Description

Technical Field

[0001] The invention relates to the field of water heaters, and in particular to a top-draw gas water heater. Background Art

[0002] Gas water heaters are a common household appliance widely used in household hot water supply. With the development of technology, the types and functions of gas water heaters are also increasing. Among them, top-draw gas water heaters are favored by the market due to their reasonable structural design. However, the existing top-draw gas water heaters face some problems that need to be solved in the development and production process.

[0003] Existing top-draw gas water heaters are mainly divided into two categories: zero cold water models and non-zero cold water models. Zero cold water models can quickly provide hot water through circulation heating technology, avoiding users from waiting for hot water for too long and improving the user experience. Non-zero cold water models are relatively simple and low in cost, but users need to wait for a while before getting hot water. These two models have their own advantages in the market and meet the needs of different users.

[0004] During the development process, developers usually need to develop both zero-cold-water models and non-zero-cold-water models to meet the needs of different users. However, there are differences in the specifications of the parts of the two models, which requires developers to prepare parts of two specifications, increasing development costs and management difficulties. Since the parts of the two models are not completely universal, developers need to purchase, store and manage the two specifications of parts separately during the production process, which not only increases costs but also reduces production efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a top-draw gas water heater to overcome the defects in the prior art that there are differences in the specifications of parts between zero-cold-water models and non-zero-cold-water models, which cannot be completely universal, increase development costs and management difficulties, increase costs, and reduce production efficiency.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A top-draw gas water heater, characterized in that it comprises:

[0008] A housing having a receiving cavity therein;

[0009] The right side of the bottom of the accommodating cavity is a pump accommodating portion, and the pump accommodating portion can be provided with a water pump assembly;

[0010] A first electric control component or a second electric control component can be arranged on the left side of the bottom of the accommodating cavity, wherein the first electric control component includes a water pump avoidance groove, and the second electric control component does not include a water pump avoidance groove;

[0011] A first heat exchange component or a second heat exchange component is arranged on the upper part of the accommodating chamber, and the first heat exchange component and the second heat exchange component both include a water outlet pipe, a heat exchanger and a water inlet pipe, wherein the water inlet pipe of the first heat exchange component is connected to the water pump component, and the water inlet pipe of the second heat exchange component is connected to the water inlet.

[0012] In the present solution, the above structure is adopted, and the present solution realizes the sharing of most of the components of the zero cold water model and the non-zero cold water model through optimized design. Except for the difference in the selection of the heat exchange component and the electronic control component and whether a water pump is provided, the other components are of the same specifications, and the sharing rate reaches more than 95%. Among them, the first heat exchange component and the second heat exchange component are respectively applied to the zero cold water water heater and the non-zero cold water water heater, which greatly reduces the development and production costs and improves the production efficiency. In addition, by respectively arranging the pump accommodation part and the electronic control component on the right and left sides of the bottom of the accommodation cavity, the present invention optimizes the spatial layout inside the water heater. This layout not only improves the integration, but also makes the size of the whole machine more compact. By optimizing the internal structure design, the gas water heater of the present invention achieves a significant reduction in volume while maintaining functional integrity, which is convenient for installation and use.

[0013] Preferably, the top-draw gas water heater also includes a proportional valve assembly, which is arranged on the bottom left side of the accommodating cavity. The proportional valve assembly includes a front tube assembly, which is arranged along the front-to-back direction of the accommodating cavity and / or the front tube assembly is an integrated core-pulling structure.

[0014] In this solution, the above structure is adopted, and the front pipe assembly adopts a side-mounted integrated core-pulling structure, which rationally utilizes the lower space of the movement, reduces the space for arranging the front pipe proportional valve, leaves space for the installation of other parts, and reduces the size of the whole machine. This design not only optimizes the internal space layout of the gas water heater and improves the space utilization rate, but also reduces the production cost and improves the production efficiency by reducing the number of parts and simplifying the assembly process. At the same time, the integrated core-pulling structure improves the stability and reliability of the front pipe assembly and enhances the overall performance of the product.

[0015] Preferably, the front pipe assembly may be segmented in a 2-4-6 or 1-3-4-6 manner.

[0016] In this solution, the above structure is adopted, and the front pipe assembly adopts a 2-4-6 or 1-3-4-6 segmentation method. Two different segmentation schemes can be achieved by simply adjusting the position of the round rod core pulling. This design not only improves the flexibility of production, but also reduces the complexity of the mold and the manufacturing cost. At the same time, this flexible segmentation method can meet the production requirements of gas water heaters of different models and functional requirements, further improving the versatility and adaptability of the product.

