Description

Technical Field

[0001] This utility model relates to the technical field of water dispensers, specifically an instant hot water dispenser. Background Technology

[0002] An instant hot water dispenser is a household or office appliance that can quickly heat and supply hot water, widely used in daily drinking scenarios such as making tea, coffee, and formula. Traditional instant hot water dispensers typically include basic components such as the main body, water tank, heating control module, and water outlet, using an electric heater to heat the water instantly.

[0003] The heating control module is usually fixedly installed inside the machine body, such as the instant hot water dispenser disclosed in Chinese Patent Publication No. CN222942169U. The heating component is installed in the lower space of the machine body, while the upper space is mainly used for installing pipes. This hinders the functional expansion of the instant hot water dispenser. Therefore, there is a need to design an instant hot water dispenser that can save installation space and can meet the functional needs in the future. Utility Model Content

[0004] The present invention aims to provide an instant hot water dispenser in which the heating control module is suspended in the upper part of the casing. This suspended design avoids the traditional installation method from occupying too much space in the lower part of the machine, thus freeing up the space in the lower part of the machine and realizing the effective use of space.

[0005] An instant hot water dispenser designed for this purpose includes a body, on which a water outlet assembly, a water storage tank, a shell, and a heating control module are provided; The water outlet assembly and the water storage tank form a separation area. The housing is installed on the separation area, and the heating control module is suspended on the housing. The lower part of the housing is provided with a functional expansion cavity for installing a second functional module.

[0006] The heating control module includes a bracket, a circuit board, an instant heater, and a water pump; The circuit board, instant heater, and water pump are all fixed on the bracket, and the circuit board is electrically connected to the instant heater and water pump respectively. When the water outlet assembly outputs hot water, the liquid in the water storage tank is pumped into the instant heater for heating.

[0007] The instantaneous heater and water pump are fixed at intervals on one side of the bracket, and the circuit board is fixed on the other side of the bracket.

[0008] The bracket has a first heat insulation plate and a second heat insulation plate on one side, and the instantaneous heater is installed between the first heat insulation plate and the second heat insulation plate.

[0009] The upper part of the housing is provided with a connecting column, and the bracket is provided with a connecting hole. When the heating control module is suspended and fixed on the housing, the connecting column and the connecting hole are correspondingly set and are fixedly engaged by fasteners.

[0010] The instantaneous heater is equipped with a temperature sensor for detecting the outlet water temperature.

[0011] The instantaneous heater is equipped with a dry-burning temperature controller.

[0012] The side of the housing is provided with heat dissipation holes.

[0013] The water storage tank is provided with a cavity for installing the filter module.

[0014] The top of the housing is provided with a positioning groove and a control circuit board module. A fixing member is provided on the positioning groove and the fixing member is installed in the positioning groove. The control circuit board module is installed in the lower part of the fixing member. A panel and a sealing member are provided on the upper part of the fixing member and the sealing member is disposed between the panel and the fixing member.

[0015] The heating control module of this invention is suspended in the upper part of the casing. This suspended design avoids the excessive space occupied by traditional installation methods in the lower part of the machine, freeing up space and achieving efficient space utilization. Previous instant water dispensers were limited by space constraints, making it difficult to expand their functions. However, because the heating control module is suspended, a functional expansion cavity is reserved in the lower part of the machine for installing a second functional module. Manufacturers can install corresponding second functional modules according to user needs, such as a chilled water tank with semiconductor cooling. Attached Figure Description

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-5 An instant hot water dispenser includes a body, on which a water outlet assembly 1, a water storage tank 2, a shell 3, and a heating control module 4 are provided; The water outlet assembly 1 and the water storage tank 2 form a separation area. The housing 3 is installed on the separation area. The heating control module 4 is suspended on the housing 3. The lower part of the housing 3 is provided with a functional expansion cavity 301 for installing the second functional module.

