Description

Technical Field

[0001] This utility model relates to the field of gas-fired wall-hung boiler technology, specifically to a condensate collection box for a wall-hung boiler and a gas-fired wall-hung boiler. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Existing wall-hung boiler condensate collection boxes typically have a condensate inlet and a rainwater inlet. The condensate inlet is connected to the condenser heat exchanger and is used to collect the condensate liquefied by the combustion heat exchange of the condenser. The bottom of the condensate inlet is usually designed with a water seal structure to prevent the exhaust gas generated by combustion from being emitted into the room. The rainwater inlet is used to connect to the rainwater collection tray so that the collected rainwater is collected through the condensate collection box and discharged from the machine through the drain outlet, thereby preventing rainwater from entering the machine and causing damage to its internal components.

[0004] Because the condensate collection box only has a water seal structure below the condensate inlet, while there is no water seal structure below the rainwater inlet, when the machine is running, due to the pressure difference between the inside and outside of the machine, outside air can be drawn into the machine through the condensate collection box to participate in combustion. Long-term operation will lead to a reduction in the amount of indoor air and a decrease in the oxygen content of the user's indoor space, which will affect the user's health. Utility Model Content

[0005] To overcome the defects described in the prior art, this utility model provides a condensate collection box for wall-hung boilers. By setting the condensate guide channel, rainwater guide channel, and water outlet channel all inside the collection chamber, and by having a height difference between the top of the water outlet channel and the bottom of both the condensate guide channel and the bottom of the rainwater guide channel, a double water seal structure can be formed. This solves the problem of indoor air flowing back into the machine to participate in combustion due to the pressure difference between the inside and outside of the machine, thereby avoiding the consumption of indoor air by the user and reducing safety hazards.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A condensate collection box for a wall-hung boiler includes a box body, wherein a collection chamber is formed inside the box body, wherein:

[0008] The box body is also provided with a condensate drainage channel, a rainwater drainage channel and a water outlet channel. The bottom of the condensate drainage channel is connected to the collection chamber, the bottom of the rainwater drainage channel is connected to the collection chamber, and the top of the water outlet channel is connected to the collection chamber.

[0009] There is a height difference between the top of the water outlet channel and the bottom of the condensate diversion channel, and between the top of the water outlet channel and the bottom of the rainwater diversion channel, to form a double water seal structure.

[0010] Furthermore, the box body is also equipped with a condensate collection interface, a rainwater collection interface, and a water outlet interface, wherein:

[0011] The condensate collection port is connected to the top of the condensate diversion channel, the rainwater collection port is connected to the top of the rainwater diversion channel, and the water outlet port is connected to the bottom of the water outlet channel.

[0012] Furthermore, the box body includes a first box body and a second box body connected vertically, wherein:

[0013] The first box has a first cavity with a bottom opening inside, and the second box has a second cavity with a top opening inside. When the first box and the second box are connected vertically, the first cavity and the second cavity communicate with each other and enclose each other to form the collection cavity.

[0014] The first box body has a condensate drainage channel and a rainwater drainage channel inside, and a condensate collection port and a rainwater collection port on the top of the first box body;

[0015] The second box has a water outlet channel inside and a water outlet interface at the bottom.

[0016] Furthermore, the interior of the first box is provided with a first column and a second column arranged at intervals. The interior of the first column has a through first groove to form the condensate drainage channel, and the interior of the second column has a through second groove to form the rainwater drainage channel.

[0017] Furthermore, both the first column and the second column are arranged to extend vertically in the up-down direction.

[0018] Furthermore, the interior of the second box is provided with a third column, and the interior of the third column is provided with a through third groove to form the water outlet channel.

[0021] Furthermore, the connector has an internal thread, and the outer peripheral wall of the first box or the second box has an external thread that matches the internal thread.

[0022] In addition, this utility model also provides a gas wall-hung boiler, including the aforementioned condensate collection box for the wall-hung boiler.

[0023] In summary, the condensate collection box and gas-fired wall-hung boiler provided by this utility model have the following beneficial effects:

[0024] (1) The condensate collection box for wall-mounted boilers of this utility model has a height difference between the top of the water outlet channel and the bottom of the condensate guide channel, and between the top of the water outlet channel and the bottom of the rainwater guide channel. This can form a double water seal structure, thereby solving the problem of indoor air flowing back into the machine to participate in combustion due to the pressure difference between the indoor and outdoor areas of the machine, thus avoiding the consumption of indoor air by users and reducing safety hazards.

[0025] (2) The condensate collection box for wall-mounted boilers of this utility model sets the condensate flow channel, rainwater flow channel and water outlet channel in the collection chamber.

Detailed Implementation

[0033] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] See Figure 1-4 This utility model provides a condensate collection box for a wall-hung boiler, including a box body with a collection cavity inside. The box body also includes a condensate guide channel, a rainwater guide channel, and a water outlet channel. The bottom of the condensate guide channel is connected to the collection cavity, the bottom of the rainwater guide channel is connected to the collection cavity, and the top of the water outlet channel is connected to the collection cavity.

