavity until the drying process is completed. During this drying process, if the temperature of the instant heater gradually decreases and reaches the stop heating temperature, specifically, when the difference between the stop heating temperature and the drying temperature is 20-30 degrees Celsius, the control program will issue a signal to restart the instant heater, and the instant heater will begin heating.

[0020] In addition, the main control chip's control program also includes a heating and cleaning control program. The liquid will enter the instant heater through the water supply device for heating. The heating and cleaning control program has an anti-dry-burning temperature value, which can be set to be greater than 100 degrees Celsius, specifically 105 degrees Celsius to 120 degrees Celsius.

[0021] The spray arms have several spray holes arranged linearly, and some spray holes are staggered on the spray arms, or several spray holes are on the same line.

[0022] Several spray holes are staggered on the spray arm, allowing liquid to be sprayed from multiple directions, thus cleaning the teaware from multiple angles.

[0023] The instantaneous heater is equipped with a liquid heating channel, a heating element, a first temperature sensor for detecting the liquid heating temperature, and a second temperature sensor for detecting the temperature of its outer casing.

[0024] The base is equipped with a cover that covers the water inlet pump, flow meter, and solenoid valve.

[0025] The present invention has the following beneficial effects:

[0026] The hot water outlet system, heating and cleaning system, and drying and disinfection system are each connected to an instantaneous heater through pipes, so that the hot water outlet system, heating and cleaning system, and drying and disinfection system share a single instantaneous heater. This eliminates the need for existing technologies to equip each of the hot water outlet system, heating and cleaning system, and drying and disinfection system with a separate heating element, thus solving the technical problems of high product cost and large size.

[0027] When the drain valve is closed, the cleaning pump, spray arm, and drain position form a hot water circulation cleaning pipe. When the water supply pump can stop working, the instant heater of the instant tea table no longer heats water (the water inlet pump and instant heater stop working). The cleaning pump will draw hot water from the circulation cleaning pipe to circulate and clean the teaware in the cleaning chamber. The cleaning pump supplies water from the circulation cleaning pipe to the spray arm. The water sprayed from the spray arm flows to the drain position. The water in the drain position stays in the circulation cleaning pipe under the action of the drain valve being closed. The cleaning pump draws hot water from the circulation cleaning pipe to supply the spray arm, which avoids the water level in the cleaning chamber from being too high and also saves water.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] See Figures 1-8 An instant-heating tea table includes a base 1, which is provided with a water tap 2 and a cleaning chamber 6 for placing tea utensils 5. A hot water outlet system is provided on the base 1 corresponding to the water tap 2. A heating and cleaning system and a drying and disinfection system for cleaning tea utensils 5 are provided on the base 1 corresponding to the cleaning chamber 6. An instant-heating heater 4 for heating liquids is also provided on the base 1 corresponding to the hot water outlet system, the heating and cleaning system and the drying and disinfection system. The hot water outlet system, the heating and cleaning system and the drying and disinfection system are respectively connected to the instant-heating heater 4 through pipes so that the hot water outlet system, the heating and cleaning system and the drying and disinfection system share a single instant-heating heater 4.

[0038] See Figure 2 The base 1 is equipped with an inlet pump 3, a flow meter 7, and a solenoid valve 8. The inlet pump 3 is connected to a water supply device. The inlet pump 3, the flow meter 7, the instant heater 4, the solenoid valve 8, and the water faucet 2 are connected in sequence to form a hot water outlet system.

[0039] In this embodiment, the water pump 3, flow meter 7, instant heater 4, and solenoid valve 8 are all installed on the bottom of the base 1. The water pump 3, flow meter 7, instant heater 4, and solenoid valve 8 are fixed to the bottom of the base 1 by brackets, screws, etc. The water supply device includes a water inlet component installed on the bottom of the base 1. One end of the water inlet component is connected to the water pump 3, and the other end of the water inlet component is connected to the user's tap water pipe, or the other end of the water inlet component is inserted into a bottled water bottle.

[0040] In this embodiment, the liquid enters the instant heater 4 through the inlet pump 3 and flow meter 7 for heating, and the heated liquid flows to the outlet tap 2 through the solenoid valve 8.

