Description

Technical Field

[0001] The utility model relates to the field of hot water equipment, and particularly to an open type water heater. Background Art

[0002] At present, the water heaters on the market generally adopt an integrated inner tank design, which shows advantages in ensuring the structural stability and improving the heat energy transmission efficiency. However, after long-term use of the inner tank, it is easy to accumulate scale, impurities, etc. If not cleaned in time and effectively, it may not only affect the water quality and health, but also reduce the heating efficiency and even shorten the service life of the water heater. Moreover, the integrated inner tank structure of the water heater brings maintenance difficulties: since the inner tank is not detachable or difficult to open, users usually have many inconveniences when performing regular cleaning and maintenance of the inner tank. For example, the cleaning is mainly carried out by reverse flushing of water flow, and it is difficult to perform deep cleaning operations such as scrubbing and wiping inside the inner tank, unless a special cleaning device is used. Thus, there are problems of inconvenient and unclean cleaning, which affect the user experience and the overall performance of the product.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] The inner tank of the existing water heater is usually an integral structure. Although this design can ensure the structural stability and improve the heating efficiency, since it cannot be opened, the regular cleaning operation required for the inner tank is not convenient enough.

[0031] To solve the above technical problems, this embodiment provides an open-type water heater. Please refer to Figures 1 to 5 as shown, Figure 1 is a perspective view of the open-type water heater in the embodiment, Figure 2 is a top view of the open-type water heater in the embodiment, Figure 3 is a side view of the open-type water heater in the embodiment, Figure 4 is a schematic diagram of the open-type water heater in the first position in the embodiment, Figure 5 is a schematic diagram of the open-type water heater in the second position in the embodiment.

[0032] An open-type water heater in this embodiment includes: a shell 1 and a heating tank 2.

[0033] The housing 1 includes a housing main body 11 and a cover body 12. The housing main body 11 is provided with an inner cavity 101 for accommodating the heating tank 2 and other components. The cover body 12 is used to seal the inner cavity 101 and is detachably connected to the housing main body 11. It can be understood that sealing the inner cavity 101 means forming a relatively independent space for the inner cavity 101 to protect components such as the heating tank 2.

[0034] The heating tank 2 includes an inner tank 21 and an end cap 22. The inner tank 21 is fixedly arranged in the inner cavity 101 and has an opening 201 at one end facing the cover body 12. The end cap 22 is detachably connected to the inner tank 21 and is used to seal the opening 201. Among them, when the cover body 12 and the end cap 22 are opened, the interior of the inner tank 21 is exposed through the opening 201.

[0035] For the open-type water heater with the above technical solution, both the housing 1 and the heating tank 2 adopt a split structure, and each component is detachably connected. With such a setting, the housing 1 can open the inner cavity 101 of the housing main body 11 through the cover body 12 to expose the heating tank 2. At the same time, the heating tank 2 can open the opening 201 of the inner tank 21 through the end cap 22 to expose the interior of the inner tank 21, so as to facilitate the cleaning personnel to perform in-depth cleaning operations such as scrubbing and wiping on the interior of the inner tank 21, thereby improving the cleaning degree of the inner tank 21. It can be seen that the open-type water heater of the present utility model can improve the convenience and cleaning degree of cleaning the inner tank 21.

[0036] In one implementation manner of the detachable connection between the cover body 12 and the housing main body 11, the cover body 12 and the housing main body 11 are detachably connected through a snap structure 102. It can be understood that the snap structure 102 can be an existing snap structure 102.

[0037] Exemplarily, a groove is provided at the top of the housing main body 11, and the cover body 12 is fixed inside the groove through the snap structure 102 and can be opened by separating the snap.

[0038] Exemplarily, in another implementation manner of the detachable connection between the cover body 12 and the housing main body 11, the cover body 12 and the housing main body 11 are connected by screws.