[0017] Preferably, the water pump assembly comprises a water pump and a direct-connection valve, and the water pump is connected to the water inlet pipe via the direct-connection valve.

[0018] In this solution, the above structure is adopted, and a direct-connection structure is adopted between the water pump and the water valve by selecting a plug-in valve, which saves intermediate connecting parts, avoids water leakage problems caused by multi-stage connections, and reduces costs and installation space.

[0019] Preferably, the water pump assembly also includes a water pump mounting plate, and the water pump is mounted on the bottom surface of the accommodating cavity through the water pump mounting plate. The water pump mounting plate is an integrated structure, and the water pump mounting plate is fitted with the bottom surface of the accommodating cavity through flanges on all sides.

[0020] In this solution, the above structure is adopted, and the integrated structure and flange increase the strength of the bracket and eliminate the gap between the bracket and the mounting surface, thereby increasing the installation strength of the water pump and avoiding noise caused by vibration of the water pump caused by installation.

[0021] Preferably, the first heat exchange component and the second heat exchange component are arranged in a manner that water flows in from bottom to top and out from top.

[0022] In this solution, the above structure is adopted, and the water flow is arranged in a bottom-in-top-out manner, which can ensure that the cold water is gradually heated from the bottom after entering the heat exchanger. As the water flow rises, the temperature gradually increases, and finally the hot water is discharged from the top outlet. This design allows the water flow to stay in the heat exchanger for a longer time, and the heat exchange is more sufficient, thereby improving the heat exchange efficiency. The problem of small load condensation water is solved to the greatest extent.

[0023] Preferably, the first heat exchange component and the second heat exchange component include a heat exchanger and a side reinforcement plate, the side reinforcement plate is arranged on the side of the heat exchanger, the side reinforcement plate is provided with a flange facing the heat exchanger, the width of the side reinforcement plate is greater than the width of the fin of the heat exchanger, and the water inlet pipe and the water outlet pipe extend from the side reinforcement plate.

[0024] In the present solution, the above structure is adopted, and the side reinforcing plates are used to protect the fins, especially in the case of bumps that may occur during transportation, at which time the fins can be effectively fixed and protected.

[0025] Preferably, the top-draw gas water heater also includes a fan assembly, which is arranged at the top of the accommodating cavity. The fan assembly includes a fan and an air collecting hood. The air collecting hood includes a fan mounting plate and a surrounding plate extending downward from the fan mounting plate. The fan is mounted on the fan mounting plate, and the air collecting hood is fixed to the combustion chamber through the surrounding plate.

[0026] In the present solution, the above-mentioned structure is adopted, and the fan mounting plate of the air collecting hood and the lower enclosure are combined into one plate, which can reduce the cost of the entire product. The enclosure of the air collecting hood is provided with mounting holes, which can be locked and fixed to the combustion chamber casing. This connection method can prevent the air collecting hood from being deformed and leaking due to collisions such as falling, thereby worsening the combustion effect.

[0027] Preferably, the top of one side of the first electronic control component close to the water pump is recessed inward to form the water pump avoidance groove, and the pump head of the water pump extends into the water pump avoidance groove.

[0028] In this solution, the above structure is adopted, and the design of the water pump avoidance groove allows the water pump to be arranged more compactly next to the first electric control component, reducing the space occupied between the water pump and the electric control component. This compact layout makes the internal space utilization of the entire gas water heater more reasonable, and further reduces the size of the whole machine.

[0029] Preferably, the first electronic control component and the second electronic control component have an electronic control housing, the electronic control housing is used to accommodate electronic control elements, the electronic control housing is fixed to the bottom plate of the accommodating cavity, and the electronic control housing has reinforcing ribs.

[0030] In this solution, the above structure is adopted, and the housing of the electric controller is enhanced in strength and stability of the overall structure by adding reinforcing ribs. The design of the reinforcing ribs can effectively prevent the housing from deforming during use, ensuring that the electric control components can operate stably under various working conditions. In addition, the fixing of the housing to the bottom plate of the accommodating cavity also enhances the overall structural stability.

[0031] The positive progressive effect of the present invention is that this scheme realizes the sharing of most of the components of the zero cold water model and the non-zero cold water model through optimized design. Except for the differences in the selection of heat exchange components and electronic control components and whether a water pump is provided, other components are of the same specifications, and the sharing rate reaches more than 95%. Among them, the first heat exchange component and the second heat exchange component are respectively applied to zero cold water water heaters and non-zero cold water water heaters, which greatly reduces the development and production costs and improves production efficiency. In addition, by respectively arranging the pump accommodation part and the electronic control component on the right and left sides of the bottom of the accommodation cavity, the present invention optimizes the spatial layout inside the water heater. This layout not only improves the integration, but also makes the size of the whole machine more compact. By optimizing the internal structure design, the gas water heater of the present invention achieves a significant reduction in volume while maintaining functional integrity, which is convenient for installation and use.