[0041] See Figure 3 The base 1 is equipped with an inlet pump 3, a flow meter 7, a solenoid valve 8, and a cleaning pump 9; the inlet pump 3, the flow meter 7, the instant heater 4, the solenoid valve 8, the cleaning pump 9, and the water inlet of the cleaning chamber 6 are connected in sequence to form a heating and cleaning system.

[0042] In this embodiment, the solenoid valve 8 has two water outlets. One water outlet is connected to the cleaning pump, and the other water outlet is connected to the water tap 2 and the cleaning pump 9 used in the drying and disinfection system through the pipeline distribution valve.

[0043] When the liquid enters the instant heater 4 through the inlet pump 3 and the flow meter 7 for heating, and the cleaning pump 9 is working, the heated liquid flows to the cleaning pump 9 through the solenoid valve 8.

[0044] The cleaning chamber 6 is equipped with a rotating spray arm 12 at the water inlet. The spray arm 12 has several spray holes. Hot water from the heating cleaning system is sprayed onto the teaware 5 in the cleaning chamber 6 through the spray holes.

[0045] The cleaning pump 9 supplies water pressure to the spray arm 12, and the heated liquid is sprayed out through the spray arm 12.

[0046] The base 1 is also equipped with a drain valve 10, and the cleaning chamber 6 is equipped with a drain position 13. The drain position 13, the drain valve 10, and the cleaning pump 9 are connected by a pipe. When the drain valve 10 is closed, the cleaning pump 9, the spray arm 12, and the drain position 13 form a hot water circulation cleaning pipe. When the drain valve 10 is open, the sewage in the cleaning chamber 6 is discharged out of the cleaning chamber 6 through the drain position 13 and the drain valve 10.

[0047] A filter screen 14 is installed on the drain position 13.

[0048] See Figure 4 The base 1 is also equipped with an air blowing device 11. The air blowing device 11, the instant heater 4, the solenoid valve 8, the cleaning pump 9, the spray arm 12, and the drain position 13 are connected in sequence to form a drying and disinfection system. The hot air of the drying and disinfection system is sprayed onto the teaware 5 in the cleaning chamber 6 through the spray hole of the spray arm 12 and / or the drain position 13.

[0049] In this embodiment, the air blowing device 11 blows gas into the instant heater 4 for heating. The heated hot air is then blown towards the solenoid valve 8 and the cleaning pump 9 by the air blowing device 11. Finally, the hot air is sprayed onto the teaware 5 in the cleaning chamber 6 through the spray hole of the spray arm 12 and / or the drain position 13 to dry and / or disinfect the teaware 5 in the cleaning chamber 6.

[0050] Alternatively, hot air can be blown through solenoid valve 8 onto the pipe connecting solenoid valve 8 and faucet 2 to disinfect the hot water outlet system pipes.

[0051] The instantaneous heater 4 is equipped with a liquid heating channel, a heating element, a first temperature sensor for detecting the liquid heating temperature, and a second temperature sensor for detecting the temperature of its outer shell.

[0052] In this embodiment, the instantaneous heater 4 is provided with a liquid inlet 4.1 and an air inlet 4.2 that connect to the liquid heating channel. The liquid inlet 4.1 extends from one side of the air inlet 4.2. The instantaneous heater 4 is also provided with a water outlet 4.3 that connects to the liquid heating channel. The liquid inlet 4.1 of the instantaneous heater 4 is connected to the water outlet of the flow meter 7, the air inlet 4.2 of the instantaneous heater 4 is connected to the air blowing device 11, and the water outlet 4.3 of the instantaneous heater 4 is connected to the water inlet of the solenoid valve 8.

[0053] The spray arms 12 have several spray holes arranged in a linear manner, and some spray holes are staggered on the spray arms 12, or several spray holes are on the same line.

[0054] The temperature probe of the first temperature sensor extends into the liquid heating channel.

[0055] The base 1 is equipped with a cover 15 that covers the water inlet pump 3, flow meter 7, and solenoid valve 8.

[0056] In this embodiment, the base 1 and the cover 15 are fixedly connected by screws. The cover 15 has an inner cavity, and the top of the inner cavity has a flange that connects to the base 1.

[0057] The aforementioned electronic control components are electrically connected to the controller of the tea table via wires.