[0039] In one embodiment of the above-mentioned end cover 22 being detachably connected to the inner liner 21 and sealing the opening 201, the shell body 11 is provided with an annular protrusion 103 on the periphery of the inner cavity 101, and an annular groove 104 is provided on the outside of the annular protrusion 103, and the annular groove 104 is arranged around the opening 201 of the inner liner 21; the inner liner 21 is integrally formed with an outer edge at the opening 201, and the outer edge is provided with a first groove 202 that is clamped on the outside of the annular protrusion 103, and a first clamping block 203 that is clamped on the inside of the annular groove 104; the end cover 22 is provided with a second groove 204 on the outer periphery that is clamped on the outside of the outer edge, and a second clamping block 205 that is clamped between the first clamping block 203 and the groove wall of the annular groove 104; wherein a sealing ring 24 is provided between the second groove 204 and the outer edge, and the end cover 22 and the inner liner 21 are detachably connected by bolts 23. With such arrangement, the inner liner 21, the end cover 22 and the shell body 11 cooperate with each other through the annular protrusion 103, the annular groove 104, the first groove 202, the first block 203, the second groove 204 and the second block 205, so as to achieve the purpose of rapid positioning and improve the connection strength. At the same time, the end cover 22 strengthens the sealing effect of the inner liner 21 through the sealing ring 24.

[0040] Illustratively, the second slot 204 is provided with an inwardly recessed arc groove on the slot wall of the second slot 204 , and the sealing ring 24 is fitted in the arc groove.

[0041] Exemplarily, the first clamping block 203 and the second clamping block 205 are tightly fitted with the inner side of the annular clamping groove 104 , thereby fixing the auxiliary end cover 22 relative to the inner container 21 in the vertical direction.

[0042] For example, another sealing ring is provided at the bottom of the annular groove 104 to further enhance the sealing performance. Furthermore, the horizontal cross-sections of the cover 12, the liner 21 and the end cap 22 are circular and are arranged coaxially.

[0043] In order to facilitate the output of hot water in the inner tank 21, a water outlet pipe 25 is provided on the end cover 22. One end of the water outlet pipe 25 is connected to the inner tank 21, and the other end passes through a preset hole on the cover body 12 and is used to output the hot water in the inner tank 21 to the outside.

[0044] Exemplarily, the water outlet pipe 25 is located at the center of the end cover 22 , and a water outlet valve is provided on the water outlet pipe 25 .

[0045] To facilitate the water flow into the inner tank 21, the open-type water heater includes a water inlet pipe 26, a Venturi tube 27, and a reflux pot 28 disposed in the inner cavity 101. The water inlet pipe 26 is used to input water flow into the inner tank 21, and the Venturi tube 27 and the reflux pot 28 are sequentially connected to the water inlet pipe 26. When the valve on the water inlet pipe 26 is opened and cold water flows into the inner tank 21 through the water inlet pipe 26, a negative pressure is generated first through the Venturi tube 27 on the reflux pot 28 to bring the air or water in the reflux pot 28 into the inner tank 21; when the water in the inner tank 21 is full, it flows out from the hot water outlet pipe 25; when the water outlet valve is closed after using the boiled water, the residual water in the outlet pipe 25 flows back to the heating tank 2 under the action of the Venturi tube 27, thus realizing the efficient transportation and use of the water flow.

[0046] The above-mentioned housing main body 11 can be an integral structure or a split structure. Exemplarily, the housing main body 11 includes a housing 1 upper part, a housing 1 middle part, and a housing 1 lower part that are fixedly connected in sequence from top to bottom, and the inner cavity 101 is provided in the housing 1 middle part. It can be understood that, like the existing water heaters, this open-type water heater also includes a heating device for heating the inner tank 21, such as a temperature regulator and a thermostat. This open-type water heater can also be provided with an electronic controller 3 for program control, an electronic temperature probe for sensing the water flow temperature in the inner tank 21, a power supply 4 for power supply, a dry-burning circuit breaker 5 for preventing the inner tank 21 from dry-burning and overheating, a reset device 6 for resetting the heating function, and other components to realize corresponding functions, which will not be elaborated here.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