[0037] Therefore, based on the above structure, the condensate produced after the condenser combustion heat exchange liquefaction can flow into the collection chamber through the condensate guide channel, and the rainwater collected by the rainwater receiving pan can flow into the collection chamber through the rainwater guide channel. When the water level in the collection chamber exceeds the top height of the outlet channel, the water in the collection chamber can be discharged to the outside of the machine through the outlet channel.

[0038] There is a height difference H between the top of the water outlet channel and the bottom of the condensate diversion channel, and between the top of the water outlet channel and the bottom of the rainwater diversion channel, to form a double water seal structure (e.g., Figure 4(As shown). Thus, when the water level in the collection chamber rises to a certain height, it can form a double water seal structure. The water seal structure located below the condensate drainage channel can prevent the exhaust gas generated by combustion from being emitted into the room, while the water seal structure located below the rainwater drainage channel can prevent indoor air from flowing back into the machine to participate in combustion due to the pressure difference between the inside and outside of the machine. This avoids consuming indoor air, reduces safety hazards, and ensures the health of users.

[0039] In addition, since the entire condensate collection box uses only one cavity design, the external size of the parts is greatly reduced, which facilitates its installation inside the machine and makes the overall size of the machine more compact.

[0040] See Figure 1-4 More specifically, the box body includes a first box body 1 and a second box body 2 connected vertically. Preferably, both the first box body 1 and the second box body 2 are cylindrical structures. The first box body 1 has a first cavity 11 with a bottom opening inside, and the second box body 2 has a second cavity 21 with a top opening inside. When the first box body 1 and the second box body 2 are nested together vertically, the first cavity 11 and the second cavity 21 are interconnected and enclose each other to form a collection cavity.

[0041] It should be noted that in this embodiment, since the diameter of the first cavity 11 is larger than that of the second cavity 21, the first box 1 is fitted outside the second box 2; conversely, in other embodiments, if the diameter of the second cavity 21 is larger than that of the first cavity 11, the second box 2 can be fitted outside the first box 1, and there is no restriction here.

[0042] The first housing 1 has a first column 12 and a second column 13 arranged at intervals inside. The first column 12 has a through-hole first groove 121 to form a condensate drainage channel, and the second column 13 has a through-hole second groove 131 to form a rainwater drainage channel. Preferably, the first column 12 and the second column 13 are both arranged vertically in the up-down direction and have the same height. The top of the first housing 1 also has a condensate collection interface 14 and a rainwater collection interface 15. The condensate collection interface 14 is connected to the top of the first groove 121, and the rainwater collection interface 15 is connected to the top of the second groove 131.

[0043] Preferably, the condensate collection interface 14, rainwater collection interface 15, first column 12, and second column 13 on the first box body 1 are all integrally formed.

[0044] Furthermore, the interior of the second housing 2 is provided with a third column 22, and the interior of the third column 22 has a through third groove 221 to form a water outlet channel. Preferably, the third column 22 extends vertically in the up-down direction. The bottom of the second housing 2 is provided with a water outlet 24, which communicates with the bottom of the third groove 221.

[0045] Preferably, the third column 22 and the water outlet 24 on the second box 2 are integrally formed.

[0046] Therefore, by splitting the box into a first box 1 and a second box 2, it is not only convenient to process the condensate drainage channel and rainwater drainage channel in the first box 1, as well as the water outlet channel in the second box 2, but also convenient to install and disassemble the box, thus making it easier to clean.

[0047] See Figure 2-3 The condensate collection box also includes a connector 3 for connecting the first box body 1 and the second box body 2; preferably, the connector 3 is an annular structure and is sleeved on the second box body 2. The connector 3 has a through hole 32 inside, and the outer wall of the second box body 2 is provided with a limiting protrusion 23. The connector 3 is sleeved on the outer periphery of the second box body 2 through the through hole 32 and abuts against the limiting protrusion 23 to achieve limiting. The inner side wall of the connector 3 also has an internal thread 31, and the bottom outer periphery of the first box body 1 also has an external thread 16 that matches the internal thread 31. When the connector 3 is threadedly connected to the external thread 16 on the first box body 1 through its internal thread 31, the connection and fixation between the first box body 1 and the second box body 2 can be achieved.

[0048] In addition, this utility model also provides a gas wall-hung boiler, including the aforementioned condensate collection box for the wall-hung boiler.

[0050] (I) The condensate collection box for wall-mounted boilers of this utility model has a height difference between the top of the water outlet channel and the bottom of the condensate guide channel, and between the top of the water outlet channel and the bottom of the rainwater guide channel. This forms a double water seal structure, thereby solving the problem of indoor air flowing back into the machine to participate in combustion due to the pressure difference between the indoor and outdoor areas of the machine, thus avoiding the consumption of indoor air by the user and reducing safety hazards.

[0051] (II) The condensate collection box for wall-hung boilers of this utility model sets the condensate flow channel, rainwater flow channel and water outlet channel in the collection chamber. Since the entire condensate collection box adopts only one cavity design, the external size of the parts is greatly reduced, which facilitates its installation inside the whole machine and makes the overall size of the machine more compact.