[0024] The heating control module 4 is suspended on the housing 3. This suspended design avoids the excessive space occupied by traditional installation methods in the lower part of the machine, freeing up space and achieving efficient space utilization. Previously, instant water dispensers were limited by space constraints, making it difficult to expand their functions. However, because the heating control module 4 is suspended, a functional expansion cavity 301 is reserved in the lower part of the machine for installing a second functional module. Manufacturers can install corresponding second functional modules according to user needs, such as a cooling water tank with semiconductor refrigeration, allowing the instant water dispenser to output cold water, enabling users to prepare cold drinks.

[0025] The heating control module 4 includes a bracket 401, a circuit board 402, an instant heater 403, and a water pump 404. The circuit board 402, the instant heater 403 and the water pump 404 are all fixed on the bracket 401, and the circuit board 402 is electrically connected to the instant heater 403 and the water pump 404 respectively. When the water outlet assembly 1 outputs hot water, the liquid in the water storage tank 2 enters the instant heater 403 via the water pump 404 for heating.

[0026] The water pump 404, circuit board 402, and instant heater 40 are integrated and fixed on the bracket 401. During installation, it is easy to fix the entire bracket 401 in the machine body. If a failure occurs later, it is also easy to disassemble and maintain the entire heating control module 4, and then replace it with a new heating control module 4. The old heating control module 4 can be returned to the original factory for inspection and maintenance.

[0027] The instantaneous heater 403 and water pump 404 are fixedly spaced on one side of the bracket 401, and the circuit board 402 is fixed on the other side of the bracket 401, effectively preventing the heat generated by the instantaneous heater 403 from being transferred to the water pump 404 and the circuit board 402. The instantaneous heater 403 generates a large amount of heat during operation. If it is too close to the circuit board 402, the heat can easily be conducted to the circuit board 402, affecting its normal operation. This spaced arrangement effectively increases the distance between them, reducing heat transfer; therefore, the bracket 401 has a certain thickness.

[0028] If the second functional module is a semiconductor refrigeration cooling water tank, the connection and disconnection of the water circuit between the water pump 404 and the cooling water tank are controlled by a solenoid valve and a three-way valve.

[0029] The first heat insulation plate 406 and the second heat insulation plate 407 act like two sturdy "heat insulation lines," effectively preventing some of the heat generated by the instantaneous heater 403 from dissipating outwards.

[0030] The bracket 401 has a first heat insulation plate 406 and a second heat insulation plate 407 on one side, and the instantaneous heater 403 is installed between the first heat insulation plate 406 and the second heat insulation plate 407. The upper part of the housing 3 is provided with a connecting post 302, and the bracket 401 is provided with a connecting hole 405. When the heating control module 4 is suspended and fixed on the housing 3, the connecting post 302 and the connecting hole 405 are correspondingly arranged, and the two are fixedly engaged by fasteners.

[0031] The fastener is a screw.

[0032] The instantaneous heater 403 is equipped with a temperature sensor 5 for detecting the outlet water temperature.

[0033] The instantaneous heater 403 is equipped with an anti-dry-burning thermostat 6.

[0034] The housing 3 has a heat dissipation hole 303 on its side, which connects the inside of the housing 3 with the outside air, which is conducive to heat dissipation of electrical components inside the housing 3.

[0035] The water storage tank 2 is provided with a cavity 201 for installing the filter module.

[0036] After the filter module is installed in the cavity 201, it has the effect of filtering liquid. The activated carbon filter in the filter module can effectively adsorb odors, residual chlorine and some organic matter in the water, improving the taste of the water; the PP cotton filter can intercept larger particles of mud, rust and other impurities in the water, preventing them from entering the subsequent heating and water supply systems.

[0037] The top of the housing 3 is provided with a positioning groove 304 and a control circuit board module 7. The positioning groove 304 is provided with a fixing member 8, which is installed in the positioning groove 304. The control circuit board module 7 is installed in the lower part of the fixing member 8. The upper part of the fixing member 8 is provided with a panel 10 and a sealing member 9. The sealing member 9 is located between the panel 10 and the fixing member 8 to prevent moisture from entering between the fixing member 8 and the panel 10.

[0038] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