[0058] Specifically: The tea table also includes a controller. The controller's main control chip MCU inputs the control program through a computer. The control program includes a hot water outlet control program, a heating and cleaning control program, and a drying and disinfection control program. The hot water outlet control program corresponds to the flow meter 7, which has a first liquid inlet volume. The hot water outlet control program corresponds to the instant heater 4, which has a first hot water temperature value and a first anti-dry burning temperature value. When the flow meter 7 detects that the inlet volume of water entering the instant heater 4 reaches the first liquid inlet volume setting value, the water pump 3 stops working and stops supplying water to the instant heater 4. If the first temperature sensor detects that the liquid in the instant heater 4 reaches the first hot water temperature value (100 degrees Celsius), the solenoid valve 8 opens and water flows out of the faucet 2.

[0059] If the second temperature sensor detects that the outer shell temperature of the instant heater 4 reaches the anti-dry-burning temperature value, the controller controls the instant heater 4 to stop working; or, the controller controls the water pump 3 to work, and the water pump 3 pumps water into the instant heater 4 to cool the instant heater 4.

[0060] The heating and cleaning control program is configured with a second hot water temperature value and a first anti-dry-burning temperature value for the instant heater 4, and a second liquid inlet flow rate for the flow meter 7. When the heating and cleaning control program is executed, when the flow meter 7 detects that the inlet flow rate of the instant heater 4 reaches the second liquid inlet flow rate setting value, the inlet pump 3 stops working and stops supplying water to the instant heater 4. When the first temperature sensor detects that the liquid in the instant heater 4 reaches the second hot water temperature value, the cleaning pump 9 starts working and supplies the hot water from the instant heater 4 to the spray arm 12 of the cleaning chamber 6. The hot water is sprayed out of the spray hole of the spray arm 12 under water pressure.

[0061] The heating and cleaning control program has a heating and cleaning timer set for the drain valve 10. If the timer of the heating and cleaning control program does not reach the set heating and cleaning time, the drain valve 10 is closed. The cleaning pump 9, the spray arm 12, and the drain position 13 form a hot water circulation cleaning pipe. The water sprayed from the spray arm 12 flows to the drain position 13. The water in the drain position 13 remains in the circulation cleaning pipe under the action of the drain valve 10 being closed. The cleaning pump 13 draws hot water from the circulation cleaning pipe to supply the spray arm 12. This avoids the water level in the cleaning chamber from being too high and also saves water.

[0062] Once cleaning is complete, the cleaning pump 9 stops working, the drain valve 10 opens, and the sewage flows to the drain position 13 and the drain valve 10. Then, the sewage flows along the pipe where the drain valve 10 is located to the user's drain pipe.

[0063] The drying and disinfection control program is equipped with drying temperature value, third anti-dry burning temperature value, stop heating temperature value, drying time, etc. for the instant heater 4. The drying temperature value can be from 70 degrees Celsius to 120 degrees Celsius. When the drying control program is executed, the instant heater 4 no longer takes in water, and the water pump 3 and cleaning pump 9 stop working respectively. Due to the upper limit of the drying temperature value, the instant heater 4 can continue to work even in the case of dry burning under the drying control program, and achieve high-temperature disinfection and drying of teaware at 120 degrees Celsius.

[0064] Under the drying control program, if the heating temperature of the instant heater 4 continues to rise and the heating temperature of the instant heater 4 exceeds the drying temperature (the outer shell temperature of the instant heater 4 exceeds the drying temperature), the instant heater 4 stops heating, and the blowing device 11 can continue to work, blowing the residual heat of the instant heater 4 into the teaware 5 in the cleaning chamber 6 until the drying work is completed. During this drying process, if the temperature of the instant heater 4 gradually decreases and reaches the stop heating temperature (the outer shell temperature of the instant heater 4 is equal to or less than the stop heating temperature), specifically, when the difference between the stop heating temperature and the drying temperature is 20-30 degrees Celsius, the control program will issue a signal to restart the instant heater 4, and the instant heater 4 will start heating.

[0065] The tea table also features a touch-sensitive control panel on its controller that allows users to change the hot water output control program, heating and cleaning control program, drying and disinfection control program, as well as the water inflow and hot water temperature.

[0066] In this embodiment, the instantaneous heater 4, spray arm 12, etc. are common knowledge to those skilled in the art. The detailed internal structure of the instantaneous heater 4, spray arm 12, etc. will not be described in detail in this embodiment.

[0067] The above describes the preferred embodiments of the present invention, illustrating and describing the basic principles, main features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