[0071] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0072] like Figure 1 As shown, this embodiment provides a top-draw gas water heater, which includes a shell 100, and the shell 100 has a housing 101. The right side of the bottom of the housing 101 is a pump housing 103, and the pump housing 103 can be provided with a water pump assembly 5. The left side of the bottom of the housing 101 can be provided with a first electric control assembly 11, and the first electric control assembly 11 includes a water pump avoidance groove 111. The upper part of the housing 101 is provided with a first heat exchange assembly 41, and the first heat exchange assembly 41 includes a water outlet pipe 402, a heat exchanger 43 and a water inlet pipe 401, wherein the water inlet pipe 401 of the first heat exchange assembly 41 is connected to the water pump assembly 5.

[0073] This embodiment is a zero cold water pump-type gas water heater, which only needs to install the first electric control component 11 and the first heat exchange component 41 inside, and install the water pump component 5 in the water pump accommodating portion 103, and the other parts are completely consistent with the non-zero cold water model. The first heat exchange component 41 and the second heat exchange component 42 are only slightly different in the bottom connection position of the water inlet pipe 401, because the two are connected to different objects, and the rest of the structure is completely consistent.

[0074] This solution achieves the sharing of most of the components of zero cold water models and non-zero cold water models through optimized design. Except for the differences in the selection of heat exchange components and electronic control components and whether a water pump is provided, other components are of the same specifications, and the sharing rate reaches more than 95%. Among them, the first heat exchange component 41 and the second heat exchange component 42 are respectively applied to zero cold water water heaters and non-zero cold water water heaters, which greatly reduces the development and production costs and improves production efficiency. In addition, by respectively arranging the pump accommodating portion 103 and the electronic control component on the right and left sides of the bottom of the accommodating cavity 101, the present invention optimizes the spatial layout inside the water heater. This layout not only improves the integration, but also makes the size of the whole machine more compact. By optimizing the internal structure design, the gas water heater of the present invention achieves a significant reduction in volume while maintaining functional integrity, which is convenient for installation and use.

[0075] like Figure 2 , 4 As shown, the top-draw gas water heater also includes a proportional valve assembly 3, which is arranged on the left side of the bottom of the accommodating chamber 101. The proportional valve assembly 3 includes a front pipe assembly 31, which is arranged along the front-to-back direction of the accommodating chamber and is an integrated core-pulling structure. The front pipe assembly 31 adopts a side-mounted integrated core-pulling structure, which makes rational use of the lower space of the movement, reduces the space for arranging the front pipe proportional valve, leaves space for the installation of other parts, and reduces the size of the whole machine. This design not only optimizes the internal space layout of the gas water heater and improves the space utilization rate, but also reduces the production cost and improves the production efficiency by reducing the number of parts and simplifying the assembly process. At the same time, the integrated core-pulling structure improves the stability and reliability of the front pipe assembly 31 and enhances the overall performance of the product. In other embodiments, it can also be only an integrated core-pulling structure or only a side-mounted structure.

[0076] like Figure 4 As shown, the segmentation of the front pipe assembly 31 can be 2-4-6 or 1-3-4-6. The front pipe assembly 31 adopts a segmentation of 2-4-6 or 1-3-4-6, and two different segmentation schemes can be achieved by simply adjusting the position of the round rod core pulling. This design not only improves the flexibility of production, but also reduces the complexity of the mold and the manufacturing cost. At the same time, this flexible segmentation method can meet the production requirements of gas water heaters of different models and functional requirements, further improving the versatility and adaptability of the product.

[0077] like Figure 6 As shown, the water pump assembly 5 includes a water pump 51 and a plug-in valve 53, and the water pump 51 is connected to the water inlet pipe 401 through the plug-in valve 53. By selecting the plug-in valve 53, a direct connection structure is adopted between the water pump 51 and the water valve, which saves intermediate connecting parts, avoids water leakage caused by multi-stage connection, and reduces costs and installation space.

[0078] like Figure 6 As shown, the water pump assembly 5 also includes a water pump mounting plate 52, through which the water pump 51 is mounted on the bottom surface of the accommodating cavity 101. The water pump mounting plate 52 is an integrated structure, and the water pump mounting plate 52 is attached to the bottom surface of the accommodating cavity 101 through flanges. The integrated structure and flanges increase the strength of the bracket and eliminate the gap between the bracket and the mounting surface, thereby increasing the installation strength of the water pump 51 and avoiding noise caused by vibration of the water pump 51 due to installation.

[0079] like Figure 3 As shown, the first heat exchange component 41 and the second heat exchange component 42 are arranged in a way that water flows in from the bottom and out from the top. The water flows in a way that water flows in from the bottom and out from the top, which can ensure that after the cold water enters the heat exchanger 43, it is gradually heated from the bottom, and as the water flows upward, the temperature gradually increases, and finally the hot water is discharged from the top outlet. This design allows the water flow to stay in the heat exchanger 43 for a longer time, and the heat exchange is more sufficient, thereby improving the heat exchange efficiency. The problem of small load condensation water is solved to the greatest extent.

[0080] like Figure 3 As shown, the first heat exchange assembly 41 and the second heat exchange assembly 42 include a heat exchanger 43 and a side reinforcing plate 44, the side reinforcing plate 44 is arranged on the side of the heat exchanger 43, the side reinforcing plate 44 is provided with a flange facing the heat exchanger 43, the width of the side reinforcing plate 44 is greater than the width of the fins of the heat exchanger 43, and the water inlet pipe 401 and the water outlet pipe 402 extend from the side reinforcing plate 44. The side reinforcing plate 44 is used to protect the fins, especially in the case of bumps that may occur during transportation, at this time, the fins can be effectively fixed and protected.

[0081] like Figure 5 As shown, the top-draw gas water heater also includes a fan assembly 6, which is arranged at the top of the accommodating chamber 101. The fan assembly 6 includes a fan 61 and an air collecting hood 62. The air collecting hood 62 includes a fan mounting piece 621 and a panel 622 extending downward from the fan mounting piece. The fan 61 is mounted on the fan mounting piece 621, and the air collecting hood 62 is fixed to the combustion chamber 2 through the panel 622. The fan mounting piece 621 of the air collecting hood 62 and the lower panel 622 are combined into one plate, which can reduce the cost of the entire product. The panel 622 of the air collecting hood 62 is provided with a mounting hole, which can be locked and fixed with the outer shell of the combustion chamber 2. This connection method can prevent the air collecting hood 62 from being deformed due to collisions such as falling, thereby leaking air, and thus making the combustion effect worse.

[0082] like Figure 7As shown, the top of one side of the first electric control component 11 near the water pump 51 is recessed inward to form a water pump avoidance groove 111, and the pump head of the water pump 51 extends into the water pump avoidance groove 111. The design of the water pump avoidance groove 111 allows the water pump 51 to be arranged more compactly next to the first electric control component 11, reducing the space occupied between the water pump 51 and the electric control component. This compact layout makes the internal space utilization of the entire gas water heater more reasonable and further reduces the size of the entire machine.

[0083] like Figure 7 As shown, the first electric control component 11 and the second electric control component 12 have an electric controller housing 112, the electric controller housing 112 is used to accommodate the electric control element, the electric controller housing 112 is fixed to the bottom plate of the accommodating cavity 101, and the electric controller housing 112 has a reinforcing rib 114. The electric controller housing 112 improves the strength and stability of the overall structure by adding the reinforcing rib 114. The design of the reinforcing rib 114 can effectively prevent the housing from being deformed during use, and ensure that the electric control element can operate stably under various working conditions. In addition, the fixing of the housing to the bottom plate of the accommodating cavity 101 also enhances the overall structural stability.

[0084] Example 2

[0085] like Figures 8 to 11 As shown, the top-draw gas water heater of this embodiment is a non-zero cold water gas water heater. Its general structure is basically the same as that of embodiment 1. The only difference is the selected heat exchange component and electric control component and the water pump is not installed.

[0086] like Figure 8 , Fig. 9 As shown, this embodiment provides a top-draw gas water heater, which includes a housing 100, and a housing 101 is provided in the housing 100. The right side of the bottom of the housing 101 is a pump housing 103, but the pump housing 103 is not provided with a water pump assembly 5. The left side of the bottom of the housing 101 can be provided with a second electric control assembly 12, and the second electric control assembly 12 is as shown in FIG. Fig.11 As shown, the second electric control component 12 is not provided with a water pump avoidance groove 111. A second heat exchange component 42 is provided at the upper portion of the accommodating chamber 101. Fig.10 As shown, the second heat exchange component 42 includes a water outlet pipe 402 , a heat exchanger 43 and a water inlet pipe 401 , wherein the water inlet pipe 401 of the second heat exchange component 42 is directly connected to the water inlet 102 .

[0087] Compared with Example 1, in Example 2, except for the difference in the selection of heat exchange components and electronic control components and whether a water pump is provided, other components are of the same specifications, and the commonality rate reaches more than 95%.
